Description:
Waste plastic products and films are materials that are not easily degradable and discard the environment that is likely to cause pollution. Its recycling is an important part of environmental protection. The squeezing granulator, as a machine integrating washing, dewatering and granulation, plays a very important role in the process of processing plastic products. Solve the problem of difficult dehydration of traditional soft film or filamentary plastics. In traditional centrifugal dehydrators, the final product dryness is only 15-20%. If multi-stage air delivery and hot air drying are used, because the drying time is too short, there will still be at least 10% moisture and consume a lot of electricity. As a result, the operating cost of the customer's recycled materials is too high, and the finished product is difficult to be competitive in the market! The squeezing granulator was born under this background. It can easily control the moisture of the cleaned material below 3%. At the same time, it can also control plastic film, tons of bags, diapers, etc. that are traditionally difficult to dehydrate. The filamentous plastic is semi-plasticized into granules, which improves its bulk density, facilitates the granulation of the subsequent equipment, and can also replace the traditional agglomerator! In this way, we have achieved the effect of killing four birds with one stone: saving electricity, saving labor, improving material dryness, and increasing output!

Working Principle:

Equipment composition structure: feed screw, feed bin, reducer, extrusion screw barrel, die head, air-cooled die face pelletizing system, cooling fan, storage bin, drainage system, control cabinet! The control system of the equipment is manufactured by the European CE standard design machine! The squeezing granulation system.
It has an interlock protection system. When the main motor is over-current, the control system will send out an audible and visual alarm, and at the same time automatically stop the screw feeder from feeding to protect the main motor from running smoothly! The pelletizing system is equipped with a safety limit switch. When the pelletizing cavity is opened, the cutter is replaced, and the maintenance is performed, the control system is interlocked
All operation buttons are prohibited from starting to protect the safety of maintenance personnel!
The working process of the equipment is: the material enters the extrusion screw and screw barrel from the inlet, and the extrusion screw squeezes the material to the outlet. In this process, the plasticized material is squeezed out, the water flows out from the leaking tank, and the pelletizing knife cuts the extruded semi-plasticized dry plastic into pellets. The fan conveys the granular material to Silo while cooling the cut plastic particles.
The general processing materials are PE, PP, BOPP, PVC, PS material film, and also can be nylon fishing net and diapers. At the same time, it can also be used as a means of processing paper pulp, and the squeezed and pelletized paper pulp can be used as a power generation combustion material in a power plant.

Reducer:

The motor and the hardened gear reducer are connected by a belt.
Because the squeezing process requires a very large torque, which can not be supported by ordinary reducers, and the gear teeth are easily broken, a hard-toothed reducer is selected.
Hard tooth surface deceleration is generally a three-stage transmission, using involute cylindrical helical gears. The gear is made of high-strength low-carbon alloy steel by carburizing and quenching. The tooth surface has high hardness. The gear adopts CNC grinding technology, high precision, good contact, high transmission efficiency, stable operation, low noise; small size and lightweight, Long service life and high carrying capacity. The motor can be adjusted forward and reverse through the control system. When the material is stuck, the current will be too large. At this time, the motor will automatically stop and will reverse in the next operation, and the stuck material can be exited.
In order to ensure the safe and stable 24-hour continuous operation of the reducer, and at the same time to ensure that the sealing ring does not leak oil due to high temperature, the reducer adopts a heat exchanger water-cooled oil circulation system!

Squeeze Screw Barrel
The structure and operation principle of the main shaft is similar to the screw feeder, and the material is pushed in the spiral direction through the spiral fins on the shaft.
The main difference is that the front and rear shaft diameters of the shaft have a certain difference-the front shaft is thinner, and the rear shaft is thicker. This results in that the front space is larger than the rear space in the enclosed space where the screw barrel is installed. In the process of advancing, the front space is gradually reduced, thereby generating a greater squeezing force, thereby squeezing the moisture out of the material.
The main shaft and reducer are mostly connected by European standard spline to ensure reliability.

The section hole of the spindle sleeve is shown in the figure.
The inside is small holes, and the outside is gradually large holes. Once the small holes inside are too large, it will easily cause the material to flow out along the small holes or even block the small holes. The outside gradually becomes larger, and the inner and outer holes form a larger pressure difference, and this pressure difference makes it easier for liquid to flow out.


In order to prevent the material from not moving forward with the rotation of the screw; at the same time, to avoid the large-area contact between the screw and the barrel and increase the friction, the barrel is designed with splines, which prolongs the service life of the screw and barrel and reduces the customer's operating cost!

Squeeze Screw
The connection of the extrusion screw spindle is mostly European standard spline connection to ensure its reliability, and can withstand greater torque compared with ordinary single keys!
The screw material is 38CrMoAl, the L/D ratio is 6:1, the screw is divided into three sections, the first part: the feeding section, the pitch is relatively wide, the screw groove is relatively deep, it is convenient to feed and eat, and simultaneously extrude Material; The second part: storage, dehydration and extrusion section, where the material is accumulated and squeezed, the moisture of the material is pressed out and drained along the drain hole of the screw cylinder; the third part: the extrusion plasticization section, The material is further squeezed and rubbed against each other to generate a lot of heat, and at the same time, the semi-plasticized material will further evaporate the moisture in the gasified material. When the material is extruded from the die, water vapor will evaporate from the semi-plasticized high-temperature material. The material is discharged so as to ensure that the water vapor content in the material does not exceed 3%; the fourth part is: the positioning section, the extrusion screw bears huge radial force during the process of extruding and pushing the material, backward thrust and torque, screw Both ends must support each other, otherwise there is a risk of shaft breakage. Graphene wear-resistant copper bearings are installed here to ensure the stability of the screw.

Die Head

The die head consists of a die face, a perforated plate, a water circulation cooling system, and a graphene wear-resistant bearing system! The perforated plate is installed in the front section of the die face!
The function of the perforated plate is to prevent the material from being quickly squeezed out of the template by the screw, to prevent the material from generating heat due to insufficient friction to semi-plasticize the material, and to prevent the squeezing force from being too small to remove the excess water in the material! The discharge speed of the material can be controlled by the diameter of the discharge hole of the perforated plate, so as to adapt to different materials! The diameter of the general film type is: 12mm, ton bags and other relatively solid materials with poor fluidity, the diameter of the hole is: 14mm! The perforated plate also has an important role as a wear-resistant liner to prevent the material from rubbing against the template and causing replacement Templates, thereby reducing the cost of customer wearing parts, reducing customer operation and maintenance costs!
The water circulation cooling system prevents the material from generating too much heat due to excessive friction, completely melting the material, and taking away the excess heat with water! The system is equipped with a thermocouple to detect the temperature of the material. When the temperature exceeds the set value, the temperature control system will give a signal to the solenoid valve, automatically open the water valve, cool the plasticization section of the die and the screw barrel, reduce the temperature, and avoid pelletizing, The plastic particles stick together!
The stencil material is dying steel, blackened and heat-treated to enhance wear resistance. When the material is PE, PP, HDPE, BOPP, CPP and other film materials, the size of the discharge hole is controlled between 10-12mm in diameter. When the material is PP ton bag, diaper and other materials, this material is very strong, has poor fluidity, and generates a lot of heat due to friction, avoiding excessive temperature and excessive melting of the material, speeding up the discharge speed and controlling the size of the discharge hole The diameter is between 12-16mm, and the number of discharge holes should be reduced by about 30%.

Die Face and Cutting Blade
In the process of extruding the material in a long strip, the pelletizing knife continuously rotates to cut the strip to form a pelletized finished product. The power source of the pelletizer is an AC motor connected to a worm gear reducer. The motor base can be moved back and forth to facilitate tool change, maintenance and other operations.
The upper part of the pelletizing knife cover can be opened for knife setting and adjustment after the base is fixed.
The cutting speed adopts ABB or Delta frequency conversion speed regulation; we adopt the latest design scheme imported from Japan, the template and the cutting system are designed separately, which is convenient for maintenance and more stable!

Bottom Leaking Groove

The water generated during the squeezing process is drained from the leaking tank. Due to the particularity of the water quality, the leaking tank is mostly made of stainless steel to prevent rust and corrosion.

Air Delivery System
The air delivery system uses a high-pressure centrifugal fan. The blades of the centrifugal fan exert power on the gas during the rotation process to increase the pressure and speed of the gas. The gas is discharged from the exhaust port along the blade channel under the action of centrifugal force. The airflow moves upwards and brings the material into the air outlet at the same time. Then the material will enter the storage bin along with the airflow. At the same time, the air takes away the heat of the material to achieve the purpose of cooling.

The storage bin in the picture is equipped with a simple cloth bag for dust removal, which has a high degree of integration. The two discharge ports can be switched through the openings to facilitate the continuous collection of materials. If the processed material is completely melted, there may be occasions where the temperature cannot be effectively reduced, which will cause the finished material to agglomerate and have to be reprocessed and broken. At this time, you can choose to add another level of air delivery system to cool, let the air take away more heat, and perform multiple cooling to achieve expectations. The effect is to prevent plastic particles from sticking together.
