[0002] At present, plastic granulation is a common processing method used to process waste plastics or raw plastics into granular materials for subsequent reuse or processing. In the traditional plastic granulation process, it usually needs to go through multiple steps such as crushing, melting, and extrusion. Among them, the slitting link is a very crucial step.

Then, the cutting mechanism presses the extending plastic strip, thereby reducing the shaking generated during slitting and ensuring that the sizes of the cut plastic particles are uniform.

[0034] In the above embodiment, as a preferred solution, a water tank 2 is fixedly connected to the other side of the support frame 1 at the top of the pushing mechanism. A positioning groove 3 is provided on the inner side wall of the water tank 2. A pressure roller 4 is connected to the inner wall of the positioning groove 3 through a rotating shaft. One end of the water tank 2 is connected to a guiding roller 7 through a rotating shaft. A water storage tank 8 is inserted into the inner wall of the support frame 1 below the water tank 2. Through the setting of the water tank 2, it can be directly installed and fixed on the top of the support frame 1, thereby storing more water. After the plastic strip is extruded, it extends into the water tank 2, and the water is used to cool the plastic strip and make it take shape. The setting of the pressure roller 4 can ensure that the plastic strip is pressed into the water to ensure sufficient cooling of the plastic strip. Through the setting of the guiding roller 7, when the plastic strip is sent outwards, the plastic strip can be supported upwards, and the plastic strip can be assisted in conveying by its own rotation. Through the setting of the water storage tank 8, when the plastic strip is pulled outwards, the excess water can be dripped into the water storage tank 8, which is more convenient for the staff to handle.

The other end of the adjusting rod 12 is connected to the outer wall of the pressing plate 14 through a rotating shaft. Through the setting of the guide groove 11, the end of the adjusting rod 12 can be assisted to slide, and then the position of the adjusting rod 12 can be adjusted to change the inclination angle of the adjusting rod 12, so as to adjust the gap between the pressing plate 14 and the support frame 1, and then adjust the height of the pressing plate 14 according to the thickness of the plastic strip, and further adjust the gap between the conveyor belt 16 and the conveyor belt 10 to adjust the pressing degree, so as to avoid squeezing and deforming the plastic strip.

[0039] In the above embodiments, as a preferred solution, a fixing rod 13 is threadedly penetrated through the outer surface of the adjusting rod 12. One end of the fixing rod 13 penetrating into the adjusting rod 12 abuts against the inner side wall of the guide groove 11. Through the setting of the fixing rod 13, after the adjusting rod 12 is adjusted, the adjusted adjusting rod 12 can be fixed by using the fixing rod 13 to ensure the stability of the pressing plate 14.

Through the arrangement of the support rods 17, inside the conveyor 16 and the conveyor belt 10, the support rods 17 can be used to reduce the deformation degree of the conveyor 16 and the conveyor belt 10, thus ensuring the pressing stability of the conveyor 16 and the conveyor belt 10 on the plastic strips;

[0041] The support rod 17 includes a first support rod passing through the inner ring of the conveyor belt 10 and parallel to the first driving roller 9, and a second support rod passing through the inner ring of the conveyor 16 and parallel to the second driving roller 15. The first support rod abuts against the inner wall surface of the conveyor belt 10, keeping the upper surface of the conveyor belt 10 at the lower part of the gap. The second support rod abuts against the inner wall surface of the conveyor 16, keeping the lower surface of the conveyor 16 at the upper part of the gap.

[0042] In the above embodiments, as a preferred solution, one side of the top of the mounting base 18 is connected to a cover plate 21 through a hinge. The top of the support frame 1 is connected to a protective plate 22 through bolts above the cover plate 21. The bottom of the support frame 1 is fixedly connected to a collection tank 24 below the mounting base 18. Through the arrangement of the cover plate 21, it can be opened and closed above the mounting base 18, and thus can protect the motor 19 inside the mounting base 18 after being closed. The upper protective plate 22 can cover and protect the outside of the cutting knife 20, thereby reducing the situation of particle ejection during the cutting process.

[0043] In the above embodiments, as a preferred solution, motors 23 are fixedly installed on the outer sides of the support frame 1 and the pressing plate 14 respectively. The two motors 23 correspond to the first driving roller 9 and the second driving roller 15 respectively.

Through the arrangement of the three motors 23, the first driving roller 9, the second driving roller 15 and the guiding roller 7 can be driven to rotate respectively. The first driving roller 9 and the second driving roller 15 rotate synchronously in opposite directions, so that the conveyor 16 and the conveyor belt 10 can drive the plastic strips to be conveyed synchronously.

[0044] In the present utility model, the working steps of the device are as follows:

[0045] First, fill the water tank 2 with water at an appropriate temperature, about 60 °C. Then, pass the extruded plastic strips under the two pressure rollers 4 and then send them above the guiding roller 7. Through the rotation of the guiding roller 7, the guiding roller 7 assists in conveying the plastic strips outwards, and a small amount of water carried by the plastic strips will fall into the water storage tank 8;

[0046] Secondly, start two motors 23 to drive the first driving roller 9 and the second driving roller 15 to rotate relatively synchronously, which can drive the conveyor belt 10 and the conveyor 16 to operate, and feed the plastic strips passing through the guide roller 7 between the conveyor 16 and the conveyor belt 10, so as to press and convey the plastic strips outwards;

[0047] Then, start the motor 19, which can drive the cutting knife 20 to rotate, and then cut the fed plastic strips into particles, and then the collection tank 24 can send the cut particles outwards;

[0048] Finally, after use, turn off the motor 19 and the two motors 23, open the sealing plug 6, drain the waste water outwards, and then pull out the water storage tank 8 to treat the waste water.
