[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figures 1-7 A polyethylene plastic granule cutting device for preventing adhesion includes a body 1. The body 1 has installation ports on both sides. A fixed plate 2 is fixedly installed in one installation port, and a rotating rod 3 is rotatably installed in the other installation port. The fixed plate 2 has multiple material inlets 4 on its circumferential surface. An electric push rod 5 is fixedly installed at one end of the rotating rod 3 inside the body 1. An installation rod 6 is fixedly installed on the drive shaft of the electric push rod 5. Multiple cutting blades 7 are fixedly installed on the circumferential surface of the installation rod 6.

[0026] Multiple guide plates 8 are staggered and inclined inside the machine body 1 and fixedly connected by multiple connecting rods. A discharge port 9 is opened at the bottom of the machine body 1. The multiple guide plates 8 are vertically slidably arranged inside the machine body 1 via a telescopic component, which includes multiple spring rods 17 and an L-shaped mounting plate 18 fixedly installed at the top of the spring rods 17. A rectangular groove is opened on the inner wall of the machine body 1. The bottom ends of the multiple spring rods 17 are fixedly connected to the bottom of the rectangular groove. The top of the mounting plate 18 is fixedly connected to the lower surface of one of the guide plates 8. A rotating opening is opened on the side wall of the machine body 1. A rotating shaft 10 is rotatably installed inside the rotating opening. A cam 11 is fixedly sleeved at one end of the rotating shaft 10. A groove 12 for the cam 11 to enter is opened on the lower surface of the guide plate 8 above the cam 11. When the cam 11 is not in contact with the groove wall of the groove 12, the top of the groove 12 is in contact with... The distance between the rotating shafts 10 is less than the length of the cam 11. One end of the rotating rod 3 is fixedly sleeved with a drive sprocket 13, and one end of the rotating shaft 10 is fixedly sleeved with a driven sprocket 14. A chain 15 is meshed and wound on the drive sprocket 13 and the driven sprocket 14. The rotating rod 3 is controlled to rotate by a drive assembly. The drive assembly includes a mounting shell 19 and a drive motor 20 fixedly installed in the mounting shell 19. The mounting shell 19 is fixedly installed on one side of the machine body 1 and covers the drive sprocket 13, the driven sprocket 14, and the chain 15. The mounting shell 19 can protect the drive sprocket 13, the driven sprocket 14, the chain 15, and the drive motor 20, preventing them from being exposed to the outside and easily damaged by external forces. The output shaft of the drive motor 20 is fixedly connected to one end of the rotating rod 3. An opening is provided on the surface of the machine body 1, and a door 16 is rotatably installed in the opening.

[0027] When cutting plastic strips, first rotate the machine door 16 to close the passage. At this time, the side walls of the multiple guide plates 8 will slide in contact with the inner wall of the machine body 1 and the surface of the machine door 16. Then, the plastic strip to be cut is passed through multiple passages 4 and fed at a uniform speed by the feeding mechanism (not shown, it belongs to the prior art and its working principle will not be described in detail here). At the same time, the drive motor 20 is started, controlling the rotating rod 3 to rotate the electric push rod 5 and the mounting rod 6, so that the multiple cutting blades 7 cut multiple plastic strips. During this process, the rotating shaft 10 will rotate the cam 11 under the transmission action between the driving sprocket 13, the driven sprocket 14 and the chain 15. The cam 11 will intermittently enter the groove 12 and abut against the groove wall of the groove 12. When the end of the cam 11 away from the rotating shaft 10 enters the groove When the cam 12 abuts against the wall of the groove 12, the multiple guide plates 8 move upward and the multiple spring rods 17 stretch. When the cam 11 rotates out of the groove 12, the pressure force exerted by the cam 11 on the multiple guide plates 8 disappears, and the multiple guide plates 8 will quickly move downward and reset under the elastic potential energy of the multiple spring rods 17. That is, as the cam 11 rotates, the multiple guide plates 8 will undergo high-frequency vertical vibration. The cut particles will fall onto the guide plates 8 under their own gravity and roll downward along the inclined surface of the multiple guide plates 8, and finally be discharged from the outlet 9. The particles continuously jump on the guide plates 8. The mechanical force generated by this high-frequency vibration can effectively destroy the adhesion between particles caused by heat melting and stickiness, greatly improving the anti-sticking effect. No additional electric drive device is required, and no additional electricity cost is generated.

[0028] The top of the machine body 1 is equipped with an air-cooling component, which is used to cool the cut particles. The air-cooling component includes a mounting cover 21 fixedly installed on the top of the machine body 1 and a fan 22 installed inside the mounting cover 21. The top of the machine body 1 has an air inlet that communicates with the inside of the mounting cover 21. The fan 22 is tilted and faces the fixed plate 2.

[0029] During the process of the cutting blade 7 rotating and cutting the plastic strip, the fan 22 can be turned on to blow air towards the cutting blade 7 and the fixed plate 2, so as to quickly cool the cut particles, reduce the particle temperature, and reduce the adhesion caused by excessive temperature.

[0030] Both the cutting blade 7 and the guide plate 8 are coated with an anti-stick coating made of polytetrafluoroethylene. The anti-stick coating reduces the adhesion between the particles and the contact surfaces of the cutting blade 7 and the guide plate 8.

[0031] In this invention, during the cutting of plastic strips, multiple guide plates 8 will reciprocate vertically in cooperation with the telescopic component and the cam 11, causing the cut particles to continuously bounce on the guide plates 8. The mechanical force generated by this high-frequency vibration can effectively destroy the adhesion between particles caused by heat melting and stickiness, greatly improving the anti-sticking effect.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
