The inner wall of the limit block is threadedly connected to a limit screw. The surface of the limit screw is threadedly connected to a limit frame.

[0007] The above technical solution, which uses a connecting plate to limit the connecting block and a limiting screw to limit the limiting block, enables convenient disassembly and assembly when the cutting tool is damaged and needs to be replaced or maintained. This makes the device more convenient to use and improves its overall practicality.

[0008] As a further improvement to the above solution, the inner wall of the connecting plate is fixedly connected to the output end of the first motor, and the limiting screw is located on both sides of the limiting block.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a cutting mechanism: after the plastic strip enters the device, a first motor is activated to rotate, simultaneously driving a connecting disc to rotate on the inner wall of a rotating sleeve. As the connecting disc rotates, the connecting block on its inner wall rotates accordingly, driving the cutting blade to rotate as well. This cuts the plastic strip into pellets. If the cutting blade is damaged due to prolonged use or other reasons, the limiting screws at both ends of the limiting block are rotated to release it from its position. The cutting blade then moves towards the limiting block, disengaging the connecting block from the connecting disc's limit and pulling the cutting blade upwards for subsequent replacement. This design, using a connecting disc to limit the connecting block and limiting screws to limit the limiting block, allows for convenient disassembly and assembly when the cutting blade needs replacement or maintenance, making the device more convenient to use and improving its overall practicality.

[0018] This invention utilizes a transmission mechanism: pulling a lever raises the auxiliary shaft, simultaneously raising the mounting blocks on both sides of the auxiliary shaft. At this point, the output end of the telescopic rod retracts, compressing the spring. After the auxiliary shaft separates from the power shaft, the plastic strip is pulled to the upper end of the power shaft. Releasing the lever allows the auxiliary shaft to slide back down under its own weight and the spring's action, contacting the power shaft again to clamp the plastic strip. After clamping, a second motor is activated to rotate the power shaft, thus bringing the plastic strip into the device. This design, using a lever to raise and lower the auxiliary shaft, provides convenient material loading, making the device more user-friendly. Attached Figure Description

The inner wall of the limiting block 106 is threadedly connected to a limiting screw 107. The surface of the limiting screw 107 is threadedly connected to a limiting bracket 108. The design of using the connecting plate 103 to limit the connecting block 104 and the limiting screw 107 to limit the limiting block 106 enables convenient disassembly and assembly when the cutting tool 105 is damaged and needs to be replaced or maintained, making the device more convenient to use and improving its overall practicality.

[0030] The inner wall of the connecting plate 103 is fixedly connected to the output end of the first motor 101, and the limiting screw 107 is located on both sides of the limiting block 106.

[0031] The transmission mechanism 2 includes a second motor 201. The output end of the second motor 201 is fixedly connected to a power shaft 202. A connecting frame 203 is rotatably connected to the surface of the power shaft 202. A telescopic rod 204 is fixedly connected to the inner wall of the connecting frame 203. A spring 205 is sleeved on the output end of the telescopic rod 204. A mounting block 206 is fixedly connected to the output end of the telescopic rod 204. An auxiliary shaft 207 is rotatably connected to the inner wall of the mounting block 206. A pull rod 208 is rotatably connected to the surface of the auxiliary shaft 207. The design of using the pull rod 208 to drive the auxiliary shaft 207 to lift and lower achieves the function of conveniently feeding materials into the device, making the device more convenient to use.

[0032] Spring 205 is located at the upper end of mounting block 206, and the surface of mounting block 206 is slidably connected to the inner wall of connecting bracket 203.

[0033] The protective mechanism 3 includes a base 301, a protective shell 302 fixedly connected to the upper end of the base 301, a fixing plate 303 fixedly connected to the upper end of the protective shell 302, a hinge 304 fixedly connected to the upper end of the fixing plate 303, an opening and closing plate 305 fixedly connected to the side end of the hinge 304, a partition 306 fixedly connected to the inner wall of the protective shell 302, and a sliding plate 307 fixedly connected to the surface of the partition 306.

[0034] The lower end of the partition 306 is fixedly connected to the upper end of the base 301, the inner wall of the partition 306 is rotatably connected to the surface of the power shaft 202, the surface of the partition 306 is fixedly connected to the surface of the connecting frame 203, and the inner wall of the protective shell 302 is fixedly connected to the right end of the second motor 201.

[0035] The surface of the limiting block 106 is slidably connected to the inner wall of the partition 306, the rear end of the limiting frame 108 is fixedly connected to the front end of the partition 306, and the rear end of the rotating sleeve 102 is fixedly connected to the front end of the partition 306.

[0036] The implementation principle of the pelletizing device for a plastic granule production line in this application embodiment is as follows: When using the device, first pull the lever 208 to drive the auxiliary shaft 207 to rise, and at the same time drive the mounting blocks 206 on both sides of the auxiliary shaft 207 to rise. At this time, the output end of the telescopic rod 204 retracts, and the spring 205 is compressed. After the auxiliary shaft 207 rises and separates from the power shaft 202, the plastic strip is pulled to the upper end of the power shaft 202. Then, release the lever 208. At this time, the auxiliary shaft 207 slides down again under its own weight and the action of the spring 205 to contact the power shaft 202, thereby clamping the plastic strip. After clamping, start the second motor 201 to drive the power shaft 202 to rotate, thereby bringing the plastic strip into the device. The design of using the lever 208 to drive the auxiliary shaft 207 to rise and fall realizes the function of conveniently feeding the device, making the device more convenient to use. After the plastic strip enters the device, start the first motor 101 to rotate, and at the same time drive the connecting rod 204 to rise and fall. The receiving plate 103 rotates on the inner wall of the rotating sleeve 102. When the receiving plate 103 rotates, the connecting block 104 on its inner wall rotates with it, simultaneously driving the cutting blade 105 to rotate, thereby cutting the transmitted plastic strip into pellets. Then, the pellets slide out with the angle of the slide plate 307. If the cutting blade 105 is damaged due to prolonged use or other reasons, the limiting screws 107 at both ends of the limiting block 106 are rotated to release the limiting block 106. Then, the cutting blade 105 moves towards the limiting block 106, thereby causing the connecting block 104 to disengage from the limiting plate 103, thus pulling the cutting blade 105 upward for subsequent replacement. The design of using the receiving plate 103 to limit the connecting block 104 and the limiting screws 107 to limit the limiting block 106 allows for convenient disassembly and assembly when the cutting blade 105 is damaged and needs replacement or maintenance, making the device more convenient to use and improving its overall practicality.
