[0022] Example 1

[0023] Reference Figure 1-Figure 2 , a preferred embodiment of the utility model comprises a granulation box 1, wherein the granulation box 1 is divided into a stirring chamber and a granulation chamber by setting a partition 7, an extrusion chamber 12 is arranged in the granulation chamber, a transmission rod 10 is arranged in the extrusion chamber 12, a forming hole 16 is arranged on the right wall of the extrusion chamber 12, the transmission rod 10 passes through the extrusion chamber 12 and a mounting platform 17 is arranged, the mounting platform 17 is provided with a slot for installing a cutting tool 18, the mounting platform 17 is connected to the cutting tool 18 by a vertical snap-on structure, a horizontal clamping mechanism is arranged in the mounting platform 17, the horizontal clamping mechanism comprises a bidirectional threaded rod 22, both ends of the bidirectional threaded rod 22 are threadedly connected with a moving block 25, an L-shaped clamping plate 26 is fixedly connected to the moving block 25, the horizontal clamping mechanism also comprises a cross bar 24 arranged in the mounting platform 17, the cross bar 24 is slidably connected to the moving block 25, and a positioning bolt is arranged on the moving block 25, and a handle 23 is arranged at one end of the bidirectional threaded rod 22.

[0024] Specifically, the rotating handle 23 drives the bidirectional threaded rod 22 to rotate, and the rotation of the bidirectional threaded rod 22 drives the two moving blocks 25 to move inward or outward at the same time. The movement of the moving block 25 drives the L-shaped clamp 26 to move its position, and then the two L-shaped clamps 26 clamp and limit the left and right sides of the cutting tool 18, thereby preventing the cutting tool 18 from shaking left and right during operation. Among them, the surface of the cross bar 24 is set to be smooth, and the cross bar 24 provides a limit and support function for the movement of the moving block 25.

[0025] Furthermore, the vertical snap-fit ​​structure includes a fixed block 19 arranged on the cutting tool 18 and a mounting plate 28 arranged in the mounting platform 17, a spring 27 is fixedly arranged on the mounting plate 28, the spring 27 abuts against the bottom of the cutting tool 18, a slot is arranged on the fixed block 19, a connecting rod is arranged on the mounting platform 17, the connecting rod is movably connected to a snap-fit ​​plate 20 through a pin shaft 21, and the snap-fit ​​plate 20 matches the slot of the fixed block 19.

[0026] Specifically, in the process of installing the cutting tool 18, it is only necessary to press the cutting tool 18 to squeeze the spring 27, so that the spring 27 shrinks on the surface of the mounting plate 28. At this time, the clamping plate 20 is clamped in the clamping groove of the fixing block 19. After the cutting tool 18 is released, the clamping plate 20 is tightly clamped in the clamping groove of the fixing block 19 due to the rebound of the spring 27. (In the field of buckle technology, the clamping plate 20 is clamped in the clamping groove of the fixing block 19 to achieve fixation, which is a conventional technical means in this technical field and will not be described in detail.) Thus, the cutting tool can be fixed in the vertical direction, which is very convenient to install and greatly reduces the installation time.

[0027] When the cutting tool 18 is disassembled and replaced, the cutting tool 18 is pressed to shrink the spring 27 , and the clamping plate 20 is opened to realize the disassembly of the cutting tool 18 in the vertical direction.

[0028] To summarize, the utility model adjusts the positions of the two moving blocks 25 by rotating the bidirectional threaded rod 22 in the horizontal clamping mechanism, so that the moving block 25 drives the L-shaped clamping plate 26 to move to both sides of the cutting tool 18, and then the left and right sides of the cutting tool 18 are load-limited, and then the cutting tool 18 is fixed in the vertical direction by the fixed block 19, the clamping plate 20, the spring 17 and other structures in the vertical snap structure. When disassembling, it is only necessary to pry open the clamping plate 20 and rotate the handle 23 on the bidirectional threaded rod 22 to disassemble, thereby realizing the installation and disassembly of the cutting tool 18, greatly reducing the difficulty of replacing and repairing the cutting tool 18, and improving the maintenance efficiency of the cutting tool 18.

[0031] Specifically, the utility model drives the stirring rod 5 to rotate through the rotating shaft 12, and mixes the processing raw materials of the PET bottles entering the granulation box 1 through the stirring rod 5, so that the processing raw materials are mixed evenly. When the processing raw materials are mixed, the scraper 6 on the stirring rod 5 can scrape off the processing raw materials attached to the inner wall of the granulation box 1, so as to avoid the phenomenon of agglomeration of the processing raw materials on the inner wall of the granulation box 1, thereby improving the mixing effect of the processing raw materials, facilitating the subsequent granulation operation of the processing raw materials, and improving the granulation quality of the granulation device.

[0032] Furthermore, a second motor 11 is disposed on the outer wall of the granulation box 1 , and the second motor 11 is connected to the transmission rod 10 , and an extrusion plate 9 is movably connected to the surface of the transmission rod 10 .
