[0032] This part is based on Figure 1-10The working process expressed in 14 and 15 is: in the process of plastic granulation, in order to improve the efficiency of plastic granulation, when in use, the molten plastic raw material is circulated to the extrusion box 102 through the receiving frame 103, and then the extrusion seat 202 moves downward in the extrusion box 102 and extrude the raw material in the extrusion box 102, so that the extruded plastic raw material forms strips in multiple extrusion tubes 109 and flows out from the bottom in strips. At this time, the raw material flowing out of each extrusion tube 109 passes through the auxiliary frame 601, and then the sliding frame 301 relies on the two limiting frames 105 on the rear side to move and limit repeatedly horizontally, and then the multiple flow ports on the sliding frame 301 use the circular sharp surface on the upper side to repeatedly cut the extruded strip plastic raw material and flow out in granular form, forming a continuous cutting and granulation process, which is faster and more efficient than the cutting and granulation work of the prior art. In the process of plastic granulation, it is convenient to improve the efficiency of plastic granulation.

[0033] The front side of the extrusion box 102 is rotatably connected to a lead screw 104 , the lead screw 104 is transmission-connected to a concave frame 201 , and the rear side of the concave frame 201 is fixedly connected to the top of the extrusion seat 202 .

[0034] This part is based on Figure 1-10 The working process expressed in 14 and 15 is: when the extrusion seat 202 moves downward to extrude the plastic raw material, the output shaft of a motor is fixedly connected to the top of the screw 104 through a coupling, and the motor is fixedly connected to the front side of the extrusion box 102 by bolts. The driving motor rotates the screw 104, thereby controlling the concave frame 201 to move up and down, and synchronously drives the extrusion seat 202 to move up and down through the concave frame 201, thereby providing power for the extrusion work of the extrusion seat 202.

[0035] The bottom surface of the extrusion seat 202 is evenly provided with a plurality of grooves.

[0036] This part is based on Figure 1-10 The working process expressed in 14 and 15 is: a plurality of grooves are evenly arranged on the bottom surface of the extrusion seat 202 to increase the friction between the bottom surface of the extrusion seat 202 and the plastic raw material.

[0037] The rear side of the sliding frame 301 is fixedly connected to a right-angle frame 302, and the right side of the right-angle frame 302 is fixedly connected to an arc seat 303. A cam 107 is in contact with the right arc surface of the arc seat 303. The middle part of the cam 107 is fixedly connected to the rotating rod 106, and the rotating rod 106 is rotatably connected to the bottom of the extrusion box 102.

[0038] Two springs 304 are fixedly connected to the left rear of the sliding frame 301 . The two springs 304 are respectively sleeved on the two limiting frames 105 . The left sides of the two springs 304 are respectively fixedly connected to the left sides of the two limiting frames 105 .

[0039] Each of the springs 304 is a compression spring.

[0040] This part is based on Figure 1-10 The working process expressed in 14 and 15 is: when the sliding frame 301 is repeatedly moved laterally so that multiple flow ports can provide power for cutting and granulating the strip plastic raw materials extruded by each extrusion tube 109, when in use, the output shaft of a second motor is fixedly connected to the upper side of the rotating rod 106 through a coupling, and the second motor is fixedly connected to the bottom of the extrusion box 102 by bolts, driving the second motor to rotate the rotating rod 106, and when the rotating rod 106 rotates, the cam 107 is synchronously driven to rotate, so that when the cam 107 rotates, the shape of the cam 107 pushes the arc The seat 303, the arc seat 303 kicks the right-angle frame 302 and the sliding frame 301 at the bottom, and at the same time, presses the two springs 304. The elastic force of the two compression springs 304 allows the sliding frame 301 to return to its original position after being pushed, so that the arc seat 303 always maintains a fit with the cam 107, so that the repeated lateral movement of the sliding frame 301 allows multiple flow ports to provide power for cutting and granulating the strip plastic raw materials extruded by each extrusion tube 109. The structure is simple and efficient, making the plastic cutting and granulation work more efficient and quick.

[0041] A rectangular hole 110 is respectively provided on the right side of the bottom of each of the extrusion tubes 109 . An arc-shaped strip plate 401 is fixedly connected in each of the rectangular holes 110 . Each of the arc-shaped strip plates 401 is evenly provided with a plurality of small holes.

[0042] This part is based on Figure 1-15 The working process expressed therein is as follows: a rectangular hole 110 is respectively provided on the right side of the bottom of each of the extrusion tubes 109, and an arc-shaped strip plate 401 is respectively fixedly connected in each of the rectangular holes 110, and each of the arc-shaped strip plates 401 is evenly provided with a plurality of small holes, so that the strip-shaped plastic raw materials formed in each of the extrusion tubes 109 can be initially cooled and ventilated through the plurality of small holes on each of the arc-shaped strip plates 401, so that the subsequent cutting and granulation work can be performed more quickly and conveniently.

[0043] A docking box 504 is fixed and connected to each of the rectangular holes 110, and the middle parts of the outer sides of the multiple docking boxes 504 are evenly fixed and connected to the transverse tube 503. A connecting pipe 502 is fixed and connected to the middle part of the front side of the transverse tube 503, and the front side of the connecting pipe 502 is fixed and connected to the fan 501. The fan 501 is fixedly connected to the placement rack 108, and the placement rack 108 is fixedly connected to the bottom of the front side of the extrusion box 102.

[0044] This part is based on Figure 1-15 The working process expressed therein is: in order to facilitate further rapid cooling of the strip plastic raw material formed in each extrusion tube 109, so that the bottom of each extrusion tube 109 can be cut more quickly and efficiently through the flow port on the sliding frame 301, so that the plastic particles after cutting are accelerated to solidify, when in use, the fan 501 is driven so that the wind blown out by the fan 501 can be blown into the transverse pipe 503 through the connecting pipe 502, and the wind is diverted through the transverse pipe 503 to send the wind into each docking box 504, and then the wind is passed through the small holes of each arc-shaped strip plate 401 through each docking box 504 to quickly cool down and solidify the strip plastic raw material in each extrusion tube 109, so that the bottom of each extrusion tube 109 can be cut more quickly and efficiently through the flow port on the sliding frame 301, and the cutting is more convenient, preventing the raw materials from sticking.
