[0043] Embodiment 2

[0044] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.12 The extrusion assembly includes two groups of rotating tubes 205 rotatably arranged on the top of the pre-crushing chamber 200 and two groups of rotating columns 213 rotatably arranged at the bottom of the pre-crushing chamber 200. Multiple groups of upper extrusion leaves 206 are fixedly arranged on the outside of the rotating tubes 205. The upper extrusion leaves 206 can squeeze the plastic put into the pre-crushing chamber 200 downward to increase the shredding effect of the plastic. Two groups of top plates 215 are fixedly arranged on the top of the pre-crushing chamber 200. Both ends of the rotating tubes 205 pass through the inside of the top plates 215. A support rod 305 is rotatably arranged on the outside of the top plates 215. A second rotating wheel 231 is fixedly arranged on the outside of the support rod 305. A first rotating wheel 230 is fixedly arranged on the outside of the rotating tubes 205. The first rotating wheel 230 and the second rotating wheel 231 can make the two groups of rotating tubes 205 and the multiple groups of upper extrusion leaves 206 on the two groups of rotating tubes 205 rotate in opposite directions. A conveyor belt 309 is sleeved between the support rod 305 and the rotating tubes 205.

[0045] Two sets of support frames 216 are fixedly provided on the other side of the side baffle box 204, a rotating rod 207 is rotatably provided inside the support frame 216, two sets of first bevel gears 217 are fixedly provided outside the rotating rod 207, multiple sets of lower extrusion leaves 210 are fixedly provided outside the rotating column 213, and the lower extrusion leaves 210 can squeeze the plastic toward the direction of the lower cutter 214 to increase the cutting effect of the plastic, a second bevel gear 222 is fixedly provided at one end of the rotating column 213, and the second bevel gear 222 is meshed with the first bevel gear 217, and a first transmission belt 208 is sleeved between the rotating rod 207 and the rotating tube 205;

[0046] The lower extruding leaf 210 has a plurality of grooves formed therein, and a retractable plate 212 is disposed inside the groove. When the end of the retractable plate 212 hits the slot hole on the side of the pre-crushing chamber 200, the retractable plate 212 retracts into the groove or extends outward. Two sets of connecting springs 223 are fixedly disposed between the rotating column 213 and the inner wall of the groove.

[0047] A mounting motor 104 is fixedly provided on the front of the crushing chamber 100, and the mounting motor 104 can drive the screw 401, the rotating tube 205, the upper extrusion blade 206, the rotating column 213, the lower extrusion blade 210, the telescopic plate 212 and the stirring frame 306 to rotate. The working end of the mounting motor 104 extends to the end of the crushing roller 105, and a driving shaft 203 is fixedly provided at the end of the crushing roller 105. A second transmission belt 209 is sleeved between the driving shaft 203 and the rotating tube 205.

[0048] The pre-crushing mechanism of the present invention can, during use, shred some relatively large plastics entering the crushing chamber 100 for crushing into relatively small plastics in advance, cut the plastics horizontally left and right by the saw blade 211, and cut the plastics horizontally front and back by the cutter 214, so that relatively large plastics are cut into relatively small plastics, and the plastics placed in the pre-crushing chamber 200 can be squeezed downward by the rotating upper squeezing leaves 206 and lower squeezing leaves 210 and the telescopic plate 212, so that the plastics can be pre-crushed conveniently, so that the plastics entering the crushing chamber 100 can be conveniently crushed by the two sets of crushing rollers 105, thereby improving the crushing efficiency of the crusher for plastics, and further improving the efficiency of the entire production line.

[0049] During use, the motor 104 is turned on to drive the two groups of crushing rollers 105 to rotate, and the drive motor 201 is turned on. The drive motor 201 drives the worm 219 to rotate, thereby driving the cutter 214 to rotate at a high speed. When the worm 219 rotates, it will drive the worm wheel 220 meshing with it to rotate, thereby driving the movable rod 218 to rotate. The movable rod 218 drives the T-shaped wheel 228 to rotate through the third transmission belt 221. At this time, the T-shaped column 227 located on the T-shaped wheel 228 rotates and drives the connecting plate 226 to move. At this time, the T-shaped column 227 on the convex plate 224 and the T-shaped column 227 located on the convex plate 224 can be driven by the connecting plate 226 to reciprocate in the left and right directions, thereby driving the connecting plate 225 and the saw blade 211 to reciprocate in the left and right directions. The rotating crushing roller 105 drives the driving shaft 203 to rotate, and the driving shaft 203 drives the rotating tube 205 located on the left side of the pre-crushing chamber 200 to rotate through the second transmission belt 209, and then the rotating tube 205 on the left side drives the first rotating wheel 230 to rotate, and the first rotating wheel 230 drives the second rotating wheel 231 to rotate, which can drive the support rod 305 to rotate, and then the rotating support rod 305 drives the rotating tube 205 located on the right side of the pre-crushing chamber 200 to rotate through the conveyor belt 309, so that the two groups of rotating tubes 205 are rotated toward the middle part of the pre-crushing chamber 200, thereby driving the upper extrusion blades 206 to rotate, so that after the subsequent plastic enters the pre-crushing chamber 200, the two groups of upper extrusion blades 206 will squeeze the put-in plastic in the downward direction, thereby increasing the cutting effect of the saw blade 211 on the plastic;

[0050] The rotating tube 205 located on the left side of the pre-shredding chamber 200 rotates while driving the rotating rod 207 to rotate through the first transmission belt 208, thereby driving the two sets of first bevel gears 217 on the rotating rod 207 to rotate. The rotation of the first bevel gears 217 drives the second bevel gears 222 to rotate, thereby driving the two sets of rotating columns 213 to rotate in opposite directions, so as to facilitate the subsequent squeezing of the plastic toward the direction of the lower cutter 214, thereby increasing the cutting effect of the cutter 214 on the plastic;

[0051] When pre-shredding is performed, the plastic is placed in the pre-shredding chamber 200, and then the plastic is squeezed toward the direction of the lower saw blade 211 by the rotating upper squeezing leaf 206, so that the plastic passes through the saw blade 211, and the saw blade 211 cuts the plastic horizontally to the left and right, thereby increasing the effect of the saw blade 211 on the horizontal cutting of the plastic to the left and right. Then, the plastic falls onto the cutter 214, and the cutter 214 cuts the plastic horizontally to the front and back. At the same time, the two sets of rotating lower squeezing leaves 210 and the telescopic plate 212 can squeeze the plastic toward the lower cutter 214, thereby increasing the effect of the cutter 214 on the horizontal cutting of the plastic to the front and back. When the telescopic plate 212 is driven by the 10 to rotate, it can be compressed when it hits the slot hole on the side of the pre-crushing chamber 200, and moves into the groove inside the downward extruding leaf 210. At this time, the connecting spring 223 begins to compress, and can be reset and extended when it is separated from the slot hole. The connecting spring 223 is reset, and the rotating lower extruding leaf 210 and the telescopic plate 212 can block some splashing plastics, and can also reduce the size of the slot hole opened on the side of the pre-crushing chamber 200, which can reduce the amount of some plastics splashing into the side baffle box 204 during the crushing process, so that the plastics can basically be shredded by the cutter 214, thereby increasing the shredding effect.

[0052] Embodiment 3

[0053] Based on Example 2, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Fig.10 , Fig.11 and Fig.12 The side baffle box 204 is provided with a spray disinfection component, which includes a box body 300 and a fixed tube 303 fixed on the front of the side baffle box 204. A rotating joint 302 is provided between the rotating tube 205 and the fixed tube 303. The rotating rotating tube 205 can be connected to the fixed tube 303 through the rotating joint 302. A suction pipe 308 is fixedly provided on the fixed tube 303, and the end of the suction pipe 308 extends to the inside of the box body 300. A water pump 304 is provided on the box body 300. A plurality of spray holes 301 are opened on the outside of the rotating tube 205;

[0054] A stirring frame 306 is rotatably disposed inside the box body 300 , and a fourth transmission belt 307 is sleeved between the end of the stirring frame 306 and the support rod 305 .

[0055] The present invention uses a designed spray disinfection component. During the crushing process, multiple groups of spray holes 301 opened on the rotating tube 205 spray disinfectant into the pre-crushing chamber 200 to disinfect the plastic in the pre-crushing process and the area around the crusher. The rotating rotating tube 205 drives the spray holes 301 to rotate to increase the spray disinfection effect on the pre-crushing chamber 200 and the surrounding area, sterilize and deodorize the plastic and the area around the crusher, etc. At the same time, the sprayed disinfectant can absorb dust generated in the process of crushing plastics, reduce dust diffusion, and improve the environment around the equipment.

[0056] During use, disinfectant is loaded into the box 300, and then the disinfectant in the box 300 is pumped into the rotating tube 205 through the suction tube 308, the fixed tube 303, and the rotating joint 302 by the water pump 304 in sequence, and then the disinfectant is sprayed outward from the multiple groups of spray holes 301 outside the rotating tube 205 to disinfect the plastic in the pre-crushing chamber 200 and the area outside the crusher. At this time, the spray holes 301 rotate with the rotating tube 205, and the sprayed disinfectant can further increase the disinfection effect. The rotating support rod 305 can drive the stirring frame 306 to rotate under the drive of the fourth transmission belt 307, and the disinfectant in the box 300 is evenly stirred by the stirring frame 306 to prevent the disinfectant from precipitating.

[0057] Embodiment 4

[0058] Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A screw rod 401 is rotatably arranged inside the feed hopper 101 , a nut seat 402 is arranged outside the screw rod 401 , a movable frame 403 is fixedly arranged outside the nut seat 402 , and a fifth transmission belt 400 is sleeved between the end of the screw rod 401 and the driving shaft 203 .

[0059] The present invention combines the designed screw rod 401, nut seat 402, movable frame 403 and fifth transmission belt 400, and drives the screw rod 401 to rotate by rotating the driving shaft 203, so that the nut seat 402 outside the screw rod 401 moves back and forth to move the plastics accumulated and blocked in the crushing chamber 100, so that the plastics are evenly distributed in the crushing chamber 100, thereby further improving the crushing effect of the plastics.

[0060] If accumulation and blockage occur during the process of the crushing roller 105 in the crushing chamber 100 crushing the plastic, stop putting the plastic into the pre-crushing chamber 200, then stop the installation motor 104, and then put the fifth transmission belt 400 on the driving shaft 203 on the screw rod 401, and then start the installation motor 104 to drive the screw rod 401 to rotate. The rotation of the screw rod 401 drives the nut seat 402 to move toward the front or back direction of the equipment, thereby driving the moving frame 403 to move and evenly move the plastic blocked in the crushing chamber 100 to reduce blockage. When the nut seat 402 moves to a suitable position, the installation motor 104 is reversed, thereby driving the screw rod 401 to reverse. At this time, the nut seat 402 drives the moving frame 403 to move in the opposite direction. This reciprocating process is repeated for many times to clear the blocked plastic. Finally, the installation motor 104 is stopped, and the fifth transmission belt 400 on the screw rod 401 is removed.

[0061] In this embodiment, gear bodies are fixedly mounted on the ends of the two groups of crushing rollers 105 , and the two groups of gear bodies are meshed with each other. A bottom frame is fixedly mounted on the bottom of the crushing chamber 100 .

[0062] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
