[0019] A crushing method using the plastic waste crushing device for plastic toy production as described above, comprising the following steps:

[0020] S1: Place the plastic toy waste to be crushed in the storage shell, push the arc-shaped push block inward, fix the position of the arc-shaped push block through the fixing bolt. When the arc-shaped push block moves, it pushes the second crushing knife inward. The second crushing knife drives the second slider to move through the second connecting rod. The first slider, the first connecting rod, and the first crushing knife are driven to move outward through the second teeth on the second slider, the gear column, and the first teeth on the first slider. The first crushing knife extends out of the cylindrical block;

[0021] S2: When the first slider moves outward, it drives the lower ring plate to move downward through the downward movement component, and then drives the vertical rod to move downward. The vertical rod drives the inclined plate and the storage shell to rotate downward through the connecting component. At this time, the rotating circular block is driven to rotate through the first gear and the second gear. The transfer material groove on the rotating circular block rotates to the position where the plastic toy waste in the storage shell enters the transfer material groove;

[0022] S3: Start the reduction motor. The output end of the reduction motor drives the cylindrical block to rotate through the rotating rod. The cylindrical block drives the first crushing knife and the second crushing knife to rotate. When the first crushing knife rotates a certain angle, it abuts against the arc surface of the arc-shaped push block. The first crushing knife retracts and the second crushing knife extends. The first crushing knife and the second crushing knife alternately extend and retract to crush the plastic toy waste during the rotation process. When the second crushing knife extends, it drives the vertical rod to move upward through the upward movement component. The vertical rod drives the inclined plate and the storage shell to rotate upward through the connecting component, and then drives the rotating circular block and the plastic toy waste in the transfer material groove to rotate through the first gear and the second gear, so that the plastic toy waste falls and is crushed by the first crushing knife and the second crushing knife. The first crushing knife and the second crushing knife alternately retract and extend multiple times to drive the inclined plate and the storage shell to reciprocate up and down, and then make the rotating circular block reciprocate, realizing frequent and small feeding, avoiding jamming of the first crushing knife and the second crushing knife caused by adding too much plastic toy waste at one time. Adding a small amount of plastic toy waste at a time enables the first crushing knife and the second crushing knife to fully crush the plastic toy waste and improve the crushing effect;

[0023] S4: When the storage shell rotates upward and downward, the first semi-cylinder reciprocates between multiple second semi-cylinders. When the first semi-cylinder abuts against the second semi-cylinder, the second semi-cylinder is compressed into the through hole. When the first semi-cylinder and the second semi-cylinder separate, the second semi-cylinder extends under the action of the spring and knocks on the storage shell to make the storage shell vibrate, which can accelerate the sliding of the plastic toy waste in the storage shell on the inclined plate and accelerate the feeding of the plastic toy waste;

[0024] S5: When the vertical rod moves upward, it drives the inverted cylinder upward through the circular plate and the moving rod. The upward movement of the annular tooth teeth drives the rotating gear to rotate, which in turn drives the arc-shaped baffle to rotate downward and separate from the screen plate. The crushed plastic toy waste passes through the screen holes of the screen plate and enters the material guiding trough for discharge. When the vertical rod moves downward, the arc-shaped baffle is driven by the annular tooth teeth to rotate upward and stick to the screen plate.

[0025] Advantages of the present invention:

[0026] 1. Push the arc surface push block to make it contact with the cylindrical block. The arc surface push block pushes the second crushing knife. The second crushing knife drives the first crushing knife to extend through the second tooth teeth on the second slider, the gear column, and the first tooth teeth on the first slider. Driven by the reduction motor, the cylindrical block, the first crushing knife, and the second crushing knife rotate to crush the plastic toy waste.

[0027] 2. During the rotation process, the first crushing knife and the second crushing knife alternately contract and extend multiple times, which can drive the inclined plate and the storage shell to reciprocate up and down, and then make the rotating circular block rotate reciprocally, realizing frequent and small-scale feeding. Avoiding adding too much plastic toy waste at one time causes jamming of the first crushing knife and the second crushing knife. Adding a small amount of plastic toy waste at a time enables the first crushing knife and the second crushing knife to fully crush the plastic toy waste, improving the crushing effect.

[0028] 3. When the storage shell rotates upward and downward, the first semi-cylinder reciprocates between multiple second semi-cylinders. When the first semi-cylinder and the second semi-cylinder are in contact, the second semi-cylinder is compressed into the through hole. When the first semi-cylinder and the second semi-cylinder are separated, the second semi-cylinder extends under the action of the spring and knocks on the storage shell to make the storage shell vibrate, which can accelerate the sliding of the plastic toy waste in the storage shell on the inclined plate and speed up the feeding of the plastic toy waste.

[0029] 4. When the vertical rod moves upward, it drives the inverted cylinder upward through the circular plate and the moving rod. The upward movement of the annular tooth teeth drives the rotating gear to rotate, which in turn drives the arc-shaped baffle to rotate downward and separate from the screen plate. The crushed plastic toy waste passes through the screen holes of the screen plate and enters the material guiding trough for discharge. When the vertical rod moves downward, the arc-shaped baffle is driven by the annular tooth teeth to rotate upward and stick to the screen plate, discharging the crushed plastic toy waste frequently for multiple times.

[0063] The present invention also provides a crushing method for a plastic waste crushing device for plastic toy production, including the following specific steps:

[0064] S1: Place the waste plastic toys to be crushed in the storage shell 302. Push the arc-shaped push block 108 inward and fix the position of the arc-shaped push block 108 through the fixing bolt 113. When the arc-shaped push block 108 moves, it pushes the second crushing knife 205 inward. The second crushing knife 205 drives the second slider 209 to move through the second connecting rod 207. The second slider 209 drives the first slider 208, the first connecting rod 206 and the first crushing knife 204 to move outward through the second teeth on the second slider 209, the gear column 210 and the first teeth on the first slider 208. The first crushing knife 204 extends out of the cylindrical block 104;

[0065] S2: When the first slider 208 moves outward, it drives the lower ring plate 215 to move downward through the downward movement component 213, and then drives the vertical rod 203 to move downward. The vertical rod 203 drives the inclined plate 301 and the storage shell 302 to rotate downward through the connecting component 309. At this time, the rotating circular block 307 is driven to rotate through the first gear 304 and the second gear 306. The transfer material groove on the rotating circular block 307 rotates to the position where the waste plastic toys in the storage shell 302 enter the transfer material groove;

[0066] S3: Start the reduction motor 201. The output end of the reduction motor 201 drives the cylindrical block 104 to rotate through the rotating rod 202. The cylindrical block 104 drives the first crushing knife 204 and the second crushing knife 205 to rotate. When the first crushing knife 204 rotates a certain angle, it abuts against the arc surface of the arc-shaped push block 108. The first crushing knife 204 retracts and the second crushing knife 205 extends. The first crushing knife 204 and the second crushing knife 205 alternately extend and retract to crush the waste plastic toys during the rotation. When the second crushing knife 205 extends, it drives the vertical rod 203 to move upward through the upward movement component 212. The vertical rod 203 drives the inclined plate 301 and the storage shell 302 to rotate upward through the connecting component 309. Then, the rotating circular block 307 and the waste plastic toys in the transfer material groove are driven to rotate through the first gear 304 and the second gear 306, so that the waste plastic toys fall and are crushed by the first crushing knife 204 and the second crushing knife 205. The first crushing knife 204 and the second crushing knife 205 alternately contract and extend many times, driving the inclined plate 301 and the storage shell 302 to reciprocate up and down, and then making the rotating circular block 307 reciprocate. It can realize frequent and small feeding, avoid jamming of the first crushing knife 204 and the second crushing knife 205 caused by adding too many waste plastic toys at one time. Adding a small amount of waste plastic toys at a time enables the first crushing knife 204 and the second crushing knife 205 to fully crush the waste plastic toys and improve the crushing effect;

[0067] S4: When the storage shell 302 rotates upward and downward, the first semi-cylinder 308a reciprocates between a plurality of second semi-cylinders 308b. When the first semi-cylinder 308a abuts against the second semi-cylinders 308b, the second semi-cylinders 308b are compressed into the through holes. When the first semi-cylinder 308a separates from the second semi-cylinders 308b, under the action of the spring 308e, the second semi-cylinders 308b extend and strike the storage shell 302 to vibrate the storage shell 302, thereby accelerating the sliding of the plastic toy waste in the storage shell 302 on the inclined plate 301 and accelerating the feeding of the plastic toy waste.

[0068] S5: When the vertical rod 203 moves upward, it drives the inverted cylinder 403 to move upward through the circular plate 401 and the moving rod 402. The upward movement of the annular tooth 408 drives the rotating gear 407 to rotate, thereby driving the arc-shaped baffle 405 to rotate downward and separate from the screen plate 111. The crushed plastic toy waste passes through the screen holes of the screen plate 111 and enters the guide trough 409 for discharge. When the vertical rod 203 moves downward, the arc-shaped baffle 405 is driven by the annular tooth 408 to rotate upward and adhere to the screen plate 111.
