[0002] Plastic bottles are a resource that can be recycled and reprocessed. In the process of recycling and reprocessing, they usually need to be crushed first. However, since plastic bottles are often used to hold beverages, air or liquid often remains inside them when they are recycled. In addition, the surface of plastic bottles is relatively smooth, which makes it difficult for traditional crushers to quickly bite these plastic bottles when crushing. In particular, under the drive of the crushing roller, the plastic bottles may bounce around in the crusher, which seriously reduces the crushing efficiency of the crusher. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a plastic crusher for plastic processing, which helps to improve crushing efficiency.

[0030] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0031] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0032] As shown in the accompanying drawings, a plastic crusher for plastic processing comprises a housing 1, in which a compression chamber 11 and a crushing chamber 12 are arranged from top to bottom, a compression mechanism 2 is arranged in the compression chamber 11, a crushing mechanism 3 is arranged in the crushing chamber 12, and a blocking plate 4 is arranged between the compression chamber 11 and the crushing chamber 12;

[0033] The compression mechanism 2 includes a moving plate 21 and a pressing plate 22 which are parallel to each other. A plurality of puncture needles 23 are evenly distributed on one end of the moving plate 21 close to the pressing plate 22. A plurality of avoidance holes 221 for the puncture needles 23 to pass through are opened on the pressing plate 22. An electric push rod 24 is connected to the end of the moving plate 21 which is opposite to the pressing plate 22. A first elastic member 25 is connected between the moving plate 21 and the pressing plate 22. The first elastic member 25 keeps the moving plate 21 and the pressing plate 22 away from each other.

[0034] The movable plate 21 has a pressed state and a released state;

[0035] One end of the blocking plate 4 is hinged to the housing 1, and the blocking plate 4 has a closed state and an open state; a locking assembly 5 capable of keeping the blocking plate 4 in the closed state is provided on the housing 1, and the locking assembly 5 has a locked state and an unlocked state;

[0036] The moving plate 21 is linked with the blocking plate 4 and the locking assembly 5 respectively;

[0037] When the movable plate 21 is in a compressed state, the locking assembly 5 is in an unlocked state, and the blocking plate 4 is in an open state;

[0038] When the moving plate 21 is in the released state, the locking assembly 5 is in the locked state, and the blocking plate 4 is in the closed state.

[0039] When the blocking plate 4 is in a closed state, the blocking plate 4 is in a horizontal position, and the compression chamber 11 is not connected to the crushing chamber 12; when the locking assembly 5 is in an unlocked state, the blocking plate 4 rotates to a vertical position under the action of gravity, and the compression chamber 11 is connected to the crushing chamber 12.

[0040] During operation, when the movable plate 21 is in a released state, the locking assembly 5 is in a locked state, and the blocking plate 4 is in a closed state, at which time the plastic bottle is poured into the compression chamber 11. Next, the electric push rod 24 drives the movable plate 21 to transition to a compressed state, on the one hand, so that the extrusion plate 22 squeezes the plastic bottle, and on the other hand, the puncture needle 23 passes through the avoidance hole 221 to pierce the plastic bottle to complete the compression of the plastic bottle. When the movable plate 21 is in a compressed state, the locking assembly 5 is in an unlocked state, and the blocking plate 4 is in an open state. Then, the electric push rod 24 drives the movable plate 21 to restore the released state, thereby releasing the compressed plastic bottle. At the same time, since the blocking plate 4 is in an open state, the compressed plastic bottle falls into the crushing chamber 12 under the action of gravity.

[0041] Preferably, a guide post 26 is provided at one end of the extrusion plate 22 close to the movable plate 21 , and a guide hole slidably connected to the guide post 26 is opened on the movable plate 21 .

[0042] Preferably, the locking assembly 5 includes a locking pin 51 slidably connected to the shell 1, a second elastic member 52 is connected between the locking pin 51 and the shell 1, the second elastic member 52 makes the locking pin 51 tend to remain in a locked state, a follower 53 is slidably connected to the outer wall of the shell 1, and a first inclined portion 531 acting on the locking pin 51 is formed at one end of the follower 53 close to the locking pin 51, a third elastic member 54 is connected between the follower 53 and the shell 1, the third elastic member 54 makes the follower 53 tend to stay away from the locking pin 51, and an active member 55 is provided on the telescopic rod of the electric push rod 24, and a second inclined portion 551 is provided on the active member 55 acting on the end of the follower 53 facing away from the locking pin 51.

[0043] Preferably, a ratchet 41 is provided on the blocking plate 4 , and when the blocking plate 4 is in a closed state, the straight side of the ratchet 41 abuts against the bottom end of the locking pin 51 .

[0044] Specifically, when the electric push rod 24 drives the moving plate 21 to change to the pressed state, the second inclined portion 551 on the active member 55 pushes the driven member 53 to move closer to the locking pin 51, so that the first inclined portion 531 on the driven member 53 pushes the locking pin 51 away from the blocking plate 4, so that the locking pin 51 is disengaged from the ratchet 41. Then, under the action of gravity, the blocking plate 4 rotates to a vertical position.

[0045] When the electric push rod 24 drives the moving plate 21 to the released state, the moving plate 21 drives the blocking plate 4 to rotate to the horizontal position through the ratchet 41. In this process, the inclined side of the ratchet 41 pushes the locking pin 51 to move away from the blocking plate 4. When the ratchet 41 rotates to the horizontal position, the force of the second elastic member 52 causes the locking pin 51 to return to the top of the ratchet 41, so that the straight side of the ratchet 41 abuts against the bottom end of the locking pin 51 again.

[0046] Preferably, the pulverizing mechanism 3 includes a pulverizing roller 31 rotatably connected to the housing 1 , and a reduction motor 32 transmission-connected to the pulverizing roller 31 .

[0047] Preferably, the side wall of the housing 1 is provided with a water guide hole 13 connected to the bottom of the compression chamber 11, and the water guide hole 13 is connected to the water guide groove 6. In the process of compressing the plastic bottle, most of the liquid squeezed out of the plastic bottle will be discharged to the outside through the water guide hole 13 and the water guide groove 6, which helps to reduce the amount of liquid entering the crushing chamber 12, thereby facilitating the subsequent collection and treatment of plastic debris.
