[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 7In the embodiment of the utility model, a plastic product recycling and pulverizing device includes a support base 1 and a pulverizer shell 2. The pulverizer shell 2 is fixedly connected to the upper end of the support base 1. A dust filter box 3 is fixedly connected to the edge of the lower end opening of the pulverizer shell 2. A discharge port 12 is opened on the side wall of one end of the dust filter box 3. A discharger 6 is fixedly connected to the edge of the opening of the discharge port 12. A dustproof cloth 5 is fixedly connected to the upper end of the inner wall of the discharge port 12. An opening groove 11 is opened on the other side wall of the dust filter box 3. A cover plate 4 is fixedly connected to the inner wall of the opening groove 11 by screws. Dustproof components are distributed on the dust filter box 3 and the base of the support base 1.

[0029] The dust prevention assembly includes a vibrating dust filter unit with a sieve plate 16 and a discharging unit with a push plate 8;

[0030] The vibrating sieve plate 16 is used to drive the plastic fragments accumulated on the upper end of the sieve plate 16 to vibrate and shift, so that the dust on the plastic fragments can pass through the filter holes on the sieve plate 16 and fall to the bottom end of the inner cavity of the dust filter box 3;

[0031] The push plate 8 is used to push the broken plastic pieces at the upper end of the discharge port 12 to discharge along the discharge device 6 when the screen plate 16 rises to the discharge port 12.

[0032] In this embodiment: in the dismantling and recycling of scrapped cars, when the plastic crusher is used to crush plastic parts such as bumpers, the staff puts the scrapped car plastic parts into the crusher. During the crushing process, a large amount of dust attached to the plastic parts is hit to generate a large amount of dust. The crushed plastic fragments and dust fall from the lower end outlet of the crusher housing 2 onto the sieve plate 16. During this process, the dustproof cloth 5 blocks the dust, so that the dust cannot fly out through the discharge port 12 and pollute the working environment. Part of the dust directly passes through the filter holes on the sieve plate 16 and falls to the lower end of the inner cavity of the dust filter box 3;

[0033] Afterwards, the small vibration motor 17 drives the screen plate 16 to vibrate up and down. During this process, the spring 15 continuously extends and contracts, and the broken plastic pieces on the screen plate 16 vibrate accordingly. During the vibration process, the dust falling on the broken plastic pieces continuously moves downward, and then passes through the filter holes and falls to the lower end of the inner cavity of the dust filter box 3 to be collected;

[0034] After running for a period of time, the number of broken plastic pieces accumulated on the screen plate 16 increases. At this time, the small vibration motor 17 stops running, and the first electric push cylinder 7 drives the screen plate 16 to move up to the discharge port through the output shaft and the connecting rod 14. Then, the second electric push cylinder 9 drives the push plate 8 to move along the upper end of the screen plate 16 toward the discharge port 12, thereby pushing the broken plastic pieces to the discharger 6 for discharge;

[0035] After the material is discharged, the second electric push cylinder 9 drives the material removal plate 8 to return to the push plate groove 13, the first electric push cylinder 7 drives the screen plate 16 to return to its original position, and the small vibration motor 17 restarts;

[0036] When a lot of dust is collected in the dust filter box, the dust inside can be cleaned by opening the cover plate 4.

[0037] Please refer to Figures 4 to 7 , the vibration dust filter unit also includes a first electric push cylinder 7, a connecting rod 14, a spring 15 and a small vibration motor 17;

The connecting rod 14 is fixedly connected to the upper end of the output shaft of the first electric push cylinder 7, and the upper end of the connecting rod 14 penetrates upward into the inner cavity of the dust filter box 3. The spring 15 is fixedly connected to the upper end of the connecting rod 14, and the sieve plate 16 is fixedly connected to the upper end of the spring 15. The sieve plate 16 slides up and down in the inner cavity of the dust filter box 3. Four small vibration motors 17 are respectively fixed at the four corners of the lower end of the sieve plate 16.

[0039] In this embodiment: a small vibration motor 17 and a spring 15 are used to make the screen plate 16 vibrate;

[0040] The first electric push cylinder 7 is used to drive the sieve plate 16 to rise to the discharge port 12 when discharging.

[0041] Please refer to Figure 7 A plurality of fine filter holes for filtering the falling dust are provided in the middle of the sieve plate 16 .

[0042] In this embodiment: the filter hole is used to intercept broken plastic pieces and allow dust to pass through.
