[0005] Preferably, the crushing bin side is provided with worm gear reducer, and the worm gear reducer side is fixedly provided with motor;The motor, worm gear reducer can drive one side of the crushing counter-roller to rotate.

[0006] Preferably, the power output shaft end of the worm gear reducer is transmissionally connected between the crushing counter-roller, and the power output shaft end of the motor is transmissionally connected between the power input shaft end of the worm gear reducer.

[0007] Preferably, the crushing counter-roller one end is fixedly provided with gear, and the gear is meshed with each other, the gear can drive two crushing counter-rollers to be linked together, so that one side crushing counter-roller can drive the crushing counter-roller of the other side to rotate when rotating;And it is relatively rotating, so that the crushing work of plastic can be carried out using two relatively rotating crushing counter-rollers.

[0008] Preferably, pulleys are fixedly installed at one end of the crushing roller and the rotating rod on one side, and a transmission belt is sleeved between the pulleys. The crushing roller and the rotating rod can be linked together through the pulleys and the transmission belt. In this way, when the crushing roller rotates, it can drive the rotating rod to rotate as well. The rotation of the rotating rod in this device only plays a basic feeding role and the required torque is limited. Therefore, the transmission belt and pulley are sufficient.

When the waste material rotates to the lower half of the feeding bin, it will automatically fall into the crushing bin under the action of gravity and come into contact with the continuously rotating crushing roller. The plastic can be crushed by the relatively rotating crushing roller. Even if the plastic breaks suddenly during crushing and splashes, the presence of the partition plate will prevent the splashed plastic from flying out of the feeding port and causing injury, thus improving the safety of the device during use.

[0012] 2. When this utility model is in use, the crushing roller, rotating rod, and partition are fully linked by belts and pulleys, so no other control and power mechanisms are required, which makes it easy to operate and use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a plastic recycling device, including a crushing chamber 1, a feeding chamber 2 fixedly installed at the upper end of the crushing chamber 1, crushing rollers 13 movably installed on both sides of the inside of the crushing chamber 1 via bearings, a feeding mechanism for controlling feeding is provided at the upper end of the feeding chamber 2, the feeding mechanism includes a rotating rod 3, a partition 4, a cavity 5, and a limiting plate 6, a transmission rod movably installed in the middle of the inner side of the feeding chamber 2 via bearings, a plurality of partitions 4 are uniformly fixedly installed on the outer surface of the transmission rod, cavities 5 are provided between the partitions 4, and limiting plates 6 are provided on both sides of the partitions 4 inside the crushing chamber 1.

[0019] A worm gear reducer 7 is provided on one side of the crushing chamber 1, and an electric motor 8 is fixedly provided on one side of the worm gear reducer 7; the electric motor 8 and the worm gear reducer 7 can drive the crushing rollers 13 on one side to rotate.

[0020] The power output shaft of the worm gear reducer 7 is connected to the crushing roller 13, and the power output shaft of the motor 8 is connected to the power input shaft of the worm gear reducer 7.

[0021] A gear 9 is fixedly provided at one end of the crushing roller 13. The gears 9 mesh with each other and can link the two crushing rollers 13 together, so that when one crushing roller 13 rotates, it can drive the other crushing roller 13 to rotate in a coordinated manner; and they rotate relative to each other. In this way, the crushing of plastic can be carried out by using the two relatively rotating crushing rollers 13.

[0022] One end of the crushing roller 13 and the rotating rod 3 are both fixedly provided with pulleys 10. A transmission belt 11 is sleeved between the pulleys 10. The crushing roller 13 and the rotating rod 3 can be linked together through the pulleys 10 and the transmission belt 11. In this way, when the crushing roller 13 rotates, it can drive the rotating rod 3 to rotate together. The rotation of the rotating rod 3 in this device only plays a basic feeding role and the required torque is limited. Therefore, the transmission belt 11 and pulleys 10 are sufficient for transmission. Of course, the transmission belt 11 and pulleys 10 in this application can also be replaced by sprockets or transmission chains as needed.

[0023] Guide plates 12 are fixedly installed on both sides of the inside of the crushing chamber 1. The plastic to be crushed can be guided to the crushing rollers 13 through the guide plates 12.

[0024] Working principle: This device requires a feeding device, such as a conveyor belt, to transport the plastic to be crushed to the feed inlet. Each time material is fed, only the cavity 5 between the partitions 4 needs to be filled, not completely. Filling to two-thirds of the depth is optimal. Then, as the motor 8 drives the crushing roller to rotate, it drives the transmission rod and partitions 4 to rotate continuously. This causes the plastic waste in the cavity 5 between the partitions 4 to rotate. When the waste rotates to the lower half of the feed bin 2, it will automatically fall into the crushing bin 1 under the action of gravity and come into contact with the continuously rotating crushing roller. The plastic can be crushed by the relatively rotating crushing roller. Even if the plastic is crushed and some parts of the plastic suddenly break and splash, due to the presence of the partitions 4, it is difficult for the splashed plastic to fly out of the feed inlet and cause injury, thus improving the safety of the device during use.

[0025] Furthermore, when this device is in use, the crushing roller, rotating rod 3, and partition 4 are fully linked by belt and pulley 10, so no other control and power mechanism is required, which makes it easy to operate and use.

[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
