Description

Technical Field

[0001] The utility model relates to the field of plastic crushers, and more specifically, it relates to a plastic crusher facilitating feeding. Background Art

[0002] A plastic mill is a device used to crush various plastic and rubber materials, such as plastic profiles, pipes, rods, filaments, films, waste rubber products, etc. into pellets. The pellets can be directly used for extrusion as production raw materials. A crushing chamber is usually provided on the body of the plastic mill, and a crushing mechanism for crushing the raw materials of the pellets is arranged in the crushing chamber. To facilitate the addition of the raw materials of the pellets into the crushing cavity, a feeding box is usually installed on the upper part of the crushing chamber. By adding the raw materials to be crushed from the feeding port into the feeding box, it is convenient to perform the raw material adding operation for the plastic mill. However, when the plastic is crushed in the crusher, the plastic is likely to splash out of the feeding port, causing waste, and at the same time, it is likely to hit the operator, posing a safety hazard.

[0003] The utility model patent with the application number 202222064212.9 discloses a plastic mill, including a mill, a feeding port, and a discharging pipe. It also includes a door blocking mechanism, which consists of a strip-shaped plate, a bottom pipe, a rotating rod, a threaded head, a nut, a baffle plate, and an outer sealing plate. A feeding port for putting plastic into the mill for crushing is opened at the top box body of the mill, and a discharging pipe for discharging the crushed plastic extends from the side wall of the mill below the feeding port. The strip-shaped plate is fixedly installed at the inner wall of the top opening of the feeding port through bolts, and a bottom pipe that can penetrate the rotating rod is welded to the lower surface of the plate body of the strip-shaped plate away from the inner wall of the top opening of the feeding port. A threaded head that can be screwed with the nut is formed by turning on one end of the rotating rod extending out of the bottom pipe.

[0004] Through the above technical solution, although a door blocking mechanism can be set at the feeding port of the mill, and with the setting of the door blocking mechanism, the feeding port can be simply blocked when the mill is crushing plastic, thereby reducing the amount of plastic flying out of the feeding port. However, the blocking effect on the feeding port is not good, and it cannot prevent the plastic from flying out of the feeding port. At the same time, since the operator needs to be close to the feeding port when feeding, the possibility of the operator being hit by the flying crushed materials is greatly increased. It cannot automatically send the raw materials to be crushed into the feeding port to improve work efficiency and avoid the possibility of the operator being hit by the flying crushed materials when feeding close to the feeding port, increasing potential safety hazards and having low practicality. Summary of the Utility Model

[0016] Refer to Figures 1 to 3A further description is made of the embodiments of the present utility model.

[0017] A plastic crusher facilitating feeding, comprising a crusher 1. The crusher 1 includes a feeding box 2. The bottom of the feeding box 2 communicates with the crushing chamber on the crusher 1. A feeding port 201 is provided on the feeding box 2. A feeding device is provided on the crusher 1. The feeding device includes a feeding platform 3 corresponding to the feeding port 201, a conveyor 4 corresponding and cooperating with the feeding platform 3, an electric push rod 5 installed on the feeding platform 3, and a push plate 6 installed at the output end of the electric push rod 5.

[0018] One baffle 12 is installed on each side of the feeding platform 3. The two baffles 12 and the feeding platform 3 cooperate to form a feeding channel 1201 corresponding to the feeding port 201. The conveyor 4 is placed above the feeding channel 1201, and the output end of the conveyor 4 corresponds to the feeding channel 1201. The electric push rod 5 drives the push plate 6 to move in the feeding channel 1201, and when the push plate 6 moves to cooperate with the feeding port 201, it can be used to close the feeding port 201. A cover plate 7 for closing the feeding port 201 is hinged in the feeding box 2. A first spring 8 is installed on the push plate 6. A top rod 9 is hinged on the cover plate 7. A chamber 901 cooperating with the first spring 8 is opened in the top rod 9. The first spring 8 is fixed on the inner wall of the chamber 901.

[0019] Working principle: The electric push rod 5 works to drive the push plate 6 to move away from the feeding port 201 on the feeding platform 3, so that the top rod 9 moves away from the feeding box 2 to generate a pulling force on the cover plate 7, and further makes the cover plate 7 hinged with the top rod 9 and the feeding box 2 approach the feeding port 201 and gradually close the feeding port 201. The electric push rod 5 drives the push plate 6 to continue to move away from the feeding port 201 on the feeding platform 3. At this time, the first spring 8 in the chamber 901 of the top rod 9 elongates, and the first spring 8 generates a pulling force on the top rod 9, so that the top rod 9 further pulls the cover plate 7 close to the feeding port 201 until the feeding port 201 is closed, preventing the material particles from splashing out from the discharge port and hitting the operator during the process of the crusher 1 working to crush the raw material to be crushed into material particles, and improving the shielding effect.

[0020] The operator places the raw materials to be crushed on the conveyor belt of the conveyor 4. The conveyor 4 operates to convey the raw materials to be crushed to the feeding platform 3 and let them fall into the feeding channel 1201. The electric push rod 5 operates to drive the push plate 6 to move in the feeding channel 1201 towards the feeding port 201. The baffle 12 on the feeding platform 3 restricts the raw materials to be crushed within the feeding channel 1201, preventing the position of the raw materials to be crushed from shifting when the push plate 6 pushes them into the feeding port 201 and affecting the entry of the raw materials to be crushed into the feeding port 201. During the process of the push plate 6 pushing the raw materials to be crushed into the feeding port 201, the first spring 8 in the extended state gradually returns to its original state and enters the chamber 901 of the ejector rod 9. The push plate 6 continues to move towards the feeding port 201. The push plate 6 generates a thrust on the ejector rod 9, so that the ejector rod 9 generates a thrust on the cover plate 7 to move the cover plate 7 away from the feeding port 201 and thus open the feeding port 201. At this time, the push plate 6 gradually approaches the feeding port 201 and pushes the raw materials to be crushed to enter the feeding box 2 from the feeding port 201 and fall into the crushing chamber on the crusher 1 for crushing, avoiding the safety hazard of the operator approaching the feeding port 201 to put the raw materials to be crushed into the feeding box 2. At the same time, the working efficiency is improved, and the practicability is strong. Moreover, the push plate 6 continues to move until it closes the feeding port 201, further improving the shielding effect and preventing the crushed particles from splashing out of the feeding port 201 and hitting the operator when the crusher 1 crushes the raw materials to be crushed into particles, eliminating the safety hazard. Finally, it is realized that the utility model can not only automatically send the raw materials to be crushed into the feeding port 201 to improve the working efficiency, but also avoid the possibility of the operator being hit by the splashed crushed materials when feeding near the feeding port 201. At the same time, the shielding effect at the feeding port 201 is improved, preventing the crushed materials from splashing out of the feeding port 201 and hitting the operator, eliminating the safety hazard, and enhancing the practicability.

[0021] A receiving plate 10 corresponding to the feeding port 201 is hinged in the feeding box 2. The receiving plate 10 is inclined towards the bottom of the feeding box 2. A second spring 11 is arranged on the receiving plate 10. The two ends of the second spring 11 are respectively installed on the receiving plate 10 and the inner wall of the feeding box 2. After the raw materials to be crushed enter the feeding box 2, they fall on the receiving plate 10. As the raw materials to be crushed falling on the receiving plate 10 continuously increase, the pressure on the receiving plate 10 continuously increases, so that the second spring 11 extends, and the receiving plate 10 continuously approaches the bottom of the feeding box 2, and then the raw materials to be crushed on the receiving plate 10 fall into the crushing chamber on the crusher 1 for crushing, avoiding the blockage problem caused by too much raw materials entering the feeding box 2, further enhancing the practicability. At the same time, the setting of the receiving plate 10 can block the particles in the crushing chamber on the crusher 1 from splashing towards the feeding port 201, further improving the shielding effect and eliminating the safety hazard.

[0022] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model shall be included within the protection scope of the present utility model.
