Description

Technical Field

[0001] This utility model relates to the field of shredder technology, specifically a shredder pressing device. Background Technology

[0002] In plastic recycling and crushing operations, shredders play a crucial role in breaking large pieces of plastic into suitable sizes. However, currently widely used shredders often face problems such as material slippage and uneven feeding when processing plastic materials. Because plastic itself has a certain degree of smoothness, especially some processed waste plastics, it is difficult to be stably clamped and conveyed to the shredding blades after entering the shredder's feed inlet. Irregular feeding also causes the shredding blades to bear uneven loads. Over long-term use, this can easily lead to accelerated blade wear and even equipment failure. Therefore, it is necessary to compact the plastic material entering the feed inlet.

[0003] A shredder pressing device disclosed in existing patent publication number CN221734387U includes a protective shell, a shredder installed inside the protective shell, and a collecting mechanism welded to the bottom of the protective shell. The collecting mechanism is used to collect the shredded debris. The collecting mechanism includes a protective component and a storage component. The protective component is used to protect the storage component, and the storage component is used to store the debris. The protective component is located at the bottom of the protective shell, and the storage component is located inside the protective component. The pressing plate can squeeze and fix the waste, which facilitates effective shredding by the shredder.

[0004] The aforementioned device can compress materials before tearing, but using a pressure plate to compress from the top affects the feeding of the shredder. To address these issues, a shredder pressing device is proposed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] 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.

[0024] Please see Figures 1-4 In this embodiment, a shredder pressing device includes a feeding box 1 and a pressing mechanism 2 installed on the feeding box 1; the top of the feeding box 1 is connected to two sets of baffle plates 3, and an auxiliary feeding mechanism 4 is provided between the two sets of baffle plates 3; an adjusting mechanism 5 for adjusting the position of the auxiliary feeding mechanism 4 is installed on one side of the feeding box 1.

[0025] The material first enters the feed box 1. The two sets of baffles 3 at the top of the feed box 1 play a preliminary limiting role on the material, preventing the material from overflowing from both sides during the conveying process and ensuring that the material can enter the device along the preset path.

[0026] The auxiliary feeding mechanism 4 includes a guide plate 41 and a rotating block 42 fixedly connected to one side of the guide plate 41. The top of the feed box 1 is connected to a rotating seat 43 rotatably connected to the rotating block 42. A spring rod 44 is rotatably connected to one side of the guide plate 41 extending into the feed box 1. The spring rod 44 is installed on one side of the inner wall of the feed box 1. The spring rod 44 provides buffering and restoring force for the rotation of the guide plate 41, providing a buffering effect and reducing damage from excessively hard materials or sudden impacts.

[0027] The adjustment mechanism 5 includes an electric telescopic rod 51 and a connecting rod 52 rotatably connected to the top of the electric telescopic rod 51. The top of the connecting rod 52 is rotatably connected to a buffer rod 53, and the buffer rod 53 is connected to one side of the guide plate 41. The height of the connecting rod 52 can be adjusted by the electric telescopic rod 51, and the connecting rod 52 can pull the buffer rod 53, thereby adjusting the angle of the guide plate 41. The repeated angle changes of the two sets of guide plates 41 can also shake the material into the pressing area.

[0028] Please see Figure 2 The pressing mechanism 2 includes two sets of pressing rollers 21 rotatably installed in the feed box 1. A drive source 22 for driving one set of pressing rollers 21 to rotate is installed on the outside of the feed box 1. A transmission box 23 for driving one set of pressing rollers 21 to drive the other set of pressing rollers 21 is provided on the side of the feed box 1 away from the drive source 22. The transmission box 23 can be an existing transmission component, such as two sets of meshing gears, with the gear shaft ends connected to the shaft ends of the pressing rollers 21.

[0029] Specifically, the drive source 22 drives one set of pressure rollers 21 to rotate. Through the transmission action of the transmission box 23, the other set of pressure rollers 21 rotates in the opposite direction to squeeze and compact the material so that the subsequent shredding process can proceed smoothly.

[0030] Furthermore, the surface of the pressure roller 21 is provided with pressure protrusions; specifically, the pressure protrusions on the surfaces of the two sets of pressure rollers 21 enhance the friction with the material.

[0031] Please see Figure 3 and Figure 4 The spring rod 44 includes a sleeve rod 441 and a slide rod 442 that slides with the inner wall of the sleeve rod 441. The sleeve rod 441 is rotatably connected to one side of the inner wall of the feed box 1, and the slide rod 442 is rotatably connected to one side of the guide plate 41. The slide rod 442 extends into the sleeve rod 441 and connects to a first spring 443. When the slide rod 442 is compressed, it can slide within the sleeve rod 441 and compress the first spring 443.

[0032] Please see Figure 3 and Figure 4The buffer rod 53 includes a square rod 531 and a connecting rod 532 that slides with the inner wall of the square rod 531. The square rod 531 is rotatably connected to the connecting rod 52. The connecting rod 532 is fixedly connected to one side of the guide plate 41. The connecting rod 532 extends to one end of the inner cavity of the square rod 531 and is connected to a second spring 533. The first spring 443 and the second spring 533 provide a buffering effect to reduce damage to the device caused by excessively hard materials or sudden impacts.

[0033] Please see Figure 1 The electric telescopic rod 51 is installed on one side of the outer wall of the feed box 1.

[0034] Furthermore, the bottom of the feed box 1 is provided with a mating edge, and the mating edge is provided with mounting holes; the mating edge and mounting holes facilitate the docking and installation of the device with the shredder body, improving the ease of equipment assembly.

[0035] The working principle of this utility model is as follows: The material first enters the feeding box 1. The two sets of baffles 3 at the top of the feeding box 1 play a preliminary limiting role for the material, preventing the material from overflowing from both sides during the conveying process and ensuring that the material can enter the device along the preset path. The spring rod 44 provides buffering and restoring force for the rotation of the guide plate 41, providing a buffering effect and reducing damage from excessively hard materials or sudden impacts. The height of the connecting rod 52 can be adjusted by the electric telescopic rod 51. The connecting rod 52 can pull the buffer rod 53, thereby adjusting the angle of the guide plate 41. The repeated angle changes of the two sets of guide plates 41 can also shake the material into the pressing area. The drive source 22 drives one set of pressing rollers 21 to rotate. Through the transmission action of the transmission box 23, the other set of pressing rollers 21 rotates in the opposite direction, squeezing and compacting the material to facilitate the smooth progress of the subsequent shredding process.
