Description

Technical Field

[0001] This utility model relates to crushers, specifically an environmentally friendly recycled material crusher. Background Technology

[0002] Currently, many scraps cut off during the use or production of existing films are simply thrown away as garbage. However, films are mostly made of plastic, which is not environmentally friendly and is quite wasteful. Therefore, in order to protect the environment, existing technologies usually recycle them and crush them with a crusher to reprocess them into new films for use. Scraps cut off during film production are also crushed by a crusher and fed into the film raw materials for film production.

[0003] Existing crushers often fail to completely break down recycled films or scraps due to the films' good plasticity, flexibility, and tendency to stretch. This results in poor crushing efficiency and reduced crushing effectiveness. Furthermore, long strips of film can become entangled on the rotating shaft, hindering normal operation and requiring manual intervention, further reducing efficiency. Therefore, an environmentally friendly recycled material crusher is proposed. Utility Model Content

[0004] The purpose of this invention is to propose an environmentally friendly recycled material crusher to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly recycling crusher, characterized by including a crushing chamber, a feeding chamber connected to the crushing chamber, a collection chamber located below the crushing chamber for collecting crushed materials, and a dual-shaft differential shearing mechanism installed within the crushing chamber. The dual-shaft differential shearing mechanism includes a main shaft and a secondary shaft installed within the crushing chamber, a main motor installed on the crushing chamber for driving the main shaft to rotate, a secondary motor for driving the secondary shaft to rotate, and shearing blades installed on the main shaft and the secondary shaft and arranged in an alternating manner.

[0006] A further preferred embodiment includes a comb plate that can be detachably installed on the side wall of the crushing chamber to prevent long strips of material from getting tangled around the main shaft or the auxiliary shaft.

[0007] In a further preferred embodiment, the comb plate is provided with a plurality of comb teeth arranged alternately with the shearing blade, and the ends of the comb teeth are provided with hooks, the hooks being provided with cutting edges.

[0008] In a further preferred embodiment, the bottom of the feeding hopper is provided with a guide plate that guides the material, and a material outlet is provided between the two guide plates.

[0009] The beneficial effects of this utility model are as follows: By setting up a dual-shaft differential shearing mechanism, when crushing materials, the main shaft and the secondary shaft rotate at different speeds. The shearing blades on the main shaft and the secondary shaft are staggered and rotate in opposite directions, forming a differential shearing force, which enhances the crushing effect on materials.

[0010] A detachable comb plate is installed on the side wall of the crushing chamber. The detachable design facilitates cleaning and maintenance. Several comb teeth are set on the comb plate, which are staggered with the shearing blades. Hooks are set at the ends of the comb teeth, and the hooks are equipped with cutting edges. A gap is left between the hooks and the main shaft and the auxiliary shaft to avoid friction. The hooks hook off the long strips of material wrapped around the main shaft or auxiliary shaft, and the material is cut off by the cutting edges during the contact process, thus preventing the material from wrapping around the main shaft or auxiliary shaft.

[0016] The following description, in conjunction with the accompanying drawings, further illustrates the environmentally friendly recycled material crusher of this utility model.

[0017] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, 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.

[0019] See Figures 1-4 As shown, an environmentally friendly recycling crusher is characterized by including a crushing chamber 1, a feeding chamber 2 connected to the crushing chamber 1, a collection chamber 3 located below the crushing chamber 1 for collecting crushed materials, and a dual-shaft differential shearing mechanism disposed in the crushing chamber 1. The dual-shaft differential shearing mechanism includes a main shaft 4, a secondary shaft 41 disposed in the crushing chamber 1, a main motor 42 mounted on the crushing chamber 1 for driving the main shaft 4 to rotate, a secondary motor 43 for driving the secondary shaft 41 to rotate, and shearing blades 44 mounted on the main shaft 4 and the secondary shaft 41 and arranged in an alternating manner.

[0020] With the dual-shaft differential shearing mechanism, when crushing materials, the main shaft 4 and the secondary shaft 41 rotate at different speeds. The shearing blades 44 on the main shaft 4 and the secondary shaft 41 are staggered and rotate in opposite directions, forming a differential shearing force and enhancing the crushing effect on materials.

[0021] The feeding hopper 2 is used for feeding materials. Materials can be collected manually and then fed in, or materials can be drawn into the material hopper by vacuum pumping and then fall into the crushing hopper 1 for crushing.

[0022] The collection bin 3 is used to collect the crushed material. It can be directly connected to the subsequent process and supplied to the subsequent process. Alternatively, a pull-out drawer can be installed at the bottom of the collection bin 3 so that the drawer can be pulled out to retrieve the material.

[0023] In one embodiment, a comb plate 5 is also included that is detachably installed on the side wall of the crushing chamber to prevent long strips of material from getting tangled around the main shaft 4 or the secondary shaft 41.

[0024] The comb plate 5 is provided with a plurality of comb teeth 51 arranged alternately with the shearing blade 44, and the end of the comb teeth 51 is provided with a hook 52, and the hook 52 is provided with a cutting edge.

[0025] A detachable comb plate 5 is installed on the side wall of the crushing chamber. The detachability is for easy cleaning and maintenance. The comb plate 5 can be fixed to the side wall of the crushing chamber by screws, etc. A limiting platform can be set on the side wall of the crushing chamber. After the comb plate 5 is installed on the limiting platform, it is locked with screws. Several comb teeth 51 are set on the comb plate 5. The comb teeth 51 are staggered with the shearing blade 44 and hooks 52 are set at the ends of the comb teeth 51. The hooks 52 are provided with cutting edges. There is a gap between the hooks 52 and the main shaft 4 and the auxiliary shaft 41 to avoid friction. The long strips of material wrapped around the main shaft 4 or the auxiliary shaft 41 are hooked off by the hooks 52 and cut by the cutting edges during the contact process, so as to prevent the material from wrapping around the main shaft 4 or the auxiliary shaft 41.

[0026] In one embodiment, the bottom of the feed hopper 2 is provided with a guide plate 21 that guides the material, and a material outlet 22 is provided between the two guide plates 21. The guide plate 21 guides the material to move to the material outlet 22 and at the same time prevents the material from remaining in the feed hopper 2. The material outlet 22 is located between the main shaft 4 and the secondary shaft 41.

[0027] In use, the operator puts the collected waste material into the feeding bin 2. The material fed into the feeding bin 2 falls into the crushing bin 1 along the guide plate 21 and guide outlet at the bottom of the feeding bin 2 and is located between the main shaft 4 and the auxiliary shaft 41. The main motor 42 and the auxiliary motor 43 drive the main shaft 4 and the auxiliary shaft 41 to rotate respectively. The main shaft 4 and the auxiliary shaft 41 rotate in opposite directions and have a speed difference setting. The material crushed by the shearing blades 44 on the main shaft 4 and the auxiliary shaft 41 falls into the collection bin 3. When material is wrapped around the main shaft 4 or the auxiliary shaft 41, it comes into contact with the hook part 52 of the comb tooth 51 during the rotation of the main shaft 4 and the auxiliary shaft 41. While being hooked off by the hook part 52, the material is cut by the cutting edge of the hook part 52, thus preventing the material from wrapping around the main shaft 4 or the auxiliary shaft 41.

[0028] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
