Description

Technical Field

[0001] This invention relates to the field of chain drive technology, specifically to a plastic film recycling chain. Background Technology

[0002] Existing plastic film recycling machines rely on belt drives and primarily operate through cast-iron pickup hooks riveted to the belts to collect and transport the recycled plastic film. The pickup hooks are located within the belts, penetrating 1-3 cm into the ground during operation, and multiple pickup belts work together. The belts themselves are circular with no detachable joints.

[0003] The existing technology has the following problems: Problem 1: When multiple pickup belts are used in conjunction on the same horizontal plane, if one or more pickup belts fail or break due to external force or external factors, all pickup belts and related accessories need to be disassembled and replaced, which is cumbersome and time-consuming.

[0004] Question 2: The cast pickup hook is installed on the belt by riveting. During the riveting process, holes need to be drilled in the belt, which reduces the overall strength of the belt. After a long time, it is easy for the belt to break and fail at the rivet hole.

[0005] Question 3: Traditional belt drives have high sliding resistance, the belt is prone to slippage, and the transmission efficiency is low. Utility Model Content

[0006] This invention discloses a plastic film recycling chain, which aims to solve problems one to three mentioned in the background section.

[0007] To achieve the above objectives, the technical solution of this invention is as follows: A plastic film recycling chain includes a roller chain body with a plurality of attached plate links evenly distributed on the roller chain body. Each attached plate link includes two oppositely arranged attached plate structures. Each attached plate structure includes a first connecting part for connecting with the roller chain body, an extension part integrally formed at the top of the first connecting part and extending into the inner side of the roller chain body, and a second connecting part integrally formed at the top of the extension part and extending vertically upward. The second connecting parts of the two attached plate structures are attached to each other and fixedly connected to form a picking structure for recycling plastic film.

[0008] Preferably, the roller chain body includes an inner link consisting of two inner chain plates, two sleeves, and two rollers; an outer link consisting of two outer chain plates and two pins; and an auxiliary plate link consisting of two auxiliary plate structures and two extended pins. The two inner chain plates are arranged opposite each other and connected by two sleeves, with both ends of the sleeves having an interference fit with the corresponding inner chain plate connection holes, and rollers having a clearance fit on the outside of the sleeves. The two outer chain plates are arranged opposite each other and connected by pins, with both ends of the two pins having an interference fit with the corresponding outer chain plate connection holes, and the pins passing through the inner holes of the sleeves of adjacent inner chain links and having a clearance fit with the sleeves. The first connecting part has two auxiliary plate connection holes, the two auxiliary plate structures are arranged opposite each other and connected by extended pins, with both ends of the two extended pins having an interference fit with the corresponding auxiliary plate connection holes, and the extended pins passing through the sleeves of adjacent inner chain links and having a clearance fit with the sleeves.

[0009] Preferably, the first connecting part and the extension part are bent to form an angle β, the extension part and the second connecting part are bent to form an angle α, and the second connecting part of the two attached plate structures is fixedly connected by pressing.

[0010] Preferably, both the first connecting part and the second connecting part are arranged vertically, and the angles α and β are in the range of 150-160°.

[0011] Preferably, the angles α and β are 155° or 156° respectively.

[0012] Preferably, the back side of the extension and the second connecting part is an inclined surface that slopes forward, the front side of the extension forms the working surface of the picking structure, and the angle γ between the working surface and the vertical plane is 3°.

[0013] Preferably, the thickness of the inner and outer chain plates is 3.2 mm, and the thickness of the auxiliary plate structure is 4 mm.

[0014] Preferably, the surface of the second connecting part is coated with a wear-resistant layer.

[0015] This novel plastic film recycling chain has the following beneficial effects: 1. This new type of machine solves the problems of high maintenance costs and long maintenance time of plastic film recycling machines, and realizes the technological upgrade of replacing belts with chains.

[0016] 2. This new design solves the problem of belts easily breaking after drilling holes to install pickup hooks; the pickup structure formed by the attached plate chain links can significantly extend the service life and improve the structural strength.

They are only for describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this invention.

[0022] The following embodiments can be understood as implementations of a local structure of the present invention individually, or as implementations of a larger range of structural features of the present invention through a combination of multiple embodiments.

[0023] Example 1: A plastic film recycling chain, such as Figure 1-5As shown, the system includes a roller chain body with several equally spaced auxiliary chain links. Each auxiliary chain link includes two opposing auxiliary structure 3s. Each auxiliary structure 3 includes a first connecting portion 34 for connecting to the roller chain body, an extension portion 31 integrally formed at the top of the first connecting portion 34 and extending towards the inner side of the roller chain body, and a second connecting portion 32 integrally formed at the top of the extension portion 31 and extending vertically upward. The second connecting portions 32 of the two auxiliary structure 3s are attached and fixedly connected to form a collection structure for recycling mulch film. During chain operation, the collection structure sequentially enters the soil to collect the mulch film from the soil surface.

[0024] Example 2: like Figure 1 , 4 As shown, the roller chain body includes an inner link consisting of two inner chain plates 1, two sleeves 6, and two rollers 5; an outer link consisting of two outer chain plates 2 and two pins 4; and an auxiliary link consisting of two auxiliary plate structures 3 and two extended pins 7. The two inner chain plates 1 are arranged opposite to each other and connected by two sleeves 6. The two ends of the sleeves 6 are respectively interference-fitted with the corresponding inner chain plate 1 connecting holes, and rollers 5 are respectively clearance-fitted onto the outside of the sleeves 6. The two outer chain plates 2 are arranged opposite to each other and connected by two sleeves 6. The two pins 4 are connected by an interference fit between their ends and the corresponding connecting holes of the outer chain plate 2. The pins 4 pass through the inner holes of the adjacent inner chain link sleeves 6 and are clearance-fitted with the sleeves 6. The first connection 34 is provided with two auxiliary plate connecting holes. The two auxiliary plate structures 3 are arranged opposite to each other and connected by extended pins 7. The two extended pins 7 are connected by an interference fit between their ends and the corresponding connecting holes of the auxiliary plates. The extended pins 7 pass through the sleeves 6 of the adjacent inner chain links and are clearance-fitted with the sleeves.

[0025] Example 3: like Figure 5 As shown, the first connecting part 34 and the extension part 31 are bent to form an angle β, and the extension part 31 and the second connecting part 32 are bent to form an angle α. The second connecting part 32 of the two attached plate structures is fixedly connected by pressing.

[0026] like Figure 5 As shown, the first connecting part 34 and the second connecting part 32 are both arranged vertically, and the angles α and β are in the range of 150-160°.

[0027] Example 4: Based on the above embodiments, as a preferred embodiment, the degree measures of angle α and angle β are 155° or 156°, respectively.

[0028] like Figure 1 , 2As shown, the back of the extension 31 and the second connecting part 32 is an inclined surface that slopes forward (in the direction of chain movement), and the front of the extension 31 forms the working surface 33 of the picking structure. The angle γ between the working surface 33 and the vertical plane (the plane perpendicular to the direction of chain movement) is 3°.

[0029] like Figure 1 , 4 As shown, the thickness of the inner and outer chain plates is 3.2 mm, the thickness of the attached plate structure is 4 mm, and the thickness of the two second connecting parts after pressing is 8 mm, which has higher structural strength.

[0030] like Figure 1-5 As shown, the surface of the second connecting part 32 is coated with a wear-resistant layer to improve the service life of the attached plate structure.

[0031] When this new type of chain is in use, as the chain rotates, the working surfaces of the auxiliary plate chain links are inserted into the soil in sequence to recover the mulch film on the soil surface. When individual auxiliary plate chain links fail, the links can be replaced without removing the entire chain, which greatly reduces maintenance costs and improves maintenance efficiency. As part of the roller chain body, the auxiliary plate chain links have higher structural strength and service life.
