Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste edge recycling technology, and in particular to a waste edge recycling device for the production of plastic hollow boards. Background Technology
[0002] Plastic hollow boards, as a lightweight, high-strength, and corrosion-resistant new type of environmentally friendly packaging material, are widely used in logistics, warehousing, advertising, and other fields. Their production process typically includes key steps such as raw material melting and extrusion, mold forming, cooling and shaping, and traction cutting. In the cutting stage, to ensure the dimensional accuracy and edge regularity of the finished product, the edges of the formed boards need to be trimmed, generating a large amount of plastic waste. As an inevitable byproduct of the production process, directly discarding these waste edges would not only result in a serious waste of plastic raw materials and increase production costs for enterprises, but also pollute the environment due to the non-biodegradable nature of plastic. Therefore, waste edge recycling has become an indispensable part of the plastic hollow board production process. Currently, the common recycling methods in the industry mostly rely on manual sorting and collection, a model that is not only inefficient but also difficult to match the pace of automated production lines.
[0003] In automated production systems for hollow plastic sheets, the automatic separation and recycling of waste edges from finished products is of significant practical importance. With the increasing intelligence of the manufacturing industry, the limitations of traditional manual recycling methods have become increasingly apparent: manual separation and recycling not only require substantial additional labor costs, but also face difficulties in precisely controlling the timing and speed of separation and recycling, potentially leading to waste edge accumulation on the production line, disrupting equipment operation, and even posing safety hazards. Furthermore, the instability of manual operation can cause secondary contact and friction between waste edges and finished products, potentially damaging the surface quality of the finished product and reducing the product qualification rate. Therefore, developing a device that can automatically and efficiently separate waste edges from finished products during production and directionally collect and recycle the waste edges can not only improve the continuity and automation of the production process and reduce reliance on manual labor, but also achieve efficient recycling of raw materials, meeting the industry's development needs for green production and cost reduction. Utility Model Content
[0004] The main purpose of this utility model is to provide a waste edge recycling device for the production of plastic hollow boards, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A waste edge recycling device for the production of plastic hollow boards includes two recycling containers. Each recycling container consists of a container body and a counterweight base. The counterweight base is fixedly installed at the lower end of the container body. Two supporting and buffering structures are symmetrically fixedly installed on the inner wall of the container body. Each supporting and buffering structure consists of a first L-shaped plate, a guide rod, a buffer spring, and an anti-detachment plate. The guide rod is fixedly installed at the upper end of the first L-shaped plate, the buffer spring is sleeved on the guide rod, and the anti-detachment plate is fixedly installed at the upper end of the guide rod. A guide structure is movably installed above the recycling containers and on the two supporting and buffering structures. The guide structure consists of an inclined plate, a second L-shaped plate, a rotating roller, and a support plate. There are two second L-shaped plates, symmetrically fixedly installed at the lower end of the inclined plate. Several rotating rollers are evenly rotated and installed inside the inclined plate. The support plate is fixedly installed at one end of the inclined plate. A separating component is fixedly installed on the support plate. The separating component consists of a separating triangular plate and an L-shaped connecting frame. The L-shaped connecting frame is fixedly installed at the rear end of the separating triangular plate.
[0006] Preferably, the two recycling containers are symmetrically arranged on both sides of the conveyor body, and a conveyor belt is installed on the conveyor body.
[0007] Preferably, the first L-shaped plate on the supporting buffer structure is fixedly installed on the inner wall of the container body by bolts.
[0008] Preferably, the inclined plate on the guide structure is located above the supporting buffer structure, and a through hole is provided on the lower side wall of the second L-shaped plate. The second L-shaped plate is movably sleeved on the guide rod on the supporting buffer structure through the through hole, and the second L-shaped plate is also located at the upper end of the buffer spring.
[0009] Preferably, the inclined plate on the guide structure has a plurality of roller grooves evenly distributed, the rotating roller is rotatably installed in the roller grooves, and the support plate is located above the conveyor body.
[0010] Preferably, the dividing triangle plate on the dividing assembly is located at the front end of the support plate, and the L-shaped connecting frame is fixedly installed on the upper end of the support plate by bolts.
[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a recycling container consisting of a container body and a counterweight base, a support and buffer structure consisting of a first L-shaped plate, guide rods, buffer springs, and anti-detachment plates, a guide structure consisting of an inclined plate, a second L-shaped plate, rotating rollers, and a support plate, a separation assembly consisting of a separating triangular plate and an L-shaped connecting frame, and a belt conveyor, the plastic hollow board cutting and conveying equipment is placed in front of the separation assembly during use. This aligns the separating triangular plate with the gap between the waste edge and the finished product. As the plastic hollow board cutting and conveying equipment conveys the cut waste edge and finished product backward, the separating triangular plate separates the waste edge from the finished product. The finished product falls onto the conveyor belt on the conveyor body and is then transported to the next processing stage. The waste edge, under the influence of inertia and gravity, falls onto the guide structure and eventually into the recycling container. This achieves automatic separation of waste edge and finished product, and directional recycling of waste edge, eliminating the need for manual sorting and collection. It effectively improves recycling efficiency, matches the rhythm of automated production lines, and reduces labor costs. At the same time, automatic separation and recycling can avoid secondary contact and friction between waste edges and finished products, reduce surface damage to finished products, and improve product qualification rate. The rotating rollers in the guide structure can reduce the frictional resistance when waste edges slide down, ensuring that waste edges fall smoothly into the recycling container and avoid accumulation. The support and buffer structure can provide elastic support to the guide structure through buffer springs. When waste edges fall onto the guide structure, the buffer springs can buffer the impact force, reduce device vibration, and improve structural stability. The counterweight base enhances the overall counterweight of the recycling container, preventing the container from tipping over due to the impact of falling waste edges, and further ensuring the stable operation of the device.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 , Figure 2 , Figure 3 As shown, a waste edge recycling device for the production of plastic hollow boards includes two recycling containers 1. Each recycling container 1 consists of a container body 7 and a counterweight base 8. The counterweight base 8 is fixedly installed at the lower end of the container body 7. Two support and buffer structures 2 are symmetrically fixedly installed on the inner wall of the container body 7. Each support and buffer structure 2 consists of a first L-shaped plate 9, a guide rod 10, a buffer spring 11, and an anti-detachment plate 12. The guide rod 10 is fixedly installed at the upper end of the first L-shaped plate 9, the buffer spring 11 is sleeved on the guide rod 10, and the anti-detachment plate 12 is fixedly installed at the upper end of the guide rod 10. A guide structure 3 is movably installed above the recycling container 1 and on the two support and buffer structures 2. The guide structure 3 consists of an inclined plate 13, a second L-shaped plate 14, and a rotating plate 15. The system consists of roller 16 and support plate 17. Two second L-shaped plates 14 are symmetrically and fixedly installed at the lower end of the inclined plate 13. Several rotating rollers 16 are uniformly installed within the inclined plate 13. The support plate 17 is fixedly installed at one end of the inclined plate 13. A separating component 4 is fixedly installed on the support plate 17. The separating component 4 consists of a separating triangular plate 18 and an L-shaped connecting frame 19. The L-shaped connecting frame 19 is fixedly installed at the rear end of the separating triangular plate 18. The system utilizes a recycling container 1 consisting of a container body 7 and a counterweight base 8, a support and buffer structure 2 consisting of a first L-shaped plate 9, guide rod 10, buffer spring 11, and anti-detachment plate 12, and a guide rod 16 consisting of an inclined plate 13, second L-shaped plate 14, rotating roller 16, and support plate 17. The separation component 4, consisting of a separating triangular plate 18 and an L-shaped connecting frame 19, and a belt conveyor, is used in conjunction with a plastic hollow board cutting and conveying equipment. During use, the plastic hollow board cutting and conveying equipment is placed in front of the separation component 4, aligning the separating triangular plate 18 with the gap between the waste edge and the finished product. As the plastic hollow board cutting and conveying equipment conveys the cut waste edge and finished product backward, the separating triangular plate 18 separates the waste edge from the finished product. The finished product falls onto the conveyor belt 6 on the main body of the conveyor 5 and is then conveyed to the next processing stage. The waste edge, under the influence of inertia and gravity, falls onto the guide structure 3 and eventually into the recycling container 1. This achieves automatic separation of the waste edge and the finished product, as well as directional recycling of the waste edge, without the need for manual intervention. The manual sorting and collection effectively improves recycling efficiency, matches the rhythm of automated production lines, and reduces labor costs. At the same time, automatic separation and recycling can avoid secondary contact and friction between waste edges and finished products, reduce surface damage to finished products, and improve product qualification rate. The rotating roller 16 in the guide structure 3 can reduce the frictional resistance when waste edges slide down, ensuring that waste edges fall smoothly into the recycling container 1 and avoid accumulation. The support and buffer structure 2 can provide elastic support to the guide structure 3 through the buffer spring 11. When waste edges fall onto the guide structure 3, the buffer spring 11 can buffer the impact force, reduce device vibration, and improve structural stability. The counterweight base 8 enhances the overall counterweight of the recycling container 1, preventing the container from tipping over due to the impact of falling waste edges, and further ensuring the stable operation of the device.
[0016] Specifically, two recycling containers 1 are symmetrically arranged on both sides of the conveyor body 5. A conveyor belt 6 is installed on the conveyor body 5. The first L-shaped plate 9 on the supporting buffer structure 2 is fixedly installed on the inner wall of the container body 7 by bolts. The inclined plate 13 on the guide structure 3 is located above the supporting buffer structure 2. A through hole is opened on the lower side wall of the second L-shaped plate 14. The second L-shaped plate 14 is movably sleeved on the guide rod 10 on the supporting buffer structure 2 through the through hole, and the second L-shaped plate 14 is also located on the buffer spring 11. At the end, a plurality of roller grooves 15 are evenly provided on the inclined plate 13 on the guide structure 3. The rotating roller 16 is rotatably installed in the roller groove 15. The support plate 17 is located above the conveyor body 5. The dividing triangle plate 18 on the dividing assembly 4 is located at the front end of the support plate 17. The L-shaped connecting frame 19 is fixedly installed on the upper end of the support plate 17 by bolts. When using the waste edge recycling device for the production of plastic hollow board, firstly, the entire device is installed in conjunction with the plastic hollow board cutting and conveying equipment and the conveyor body 5, so that the two recycling containers 1 are symmetrically arranged on the conveyor body. On both sides of body 5, the plastic hollow board cutting and conveying equipment is placed in front of the separating component 4. The position of the separating component 4 is adjusted to ensure that the separating triangle plate 18 is precisely aligned with the gap between the waste edge and the finished product of the cut plastic hollow board. When the plastic hollow board cutting and conveying equipment conveys the cut waste edge and the finished product backward, the separating triangle plate 18 will be passively inserted into the gap between the waste edge and the finished product to separate them. The finished product falls onto the conveyor belt 6 of the conveyor body 5 under the action of conveying force and is conveyed to the next processing stage, while the waste edge is subjected to inertia and gravity. The waste edge falls onto the inclined plate 13 of the guide structure 3. The rotating roller 16, which is installed in the roller groove 15 inside the inclined plate 13, reduces the resistance to the waste edge sliding down. As the waste edge slides down, it will generate friction with it and rotate in the roller groove 15, allowing the waste edge to slide down smoothly. At the same time, the impact force of the waste edge falling down acts on the inclined plate 13, which drives the second L-shaped plate 14 to press down on the buffer spring 11 along the guide rod 10. The buffer spring 11 deforms and generates elastic force to buffer the impact force. Finally, the waste edge falls down the inclined plate 13 into the container body 7 below, completing the automatic separation and directional recycling of the waste edge.
[0017] Furthermore, in the practical application of this waste edge recycling device for the production of hollow plastic sheets, special attention must be paid to controlling the distance between the hollow plastic sheet cutting and conveying equipment, the conveyor belt 6, and the separating component 4. The distance between them should not be too large. This is because if the distance is too large, the cut waste edge and the finished product are prone to positional deviation due to a lack of effective support and guidance during the process of being conveyed from the hollow plastic sheet cutting and conveying equipment to the area of the separating component 4 and the conveyor belt 6. This makes it difficult for the separating triangle plate 18 of the separating component 4 to accurately insert into the gap between the waste edge and the finished product, thus failing to achieve reliable separation between the two. At the same time, the finished product may also fail to fall accurately onto the conveyor belt due to deviation. 6. This affects subsequent conveying and processing procedures. In addition, in order to ensure that the scrap material can fall smoothly into the recycling container 1, the length of the recycling container 1, the inclined plate 13, and the rotating roller 16 can be increased forward according to the trajectory and range of the scrap material falling in actual production. By extending the size of the container body 7 along the scrap material falling direction, the receiving range of the recycling container 1, the inclined plate 13, and the rotating roller 16 for the scrap material is expanded, which effectively avoids the scrap material falling outside the recycling container 1 due to slight deviations in the scrap material falling trajectory or changes in the falling speed. This further improves the integrity and reliability of scrap material recycling and ensures that the device can complete the scrap material recycling operation stably and efficiently.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
