Description

Technical Field

[0001] The utility model relates to the field of PVC flooring, and in particular to an online crushing and recycling device for PVC flooring scraps. Background Art

[0002] In the flooring industry, there are two main methods for handling PVC scraps. The first method is to cut the scraps online during extrusion production. In this way, the staff at the material collection will pack and arrange the scraps neatly, and then transport them to the crushing process for crushing. The other method is not to cut the scraps during extrusion production, but to wait until the sawing process to saw them. These scraps are also collected and neatly stacked by the material collection staff, and then transported to the crushing process for crushing.

[0003] It is worth noting that the main raw materials of PVC flooring are PVC and stone powder. As a thermoplastic material, PVC is soft when hot and hard when cold. At present, when the two schemes are implemented, the edge materials have been cooled. The hardness of the edge materials after cooling increases, making the crushing process relatively difficult, which not only increases the labor intensity of personnel and energy consumption, but also generates more noise.

[0004] In summary, both current solutions have certain shortcomings in processing PVC scraps. Therefore, for the flooring industry, seeking a more efficient and environmentally friendly treatment method is an urgent problem to be solved. Utility Model Content

[0005] In view of this, the utility model provides an online crushing and recycling device for PVC floor scraps. A guide roller is arranged below the scrap cutting knife. The cut scraps are run in the opposite direction of the floor conveying direction after passing through the guide rollers, and are heated and softened by the heat of the roller surface after passing through a five-roller conveying assembly. The hardness of the softened scraps is reduced, and the energy consumption required for crushing and the noise generated are both smaller, so that the scraps are easier to be crushed by the crusher, so as to complete the online crushing and recycling of PVC floor scraps.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] A PVC floor scrap online crushing and recovery device comprises a five-roller conveying assembly for conveying the PVC floor, a scrap cutting knife for cutting the PVC floor, and a guide roller matched with the scrap cutting knife, wherein the scrap cutting knife is located above the PVC floor, and the guide roller is located below the PVC floor.

[0008] A guide roller is set below the edge material cutting knife. The cut edge material runs in the opposite direction of the floor conveying direction after passing through the guide roller. At this time, the edge material is hot and has a certain toughness and is not easy to break. The circular motion trajectory and the principle of opposite motion directions of the upper and lower parts make the edge material have the power to run in the opposite direction and move to the five-roller conveyor assembly again. After passing through the five-roller conveyor assembly, the edge material is heated and softened by the heat of the roller surface. The hardness of the softened edge material is reduced, and the energy consumption and noise generated by crushing are both small, making the edge material easier to be crushed by the crusher to complete the online crushing and recycling of PVC floor edge materials. The guide roller is a rubber roller with a diameter of 10-20cm. A rubber roller with a hardness of 50-70 degrees can be used, so that the roller surface of the guide roller has a certain strength and is not easily scratched by the edge material.

[0009] Preferably, the five-roller conveying assembly includes a first roller and a fifth roller located above the PVC floor, and a second roller, a third roller and a fourth roller located below the PVC floor. A gap is left between the first roller and the second roller, and the PVC floor is conveyed through the gap between the first roller and the second roller. A gap is left between the fourth roller and the fifth roller, and the PVC floor is conveyed through the gap between the fourth roller and the fifth roller. The third roller is located between the second roller and the fourth roller, and lifts the PVC floor upward.

[0010] First, the gap between the first and second rollers, and the gap between the fourth and fifth rollers are used to convey the PVC floor, achieving fast and accurate conveying, effectively avoiding the problems of material jamming and friction that may occur in traditional conveying methods, and improving the stability and efficiency of conveying. Secondly, the three-roller design cleverly lifts the PVC floor upwards, ensuring the flatness and direction accuracy of the floor during the conveying process, and ensuring the smooth conveying of the PVC floor.

[0011] Preferably, it also includes a conforming roller that cooperates with the five-roller conveying assembly and is used to convey the edge material.

[0012] The contact roller that cooperates with the five-roller conveyor assembly is an innovative highlight. It can cooperate with the five-roller conveyor assembly to ensure the accurate conveying of the edge material, and it also has an adaptive function, which can automatically adjust the conveying angle and pressure according to the edge materials of different shapes and sizes, ensuring that the edge materials and the PVC floor are synchronously and accurately conveyed to the designated position. In addition, the contact roller is a high-temperature resistant rubber roller with a diameter of 10cm and a soft roller with a hardness of 30-40 degrees to adapt to the characteristics of the variable thickness of the edge materials. The roller surface has low hardness and good elasticity, which is beneficial to the contact of uneven thickness edge materials without breaking the edge materials.

[0013] Preferably, there are multiple adhesive rollers, one of the multiple adhesive rollers is close to the four-roller and leaves a gap for the edge material to be transmitted, two of the multiple adhesive rollers are close to the three-roller and leave a gap for the edge material to be transmitted, and two of the multiple adhesive rollers are close to the two-roller and leave a gap for the edge material to be transmitted.

[0014] The multiple compliant roller design further enhances the flexibility and efficiency of conveying the edge material. By arranging multiple compliant rollers on the conveying path, precise adjustment can be made for edge materials of different sizes and shapes, ensuring that the edge materials can be synchronously and accurately conveyed to the designated position with the PVC floor.

[0015] Preferably, the edge material cutting knife is located next to the fifth roller, the guide roller is located next to the fourth roller, and a power roller is arranged between the guide roller and the fourth roller.

[0016] The design of the edge material cutting knife located next to the fifth roller and the guide roller next to the fourth roller further enhances the guidance and stability during the conveying process. The power roller between the guide roller and the fourth roller provides continuous and stable pressure for the PVC floor and edge materials, ensuring the flatness and consistency of the material during the conveying process. This design can still maintain excellent performance and stability in the face of mass production or high-intensity workloads, and is an indispensable part of modern production lines.

[0017] Preferably, there are multiple powered rollers, and the multiple powered rollers are evenly distributed.

[0018] The even distribution of multiple power rollers provides more even and stable force support for material transmission. Compared with the traditional single power roller, multiple power rollers can more effectively disperse the load, reduce equipment fatigue and wear, and extend the service life of the equipment. At the same time, the evenly distributed power rollers can also be intelligently adjusted according to materials of different sizes and shapes, providing just the right support force to ensure smooth material transmission and reduce stagnation and friction.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model discloses an online crushing and recycling device for PVC floor scraps, wherein a guide roller is arranged below a scrap cutting knife, and the cut scraps are moved in the opposite direction to the conveying direction of the floor after passing through the guide roller. At this time, the scraps are hot materials, have certain toughness and are not easy to break. The circular motion track and the principle of opposite upper and lower motion directions are utilized to enable the scraps to have the power to move in the opposite direction and move to the five-roller conveying assembly again. After passing through the five-roller conveying assembly, the scraps are heated and softened by the heat of the roller surface, and the hardness of the softened scraps is reduced, and the energy consumption required for crushing and the noise generated are both small, so that the scraps are easier to be crushed by the crusher, so as to complete the online crushing and recycling of PVC floor scraps.

[0027] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0028] The present embodiment provides an online crushing and recovery device for PVC floor scraps, including a five-roller 15 conveying assembly 10 for conveying PVC floors, a scrap cutting knife 20 for cutting PVC floors, and a guide roller 30 cooperating with the scrap cutting knife 20. The scrap cutting knife 20 is located above the PVC floor, and the guide roller 30 is located below the PVC floor.

[0029] A guide roller 30 is arranged below the edge material cutting knife 20. The cut edge material is moved in the opposite direction of the floor conveying direction after passing through the guide roller 30. At this time, the edge material is hot material and has a certain toughness and is not easy to break. The edge material has the power to move in the opposite direction by using the circular motion trajectory and the principle that the upper and lower motion directions are opposite, so that the edge material has the power to move in the opposite direction and moves to the five-roller 15 conveying assembly 10 again. After the edge material passes through the five-roller 15 conveying assembly 10, it is heated and softened by the heat of the roller surface. The hardness of the softened edge material is reduced, and the energy consumption and noise generated by crushing are both small, making the edge material easier to be crushed by the crusher to complete the online crushing and recycling of the PVC floor edge material. The guide roller 30 can be a rubber roller with a hardness of 50-70 degrees, so that the roller surface of the guide roller 30 has a certain strength and is not easily scratched by the edge material.

[0030] In this embodiment, the five-roller 15 conveying assembly 10 includes a first roller 11 and a fifth roller 15 located above the PVC floor, and a second roller 12, a third roller 13 and a fourth roller 14 located below the PVC floor. A gap is left between the first roller 11 and the second roller 12, and the PVC floor is conveyed through the gap between the first roller 11 and the second roller 12. A gap is left between the fourth roller 14 and the fifth roller 15, and the PVC floor is conveyed through the gap between the fourth roller 14 and the fifth roller 15. The third roller 13 is located between the second roller 12 and the fourth roller 14, and lifts the PVC floor upward.

[0031] First, the gap between the first roller 11 and the second roller 12, and the gap between the fourth roller 14 and the fifth roller 15 are used to convey the PVC floor, so as to achieve fast and accurate conveying, effectively avoiding the problems of material jamming and friction that may occur in the traditional conveying method, and improving the stability and efficiency of conveying. Secondly, the design of the third roller 13 cleverly lifts the PVC floor upwards, ensuring the flatness and direction accuracy of the floor during the conveying process, and ensuring the smooth conveying of the PVC floor.

[0032] In this embodiment, a conforming roller 40 is also included which cooperates with the five-roller 15 conveying assembly 10 and is used to convey the edge material.

[0033] The contact roller 40 that cooperates with the five-roller 15 conveying assembly 10 is an innovative highlight. It can cooperate with the five-roller 15 conveying assembly 10 to ensure the accurate conveying of the edge material, and it also has an adaptive function, which can automatically adjust the conveying angle and pressure according to the edge materials of different shapes and sizes, ensuring that the edge materials and the PVC floor are synchronously and accurately conveyed to the designated position. In addition, the contact roller 40 uses a soft roller with a hardness of 30-40 degrees to adapt to the characteristics of the variable thickness of the edge materials. The roller surface has low hardness and good elasticity, which is beneficial to the contact of uneven thickness edge materials without crushing the edge materials.

[0035] The design of multiple conforming rollers 40 further enhances the flexibility and efficiency of conveying the edge material. By arranging multiple conforming rollers 40 on the conveying path, precise adjustment can be made for edge materials of different sizes and shapes, ensuring that the edge materials can be synchronously and accurately conveyed to the designated position with the PVC floor.

[0036] In this embodiment, the edge material cutting knife 20 is located next to the fifth roller 15 , the guide roller 30 is located next to the fourth roller 14 , and a power roller 50 is provided between the guide roller 30 and the fourth roller 14 .

[0037] The design of the edge material cutting knife 20 being located next to the fifth roller 15 and the guide roller 30 being located next to the fourth roller 14 further enhances the guidance and stability during the conveying process. The power roller 50 between the guide roller 30 and the fourth roller 14 provides continuous and stable pressure for the PVC floor and edge materials, ensuring the flatness and consistency of the materials during the conveying process. This design can still maintain excellent performance and stability in the face of mass production or high-intensity workloads, and is an indispensable part of modern production lines.

[0038] In this embodiment, there are multiple power rollers 50, and the multiple power rollers 50 are evenly distributed.

[0039] The uniform distribution of multiple power rollers 50 provides more uniform and stable force support for material transmission. Compared with the traditional single power roller 50, multiple power rollers 50 can more effectively disperse the load, reduce equipment fatigue and wear, and extend the service life of the equipment. At the same time, the uniformly distributed power rollers 50 can also be intelligently adjusted according to materials of different sizes and shapes, providing just the right support force to ensure smooth material transmission and reduce jamming and friction.
