Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyurethane insulation board production technology, and in particular to a polyurethane insulation board cutting debris recycling device. Background Technology
[0002] Currently, the cutting and production process of polyurethane insulation boards generates a large amount of cutting debris of varying sizes. In order to avoid resource waste and save production costs, a certain recycling device is usually used to crush and heat-melt these debris for recycling, so as to achieve the secondary use of the corresponding materials.
[0003] Currently, when crushing recycled polyurethane insulation board fragments, most methods involve secondary filtration to obtain finer particles. However, existing fragment recycling devices often leave unqualified particles on the filter plates after crushing and filtration, significantly impacting subsequent filtration and requiring manual removal by workers, increasing their workload. While some recycling devices incorporate conveyor mechanisms to transport the fragments upwards for secondary crushing, ensuring finer particles, the upward-conveyed fragments overlap with newly added fragments, resulting in a larger amount of fragments at the crushing point. This not only affects crushing efficiency but also increases wear and tear, shortening the device's lifespan.
[0004] Therefore, it is necessary to provide a polyurethane insulation board cutting scrap recycling device to solve the above-mentioned technical problems. Utility Model Content

All grinding plates 5 are rotatably connected to the rotating shaft 8. Grinding blocks 9 and spiral blades 18 are fixedly connected to the outer surface of the rotating shaft 8. A stirring assembly is provided on the rotating shaft 8. Through the arrangement of the recycling frame 1, grinding plates 5, feeding, rotating shaft 8, grinding blocks 9 and crushing roller 12, the crushed material can be directly stirred and ground to form fine particles that are fed into the machine. This prevents the material from accumulating and clogging the feeding hole 6, which would affect the filtration efficiency. It also avoids the problem of excessive material at the crushing point when the material is conveyed upwards and refilled for secondary crushing, which would not only affect the crushing efficiency but also increase wear at the crushing point and affect the service life of the device. This improves the practicality of the device.
[0032] The crushing assembly includes two crushing rollers 12 and a second motor 13. Both crushing rollers 12 are rotatably connected to the inner wall of the feeding frame 10. One end of each crushing roller 12 is fixedly connected to a gear 14, and the two gears 14 mesh with each other. The second motor 13 is fixedly installed on one side of the feeding frame 10, and the output end of the second motor 13 is fixedly connected to the other end of one of the crushing rollers 12. Through the setting of the crushing assembly, the recycled scrap can be crushed into small particles.
[0033] A support frame 15 is fixedly connected to the bottom of the recycling frame 1, and a protective cover 16 is fixedly connected to the top of the support frame 15. The motor 7 is fixedly installed on the top of the support frame 15 and is located inside the protective cover 16. The rotating shaft 8 rotates through the protective cover 16.

[0035] Working principle: When in use, start motor 13, which drives one of the crushing rollers 12 and the corresponding gear 14 to rotate. Under the transmission of the other gear 14, the other crushing roller 12 rotates synchronously. Then, add the crushed material to be crushed into the hopper 11. The two rotating crushing rollers 12 crush the material. After the material is crushed, it falls onto the grinding plate 5. Then, start motor 7, which drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the stirring rod and grinding block 9 to rotate synchronously. After the stirring rod rotates, it drives the bevel gear 22 and the ring frame 3 to rotate synchronously. With the cooperation of the bevel gear ring 20, the bevel gear 22 rotates, which drives the stirring rod to rotate, stirring the crushed material that falls onto the grinding plate 5. The fine crushed material falls through the discharge hole 6. After the grinding block 9 rotates, it can cooperate with the grinding plate 5 to grind some of the stirred crushed material, forming fine particles. These particles are then discharged into the collection hopper 17 through the discharge hole 6 and are driven by the rotating spiral blades 18 for rapid discharge.
