Description

Technical Field

[0001] This utility model relates to the field of pearl cotton production technology, specifically to a waste recycling and processing device for pearl cotton production. Background Technology

[0002] EPE foam, also known as polyethylene foam, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also has excellent chemical resistance, making it an ideal substitute for traditional packaging materials. During the processing of EPE foam, it needs to be cut or trimmed to achieve the desired shape, thus generating EPE foam waste, i.e., EPE foam scraps. To recycle and reuse EPE foam, waste recycling and processing equipment is required to collect this waste.

[0003] Existing waste recycling and processing equipment for EPE foam production first crushes the EPE foam waste using crushing equipment, then melts it in a hot-melt equipment, and finally extrudes and cools it into shape using a molding equipment. Finally, a cutting equipment cuts the extruded and cooled EPE foam waste into smaller particles for recycling. However, the existing waste recycling and processing equipment consists of separate and independent crushing, hot-melt, molding, and cutting equipment, each requiring conveyor systems. This results in a large footprint, consumes significant resources during operation, and incurs high maintenance costs for multiple devices, thus increasing the overall cost of EPE foam waste recycling. Utility Model Content

[0004] The purpose of this utility model is to provide a waste recycling and processing device for EPE foam production, which integrates multiple devices, reduces floor space, reduces resource consumption, and reduces recycling costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste recycling and processing device for pearl cotton production, comprising a base, a conveying cylinder with an open right end disposed above the base, a heating plate cylinder fixedly connected to the inner wall of the conveying cylinder, a forming block fixedly connected to the right end of the conveying cylinder, a rotating shaft rotatably connected to the left inner side wall of the conveying cylinder and located inside the heating plate cylinder, the right end of the rotating shaft extending to the right side of the forming block and fixedly connected to a cutting blade abutting against the right side wall of the forming block, and a spiral conveying blade matching the inner wall of the heating plate cylinder fixedly connected to the outer wall of the rotating shaft, the right end of the spiral conveying blade abutting against the left side wall of the forming block;

[0006] The right side wall of the molding block has multiple uniformly distributed molding holes that communicate with the heating plate cylinder, and the interior of the molding block is equipped with cooling pipes surrounding the multiple molding holes.

[0007] A crushing box is provided above the conveying cylinder. A material passage is connected between the crushing box and the heating plate cylinder. Two crushing rollers are rotatably connected inside the crushing box, which are distributed on the left and right and matched with each other. One end of each crushing roller extends to the rear of the crushing box and is fixedly connected to meshing gears.

[0008] In order to drive the rotating shaft to rotate, as a preferred embodiment of the waste recycling and processing device for pearl cotton production according to this utility model, a first motor is installed on the left side wall of the conveying cylinder, and the output end of the first motor is fixedly connected to the rotating shaft.

[0009] In order to drive one of the crushing rollers to rotate, as a preferred embodiment of the waste recycling and processing device for pearl cotton production of this utility model, a second motor is installed on the front end of the crushing box, and the output end of the second motor is fixedly connected to one of the crushing rollers.

[0010] To facilitate the connection between external pipes and cooling pipes, in a preferred embodiment of the waste recycling and processing device for pearl cotton production according to this utility model, both ends of the cooling pipe extend above the molding block and are equipped with quick-release connectors.

[0011] In order to support the conveying cylinder and the forming block, as a preferred embodiment of the waste recycling and processing device for pearl cotton production of this utility model, the base is fixedly connected to two left and right distributed support blocks.

[0012] In order to support the crushing box, as a preferred embodiment of the waste recycling and treatment device for pearl cotton production of this utility model, a plurality of evenly distributed support rods are fixedly connected between the crushing box and the support block located on the far left.

[0013] To facilitate the addition of waste pearl cotton to the crushing box, as a preferred embodiment of the waste recycling and processing device for pearl cotton production according to this utility model, the upper end face of the crushing box is connected to a feeding chute.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The waste EPE foam is crushed by two crushing rollers and conveyed by a spiral conveyor. Simultaneously, the waste EPE foam is heated and melted by a heating plate cylinder and then extruded by the spiral conveyor, forcing it into multiple forming holes. The formed blocks are then cooled by cold water in cooling pipes. A cutting blade then cuts the cooled and shaped waste EPE foam into small particles, which are then collected and recycled through an integrated waste EPE foam recycling and processing device. This effectively reduces the floor space required. Furthermore, the integrated waste EPE foam recycling and processing device has fewer drive mechanisms, reducing resource consumption and recycling costs. Attached Figure Description

[0021] Please see Figures 1 to 3 A waste recycling and processing device for pearl cotton production includes a base 1. A conveying cylinder 2 with an open right end is arranged above the base 1. A heating plate cylinder 3 is fixedly connected to the inner wall of the conveying cylinder 2. A forming block 4 is fixedly connected to the right end of the conveying cylinder 2. A rotating shaft 5 located inside the heating plate cylinder 3 is rotatably connected to the left inner side wall of the conveying cylinder 2. The right end of the rotating shaft 5 extends to the right side of the forming block 4 and is fixedly connected to a cutting blade 6 that abuts against the right side wall of the forming block 4. A spiral conveying blade 7 that matches the inner wall of the heating plate cylinder 3 is fixedly connected to the outer wall of the rotating shaft 5. The right end of the spiral conveying blade 7 abuts against the left side wall of the forming block 4.

[0022] The right side wall of the molding block 4 has multiple uniformly distributed molding holes 8 that are connected to the heating plate cylinder 3. Cooling pipes 9 are installed inside the molding block 4, which surround the multiple molding holes 8.

[0023] A crushing box 10 is provided above the conveying cylinder 2. The crushing box 10 is connected to the heating plate cylinder 3 by a material passage pipe 11. Inside the crushing box 10, there are two crushing rollers 12 that are distributed on the left and right and matched with each other. One end of each crushing roller 12 extends to the rear of the crushing box 10 and is fixedly connected to a meshing gear 13.

[0024] In this embodiment: When in use, first connect the external cold water delivery pipe and return pipe to both ends of the cooling pipe 9, then put the waste pearl cotton into the crushing box 10 through the feed trough 19, then one of the crushing rollers 12 rotates, and one of the crushing rollers 12, together with two gears 13, drives the other crushing roller 12 to rotate, thereby crushing the waste pearl cotton through the two crushing rollers 12, and the crushed waste pearl cotton enters the heating plate cylinder 3 through the feed pipe 11;

[0025] Then the rotating shaft 5 rotates, which drives the spiral conveyor blade 7 and the cutting blade 6 to rotate. The spiral conveyor blade 7 conveys the crushed pearl cotton waste. At the same time, the heating plate cylinder 3 is started (the heating temperature of the heating plate cylinder 3 is set to the temperature that just melts the pearl cotton waste, and the temperature inside the heating plate cylinder 3 is monitored by the temperature sensor installed inside the heating plate cylinder 3). The pearl cotton waste is heated and melted by the heating plate cylinder 3. When the pearl cotton waste is conveyed to the forming block 4, the pearl cotton waste is melted.

[0026] Then, the molten EPE foam waste is extruded by the spiral conveyor blades 7, forcing it into multiple forming holes 8. Cold water is then supplied to the cooling pipes 9 via an external cold water supply pipe. The cold water in the cooling pipes 9 cools the forming blocks 4, thereby cooling the molten EPE foam waste within the multiple forming holes 8 (the cold water is in a circulating state, and the cooled hot water is cooled by a chiller or a cooling tower in the factory). This allows the molten EPE foam waste to cool and solidify rapidly. The cooled and solidified EPE foam waste is then continuously pushed by the subsequent conveying of molten EPE foam waste. Because it is moving, the cooled and shaped EPE foam waste is in a continuous moving state and will not block the forming holes 8. When the cooled and shaped EPE foam waste is discharged from the right end of the multiple forming holes 8, the rotating shaft 5 drives the cutting blade 6 to cut the cooled and shaped EPE foam waste into small particles. Then, the small particles of EPE foam waste are collected and recycled through the integrated EPE foam waste recycling and processing device, which effectively reduces the floor space occupied. At the same time, the integrated EPE foam waste recycling and processing device has fewer drive mechanisms, which can reduce resource consumption and reduce the recycling cost of EPE foam waste.

[0027] As a technical optimization of this utility model, a first motor 14 is installed on the left side wall of the conveying cylinder 2, and the output end of the first motor 14 is fixedly connected to the rotating shaft 5.

[0028] In this embodiment: the first motor 14 is started, and the first motor 14 drives the rotating shaft 5 to rotate.

[0029] As a technical optimization of this utility model, a second motor 15 is installed on the front end face of the crushing box 10, and the output end of the second motor 15 is fixedly connected to one of the crushing rollers 12.

[0030] In this embodiment: the second motor 15 is started, and the second motor 15 drives one of the crushing rollers 12 to rotate.

[0031] As a technical optimization of this utility model, both ends of the cooling pipe 9 extend above the molding block 4 and are equipped with quick-release connectors 16.

[0032] In this embodiment, the quick-release connector 16 facilitates the connection between the external pipe and the cooling pipe 9.

[0033] As a technical optimization of this utility model, two left and right distributed support blocks 17 are fixedly connected between the base 1, the conveying cylinder 2, and the forming block 4.

[0034] In this embodiment, the support block 17 can support the conveying cylinder 2 and the forming block 4.

[0035] As a technical optimization of this utility model, a plurality of evenly distributed support rods 18 are fixedly connected between the crushing box 10 and the leftmost support block 17.

[0036] In this embodiment, the support rod 18 can support the crushing box 10.

[0037] As a technical optimization of this utility model, the upper end face of the crushing box 10 is connected to the feed chute 19.

[0038] In this embodiment, the feed trough 19 facilitates the addition of pearl cotton waste into the crushing box 10.

[0039] Working principle: In use, first connect the cold water external delivery pipe and return pipe to both ends of the cooling pipe 9 through the quick-release connector 16. Then, put the pearl cotton waste into the crushing box 10 through the feed chute 19. Then, control the second motor 15 to start through the external control panel. The second motor 15 drives one of the crushing rollers 12 to rotate. One crushing roller 12, in conjunction with two gears 13, drives the other crushing roller 12 to rotate. The two crushing rollers 12 then crush the pearl cotton waste. The crushed pearl cotton waste enters the heating plate cylinder 3 through the feed pipe 11.

[0040] Then, the first motor 14 is started by controlling the external control panel. The first motor 14 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the spiral conveyor blade 7 and the cutting blade 6 to rotate. The spiral conveyor blade 7 conveys the crushed pearl cotton waste. At the same time, the heating plate cylinder 3 is started by controlling the external control panel. The heating plate cylinder 3 heats and melts the pearl cotton waste. When the pearl cotton waste is conveyed to the forming block 4, the pearl cotton waste is melted.

[0041] Then, the molten EPE foam waste is extruded by the spiral conveyor blades 7, forcing it into multiple forming holes 8. Cold water is then supplied to the cooling pipes 9 via an external cold water supply pipe. The cold water in the cooling pipes 9 cools the forming block 4, thereby cooling the molten EPE foam waste within the multiple forming holes 8. This allows the molten EPE foam waste to cool and solidify rapidly. The cooled and solidified EPE foam waste is further propelled by the continuous conveying of molten EPE foam waste. Therefore, the cooled and solidified EPE foam waste is... In continuous movement, the forming holes 8 will not be blocked. When the cooled and shaped EPE foam waste is discharged from the right end of the multiple forming holes 8, the rotating shaft 5 drives the cutting blade 6 to cut the cooled and shaped EPE foam waste into small particles. Then, the small particles of EPE foam waste are collected and recycled through the integrated EPE foam waste recycling and processing device, which effectively reduces the floor space. At the same time, the integrated EPE foam waste recycling and processing device has fewer drive mechanisms, which can reduce resource consumption and reduce the recycling cost of EPE foam waste.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
