Description

Technical Field

[0001] This utility model relates to the field of PVC foam board processing technology, specifically to a waste recycling device for PVC foam board processing. Background Technology

[0002] PVC foam boards have a wide range of applications. During the production process, a lot of waste is generated, which is usually collected and recycled.

[0003] A search revealed a patent document, CN202323260775.6, which discloses "a waste recycling device for high-strength PVC foamed boards." The device includes a crushing box, inside which a primary crushing wheel and a secondary crushing wheel are rotatably installed. The primary crushing wheel is used to initially crush the PVC waste, while the secondary crushing wheel is used to further crush the PVC waste crushed by the primary crushing wheel. The resulting powder is blocked in the crushing box by a cover plate on the feed inlet. The crushed waste is discharged into a cloth bag through a connecting pipe using a discharge pipe. The cloth bag is used to further reduce the powder generated when the waste is discharged.

[0004] While this patent can achieve secondary crushing of materials, it still has some problems in use. First, secondary crushing may not completely crush the materials, resulting in some large particles that cannot pass through the filter. Although it has a large particle outlet pipe to remove large particles, manual feeding is still required for further crushing, which is inefficient. Second, the crushed powder is discharged from the bottom feed pipe, which can easily cause blockages. This patent is not convenient for clearing blockages. Therefore, we propose a waste recycling device for PVC foam board processing to solve the problems mentioned in the background technology. Utility Model Content

The waste material from the foam board processing is fed into the feeding cylinder 3. It is initially crushed by the first crushing roller 8 and then guided by the guide plate 5 to be conveyed between the two second crushing rollers 9 for secondary crushing. The filter screen body 11 is used to filter the large particles of waste. The small particles fall to the bottom and are guided by the cylindrical guide block 16 to be discharged at the discharge pipe 12. The large particles of waste enter the feeding cylinder 141 through the feeding pipe 144. After the third motor 142 is turned on, its output shaft drives the auger plate 143 to rotate, which conveys the material to the top and discharges it from the material return pipe 145 to the top of the two first crushing rollers 8. The above work is repeated. When the discharge pipe 12 is blocked, the telescopic part 133 can be opened to drive the unblocking rod 134 to move down to clear the blockage.
