Description

Technical Field

[0001] The invention relates to the technical field of plastic waste recycling, in particular to a solid waste recycling device for processing plastic combs. Background Art

[0002] The production of plastic combs, especially those with metal springs, such as massage combs or foldable combs, often produces defective products or scrap due to process fluctuations or lax quality control in injection molding and assembly. This scrap material is typically composed of a mixture of plastic and metal springs. Directly discarding this material not only wastes resources but also increases the environmental burden. Traditional manual sorting or simple crushing recycling methods present the following problems: The metal springs are tightly integrated with the plastic, making effective separation difficult with conventional crushing equipment, necessitating subsequent manual screening, which is time-consuming and labor-intensive. Existing mechanical crushing methods can easily damage the spring structure, resulting in metal debris mixed with the shredded plastic fragments, affecting the melt quality and reuse value of the recycled plastic. Some recycling equipment uses centrifugal separation technology, but for plastic combs with springs, it is difficult to achieve both sufficient plastic pulverization and protection of the spring's integrity during crushing. During centrifugation, the plastic melt easily remains on the walls of the separation tube, requiring additional scraping mechanisms. Automated spring collection relies on complex mechanical structures, resulting in insufficient equipment reliability. Therefore, there is an urgent need to develop an automated device that integrates crushing, separation, melting recovery and spring discharge to improve the recycling efficiency and resource utilization rate of waste plastic combs with springs.

The transfer motor 115 drives the transfer shaft 116 to rotate through the belt drive, and the plastic fragments and springs in the transfer box 104 are conveyed to the output pipe 207 through the transfer shaft 116. Finally, the plastic fragments and springs enter the centrifugal separation cylinder 214 through the output pipe 207, the lower transfer pipe 206, the upper transfer pipe 205 and the input pipe 204. The outer motor 203 drives the outer wheel 211, the inner shaft 212 and the centrifugal cylinder 214 to rotate through the belt drive, and the inner motor 208 drives the outer shaft 209 and the scraper 210 to rotate through the belt drive, and the rotation direction of the scraper 210 is opposite to the rotation direction of the centrifugal cylinder 214.

The centrifugal cylinder 214 rotates rapidly to throw the melted plastic liquid out of the holes in the centrifugal cylinder 214, and finally falls on the output shaft 216. The output motor 215 drives the output shaft 216 to rotate through the belt drive, and the plastic liquid is sent to the discharge pipe 221 through the output shaft 216.

Finally, the plastic cut into equal length segments slides out from the discharge slide 302 for collection.

[0043] Since the spring will not be melted, it will remain in the centrifugal separation cylinder 214. When the spring in the centrifugal separation cylinder 214 accumulates to a certain amount, the plastic comb is first stopped, and then the centrifugal separation cylinder 214 continues to rotate for a period of time, and then stops.
