Description

Technical Field

[0001] The utility model relates to the technical field of waste plastic processing and recycling, in particular to a waste plastic hot-melt recycling and regeneration device. Background Art

[0002] Waste plastic is a popular term, not just referring to waste and useless plastic products. For most plastic products, the properties of the plastic material itself have not changed much after use, so it is entirely possible to recycle them and reprocess them into plastic products using appropriate methods and then use them again.

[0003] Chinese patent authorization announcement number CN214871983U discloses a waste plastic processing and recycling equipment, including a processing box. The waste plastic processing and recycling equipment rotates the rotating assembly so that the upper gear drives the lower gear to rotate synchronously under the action of the second belt. The upper gear rotates to make the upper rack plate drive the slider to move to the right so that the waste plastic enters the crushing box from the feed hopper for crushing. At this time, the lower gear rotates to make the lower rack plate drive the slider to move to the left, so that the slider blocks the discharge pipe. When the waste plastic in the crushing box is certain, the upper gear rotates in the opposite direction to make the upper rack plate push the slider to move to the left, preventing the waste plastic from entering the crushing box. The crushing box, at this time, the rack plate below drives the slider to move to the right, so that the crushed powder falls into the push box and is pushed by the T-shaped push rod into the melting box for melting, thereby realizing indirect crushing of waste plastics. The crushing effect is good and it is not easy to be blocked, which is beneficial to improving the recycling efficiency; the above-mentioned prior art scheme has the following shortcomings: since the waste plastics need to be heated and melted during the recycling process, some waste plastics will be mixed with some metal materials during the recycling process, such as waste integrated circuit boards, etc. If the metal materials are not removed, the use performance of the recycled plastics will be affected. Therefore, it is necessary to design a waste plastic hot melt recycling device to solve the above problems. Utility Model Content
