Problems solved by technology
[0004] (1) When the volume of waste foam plastic is large, if it is rubbed directly, it will take a long time for the processing equipment to be able to contact the foam plastic in the center, and some foam plastic still has not become particles after processing shape, the processing is not thorough enough;
[0005] (2) If the foam plastic is cut before kneading, the thoroughness of the kneading process can be improved and the number of block foam plastics can be reduced. However, because the foam plastic is prone to static electricity after friction, the foam plastic often sticks. Attached to the slitting tool, which affects the normal progress of the slitting work and delays the work process

Embodiment Construction
[0032] In order to make the technical means realized by the present invention, creative features, goals and effects easy to understand, the following combination Figure 1 to Figure 4 , to further elaborate the present invention.
[0033] A method for recycling waste foam plastics, mainly comprising the following processing steps:
[0034] S1. Foam collection: Collect waste foam plastics manually, and screen out impurities mixed in foam plastics;
[0035] S2. Feeding: Put the foamed plastics into the recycling equipment manually. After the foamed plastics enter the recycling equipment, there should be a gap between the foamed plastics;
[0036] S3. Foam cutting: start the recycling equipment, cut the large foam plastic into smaller foam blocks, and after the cutting is completed, the foam blocks with the required size can fall down;
[0037] S4. Foam block granulation: use recycling equipment to granulate the foam blocks that have reached the required size after cutting, so ...

The invention relates to a recycling method of waste foamed plastic. The method mainly comprises the following steps of S1, foam collection; S2, feeding; S3, foam slitting; S4, foam block grain rubbing and S5, discharging. A recycling device used in S2, S3 and S4 comprises a rack, a connecting frame, an upper cylinder, a lower cylinder, a screen plate, a slitting mechanism and a grain rubbing mechanism. The connecting frame is mounted on the upper end of the rack, and is of a hollow cylindrical structure, the upper end of the connecting frame is provided with the upper cylinder through a screw, the lower end of the connecting frame is provided with the lower cylinder through a screw, the slitting mechanism is arranged in the upper cylinder, the grain rubbing mechanism is arranged in the lower cylinder, the screen plate is arranged between the upper cylinder and the lower cylinder, and the screen plate is mounted on the connecting frame. Through fit between the slitting mechanism and the grain rubbing mechanism, machining work of waste foam plastic can be finished, normal operation of the machining work can be ensured, the upper cylinder and the slitting mechanism are detachably connected, and the slitting mechanism can be conveniently overhauled and replaced.
Description
technical field [0001] The invention relates to the technical field of foam recycling, in particular to a method for recycling waste foam plastics. Background technique [0002] Styrofoam is a kind of chemical material, the full name is polystyrene foam, because of its light weight, firmness, shock absorption, low moisture absorption, easy molding, good water resistance, heat insulation, and low price, it is widely used in packaging It is one of the most widely used plastics in the world today, in the fields of thermal insulation, waterproof, heat insulation, shock absorption, etc. The corresponding discarded foam plastics also cause serious "white pollution". Foam plastics are not perishable in nature and are also Not easily degraded by microorganisms. If it is simply incinerated, it will seriously pollute the air and atmospheric environment. The recycling of waste foam plastics can not only reduce environmental pollution, but also turn waste into wealth and save energy, ...
