A waste plastic recycling process

technical field

The invention relates to the technical field of resource recycling, in particular to a waste plastic recycling process.

Background technique

The development of the plastic industry has brought great benefits to human beings, but it has left endless troubles, namely "white pollution". Since there are plastic products, old plastics are inevitably produced, and as time goes by, more new raw materials are put into use, resulting in a substantial increase in waste plastics. Because waste plastics are not easy to age and degrade at room temperature, resulting in increasing white pollution and serious damage to the ecological environment, the recycling and reuse of waste plastics has become the top priority. Among them, the waste generated by the paper mill in the production process contains a large amount of plastic film, but the premise is that the waste needs to be screened, and impurities such as sand, iron wire and iron nails used in cartons other than plastic film are removed from the waste. remove.

a rotating wheel (4) is arranged at the upper end of the left part of the frame body (1), the rotating wheel (4) is arranged below the rubber belt (14), and a soft tentacle is arranged on the surface of the rotating wheel (4); after sucking the plastic film, the sucker (18) rotates to the position of the rotating wheel (4) and the plastic film sucked on the sucker (18) is squeezed into the left part of the frame body (1) by a tentacle on the rotating wheel (4) for collection;

when the device works, raw materials are poured into water at the upper right end of the frame body (1), the driving wheel (11) of the starting system rotates to drive the rubber belt (14) to rotate, meanwhile, the cam (2) rotates synchronously, the cam (2) rotates to be matched with the extrusion wheel (17) to extrude the sucker (18), so that the first air bag (15) is extruded through the rubber belt (14), after the sucker (18) rotates away, the air port (19) adsorbs a plastic film in an aqueous solution through the first air bag (15), and when the next cam (2) passes through, the cam (2) cannot extrude the first air bag (15) due to the fact that the first air bag (15) is in a compression state, and different suckers (18) can be extruded at the raised position of one circle of rotation of the cam (2); the continuous work is realized, meanwhile, the cam (2) can extrude the extrusion plate (21) to enable the extrusion plate (21) to drive the extrusion rod (22) to move downwards, the triangular position at the lower end of the extrusion rod (22) pushes the roller (25), so that the swinging rod (23) moves rightwards, when the cam (2) does not extrude the extrusion plate (21), the swinging rod (23) moves leftwards under the action of the second spring (24), so that the extrusion rod (22) drives the extrusion plate (21) to move upwards, the extrusion plate (21) always moves along with the cam (2), the vertical reciprocating movement of the extrusion rod (22) and the left-right reciprocating movement of the swinging rod (23) are realized, the swinging plate (26) is driven to move when the swinging plate (26) moves leftwards, the swinging plate (26) is kept in a vertical state under the resistance action of the limiting block (27) and water, and the garbage deposited on the sewage bearing plate (28) is pushed to the grid pollution discharge machine (29), the water is discharged out of the frame body (1) through the grating sewage discharging machine (29), so that the water resource is kept clean, and the water can be utilized for multiple times; when the swinging plate (26) moves leftwards, the swinging plate (26) keeps an inclined state due to the resistance of water, so that the garbage is prevented from flowing back; the extrusion rod (22) moves up and down to drive the air distribution disc (31) to extrude the second air bag (33), so that gas or liquid in the second air bag (33) is introduced into the frame body (1) through the air holes (34), water in the frame body (1) flows upwards, meanwhile, the extrusion rod (22) moves up and down to drive the gear in the gear box (36) to rotate, so that the impeller (35) is driven to rotate through the flexible shaft (37), the plastic film floats upwards by matching with the second air bag (33), the adsorption rate of the suction disc (18) is increased, and the gear in the gear box (36) only drives the impeller (35) to rotate in a single direction, and the plastic film is prevented from sinking again; after the sucker (18) sucks the plastic film, the plastic film is conveyed to the position of the rotating wheel (4) through the rotation of the rubber belt (14) and is squeezed into the left part of the frame body (1) by a tentacle on the rotating wheel (4) for collection, so that the repeated suction of the sucker (18) is realized, and the working efficiency is improved.
