Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production and processing, in particular to a device for cleaning and recycling leftover materials of degradable plastic bags. Background Art

[0002] Degradable plastic bags are bags made of degradable plastics. They are essential items for storing things in people's daily lives. In order to facilitate people's lifting, double ears are cut and hollowed out during the processing of plastic bags, so that people can put their fingers in to lift them. When the plastic bags are cut, the excess block plastic bags will form scraps, and the scraps formed are collected during the production process. The collected scraps are not directly discarded. In the plastic bag processing plant, the scraps are crushed and recycled. After the scraps are crushed into plastic particles, the plastic particles can be reused in the processing of plastic bags, or the plastic particles can be melted and reused. At present, the crushing equipment used for scrap recycling will generate static electricity when crushing plastics. Depending on the raw materials of the scraps, the plastic particles may adhere to the crushing roller, or they may stick together due to static electricity when crushing and discharging, hindering the dispersion. Most of the current crushing equipment achieves static electricity removal by grounding, but the static electricity removal effect is not good, and it is impossible to eliminate the static electricity generated by scraps made of different raw materials during crushing. Affects the recycling of scrap materials. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0021] See also Figures 1 to 3 The utility model provides a degradable plastic bag scrap cleaning and recycling device, comprising a crushing box 1, a lower hopper 2, a crushing roller 3, an ion fan 4 and a position adjustment mechanism, wherein the top surface of the crushing box 1 is provided with an opening 5, the lower hopper 2 is arranged on the top surface of the crushing box 1 and is connected with the opening 5, the crushing roller 3 is relatively arranged inside the crushing box 1 and is located below the opening 5; the position adjustment mechanism comprises a hydraulic rod 6, a fixed ring 7, a rotating ring 8, a rotating motor 9, a gear 10 and a rack 11, the hydraulic rod 6 is arranged on the top surface of the crushing box 1, and its output shaft is connected with the top surface of the fixed ring 7, the top surface of the rotating ring 8 is rotatably connected with the bottom surface of the fixed ring 7, the rack 11 is arranged along the circumferential direction of the outer wall of the rotating ring 8, the rotating motor 9 is arranged on the outer circumferential surface of the fixed ring 7, and its output shaft is connected with the gear 10, the gear 10 is meshed with the rack 11, and the ion fan 4 is arranged on the bottom surface of the rotating ring 8, and its outlet faces the crushing roller 3.

[0022] The utility model discloses a degradable plastic bag scrap cleaning and recycling device, which is used for crushing and recycling the scraps generated in the plastic production process. The scraps are placed in a lower hopper 2, and the scraps enter a crushing box 1 through an opening 5. Under the action of a crushing roller 3, the scraps can be crushed, and the crushed plastic particles will fall to the inner bottom surface of the crushing box 1. By collecting the plastic particles, resource recovery can be achieved, thereby avoiding waste of resources.

[0023] A rotating ring 8 is arranged around the crushing roller 3, and an ion fan 4 is arranged at the bottom of the rotating ring 8. The ion fan 4 can generate ion wind and blow it toward the crushing roller 3. The ion wind can eliminate the static electricity of the plastic particles adhering to the crushing roller 3 due to static electricity, thereby preventing the plastic particles from adhering to the crushing roller 3. The rotating motor 9 can drive the gear 10 to rotate, and the gear 10 can drive the rotating ring 8 to rotate through the rack 11, thereby rotating the ion fan 4 to different positions of the crushing roller 3, so as to eliminate the static electricity of the plastic particles at different positions.

[0024] In addition to eliminating static electricity on the crushing roller 3, the fixed ring 7 and the rotating ring 8 can also be lowered by the hydraulic rod 6, so that the ion blower 4 can be lowered below the crushing roller 3. The crushed plastic particles may still adhere together due to static electricity, and the ion wind generated by the lowered ion blower 4 can remove the static electricity of the fallen plastic particles, thereby preventing the plastic particles from adhering to each other and making it impossible to effectively recycle them.

[0025] Preferably, a T-shaped ring groove 12 is provided on the bottom surface of the fixed ring 7 , and a T-shaped sliding block 13 is provided on the top surface of the rotating ring 8 , and the T-shaped sliding block 13 is located in the T-shaped ring groove 12 .

[0026] When the rotating motor 9 drives the rotating ring 8 to rotate through the gear 10 and the rack 11, the T-shaped slider 13 on the top thereof can move along the T-shaped ring groove 12 to avoid rotation deviation.

[0027] Preferably, it also includes a discharge port 14 and a conveyor belt 15 , wherein the discharge port 14 is arranged on the side wall of the crushing box 1 , the conveyor belt 15 is arranged on the inner bottom surface of the crushing box 1 and is located on one side of the discharge port 14 , and the crushing roller 3 is located above the conveyor belt 15 .

[0028] The crushed plastic particles fall onto the conveyor belt 15 for transportation, and are finally transported to the outside of the crushing box 1 from the discharge port 14 .

[0029] Preferably, the position adjustment mechanism also includes a sliding plate 16, a force plate 17 and an electric push rod 18, the sliding plate 16 is located below the rotating ring 8, the ion blower 4 is arranged on the bottom surface of the sliding plate 16, the force plate 17 is arranged on the side wall of the sliding plate 16 away from the crushing roller 3, and the electric push rod 18 is arranged on the outer wall of the rotating plate, and its output shaft is connected to the side wall of the sliding plate 16.

[0030] Since the crushing roller 3 has a certain width, when it is necessary to remove static electricity from the plastic particles that fall after crushing, the electric push rod 18 can drive the force plate 17 to move, so that the sliding plate 16 can drive the ion blower 4 to move, so as to get close to the unloading position of the plastic particles, so that the blown ion wind can act on the plastic particles.

[0031] Preferably, the position adjustment mechanism further includes a guide rod 19 , one end of which is arranged on the outer circumference of the rotating ring 8 , and the other end of which extends away from the crushing roller 3 . A through hole 20 is arranged on the force-bearing plate 17 , and the guide rod 19 passes through the through hole 20 .

[0032] In order to ensure the stable movement of the sliding plate 16, a through hole 20 is set on the force-bearing plate 17. When the electric push rod 18 pushes the force-bearing plate 17 to move, the through hole 20 can move along the guide rod 19 to ensure that the movement will not be offset.

[0033] Preferably, the position adjustment mechanism further includes a side plate 21 and an electric turntable 22 , wherein the side plate 21 is relatively arranged on the bottom surface of the sliding plate 16 , and the electric turntable 22 is arranged on the side wall opposite to the side plate 21 , and its rotating surface is connected to the side wall of the ion blower 4 .

[0034] After the ion fan 4 is set between the electric turntables 22, the electric turntable 22 can adjust the angle of the ion fan 4 so that the air outlet direction can be horizontal or downward. When electrostatic adhesion occurs when the plastic particles are transported from the conveyor belt 15 to the discharge port 14, the air outlet direction of the ion fan 4 can be downward to eliminate the static electricity at the discharge port 14.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
