Processing equipment for polyethylene film

Abstract

The invention discloses processing equipment for a polyethylene film. The processing equipment comprises a winding drum device, a supporting table, a displacement device, a cutting assembly, a first guide plate and a second guide plate. The cutting assembly comprises a cutter, a plurality of upper rotating rollers and a plurality of elastic ropes, the cutter is provided with a cutting edge and a cutter head, and a first spring and a vertical rod are arranged at the bottom of the cutter head. The supporting table comprises a supporting body, a plurality of positioning assemblies, a pin column, a lantern ring and a connecting block, a vertical sliding groove, a rotating roller seat, a first spring seat and a vertical rod seat are arranged on the connecting block, the pin column is in sliding connection with the vertical sliding groove, the first spring is located in the first spring seat, and the vertical rod can slide in the vertical rod seat, and the upper rotating roller is in sliding connection with the rotating roller seat. Barreled polyethylene film is cut out through the cutter, in the process, the upper rotating rollers and the displacement device extrude the polyethylene film to press and flatten the polyethylene film, the end of the polyethylene film is prevented from being bonded after cutting, the defects in the prior art are overcome, the polyethylene film barrel forming effect is improved, manual secondary treatment is reduced, and production is accelerated.

Description

technical field [0001] The invention belongs to the technical field of polyethylene film production, and in particular relates to a processing equipment for polyethylene film. Background technique [0002] Polyethylene plastic film is a common plastic product. It can be produced by calendering, extrusion, blow molding and other processes. The blown film is to melt and extrude the plastic raw material into a thin tube through an extruder, and then Inflate it with compressed air, and then get the film product after cooling and shaping. In the prior art, the prepared film products are often wound on a paper tube, and after the polyethylene film is rolled to a certain thickness, it needs to be cut manually or by a machine. Since the polyethylene film is thin, the thickness is generally 0.01 ∽0.25mm, during production, the ends of the polyethylene film after cutting are often attracted to each other and bonded together due to the influence of internal tension and inertia, making...

Problems solved by technology

In the prior art, the prepared film products are often wound on a paper tube, and after the polyethylene film is rolled to a certain thickness, it needs to be cut manually or by a machine. Since the polyethylene film is thin, the thickness is generally 0.01 ∽0.25mm, during production, the ends of the polyethylene film after cutting are often attracted to each other and bonded together due to the influence of internal tension and inertia, making the end of the film roll uneven and affecting the appearance of the product; The ends need to be manually flattened slowly, which increases the workload of manual processing and affects the packaging progress of polyethylene film rolls
