Plastic film machining device with absorbing and winding functions

Abstract

The invention discloses a plastic film machining device with absorbing and winding functions. The device comprises a center shaft, a winding roller bracket and a support roller bracket; the center shaft is movably provided with the winding roller bracket and the support roller bracket; winding rollers are arranged at two ends of the winding roller bracket; support rollers are arranged at two ends of the support roller bracket; guide rollers are arranged on the support roller bracket; the winding rollers adopt hollow structures; absorbing devices are arranged in the winding rollers; absorbing through holes are uniformly formed in the winding rollers; absorbing sleeves are arranged on the outer sides of the winding rollers; and the absorbing devices are connected with negative-pressure generation devices through pipelines. The device is simple in structure and reasonable in design; the winding roller bracket and the support roller bracket are movably arranged on the center shaft, and can be overturned around the center shaft to enable the winding rollers to alternately work; the winding rollers needing to be replaced are replaced after being overturned to the outer side, so that the mechanical operation is convenient; and when plastic films are wound, and perform a cutting procedure after winding, as the absorbing devices are arranged in the winding rollers, the plastic films cannot be scattered in the cutting process.

Description

technical field [0001] The invention relates to the technical field of plastic machinery, more specifically, to a plastic film processing device with the functions of adsorption and winding. Background technique [0002] According to the production process of plastic products, plastic machinery can be divided into four categories: plastic compounding machinery, plastic molding machinery, plastic secondary processing machinery and plastic processing auxiliary machinery or devices. The perfection of plastic machinery directly affects the quality, output and cost of plastic semi-finished products or products, so it must be able to adapt to changes in temperature and stress during plastic compounding and processing, as well as the resulting changes in the properties of molten materials, and to adapt to chemical corrosion and mechanical wear and other special conditions. The specialization of plastic grades, the development of engineering plastics, the emergence of composite mat...

Problems solved by technology

In the prior art, the rewinding device used for rewinding the plastic film is very troublesome when replacing the rewinding rollers. Generally, different rewinding rollers are installed to achieve alternate and continuous rewinding of the plastic film, but the rewinding rollers arranged on the inside It is inconvenient to remove the winding roller after the winding is completed, and it is also inconvenient to replace the winding roller
