Intermediate device for winding plastic films

Abstract

The invention provides an intermediate device for winding plastic films. The intermediate device comprises a center shaft, a first bracket and a second bracket; the first bracket and the second bracket are movably arranged on the center shaft; first winding rollers are arranged at two ends of the first bracket; second winding rollers are arranged at two ends of the second bracket; guide rollers are respectively arranged on the first bracket and the second bracket; support rollers are respectively arranged at two ends of the first bracket and the second bracket; the first winding rollers and the second winding rollers both adopt hollow structures; absorbing devices are arranged in the first winding rollers and the second winding rollers; absorbing through holes are uniformly formed in the first winding rollers and the second winding rollers; absorbing tube sleeves are arranged on the outer sides of the first winding rollers and the second winding rollers; the absorbing devices are connected with negative-pressure generation devices through pipelines; rotating speed sensors are arranged on the first winding rollers and the second winding rollers; and output ends of the rotating speed sensors are connected with switches of the negative-pressure generation devices. The intermediate device is simple in structure and reasonable in design, increases the number of the winding rollers, improves the winding efficiency, and saves the production cost.

Description

technical field [0001] The invention relates to the technical field of plastic machinery, and more specifically relates to an intermediate device for processing winding plastic films. 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 materials,...

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
