Efficient open mill for thin film production

Abstract

The invention provides an efficient open mill for thin film production and relates to the technical field of plastic processing. The efficient open mill comprises a rack, and a first roller, a secondroller, a first motor and a second motor are arranged on the rack. The first roller is connected with the first motor, and the second roller is connected with the second motor. A material turning mechanism is further arranged on the rack and comprises a supporting rod and a material turning plate; the two ends of the supporting rod are fixedly connected with the rack; the rear portion of the material turning plate is connected with an air cylinder; the two ends of the material turning plate are provided with side plates fixedly connected with connecting rods; the upper ends of the connecting rods are rotatably connected with the supporting rod, and rolling wheels are arranged at the lower ends of the connecting rods; and a guide groove allowing the rolling wheels to slide is further formedin the rack. The efficient open mill has the beneficial effects that safety is high, mixing materials can be thoroughly turned, the material turning effect is enhanced, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a high-efficiency mill for producing films. Background technique [0002] Open mixer is the abbreviation of open rubber mixing machine. It is a kind of rubber mixing machine with exposed rollers used by plastic factories to prepare plastic rubber, mixed rubber or heat refining and extrusion. The main working parts of the open mixer It is two hollow rollers or drilled rollers that rotate inward in different directions. The two rollers rotate relative to each other at different speeds. To achieve the purpose of mastication or mixing. [0003] However, the disadvantages of the current mill are that the degree of automation is low, and the physical exertion of the workers is very high, because in the process of milling, the number of times of flipping and mixing plastic sheets has a great influence on the quality of raw material mixing. , but at present, the material is ...

Problems solved by technology

[0003] However, the disadvantages of the current mill are that the degree of automation is low, and the physical exertion of the workers is very high, because in the process of milling, the number of times of flipping and mixing plastic sheets has a great influence on the quality of raw material mixing. , but at present, pure manual turning is used, which is labor-intensive, and is close to the roller to turn the mixed material in a relatively high temperature environment. The working environment is poor and it is easy to cause discomfort.

Application No. 201620260962.5 discloses the invention patent of "an automatic material turning device for plastic mill". The device is equipped with a rotating shaft and a material turning mechanism. The material plate realizes the automatic cutting and turning of the mixing material by the material turning mechanism; but it is not difficult to see that the material turning effect of this device is not particularly ideal, and only a small part of material turning can be carried out. If the material turning is not complete, it will directly affect to the result of mixing
