Thin film winding machine

Abstract

The invention discloses a thin film winding machine which comprises a winding machine rack. The rack comprises a rack base and rack walls erected on the two sides of the rack base. The thin film winding machine further comprises a winding drum erected between the rack walls. The winding drum is rotationally connected to the rack walls on the two sides through a rotary shaft. The winding drum is connected with a winding drum drive device. The drive device comprises a chain wheel set connected with the rotary shaft and a motor used for driving the chain wheel set to rotate. A movable pressure roller is arranged on the outer side of the winding drum and is parallel to the winding drum. The pressure roller makes contact with thin film on the winding drum and is connected with an automatic regulating device used for keeping the pressure roller tightly pressing the thin film at constant pressure. The winding drum drive device and the automatic regulating device are electrically connected toa control cabinet at one side of the rack walls. The thin film winding machine provided by the invention is orderly in thin film winding and high in winding efficiency.

Description

technical field [0001] The invention relates to the field of film printing equipment, in particular to a film winding machine. Background technique [0002] Winder is a kind of winding machine, which is widely used in metallurgy, paper printing, chemical fiber, textile printing and dyeing industries. Film winding is the most complicated among all kinds of soft web materials. This is because: (1) There are many types of plastic films, and the formulations of resin raw materials are different, so the properties of film materials are complex and changeable. The winding shows different characteristics and requirements; (2) the film in the winding is not only the processed object but also participates in the transmission of motion and power as a transmission part. The film itself is neither a rigid body nor a pure elastic body, showing a strong The viscoelastic characteristics make its dynamic and motion characteristics more complicated. Therefore, in the prior art, there are of...

Film winding is the most complicated among all kinds of soft web materials. This is because: (1) There are many types of plastic films, and the formulations of resin raw materials are different, so the properties of film materials are complex and changeable. The winding shows different characteristics and requirements; (2) the film in the winding is not only the processed object but also participates in the transmission of motion and power as a transmission part. The film itself is neither a rigid body nor a pure elastic body, showing a strong The viscoelastic characteristics make its dynamic and motion characteristics more complicated. Therefore, in the prior art, there are often wrinkles, uneven winding, and unsmooth phenomena during the winding process of the film. Insufficient adjustment accuracy of tightness and uneven slack
