Description

Technical Field

[0001] The utility model relates to the technical field of film winding machines, in particular to a swing device used for film winding machines. Background Art

[0002] The material receiving part of the coil processing production line mechanically reels the raw materials into coils. It is widely used in paper rolls, cloth rolls, plastic rolls, and metal coil processing production lines. The design is diversified according to the actual process requirements. Common ones include simple rewinders and hydraulic rewinders. Rewinders generally have strict requirements on the inner diameter, outer diameter, thickness, and width of the material.

[0003] When the film is wound up after production, the winding device is swung to meet the need for uniform winding. A Chinese patent discloses a swinging device for a film winder (authorization announcement number CN213011066U). This patented technology can drive the worm to rotate by controlling the forward and reverse motors, and the worm drives the gear to rotate through the turbine and the transmission rod. The gear cooperates with the tooth groove in the through groove to drive the drive plate to move left and right, and the drive plate drives the transition guide roller to move left and right through the drive frame and the connecting rod to change the offset winding situation, thereby automatically avoiding the situation where the end thickness is too thick, thereby improving the winding quality of the device.

[0004] Although this solution can avoid the phenomenon of flipping over caused by excessive thickness and affecting the winding quality in actual use, in actual use, the tightness of the film will affect the winding. This solution does not have a relevant device to control the tightness of the film, which leads to wrinkles when the film is rolled up in a relatively loose state, affecting the winding result.

[0005] In order to solve the above problems, we have made improvements and proposed a swing device for a film winder. Utility Model Content

Under the squeezing of the spring 306, the clamping head 308 penetrates into the inside of the film winding roller, and the film is wound around the outside of the winding roller. The winding roller is driven to rotate by the first motor 304 to achieve the winding of the film. At the same time, as the film moves, the pressure on the adjusting roller 207 is reduced when the film is relaxed, which is detected by the pressure sensor 208 and the relevant data is transmitted To the controller 202, the controller 202 drives the mounting block 205 to drive the adjusting roller 207 to rise, so that the film is taut.
