AI Technical Summary
When the thickness of the film roller of the existing laminating machine decreases, the linear speed remains unchanged, resulting in a decrease in the rotation radius, an increase in the angular velocity, an increase in the tension on the film cloth, and an increase in the traction force, which cannot be effectively adjusted.
A movable adjusting roller is used to adjust the angle of the membrane cloth, and the tension is automatically adjusted through elastic parts and sliding mechanisms. The coordination of balls and sliders ensures stability. The adjusting roller deforms when the tension increases to adjust the tension.
The automatic adjustment of the film cloth tension is realized, the stability of the laminating process and the accuracy of the tension adjustment are improved, and the problem of excessive traction caused by increased tension is avoided.

Technical Field
[0001] The utility model belongs to the technical field of laminating devices, in particular to a laminating device with adjustable tension. Background Art
[0002] Laminating machines have been widely used in the printing and graphic advertising industries, playing a key role in improving the quality of printed products.
[0003] During the lamination process, as the thickness of the film-laying roller continues to decrease, that is, the pay-off radius continues to decrease, and the linear speed remains unchanged, the reduction in the rotation radius will lead to an increase in angular velocity. In other words, the number of rotations of the pay-off roller being stretched increases, the traction force on the film cloth increases, and the tension it is subjected to increases.

[0005] The tension-adjustable laminating device includes a base plate, a film-releasing roller and a laminating roller installed on the base plate, and an adjusting roller movably connected to the base plate. The middle part of the adjusting roller is connected to the connecting plate through a rotating rod. The connecting plate is connected in the mounting side plate. The end of the mounting side plate is connected to the connecting bottom plate. The outer side of the connecting bottom plate is connected to the fixed bottom plate under the action of a sliding mechanism. The fixed bottom plate is installed on the base plate. The outer side of the connecting bottom plate is connected to an elastic part, and the outer side of the elastic part is connected to the fixed bottom plate.
[0006] The angle at which the membrane cloth is stretched is adjusted by a movable adjusting roller, thereby adjusting the tension of the membrane cloth. When the tension of the membrane cloth increases, the adjusting roller can be driven to move and cause the elastic part to deform to form automatic adjustment of the tension.
[0007] As a preferred embodiment of the above technical solution, a ball is rollingly embedded in the inner wall of the fixed side plate, and the outer wall inside the ball rolls against the outer wall of the installation side plate.
[0008] Under the rolling action of the balls, the stability of the movement of the mounting side panel in the fixed side panel is guaranteed.
[0009] As a preferred embodiment of the above technical solution, the sliding mechanism includes a slider connected to the outer side of the connecting base plate, and the slider slides on the slide rod, the slide rod is installed in a limit groove, the limit groove is symmetrically opened on the inner wall of the fixed side plate, and the outer side of the fixed side plate is connected to the fixed base plate.
[0010] Under the sliding action of the slider and the slide rod, the connecting bottom plate cooperates with the elastic potential energy of the elastic member to drive the adjusting roller to perform automatic adjustment work with adjustable tension.
[0011] The beneficial effects of the utility model are:
[0012] In this application, the angle at which the membrane cloth is stretched is adjusted by a movable adjusting roller, thereby adjusting the tension of the membrane cloth. When the tension of the membrane cloth increases, the adjusting roller can be driven to move and cause the elastic member to deform to form automatic adjustment of the tension.
