The front end of the transmission pipe is connected with an outer supporting plate through a supporting set. According to the utility model, through three-dimensional cooperative control of height, pressure and amplitude, flexible contact of non-woven fabrics with different gram weights is ensured, multidirectional stress wrinkles in high-speed production can be eliminated, rapid unloading of coiled materials with different diameters is ensured, and fiber layer damage caused by traditional knocking and dismounting can be avoided.

This utility model discloses a die-cutting device, including a mounting frame, a conveyor roller assembly, a tension roller, a first sensor, a second sensor, and a driver. The conveyor roller assembly includes multiple rotatable conveyor rollers mounted on the mounting frame. The tension roller and the multiple conveyor rollers together form a conveyor line for moving the material belt. The tension roller is slidably mounted on the mounting frame in the vertical direction and can tension the material belt downwards under its own weight. The first sensor is used to detect whether the tension roller is in a first position. The second sensor is used to detect whether the tension roller is in a second position, which is below the first position. The driver is drivenly connected to one of the conveyor rollers and can adjust the rotational speed of the conveyor roller when the first sensor detects that the tension roller is in the first position, or when the second sensor detects that the tension roller is in the second position, so that the tension roller is between the first and second positions. This application can improve the efficiency of roll changing for workers.

This invention discloses a PE film production winding device, relating to the field of PE film production technology. It includes a base, with a fixed frame and a mounting seat on both sides of the upper surface of the base. A tension adjustment mechanism is located between the fixed frame and the mounting seat on the base. A pressing and conveying mechanism is located on the fixed frame. A dust adsorption mechanism and two elastic chuck mechanisms are located on the tension adjustment mechanism. A rotating mounting mechanism and a rotating drive mechanism are located on the mounting seat. Several mounting sleeve mechanisms are located on the rotating mounting mechanism. A winding roller mechanism is located on the mounting sleeve mechanism. A limiting wheel mechanism is located on the rotating mounting mechanism. This invention, by setting up a pressing and conveying mechanism, can clamp and convey PE films of different thicknesses. The tension adjustment mechanism can adjust the deflection angle of the two elastic chuck mechanisms, thereby adjusting the winding tension of the film. Combined with the dust adsorption mechanism for dust removal, this improves the efficiency of PE film production winding.
