Description

Technical Field

[0001] The utility model relates to the field of cast film winders, in particular to a cast film winder with an adjustment function. Background Art

[0002] At present, in the cast film technology production line, winding is the last process, which is to collect the produced cast film by winding it up. The general working principle is: the motor rotates the winding roller on the winder to wind and collect the cast film on the winding roller, and at the same time, the feeding device on the production line will feed the cast film toward the winder.

[0003] After searching, the Chinese patent with announcement number: CN206940014U discloses a cast film winder, including a first support frame, a winding roller is horizontally arranged on the first support frame, and a first driving mechanism for driving the winding roller to rotate is arranged on one side of the first support frame; a second support frame is arranged opposite to the first support frame, and a pressure roller is arranged in parallel on the side of the winding roller opposite to the second support frame, and the pressure roller is horizontally slidably arranged on the second support frame; a second driving mechanism for driving the pressure roller to move is arranged on the second support frame; a measuring device for measuring the thickness of the cast film on the winding roller is also arranged on the first support frame; the second driving mechanism and the measuring device are both electrically connected to the controller, and the controller controls the second driving mechanism to work according to the measurement data output by the measuring device to adjust the horizontal position of the pressure roller. The utility model can adjust the distance between the pressure roller and the winding roller according to the thickness of the cast film on the winding roller.

[0004] The specific usage and function of the above patent mentions that "a linear displacement sensor for detecting the displacement of the cross plate is also provided at the bottom of the first support frame. The linear displacement sensor is electrically connected to the controller. One end of the linear displacement sensor is vertically connected to the cross plate. When the cross plate is displaced, the measuring rod of the linear displacement sensor can be displaced accordingly. Therefore, the linear displacement sensor can accurately measure the displacement of the cross plate and send the detection value to the controller. After receiving the detection value, the controller will control the second motor to rotate a certain angle, so that the displacement of the pressure roller on the screw rod is equal to the displacement of the cross plate, and then the pressure roller can make corresponding adjustments according to the change in the thickness of the cast film without pressing too tightly on the cast film." However, the above-mentioned pressure roller is a single round rod, which may be difficult to adapt to the unevenness and changes of the surface of the cast film during actual use. If the thickness of the film is uneven, the round rod may apply too much pressure in some areas and too little pressure in other areas, resulting in inconsistency between the thin part and the thick part. For this reason, in view of the above problems, a cast film winder with an adjustment function is proposed to solve the above problems. Utility Model Content
