Description

Technical Field

[0001] The invention relates to the technical field of film processing, in particular to a backrest type preparation shaft pre-rolling device. Background Art

[0002] Film winding is a machine that winds the film into a roll on the winding drum through the rotation of the winding drum. The purpose of this machine is to facilitate the transportation and storage of the film. It is often used at the end of the film production line. When the existing device is winding the film, the winding speed will be slowed down at the end of the winding so that the rotating roller can be removed from the machine.

[0003] However, when the film is wound up after the speed slows down, the end of the film may not fit tightly on the rotating roller after the film is cut, resulting in bubbles between the films or looseness between the end of the film and the rotating roller, affecting the subsequent use of the film. Summary of the invention

[0008] Furthermore, each of the bearing lifting mechanisms includes a slide rail, a slider, a mounting plate, a lifting cylinder and a placement seat. The slide rail is vertically arranged on the side wall of the mounting seat, the slider slides in cooperation with the slide rail, the mounting plate is horizontally arranged on the top of the slide rail, the lifting cylinder is located on the top of the mounting plate and the telescopic end of the lifting cylinder is connected to the top of the slider, and the placement seat is fixedly connected to the slider.

[0010] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0011] Firstly, before the film is rolled up, the two bearing lifting mechanisms of the present invention drive the inflatable shaft to move to the best rolling position, and the two bearing fixing mechanisms fix and limit the position of the inflatable shaft to prevent the position of the inflatable shaft from shifting during the film rolling process. Before the film on the inflatable shaft is nearly finished rolling up, the positioning approaching mechanism works to approach the position of the inflatable shaft. When the positioning approaching mechanism contacts the inflatable shaft, the transmission mechanism works to drive the inflatable shaft to rotate, so that when the rolling work is nearly completed, the end of the film and the film roll on the inflatable shaft are precisely attached to the film roll by electrostatic conduction, thereby preventing bubbles and unevenness between the end of the film and the film roll after rolling up, which affects subsequent use.

[0012] Secondly, before the film on the inflatable shaft is nearly finished being rolled up, the telescopic end of the driving electric cylinder drives the proximity plate to rotate through the rotating shaft, moves the position of the proximity plate toward the position of the inflatable shaft, and makes the position of the rubber wheel on the top of the proximity plate contact with the inflatable shaft, so that the subsequent rubber wheel drives the inflatable shaft to rotate, thereby achieving accurate rolling of the end of the film.

[0013] Thirdly, when the driving electric cylinder drives the rubber wheel to contact the inflatable shaft, the proximity switch senses the position of the rubber wheel and transmits a signal to the controller. The controller controls the driving electric cylinder to stop working and controls the transmission motor to work. The transmission motor drives the rubber wheel to rotate through the connecting belt and the transmission belt. The rotation of the rubber wheel drives the inflatable shaft to rotate on two bearing lifting mechanisms and two bearing fixing mechanisms, so that when the winding work is nearly completed, the end of the film and the film roll on the inflatable shaft are precisely bonded to the film roll through electrostatic conduction, thereby preventing bubbles and unevenness between the end of the film and the film roll after winding, affecting subsequent use.

Before the film on the inflatable shaft 6 is almost finished rolling up, the positioning approaching mechanism 3 works to approach the position of the inflatable shaft 6. When the positioning approaching mechanism 3 contacts the inflatable shaft 6, the transmission mechanism 2 works to drive the inflatable shaft 6 to rotate, so that when the rolling work is almost finished, the end of the film and the film roll on the inflatable shaft 6 are precisely attached to the film roll through electrostatic conduction, thereby preventing bubbles and unevenness between the end of the film and the film roll after rolling up, which affects subsequent use.

After the position is adjusted, the automatic locker 53 locks the two ends of the inflatable shaft 6;

[0027] Before the film on the inflatable shaft 6 is nearly finished winding, the telescopic end of the driving electric cylinder 33 drives the proximity plate 32 to rotate through the rotating shaft 31, and moves the position of the proximity plate 32 toward the position of the inflatable shaft 6.
