[0004] When the existing self-adhesive film covering device is in use, the film will vibrate under the traction force, resulting in uneven self-adhesive film covering. In view of this, we propose a self-adhesive film covering device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a self-adhesive film covering device to solve the problem that the film vibrates under the traction force and the self-adhesive film covering is uneven as mentioned in the above background art.

[0006] In view of this, the present utility model provides a self-adhesive film laminating device, which includes a film laminating frame. One end of the film laminating frame is rotatably connected with a guiding roller. One side of the guiding roller is fixedly connected with a positioning table on the inner wall of the film laminating frame. Above the positioning table is provided a pressing plate. One side of the positioning table is rotatably connected with a first positioning roller. One side of the first positioning roller is rotatably connected with a film laminating roller. Above the film laminating roller is provided an adjusting roller. The top end of the film laminating frame is rotatably connected with a feeding roller. The inner wall of the film laminating frame is fixedly connected with a fine-tuning frame. The top end of the fine-tuning frame is threadedly connected with an adjusting screw rod. The bottom end of the adjusting screw rod is rotatably connected with a positioning plate. A limiting groove is opened at the connecting part of the fine-tuning frame and the positioning plate. The bottom end of the positioning plate is attached to a connecting block which is rotatably connected with one end of the adjusting roller. A spring is fixedly connected at the connecting part of the connecting block and the fine-tuning frame. The bottom end of the connecting block is fixedly connected with a working damper. One side of the film laminating roller is rotatably connected with a second positioning roller;

[0007] A positioning component, which is fixedly connected with the inner wall of the film laminating frame above the pressing plate and is used for adjusting the height of the pressing plate.

[0008] In this technical solution, the adjusting screw rod drives the positioning plate to slide along the inner wall of the limiting groove through the thread. Through the relative position of the positioning plate and the fine-tuning frame, the adjustment operation of the film tension on the outer wall of the adjusting roller is realized. When the film laminating roller works, the film on the outer wall of the feeding roller will vibrate under the traction force. The movement of the film drives the connecting block to overcome the elastic force of the spring through the adjusting roller, converts the vibration caused by the film movement into the elastic potential energy of the spring, and converts the elastic potential energy of the spring into the internal energy of the working damper through the working damper, realizing the stable film laminating operation of the film.

[0009] In the above technical solution, further, the film laminating roller and the adjusting roller are located in the same vertical plane and are parallel to each other.

[0010] In this technical solution, the film is connected with the film laminating roller through the adjusting roller, avoiding uneven film laminating of the self-adhesive workpiece in contact with the film laminating roller caused by film vibration.

[0011] In the above technical solution, further, the adjusting roller and the fine-tuning frame form a lifting structure through the spring and the connecting block, and a guiding groove for sliding connection with the outer wall of the connecting block is opened inside the fine-tuning frame.

[0012] In this technical solution, the adjusting screw rod drives the positioning plate to slide along the inner wall of the limiting groove through the thread. Through the relative position of the positioning plate and the fine-tuning frame, the adjustment operation of the film tension on the outer wall of the adjusting roller is realized.

[0013] In the above technical solution, further, two groups of pressing plates are provided, and the two groups of pressing plates are symmetrical about the film laminating roller.

[0014] In this technical solution, positioning operations are performed on both ends of the self-adhesive film to avoid positioning operations on the self-adhesive workpiece.

[0015] In the above technical solution, further, the pressing plate is parallel to the positioning table.

[0016] In this technical solution, the pressing plate slides to drive the self-adhesive workpiece to fit against the top of the positioning table, realizing the positioning operation of the self-adhesive workpiece.

[0017] In the above technical solution, further, the positioning assembly includes:

[0018] A positioning frame. A positioning frame is fixedly connected to the inner wall of the film covering frame above the pressing plate. A bolt is rotatably connected to the top of the positioning frame. A threaded slider is threadedly connected to the outer wall of the bolt. A connecting frame is fixedly connected to the outer wall of the threaded slider. A connecting rod fixedly connected to the outer wall of the pressing plate is fixedly connected to the bottom end of the connecting frame.

[0019] In this technical solution, the worker rotates the bolt. The bolt drives the connecting frame to slide vertically along the bottom end of the positioning frame through the threaded slider. The sliding of the connecting frame drives the pressing plate on the outer wall of the connecting rod to slide synchronously. The sliding of the pressing plate drives the self-adhesive workpiece to fit against the top of the positioning table, realizing the positioning operation of the self-adhesive workpiece.

[0020] In the above technical solution, further, the pressing plates are equidistantly distributed along the outer wall of the connecting rod.

[0021] In this technical solution, it is beneficial to perform uniform positioning operations on the self-adhesive workpiece.

[0022] The beneficial effects of the present utility model are:

[0023] 1. For this self-adhesive film covering device, by setting the adjusting roller, the adjusting screw drives the positioning plate to slide along the inner wall of the limiting groove through the thread. Through the relative position between the positioning plate and the fine-tuning frame, the adjustment operation of the film tension on the outer wall of the adjusting roller is realized. When the film covering roller is working, the film on the outer wall of the loading roller will vibrate under the traction force. The movement of the film drives the connecting block to move against the elastic force of the spring through the adjusting roller, converting the vibration caused by the film movement into the elastic potential energy of the spring, and converting the elastic potential energy of the spring into the internal energy of the working damper through the working damper, realizing the stable film covering operation of the film.

[0024] 2. For this self-adhesive film covering device, by setting the pressing plate, the worker rotates the bolt. The bolt drives the connecting frame to slide vertically along the bottom end of the positioning frame through the threaded slider. The sliding of the connecting frame drives the pressing plate on the outer wall of the connecting rod to slide synchronously. The sliding of the pressing plate drives the self-adhesive workpiece to fit against the top of the positioning table, realizing the positioning operation of the self-adhesive workpiece.
