Technical Field
[0001] The utility model belongs to the field of film production equipment, in particular to an automatic film adhesive tape device. Background Art
[0002] With the advancement of science and technology and the improvement of people's living standards, more and more films are used in industrial production and people's daily lives. These products have brought great convenience to industrial production and people's lives. Before use, the film often needs to be cut to meet the width requirements of use. Under the existing slitting method, after the film is cut according to the width requirements and rolled according to the length requirements, it is often necessary to help fix the tail end of the roll formed after rolling to prevent the film from loosening from the end. However, this method requires special personnel to supervise and handle, which is time-consuming and labor-intensive. Moreover, when there are many film strips cut out at one time or multiple rolls are rolled at the same time, it is easy for personnel to not have time to fix the tail of each roll of film in time, which will cause some rolls to become loose while waiting for fixation, affecting the quality of rolling, and seriously affecting the use and causing waste. For this reason, people hope to find a better way to fix the tail end of the film roll. Utility Model Content
[0003] The utility model aims to provide an automatic film adhesive tape device, wherein the adhesive tape is used to automatically adhere and fix the tail of the film on the film roll when the film is rolled up, so that the film roll will not loosen.
[0004] The utility model is realized by the following technical solutions:
[0005] The film automatic adhesive tape device is used to be arranged between the unwinding device and the winding device. A film slitting device is also arranged between the film automatic adhesive tape device and the winding device. The film automatic adhesive tape device includes a double-sided adhesive unwinding roller, a release layer winding roller, a release layer peeling guide roller, a tape pressing roller, a driving unit for driving the tape pressing roller to press down, a tape cutting knife, a tape transfer roller and a film guide roller. The double-sided adhesive unwinding roller, the release layer winding roller, the release layer peeling guide roller, the tape pressing roller, the driving unit for driving the tape pressing roller to press down and the tape cutting knife are all arranged on a tape unwinding rack. The tape unwinding rack is connected to a device which is arranged on a linear guide rail and can be moved leftward relative to the linear guide rail. The right movable slider is fixedly connected; the linear guide rail is located parallel to the tape transfer roller; the tape transfer roller is driven to rotate by a motor, and an arc-shaped protrusion is provided on the roller surface of the tape transfer roller along the axial direction, except that the outer surface of the arc-shaped protrusion can contact with the film guide roller, the roller surface of the rest of the tape transfer roller cannot contact with the film guide roller, and when the tape pressing roller is driven downward by the driving unit that drives the tape pressing roller to press down, the tape pressing roller can contact with the outer surface of the arc-shaped protrusion on the tape transfer roller; the tape cutting knife is arranged next to the tape pressing roller and can move up and down relative to the tape unwinding rack to facilitate cutting.
[0006] Preferably, a meter is provided on the unwinding device so that the system can control the pressing timing of the tape pressure roller and the rotation timing of the tape transfer roller to complete the transfer of the tape to the film at an appropriate time.
[0007] Preferably, the linear guide rail is arranged on a fixed frame, and the tape transfer roller and the film guide roller are also mounted on the fixed frame.
[0008] Preferably, the tape transfer roller is a non-stick Teflon roller.
[0009] Preferably, the slider is driven by a worm gear drive structure.
[0010] Preferably, the double-sided tape unwinding roller is provided with a damping device to prevent the tape from being unwound excessively.
[0011] Preferably, the driving unit for driving the tape pressure roller to press down includes a gear driven by a motor, and the tape pressure roller is arranged on a base plate that can rotate relative to the tape unloading rack. A transmission gear that meshes with the gear is also fixedly arranged on the base plate. When the tape pressure roller needs to be pressed down, the gear is driven by the motor to rotate, and then the base plate and the tape pressure roller arranged on the base plate are driven to rotate relative to the tape unloading rack through the transmission gear, thereby completing the downward pressure.
[0012] The automatic film tape sticking device is arranged between the unwinding device and the winding device, and is used to stick the glue part of the double-sided tape on the required film length position and required film surface as required, so that after the film is rolled up to the required length after slitting, the tail of the film will automatically adhere to the film roll under the action of the inertial force of winding because of the presence of the pre-sticked double-sided tape glue part, so as to prevent the film roll from loosening. Specifically:
[0013] The double-sided adhesive tape is unwound by the double-sided adhesive unwinding roller and reaches the release layer stripping guide roller. The release layer and the tape layer of the double-sided adhesive tape are separated at the release layer stripping guide roller. The release layer is rolled up by the release layer winding roller, and the tape layer is continuously guided forward to the tape pressing roller. When the tape pressing roller is driven by the driving unit that drives the tape pressing roller to press downward and presses downward toward the tape transfer roller, the tape can be attached to the arc-shaped protrusion of the tape transfer roller. When the attached length is sufficient, the tape pressing roller is retracted upward, and the tape cutting knife moves downward to cut the tape. When multiple sections of tape need to be attached to the tape transfer roller, the tape unwinding rack is moved horizontally above the tape transfer roller along the linear guide rail, and the above process is repeated, thereby enabling multiple sections of tape to be attached to the same side of the tape transfer roller.
[0014] Before transferring the tape, the arc-shaped protrusion on the tape transfer roller faces the tape pressing roller. After the tape pressing roller presses the tape onto the arc-shaped protrusion, when the tape needs to be transferred to the film, the arc-shaped protrusion on the tape transfer roller is driven by the motor to turn to the film guide roller on which the film is guided, and the tape is transferred to the film by continuing to rotate; after the tape transfer is completed, the tape transfer roller rotates again to the position where the arc-shaped protrusion on the tape transfer roller faces the tape pressing roller, waiting for the next tape application and transfer. The tape is used to fix the tail of the film to the film roll at the end of film winding.
