Description

Technical Field

[0001] The utility model relates to the technical field of film processing, in particular to a film leveling device. Background Art

[0002] With the rapid development of the global economy, the use of aluminum-plastic composite film has also grown rapidly. Aluminum-plastic composite film has good flexibility, moisture resistance, oxygen barrier, light shielding, shielding, anti-static, vacuum-proof, and color printing. It can be used in food, medicine, pesticides, chemicals, electromechanical products, etc.

[0003] For example, a film leveling device with the announcement number "CN211812616U" can absorb the film onto the circumferential side wall of the vacuum roller through dense air holes to form a tensioned state. There is no need to set up a special tension control system for the film, which saves components and energy consumption. The leveling roller evenly flattens the film passing through the gap between the vacuum roller and the leveling roller, so it is not easy to misprint when printing the film. However, the device limits the film in the process of flattening the film. If the film is narrow, the film will deviate during the flattening process, affecting the subsequent collection or processing of the film. At the same time, the film will produce wrinkles during transportation. The device directly flattens and levels the film, which will directly stack and compact the wrinkles produced during transportation, resulting in poor leveling quality of the device.

[0027] Refer to the attached Figure 1-2 and 4-5:

[0030] Working principle:

[0031] When the film needs to be leveled, the film is passed from right to left between the second round roller 405 and the first transverse plate 5, then bypasses the vacuum roller 6 from above the vacuum roller 6, and passes between the first round roller 12 and the vacuum roller 6. The dense air holes of the vacuum roller 6 adsorb the film on the vacuum roller 6, preparing for the film leveling work.

[0032] Distance adjustment operation:

[0033] Connect the external power supply of the first motor 301, start the first motor 301 to drive the first connecting rod 303 to rotate, the rotation of the first connecting rod 303 drives the second connecting rod 304 to move, the movement of the second connecting rod 304 drives the slider 305 to move, the movement of the slider 305 drives the baffle 306 to move, and adjust the distance between the baffles 306 according to the width of the film to prevent the film from shifting during operation.

[0034] The external power supply of the second motor 13 is turned on, and the second motor 13 is started to drive the vacuum roller 6 to rotate. The rotation of the vacuum roller 6 drives the film to move, so that the film passes between the first round roller 12 and the vacuum roller 6, and the first round roller 12 flattens the film.

[0035] Prevent film from folding:

[0036] When the external power supply of the electric telescopic rod 401 is turned on, the output end of the electric telescopic rod 401 extends to drive the Y-shaped block 403 to move, the movement of the Y-shaped block 403 drives the straight rod 406 to move, the movement of the straight rod 406 drives the straight plate 404 to move, and the movement of the straight plate 404 drives the second round roller 405 to move, so that the round roller 405 moves to both sides, stretching the film under the round roller 405 to both ends to prevent the film from stacking before flattening, and then the output end of the electric telescopic rod 401 is controlled to shorten to convey the film to the left. According to the above principle, the electric telescopic rod 401 continues to extend and retract to stretch the film before it is conveyed to the vacuum roller 6.
