Description

Technical Field

[0001] The present application relates to the technical field of roll material winding and unwinding, and more specifically, to a cloth unwinding device for non-stop material change and a method for using the same. Background Art

[0002] The non-stop cloth unwinding device for changing material is a specially designed film processing mechanical device. It is used to continuously provide film and automatically complete the roll changing operation without stopping the main machine during the production process. Its core is to realize the two major functions of "non-stop" and "automatic roll changing". When the main material roll is about to run out, it needs to be unwound, and the starting end of the spare material roll is automatically connected to the end of the main material roll. Usually, manual tape is pasted on the connection to make the old material and the new material adhere, so that the spare unwinding shaft starts to drive the spare material roll to rotate, and the film continues to be conveyed to the downstream process at a constant tension and speed. After the new roll is started, the system will gradually restore the unwinding speed to normal levels to ensure the continuity and stability of the film. For example, the patent announcement number CN210236548U records a non-stop quick-connect material changing and unwinding mechanism. The mother roll is pushed out of the unwinding position, and the new roll of the roll storage device is slowly placed into the unwinding position by the hydraulic cylinder. The main rewinding unit will continue production without stopping. After the new roll is in place, the paper head is perfectly adhered to the paper of the working mother roll through the adhesion of double-sided tape, completing the non-stop roll changing function.

[0003] However, manual pasting requires human intervention and cannot achieve fully automated production, which limits the overall automation level of the production line and affects the production rhythm. In addition, it is difficult to maintain consistent strength and angle of manual pasting, which can easily cause the tape to fall off. It is also difficult for humans to accurately control the position of the tape, which can easily lead to uneven joints and affect subsequent processes.

[0004] Therefore, in order to solve the above problems, a non-stop cloth unwinding device for changing materials and a method for using the same are proposed. Summary of the Invention

10. A method for using a cloth unwinding device for non-stop material change, using the cloth unwinding device for non-stop material change according to claims 1-9, characterized in that: The method of use comprises the following steps: Step 1: Place the spare film roll (2) on the roll changing machine (1), and then temporarily store a certain amount of film (11) on the storage rack (13) to buffer the speed difference between the main unwinding shaft and the spare unwinding shaft to ensure a smooth roll changing process; Step 2: By starting the third electric push rod (901) and the fourth electric push rod (904), the second pressing plate (902) and the third pressing plate (905) are driven to move downward, so that the film (11) is fixed on the processing table (3), and then the film (11) is cut by the cutting knife (15); Step 3: Restart the grabbing mechanism (5) to move the film (11) at the starting end of the spare film roll (2) onto the processing table (3), so that the film on the spare film roll (2) and the cut film are placed together and the two are placed flush; Step 4: Open the baffle (708), place multiple sets of connecting films (707) in the card slot (706), start the hydraulic rod (702) to drive the storage bin (703) to be inserted into the connecting frame (604), and then start the drive motor (602) to drive the first threaded rod (603) to rotate, so that the connecting frame (604) moves downward. When the connecting frame (604) moves downward, the gluing mechanism (10) is operated to apply glue to the bottom of the connecting film (707) through the gluing roller (1008), and the grabbing mechanism (5) is loosened and removed from the film (11); Step 5: When the connecting frame (604) moves to the top of the film (11), the glue roller (1008) completes its work, and then the hydraulic rod (702) is started to drive the storage bin (703) to move down, so that the storage bin (703) presses the film (11), and then the second electric push rod (704) is started to drive the first pressure plate (705) to move down, so that the glue-coated connecting film (707) is moved out of the card slot (706), and then the connecting film (707) is bonded to the two groups of films (11) so as to fix the two groups of films (11) together. Then the device for fixing the film (11) is removed, and the spare unwinding shaft starts to drive the spare film roll (2) to rotate. The film (11) continues to be transported to the downstream process at a constant tension and speed. After the new roll is started, the system will gradually restore the unwinding speed to a normal level to ensure the continuity and stability of the film (11).
