Description

Technical Field

[0001] The present invention belongs to the technical field of the production of coiled materials, and particularly relates to a coreless automatic winding device for waterproof membranes and a winding method for waterproof membranes. Background Art

[0002] An automatic winder is the winding part of a coiled material processing production line and is widely used in processing production lines such as paper rolls, cloth rolls, plastic rolls, and metal coiled materials. At present, a new type of polymer waterproof membrane material (hereinafter referred to as waterproof membrane) has been invented, which is applicable to various tunnel and underground space waterproof projects.

[0003] It is difficult to automatically wind the waterproof membrane using the traditional winding method: one side of the waterproof membrane material is a smooth surface, and the other side is sprayed with granular materials, and there is a phenomenon of slag falling during the production process. Its hardness is also harder than paper, cloth, and plastic, the surface is smoother, and the adsorption and plasticity are poorer.

[0004] The existing automatic winders for waterproof membranes use manual-assisted semi-automatic winding, which has problems such as low work efficiency, high labor intensity, and great potential safety hazards.

[0005] In summary, there is an urgent need to provide a coreless automatic winding device for waterproof membranes and a winding method for waterproof membranes that can improve production efficiency and reduce labor intensity. Summary of the Invention

[0006] The purpose of the present invention is to provide a coreless automatic winding device for waterproof membranes and a winding method for waterproof membranes that can improve production efficiency and reduce labor intensity.

[0082] The present invention also provides a winding method for a waterproof film. The embodiments are as follows: Using the above-mentioned automatic winding device for a waterproof film without a core for winding, including the following steps:

[0083] (1) The air shaft 301 rotates to a specified angle, and the second driving member 703 and the third driving member respectively drive the lower guide plate 705 and the upper guide block 706 to extend to the opening position of the fixed piece 310 of the winding mechanism 3. The lower guide plate 705 and the upper guide block 706 form an included angle channel to ensure that the head of the waterproof film is sent to the specified position of the air shaft 301;

[0084] Specifically, the waterproof film is placed between the upper roller 401 and the lower roller 411 of the feeding mechanism 4. The upper roller 401 presses down and compresses the waterproof film. The lower roller 411 rotates forward under the action of the feeding driving member 408 to convey the waterproof film. When the head of the waterproof film reaches between the air shaft 301 and the fixed piece 310, the feeding stops and waits for the next action.

[0085] (2) The feeding mechanism 4 conveys the head of the waterproof film to the predetermined position of the air shaft 301;

[0086] (3) The air shaft 301 is inflated, the key strip ejects to clamp the head, and at the same time, the movable piece 309 also ejects. The first driving member drives the air shaft 301 to rotate, so as to wind the waterproof film on the fixed piece 310 and the movable piece 309, fix the head of the waterproof film, and then the lower guide plate 705 and the upper guide block 706 retract, and the air shaft 301 rotates for winding;

[0087] Specifically, before the feeding mechanism 4 feeds, the lower guide plate 705 is rotated to the opening position of the fixed piece 310 in the winding mechanism 3 by the extending action of the second driving member 703, and the upper guide block 706 is rotated to the opening position of the fixed piece 310 in the winding mechanism 3 by the extending action of the second cylinder. The lower guide plate 705 and the upper guide block 706 form an included angle channel to ensure that the head is sent to the specified position of the air shaft 301.

[0088] (4) After winding a certain length, the air shaft 301 stops rotating. The taping mechanism 2 tapes the adhesive piece, presses the adhesive side of the tape on the rolled material, the upper pressing plate 511 presses down and compresses the waterproof film, the cutting mechanism 5 cuts the waterproof film, the upper pressing plate 511 moves up to relax, and the air shaft 301 rotates to complete the winding of the remaining waterproof film;

[0089] During the specific operation, before the coiling material is completely coiled, the vertical driving member 216 (elevator) drives the vertical moving frame 211 to move upward, pressing the adhesive side of the tape onto the coiling material. The coiling motor 305 drives the air shaft 301 to rotate, and the tape winds around the coiling material to paste and fix the coiling material. The vertical driving member 216 drives the vertical moving frame 211 to move downward for a certain stroke and stop. The glue cutting driving member 206 drives the tool rest 202 to rotate and cut the tape. The vertical moving frame moves downward to the lowest point and waits for the next operation. When the winding length of the waterproof film reaches the target number, the air shaft 301 stops rotating. The tape sticking mechanism 2 moves upward and presses tightly to stick the tape to the outer circle of the coiling material. The upper pressing plate 511 presses downward and presses the waterproof film tightly. The cutting motor 506 drives the cutting film blade 501 to move linearly, and the blade cuts the waterproof film. The upper pressing plate 511 moves upward to relax. The air shaft 301 rotates to complete the winding of the remaining waterproof film. At the same time, the operation of sticking a circle of tape to the outer circle of the coiling material is completed to fix the coiling material.

[0090] (5) The air shaft 301 rotates, and the tape sticking member winds the tape around the coiling material to paste and fix the coiling material, completing the operation of sticking a circle of tape to the outer circle of the coiling material. Then, the glue cutting member cuts the tape, and the air shaft 301 stops rotating;

[0091] (6) The discharging mechanism 6 pushes out the coiling material for discharging. The discharging motor 606 drives the main sprocket 605 to rotate, so that the pushing member 601 moves linearly left and right to achieve the discharging function.

[0092] The above is only the preferred embodiment of the present invention.
