Description
Technical Field
[0001] The utility model relates to the technical field of slitting and winding equipment, in particular to an improved structure of a slitting and winding roller arm. Background Art
[0002] Slitting and rewinding is an industrial process used to slit large rolls of material into smaller rolls of varying widths. This process typically involves unwinding, pulling, slitting, and rewinding. The pressure roller arm is a crucial auxiliary component in the slitting and rewinding process, ensuring smoothness and uniformity of the material during rewinding, preventing wrinkling or deformation. Compared to traditional pressure roller arms, those equipped with electric cylinders have a faster response time, allowing for quick adjustments to the position and pressure of the roller arm.
[0003] However, existing slitting and rewinding equipment often fails to automatically adjust the gap between the rollers as the roll diameter increases during the rewinding process. This is because the change in roll diameter causes a change in the contact pressure between the material and the rollers. If the gap between the rollers cannot be adjusted accordingly, the material may rewind unevenly, or even wrinkle or sag.
[0004] Therefore, during the winding process of the rollers, the spacing between them needs to be adaptively adjusted.
[0005] In view of the above problems, it is urgent to carry out innovative design based on the original pressure roller arm. Utility Model Content

If the pressure plate and the piston pressure plate are closer, the force required for the winding material to act on the second pressure roller frame to move into the support cylinder will increase. Similarly, it can be flexibly changed according to different materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Working principle: According to Figure 1As shown, during slitting and rewinding, the motor drives the rewinding roller 3 to rotate for the rewinding operation. As the rewinding roller 3 rotates one circle, the diameter of the rewinding shaft will gradually increase. With each rotation of the rewinding roller 3, the convex gear 401 will be driven to rotate one circle at the same time. Through the tooth block on its upper part, the gear rod 402 will be periodically driven to move downward. The movable plate 403 cooperates with the fixed plate 405 to compress the return spring 404, and cooperates with the connecting rod 505 to press and trigger the power structure 5 to work. As the connecting rod 505 pushes the piston plate 502 to move in the cylinder 501, the piston plate 502 is pushed down. 02 moves downward, the cover plate 504 in the opening 503 will close, and the hydraulic oil in the cylinder body 501 below the piston plate 502 will be pressed into the branch groove 506. At the same time, the negative pressure will draw the hydraulic oil in the water tank 511 into the cylinder body 501 above the piston plate 502 through the output pipe 512. When the return spring 404 drives the connecting rod 505 and the piston plate 502 to move upward and reset, the opening 503 and the cover plate 504 will open, so that the hydraulic oil above the piston plate 502 in the cylinder body 501 flows to the bottom of the piston plate 502, making it easier to drive into the branch groove 506 next time.
[0028] After entering the branch groove 506, the hydraulic oil flows into the chute 507 and the vertical groove 514 respectively. The flow into the chute 507 pushes the slider 508 to move, driving the mounting frame 6, the electric cylinder structure 7 and the first pressure roller frame 8 to move outward, thereby coordinating with the continuous increase in the diameter of the winding shaft, ensuring that the first pressure roller frame 8 always fits the outer wall of the winding. At the same time, the branch groove 506 transports the hydraulic oil to the vertical groove 514 through the pipe 513, pushing the movable block 515 to move upward, causing the pressure structure 9 and the second pressure roller frame 10 connected to the movable block 515 to move upward, coordinating with the continuous increase in the diameter of the winding shaft;
[0029] In addition, by rotating the screw 903, the distance between the pressure plate 904 and the piston pressure plate 906 is changed, so that the pressure spring 905 is compressed to a certain extent, thereby changing the force required for the hydraulic oil in the box 901 to push the piston pressure plate 906. This is the working principle of the improved structure of the slitting and winding roller arm.
