Description

Technical Field

[0001] This utility model belongs to the field of unwinding machine technology, and particularly relates to a base unwinding machine for roll material production. Background Technology

[0002] Existing waterproof membranes are divided into reinforced and unreinforced membranes. The reinforcing layer exists inside the waterproof membrane as a reinforcing skeleton to achieve a balance between mechanical properties and waterproof stability. During the production process, the reinforcing layer needs to be unrolled. In the use of existing reinforcing unrolling machines, after feeding, manual alignment of the edges of the reinforcing membrane and clamping and fixing of the reinforcing roll are required, which affects the overall unrolling efficiency. At the same time, during unrolling, excessive radial runout of the rotating shaft can easily occur, causing fluctuations during the unrolling process, resulting in wrinkles and affecting the unrolling effect. Utility Model Content

[0003] This utility model addresses the problems of manual alignment, incomplete clamping, and excessive radial runout in existing technologies for material feeding and clamping, and proposes the following technical solution:

[0005] As a preferred embodiment of the above technical solution, the clamping assembly includes a main shaft rotatably connected to the inner surface of the mounting bracket, a guide round head column fixedly connected to the left end of the main shaft, a first shock absorber fixedly connected to the inner surface of the main shaft, a counterweight bar fixedly connected to the other end of the first shock absorber, a limit bar engaged with the outer surface of the counterweight bar, the outer surfaces of the counterweight bar and the limit bar slidably connected to the inner surface of the main shaft, a guide inclined clamp slidably connected to the inner surface of the main shaft, the right inclined surface of the guide inclined clamp slidably connected to the bottom inclined surface of the counterweight bar, and the inner surface of the guide inclined clamp slidably connected to the outer surface of the guide round head column.

[0006] As a preferred embodiment of the above technical solution, the limiting component includes an L-shaped frame fixedly connected to the left and right ends of the side frame, a linkage arm rotatably connected to the inner end of the L-shaped frame, a roller fixedly connected to the left end of the linkage arm, the outer surface of the roller abutting against the outer surface of the guide round head column, and a second shock absorber fixedly connected to the other end of the linkage arm.

[0007] As a preferred embodiment of the above technical solution, a rotating block is fixedly connected to the other end of the second shock absorber, a third shock absorber is fixedly connected to the inner end of the rotating block, a shaped frame is fixedly connected to the other end of the third shock absorber, a fourth shock absorber is fixedly connected between the opposite surfaces of adjacent shaped frames, a second roller is rotatably connected to the inner end of the shaped frame, and the outer surface of the second roller abuts against the outer surface of the guide round head column.

[0008] As a preferred embodiment of the above technical solution, a side cover is fixedly connected to the left end of the side frame, an electric push rod is fixedly connected to the right end of the side cover, an annular connecting frame is fixedly connected to the output end of the electric push rod, an arc-shaped block is fixedly connected to the right end of the annular connecting frame, and the right end of the arc-shaped block abuts against the left end of the guide inclined clamp.

[0009] As a preferred embodiment of the above technical solution, a ring-shaped side frame is fixedly connected to the left end of the side frame, a multi-stage push rod is fixedly connected to the right end of the ring-shaped side frame, a left limiting plate is fixedly connected to the output end of the multi-stage push rod, a right limiting plate is fixedly connected to the left end of the mounting frame, a second motor is fixedly connected to the right end of the base, a main shaft is fixedly connected to the output end of the second motor, and a guide roller is rotatably connected to the upper end of the base, with the outer surface of the guide roller rotatably connected to the inner surfaces of the left and right limiting plates.

[0010] The beneficial effects of this utility model are as follows:

[0011] By activating the electric push rod, the annular connecting frame and the arc-shaped block abut against the guide inclined clamp, pushing the guide inclined clamp to move inward. At the same time, the arc-shaped block provides auxiliary limit to the main shaft, ensuring the overall coaxiality and stability of the main shaft. Through the cooperation between the guide inclined clamp and the inclined surface of the counterweight bar, when the guide inclined clamp moves to the right, it can drive each counterweight bar and limit bar to move synchronously, which is convenient for clamping and fixing tire base drums of different sizes. The counterweight bar can provide additional radial pressure during rotation, improving the overall clamping stability and reliability, and avoiding slippage that affects the overall unwinding effect.

[0012] By contacting the arc surface of roller one with the guide round head column and limiting the linkage arm of the L-shaped frame, an arc is generated with the contact point between the linkage arm and the L-shaped frame as the center when roller one moves left and right. This drives the irregular frame to move inward and outward under the limitation of the L-shaped frame. When roller one moves to the outermost position, it drives roller two to clamp the guide round head column. The radial runout generated by the rotation of the main shaft is offset by the second and third shock absorbers. That is, through the cooperation of roller one and the linkage arm, the lateral and radial limits of the main shaft can be automatically completed during loading and unloading, improving the overall loading efficiency and stability. At the same time, through the linkage action of the irregular frame and the fourth shock absorber, the various irregular frames can be driven to move synchronously, which facilitates the distribution of the radial force generated by the rotation to the second, third and fourth shock absorbers, improving the overall stability and reliability.

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example 1

[0024] This utility model provides a base unwinding machine for roll material production, such as... Figures 1 to 8As shown, the device includes a base 1, with a mounting bracket 2 fixedly connected to the upper end of the base 1. A clamping assembly 3 is rotatably connected to the inner surface of the mounting bracket 2. The clamping assembly 3 includes a main shaft 301 rotatably connected to the inner surface of the mounting bracket 2. A guide round head post 302 is fixedly connected to the left end of the main shaft 301. A first shock absorber 303 is fixedly connected to the inner surface of the main shaft 301. A counterweight bar 304 is fixedly connected to the other end of the first shock absorber 303. A limit bar 305 is engaged with the outer surface of the counterweight bar 304. The outer surfaces of the counterweight bar 304 and the limit bar 305 slide against the inner surface of the main shaft 301. The main shaft 301 is slidably connected to a guide inclined clamp 306 on its inner surface. The right inclined surface of the guide inclined clamp 306 is slidably connected to the bottom inclined surface of the counterweight bar 304. The inner surface of the guide inclined clamp 306 is slidably connected to the outer surface of the guide round head column 302. A first motor 4 is fixedly connected to the right end of the mounting frame 2. A threaded rod 5 is fixedly connected to the output end of the first motor 4 through the mounting frame 2. A side frame 6 is threadedly connected to the outer surface of the threaded rod 5. The upper end of the side frame 6 is slidably connected to the lower end of the mounting frame 2. When the first motor 4 is started, the threaded rod 5 is driven to rotate, and the rotation is achieved through the threaded rod 5. The threaded drive of the side frame 6 and the limiting effect of the mounting bracket 2 on the side frame 6 cause the side frame 6 to move left and right. The left and right ends of the side frame 6 are fixedly connected to the limiting component 7. The left end of the side frame 6 is fixedly connected to the side cover 8. The right end of the side cover 8 is fixedly connected to the electric push rod 9. The output end of the electric push rod 9 is fixedly connected to the annular connecting frame 10. The right end of the annular connecting frame 10 is fixedly connected to the arc-shaped block 11. The right end of the arc-shaped block 11 abuts against the left end of the guide inclined clamp 306. By activating the electric push rod 9, the annular connecting frame 10 and the arc-shaped block 11 abut against the guide inclined clamp 306, pushing the guide inclined clamp 306. The clamp 306 moves inward, and at the same time, the arc block 11 provides auxiliary limiting for the main shaft 301, ensuring the coaxiality and stability of the main shaft 301 as a whole. Through the cooperation of the inclined guide clamp 306 and the inclined surface of the counterweight bar 304, when the guide inclined clamp 306 moves to the right, it can drive each counterweight bar 304 and the limiting bar 305 to move synchronously, which is convenient for clamping and fixing tire base drums of different sizes. The counterweight of the counterweight bar 304 can provide additional radial pressure during rotation, improve the overall clamping stability and reliability, and avoid slippage that affects the overall unwinding effect.

[0025] like Figures 1 to 8As shown, a ring-shaped side frame 12 is fixedly connected to the left end of the side frame 6, and a multi-stage push rod 13 is fixedly connected to the right end of the ring-shaped side frame 12. A left limiting plate 14 is fixedly connected to the output end of the multi-stage push rod 13. A right limiting plate 15 is fixedly connected to the left end of the mounting frame 2. The left limiting plate 14 and the right limiting plate 15 can limit the side of the base material, ensuring the stability of the unwinding direction, ensuring the edge stability of the unwinding, and avoiding the skewing of the material. A second motor 16 is fixedly connected to the right end of the base 1, and a main shaft 301 is fixedly connected to the output end of the second motor 16. A guide roller 17 is rotatably connected to the upper end of the base 1. The outer surface of the guide roller 17 is flush with the left limiting plate 14. The inner surfaces of the positioning plate 14 and the right limiting plate 15 are rotatably connected. The limiting assembly 7 includes an L-shaped frame 701 fixedly connected to the left and right ends of the side frame 6. A linkage arm 702 is rotatably connected to the inner end of the L-shaped frame 701. A roller 703 is fixedly connected to the left end of the linkage arm 702. The outer surface of the roller 703 abuts against the outer surface of the guide round head column 302. A second shock absorber 704 is fixedly connected to the other end of the linkage arm 702. A rotating block 705 is fixedly connected to the other end of the second shock absorber 704. A third shock absorber 706 is fixedly connected to the inner end of the rotating block 705. A shaped frame 707 is fixedly connected to the other end of the third shock absorber 706. A fourth shock absorber 708 is fixedly connected between the opposing surfaces of adjacent irregular-shaped frames 707. A second roller 709 is rotatably connected to the inner end of the irregular-shaped frame 707. The outer surface of the second roller 709 abuts against the outer surface of the guide round head column 302. Through the contact between the first roller 703 and the arc surface of the guide round head column 302 and the limitation of the linkage arm 702 by the L-shaped frame 701, an arc can be generated with the contact point between the linkage arm 702 and the L-shaped frame 701 as the center when the first roller 703 moves left and right. This drives the irregular-shaped frame 707 to move inward and outward under the limitation of the L-shaped frame 701, so that when the first roller 703 moves to the outermost position, it drives the second roller 709 to move inward and outward. The round-headed column 302 clamps the spindle, and the radial runout generated by the rotation of the main shaft 301 is counteracted by the second shock absorber 704 and the third shock absorber 706. That is, through the cooperation of the roller 703 and the linkage arm 702, the lateral and radial limits of the main shaft 301 can be automatically completed during loading and unloading, improving the overall loading efficiency and stability. At the same time, through the linkage action of the irregular frame 707 and the fourth shock absorber 708, the irregular frame 707 can be driven to move synchronously, which facilitates the distribution of the radial force generated by rotation to the second shock absorber 704, the third shock absorber 706 and the fourth shock absorber 708, improving the overall stability and reliability.

[0026] Working principle: The first motor 4 is started, driving the threaded rod 5 to rotate. Through the threaded transmission between the threaded rod 5 and the side frame 6, and the limiting effect of the mounting bracket 2 on the side frame 6, the side frame 6 is moved to the farthest point to the left. This releases the left-end limit of the clamping assembly 3 by the side frame 6 and the limiting component 7. The base material is then initially fed onto the guide round head post 302. The first motor 4 is started again, driving the side frame 6 and the limiting component 7 to complete the left-end limit of the clamping assembly 3. Through the arc surface contact between the roller 703 and the guide round head post 302, and the limiting effect of the L-shaped frame 701 on the linkage arm 702, a linkage is generated when the roller 703 moves left and right. The contact point between the boom 702 and the L-shaped frame 701 is an arc centered on a circle, thereby driving the irregular frame 707 to move inward and outward under the limitation of the L-shaped frame 701. This facilitates the movement of the roller 703 to the outermost position, causing the roller 709 to clamp the guide round head column 302. The radial runout generated by the rotation of the main shaft 301 is offset by the second shock absorber 704 and the third shock absorber 706. In other words, through the cooperation of the roller 703 and the boom 702, the lateral and radial limits of the main shaft 301 can be automatically completed during loading and unloading, improving the overall loading efficiency and stability. The multi-stage push rod 13 is activated, driving the left limit plate 1. 4. Push the tire base roll against the right limiting plate 15 to complete the lateral limiting of the tire base roll. Activate the electric push rod 9 to drive the annular connecting frame 10 and the arc-shaped block 11 to abut against the guide inclined clamp 306, pushing the guide inclined clamp 306 inward. At the same time, the arc-shaped block 11 provides auxiliary limiting for the main shaft 301, ensuring the overall coaxiality and stability of the main shaft 301. Through the inclined surface cooperation between the guide inclined clamp 306 and the counterweight bar 304, when the guide inclined clamp 306 moves to the right, it can drive each counterweight bar 304 and the limiting bar 305 to move synchronously, facilitating the clamping and fixing of tire base rolls of different sizes. The counterweight provides additional radial pressure during rotation, improving the overall clamping stability and reliability, and preventing slippage that could affect the overall unwinding effect. The head end of the base material roll is routed around the guide roller 17 and connected to the external processing device. The second motor 16 is started to drive the clamping assembly 3 to rotate and unwind. Through the linkage of the irregular frame 707 and the fourth shock absorber 708, the irregular frames 707 can be moved synchronously, which facilitates the distribution of the radial force generated by rotation to the second shock absorber 704, the third shock absorber 706 and the fourth shock absorber 708, thereby improving the overall stability and reliability.
