Description

Technical Field

[0001] This utility model relates to the field of pneumatic constant tension control technology for metal strip, and in particular to a pneumatic constant tension winding control device for metal strip winding machines. Background Technology

[0002] Tension control during the winding process of metal strip is crucial for ensuring winding quality and preventing problems such as loose winding, deviation, and strip breakage. Pneumatic constant tension control is a technology that uses an air pressure regulation system to maintain a constant tension in the roll material (such as paper, film, yarn, etc.) during winding and unwinding. Its core principle is to use a pneumatic brake or cylinder to output adjustable resistance or thrust to counteract tension fluctuations caused by changes in roll diameter, thus achieving closed-loop or open-loop control.

[0003] Existing pneumatic constant tension control devices typically use cylinders to extend and retract the guide rollers, adjusting resistance or thrust. However, in actual use, these devices need to be used in conjunction with metal strip coilers, and cannot be quickly connected between metal strip coilers, affecting overall efficiency. Therefore, we propose a pneumatic constant tension coiling control device for metal strip coilers. Utility Model Content

[0033] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0034] Example:

[0035] like Figures 1-4 As shown, a pneumatic constant tension winding control device for a metal strip winding machine includes:

[0036] Mounting base 1, with swivel wheels symmetrically positioned at its bottom;

[0037] The quick-installation mechanism 2 is fixedly welded to one side of the mounting base 1;

[0038] The connecting and stabilizing mechanism 3 is bolted to the front end of the mounting base 1 and is located on the side close to the quick-release mechanism 2;

[0039] The connecting guide mechanism 4 is symmetrically mounted on the inner side of the mounting base 1 via bolts;

[0040] The threaded rod 5 is fixed and is symmetrically arranged on the rear surface of the mounting base 1;

[0041] The push-pull adjustment mechanism 6 is movably sleeved on the outer surface of the fixed threaded rod 5 and is connected and fastened by a nut.

[0042] The working principle of the above technical solution is as follows:

[0043] During use, the entire unit is first moved to one side of the metal strip winding machine. Then, the internal components of the quick-release mechanism 2 are welded and fixed to the winding machine. At this time, the end of the metal strip is passed between the connecting guide mechanism 4 and the push-pull adjustment mechanism 6, so that the metal strip is in a W shape. Finally, the metal strip is connected and fixed to the winding machine, and the metal strip is wound up. During the winding process, the tension of the metal strip can be adjusted by the push-pull adjustment mechanism 6 to ensure stable winding of the metal strip. The operation is convenient and quick.

[0044] In another embodiment, such as Figure 2 As shown, the quick-installation mechanism 2 includes a connecting block 21 welded to one side of the mounting base 1. A first limiting block 22 and a second limiting block 23 are movably connected to the outer sides of the upper and lower surfaces of the connecting block 21. A connecting limiting frame 24 is fixedly connected to the front end of the second limiting block 23. The first limiting block 22 and the second limiting block 23 are welded to one side of the metal strip winding machine.

[0045] After the first limiting block 22 and the second limiting block 23 are welded and fixed to the winding machine, the entire assembly can be moved under the action of the casters during subsequent installation. This allows the mounting base 1 to move the connecting plug 21, which is then inserted into the inner side of the first limiting block 22 and the second limiting block 23. The connecting stabilizing mechanism 3 is then adjusted. When the connecting plug 21 is fully inserted between the first limiting block 22 and the second limiting block 23, the connecting stabilizing mechanism 3 is reset, allowing it to connect and cooperate with the connecting limiting frame 24 for connection limiting and stable connection. The operation is convenient and quick.

[0046] In another embodiment, such as Figure 2 As shown, the connecting and stabilizing mechanism 3 includes a first leg 31 that is bolted to the mounting base 1. A connecting mounting block 32 is fixedly connected to the end of the first leg 31. A fixing groove 33 is provided on the inner side of the connecting mounting block 32. A movable connecting block 34 is movably connected to the inner side of the fixing groove 33. A connecting latch 35 is fixedly connected to one end of the movable connecting block 34. A connecting actuating block 36 is fixedly connected to the upper part of the front surface of the connecting latch 35.

[0047] This facilitates the movement of the connecting toggle block 36, which in turn moves the connecting clip block 35 and the movable connecting block 34, allowing the movable connecting block 34 to move inside the fixed groove 33 for stable adjustment. The operation is convenient and quick.

[0048] In another embodiment, such as Figure 2 As shown, the outer side of the bottom surface of the connecting block 35 is in contact with the inner side of the connecting limit frame 24, and the outer side of the surface of the movable connecting block 34 is in contact with the inner side of the fixing groove 33.

[0049] The bottom of the connecting block 35 can be stably engaged inside the connecting limit frame 24, while the movable connecting block 34 can move stably inside the fixed groove 33, making the operation convenient and quick.

[0050] In another embodiment, such as Figure 3 As shown, the connecting guide mechanism 4 includes a second support leg 41 bolted to the mounting base 1. One end of the second support leg 41 is fixedly connected to a connecting frame 42. The inner side of the connecting frame 42 is symmetrically and movably connected to a movable connecting end roller 43. The inner side of the movable connecting end roller 43 is fixedly connected to a first guide roller 44. A connecting support partition plate 45 is movably connected between adjacent movable connecting end rollers 43. A fixed actuating block 46 is fixedly connected to the middle of one side of the connecting support partition plate 45. A movable limiting block 47 is movably connected to the inner side of the connecting frame 42. A third support leg 48 is symmetrically provided at the top of the movable limiting block 47. A fixed handle 49 is fixedly connected to the top of the movable limiting block 47.

[0051] The connecting support partition plate 45 can separate the movable connecting end rollers 43. At the same time, when the movable limiting block 47 is inserted into the inner side of the end of the connecting frame 42, it is connected and fixed to the top of the mounting base 1 by bolts through the third support leg 48. This allows the movable connecting end roller 43 to rotate stably between the connecting support partition plate 45 and the movable limiting block 47 and between the connecting support partition plate 45 and the inner side of the connecting frame 42, driving the first guide roller 44 to rotate stably and guide the metal strip.

[0052] In another embodiment, such as Figure 3 As shown, the upper and lower ends of the connecting support partition plate 45 are in contact with the edge of the movable connecting end roller 43, the outer surface of the connecting support partition plate 45 is in contact with the inner side of the connecting frame 42, and the bottom end of the movable limiting block 47 is in contact with the outer edge of the movable connecting end roller 43.

[0053] This allows the connecting support partition plate 45 and the movable limiting block 47 to be stably positioned inside the connecting frame 42, while the movable connecting end roller 43 can rotate stably inside the end of the connecting support partition plate 45, making operation convenient.

[0054] In another embodiment, such as Figure 4 As shown, the push-pull adjustment mechanism 6 includes a connecting mounting plate 61 sleeved on the outer side of the fixed threaded rod 5. A connecting cylinder 62 is fixedly connected inside the connecting mounting plate 61. A connecting end frame 63 is fixedly connected to the output end of the connecting cylinder 62. A second guide roller 64 is movably connected to the inner side of the connecting end frame 63 through a connecting shaft. A pressure sensor is provided between the inner side of the connecting end frame 63 and the connecting shaft inside the second guide roller 64. The connecting cylinder 62 is connected to the controller through a connecting wire harness. The connecting cylinder 62 is connected to an external air pump through a pipe.

[0055] The connecting cylinder 62 can push and pull the connecting end frame 63 and the second guide roller 64, so that the second guide roller 64 can tension or relax the metal strip, thereby adjusting the tension of the metal strip, which facilitates the winding machine to wind the metal strip and makes the operation convenient.

[0056] The working principle of this utility model is as follows: First, the entire assembly is completed, with the first limiting block 22 and the second limiting block 23 welded to the winding machine. Then, when connecting the assembly to the metal strip winding machine, the connecting actuating block 36 is pulled upwards, causing the connecting locking block 35 and the movable connecting block 34 to move. This allows the movable connecting block 34 to move stably within the fixed groove 33. Next, the connecting insert 21 is inserted into the inner sides of the first limiting block 22 and the second limiting block 23. When the connecting insert 21 is fully inserted into the inner sides of the first limiting block 22 and the second limiting block 23, the connecting actuating block 36 is released, allowing the connecting locking block 35 and the movable connecting block 34 to move stably within the fixed groove 33. The connecting block 34 moves downward, allowing the bottom end of the connecting clip 35 to insert into the inner side of the connecting limit frame 24, thus quickly establishing a connection and positioning. Then, the end of the metal strip passes between the first guide roller 44 and the second guide roller 64, placing the metal strip in a W-shape. The end of the metal strip is then connected to the winding drum of the winding machine. During the winding process, the connecting cylinder 62 pushes and pulls the connecting end frame 63 and the second guide roller 64, allowing the second guide roller 64 to tension or relax the metal strip, thereby adjusting the tension of the metal strip. This facilitates the winding process of the metal strip by the winding machine. The overall structure is simple and the operation is convenient and quick.

[0057] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
