[0024] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0025] According to the instruction manual Figure 1-5 As can be seen, the raw material for the spiral insert in the present invention is steel strip 7. Before operation, the horizontal position of the working box 5 is adjusted by the adjustment mechanism according to the required length of the spiral insert, so that the distance between the clamping mechanism 15 and the pressing mechanism 14 meets the required length. During operation, the steel strip 7 is rolled, which is not shown in the figure. Existing coil loading can be used. The conveying mechanism 12 conveys one end of the steel strip 7 into the position of the clamping mechanism 15 through the cutting mechanism 11 and the pressing mechanism 14. The clamping mechanism 15 clamps and fixes one end of the steel strip 7. The pressing mechanism 14 then presses the steel strip 7. The driving mechanism 17 drives the disc 16 and the clamping mechanism 15 on the disc 16 to rotate, thereby driving one end of the steel strip 7 to rotate and the other end to be fixed, thus forming a spiral product. Finally, the cutting mechanism 11 cuts it, the pressing mechanism 14 and the clamping mechanism 15 are opened, the processed product is unloaded, and the above steps are repeated. Compared with the existing technology, the present invention does not require pre-cutting, and the entire loading, clamping, and twisting process is continuous, which improves work efficiency. In addition, the working box 5 can be adjusted horizontally by an adjustment mechanism to change the distance between it and the clamping mechanism 14, thereby being suitable for processing steel strips 7 of different lengths, improving applicability.

[0026] Among them, the clamping mechanism 15 includes a fixed seat 30, an upper clamping block 25, a lower clamping block 26 and a threaded column 23. The fixed seat 30 is fixedly set on the side wall of the disc 16. A mounting groove 21 is opened on the fixed seat 30. The lower clamping block 26 is fixedly set at the bottom of the mounting groove 21. The upper clamping block 25 is vertically movably set at the upper part of the mounting groove 21. The threaded column 23 is screwed to the top of the fixed seat 30 and passes through the mounting groove 21. A fixing plate 24 is set at the bottom of the threaded column 23, and the fixing plate 24 is fixedly connected to the top of the upper clamping plate.

[0027] During operation, personnel can use an external wrench to twist the threaded column 23, thereby moving the fixing plate 24 and the upper clamping block 25. After inserting the steel strip 7, the threaded column 23 is tightened, so that the upper clamping block 25 and the lower clamping block 26 clamp the steel strip 7, which is a simple and convenient clamping method. In particular, a deep groove 22 is formed at the top of the fixing base 30 corresponding to the position of the threaded column 23. The upper end of the threaded column 23 is placed in the deep groove 22, hiding the threaded column 23 and reducing the space occupied.

[0028] Among them, the adjustment mechanism includes a second motor 1, a threaded rod 6 and a slider 4. A slide groove 19 is opened on the upper surface of the workbench 3 corresponding to the side away from the clamping assembly. The slider 4 is slidably connected to the slide groove 19. The working box 5 is set on the slider 4. The threaded rod 6 passes through the slider 4 and is screwed to the slider 4. One end of the threaded rod 6 passes through the workbench 3 and is connected to the output end of the second motor 1. The second motor 1 is fixedly connected to the outer wall of the workbench 3.

[0029] During operation, the output end of the second motor 1 rotates the threaded rod 6. Since the slider 4 is screwed to the threaded rod 6 and slidingly connected to the chute 19 on the workbench 3, the rotation of the threaded rod 6 drives the slider 4 horizontally, thereby adjusting the horizontal position of the work box 5. In other words, the position of the clamping mechanism 15 on the work box 5 is adjusted to accommodate the processing of steel strips 7 of different lengths. In particular, a limit plate 8 is provided within the chute 19 of the workbench 3. The end of the threaded rod 6, away from the second motor 1, is rotatably connected to the side wall of the limit plate 8, enhancing the stability of the entire adjustment mechanism.

[0030] Among them, the driving mechanism 17 includes a first motor 20, a pulley transmission group 27 and a central shaft 28. The first motor 20 is fixedly arranged on the side wall of the working box 5, and the central shaft 28 rotates through the side wall of the working box 5. One end of the central shaft 28 is fixedly connected to the side wall of the disc 16 and is coaxial, and the other end is connected to one end of the pulley transmission group 27. The other end of the pulley transmission group 27 is connected to the output end of the first motor 20.

[0031] During operation, the working output end of the first motor 20 rotates to drive the pulley transmission group 27 to transmit, thereby driving the central shaft 28 to rotate, and then driving the disc 16 and the clamping assembly on the disc 16 to rotate. The driving structure is simple and easy to repair and maintain.

[0032] Among them, the clamping mechanism 14 includes an upper pressing plate 13, a lower pressing plate 9 and a clamping lock 32. The lower pressing plate 9 is fixedly connected to the workbench 3, and one side of the bottom surface of the upper pressing plate 13 is rotatably connected to the lower pressing plate 9. The clamping lock 32 can clamp the upper pressing plate 13 and the lower pressing plate 9 together.

[0033] During operation, the upper pressing plate 13 rotates to press the steel belt 7, and the upper pressing plate 13 and the lower pressing plate 9 are pressed and fixed by the compression lock 32, which serves as a fixed end.

[0034] Among them, the conveying mechanism 12 includes a door-shaped plate 31, a pair of conveying rollers 29 and a crank 10. The door-shaped plate 31 is fixedly set on the workbench 3, a pair of conveying rollers 29 are set between the door-shaped plate 31, and the crank 10 is connected to one end of one of the conveying rollers 29. Turning the crank 10 can drive the conveying roller 29 to rotate.

[0035] During operation, a person rotates the crank 10 to drive the conveying roller 29 to rotate and convey the steel belt 7. The structure is simple and easy to repair and maintain.
