Description

Technical Field

[0001] The present application relates to the technical field of metal processing center technology, and in particular to a material pulling device. Background Art

[0002] In the field of metal processing, in order to coat the steel strip, the steel strip must be tightened, cleaned, and other operations must be performed to ensure uniform and firm coating. A conventional pulling device is composed of two traction rollers and a matching driving device. Please refer to the utility model patent with publication number CN202369164U; the roll material conveying device includes: a feed roller and a continuous pulling roller; the feed roller and the continuous pulling roller are respectively connected to the intermittent feeding servo motor and the continuous pulling motor. Among them, the feed roller and its adjacent driven roller are arranged in parallel with a predetermined spacing, and the material belt passes between the feed roller and the driven roller and is clamped by the feed roller and the driven roller. When the driving device drives the feed roller to rotate, it will drive the driven roller to follow and realize the traction and pulling of the material belt. However, in actual applications, it is relatively difficult for the material belt to pass through the feed roller and the driven roller with a smaller spacing. In addition, the material belt has different thickness specifications, and the spacing between the feed roller and the driven roller is fixed, which makes it difficult to adapt to material belts of various specifications. If the material belt is too thick, it will cause the material belt to be unable to pass between the feed roller and the driven roller; if the material belt is too thin, it will cause the feed roller and the driven roller to have insufficient clamping force on the material belt and fail to provide good pulling force, which will cause the material belt to be unable to move forward normally, which is not conducive to production.

The driven roller 41 can be movably arranged on the mounting frame 20 and can move toward or away from the active roller 46, so as to adjust the distance between the active roller 46 and the driven roller 41, so that the two can clamp the material strips of different thicknesses. The active roller 46 can rotate under the drive of the driving device 10, and the driven roller 41 will rotate with the rotation of the active roller 46; the material strip passes between the driven roller 41 and the active roller 46 and is clamped by the driven roller 41 and the active roller 46. When the driving device drives the active roller 46 to rotate, the driven roller 41 follows and realizes the traction and pulling of the material strip, and the auxiliary roller 34 can guide, smooth and adjust the material strip to prevent the material strip from running off during movement. The overall structure of the present application is compact. By designing the mounting frame 20, the active roller 46 and the driven roller 41, the material strip is automatically pulled to achieve stretching and conveying of the material strip, thereby reducing the labor intensity of users and improving work efficiency. At the same time, the adjustment device facilitates the adjustment of the gap between the active roller 46 and the driven roller 41 to adapt to the pulling of material strips of different thicknesses.

[0050] In a possible implementation, the adjustment device includes: a handheld portion 45 and a screw rod 44; the handheld portion 45 is fixed to one end of the screw rod 44, and the other end of the screw rod 44 passes through the mounting frame 20 and is connected to the driven roller 41; the screw rod 44 and the mounting frame 20 are threadedly connected. Further, the handheld portion 45 is suitable for driving the screw rod 44 to rotate, and the top plate 22 of the mounting frame 20 is provided with a threaded hole, and the threaded hole matches the screw rod 44, and the screw rod 44 can rotate in the threaded hole and move up and down. One end of the screw rod is fixedly connected to the handheld portion 45, and the other end of the screw rod 44 passes through the threaded hole and is connected to the driven roller 41. Further, the handheld portion 45 is a circular handwheel structure. It should be noted that by rotating the hand wheel, the screw rod 44 can be raised and lowered relative to the top plate 22, thereby driving the driven roller 41 to rise and fall. When the driven roller 41 rises, it moves away from the active roller 46, and when the driven roller 41 drops, it approaches the active roller 46. The lifting degree of the driven roller 41 is adjusted according to the different thicknesses of the material strips, so that the driven roller 41 and the active roller 46 can firmly clamp the material strips of different thicknesses.

It should be noted that the setting of the sliding hole 21 is suitable for limiting the position of the connecting member 43. When the connecting member 43 moves driven by the screw rod 44, the connecting member 43 is always embedded in the sliding hole 21, which can ensure that the lifting of the connecting member 43 is kept in the vertical direction, so as to improve the lifting stability of the driven roller 41.

Here, it should be noted that the chain is sleeved on the outside of the first pulley 12 and the second pulley 14, and when the first pulley 12 rotates, the chain is driven to move, and the chain drives the second pulley 14 to rotate. Furthermore, the diameter of the second pulley 14 is larger than the diameter of the first pulley 12 to achieve rotation speed reduction.

[0056] In a possible implementation, the transmission mechanism includes: a hollow shaft clutch 15. The hollow shaft clutch 15 is connected to the central axis of the active roller 46.

[0063] When using the device, the gap between the active roller 46 and the driven roller 41 is increased by manually rotating the hand-held portion 45 to facilitate the passage of the material belt; Figure 4 As shown, the transmission direction of the material belt is that the material belt first passes through one of the auxiliary rollers 34, is wound around the outside of the driven roller 41, passes between the driven roller 41 and the active roller 46, and finally passes through the other auxiliary roller 34. According to the thickness of the material belt, the gap between the active roller 46 and the driven roller 41 is adjusted by rotating the hand-held part 45, so that the active roller 46 and the driven roller 41 tightly press the material belt; start the drive motor 11, and realize the frequency conversion control of the drive motor 11 through the inverter 18 to drive the movement of the active roller 46. The friction between the active roller 46 and the material belt, and the material belt and the driven roller 41 drives the movement of the material belt; at the same time, the hollow shaft clutch 15 is used to realize the control of the tension to ensure the constant traction tension; thereby achieving the purpose of balanced tension and constant force traction of the material belt.
