Description

Technical Field

[0001] This utility model relates to the field of painted steel strip technology, specifically to a main roller traction device for painted steel strip. Background Technology

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. It is generally supplied in coils and has advantages such as high dimensional accuracy, good surface quality, easy processing, and material saving.

[0003] In the prior art, it is not convenient to fix the end of the steel strip to the main roller before the main roller is pulled, which increases the labor intensity of the workers. Moreover, the tension of the steel strip cannot be guaranteed when the main roller is pulled, resulting in poor uniformity of the steel strip winding. Therefore, we have introduced a main roller pulling device for painted steel strip. Utility Model Content

[0004] The purpose of this utility model is to provide a main roller traction device for painted steel strip, which not only facilitates fixing the end of the steel strip to the main roller before traction, reducing the labor intensity of workers, but also ensures the tension of the steel strip during main roller traction, thereby improving the neatness of steel strip winding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A main roller traction device for painted steel strip includes a base, a support frame fixedly mounted on the upper end of the base, a main roller rotatably mounted on the upper end of the support frame via a rotating shaft, a motor fixedly mounted on the outer side of the support frame, the output end of the motor being fixedly connected to the rotating shaft, a strip groove provided on the circumferential wall of the main roller, a locking mechanism provided within the strip groove, a rectangular frame fixedly mounted on one side of the base, U-shaped frames hinged to the inner walls of both the upper and lower sides of the rectangular frame, tension rollers hinged to the other ends of the U-shaped frames, and a clamping mechanism provided between the U-shaped frames and the rectangular frame.

[0007] As a further embodiment of this utility model, the locking mechanism includes clamping plates and a bidirectional lead screw. The bidirectional lead screw is rotatably mounted in the strip groove via rolling bearings. Both ends of the bidirectional lead screw extend to the outside of the strip groove. The two clamping plates are symmetrically threaded on both sides of the bidirectional lead screw. The side of the two clamping plates closest to the rotating shaft is slidably connected to the groove wall of the strip groove.

[0008] As a further embodiment of this utility model, the clamping mechanism includes a guide block, which is fixedly mounted on the outer wall of the U-shaped frame. The inner side of the rectangular frame is provided with an arc-shaped groove that cooperates with the guide block. A tension spring is fixedly mounted on the side of the arc-shaped groove away from the tension roller, and the other end of the tension spring is fixedly connected to the guide block.

[0009] As a further embodiment of this invention, the tension spring is always in a stretched state.

[0010] As a further embodiment of this utility model, the side wall of the main roller is provided with a receiving groove corresponding to the position of the bidirectional lead screw, and both ends of the bidirectional lead screw extend into the receiving groove and are fixedly provided with a rotating wheel.

[0011] As a further embodiment of this invention, the circumferential wall of the wheel is provided with anti-slip texture.

[0012] As a further embodiment of this invention, a rubber sleeve is fixedly provided on the circumferential wall of the tension roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The main roller traction device for the painted steel strip, consisting of a base, support frame, main roller, rectangular frame, U-shaped frame, tension roller, motor, rotating shaft, rotating wheel, bidirectional screw, clamping plate, guide block, and tension spring, allows the end of the steel strip to pass through two tension rollers and be inserted into the strip groove. Inserting a finger into the receiving cavity and rotating the rotating wheel causes the bidirectional screw to rotate, which in turn causes the two clamping plates to clamp the end of the rotating steel strip. At this point, the motor is started, and its output drives the rotating shaft to rotate, which in turn drives the main roller to rotate. The steel strip winds around the roller wall of the main roller. The tension spring pulls the guide block, which in turn causes the two tension rollers to abut against each other via the U-shaped frame. The rubber sleeve increases the friction between the tension rollers and the steel strip, thereby increasing the tension of the main roller during steel strip traction. This not only facilitates fixing the end of the steel strip to the main roller before traction, reducing the labor intensity of workers, but also ensures the tension of the steel strip during main roller traction, thus improving the neatness of the steel strip winding.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution:

[0022] A main roller traction device for painted steel strip includes a base 1, a support frame 2 fixedly mounted on the upper end of the base 1, a main roller 3 rotatably mounted on the upper end of the support frame 2 via a rotating shaft 8, a motor 7 fixedly mounted on the outer side of the support frame 2, the output end of the motor 7 being fixedly connected to the rotating shaft 8, a strip groove provided on the circumferential wall of the main roller 3, a locking mechanism provided in the strip groove, a rectangular frame 4 fixedly mounted on one side of the base 1, U-shaped frames 5 hinged to the inner walls of the upper and lower sides of the rectangular frame 4, a tension roller 6 hinged to the other end of the U-shaped frame 5, a rubber sleeve fixedly mounted on the circumferential wall of the tension roller 6, the rubber sleeve increasing the friction between the tension roller 6 and the steel strip, thereby increasing the tension of the main roller when tractioning the steel strip, and a clamping mechanism provided between the U-shaped frame 5 and the rectangular frame 4.

[0023] The locking mechanism includes a clamping plate 11 and a double-acting screw 10. The double-acting screw 10 is rotatably mounted in the strip groove via rolling bearings. Both ends of the double-acting screw 10 extend to the outside of the strip groove. Two clamping plates 11 are symmetrically threaded on both sides of the double-acting screw 10. The side of the two clamping plates 11 closest to the rotating shaft 8 is slidably connected to the groove wall of the strip groove.

[0024] The clamping mechanism includes a guide block 12, which is fixedly mounted on the outer wall of the U-shaped frame 5. The inner side of the rectangular frame 4 is provided with an arc-shaped groove that cooperates with the guide block 12. A tension spring 13 is fixedly mounted on the side of the arc-shaped groove away from the tension roller 6. The tension spring 13 is always in a stretched state, and the other end of the tension spring 13 is fixedly connected to the guide block 12.

[0025] The side wall of the main roller 3 is provided with a receiving groove corresponding to the position of the bidirectional lead screw 10. Both ends of the bidirectional lead screw 10 extend into the receiving groove and are fixedly provided with a rotating wheel 9. The rotating wheel 9 makes it easy for the operator to rotate the bidirectional lead screw 10. The receiving groove provides a receiving space for the rotating wheel 9. The circumferential wall of the rotating wheel 9 is provided with anti-slip texture, which improves the friction of the circumferential wall of the rotating wheel 9.

[0026] In use, the end of the steel strip is passed through the two tension rollers 6 and inserted into the strip groove. A finger is inserted into the receiving cavity and the rotating wheel 9 is rotated. The rotating wheel 9 drives the bidirectional lead screw 10 to rotate. The bidirectional lead screw 10 drives the two clamping plates 11 to clamp the end of the rotating steel strip. At this time, the motor 7 is started. The output end of the motor 7 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the main roller 3 to rotate. The steel strip is wound on the roller wall of the main roller 3. Due to the tension spring 13 pulling the guide block 12, the two tension rollers 6 are driven to abut against each other through the U-shaped frame 5. The rubber sleeve increases the friction between the tension roller 6 and the steel strip, thereby increasing the tension of the main roller 3 when pulling the steel strip. This not only makes it easier to fix the end of the steel strip on the main roller 3 before traction, reducing the labor intensity of the workers, but also ensures the tension of the steel strip when the main roller 3 is pulling, thereby improving the neatness of the steel strip winding.
