Description

Technical Field

[0001] This application relates to the field of stainless steel strip tensioning technology, and in particular to a stainless steel strip tensioning device. Background Technology

[0002] Stainless steel strip is a thin strip of metal material made of stainless steel, renowned for its excellent corrosion resistance, heat resistance, low-temperature strength, and superior mechanical properties. During the conveying process of stainless steel strip, ensuring sufficient friction between the strip and the rotating rollers is crucial. This prevents slippage and guarantees normal transport. Therefore, a certain tension is typically applied to the stainless steel strip.

[0003] Currently, tension rollers are typically installed in conveyor systems to adjust the tension of stainless steel strips. The stainless steel strip and the tension rollers work together through a rolling contact. The tension of the stainless steel strip can be adjusted by changing the overall lifting position of the tension rollers.

[0004] However, during the adjustment of the stainless steel strip tension, the stainless steel strip may sometimes slip relative to the tensioning roller along the axial direction of the tensioning roller. This relative slippage may cause the stainless steel strip to shift or misalign, affecting conveying efficiency and safety. Utility Model Content

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0029] This application discloses a stainless steel strip tensioning device.

[0030] A stainless steel strip tensioning device includes a frame 1, a tensioning roller 2, and a calibration component 3. The tensioning roller 2 is mounted on the frame 1 and is rotatably coupled with the frame 1. The calibration component 3 is mounted on the frame 1 near the tensioning roller 2. The tensioning roller 2 and the calibration component 3 work together to clamp the steel strip 4.

[0031] When the tensioning roller 2 adjusts the tension of the steel belt 4, the steel belt 4 on the tensioning roller 2 is calibrated by the calibration component 3 to reduce the possibility of the steel belt 4 shifting.

[0032] A waist groove 11 is provided on the side wall of the frame 1. The waist groove 11 is vertically arranged, and the end of the tension roller 2 passes through the waist groove 11. The tension roller 2 and the waist groove 11 slide together along the length of the waist groove 11, and the tension roller 2 and the waist groove 11 rotate together.

[0033] The frame 1 is provided with push units 12 at both ends. In this embodiment, the push unit 12 is a cylinder. The length direction of the cylinder is consistent with the length direction of the waist groove 11. One end of the cylinder is fixed on the frame 1. The end of the cylinder push rod is fixedly connected to a limit ring. The end of the tension roller 2 is placed in the limit ring, and the end of the tension roller 2 is rotatably engaged with the limit ring.

[0034] The calibration component 3 includes an adjusting rod 31 and a push ring 32.

[0035] The length direction of the adjusting rod 31 is consistent with the length direction of the tensioning roller 2. Both ends of the tensioning roller 2 and the adjusting rod 31 are provided with mounting seats 21. The tensioning roller 2 and the adjusting rod 31 are rotatably engaged with the mounting seats 21, and the mounting seats 21 on the tensioning roller 2 and the adjusting rod 31 are mounted on the frame 1. The mounting seats 21 and the frame 1 are slidably engaged along the length direction of the waist groove 11.

[0036] To facilitate the adjustment of the distance between the tension roller 2 and the adjusting rod 31, a spacing adjustment unit 34 is provided between the tension roller 2 and the adjusting rod 31. There are two sets of spacing adjustment units 34, which are located at both ends of the tension roller 2. The spacing adjustment unit 34 includes a mounting screw 341 and a mounting nut 342.

[0037] Each mounting base 21 is fixedly mounted with a mounting plate 22. A mounting screw 341 passes through the mounting plate 22, and a mounting nut 342 is threadedly connected to the mounting screw 341. By rotating the mounting nut 342, the mounting nut 342 and the screw head of the mounting screw 341 work together to clamp the mounting plates 22 on the two mounting bases 21, thereby limiting the maximum distance between two adjacent mounting bases 21.

[0038] The adjusting rod 31 is located below the tension roller 2, and under its own weight, the adjusting rod 31 is always at the maximum set distance from the tension roller 2. At the same time, when the tension roller 2 moves, the distance adjusting unit 34 makes the tension roller 2 and the adjusting rod 31 move synchronously.

[0039] There are two push rings 32, both of which are mounted on the adjusting rod 31. The axes of the two push rings 32 coincide with the axis of the adjusting rod 31, and the push rings 32 and the adjusting rod 31 are rotatably engaged. The tension roller 2 and the push rings 32 are both in rolling engagement with the steel belt 4.

[0040] A certain distance is left between the two push rings 32 to form a calibration area. In order to facilitate the adjustment of the size of the calibration area, the push ring 32 and the adjusting rod 31 slide together along the axis of the adjusting rod 31, and the push ring 32 is connected to the adjusting rod 31 through the locking unit 33.

[0041] The locking unit 33 includes a limit bar 331, a locking block 332, and a locking bolt 333.

[0042] The limiting strip 331 is fixedly installed on the outer circumferential surface of the adjusting rod 31, and the length direction of the adjusting rod 31 is consistent with the length direction of the limiting strip 331.

[0043] The inner wall of the push ring 32 is provided with a guide groove 322, and the limiting strip 331 is placed inside the limiting strip 331, and the limiting strip 331 slides in the guide groove 322. When the steel strip 4 is placed between the push ring 32 and the tension roller 2, during the rotation of the push ring 32, the thread on the push ring 32 applies a force to the steel strip 4 to move it towards the calibration area, thereby calibrating the steel strip 4. Its working principle is similar to that of a threaded rod.

[0044] The locking block 332 is fixedly installed at the end of the push ring 32. The locking block 332 is provided with a locking hole. The locking bolt 333 passes through the locking hole and is threadedly connected to the locking nut. The end of the locking bolt 333 abuts against the limit strip 331.

[0045] After adjusting the relative positions of the push ring 32 and the adjusting rod 31, tighten the locking bolt 333 so that the end of the locking bolt 333 abuts against the limiting strip 331, thereby improving the stability of the push ring 32.

[0046] A push groove 321 is spirally formed on the outer circumferential surface of the push ring 32 along the axial direction of the push ring 32, and the push grooves 321 of the two push rings 32 rotate in opposite directions.

[0047] The implementation principle of a stainless steel strip tensioning device in this application embodiment is as follows: When adjusting the tension of the steel strip 4, the tensioning tube is pushed to move inside the waist groove 11 by the pushing unit 12, thereby adjusting the tension of the steel strip 4. During the movement, the tensioning roller 2 drives the adjusting rod 31 to move synchronously through the spacing adjustment unit 34. When adjusting the spacing between the tensioning roller 2 and the adjusting rod 31, the maximum spacing between the tensioning roller 2 and the adjusting rod 31 is adjusted by the cooperation of the mounting screw 341 and the mounting nut 342. Under the action of its own gravity, the adjusting rod 31 is always at the maximum contact distance with the tensioning roller 2.

[0048] When adjusting the calibration area according to the width of the steel strip 4, the sliding push ring 32 is slidable and fastened to the guide bar by the locking bolt 333. The push ring 32 drives the adjusting rod 31 to rotate synchronously through the guide bar.

[0049] The steel belt 4 is located in the calibration area formed between the two push rings 32. When the steel belt 4 is deviated, the steel belt 4 is placed between the push ring 32 and the tension roller 2. During the rotation, the thread on the push ring 32 applies a force to the steel belt 4 to move towards the calibration area, thereby pushing the steel belt 4 back into the calibration area, thus calibrating the position of the steel belt 4.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
