Description

Technical Field

[0001] This utility model relates to the field of tension roller technology, and in particular to an adjustable tension compensation tension roller assembly. Background Technology

[0002] Tensioner rollers play a crucial role in silicon steel production lines. Their core function is to ensure the stable operation of the steel strip by dynamically adjusting the tension. By adjusting the tension between the rollers, the steel strip is prevented from becoming slack or overstretched during production, thus ensuring the flatness and thickness consistency of the steel strip. Reasonable tension can reduce steel strip breakage or damage, and improve the stability and efficiency of the production line. The precise adjustment of tensioner rollers plays a vital role in the stability, efficiency, and final product quality of silicon steel production lines.

[0003] However, traditional tensioning roller sets cannot achieve uniform bidirectional tension, resulting in uneven tension of the steel strip in the vertical direction. This affects product quality and production efficiency. The lack of a flexible adjustment mechanism makes it impossible to precisely adapt to the tension requirements under different working conditions, leading to insufficient precision in adjustments and difficulty in coping with complex production environments. This results in fluctuations in steel strip tension or inaccurate positioning, thus affecting the stability of the entire production process. Therefore, this invention proposes an adjustable tension-compensating tensioning roller set to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable tension compensation tension roller assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable tension-compensating tensioning roller assembly includes a roller assembly frame. Two adjusting frames are rotatably connected to both the left and right sides of the roller assembly frame, with the two adjusting frames on the same side being cross-connected. Two tensioning rollers are arranged on the upper side inside the roller assembly frame, and two tensioning rollers are arranged on the lower side inside the roller assembly frame. The tensioning rollers are rotatably connected to the upper end between the corresponding two adjusting frames, and the tensioning rollers are arranged at the lower end between the corresponding two adjusting frames. Slider blocks are rotatably connected to both the left and right ends of the tensioning rollers. The lower part of the adjusting frame has a groove corresponding to the slider. Restriction grooves corresponding to the ends of the two tensioning rollers are opened on both the left and right sides of the roller assembly frame.

[0007] Preferably, two gears are rotatably connected inside the left and right sides of the roller frame, and a sliding C-shaped toothed plate is provided on the upper side of the roller frame.

[0008] Preferably, both sides of the incline toothed plate are located between the two gears, and both sides of the incline toothed plate are provided with tooth grooves that mesh with the gears.

[0009] Preferably, a screw is rotatably connected to the upper middle side of the roller frame, the screw is threadedly connected to the C-shaped toothed plate, and a throttle is fixed to the upper end of the screw.

[0010] Preferably, a gear three is fixed to the outer side of the adjustment frame junction, and a gear two is fixed to the outer end of each of the two gears one on the same side, and the two gears two mesh with the corresponding two gears three.

[0011] Preferably, a positioning stud is fixed on the upper side of the slider, a slot corresponding to the positioning stud is opened on the lower part of the adjustment frame, and a positioning nut that is in close contact with the surface of the adjustment frame is provided on the positioning stud.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The tension compensation tension roller group of this utility model uses two sets of tension rollers (tension roller one and tension roller two) to act on the steel strip in the vertical direction to achieve uniform bidirectional tension, thereby ensuring the stability and uniformity of the steel strip tension and adapting to different production needs. The design of the cross adjustment frame provides a flexible adjustment range, which can accurately adjust the tension force according to different working conditions.

[0014] 2. The gear transmission system of this utility model adjusts the position of the tensioning roller precisely by adjusting the screw rotation synchronously with the adjustment frame, thereby improving the adjustment accuracy and response speed.

It is particularly suitable for production environments that require high-precision tensioning.

[0015] 3.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 An adjustable tension compensation tensioning roller assembly includes a roller frame 1. Two adjusting frames 2 are rotatably connected to both the left and right sides of the roller frame 1. The two adjusting frames 2 on the same side are cross-connected. Two tensioning rollers 3 are arranged on the upper side inside the roller frame 1, and two tensioning rollers 4 are arranged on the lower side inside the roller frame 1. The tensioning rollers 3 are connected to the upper end between the corresponding two adjusting frames 2, and the tensioning rollers 4 are arranged at the lower end between the corresponding two adjusting frames 2. The upper set of two tensioning rollers 3 and the lower set of two tensioning rollers 4 can work together to achieve the tensioning effect on the passing silicon steel. Moreover, with the cross-connected adjusting frame 2 structure, when the upper two adjusting frames 2 rotate straight, the tensioning of the passing silicon steel can be achieved.

[0023] The roller frame 1 is the supporting frame of the entire tensioning system. Two adjusting frames 2 are connected to its left and right sides respectively. These adjusting frames 2 are connected by a cross-connection. This cross-structure design can improve the flexibility and adjustment range of the tensioning roller group, especially when the tensioning roller group needs to be precisely adjusted according to different working conditions. Tensioning roller 1 3 and tensioning roller 2 4 are located on the upper and lower sides of the roller frame 1 respectively. By setting two sets of tensioning rollers, the bidirectional tensioning effect on the steel strip can be ensured, thereby improving the uniformity and stability of the tension. This design can realize the stable transmission and tension control of the steel strip during the production process. Tensioning roller 1 3 is connected to the upper end of the adjusting frame 2, and tensioning roller 2 4 is connected to the lower end of the adjusting frame 2. The tensioning rollers distributed vertically can act on both directions of the steel strip at the same time, ensuring that the steel strip maintains appropriate tension in each stage. The cross-connection design of the adjusting frame 2 is flexible and can adjust the relative position of the two sets of tensioning rollers according to production needs. The working state of the tensioning rollers can be changed by rotating the adjusting frame 2, thereby precisely adjusting the tension of the steel strip.

[0024] Two gears 7 are rotatably connected to the inside of both sides of the roller frame 1. A sliding C-shaped toothed plate 6 is provided on the upper side of the roller frame 1. Both sides of the C-shaped toothed plate 6 are located between the two gears 7. The C-shaped toothed plate 6 has tooth grooves on both sides that mesh with the gears 7. A screw 5 is rotatably connected to the upper middle side of the roller frame 1. The screw 5 is threadedly connected to the C-shaped toothed plate 6, and a handle is fixed to the upper end of the screw 5. A gear 9 is fixed to the outer side of the adjustment frame 2. Gears 8 are fixed to the outer ends of the two gears 7 on the same side. The two gears 8 mesh with the corresponding two gears 9. By rotating the central screw 5, the C-shaped toothed plate 6 in the middle moves up and down. The C-shaped toothed plate 6 drives the meshing gears 7 on both sides, so that the gears 7 on both sides rotate towards each other. The gears 7 drive the gears 8 fixed on the outer side to rotate. The gears 8 drive the adjustment frame 2 connected to the gears 9 to rotate, so that the adjustment frame 2 on both sides rotates towards each other, thereby achieving tensioning of the silicon steel plate.

[0025] The coordination of gear 7, gear 8, and gear 9 makes the adjustment of the tension roller group more stable and efficient. The design of the zig-shaped toothed plate 6 sliding up and down can be controlled by rotating the central screw 5, thereby driving the rotation of gear 7 on both sides. The rotation of gear 7 will further drive the rotation of gear 8, and finally adjust the rotation of the adjustment frame 2 through gear 9. The key point of this gear transmission system is that the rotation of one screw 5 can synchronously adjust the two adjustment frames 2, so that the tension on both sides of the steel strip is always consistent. This design greatly improves the accuracy and response speed of the system, and can quickly respond to different tension requirements in production. By rotating the screw 5, the zig-shaped toothed plate 6 moves up and down, and then changes the position of the adjustment frame 2 through gear transmission. This drive method can achieve fine tension adjustment and improve the compensation and adjustment capability of tension under different production conditions.

[0026] Both ends of the tension roller 2 4 are rotatably connected to sliders 11. The lower part of the adjusting frame 2 is provided with a groove 10 corresponding to the slider 11. Both sides of the roller frame 1 are provided with limiting grooves 14 corresponding to the ends of the two tension rollers 3. The upper side of the slider 11 is fixed with a positioning stud 12. The lower part of the adjusting frame 2 is provided with a groove corresponding to the positioning stud 12. The positioning stud 12 is provided with a positioning nut 13 that is close to the surface of the adjusting frame 2. In order to adapt to different tensioning conditions, the upper and lower positions of the tension roller 2 4 at the lower part of the adjusting frame 2 can also be adjusted to achieve more precise tensioning adjustment. The tension roller 2 4 slides up and down between the two adjusting frames 2 through the sliders 11 at both ends. By rotating the positioning nut 13 on the positioning stud 12, the upper and lower positions of the slider 11 in the groove 10 are fixed, thereby determining the upper and lower positions of the tension roller 2 4 on the adjusting frame 2.

[0027] Each tensioning roller 2 4 is equipped with sliders 11 at both ends. These sliders 11 can slide up and down in the grooves 10 of the adjusting frame 2. This allows the vertical position of the tensioning roller 2 4 to be changed by adjusting the position of the sliders 11 under different tensioning conditions, ensuring precise control of the steel strip tensioning effect. The design of the positioning stud 12, in conjunction with the positioning nut 13, allows the position of the tensioning roller 2 4 to be fixed by tightening the nut after adjustment, thereby ensuring that the relative position of the adjusting frame 2 and the tensioning roller 2 4 will not shift. This design effectively improves the stability and durability of the tensioning system during long-term operation. Through the cooperation of the positioning nut 13 and the slider 11, very fine adjustments can be made to adapt to different production needs. This design is particularly suitable for production processes that require very precise tension control, such as the high tension requirements in silicon steel production lines.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
