Description

Technical Field

[0001] The utility model relates to the technical field of tension adjusting devices, in particular to a tension adjusting device for steel strips. Background Art

[0002] Traditional steel strip tension adjustment devices can only accurately adjust the tension of steel strips of a specific size. Such devices usually rely on preset mechanical structures or adjustment mechanisms. These mechanisms are set during manufacturing to match a certain standard thickness of steel strip to ensure that the steel strip maintains a stable tension during transportation or processing.

[0003] When processing steel strips of varying thicknesses, these devices often fail to provide appropriate tension control, potentially leading to slack, slippage, or overstretching of the strips during transmission. This not only impacts production efficiency and product quality, but can also cause unnecessary wear and damage to the equipment itself.

[0004] In addition, traditional tension adjustment devices usually require tedious manual adjustment operations when replacing steel strips of different thicknesses, including disassembly and reinstallation of adjustment components, and may even require replacement of the entire adjustment system. This not only increases the complexity of operation, but also greatly reduces the flexibility and response speed of the production line. Utility Model Content

[0030] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installation," "splicing," and "connection" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] The following combination Figures 1 to 5 , describing a tension adjustment device for a steel belt according to an embodiment of the present utility model.

[0032] A tension adjustment device for a steel strip comprises a frame 1, a clamping assembly 2, a tension roller group 3 and an adjusting roller group 4; the clamping assembly 2 is mounted on the front side of the frame 1, the tension roller group 3 and the adjusting roller group 4 are both mounted on the rear side of the frame 1, the tension roller group 3 is fixedly mounted on the bottom of the frame 1, the adjusting roller group 4 is movably mounted on the top of the frame 1, the adjusting roller group 4 is vertically slidably connected to the frame 1, and a tension adjustment space for the steel strip is formed between the tension roller group 3 and the adjusting roller group 4.

[0033] The clamping assembly 2 is mounted on the front of the frame 1, firmly gripping the front end of the steel strip to prevent it from shifting or loosening as it enters the tension adjustment space. The tension roller assembly 3 is fixedly mounted on the bottom of the frame 1, providing a stable foundation for the entire device and ensuring that the tension roller assembly 3 does not wobble or shift during the operation of the steel strip, thus ensuring the stability of tension adjustment. The adjustment roller assembly 4 is movably mounted on the top of the frame 1 and is vertically slidably connected to the frame 1. The distance between the tension roller assembly 3 and the tension roller assembly 3 can be flexibly adjusted according to actual needs.

[0034] Through the mutual cooperation between the tension roller group 3 and the adjustment roller group 4, a specific tension adjustment space is formed in the vertical direction, so that the tension adjustment device of this scheme can adjust the tension of the steel strip more accurately, and can meet the strict requirements of different production processes for the tension of the steel strip, and solve the problem that the traditional steel strip tension adjustment device cannot effectively perform targeted tension adjustment according to the different thicknesses of the steel strip.

[0035] The adjusting roller group 4 includes an adjusting plate 41, a lifting assembly 42, a tension adjusting roller 43 and a connecting piece 44. Vertical slide grooves are provided at both ends of the frame 1. The adjusting plate 41 is slidably connected to the slide grooves. The left and right ends of the tension adjusting roller 43 are rotatably mounted on the adjusting plate 41. A lifting assembly 42 is provided on the top of the adjusting plate 41. The lifting assembly 42 is used to drive the adjusting plate 41 to move in the vertical direction. The connecting piece 44 horizontally connects the two lifting assemblies 42 at the left and right ends.

[0036] The adjustment plate 41 is slidably connected to a chute on the frame 1. The chute limits the range of motion of the adjustment plate 41, ensuring stability and linearity in its vertical movement. A lifting assembly 42 drives the adjustment plate 41 vertically to precisely adjust the strip tension, depending on the desired strip tension. By controlling the movement of the lifting assembly 42, subtle tension adjustments can be made, accurately varying the distance from the tension roller assembly 3 and achieving precise adjustment of the strip tension.

[0037] The connecting piece 44 horizontally connects the two lifting components 42 at the left and right ends, so that the two lifting components 42 can move synchronously, ensuring that the left and right ends of the tension adjustment roller 43 can be maintained at the same height, ensuring that the steel belt is evenly stressed during the tension adjustment process, and avoiding the deviation of the steel belt or local uneven tension.

[0038] The lifting assembly 42 includes a lifting cylinder 421, an adjusting gear 422 and an adjusting rack 423. The mounting end of the lifting cylinder 421 is fixedly connected to the top of the frame 1, and the movable end of the lifting cylinder 421 is fixedly connected to the top of the adjusting plate 41. The adjusting gear 422 is rotatably mounted on the adjusting plate 41, and the adjusting rack 423 is vertically mounted on the frame 1. The adjusting rack 423 is engaged with the adjusting gear 422, and the left and right ends of the connecting member 44 are fixedly connected to the two adjusting gears 422.

[0039] Simultaneously, the two lifting cylinders 421 are activated, driving the adjustment plate 41 up and down. The meshing of the adjustment gears 422 and the adjustment rack 423 causes the two adjustment gears 422 to rotate synchronously. The left and right ends of the connector 44 are connected to the adjustment gears 422, ensuring that the left and right ends of the tension adjustment roller 43 remain at the same height. This ensures that the force applied to the steel belt is even during tension adjustment, preventing deviation of the steel belt or uneven local tension.

[0040] The tension roller group 3 includes, from front to back, a first tension auxiliary roller 31, a tension active roller 32, a tension driving member 33, and a second tension auxiliary roller 34. The two ends of the first tension auxiliary roller 31 are rotatably mounted on the frame 1. The two ends of the tension active roller 32 are rotatably mounted on the frame 1. The movable end of the tension driving member 33 is fixedly connected to one end of the tension active roller 32 via a coupling 35. The two ends of the second tension auxiliary roller 34 are both rotatably mounted on the frame 1.

[0041] The adjusting roller group 4 is provided between the first tension auxiliary roller 31 and the tension active roller 32 , and the adjusting roller group 4 is also provided between the tension active roller 32 and the second tension auxiliary roller 34 ;

[0042] A clutch assembly 36 is provided on the outer side of the coupling 35 , and the clutch assembly 36 is used to control the rotation of the coupling 35 .

[0043] The tension roller group 3 comprises a first tension-assisting roller 31, a tension-driving roller 32, and a second tension-assisting roller 34, forming a complete tension transmission system. The tension-driving roller 32 is driven by a tension-driving element 33, effectively transmitting power to the steel strip and controlling its tension.

[0044] The first tension auxiliary roller 31 and the second tension auxiliary roller 34 assist in tension transmission, so that the steel strip can run more smoothly when passing through the tension roller group 3, reducing the vibration and fluctuation of the steel strip and improving the accuracy of tension adjustment.

[0045] The two adjusting roller groups 4 are respectively arranged between the first tension auxiliary roller 31 and the tension active roller 32 and between the tension active roller 32 and the second tension auxiliary roller 34, so as to flexibly adjust the height of the adjusting roller group 4 and further realize fine adjustment of the tension of the steel strip.

[0046] The movable end of the tension driving member 33 is fixedly connected to one end of the tension active roller 32 via a coupling 35, ensuring the reliability and stability of power transmission. The coupling 35 can effectively transmit torque, reduce power loss, and improve the working efficiency of the equipment.

[0047] The clutch assembly 36, located outside the coupling 35, provides greater flexibility in the operation and control of the equipment. By controlling the clutch assembly 36, the coupling 35 can be easily connected and disconnected, thereby controlling the rotation of the active tension roller 32. During equipment commissioning, maintenance, or emergency situations, the rotation of the active tension roller 32 can be quickly stopped, improving the safety and reliability of the equipment.

[0048] The clutch assembly 36 includes a clutch cylinder 361, a clutch rocker 362, a clutch screw 363 and a brake member 364. The mounting end of the clutch cylinder 361 is rotatably mounted on the frame 1. The driving end of the clutch cylinder 361 is hinged to the top of the clutch rocker 362. The bottom of the clutch rocker 362 is fixedly connected to the end of the clutch screw 363. The clutch screw 363 is rotatably mounted on the frame 1 and the bottom of the coupling 35. The clutch screw 363 is a bidirectional screw. The two brake members 364 are movably connected to the clutch screw 363. The two brake members 364 are respectively located on the front and rear sides of the coupling 35.

[0049] By rotating the clutch screw 363 , the two braking members 364 move closer to or farther away from each other.

[0050] The design of the clutch assembly 36 enables rapid clutching during operation. When the tensioning roller 32 needs to be stopped, the clutch cylinder 361 actuates rapidly, causing the clutch rocker 362 to swing, which in turn rotates the clutch screw 363. The two brake members 364 quickly close and grip the coupling 35, braking it. This rapid response allows the equipment to be stopped promptly in an emergency, improving safety.

[0051] At the same time, when the coupling 35 needs to be restored to rotation, the brake 364 can be quickly released from the coupling 35 by the reverse action of the clutch cylinder 361, thereby quickly starting the equipment. This flexible operation method greatly improves production efficiency and reduces equipment adjustment time.

[0052] Two brake members 364 are located on the front and rear sides of coupling 35. When brake members 364 are brought together, they symmetrically clamp coupling 35 from both sides, providing reliable braking force. This symmetrical braking method ensures that coupling 35 is evenly stressed during braking, preventing damage to coupling 35 or brake failure caused by excessive force on one side.

[0053] The clamping assembly 2 includes a clamping cylinder 21, a first clamping plate 22 and a second clamping plate 23. The second clamping plate 23 is horizontally installed on the frame 1, the first clamping plate 22 is located above the second clamping plate 23, and the end of the first clamping plate 22 is slidably connected to the frame 1 in the vertical direction. The mounting end of the clamping cylinder 21 is located on the frame 1, and the driving end of the clamping cylinder 21 is vertically connected to the top of the first clamping plate 22.

[0054] The ends of the first clamping plate 22 are vertically slidably connected to the frame 1, ensuring the linearity and stability of the clamping action. During the clamping process, the first clamping plate 22 can always remain parallel to the second clamping plate 23, applying the clamping force evenly to prevent localized deformation of the steel strip due to excessive force.

[0055] During the production process, when the steel strip needs to be replaced or the equipment needs to be adjusted, the clamping cylinder 21 can drive the first clamping plate 22 to rise and fall, so that the clamping assembly 2 can adapt to steel strips of different thicknesses, thereby improving the versatility of the equipment.

[0056] It is worth noting that when an abnormal situation of the steel strip is detected, the clamping cylinder 21 can immediately clamp the steel strip and stop the conveying of the steel strip in time to avoid accidents.

[0057] The adjustment plate 41 is provided with an inclined plate 45 below the tension adjustment roller 43 , and the inclined plate 45 is inclined upward from front to back.

[0058] The inclined plate 45, tilted upward from front to back, provides a natural guiding slope for the steel strip. As the steel strip enters the tension adjustment space from the clamping assembly 2, the inclined plate 45 allows the strip to smoothly transition to the tension adjustment roller 43, preventing the strip from jamming or bending due to sudden entry into the tension adjustment area.

[0059] During tension adjustment, the steel belt may sag due to its own weight or uneven tension. Inclined plate 45 effectively supports the steel belt and prevents it from sagging. The upward inclination angle of inclined plate 45 can be adjusted according to the weight and tension requirements of the steel belt, ensuring that the steel belt always remains in the proper position.

[0060] The centers of gravity of the first tension auxiliary roller 31 , the tension active roller 32 , and the second tension auxiliary roller 34 are all located on the same horizontal line.

[0061] When the centers of gravity of the first tension auxiliary roller 31, the tension active roller 32, and the second tension auxiliary roller 34 are on the same horizontal line, the steel strip can be subjected to more uniform tension when passing through the tension roller group 3, avoiding the difference in tension on the steel strip at different positions due to inconsistent centers of gravity of the tension roller group 3, thereby avoiding distortion and deformation, thereby improving product quality and appearance.

[0062] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
