Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, specifically to an adjustable tension structure for stainless steel strip coils. Background Technology
[0002] In stainless steel rolling production, whether hot or cold rolling, precise control of the strip tension is essential. For example, in cold rolling of stainless steel, the strip is thinned by rolling mills. If the tension is too low, the strip may slip between the rolls, leading to unstable rolling force and affecting the thickness accuracy and surface quality of the strip. Conversely, if the tension is too high, it may cause excessive stretching or even breakage of the strip.
[0003] Current technology typically relies on manual handling of counterweights to adjust tension. However, in practical applications, over time, the performance of ropes, chains, or other connecting components to the counterweights can change due to metal fatigue, wear, and other factors. For example, under the long-term stress of the counterweights and the tension of the winding belt, the elastic modulus of the rope gradually decreases, causing the originally set tension to gradually diminish. Furthermore, the counterweights themselves may change weight due to oxidation, corrosion, and other factors. All these factors make it difficult to maintain stable tension during long-term operation, requiring frequent inspections and recalibrations, increasing maintenance costs and production uncertainty.
[0004] Therefore, this application provides a stainless steel strip tension adjustable structure to meet the requirements. Utility Model Content
[0005] The purpose of this utility model is to provide a stainless steel strip tension adjustable structure, including:
[0006] A material support frame is provided with a feeding frame and a discharging frame on both sides, and the feeding frame and the discharging frame are installed on the material support frame by transmission rollers;
[0007] The transmission assembly includes a transmission shaft rotatably connected to the material receiving frame, the feeding frame, and the discharging frame. An arc-shaped block is rotatably connected to the transmission shaft, and a pressing element is slidably connected to the transmission shaft.
[0008] An electric telescopic rod is fixedly connected to the inside of the material receiving frame. A first transmission plate is fixed to the top of the electric telescopic rod, and a second transmission plate is fixedly connected to the bottom of the first transmission plate.
[0009] In a preferred embodiment, a motor is fixedly connected to the drive shaft, the motor is fixedly connected to the feed frame, a drive frame is slidably connected to the arc-shaped block, the drive frame has a sliding opening, a sliding shaft is fixedly connected to the pressing member, the sliding shaft is slidably connected to the sliding opening on the drive frame, a fixed frame is rotatably connected to the discharge frame, a fixed block is fixedly connected to the discharge frame, and a sliding frame is fixedly connected to the side of the arc-shaped block away from the drive shaft.
[0010] Using the above technical solution: In use, the sliding shaft on the pressing part is slid into the sliding port on the transmission frame by external force, which can fix the transmission frame. At this time, the motor is started, and the motor will drive the transmission shaft to continue to rotate, so that the arc block slides on the transmission frame, which will cause the sliding frame that wraps the transmission frame to expand outward, thereby increasing the diameter of the transmission shaft.
[0011] In a preferred embodiment, the top of the first transmission plate is fixedly connected to the material support frame, and the first transmission plate is rotatably connected to the transmission roller on the material support frame.
[0012] The above technical solution is adopted: When the electric telescopic rod lifts the transmission roller on the material receiving frame, it will drive the first transmission plate to rise, causing the arc plate to rotate on the rotating shaft. This causes the arc plate to drive the sliding block to move downward, causing the extrusion block to move downward. This avoids the loose part of the steel coil being lifted up when the stress of the steel coil is low and needs to be increased, which would cause wrinkles in the steel coil when it is rolled up.
[0013] In a preferred embodiment, an arc-shaped plate is fixedly connected to the second transmission plate, a sliding block is fixedly connected to the arc-shaped plate, and a pressing block is fixedly connected to the sliding block.
[0014] The above technical solution utilizes an arc-shaped plate to facilitate the transmission of the extrusion block.
[0015] In a preferred embodiment, a rotating shaft is rotatably connected to the arc-shaped block, and the rotating shaft on the arc-shaped block is rotatably connected to the transmission shaft.
[0016] The above technical solution is adopted: by setting a rotating shaft on the arc-shaped block, the arc-shaped block can be rotated to realize the transmission of the sliding frame.
[0017] In a preferred embodiment, a limiting rod is fixedly connected to the arc-shaped block, the limiting rod on the arc-shaped block is slidably connected to the transmission frame, and a rotating shaft is rotatably connected to the bottom of the discharge frame, the rotating shaft being rotatably connected to the arc-shaped plate.
[0018] The above technical solution is adopted: by setting a limit rod on the arc-shaped block, the arc-shaped block is prevented from sliding completely into the transmission frame when there is no need to adjust the stress of the steel coil.
[0019] In a preferred embodiment, the discharge frame is provided with a sliding hole, and the pressing member is slidably connected in the sliding hole on the discharge frame.
[0020] The above technical solution is adopted: by opening a sliding hole on the discharge frame, it is convenient for the pressing part to slide in it.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] 1. This utility model abandons traditional counterweights and their unstable connection methods, and adopts an innovative transmission method to adjust tension by having a motor drive the transmission shaft to rotate, causing the arc-shaped block to slide on the transmission frame. This mechanical transmission structure, based on a stable mechanical connection, effectively avoids the gradual decrease or unstable changes in tension caused by metal fatigue and wear of the counterweight connecting ropes, chains, and other components, as well as the oxidation and corrosion of the counterweight itself. For example, the motor controls the rotation angle and speed of the transmission shaft, thereby precisely adjusting the position of the arc-shaped block. This ensures that tension adjustment is no longer affected by external environmental factors affecting the counterweight system, guaranteeing that the tension of the stainless steel strip remains within a precise and stable range during long-term continuous production. This greatly improves the consistency of product quality and reduces the scrap rate caused by tension fluctuations.
[0023] 2. In this utility model, the electric telescopic rod and the transmission assembly work together to raise or lower the transmission roller on the material receiving frame, thereby changing the stress state of the belt. Combined with the motor's drive adjustment of the transmission shaft, the tension is stabilized at a suitable level in a timely manner when the belt speed changes, the thickness changes, or the processing technology is switched.

[0033] 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.
[0034] like Figures 1 to 5 As shown, the adjustable tension structure for stainless steel strip includes:
[0035] The material receiving frame 11 has a feeding frame 1 and a discharging frame 12 on its two sides, and the feeding frame 1 and the discharging frame 12 are mounted on the material receiving frame 11 by transmission rollers.
[0036] Transmission assembly 2 includes a transmission shaft 21 rotatably connected to the material receiving frame 11, the feeding frame 1, and the discharging frame 12. An arc-shaped block 23 is rotatably connected to the transmission shaft 21, and a pressing member 24 is slidably connected to the transmission shaft 21.
[0037] The electric telescopic rod 3 is fixedly connected to the inside of the material receiving frame 11. The top of the electric telescopic rod 3 is fixedly connected to the first transmission plate 31, and the bottom of the first transmission plate 31 is fixedly connected to the second transmission plate 32.
[0038] A motor 28 is fixedly connected to the drive shaft 21, and the motor 28 is fixedly connected to the feed frame 1. A drive frame 22 is slidably connected to the arc block 23, and a sliding opening is provided on the drive frame 22. A sliding shaft 25 is fixedly connected to the pressing member 24, and the sliding shaft 25 is slidably connected to the sliding opening on the drive frame 22. A fixed frame 27 is rotatably connected to the discharge frame 12, and a fixed block 26 is fixedly connected to the discharge frame 12. A sliding frame 29 is fixedly connected to the side of the arc block 23 away from the drive shaft 21. In use, the sliding shaft 25 on the pressing member 24 is slid into the sliding opening on the drive frame 22 by external force, which can fix the drive frame 22. At this time, the motor 28 is started, and the motor 28 will drive the drive shaft 21 to continue to rotate, so that the arc block 23 slides on the drive frame 22, which will cause the sliding frame 29 covering the drive frame 22 to expand outward, thereby increasing the diameter of the drive shaft 21.
[0039] This invention abandons traditional counterweights and their unstable connection methods, and adopts an innovative transmission method to adjust tension by having a motor 28 drive the transmission shaft 21 to rotate, causing the arc-shaped block 23 to slide on the transmission frame 22. This mechanical transmission structure, based on a stable mechanical connection, effectively avoids the gradual decrease or unstable changes in tension caused by metal fatigue and wear of the counterweight connecting ropes and chains, as well as oxidation and corrosion of the counterweight itself. For example, the motor 28 precisely controls the rotation angle and speed of the transmission shaft 21, thereby accurately adjusting the position of the arc-shaped block 23. This ensures that tension adjustment is no longer affected by external environmental factors affecting the counterweight system, guaranteeing that the tension of the stainless steel strip remains within a precise and stable range during long-term continuous production. This greatly improves product quality consistency and reduces the scrap rate caused by tension fluctuations.
[0040] Furthermore, such as Figures 1 to 5 As shown, the top of the first transmission plate 31 is fixedly connected to the material support frame 11, and the first transmission plate 31 is rotatably connected to the transmission roller on the material support frame 11. When the electric telescopic rod 3 lifts the transmission roller on the material support frame 11 during use, it will drive the first transmission plate 31 to rise, causing the arc plate 33 to rotate on the rotating shaft 34, causing the arc plate 33 to drive the sliding block 35 to move downward, causing the pressing block 36 to move downward, thus preventing the loose part of the steel coil from being lifted when the stress of the steel coil is low and needs to be increased, which would cause wrinkles in the steel coil when it is rolled up.
[0041] An arc-shaped plate 33 is fixedly connected to the second transmission plate 32, a sliding block 35 is fixedly connected to the arc-shaped plate 33, and an extrusion block 36 is fixedly connected to the sliding block 35. The arc-shaped plate 33 facilitates the transmission of the extrusion block 36.
[0042] A rotating shaft is rotatably connected to the arc-shaped block 23. The rotating shaft on the arc-shaped block 23 is rotatably connected to the transmission shaft 21. By setting a rotating shaft on the arc-shaped block 23, it is convenient for the arc-shaped block 23 to rotate, thereby realizing the transmission of the sliding frame 29.
[0043] A limiting rod is fixedly connected to the arc-shaped block 23. The limiting rod on the arc-shaped block 23 is slidably connected to the transmission frame 22. A rotating shaft 34 is rotatably connected to the bottom of the discharge frame 12. The rotating shaft 34 is rotatably connected to the arc-shaped plate 33. By setting a limiting rod on the arc-shaped block 23, the arc-shaped block 23 is prevented from completely sliding into the transmission frame 22 when there is no need to adjust the stress of the steel coil.
[0044] The above solution also has the problem that when the operator operates the pressing component 24, it will be stuck by the discharge frame 12, such as... Figures 1 to 4 As shown, a sliding hole is provided on the discharge frame 12, and the pressing member 24 is slidably connected in the sliding hole on the discharge frame 12. By providing a sliding hole on the discharge frame 12, it is convenient for the pressing member 24 to slide in it.
[0045] Working principle: such as Figures 1 to 5 As shown, firstly, the external force slides the sliding shaft 25 of the pressing member 24 into the sliding opening of the transmission frame 22 to fix the transmission frame 22. Then, the fixing frame 27 is slid into the fixing block 26 to prevent the pressing member 24 from rotating.
[0046] Next, the motor 28, which is fixedly connected to the drive shaft 21, is started, and the motor 28 drives the drive shaft 21 to rotate. Since the arc-shaped block 23 is rotatably connected to the drive shaft 21 through the rotating shaft, and the limiting rod on the arc-shaped block 23 is slidably connected to the drive frame 22, the arc-shaped block 23 will slide on the drive frame 22 when the drive shaft 21 rotates.
[0047] The sliding of the arc-shaped block 23 causes the sliding frame 29, which is fixedly connected to it, to expand outward, thereby increasing the diameter of the drive shaft 21. Because the change in the diameter of the drive shaft 21 during the belt drive process alters factors such as the wrap angle and friction of the belt on its surface, it increases the tension of the belt. For example, this operation can be used to increase the tension of stainless steel belts to meet the requirements of subsequent processing techniques, such as ensuring the stability of the belt during high-speed operation or precision machining.
[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
