Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, and in particular to a multi-level wire tension switching and adjustment device. Background Technology

[0002] In many industrial production processes, especially in the winding, traction, transmission or processing of wires, the control of wire tension is crucial. The accuracy and stability of wire tension directly affect the quality of products, production efficiency and the operating status of equipment. Excessive tension can cause the wire to stretch and deform, break, or even damage related equipment, while insufficient tension will cause the wire to slack and wind unevenly, affecting the forming accuracy and appearance quality of the final product.

[0003] Existing wire tension adjustment equipment typically employs various methods such as friction, magnetic resistance, or pneumatic to achieve tension control. While these methods can provide a certain level of tension adjustment capability in some applications, these traditional devices are often cumbersome to operate when switching tension levels. They require precise adjustment of multiple parameters or replacement of components to achieve different tension values. This not only reduces production efficiency but also leads to inconsistent tension settings between different batches or operators due to human error, affecting product consistency. Furthermore, on production lines that require rapid switching of tension levels to adapt to different process requirements, the switching speed and convenience of existing equipment are insufficient to meet actual needs, resulting in production interruptions or delays.

[0004] Therefore, this utility model proposes a multi-level line tension switching and adjustment device to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology, such as the inconvenience of operation and low precision of the multiple tension levels when switching wire tension in wire processing equipment, as well as the limited overall height adjustment of the equipment and its difficulty in adapting to diverse working environments, this utility model aims to provide a multi-level wire tension switching and adjustment device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a multi-level line tension switching and adjustment device, including: a fixed plate and a movable plate disposed on the top of the fixed plate, a switching mechanism is provided between the movable plates, and an adjustment mechanism is provided between the fixed plate and the movable plate.

[0007] The switching mechanism includes a rotating shaft, a cam, a turntable, rollers, a locking rod, and a locking slot. Multiple rollers are rotatably mounted on the inner wall of the cam. A turntable is fixedly connected to the left side of the rotating shaft. The cam is fixedly connected to the outer wall of the rotating shaft. A locking slot is opened on the outer wall of the cam. A locking rod is slidably connected to the inner wall of the moving plate. The locking rod passes through the moving plate and selectively engages with the locking slot.

[0008] Furthermore, the adjustment mechanism includes a telescopic block, a sliding frame, a T-shaped locking block, and a locking slot. The telescopic block is slidably connected to the inner wall of the fixed plate, and the top of the telescopic block is fixedly connected to the bottom of the moving plate. The sliding frame is fixedly connected to the outer wall of the telescopic block, and the inner wall of the sliding frame is slidably connected to a T-shaped locking block. The T-shaped locking block selectively engages and is fixed with multiple locking slots opened on the outer wall of the fixed plate.

[0009] Preferably, both ends of the rotating shaft are rotatably connected to the inner wall of the moving plate. This double-end supported structure enhances the stability of the rotating shaft's rotation.

[0010] Preferably, multiple rollers are distributed circumferentially along the cam, and the radial distance between each roller and the shaft is different, which ensures that different levels of tension are applied to the wire at different gear positions.

[0011] Preferably, the edge of the turntable has an anti-slip texture to provide good friction when the operator rotates it manually.

[0012] Preferably, the locking rod penetrates the moving plate, and the end of the locking rod is arc-shaped to facilitate smooth engagement and disengagement with the locking slot.

[0013] Preferably, a guide groove is provided between the inner wall of the sliding frame and the T-shaped block to ensure the directional accuracy and stability of the T-shaped block during the sliding process.

[0014] Preferably, multiple bayonets are evenly distributed along the height direction of the fixed plate, providing regular and easily identifiable height adjustment levels.

[0015] Preferably, the bottom of the fixing plate is provided with mounting holes for fixing the equipment, so that the equipment can be stably installed on the workbench or the ground.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of unclear tension adjustment gears, complicated switching operations, and unreliable tension locking in the prior art by setting a cam with multiple rollers at different radial positions and adjusting it with a turntable, and then using a locking rod to engage with the locking groove on the cam for positioning. It achieves the effect of clear gears, quick switching, and stable and reliable tension.

[0017] 2. This utility model solves the problem that existing equipment has a simple structure and fixed overall height, making it difficult to adapt to different working scenarios, by setting a sliding telescopic block between the fixed plate and the movable plate, and using a T-shaped card block to engage and fix it with multiple slots on the fixed plate. This achieves the effect of convenient overall height adjustment, wide applicability, and stable locking. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 5 This utility model provides a multi-level line tension switching and adjustment device, which aims to solve the problems of inconvenient operation and unclear levels when switching between multiple levels in existing line tension adjustment devices, as well as the difficulty in adapting the overall height of the device to different working scenarios.

[0022] Please refer to Figure 1 and Figure 2A multi-level tension switching and adjusting device includes a fixed plate 1 and a movable plate 4 disposed on top of the fixed plate 1. The bottom of the fixed plate 1 is provided with mounting holes for fixing the device. An adjusting mechanism 3 is provided between the fixed plate 1 and the movable plate 4. The adjusting mechanism 3 includes a telescopic block 301, a sliding frame 302, a T-shaped locking block 303, and a locking slot 304. The telescopic block 301 is slidably connected to the inner wall of the fixed plate 1, and the top of the telescopic block 301 is fixedly connected to the bottom of the movable plate 4. The movable plate 4 can be driven by sliding the telescopic block 301. Plate 4 moves up and down relative to fixed plate 1. Sliding frame 302 is fixedly connected to the outer wall of telescopic block 301. A T-shaped locking block 303 is slidably connected to the inner wall of sliding frame 302. A guide groove is provided between the inner wall of sliding frame 302 and the T-shaped locking block 303 to ensure the sliding direction of the T-shaped locking block 303. Multiple locking slots 304 are provided along the height direction of the outer wall of fixed plate 1, and these slots are evenly distributed along the height direction of fixed plate 1. The T-shaped locking block 303 can selectively engage with any of the multiple locking slots 304. The movable plates 4 are fixed together, thereby locking them at a specific height. A switching mechanism 2 is provided between the movable plates 4. The switching mechanism 2 includes a rotating shaft 201, a cam 202, a turntable 203, a roller 204, a locking rod 205, and a locking slot 206. The rotating shaft 201 is rotatably connected between the movable plates 4. Specifically, both ends of the rotating shaft 201 are rotatably connected to the inner wall of the movable plates 4. The turntable 203 is fixedly connected to one side of the rotating shaft 201. The edge of the turntable 203 is provided with anti-slip texture. The cam 202 is fixed to the outer wall of the rotating shaft 201 and moves with it. The rotating shaft 201 rotates synchronously, and multiple rollers 204 are rotatably mounted on the outer circumferential direction of the cam 202. The multiple rollers 204 are distributed along the circumference of the cam 202, and the radial distance between each roller 204 and the rotating shaft 201 is different. The outer wall of the cam 202 is provided with a slot 206, and a locking rod 205 is slidably connected to the inner wall of the moving plate 4. The locking rod 205 passes through the moving plate 4 and selectively engages with the slot 206. The end of the locking rod 205 is arc-shaped to facilitate engagement and disengagement with the slot 206.

[0023] Please refer to Figure 1 , Figure 2 , Figure 4The switching mechanism 2 includes a rotating shaft 201, a cam 202, a turntable 203, rollers 204, a locking rod 205, and a locking slot 206. Both ends of the rotating shaft 201 are rotatably connected to the inner wall of the moving plate 4. The turntable 203 is fixedly connected to one side of the rotating shaft 201. The edge of the turntable 203 has anti-slip textures to facilitate manual rotation by the operator. The cam 202 is fixedly connected to the outer wall of the rotating shaft 201 and rotates synchronously with the rotating shaft 201. The cam 202 is the core component for achieving multi-level switching of line tension. Multiple rollers 204 are rotatably mounted on the outer circumferential surface of the cam 202. The rollers 204 and the cam 202 are rotatably connected, allowing the line to contact the rollers 204. At 04, the wire can pass smoothly, reducing friction. Multiple rollers 204 are evenly distributed around the circumference of the cam 202. The radial distance between each roller 204 and the rotating shaft 201 is different, forming different tension application points. When the wire is placed on the inner wall of the roller 204, the wire is subjected to the top force of the roller 204 during transmission, thereby generating a certain tension. By rotating the turntable 203, the rotating shaft 201 can be driven to rotate, which in turn causes the cam 202 to rotate, adjusting the position of the rollers 204 at different heights to contact the wire. Due to the height difference of the rollers 204, the top force on the wire will change accordingly, thereby increasing or decreasing the wire tension and achieving the purpose of multi-level adjustment.

[0024] The outer wall of the cam 202 is provided with slots 206. The number and position of these slots 206 correspond to the effective tension levels of the roller 204. A locking rod 205 is slidably connected to the inner wall of the moving plate 4. The locking rod 205 passes through the moving plate 4 and can selectively engage with the slots 206. The end of the locking rod 205 is arc-shaped to facilitate engagement and disengagement with the slots 206. When it is necessary to adjust the line tension, the operator first needs to move the locking rod 205 on the inner wall of the moving plate 4 and slide it out from the inner wall of the slot 206 to release the restriction on the cam 202, allowing the cam 202 to rotate freely. After adjusting to the appropriate tension level, the locking rod 205 is slid back to the corresponding inner wall of the slot 206 for engagement and fixation. This prevents the cam 202 from rotating unexpectedly during transmission and ensures stable output of line tension. This engagement and locking structure ensures the reliability and stability after tension adjustment.

[0025] As a preferred embodiment, to improve the stability of the rotation of the shaft 201 and the reliability of the support, please refer to... Figure 1 and Figure 2 Both ends of the rotating shaft 201 are rotatably connected to the inner wall of the moving plate 4. For example, bearing seats can be set on the inner wall of the moving plate 4, and both ends of the rotating shaft 201 can be installed in the bearing seats. This double-end support structure can ensure that the rotating shaft 201 is subjected to uniform force when driving the cam 202 to rotate, avoiding shaking or eccentricity, thereby ensuring the accuracy of tension adjustment and the stability of long-term operation of the equipment.

[0026] As a preferred implementation, to achieve clear and differentiated multi-level tension adjustment, please refer to... Figure 4 Multiple rollers 204 are distributed circumferentially along the cam 202, and the radial distance between the axis of each roller 204 and the axis of the rotating shaft 201 is different. Through this eccentric design, when the cam 202 rotates, the rollers 204 with different radial distances will contact the line and generate different degrees of lifting on the line, thereby forming multiple fixed and repeatable tension levels.

[0027] As a preferred implementation method, to improve the convenience and reliability of manual operation, please refer to... Figure 1 The edge of the turntable 203 is provided with anti-slip texture, which can be knurled, grooved, or rubber-coated. This design increases the friction between the operator's hand and the turntable 203, making it easy to rotate even in oily or slippery environments, preventing slippage and ensuring accurate execution of adjustment actions.

[0028] As a preferred implementation, to make the gear locking and unlocking operation smoother, please refer to... Figure 1 and Figure 5 The locking lever 205 penetrates the movable plate 4, and the end of the locking lever 205 is arc-shaped. This arc-shaped head design can guide the locking lever 205 when it is inserted into or pulled out of the slot 206, reducing the resistance and alignment difficulty during insertion, making the locking and separation process smoother, and avoiding jamming caused by sharp corners.

[0029] As a preferred embodiment, to ensure the smooth movement and directional accuracy of the T-shaped card block 303 during locking and unlocking, please refer to... Figure 3 and Figure 5 A guide groove is provided between the inner wall of the sliding frame 302 and the T-shaped block 303. The T-shaped block 303 is provided with a guide rail that cooperates with the guide groove. The cooperation between the guide groove and the guide rail precisely limits the movement path of the T-shaped block 303, preventing tilting or rotation during sliding and ensuring that the T-shaped block 303 can be accurately aligned and slid into the slot 304 on the fixed plate 1.

[0030] As a preferred implementation, to provide a regular and easy-to-remember height adjustment range, please refer to... Figure 1 and Figure 2 Multiple bayonets 304 are evenly distributed along the height direction of the fixed plate 1. This evenly spaced setting ensures that the lifting height of the moving plate 4 is fixed for each adjustment level, providing the operator with a clear height reference and facilitating quick adjustment to the preset or commonly used working height.

[0031] As a preferred embodiment, to ensure that the equipment can be stably installed on the workbench or ground, please refer to... Figure 1 The bottom of the fixing plate 1 is provided with mounting holes for fixing the equipment. Through these mounting holes, bolts and fasteners can be used to firmly fix the entire equipment in the required working position to prevent the equipment from shifting due to vibration or external force during operation.

[0032] Working Principle: Before adjusting the line tension, first fix the two fixed plates 1 in the required working position. Through the mounting holes at the bottom of the fixed plates 1, bolts can be used to secure them. Since two movable plates 4 are set on the top of the two fixed plates 1, and an adjustment mechanism 3 is provided between the fixed plates 1 and the movable plates 4, when it is necessary to adjust the overall height of the equipment, the operator first slides the T-shaped locking block 303 on the inner wall of the sliding frame 302 out of the locking slot 304 on the outer wall of the fixed plate 1 to release the height lock. At this time, the movable plate 4 can slide up and down on the inner wall of the fixed plate 1 through the telescopic block 301, thereby realizing the adjustment of the overall height of the equipment. The telescopic block 301 is slidably connected to the inner wall of the fixed plate 1, and the top of the telescopic block 301 is fixedly connected to the bottom of the movable plate 4, ensuring that the movable plate 4... The device remains stable throughout the lifting process. The sliding frame 302 is fixedly connected to the outer wall of the telescopic block 301. The inner wall of the sliding frame 302 is slidably connected to a T-shaped locking block 303, and a guide groove is provided between the inner wall of the sliding frame 302 and the T-shaped locking block 303 to precisely guide the sliding direction of the T-shaped locking block 303. When the moving plate 4 is adjusted to a suitable height, the operator slides the T-shaped locking block 303 into the corresponding slot 304 on the outer wall of the fixed plate 1 for locking and fixing. Since the multiple slots 304 on the outer wall of the fixed plate 1 are evenly distributed along the height direction, they provide clear height adjustment levels. This locking and fixing method ensures that the height of the equipment is stable and reliable after adjustment, preventing the height from changing due to vibration during operation, thereby solving the problem of inconvenient equipment height adjustment in different working scenarios. After the equipment height is adjusted and fixed, the wire tension can be adjusted. A switching mechanism 2 is set between the two moving plates 4. The core component of the switching mechanism 2 is the cam 202. Multiple rollers 204 are rotatably mounted on the inner wall of the cam 202, and the rollers 204 are distributed around the circumference of the cam 202. The radial distance between each roller 204 and the rotating shaft 201 is different. This design is the key to realizing multi-level tension adjustment. The operator first places the wire whose tension needs to be adjusted on the inner wall of the roller 204, so that the wire is subjected to the pushing force of the roller 204 during transmission, thereby generating a certain initial tension in the wire. When it is necessary to switch the tension level, the locking rod 205, which is slidably connected to the inner wall of the moving plate 4, is moved on the inner wall of the moving plate 4 and slides out of the slot 206 on the outer wall of the cam 202, releasing the restriction on the cam 202. The end of the locking rod 205 is arc-shaped, making the unlocking process smooth. After the restriction is released, the operator rotates the fixed connection to the rotating shaft 201. A turntable 203 on one side has an anti-slip texture on its edge for easy operation. The turntable 203 drives the rotating shaft 201 to rotate, which in turn drives the cam 202 to rotate. As the cam 202 rotates, rollers 204 at different heights will contact the line. Due to the different radial distances between the rollers 204 and the rotating shaft 201, the force on the line will change accordingly, thereby increasing or decreasing the tension of the line and realizing multi-level adjustment of the line tension. Both ends of the rotating shaft 201 are rotatably connected to the inner wall of the moving plate 4 to ensure the stability and accuracy of the rotation process. After adjusting to the appropriate tension, the operator slides the locking rod 205 to the inner wall of the corresponding locking slot 206 to lock and fix the position of the cam 202, so that the cam 202 will not rotate during the transmission of the line, ensuring stable output of the line tension. Through the precise control of the switching mechanism 2, multi-level precise adjustment of the line is realized, solving the problem of insufficient line tension adjustment accuracy in the prior art.
