Description

Technical Field

[0001] This invention relates to the technical field of stainless steel strip processing equipment, specifically to a traction device for stainless steel strip processing. Background Technology

[0002] In the processing, production, and subsequent applications (such as stamping, slitting, coating, etc.) of stainless steel coils, winding and unwinding operations are frequently required, during which the coils are pulled and guided. Stainless steel coils possess high strength and a certain degree of toughness, but during traction, improper tension control or unstable path can easily lead to problems such as deviation, wrinkling, and surface scratches, severely affecting product quality and production efficiency. Existing coil traction and winding devices typically suffer from the following problems: 1. Many devices design the winding mechanism and the guiding traction mechanism as an inseparable whole. While this structure is robust, it greatly limits the applicability of the equipment. When it is necessary to change the winding station or to use the traction device with different winding equipment, the entire equipment is difficult to move and cannot flexibly adapt to changing production layouts and processes, resulting in low equipment utilization. This integrated design creates equipment redundancy, increases workshop floor space and investment costs; 2. Traditional guide rollers are usually fixed in position and cannot be finely adjusted according to the actual running conditions and process requirements of the belt. This makes it impossible to effectively control the wrap angle and tension of the belt in the travel path. Due to the inability to fine-tune, uneven tension distribution becomes the norm. Too little tension can easily cause the belt to loosen, deviate, and wrinkle, while too much tension may cause excessive stretching of the belt or create indentations on the surface. In particular, for stainless steel belts with different thicknesses, materials, or surface treatment requirements, a fixed guide system is difficult to achieve the optimal tension configuration. 3. Even if there are separable take-up seats and guide seats, their connection methods are often cumbersome. They may require tools to tighten multiple bolts, and disassembly and assembly are time-consuming and laborious. They cannot achieve quick docking and separation, which affects the convenience of production scheduling. In frequent workstation changes, cumbersome connection operations will directly lead to extended downtime and reduced overall production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a traction device for processing stainless steel strip coils, so as to solve the problems of poor equipment flexibility, inaccurate tension control and inconvenient connection mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a traction device for processing stainless steel strip, comprising a winding seat and a guide seat detachably and fixedly connected to the winding seat; The winding base includes a movable frame, a drive motor, and a steel coil frame. The movable frame is equipped with casters at the bottom. The drive motor is fixed on the movable frame. The output end of the drive motor is connected to the steel coil frame for driving the steel coil frame to rotate for winding or unwinding. The guide seat includes a fixed frame and at least one set of traction components. At least two first guide rollers for supporting stainless steel strip are rotatably arranged on the fixed frame. The traction components include a first mounting frame and a second guide roller rotatably arranged on the first mounting frame. The fixed frame is provided with a connecting component for connecting with the movable frame.

[0005] Preferably, both ends of the steel coil frame are fixedly connected to one end of two rotating shafts, and the other end of the rotating shafts is rotatably connected to a support frame fixed to the top of the movable frame through a first bearing. The rotating shaft at one end of the steel coil frame is connected to the output end of the drive motor to ensure the stability and load-bearing capacity of the steel coil frame when rotating at high speed.

[0006] Preferably, the movable frame is provided with a connecting block.

[0007] Preferably, the connecting assembly includes a first connecting seat and a second connecting seat. The first connecting seat has an insertion hole adapted to the connecting block. The second connecting seat is fixedly connected to one side of the first connecting seat. The second connecting seat is threadedly connected to a first vertical screw and slidably connected to a vertical rod. The bottom end of the first vertical screw is rotatably connected to the top of the fixing frame through a second bearing. The bottom end of the vertical rod is fixed to the top of the fixing frame. The top end of the first vertical screw is fixedly connected to a first crank handle, which enables precise positional adjustment of the connecting assembly in the vertical direction, thereby compensating for possible installation height errors between the take-up seat and the guide seat, and ensuring that the connecting block can be smoothly inserted into the insertion hole.

[0008] Preferably, the first connecting seat is provided with a locking mechanism, which includes a first guide cylinder. The first guide cylinder is fixed on the first connecting seat, and its axis communicates with the insertion hole. A locking screw is threaded into the first guide cylinder. A knob is fixedly connected to one end of the locking screw. The other end of the locking screw is driven by the knob to be screwed into the insertion hole and pressed against the connecting block. This locking mechanism provides a quick connection and fixing method without additional tools, which greatly improves the efficiency of disassembly and assembly.

[0009] Preferably, the first mounting frame includes a fixed frame, a movable frame, and a lifting and adjusting mechanism. The fixed frame includes a first horizontal plate and two first vertical plates. The first horizontal plate is fixedly connected between the top ends of the two first vertical plates. The movable frame is slidably connected in the fixed frame. The movable frame includes a second horizontal plate and two second vertical plates. The second horizontal plate is fixedly connected between the top ends of the two second vertical plates. The lifting and adjusting mechanism is connected between the fixed frame and the movable frame. The second guide roller is rotatably connected between the two second vertical plates.

[0010] Preferably, the inner side of the first vertical plate is provided with a sliding groove, the bottom end of which extends to the fixed frame. The two sides of the second vertical plate are provided with extension blocks, which are embedded in the sliding groove and can slide along the sliding groove. The cooperation between the sliding groove and the extension blocks provides a stable and wobbly vertical guide for the movable frame, ensuring that the second guide roller remains horizontal during the lifting process.

[0011] Preferably, the lifting and adjusting mechanism includes a second guide cylinder, which is fixed to the middle of the first horizontal plate. A second vertical screw is threaded into the second guide cylinder. The bottom end of the second vertical screw is rotatably connected to the top of the second horizontal plate through a third bearing. A second crank is fixedly connected to the top end of the second vertical screw. The lifting and lowering of the second guide roller can be precisely controlled by manually rotating the second crank. The structure is simple and reliable, and the adjustment accuracy is high.

[0012] Preferably, a gap is formed between the second guide roller and the second cross plate for the stainless steel strip to pass through. This gap effectively constrains the strip and suppresses it from deviating during operation.

[0013] Preferably, there are two sets of traction components arranged side by side on the fixed frame. The configuration of the dual traction components allows the stainless steel strip to travel in an "S" shaped path. By increasing the wrap angle, the friction and control force on the stainless steel strip are enhanced, thereby achieving the tension control effect.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The winding seat and the guide seat are detachably connected by a connecting component, allowing the winding seat to move independently and be flexibly used with different winding seats, which improves equipment utilization and the convenience of production scheduling. 2. Adjust the traction components according to requirements using the lifting and adjusting mechanism to control the height of the second guide roller in each traction component, thereby adjusting the stainless steel strip travel path and tension to reduce the risk of strip deviation and wrinkling due to improper tension and improve processing quality. 3. The connecting components adopt a combination of plug-in mating and screw fine adjustment, supplemented by a manual knob locking mechanism, to achieve quick and stable docking and separation between the winding seat and the guide seat. This process does not require external tools, is simple to operate, and saves time and effort. 4. The constraint gap formed between the second guide roller and the second horizontal plate, combined with the liftable design, provides an adjustable and stable passage for the belt winding, fundamentally improving the trajectory stability of the belt winding.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] Example: Please refer to Figures 1-6 The present invention provides a technical solution: a traction device for processing stainless steel strip, including a winding seat and a guide seat that is detachably and fixedly connected to the winding seat; The winding stand includes a movable frame 1, a drive motor 2, and a steel coil frame 3. The drive motor 2 is a DMKE28-TEC2838 and is electrically connected to an external power source via a power cord. The steel coil frame 3 is used to wind up stainless steel strip. The bottom of the movable frame 1 is equipped with casters with brakes, enabling the movable frame 1 to move and position itself. The drive motor 2 is fixed to the movable frame 1, and the output end of the drive motor 2 is connected to the steel coil frame 3 via a coupling to drive the steel coil frame 3 to rotate for winding or unwinding. The guide seat includes a fixed frame 4 and at least one set of traction components. At least two first guide rollers 41 are rotatably mounted on the fixed frame 4 for supporting the stainless steel strip. The traction components include a first mounting frame 5 and a second guide roller 51 rotatably mounted on the first mounting frame 5. The fixed frame 4 is provided with a connecting component 6 for connecting with the movable frame 1.

[0019] In this embodiment, the two ends of the steel coil frame 3 are respectively fixedly connected to one end of two rotating shafts, and the other end of the rotating shafts is rotatably connected to the support frame 31 fixed to the top of the movable frame 1 through the first bearing. The rotating shaft at one end of the steel coil frame 3 is connected to the output end of the drive motor 2.

[0020] In this embodiment, the mobile frame 1 is provided with a connecting block 11.

[0021] In this embodiment, the connecting assembly 6 includes a first connecting seat 61 and a second connecting seat 62. The first connecting seat 61 has an insertion hole 65 that matches the connecting block 11. The second connecting seat 62 is fixedly connected to one side of the first connecting seat 61. The second connecting seat 62 is threadedly connected to the first vertical screw 63 and slidably connected to the vertical rod 64. The bottom end of the first vertical screw 63 is rotatably connected to the top of the fixing frame 4 through a second bearing. The bottom end of the vertical rod 64 is fixed to the top of the fixing frame 4. The top end of the first vertical screw 63 is fixedly connected to a first crank handle. Rotating the first crank handle causes the first vertical screw 63 to rotate. Since the first vertical screw 63 is threadedly connected to the second connecting seat 62, and the second connecting seat 62 is connected to the vertical rod 64... The restriction prevents rotation, thus causing the entire connecting assembly 6 to adjust its height, allowing the connecting block 11 on the movable frame 1 to be inserted into the insertion hole 65 on the fixed frame 4. By finely adjusting the precise position of the connecting assembly in the vertical direction, any possible installation height error between the take-up seat and the guide seat is compensated, ensuring that the connecting block can be smoothly inserted into the insertion hole.

[0022] In this embodiment, a locking mechanism is provided on the first connecting seat 61. The locking mechanism includes a first guide cylinder 66, which is fixed on the first connecting seat 61. Its axis communicates with the insertion hole 65. A locking screw 67 is threaded into the first guide cylinder 66. A knob 68 is fixedly connected to one end of the locking screw 67. The other end of the locking screw 67 is driven by the knob 68 to be screwed into the insertion hole 65 and pressed against the connecting block 11. The knob 68 can be rotated clockwise to lock, and rotated counterclockwise to quickly separate. The operation is extremely simple. This locking mechanism provides a fast connection and fixation method without additional tools, which improves the efficiency of disassembly and assembly.

[0023] In this embodiment, the first mounting frame 5 includes a fixed frame, a movable frame, and a lifting adjustment mechanism. The fixed frame includes a first horizontal plate 52 and two first vertical plates 53. The first horizontal plate 52 is fixedly connected between the top ends of the two first vertical plates 53. The movable frame is slidably connected in the fixed frame. The movable frame includes a second horizontal plate 56 and two second vertical plates 57. The second horizontal plate 56 is fixedly connected between the top ends of the two second vertical plates 57. The lifting adjustment mechanism is connected between the fixed frame and the movable frame. The second guide roller 51 is rotatably connected between the two second vertical plates 57.

[0024] In this embodiment, the inner side of the first vertical plate 53 is provided with a sliding groove 58, the bottom end of the sliding groove 58 extends to the fixed frame 4, and the two sides of the second vertical plate 57 are provided with extension blocks 59. The extension blocks 59 are embedded in the sliding groove 58 and can slide along the sliding groove 58, so that the movable frame can slide up and down stably.

[0025] In this embodiment, the lifting adjustment mechanism includes a second guide cylinder 54, which is fixed to the middle of the first horizontal plate 52. A second vertical screw 55 is threadedly connected to the second guide cylinder 54. The bottom end of the second vertical screw 55 is rotatably connected to the top of the second horizontal plate 56 through a third bearing. A second crank is fixedly connected to the top end of the second vertical screw 55. Rotating the second crank drives the second vertical screw 55 to rotate, thereby driving the entire movable frame and the second guide roller 51 to rise and fall smoothly, so that the stainless steel strip can be adjusted in height when passing through the gap between the second guide roller 51 and the second horizontal plate 56.

[0026] In this embodiment, a gap is formed between the second guide roller 51 and the second horizontal plate 56 for the stainless steel strip to pass through. The size of the gap is slightly larger than the thickness and width of the strip, which can effectively pull and constrain the strip without causing excessive friction.

[0027] In this embodiment, there are two sets of traction components, which are arranged side by side on the fixed frame 4 to traction different sections of the conveyor belt.

[0028] During operation, first move the take-up unit to the guide seat, and rotate the first crank to finely adjust the height of the connecting component 6, so that the connecting block 11 on the steel coil frame 3 is inserted into the insertion hole 65 on the fixed frame 4. After insertion, rotate the knob 68 at one end of the locking screw 67 clockwise to drive the other end of the locking screw 67 into the insertion hole 65 and press against the connecting block 11, thus fixing the take-up unit and the guide seat. Then, perform the threading operation, passing one end of the stainless steel coil over the top of the first guide roller 41 on the fixed frame, and then introducing it into the first traction component, passing it around the bottom of the second guide roller 51, or, depending on the tension requirements, passing it through the gap between the second guide roller 51 and the second cross plate 56. After that, guide it to the second traction component, using the same or different threading method as the previous component (for example, one passes around from the bottom, and the other passes through the gap, forming an "S" shaped path), and fix it to the central axis of the steel coil frame 3. After the tape is threaded, depending on the material, thickness, and required process tension of the current roll, rotate the second crank on each of the two traction components to adjust the height of the two second guide rollers 51 and observe the tension of the roll until the optimal state is reached. This adjustment process can be carried out when the equipment is stationary or running at low speed. Finally, start the drive motor 2 to drive the steel roll frame 3 to rotate in the required direction, so as to perform stable and efficient winding or unwinding operations on the stainless steel roll. Throughout the process, the tension can be finely adjusted at any time through the lifting adjustment mechanism to deal with any potential deviation or wrinkling trend.
