Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and more specifically to a vertical winding machine for preventing steel strip rolls from tipping over. Background Technology

[0002] The vertical steel strip winding machine is an industrial equipment specifically designed for steel strip winding. It adopts a vertical layout and rotates the steel strip to neatly coil it into a roll, ensuring the tightness and stability of the steel strip roll. It achieves efficient material collection or slitting operations, facilitating subsequent processing, storage and transportation, and is widely used in metal processing, steel production and other fields.

[0003] Vertical strip winding machines are generally equipped with conveyor rollers. The steel strip coil is placed vertically on the conveyor rollers, and the rotating conveyor rollers are used to wind the steel strip. However, current vertical strip winding machines lack anti-tipping functions, resulting in significant reliability defects during operation. Specifically, the vertically positioned steel strip coil, supported only by the conveyor rollers, is prone to tipping over, especially during the conveyor roller process, where the center of gravity is easily shifted, causing frequent instances of the entire steel strip coil tipping over. To address these defects, existing solutions generally rely on manual intervention. During the winding operation, operators manually support the steel strip coil for axial positioning throughout the entire process. Due to the large weight of the steel strip coil, manual support is not only extremely labor-intensive but also carries a significant safety risk of injury from the coil tipping over. Furthermore, relying on real-time visual observation of the steel strip coil's position is limited by the viewing angle and human judgment errors, making it difficult to achieve precise axial alignment. Ultimately, this leads to quality defects in the finished winding product, such as interlayer misalignment and uneven edges, seriously affecting subsequent processing, storage, and transportation. Utility Model Content

[0004] In response to the above situation, and to overcome the problems of existing vertical steel strip winding machines lacking anti-tipping functions, which cause the steel strip to easily shift its center of gravity during winding operations, requiring manual support for axial positioning, this invention aims to provide a vertical winding machine that can apply symmetrical clamping force to the steel strip coil, effectively positioning it axially without requiring manual support, thus significantly improving production safety, and also enhancing the tightness and end-face uniformity of the steel strip coil.

[0005] To achieve the above objectives, the technical solution of this utility model is: A vertical winding machine for preventing steel strip rolls from tipping over includes a worktable. A first support roller assembly and a second support roller assembly are sequentially arranged along the length of the top of the worktable. Each of the first and second support roller assemblies includes a first bracket and a second bracket, respectively. The first and second support rollers are hinged to the first and second brackets, respectively. The first and second support rollers are parallel to each other. Doorposts are located on the left and right sides of the worktable, and clamping mechanisms are correspondingly provided on the doorposts. Each clamping mechanism includes a guide seat, a guide rail, a roller seat, and a clamping roller. The guide seat is connected to the doorpost, and the guide rail is slidably connected to the guide seat. The guide rails of the two clamping mechanisms can move towards or away from each other. The roller seat is connected to the guide rail, and the clamping roller is hinged to the roller seat.

[0006] Preferably, the clamping mechanism also includes an adjusting bolt, a guide groove is provided along the length of the guide rail, an adjusting hole is provided on the guide seat opposite to the guide groove, the threaded section of the adjusting bolt passes through the guide groove and is threadedly connected to the adjusting hole, and its head abuts against the guide rail.

[0007] Preferably, there are two guide grooves, with each guide groove corresponding to a guide hole and an adjusting bolt.

[0008] Preferably, the roller seat has two opposing ear plates, and a mounting groove is formed between the two ear plates. The roller is clamped and embedded in the mounting groove, and both ends are hinged to the two ear plates respectively.

[0009] Preferably, the clamping roller is inclined along the first support roller assembly, and the angle between it and the horizontal plane is 60°.

[0010] Preferably, the first support roller assembly further includes an auxiliary positioning seat and a positioning rod. The auxiliary positioning seat is disposed on the first bracket, and the auxiliary positioning seat has positioning holes sequentially opened along the length direction. There are two positioning rods, and the two positioning rods are inserted into the positioning holes at any position.

[0011] Preferably, the positioning rod includes a front rod body and a rear rod body, with a stepped position formed at the mating position of the front rod body and the rear rod body. The front rod body matches the positioning hole, and the positioning rod is inserted into the positioning hole through the front rod body and abuts against the auxiliary positioning seat through the stepped position.

[0012] Preferably, the auxiliary positioning seat has a mounting surface, and a positioning hole is formed on the mounting surface, with the positioning hole inclined toward the clamping mechanism.

[0013] Preferably, the angle between the positioning hole and the horizontal plane is 60°.

[0014] Compared with the prior art, the advantages of this utility model are: This invention uses two sets of clamping mechanisms with corresponding clamping rollers in two symmetrical directions to clamp the steel strip coil, achieving axial positioning of the steel strip. This ensures a stable center of gravity during winding, counteracting the offset caused by high-speed rotation. Furthermore, the symmetrical mechanical clamping force maintains the axial position of the steel strip coil, eliminating the need for manual intervention throughout the process. This not only avoids the safety risks of operators coming into close contact with the steel strip coil but also overcomes the uneven force and visual observation errors inherent in manual support. It also prevents interlayer misalignment in the wound steel strip coil, ensuring the tightness and end-face uniformity of the winding. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0019] like Figures 1 to 5As shown, this utility model relates to a vertical winding machine for preventing steel strip coils from tipping over. It includes a workbench 1, with a first support roller assembly 2 and a second support roller assembly 3 sequentially arranged along the length of the top of the workbench 1. The first support roller assembly 2 and the second support roller assembly 3 each include a first bracket 201 and a second bracket 301. A first support roller 202 and a second support roller 302 are respectively hinged to the first bracket 201 and the second bracket 301. The first support roller 202 and the second support roller 302 are parallel to each other. The steel strip is placed on the first support roller 202 and the second support roller 302, and then... The rotating first support roller 202 and second support roller 302 are used for winding. The first support roller 202 and second support roller 302 are separated by a certain distance, thereby extending the support lever arm and providing higher anti-overturning stability for the steel strip coil 6 after it is coiled. Doorposts 4 are provided on the left and right sides of the workbench 1, and each doorpost 4 is equipped with a corresponding clamping mechanism 5. That is, there are two sets of clamping mechanisms 5. During the steel strip coil 6 winding operation, the two sets of clamping mechanisms 5 are located on the left and right sides of the steel strip, respectively. Each set of clamping mechanisms 5 includes a guide seat 501, a guide rail 502, a roller seat 503, and a clamping roller 504. The guide seat... 501 is connected to the gatepost 4, the guide rail 502 is slidably connected to the guide seat 501, the roller seat 503 is connected to the guide rail 502, and the clamping roller 504 is hinged to the roller seat 503. Two sets of clamping mechanisms 5 clamp the steel strip coil 6 in two symmetrical directions via corresponding clamping rollers, achieving axial positioning of the steel strip. This ensures the steel strip coil 6 maintains a stable center of gravity during winding, counteracting the offset generated during high-speed rotation. Furthermore, the axial position of the steel strip coil 6 is maintained through symmetrical mechanical clamping forces, eliminating the need for manual intervention throughout the process. This not only avoids the safety risks of operators having close contact with the steel strip coil 6 but also overcomes… To address the uneven force and visual observation errors inherent in manual support, this method avoids interlayer misalignment in the wound steel strip coil 6, ensuring its tightness and end-face uniformity. Furthermore, the rolling friction between the steel strip coil 6 and the clamping roller 504 during rotation reduces wear on the surface of the steel strip coil 6 and the working surface of the clamping roller 504. The guide rails 502 of the two clamping mechanisms 5 can move towards or away from each other, causing the connected roller seat 503 and clamping roller 504 to move closer or further apart, thereby dynamically adjusting the distance between the two clamping rollers 504 to adapt to steel strip coils 6 of different widths and improve the adaptability of the winding operation.

[0020] like Figures 3 to 5As shown, the clamping mechanism 5 also includes an adjusting bolt 505. The guide rail 502 has a guide groove 502a along its length. The guide seat 501 has an adjusting hole 501a opposite to the guide groove 502a. The guide groove 502a and the adjusting hole 501a are interconnected. The threaded section of the adjusting bolt 505 passes through the guide groove 502a into the adjusting hole 501a and is threadedly connected to the adjusting hole 501a. The diameter of the head section of the adjusting bolt 505 is larger than that of the guide groove 502a. The head section abuts against the outer wall of the guide rail 502 circumferentially around the guide groove 502a. Under the pressure of the head section of the adjusting bolt 505, the guide rail 502 will fit tightly against the guide seat 501 and lock with the guide seat 501, so that the guide rail 502, the roller seat 503 and the clamping roller 504 are kept in the adjusted position.

[0021] like Figure 3 and Figure 5 As shown, there are two guide grooves 502a. The guide grooves 502a correspond one-to-one with the guide holes and adjusting bolts 505. The stability of the guide rail 502 during the sliding process is improved by the two sets of adjusting bolts 505. After the adjustment is completed, the guide rail 502 is reliably fixed by double locking, avoiding the deflection or jamming problem of the guide rail 502 caused by single-point adjustment. This allows the guide rail 502 to have smooth linear displacement and rigid positioning at any position.

[0022] like Figure 4 As shown, two opposing ear plates 503a are formed on the roller seat 503, and an installation groove 503b is formed between the two ear plates 503a. The clamping roller 504 is embedded in the installation groove 503b, and both ends of the clamping roller 504 are respectively hinged to the two ear plates 503a. The ear plates 503a provide support to ensure the axial stability of the clamping roller 504 under stress conditions.

[0023] like Figure 8 As shown, the clamping roller 504 is inclined toward the first support roller assembly 2, and the angle between it and the horizontal plane is 60°, thereby increasing the overlap area between the clamping roller 504 and the steel strip coil 6, and correspondingly increasing the contact area with the steel strip coil 6, thus enhancing the stability of the positioning of the steel strip coil 6.

[0024] like Figure 1 , Figure 2 , Figure 6As shown in Figure 8, the first support roller assembly 2 also includes an auxiliary positioning seat 203 and positioning rods 204. The auxiliary positioning seat 203 is mounted on the first bracket 201. The auxiliary positioning seat 203 has positioning holes 203a sequentially opened along its length. The number of positioning holes 203a is not particularly limited, and the positioning holes 203a are arranged in a matrix. There are two positioning rods 204, which are inserted into the positioning holes 203a at any position. The positioning rods 204 can flexibly select the insertion point according to the specifications of the steel strip. The two sets of positioning rods 204 form an adjustable spacing limiting area through their cooperation with the positioning holes 203a. This limiting area is used for the insertion of the steel strip roll 6. With the cooperation of two sets of clamping mechanisms 5, symmetrical constraints are applied on both the front and rear sides of the rotation plane of the steel strip roll 6. This not only adapts to steel strip rolls 6 of different widths, but also effectively suppresses the offset of the steel strip roll 6, significantly improving the dynamic stability during high-speed winding.

[0025] like Figure 7 and Figure 8 As shown, the positioning rod 204 consists of two parts: a front rod body 204a and a rear rod body 204b. A step 204c is formed at the mating position of the front rod body 204a and the rear rod body 204b. The front rod body 204a matches the positioning hole 203a. The positioning rod 204 is inserted into the positioning hole 203a through the front rod body 204a and abuts against the auxiliary positioning seat 203 through the step 204c. Based on the above configuration, while realizing the quick insertion and removal positioning of the positioning rod 204, the step 204c ensures the axial accuracy after installation and avoids the positioning rod 204 from being over-inserted. The precise fit between the front rod body 204a and the positioning hole 203a forms radial positioning. The rear rod body 204b extends to the outside of the positioning hole 203a to facilitate the insertion and removal operation by the operator.

[0026] like Figure 6 As shown, the auxiliary positioning seat 203 has a mounting surface 203b and a positioning hole 203a is formed on the mounting surface 203b. The positioning hole 203a is inclined towards the clamping mechanism 5. In this way, when the positioning rod 204 is inserted into the positioning hole 203a through the front rod body 204a, it will be inclined towards the clamping mechanism 5. That is to say, the overlapping part between the positioning rod 204 and the rotating plane of the steel strip coil 6 is increased, and the contact area with the steel strip coil 6 is increased accordingly, thereby enhancing the stability of the positioning of the steel strip coil 6.

[0027] like Figure 8 As shown, the angle between the positioning hole 203a and the horizontal plane is 60°, thus keeping it parallel to the clamping roller shaft 504 of the clamping mechanism 5. In other words, the positioning hole 203a and the positioning rod 204 inserted in the positioning hole 203a form an inclination angle that matches the clamping mechanism 5, further enhancing the stability of the positioning of the steel strip coil 6.

[0028] Combination Figures 1 to 8In the steel strip coil anti-tipping vertical winding machine of this utility model, when performing steel strip winding operation, the steel strip coil 6 is first placed on the first support roller shaft 202 and the second support roller shaft 302 of the first support roller shaft assembly 2 and the second support roller shaft assembly 3. Then, the two sets of clamping mechanisms 5 on the two gate pillars 4 are controlled to release the abutment state between the clamping mechanism 5 adjusting bolt 505 and the corresponding guide rail 502. At this time, the guide rail 502 slides towards each other in the horizontal direction, thereby driving the roller shaft seat 503 and the clamping roller shaft 504 to move closer to each other. The clamping roller shaft 504 clamps the steel strip coil 6 from the left and right directions. At the same time, two positioning rods 204 are used, and their front rod bodies 204a are inserted into the positioning holes 203a of the auxiliary positioning seats 203 on both sides of the steel strip coil 6, so that the positioning rods 204 and the clamping roller shaft 504 of the clamping mechanism 5 maintain the same inclination angle, and together perform axial positioning of the steel strip coil 6.

[0029] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
