Abstract

The application discloses a steel coil winding roller, and belongs to the technical field of steel coil winding. The steel coil winding roller comprises a roller core, side plates arranged on the two sides of the roller core, and arc-shaped plates slidingly arranged between the two side plates. The arc-shaped plates are arranged in a ring array, and the inner side of each arc-shaped plate is provided with a clamping groove. A pressing plate is arranged on the inner side of the clamping groove and is driven by external force to fix one end of the steel plate. The application effectively solves the problem that the steel coil is easily clamped by the winding roller when the winding roller is unloaded by a side pushing device after winding is completed, which leads to low unloading efficiency and easily causes the edge of the steel plate to be scratched and the clamping groove of the winding roller to be worn. The application improves the unloading smoothness and reduces the loss of the steel plate and the winding roller.

Description

Technical Field

[0001] This application relates to the field of steel coil winding technology, and more specifically, to anti-jamming steel coil winding rolls. Background Technology

[0002] When steel plates are processed and produced, after leveling and cutting, some parts need to be coiled using a coiling machine to facilitate subsequent storage, transportation and further processing. The core component of the coiling machine is the coiling roller, which rotates under the drive of the drive equipment to coil the steel plate.

[0003] In related technologies, to address the inconvenience of installing and disassembling take-up rollers, for example, patent CN222833727U provides a take-up roller that facilitates the insertion and separation of the first and second shafts through the cooperation of a first rotating shaft, a first connecting block, a mounting hole, a second connecting block, bolts, nuts, and the second rotating shaft and the take-up roller. This greatly simplifies the installation and disassembly of the take-up roller. When the take-up roller needs to be replaced, simply loosen the bolts and nuts to separate the first and second connecting blocks, thus separating the two rotating shafts from the take-up roller. Then, connect the new take-up roller through the first and second connecting blocks to achieve the disassembly and replacement of the take-up roller. This effectively improves the convenience of the device and meets the user's needs.

[0004] Although the existing technical solutions mentioned above facilitate the disassembly and replacement of the take-up roller by setting bolts and nuts, when taking up the steel plate, the steel plate is fixed by the slot of the take-up roller and then taken up. After the take-up is completed, a side push device is required to push it out, but it is often stuck by the slot, which not only affects the unloading efficiency, but may also cause problems such as scratches on the edge of the steel plate and wear on the slot of the take-up roller.

[0005] In view of this, we propose an anti-jamming steel coil take-up roll. Utility Model Content

[0006] The purpose of this application is to provide an anti-jamming steel coil take-up roll, which can effectively solve the problem in the prior art that when the take-up roll is unloaded through the side push device after winding, the steel coil is easily jammed by the take-up roll gap, resulting in low unloading efficiency and easy to cause scratches on the steel plate edge and wear of the take-up roll gap. It achieves the effect of improving the smoothness of unloading and reducing the wear of steel plate and take-up roll.

[0007] This application provides an anti-jamming steel coil take-up roll, including: Roller core; Side plates are located on both sides of the roller core; An arc-shaped plate is slidably disposed between two side plates. Several arc-shaped plates are provided, and the several arc-shaped plates are arranged in a circular array. A slot is provided on the inner side of the arc-shaped plate. A pressure plate is located inside the slot, and the pressure plate is driven by an external force to fix one end of the steel plate.

[0008] As an optional solution to the technical solution of this application, threaded holes are provided on both sides of the slot, the pressure plate is driven to move by bolts, and the bolts are threaded to the threaded holes.

[0009] As an optional solution to the technical solution of this application, guide posts are fixedly provided on both sides of the slot, and the pressure plate is slidably disposed on the outside of the corresponding guide posts.

[0010] As an optional solution of the technical solution in this application, the inner side of the side plate is provided with an arc-shaped array of holes, and the two sides of the arc-shaped plate are fixedly provided with sliding pins corresponding to the arc-shaped holes, and the sliding pins are slidably disposed inside the arc-shaped holes.

[0011] As an optional solution to the technical solution of this application, a limiting plate is fixedly provided on the outer side of the sliding pin, and the diameter of the limiting plate is greater than the width of the arc-shaped hole.

[0012] As an optional solution to the technical solution of this application, both ends of the roller core are provided with patterned holes A, and the two side plates are provided with patterned holes B and mounting holes on the side that is far apart from each other.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: (1) This application uses an arc plate. By opening a slot on one side of the arc plate and setting a pressure plate inside the slot, the gap between the pressure plate and the slot is the slot. The steel plate is pressed into the slot by pushing the pressure plate with bolts, and the opening of the steel plate is fixed. When unloading, because there is a certain distance between the arc plate and the roller core, the operator can turn the bolt to make the slot larger and release the fixation on one end of the steel plate. Then the material is unloaded by the pushing mechanism. Therefore, it effectively solves the problem in the prior art that when the winding roller is unloaded by the side pushing device after winding, the steel coil is easily stuck by the winding roller slot, resulting in low unloading efficiency and easy to cause scratches on the edge of the steel plate and wear of the winding roller slot. It achieves the effect of improving the unloading smoothness and reducing the wear of steel plate and winding roller.

[0014] (2) In this application, the side plate is connected to the drive shaft of the external drive mechanism through the flower hole B on the side plate and the flower hole A on the roller core. The corresponding side plate is fixed to the drive shaft of the external drive mechanism through the mounting hole. The other side plate is supported by the external support arm, so the assembly of the winding machine can be completed. The setting of flower hole B and mounting hole facilitates the disassembly of the winding roller.

[0015] (3) By setting a sliding pin, the sliding pin is slidably set with the arc-shaped hole. After the corresponding side plate is fixed with the drive shaft of the external drive mechanism, the drive shaft can drive the corresponding side plate to rotate. When the steel plate is coiled, the drive shaft drives the side plate to rotate, thereby driving several arc-shaped plates to rotate to the outermost side. At this time, the arc-shaped hole limits the sliding pin. If the rotation continues, it will drive several arc-shaped plates to rotate to coil the steel plate. After the coiling is completed, the drive shaft rotates in the opposite direction to drive several arc-shaped plates to rotate, so that several arc-shaped plates can be separated from the inner side of the steel coil, which is convenient for subsequent unloading.

Guide column. Detailed Implementation

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figure 1 , Figure 2 and Figure 3 This application discloses an anti-jamming steel coil take-up roller, including a roller core 1, side plates 2 on both sides of the roller core 1, a plurality of arc plates 3 slidably arranged between the two side plates 2, and the plurality of arc plates 3 arranged in a circular array, a slot 31 is opened on the inner side of the arc plate 3, and a pressure plate 4 is arranged on the inner side of the slot 31. The pressure plate 4 is driven by an external force to fix one end of the steel plate.

[0019] The opening of the steel plate is placed into the slot 31, and then the pressure plate 4 is driven to move towards the steel plate. The opening of the steel plate is clamped and fixed by the cooperation between the pressure plate 4 and the inner wall of the slot 31. Then the external drive mechanism is started to drive the winding roller to rotate as a whole. Several arc plates 3 continuously wind up the steel plate during the rotation process to ensure that the opening of the steel plate will not loosen or shift during the winding process. After winding is completed, the drive pressure plate 4 moves away from the steel plate to release the fixation on the end of the steel plate, and then the material is unloaded through the external pushing mechanism, which improves the smoothness of unloading and reduces the wear of the steel plate and winding roller.

[0020] Reference Figure 2 and Figure 3 Both sides of the slot 31 are provided with threaded holes 32. The pressure plate 4 is driven to move by the bolt 41. The bolt 41 is threaded with the threaded hole 32. Both sides of the slot 31 are fixedly provided with guide posts 5. The pressure plate 4 is slidably provided on the outside of the corresponding guide post 5.

[0021] By rotating the bolt 41, the bolt 41 is pushed into the slot 31 and the pressure plate 4 is moved by the threaded engagement between the bolt 41 and the threaded hole 32. At the same time, the guide post 5 limits and guides the movement of the pressure plate 4, preventing the pressure plate 4 from deviating during the movement. This ensures that the pressure plate 4 can stably and evenly clamp the steel plate in the slot 31. The pressure plate 4 can also be retracted by rotating the bolt 41 in the opposite direction, quickly releasing the fixation of the steel plate.

[0022] Reference Figure 3 and Figure 4 The inner side of the side plate 2 has an arc-shaped hole 21 in an annular array. The two sides of the arc plate 3 are fixedly provided with sliding pins 33 corresponding to the arc-shaped hole 21. The sliding pins 33 are slidably provided inside the arc-shaped hole 21. The outer side of the sliding pins 33 is fixedly provided with a limiting plate 331. The diameter of the limiting plate 331 is greater than the width of the arc-shaped hole 21.

[0023] The side plate 2 is rotated by an external drive mechanism. During the rotation of the side plate 2, the inner wall of the arc hole 21 will exert a thrust on the sliding pin 33. Since the sliding pin 33 is fixedly connected to the arc plate 3 and the sliding pin 33 can slide along the arc hole 21, the arc plate 3 will move away from the roller core 1 under the action of the thrust until the sliding pin 33 slides to the outermost limit of the arc hole 21. At this time, several arc plates 3 form a cylindrical surface that is adapted to the coiling of the steel plate. After winding is completed, the drive side plate 2 rotates in the opposite direction, and the arc hole 21 drives the sliding pin 33 to slide towards the roller core 1, so that the arc plate 3 contracts and separates from the inside of the steel coil, which facilitates subsequent unloading. The limiting plate 331 can prevent the sliding pin 33 from falling out of the arc hole 21, ensuring the stability of the structure operation.

[0024] Reference Figure 2 and Figure 4 Both ends of the roller core 1 are provided with perforated holes A11, and the two side plates 2 are provided with perforated holes B22 and mounting holes 23 on the side that is far apart from each other.

[0025] By connecting the drive shaft of the external drive mechanism to the flower hole B22, it is ensured that the drive mechanism can stably drive the side plate 2 to rotate. At the same time, screws and other tools are used to fix the side plate 2 to the drive shaft of the external drive mechanism through the mounting hole 23, further improving the connection stability. The perforation A11 can be used as a backup connection structure. When the equipment does not need to use the side plate 2 and the arc plate 3, the side plate 2 and the arc plate 3 can be removed from the outside of the roller core 1. When the roller core 1 needs to be driven or positioned, it can be connected to the external components through the perforation A11 to enhance the applicability and flexibility of the device.

[0026] In summary, when using the anti-jamming steel coil take-up roller disclosed in this application embodiment, the take-up roller is first assembled and fixed with the external drive mechanism and support arm through the perforated hole B22 and the mounting hole 23; Next, place the steel plate end into the slot 31, rotate the bolt 41 to push the pressure plate 4 and cooperate with the guide column 5 to limit the position, thus clamping the steel plate end. Then the drive mechanism is started, which drives the side plate 2 to rotate. The arc plate 3 unfolds through the cooperation of the arc hole 21 and the sliding pin 33, and the steel plate is wound up as the winding roller rotates. After winding is completed, the reverse rotation of bolt 41 causes pressure plate 4 to retract, releasing the fixation on the opening of the steel plate, driving side plate 2 to rotate in the opposite direction, causing arc plate 3 to retract and detach from the inside of the steel coil, and finally the steel coil is smoothly pushed out for unloading through the side push device. The whole process not only ensures the stability of winding, but also effectively avoids the problem of unloading jamming. At the same time, the convenient assembly structure facilitates the disassembly and maintenance of the winding roller.
