Description

Technical Field

[0001] This application relates to the field of steel plate coiling technology, and more specifically, to an anti-eccentric steel plate coiling and uncoiling machine. Background Technology

[0002] After the steel plates are leveled and cut, for some workpieces that need to go through subsequent processing or storage and transportation, a coiling machine is needed to roll them into regular steel coils. This reduces space occupation and avoids scratches and deformation of the steel plates during circulation, ensuring the quality of subsequent use.

[0003] In related technologies, to address the problem of steel strip loosening during winding, patent CN221821406U provides a rapid steel coil winding device. This device uses a winding roller located at the top of the base. During winding, the steel coil is inserted into a fastening groove, and the clamping plate is moved by rotating the bolts. During the movement, the steel plate inserted into the fastening groove is clamped and fixed. After fixing, the winding motor is started to drive the winding roller to rotate and wind the steel plate. After winding, the nuts are unscrewed from the screw, thereby separating the mounting plates at both ends of the winding roller from the drive shaft. After separation, the winding roller can be disassembled from the support plate, facilitating the installation and fixing of the winding roller. After fixing, the winding roller remains fixed to the steel plate, improving the stability and efficiency of steel plate winding.

[0004] Although the existing technical solutions mentioned above improve the stability of steel plate winding by fixing the steel plate with clamps, the steel plate needs to be unwound from one side of the winding roller after winding is completed. The winding roller is only supported by the drive structure. After long-term use, the equipment will be subjected to uneven stress, and one side will settle severely. This will cause the winding machine to malfunction due to eccentric force and require regular correction. However, because the equipment is heavy and fixed to the ground, it is difficult to correct it accurately.

[0005] In view of this, we propose an anti-eccentric steel plate coiling and uncoiling machine. Utility Model Content

[0006] The purpose of this application is to provide an anti-eccentric steel plate coiling and uncoiling machine, which can effectively solve the problem in the prior art that uncoiling must be carried out from one side of the coiling roller, resulting in the coiling roller relying solely on a single drive structure for support. Over long-term use, uneven force can easily lead to severe unilateral settlement, which in turn causes the coiling machine to generate eccentric force and fail to work properly. The application achieves the effect of supporting the steel coil to balance the force on the coiling roller, avoiding unilateral settlement, and eliminating the impact of eccentric force on the operation of the equipment.

The support blocks are driven to rise by external force to support the coiled steel plate body. Hydraulic cylinder B, located on one side of the take-up roller, is used to drive the limit ring plate to move and unwind the steel coil body.

[0008] As an optional solution to the technical solution of this application, the take-up roller is fixedly mounted on the output end of the hydraulic motor, the hydraulic motor is fixedly mounted on the inner side of the support base, the support base is fixedly mounted on the top of the working base plate, and the end of the take-up roller away from the hydraulic motor is supported by a support arm.

[0009] As an optional solution to the technical solution in this application, the hydraulic motor has a slot on its inner side for fixing one side of the steel plate.

[0010] As an optional solution to the technical solution of this application, U-shaped blocks are fixedly provided on both sides of the limiting ring plate, the support block is fixedly provided at the output end of the hydraulic cylinder A, and the hydraulic cylinder A is fixedly provided on the outside of the corresponding U-shaped block.

[0011] As an optional solution to the technical solution in this application, a rubber pad is fixedly provided on the top of the support block to prevent scratching the steel plate coil body.

[0012] As an optional solution to the technical solution of this application, a connecting seat is fixedly provided at the bottom of the limiting ring plate near the hydraulic motor. A slide rail A is provided on the side of the connecting seat away from the hydraulic motor. A slider A is slidably provided on the inner side of the slide rail A.

[0013] As an optional solution to the technical solution of this application, the hydraulic cylinder B is fixedly installed on the top of the working base plate, and a connecting plate is fixedly installed at the output end of the hydraulic cylinder B. The connecting plate is fixedly installed with a U-shaped block near the hydraulic motor. A slider B is fixedly installed at the bottom of the connecting seat. The slider B is slidably installed on the inner side of the slide rail B, and the slide rail B is fixedly installed on the top of the working base plate.

[0014] 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 two limiting ring plates and four support blocks. During winding, the two limiting ring plates limit the steel plate coil body, which facilitates the winding of the steel plate. After winding, the four hydraulic cylinders A push the corresponding support blocks to support the steel plate coil body, so that the support arm rotates and retracts automatically. Then, the hydraulic cylinder B pulls the two limiting ring plates to push the steel plate coil body to move and perform the unwinding action. Therefore, it effectively solves the problem in the prior art that unwinding must be carried out from one side of the winding roller, which causes the winding roller to rely on a single drive structure for support. After long-term use, it is easy to cause severe settlement on one side due to uneven force, which in turn causes the winding machine to generate eccentric force and fail to work normally. It achieves the effect of supporting the steel coil to balance the force on the winding roller, avoid eccentric settlement, and eliminate the impact of eccentric force on the operation of the equipment.

[0015] (2) This application provides a slide rail A on the inner side of the support base and pushes the limiting ring plate on one side to move by an electric push rod, so that the slider A and the slide rail A slide together, thereby changing the distance between the two limiting ring plates, thus making it suitable for steel plates of different specifications.

Detailed Implementation

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

[0018] Reference Figure 1 and Figure 2This application discloses an anti-eccentric steel plate coiling and uncoiling machine, including a coiling roller 1. The coiling roller 1 is driven to rotate by an external force to coil the steel plate coil body 100. Limiting ring plates 2 are provided on both sides of the coiling roller 1. Support blocks 3 are provided on both sides of the limiting ring plates 2. The support blocks 3 are driven to rise by an external force to support the coiled steel plate coil body 100. A hydraulic cylinder B4 is provided on one side of the coiling roller 1 to drive the limiting ring plates 2 to move and uncoil the steel plate coil body 100.

[0019] When the equipment is in use, the steel plate is wound up by the rotation of the winding roller 1. During the winding process, the limiting ring plates 2 on both sides are used to prevent the steel plate from shifting. After the winding is completed, the support block 3 provides support for the steel plate coil body 100 from below, balancing the force on the winding roller 1. Finally, the hydraulic cylinder B4 pushes the limiting ring plate 2 to realize the double-sided auxiliary unwinding of the steel plate coil body 100, solving the problem of uneven force caused by single-sided unwinding.

[0020] Reference Figure 1 and Figure 2 The take-up roller 1 is fixedly installed at the output end of the hydraulic motor 11. The hydraulic motor 11 is fixedly installed inside the support base 111. The support base 111 is fixedly installed on the top of the working base plate 5. The end of the take-up roller 1 away from the hydraulic motor 11 is supported by the support arm 12. A slot 13 is provided on the inner side of the hydraulic motor 11 for fixing one side of the steel plate.

[0021] Before winding, the support arm 12 is flipped to the support position so that the end of the winding roller 1 away from the hydraulic motor 11 is supported. Then, the first end of the steel plate to be wound is inserted into the slot 13, and the hydraulic motor 11 is started. The hydraulic motor 11 drives the winding roller 1 to rotate at a constant speed to wind the steel plate coil body 100.

[0022] Reference Figure 1 and Figure 3 Both sides of the limiting ring plate 2 are fixedly provided with U-shaped blocks 21, the support block 3 is fixedly provided at the output end of the hydraulic cylinder A31, the hydraulic cylinder A31 is fixedly provided on the outside of the corresponding U-shaped block 21, and the top of the support block 3 is fixedly provided with a rubber pad 32 to prevent scratching the steel plate coil body 100.

[0023] When the steel plate coil body 100 is wound to the set diameter, the hydraulic motor 11 stops rotating. At this time, the four hydraulic cylinders A31 are started simultaneously. The hydraulic cylinders A31 push the support block 3 to move upward until the rubber pad 32 is tightly attached to the outer surface of the steel plate coil body 100. The support block 3 forms four-point symmetrical support for the steel plate coil body 100, distributing the weight borne by the winding roller 1 and preventing the winding roller 1 from settling due to unilateral force.

[0024] Reference Figure 1 , Figure 3 and Figure 4A connecting seat 22 is fixedly installed at the bottom of the limiting ring plate 2 near the hydraulic motor 11. A slide rail A221 is installed on the side of the connecting seat 22 away from the hydraulic motor 11. A slider A222 is slidably installed on the inner side of the slide rail A221. The slider A222 is fixedly installed on the outer side of the corresponding limiting ring plate 2. The bottom of the limiting ring plate 2 is fixedly installed at the output end of the electric push rod 23. The electric push rod 23 is fixedly installed at the bottom of the connecting seat 22. A mounting plate 223 is fixedly installed on one side of the slide rail A221 by screws.

[0025] According to the width of the steel plate to be coiled, start the electric push rod 23. The electric push rod 23 pushes the limiting ring plate 2 on one side to slide along the slide rail A221 until the distance between the two limiting ring plates 2 matches the width of the steel plate. Then, turn off the electric push rod 23 and lock the position of the limiting ring plate 2 to ensure that the steel plate always moves between the two limiting ring plates 2 during the coiling process, avoiding the problem of eccentric coiling.

[0026] Reference Figure 1 and Figure 3 Hydraulic cylinder B4 is fixedly installed on the top of the working base plate 5. A connecting plate 41 is fixedly installed at the output end of hydraulic cylinder B4. The connecting plate 41 is fixedly installed with a U-shaped block 21 near the hydraulic motor 11. A slider B24 is fixedly installed at the bottom of the connecting seat 22. The slider B24 is slidably installed on the inner side of the slide rail B25. The slide rail B25 is fixedly installed on the top of the working base plate 5.

[0027] Before uncoiling, hydraulic cylinder B4 is activated. Hydraulic cylinder B4 pushes the limiting ring plate 2 near the hydraulic motor 11 via connecting plate 41. The slider B24 at the bottom of the limiting ring plate 2 slides along the slide rail B25. At the same time, the limiting ring plate 2 on the other side moves synchronously under the connection of electric push rod 23 and connecting seat 22. The two limiting ring plates 2 work together to push the steel plate coil body 100 out of the winding roller 1, realizing double-sided assisted uncoiling, avoiding the winding roller 1 being subjected to force on one side, and reducing the risk of the steel plate coil body 100 shifting during the uncoiling process.

[0028] In summary, when using the anti-eccentric steel plate coiling and uncoiling machine disclosed in this application embodiment, the electric push rod 23 is first started according to the width of the steel plate to be coiled. The electric push rod 23 pushes the limiting ring plate 2 on one side to slide along the slide rail A221 until the distance between the two limiting ring plates 2 matches the width of the steel plate. Then the electric push rod 23 is turned off, and the position of the limiting ring plate 2 is locked to ensure that the steel plate always moves between the two limiting ring plates 2 during the coiling process. Then, the support arm 12 is flipped to the support position so that the end of the winding roller 1 away from the hydraulic motor 11 is supported. Then, the first end of the steel plate to be wound is inserted into the slot 13, the hydraulic motor 11 is started, and the hydraulic motor 11 drives the winding roller 1 to rotate at a constant speed to wind up the steel plate coil body 100. After winding is completed, four hydraulic cylinders A31 are activated, the support block 3 rises to form four-point support for the steel plate coil body 100, the support arm 12 is retracted, and hydraulic cylinder B4 is activated. Hydraulic cylinder B4 pushes the limiting ring plate 2 near the hydraulic motor 11 through the connecting plate 41. The slider B24 at the bottom of the limiting ring plate 2 slides along the slide rail B25. At the same time, the limiting ring plate 2 on the other side moves synchronously under the connection of the electric push rod 23 and the connecting seat 22. The limiting ring plates 2 on both sides work together to push the steel plate coil body 100 out of the winding roller 1, realizing double-sided assisted unwinding, avoiding the winding roller 1 being subjected to force on one side, and reducing the risk of the steel plate coil body 100 shifting during the unwinding process.
