Technical Field

[0001] This utility model relates to the field of unwinding machine technology, specifically to an unwinding machine drum clamping mechanism. Background Technology

[0002] Unwinding machines are core equipment used in industrial production for the continuous release of rolled materials. When clamping lightweight rolls that require frequent loading and unloading, workers need to lift the material and then work with the clamping and feeding device to connect the end of the roll to the corresponding turntable support key. In this process, manual lifting is time-consuming and laborious. If the lifting is not stable, the roll may fall and the material on the roll may become loose, making it inconvenient to use. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a winding machine drum clamping mechanism.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a winding machine drum clamping mechanism, comprising a material roll, a fixed support assembly, a support platform, and a movable support assembly.

The movable support assembly includes a feeder, a movable plate, and a second rotating bearing member. A feeder that drives the movable plate to move is provided on the support platform. The second rotating bearing member is rotatably provided on the movable plate. Both ends of the material roll are respectively inserted into the first and second rotating bearing members. An inverted L-shaped mounting plate is provided on the adjacent sides of the movable plate and the fixed plate. A lifting member for assisting in lifting the material roll is provided on the mounting plate.

[0005] To facilitate adjustment of the height of the roller end, this utility model is improved by including a lifting device, a lifting plate, a base plate, and a lifting frame. The output end of the lifting device passes through the top wall of the mounting plate and is connected to the lifting plate. The base plate is connected to the lifting plate below through a connector. A V-shaped lifting frame is also provided on the base plate, and the two free ends of the lifting frame are arc-shaped.

[0006] To ensure the strength of the support frame, this utility model is improved by providing reinforcing ribs on the base plate that are connected to the support frame.

[0007] Preferably, the connector includes a positioning post, a stud, and a nut. The positioning post is provided at the four corners below the base plate, and the lifting plate is provided with positioning holes adapted to the positioning post.

[0010] (III) Beneficial Effects Compared with the prior art, the present invention provides a winding machine drum clamping mechanism, which has the following advantages: The unwinding machine's drum clamping mechanism uses a "lifter + V-shaped lifting frame" to automatically lift the material roll: the operator only needs to place the material roll on the lifting frame (no lifting required), and start the lifter to adjust the height of the material roll so that both ends of the material roll are precisely aligned with the first key roller and the second key roller. The entire process does not require continuous manual lifting, solving the core pain point of traditional clamping being "time-consuming and labor-intensive". The lifting frame has an arc-shaped design at both free ends, which facilitates the quick placement of the material roll and avoids scratching the surface of the material roll, making it suitable for lightweight material rolls.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4 A winding machine drum clamping mechanism includes a material roll 1, a fixed support assembly, a support platform 2, and a movable support assembly. The fixed support assembly is located at one end of the support platform 2. The fixed support assembly includes a fixed plate 3, a first motor 4, and a first rotating bearing member. The fixed plate 3 is connected to the support platform 2 at its lower end. The first rotating bearing member is located on the fixed plate 3. The output end of the first motor 4 passes through the fixed plate 3 and is connected to the first rotating bearing member. The movable support assembly includes a feeder, a movable plate 5, and a second rotating bearing member. The support platform 2 has a feeder that moves the movable plate 5. The second rotating bearing member is rotatably mounted on the movable plate 5. Both ends of the material roll 1 are respectively inserted into the first and second rotating bearing members. An inverted L-shaped mounting plate 6 is located on the adjacent sides of the movable plate 5 and the fixed plate 3. A lifting member for assisting in lifting the material roll 1 is located on the mounting plate 6.

[0015] In this embodiment, the lifting component includes a lifter 7, a lifting plate 8, a base plate 9, and a lifting frame 10. The output end of the lifter 7 passes through the top wall of the mounting plate 6 and is connected to the lifting plate 8. The base plate 9 is connected to the lifting plate 8 via a connector. The base plate 9 is also provided with a V-shaped lifting frame 10. The two free ends of the lifting frame 10 are arc-shaped. When the pusher is activated, the pusher drives the moving plate 5 to move towards the fixed plate 3, so that the two sets of lifting frames 10 can stably lift the material roller. The operator does not need to lift the material roll 1. He / she only needs to place the lightweight material roll 1 (such as film roll or paper roll) directly on the V-shaped lifting frame 10 on both sides of the mounting plate 6. The lifting frame 10 has a V-shaped structure and automatically centers the material roll 1 by gravity to avoid the material roll 1 from shifting when placed. The arc design of its two free ends reduces the difficulty of placing the material roll 1 and prevents scratches on the surface of the material roll 1. The lifting device 7 of the lifting component is activated. In this embodiment, the lifting device 7 is a hydraulic cylinder. The two sets of hydraulic cylinders are controlled by a servo control system, so that the extension rods of the two sets of hydraulic cylinders push the lifting plate 8 to move in the vertical direction, thereby driving the base plate 9 and the lifting frame 10 to rise and fall synchronously, so that the material roll 1 is in a horizontal state. Make sure that the center axes of both ends of the material roll 1 are aligned with the center axes of the first key roller 16 and the second key roller 18, in preparation for subsequent insertion.

[0016] In this embodiment, the connector includes positioning posts 12, studs 13, and nuts 14. Positioning posts 12 are provided at the four corners of the lower part of the base plate 9. Positioning holes adapted to the positioning posts 12 are provided on the lifting plate 8. A stud 13 passing through the positioning hole is provided below the positioning post 12. The stud 13 is connected to the nut 14 below. The positioning posts 12 below the base plate 9 are inserted into the positioning holes of the lifting plate 8 and locked with the stud 13 and nut 14 to ensure that the base plate 9 and the lifting plate 8 are firmly connected and there is no shaking during the lifting process. The base plate 9 is also provided with reinforcing ribs 11 connected to the lifting frame 10. The reinforcing ribs 11 on the base plate 9 are integrally connected with the V-shaped lifting frame 10 and are distributed in a triangular shape to enhance the load-bearing rigidity of the lifting frame 10, which can stably support the lightweight material roll 1 and avoid deformation after long-term use.

[0017] In this embodiment, the first rotating support includes a first turntable 15 and a first key roller 16. The first turntable 15 is rotatably connected to the fixed plate 3. The first key roller 16, which is inserted into the material roll 1, is disposed at the center of the first turntable 15. The second rotating support includes a second turntable 17 and a second key roller 18. The second turntable 17 is rotatably connected to the moving plate 5. The second key roller 18, which is inserted into the other end of the material roll 1, is disposed at the center of the second turntable 17. The feeder includes a slide frame 19, a slide rail 20, a screw 21, a second motor 22, and a slider 23. The support plate is symmetrically provided with slide rails 20 on both the front and rear sides. The moving plate 5 is provided with a guide groove connected to the slide rails 20 below it. The support plate is also provided with a slide frame 19. The slide frame 19 is provided with a slide groove with an opening at the top. The screw 21 is rotatably disposed in the slide groove. The slider 23, which is threadedly connected to the screw 21, is also disposed in the slide groove. The output end of the second motor 22 passes through the slide frame 19 and is connected to the screw 21. Next, the slider 23 is connected to the moving plate 5 above. The second motor 22 of the feeder is started, and its output end drives the screw 21 in the slide frame 19 to rotate. The screw 21 is threadedly connected to the slider 23, converting the rotational motion into the horizontal linear motion of the slider 23. The slider 23 is fixedly connected to the moving plate 5 above. The guide groove below the moving plate 5 slides with the slide rail 20 of the support platform 2, restricting the radial movement of the moving plate 5 and ensuring that the moving plate 5 moves smoothly in the horizontal direction. When the moving plate 5 moves, it drives the second rotating bearing (second turntable 17 + second key roller 18) above to move closer to the material roll 1, so that the second key roller 18 is accurately inserted into one end of the material roll 1. The other end of the material roll 1 is pre-aligned with the first key roller 16 of the fixed support assembly. With the insertion of the second key roller 18, the material roll 1 is clamped between the first key roller 16 and the second key roller 18, completing the clamping. The first key roller 16 and the second key roller 18 both adopt spline structure and are tightly fitted with the keyway at the end of the material roll 1 to ensure stable torque transmission and no relative slippage during unwinding. In this embodiment, the first motor 4 and the second motor 22 are servo motors. Depending on the requirements, elastic dust covers connected to the side walls of the slide frame 19 can be added to the left and right ends of the slider 23 to ensure its stability. Alternatively, staff can perform regular maintenance and inspection, apply grease to the screw 21, or clean it with an air gun regularly to ensure the stability of the transmission between the slider 23 and the screw 21.
