Description

Technical Field

[0001] The utility model relates to the technical field of material winding, and more particularly to a pressing mechanism of a winding device. Background Art

[0002] The winding device is a device that mechanically rolls raw materials into coils. It is widely used in industrial production, especially in coil processing production lines, such as paper rolls, cloth rolls, plastic rolls, metal coils, etc. In order to prevent the material from becoming loose during the winding process, a clamping mechanism is set to keep the material taut and ensure the material tension.

[0003] Based on the above, the inventors found that the existing clamping mechanism is mainly composed of a driving member and a clamping roller, but the reset, installation and disassembly of the output end connection structure between the clamping roller and the driving member are inconvenient, and it is not convenient to repair and maintain the clamping roller in the later stage. Therefore, in view of this, the inventors studied and improved the existing structure and provided a clamping mechanism for a winding device in order to achieve a more practical purpose.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figure 1-4 A clamping mechanism of a winding device includes a fixed frame 2 and a winding frame 1. A pair of cylinders 3 are fixedly connected to the top surface of the fixed frame 2. The output end of the cylinder 3 passes through the fixed frame 2 and is fixedly connected to a telescopic rod 4. A clamping shaft 5 is centrally provided on the opposite surfaces of the two telescopic rods 4. A limiting mechanism 6 is provided just above the clamping shaft 5. The bottom end of the telescopic rod 4 is threadedly connected to a threaded sleeve 7 on the outside. A connecting plate 8 is provided on one side of the threaded sleeve 7. The two ends of the connecting plate 8 are respectively fixedly connected to a movable ring 9 and a clamping ring 10.

[0028] The limiting mechanism 6 includes a screw rod 11, and two ball sliders 12 are sleeved on the outer side of the screw rod 11. The bottom of the ball slider 12 is fixedly connected to a limiting plate 14, and the same guide rod 13 is provided through the upper opposite surfaces of the two ball sliders 12. In order to limit and prevent the winding material from deflecting, a limiting mechanism 6 is provided.

[0029] See Figure 2 The fixed frame 2 is located in front of the winding frame 1, and the horizontal height of the clamping shaft 5 is lower than the horizontal height of the middle part of the winding frame 1. One end of the material passes through the bottom of the clamping shaft 5 and is fixedly connected to the winding shaft in the middle part of the winding frame 1. The winding shaft rotates to carry out the winding work. During the winding process, if the material becomes loose, start the cylinder 3 to make the telescopic rod 4 drive the clamping shaft 5 to press down the material to restore the material to a taut state.

[0030] See Figure 3The cross-section of the two movable rings 9 is T-shaped, and the movable ring 9 is movably connected to the threaded sleeve 7. The threaded sleeve 7 is rotated to drive the connecting plate 8 to move as a whole. When the material passes under the clamping shaft 5, it rubs against the clamping shaft 5, driving the clamping shaft 5 to rotate as a whole. The rotation stability of the clamping shaft 5 is ensured by the movable ring 9 and the threaded sleeve 7.

[0031] See Figure 3 The two clamping rings 10 are respectively clamped with the two ends of the clamping shaft 5. The clamping shaft 5 is fixed between the two telescopic rods 4 through the clamping of the clamping rings 10 and the clamping shaft 5. Conversely, the clamping rings 10 are separated from the clamping shaft 5, and the clamping shaft 5 can be removed.

[0032] See Figure 4 The screw rod 11 is movably connected to the upper part of the telescopic rod 4, and the guide rod 13 is fixedly connected to the upper part of the telescopic rod 4. The screw rod 11 is rotated to ensure the movement stability of the ball slider 12 through the guide rod 13.

[0033] See Figure 4 The outer surface of the screw rod 11 is provided with two sections of rotating threads of the same length and opposite directions, and the two sections of rotating threads are respectively adapted to the two ball sliders 12. The screw rod 11 cooperates with the two sections of rotating threads so that the two ball sliders 12 respectively drive the two limit plates 14 to slide horizontally.

[0034] See Figure 4 The limiting plate 14 is sleeved on the outside of the pressing shaft 5, and the limiting plate 14 is movably connected to the pressing shaft 5. The limiting plate 14 moves to the outside of the pressing shaft 5 so that the two limiting plates 14 are respectively located on both sides of the material.

[0035] When the material passes under the pressing shaft 5, friction occurs with the pressing shaft 5, driving the pressing shaft 5 to rotate as a whole, and the rotation stability of the pressing shaft 5 is guaranteed by the movable ring 9 and the threaded sleeve 7.
