Description

Technical Field

[0001] The utility model relates to cable production equipment, in particular to a rotating disk traction device. Background Art

[0002] In the production of cable wrapping or twisting, the material is generally discharged through the material tray, so that the cable or tape is led to the rotating disk, and then the rotating disk is driven to rotate by the driving device, so that the cable or tape is continuously discharged or wrapped. When the cable or tape passes through the other side of the rotating disk, it is necessary to set a traction wheel and a pressure wheel for traction, so as to ensure the material is output at a stable and uniform speed through traction. However, in actual application, when the equipment is shut down, it takes a certain time for the material tray and the rotating disk to completely stop rotating. During this time, the material tray and the rotating disk are in an out-of-control state. The material tray will still release a length of material, and the rotating disk will also drive the material to rotate, so that the material is continuously wound on the traction wheel, so that multiple layers of material are accumulated between the traction wheel and the pressure wheel. Since the pressure wheel in the existing equipment is positioned on one side of the traction wheel through the central axis, and the gap between the pressure wheel and the traction wheel is fixed, therefore, when the material between the traction wheel and the pressure wheel accumulates to a certain thickness, it is easy for the traction wheel or the central axis of the pressure wheel to be damaged by a large pressure, thereby causing damage to the equipment, increasing the maintenance time and cost of the equipment, and being unfavorable to production.

The seat body 21 is cylindrical and one side is provided with an opening to expose the wheel surface of the take-up wheel 22, so that the inside of the seat body 21 has an annular guiding function, making it more convenient and quick to thread the material; in addition, this can form a protection for the take-up wheel 22, which is conducive to reducing wind resistance. The elastic component 25 is arranged on the rotating disk 1 and can provide an elastic force to the swing seat 23 to drive the swing seat 23 to approach the seat body 21, so that the wheel surface of the pressure wheel 24 and the wheel surface of the take-up wheel 22 are in rolling contact with a certain resistance force. The output end of the take-up drive component 26 is connected to the take-up wheel 22 to drive the take-up wheel 22 to rotate, and drive the material to pass through the first steering wheel 3, between the wheel surface of the take-up wheel 22 and the wheel surface of the pressure wheel 24, and the second steering wheel 4 and then output outward. A counterweight 12 is provided on the side of the rotating disk 1 opposite to the pressure wheel take-up mechanism 2 to make the rotating disk 1 more stable when rotating.

[0024] Please see again Figure 1 and Figure 2The rotating disk traction device 100 further includes a rotating shaft 5, the rotating disk 1 is fixed to one end of the rotating shaft 5, and the rotating shaft 5 is arranged on the bearing seat 6 through a bearing 61. The rotating shaft 5 is provided with a material passing groove 51 along the axial direction, and the material passing groove 51 deviates from the center of the rotating shaft 5.

By providing the rotating shaft 5, support can be provided for the rotating disk 1, so that the rotating disk 1 can rotate around its own central axis, thereby realizing twisting or wrapping.

[0025] For example Figures 4 to 7 As shown, an end cover 211 is provided at one end of the seat body 21 away from the rotating disk 1, and a pivot shaft 231 is provided between the end cover 211 and the seat body 21, and the upper end of the swing seat 23 is swingably provided on the seat body 21 through the pivot shaft 231.

[0026] Please see again Figure 6 The elastic component 25 includes an adjusting screw 251 and an elastic member 252. The rotating disk 1 is provided with a bracket 11. The adjusting screw 251 is threadedly connected to the bracket 11 and one end of the adjusting screw 251 abuts against one end of the elastic member 252. The other end of the elastic member 252 elastically abuts against the swing seat 23. By adjusting the compression length of the elastic member 252 by using the adjusting screw 251, the elastic force of the elastic member 252 can be adjusted, so that the pressure of the pressing wheel 24 against the drawing wheel 22 is adjustable, so as to be suitable for different materials. The elastic member 252 can be a compression spring or an elastic silicone.

[0027] For example Figure 2 As shown, the taking-in drive assembly 26 includes a taking-in motor 261, a first active synchronous wheel 262, a first driven synchronous wheel 263, a first synchronous belt 264, a first gear 265 and a second gear 266.

[0028] For example Figure 2 As shown, the rotating disk traction device 100 further includes a spindle drive mechanism 7, the output end of which is connected to the rotating shaft 5 to drive the rotating shaft 5 to rotate around its own central axis. The spindle drive mechanism 7 includes a drive motor 71, a second active synchronous wheel 72, a second driven synchronous wheel 73 and a second synchronous belt 74, the output end of the drive motor 71 is connected to the second active synchronous wheel 72, the second driven synchronous wheel 73 is connected to the rotating shaft 5, and the second synchronous belt 74 is wound between the second active synchronous wheel 72 and the second driven synchronous wheel 73.

[0029] Combining the above and Figure 2 The working principle of the rotary disk traction device 100 of the utility model is described in detail below:

[0030] First, the material passes through the center of the rotating disk 1 from the material trough 51, then bypasses the first steering wheel 3, and then bypasses the drawing wheel 22, so that the pressing wheel 24 presses the material against the surface of the drawing wheel 22. The material then bypasses the second steering wheel 4 and is output to the outside. When conveying the material, the drawing motor 261 is started to drive the first active synchronous wheel 262, the first active synchronous wheel 262 drives the first driven synchronous wheel 263 through the first synchronous belt 264, the first driven synchronous wheel 263 drives the first gear 265, the first gear 265 drives the second gear 266, and the second gear 266 drives the drawing wheel 22 to rotate. At this time, the drawing wheel 22 drives the material to run to achieve material feeding.

[0031] When the rotary disk traction device 100 of the utility model is used for tape wrapping, the material is tape wrapping, and the core wire is passed through the through hole in the center of the rotating shaft 5 from one end to the other end, and the core wire can be driven to feed the material through another drawing device. Afterwards, the drive motor 71 starts to drive the second active synchronous wheel 72, and the second active synchronous wheel 72 drives the second driven synchronous wheel 73 through the second synchronous belt 74, and the second driven synchronous wheel 73 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the rotating disk 1 to rotate. At this time, the material rotates around the central axis of the rotating disk 1 while being drawn by the drawing wheel 22, so that the material is wrapped around the core wire to achieve tape wrapping. Similarly, the rotary disk traction device 100 of the utility model can also be used for stranded wire, and the working principle is the same, which will not be repeated here.

[0032] Compared with the prior art, the utility model provides a swing seat 23 on the rotating disk 1 and a pressure wheel 24 on the swing seat 23, and the swing seat 23 swings so that the pressure wheel 24 can be close to or away from the drawing wheel 22, so that the pressure wheel 24 can be adjusted relative to the drawing wheel 22. The elastic component 25 is pressed against the swing seat 23, so that there is a certain elastic pressure between the pressure wheel 24 and the drawing wheel 22, so that the gap between the pressure wheel 24 and the drawing wheel 22 for the material to pass through is adaptively adjusted, thereby avoiding the accumulation of materials between the pressure wheel 24 and the drawing wheel 22, and not generating excessive additional loads on the pressure wheel 24 and the drawing wheel 22 due to the change in the thickness of the material, preventing the pressure wheel 24 and the drawing wheel 22 from being crushed, effectively protecting the pressure wheel 24 and the drawing wheel 22, reducing the number of equipment maintenance, and thus reducing production costs.

[0033] The above disclosure is only a preferred example of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
