Description

Technical Field

[0001] The utility model relates to a cable production device, in particular to a long-life cable winding device. Background Art

[0002] During the cable production process, the processed cables need to be rolled up and stored for transfer or transportation. Rolling generally uses a winding roller, which is rotatably mounted on a drive device and driven by a drive mechanism to rotate for winding operations. In order to prevent the cable from accumulating on a part of the winding roller during winding, a guide mechanism is generally provided to guide the cable. The guide mechanism moves back and forth along the axis of the winding roller so that the cable is neatly and evenly wound on the winding roller. However, in this process, there is still a problem that is easily overlooked, that is, the height of the guide mechanism is fixed, but the outer diameter of the winding drum is increasing as the winding proceeds. Therefore, the height of the cable close to the winding drum gradually increases, and the surface of the cable is prone to friction with the guide components in the guide mechanism, which leads to component wear and shortens the service life of the components.

[0003] In the prior art, a Chinese patent with publication number CN219116825U discloses a cable reel, including a mounting plate, a rotating shaft movably connected to the mounting plate through a bearing, and a reeling column is fixedly connected to the end of the rotating shaft away from the mounting plate, and a guiding mechanism is provided on the mounting plate, and the guiding mechanism includes a fixed block, a fixed block is fixedly connected to the lower side of the front end of the mounting plate, and a reciprocating screw rod is movably connected to the inside of the fixed block through a bearing, and a reciprocating sleeve block is sleeved on the right side of the outside of the reciprocating screw rod, and an adjusting cleaning mechanism is provided on the mounting bottom plate. This technical solution can guide the cable so that the cable is evenly wound on the reel. However, in this technical solution, a limit ring is used to guide the cable, and the position of the limit ring cannot be adjusted during the guiding process. Therefore, during the reeling process, as the reeling action continues, the outer diameter of the reel gradually increases, and friction will occur between the cable to be reeled when passing through the limit ring. Long-term use will cause the limit ring to wear and even damage. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] It should be noted that, in the description of the technical solution of the present invention, some directional words used to clearly describe the technical features of the present invention, such as "front", "back", "up", "down", "top", "bottom", "inside", "outside", etc., are all in accordance with the orientation of the drawings of the present invention.

[0021] Example

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a long-life cable winding device of this embodiment includes a guide mechanism and a winding mechanism 1 that are spaced apart along the direction of cable travel. The winding mechanism 1 includes a rotatable winding roller 11 for winding the cable. The cable to be wound passes through the guide mechanism and is wound around the outside of the winding roller 11. Both ends of the winding roller 11 are rotatably mounted on a support frame 12, and one end of the winding roller 11 is connected to the output shaft of a driving motor 13. When the driving motor 13 is started, the winding roller 11 can be driven to rotate for winding operation. The rotatable mounting method of the winding roller 11 is a structure in the prior art and will not be described in detail here.

[0023] The guide mechanism includes a movable seat 3 that can reciprocate along the axial direction of the winding roller 11. The movable seat 3 is driven by a traction mechanism 2. The traction mechanism 2 includes a driving motor 21 and a transmission screw 23. The two ends of the transmission screw 23 are rotatably mounted on a mounting seat 22 through bearings, and the mounting seat 22 is fixedly arranged on a frame or the ground. One end of the transmission screw 23 is connected to the output shaft of the driving motor 21. The outer side of the transmission screw 23 is provided with a thread, and the movable seat 3 is threadedly sleeved on the outer side of the transmission screw 23. At the same time, in order to prevent the movable seat 3 from rotating circumferentially relative to the transmission screw 23, the present embodiment is also connected with a guide rod 8 between the two mounting seats 22. The axis of the guide rod 8 is parallel to the axis of the transmission screw 23, and the movable seat 3 is slidably sleeved on the outer side of the guide rod 8. When the driving motor 21 is started, the transmission screw 23 is driven to rotate, thereby driving the movable seat 3 to reciprocate linearly along the axial direction of the transmission screw 23.

[0024] The movable seat 3 is provided with two rotatable vertical rollers 4 arranged at intervals. The rotatable installation method of the vertical rollers 4 is a structure in the prior art and will not be described in detail here. The movable seat 3 is also provided with two spaced connecting plates 6, and two horizontal rollers 5 are arranged between the two connecting plates 6 and arranged in parallel with each other, and the axis of the horizontal rollers 5 is parallel to the axis of the winding roller 11. The gap between the two vertical rollers 4 and the gap between the two horizontal rollers 5 are used for the passage of cables.

[0025] The two ends of the horizontal roller 5 are connected to the connecting plate 6 through the elastic components 7. Specifically in this embodiment, the horizontal roller 5 includes a roller body 51 and a central shaft 52. The roller body 51 is rotatably mounted on the central shaft 52 through a bearing, and the two ends of the central shaft 52 are connected to the elastic components 7. There is rolling friction between the roller body 51 and the cable, and the friction force is small. Figure 4 As shown, the elastic component 7 includes a clamping component and an elastic member 71. The clamping component is clamped and fixed on the outside of the central shaft 52. The elastic member 71 is connected between the clamping component and the connecting plate 6, and the elastic member 71 is in the vertical direction. When the elastic member 71 is extended and retracted, the central shaft 52 and the roller body 51 are driven to move up and down through the clamping component. In this embodiment, the elastic member 71 is a spring.

[0026] The clamping assembly includes a clamping plate 1 72 and a clamping plate 2 73. One end of the clamping plate 1 72 is hinged to one end of the clamping plate 2 73. The hinge adopts a hinge structure in the prior art, which will not be described in detail here. The other end of the clamping plate 1 72 is connected to the other end of the clamping plate 2 73 by a fastening bolt 74. The clamping plate 1 72 and the clamping plate 2 73 are respectively provided with an arc groove that fits the outer surface of the central axis 52 to improve the clamping and fixing effect. In this embodiment, this structure is adopted. The clamping plate 1 72 and the clamping plate 2 73 are detachably connected. Only by unscrewing the fastening bolt 74, the clamping plate 1 72 and the clamping plate 2 73 can be unfolded, thereby facilitating the removal or installation of the horizontal roller 5. The connecting plate 6 is fixedly provided with a limit block 62 corresponding to the clamping assembly. The limit block 62 abuts against the clamping assembly and is used to limit the limit position of the clamping assembly in the vertical direction. When the clamping assembly abuts against the limit block 62, the distance between the two horizontal rollers 5 is the smallest. In addition, in order to balance the center of gravity of the clamping assembly, a counterweight block 75 is fixedly provided on the clamping plate 1 72 or the clamping plate 2 73 near the hinge end in this embodiment, so that the center of gravity of the entire elastic assembly 7 is still in the center, avoiding the elastic assembly 7 from tilting.

[0027] In this embodiment, in order to improve the structural stability, the elastic component 7 and the horizontal roller 5 are respectively arranged on both sides of the connecting plate 6, and a through groove 61 for the central axis 52 to pass through is vertically opened on the connecting plate 6, that is, the central axis 52 is connected and fixed to the clamping component after passing through the through groove 61.

[0028] When winding, the cable is first passed through the two vertical rollers 4 and the two horizontal rollers 5 in sequence, and is wound around the outside of the winding roller 11. Then the drive motor 1 13 and the drive motor 2 21 are started to drive the winding roller 11 and the transmission screw 23 to rotate respectively. The rotation of the winding roller 11 is to rewind the cable; the rotation of the transmission screw 23 drives the moving seat 3 to make a reciprocating linear motion along the axial direction of the transmission screw 23, thereby driving the cable to be evenly wound along the axial direction of the winding roller 11. At the same time, during the winding and reeling process, the straight-line distance between the cable wound on the outside of the reeling roller 11 and the central axis of the reeling roller 11 will gradually increase, thereby driving the height of the cable passing through the horizontal roller 5 to gradually increase. During the change of the cable height, the force applied to the two horizontal rollers 5 will also change. When the cable height is low, the force applied to the lower horizontal roller 5 will also increase, thereby driving the lower horizontal roller 5 to overcome the elastic force of the elastic component 7 connected to it and move downward a certain distance, thereby reducing the friction between the cable and the horizontal roller 5; similarly, when the cable height is high, the force applied to the upper horizontal roller 5 will also increase, thereby driving the lower horizontal roller 5 to overcome the elastic force of the elastic component 7 connected to it and move upward a certain distance, thereby reducing the friction between the cable and the horizontal roller 5, which is more conducive to the smooth passage of the cable, reduces the wear on the cable surface and the surface of the horizontal roller 5, thereby extending the service life of the horizontal roller 5.

[0029] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
