Description

Technical Field

[0001] The present invention relates to the technical field of cable equipment, in particular to a wire and cable winding device. Background Art

[0002] Wires and cables are very common in daily life. They are used in everything from power transmission cables to household appliances and other electrical equipment. During the production, transportation, and use of wires and cables, they need to be reeled in. After being reeled in, the wires and cables have the advantages of small footprint and easy mobility and transportation. Most of the existing wire and cable reeling devices are of fixed size. Therefore, when reeling in, different cables need to select corresponding reeling wheels for reeling to avoid damage to the cable structure or loose cable roll structure after reeling due to unsuitable reeling wheels. However, this method requires the preparation of various types of reeling wheels, which increases costs. If the reeling wheel is unsuitable, the cable needs to be frequently replaced, which leads to low efficiency of cable reeling operations.

[0003] For example, the existing patent announcement number is: CN111517169A, which discloses a residual cable winding device, including a base, a motor, an active turntable, and an adjustable shaft. The center of the active turntable is fixedly connected to a central shaft, and the active turntable is provided with an adjustable shaft groove, and an adjustable shaft is slidably connected in the adjustable shaft groove, and an adjusting rod is provided on the adjustable shaft. In the technical solution of this comparative document, when winding the cable, it is necessary to manually adjust multiple adjusting rods in advance to adjust the diameter of the winding wheel composed of multiple adjustable shafts to adapt to cables of different lengths to achieve effective winding. Although this method does not require frequent replacement of the winding wheel, each adjustment work requires adjusting all the adjusting rods one by one, and when the number is large, it increases the workload of the staff, and manual adjustment of the winding wheel diameter is prone to estimation errors. If the estimation is wrong, the cable needs to be removed and readjusted.

[0004] In view of this, we propose a wire and cable winding device with an adjustable winding wheel size. Summary of the Invention

The round rod passes through the connecting block up and down so that the connecting block can move up and down along the round rod in the adjustment groove.

[0010] Preferably, the outer side of the connecting block extends to the outer side of the circular turntable and has protruding claws extending to both sides, and the inner side of the connecting block is fixedly connected to both ends of the movable shaft.

[0011] Preferably, the variable tension unit includes two upward vertical rods, the vertical rods are located on the left and right sides of the device bottom plate, and a horizontal rod and a rotating rod with threads are provided between the middle section and the top of the vertical rods. The rotating rod is provided with a tension adjustment ring that can move left and right along the rotating rod.

[0012] The tension adjustment ring includes a circular ring through which the cable can pass. One side of the circular ring wall is provided with an adjusting nut that passes through the ring wall. The adjusting nut is located on the inner end of the circular ring and is fixed with a clamping block for adjusting the cable tension. A stabilizing block is fixed below the tension adjustment ring. The upper and lower ends of the stabilizing block are provided with through holes that pass through to the left and right, and the rotating rod and the cross bar pass through the through holes.

[0013] Preferably, the side walls of the circular turntable on both sides of the adjustment slot are provided with symmetrical strip grooves, the length of the strip grooves is smaller than the length of the adjustment slot, and the strip grooves are located on both sides of the upper half of the adjustment slot.

[0014] Preferably, the adjustment groove runs through the left and right sides of the circular turntable, and the top of the adjustment groove is located below the edge of the circular turntable.

[0015] Preferably, the outer side of the circular turntable is provided with a plurality of semicircular notches arranged in an array around the circular turntable, and the notches are arranged horizontally and pass through the left and right sides of the circular turntable.

[0016] Preferably, a rectangular groove is formed on the top wall of the bottom plate, and a limiting rod assembly for preventing the winding mechanism from being dislocated is arranged in the rectangular groove.

[0019] Beneficial effects

[0020] Compared with the prior art, the present invention provides a wire and cable winding device with the following beneficial effects:

[0021] 1. The movable shaft is set to slide in the same direction on the two circular turntables, so that the diameter of the winding wheel composed of multiple movable shafts can be freely changed. The variable tension unit used in conjunction with it can change the cable stretching coefficient of the section between the two during the winding process. When the stretching coefficient increases, the tension between the movable shaft and the tension adjustment ring increases. At this time, the movable shaft receives a large tension from the wound cable to compress the reset spring. After a full circle of winding, the diameter of the winding wheel composed of the movable shaft becomes smaller. Conversely, when the stretching coefficient decreases, the tension received by the reset spring is very small, and the diameter of the winding wheel composed of the movable shaft combination will become larger, thereby realizing the winding work according to cables of different lengths.

[0022] Second, a return spring with an opposite force to the movable shaft is set in the adjustment slot. When the cable is wound onto the movable shaft, the return spring resets the movable shaft upward, so that the cable wound on the movable shaft can remain tightened and prevent the cable from loosening.

[0023] 3. The notch is located on the outside of the circular turntable and cooperates with the limiting rod assembly set on the bottom plate to limit the winding mechanism. A triangle is formed between the two opposite limiting rod assemblies and the notch, which improves stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Figure 1-7As one embodiment of the present invention, a wire and cable winding device includes a device base 1, two left-right symmetrical triangular brackets 2 are provided above the base 1, and a rotatable winding mechanism 3 is provided between the two triangular brackets 2; the winding mechanism 3 includes a central rotating shaft 31 connected to the triangular bracket 2, and both ends of the central rotating shaft 31 are located on the inner side of the triangular bracket 2 and are provided with circular turntables 32 that rotate coaxially with the central rotating shaft 31. The central rotating shaft 31 rotates synchronously with the circular turntable 32 to realize the cable winding work, and the circular turntable 32 is provided with adjustment slots 33 arranged in an array with the center of the circular turntable 32. The adjustment slots 33 between the two circular turntables 32 correspond to each other and a movable shaft 34 that can move along the adjustment slots 33 is provided between the two circular turntables 32. When winding, the cable is wound to the outside of the movable shaft 34, and an adjusting portion 35 for adjusting the height of the movable shaft 34 is provided in the adjusting groove 33. Fixed circular holes 341 are provided at both ends and in the middle of the movable shaft 34 for the cable ends to pass through. A variable tension unit 4 that can change the cable tension with the winding mechanism 3 is provided on the bottom plate 1 of the device. When the cable needs to be wound, one end of the cable is passed through the variable tension unit 4 and fixed on the circular hole 341 according to the expected number of cables. The variable tension unit 4 is adjusted to adjust the tension of the cable between the adjusting portion 35 and the variable tension unit 4, so that the adjusting portion 35 is adjusted downward to lower the height of the movable shaft 34, and the cable is wound onto the movable shaft 34. Since the tension of the cable is fixed, the pull-down heights of multiple movable shafts 34 are the same, which reduces the adjustment error.

[0039] The variable tension unit 4 includes two upward vertical poles, which are located on the left and right sides of the device base plate 1. A cross bar 41 and a rotating rod 42 with a thread are provided between the middle section and the top of the vertical poles. The rotating rod 42 is provided with a tension adjustment ring 43 that can move left and right along the rotating rod 42. The tension adjustment ring 43 includes a circular ring 431 for passing the cable. An adjusting nut 432 that passes through the circular ring 431 is provided on one side of the circular ring wall. A clamping block 433 for adjusting the cable tension is fixed at one end of the adjusting nut 432 located on the inner side of the circular ring 431. A stabilizing block 434 is fixed below the tension adjustment ring 43. In actual work, the cable to be wound is passed through the circular ring 431, the cable end is fixed on the movable shaft 34, and the adjusting nut 432 is manually adjusted so that the clamping block 433 clamps the cable. When the central shaft 31 rotates, the clamping block 433 clamps the cable and generates friction, causing the cable to pull the movable shaft 34 toward the movable shaft 34, thereby achieving the purpose of adjusting the diameter of the movable shaft 34. The upper and lower ends of the stabilizing block 434 are provided with through holes passing through left and right, and the rotating rod 42 and the cross bar 41 pass through the through holes. The rotating rod 42 and the cross bar 41 are both fixedly arranged, which can maintain the stability of the stabilizing block 434 and prevent the ring 431 from being damaged due to excessive tension during work. At the same time, the inner wall of the through hole in the upper section of the stabilizing block 434 is provided with a thread that cooperates with the rotating rod 42. The tension adjusting ring 43 is rotated by the forward and reverse rotating motor arranged at one end of the rotating rod 42, so that the tension adjusting ring 43 moves left and right on the rotating rod 42, and at the same time can adjust the position of the cable when it is wound, so as to keep the cables on the winding wheel arranged neatly.

[0040] The adjusting portion 35 includes a round rod 351 fixed to the top and bottom walls of the adjusting groove 33, a return spring 352 is provided on the outside of the round rod 351, and a connecting block 353 is fixedly connected to the top of the return spring 352. The round rod 351 passes through the connecting block 353 up and down so that the connecting block 353 can move up and down along the round rod 351 in the adjusting groove 33. After the cable is wound, the return spring 352 generates upward pressure on the movable shaft 34, so that the cable wound on the movable shaft 34 can remain in a tightened state to prevent the cable from loosening. At the same time, when the winding work is in progress, the round rod 351 limits the moving range of the connecting block 353 to only within the adjusting groove 33, effectively preventing the movable shaft 34 from deviating and shifting.

[0041] The outer side of the connecting block 353 extends to the outer side of the circular turntable 32 and has protruding claws 354 extending on both sides. The inner side of the connecting block 353 is fixedly connected to the two ends of the movable shaft 34. The side walls of the circular turntable 32 on both sides of the adjusting slot 33 are provided with symmetrical strip grooves 36. The protruding claws 354 penetrate into the strip grooves 36 to slide up and down, further stabilizing the moving path of the connecting block 353 and preventing the connecting block 353 from shifting. The length of the strip groove 36 is less than the length of the adjusting slot 33, and the strip groove 36 is located on both sides of the upper half of the adjusting slot 33, so that the connecting block 353 can move within the upper half of the adjusting slot 33, leaving the space in the lower half of the adjusting slot 33 for the reset spring 352 to prevent the reset spring 352 from being damaged due to excessive pressure.

[0042] The adjusting groove 33 passes through the left and right sides of the circular turntable 32, and the top of the adjusting groove 33 is located below the edge of the circular turntable 32, ensuring that when there are fewer cables, they can be wound onto the device to prevent the cables from loosening.

[0043] The outer side of the circular turntable 32 is provided with a plurality of semicircular notches 37 arranged in an array around the circular turntable 32. The notches 37 are used to maintain the stability of the winding mechanism 3 after winding and prevent the cable from loosening during transportation or movement. The notches 37 are arranged horizontally and run through the left and right sides of the circular turntable 32.

[0044] A rectangular groove 11 is provided on the top wall of the bottom plate 1, and a limiting rod assembly 12 is provided in the rectangular groove 11 to prevent the winding mechanism 3 from being dislocated. The limiting rod assembly 12 includes two groups of symmetrically arranged support rods 121, and the support rod 121 includes a bottom rod 1211 rotatably connected to the two side walls of the rectangular groove 11, and a plurality of vertical vertical rods 1212 are provided on the bottom rod 1211. The ends of the vertical rods 1212 are fixedly connected with horizontally arranged insertion rods 1213. The insertion rods 1213 are connected to the bottom rod 1211 through the connection of the vertical rods 1212 so that the insertion rods 1213 are connected in the vertical direction with the bottom rod 1211 as the center. After the winding work is completed or when the winding mechanism 3 needs to be limited, the circular turntable 32 is stuck by adjusting the limiting rod assembly 12. Figure 6 As shown, the vertical rod 1212 and the insertion rod 1213 are pulled upward along the bottom rod 1211, and the insertion rod 1213 is inserted into the notch 37, so that a triangle is formed between the two opposite limiting rod assemblies 12 and the notch 37 to improve stability.

[0045] The length of the vertical rod 1212 is greater than the distance from the notch 37 to the base plate 1, and the diameter of the insertion rod 1213 is adapted to the diameter of the notch 37, ensuring that after the insertion rod 1213 is inserted into the notch 37, there is an angle between the vertical rod 1212 and the base plate 1, which can clamp the notch 37 and thus press against the circular turntable 32 to keep it stable and no longer rotate.

[0046] One end of the central rotating shaft 31 extends to the outside of the triangular bracket 2 and is connected to a rotating motor, which drives the central rotating shaft 31 and the circular turntable 32 to rotate to realize the winding and unwinding of the cable.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
