Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable production equipment, and particularly relates to an adjustable wire and cable conveying bracket. Background Technique

[0002] Wire and cable refers to materials used for power, electrical and related transmission purposes. There is no strict boundary between "wire" and "cable". Generally, products with fewer cores, smaller product diameters and simpler structures are called wires, those without insulation are called bare wires, and others are called cables; those with larger conductor cross-sectional areas (greater than 6 square millimeters) are called large cables, and those with smaller ones (less than or equal to 6 square millimeters) are called small wires or cloth wires. The wire and cable conveying bracket is mainly used to support, fix and convey wire and cable to ensure that the wire and cable remain stable during production and conveying, and prevent damage or deformation caused by external forces or its own weight.

[0003] Existing equipment generally conveys cables through several pairs of transmission rollers. When conveying multiple cables simultaneously, if some of the cables are stacked, it may cause the transmission rollers to exert excessive pressure on the cables during conveying, resulting in close contact and mutual extrusion between the cables, which in turn leads to an increase in the conductor resistance inside the cables. The increase in resistance will cause a voltage drop. At the same time, they may rub against each other during conveying, resulting in wear or damage to the cable outer skin, thereby affecting the electrical performance and safety of the cables.

[0004] In view of this, this application is specifically proposed. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-5 , the present invention provides a technical solution: including a bracket body 10, the longitudinal section of the bracket body 10 is in a "U" shape, one end of the two side walls of the bracket body 10 close to each other is rotatably connected with two first transmission rollers 11, and one end of the two side walls of the bracket body 10 far from the first transmission rollers 11 and close to each other is rotatably connected with two second transmission rollers 12. There are two adjusting rollers 30 between the first transmission rollers 11 and the second transmission rollers 12. The two adjusting rollers 30 are distributed vertically and are located in the same vertical plane. An adjusting ring 31 is installed on the outer arc wall of the adjusting roller 30. The adjacent two adjusting rings 31 on the same adjusting roller 30 are symmetrically arranged. The adjusting rings 31 at both ends of the adjusting roller 30 are in contact with the inner wall of the bracket body 10. The rotation angles between the adjusting rings 31 at the corresponding positions on the two adjusting rollers 30 differ by one hundred and eighty degrees;

[0030] The axis directions of the transmission roller 1 11, the transmission roller 2 12 and the adjusting roller 30 are parallel to the width direction of the bracket body 10. The two transmission rollers 11 and the two transmission rollers 2 12 are distributed along the vertical direction and are respectively located in the same vertical plane. The vertical line of the side wall of the two transmission rollers 11 close to each other is defined as L1, the vertical line of the side wall of the two transmission rollers 2 12 close to each other is defined as L2, and the vertical line of the side wall of the two adjusting rollers 30 close to each other is defined as L3. The midpoints of L1, L2 and L3 are all located in the same horizontal plane.

[0031] Two limit sliders 34 and two fixed sliders 32 are rotatably connected to the inner wall of the adjusting ring 31. The two fixed sliders 32 and the two limit sliders 34 are distributed in a ring array along the inner arc wall of the adjusting ring 31, and the limit sliders 34 and the fixed sliders 32 are staggered. A groove 1 is opened at one end of the inner wall of the adjusting ring 31 close to the fixed slider 32, and a fixed ear seat 33 is arranged in the groove 1. The fixed ear seat 33 is fixedly connected to the top of the fixed slider 32, and a mounting hole 1 is opened on the fixed slider 32 in the vertical direction;

[0032] The outer arc wall of the adjusting roller 30 is provided with a plurality of penetrating slide grooves 1 in the axial direction, the fixed slider 32 and the limit slider 34 are both adapted to the slide groove 1, and the inner wall of the slide groove 1 is provided with a plurality of equally spaced mounting holes 2 along its length direction, the mounting hole 1 and the mounting hole 2 have the same structure, and the same fixing bolt is installed in the mounting hole 1 and the mounting hole 2.

[0033] It should be noted that the adjusting ring 31 is tilted relative to the adjusting roller 30, that is, the axis of the adjusting ring 31 is not parallel to the adjusting roller 30. The adjusting ring 31 can be slid into the first slide groove on the adjusting roller 30 by using the fixed slider 32 and the limit slider 34, and then the adjusting ring 31 can be fixed on the adjusting roller 30 by using the fixed bolt installed in the aligned mounting hole 1 and mounting hole 2.

[0034] Since the adjusting ring 31 is tilted, it will swing back and forth along the axis of the adjusting ring 31 when the adjusting roller 30 rotates, thereby separating the stacked cables and also having a diversion effect. Further, multiple groups of adjusting rollers 30 and adjusting rings 31 can be set or multiple adjusting rings 31 can be installed on the adjusting roller 30 to move the stacked cables multiple times, and the spacing of the previous group of adjusting rollers 30 is larger than the spacing of the next group of adjusting rollers 30. The adjusting rings 31 on the two adjacent groups of adjusting rollers 30 are staggered, so that the cables can be separated in turn.

[0035] See also Figures 1-5, the present utility model provides a technical solution: on one side wall of the two second transmission rollers 12 close to the second driving gear set 21, the same driving mechanism is installed. The driving mechanism includes a first rotating shaft fixedly connected to one side wall of the second transmission roller 12 close to the first driving gear set 20. One end of the first rotating shaft away from the second transmission roller 12 penetrates through the bracket body 10. On one side wall of the first rotating shaft away from the second transmission roller 12, a second sprocket 47 is fixedly connected. The outer sides of the two second sprockets 47 are meshed with the same second chain 46. A tension pulley group 45 is arranged between the two second sprockets 47. The tension pulley group 45 is rotatably connected to the outer side wall of the bracket body 10. The second chain 46 is sleeved on the lower arc wall of the first rotating shaft located in the pulley groove of the tension pulley group 45. A third driving gear set 48 is arranged on the outer arc wall of the first rotating shaft located below. The third driving gear set 48 is fixedly connected to the second transmission roller 12 located below;

[0036] In the middle of one side wall of the tension pulley group 45 close to the bracket body 10, a second rotating shaft is fixedly connected. One end of the second rotating shaft away from the tension pulley group 45 is provided with a second bearing 43. One end of the first rotating shaft located above away from the second sprocket 47 is provided with a first bearing 42. At the position of the bracket body 10 corresponding to the first bearing 42, a vertical channel one penetrating along the width direction of the bracket body 10 is provided. At the position of the bracket body 10 corresponding to the second bearing 43, a horizontal channel two penetrating along the length direction of the bracket body 10 is provided. The first bearing 42 is slidably connected in the channel one. The second bearing 43 is slidably connected in the channel two;

[0037] On one side wall of the second bearing 43 close to the tension pulley group 45, two wedge-shaped blocks 44 are fixedly connected. The two wedge-shaped blocks 44 are rotationally symmetric about the axis of the second rotating shaft. On one side wall of the first bearing 42 close to the second sprocket 47, a limiting frame 41 is fixedly connected. The limiting frame 41 includes an L-shaped plate fixedly connected to one side wall of the first bearing 42 close to the second sprocket 47. The vertical part of the L-shaped plate is arranged downward. On the side wall of the vertical part of the L-shaped plate close to the second bearing 43, two guide rods distributed along the vertical direction are fixedly connected. The guide rods are arranged towards the wedge-shaped blocks 44 and are adapted to the wedge-shaped blocks 44. At the bottom of the vertical part of the L-shaped plate, a cylinder 40 is fixedly connected.

[0038] It should be noted that: both guide rods are inclined, and the two wedge-shaped blocks 44 are both located between the two guide rods. The wedge-shaped blocks 44 are in mutual contact with the guide rods. When the cylinder 40 drives the limiting frame 41 to move up and down, the guide rods move up and down synchronously, forcing the wedge-shaped blocks 44 to slide along the guide rods. However, under the action of the channel two, it can only move horizontally. Since the limiting frame 41 is fixedly connected to the first bearing 42, when the limiting frame 41 rises, it will drive the second transmission roller 12 and the second sprocket 47 located above to move. At the same time, the tension pulley group 45 moves horizontally adaptively to ensure that the second chain 46 is always in a taut state. When the cylinder 40 drives the limiting frame 41 to reset, the upper guide rod will drive the wedge-shaped blocks 44 to drive the second bearing 43 to slide in the reverse direction;

[0039] The drive gear set three 48 includes a drive gear three fixedly connected to the outer arc wall of the lower rotating shaft one. On one side wall of the lower transmission roller two 12 close to the drive gear set one 20, there is a drive gear three with the same structure fixedly connected. Both drive gears three are located outside the bracket body 10, and the two drive gears three are meshed and connected to each other. A motor one is fixedly connected to the outer side wall of the lower sprocket two 47. In this way, when the upper transmission roller two 12 moves in the vertical direction, the tightness of the chain two 46 remains unchanged and ensures that the rotation directions of the two transmission rollers two 12 are opposite;

[0040] The tensioning wheel set 45 includes a fixing plate fixedly connected to one end of the rotating shaft two away from the bearing two 43. The fixing plate is horizontally arranged. At both ends of the side wall of the fixing plate away from the rotating shaft two, a tensioning wheel one and a tensioning wheel two are respectively rotatably connected. The chain two 46 is respectively wound around the outer sides of the tensioning wheel one and the tensioning wheel two;

[0041] The channel one and the channel two do not contact, and the limit frame 41 and the tensioning wheel set 45 do not contact. When the bearing one 42 slides to the topmost end of the channel one, the bearing two 43 slides to one end of the channel two close to the transmission roller one 11, and at this time, the chain two 46 does not contact the tensioning wheel set 45.

[0042] Please refer to Figures 1-5 , the present utility model provides a technical solution: on one side wall of the two transmission rollers one 11, there is a same drive gear set one 20 installed. On one side wall of the two adjusting rollers 30 close to the drive gear set one 20, there is a same drive gear set two 21 installed. Both the drive gear set one 20 and the drive gear set two 21 are located outside the bracket body 10. On the side wall of the drive gear set one 20 and the drive gear set two 21 away from the bracket body 10, there is a sprocket one 22 fixedly connected. On the outer sides of the two sprockets one 22, there is a same chain one 23 meshed and connected.

[0043] It should be noted that: the drive gear set one 20 includes drive gears one respectively fixedly connected to the side walls of the two transmission rollers one 11, and the two drive gears one are meshed and connected to each other. The drive gear set two 21 includes drive gears two respectively fixedly connected to the side walls of the two adjusting rollers 30, and the two drive gears two are meshed and connected to each other. Among them, on the side walls of the lower drive gear one and the lower drive gear two away from the bracket body 10, there is a sprocket one 22 fixedly connected. On the outer side wall of one of the sprockets one 22, there is a motor two fixedly connected.

[0044] Working principle:

[0045] When multiple cables are sent from the first transmission roller 11, after being toggled by the adjusting roller 30 and the adjusting ring 31, the originally stacked cables are separated and transported along the adjusting ring 31 on the adjusting roller 30 respectively, and the driving mechanism can change the distance between the two second transmission rollers 12 while ensuring that the transmission does not stop or jam.
