Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable processing, in particular to a tractor for wire and cable production. Background Art

[0002] In order to improve the performance of cables during the production process, wires and cables are often subjected to corresponding annealing treatment. After the annealing is completed, it is often necessary to use a tractor to pull out the annealed cable before the material can be collected smoothly.

[0003] For example, the Chinese patent CN206003556U of the prior art discloses an automatic annealing traction mechanism for electric wires and cables, comprising an annealing mechanism, a water tank, a traction mechanism, and a wire-taking mechanism arranged in sequence, wherein the annealing mechanism comprises a first preheating wheel, a second preheating wheel, and an annealing wheel, at least one guide roller for increasing the range is arranged between the first preheating wheel and the second preheating wheel, and the conductor between the second preheating wheel and the annealing wheel is arranged in a steam pipe; the traction mechanism comprises a pair of crawlers symmetrical in upper and lower directions, and the back of the contact surfaces of the pair of crawlers are provided with a plurality of clamping devices that clamp against each other, and the clamping devices are provided with a plurality of pressure rollers in parallel to press the back of the crawlers, and the plurality of clamping devices are arranged under the same crossbeam, and the pressure of the crossbeam is controlled by a pressure control mechanism.

[0004] However, the above-mentioned existing traction mechanism has certain defects during use. The cable is pressed by the pressure roller to generate friction with the upper and lower belts to achieve cable traction. However, when the speed of the belt transmission structure changes, this is likely to cause internal cable accumulation, resulting in cable bending problems, resulting in subsequent cable traction is not smooth, affecting work efficiency. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a tractor for wire and cable production to solve the shortcomings existing in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following contents:

DETAILED DESCRIPTION

[0023] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model proposes a traction device for wire and cable production, including a horizontally arranged fixed base 1, a mounting side frame 2 is arranged in the middle of the surface of the fixed base 1, and guide roller assemblies 3 are symmetrically arranged on the surface of the fixed base 1 and are respectively located on both sides of the mounting side frame 2. The wires and cables flow to and pass through the mounting side frame position through the guide roller assembly on one side, and then flow out from the position of the guide roller assembly on the other side. The guide roller assemblies on both sides ensure the consistency of the flow direction of the wires and cables without deviation.

[0025] Among them, two groups of four symmetrical traction wheels 4 are rotatably arranged on the side of the mounting side frame 2 through the rotating shaft 21, that is, the traction wheels 4 are arranged in pairs up and down, and the other end of the rotating shaft 21 is fixed to the mounting side frame 2 through the bracket 22. The middle of the circumferential surface of each traction wheel 4 is recessed to accommodate a traction groove 41 for accommodating cables. The upper and lower traction wheels 4 do not contact each other, and the traction grooves 41 of the upper and lower traction wheels 4 constitute an area for transmitting cables.

[0026] Among them, each rotating shaft 21 is provided with a driven gear 23, and the upper and lower driven gears 23 are meshed and connected. A driving gear 24 is provided in the middle of the two driven gears 23 at the bottom and is meshed and connected with the driving gear 24. The outer side surface of the mounting side frame 2 is provided with a motor 25 for driving the driving gear 24 to rotate; in this way, the rotation of the driving gear is realized by the drive of the motor, so that the two driven gears at the bottom drive the rotating shaft to rotate, thereby realizing the rotation of the traction wheel on the rotating shaft, and finally the rotating traction wheel conveys the cable in the traction groove in the conveying direction.

[0027] Among them, hollow first wire tubes 27 are horizontally arranged on both sides of the surface of the mounting side frame 2 through the tube seat 26, and the two first wire tubes 27 are both located on the center line between the upper and lower traction grooves 41; in this way, the cable sent out from the front guide roller assembly passes through the first wire tube on the front side and flows into the traction groove, then flows to the first wire tube on the rear side and finally flows out from the guide roller assembly on the rear side, and the first wire tube is used to ensure that the cables will not be piled up and dragged.

[0028] The traction device provided in this embodiment realizes the simultaneous rotation of four traction wheels by designing a motor, a driving gear, and a driven gear, thereby providing traction for the transfer of cables; by designing a traction groove and a first wire tube, the problem of cable accumulation and dragging when the rotation speed of the motor-driven driving gear changes can be effectively avoided, thereby effectively avoiding the phenomenon of cable bending due to accumulation in the middle of the traction process, and ultimately ensuring the working efficiency of wire and cable traction.

[0029] In this embodiment, a second hollow wire tube 28 is horizontally arranged in the middle of the surface of the mounting side frame 2 through a tube seat 26. The length of the second wire tube 28 is less than that of the first wire tube 27, and the second wire tube 28 is on the same horizontal line as the first wire tube 27. By adding the second wire tube to cooperate with the first wire tube, the phenomenon of the cable falling when passing through the middle position of the traction wheel during the cable traction process is avoided, thereby ensuring the smoothness of the cable traction.

[0030] In this embodiment, the guide roller assembly 3 includes a support frame 31 with front and rear openings, a guide wheel 32 is rotatably provided at the lower part of the support frame 31, a roller 33 is rotatably provided at the upper part of the support frame 31, a guide groove 321 for accommodating the cable is recessed in the middle of the circumferential surface of one side of the guide wheel 32, and the vertical center line of the guide groove 321 is consistent with the vertical center line of the traction groove 41. Through the action of the traction groove and the roller, the cable will not be offset during movement, and the cable can be moved and positioned to a certain extent.

[0031] The roller 33 has a pressing portion 331 protruding outward from the middle of its circumferential surface, and the pressing portion 331 corresponds to and cooperates with the guide groove 321. The pressing portion can act downward on the top of the cable in the guide groove, and the cable can pass through the guide groove smoothly without shaking.

[0032] A vertical slide groove 311 is provided on the upper part of the side wall of the support frame 31, a movable shaft 34 that can move up and down is placed between the two slide grooves 311, the roller 33 is rotatably arranged on the movable shaft 34, a vertical upward mounting shaft 35 is arranged in the middle of the movable shaft 34, a telescopic spring 351 is sleeved on the mounting shaft 35, and the upper end of the mounting shaft 35 can be movably inserted through the top plate of the support frame 31. In this way, the spacing between the pressing part and the guide groove can be controlled to meet the working requirements of cables of different diameters.

[0033] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here.
