Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable manufacturing, in particular to an anti-lock wire-releasing mechanism. Background Art

[0002] With the continuous progress of current social science and technology, the demand for cable products in the power, communication, transportation and other industries is increasing, and the traditional cable production method can no longer meet the demand for large-scale, high-quality and diversified cable products. Therefore, the wire stranding machine has become an indispensable part of cable production. The wire stranding machine is a kind of mechanical equipment that can be widely used in various soft / hard wires to twist multiple single wires into one strand to meet the process requirements of the wire.

[0003] Some twisting machines place the wires inside the equipment and achieve the twisting effect by internal pay-off. The wires are wound on reels and paid out by pulling. However, since the winding tension of each reel is different, the tension of each wire during pay-off is also inconsistent. During the twisting process of the cable, improper tension control or unstable tension may cause the cable to get stuck during pay-off and break.

[0004] Therefore, it is necessary to provide an anti-lock brake wire release mechanism to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide an anti-lock wire-releasing mechanism to ensure the stability of the tension during the cable release process, improve the efficiency of the cable release, and reduce production cost losses.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: an anti-locking wire-releasing mechanism, including a support frame for winding and releasing wires; a detachable wire-releasing shaft is horizontally arranged on the support frame, a wire gear is vertically sleeved on one end of the wire-releasing shaft, and a position-adjustable tensioner is arranged on the same side of the support frame as the wire gear, and the tension gear on the tensioner is meshed with the wire gear. The wire-releasing shaft is sleeved on the cable reel and supports the cable reel. When the cable reel is releasing wires, as one end of the cable is pulled, the entire cable reel will also rotate around it under the support of the wire-releasing shaft to realize automatic wire-releasing; when one end of the cable is pulled to rotate the wire-releasing shaft, the wire gear sleeved thereon will also rotate accordingly; the rotation speed of the tension gear on the tensioner is pre-adjusted according to the overall weight of the cable reel that needs to release the wire, and the wire gear is meshed with the tension gear, so that during the process of cable releasing, the cable is always in a stable tension state, and the cable locking phenomenon will not occur.

[0007] Furthermore, the support frame is arranged in an isosceles trapezoidal shape, and one of the two symmetrical sides is a wire-releasing side, and the other side is a wire-retrieving side, and the wire-releasing shaft is located on the wire-releasing side. The cable-releasing and wire-retrieving on the support frame are arranged on different sides to avoid interference caused by the cable-releasing during wire-retrieving. The wire-releasing shaft is used to pass through the cable reel to be laid. The wire-releasing side of the support frame is an inclined surface, which, on the one hand, facilitates the movement of the cable from the wire-releasing side to the wire-retrieving side under the action of tension, and on the other hand, can reduce the space occupied by the support frame and facilitate the loading of the cable reel.

[0008] Furthermore, both sides of the pay-off shaft are movably connected to the support frame through a lifting assembly, respectively. The lifting assembly includes a driving member, a rotating screw and a support seat. The rotating screw passes through the support seat and is threadedly connected thereto. The support seat is slidably connected to a guide rail arranged along the side of the support frame through a lifting slider. One end of the rotating screw is connected to a screw fixing seat on the support frame through a connecting bearing. A travel switch is arranged on the support frame. The driving end of the driving member is connected to one end of the rotating screw. When the driving member drives the rotating screw to rotate, the support seat threadedly connected to the rotating screw can drive the pay-off shaft placed thereon to move back and forth along the guide rail.

[0009] Cable reels of different sizes have different weights. It is not convenient to lift heavier cable reels manually for loading. In order to facilitate the loading of the cable reel with the cable wound on it onto the pay-off reel, it is necessary to provide a lifting assembly that can drive the pay-off reel to move in the pay-off direction. When the cable reel is heavier, the driving member drives the rotating screw rod to rotate so that the pay-off shaft moves toward the bottom of the supporting frame to facilitate the loading of the cable reel. After loading is completed, the driving member drives the rotating screw rod in the reverse direction to rotate so that the pay-off shaft moves in a direction away from the bottom of the supporting frame until the wire gear thereon engages with the tension gear on the tensioner. In order to ensure the accuracy of the meshing of the wire gear and the tension gear, a travel switch is provided on the supporting frame. When the support seat abuts against the travel switch, the driving member stops working.

[0010] Furthermore, the support seat comprises a support portion and a connection portion which are threadedly connected to the rotating screw, and the connection portion is provided with a placement groove for the wire-releasing shaft to rest on. The support portion on the support seat is used to connect the rotating screw, and the connection portion is used to support the wire-releasing shaft placed horizontally thereon.

[0011] Furthermore, a locking assembly is provided on the support seat, and the locking assembly includes an articulated seat provided on the support portion, a buckle locking member is hinged on the articulated seat, and one end of the buckle locking member away from the articulated seat is connected to the connecting portion through a locking screw. The locking assembly can limit the position of the line-releasing shaft, effectively preventing the line-releasing shaft from being separated from the support seat during the line-releasing rotation process, thereby preventing it from affecting the subsequent line-releasing efficiency.

[0012] Furthermore, a universal wheel is provided at each of the four corners of the bottom of the support frame. By providing the universal wheel, the wire-releasing mechanism is convenient to carry, so that the wire-releasing mechanism is suitable for wire-releasing equipment in different occasions, and the movement is more labor-saving, which effectively reduces the labor intensity of the staff.

[0013] Furthermore, it also includes an adjustment and positioning assembly, which includes a coil positioning frame and a locking bolt that are sleeved on the pay-off shaft and coaxially arranged therewith, the coil positioning frame is provided with an adjustment slot toward the center of the pay-off shaft, and the locking bolt passes through the adjustment slot and the disk surface on the cable reel and is locked and connected by a locking screw sleeve. By providing the adjustment and positioning assembly, it is effectively prevented that the cable reel is sleeved on the pay-off shaft and moves back and forth along the length direction of the pay-off shaft, thereby affecting the pay-off effect of the cable reel.

[0014] Furthermore, the tensioner is arranged on a connection seat, and the connection seat is connected to the support frame through a displacement adjustment component, and the displacement adjustment component includes an adjustment horizontal plate and an adjustment vertical plate arranged perpendicular to each other, and the adjustment horizontal plate and the adjustment vertical plate are provided with a plurality of waist-shaped holes, and the connection seat is provided with connection holes corresponding to the waist-shaped holes on the adjustment horizontal plate. The adjustment vertical plate is fixed on the support frame, and the adjustment horizontal plate is extended in a direction away from the support frame, and the side of the connection hole on the connection seat is parallel to the adjustment horizontal plate, and the waist-shaped holes on the adjustment horizontal plate are arranged along its length direction and connected to the connection holes by bolts, and the connection seat can be moved and locked on the adjustment horizontal plate along its length direction, thereby adjusting the distance between the tensioner and the support frame, and ensuring that there is no phenomenon of two gears colliding between the tension gear and the wire gear.

[0015] Beneficial effects of the utility model:

[0016] The utility model cooperates with each other through a support frame, a wire gear, a wire-releasing shaft, a tensioner and a tension gear. The wire gear meshes with the tension gear to ensure the stability of the tension during the cable pay-off process, improve the efficiency of the cable pay-off and reduce production cost losses.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] It should be noted that in the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] See attached Figures 1 to 5As shown, an anti-locking wire-releasing mechanism in this embodiment includes a support frame 1 for winding and releasing wires; a detachable wire-releasing shaft 9 is horizontally arranged on the support frame 1, and the wire-releasing shaft 9 is provided for the cable reel to be mounted and supports the cable reel. When the cable reel is releasing wires, as one end of the cable is pulled, the entire cable reel will also rotate around it under the support of the wire-releasing shaft 9, thereby realizing automatic wire-releasing; a wire gear 4 is vertically sleeved on one end of the wire-releasing shaft 9, and when one end of the cable is pulled to rotate the wire-releasing shaft 9, the wire gear 4 sleeved thereon also rotates accordingly; a position-adjustable tensioner 10 is arranged on the same side of the support frame 1 as the wire gear 4, and the tension gear 11 on the tensioner 10 is meshed with the wire gear 4, and the rotation speed of the tension gear 11 on the tensioner 10 is pre-adjusted according to the overall weight of the cable reel to be released, and the wire gear 4 is meshed with the tension gear 11, so that during the process of cable releasing, the cable is always in a stable tensioned state, and the cable locking phenomenon will not occur.

[0026] In some embodiments, the wire gear 4 has 170 teeth, an outer diameter of 430 mm, the tension gear 11 has 18 teeth, an outer diameter of 50 mm, and a thickness of 25 mm. Specifically, the tensioner 10 is a permanent magnet tension controller.

[0027] The support frame 1 is arranged in an isosceles trapezoidal shape, with one of the two symmetrical sides being the unwinding side and the other side being the winding side, and the unwinding shaft 9 is located on the unwinding side. The cable unwinding and winding on the support frame 1 are arranged on different sides to avoid interference caused by the cable unwinding during winding. The unwinding shaft 9 is used to pass through the cable reel to be unwinded. The unwinding side of the support frame 1 is an inclined surface, which, on the one hand, facilitates the movement of the cable from the unwinding side to the winding side under the action of tension, and on the other hand, can reduce the space occupied by the support frame 1 and facilitate the loading of the cable reel.

[0028] A plurality of rollers are horizontally arranged on the top of the support frame 1 along a direction perpendicular to the cable unwinding direction. The cable passes around the top of the support frame 1 when unwinding. The arrangement of the rollers not only supports the cable, but also prevents the surface of the cable from being damaged when it moves to the take-up side under tension, thereby ensuring the quality of the cable.

[0029] In some embodiments, it should be noted that the support frame 1 in the present application is not limited to an isosceles trapezoid, as long as one side can be used to place the cable reel for unwinding and the other side can facilitate the movement and rewinding of the cable. The support frame 1 plays the role of supporting the cable reel that needs to unwind.

[0030] The two sides of the pay-off shaft 9 are movably connected to the support frame 1 through a lifting assembly 6, respectively. The lifting assembly 6 includes a driving member 61, a rotating screw 62 and a support seat 5. The rotating screw 62 penetrates the support seat 5 and is threadedly connected thereto. The support seat 5 is slidably connected to a guide rail 64 arranged along the side of the support frame 1 through a lifting slider 63. One end of the rotating screw 62 is connected to a screw fixing seat 65 on the support frame 1 through a connecting bearing. A travel switch is arranged on the support frame 1. The driving end of the driving member 61 is connected to one end of the rotating screw 62. When the driving member 61 drives the rotating screw 62 to rotate, the support seat 5 threadedly connected to the rotating screw 62 can drive the pay-off shaft 9 placed thereon to move back and forth along the guide rail 64.

[0031] Cable reels of different sizes have different weights. It is not convenient to lift a heavier cable reel manually for loading. In order to facilitate the loading of the cable reel with the cable wound on it onto the pay-off reel, it is necessary to provide a lifting assembly 6 that can drive the pay-off reel to move along the pay-off direction. When the cable reel is heavier, the driving member 61 drives the rotating screw rod 62 to rotate, so that the pay-off shaft 9 moves toward the bottom of the supporting frame 1 to facilitate the loading of the cable reel. After the loading is completed, the driving member 61 drives the rotating screw rod 62 to rotate in the reverse direction, so that the pay-off shaft 9 moves in the direction away from the bottom of the supporting frame 1 until the wire gear 4 thereon is engaged with the tension gear 11 on the tensioner 10. In order to ensure the accuracy of the engagement of the wire gear 4 with the tension gear 11, a travel switch is provided on the supporting frame 1. When the support seat 5 abuts against the travel switch, the driving member 61 stops working.

[0032] In some embodiments, the driving member 61 is a driving motor, and the rotating shaft of the driving motor is connected to the rotating screw 62. It should be noted that it is not limited to the driving motor, and can also be other known mechanical structures that can drive the rotating screw 62 to rotate, such as a dividing plate.

[0033] In some embodiments, the rotating screw rod 62 is inclined along an inclined surface on the support frame 1 which is arranged in an isosceles trapezoid. When the wire-releasing shaft 9 drives the wire gear 4 thereon to move to engage with the tension gear 11, its moving path is along the above-mentioned inclined surface, thereby ensuring the direction of cable pay-off and the path of pay-off movement.

[0034] The support seat 5 includes a support portion 51 and a connection portion 52 which are threadedly connected to the rotating screw 62. The connection portion 52 is provided with a placement groove for the wire-releasing shaft 9 to rest on. The support portion 51 on the support seat 5 is used to connect the rotating screw 62, and the connection portion 52 is used to support the wire-releasing shaft 9 placed horizontally thereon.

[0035] In some embodiments, the placement groove is V-shaped, and the inclined edge of the inner wall of the V-shaped placement groove can effectively prevent the line-releasing shaft 9 from falling off the support seat 5 during movement and affecting subsequent line-releasing.

[0036] The support seat 5 is provided with a locking assembly 7, which includes an articulated seat 71 provided on the support portion 51, and a buckle locking member 72 is hingedly connected to the articulated seat 71, and one end of the buckle locking member 72 away from the articulated seat 71 is connected to the connecting portion 52 through a locking screw 73. The locking assembly 7 can limit the position of the line-releasing shaft 9, effectively preventing the line-releasing shaft 9 from being separated from the support seat 5 during the line-releasing rotation process, thereby preventing it from affecting the subsequent line-releasing efficiency.

[0037] In some embodiments, the snap-fit ​​locking member 72 is arranged in an arch shape, and its arched curved surface is adapted to the shape and size of the line-paying shaft 9. When the snap-fit ​​locking member 72 is snapped on the connecting portion 52 and screwed with the connecting portion 52, the line-paying shaft 9 is limited on the support seat 5, effectively preventing the line-paying shaft 9 from falling off the support seat 5 during the line-paying process, thereby avoiding affecting the subsequent line-paying effect.

[0038] The four corners of the bottom of the support frame 1 are all provided with a universal wheel 3. By providing the universal wheel 3, the wire-releasing mechanism is convenient to carry, so that the wire-releasing mechanism is suitable for wire-releasing of equipment in different occasions, and the movement is more labor-saving, which effectively reduces the labor intensity of the staff.

[0039] It also includes an adjustment and positioning assembly 8, which includes a coil positioning frame 81 and a locking bolt 83 that are sleeved on the pay-off shaft 9 and coaxially arranged therewith. The coil positioning frame 81 is provided with an adjustment slot 82 toward the center of the pay-off shaft 9, and the locking bolt 83 passes through the adjustment slot 82 and the disc surface on the cable reel and is locked and connected by a locking screw sleeve 84. By providing the adjustment and positioning assembly 8, it is effectively prevented that the cable reel is sleeved on the pay-off shaft 9 and moves back and forth along the length direction of the pay-off shaft 9, thereby affecting the pay-off effect of the cable reel.

[0040] In some embodiments, the coil positioning frame 81 is coaxially arranged with the pay-off shaft 9 through a bearing sleeve 85 .

[0041] The tensioner 10 is arranged on a connection seat 13, and the connection seat 13 is connected to the support frame 1 through a displacement adjustment assembly 12. The displacement adjustment assembly 12 includes an adjustment horizontal plate 121 and an adjustment vertical plate 122 arranged perpendicular to each other. The adjustment horizontal plate 121 and the adjustment vertical plate 122 are provided with a plurality of waist-shaped holes 123. The connection seat 13 is provided with a connection hole 14 corresponding to the waist-shaped hole 123 on the adjustment horizontal plate 121. The adjustment vertical plate 122 is fixed on the support frame 1, and the adjustment horizontal plate 121 is extended in a direction away from the support frame 1. The side of the connection seat 13 on which the connection hole 14 is provided is parallel to the adjustment horizontal plate 121. The waist-shaped hole 123 on the adjustment horizontal plate 121 is arranged along its length direction and connected to the connection hole 14 by bolts. The connection seat 13 can be moved and locked on the adjustment horizontal plate 121 along its length direction, thereby adjusting the distance between the tensioner 10 and the support frame 1, and ensuring that there is no phenomenon of two gears colliding between the tension gear 11 and the wire gear 4.

[0042] The support frame 1 is provided with a reinforcing plate 2 to ensure the support strength of the support frame 1 to the pay-off shaft 9 equipped with the cable reel.
