Description
Technical Field
[0001] The utility model relates to the technical field of cable stranding machines, in particular to a cable stranding machine with a multi-stage stranding structure. Background Art
[0002] A cable stranding machine is a mechanical device that can be widely used in the stranding of various soft / hard conductor wires (such as copper wires, enameled wires, tinned wires, copper-clad steel, copper-clad aluminum, etc.) and electronic wires (such as power cords, headphone wires, telephone wires, PVC wires, network wires, etc.). It can twist multiple single-conductor wires into one strand to meet the process requirements of the wire.
[0003] The working principle of the existing cable stranding machine is mainly based on rotational and winding mechanical actions. Generally, a cable stranding machine consists of a wire feeding device, a stranding device, a traction device, a take-up device, etc. During operation, multiple single wires are fed out from the wire feeding device and enter the stranding device through guide wheels. The stranding device generally consists of one or more rotating reels or cages. When the reel or cage rotates, it drives these single wires to rotate and wind around a central axis, thus realizing the stranding process. During the stranding process, by controlling parameters such as the rotation speed, rotation direction, and pitch of the reel or cage, stranded wires with different specifications and performance requirements can be obtained. The traction device is responsible for traction the stranded cable at an appropriate speed to make it move forward smoothly. Finally, the take-up device winds up the completed cable in an orderly manner.
[0004] However, by using the above method, during the stranding process of the existing cable stranding machine, since the cable is mostly paid out by the rotation of the wire feeding wheel, the wire feeding wheel is very likely to pay out too much cable under the action of inertia, resulting in the cable being relatively loose during the stranding process, thereby affecting the final stranding quality. Content of the Utility Model
[0005] The purpose of the utility model is to provide a cable stranding machine with a multi-stage stranding structure, which can avoid the problem of cable slack caused by inertia during cable payout through the provided components, so that the cable is always in a taut state during cable payout, thereby ensuring the final stranding quality.
[0006] To achieve the above purpose, the utility model provides a cable stranding machine with a multi-stage stranding structure, including a frame, a stranding machine body, and a fixed bracket. The stranding machine body is installed on one side of the frame, and the fixed bracket is fixedly installed on one side of the frame. It further includes a wire feeding assembly;
[0007] The line-releasing assembly includes a connecting bracket, a rotating shaft, a toggle rod, a reset member and a resisting member; the connecting bracket is fixedly connected to the fixed bracket and is located on one side of the fixed bracket, the rotating shaft is rotatably connected to the connecting bracket and is located on one side of the connecting bracket, the toggle rod is fixedly connected to the rotating shaft and is located on one side of the rotating shaft, the reset member is connected to the connecting bracket, and the resisting member is connected to the rotating shaft.
[0008] Wherein, the reset component includes a rotating disk, a driving torsion spring, a connecting platform and a clamping component, the rotating disk is rotatably connected to the connecting bracket and is located on one side of the connecting bracket; the two sides of the driving torsion spring are respectively connected to the rotating disk and the connecting bracket; the connecting platform is fixedly connected to the rotating disk and is located on one side of the rotating disk; the clamping component is connected to the connecting platform.
[0009] Among them, the holding component includes a disbursement platform, a rotating baffle, a reset torsion spring and a limiting bottom ring, the disbursement platform is fixedly connected to the connecting platform and is located on one side of the connecting platform; the rotating baffle is rotatably connected to the disbursement platform and is located on one side of the disbursement platform; the two sides of the reset torsion spring are respectively connected to the rotating baffle and the disbursement platform; the limiting bottom ring is fixedly connected to the fixed bracket and is located on a side of the fixed bracket close to the rotating baffle.
[0010] Wherein, the rotating shaft has a rotating boss and a matching groove, wherein the rotating boss is located on a side of the rotating shaft close to the connecting bracket; and the matching groove is located on one side of the rotating shaft.
[0011] Wherein, the resisting member includes a threaded rod and a screwing nut, the threaded rod is fixedly connected to the rotating shaft and is located on one side of the rotating shaft; the screwing nut is threadedly connected to the threaded rod and is sleeved on the threaded rod.
[0012] A cable strander with a multi-stage stranded wire structure according to the present utility model is fitted and installed with a pay-off wheel through a fitting groove provided on a rotating shaft, so that the rotating shaft and the pay-off wheel rotate in unison. When the rotating shaft rotates following the pay-off wheel, the rotating shaft drives a toggle rod to rotate. Then, the toggle rod cooperates with the end of a rotating baffle. Since the bottom surface of the rotating baffle cooperates with a limiting bottom ring, the rotating baffle cannot rotate normally and can only drive a rotating disc to rotate under the drive of the toggle rod. When the rotating baffle is driven by the toggle rod to a break groove provided on the limiting bottom ring, since the rotating baffle can rotate, the rotating baffle rotates under the action of the toggle rod. When the toggle rod continues to rotate to the rear of the rotating baffle following the rotating shaft, the rotating baffle is reset under the action of a reset torsion spring. When being reset through a reset spring, the rotating baffle can be limited by a limiting platform provided on a protruding platform. Since the rotating disc is no longer stressed after the rotating baffle is reset, the rotating disc rotates and resets under the action of a driving torsion spring. At this time, the rotating shaft still continues to rotate and pay off the cable following the pay-off wheel. When the rotating shaft rotates over, the toggle rod cooperates with the rotating baffle again, and the above steps are continuously performed. Thus, when the pay-off wheel has an inertial rotation, the rotating disc that is reset can cooperate with the driving torsion spring and the rotating baffle to apply a force in the opposite rotation direction to the toggle rod and the rotating shaft, so that the cable paid off by the pay-off wheel can always be kept in a taut state, realizing the problem that the cable can be prevented from being slack due to the inertial effect during cable pay-off by the provided components, ensuring that the cable is always in a taut state during cable pay-off, and further guaranteeing the final stranding quality.

Figure 2 yes Figure 2 A magnified image of Figure 3 is a schematic diagram of the structure of the reset component. Figure 4 It is a schematic diagram of the structure of the connection bracket 104 in section.
[0023] The utility model provides a cable stranding machine with a multi-stage stranding structure: comprising a frame 101, a stranding machine body 102, a fixed bracket 103 and a pay-off assembly, the pay-off assembly comprising a connecting bracket 104, a rotating shaft 105, a toggle rod 106, a reset component and a resisting component, the reset component comprising a rotating disk 107, a driving torsion spring 108, a connecting platform 109 and a clamping component, the clamping component comprising a dispensing platform 110, a rotating baffle 111, a reset torsion spring 112 and a limiting bottom ring 113, the rotating shaft 105 having a rotating boss 114 and a matching groove 115, the above-mentioned scheme solves the problem that in the process of stranding of the existing cable stranding machine, since the cable is mostly paid out by the rotation of the pay-off wheel, the pay-off wheel is very likely to pay out too much cable under the action of inertia, thereby making the cable relatively loose during the stranding process, thereby affecting the final stranding quality.
[0024] In this embodiment, the stranding machine body 102 is installed on one side of the frame 101, and the fixed bracket 103 is fixedly installed on one side of the frame 101. The stranding machine body 102 is an existing multi-stage stranding machine. The stranding machine body 102 is fixedly set on a bracket boss provided on the frame 101, and the fixed bracket 103 is fixedly set on the frame 101. The fixed bracket 103 is provided to facilitate the installation of subsequent components.
[0025] The connecting bracket 104 is fixedly connected to the fixed bracket 103 and is located on one side of the fixed bracket 103; the rotating shaft 105 is rotatably connected to the connecting bracket 104 and is located on one side of the connecting bracket 104; the toggle rod 106 is fixedly connected to the rotating shaft 105 and is located on one side of the rotating shaft 105; the reset member is connected to the connecting bracket 104; the resisting member is connected to the rotating shaft 105; the rotating boss 114 is located on one side of the rotating shaft 105 close to the connecting bracket 104; the matching groove 115 is located on one side of the rotating shaft 105; the connecting bracket 104 is provided with a plurality of connecting bosses, each of which is rotatably mounted with the rotating shaft 105; the rotating shaft 105 is connected to the connecting bracket 104 ... The rotating boss 114 provided on the inner side matches the rotating groove on the connecting boss of the connecting bracket 104, so that the rotating shaft 105 can rotate normally. The rotating shaft 105 is also provided with a plurality of matching grooves 115. The matching grooves 115 provided on the rotating shaft 105 are adapted to the matching bosses provided in the corresponding matching holes of the pay-off wheel, so that the rotating shaft 105 and the provided pay-off wheel can maintain consistent rotation through the matching of the grooves. The toggle rod 106 is fixed to the end of the rotating shaft 105. The toggle rod 106 cooperates with the reset member to limit the inertial rotation of the rotating shaft 105 and the pay-off wheel accordingly, thereby ensuring that the pay-off wheel will not cause the cable to become loose due to inertial rotation when the cable is paid out.
[0026] Secondly, the rotating disk 107 is rotatably connected to the connecting bracket 104 and is located on one side of the connecting bracket 104; both sides of the driving torsion spring 108 are connected to the rotating disk 107 and the connecting bracket 104 respectively; the connecting platform 109 is fixedly connected to the rotating disk 107 and is located on one side of the rotating disk 107; the clamping member is connected to the connecting platform 109, the dispensing platform 110 is fixedly connected to the connecting platform 109 and is located on one side of the connecting platform 109; the rotating baffle 111 is rotatably connected to the dispensing platform 110 and is located on one side of the dispensing platform 110; both sides of the return torsion spring 112 are connected to the rotating baffle 111 and the dispensing platform 110 respectively; the limiting bottom ring 113 is fixedly connected to the fixed bracket 103 and is located on one side of the fixed bracket 103 close to the rotating baffle 111. The rotating disk 107 is rotatably sleeved on the connecting boss of the connecting bracket 104. There is a driving torsion spring 108 between the rotating disk 107 and the side-round platform of the connecting bracket 104. The connecting platform 109 is fixed to the outside of the rotating disk 107. The dispensing platform 110 is fixedly installed on the connecting platform 109. The rotating baffle 111 is rotatably installed on the dispensing platform 110. A return torsion spring 112 is installed between the rotating baffle 111 and the dispensing platform 110. At the same time, a corresponding limiting platform is also provided on the dispensing platform 110. A limiting block for cooperating with the connecting platform 109 is also provided on the limiting bottom ring 113 provided at the rear of the rotating baffle 111. Under normal non-loaded conditions, the rotating disk 107 will make the back side of the connecting platform 109 abut against the limiting block on the limiting bottom ring 113 under the action of the driving torsion spring 108, so as to correspondingly reset the rotating disk 107 and the rotating baffle 111 through the driving torsion spring 108 and the return torsion spring 112, and then cooperate with the limiting bottom ring 113 and the toggle lever 106 to complete the restriction of the inertial rotation of the wire reel and the rotating shaft 105.
[0027] When a cable stranding machine with a multi-stage stranding structure of the present embodiment is used, the mating groove 115 provided on the rotating shaft 105 is used to cooperate with the pay-off wheel for installation, so that the rotating shaft 105 and the pay-off wheel rotate in unison. When the rotating shaft 105 rotates following the pay-off wheel, the rotating shaft 105 drives the toggle rod 106 to rotate, and then the toggle rod 106 cooperates with the end of the rotating baffle 111. Since the bottom surface of the rotating baffle 111 cooperates with the limiting bottom ring 113, The rotating baffle 111 cannot rotate normally, and can only drive the rotating disk 107 to rotate under the drive of the toggle rod 106. When the rotating baffle 111 is driven to the broken groove provided on the limiting bottom ring 113 by the toggle rod 106, the rotating baffle 111 can rotate, so the rotating baffle 111 will rotate under the action of the toggle rod 106. When the toggle rod 106 continues to rotate to the rear side of the rotating baffle 111 following the rotating shaft 105, the rotating baffle 111 will rotate. The reset is completed under the action of the reset torsion spring 112. When the reset is performed by the reset spring, the rotating baffle 111 can be limited by the limit platform provided on the expenditure platform 110. Since the rotating disk 107 is no longer subjected to force after the rotating baffle 111 is reset, the rotating disk 107 will rotate and reset under the action of the driving torsion spring 108. At this time, the rotating shaft 105 continues to rotate with the pay-off wheel to pay the cable. When the rotating shaft 105 rotates over, the toggle rod 106 will engage with the rotating baffle 111 again The above steps are continued, so that when the pay-off wheel rotates by inertia, the resetting rotating disk 107 can cooperate with the driving torsion spring 108 and the rotating baffle 111 to apply an opposite rotation force to the toggle rod 106 and the rotating shaft 105, so that the cable paid out by the pay-off wheel can be kept taut at all times, and the problem of cable slack caused by inertia of the pay-off wheel when paying out the cable can be avoided through the provided components, so that the cable is always in a taut state when paying out the cable, thereby ensuring the final quality of the stranded wire.

[0030] Wherein, the threaded rod 201 is fixedly connected to the rotating shaft 105 and is located on one side of the rotating shaft 105; the screwing nut 202 is threadedly connected to the threaded rod 201 and sleeved on the threaded rod 201. The threaded rod 201 is fixedly arranged at the end of the rotating shaft 105. The screwing nut 202 is provided with a threaded through hole adapted to the threaded rod 201. By means of the cooperation of the provided threaded rod 201 and the screwing nut 202, the outer side of the wire pay-off wheel can be conveniently limited. Multiple bosses are arranged at the outer end of the screwing nut 202, so that the user can directly install and disassemble the screwing nut 202 by hand-tightening.
[0031] When using a cable strander with a multi-stage stranding structure according to this embodiment, the user can conveniently install and disassemble the wire pay-off wheel by means of the cooperation of the provided threaded rod 201 and the screwing nut 202, which greatly enhances the practicability of the entire device.
