Description

Technical Field

[0001] The utility model relates to the field of wire twisting machines, in particular to a copper wire twisting machine. Background Art

[0002] A wire twisting machine is a mechanical device that can be widely used for twisting various types of soft / hard conductor wires, so that multiple single conductors are twisted into one strand to meet the process requirements of the wire. According to the twisting method, wire twisting machines can generally be divided into single twisting machines, pair twisting machines, high-speed twisting machines, back-twisting machines, cage twisting machines, frame twisting machines, tubular twisting machines and disc twisting machines. In the prior art, copper wires often need to be combined into one strand through a wire twisting machine during production and processing. However, after the existing wire twisting machines have completed winding the copper wire through the twisting drum, the twisting drum is fixed for winding during use, which makes it inconvenient to install and disassemble the twisting drum when it is replaced later, thereby reducing work efficiency. For this purpose, the application number: CN202320383843.9 discloses a copper wire twisting machine, which belongs to the field of wire twisting machines and includes a machine base, and the front end of the top face of the machine base is fixedly connected to a lead drum. The top surface of the machine base is located behind the lead-in reel and is fixedly connected with a closing reel. A wire twisting mechanism is set. When the wire twisting reel has completed winding the copper wire passing through the lead-in hole and the closing reel hole, and the wire twisting reel needs to be replaced, the hand wheel is manually rotated to drive the double-headed screw to rotate through the first rotating rod, so that the symmetrical wire twisting seats make opposite displacement operations, so that the lead-in reel is moved out of the positioning holes on both sides of the wire twisting reel, and the wire twisting reel is removed from between the wire twisting seats. When installing, the wire twisting reel is placed on the top surface of the machine base, and after the positioning rod is aligned with the positioning hole, the hand wheel is rotated in the opposite direction to make the wire twisting seat move relatively, so that the wire twisting reel is installed between the wire twisting seats, thereby facilitating the disassembly and assembly operations when replacing the wire twisting reel and improving work efficiency.

[0003] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, a wire combining disk is provided on one side of the lead disk to twist the single wires. However, the fixed structure of the wire combining holes on the wire combining disk cannot adapt to different wire strand diameters according to the change in the number of single wires. When the wires are combined, the new wire strands formed by twisting are easily scratched against the edges of the wire combining holes, causing certain losses, thereby leading to an increase in the loss rate during the production and processing of the copper wire.

[0004] How to invent a copper wire twisting machine to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a copper wire stranding machine, including a frame 1, a winding assembly 2 is arranged at one end of the frame 1, a mounting frame 4 is arranged at the other end of the frame 1, a winding roller 5 is rotatably mounted on the mounting frame 4, the winding assembly 2 and the winding roller 5 are respectively connected to corresponding driving devices, a closing assembly 3 is arranged between the winding assembly 2 and the winding roller 5, the closing assembly 3 includes a fixed disk 301, the fixed disk 301 is fixedly connected to the frame 1 through a connecting piece, and a rotating disk 302 is rotatably connected to the surface of one side of the fixed disk 301 A through groove is provided in the middle of the fixed disk 301 and the rotating disk 302. Four straight slide grooves 305 evenly distributed in an annular shape are provided on the surface of the fixed disk 301 on one side facing the rotating disk 302. A slide rod 306 is slidably installed in each straight slide groove 305. One end of each slide rod 306 extends into the through groove and is fixedly connected to a U-shaped mounting portion 307. A guide limiting wheel 308 is rotatably installed between the inner walls on both sides of each U-shaped mounting portion 307. A linkage mechanism is provided on the rotating disk 302 to connect with all the slide rods 306.

[0024] It should be noted that the winding assembly 2, the fixed disk 301 and the rotating disk 302 are coaxially arranged.

[0025] See also Figure 3 and Figure 4An arc-shaped annular groove is formed on the outer wall of each guide limiting wheel 308 .

[0026] Arranging an arcuate annular groove on the outer wall of the guide limiting wheel 308 can further limit the combined wire strands to avoid friction between the wire strands and the inner wall of the through groove and cause loss, and can also reinforce the twisted wire strands to prevent loosening.

[0027] Furthermore, a protective rubber pad is arranged in each arc-shaped annular groove.

[0028] By arranging a protective rubber pad on the inner wall of the arc-shaped annular groove, the protection effect on the outer wall of the wire strand can be improved, and the loss rate during the processing and production process caused by wear can be reduced.

[0029] Furthermore, an annular groove 303 is provided on a surface of the fixed disk 301 facing the rotating disk 302 , and an annular slider 304 is slidably connected in the annular groove 303 . The annular slider 304 is arranged on a surface of the rotating disk 302 facing the fixed disk 301 .

[0030] The fixed disk 301 and the rotating disk 302 are connected together through the coordinated rotation of the annular groove 303 and the annular slider 304, so that the rotating disk 302 can rotate independently relative to the fixed disk 301. When the rotating disk 302 rotates independently, all the slide rods 306 can be driven to move through the driving mechanism, thereby adjusting the spacing between all the guide limit wheels 308 and reducing limitations in use.

[0031] Furthermore, the linkage mechanism includes four circular arc-shaped grooves 310 evenly distributed on the surface of one side of the rotating disk 302, each arc-shaped groove 310 is provided with a linkage column 309, one end of each linkage column 309 is fixedly connected to the surface of one side of the corresponding slide rod 306, and the rotating disk 302 is also connected to the driving mechanism.

[0032] When the rotating disk 302 rotates independently relative to the fixed disk 301, the positions of all the arc-shaped slide grooves 310 on the rotating disk 302 will also change relatively. Since the distances between the two ends of each arc-shaped slide groove 310 and the center of the rotating disk 302 are different, the linkage column 309 inside the arc-shaped slide groove 310 will be squeezed when it moves. The linkage column 309 drives all the slide rods 306 to slide synchronously in the same direction in the straight slide groove 305, thereby changing the distance between all the guide limit wheels 308, which can be flexibly adjusted according to the diameter of the wire strands after twisting.

[0033] Furthermore, the driving mechanism includes a ring gear 311 arranged on the outer wall of the rotating disk 302, the ring gear 311 is meshingly connected with a side gear 312, the gear 312 is fixedly sleeved on one end of the output shaft of the driving motor 313, the driving motor 313 is fixedly mounted on a side surface of the mounting plate 314, and the mounting plate 314 is fixedly connected to a side surface of the fixed disk 301 away from the rotating disk 302.

[0034] When the driving motor 313 is started to drive the gear 312 to rotate, the meshing connection between the gear 312 and the ring gear 311 can drive the rotating disk 302 to rotate independently relative to the fixed disk 301, thereby driving all the sliding rods 306 to move synchronously in the same direction to adjust the distance between all the guide limit wheels 308.

[0035] See also Figure 2 The winding assembly 2 includes a distribution plate 201, on the surface of one side of the distribution plate 201, a connecting shaft 202 is fixedly connected, one end of the connecting shaft 202 is connected to the corresponding driving device, and a plurality of lead holes 203 evenly distributed in an annular shape are opened through the surface of one side of the distribution plate 201. One side of each lead hole 203 is located on the surface of the distribution plate 201 and is fixedly connected to a corresponding placement plate 204. One end of a wire roller shaft 205 is rotatably installed on the surface of one side of each placement plate 204, and a limiting plate 206 is provided on the other end of each wire roller shaft 205.

[0036] When in use, the single-wire roller is sleeved on the corresponding wire roller rotating shaft 205 and limited by the limiting plate 206. After one end of each single wire passes through the corresponding lead-in hole 203 through the wire distribution disk 201, all the single-wire ends are merged and passed through four guide limiting wheels 308 and fixed on the winding roller 5. The corresponding driving device is started to drive the wire distribution disk 201 to rotate as a whole. The synthesized wire strands are restricted by the four guide limiting wheels 308 and the lead-in hole 203 and are twisted together as the wire distribution disk 201 rotates, and the winding is completed by the rotation of the winding roller 5.

[0037] Furthermore, a threaded hole 207 is formed on the surface of one end of each line roller shaft 205 , and a threaded column 208 is formed on the surface of one side of each limiting plate 206 . Each threaded column 208 is threadedly connected in the corresponding threaded hole 207 .

[0038] The wire roller shaft 205 and the limit plate 206 are connected by threads for easy assembly and disassembly, thereby improving convenience during use.

[0039] Furthermore, the two driving devices are respectively a first motor 6 and a second motor 7. The first motor 6 is fixedly mounted on one end of the upper surface of the frame 1, and the second motor 7 is fixedly mounted on a side surface of the mounting frame 4. One end of the connecting shaft 202 is fixedly connected to one end of the output shaft of the first motor 6, and one end of the winding roller 5 is fixedly connected to one end of the output shaft of the second motor 7.

[0040] The first motor 6 and the second motor 7 drive the wire distribution plate 201 and the winding roller 5 to rotate respectively. In actual use, the rotation speeds of the two can be adjusted respectively to keep the single wire and the wire strands in a straight state at all times to avoid affecting the twisting effect of the wire strands.

[0041] Working principle: When in use, the single-wire roller sleeve is set on the corresponding wire roller shaft 205 and limited by the limit plate 206. One end of each single wire is passed through the corresponding lead hole 203 through the distribution disk 201 and then all the single wire ends are merged. According to the diameter of the merged wire strands, the drive motor 313 is started to drive the rotating disk 302 to rotate independently relative to the fixed disk 301. The positions of all the arc-shaped slide grooves 310 on the rotating disk 302 will also change relatively. Because the distances between the two ends of each arc-shaped slide groove 310 and the center of the rotating disk 302 are different, when the arc-shaped slide groove 310 is displaced, the linkage column 309 inside it will be squeezed, and all the slide rods 306 are driven by the linkage column 309 to slide synchronously in the same direction in the straight slide groove 305, thereby changing all the guide limits. The distance between the wheels 308 is such that the outer wall of the wire strand is fitted into the arc-shaped annular groove provided on the surface of the four guide limiting wheels 308 for limiting, and then the end of the wire strand is fixed on the winding roller 5, and the first motor 6 and the second motor 7 are started at the same time to rotate the wire distribution disk 201 and the winding roller 5, and the winding roller 5 pulls one end of the wire strand for winding, and the wire strand is restricted by the guide limiting wheels 308 and the single wire is restricted by the lead hole 203, so that it is continuously twisted together and wound toward one side of the winding roller 5. By setting four guide limiting wheels 308 to limit the wire strand and the conductor, it can be ensured that the wire strand will not contact the edge of the through groove to cause wear, thereby reducing the loss rate in the production process. At the same time, the four guide limiting wheels 308 can also adjust the spacing between them, thereby reducing limitations in use.

[0042] It should be noted that the specific models and specifications of the drive motor 313, the first motor 6 and the second motor 7 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0043] The power supply and principles of the driving motor 313, the first motor 6 and the second motor 7 are clear to those skilled in the art and will not be described in detail herein.

[0044] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
