[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] 1. The constant tension device of the bundle twisting machine can ensure that the tension of the copper wire remains constant during the pay-off process through the automatic adjustment function of the constant mechanism. The constant mechanism can automatically adjust according to the actual tension to adapt to different production conditions and copper wire characteristics, making the equipment more flexible. Multiple rollers are set so that the roller surface of the roller is wavy. When the copper wire line contacts the roller, the upper and lower rollers are staggered to produce heavy squeezing pressure, causing the copper wire to bend locally and increase the tension. At this time, the pulled copper wire is locally bent to restore its tension, avoiding excessive relaxation when entering the bundle twisting machine chamber, resulting in uneven stranded conductors, thereby achieving the effect of uniform tension feeding.

[0019] 2. The bundle twisting machine has a constant wire tension device. The cleaning mechanism removes dust and impurities on the copper wire through a cleaning sponge to ensure that the surface of the copper wire is clean, thereby improving the overall appearance and quality of the copper wire. The cleaned surface of the copper wire is easier for lubricating oil to adhere to, which enhances the lubrication effect and reduces the wear of the copper wire during the wire-paying process. The lubricating mechanism forms a lubricating film on the surface of the copper wire, which significantly reduces the wear of the copper wire during the wire-paying process. This not only extends the service life of the copper wire, but also reduces material loss in the production process. The synergistic effect of the constant mechanism and the lubricating mechanism makes the copper wire pay-off process smoother, reduces downtime caused by unstable tension or wear, and thus improves production efficiency.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 The constant tension device for the wire-laying machine in this embodiment includes a frame 1, and a constant mechanism 2 for maintaining constant tension is provided on the front and rear inner walls of the frame 1. A lubrication mechanism 3 for reducing copper wire wear is provided at the bottom of the frame 1 and on the right side of the constant mechanism 2. A cleaning mechanism 4 for cleaning the copper wire before wire-laying is provided between the front and rear inner walls of the frame 1 and on the right side of the lubrication mechanism 3.

[0033] In this embodiment, a controller is provided on the outer side of the frame 1 , and four adjustable feet 5 are provided on the lower surface of the frame 1 .

[0034] See also Figures 2 to 3 In order to maintain constant tension, the constant mechanism 2 in this embodiment includes four adjustment ports 21 respectively opened on the inner walls of the front and rear sides of the frame 1, and the inner walls of the eight adjustment ports 21 are slidably provided with adjustment blocks 22, and the opposite sides of the front and rear adjustment blocks 22 are fixed with mounting seats 23, and the opposite sides of the front and rear mounting seats 23 are provided with tension sensors 24, and the interiors of the front and rear tension sensors 24 are sleeved with connecting shafts 25, and the outer side of the connecting shaft 25 is fixed with rollers 26. The copper wire is preliminarily processed by the cleaning mechanism 4 and the lubrication mechanism 3, and the copper wire is passed around the four rollers 26 in turn, two of which are driven by the cylinder 274 to adjust to the same plane height and remain fixed, and the other two rollers 26 can freely adjust the height according to the tension, and the outer side of the roller 26 is provided with an adjusting member 27 for adjusting the height of the roller 26 to change the tension. The two rollers 26 with fixed heights serve as the basis for tension detection, and the passing pressure is detected when the copper wire passes.

[0035] The adjusting member 27 includes two limit rings 271 fixed on the outside of the roller 26, and the two limit rings 271 are respectively located on the front and rear sides of the outer surface of the roller 26. A cylinder 274 is fixed to the inner bottom wall of the frame 1, and a U-shaped frame 273 is fixed to the outside of the output shaft of the cylinder 274. Lifting frames 272 are fixed at both ends of the U-shaped frame 273. When the tension sensor 24 detects that the tension does not reach the set value, the controller drives the output shaft of the cylinder 274 to retract and retract, and then cooperates with the U-shaped frame 273 and the lifting frame 272 to drive the roller 26 to adjust the height.

[0036] In this embodiment, telescopic rods 275 are fixed to the inner bottom wall of the frame 1 and are located on both sides of the front and rear of the cylinder 274, and the top ends of the two telescopic rods 275 are fixed to the lower surface of the U-shaped frame 273. Through the extension and contraction of the cylinder 274, when the lifting frame 272 moves down, the roller 26 moves down with the lifting frame 272 under the action of gravity, and the U-shaped frame 273 and the lifting frame 272 drive the adjustment roller 26 to automatically adjust the tension to keep it constant. The two telescopic rods 275 each include a supporting sleeve and an inner rod slidably arranged inside the supporting sleeve. The inner wall of the lifting frame 272 is embedded with a plurality of balls, and the balls are The cylinder 26 is placed inside the lifting frame 272 and is located on the outside of the ball. The lifting frame 272 is embedded with a ball to ensure that the cylinder 26 can rotate freely, reduce friction, and continuously monitor the data of the tension sensor 24 to ensure that the tension is maintained within the set range. The four cylinders 26 are adjustable and staggered up and down to form a wavy structure. This design allows the copper wire to be partially bent when passing through due to the staggered pressure of the cylinder 26, thereby increasing the tension. At this time, the pulled copper wire restores its tension through local bending, avoiding it from being too loose when entering the bundle twisting machine chamber, resulting in the stranded conductor being not round.

[0037] It should be noted that the tension sensor 24 is an annular tension sensor, which usually contains a strain gauge inside. The strain gauge is firmly attached to the substrate as an electrical conductor. When the substrate is stretched or compressed, the strain gauge will be correspondingly lengthened or shortened, resulting in a change in resistance value. This change can be used to calculate the force by measuring the change in resistance value.

[0038] See also Figures 4 to 7 In order to reduce the wear of the copper wire, the lubrication mechanism 3 in this embodiment includes an oil storage box 31 fixed to the bottom wall of the frame 1 and located on the right side of the roller 26. The inner walls of the front and rear sides of the oil storage box 31 are provided with rotation holes, and the inner walls of the two rotation holes are rotatably connected with a rotating shaft 32. A lubrication roller 33 is fixed on the outer side of the rotating shaft 32 to ensure that one side of the lubrication roller 33 is immersed in the lubrication oil. A layer of lubrication oil is attached to the surface of the lubrication roller 33. An auxiliary roller 34 is rotatably connected to the lubrication roller 33 between the inner walls of the front and rear sides of the frame 1 and above the lubrication roller 33 through a bearing. After the copper wire is cleaned, The oil storage box 31 is provided with a plurality of dividing rollers 35 for rotating at the bottom of the frame 1 and on the left side of the oil storage box 31. The plurality of dividing rollers 35 can further separate and pay out the copper wires, ensuring that the copper wires can enter the constant mechanism 2 evenly, reducing the crossing and entanglement of the copper wires. The left and right walls of the inner cavity of the oil storage box 31 are fixed with three thrust springs 36, and the other ends of the left and right groups of thrust springs 36 are fixed with scrapers 37, and the front and rear ends of the scrapers 37 are fixed with round blocks 38.

[0039] In addition, two circular grooves are provided on the front and rear walls of the inner cavity of the oil storage box 31, and the round block 38 is rotatably connected to the inside of the circular groove, so that the scraper 37 can be stably located in the oil storage box 31, so that when the thrust spring 36 pushes the scraper 37 to contact the lubrication roller 33, the scraper 37 can scrape the lubricating oil on the surface of the lubrication roller 33, so as to ensure that the lubricating oil is evenly distributed on the surface of the lubrication roller 33, and can effectively control the flow and distribution of the lubricating oil, reduce the excessive accumulation of the lubricating oil on the surface of the lubrication roller 33, thereby reducing the waste of the lubricating oil.

[0040] In this embodiment, a lubrication port is provided on the upper surface of the oil storage box 31, and the lubrication roller 33 is rotatably connected between the inner walls on the left and right sides of the lubrication port. The rotation of the lubrication roller 33 and the supply of lubricating oil are regularly checked to ensure the normal operation of the lubrication system. The lubricating oil is replenished or the lubrication roller 33 is replaced when necessary. The upper surface of the oil storage box 31 is connected to an oil filling funnel, and the interior of the oil storage box 31 is filled with lubricating oil through the oil filling funnel. When the copper wire is paid out, the lubrication roller 33 is driven to rotate. The lubricating oil on the surface of the lubrication roller 33 adheres to the copper wire as the copper wire moves to form a lubricating film. The lubricating film reduces the wear of the copper wire in the subsequent pay-off process, ensures that the surface of the copper wire is smooth, and reduces friction.

[0041] See also Figures 8 to 10 In order to clean the copper wire before paying out, the cleaning mechanism 4 in this embodiment includes a cleaning box 41 fixed between the inner walls of the front and rear sides of the frame 1 and located on the right side of the oil storage box 31. A plurality of supporting springs 42 are fixed to the inner top wall of the cleaning box 41. A push plate 43 is fixed to the bottom of the plurality of supporting springs 42. A cleaning sponge 44 is provided on the lower surface of the push plate 43. Multiple strands of copper wire are taken out from the wire reel, dispersed into single strands, and passed through the wire distribution pipe 46 to enter the cleaning box 41. The supporting spring 42 pushes the push plate 43 to move, so that the cleaning sponge 44 contacts the surface of the copper wire. A wire passing plate 45 is fixed inside the cleaning box 41 and below the cleaning sponge 44. As the copper wire moves, the cleaning sponge 44 cleans the dust and impurities on the surface of the copper wire. The surface of the copper wire after cleaning is clean, which is convenient for the subsequent attachment of lubricating oil. A plurality of branching grooves are opened on the upper surface of the wire passing plate 45. The left and right sides of the cleaning box 41 are respectively connected with branching pipes 46 corresponding to the positions of the plurality of branching grooves. A box cover 47 is provided at the top of the cleaning box 41. Three plug plates 48 are fixed to the top of the cleaning sponge 44. Two plug blocks 49 are fixed to the left and right sides of the lower end of the box cover 47. The internal threads of the plug blocks 49 are connected to threaded rods 410. The opposite ends of the left and right threaded rods 410 are fixed with operating blocks 411.

[0042] Meanwhile, three T-shaped inserting slots are formed at the front end of the push plate 43 , and the inserting plate 48 is inserted into the T-shaped inserting slots so that the cleaning sponge 44 can be installed at the lower end of the push plate 43 .

[0043] In addition, installation slots for inserting the plug 49 therein are provided on both the left and right sides of the top of the cleaning box 41, and two through holes are provided on both the left and right ends of the cleaning box 41, which are connected to the installation slots, so that the threaded rod 410 is threadedly connected to the inside of the through holes and can be moved into the installation slots.

[0044] Moreover, the opposite walls of the left and right groups of plug blocks 49 are each provided with a threaded hole for the threaded rod 410 to pass through, and the threaded rod 410 is threadedly connected to the inside of the threaded hole so that the plug block 49 can be installed and fixed in the installation slot hole of the cleaning box 41.

[0045] In this embodiment, the opposite ends of the left and right branch tubes 46 are both provided with flared openings, and the end faces of the branch tubes 46 are arc-shaped. The cleaned copper wire passes through the branch tube 46 on the other side and out of the cleaning box 41. The synergistic effect of the support spring 42 and the push plate 43 ensures that the copper wire will not be damaged during the cleaning process, and the arc-shaped end face ensures that the copper wire will not be scratched or worn when entering.

[0046] The working principle of the above embodiment is:

[0047] (1) Take out multiple strands of copper wire from the wire reel, disperse them into single strands, pass them through the wire splitter 46, and enter the cleaning box 41. The support spring 42 pushes the push plate 43 to move, so that the cleaning sponge 44 contacts the surface of the copper wire. As the copper wire moves, the cleaning sponge 44 cleans the dust and impurities on the surface of the copper wire. After cleaning, the surface of the copper wire is clean, which is convenient for the subsequent attachment of lubricating oil. After cleaning, the copper wire passes through the other side of the wire splitter 46 and goes out of the cleaning box 41. The synergistic effect of the support spring 42 and the push plate 43 ensures that the copper wire will not be damaged during the cleaning process.

[0048] (2) Ensure that one side of the lubricating roller 33 is immersed in lubricating oil. A layer of lubricating oil is attached to the surface of the lubricating roller 33. After the copper wire is cleaned, it enters the gap between the lubricating roller 33 and the auxiliary roller 34. When the copper wire is unwinding, it drives the lubricating roller 33 to rotate. The lubricating oil on the surface of the lubricating roller 33 adheres to the copper wire as it moves, forming a lubricating film. The lubricating film reduces the wear of the copper wire during the subsequent unwinding process, ensures that the surface of the copper wire is smooth, and reduces friction. Regularly check the rotation of the lubricating roller 33 and the supply of lubricating oil to ensure that the lubrication system works normally. If necessary, add lubricating oil or replace the lubricating roller 33. Multiple wire splitting rollers 3 5 can further separate and release the copper wires, ensuring that the copper wires can evenly enter the constant mechanism 2, reducing the crossing and entanglement of the copper wires, and when the lubricating roller 33 is lubricating, the two groups of thrust springs 36 on the left and right push the two scrapers 37 to move relative to each other, so that the opposite ends of the two scrapers 37 abut against the left and right walls of the lubricating roller 33, so that the scrapers 37 can scrape off the excessive lubricating oil on the surface of the lubricating roller 33, so as to ensure that the lubricating oil is evenly distributed on the surface of the lubricating roller 33, and effectively control the flow and distribution of the lubricating oil, reduce the excessive accumulation of the lubricating oil on the surface of the lubricating roller 33, thereby reducing the waste of the lubricating oil.

[0049] (3) The copper wire is initially processed by the cleaning mechanism 4 and the lubricating mechanism 3, and then passed through four rollers 26 in sequence. Two of the rollers 26 are driven by the cylinder 274 to be adjusted to the same plane height and kept fixed. The other two rollers 26 can freely adjust the height according to the tension. The two rollers 26 with fixed heights serve as the basis for tension detection. The passing pressure of the copper wire is detected when it passes. When the tension sensor 24 detects that the tension does not reach the set value, the controller drives the cylinder 274 output shaft to extend and retract, and then cooperates with the U-shaped frame 273 and the lifting frame 272 to drive the roller 26 to adjust the height. Through the extension and retraction of the cylinder 274, when the lifting frame 272 moves down, the roller 26 is under the action of gravity. The lower part will move down together with the lifting frame 272, and the U-shaped frame 273 and the lifting frame 272 drive the adjustment roller 26 to automatically adjust the tension to keep it constant. The lifting frame 272 is embedded with balls to ensure that the roller 26 can rotate freely, reduce friction, and continuously monitor the data of the tension sensor 24 to ensure that the tension is maintained within the set range. The four rollers 26 can be adjusted and staggered up and down to form a wavy structure. This design makes the copper wire partially bend due to the staggered pressure of the roller 26 when passing through, thereby increasing the tension. At this time, the tension of the pulled copper wire is restored by local bending, avoiding excessive relaxation when entering the bundle twisting machine chamber, resulting in uneven stranded conductors.

[0050] In addition, after the cleaning sponge 44 has been used for a long time, it will be worn out. By rotating the left and right operating blocks 411, the left and right operating blocks 411 drive the left and right threaded rods 410 to rotate and move them back to back, so that the left and right threaded rods 410 are moved out of the threaded holes of the plug block 49 and moved into the installation slots of the cleaning box 41. The above steps are repeated to move the left and right threaded rods 410 on the other side out of the plug block 49, so that the cover plate 47 can be removed from the top of the cleaning box 41. When the cover plate 47 is taken out from the top of the cleaning box 41, the cover plate 47 will drive the push plate 43 to move out of the cleaning box 41 through a plurality of support springs 42, and the push plate 43 can drive the cleaning sponge 44 to move out of the cleaning box 41, and by moving the cleaning sponge 44 forward from under the push plate 43, the three The plug plate 48 can be removed from the T-shaped plug-in slot of the push plate 43, so that the cleaning sponge 44 can be removed from under the push plate 43, and the plug plate 48 of the new cleaning sponge 44 can be inserted into the T-shaped plug-in slot of the push plate 43, and the cover plate 47 is placed on the top of the cleaning box 41, so that the new cleaning sponge 44 is located in the cleaning box 41, and at the same time, the two groups of plug blocks 49 of the cover plate 47 are plugged into the two groups of mounting slots of the cleaning box 41, and the left and right groups of operating blocks 411 are rotated so that the left and right groups of operating blocks 411 drive the left and right groups of threaded rods 410 to move relative to each other and move into the threaded holes of the plug blocks 49, so that the plug blocks 49 can be fixedly installed in the mounting slots, the cover plate 47 is installed on the top of the cleaning box 41, and the replaced cleaning sponge 44 is installed in the cleaning box 41, so as to facilitate regular replacement of the cleaning sponge 44.
