Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal wire braiding machine technology, specifically to a wire feeding transition mechanism for a braiding machine. Background Technology
[0002] Metal braiding machines are specialized pieces of machinery designed to weave metal wires into mesh structures, playing a vital role in industrial production. They have a wide range of applications, capable of manufacturing various types of metal mesh, including filter screens, sieves, and protective netting, meeting the production needs of different industries such as construction, mining, chemical, and agriculture.
[0003] In the operation of a metal braiding machine, the wire unwinding process is crucial. Typically, the wire is placed in a coil on a rotating unwinding frame. The rotating frame provides stable unwinding force to the wire, ensuring it unwinds smoothly and easily from the coil and enters the braiding machine. This design effectively prevents problems such as tangling, knotting, or uneven tension during the unwinding process, laying a solid foundation for subsequent braiding steps.
[0004] To ensure the stability of the wire feeding in the braiding machine, multiple wire feeders containing wire spools are strategically positioned during operation. Specifically, these feeders are fixed to the ground at intervals, maintaining a safe distance between them. This ensures that the wires drawn from different feeders do not interfere with each other as they enter the braiding machine, preventing tangling or contact that could affect braiding quality and efficiency.
[0005] However, even with the aforementioned spacing measures, some safety hazards still exist during the wire feeding process. Firstly, the wire is prone to swaying and shaking along the transmission path between the feeder and the braiding machine. This not only affects the transmission accuracy of the wire but may also cause it to collide with surrounding equipment or personnel. Secondly, when the wire on the feeder is fully pulled out, because one end remains fixed inside the braiding machine while the other end loses support, it may instantly bounce towards the braiding machine under tension. This bouncing behavior is extremely dangerous, potentially causing personal injury to operators or damage to the braiding machine, thereby affecting the safety and stability of the entire production process. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a wire feeding transition mechanism for braiding machines, which improves the stability and safety of the process of metal wire entering the braiding machine from the pay-off frame.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a wire feeding transition mechanism for a braiding machine, comprising an equipment end support assembly and a wire feeding frame end support assembly, wherein a wire guide assembly is connected between the equipment end support assembly and the wire feeding frame end support assembly, and the metal wire on the wire feeding frame passes through the wire guide assembly near the wire feeding frame end support assembly and then passes through the end of the wire guide assembly near the equipment end support assembly and connects to the braiding machine.
[0008] Furthermore, the guide wire assembly includes a front tube and a rear tube, with several telescopic tubes connecting the front tube and the rear tube. The front tube is connected to the equipment end support assembly, and the end of the rear tube furthest from the front tube is connected to the wire feeding frame end support assembly.
[0009] Furthermore, several limiting blocks are fixedly connected to the inner walls of the front end tube and several telescopic tubes near the rear end tube. Several limiting grooves matching the limiting blocks are opened on the outer walls of the rear end tube and several telescopic tubes. The limiting blocks are slidably connected to the limiting grooves respectively. The inner wall diameter and outer wall diameter of the front end tube, several telescopic tubes and the rear end tube decrease in sequence and are slidably fitted in sequence.
[0010] Furthermore, the ends of the front and rear tubes that are far apart from each other are fixedly connected and connected to a horn ring.
[0011] Furthermore, the equipment end support assembly includes a first support rod and a first base. The two ends of the first support rod are respectively connected to the first base and the end of the front end tube away from the rear end tube. The first base is fixedly connected to the ground by multiple bolts passing through preset bolt holes.
[0012] Furthermore, the first support rod includes an internally threaded tube and an externally threaded rod. The outer wall of the externally threaded rod is threadedly connected to the inner wall of the internally threaded tube. The end of the internally threaded tube away from the externally threaded rod is fixedly connected to the first base, and the end of the externally threaded rod away from the internally threaded tube is connected to the front end tube.
[0013] Furthermore, a first U-shaped frame is fixedly connected to the end of the external threaded rod away from the internal threaded tube, and the outer walls on both sides of the front tube are rotatably connected to the two ends of the first U-shaped frame through a rotating shaft.
[0014] Furthermore, the wire-laying frame end support assembly includes a second support rod and a second base. The two ends of the second support rod are respectively connected to the second base and the end of the rear tube away from the front tube. The second base is fixedly connected to the ground by multiple bolts passing through preset bolt holes.
[0015] Furthermore, the second support rod includes a sleeve and a telescopic rod. The outer wall of the telescopic rod is slidably connected to the inner wall of the sleeve. The end of the sleeve away from the telescopic rod is connected to the second base. The end of the telescopic rod away from the sleeve is connected to the end of the rear tube. Several anti-detachment blocks are fixedly connected to the outer wall of the telescopic rod near the sleeve. Several sliding grooves are opened on the inner wall of the sleeve, and the several anti-detachment blocks are slidably connected to the several sliding grooves respectively.
[0016] Furthermore, a second U-shaped frame is fixedly connected to the end of the telescopic rod away from the sleeve. The outer walls on both sides of the end of the rear tube away from the front tube are rotatably connected to the two ends of the second U-shaped frame through a pivot. A U-shaped base frame is fixedly connected to the upper surface of the second base. The end of the sleeve away from the telescopic rod is rotatably connected to the two ends of the U-shaped base frame through a pivot. A movable spring is fixedly connected to the end of the telescopic rod near the sleeve. The other end of the movable spring is fixedly connected to the bottom inner wall of the sleeve.

[0018] This type of braiding machine uses a coiled wire feeding transition mechanism. Through the equipment end support component and the wire feeding frame end support component, the wire guide component is set between the braiding machine inlet and the wire feeding frame. The metal wire on the wire feeding frame passes through the wire guide component and connects to the braiding machine. In this way, the wire guide component restricts the metal wire from the wire feeding frame to the braiding machine inside, ensuring that the metal wire will not shake or bounce around in the operating environment, thus improving the safety and stability of the metal coiled wire feeding process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figures 1 to 5 A wire feeding transition mechanism for a braiding machine includes an equipment end support component 1 and a wire feeding frame end support component 2. A wire guide component 3 is connected between the equipment end support component 1 and the wire feeding frame end support component 2. The metal wire on the wire feeding frame passes through the wire guide component 3 near the wire feeding frame end support component 2 and then passes out from the end of the wire guide component 3 near the equipment end support component 1 and connects to the braiding machine.
[0027] like Figures 1 to 5 As shown, the main improvement of this utility model lies in its ability to limit the metal coil wire between the pay-off frame and the braiding machine, thereby improving the stability and safety of the metal coil wire feeding. Figures 1 to 5 As shown, the wire feeding transition mechanism for the braiding machine in this utility model, during use, installs the wire guide assembly 3 on the feed end of the wire feeder and the braiding machine via the equipment end support assembly 1 and the wire feeder end support assembly 2. One end of the wire guide assembly 3 faces the feed end of the braiding machine, and the other end faces the wire feeder. The end of the wire coiled on the wire feeder passes through one end of the wire guide assembly 3, then exits from the other end, and finally connects to the feed end of the braiding machine. During the metal wire coil weaving process, the metal wire is confined within the wire guide assembly 3, thereby preventing the metal coil from moving. The wire moves erratically in the processing environment. At the same time, when the metal coil is completely pulled out from the pay-off stand, the tail of the metal coil is ensured to be confined inside the wire guide assembly 3 and gradually move towards the braiding machine. This prevents the tail of the metal coil from ejecting or rebounding, thus improving the safety of the processing environment. It should be noted that the braiding machine has multiple feed ports, and multiple pay-off stands are matched with multiple feed ports. A wire guide assembly 3 is installed between each feed port and the corresponding pay-off stand to guide the feeding of the metal coil. Multiple wire guide assemblies 3 can be distributed side by side or arranged radially at the feed end of the braiding machine.
[0028] like Figures 1 to 4 As shown, the wire guide assembly 3 includes a front tube 31 and a rear tube 32. Several telescopic tubes 33 connect the front tube 31 and the rear tube 32. The front tube 31 is connected to the equipment end support assembly 1, and the end of the rear tube 32 away from the front tube 31 is connected to the wire feeding frame end support assembly 2. The metal coiled wire enters from the rear tube 32, passes through the multiple telescopic tubes 33, and then exits from the front tube 31. The multiple telescopic tubes 33 allow for easy adjustment of the length of the entire wire guide assembly 3 between the front tube 31 and the rear tube 32, thereby adapting to the distance between the wire feeding frame and the braiding machine's feed end. This ensures that the front tube 31 is as close as possible to the braiding machine's feed end, while the rear tube 32 is as close as possible to the wire feeding frame, improving the guiding and feeding effect of the metal coiled wire.
[0029] like Figures 1 to 4 As shown, several limiting blocks 34 are fixedly connected to the inner walls of the front end tube 31 and several telescopic tubes 33 near the rear end tube 32. Several limiting grooves 301 matching the limiting blocks 34 are opened on the outer walls of the rear end tube 32 and several telescopic tubes 33. The limiting blocks 34 are slidably connected to the limiting grooves 301 respectively. The inner and outer diameters of the front end tube 31, several telescopic tubes 33 and the rear end tube 32 decrease sequentially and are slidably fitted in sequence. The front end tube 31 and several telescopic tubes 33 are sequentially fitted on the outside of the rear end tube 32, and the sliding of the limiting blocks 34 and the limiting grooves 301 ensures that the two fitted tubes will not fall off.
[0030] like Figures 1 to 4 As shown, the ends of the front tube 31 and the rear tube 32, which are far apart from each other, are fixedly connected and connected to a horn ring 8. The horn ring 8 is installed at the ends of the front tube 31 and the rear tube 32, so that the two ends of the metal coil wire contact with the horn ring 8, thereby reducing the scraping and wear of the end of the wire guide assembly 3 on the outer surface of the metal coil wire and improving the guiding and limiting effect on the metal coil wire.
[0031] like Figure 1 and Figure 2 As shown, the equipment end support assembly 1 includes a first support rod 4 and a first base 5. The two ends of the first support rod 4 are connected to the first base 5 and the end of the front end tube 31 furthest from the rear end tube 32, respectively. The first base 5 is fixedly connected to the ground via multiple bolts passing through pre-set bolt holes. The front end tube 31 is supported at the feed end of the braiding machine by the first support rod 4, and the first base 5 is fixedly installed on the ground or on the base at the feed end of the braiding machine by bolts, ensuring that the outlet of the front end tube 31 faces the feed inlet of the braiding machine, so that the metal coiled wire can enter the braiding machine more smoothly for processing.
[0032] like Figure 1 and Figure 2As shown, the first support rod 4 includes an internally threaded tube 41 and an externally threaded rod 42. The outer wall of the externally threaded rod 42 is threadedly connected to the inner wall of the internally threaded tube 41. The end of the internally threaded tube 41 away from the externally threaded rod 42 is fixedly connected to the first base 5, and the end of the externally threaded rod 42 away from the internally threaded tube 41 is connected to the front end tube 31. When installing the first support rod 4, the internally threaded tube 41 is rotated outside the externally threaded rod 42 according to the height of the braiding machine's feed port from the ground, thereby adjusting the overall length of the internally threaded tube 41 and the externally threaded rod 42. This ensures that after the first support rod 4 is installed and fixed, the outlet of the front end tube 31 is flush with the feed port of the braiding machine, so that the metal coil wire can pass more smoothly through the guide wire assembly 3 into the braiding machine.
[0033] like Figure 1 and Figure 2 As shown, the end of the externally threaded rod 42 away from the internally threaded tube 41 is fixedly connected to a first U-shaped frame 43, and the outer walls on both sides of the front end tube 31 are rotatably connected to the two ends of the first U-shaped frame 43 via a pivot. After the first support rod 4 is installed and fixed, the front end tube 31 rotates up and down inside the first U-shaped frame 43 at the top of the first support rod 4 via a pivot, which facilitates the adjustment and installation of the wire feeder end support assembly 2.
[0034] like Figures 1 to 4 As shown, the wire feeder end support assembly 2 includes a second support rod 6 and a second base 7. The two ends of the second support rod 6 are connected to the second base 7 and the end of the rear end tube 32 furthest from the front end tube 31, respectively. The second base 7 is fixed to the ground by multiple bolts passing through pre-set bolt holes. When installing the wire feeder end support assembly 2, the rear end tube 32 is supported by the second support rod 6, and the second base 7 is fixed to the ground using bolts, thus completing the installation of the rear end of the wire guide assembly 3.
[0035] like Figures 1 to 4As shown, the second support rod 6 includes a sleeve 61 and a telescopic rod 62. The outer wall of the telescopic rod 62 is slidably connected to the inner wall of the sleeve 61. The end of the sleeve 61 away from the telescopic rod 62 is connected to the second base 7. The end of the telescopic rod 62 away from the sleeve 61 is connected to the end of the rear tube 32. Several anti-detachment blocks 63 are fixedly connected to the outer wall of the telescopic rod 62 near the sleeve 61. Several sliding grooves 601 are opened on the inner wall of the sleeve 61. Several anti-detachment blocks 63 are slidably connected to several sliding grooves 601 respectively. After the second base 7 is installed and fixed on the ground, when the metal coil wire passes through the wire guide assembly 3 from the wire feeding frame and is guided for feeding, the wire exit position of the metal coil wire continuously moves up and down on the wire feeding frame as it continuously winds out of the wire feeding frame. At this time, the metal coil wire can drive the wire guide assembly 3 to move up and down accordingly. At this time, the telescopic rod 62 moves up and down in the sleeve 61, making the wire exit of the metal coil wire on the wire feeding frame smoother. At the same time, when the telescopic rod 62 moves up and down in the sleeve 61, the connection between the telescopic rod 62 and the sleeve 61 can be prevented from disengaging through the limiting sliding between the anti-detachment block 63 and the slide groove 601, thereby improving the support stability of the wire feeding frame end support assembly 2.
[0036] like Figures 1 to 4 As shown, the end of the telescopic rod 62 away from the sleeve 61 is fixedly connected to the second U-shaped frame 21. The outer walls on both sides of the end of the rear tube 32 away from the front tube 31 are rotatably connected to the two ends of the second U-shaped frame 21 through a pivot. The upper surface of the second base 7 is fixedly connected to the U-shaped base frame 22. The end of the sleeve 61 away from the telescopic rod 62 is rotatably connected to the two ends of the U-shaped base frame 22 through a pivot. The end of the telescopic rod 62 near the sleeve 61 is fixedly connected to the movable spring 64. The other end of the movable spring 64 is fixedly connected to the bottom inner wall of the sleeve 61. As the metal coil drives the wire guide assembly 3 to move up and down, the telescopic rod 62 is connected to the rear tube 32 through the second U-shaped frame 21 and rotates. At the same time, the bottom of the sleeve 61 is connected to the second base 7 through the U-shaped base frame 22 and rotates. This allows the tail end of the wire guide assembly 3 to move up and down with the metal coil on the wire feeding frame, ensuring that the rear tube 32 is always aligned with the wire feeding position of the wire feeding frame. This makes it easier for the metal coil to enter the wire guide assembly 3 from the wire feeding frame, reducing the scraping force between the outer wall of the metal coil and the end of the rear tube 32, and improving the guiding and feeding effect of the metal coil.
[0037] In use, the lengths of the internal threaded tube 41 and the external threaded rod 42 are first adjusted to ensure that after the first base 5 is installed and fixed, the outlet of the front tube 31 is aligned with the feed port of the braiding machine. Then, the rear tube 32 is pulled towards the pay-off frame. Through multiple telescopic tubes 33, the length of the entire guide wire assembly 3 is adapted to the distance between the pay-off frame and the braiding machine. Then, the second base 7 is fixed on the ground near the pay-off frame. Finally, the metal coil wire on the pay-off frame is inserted into the rear tube 32 and exited from the front tube 31 to connect with the feed port of the braiding machine. The rear tube 32 extends and retracts at the top of the telescopic rod 62. The metal coil wire supports the rear tube 32 at a certain height. As the metal coil wire is pulled out from the pay-off frame, the position of the metal coil wire pulled out on the pay-off frame moves up and down, which drives the rear tube 32 to move up and down, thereby ensuring that the rear tube 32 is always aligned with the position of the metal coil wire pulled out, improving the stability of the metal coil wire being discharged from the pay-off frame.
