Description

Technical Field

[0001] This utility model relates to the field of computerized horizontal knitting machine technology, and in particular to a wire conveying mechanism for a computerized horizontal knitting machine. Background Technology

[0002] A computerized flat knitting machine is a double-needle plate-latch weft knitting machine. Its cam mechanism acts like a set of planar cams. The needle feet can enter the grooves of the cams, and by moving the cams, the needles are forced to move up and down rhythmically within the needle grooves of the needle plate. Through the actions of the needle hook and the needle latch, the yarn is knitted into fabric. During the upward movement of the needle, the loops gradually exit the needle hook, the needle latch opens, and the loops are hung on the needle bar. During the downward movement of the needle, the needle hook catches newly placed yarn and pulls it to bend into a loop. Simultaneously, the existing loops exit the needle hook, and the new loops pass through the old loops, connecting in series. Numerous loops are interconnected to form the knitted fabric. The wire feed mechanism is a device in computerized flat knitting machines used for direct fabric raising without generating waste yarn.

[0003] Application No. CN201921596021.9 proposes a wire conveying mechanism for a computerized flat braiding machine, including a base plate, a wire feeder, a wire feeding pressure fastener, a stepper motor, a synchronous belt, a synchronous pulley A, a synchronous pulley B, etc. The wire feeding pressure fastener of the wire conveying mechanism of this utility model can flexibly adjust the flexible pressure on the wire, and cooperate with the wire feeder to complete the task of high-precision quantitative conveying of wires of different specifications.

[0004] Existing patented wire conveying mechanisms use a motor-driven wire feeder and a wire feeding pressure fastener at the base plate to convey the wire. In this type of wire feeder, the NATR8 needle roller bearing of the wire feeding pressure fastener applies flexible pressure to the wire, causing the drive wheel of the wire feeder to generate frictional force on the wire for stable conveying. However, the contact force between the needle roller bearing and the wire is relatively low, resulting in poor wire tension at the drive wheel, which affects the quantitative conveying accuracy of the wire. Therefore, we propose a wire conveying mechanism for a computerized flat braiding machine. Utility Model Content

[0005] The main objective of this invention is to provide a wire conveying mechanism for a computerized flat braiding machine. This mechanism incorporates a wire adjustment mechanism at the existing wire feeder, forming the wire conveying mechanism for the computerized flat braiding machine. The design of the wire adjustment mechanism allows for elastic tension adjustment of the wire between the transmission wheels inside the wire feeder during conveying. This ensures precise adjustment of the tension or position of the wire during conveying, guaranteeing the quantitative conveying accuracy of the wire. Furthermore, the L-shaped lifting plate of the wire adjustment mechanism, through the cooperation of the guide groove and the guide plate, provides stable guidance during lifting, which helps ensure the stability and accuracy of the wire during conveying. This mechanism can stably convey the wire and adjust the wire conveying tension as needed, thus improving the weaving efficiency and quality of the computerized flat braiding machine and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wire feeding mechanism for a computerized horizontal braiding machine includes a wire feeder and a drive wheel. The drive wheel is installed inside the wire feeder. The mechanism also includes a wire adjusting mechanism, which comprises a side mounting base, a T-shaped box, a fixed plate, a side cover, an L-shaped lifting plate, a shaft, a drive wheel, a screw, spring A, spring B, and a flange nut. The side mounting base is bolted to the surface of the wire feeder above the drive wheel, and a T-shaped box is welded between the side mounting bases, covering the drive wheel. Ear plates are bolted to the outer sides of the T-shaped box, and a side cover is welded between the ear plates to cover the side opening of the T-shaped box. The top of the box near the side cover of the T-shaped box has a fixed opening for inserting a fixed plate and an L-shaped lifting plate. The fixed plate is integrally formed on the surface of the side cover. The L-shaped lifting plate extends into the vertical plate of the T-shaped box and has a shaft welded to it. A wire-carrying wheel is installed outside the shaft. The top flat plate of the L-shaped lifting plate extends out of the T-shaped box and has a guide hole for inserting a screw. The screw is welded to the top of the T-shaped box. A spring A is sleeved on the screw below the L-shaped lifting plate, and a spring B is sleeved on the upper rod of the screw extending out of the L-shaped lifting plate.

[0008] Furthermore, the top of the L-shaped lifting plate on one side of the guide hole is provided with a guide groove for mounting the guide plate, and the guide plate is welded to the top of the T-shaped box below the L-shaped lifting plate.

[0009] By adopting the above technical solution, the L-shaped lifting plate is mounted on the guide plate above the T-shaped box with a guide slot to obtain guidance during lifting.

[0010] Furthermore, mounting holes are symmetrically provided between the ear plate and the wall of the T-shaped box, and bolts are screwed between the ear plate and the mounting holes of the T-shaped box.

[0011] By adopting the above technical solution, bolts can be screwed between the ear plate and the mounting hole of the T-shaped box, thereby installing the side cover at the T-shaped box.

[0012] Furthermore, the diameter of the screw body is smaller than the diameter of the coils of springs A and B;

[0014] Furthermore, the shaft is fitted with a bearing inside the wire-transmitting wheel, and a bolt is screwed onto the shaft where it passes through the hole of the wire-transmitting wheel.

[0015] By adopting the above technical solution, after the wire conveying wheel is mounted on the outside of the shaft cylinder with a bearing to obtain rotational support, the bolt can be screwed into the cylinder hole of the shaft cylinder to prevent the wire conveying wheel from falling outward.

[0016] Furthermore, a gap larger than the thickness of the L-shaped lifting plate is reserved between the fixed plate and the fixed opening, and the vertical plate of the L-shaped lifting plate is inserted between the fixed plate and the fixed opening;

[0017] By adopting the above technical solution, the distance between the fixed plate and the fixed opening can be used for the vertical lifting of the L-shaped lifting plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model establishes a wire feeding mechanism for a computerized horizontal braiding machine by setting a wire adjustment mechanism at the wire feeder in the existing patented technology. The design of the wire adjustment mechanism allows the wire between the transmission wheels inside the wire feeder to elastically adjust the tension during feeding, thereby ensuring that the tension or position of the wire during feeding of the computerized horizontal braiding machine can be finely adjusted, and ensuring the quantitative feeding accuracy of the wire in the computerized horizontal braiding machine.

[0020] Furthermore, the L-shaped lifting plate of the wire adjustment mechanism obtains stable guidance during lifting through the cooperation of the guide groove and the guide plate. This helps to ensure the stability and accuracy of the steel wire during the conveying process. The mechanism can stably convey the steel wire and adjust the steel wire conveying tension as needed, thus helping to improve the weaving efficiency and quality of the computer flat braiding machine.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-3 As shown, a wire feeding mechanism for a computerized horizontal braiding machine includes a wire feeder 1 and a drive wheel 2. The drive wheel 2 is installed inside the wire feeder 1. The mechanism also includes a wire adjusting mechanism 3, which comprises a side mounting base 4, a T-shaped box 5, a fixed plate 7, a side cover 8, an L-shaped lifting plate 10, a shaft cylinder 11, a wire feeding wheel 12, a screw 14, spring A 15, spring B 16, and a flange nut 17. The side mounting base 4 is bolted to the surface of the wire feeder 1 above the drive wheel 2, and a T-shaped box 5 is welded between the side mounting bases 4, covering the drive wheel 2. Ear plates 9 are bolted to the outer sides of the two side walls of the T-shaped box 5, and a side cover 8 is welded between the ear plates 9 to cover the side opening of the T-shaped box 5. The T-shaped box 5 is positioned against... The top of the box body near the side cover 8 is provided with a fixed opening 6 for inserting the fixed plate 7 and the L-shaped lifting plate 10. The fixed plate 7 is integrally formed on the cover surface of the side cover 8. The L-shaped lifting plate 10 extends into the vertical plate of the T-shaped box 5 and is welded with a shaft cylinder 11. A wire-carrying wheel 12 is installed outside the cylinder of the shaft cylinder 11. The L-shaped lifting plate 10 extends out of the top flat plate of the T-shaped box 5 and is provided with a guide hole 13 for inserting a screw 14. The screw 14 is welded to the top of the box body of the T-shaped box 5. A spring A15 is sleeved on the screw 14 below the L-shaped lifting plate 10, and a spring B16 is sleeved on the upper rod of the screw 14 extending out of the L-shaped lifting plate 10. A flange nut 17 is screwed onto the screw 14 above the spring B16.

[0027] Among them, the top of the L-shaped lifting plate 10 on one side of the guide hole 13 is provided with a guide groove 19 for mounting the guide plate 18, and the guide plate 18 is welded to the top of the T-shaped box 5 below the L-shaped lifting plate 10.

[0028] By adopting the above technical solution, the L-shaped lifting plate 10 is clamped at the guide plate 18 above the T-shaped box 5 with the guide groove 19 to obtain guidance during lifting.

[0029] The ear plate 9 and the box wall of the T-shaped box 5 are symmetrically provided with mounting holes, and bolts are screwed between the ear plate 9 and the mounting holes of the T-shaped box 5.

[0030] By adopting the above technical solution, bolts can be screwed between the ear plate 9 and the mounting hole of the T-shaped box 5, so that the side cover 8 can be installed at the T-shaped box 5.

[0031] Wherein, the diameter of the screw 14 is smaller than the diameter of the spring coils of spring A15 and spring B16;

[0032] By adopting the above technical solution, springs A15 and B16 can smoothly bounce on the outside of screw 14.

[0033] The shaft cylinder 11 is fitted with a bearing inside the wire transmission wheel 12, and a bolt is screwed onto the shaft cylinder 11 at the point where it passes through the cylinder hole of the wire transmission wheel 12.

[0034] By adopting the above technical solution, after the wire conveying wheel 12 is mounted on the outside of the shaft cylinder 11 with a bearing to obtain rotational support, the bolt can be screwed into the cylinder hole of the shaft cylinder 11 to prevent the wire conveying wheel 12 from falling outward.

[0035] The fixed plate 7 and the fixed opening 6 have a gap greater than the thickness of the L-shaped lifting plate 10, and the vertical plate of the L-shaped lifting plate 10 is inserted between the fixed plate 7 and the fixed opening 6.

[0036] By adopting the above technical solution, the distance between the fixed plate 7 and the fixed opening 6 can allow the L-shaped lifting plate 10 to be vertically raised and lowered.

[0037] It should be noted that this utility model is a wire conveying mechanism for a computerized horizontal braiding machine. It incorporates a wire adjusting mechanism 3 at the existing wire feeder 1, forming the wire conveying mechanism for the computerized horizontal braiding machine. The T-shaped box 5 of the wire adjusting mechanism 3 is secured above the wire feeder 1 with a side mounting base 4 and bolts. A spring A15 is clamped at the screw 14 above the T-shaped box 5. Then, an L-shaped lifting plate 10 is guided and installed at the screw 14 and the guide plate 18 above the T-shaped box 5 using guide holes 13 and guide grooves 19. After clamping a spring B16 at the screw 14 above the L-shaped lifting plate 10, a flange nut 17 is screwed on. Next, the vertical plate of the L-shaped lifting plate 10 is inserted downwards into the T-shaped box 5 from the fixed opening 6. The wire conveying wheel 12 can be installed at the shaft cylinder 11 of the L-shaped lifting plate 10 for support during rotation, while the side cover 8 blocks the T-shaped box. After the side box opening of 5 is removed, the fixed plate 7 of the side cover 8 can be inserted into the fixed opening 6. At this time, the ear plate 9 of the side cover 8 is locked to the outside of the T-shaped box 5 with bolts. After the side cover 8 is removed, the steel wire can be introduced from the feeding slot of the wire feeder 1. After the steel wire passes around one set of wheels of the transmission wheel 2, it can continue to wind upward into the groove of the transmission wheel 12. Then the steel wire can continue to pass around another set of wheels of the transmission wheel 2 and then be led out from the feeding slot on the other side of the wire feeder 1 for steel wire transportation. Then the side cover 8 can be reinstalled. When the steel wire between the transmission wheels 2 is transported at the transmission wheel 12, the transmission wheel 12 obtains upper and lower elastic support at the screw 14 with the L-shaped lifting plate 10, thereby ensuring that the steel wire between the transmission wheel 12 and the transmission wheel 2 is elastically tightened, and the tension is increased when the steel wire is transported.
