Description

Technical Field

[0001] This invention relates to the field of heddle production technology, and in particular to an automatic yarn threading hole polishing machine. Background Technology

[0002] Heddle wires are a type of loom accessory, made of thread, steel wire, or steel sheet, and can also be made of plastic. They have small holes (heddle eyes) in the center through which warp yarns pass, and each heddle wire controls one warp yarn. During weaving, they move the warp yarns up and down to form the shed, facilitating the introduction of the weft yarn. Currently, after heddle wire production, polishing machines are often used to grind the thread holes to prevent burrs from forming on the edges, which could affect the passage of warp yarns or even cause breakage. However, existing polishing machines mostly only polish one side of the heddle wire, resulting in poor polishing of the thread holes and affecting the subsequent use of the heddle wire. Summary of the Invention

[0003] This invention proposes an automatic yarn threading hole polishing machine to solve the problem that existing polishing machines only polish one side of the heddle wire, resulting in poor polishing effect of the yarn threading hole.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic yarn threading hole polishing machine, comprising a feeding mechanism, an upper polishing component, a lower polishing component, and a receiving mechanism arranged sequentially along the heddle wire conveying direction, wherein two upper polishing components and two lower polishing components are provided, and the two upper polishing components and the two lower polishing components are arranged alternately. The upper polishing component is used to polish the top of the yarn threading hole on the heddle wire, and the lower polishing component is used to polish the bottom of the yarn threading hole on the heddle wire.

[0005] Preferably, the upper polishing assembly includes an upper polishing frame, with mounting brackets fixed on both sides of the top of the upper polishing frame, and an upper polishing roller is mounted on the bottom of both mounting brackets. A first motor for driving the upper polishing roller to rotate is fixed on the top of one of the mounting brackets.

[0006] Preferably, the lower polishing assembly includes a lower polishing frame, and a second motor and a lower polishing roller are installed inside the lower polishing frame. The second motor is located below the lower polishing roller and is used to drive the lower polishing roller to rotate.

[0007] Preferably, the upper polishing frame has a support plate installed inside, which is parallel to the lower polishing roller and directly below it. A gap is left between the bottom of the support plate and the bottom of the upper polishing roller for the heddle wire to move. The lower polishing frame has a fixing frame installed on top, and a limit plate is fixed at the bottom of the fixing frame. The limit plate is parallel to the upper polishing roller and directly above it. A gap is left between the bottom of the limit plate and the top of the lower polishing roller for the heddle wire to move.

[0008] Preferably, the feeding mechanism includes a feeding frame, on which a feeding roller and a feeding motor are mounted, and the feeding motor is used to drive the feeding roller to rotate.

[0009] Preferably, the receiving mechanism includes a receiving frame, on the side of the receiving frame away from the lower polishing frame a winding roller and a third motor are provided, and the third motor is used to drive the winding roller to rotate. On the side of the receiving frame close to the lower polishing frame a fourth motor, a pressure roller and two guide rollers are provided, and the pressure roller is located between the tops of the two guide rollers. The fourth motor is used to drive one of the guide rollers and the pressure roller to rotate synchronously.

[0010] Preferably, the receiving rack is further provided with an adjustment assembly for adjusting the height of the clamping roller, and the adjustment assembly includes two adjustment brackets mounted on the top of the receiving rack. Two adjustment screws are screwed onto each of the two adjustment brackets. Nuts are screwed onto the top of each adjustment screw, and a movable block is installed on two adjacent adjustment screws. The clamping roller is rotatably mounted between the two movable blocks.

[0011] Preferably, the top of the movable block is further provided with two recesses, and springs are connected between the two recesses and the adjusting bracket, with the springs sleeved on the outside of the adjusting screw.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: (1) The present invention uses two spaced upper polishing components and lower polishing components to alternately polish the top and bottom of the threading hole on the heddle wire, thereby achieving double-sided polishing of the heddle wire. This solves the problem that existing single-sided polishing easily leads to burrs on the edge of the threading hole, which in turn helps to improve the polishing effect of the threading hole on the heddle wire, improve the processing quality of the heddle wire, and facilitate the subsequent use of the heddle wire.

[0013] (2) On the one hand, the present invention provides a support plate, which can support the heddle wire during grinding to ensure stable contact between the heddle wire and the upper polishing roller, thus facilitating stable grinding of the heddle wire. On the other hand, it provides a limiting plate, which limits the heddle wire to the top of the lower polishing roller during grinding to ensure stable contact between the heddle wire and the lower polishing roller, thus facilitating stable grinding of the heddle wire, thereby achieving stable polishing of the heddle wire, which is beneficial to improving the polishing quality and efficiency of the heddle wire.

[0014] (3) The present invention, through the cooperation of the pressing roller and the guiding roller, can guide the heddle wire to provide power for the winding of the heddle wire, and can press the heddle wire to facilitate the stable winding of the heddle wire, thereby facilitating the efficient winding of the heddle wire. Furthermore, by adjusting the settings of the components, the height position of the pressure roller can be adjusted, thereby ensuring that the pressure roller presses the heddle wire against the guide roller, preventing slippage between the heddle wire and the guide roller, which is conducive to the stable and rapid winding of the heddle wire.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 like Figure 1As shown, the automatic yarn threading hole polishing machine includes a feeding mechanism 1, an upper polishing component 2, a lower polishing component 3, and a receiving mechanism 4 arranged sequentially along the heddle wire conveying direction. There are two upper polishing components 2 and two lower polishing components 3, and the two upper polishing components 2 and the two lower polishing components 3 are arranged alternately. The upper polishing component 2 is used to polish the top of the yarn threading hole on the heddle wire, and the lower polishing component 3 is used to polish the bottom of the yarn threading hole on the heddle wire.

[0019] In this invention: Regarding the aforementioned upper polishing component 2, as follows: Figure 3 As shown, the upper polishing assembly 2 includes an upper polishing frame 21. Mounting brackets 24 are fixed on both sides of the top of the upper polishing frame 21, and an upper polishing roller 22 is mounted on the bottom of both mounting brackets 24. A first motor 23 for driving the upper polishing roller 22 to rotate is fixed on the top of one of the mounting brackets 24.

[0020] Regarding the aforementioned lower polishing component 3, as follows: Figure 4 As shown, the lower polishing assembly 3 includes a lower polishing frame 31. A second motor 32 and a lower polishing roller 33 are installed inside the lower polishing frame 31. The second motor 32 is located below the lower polishing roller 33 and is used to drive the lower polishing roller 33 to rotate.

[0021] Regarding the aforementioned feeding mechanism 1, as follows: Figure 2 As shown, the feeding mechanism 1 includes a feeding frame 11, on which a feeding roller 12 and a feeding motor 13 are mounted, and the feeding motor 13 is used to drive the feeding roller 12 to rotate.

[0022] Regarding the aforementioned receiving mechanism 4, as follows: Figure 5 As shown, the receiving mechanism 4 includes a receiving frame 41. A take-up roller 42 and a third motor 46 are provided on the side of the receiving frame 41 away from the lower polishing frame 31. The third motor 46 is used to drive the take-up roller 42 to rotate. A fourth motor 47, a pressure roller 44 and two guide rollers 43 are provided on the side of the receiving frame 41 close to the lower polishing frame 31. The pressure roller 44 is located between the tops of the two guide rollers 43. The fourth motor 47 is used to drive one of the guide rollers 43 and the pressure roller 44 to rotate synchronously.

[0023] As described above, when polishing heddles, the heddles to be processed can be wound onto the feed roller 12, and one end of the heddles can be pulled and passed through the upper polishing assembly 2 and the lower polishing assembly 3 in sequence until they are wound onto the take-up roller 42. Then, the feed motor 13 drives the feed roller 12 to rotate to feed the heddles. At the same time, the third motor 46 drives the take-up roller 42 to rotate to take the heddles, and the fourth motor 47 drives the guide roller 43 and the pressure roller 44 to rotate to transport the heddles, so that the take-up roller 42 can take the heddles. During this process, the first motor 23 drives the upper polishing roller 22 to rotate, so that the upper polishing roller 22 polishes the top of the threading hole on the heddles. At the same time, the second motor 32 drives the lower polishing roller 33 to rotate, so that the lower polishing roller 33 polishes the bottom of the threading hole on the heddles, thereby completing the polishing process of the threading hole on the heddles. In summary, the present invention, through two spaced-apart upper polishing components 2 and lower polishing components 3, can alternately polish the top and bottom of the threading hole on the heddle wire, thereby achieving double-sided polishing of the heddle wire. This solves the problem that existing single-sided polishing easily leads to burrs on the edge of the threading hole, thus improving the polishing effect of the threading hole on the heddle wire, improving the processing quality of the heddle wire, and facilitating the subsequent use of the heddle wire.

[0024] Meanwhile, in this embodiment, such as Figure 3 and Figure 4 As shown, a support plate 25 is installed inside the upper polishing frame 21. The support plate 25 is parallel to the bottom of the upper polishing roller 22, and a gap is left between the bottom of the support plate 25 and the bottom of the upper polishing roller 22 for the heddle wire to move. A fixing frame 35 is installed on the top of the lower polishing frame 31, and a limiting plate 34 is fixed to the bottom of the fixing frame 35. The limiting plate 34 is parallel to the top of the lower polishing roller 33, and a gap is left between the bottom of the limiting plate 34 and the top of the lower polishing roller 33 for the heddle wire to move.

[0025] During the heddle polishing process, when the upper polishing roller 22 polishes the threading holes on the heddle, the support plate 25 can support the heddle to ensure stable contact between the heddle and the upper polishing roller 22, facilitating stable polishing of the heddle. When the lower polishing roller 33 polishes the threading holes on the heddle, the limiting plate 34 can limit the heddle to the top of the lower polishing roller 33 to ensure stable contact between the heddle and the lower polishing roller 33, facilitating stable polishing of the heddle. This achieves stable polishing of the heddle, which is beneficial to improving the polishing quality and efficiency of the heddle.

[0026] Example 2 Based on Example 1, such as Figure 5 and Figure 6As shown, the receiving rack 41 is also provided with an adjustment component 45 for adjusting the height of the pressing roller 44. The adjustment component 45 includes two adjustment brackets 451 mounted on the top of the receiving rack 41. Two adjustment screws 454 are screwed onto each of the two adjustment brackets 451. Nuts 455 are screwed onto the top of each adjustment screw 454. A movable block 452 is installed on two adjacent adjustment screws 454. The pressing roller 44 is rotatably mounted between the two movable blocks 452.

[0027] Furthermore, two recesses are provided on the top of the movable block 452, and springs 453 are connected between the two recesses and the adjusting bracket 451, with the springs 453 sleeved on the outside of the adjusting screw 454.

[0028] During the heddle winding process, the adjusting screw 454 can be rotated to drive the movable block 452 to rise or fall. Subsequently, the movable block 452 drives the pressure roller 44 to rise or fall. At this time, the spring 453 extends and retracts accordingly to ensure the stable raising and lowering of the movable block 452, thereby realizing the height adjustment of the pressure roller 44. This allows the pressure roller 44 to press the heddle wire against the guide roller 43, preventing slippage between the heddle wire and the guide roller 43, which is conducive to the stable and rapid winding of the heddle wire.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
