[0002] A textile machine, also known as a cotton spinning machine or a loom, can weave cloth by pulling the silk threads on multiple yarn wheels separately. However, during the weaving process, multiple textile threads need to be pulled separately to avoid entanglement between them, which would affect the use of the weaving. Therefore, a textile thread positioning device is required.

[0003] In the prior art, such as a textile thread positioning device with patent number CN113265749B, a sticky plate is used to quickly find the thread end, and a filter ball is used to clean the hair on the textile thread, thereby improving the efficiency and effect of the textile thread output. However, in order to improve the compactness of the spinning wheel during the winding process, the spinning wheel will reciprocate the thread, resulting in the textile thread also extending along the axial reciprocating motion of the spinning wheel during the traction process. In the prior art, the textile thread is pulled by gears, which causes vibrations during the reciprocating motion of the textile thread, making it impossible to achieve smooth thread guiding, especially during the weaving process, the textile thread is positioned through the thread guide hole to make the textile thread straight, which is more likely to cause the textile thread to break under the influence of vibration.

In the present technical solution, the position of the positioning frame is also adjusted by setting a driving member. That is, when the positioning table is raised to a higher height, the angle between the textile line and the horizontal line between the positioning table and the positioning seat is too large, which will increase the contact friction between the positioning seat and the guide wheel and the textile line. Therefore, the positioning frame is controlled by the driving member to move in a direction away from the positioning table, thereby reducing the angle between the textile line and the horizontal, thereby reducing the damage to the textile line structure due to frictional force.

DETAILED DESCRIPTION

[0038] 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.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1-Figure 9 The present invention provides a textile thread positioning device for textile fabric production, comprising:

[0041] The base 1 is provided with a wire roller 2 and a positioning platform 3 on opposite sides of the top surface. The wire roller 2 is used to fix the spinning wheel 4. The positioning platform 3 is capable of vertical lifting. The top surface of the positioning platform 3 is successively provided with guide wheels 5 and positioning plates 6 in the direction close to the textile machine. The positioning plate 6 is provided with a lead-in hole. The textile wire can slide in contact with the guide wheel 5 and pass through the lead-in hole in the horizontal direction. Thus, the textile wire is positioned through the lead-in hole, so that the textile wire passing through the lead-in hole can be directly connected to the textile machine to make up the wire during the textile process.

[0042] The positioning assembly includes a positioning frame 7 arranged between the line roller 2 and the positioning platform 3. A driving member is arranged on the base 1. The driving end of the driving member is connected to the positioning frame 7 so that the positioning frame 7 can move between the line roller 2 and the positioning platform 3. A positioning seat 8 is vertically slidably connected inside the positioning frame 7, and the positioning seat 8 is connected to the positioning frame 7 through a vibration-damping buffer portion. A positioning hole running through both sides is opened on the positioning seat 8, and the textile line is passed through the positioning hole.

[0043] The present invention sets a positioning frame 7 between the line roller 2 and the positioning platform 3, and uses a vibration reduction buffer part to elastically slide a positioning seat 8 on the positioning frame 7, so as to position the textile line through the positioning hole of the positioning seat 8, and limit the textile line during the weaving process of the textile machine. When the textile line reciprocates and extends out of the spinning wheel 4, the positioning seat 8 absorbs the vibration influence on the textile line through the vibration reduction buffer part, effectively reduces the vibration and stabilizes the textile line, so that the textile line is smoothly extended, and the tensioned textile line is reduced from being broken due to the vibration influence caused by the movement amplitude, thereby improving the positioning effect. In addition, the positioning platform 3 is raised and lowered relative to the base 1, so that the textile line horizontally passing through the lead hole can correspond to the feed line height of the textile machine, which is convenient for weaving, and the guide wheel 5 is used to control the pull-out position of the textile line. On the basis of the ability of the present patent to adjust the positioning height of the textile line, the textile line can be kept in a horizontal state and extend out of the lead hole at different heights.

[0044] In addition, since the positioning platform 3 has an adjustable height, and the textile line slides in contact with the guide wheel 5 after passing through the positioning hole, there is a variable angle between the textile line between the positioning platform 3 and the positioning seat 8. In the present technical solution, the position of the positioning frame 7 is also adjusted by setting a driving member. That is, when the positioning platform 3 is raised to a higher height, the angle between the textile line and the horizontal line between the positioning platform 3 and the positioning seat 8 is too large, which will cause the contact friction between the positioning seat 8 and the guide wheel 5 and the textile line to increase. Therefore, the positioning frame 7 is controlled by the driving member to move in a direction away from the positioning platform 3, thereby reducing the angle between the textile line and the horizontal, thereby reducing the damage to the textile line structure caused by frictional force.

[0045] In one embodiment of the present invention, the line roller 2 is rotatably connected to the base 1 through a bearing, and a plurality of arc-shaped spring pieces 9 are fixedly connected to the outer peripheral side of the line roller 2. When the spinning wheel 4 is sleeved on the line roller 2, the raised portion of the arc-shaped spring piece 9 abuts against the inner ring side of the spinning wheel 4, thereby effectively fixing the spinning wheel 4 and the line roller 2, and during the weaving process of the textile machine, the spinning wheel 4 can be pulled and drawn along the direction of the lead hole.

[0046] Furthermore, a first slide groove is opened in the positioning frame 7 along the vertical direction, and the positioning seat 8 is slidably connected in the first slide groove along the axial limit, and the vibration damping and buffering part includes a pair of vibration damping springs 10 fixedly connected to both sides of the positioning seat 8, and the two ends of the vibration damping spring 10 are respectively fixedly connected to the inner wall surface of the first slide groove and the positioning seat 8.

[0047] A pair of damping springs 10 are symmetrically arranged along the center of the positioning seat 8, and the damping springs 10 are used to dampen the vibration of the positioning seat 8, thereby achieving damping of the vibration of the textile thread running through the positioning hole.

[0048] Specifically, by arranging the positioning seat 8 centrally in the first slide groove, using a shock-absorbing spring 10 with the same elasticity and length, respectively fixing the shock-absorbing spring 10 to the top surface and the bottom end of the positioning seat 8, and winding the shock-absorbing spring 10 around the damping piston rod 11, and respectively fixing the two ends of the damping piston rod 11 to the positioning seat 8 and the adjacent first slide groove inner wall surface, the support and vibration reduction of the positioning seat 8 is achieved.

[0049] The positioning seat 8 adopts a convex structure. By fixing a limiting rod 12 on one side of the inner wall of the first slide groove, and opening a limiting groove on the side of the positioning seat 8 away from the protruding end, the limiting rod 12 is slidably connected with the limiting groove, so that the positioning seat 8 is limitedly slidably connected with the first slide groove, thereby improving the sliding stability of the positioning seat 8.

[0050] Furthermore, two first slide grooves are symmetrically provided along the center of the positioning frame 7 , and positioning platforms 3 and line rollers 2 are respectively provided on both sides of the two first slide grooves, and the two positioning platforms 3 and line rollers 2 are symmetrical along the center width direction of the base 1 .

[0051] In the actual weaving process, multiple groups of textile threads are usually used. In order to avoid entanglement between adjacent textile threads, two first slide grooves are opened symmetrically along the center of the positioning frame 7, and two positioning platforms 3 and wire rollers 2 are arranged correspondingly on the same base 1. One wire roller 2, one first slide groove and one positioning platform 3 are used to position one textile thread, thereby improving the separation and positioning effect of the textile threads, and by setting multiple side-by-side bases 1, the positioning of multiple textile threads can be achieved.

[0052] Furthermore, the positioning hole is formed by connecting two tapered holes that are relatively distributed, the middle of the positioning hole is the end with the smallest diameter, and the connecting ends of the two tapered holes have a smooth transition.

[0053] In order to improve the positioning efficiency of the textile thread, the two sides of the positioning hole are set to a conical structure to facilitate the passage of the textile thread through the positioning hole. In the process of smoothing the connecting end of the conical hole, the contact friction of the positioning seat 8 on the textile thread is reduced to avoid the positioning seat 8 causing friction to the textile thread and affecting the use of the textile thread.

[0054] Furthermore, the driving member includes:

[0055] The first drive motor 13 is fixedly connected to the base 1. A movable groove is opened on the top surface of the base 1 along the length direction. A movable seat 15 is limitedly slidably connected in the movable groove. The top end of the movable seat 15 extends out of the movable groove and is fixedly connected to a mounting plate 16. The bottom end of the positioning frame 7 is fixedly connected to the mounting plate 16; the first screw 14 is transferred into the movable groove. The output shaft of the first drive motor 13 is coaxially fixedly connected to the first screw 14, and the movable seat 15 is threadedly sleeved on the first screw 14.

[0056] The first driving motor 13 is used to rotate the first screw rod 14 , and the rotation of the first screw rod 14 causes the moving seat 15 threadedly sleeved on the first screw rod 14 to slide along the moving groove, and the moving seat 15 is used to realize the movement and adjustment of the mounting plate 16 and the positioning frame 7 .

[0057] Furthermore, a pair of guide wheels 5 are provided, and the mutually adjacent sides of the pair of guide wheels 5 are in vertical rolling contact to define a guide channel along the length direction of the positioning platform 3, and a receiving box 17 is fixedly connected to one side of the top surface of the positioning platform 3 close to the guide wheel 5, and support plates 18 are fixedly connected to both sides of the top of the receiving box 17, respectively. The two ends of the pair of guide wheels 5 are respectively connected to the two support plates 18 through a damping shaft 19; wherein, the bottom of the guide wheel 5 located at the bottom extends into the receiving box 17, and the receiving box 17 is used to contain silicone oil.

[0058] In the present technical solution, the traction state of the textile line is adjusted by the guide wheel 5. It can be understood that a guide groove is opened in the center of the guide wheel 5. A pair of guide wheels 5 are relatively arranged so that the contact ends of the two guide grooves are buckled to define a guide channel. When the textile line passes through the guide channel, no matter whether the height of the positioning platform 3 is higher or lower than the positioning seat 8, the textile line can slide in contact with the guide wheel 5 to achieve positioning and guiding of the textile line.

[0059] Furthermore, by fixing the accommodating box 17 to the bottom end of the lowest guide wheel 5, during the process of the textile machine pulling the textile thread, due to the sliding contact between the textile thread and the guide wheel 5, when the contact friction between the two is too large, the textile thread can drive the guide wheel 5 to rotate, thereby rotating and extending the part immersed in the accommodating box 17, so that the textile thread is lubricated with silicone oil, and the pair of guide wheels 5 are in rolling contact with each other, so that the silicone oil penetrates into each other between the pair of guide wheels 5, thereby enhancing the use effect of the textile thread and reducing the possibility of thread breakage.

[0060] Furthermore, the positioning plate 6 is provided with a through groove penetrating the wire hole in the vertical direction, and a clamp 20 is slidably fitted in the through groove, and the clamp 20 can block the wire hole. A transmission assembly is provided on the positioning platform 3, and the transmission assembly is used to connect the textile line and the clamp 20 to make the textile line taut and lift the clamp 20 vertically upward.

[0061] The splint 20 is slidably connected in the through groove, and the splint 20 can block the lead-in hole. The textile line is tightened by the transmission component and the splint 20 is lifted. Once the line breaks during the weaving process, the textile line loses the tightening force at the first time, and the transmission component also loses the lifting effect on the splint 20. The splint 20 slides down to block the lead-in hole and clamp the broken line, thereby facilitating the staff to find the thread ends of the textile line and repeatedly pass the line into the textile machine for weaving operations, thereby improving work efficiency.

[0062] Furthermore, the transmission assembly includes:

[0063] The transmission plate 21 and the top surface of the positioning platform 3 are provided with a transfer groove on one side away from the guide wheel 5, in which a rotating rod 22 is transferred, and a torsion spring 23 is wound around both ends of the rotating rod 22, and both ends of the torsion spring 23 are respectively fixed to the rotating rod 22 and the positioning platform 3, and the bottom end of the transmission plate 21 is fixed to the side wall of the rotating rod 22, and the top end of the transmission plate 21 is tilted upward to abut against the textile line; a pair of transmission gears 24 are respectively transferred to the positioning platform 3, and a pair of transmission gears 24 are meshed with the same tooth plate 25, and the tooth plate 25 is slidably connected to the positioning platform 3, one of the pair of transmission gears 24 is sleeved and fixedly connected to the rotating rod 22, and the axis of the other is fixedly connected to a transmission rod 26, and a driven gear 27 is sleeved and fixedly connected to the transmission rod 26, and a rack 28 is meshed on one side of the driven gear 27, and the top end of the rack 28 extends vertically out of the positioning platform 3 and is fixedly connected to the clamping plate 20.

[0064] Specifically, a card plate 29 is fixed to the top of the transmission plate 21, and an arc-shaped card slot is opened on the card plate 29. The textile line is placed in the card slot, and the positioning platform 3 is raised and lowered to make the textile line extend out of the positioning platform 3 in a horizontal or inclined downward direction, so that the textile line forms an extrusion effect on the transmission plate 21, and is transmitted to the torsion spring 23 through the rotating rod 22, forming elastic compression, tightening the textile line, and serving as a starting force for triggering the splint 20 when the line is broken.

[0065] When the textile thread breaks, the transmission plate 21 flips toward the positioning plate 6 and drives the rotating rod 22 to rotate the transmission gear 24. The transmission gear 24 is transmitted through the same tooth plate 25 to rotate the other transmission gear 24, thereby rotating the transmission rod 26. The transmission rod 26 drives the driven gear 27 to rotate, so that the meshing rack 28 moves the clamping plate 20 downward, thereby controlling the clamping plate 20 to clamp the bottom end of the lead hole towards each other, and the broken textile thread is positioned and fixed, which is convenient for personnel to find the thread end and reinstall it on the textile machine.

[0066] Furthermore, the distance between the bottom surface of the clamping plate 20 and the inner wall of the bottom end of the lead hole is smaller than the length of the rack 28 extending out of the positioning platform 3 .

[0067] By opening an empty groove in the positioning platform 3, the rack 28 can slide vertically, and when the driven gear 27 is engaged with the rack 28, the rack 28 can move the clamp 20 to clamp the broken textile thread. The relationship between the length of the rack 28 extending out of the positioning platform 3 and the distance between the bottom surface of the clamp 20 and the inner wall of the bottom end of the lead hole can ensure that the rack 28 drives the clamp 20 to abut against the inner wall of the bottom end of the lead hole for clamping.

[0068] Furthermore, it also includes:

[0069] The lifting assembly includes a lifting platform 30 fixedly connected to the top surface of the base 1, a second slide groove is provided on one side of the lifting platform 30, a slider 31 is limitedly slidably connected in the second slide groove, a cylinder 32 is fixedly connected to the side of the slider 31 close to the positioning platform 3, and a piston end of the cylinder 32 is fixedly connected to the positioning platform 3;

[0070] The second drive motor 33 is fixedly connected to the top surface of the lifting platform 30 . The second screw 34 is connected in the second slide slot. The output shaft of the second drive motor 33 is coaxially fixedly connected to the second screw 34 . The slider 31 is threadedly sleeved on the second screw 34 .

[0071] The cylinder 32 is used to control the extension distance of the positioning platform 3 relative to the lifting platform 30, so that the guide wheel 5 is parallel to the positioning seat 8, and the second drive motor 33 rotates the second screw 34, so that the slider 31 threadedly mounted on the second screw 34 slides along the second slide groove, thereby adjusting the height of the positioning platform 3.

[0072] The working principle of the textile thread positioning device used in textile fabric production of the present invention is as follows:

[0073] The spinning wheel 4 is fixedly mounted on the line roller 2, and the thread end is stretched out, the textile thread is passed along the direction of the positioning hole, and the textile thread is inserted between a pair of guide wheels 5 and horizontally extended along the direction of the lead hole. The textile thread is placed on the clamping plate 29 to squeeze the transmission plate 21, and the positioning platform 3 is lifted to the same height as the textile machine through the second drive motor 33 and the second screw 34, and the textile operation is performed through the textile machine.

[0074] During the weaving process, the textile thread is pulled back and forth from the spinning wheel 4 and directly transmits the force to the positioning seat 8. The damping springs 10 at both ends of the positioning seat 8 perform vibration reduction and buffering on the positioning seat 8 and the textile thread, thereby increasing the service life of the textile thread. According to the lifting height of the positioning platform 3, the distance between the positioning frame 7 and the positioning platform 3 is adjusted by the first drive motor 13 and the first screw 14 to avoid excessive angle between the textile thread and the horizontal direction, thereby enhancing the protection effect on the textile thread. Two spinning wheels 4 can be relatively arranged on the base 1, and the textile threads are separated by two first slide grooves symmetrically along the center of the positioning frame 7. By arranging multiple bases 1 side by side, several textile threads can be introduced into the textile machine at intervals.
