Description

Technical Field

[0001] This invention relates to the field of automatic warp threading technology, and in particular to a heddle stabilizing mechanism and an automatic warp threading device. Background Technology

[0002] In the textile process, it is necessary to accurately separate individual heddles from the stack and feed them at high speed into the lead-in system. When the textile equipment is working, a large number of heddles are first stacked in the heddle storage area, and then conveyed to the corresponding process position on the automatic warping machine for high-speed separation of individual heddles. Due to the long and thin shape of the heddles, they undergo significant oscillation and deformation during high-speed separation, resulting in an unstable state. To ensure that the individual heddles smoothly enter the transfer mechanism, the warping machine must wait for a period of time to allow the heddles to stop oscillating and stabilize. This process takes considerable time, reducing production efficiency. Therefore, there is an urgent need for an automatic warping device to increase warping speed and thus improve production efficiency. Summary of the Invention

[0003] Based on this, this application provides a heddle stabilizing mechanism that can effectively reduce the oscillation during high-speed separation of heddle wires, thereby increasing the threading speed and improving production efficiency.

[0004] A heddle stabilizing mechanism is applied to an automatic warp threading device. The automatic warp threading device includes a base, a heddle storage mechanism, a heddle separation mechanism, and a heddle moving mechanism. The heddle storage mechanism includes an upper guide rod and a lower guide rod disposed on the base and spaced apart along the height direction. The upper guide rod and the lower guide rod are respectively used to thread the two ends of the heddle. The heddle separation mechanism is disposed on the base and located between the upper guide rod and the lower guide rod. The heddle separation mechanism is used to separate multiple heddles stacked between the upper guide rod and the lower guide rod. The heald wires are separated into individual heald wires along a first direction; the heald wire moving mechanism includes an upper heald pusher, a lower heald pusher, an upper heald hook, and a lower heald hook disposed on the base; the upper heald pusher is located between the upper heald hook and the upper guide rod, the lower heald pusher is located between the lower heald hook and the lower guide rod, the upper heald pusher is used to fasten one end of the heald wire from the upper guide rod into the upper heald hook, and the lower heald pusher is used to fasten the heald wire from the heald wire separating mechanism into the lower heald hook; characterized in that...

[0005] The heald stabilizing mechanism includes a base plate, a guide plate, and a damping plate located between the upper heald and the lower heald. The base plate is disposed on the base, the guide plate is disposed on the base plate, and the damping plate is elastically connected to the guide plate so as to extend and retract into the edge of the guide plate relative to each other along a second direction. The heald passes through and abuts against the damping plate during the process of moving from the upper guide rod and the lower guide rod to the upper heald hook and the lower heald hook. The second direction is perpendicular to the height direction and the first direction.

[0006] The above-mentioned heddle stabilizing mechanism can adjust the blocking force of the damping plate to accommodate different types of heddles. During automatic threading, the heddle separation mechanism separates individual heddles from the stack. Under the action of the heddle moving mechanism, the lower part of the individual heddle moves at high speed along the lower guide rod to the lower heddle assembly. During this movement, the individual heddle contacts the damping plate, squeezing the damping plate into the guide plate. This process significantly consumes the oscillation energy of the individual heddle, reducing its swing amplitude. After the individual heddle disengages from the damping plate, the damping plate resets, further preventing the individual heddle from swinging back. This effectively reduces the oscillation during high-speed heddle separation, thereby increasing threading speed and improving production efficiency.

[0007] In one embodiment, the width of the damping plate extending beyond the guide plate gradually increases along the first direction.

[0008] In one embodiment, the damping plate protrudes from the guide plate along the first direction.

[0009] In one embodiment, the damping plate is rotatably connected to the guide plate, and an elastic element is provided between the guide plate and the damping plate. The guide plate has multiple stop holes. One end of the elastic element is fixed to one of the stop holes, and the other end is fixed to the damping plate. The elastic force exerted on the damping plate by the elastic element fixed to different stop holes is different.

[0010] An automatic threading device includes the aforementioned heddle stabilizing mechanism, wherein a heddle guide channel is provided between the lower threading rod and the lower heddle pusher, and the damping plate is located directly above the heddle guide channel.

[0011] In one embodiment, the width of the guide plate at the opposite edges where the damping plate is located gradually increases along the first direction.

[0012] In one embodiment, the base plate has a strip groove extending along the second direction, and the guide plate is movably fixed to the strip groove by fasteners.

[0013] In one embodiment, the base is provided with two heddle wire storage mechanisms and a heddle wire moving mechanism spaced apart in the second direction, and the guide plate is provided with a damping plate on each of the opposite sides in the second direction.

[0014] In one embodiment, the heald wire moving mechanism includes an upper moving member and a lower moving member. The upper moving member is located between the upper heald hook and the upper heald post, and is used to push the heald wire from the upper heald post to the upper heald hook. The lower moving member is located between the lower heald hook and the lower heald post, and is used to push the heald wire from the lower heald post to the lower heald hook.

[0015] In one embodiment, the rotation axis of the upper heddle is parallel to the first direction, and the rotation axis of the lower heddle is parallel to the height direction. Attached Figure Description

[0029] A warp threading machine is a textile device primarily used to thread warp yarns through heddle holes and reed teeth, temporarily and locally fixing the warp yarns in terms of arrangement order, width, and density. Its function is to mechanically thread warp yarns into heddle holes and reed teeth according to a specific arrangement, ensuring the stability and accuracy of the warp yarns during the weaving process. Warp threading machines, through automation or semi-automation, reduce labor intensity, improve production efficiency, and guarantee the quality of warp threading. In the textile process, single heddle yarns need to be accurately separated from the stacked queue and fed at high speed into the lead-in system. When the textile equipment is working, a large number of heddle yarns are first stacked in the heddle yarn storage area, and then conveyed to the corresponding process position on the automatic warp threading machine for high-speed separation of single heddle yarns. Due to the long and thin shape of the heddle yarns, they undergo significant oscillation and deformation during high-speed separation, resulting in an unstable state of heddle yarn oscillation. To ensure that the single heddle yarns smoothly enter the transfer mechanism, the warp threading machine must wait for a period of time to allow the heddle yarns to stop oscillating and reach a stable state. This process takes a considerable amount of time, reducing production efficiency. Therefore, there is an urgent need for an automatic warp-threading device to increase warp-threading speed and thus improve production efficiency.

[0030] See Figures 1 to 7 To address the aforementioned problems, this application provides a heddle stabilizing mechanism 60, applied to an automatic warping device 10. The automatic warping device 10 includes a base 20, a heddle storage mechanism 30, a heddle separation mechanism 40, a heddle moving mechanism 50, and a heddle stabilizing mechanism 60. The heddle storage mechanism 30 includes an upper guide rod 31 and a lower guide rod 32 disposed on the base 20 and spaced apart along the height direction. The upper guide rod 31 and the lower guide rod 32 are respectively used to insert the two ends of the heddle 11. The heddle separation mechanism 40 is disposed on the base 20 and located between the upper guide rod 31 and the lower guide rod 32. The heddle separation mechanism 40 is used to separate multiple heddle 11 stacked between the upper guide rod 31 and the lower guide rod 32 into individual heddle 11 along a first direction P1. The heddle moving mechanism 50 includes an upper heddle pusher 51, a lower heddle pusher 52, an upper heddle hook 53, and a lower heddle hook 54 disposed on the base 20. The upper heddle-shifting component 51 is located between the upper heddle hook 53 and the string rod, and the lower heddle-shifting component 52 is located between the lower heddle hook 54 and the lower string rod 32. The upper heddle-shifting component 51 is used to fasten one end of the heddle wire 11 located on the upper string rod 31 to the upper heddle hook 53, and the lower heddle-shifting component 52 is used to fasten one end of the heddle wire 11 located on the lower string rod 32 to the lower heddle hook 54. The heddle wire stabilizing mechanism 60 includes a base plate 6 located between the upper heddle-shifting component 51 and the lower heddle-shifting component 52. 1. Guide plate 62 and damping plate 63, base plate 61 is provided on base 20, guide plate 62 is provided on base plate 61, damping plate 63 is elastically connected to guide plate 62, so as to extend and retract into the edge of guide plate 62 relative to each other along the second direction P2. During the process of moving from upper thread rod 31 and lower thread rod 32 to upper hanging hook 53 and lower hanging hook 54, the heddle wire 11 presses against damping plate 63. The second direction P2 is perpendicular to the height direction and the first direction P1.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the automatic threading device 10 includes a base 20, a heddle wire storage mechanism 30, a heddle wire separation mechanism 40, and a heddle wire moving mechanism 50. The heddle wire storage mechanism 30 is disposed on the base 20. The heddle wire storage mechanism has a number of heddle wires 11 to be fed. Specifically, the heddle wire storage mechanism includes an upper guide rod 31 and a lower guide rod 32, which are spaced apart along the height direction. In some embodiments, the upper guide rod 31 and the lower guide rod 32 are arranged in parallel. The heddle wire 11 has through holes at both ends. The upper guide rod 31 and the lower guide rod 32 pass through these through holes. For example, the upper guide rod 31 passes through the first through hole of multiple heddle wires 11, and the lower guide rod 32 passes through the second through hole of multiple heddle wires 11. This allows the multiple heddle wires 11 to be placed parallel to each other in the heddle wire storage mechanism, stacked on the upper guide rod 31 and the lower guide rod 32, so that the heddle wire separation mechanism 40 can separate the multiple heddle wires 11 in the next process. In some embodiments, the first and second through holes are U-shaped slots. A heddle wire separation mechanism 40 is located on the base 20. This mechanism separates individual heddle wires 11 from the heddle wire storage mechanism 30. Specifically, the heddle wire separation mechanism 40 is located between the upper guide rod 31 and the lower guide rod 32. It separates multiple heddle wires 11 stacked between the upper guide rod 31 and the lower guide rod 32 into individual heddle wires 11 along a first direction P1. A heddle wire moving mechanism 50 is located on the base 20. This mechanism transfers the heddle wires 11 to the warping station. Specifically, the heddle wire moving mechanism 50 includes an upper heddle pusher 51, a lower heddle pusher 52, an upper heddle hook 53, and a lower heddle hook 54. The upper and lower heddle hooks 53 and 54 fix and adjust the heddle wires 11, ensuring the production efficiency of the automatic warping equipment 10. The upper heddle-shifting component 51 is located between the upper heddle hook 53 and the upper guide rod 31, and the lower heddle-shifting component 52 is located between the lower heddle hook 54 and the lower guide rod 32. The upper heddle-shifting component 51 is used to fasten one end of the heddle wire 11 located on the upper guide rod 31 onto the upper heddle hook 53, and the lower heddle-shifting component 52 is used to fasten one end of the heddle wire 11 located on the lower guide rod 32 onto the lower heddle hook 54. The upper heddle-shifting component 51 and the lower heddle-shifting component 52 can respectively fasten both ends of the same heddle wire 11 onto the upper heddle hook 53 and the lower heddle hook 54. In some embodiments, the rotation axis of the upper heddle-shifting component 51 is parallel to the first direction P1, and the rotation axis of the lower heddle-shifting component 52 is parallel to the second direction P2, so that the separated heddle wire 11 can be smoothly fastened onto the upper heddle hook 53 and the lower heddle hook 54. In some embodiments, the base 20 is provided with two heddle wire storage mechanisms and heddle wire moving mechanisms 50 at intervals in the second direction P2, and the guide plate 62 is provided with a damping plate 63 on each of the opposite sides in the second direction P2. The two sets of heddle wire storage mechanisms and heddle wire moving mechanisms 50 can simultaneously perform processes such as separating and moving the heddle wires 11 on both sides, which can improve the working efficiency of the automatic threading equipment 10.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the heddle stabilizing mechanism 60 includes a base plate 61, a guide plate 62, and a damping plate 63 located between the upper heddle post 51 and the lower heddle post 52. The heddle stabilizing mechanism 60 can adjust the blocking force of the damping plate 63 to accommodate different types of heddles 11. When the automatic threading device 10 is working, the heddle separating mechanism 40 can separate a single heddle 11 from the stacked state. Under the action of the heddle moving mechanism 50, the lower part of the single heddle 11 moves at high speed along the lower threading rod 32 into the lower heddle post 52. During the movement, the single heddle 11 contacts the damping plate 63 and squeezes the damping plate 63 into the guide plate 62. This process will greatly consume the oscillation energy of the single heddle 11, reducing the amplitude of the swing of the single heddle 11. After the single heddle 11 disengages from the damping plate 63, the damping plate 63 resets, further preventing the single heddle 11 from swinging back. Without the heddle stabilizing mechanism 60, the single heddle wire 11 would oscillate significantly, potentially swinging outside the upper heddle-pulling component 51. In such cases, it would be necessary to wait for the lower moving component to move before pushing the lower heddle wire 11 into the lower heddle hook 54, and then wait for the lower heddle hook 54 to tighten the heddle wire 11 before the upper heddle-pulling mechanism can be activated. This sequence of actions takes longer, reducing production efficiency. Therefore, the heddle stabilizing mechanism 60 avoids the need to wait for the heddle wire 11 to stop oscillating and reach a stable state, effectively reducing the oscillation during high-speed separation of the heddle wire 11, thereby increasing the threading speed and improving production efficiency. Specifically, the base plate 61 of the heddle stabilizing mechanism 60 is located on the base 20, and the guide plate 62 is located on the base plate 61. The guide plate 62 can guide the movement of the heddle wire 11. The damping plate 63 is elastically connected to the guide plate 62. The damping plate 63 can move relative to the guide plate 62, that is, it can extend and retract relative to the edge of the guide plate 62 along the second direction P2. During the process of the heddle wire 11 moving from the upper guide rod 31 and the lower guide rod 32 to the upper hanging heddle hook 53 and the lower hanging heddle hook 54, it presses against the damping plate 63. The second direction P2 is perpendicular to the height direction and the first direction P1.

[0033] See Figure 3 , Figure 5 , Figure 6 and Figure 7In some embodiments, the width of the damping plate 63 extending from the guide plate 62 gradually increases along the first direction P1, allowing the heddle wire 11 to more smoothly press against and slide past the damping plate 63. The damping plate 63 protrudes from the guide plate 62 along the first direction P1; this protruding structure helps to limit the heddle wire 11 from rebounding to the side of the damping plate 63, more effectively limiting the position of the heddle wire 11 after passing the damping plate 63. The width of the guide plate 62 at its two opposite edges where the damping plate 63 is located gradually increases along the first direction P1. The middle portion of the heddle wire 11 advances along the guide plate 62, squeezing the damping plate 63 into the guide plate 62. After the heddle wire 11 reaches its position, the damping plate 63 springs back.

[0034] See Figure 3 , Figure 5 , Figure 6 and Figure 7In some embodiments, the damping plate 63 is rotatably connected to the guide plate 62, and an elastic element 64 is provided between the guide plate 62 and the damping plate 63, so that the damping plate 63 can extend and retract relatively flexibly relative to the guide plate 62. In the initial position, the damping plate 63 is in the extended state. When the vibrating heddle wire 11 is separated from the heddle wire separating mechanism 40 and passes through the heddle wire stabilizing mechanism 60, the damping plate 63 will be in the retracted state. The guide plate 62 has multiple stop holes 621, which can be used to adjust the blocking force of the damping plate 63 to accommodate different types of heddles 11. Specifically, one end of the elastic element 64 is fixed to one of the stop holes 621, and the other end is fixed to the damping plate 63. The elastic force of the elastic element 64 fixed to different stop holes 621 on the damping plate 63 is different, giving the heddle stabilizing mechanism 60 an adjustable function. The blocking force of the heddle stabilizing mechanism 60 can be adjusted according to the type of heddles 11, improving the practicality and convenience of the heddle stabilizing mechanism 60. For example, three types of stop holes 621 can be set according to the commonly used types of heddles 11, with different stop holes 621 spaced apart. In some embodiments, the elastic element 64 can be a damping spring, which is an elastic element between the equipment and the support structure, and is made of a helical steel spring that has been damped. Damping springs reduce the vibration or impact force transmitted from heddle wire 11 to damping plate 63 or from damping plate 63 to heddle wire 11. The working principle of a damping spring is to dissipate kinetic energy by providing resistance to motion. It possesses the dual advantages of low frequency and high damping of steel spring dampers, eliminating the inherent resonance amplitude phenomenon of steel springs. In some embodiments, the base plate 61 has a strip groove 611 extending along the second direction P2. The guide plate 62 is movably fixed to the strip groove 611 by fasteners 612. The cooperation of the strip groove 611 and the fasteners 612 allows the base plate 61 to accommodate heddle wires 11 of different lengths, sizes, and types, ensuring that the heddle wire 11 always contacts the heddle wire stabilizing mechanism 60 when passing through it. Installing the heddle wire stabilizing mechanism 60 on the automatic threading machine 10 optimizes the timing of actions by adjusting the operation of the automatic threading machine 10, greatly improving the threading speed and increasing production efficiency.

[0035] See Figure 3 , Figure 5 , Figure 6 and Figure 7In some embodiments, a heddle wire guide channel 70 is provided between the lower guide rod 32 and the lower heddle member 52, and the damping plate 63 is located directly above the heddle wire guide channel 70. The heddle wire guide channel 70 can provide guidance for the movement of the separated heddle wires 11. In some embodiments, the heddle wire moving mechanism 50 includes an upper moving member 55 and a lower moving member. The upper moving member 55 is disposed between the upper hanging heddle hook 53 and the upper heddle pusher 51. The upper moving member 55 is used to push the heddle wire 11 from the upper heddle pusher 51 to the upper hanging heddle hook 53. The upper moving member 55 can adopt a rotating shaft structure. The rotation of the rotating shaft drives the heddle wire 11 to move in a specified direction, thereby pushing the heddle wire 11 to the upper hanging heddle hook 53. The lower moving member is disposed between the lower hanging heddle hook 54 and the lower heddle pusher 52. The lower moving member is used to push the heddle wire 11 from the lower heddle pusher 52 to the lower hanging heddle hook 54. The rotation of the rotating shaft drives the heddle wire 11 to move in a specified direction, thereby pushing the heddle wire 11 to the lower hanging heddle hook 54.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
