Description

Technical Field

[0001] The invention relates to the technical field of automatic warp drawing-in, and in particular to a heald stabilizing mechanism and automatic warp drawing-in equipment. Background Art

[0002] During the weaving process, it is necessary to accurately separate the single heald from the stacking queue and feed it into the lead-in system at high speed. When the textile equipment is working, it is necessary to first stack the healds in large quantities at one time in the heald storage area, and then transport them to the corresponding process position on the automatic warp drawing machine for high-speed separation of the single heald. Due to the slender shape of the heald, the heald will swing and deform greatly during the high-speed separation process, and the heald oscillation is in an unstable state. In order to ensure that the single heald enters the transfer mechanism smoothly, the warp drawing machine must wait for a period of time to allow the heald to stop oscillating and be in a stable state. This process takes a lot of time and reduces production efficiency. Therefore, there is an urgent need for an automatic warp drawing device to increase the warp drawing speed and thus improve production efficiency. Summary of the invention

[0003] Based on this, the present application provides a heald stabilizing mechanism, which can effectively reduce the vibration of the healds during high-speed separation, so as to increase the threading speed and improve production efficiency.

[0006] The above heald stabilization mechanism can adjust the blocking force of the damping plate to adapt to different types of healds. When the automatic threading equipment is working, the heald separation mechanism can separate a single heald from the stacked state. Under the action of the heald moving mechanism, the lower part of the single heald moves at high speed along the lower string rod to the lower heald. During the movement, the single heald contacts the damping plate and squeezes the damping plate into the guide plate. This process will greatly consume the oscillation energy of the single heald and reduce the swing amplitude of the single heald. After the single heald is out of contact with the damping plate, the damping plate resets to further prevent the single heald from swinging back, which can effectively reduce the oscillation of the heald during high-speed separation, so as to increase the threading speed and improve production efficiency.

[0029] The warp drawing machine is a kind of textile equipment, which is mainly used to insert the warp yarn into the heald eye and the reed tooth to ensure that the warp yarn is temporarily and partially fixed in terms of arrangement order, arrangement width and density. Its function is to insert the warp yarn into the heald eye and the reed tooth in a specific arrangement through mechanical operation to ensure the stability and accuracy of the warp yarn during the weaving process. The warp drawing machine reduces the labor intensity, improves production efficiency and ensures the quality of the warp drawing through automation or semi-automation. In the weaving process, it is necessary to accurately separate the single heald from the stacking queue and feed it into the lead-in system at high speed. When the textile equipment is working, it is necessary to first stack the healds in large quantities at the heald storage place at one time, and then transport them to the corresponding process position on the automatic warp drawing machine for high-speed separation of the single heald. Due to the slender shape of the heald, the heald will swing and deform greatly during the high-speed separation process, and the heald oscillation is in an unstable state. In order to ensure that the single heald enters the transfer mechanism smoothly, the warp drawing machine must wait for a period of time to let the heald stop oscillating and be in a stable state. This process takes a lot of time and reduces production efficiency. Therefore, there is an urgent need for an automatic warp drawing device to increase the warp drawing speed and thus improve production efficiency.

[0030] See also Figure 1 to Figure 7 In order to solve the above problems, the embodiment of the present application provides a heald stabilizing mechanism 60, which is applied to the automatic warp drawing device 10. The automatic warp drawing device 10 includes a base 20, a heald storage mechanism 30, a heald separation mechanism 40, a heald moving mechanism 50 and a heald stabilizing mechanism 60; the heald storage mechanism 30 includes an upper string rod 31 and a lower string rod 32 arranged on the base 20 and spaced apart in the height direction, and the upper string rod 31 and the lower string rod 32 are respectively used to insert the two ends of the heald 11; the heald separation mechanism 40 is arranged on the base 20 and located between the upper string rod 31 and the lower string rod 32, and the heald separation mechanism 40 is used to separate the multiple healds 11 stacked between the upper string rod 31 and the lower string rod 32 into separate healds 11 along the first direction P1; the heald moving mechanism 50 includes an upper heald piece 51, a lower heald piece 52, an upper heald hook 53 and a lower heald hook 54 arranged on the base 20 The upper heald piece 51 is located between the upper heald hook 53 and the string rod, and the lower heald piece 52 is located between the lower heald hook 54 and the lower string rod 32. The upper heald piece 51 is used to buckle one end of the heald 11 located on the upper string rod 31 into the upper heald hook 53, and the lower heald piece 52 is used to buckle one end of the heald 11 located on the lower string rod 32 into the lower heald hook 54; the heald stabilizing mechanism 60 includes a bottom plate 6 located between the upper heald piece 51 and the lower heald piece 52 1. Guide plate 62 and damping plate 63. The bottom plate 61 is arranged on the base 20. The guide plate 62 is arranged on the bottom plate 61. The damping plate 63 is elastically connected to the guide plate 62 so as to relatively extend and retract into the edge of the guide plate 62 along the second direction P2. The heald 11 presses the damping plate 63 during the process of moving from the upper string rod 31 and the lower string rod 32 to the upper hanging heald hook 53 and the lower hanging heald hook 54. The second direction P2 is perpendicular to the height direction and the first direction P1.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the automatic threading device 10 includes a base 20, a heald storage mechanism 30, a heald separation mechanism 40 and a heald moving mechanism 50. The heald storage mechanism 30 is arranged on the base 20. There are many healds 11 to be loaded on the heald 11 storage mechanism. Specifically, the heald 11 storage mechanism includes an upper string rod 31 and a lower string rod 32. The upper string rod 31 and the lower string rod 32 are arranged at intervals in the height direction. In some embodiments, the upper string rod 31 and the lower string rod 32 are arranged in parallel. Through holes are respectively provided at the two ends of the heald 11, and the upper string rod 31 and the lower string rod 32 are respectively inserted into the through holes at the two ends of the heald 11. For example, the upper string rod 31 is inserted into the first through hole of the plurality of healds 11, and the lower string rod 32 is inserted into the second through hole of the plurality of healds 11, so that the plurality of healds 11 are placed in parallel on the heald 11 storage mechanism, and are stored in a stacked state on the upper string rod 31 and the lower string rod 32, so that the heald separation mechanism 40 can separate the plurality of healds 11 in the next process. In some embodiments, the first through hole and the second through hole are U-slot holes. The heald separation mechanism 40 is provided on the base 20. The heald separation mechanism 40 can separate a single heald 11 from the heald 11 queue in the heald storage mechanism 30. Specifically, the heald separation mechanism 40 is located between the upper string rod 31 and the lower string rod 32. The heald separation mechanism 40 is used to separate the multiple healds 11 stacked between the upper string rod 31 and the lower string rod 32 into individual healds 11 along the first direction P1. The heald moving mechanism 50 is provided on the base 20. The heald moving mechanism 50 can transfer the heald 11 to the warp drawing station. Specifically, the heald moving mechanism 50 includes an upper heald piece 51, a lower heald piece 52, an upper heald hook 53 and a lower heald hook 54. The upper heald hook 53 and the lower heald hook 54 can play the role of fixing and adjusting the heald 11, ensuring the production efficiency of the automatic warp drawing device 10. The upper heald piece 51 is located between the upper heald hook 53 and the upper string rod 31, and the lower heald piece 52 is located between the lower heald hook 54 and the lower string rod 32. The upper heald piece 51 is used to buckle one end of the heald 11 located on the upper string rod 31 into the upper heald hook 53, and the lower heald piece 52 is used to buckle one end of the heald 11 located on the lower string rod 32 into the lower heald hook 54. The upper heald piece 51 and the lower heald piece 52 can buckle the two ends of the same heald 11 into the upper heald hook 53 and the lower heald hook 54, respectively. In some embodiments, the rotation axis of the upper heald piece 51 is parallel to the first direction P1, and the rotation axis of the lower heald piece 52 is parallel to the second direction P2, so that the separated heald 11 can be buckled smoothly into the upper heald hook 53 and the lower heald hook 54. In some embodiments, the base 20 is provided with two heald wire 11 storage mechanisms and a heald wire moving mechanism 50 at intervals in the second direction P2, and the guide plate 62 is provided with a damping plate 63 on the opposite sides of the second direction P2 respectively. The two sets of heald wire 11 storage mechanisms and the heald wire moving mechanism 50 can separate and move the heald wire 11 on both sides at the same time, thereby improving the working efficiency of the automatic threading device 10.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the heald stabilizing mechanism 60 includes a bottom plate 61, a guide plate 62, and a damping plate 63 located between the upper heald piece 51 and the lower heald piece 52. The heald stabilizing mechanism 60 can adjust the blocking force of the damping plate 63 to adapt to different types of healds 11. When the automatic threading device 10 is working, the heald separation mechanism 40 can separate the single heald 11 from the stacked state. Under the action of the heald moving mechanism 50, the lower part of the single heald 11 moves at high speed along the lower string rod 32 to the lower heald piece 52. During the movement, the single heald 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 heald 11, reducing the swing amplitude of the single heald 11. After the single heald 11 is out of contact with the damping plate 63, the damping plate 63 is reset to further prevent the single heald 11 from swinging back. Without the heald stabilizing mechanism 60, the single heald 11 will have a large oscillation amplitude back and forth, and may swing outside the upper heald 51. It is necessary to wait for the lower moving member to move, push the lower part of the single heald 11 into the lower hanging heald hook 54, and then wait for the lower hanging heald hook 54 to tighten the heald 11 before executing the upper heald mechanism. This set of actions will take more time in terms of timing, reducing production efficiency. Therefore, the setting of the heald stabilizing mechanism 60 avoids the situation in the prior art that it is necessary to wait for a period of time for the heald 11 to stop oscillating and be in a stable state, and can effectively reduce the oscillation of the heald 11 during high-speed separation, so as to increase the threading speed and improve production efficiency. Specifically, the bottom plate 61 of the heald stabilizing mechanism 60 is arranged on the base 20, and the guide plate 62 is arranged on the bottom plate 61. The guide plate 62 can guide the movement of the heald 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 extends out and retracts into the edge of the guide plate 62 relatively along the second direction P2. The heald 11 presses against the damping plate 63 during the process of moving from the upper string rod 31 and the lower string rod 32 to the upper hanging heald hook 53 and the lower hanging heald hook 54. The second direction P2 is perpendicular to the height direction and the first direction P1.

[0033] See also 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, so that the heald 11 can be pressed against and slide over the damping plate 63 more smoothly. The damping plate 63 protrudes from the guide plate 62 along the first direction P1, and the protruding structure is conducive to limiting the rebound of the heald 11 to the side of the damping plate 63, and more effectively limiting the position of the heald 11 after passing through the damping plate 63. The width of the guide plate 62 at the two opposite edges where the damping plate 63 is provided gradually increases along the first direction P1, and the middle part of the heald 11 moves along the guide plate 62 and squeezes the damping plate 63 into the guide plate 62. After the heald 11 is in place, the damping plate 63 rebounds.

[0034] See also 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 member 64 is provided between the guide plate 62 and the damping plate 63, so that the damping plate 63 is relatively flexible when extending and retracting relative to the guide plate 62. In the initial position, the damping plate 63 is in an extended state. When the vibrating heald 11 is separated from the heald separation mechanism 40 and passes through the heald stabilization mechanism 60, the damping plate 63 will be in a retracted state. The guide plate 62 is provided with a plurality of gear holes 621, which can be used to adjust the blocking force of the damping plate 63 to adapt to different types of healds 11. Specifically, one end of the elastic member 64 is fixed to one of the gear holes 621, and the other end is fixed to the damping plate 63. The gear holes 621 are fixed to different gear holes 621, and the elastic force of the elastic member 64 on the damping plate 63 is different, so that the heald stabilizing mechanism 60 has an adjustable function, and the blocking force of the heald stabilizing mechanism 60 can be adjusted according to the type of heald 11, thereby improving the practicality and convenience of the heald stabilizing mechanism 60. For example, three types of gear holes 621 adapted to the type of heald 11 commonly used in daily life can be set, and different gear holes 621 are arranged at intervals. In some embodiments, the elastic member 64 can be a damping spring, which is an elastic element between the device and the supporting structure, and is composed of a spiral steel spring after damping treatment. The damping spring can reduce the vibration or impact force transmitted from the heald 11 to the damping plate 63 or from the damping plate 63 to the heald 11. The working principle of the damping spring is to dissipate the motion energy by providing resistance to movement. It has the dual advantages of low frequency and large damping of the steel spring shock absorber, and can eliminate the resonance amplitude phenomenon inherent in the steel spring. In some embodiments, the bottom plate 61 is provided with a strip groove 611 extending along the second direction P2, and the guide plate 62 is movably fixed to the strip groove 611 by a fastener 612. The strip groove 611 and the fastener 612 cooperate to enable the bottom plate 61 to adapt to healds 11 of different lengths, sizes and models, so that the heald 11 can always contact the heald stabilizing mechanism 60 when passing through the heald stabilizing mechanism 60. By installing the heald stabilizing mechanism 60 on the automatic threading device 10, the timing of the action can be optimized as a whole by adjusting the action of the automatic threading device 10, which greatly improves the threading speed of the automatic threading machine and improves production efficiency.

[0035] See also Figure 3 , Figure 5 , Figure 6 and Figure 7In some embodiments, a heald guide channel 70 is provided between the lower string rod 32 and the lower heald piece 52 , and the damping plate 63 is located directly above the heald guide channel 70 , and the heald guide channel 70 can provide guidance for the movement of the separated healds 11 . In some embodiments, the heald wire moving mechanism 50 includes an upper moving member 55 and a lower moving member, the upper moving member 55 is arranged between the upper hanging heald hook 53 and the upper pulling heald piece 51, the upper moving member 55 is used to push the heald wire 11 from the upper pulling heald piece 51 to the upper hanging heald hook 53, the upper moving member 55 can adopt a rotating shaft structure, and the heald wire 11 is driven to move in a specified direction through the rotation of the rotating shaft, and then the heald wire 11 is pushed to the upper hanging heald hook 53; the lower moving member is arranged between the lower hanging heald hook 54 and the lower pulling heald piece 52, the lower moving member is used to push the heald wire 11 from the lower pulling heald piece 52 to the lower hanging heald hook 54, and the heald wire 11 is driven to move in a specified direction through the rotation of the rotating shaft, and then the heald wire 11 is pushed to the lower hanging heald hook 54.
