Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warp knitting machines, in particular to a warp knitting machine automatic opening gauge adjusting device. BACKGROUND

[0002] A warp knitting machine is a machine used to produce knitted fabrics, which produces fabrics with specific structures and textures through a specific knitting process. The knock-over plate is an important component of the warp knitting machine, which can help control the tension and position of the yarn during the knitting process, ensuring the quality and structure of the fabric. When the warp knitting machine is knitting fabric, in order to adapt to the needs of fabrics of different thicknesses, the opening gauge is adjusted by finely adjusting the distance between the two knock-over plates within a certain adjustable range to ensure that the woven fabric meets the expected density and structure standards. For example, the utility model patent with the authorization announcement number CN210002034U provides a warp knitting machine knock-over opening gauge adjusting mechanism, which uses two pairs of symmetrically placed bevel gears for transmission, converts rotation in one direction to rotation in another direction, and is flexible and has small load. By controlling the rotation of the swing shaft one and the swing shaft two in opposite directions, and through the first drive assembly and the second drive assembly to drive the first knock-over support and the second knock-over support to move up and down respectively, the first knock-over plate and the second knock-over plate are controlled to move in opposite directions respectively, realizing the adjustment of the knock-over plate. When only one side of the knock-over plate needs to be adjusted, the third coupling can be loosened to adjust one side separately. However, the warp knitting machine knock-over opening gauge adjusting mechanism still has the following deficiencies: 1. It uses a manual adjustment method, the adjustment process is relatively complicated and inefficient, and it cannot realize automatic dynamic opening gauge adjustment when the warp knitting machine is working, which is not conducive to dynamic adjustment of fabric thickness and three-dimensional texture effect of the knitted fabric; 2. When only one side of the knock-over plate needs to be adjusted, manual operation is required to loosen the third coupling, which is relatively troublesome and time-consuming; 3. With the extension of the use time and the accumulation of transmission errors, the two knock-over plates may not adjust the distance consistently and synchronously, which may affect the overall quality of the knitted fabric, and regular inspection and maintenance of the equipment are required, which increases the maintenance cost and failure rate. In view of this, the problem has been studied in depth, and thus the present application is produced. SUMMARY

[0014] From the above description, the warp knitting machine automatic opening gauge adjusting device provided by the application has the following beneficial effects:

[0015] I. By setting two motion output self-locking mechanisms, when the common driving mechanism is started to make corresponding motion and the two independent driving mechanisms are not started, the motion output by the common driving mechanism can be simultaneously input from the common motion input end of the two motion output self-locking mechanisms, and then the single output of motion is realized through the self-locking motion output end of the two motion output self-locking mechanisms to drive the two lower shafts to rotate simultaneously, so as to realize the simultaneous adjustment of the rotation of the two lower shafts, and since the two motion output self-locking mechanisms are symmetrically arranged, the motion output by the two motion output self-locking mechanisms is opposite, thereby realizing the reverse rotation of the two lower shafts; when the independent driving mechanism is started to make corresponding motion and the common driving mechanism is not started, the motion output by the independent driving mechanism can be independently input from the independent motion input end of the motion output self-locking mechanism on the corresponding side, and then the single output of motion is realized through the self-locking motion output end of the motion output self-locking mechanism on the corresponding side to drive the lower shaft on the corresponding side to rotate independently, so as to realize the independent adjustment of the rotation of the lower shaft on the corresponding side; when the common driving mechanism and the independent driving mechanism work simultaneously, the motions of the common driving mechanism and the independent driving mechanism are simultaneously input into the corresponding motion output self-locking mechanisms, and the combined output of motion is realized through the self-locking motion output end of the motion output self-locking mechanism; when the common driving mechanism and the independent driving mechanism are both stopped, the motion output self-locking mechanism can also self-lock the lower shaft to effectively prevent the automatic rotation of the knock-over plate and effectively ensure the stability of the distance between the two knock-over plates after adjustment; at the same time, the setting of the two real-time rotation position recording mechanisms can record the real-time rotation positions of the two lower shafts, i.e. the adjustment distances of the two knock-over plates and the distance between the two knock-over plates after adjustment, so as to feedback and control the motion output of the common driving mechanism and / or the independent driving mechanism in real time and form a closed loop control to achieve accurate adjustment;

[0016] II. By setting the common driving mechanism, the independent driving mechanism, the motion output self-locking mechanism and the real-time rotation position recording mechanism, active adjustment can be realized, the adjustment process is simpler and more efficient, and when the warp knitting machine is working, automatic dynamic adjustment of the gauge can be realized according to the set requirements, which is beneficial to the dynamic adjustment of the thickness of the fabric and the three-dimensional texture effect of the knitted fabric;

[0017] III. When only one side of the knock-over plate needs to be adjusted, the independent driving mechanism on the corresponding side only needs to be started to drive the lower shaft on the corresponding side to rotate, so as to realize the adjustment of the knock-over plate on the corresponding side, without causing the adjustment of the knock-over plate on the other side, which facilitates the separate adjustment of the two knock-over plates, the operation is simpler and time-saving, and no shutdown operation is needed;

[0018] Four, when adjusting the distance between the two knock-over plates, the movement output by the common driving mechanism can be simultaneously input from the common movement input end of the two movement output self-locking mechanisms, and through the transmission of the movement output self-locking mechanism, the two lower rotating shafts can be driven to rotate reversely at the same time, thereby driving the two knock-over plates to move towards each other or away from each other, so as to adjust the distance between the two knock-over plates. At the same time, if necessary, the two independent driving mechanisms can be adaptively started, and the corresponding independent driving mechanism on the side in need can drive the lower rotating shaft on the corresponding side to rotate independently through the transmission of the movement output self-locking mechanism, so as to independently adjust the rotation of the lower rotating shaft on the corresponding side, thereby independently assisting the fine adjustment of the movement of the knock-over plate on the corresponding side. Thus, the movement output by the corresponding movement output self-locking mechanism is synthesized with the movement input by the common driving mechanism and the independent driving mechanism on the corresponding side, so as to eliminate the influence of transmission error accumulation, effectively avoid the problem that the distances adjusted by the two knock-over plates are inconsistent and out of sync, and effectively ensure that the distance between the two knock-over plates after adjustment meets the set requirements, thereby ensuring the overall quality of the knitted fabric, which is conducive to greatly reducing the frequency of periodic inspection and maintenance, thereby reducing maintenance costs and failure rate.

Detailed Implementation

[0026] The present invention will be further described below through specific embodiments.

[0027] like Figures 1 to 6 As shown, the automatic opening device for a warp knitting machine according to the present invention includes an adjustment component 1 and two symmetrically arranged opening components 2. The adjustment component 1 is used to drive the lower rotating shafts 21 of the two opening components 2 to rotate, thereby causing the release plates 22 of the two opening components 2 to move closer to or further away from each other. The adjustment component 1 includes a common drive mechanism 3, two independent drive mechanisms 4, two symmetrically arranged motion output self-locking mechanisms 5, and two real-time rotation position recording mechanisms 6. The motion output self-locking mechanism 5 is provided with a common motion input end, an independent motion input end, and a self-locking motion output end. The common drive mechanism 3... The common motion input end of each of the two motion output self-locking mechanisms 5 is driven by the two independent drive mechanisms 4, which are respectively driven by the two independent motion input ends of the two motion output self-locking mechanisms 5. The self-locking motion output ends of the two motion output self-locking mechanisms 5 are respectively driven by the two lower rotating shafts 21. The motion output self-locking mechanism 5 is used to output the motion input by the common drive mechanism 3 and the independent drive mechanism 4 individually or in combination, and has a self-locking function. The two real-time rotation position recording mechanisms 6 are respectively used to record the real-time rotation position of the two lower rotating shafts 21.

[0028] By the arrangement of the two motion output self-locking mechanisms 5, when the common driving mechanism 3 is activated to make corresponding motion while the independent driving mechanisms 4 are not activated, the motion output by the common driving mechanism 3 can be simultaneously input from the common motion input ends of the two motion output self-locking mechanisms 5, and then the single output of motion is realized through the self-locking motion output ends of the two motion output self-locking mechanisms 5 to drive the two lower rotating shafts 21 to rotate simultaneously, so as to realize the simultaneous adjustment of the rotation of the two lower rotating shafts 21, and since the two motion output self-locking mechanisms 5 are symmetrically arranged, the motions output by the two motion output self-locking mechanisms 5 are opposite, so as to realize the reverse rotation of the two lower rotating shafts 21; when the independent driving mechanisms 4 are activated to make corresponding motion while the common driving mechanism 3 is not activated, the motion output by the independent driving mechanisms 4 can be independently input from the independent motion input ends of the motion output self-locking mechanisms 5 on the corresponding side, and then the single output of motion is realized through the self-locking motion output ends of the motion output self-locking mechanisms 5 on the corresponding side to drive the lower rotating shafts 21 on the corresponding side to rotate independently, so as to realize the independent adjustment of the rotation of the lower rotating shafts 21 on the corresponding side; when the common driving mechanism 3 and the independent driving mechanisms 4 work simultaneously, the motions of the common driving mechanism 3 and the independent driving mechanisms 4 are simultaneously input into the corresponding motion output self-locking mechanisms 5, and the combined output of motion is realized through the self-locking motion output ends of the motion output self-locking mechanisms 5; when the common driving mechanism 3 and the independent driving mechanisms 4 are both stopped, the motion output self-locking mechanisms 5 can also play a self-locking role on the lower rotating shafts 21, so as to effectively prevent the automatic rotation of the release plates 22 and effectively ensure the stability of the distance between the two release plates 22 after adjustment; meanwhile, in cooperation with the arrangement of the two real-time rotating position recording mechanisms 6, the real-time rotating positions of the two lower rotating shafts 21 can be recorded, i.e. the adjustment distances of the two release plates 22 and the distance between the two release plates 22 after adjustment are recorded in real time, so as to feedback and control the motion output of the common driving mechanism 3 and / or the independent driving mechanisms 4 in real time, and form a closed loop control to achieve the purpose of accurate adjustment.

[0029] Therefore, through the arrangement of the common driving mechanism 3, the independent driving mechanism 4, the motion output self-locking mechanism 5 and the real-time rotation position recording mechanism 6, active adjustment can be realized, and the adjustment process is simpler and more efficient. During the operation of the warp knitting machine, automatic dynamic opening of the gauge can be realized according to the set requirements, which is beneficial to realize dynamic adjustment of the fabric thickness and the three-dimensional texture effect of the knitted fabric. When only one side of the knock-over plate 22 needs to be adjusted, the corresponding independent driving mechanism 4 is only needed to be started to drive the corresponding lower rotating shaft 21 to rotate, so that the purpose of adjusting the corresponding knock-over plate 22 is achieved, and the other knock-over plate 22 will not be adjusted. The two knock-over plates 22 can be independently adjusted separately, which is more simple and time-saving in operation, and does not need to stop the machine. When adjusting the distance between the two knock-over plates 22, the motion output by the common driving mechanism 3 can be simultaneously input from the common motion input end of the two motion output self-locking mechanisms 5, and the two lower rotating shafts 21 can be driven to rotate in opposite directions at the same time through the transmission of the motion output self-locking mechanism 5, so that the two knock-over plates 22 are moved closer to each other or farther away from each other, to adjust the distance between the two knock-over plates 22. At the same time, if necessary, the two independent driving mechanisms 4 can be adaptively started, and the independent driving mechanism 4 on the side that needs adjustment drives the lower rotating shaft 21 on the corresponding side to rotate independently through the transmission of the motion output self-locking mechanism 5, to realize independent adjustment of the rotation of the lower rotating shaft 21 on the corresponding side, thereby realizing independent auxiliary fine adjustment of the motion of the knock-over plate 22 on the corresponding side. Therefore, the motion output self-locking mechanism 5 on the corresponding side combines the motion input by the common driving mechanism 3 and the independent driving mechanism 4 on the corresponding side, to eliminate the influence of transmission error accumulation, effectively avoid the problem that the two knock-over plates 22 are adjusted at different distances and out of sync, and effectively ensure that the distance between the two knock-over plates 22 after adjustment meets the set requirements, to ensure the overall quality of the knitted fabric, which is beneficial to greatly reduce the frequency of regular inspection and maintenance, to reduce maintenance costs and failure rate.
