Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machinery, in particular to a needle type warp thread guide mechanism. BACKGROUND

[0002] In the double-axial warp-knitting structure, the warp yarn needs to be positioned vertically in the center of the fabric and double-face composite interlaced with the weft yarn and the knitting yarn in front and back of the warp yarn. This knitting process causes the warp yarn outlet area to become a dense area where various machine parts and yarns intersect, specifically in the middle of the tooth gap of the front and back needle beds. This area needs to accommodate the horizontally arranged warp yarn guide, the knitting needle that hooks the yarn in the front and back needle beds, and the weft yarn guide and knitting yarn guide that run in front and back of the warp yarn, respectively. Therefore, the structure size of the warp thread guide is particularly critical, directly affecting the smoothness of the guide.

[0003] In the prior art, for example, a yarn feeding device and a knitting method for a double-axial warp-knitting structure of a flat knitting machine are disclosed in Chinese Patent Application Publication No. CN 115305629 A, which uses a traditional guide to feed the warp yarn. However, such a guide is relatively large in size and occupies too much space, making it difficult to be deeply inserted into the middle area of the tooth gap of the front and back needle beds. This causes space interference between the guide and the weft yarn guide, the knitting yarn guide, and the knitting needle that moves up and down in the front and back needle beds, and occupies the key shared space, making it difficult to achieve stable and efficient mass production in actual production.

[0004] Another prior art, such as a double-axial warp-weft insertion knitting guide system disclosed in Chinese Patent No. CN 221235718 U, attempts to feed the warp yarn through a guide tube group installed on the slide rail of the flat knitting machine to solve the problem of large space occupation of the traditional guide. However, the thickness of the guide tube wall itself still occupies a considerable space, and it is also difficult to effectively insert into the middle area of the tooth gap of the front and back needle beds. This space limitation problem has not been fundamentally solved, and if the warp thread guide does not reach the predetermined depth position, the warp thread guided by the warp thread guide will be twisted under the outlet of the warp thread guide due to the gravity of the fabric, which will cause the knitting needle to hook to the warp thread, also restricting the mass production of the knitted fabric. SUMMARY

[0005] The purpose of the present application is to provide a needle type warp thread guide mechanism that is simple in structure, convenient to wear, compact in size, small in space occupation, and can ensure that the warp thread is guided in place.

[0006] In order to achieve the above technical purpose, the technical scheme of the present application is:

[0007] The needle type warp thread leading-in mechanism comprises a plurality of yarn leading holes, a plurality of yarn guiding needles (thin needle type) arranged below the yarn leading holes, the lower end of the yarn guiding needle having a yarn leading-out hole, the yarn leading-out hole being located between the front needle bed and the back needle bed, and the warp thread being distributed up and down through the yarn leading hole and the yarn leading-out hole.

[0008] In order to facilitate the leading-in and leading-out of the yarn and reduce the friction, the yarn leading-out hole is in a shuttle shape.

[0009] The yarn leading hole and the yarn guiding needle are arranged on a yarn guiding member, the yarn guiding member having a horizontal plate and a vertical plate, the yarn leading hole being arranged on the horizontal plate, and the head end of the yarn guiding needle being mounted on the vertical plate.

[0010] The yarn guiding member is mounted on the slide rail through a slide block base, the position of the slide block base on the slide rail is adjusted, the yarn guiding needle is inserted into the gap between the tooth gap of the front needle bed and the back needle bed, and is located in the gap between the knitting needle of the front needle bed and the knitting needle adjacent to the back needle bed.

[0011] In order to save space and reduce the resistance of the yarn entering the yarn leading-out hole, the yarn guiding needle has a yarn running groove on the surface along the length direction of the yarn guiding needle.

[0012] In order to prevent the knitting needle (the needle during knitting) from being hooked to the warp thread, the yarn leading-out hole of the yarn guiding needle extends into the gap between the knitting needle of the front needle bed and the knitting needle adjacent to the back needle bed, is located below the intersection point of the knitting needle of the front needle bed and the knitting needle of the back needle bed during knitting, and is located on the back surface of the knitting needle of the front needle bed and the knitting needle of the back needle bed. In this way, even if the warp thread is twisted under the attraction of the fabric, the knitting needle will not be hooked to the warp thread.

[0013] The needle type warp thread leading-in mechanism provided by the application comprises yarn leading holes and yarn leading-out holes arranged vertically, the warp thread is led in through the yarn leading hole and led out through the yarn leading-out hole, the resistance of the warp thread leading-in is reduced, the yarn guiding needle can be deeply inserted into the middle area of the tooth gap of the front needle bed and the back needle bed, and extends into the gap between the knitting needle of the front needle bed and the knitting needle adjacent to the back needle bed, is located below the intersection point of the knitting needle of the front needle bed and the knitting needle of the back needle bed during knitting, and is located on the back surface of the knitting needle of the front needle bed and the knitting needle of the back needle bed. The yarn guiding needle is connected to the slide rail through a slide block base and is located at the tooth gap of the front needle bed and the back needle bed, and can be adjusted left and right and up and down.

[0014] The needle type warp thread leading-in mechanism provided by the application is simple in structure, convenient for the warp thread to be led in, significantly reduces the space occupation, and ensures that the warp thread is led in to the right position. BRIEF DESCRIPTION OF DRAWINGS

[0019] As shown in FIGS. Figure 1 , 2 , the needle guide warp yarn introduction mechanism includes a yarn guide 8 above the tooth gap of the front needle bed 5 and the back needle bed 5` of the computerized flat knitting machine. The yarn guide 8 has a horizontal plate 81 and a vertical plate 82 connected to form a right angle or an approximate right angle. A plurality of yarn entry holes 7 are arranged at equal intervals (or unequal intervals) on the horizontal plate 81. A plurality of yarn guide needles 2 are arranged below the yarn entry holes 7. One yarn guide needle 2 can be arranged below one yarn entry hole 7. Alternatively, one yarn entry hole 7 can correspond to a plurality of adjacent yarn guide needles 2. Alternatively, one yarn entry hole 7 can correspond to a plurality of non-adjacent yarn guide needles 2 (which will cause the yarn path to bend and form resistance). The head end of the yarn guide needle 2 is connected to the vertical plate 82. The lower end of the yarn guide needle 2 has a yarn exit hole 9 located between the tooth gap of the front needle bed 5 and the back needle bed 5`. The warp yarn 1 is distributed above and below the tooth gap through the yarn entry hole 7 and the yarn exit hole 9 and introduced into the tooth gap of the front needle bed 5 and the back needle bed 5`. In use, a plurality of warp yarns are respectively inserted into different yarn entry holes 7 and then respectively inserted into the yarn exit holes 9 below the yarn entry holes 7 and introduced into the tooth gap between the front needle bed 5 and the back needle bed 5`. The plurality of warp yarns are sequentially distributed above and below the tooth gap.

[0020] In order to save space and reduce the resistance of the yarn entering the yarn exit hole, the surface of the yarn guide needle 2 has a yarn running groove along the length direction of the yarn guide needle 2.

[0021] The yarn guide 8 is connected to the slide block base 4 through the connecting rod 6, so that the yarn guide 8 can be installed on the slide rail 3 through the slide block base 4. Of course, a plurality of sets of connecting rods 6 and slide block bases 4 are arranged between the yarn guide 8 and the slide rail 3 to enable the yarn guide 8 to be mounted on the slide rail 3.

[0022] In order to facilitate the horizontal adjustment of the horizontal position of the guide needle 2, the slider base 4 can be displaced along the slide rail 3, so as to insert the guide needle 2 into the middle of the tooth gap of the front and rear needle beds, and extend into the gap between the knitting needles of the front needle bed 5 and the knitting needles adjacent thereto of the rear needle bed 5`, below the intersection point of the knitting of the knitting needles of the front needle bed 5 and the knitting needles of the rear needle bed 5`, and on the back of the knitting needles of the front needle bed 5 and the knitting needles of the rear needle bed 5`. For example, the slider base 4 is provided with a sliding block, the slide rail 3 is provided with a sliding groove, and the sliding block is connected in the sliding groove, so that the slider base 4 can slide horizontally along the slide rail 3. In order to lock the position of the slider base 4 on the slide rail 3, a locking mechanism is further arranged between the slider base 4 and the slide rail 3, which can adopt the mechanism commonly used in the prior art, for example, the slider base 4 is locked on the slide rail 3 by bolts.

[0023] In order to facilitate the adjustment of the height of the yarn outlet hole 9, the connecting rod 6 can be displaced up and down on the slider base 4. For example, the connecting rod 6 has a waist-shaped hole, a bolt is arranged in the waist-shaped hole, the bolt tightly connects the connecting rod 6 to the slider base 4, and when the connecting rod 6 is displaced up and down on the slider base 4, the bolt is displaced in the waist-shaped hole.

[0024] The guide needle type warp thread introduction mechanism provided by the embodiment includes the yarn inlet hole 7 and the yarn outlet hole 9 arranged vertically and combined, the warp thread is inserted through the yarn inlet hole 7 and is drawn out through the yarn outlet hole 9, which not only facilitates the threading and ensures the central vertical positioning accuracy of the warp thread in the knitted fabric, but also reduces the resistance of the warp thread introduction. The guide needle 2 can be deeply inserted into the middle region of the tooth gap of the front and rear needle beds 5, 5`, and extend into the gap between the knitting needles of the front needle bed 5 and the knitting needles adjacent thereto of the rear needle bed 5`, below the intersection point of the knitting of the knitting needles of the front needle bed 5 and the knitting needles of the rear needle bed 5`, and on the back of the knitting needles of the front needle bed 5 and the knitting needles of the rear needle bed 5`. The guide needle 2 is connected to the slide rail 3 through the connecting rod 6 and the slider base 4, and can be adjusted left and right and up and down.

[0025] Of course, as other embodiments, the yarn inlet hole 7 can be arranged on other components, for example, the yarn inlet hole 7 is arranged on the slide rail 3; or the yarn inlet hole 7 is arranged on the yarn guide plate above the slide rail 3.

[0026] The above embodiments do not limit the present application in any way, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present application.
