Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a needle-type warp thread guiding mechanism. Background Technology

[0002] In a biaxially oriented knitted structure with warp and weft yarns, the warp yarns need to be vertically positioned in the center of the fabric and then interweave with the weft and knitting yarns on both sides. This knitting process results in the warp exit area becoming a densely populated area where various machine parts and yarns converge, specifically located between the teeth of the front and rear needle beds. This area needs to accommodate the laterally arranged warp yarn guides, the knitting needles that undulate and hook the yarn within the front and rear needle beds, and the weft and knitting yarn guides running before and after the warp yarns, respectively. Therefore, the structural dimensions of the warp yarn guides are particularly critical, directly affecting the smoothness of yarn guidance.

[0003] In the prior art, for example, Chinese Patent Application Publication No. CN 115305629 A discloses a yarn feeding device and knitting method for a flat knitting machine with a warp and weft biaxial knitting structure, which uses a traditional yarn guide to feed the warp yarn. However, such yarn guides are large in size, occupy too much space, and are difficult to insert deeply into the middle area of ​​the front and rear needle bed teeth. This causes spatial interference between them and the weft yarn guide, the knitting yarn guide, and the undulating knitting needles in the front and rear needle beds, squeezing out the key shared cooperation space, making it difficult to achieve stable and efficient mass production knitting in actual production.

[0004] Another existing technology, such as the biaxial warp and weft yarn guiding system disclosed in Chinese Patent Publication No. CN 221235718 U, attempts to solve the problem of large space occupation of traditional yarn guides by feeding warp yarns through a group of yarn guide tubes installed on the flat knitting machine slide rail. However, the wall thickness of the yarn guide tube itself still occupies a considerable amount of space, and it is also unable to effectively insert into the middle area between the front and rear needle bed teeth. This space limitation problem has not been fundamentally solved. If the warp yarn guide does not reach the predetermined depth, the warp yarns guided by the yarn guide will twist under the attraction of the fabric below the outlet of the warp yarn guide. This will cause the undulating knitting needles to mishook onto the warp yarns, which also restricts the mass production of knitted fabrics. Utility Model Content

[0005] The purpose of this invention is to provide a needle-type warp thread guiding mechanism that is simple in structure, convenient for threading warp threads, compact in size and occupies little space, and can ensure that the warp threads are properly guided.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] The guide needle type warp yarn guiding mechanism includes several yarn inlet holes, and several guide needles (in the shape of fine needles) are arranged below the several yarn inlet holes. The lower end of the guide needle has a yarn outlet hole, which is located between the front needle bed and the rear needle bed teeth. The warp yarn is distributed vertically through the yarn inlet holes and the yarn outlet holes.

[0008] To facilitate yarn feeding and output and reduce friction, the yarn outlet hole has a shuttle-shaped structure.

[0009] The yarn inlet hole and the yarn guide needle are disposed on the yarn guide component, which has a horizontal plate and a vertical plate. The yarn inlet hole is disposed on the horizontal plate, and the head end of the yarn guide needle is mounted on the vertical plate.

[0010] The yarn guide is mounted on the slide rail via a slider base, which facilitates adjustment of the slider base's position on the slide rail. The yarn guide needle is inserted into the middle of the teeth of the front and rear needle beds, located in the gap between the knitting needles of the front needle bed and the knitting needles of the adjacent rear needle bed.

[0011] To save space and reduce the resistance of the yarn entering the yarn outlet, the surface of the yarn guide needle has a yarn travel groove along the length of the guide needle.

[0012] To prevent the undulating knitting needles (the needles used during knitting) from snagging the warp threads, the yarn guide needle's exit hole extends into the gap between the front needle bed knitting needle and its adjacent back needle bed knitting needle, located below the point where the front and back needles meet during knitting, and on the back side of the front and back needles. This ensures that even if the warp threads twist under the fabric's gravity, the knitting needles will not snag on them.

[0013] The warp yarn guiding mechanism provided by this utility model includes vertically distributed yarn inlet and yarn outlet holes. The warp yarn enters through the yarn inlet hole and exits through the yarn outlet hole, which not only facilitates yarn passage and ensures the vertical positioning accuracy of the warp yarn in the knitted fabric, but also reduces the resistance to warp yarn guidance. The guiding needle can penetrate deep into the middle area of ​​the front and rear needle bed teeth and extend into the gap between the front needle bed knitting needle and its adjacent rear needle bed knitting needle, located below the intersection point of the front and rear needle bed knitting needles during knitting, and on the back side of the front and rear needle bed knitting needles. The guiding needle is connected to the slide rail via a slider base, located at the teeth of the front and rear needle beds, and can be adjusted left and right, and up and down.

[0014] The needle-type warp thread guiding mechanism provided in this utility model has a simple structure and facilitates the insertion of warp threads. It not only significantly reduces space occupation but also ensures that the warp threads are properly guided. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Figure 3 This is a schematic diagram of the yarn guide and the yarn guide needle. Detailed Implementation

[0019] like Figure 1 , 2 As shown in Figure 3, the needle-type warp thread guiding mechanism includes a yarn guide 8 located above the teeth of the front needle bed 5 and the rear needle bed 5' of the computer flat knitting machine. The yarn guide 8 has a horizontal plate 81 and a vertical plate 82. The horizontal plate 81 and the vertical plate 82 are connected to form a right angle or near right angle. Several yarn inlet holes 7 are arranged at equal intervals (unequal intervals are also possible) on the horizontal plate 81. Several yarn guide needles 2 are arranged below the several yarn inlet holes 7. One yarn guide needle 2 can be arranged below one yarn inlet hole 7. Of course, one yarn inlet hole 7 can correspond to multiple adjacent yarn guide needles 2. Of course, one yarn inlet hole 7 can also correspond to multiple non-adjacent yarn guide needles 2 (this situation will cause the yarn inlet path to bend and form resistance). There is no strict limitation here. 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 outlet hole 9, which is located between the teeth of the front needle bed 5 and the rear needle bed 5'. The warp yarn 1 is distributed vertically through the yarn inlet hole 7 and the yarn outlet hole 9 and is guided into the teeth of the front needle bed 5 and the rear needle bed 5'. In use, multiple warp yarns are inserted into different yarn inlet holes 7, and then exit through the corresponding yarn outlet holes 9 below the yarn inlet holes, and are guided into the teeth of the front needle bed 5 and the rear needle bed 5'. The multiple warp yarns are distributed vertically above the teeth; that is, after a warp yarn 1 is inserted through a yarn inlet hole 7, it exits through the yarn outlet hole 9 below the yarn inlet hole 7 and is guided into the teeth of the front needle bed 5 and the rear needle bed 5'.

[0020] To save space and reduce the resistance of the yarn entering the yarn outlet, the surface of the yarn guide needle 2 has a yarn travel groove along the length of the yarn guide needle 2.

[0021] The yarn guide 8 is connected to the slider base 4 via a connecting rod 6, so that the yarn guide 8 can be mounted on the slide rail 3 via the slider base 4. Of course, multiple sets of connecting rods 6 and slider bases 4 are provided between the yarn guide 8 and the slide rail 3 so that the yarn guide 8 can be mounted on the slide rail 3.

[0022] To facilitate lateral adjustment of the horizontal position of the guide needle 2, the slider base 4 can slide along the slide rail 3 to insert the guide needle 2 into the middle of the teeth of the front and rear needle beds, extending into the gap between the knitting needles of the front needle bed 5 and the adjacent knitting needles of the rear needle bed 5', located below the intersection point of the knitting needles of the front and rear needle beds 5', and on the back side of the knitting needles of the front and rear needle beds 5'. For example, the slider base 4 is provided with a slider, and the slide rail 3 is provided with a groove, with the slider connected in the groove, allowing the slider base 4 to slide laterally along the slide rail 3. To lock the position of the slider base 4 on the slide rail 3, a locking mechanism is also provided between the slider base 4 and the slide rail 3. The locking mechanism can adopt a mechanism commonly used in the prior art, for example, the slider base 4 is locked to the slide rail 3 by bolts.

[0023] To facilitate adjustment of the height of the yarn hole 9, the connecting rod 6 can move up and down on the slider base 4. For example, the connecting rod 6 has a waist-shaped hole, and a bolt is installed in the waist-shaped hole. The bolt secures the connecting rod 6 to the slider base 4. When the connecting rod 6 moves up and down on the slider base 4, the bolt moves in the waist-shaped hole.

[0024] The guide needle type warp yarn guiding mechanism provided in this embodiment includes a yarn inlet hole 7 and a yarn outlet hole 9 arranged vertically. The warp yarn enters through the yarn inlet hole 7 and exits through the yarn outlet hole 9, which not only facilitates the passing of the yarn and ensures the central vertical positioning accuracy of the warp yarn in the knitted fabric, but also reduces the resistance of the warp yarn guiding. The guide needle 2 can penetrate deep into the middle area of ​​the front and rear needle beds 5 and 5', and extend into the gap between the knitting needle of the front needle bed 5 and the knitting needle of the adjacent rear needle bed 5'. It is located below the intersection point of the knitting needles of the front and rear needle beds 5' during knitting, and is located on the back side of the knitting needles of the front and rear needle beds 5'. The guide needle 2 is connected to the slide rail 3 through the connecting rod 6 and the slider base 4, located at the tooth opening of the front and rear needle beds 5', and can be adjusted left and right and up and down.

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

[0026] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
