Technical Field

[0001] The present invention relates to the field of computer flat knitting machines, and specifically to an alternating layout structure of a toothed mouthpiece and a sinker of a computer flat knitting machine. Background Art

[0002] A computer flat knitting machine is a double needle bed latch needle weft knitting machine. In the current prior art.

[0003] The cam device of a computer flat knitting machine is like a group of planar cams, and the needle feet of the knitting needles can enter the grooves of the cams. By moving the cams, the knitting needles are forced to make regular lifting and lowering movements in the needle grooves of the needle bed, and through the actions of the needle hooks and needle tongues, the yarn is woven into a knitted fabric. During the upward movement of the knitting needles, the coils gradually exit the needle hooks, the needle tongues are opened, and the needle tongues are disengaged and hung on the needle bars; during the downward movement of the knitting needles, the needle hooks hook the newly laid yarn and pull it into a coil, while the original coil is disengaged from the needle hook, and the new coil passes through the old coil and is connected in series with the old coil to form a knitted fabric.

[0004] However, in the prior art, when the head of the knitting needle is performing knitting and needle turning operations, it is very easy to swing left and right and deflect elastically under the lateral pulling force of the yarn, resulting in missed stitches and unstable knitting patterns; therefore, an alternating layout structure of a toothed mouthpiece and a sinker of a computer flat knitting machine is proposed for the above problems. Summary of the Invention

At the same time, relying on the blowing assembly, compressed air can be blown from both sides to the knitting needles 12, which can play a certain role in fixing the knitting needles 12, and under the action of the internal air pressure, it will also apply a certain outward force to the insert pieces 2, improving the stability of the insert pieces 2.

[0027] Furthermore, as Figures 2-4As shown, the air blowing assembly includes an air inlet hole 21; air grooves 22 are formed on the sides of the first sheet body 13 and the second sheet body 14 away from the groove 15; the air inlet hole 21 is located on the side of the air groove 22, and air inlet holes 21 are formed on both the first sheet body 13 and the second sheet body 14, and the air inlet holes 21 on the first sheet body 13 and the air inlet holes 21 on the second sheet body 14 communicate with each other; a plurality of air outlet holes 23 are formed on the side of the air groove 22; the air outlet holes 23 communicate with the groove 15; an opening is formed at the top of the groove 15; during use, the first sheet body 13 and the second sheet body 14 are stacked to prevent movement, and the groove 15 between two adjacent first sheet bodies 13 forms a moving channel through which the knitting needle 12 can move.

After the adjacent first sheet body 13 and the second sheet body 14 are attached, the two adjacent air grooves 22 are combined into a complete air groove 22, and the opening at the top is used for air outlet. At the same time, due to the outward air outlet, external fibers can be blocked, and the blowing can make a certain gap between the knitting needle 12 and the first sheet body 13 and the second sheet body 14, which is convenient for reducing friction.

[0028] Further, as Figures 2-4 shown, a gas delivery pipe 31 is arranged in the middle of the air inlet hole 21; a through groove 32 is formed at a position corresponding to the air groove 22 on the side of the gas delivery pipe 31; during use, compressed air is delivered through the gas delivery pipe 31 inserted into the air inlet hole 21. During use, the staff can adjust the air intake volume of the air delivery groove 22 by replacing the gas delivery pipe 31 with different opening sizes of the through groove 32.

[0029] Further, as Figures 3-4 shown, a plurality of positioning rods 41 are fixedly connected to the side of the second sheet body 14 close to the first sheet body 13; positioning holes 42 are formed at positions corresponding to the positioning rods 41 on the first sheet body 13; when the first sheet body 13 and the second sheet body 14 are combined, the positioning rods 41 will be inserted into the corresponding positioning holes 42, which can play a certain positioning and fixing role for them, thereby reducing the situation of dislocation.

[0030] Further, as Figures 2-5As shown, a nozzle 51 is slidably connected to the middle of the air outlet 23; the nozzle 51 penetrates through the adjacent first sheet 13 and second sheet 14; an air inlet 52 is formed in the middle of the nozzle 51; the air inlet 52 is communicated with the air groove 22; openings are provided at both ends of the nozzle 51; during use, the air flow in the air groove 22 will enter the air inlet 52 of the nozzle 51 through the air groove 22, and then spray outwards from both ends of the nozzle 51. The nozzle 51 can play a certain role in supporting the tops of the first plate body and the second plate body.

[0031] Further, as Figures 3-4 shown, a clamping groove is formed in the side surface of the groove 15; a rubber plug 61 is slidably connected to the clamping groove in a pluggable manner; a through groove 62 is formed in the middle of the rubber plug 61; the knitting needle 12 passes through the through groove 62 and is slidably connected thereto; during use, the rubber plug 61 is used to play a role in blocking, so as to reduce the problem that the air flow sprays out from the side and affects the fabric, and make the air flow spray out from above the groove 15.

[0033] Further, the openings at both ends of the nozzle 51 are arranged in a conical structure; during use, by arranging the openings at both ends of the nozzle 51 to be conical, the air flow pressure at the air outlet end can be increased.

[0034] Working principle: During use, by means of the cooperation between the toothed mouthpiece 17 and the sinker 16, the knitting needle 12 is fixed, reducing the left-right swaying and elastic deformation of the head of the knitting needle 12 caused by the pulling force of the yarn during the knitting and purling operations, thus avoiding the phenomena of missed stitches and unstable knitting patterns. Moreover, the strength requirement for the insert piece 2 can be reduced, and its thickness can be reduced, thereby facilitating the arrangement of more knitting needles 12, contributing to an increase in the fabric density. At the same time, relying on the blowing component, compressed air can be blown from both sides towards the knitting needles 12, so it can play a certain role in fixing the knitting needles 12. And under the action of the internal air pressure, it will also exert a certain outward force on the insert piece 2, improving the stability of the insert piece 2. The first body 13 and the second body 14 are stacked in this way to prevent movement. The groove 15 between two adjacent first bodies 13 forms a movement channel through which the knitting needle 12 can move. The air inlet holes 21 on the first body 13 and the air inlet holes 21 on the second body 14 are interconnected to form a complete air delivery channel. The air inlet holes 21 at its end are connected to an external air pump. After the adjacent first body 13 and the second body 14 are fitted together, their two adjacent air grooves 22 are combined into a complete air groove 22, and the opening at the top is for air outlet. At the same time, due to the outward air outlet, it can block the entry of external fibers. And relying on the blowing, there can be a certain gap between the knitting needle 12 and the first body 13 and the second body 14, facilitating the reduction of friction. The compressed air is delivered through the air delivery pipe 31 inserted into the air inlet hole 21. During use, the operator can adjust the air intake volume of the air delivery groove 22 by changing the opening size of the different through grooves 32 of the air delivery pipe 31. When the first body 13 and the second body 14 are fitted together, the positioning rod 41 will be inserted into the corresponding positioning hole 42, so it can play a certain role in positioning and fixing, thus reducing the occurrence of misalignment. The air flow in the air groove 22 will enter the air inlet 52 of the air nozzle 51 through the air groove 22, and then be ejected outward from both ends of the air nozzle 51. The air nozzle 51 can play a certain role in supporting the top of the first plate body and the second plate body. The rubber plug 61 is used for plugging to reduce the problem of air flow spraying out from the side and affecting the fabric, so that the air flow is ejected from above the groove 15. By setting the rubber pad, the sealing performance of the fit between the first plate body and the second plate body can be improved, thus enhancing the sealing performance at the joint of the air groove 22 and facilitating the flow of compressed gas in the air groove 22. By setting the openings at both ends of the air nozzle 51 to be conical, the air flow pressure at the air outlet end can be increased.
