Description

Technical Field

[0001] The invention belongs to the technical field of knitting machinery, in particular to a seamless underwear machine, and more specifically to a multi-color line guide plate of the seamless underwear machine. Background Art

[0002] The underwear machine is a type of circular knitting machine, which makes underwear by weft knitting. Because it is not like traditional cut-out underwear that is made of multiple pieces, there is no connection seam on the underwear, which is called seamless underwear, and is therefore popular with consumers. As a weft knitting machine, the underwear machine also needs a yarn feeding mechanism to provide yarn, so that it can cooperate with the knitting needles to knit; compared with weft knitting machines such as flat knitting machines and sock machines, the underwear machine has more shuttles, so the yarn feeding mechanism needs to have more working positions to obtain a good knitting effect.

[0003] The position of the yarn feeding mechanism is essentially the position of each shuttle relative to the needles; the needles are arranged vertically in a circle, and the shuttle cooperates with the needles on a roughly horizontal plane. The shuttle needs to have more points relative to the needle heads.

[0004] The closest prior art in this field is Chinese patent CN101021028A, which relates to a yarn guide and feeding device for a seamless underwear machine, including an integrated cylinder and a square shuttle plate installed on a disc, a plurality of knitting needles and a grabbing needle for opening the knitting needle tongue located in front of the integrated cylinder and installed on the same disc as the integrated cylinder, and a plurality of yarn adding shuttles for conveying different yarns, including a yarn adding shuttle for face yarn, a yarn adding shuttle for colored yarn, and a yarn adding shuttle for bottom yarn. Each yarn adding shuttle has a plurality of working positions controlled by the integrated cylinder. The yarn adding shuttle for conveying face yarn has five working positions, and the others have two working positions, namely, the original position and the bottom position, of which three are used for conveying bottom yarn and three are used for conveying colored yarn. The integrated cylinder is provided with air passages leading to a plurality of pistons arranged therein, and each piston is used to control the working positions of a plurality of yarn adding shuttles. The square shuttle plate referred to herein is the yarn guide plate involved in the present invention.

[0005] The problem with the yarn guide plate in the prior art is that the shape design is not reasonable enough, and it is difficult to simultaneously meet the working requirements of multiple different shuttles. At the same time, the yarn guide plate must cooperate with the knitting needles, and collisions between them are inevitable, which may damage the needle hooks of the knitting needles. Summary of the invention

[0006] The object of the present invention is to overcome the above-mentioned defects and provide a more reasonable multi-color thread guide plate for a seamless underwear machine.

[0007] The technical solution adopted by the present invention is as follows: a multi-color yarn guide plate of a seamless underwear machine includes a working surface that cooperates with knitting needles, and the knitting needles pass through the working surface from front to back, and a plurality of supporting shuttles and yarn grooves for yarn to pass through are provided on the upper surface of the working surface; it is characterized in that: at the front end of the working surface, its lower surface has a needle tongue needle protection slope; in the middle of the working surface, its lower surface is provided with a loop protection slope; at the rear end of the working surface, its lower surface is provided with a loop protection slope; the needle tongue needle protection slope, the loop protection slope and the loop protection slope are all slopes extending downward and inward; the yarn groove includes a bottom yarn groove, a first surface yarn groove, a second surface yarn groove, and an adding yarn groove, wherein the bottom yarn groove, the first surface yarn groove, and the second surface yarn groove are arranged from back to front between the loop protection slope and the loop protection slope, and the adding yarn groove is arranged between the loop protection slope and the needle tongue needle protection slope.

[0008] Furthermore, the inclination angle between the needle tongue needle guard bevel and the horizontal plane is 20°, the inclination angle between the loop needle guard bevel and the horizontal plane is 20°, and the inclination angle between the loop needle guard bevel and the horizontal plane is 45°.

[0009] A thread blocking boss is provided between the first surface yarn groove and the second surface yarn groove.

[0010] The rear side of the bottom yarn slot is an inclined surface extending backward and upward, and the angle between the inclined surface and the vertical surface is 40 degrees.

[0011] Between the bottom yarn groove and the first surface yarn groove is an inclined plane extending forward and upward, and the included angle with the vertical plane is 70 degrees.

[0012] The second veil groove is a V-shaped groove with an angle of 20°.

[0013] The rear side of the yarn adding groove is an inclined surface extending backward and upward, and the angle between the inclined surface and the vertical surface is 60°.

[0014] The present invention is designed with multiple needle protection bevels to protect the knitting needles in different knitting actions, so that the knitting needles can enter the matching position with the shuttle according to the bevels, thereby protecting the needle hook tongue. Different yarn grooves can be used for different shuttles, and the angles of each bevel are accurately calculated to guide the required yarn to the set position without interference between the yarns of each route.

DETAILED DESCRIPTION

[0019] See attached picture. Figure 1 Figure 2 The direction closer to the reader is the working surface cooperating with the knitting needles, and the knitting needles cooperate with it from right to left, so the left side in the figure is the rear and the right side is the front; accordingly, the direction closer to the working surface is the outside, and the direction closer to the mounting seat is the inside.

[0020] The knitting needles pass through the working surface from front to back, and a number of supporting shuttles and yarn grooves for the yarn to pass through are arranged on the upper surface of the working surface. From back to front, there are a looping needle protection bevel 2, a bottom yarn groove 3, a first yarn groove 4, a second yarn groove 6, a looping needle protection bevel 7, and a yarn adding groove 8. The front end is a needle latch needle protection bevel 9, and a thread blocking boss 5 is provided between the first yarn groove and the second yarn groove.

[0021] The above functional areas, such as Figure 3 As shown, at the front end of the working surface, its lower surface is provided with a needle tongue needle protection bevel 9; in the middle of the working surface, its lower surface is provided with a loop needle protection bevel 7; at the rear end of the working surface, its lower surface is provided with a loop needle protection bevel 2; the needle tongue needle protection bevel, the loop needle protection bevel and the loop needle protection bevel are all bevels extending downward and inward.

[0022] Among them: the inclination angle of the needle tongue needle guard slope 9 and the horizontal plane is 20°, the inclination angle of the loop needle guard slope 7 and the horizontal plane is 20°, and the inclination angle of the loop needle guard slope 2 and the horizontal plane is 45°.

[0023] like Figure 3 As shown, the yarn groove includes a bottom yarn groove 3, a first surface yarn groove 4, a second surface yarn groove 6, and an added yarn groove 8, wherein the bottom yarn groove, the first surface yarn groove 4, and the second surface yarn groove 6 are arranged from back to front between the loop forming needle guard bevel 2 and the loop gathering needle guard bevel 7, and the added yarn groove 8 is arranged between the loop gathering needle guard bevel 7 and the needle tongue needle guard bevel 9.

[0024] The angle between the left slope of the bottom yarn groove 3 and the vertical plane is 40°, the angle between the right slope of the bottom yarn groove 3 and the vertical plane is 70°, the second surface yarn groove 6 is a V-shaped groove with an angle of 20°, and the angle between the left slope of the added yarn groove 8 and the vertical plane is 60°.

[0025] The yarn guide plate 1 is installed on the yarn guide plate mounting seat 10, three bottom yarn shuttles 11 correspond to the bottom yarn groove 3, two first-level face yarn shuttles 12 correspond to the first face yarn groove 4, one second-level face yarn shuttle corresponds to the second face yarn groove 6, and two added yarn shuttles 14 correspond to the added yarn groove 8, guiding the respective yarns to pass through in preparation for knitting with knitting needles.

[0026] Through the above design, when the knitting needle performs looping or gathering action, it enters the matching position with the shuttle along the looping needle guard bevel or the gathering needle guard bevel respectively, thereby protecting the needle hook from impact; the needle latch needle guard bevel 9 ensures that the needle latch is not flipped up during the two actions, so that the needle hook can smoothly hook the new yarn.

[0027] The shuttles of various yarns are led out from different yarn grooves respectively. Through specific angle design, each yarn can reach the appropriate point without interfering with each other.
