Description

Technical Field

[0001] This utility model relates to the field of computerized flat knitting machine technology, and in particular to a pressing mechanism for a computerized flat knitting machine with good loop forming effect. Background Technology

[0002] A computerized flat knitting machine is a double-needle plate and latch needle weft knitting machine. Its cam mechanism is like a set of planar cams. The needle feet can enter the grooves of the cams. Moving the cams forces the needles to make regular up-and-down movements in the needle grooves of the needle plate. Through the action of the needle hook and the needle latch, the yarn can be knitted into a fabric. In order to improve the loop formation effect of the yarn, a pressing mechanism is required when the computerized flat knitting machine is knitting.

[0003] A search of the Chinese patent "A Computerized Flat Knitting Machine Pressing Mechanism" (publication number CN221854943U) reveals that this patent uses a groove on the surface of a guide roller to limit the movement of the yarn before it is pressed down, thus preventing the yarn from tangling. A limiting rod is elastically installed below the guide roller, and this limiting rod is mounted via sliding blocks on both sides. These two sliding blocks, through a positioning rod and a spring, allow a sponge outside the limiting rod to elastically contact the lower surface of the guide roller. Therefore, when the yarn passes through the groove, the sponge cleans the surface dust and provides a limiting function. This device uses a pressure roller and a positioning roller to press and limit the yarn, and the sliding blocks, positioning rod, and spring work together to make the sponge contact the guide roller to clean the yarn surface dust. However, the control of yarn tension during the knitting process of the computerized flat knitting machine is not ideal, making it inconvenient to control the yarn tension during knitting, resulting in an unsatisfactory yarn looping effect.

[0004] Therefore, a computerized flat knitting machine pressing mechanism with good loop forming effect is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a computerized flat knitting machine pressing mechanism with good loop-forming effect to solve the above-mentioned problems, thereby improving the problem of inconvenient control of yarn tension during weaving.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a computer flat knitting machine pressing mechanism with good loop-forming effect, comprising a base plate, two conveying rollers rotatably connected to the top of the base plate; a pressing mechanism, which can control the yarn tension during computer flat knitting, is disposed at the top of the base plate; wherein, the pressing mechanism includes a plurality of evenly distributed limiting grooves formed on the outer wall of the conveying rollers, a pressing roller is rotatably connected to the top of the base plate, the pressing roller is disposed between two of the limiting grooves, and limiting components are provided at both ends of the pressing roller.

[0007] Preferably, the pressing mechanism further includes sliders rotatably connected to both ends of the pressing roller. Mounting blocks are slidably connected to both sides of the inner wall of the base plate. The sliders are slidably connected to the inner walls of the mounting blocks. Two compression springs are provided on the inner walls of the mounting blocks. The sliders are positioned between the two compression springs. The pressing roller can self-adjust by moving when pressing the yarn through the cooperation of the sliders at both ends and the compression springs, preventing excessive tension in the device and maintaining tension in the yarn during weaving, thereby improving the looping effect.

[0008] Preferably, a pointer is fixedly connected to one side of one of the sliders, one end of which penetrates through the outer wall particles of the base plate. A scale that cooperates with the pointer is fixedly connected to the middle of one side of the base plate. When the lower pressure roller moves downward, it can drive the pointer to move with it and make precise adjustments in cooperation with the scale. The pointer is aligned with the center of the lower pressure roller.

[0009] Preferably, both the mounting block and the base plate have a sliding groove on one side, and the inner wall of the sliding groove is slidably connected to the pointer, allowing the pointer to slide up and down through the sliding groove.

[0010] Preferably, a lead screw is rotatably connected to the other side of the base plate. One end of the lead screw passes through the base plate and is threadedly connected to another mounting block. The lead screw and the other mounting block cooperate to adjust the downward pressing position of the lower pressure roller.

[0011] Preferably, the limiting component includes two mounting plates fixedly connected to the top of the base plate. The two mounting plates are respectively disposed on one side of the two conveying rollers. The top of the mounting plate is provided with a plurality of evenly distributed limiting holes. When the conveying rollers limit the conveying of the yarn, the limiting holes on the mounting plate prevent the yarn from getting tangled together.

[0012] Preferably, the inner wall of the limiting hole is rotatably connected to several evenly distributed rotating rods, which are aligned with the limiting groove. The rotating rods in the through hole can transport the yarn and prevent yarn wear.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a pressing mechanism, the yarn is conveyed through the conveyor rollers during the knitting process of the computerized flat knitting machine. The limiting grooves on the conveyor rollers can limit the yarn movement. Rotating the screw and connecting it to another mounting block via a threaded connection drives the pressing roller downwards to adjust the yarn tension and improve the loop-forming effect of the computerized flat knitting machine. The pressing roller can move up and down through the cooperation of the sliders at both ends and the compression springs, allowing for self-adjustment according to the needs of the yarn. When the pressing roller moves downwards, it drives the pointer and the scale to cooperate to control the pressing position of the pressing roller. The center of the pointer is aligned with the center of the pressing roller, which can control the yarn tension and improve the loop-forming effect of the computerized flat knitting machine.

[0015] By setting a limiting component, when the yarn is braided into loops, the conveying roller can limit the yarn through the limiting hole on one side of the mounting plate to prevent the yarn from getting tangled together during braiding. The upper and lower ends of the limiting hole are both arc-shaped, and several rotating rods inside the limiting hole can guide and convey the yarn, reducing wear on the yarn during conveying. This can limit the yarn and improve the stability and consistency of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4 As shown, a computer flat knitting machine pressing mechanism with good loop forming effect includes a base plate 1, with two conveying rollers 2 rotatably connected to the top of the base plate 1; a pressing mechanism 3, which can control the yarn tension during the computer flat knitting machine, is set at the top of the base plate 1; wherein, the pressing mechanism 3 includes several evenly distributed limiting grooves 301 opened on the outer wall of the conveying rollers 2, and a pressing roller 302 is rotatably connected to the top of the base plate 1, the pressing roller 302 is set between two limiting grooves 301, and both ends of the pressing roller 302 are provided with limiting components 310.

[0023] like Figure 2 and Figure 3 As shown, the pressing mechanism 3 also includes sliders 303 rotatably connected to both ends of the pressing roller 302. Mounting blocks 304 are slidably connected to both sides of the inner wall of the base plate 1. Slider 303 is slidably connected to the inner wall of the mounting blocks 304. Two compression springs 305 are provided on the inner wall of the mounting blocks 304. Slider 303 is positioned between the two compression springs 305. A pointer 306 is fixedly connected to one side of one of the sliders 303. One end of the pointer 306 penetrates to the outer wall of the base plate 1. A scale 307 cooperating with the pointer 306 is fixedly connected to the middle of one side of the base plate 1. Slide grooves 308 are provided on both the mounting blocks 304 and one side of the base plate 1. The inner wall of the slide groove 308 is slidably connected to the pointer 306. The base plate 1... On the other side, a lead screw 309 is rotatably connected. One end of the lead screw 309 passes through the base plate 1 and is threadedly connected to another mounting block 304. When the yarn is braided into loops, the lead screw 309 and the other mounting block 304 threadedly drive the lower pressure roller 302 to move downward and press down on the yarn. The lower pressure roller 302 is self-adjusted by the sliders 303 at both ends and the compression springs 305 to prevent excessive yarn pressure. The compression springs 305 at the upper and lower ends of the sliders 303 allow them to be adjusted up and down. The pointer 306 moves downward with the lower pressure roller 302 and, in conjunction with the scale 307, precisely controls the position of the lower pressure roller 302. This allows for control of the yarn tension and improves the looping effect of the computerized flat knitting machine.

[0024] like Figure 4 As shown, the limiting assembly 310 includes two mounting plates 3101 fixedly connected to the top of the base plate 1. The two mounting plates 3101 are respectively disposed on one side of the two conveying rollers 2. The top of the mounting plate 3101 is provided with a number of evenly distributed limiting holes 3102. The inner wall of the limiting hole 3102 is rotatably connected with a number of evenly distributed rotating rods 3103. The rotating rods 3103 are aligned with the limiting groove 301. When the yarn is braided into a loop, the alignment of the limiting hole 3102 on the mounting plate 3101 with the limiting groove 301 can convey the yarn on the conveying roller 2 and prevent the yarn from tangling. The rotating rods 3103 on the inner wall of the limiting hole 3102 can guide and convey the yarn and limit the yarn, thereby improving the stability of the device.

[0025] In use, one end of the yarn passes through the limiting groove 301 at the top of one of the conveying rollers 2, then through the bottom end of the lower pressure roller 302, and then through the limiting groove 301 at the top of the other conveying roller 2 for limiting conveying. The screw 309 is manually rotated and threaded to another mounting block 304 to drive the lower pressure roller 302 to move downward and press down on the yarn, thereby controlling the yarn tension. When the lower pressure roller 302 moves downward, it drives the pointer 306 to move accordingly and cooperates with the scale 307 to control the position of the lower pressure roller 302. The lower pressure roller 302, through the slider 303 and the compression spring 305, can self-adjust the tension according to the yarn conveying situation. When conveying the yarn, one end of the yarn passes through the limiting hole 3102 on the mounting plate 3101 and cooperates with the rotating rod 3103 to limit the conveying of the yarn.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
