Description

Technical Field

[0001] This utility model relates to the field of knitting equipment technology, specifically a computerized flat knitting machine pressing mechanism. Background Technology

[0002] Computerized flat knitting machine is a double-needle plate-latch needle weft knitting machine. Its cam device consists of a set of flat cams. The needle feet can enter the grooves of the cams. By moving the cams, the needles are forced to make regular up-and-down movements in the needle grooves of the needle plate. The movement trajectory of the needles is controlled by the action of the needle hook and the needle tongue, thereby knitting the yarn into a knitted fabric.

[0003] The pressing mechanism of a computerized flat knitting machine is a key component used to control and manage the yarn during the knitting process. The main function of the pressing mechanism is to ensure that the yarn tension is uniform during the knitting process, prevent the yarn from loosening or breaking, and thus ensure the quality and stability of the knitted fabric.

[0004] However, most current pressing mechanisms press the yarn down using pressing blocks. Since the lower surface of the pressing blocks is relatively smooth, the yarn under the pressing blocks is prone to crossing each other, causing the yarns to become tangled, which affects the working stability of the computerized flat knitting machine. Furthermore, the yarn has some fuzz on its surface before weaving, and this fuzz can easily affect the computerized flat knitting machine when it enters the machine.

[0005] Therefore, this utility model provides a crimping mechanism for a computerized flat knitting machine to solve the above problems. Utility Model Content

[0026] 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.

[0027] This utility model provides a crimping mechanism for a computerized flat knitting machine, such as... Figures 1-6 As shown, the crimping mechanism of the computer flat knitting machine includes a machine body 1. Two support plates 2 are fixedly installed on the upper surface of the machine body 1. The two support plates 2 are respectively close to the two sides of the machine body 1. A fixing plate 3 is fixedly installed between the two support plates 2. A needle roller 4 is fixedly installed on the lower surface of the fixing plate 3. A crimping assembly 5 is provided on the side wall of the support plate 2. A limit assembly 6 is provided on the outer surface of the support plate 2.

[0028] The pressure assembly 5 includes a rotating rod 51, a fixed rod 56, and a movable rod 514. Two mounting sleeves 52 are rotatably mounted on the outer surface of the rotating rod 51. The side wall of the mounting sleeve 52 is fixedly connected to the side wall of the support plate 2. Two cams 55 are fixedly mounted on the outer surface of the rotating rod 51. The two cams 55 are located on the outer side of the two mounting sleeves 52 respectively.

[0029] A mounting base 54 is fixedly mounted on the side wall of the mounting sleeve 52. A servo motor 53 is fixedly mounted on the upper surface of the mounting base 54. The output end of the servo motor 53 is fixedly connected to one end of the rotating rod 51.

[0030] A pressure roller 57 is fixedly installed on the outer surface of the fixed rod 56. Several wire grooves 58 are provided on the outer surface of the pressure roller 57. Two sliders 59 are fixedly installed on the outer surface of the fixed rod 56. The two sliders 59 are located at both ends of the pressure roller 57.

[0031] A support spring 510 is fixedly installed on the side wall of the slider 59, and push rods 511 are fixedly installed at both ends of the fixed rod 56. One end of the push rod 511 is in contact with the outer surface of the cam 55.

[0032] Both ends of the movable rod 514 are rotatably mounted with fixed sleeves 512. The side walls of the two fixed sleeves 512 are fixedly connected to the other side walls of the two support plates 2. The outer surface of the movable rod 514 is fixedly mounted with a wire pressing wheel 515. The wire pressing wheel 515 is adapted to the wire groove 58. The inner wall of the fixed sleeve 512 is provided with a sliding groove 513. The outer surface of the slider 59 is slidably connected to the inner wall of the sliding groove 513. One end of the support spring 510 is fixedly connected to the inner side wall of the sliding groove 513.

[0033] Specifically, by setting the yarn pressing component 5, the computerized flat knitting machine automatically presses the yarn during the knitting process, preventing the yarn from moving with the needle. A roller containing the yarn is installed on the needle roller 4. One end of the yarn passes through the middle of the limiting ring 63, and then the other end passes between the pressing roller 57 and the pressing wheel 515. At this point, the yarn corresponds one-to-one with the thread groove on the pressing roller 57. Then, one end of the yarn is placed into the computerized flat knitting machine. When the machine is knitting, the servo motor 53 drives the rotating rod 51 to rotate under the limit of the mounting sleeve 52. At this time, the rotating rod 51 drives the cam 55 to rotate synchronously. When rotated, the push rod 511 is squeezed by the cam 55. At this time, the push rod 511 will drive the fixed rod 56 to move in the slide groove 513 under the limit of the slider 59. Under the action of the support spring 510, the slider 59 will drive the fixed rod 56 to move back and forth in the slide groove 513 with the rotation of the cam 55. When the fixed rod 56 moves back and forth, it will drive the pressing roller 57 to move synchronously. At this time, with the cooperation of the pressing wheel 515, the pressing operation of the yarn is realized. The guide groove 58 can limit the yarn, effectively avoiding the yarn from crossing or tangling during the pressing process, and ensuring the pressing stability of the computer flat knitting machine.

[0034] The limiting component 6 includes a lifting plate 61, with limiting rods 64 fixedly installed at both ends of the lifting plate 61. A limiting groove 7 is provided on the inner wall of the support plate 2. One end of the limiting rod 64 passes through the interior of the limiting groove 7. A fixing spring 65 is fixedly installed on the upper surface of the limiting rod 64. One end of the fixing spring 65 is fixedly connected to the inner wall of the top surface of the limiting groove 7.

[0035] A support rod 62 is fixedly installed on the side wall of the lifting plate 61. A limit ring 63 is fixedly installed at one end of the support rod 62. A cleaning sponge is fixedly installed on the inner surface of the limit ring 63.

[0036] A connecting rod 66 is fixedly installed on the lower surface of the limiting rod 64. One end of the connecting rod 66 is in contact with the upper surface of the top rod 511. A top block 8 is fixedly installed on the upper surface of the top rod 511. The top block 8 is used in conjunction with the connecting rod 66.

[0037] Specifically, by setting the limiting component 6, the yarn is limited during movement, and the yarn surface is also cleaned. After the yarn passes through the middle of the limiting ring 63, the cleaning sponge inside the limiting ring 63 wraps the yarn. During the back-and-forth movement of the top rod 511, the top block 8 is moved synchronously. As the top block 8 moves, it squeezes one end of the connecting rod 66, causing the connecting rod 66 to move upward. This, in turn, drives the lifting plate 61 synchronously through the limiting rod 64. When the lifting plate 61 moves up and down under the action of the fixed spring 65, the lifting plate 61 drives the limiting ring 63 to move up and down synchronously through the support rod 62. When the limiting ring 63 moves up and down, it drives the cleaning sponge to clean the lint and other particles on the outer surface of the yarn. At the same time, the moving speed of the limiting ring 63 is the same as the moving speed of the pressing roller 57. When the pressing roller 57 presses the yarn, the limiting ring 63 moves up; conversely, when the pressing roller 57 does not press the yarn, the limiting ring 63 moves down, which plays a role in adjusting the tension of the yarn.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
