Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitting machine core technology, and more specifically, to a knitting machine core component with a lint removal structure. Background Technology
[0002] Circular knitting machines play a crucial role in the textile industry, producing various knitted fabrics commonly found in our daily lives. Whether it's T-shirts, sweatshirts, shirts, or household towels, curtains, and bedding, the exquisite patterns such as jacquard, ribbing, and knitted crochet designs on them all rely on the meticulous craftsmanship of circular knitting machines. The heart of a knitting machine usually refers to the knitting mechanism, the core component of a circular knitting machine. It mainly consists of a cylinder, needles, cams, cam seats, and sinkers. These components work together to control the up-and-down movement of the needles, completing the entire process of knitting yarn into fabric. However, knitted yarns contain loose fibers. Failure to remove these fibers affects the knitting effect and can even damage or jam the machine. Therefore, we have proposed a knitting machine heart component with a fiber removal structure. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a core component of a knitting machine with a lint removal structure.
[0004] To solve the above problems, the present invention adopts the following technical solution:
[0005] A knitting machine core component with a lint removal structure includes a knitting mechanism base. Multiple triangular seats are provided on the top surface of the knitting mechanism base. Mounting seats are installed on the outer sides of each of the triangular seats. Connecting seats are fixedly connected to the outer sides of each mounting seat. A collection box is fixedly connected to the end of each connecting seat. A lint-absorbing steel pipe is fixedly sleeved on the top of each collection box. A cleaning hopper is fixedly connected to the top of each lint-absorbing steel pipe. Multiple cleaning mechanisms are provided on the cleaning hopper. An air pump is fixedly installed on the end face of the collection box. The input end of the air pump extends into the inner cavity of the collection box. A filter screen is fixedly sleeved within the inner cavity of the collection box.
[0006] As a preferred embodiment of this utility model, the cleaning mechanism includes a rotating rod rotatably connected to the inner cavity of the cleaning bucket and a servo motor fixedly installed on the outer side of the cleaning bucket. The output shaft of the servo motor is connected to the end of the rotating rod through a coupling, and a brush roller is fixedly sleeved on the outer side of the rotating rod.
[0007] As a preferred embodiment of this utility model, the outer side of the triangular seat is provided with a screw hole, the mounting base is provided with a mounting hole, a fastening bolt is fitted on the mounting hole, and the end of the fastening bolt is threaded into the inner cavity of the screw hole.
[0008] As a preferred embodiment of this utility model, the outer side of the collection box is hinged with a sealing door, and the inner side of the sealing door is in contact with the side of the filter screen.
[0009] In a preferred embodiment of this utility model, a front guide roller is rotatably connected to one end of the cleaning bucket, and a rear guide roller is rotatably connected to the other end of the cleaning bucket.
[0010] In a preferred embodiment of this utility model, the two ends of the front guide roller and the rear guide roller are respectively attached to the inner wall of the cleaning hopper.
[0011] The advantages of this utility model are:
[0012] In this invention, the yarn passes through multiple brush rollers. A servo motor drives a rotating rod and brush rollers to rotate, and the brush rollers sweep away the loose lint from the yarn. In addition, an air pump generates suction through the suction pipe and cleaning bucket, which draws the loose lint into the inner cavity of the collection box. A filter screen traps the loose lint in the inner cavity of the collection box, thus achieving the function of cleaning loose lint from the yarn. This ensures the smooth operation of the knitting machine's core component and improves the practicality of the knitting machine's core component with a loose lint cleaning structure.

[0025] In this embodiment, the air pump 9 and servo motor 12 are controlled by the controller of the knitting machine, and the air pump 9 and servo motor 12 are powered by the power cord of the peripheral device.
[0026] For details, please refer to Figure 1 and Figure 4The cleaning mechanism 8 includes a rotating rod 13 rotatably connected to the inner cavity of the cleaning bucket 7 and a servo motor 12 fixedly installed on the outside of the cleaning bucket 7. The output shaft of the servo motor 12 is connected to the end of the rotating rod 13 through a coupling. A brush roller 14 is fixedly sleeved on the outside of the rotating rod 13.
[0027] In this embodiment, multiple cleaning mechanisms 8 are arranged intermittently in the upper and lower parts so that the loose hairs on the yarn can be sucked away by the suction of the lint-absorbing steel pipe 6 after being cleaned down.
[0028] For details, please refer to Figures 2 to 5 The outer side of the triangular seat 2 is provided with a screw hole 19, and the mounting seat 3 is provided with a mounting hole 17. A fastening bolt 18 is fitted on the mounting hole 17, and the end of the fastening bolt 18 is threaded into the inner cavity of the screw hole 19.
[0029] In this embodiment, the mounting base 3 is installed on the triangular base 2 by the cooperation of the mounting hole 17, the fastening bolt 18 and the screw hole 19.
[0030] For details, please refer to Figure 3 and Figure 5 A sealing door 11 is hinged to the outside of the collection box 5, and the inner side of the sealing door 11 is in contact with the side of the filter screen 10.
[0031] In this embodiment, the floating hair collected inside the collection box 5 is cleaned by opening the sealing door 11.
[0032] For details, please refer to Figure 3 One end of the cleaning bucket 7 is rotatably connected to a front guide roller 15, and the other end of the cleaning bucket 7 is rotatably connected to a rear guide roller 16.
[0033] In this embodiment, the front guide roller 15 is used to guide the yarn released by the yarn feeding mechanism, and the rear guide roller 16 is used to guide the yarn after the floating hair is cleaned, so that the yarn is supplied to the weaving mechanism.
