A yarn guiding mechanism for a computerized flat knitting machine

Abstract

This utility model discloses a yarn guiding mechanism for a computerized flat knitting machine, including a mounting base and multiple guide grooves. The mounting base is equipped with a mounting assembly. The mounting assembly includes multiple rotating grooves. A rotating bolt is located at the bottom of each guide groove, a gear groove is located at the bottom of each rotating groove, and a mounting groove is located at the bottom of each gear groove. A limit tube is located at the bottom of the rotating bolt, and a circular plate is movably mounted inside each mounting groove. In this utility model, a pulling rod drives the guide groove to rotate. When the guide groove rotates to a suitable angle, the pulling rod is released, and a spring pushes the circular plate, causing the mounting gear to insert into the gear groove. This locks the limit rod, preventing it from rotating, thus preventing the upper guide groove from rotating. By adjusting the angles of different guide grooves and guide wheels, the system can meet the requirements for complex patterns where multiple yarns need to enter the knitting area at different angles.

Description

Technical Field

[0001] This utility model relates to the field of yarn guiding technology for computerized flat knitting machines, specifically a yarn guiding mechanism for computerized flat knitting machines. Background Technology

[0002] The yarn guiding mechanism in a computerized flat knitting machine is a crucial step in the machine's operation, precisely guiding the yarn to the knitting area. Its core function is to control the yarn's direction, tension, and feed position according to the pre-set patterns and knitting instructions in the computer program. This ensures the yarn accurately enters the working range of the needles, working in conjunction to complete knitting actions such as loop formation and connection. The precision of the yarn guiding system directly affects the fabric's smoothness, pattern clarity, and knitting efficiency. Under computer control, the yarn guiding mechanism can achieve rapid switching of multi-colored yarns and precise alignment of complex patterns. It is a vital guarantee for the automation and intelligent knitting of computerized flat knitting machines and is widely used in the industrial production of sweaters, knitted fabrics, and other products.

[0003] The existing Chinese patent announcement number CN222935631U, entitled "A Directional Yarn Guide Mechanism for a Computerized Flat Knitting Machine," explicitly states in its abstract that it "includes a mounting base, a horizontal mounting strip fixedly mounted on the top of the mounting base, a telescopic mounting block mounted on the side wall of the horizontal mounting strip, the telescopic mounting block being rotatably connected to the horizontal mounting strip via a first rotating seat, a horizontal limiting groove being provided on the mounting base, a horizontal movement pushing component being installed in the horizontal limiting groove, the other end of the telescopic mounting block being rotatably connected to the horizontal movement pushing component via a second rotating seat, and a protective yarn guide component with limiting function being installed on the telescopic mounting block."

[0004] Existing technology uses a lateral movement push component to allow the telescopic mounting block to adjust the angle of the protective yarn guide component with a limiting function, which can meet the guiding use of yarns with different directions of yarn travel and is more flexible and convenient to use. However, when adjusting the angle of the yarn guide component, all guide wheels are adjusted at the same time and in the same direction. This means that in the actual weaving process, when encountering complex patterns that require multiple yarns to enter the weaving area at different angles, the existing structure is difficult to meet the differentiated yarn guiding needs. Utility Model Content

[0005] The purpose of this invention is to provide a yarn guiding mechanism for a computerized flat knitting machine, in order to solve the problem mentioned in the background art that the existing structure is unable to meet the differentiated yarn guiding requirements when encountering complex patterns that require multiple yarns to enter the knitting area at different angles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A yarn guiding mechanism for a computerized flat knitting machine includes a mounting base and multiple guide grooves, wherein the mounting base is provided with mounting components;

[0008] The mounting assembly includes multiple rotating slots, a rotating bolt is provided at the bottom of the guide slot, a gear slot is provided at the bottom of the rotating slot, an installation slot is provided at the bottom of the gear slot, a limit tube is provided at the bottom of the rotating bolt, and a circular plate is movably arranged inside the installation slot.

[0009] In a preferred embodiment of this utility model, two guide wheels are rotatably arranged inside the guide groove, and the rotating bolt is rotatably installed in the rotating groove.

[0010] In a preferred embodiment of the present invention, a mounting gear is provided on the top of the circular plate, and the mounting gear is installed and removed in a gear groove.

[0011] In a preferred embodiment of this utility model, a limiting rod is provided on the top of the mounting gear, and the limiting rod is slidably connected to the limiting tube.

[0012] In a preferred embodiment of this utility model, a spring is provided at the bottom of the circular plate, and a pull rod is provided inside the spring.

[0013] In a preferred embodiment of this utility model, a rotating plate is rotatably provided at the bottom of the mounting groove, and the bottom of the spring is connected to the rotating plate.

[0014] In a preferred embodiment of the present invention, the pulling rod is slidably connected to the rotating plate, and the pulling rod extends to the bottom outer side of the rotating plate.

[0015] In a preferred embodiment of this utility model, support seats are provided on both sides of the bottom of the mounting base.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0017] Beneficial effects: The yarn passes between two guide wheels, which guide the yarn. Pulling the circular plate downwards with the pull rod disassembles the mounting gear in the gear slot, while the limiting rod remains in the limiting tube. Rotating the pull rod then rotates the upper limiting rod and the rotating bolt, thus rotating the guide groove. When the guide groove reaches the appropriate angle, releasing the pull rod allows the spring to push the circular plate, causing the mounting gear to insert into the gear slot. This locks the limiting rod, preventing it from rotating, and thus the upper guide groove cannot rotate. By adjusting the angles of different guide grooves and guide wheels, complex patterns requiring multiple yarns to enter the weaving area at different angles can be accommodated.

[0018] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-4This utility model discloses a yarn guiding mechanism for a computerized flat knitting machine, comprising a mounting base 1 and multiple guide grooves 2. The mounting base 1 is used to install the overall structure, and the multiple guide grooves 2 are used to install the guiding structure. Two guide wheels 21 are rotatably arranged inside the guide grooves 2, that is, the yarn is guided by the two guide wheels 21 and the yarn passes between the two guide wheels 21. Support seats 4 are provided on both sides of the bottom of the mounting base 1, and the support seats 4 are provided with mounting holes, that is, the overall structure is supported by the support seats 4, and the structure can be fixed by the mounting holes, which is a conventional technical means for those skilled in the art.

[0027] The mounting base 1 is provided with a mounting component, which includes multiple rotating grooves 11. A rotating bolt 22 is provided at the bottom of the guide groove 2. The rotating bolt 22 is locked in the rotating groove 11 and rotates. That is, by rotating different rotating bolts 22 in the rotating groove 11, the angles of different guide grooves 2 and guide wheels 21 can be adjusted respectively. When encountering complex patterns that require multiple yarns to enter the weaving area at different angles, the requirements can be met.

[0028] A gear groove 12 is provided at the bottom of the rotating groove 11, and an installation groove 13 is provided at the bottom of the gear groove 12. A limit tube 23 is provided at the bottom of the rotating bolt 22. A circular plate 3 is movably installed inside the installation groove 13. The circular plate 3 rotates and slides up and down inside the installation groove 13. An installation gear 31 is provided at the top of the circular plate 3. The installation gear 31 is installed and removed in the gear groove 12. The shape of the installation gear 31 can be completely embedded in the gear groove 12. A limit rod 32 is provided at the top of the installation gear 31. The limit rod 32 is slidably connected to the limit tube 23. The limit rod 32 is always in the limit tube 23. Through structural restriction, the limit rod 32 cannot slide out of the limit tube 23. A spring 33 is provided at the bottom of the circular plate 3. A rotating plate 14 is rotatably installed at the bottom of the installation groove 13. The rotating plate 14 is locked at the bottom of the installation groove 13 and rotates. The bottom of the spring 33 is connected to the rotating plate 14. The spring 33 is kept pushing upward, so that the installation gear 31 is inserted into the gear groove 12. The thrust of the spring 33 is set to 5-8N. A pull rod 34 is provided inside the spring 33. The top of the pull rod 34 is connected to the circular plate 3. The overall weight of the circular plate 3, the mounting gear 31, the limiting rod 32, and the pull rod 34 is set to 400-600 grams. The pull rod 34 is slidably connected to the rotating plate 14 and extends to the bottom of the outer side of the rotating plate 14. That is, by pulling the circular plate 3 downward by the pull rod 34, the mounting gear 31 is disassembled in the gear groove 12. The limiting rod 32 is always in the limiting tube 23. At this time, by rotating the pull rod 34, the upper limiting rod 32 and the rotating bolt 22 are rotated, that is, the guide groove 2 is rotated. When the guide groove 2 is rotated to a suitable angle, the pull rod 34 is released. At this time, the circular plate 3 is pushed by the spring 33, so that the mounting gear 31 is inserted into the gear groove 12. At this time, the limiting rod 32 is locked and cannot be rotated, so the upper guide groove 2 cannot be rotated. Even if the mounting gear 31 cannot be inserted into the gear groove 12, it only needs to be rotated slightly.

[0029] The working principle of this utility model is as follows: the yarn passes between two guide wheels 21, which guide the yarn. The pull rod 34 pulls the circular plate 3 downward, causing the mounting gear 31 to disassemble in the gear groove 12. The limiting rod 32 is always in the limiting tube 23. At this time, by rotating the pull rod 34, the upper limiting rod 32 and the rotating bolt 22 are rotated, which drives the guide groove 2 to rotate. When the guide groove 2 rotates to a suitable angle, the pull rod 34 is released. At this time, the spring 33 pushes the circular plate 3, causing the mounting gear 31 to insert into the gear groove 12. This locks the limiting rod 32, preventing it from rotating, and thus the upper guide groove 2 cannot rotate. By adjusting the angles of different guide grooves 2 and guide wheels 21, the requirements can be met when encountering complex patterns that require multiple yarns to enter the weaving area at different angles.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
