Description

Technical Field

[0001] This utility model relates to the field of yarn feeding technology for knitting machines, specifically a yarn feeding structure for knitting machines. Background Technology

[0002] Knitting is the process of using knitting needles to hook various raw materials and types of yarn into loops, and then connecting them to form knitted fabrics. Knitted fabrics are soft, have good wrinkle resistance and breathability, and have great extensibility and elasticity, making them comfortable to wear. In addition to clothing and decoration, knitted products can also be used in industry, agriculture, medical and health care, and national defense. Knitting is divided into two categories: hand knitting and machine knitting. Hand knitting uses knitting needles, has a long history, exquisite techniques, and flexible and varied patterns, and has been widely spread and developed in folk culture.

[0003] For example, patent document CN 217809902 U discloses a flexible yarn feeding structure for a computerized jacquard knitting machine, including a worktable. The top of the worktable has a mounting groove, and a mounting base is slidably connected within the groove. The top of the mounting base extends above the worktable and is fitted with an electric push rod. A support platform is mounted on the top of the electric push rod, and a rotary motor is mounted at the bottom of the support platform. A mounting frame is connected to one side of the support platform, and a rotating wheel is rotatably connected to the mounting frame. A yarn feeding wheel located on one side of the rotating wheel is rotatably mounted on the mounting frame. This utility model, through a series of structural features, facilitates the installation and disassembly of the yarn feeder, thereby simplifying its maintenance and cleaning. Furthermore, the height of the yarn feeder can be adjusted according to the operator's height, saving operation time, making operation more convenient, improving work efficiency, and meeting the user's needs.

[0004] However, when this structure is used for actual yarn feeding in knitting machines, due to its own structural limitations, it cannot perform more suitable pulling and limiting operations on the yarn fed by the knitting machine. This results in the yarn not receiving stable buffering during the pulling process, which easily leads to breakage and affects the normal knitting processing of the equipment. At the same time, the equipment cannot perform more uniform feeding and distributing operations for yarn feeding in knitting machines, which cannot meet the daily use needs. Therefore, it is urgent to design a yarn feeding structure for knitting machines to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a yarn feeding structure for knitting machines, in order to solve the problem mentioned in the background art that, due to the limitations of its own structure, the existing structure cannot perform a more suitable pulling and limiting operation on the yarn fed by the knitting machine when it is actually used for yarn feeding in knitting machines. This results in the yarn not being able to get stable buffering during the pulling process, which easily leads to breakage and affects the normal knitting processing of the equipment. At the same time, the equipment cannot perform a more uniform feeding and distributing operation for yarn feeding in knitting machines, and cannot meet the daily use needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a yarn feeding structure for a knitting machine, comprising an annular air equalizer, wherein a threading groove is provided inside the annular air equalizer, a threaded annular groove is provided on the front side of the threading groove, a yarn separating component is provided on the front side of the annular air equalizer, and a yarn inlet component is provided on the back side of the annular air equalizer. The splitter assembly includes a cable tray, the front of which is movably connected to the cable tray, and the inside of which is movably connected to the cable tray inner seat. The inlet assembly includes a buffer seat, the back of the annular air distribution seat is fixedly connected to the buffer seat, the back of the buffer seat is fixedly connected to the inlet cover, and one end of the inlet cover is fixedly connected to the inlet seat.

[0007] Preferably, the front of the buffer seat is provided with a buffer airbag, and the inner wall of the buffer airbag is provided with a buffer liner.

[0008] Preferably, the front side of the inner connector is uniformly provided with connector grooves, and a positioning rubber ring is provided between one end of the cable sleeve and the inner connector.

[0009] Preferably, a threaded ring seat is fixedly connected to the back of the cable holder.

[0010] Preferably, the upper and lower ends of the annular gas equalization seat are provided with gas control seats, and the gas control seats are provided with gas control pumps inside.

[0011] Preferably, the inner wall of the annular gas equalizer is provided with telescopic airbags at the four corners, and one end of the telescopic airbag is provided with a buffer top seat.

[0012] Preferably, the annular gas equalizing seat is connected to the cable sleeve seat and the buffer seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This knitting machine uses a yarn feeding structure with a ring-shaped air leveling seat, threading groove, threaded ring groove, yarn guide sleeve, yarn divider inner seat, buffer seat, air control seat, air control pump, telescopic airbag, and buffer top seat. This allows the equipment to perform buffering and protection operations more suited to the yarn feeding structure of the knitting machine. In actual use, the operator first inserts the yarn along the buffer seat into the center of the ring-shaped air leveling seat, and then passes it out from the yarn guide sleeve and yarn divider inner seat on the front of the ring-shaped air leveling seat, thus completing the initial quick assembly of the yarn. At the same time, the air control pump inside the air control seats at both ends of the ring-shaped air leveling seat can be activated, which will drive the telescopic airbag inside the four corners of the inner wall of the ring-shaped air leveling seat to adapt and abut the buffer top seat at one end to the center of the yarn. The center adaptation and positioning abutment operation is performed from the four corners of the yarn side. When abnormal pulling occurs during the yarn feeding process of the knitting machine, the yarn can also receive appropriate buffering and protection, demonstrating the practicality of the equipment design.

[0014] This knitting machine utilizes a yarn feeding structure that, through the inclusion of a ring-shaped air distribution seat, a yarn separating inner seat, a buffer seat, a yarn inlet cover, a yarn inlet seat, a buffer airbag, a buffer inner liner, a yarn separating groove, a positioning rubber ring, and a threaded ring seat, further enhances the overall performance of the equipment. During daily use, operators can screw the yarn guide sleeve onto the threaded ring seat on the back of the yarn guide sleeve at the threaded ring groove on the front of the yarn guide groove. Then, the yarn separating groove of the yarn separating inner seat inside the yarn guide sleeve allows for proper separation and yarn arrangement. The yarn guide sleeve and the yarn separating inner seat are connected and positioned by the positioning rubber ring, facilitating quick disassembly and maintenance. Simultaneously, the buffer seat inside the ring-shaped air distribution seat allows for simultaneous yarn guiding via the yarn inlet seat and buffer airbag on the back, followed by a pulling and buffering operation through the internal buffer airbag and buffer inner liner, protecting the yarn and demonstrating the comprehensive design of the equipment.
