[0002] A jacquard knitting machine is a device that can knit fabrics with complex patterns for outerwear and decorative items. The yarn spool of a jacquard knitting machine refers to the component used to store and supply yarn. In a jacquard knitting machine, the function of the knitting yarn spool is to provide the yarn required for the knitting process and ensure a continuous supply of yarn during production.

[0003] In existing jacquard knitting machines, the yarn spools are used to store and supply yarn. When a part of the spool is damaged, because the spool is a whole structure, it is impossible to replace the part of the spool itself, thus rendering the entire spool unusable. At the same time, it is inconvenient to remove the yarn wound on the spool and store it separately. To address this, this utility model proposes a new type of yarn spool for jacquard knitting machines. Utility Model Content

[0004] The purpose of this utility model is to provide a yarn spool for a jacquard knitting machine to solve the problem mentioned in the background art that the yarn spool of a jacquard knitting machine is an integral structure, and cannot be replaced individually when the yarn spool is partially damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bobbin for a jacquard knitting machine, comprising multiple bobbin assemblies installed inside the jacquard knitting machine. Each bobbin assembly consists of a limiting seat, a vertical rod, and a shaft. The limiting seat is located at the top of the vertical rod, and the shaft is located on the side of the vertical rod. The top of the shaft is engaged with the inner side of the limiting seat, and the bottom of the shaft is installed inside the jacquard knitting machine. A bobbin is sleeved on the surface of the shaft. The bobbin consists of a bobbin body and symmetrically arranged end caps. The symmetrically arranged end caps are all located at both ends of the bobbin body, and a locking mechanism is provided at the connection points between the symmetrically arranged end caps and both ends of the bobbin body.

[0006] Preferably, the end cross-sectional dimensions of the cylinder are the same as the end cross-sectional dimensions of the end cap.

[0007] Preferably, the cylinder is a hollow cylindrical structure.

[0008] Preferably, the locking mechanism consists of a locking groove, a locking block, and a locking assembly. The cylinder is opened at the bottom end of the end cap, the locking block is disposed inside the locking groove, the bottom end of the locking block is fixed to the end of the cylinder, and the locking assembly is disposed between the outer side of the locking block and the inner side of the locking groove.

[0009] Preferably, the card block has a hollow cylindrical structure, and the top edge of the card block has an arc-shaped structure.

[0010] Preferably, the engaging assembly consists of a limiting groove, a spring block, and a movable cavity. The movable cavity is located on the outside of the locking block, the limiting groove is located on the outside of the end cap, the limiting groove and the locking groove are in communication, the spring block is located on the inside of the movable cavity and the inside of the limiting groove, and the bottom end of the spring block is fixed to the bottom end of the movable cavity.

[0011] Preferably, the side cross-section of the spring block has an L-shaped structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The design of the detachable bobbin improves upon the previous jacquard knitting machine operation, where the bobbin used for storing and supplying yarn was a single unit and difficult to disassemble and replace when it was partially damaged. By making the bobbin detachable, partial replacement can be performed as needed when the bobbin is partially damaged. Furthermore, since the bobbin and end cap are assembled by a snap-fit ​​mechanism, the disassembly of the bobbin is efficient and convenient. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 3This utility model provides a technical solution: a yarn spool for a jacquard knitting machine, comprising multiple spool assemblies 2 installed inside the jacquard knitting machine 1. Each spool assembly 2 consists of a limiting seat 21, a vertical rod 22, and a shaft 23. The spool assembly 2 is used to fix the position of the yarn spool 3. The limiting seat 21 is located at the top of the vertical rod 22, and the shaft 23 is located on the side of the vertical rod 22. The top of the shaft 23 is engaged with the inside of the limiting seat 21, and the bottom of the shaft 23 is installed inside the jacquard knitting machine 1. The surface of the shaft 23 is fitted with the yarn spool 3, which is used to store yarn. The yarn spool 3 consists of a spool body 31 and symmetrically arranged end caps 32. The symmetrically arranged end caps 32 are located at both ends of the spool body 31, and a locking mechanism is provided at the connection points between the symmetrically arranged end caps 32 and both ends of the spool body 31. The yarn spool 3 is designed to be detachable, improving the situation where, during the operation of the jacquard knitting machine, the yarn spool 3 used for storing and supplying yarn is partially damaged. The spool 3 is a one-piece structure, which makes it inconvenient to disassemble and replace. By making the spool 3 detachable, partial replacement can be performed when the spool 3 is partially damaged. Furthermore, since the spool body 31 and the end cap 32 are assembled by a snap-fit ​​mechanism, the disassembly of the spool 3 is efficient and convenient. The end cross-sectional dimensions of the spool body 31 and the end cross-sectional dimensions of the end cap 32 are the same. The spool body 31 is a hollow cylindrical structure, and the snap-fit ​​mechanism consists of a slot 31. 1. Composed of a locking block 312 and a locking assembly 313, the locking mechanism enables the installation between the cylinder 31 and the end cap 32. The cylinder 31 is located at the bottom of the end cap 32. The locking block 312 is located inside the locking groove 311. The bottom end of the locking block 312 is fixed to the end of the cylinder 31. The locking assembly 313 is located between the outer side of the locking block 312 and the inner side of the locking groove 311. The locking block 312 is a hollow cylindrical structure, and the top edge of the locking block 312 is arc-shaped.

[0020] In this embodiment, preferably, the engaging assembly 313 consists of a limiting groove 3131, a spring block 3132, and a movable cavity 3133. The movable cavity 3133 is located on the outside of the locking block 312. The engaging assembly 313 is used to engage and fix the locking groove 311 and the locking block 312. The limiting groove 3131 is located on the outside of the end cap 32 and is in communication with the locking groove 311. The spring block 3132 is located inside the movable cavity 3133 and inside the limiting groove 3131. The bottom end of the spring block 3132 is fixed to the bottom end of the movable cavity 3133. The side cross-section of the spring block 3132 is L-shaped. When the engaging assembly 313 is in use, the elastic force of the spring block 3132 at the connection between the spring block 3132 and the movable cavity 3133 causes the end of the spring block 3132 to engage or disengage from the limiting groove 3131.

[0021] The working principle and usage process of this utility model are as follows: In this jacquard knitting machine, the bobbin assembly 2 is used to fix the bobbin 3, and the bobbin 3 provides the yarn required for the knitting process, ensuring a continuous supply of yarn during production. When the bobbin 3 is partially damaged, the bobbin body 31 and end cap 32 that make up the bobbin 3 are disassembled. First, place your finger on the limiting groove 3131 and press the end of the spring block 3132. Through the elasticity between the bottom end of the spring block 3132 and the movable cavity 3133, the end of the spring block 3132 is separated from the limiting groove 3131 and stored inside the movable cavity 3133, so that the locking groove 311 and the locking block 312 lose their limiting. Then, pull the end cap 32 and the bobbin body 31 in opposite directions to separate the locking block 312 from the locking groove 311, thus completing the disassembly of the end cap 32 and the bobbin body 31.
