Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a yarn frame for a jacquard machine. Background Technology

[0002] A jacquard machine is a specialized piece of equipment used in the textile industry. It can create various complex patterns and designs on fabrics according to preset patterns and programs. Before using a jacquard machine, the yarn bobbins need to be placed on a yarn rack, which is one of the important components of the machine.

[0003] In the operation of a jacquard machine, the yarn rack serves to suspend yarn bobbins. A typical yarn bobbin consists of a bobbin body and yarn wound around it. The bobbin body is usually fitted onto the yarn rack's hanging rod, and one end of the yarn is pulled out and drawn by rollers, continuously feeding the yarn into the jacquard machine for knitting and weaving into fabric. A yarn rack usually holds several yarn bobbins; when all the yarn on one bobbin is used up, another unused bobbin must be immediately connected.

[0004] For ease of hanging, the diameter of the hanging rod is usually much smaller than that of the bobbin, making it easy to slip on. However, since the bobbin is not actually limited, the force generated by vibration and pulling during the process of the yarn being pulled can still cause the bobbin to be torn off, resulting in the bobbin falling off and affecting the operation of the jacquard machine. Utility Model Content

[0005] The purpose of this utility model is to provide a yarn frame for a jacquard machine in order to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a yarn rack for a jacquard machine, comprising a frame, wherein a plurality of hanging racks are provided on the frame, each hanging rack includes a yarn hanging rod, a stop bar is hinged to the yarn hanging rod, and a spring-loaded component is provided at the connection between the yarn hanging rod and the stop bar, the spring-loaded component being used to support the stop bar so that the stop bar is perpendicular to the yarn hanging rod in its natural state.

[0007] As a further feature of this invention, a connecting seat is provided on the yarn hanging rod, and a connecting piece is provided on the stop bar. The connecting piece is rotatably connected to the inside of the connecting seat via a rotating shaft.

[0008] As a further feature of this utility model, the yarn hanging rod is provided with a rotating seat, the connecting seat is disposed inside the rotating seat, and the spring-loaded assembly includes two torsion springs. One end of the torsion spring is connected to the rotating shaft, and the other end is connected to the side wall of the rotating seat. The two ends of the rotating shaft pass through the connecting seat and the torsion spring in sequence and are rotatably connected to the inner side wall of the rotating seat.

[0009] As a further feature of this invention, the tops of the connecting seat, connecting piece, and rotating seat are all semi-circular.

[0010] As a further feature of this invention, the connecting piece is detachably connected to the stop bar via a connector.

[0011] As a further feature of this utility model, the connector includes a disc fixedly connected to the connecting piece, the disc having a threaded head, and the stop bar having a threaded hole matching the threaded head.

[0012] As a further feature of this invention, the side wall of the stop bar is provided with several anti-slip grooves.

[0013] As a further feature of this utility model, the yarn hanging rod is provided with several mounting seats, several screws are connected to the mounting seats, and several nuts that match the screws are provided on the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the yarn bobbin needs to be replaced, this invention simply requires bending the stop bar downwards, changing its position from perpendicular to the yarn hanging rod to parallel to it. This releases the stop bar from obstructing the yarn bobbin, allowing it to be easily detached from the yarn hanging rod and then the stop bar, thus removing the old yarn bobbin. The new yarn bobbin is then inserted onto the yarn hanging rod through the stop bar. Releasing the stop bar again allows the spring-loaded component to restore its perpendicular position to the yarn hanging rod, effectively limiting the yarn bobbin and preventing it from being pulled off by external forces. This ensures the normal operation of the jacquard machine. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-3 As shown, a jacquard machine's yarn rack includes a frame 1 with several hangers on the frame 1. Each hanger includes a yarn hanging rod 2, and a stop bar 3 is hinged to the yarn hanging rod 2. A spring-loaded component is provided at the connection between the yarn hanging rod 2 and the stop bar 3. The spring-loaded component supports the stop bar 3 so that it is perpendicular to the yarn hanging rod 2 in its natural state. When it is necessary to change the yarn bobbin, simply bend the stop bar 3 downwards to change it from being perpendicular to the yarn hanging rod 2 to being parallel to it, thus releasing the stop bar 3 from obstructing the yarn bobbin. This allows the yarn bobbin to be easily moved from the yarn hanging rod 2 and the stop bar in sequence. The old yarn bobbin is disassembled by removing the stop bar 3. The new yarn bobbin is then inserted into the yarn hanging rod 2 through the stop bar 3. After releasing the stop bar 3, the spring-loaded component allows the stop bar 3 to return to a perpendicular position to the yarn hanging rod 2. The stop bar 3 can then block and limit the yarn bobbin, effectively restricting it to the yarn hanging rod 2 and preventing it from being torn off by external forces. This prevents the yarn bobbin from falling and ensures the normal operation of the jacquard machine. Several anti-slip grooves 12 are provided on the side wall of the stop bar 3, which greatly increases the friction coefficient on the side wall of the stop bar 3, making it less slippery when holding the stop bar 3 and easier to apply force.

[0023] Please see Figure 2-4As shown, a connecting seat 4 is provided on the yarn hanging rod 2, and a connecting piece 5 is provided on the stop rod 3. The connecting piece 5 is rotatably connected to the inside of the connecting seat 4 via a rotating shaft 6. Through the connection of the rotating shaft 6, the connecting piece 5 can rotate inside the connecting seat 4, thereby enabling the stop rod 3 to rotate smoothly on the yarn hanging rod 2, and thus the state of the stop rod 3 can be easily adjusted. A rotating seat 7 is provided on the yarn hanging rod 2, and the connecting seat 4 is located inside the rotating seat 7. The spring-loaded assembly includes two torsion springs 8, one end of which is connected to the rotating shaft 6, and the other end is connected to the side wall of the rotating seat 7. The two ends of the rotating shaft 6 pass through the connecting seat 4 and the torsion springs 8 in sequence and are rotatably connected. On the inner wall of the rotating seat 7, when the stop lever 3 is bent downwards, changing from a state perpendicular to the yarn hanging rod 2 to a state parallel to the yarn hanging rod 2, the rotating shaft 6 will rotate inside the rotating seat 7. This will cause the torsion spring 8 to twist and deform. When the stop lever 3 is released, the torsion spring 8 will automatically extend and return to its original shape, thus enabling the stop lever 3 to automatically return to a state perpendicular to the yarn hanging rod 2. The operation is relatively convenient and simple. The top of the connecting seat 4, the connecting piece 5, and the rotating seat 7 are all semi-circular, which makes the rotation of the connecting piece 5 inside the connecting seat 4 smooth and less prone to jamming.

[0024] Please see Figure 2-4 As shown, the connecting piece 5 is detachably connected to the stop rod 3 via a connector. When the stop rod 3 needs to be replaced, it can be separated from the connecting piece 5, allowing the stop rod 3 to be removed from the yarn hanging rod 2 for replacement, thus extending the service life of the hanger. The connector includes a disc 9 fixedly connected to the connecting piece 5, with a threaded head 10 on the disc 9. The stop rod 3 has a threaded hole 11 that matches the threaded head 10. By screwing the threaded head 10 into the threaded hole 11, the disc 9 can be connected to the stop rod 3, thus achieving a secure connection between the stop rod 3 and the yarn hanging rod 2. When the stop rod 3 needs to be disassembled, the threaded head 10 can simply be screwed out of the threaded hole 11, making the operation convenient and simple.

[0025] Please see Figure 1 , Figure 2 As shown, several mounting seats 13 are provided on the hanging rod 2, and several screws 14 are connected to the mounting seats 13. Several nuts matching the screws 14 are provided on the frame 1. The mounting seats 13 can be fixed to the frame 1 by the threaded connection between the screws 14 and the nuts, so that the hanger is firmly installed on the frame 1. The hanger can be removed by unscrewing the screws 14 from the nuts, which is convenient to operate.
