Description

Technical Field

[0001] This utility model relates to the field of mercerized knitted underwear technology, specifically a yarn guide device for a jacquard knitting machine used in the production of mercerized knitted underwear. Background Technology

[0002] Knitted underwear is a category of knitted garments that come into direct contact with the skin in the textile and apparel market. It has functions such as warmth, sweat absorption, skin protection, preventing stains on outer clothing, and body shaping. Underwear needs to be made and processed using jacquard knitting machines. The yarn guide device of the jacquard knitting machine is mainly used to guide and control the movement trajectory of the knitting yarn, ensuring uniform yarn tension and preventing yarn slippage or friction.

[0003] For example, Chinese patent CN212955594U discloses a guiding mechanism for a jacquard knitting machine, which includes a machine body and a first slide groove. A first slider is embedded inside the first slide groove. A guide rod is fixedly connected to the other side of the first slider. A second slide groove is provided on the other side of the guide rod. A first guide block is embedded inside the second slide groove. An iron block is welded to the top of the first guide block. Limit plates are provided on both sides of the iron block. A first nut is welded to one side of the limit plate. This invention utilizes a guide ring to guide and limit the knitting yarn, preventing it from detaching during operation. The circular guide ring reduces friction with the yarn. If the yarn is too tight or too loose during operation, the position of the second guide block can be adjusted to alleviate this problem. Furthermore, if the tension is too high or too low, the position of the first sliding block can be adjusted to regulate the yarn tension. Traditional yarn feeding guide devices cannot effectively control the tension during yarn feeding. When the tension is too high or the feeding speed is too fast, the yarn wears significantly, easily leading to yarn breakage. Therefore, this invention proposes a yarn feeding guide device for jacquard knitting machines producing mercerized knitted underwear to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a yarn feeding guide device for jacquard knitting machines producing mercerized knitted underwear, which has advantages such as adjustable yarn tension and solves the problem of inconvenient control of yarn feeding tension in traditional methods.

There are two sets of mounting rods, which are arranged vertically. One end of each mounting rod is provided with a mounting component, and the mounting rod is fixedly installed on the outer surface of the main frame through the mounting component. A guide shaft is set on the outer surface of the main frame and is located between two sets of mounting rods. One end of the guide shaft is provided with an adjustment component, which is used to adjust the lateral movement of the guide shaft to control the tension of the yarn.

[0006] Preferably, the mounting assembly includes a mounting block fixedly mounted on the outer surface of the main frame. One end of the mounting rod is provided with a connecting groove, and the mounting block is threadedly connected to the connecting groove. The pressure plate structure is mounted through the mounting rod. When disassembly and replacement are required, the mounting rod can be rotated to detach the bottom end of the mounting rod from the mounting block, making disassembly and replacement convenient.

[0012] 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.

[0013] Please see Figure 1-3 The present invention provides the following technical solution: a jacquard knitting machine infeeding guide device for producing mercerized knitted underwear, including a main frame 1, with mounting plates 11 integrally connected to the rear of both ends of the main frame 1, and guide frames 12 fixedly installed at the upper and lower ends of the main frame 1, with a wire tube 13 embedded inside the outer surface of the guide frame 12. In this embodiment, the mounting rod 2 is installed on the front outer surface of the main frame 1, and there are two sets of mounting rods 2. The two sets of mounting rods 2 are arranged vertically. One end of the mounting rod 2 is provided with a mounting component, and the mounting rod 2 is fixedly installed on the outer surface of the main frame 1 by the mounting component. The installation assembly includes an installation block 21 fixedly installed on the outer surface of the main frame 1. One end of the installation rod 2 is provided with a connecting groove, and the installation block 21 is threadedly connected to the connecting groove. The pressure plate structure is installed through the installation rod 2. When it is necessary to disassemble and replace, the installation rod 2 can be rotated so that the bottom end of the installation rod 2 is detached from the installation block 21, which facilitates disassembly and replacement. In this embodiment, it should also be noted that a guide rod 23 is fixedly installed at one end of the mounting rod 2, and a base plate 22 and a pressure plate 26 are sleeved on the outer surface of the guide rod 23. A stop block 24 is fixedly installed at one end of the guide rod 23, and a first spring 25 is sleeved on one side of the outer surface of the guide rod 23 located on the stop block 24. One end of the first spring 25 is in contact with one side of the outer surface of the pressure plate 26. When passing around the guide rod 23, the base plate 22 and the pressure plate 26 limit the movement. At the same time, the pressure plate 26 is pressed by the first spring 25 to prevent it from moving back and forth during the conveying process. In this embodiment, the guide shaft 3 is disposed on the outer surface of the main frame 1 and is located between the two sets of mounting rods 2. One end of the guide shaft 3 is provided with an adjustment component, and the lateral movement of the guide shaft 3 is adjusted by the adjustment component to control the tension of the yarn.

[0014] The adjustment assembly includes a groove 14 on the outer surface of the main frame 1, a slide rod 33 fixedly installed inside the groove 14, a slider 32 sleeved on the outer surface of the slide rod 33, and a second spring 34 sleeved on one side of the outer surface of the slide rod 33 near the slider 32. A connecting rod 31 is fixedly installed at one end of the guide shaft 3, and one end of the connecting rod 31 is fixedly connected to the outer surface of the slider 32. When the tension is too high, the guide shaft 3 will be pressed and pushed to one side, thereby causing the slider 32 to slide along the slide rod 33, compressing the second spring 34, further shortening the thread conveying path, and thus reducing the tension of the thread conveying.

[0015] The working principle of this embodiment is as follows: In use, the main frame 1 is installed and fixed by the mounting plate 11. The wire first enters the guide tube 13 inside the upper guide frame 12, passes around the upper guide rod 23, the guide shaft 3 and the lower guide rod 23 in sequence, and then passes out from the lower guide frame 12. When passing around the guide rod 23, it is limited by the chassis 22 and the pressure plate 26. At the same time, the pressure plate 26 is pressed by the first spring 25 to prevent it from moving back and forth during the conveying process. The position of the guide shaft 3 can be adjusted laterally. When the tension is too high, the guide shaft 3 will be pressed and pushed to one side, thereby driving the slider 32 to slide along the slide bar 33, squeezing the second spring 34, further shortening the thread conveying path, thereby reducing the tension of the thread conveying and thus reducing the wear on the thread conveying. The pressure plate structure is installed via the mounting rod 2. When it needs to be disassembled and replaced, the mounting rod 2 can be rotated so that the bottom end of the mounting rod 2 can be detached from the mounting block 21 for easy disassembly and replacement.
