Description

Technical Field

[0001] This utility model relates to the field of air-jet loom equipment technology, and in particular to an automatic yarn changing device for air-jet looms. Background Technology

[0002] In the rapid development of the modern textile industry, efficient and intelligent weaving equipment has become the key to improving productivity and product quality. As a representative technology in this field, the air-jet loom, through innovative compressed air jet technology, introduces the weft yarn into the warp yarn opening at high speed and with precision, completely revolutionizing the traditional weaving mode.

[0003] Air-jet looms are a type of modern high-speed loom that uses compressed air to guide the weft yarn into the warp opening, thus completing the weaving of the fabric. With its high speed and automation advantages, air-jet looms have become the mainstream equipment in the modern textile industry.

[0004] In the production process of air-jet looms, yarn changing is a crucial step that directly affects the loom's production efficiency and product quality. However, traditional yarn changing devices typically change individual yarn bobbins sequentially, a process that takes a lot of time and requires pausing the loom each time a new yarn bobbin is replaced, which severely impacts the overall working efficiency of the air-jet loom. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic yarn changing device for air-jet looms, which aims to improve the problems of traditional yarn changing requiring manual operation, slow operation efficiency, long downtime, and fixed yarn supply angle.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic yarn changing device for an air-jet loom, comprising a first connecting column, wherein a feeding component is fixedly connected to one end of the first connecting column;

[0007] The feeding assembly includes a yarn loading box, a spring fixedly connected to the inner wall of the yarn loading box, a first slide rail fixedly connected to the inner wall of the yarn loading box, a second slide rail fixedly connected to the inner wall of the yarn loading box, a first support column and a second support column opened inside the yarn loading box, a yarn loading opening opened on the outer wall of the yarn loading box, a spring seat fixedly connected to one end of the spring, a yarn package frame fixedly connected to the outer wall of the spring seat, a first bearing fixedly connected to the outer wall of the yarn package frame, a second bearing fixedly connected to the outer wall of the first support column, and a third bearing fixedly connected to the outer wall of the second support column.

[0008] Furthermore, a universal ball is fixedly connected to one end of the first connecting column, a locking bolt is rotatably connected to the outer wall of the universal ball, and a locking nut is threadedly connected to the inner wall of the locking bolt.

[0009] Furthermore, a first slider is slidably connected to the inner wall of the first slide rail, and a second connecting post is fixedly connected to the outer wall of the first slider, with one end of the second connecting post fixedly connected to the outer wall of the spring seat.

[0010] Furthermore, a second slider is slidably connected to the inner wall of the second slide rail, and a third connecting post is fixedly connected to the outer wall of the second slider, with one end of the third connecting post fixedly connected to the outer wall of the spring seat.

[0011] Furthermore, a first support frame is fixedly connected to one end of the locking bolt, and a yarn frame seat is fixedly connected to one end of the first support frame.

[0012] Furthermore, the outer ring of the first bearing is slidably connected to a bobbin, the outer wall of the bobbin is rotatably connected to the outer ring of the second bearing, and the outer wall of the bobbin is rotatably connected to the outer ring of the third bearing.

[0013] Furthermore, a second support frame is fixedly connected to one end of the yarn box, and a wire hole is provided at one end of the second support frame.

[0014] Furthermore, the outer wall of the universal ball is rotatably connected to the outer wall of the locking nut, and the universal ball is rotatably connected to the inner wall of the locking bolt.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a clip-type feeding assembly is constructed using springs and bearings. The spring serves as the core transmission body, and the bearings are used as the yarn feeding and ejection unit. When the remaining yarn amount is high, the top bearing jams the yarn, preventing it from passing through the gap between the two bearings. At this time, the bottom spring is compressed to store potential energy. When the remaining yarn amount is sufficient to pass through the gap between the two top bearings, the bottom spring releases its elastic potential energy, causing the top yarn to eject, thus achieving automatic yarn changing.

[0017] 2. In this utility model, a rotating assembly is constructed by locking nuts, locking bolts and universal balls. The universal ball is used as the core rotating body, and the locking nuts and locking bolts are used as fixing units. When the yarn feeding angle of the yarn package is not suitable, simply rotate the yarn box to the appropriate angle, and then rotate the locking bolts at the bottom to achieve multi-directional changes in the yarn feeding angle.

[0025] 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.

[0026] Reference Figures 1-5 An embodiment of this utility model is provided: an automatic yarn changing device for an air-jet loom, including a first connecting column 6, one end of which is fixedly connected to a feeding component;

[0027] The feeding assembly includes a yarn loading box 22, with a spring 7 fixedly connected to the inner wall of the yarn loading box 22, a first slide rail 12 fixedly connected to the inner wall of the yarn loading box 22, a second slide rail 11 fixedly connected to the inner wall of the yarn loading box 22, a first support column 17 and a second support column 25 opened inside the yarn loading box 22, and a yarn loading opening 21 opened on the outer wall of the yarn loading box 22. By opening the yarn loading opening 21 on the outer wall of the yarn loading box 22, the yarn package 13 can be quickly loaded. A spring seat 8 is fixedly connected to one end of the spring 7, and a yarn package frame 14 is fixedly connected to the outer wall of the spring seat 8. The yarn loading assembly is adjusted downwards... Pressing the yarn package frame 14 causes the spring seat 8 to compress the spring 7 downwards, thereby storing elastic potential energy in the spring 7. The outer wall of the yarn package frame 14 is fixedly connected to the first bearing 15, the outer wall of the first support column 17 is fixedly connected to the second bearing 20, and the outer wall of the second support column 25 is fixedly connected to the third bearing 16. By setting a certain gap between the second bearing 20 and the third bearing 16, the yarn package 13 installed on the first bearing 15 can only pass through the gap between the second bearing 20 and the third bearing 16 when the remaining yarn is insufficient, thus realizing the replacement of the yarn package 13.

[0028] Reference Figure 4 It includes a first connecting post 6, one end of which is fixedly connected to a universal ball 5. A locking bolt 4 is rotatably connected to the outer wall of the universal ball 5, and a locking nut 3 is threadedly connected to the inner wall of the locking bolt 4. By rotating the first connecting post 6, the universal ball 5 inside the locking bolt 4 is rotated, and then the locking nut 3 at the bottom of the locking bolt 4 is rotated to fix the universal ball 5, thereby achieving the effect of multi-angle yarn supply.

[0029] Working principle: During operation, the yarn package 13 is first passed through the yarn loading port 21, and then the yarn package 13 is fixed on the first bearing 15 on the yarn package frame 14. Since the diameter of the yarn package 13 is too large, it cannot pass through the gap between the second bearing 20 and the third bearing 16. Therefore, the yarn package frame 14 slides downward on the first slide rail 12 and the second slide rail 11, thereby compressing the spring 7 connected below the spring seat 8. When the yarn package 13 at the top is almost used up, the diameter of the yarn package 13 becomes smaller until it can pass through the gap between the second bearing 20 and the third bearing 16. The spring 7 at the bottom, which is compressed, releases its elastic potential energy, causing the spring seat 8 to drive the yarn package frame 14 to move upward on the first slide rail 12 and the second slide rail 11, thereby popping out the nearly used yarn package 13 and realizing the replacement of the yarn package 13.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
