Two rotating rods 10 are rotatably installed at the two ends of the top of the threading frame 3, and an inclined plate 12 is obliquely arranged on the inner side of the threading frame 3; a limit block 14 is arranged on the threading frame 3, and when the connecting slider 13 contacts the limit block 14, there is a gap between the bottom end of the inclined plate 12 and the bottom end of the threading frame 3, so that the wire can be smoothly inserted into the inner bottom end of the threading frame 3; the upper ends of the two adjacent rotating rods 10 on the two adjacent lead mechanisms are rotatably connected by a rotating connector 11; the two adjacent groups of sliding assemblies are connected by a connecting soft rope 18; the two groups of sliding assemblies at the two ends are fixedly connected to the two ends of the telescopic assembly, so that the two lead mechanisms at the two sides are immovable, and only the multiple lead mechanisms in the middle move, ensuring that the multiple connecting soft ropes 18 can form a taut state.

[0032] Specifically, the complete structure and working method of a shuttle-woven fabric weaving machine are as follows, and the technical method improves the threading part on the heald frame of the shuttle-woven fabric weaving machine.

[0033] The existing woven fabric weaving machine structure includes:

[0034] The warp let-off mechanism includes a warp beam and a tension adjustment device. The warp beam is an important part of the warp let-off mechanism and is used to wind the warp yarn. The warp beam is usually made of metal or other high-strength materials with a smooth surface to reduce the friction of the warp yarn. The tension adjustment device adjusts the tension of the warp yarn through various mechanical or electronic means to ensure that the warp yarn maintains uniform tension during the weaving process, making the quality of the fabric more stable. Common tension adjustment methods include using tension disks, springs, etc.

[0035] The opening mechanism includes a heald frame, on which are mounted healds, through which the warp yarns pass; when the heald frame moves up and down, the warp yarns are driven to separate up and down to form a shed; the opening mechanism also includes a cam, a connecting rod or a multi-arm mechanism: the function of these mechanisms is to control the movement law of the heald frame, so that the heald frame moves up and down in a certain order and time interval, thereby forming different shed shapes to meet the requirements of different fabric structures.

[0036] Weft insertion mechanism, the weft insertion mechanism includes a shuttle. Traditional shuttle looms use shuttles as weft insertion tools. There is a weft tube inside the shuttle. Driven by the loom, the shuttle quickly passes through the shed to introduce the weft yarn into the shed. Yarn weft insertion can also use new weft insertion devices such as rapier, air jet, and water jet: In order to improve the speed and efficiency of weft insertion, modern shuttle looms use new weft insertion methods such as rapier, air jet, and water jet. Rapier weft insertion is to clamp the weft yarn through the rapier head and introduce it into the shed; air jet weft insertion is to use the jet force of compressed air to blow the weft yarn through the shed; water jet weft insertion is to use the high-pressure water flow to pull the weft yarn through the shed.

[0037] The beating-up mechanism includes a sley: a steel reed is mounted on the sley, and the function of the steel reed is to push the weft yarn introduced into the shed toward the weft mouth, so that it is tightly interwoven with the warp yarn; the beating-up mechanism also includes a pull handle and a rocker shaft, which transmit power to the sley, so that the sley moves back and forth to complete the beating-up action.

[0038] The take-up mechanism includes a cloth winding roller, which is used to wind up the woven fabric so that the fabric is continuously wound down from the cloth fell; the take-up mechanism also includes a transmission device, which transmits power to the cloth winding roller through transmission parts such as gears and chains, controls the rotation speed and winding amount of the cloth winding roller, and ensures that the winding speed of the fabric matches the weaving speed.

[0039] The control mechanism includes an electrical control system, which uses advanced electronic technology and computer control technology to accurately control the various mechanisms of the loom. It can realize the functions of automatic start, stop, speed regulation, fault diagnosis, etc. of the loom, and improve the automation degree and production efficiency of the loom.

[0040] The control mechanism also includes sensors: sensors are installed in various parts of the loom to detect parameters such as warp tension, weft yarn breakage, loom speed, etc., and feed back the detection signals to the control system so as to adjust the operating status of the loom in time.

[0041] The following is the working principle of the shuttle woven fabric weaving machine:

[0042] Shedding: The shedding mechanism controls the up and down movement of the heald frame according to the requirements of the fabric structure, so that the warp yarn is divided into two layers, forming a shed. Different fabric structures require different shedding methods. For example, plain weave requires a simple up and down alternating shedding, while twill weave requires a more complex shedding sequence.

[0043] Weft insertion: The weft insertion mechanism introduces the weft yarn into the shed. In traditional shuttle looms, the shuttle flies in the shed and brings the weft yarn to the other side of the loom; modern looms use rapiers, air jets or water jets to quickly and accurately introduce the weft yarn into the shed.

[0044] Beating up: The sley of the beating up mechanism makes reciprocating motion back and forth. When the weft yarn is introduced into the shed, the sley swings forward, driving the reed to push the weft yarn to the weaving mouth, so that the weft yarn and the warp yarn are closely interwoven to form the weft density of the fabric.

[0045] Winding: The winding mechanism winds the woven fabric from the cloth fell onto the cloth winding roller, while maintaining the appropriate tension of the fabric so that the weaving process can proceed continuously. The amount of winding is adjusted according to the type and specification of the fabric.

[0046] Warp let-off: The warp let-off mechanism delivers the warp yarn in a timely manner according to the weaving speed of the fabric and the consumption of the warp yarn to ensure the stability of the warp yarn tension. The control of the warp let-off amount needs to be precise to ensure the uniformity of the warp density of the fabric.

[0047] During the entire weaving process, the control mechanism monitors the operating status and various parameters of the loom in real time through sensors, and accurately controls each mechanism according to a preset program to ensure efficient and stable operation of the loom and produce high-quality fabrics; the above content is the public technical scope of the shuttle-woven fabric weaving machine, so it will not be repeated here.

[0048] In the technical solution, the structure of the yarn threading is improved to improve the threading efficiency of the yarn.

[0049] Before threading, the length of the telescopic assembly is adjusted by using the adjustment assembly. The threaded rod 8 can be driven to move by adjusting the rotation direction of the threaded rod 8. The movement of the threaded rod 8 can drive the first slide plate 1 to move. When the first slide plate 1 moves away from the second slide plate 2, the length of the telescopic assembly becomes longer, and vice versa. The telescopic assembly is adjusted to the maximum length. At this time, the multiple connecting soft ropes 18 are in a taut state, so that the distance between the two adjacent lead mechanisms reaches the maximum value, which is convenient for subsequent threading work; then the wire is inserted between the two rotating rods 10 at the upper end of the lead mechanism. At this time, the two rotating rods 10 form a "V" shape, so that the wire can easily slide through the two rotating rods 10 to the inner side of the threading frame 3. After the wire enters the inner side of the threading frame 3 through the opening 301, the wire is continuously pulled downward, and the wire passes through the inclined The bottom end of the plate 12 slides into the inner bottom end of the threading frame 3. It should be added that the inclined plate 12 is made of a material with strong toughness and has a certain elasticity. In the initial state, the bottom end of the inclined plate 12 is in contact with the inner wall of the threading frame 3. When the thread moves to the bottom end position of the inclined plate 12, the bottom end of the inclined plate 12 is deformed. At this time, a gap is formed between the bottom end of the inclined plate 12 and the inner wall of the threading frame 3 for the thread to pass through. When the thread is separated from the inclined plate 12, the inclined plate 12 is quickly reset to achieve the limit of the thread and prevent the thread from passing through the opening 301; the subsequent threads are threaded according to the above method; after the threading work is completed, the telescopic assembly is adjusted to the shortest length by the adjustment assembly again, and multiple lead mechanisms are reset at this time; during the weaving process, the telescopic assembly is driven up and down by the linear drive mechanism to achieve the opening of the warp yarn.

[0050] Embodiment 2

[0051] like Figure 1 and Figure 3 As shown, a shuttle-woven fabric weaving machine proposed in this embodiment, compared with the first embodiment, in this embodiment, one end of the telescopic assembly is connected to a second support rod 5, and a distance sensor 6 is installed on the upper end of the second support rod 5; a connecting slider 13 is connected to the inclined plate 12, and the connecting slider 13 is vertically slidably installed on the threading frame 3, and the front end of the inclined plate 12 extends to the front side of the threading frame 3; when the yarn is driven to move downward, the inclined plate 12 moves upward relative to the threading frame 3 under the limiting action of the yarn. If the inner yarn of a threading frame 3 breaks at this time, the inclined plate 12 on the inner side of the threading frame 3 is stationary relative to the threading frame 3, and the corresponding inclined plate 12 is blocked at the detection end position of the distance sensor 6 at this time, so that the detection data of the distance sensor 6 changes, and the distance sensor 6 immediately feeds back the signal to the PLC controller, and then the PLC controller controls the alarm to work, which can play the function of automatic wire break alarm; in summary, the setting of the above structure can detect wire breakage, and its structure is simple and the detection cost is low.

[0052] The present invention also provides a weaving method of the above-mentioned woven fabric weaving machine, comprising the following steps:

[0053] S1: Use the adjustment component to adjust the telescopic component to the maximum length. At this time, multiple connecting soft ropes 18 are in a taut state, so that the distance between two adjacent lead mechanisms is equal, that is, the distance between two adjacent lead mechanisms is expanded to facilitate subsequent threading work.

[0054] S2: Pass the wire through the two rotating rods 10 at the upper end of the wire guide mechanism. At this time, the two rotating rods 10 form a "V" shape, so that the wire can easily slide through the two rotating rods 10 to the inner side of the threading frame 3. After the wire passes through the opening 301 and enters the inner side of the threading frame 3, continue to pull the wire downward, and the wire slides through the bottom end of the inclined plate 12 to the inner bottom end of the threading frame 3; thread the subsequent wires according to the above method.

[0055] S3: The telescopic assembly is adjusted to the shortest length by adjusting the assembly again, and at this time, the multiple lead mechanisms are reset.

[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
