Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a warp let-off device for textile equipment. Background Art

[0002] Textile equipment is a general term for various mechanical equipment that processes natural fibers or chemical fibers into the required textiles. In order to achieve the required quality of the finished product during the textile process, the warp and weft threads in the textile process must have a specific density and a certain tension.

[0003] Most existing textile equipment controls the tension of the warp by rotating the resistance of the wire feed roller or by additionally setting a tensioner. It is not possible to complete the tension control of the warp during the warp feeding process, and it is necessary to purchase other equipment or increase the conveying distance of the warp, which increases the processing cost and the failure rate during the processing. Utility Model Content

[0020] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the following further elaborates the present utility model in conjunction with specific embodiments and the accompanying drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0021] The following describes the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] As Figure 1-3 shown, a warp feeding device for a textile device includes a connecting frame 1. Inside the connecting frame 1, a side support rod 2 and a central rod 3 are installed. The connecting frame 1 is two U-shaped frames arranged facing each other. On its side facing each other, there are a side support rod 2 and a central rod 3. Among them, the side support rod 2 is arranged on both sides of the U-shaped frame, and the central rod 3 is arranged at the central position of the U-shaped frame. A fixed sliding sleeve 4 is sleeved outside the side support rod 2, and a movable sliding sleeve 5 is sleeved outside the central rod 3. Both the side support rod 2 and the central rod 3 are cross-shaped concave pipes. And two fixed sliding sleeves 4 are sleeved on the surface of each side support rod 2, and one movable sliding sleeve 5 is sleeved outside each central rod 3. The fixed sliding sleeve 4 is a pipe sleeve with a threaded hole on its surface and a bolt is threadedly connected in the threaded hole. The bolt is located inside the threaded hole and its end abuts against the side support rod 2. The inner wall of the movable sliding sleeve 5 is smooth and lubricated. A connecting rotating shaft 6 is arranged on the surfaces of the fixed sliding sleeve 4 and the movable sliding sleeve 5. A connecting rotating shaft 6 is arranged on the surface of the fixed sliding sleeve 4 on the side of the side support rod 2 close to the bottom and close to the central rod 3. A wire feeding roller 9 is arranged on the opposite side of the fixed sliding sleeve 4 close to the top. Connecting rotating shafts 6 are arranged on both sides of the movable sliding sleeve 5. The output end of the connecting rotating shaft 6 is provided with a connecting seat 7. The end of the connecting seat 7 is provided with a gas spring 8. The fixed end of the gas spring 8 is located on the side close to the fixed sliding sleeve 4, and the movable end is on the side close to the movable sliding sleeve 5. The gas spring 8 is always in a contracted state. A wire feeding roller 9 is arranged inside the fixed sliding sleeve 4 and the movable sliding sleeve 5.

[0024] The working principle is as follows: first, the fixed sleeve 4 without the connecting shaft 6 on the surface is fixed within the required height of the side support rod 2, and then the fixed sleeve 4 with the connecting shaft 6 is set on the surface of the side support rod 2 close to the fixed sleeve 4 without the connecting shaft 6. At this time, the gas spring 8 contracts and pulls the movable sleeve 5 to be flush with the fixed sleeve 4 with the connecting shaft 6 through the connecting seat 7 and the connecting shaft 6, and then the warp is passed through the wire feeding roller 9 in sequence. Then the operator loosens the fixed sleeve 4 with the connecting shaft 6 and moves it downward. During the movement, the movable sleeve 5 at the end of the gas spring 8 moves with it, driving the wire feeding roller 9 to move. The wire roller 9 moves downward to pull the warp thread, causing tension in the warp thread. When the expanded length of the gas spring 8 increases, the pulling force increases, and the downward pressing force of the wire feed roller 9 increases, thereby increasing the tension of the warp thread. After the operator observes and determines that the tension has reached the required value, the position of the fixed sleeve 4 with a connecting shaft is fixed to maintain the current expanded length of the gas spring 8, ensuring that the gas spring 8 always pulls the movable sleeve 5 through the connecting seat 7 and the connecting shaft 6 to keep its position relatively fixed without causing a large change in the warp thread tension. When a failure occurs in the textile equipment and the tension suddenly increases, the warp thread will pull the wire feed roller 9 located on the inner side of the movable sleeve 5 to move upward to avoid warp thread breakage.
