Description

Technical Field

[0001] The utility model relates to the technical field of textile production, in particular to a weft selection device for producing large jacquard fabrics. Background Art

[0002] Large jacquard fabric, also known as large pattern fabric, is a large patterned fabric woven by a jacquard machine. The number of warp yarns in the complete patterned fabric ranges from hundreds to thousands. Large jacquard fabric is mostly based on one kind of fabric, and another or several different kinds of fabrics are used to show patterns on it, such as plain weave and satin weave. Sometimes, warp and weft yarns of different colors can be used to make the fabric present colorful large patterns. Different fiber types, yarn counts and different warp and weft densities can also be used to make jacquard fabrics of various styles.

[0003] When jacquard fabrics are produced by machines, in order to improve textile efficiency, people use weft selectors to operate them. Existing weft selectors are usually fixed to the production machines with bolts, and the number of weft yarns required for different jacquard fabrics is different. Therefore, each time a jacquard fabric is woven, a weft selector of a different specification needs to be replaced. Therefore, fixing the weft selector with bolts will make it take a lot of time to disassemble and install the weft selector each time, thereby affecting the production speed of the jacquard fabric.

[0019] Reference Figure 1-3 A weft selection device for producing large jacquard fabrics comprises a mounting block 1, a support shaft 7 is fixedly arranged inside the mounting block 1, a first fixing block 8 and a second fixing block 9 are fixedly arranged on the surface of the support shaft 7, a connecting block 2 is overlapped on the front side of the mounting block 1, a limit shaft 10 is movably arranged inside the connecting block 2, a limit ring plate 11 is fixedly arranged on the surface of the limit shaft 10, an elastic member 12 is arranged on the surface of the limit shaft 10, the elastic member 12 is a spring, one end of the elastic member 12 is fixedly connected to the inside of the connecting block 2, and the other end of the elastic member 12 is fixedly connected to the limit ring plate 11, and the limit shaft 10 is provided with a spring. When the movable limit ring plate 11 moves in the direction away from the support shaft 7, the elastic member 12 will be compressed, and the limit block 13 can be pressed against by the rebound of the elastic member 12, so that the limit block 13 is clamped between the first fixed block 8 and the second fixed block 9. The limit block 13 is fixedly arranged at one end of the limit shaft 10 close to the support shaft 7. There are two limit blocks 13, and the two limit blocks 13 are symmetrically distributed inside the connecting block 2. The two limit blocks 13 can make the installation of the weft selector 3 more stable. The limit block 13 overlaps with the first fixed block 8 and the second fixed block 9, and the surface of the connecting block 2 is fixedly provided with a weft selector 3. The weft selector 3 is provided with a linear rod 6 fixed inside. The number of the linear rods 6 is multiple. The linear rods 6 are controlled by an electronic control system, such as a computer, so that the linear rods 6 select different weft yarns. The weft selection device for large jacquard fabric production presses the weft selector 3 to move the connecting block 2. The connecting block 2 moves and drives the limiting block 13 to move through the limiting shaft 10. When the limiting block 13 moves, it is pushed by the first fixed block 8 to move in a direction away from the support shaft 7. The movement of the limiting block 13 compresses the elastic member 12. When the limiting block 13 moves to the first fixed block 8 and the second fixed block 8, the elastic member 12 is compressed. When the weft selector 3 is between the first fixed block 8 and the second fixed block 9, the limiting ring plate 11 is pushed to move in the direction of the supporting shaft 7 by the rebound effect of the elastic member 12, and the limiting ring plate 11 moves through the limiting shaft 10 to drive the limiting block 13 to be clamped between the first fixed block 8 and the second fixed block 9, and the weft selector 3 is installed. When the weft selector 3 is removed, the limiting shaft 10 is pulled first, and the limiting shaft 10 moves to drive the limiting block 13 to move away from the first fixed block 8 and the second fixed block 9, and the connecting block 2 and the weft selector 3 can be removed. The device is convenient for installing and disassembling the weft selector 3, thereby improving the speed of replacing weft selectors 3 of different specifications and improving the production speed of large jacquard fabrics.

[0020] A threading hole 4 is provided on the surface of the weft selector 3, and there are multiple threading holes 4. A protective ring 5 is fixedly arranged inside the threading hole 4. The protective ring 5 is made of silicone. There are two protective rings 5, and the two protective rings 5 ​​are symmetrically distributed inside the threading hole 4. The weft yarn is passed through the threading hole 4 and is protected by the protective ring 5 during transportation.

[0021] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0022] When in use: the mounting block 1 is fixed on the surface of the jacquard textile machine, the yarn is passed through the threading hole 4, the yarn is selected through the weft selector 3 and the linear rod 6, and the movement of the yarn is protected by the protective ring 5. When a different weft selector 3 needs to be replaced, it is only necessary to pull the limit shaft 10. The movement of the limit shaft 10 drives the limit ring plate 11 and the limit block 13 to move together, so that the elastic member 12 is compressed and the limit block 13 is away from the first fixed block 8 and the second fixed block 9. The connecting block 2 can be removed, thereby disassembling the old weft selector 3. When installing, it is only necessary to press the new weft selector 3 so that the connecting block 2 moves toward the mounting block 1, and the connecting block 2 moves through the limit The positioning shaft 10 drives the limit block 13 to move. When the limit block 13 moves and touches the first fixed block 8, the limit block 13 is pushed by the first fixed block 8 to move in the direction away from the support shaft 7. The movement of the limit block 13 drives the limit shaft 10 and the limit ring plate 11 to move. The limit ring plate 11 moves and compresses the elastic member 12. When the limit block 13 moves between the first fixed block 8 and the second fixed block 9, the limit ring plate 11 is pushed to move in the direction of the support shaft 7 through the rebound effect of the elastic member 12. The limit ring plate 11 moves through the limit shaft 10 to drive the limit block 13 to be clamped between the first fixed block 8 and the second fixed block 9, thereby fixing the new weft selector 3 on the surface of the textile machine.

[0023] In summary, the weft selection device for producing large jacquard fabrics presses the weft selector 3 to move the connecting block 2, and the connecting block 2 moves through the limiting shaft 10 to drive the limiting block 13 to move. When the limiting block 13 moves, it is pushed by the first fixed block 8 to move in the direction away from the support shaft 7. The movement of the limiting block 13 compresses the elastic member 12. When the limiting block 13 moves between the first fixed block 8 and the second fixed block 9, the limiting ring plate 11 is pushed to move in the direction of the support shaft 7 through the rebound effect of the elastic member 12. The limiting ring plate 11 moves through the limiting shaft 10 to drive the limiting block 13 to be clamped between the first fixed block 8 and the second fixed block 9, and the weft selector 3 is installed. When removing the weft selector 3, the limiting shaft 10 is pulled first, and the limiting shaft 10 moves to drive the limiting block 13 to move away from the first fixed block 8 and the second fixed block 9, and the connecting block 2 and the weft selector 3 can be removed. The device is convenient for installing and disassembling the weft selector 3, thereby improving the speed of replacing weft selectors 3 of different specifications and improving the production speed of large jacquard fabrics.
