Description
Technical Field

[0002] The variable width loom can flexibly adjust the width of the fabric during the weaving process through its unique adjustment structure. This adjustment is usually based on the synergy of software control and hardware structure to achieve precise width adjustment. The characteristics of variable width looms include high flexibility, stability and high efficiency, which can meet the production needs of fabrics with different width requirements. The warp feeding mechanism is an important mechanism of the variable width loom. During the weaving process, a certain amount of warp yarn with a certain tension is fed out to maintain continuous weaving. Limit plates are often installed on both sides of the bracket by bolts during the warp transmission process. The limit plates on both sides are used to limit the transmission range of the warp yarn. When the width and direction of the warp yarn need to be changed, the limit plates can be installed in a specific suitable position by removing the bolts for quick adjustment. The adjustment structure of this type of variable width loom has the following problems: the guide unit of the warp yarn, such as the limit plate, is threadedly connected to the specified position of the bracket by bolts, and evenly distributed screw holes are opened. Although adjustments can be made, they are limited by the position of the screw holes of the bolt connection, and each replacement and adjustment requires personnel to repeatedly disassemble, replace, adjust the inclination and install, which is complex and troublesome, and will result in low weaving efficiency of the loom.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the adjustment structure of the variable width loom has the following advantages:
[0014] 1. According to the required width of weaving, the personnel rotate the bidirectional screw through the driving handle. The rotation of the bidirectional screw makes the adjusting seat move toward the center of the conveyor frame under the guidance of the guide rod. The adjusting seats move toward each other and drive the two longitudinally adjacent connecting seats to move toward the center of the conveyor frame. The two transversely adjacent connecting seats move toward each other and drive the longitudinally adjacent adjusting handles to move toward the center of the conveyor frame. The two transversely adjacent adjusting handles move toward each other and drive the longitudinally adjacent guide seats to move toward the center of the conveyor frame. The position of the limit unit can be adjusted by rotating the screw assembly alone at a specific position. It is no longer limited by the position of the screw hole of the bolt connection. The personnel will not have the trouble of repeated disassembly and installation, and can quickly adjust the required width of weaving.
[0015] 2. The left and right ends of the warp yarn slide through the corresponding guide grooves. The guide grooves provide guidance for the transmission of the warp yarn, so that the warp yarn is transmitted at the required width. When the warp yarn passes through the guide grooves, as the rising and falling angles of the warp yarn change, the guide seats follow the changes in the warp yarn transmission angle and rotate under the action of the connecting shaft, thereby realizing the adaptive satisfaction of the warp yarn transmission angle. At the same time, the warp yarn generates a downward force on the guide seat, and the guide seat transmits the force to the upper end of the laterally adjacent adjustment handle through the corresponding connecting shaft, thereby making the adjustment handle rotate around the corresponding pin shaft center axis, and at the same time making the torsion spring twist the special force, and the force applied to the guide seat by the torsion spring and the warp yarn is always balanced, thereby effectively satisfying The transmission inclination angle and tension requirement of the warp yarn. When the warp yarn passes through the upper end of the adjusting roller, the warp yarn generates a downward pulling force on the adjusting roller, causing the adjusting roller to move downward, and then the sliding blocks all move downward inside the corresponding slide grooves. The downward movement of the sliding blocks causes the telescopic ends of the vertically adjacent telescopic columns to extend, and at the same time, the vertically adjacent springs are elastically stretched. The elastic force of the springs and the pulling force of the warp yarn on the adjusting roller are always balanced. When the warp yarn is being transported, the guide unit can follow the changes in the warp yarn transmission inclination angle and tension requirement. At this time, there is no need to disassemble the guide unit again when the inclination needs to be adjusted, thereby avoiding the trouble caused by repeated disassembly and improving the weaving efficiency of the loom to a certain extent.

[0021] See also Figure 1-3 , This embodiment provides a technical solution: an adjustment structure of a variable width loom, including a transmission frame 1 and a width adjustment component 2;
[0022] Conveying rack 1: Conveying rollers 3 are rotatably connected at both the front and rear ends of the conveying rack 1, and a symmetrically distributed connecting plate 10 is fixedly connected at the lower end of the conveying rack 1, and evenly distributed mounting holes are arranged inside the connecting plate 10;
[0023] Width adjustment assembly 2: It includes guide rods 23, adjustment seats 24, connecting seats 25, adjustment handles 27, connecting shafts 28 and guide seats 29. The guide rods 23 are fixedly connected to the inside of the conveying frame 1. The front and rear ends between the two guide rods 23 are slidably connected with the adjustment seats 24. The left and right ends of the adjustment seats 24 are fixedly connected with the connecting seats 25. The inside of the connecting seats 25 is rotatably connected with pins. The middle of the pins is fixedly connected with adjustment handles 27. The upper ends of the adjustment handles 27 are rotatably connected with connecting shafts 28. The ends of the connecting shafts 28 close to the center of the conveying frame 1 are fixedly connected with guide seats 29. The ends of the guide seats 29 close to the center of the conveying frame 1 are provided with guide grooves. The width adjustment assembly 2 also includes a driving handle 21 and a bidirectional screw 22. The bidirectional screw 22 is rotatably connected to the inside of the conveying frame 1. The inside of the adjustment seat 24 is threadedly connected to the corresponding ends of the bidirectional screw 22. The bidirectional screw 22 The right end is fixedly connected with a driving handle 21, and the width adjustment component 2 also includes a torsion spring 26, which is symmetrically fixedly connected between the adjusting handle 27 and the laterally adjacent connecting seats 25, and the torsion springs 26 are movably sleeved on the outer surfaces of the vertically adjacent pin shafts. According to the required width of the weaving cloth, the bidirectional screw 22 is rotated by the driving handle 21, and the rotation of the bidirectional screw 22 causes the adjusting seats 24 to move toward the center of the conveying frame 1 under the guidance of the guide rod 23. The adjustment seats 24 move toward each other and drive the two longitudinally adjacent connecting seats 25 to move toward the center of the conveying frame 1. The two laterally adjacent connecting seats 25 move toward each other and drive the longitudinally adjacent adjusting handles 27 to move toward the center of the conveying frame 1. The two laterally adjacent adjusting handles 27 move toward each other and drive the longitudinally adjacent guide seats 29 to move toward the center of the conveying frame 1, thereby realizing the spacing adjustment of the limit units.
[0024] Wherein: slide grooves 4 are arranged at both ends of the conveying frame 1, and sliding blocks 7 are slidably connected inside the slide grooves 4, and an adjusting roller 8 is rotatably connected between the two sliding blocks 7, and the upper ends of the slide grooves 4 are fixedly connected with telescopic columns 5, and the telescopic ends of the telescopic columns 5 are fixedly connected with the upper ends of the vertically adjacent sliding blocks 7. Springs 6 are fixedly connected between the sliding blocks 7 and the top walls of the corresponding slide grooves 4, and the springs 6 are movably sleeved on the outer surfaces of the laterally adjacent telescopic columns 5. The operation of the motor 9 is realized by controlling the switch 11, and the rotation of the output shaft of the motor 9 drives the laterally adjacent conveying rollers 3 to rotate. The warp yarn passes through the lower end of the conveying roller 3 on the front side, the upper end of the adjusting roller 8 and the lower end of the conveying roller 3 on the rear side in sequence, and then enters the weaving area. The left and right ends of the warp yarn slide through the corresponding guide grooves, which provide a guiding effect for the transmission of the warp yarn, so that the warp yarn is transmitted at the required width. When the warp yarn passes through the guide groove, as the rising and falling angles of the warp yarn change, the guide seats 29 follow the warp yarn transmission. The change of the feeding angle is rotated under the action of the connecting shaft 28, thereby realizing the adaptive satisfaction of the warp yarn transmission angle. At the same time, the warp yarn generates a downward force on the guide seat 29, and the guide seat 29 transmits the force to the upper end of the laterally adjacent adjusting handle 27 through the corresponding connecting shaft 28, so that the adjusting handle 27 rotates around the corresponding pin shaft center axis, and at the same time, the torsion spring 26 is twisted with a special force, and the torsion spring 26 and the force applied to the guide seat 29 by the warp yarn are always balanced, thereby effectively meeting the transmission inclination angle and tension requirements of the warp yarn. When the warp yarn passes through the upper end of the adjusting roller 8, the warp yarn generates a downward pulling force on the adjusting roller 8, so that the adjusting roller 8 moves downward, and then the sliding block 7 moves downward inside the corresponding slide groove 4. The downward movement of the sliding block 7 makes the telescopic end of the vertically adjacent telescopic column 5 stretch, and at the same time, the vertically adjacent spring 6 is elastically stretched, and the elastic force of the spring 6 and the pulling force of the warp yarn on the adjusting roller 8 are always balanced, thereby effectively and adaptively meeting the different tension requirements of the warp yarn;
[0025] Among them: a control switch 11 is arranged at the front end of the right side surface of the conveying frame 1, and the input end of the control switch 11 is electrically connected to an external power supply; a motor 9 is arranged at the rear end of the right side surface of the conveying frame 1, and the left end of the output shaft of the motor 9 is fixedly connected to the right end of the conveying roller 3 on the rear side, and the input end of the motor 9 is electrically connected to the output end of the control switch 11.
[0026] The working principle of the adjustment structure of the variable width loom provided by the utility model is as follows: when working, the personnel stably connect the mounting hole inside the connecting plate 10 with the threaded hole in the working area through bolts, and the personnel rotate the bidirectional screw 22 through the driving handle 21 according to the required width of the weaving cloth. The rotation of the bidirectional screw 22 makes the adjustment seat 24 move toward the center of the conveying frame 1 under the guidance of the guide rod 23. The adjustment seat 24 moves toward each other, and drives the two longitudinally adjacent connecting seats 25 to move toward the center of the conveying frame 1. The two transversely adjacent connecting seats 25 move toward each other. The movement of the two adjusting handles 27 adjacent in the longitudinal direction drives them to move toward the center of the conveying frame 1, and the two adjusting handles 27 adjacent in the transverse direction move toward each other and drive the guide seats 29 adjacent in the longitudinal direction to move toward the center of the conveying frame 1. When the guide seats 29 reach the required position, the personnel stops rotating the driving handle 21, and then the personnel controls the switch 11 to operate the motor 9. The rotation of the output shaft of the motor 9 drives the conveying rollers 3 adjacent in the transverse direction to rotate. The warp yarn passes through the lower end of the conveying roller 3 on the front side, the upper end of the adjusting roller 8 and the lower end of the conveying roller 3 on the rear side in turn, and then enters the weaving area. The ends of the warp yarns all slide through the corresponding guide grooves, which provide guidance for the transmission of the warp yarns, so that the warp yarns are transmitted at the required width. When the warp yarns pass through the guide grooves, as the rising and falling angles of the warp yarns change, the guide seats 29 all follow the changes in the warp yarn transmission angles and rotate under the action of the connecting shaft 28, thereby realizing the adaptive satisfaction of the warp yarn transmission angle. At the same time, the warp yarns generate a downward force on the guide seat 29, and the guide seat 29 transmits the force to the upper end of the laterally adjacent adjusting handle 27 through the corresponding connecting shaft 28, so that the adjusting handle 27 all rotates around the corresponding pin shaft center axis, and at the same time, the torsion spring 26 The torsion holding force, the force applied by the torsion spring 26 and the warp yarn to the guide seat 29 is always balanced, thereby effectively meeting the transmission inclination angle and tension requirements of the warp yarn. When the warp yarn passes through the upper end of the adjusting roller 8, the warp yarn generates a downward pulling force on the adjusting roller 8, causing the adjusting roller 8 to move downward, thereby causing the sliding blocks 7 to move downward inside the corresponding slide groove 4. The downward movement of the sliding blocks 7 causes the telescopic ends of the vertically adjacent telescopic columns 5 to stretch, and at the same time causes the vertically adjacent springs 6 to elastically stretch. The elastic force of the spring 6 and the pulling force of the warp yarn on the adjusting roller 8 are always balanced, thereby effectively and adaptively meeting the different tension requirements of the warp yarn.
[0027] It is worth noting that the control switch 11 disclosed in the above embodiment is provided with a control button corresponding to the motor 9 and controlling the switch thereof.
[0028] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
