Description

Technical Field

[0001] The utility model relates to the technical field of fabric width adjustment, in particular to a jacquard width adjustment mechanism for silk fabrics. Background Art

[0002] Large jacquard looms are used to weave large jacquard fabrics. They are large patterned fabrics woven with jacquard machines. The number of warp yarns in a complete patterned fabric ranges from a few hundred to several thousand. Large jacquard fabrics are mostly based on one fabric, and another or several different fabrics are used to display patterns on it, such as plain weave and satin weave. The width is the actual width of the fabric, the distance between the outermost warp yarns on both sides of the fabric, also known as the width. By adjusting the width of the fabric, the width of the jacquard can be adjusted.

[0003] The patent specification with announcement number CN216919789U discloses a jacquard width adjustment mechanism for silk fabrics, which includes a box body; a movable disk is vertically slidably connected to the box body and is relatively arranged, and a movable block is laterally slidably connected to the movable disk, and a transmission part with one end connected to the movable block is rotatably connected to the movable disk. The transmission part can drive the movable block to move laterally. It can clean the fabric in advance during the process of stretching the fabric, which changes the existing technology of directly adjusting the width of the fabric, improves the cleanliness of the fabric, and further saves labor.

[0004] However, in the implementation of relevant technologies, it was found that the jacquard width adjustment mechanism for silk fabrics designed above has the following problems: in the above technical solution, a transmission member is used to drive the moving block to move laterally, and the moving block drives the adhesive roller to clean the dust and particles on the surface of the fabric during the lateral movement, thereby changing the existing technology of directly adjusting the width of the fabric and improving the cleanliness of the fabric. However, due to the characteristics of the fabric itself, the fluff adhered to the surface of the fabric cannot be well cleaned using a vacuum cleaner, resulting in fluff impurities still adhering to the surface of the fabric. In view of this, a jacquard width adjustment mechanism for silk fabrics is provided to overcome the above defects. Utility Model Content

[0023] As a further implementation scheme of the above technical scheme: a vacuum cleaner 10 is fixed to the outer surface of the mounting frame 1 by bolts, and the input end of the vacuum cleaner 10 is connected to a conveying pipe 11. When the vacuum cleaner 10 is started, suction is generated at the vacuum end to suck in impurities on the surface of the fabric.

[0024] As a further implementation scheme of the above technical scheme: the end of the conveying pipe 11 is connected to a dust collecting piece 12 fixedly connected to the mounting frame 1, an exhaust hole 13 is opened inside the dust collecting piece 12, and a cleaning brush 14 is fixed to the inner wall of the dust collecting piece 12. When the cloth is conveyed, the cleaning brush 14 contacts the outer surface of the cloth, thereby cleaning the impurities on the surface of the cloth that are difficult to adsorb, causing the impurities to fall off and being convenient to be sucked out.

[0025] In specific implementation, before using the jacquard width adjustment mechanism for silk fabrics, first place the mounting frame 1 in a suitable position, pass the fabric through the through hole 2 on the mounting frame 1 through the feed port, pass between two dust collectors 12, pass between two lint-sticking rollers 6, and pull out through another through hole 2, then fix this end to the external winding device, and the external device winds up the fabric. At this time, the vacuum cleaner 10 is started, and suction is generated inside the dust collector 12 through the conveying pipe 11 and the exhaust hole 13 to suck in impurities on the surface of the fabric. When the fabric is conveyed, the cleaning brush provided 14 contacts with the outer surface of the cloth, thereby cleaning the impurities on the surface of the cloth that are difficult to absorb, making the impurities fall off and facilitating suction. When the cloth passes between the two lint-sticking rollers 6, the spring 8 in the mounting tube 3, under the action of the spring 8's own elasticity, pushes the limit block 9 to move, so that the movable rod 4 drives the fixed frame 5 to move, and the two lint-sticking rollers 6 approach each other and contact with the outer surface of the cloth, thereby adhering the lint that is difficult to clean on the surface of the cloth, and the fixed bearing 7 is provided to enable the two lint-sticking rollers 6 to rotate, thereby ensuring the normal transportation of the cloth, thereby improving the cleaning effect of the device.

The set guide rod 19 can play a guiding role to prevent the movable block 18 from deviating.

[0029] As a further implementation scheme of the above technical scheme: an adjusting electric cylinder 20 is fixed to the lower surface of the movable block 18, and a pulling plate 21 is fixed to the telescopic end of the adjusting electric cylinder 20. The adjusting electric cylinder 20 drives the pulling plate 21 to move vertically, so that the lower surface of the pulling plate 21 contacts the upper surface of the cloth, which is convenient for pulling.

[0030] During specific implementation, when the cleaned cloth is on the adjustment plate 15, the cloth is stopped from being conveyed, and the adjusting electric cylinder 20 drives the pulling plate 21 to move vertically, so that the lower surface of the pulling plate 21 contacts the upper surface of the cloth. At this time, the dual-axis motor 16 is started to drive the screw rod 17 to rotate. With the cooperation of the guide rod 19, the rotation of the screw rod 17 drives the movable block 18 to move horizontally, thereby driving the two pulling plates 21 to move relative to each other, stretching the cloth and realizing the function of width adjustment.
