This utility model discloses a high-speed jacquard wide-width spacing adjustment device for an air-jet loom, relating to the technical field of the textile industry. The utility model includes: a base, a double-headed screw horizontally arranged at the center of the base, a partition plate on the top of the base, left and right adjustment seats sleeved on both sides of the partition plate, a height screw on the top of the left and right adjustment seats, a height adjustment seat sleeved on the surface of the height screw, and a mounting plate on one side of the height adjustment seat. A fixed guide wheel is installed inside the mounting plate. This utility model separates the double-headed screw from the fabric through the partition plate, effectively preventing thread ends and other debris from falling onto the double-headed screw, reducing the frequency of subsequent cleaning. Simultaneously, the height of the height adjustment seat and the mounting plate are adjusted by the screw sleeve and rotating gear sleeve on the height screw, allowing the device to adjust its height to fit the fabric, thus increasing the device's flexibility.

The present application relates to the technical field of chemical fiber, and particularly relates to a preparation process of four-color jacquard fabric based on printing effect and the fabric. According to the printing four-color principle, the preparation process selects red, blue, yellow and black four colors and color yarns with fineness of 30D / 24F-50D / 36F as warp yarns; selects white or black color yarns with fineness of 50D / 36F-75D / 72F as weft yarns; twists the selected warp yarns respectively, configures yarns with required colors according to the printing four-color mode by using the four-color warp yarns; selects red, blue, yellow and black four-color yarns as warp yarns and white or black color yarns as weft yarns, weaves by using heavy warp organization and a jacquard loom to obtain a jacquard fabric; and obtains the corresponding fabric by finishing the jacquard fabric. The process changes the current situation that the traditional multi-color jacquard fabric is thick, heavy and expensive, realizes the product innovation of the jacquard fabric which is colorful and light and thin; compared with the printed fabric, not only the limitation of material use is overcome, but also the color fastness and environmental protection performance of the product are improved.

The application relates to the technical field of textiles, and discloses a zero-start jacquard process, which comprises the following steps: S1, receiving an electronic pattern manuscript: before production, a designer usually uses a design method pattern or a pattern, and receives an electronic pattern manuscript from a client; S2, scanning into a jacquard loom computer end: scanning the electronic manuscript into the jacquard loom computer end to perform image processing and adjustment; S3, automatically arranging and threading heddles and reeds: the computer end automatically performs arrangement and action calculation of threading heddles and reeds through processing of the pattern image, and transmits the calculation result to the loom to perform operation; S4, directly weaving out a sample according to the calculation result: the loom weaves out a sample according to the position of each yarn and the requirement of the pattern; and S5, delivering the sample to the client for auditing and confirmation. The application can meet the requirement of small-mi sample drawing of jacquard products, and can accept the adjustment requirement of the designer for the pattern.

This utility model relates to the field of jacquard loom technology, and in particular to an eccentric wheel double-opening mechanism and jacquard loom, including a frame, a swing shaft wall plate on a connecting frame, a first heddle swing shaft and a first jacquard heddle swing shaft respectively arranged between the swing shaft wall plates at both ends and a first bottom beam, and a second heddle swing shaft and a second jacquard heddle swing shaft respectively arranged between the swing shaft wall plates at both ends and a second bottom beam. This utility model also discloses a jacquard loom. The eccentric wheel double-opening mechanism and jacquard loom obtained by this utility model, by adjusting the position of the swing shaft wall plate to match the appropriate length of the first heddle swing shaft, the first jacquard heddle swing shaft, the second heddle swing shaft, and the second jacquard heddle swing shaft, can adjust the number and arrangement of the lifting blades of the heddles and the jacquard heddles. Simultaneously, the opening of the jacquard heddles and the opening of the heddles can be adjusted according to actual needs, improving the ease of adjustment of the loom and making it suitable for a wider range of heddle fabric weaving needs.

This utility model discloses a power transmission device for a direct-drive cam-driven jacquard loom machine with a main spindle motor. The device includes a main spindle motor, a common input / output shaft, conjugate cams, driven swing arms, and swing shafts. The frame has a crossbeam and cam box-type wall plates fixed to both sides of the crossbeam. The cam box-type wall plates house the common input / output shaft and conjugate cams respectively mounted on the corresponding common input / output shaft. Each of the two cam box-type wall plates has a drive side wall plate, a cam box body, and a box cover. The inner ends of the two common input / output shafts are supported on the corresponding drive side wall plates, while the outer ends are supported on the corresponding box covers. One of the two driven swing arms is fixed to one end of a swing shaft, and the other is fixed to the opposite end of the other swing shaft. The double rollers of the two driven swing arms cooperate with the corresponding conjugate cams. The two box covers respectively fix the main spindle motor. The shaft ends of the two common input / output shafts extending from the corresponding box covers are respectively fixed in the shaft holes of the corresponding main spindle motors. Using this design results in good dynamic balance, uniform vibration distribution, and reduced swing shaft cantilever.

The application relates to the technical field of textile machinery, in particular to a multi-pattern natural fiber jacquard loom transmission mechanism. The transmission mechanism comprises a rack main body, a driving device, a transmission assembly, a jacquard execution assembly and a damping protection assembly; the driving device comprises a driving motor and a motor mounting seat, and the output shaft end of the driving motor is provided with a first transmission gear; the transmission assembly comprises a transmission shaft, a second transmission gear meshed with the first transmission gear and a third transmission gear connected with a pattern control mechanism; the jacquard execution assembly comprises a jacquard box body, a plurality of jacquard needle bars arranged in a matrix mode and the pattern control mechanism, and the pattern control mechanism comprises a cam set connected with the third transmission gear and a transmission connecting rod connecting the cam set and the jacquard needle bar. The application can significantly improve the transmission precision and efficiency, reduce the vibration and noise during high-speed operation, reduce the friction and damage of natural fibers during the jacquard process, reduce the rate of broken warp and realize the synchronous and accurate control of multi-patterns.
