Detailed ways

The utility model adopts an electronically controlled jacquard opening mechanism, an electromagnetically controlled magnetic shuttle weft insertion mechanism, an electronically controlled warp let-off and crimping mechanism, and an electronic CAD silk pattern control system to form a highly automated Kesi in a special way. Product weaving machinery and equipment.

As shown in Figures 1 and 2, the present embodiment includes an integral frame, an electronic take-up mechanism 1 installed at the front position of the machine, and an electronic warp let-off mechanism 2 installed at the rear position of the machine; An electronic jacquard shedding mechanism 4 is installed above the take-up mechanism and the electronic let-off mechanism, and an electronically controlled weft beating mechanism 6 and a variable range electromagnetic control type shuttle weft insertion mechanism 5 are located below the electronic jacquard shedding mechanism 4. An electronic control system 3 is installed on the outside of the machine.

The electronic winding mechanism: adopts a numerically controlled stepping motor, and automatically adjusts and controls each winding amount through a tension sensor adaptive to the tension change of the yarn.

The electronic warp let-off mechanism: a digitally controlled stepping motor is used to automatically adjust and control the length of the warp yarn sent out each time through the tension sensor adaptive to the tension change of the yarn.

The opening mechanism of the electronic jacquard machine: adopt the existing Stäubli electronic jacquard machine.

The electronically controlled beating-up mechanism: an intermittent electronically controlled beating-up mechanism is used, and a numerically controlled stepping motor is used to control the beating stroke.

As shown in Fig. 3, Fig. 4 and Fig. 5, the described variable-range electromagnetic control shuttle weft insertion mechanism: it is the core mechanism of the device, and the specific structure is: a shuttle guide plate 5-8 is installed on the sley 5-8. 2. A horizontally moving electromagnetic shuttle guide device with controllable movement is installed under the shuttle guide plate 5-2, and the shuttle 5-1 runs above the shuttle guide plate 5-2, which is a non-contact active weft insertion mechanism; There is a shuttle box device 5-4 that can move arbitrarily horizontally and can swing up and down or move with a controllable stroke. After the shed was opened, the reed 5-7 with the reed cap 5-6 was set on the sley 5-8, the sley 5-8 swung to the rear dead point, and the shuttle box 5-3 was controlled to move laterally to the desired position, Rod 5-5 swings or moves longitudinally onto the hook guide plate, and swings away after releasing the shuttle. The electromagnetic shuttle box device moves to this position synchronously under the shuttle guide plate through the driving screw 5-9, and the electromagnetic force is turned on to control the shuttle; Pneumatic device constrains the shuttle to rise or swing to a certain height, and then the beating mechanism does the beating motion; when using a flexible or rigid controllable stroke guide lever, the shuttle box swings to the picking position, and the guide shuttle The rod is stretched out, the rod head magnetically attracts the tail of the shuttle, and pushes it to the empty shuttle box on the opposite side, then the control magnetism disappears, the shuttle is released, and the guide rod retracts to the original position. The whole process is controlled by a computer program, with functions such as variable horizontal and vertical positions of the shuttle box (shuttle), variable weft insertion stroke, and random selection of shuttles.

The woven fabric is vertically interwoven by two sets of warp and weft yarns. This machine has five mechanisms of fully automatic control of shedding, weft insertion, beating-up, warp let-off and take-up.

According to the design requirements, the components of the five major mechanisms are installed on the frame of the automatic silk cutting machine: the frame is installed, the electronically controlled take-up mechanism is installed at the front position of the machine, and the electronically controlled warp let-off mechanism is installed at the rear position of the machine; An electronic jacquard shedding mechanism is installed above the warp let-off mechanism; an electronically controlled beating-up mechanism and a variable-range electromagnetic-controlled shuttle weft insertion mechanism are installed on the frame below the jacquard shedding mechanism; various sensors and auxiliary devices are installed outside the five major mechanisms. Each mechanism is connected to the electronic control system in front of the machine. In the control system, the corresponding pattern weaving file can be input through the U disk or the network interface, and the weaving process of each weft of the patterned Kesi fabric can be automatically controlled until it is completed. Its operation process is:

Kesi CAD software→pattern making of Kesi fabric→convert into weaving file→read electronic control system→control electronic warp let-off system to send warp yarn→control electronic jacquard machine to perform local shedding movement→control shuttle box to move laterally to throwing Shuttle position→control the shuttle box on the opposite side to traverse to the pick-up position and swing to the shuttle guide plate→release the shuttle from the shuttle box to the shuttle guide plate→control the shuttle box to disengage→the electromagnetic system controls the weft insertion movement of the shuttle to the shuttle box on the opposite side→ The shuttle box restrains the shuttle → controls the shuttle box to separate from the shuttle guide plate → closes the shed by the opening mechanism → controls the light beat-up → controls the other weft insertion sections of the same weft to repeat the five major movements → beats up → controls the take-up movement to roll the fabric away from the weaving mouth, Complete a weaving motion with a minimum cycle.

In summary, this utility model is based on the weaving characteristics of Kesi products through warp and weft breaking, and on the basis of the five major movements of woven fabric weaving: opening, weft insertion, weft beating, warp let-off, and coiling, and electronic control technology is used instead of manual operation. Cooperating with the specially developed Kesi electronic CAD system, the shuttle weft insertion mechanism with variable range electromagnetic control, and the shedding, beating-up, warp let-off, and coiling mechanisms, it constitutes the whole of the automated Kesi loom. The design and compilation of Kesi CAD software forms the coordinated control of the five major mechanisms, enabling the automatic Kesi machine to weave Kesi products automatically. The utility model can realize pattern weaving in 23 color segments, and the weaving rate is 20-24 wefts per minute.
