Description

A yarn feeding system for a double-needle bed flat yarn warp knitting machine

technical field

The invention relates to a yarn supply system using flat yarn as a raw material, in particular to a yarn supply system for a double-needle bed flat yarn warp knitting machine, which belongs to the technical field of warp knitting equipment.

Background technique

Warp knitting technology, with its unique loop forming form and the knitting characteristics of various large-scale mesh structures, makes warp knitting machines with low gauge and large gauge suitable for the production of industrial raw materials such as sunshade nets, woven bags, and fishing nets. The field can be rapidly expanded and applied. Especially with the emergence of multifunctional film materials composited with polyolefin resin and various anti-aging materials, after heating, stretching, cutting or spinning, and then warping by a special flat warping machine, it is provided to the warp knitting machine. Machine for weaving, can produce a variety of single-layer and double-layer agricultural and construction and other industrial materials.

The high speed and high efficiency of warp knitting machine weaving largely depends on the good warping process before weaving. The production of flat yarn warp knitting products is organized by segmented yarn supply, and the assembly line is designed in the order of yarn separation, warping, and weaving. Since flat yarn raw materials are usually difficult to order directly from the market in the form of ordinary raw materials, weaving manufacturers can only purchase special Advanced plastic extruders, film splitting devices, flat wire heating devices, stretching machines and stress relief devices, flat wire warping machines and other series of processing equipment, resulting in too long production lines, many types of equipment, large floor space, and high input costs. Moreover, the raw material ratio and production process of polyolefin film materials are relatively complicated, and most weaving manufacturers are not familiar with it and it is difficult to master it.

As shown in Figure 1, the front needle bed warp yarn flat yarn feeding system 101 is located on the outer side of the front side of the main knitting part 1 of the double needle bed warp knitting machine, following the direction of yarn advancement, the yarn path of the front needle bed warp yarn flat yarn 5 In turn, it includes the front needle bed warp yarn breakage detection device 10101, the front needle bed warp yarn feeding warp shaft unit 10102, the front needle bed warp guide roller 10103, the front needle bed warp tension indicator 10104, the front needle bed warp yarn dividing button 10105, Front needle bed warp guide comb 10106. Among them, the front needle bed warp flat yarn broken yarn detection device 10101 provides yarn breakage detection for each front needle bed warp flat yarn 5. Due to the transparency of the flat yarn, the front needle bed warp flat yarn broken yarn detection device 10101 adopts doffing The reed relies on the gravity drop method to detect the yarn breakage of each flat yarn;

The detailed detection principle is as follows:

As shown in Fig. 3 and Fig. 4, the inner conductive sheet 4002, the insulating layer 4003, the outer conductive sheet 4004 and the warp knitting yarn flat yarn on all segmented detection frames 401 are all obtained from the strips of the 4001 in the doffing reed. When the flat yarn tension can meet the normal operation of the warp knitting machine, the doffing reed 4001 is pulled up and suspended by the flat yarn, and the inner conductive sheet 4002 and the outer conductive sheet 4004 are disconnected due to the isolation of the insulating layer 4003. The cathode of the diode 5001 on the segmented broken yarn detection circuit 501 is at a high level, no current flows through the diode 5001 and its anode is at a high level, the LED alarm indicator light 5002 is off, and the alarm output signal 503 has no output; When the flat yarn is broken or the tension is not enough to support the normal operation of the warp knitting machine, the doffing reed 4001 falls on the inner conductive sheet 4002 due to gravity, because the doffing reed 4001 itself is a steel conductor, so that the inner conductive sheet 4002 and the outer conductive sheet 4004 Connected and short-circuited, so that the cathode of the diode 5001 connected to the outer conductive sheet 5004 and the cathode of the LED alarm indicator 5002 are both low level, so the LED alarm indicator 5002 is lit, and current flows through the diode 5001 at the same time. The anode of the diode 5001 jumps from high level to low level, and the alarm output signal 503 outputs a low level alarm signal. Although at this moment in the broken yarn detection system on the entire complete yarn road, only the anode of the diode 5001 on the segmented yarn broken detection circuit 501 is extremely low level, and the other segmented broken yarns connected together are also connected to each other simultaneously. The anode of the diode 5001 on the detection circuit 501 is also pulled down to a low level, but because no alarm is detected on the other segmented yarn breaking detection circuits 501, the negative poles of the diodes 5001 on the other segmented yarn breaking detection circuits 501 Extremely high level, using the unidirectional conductivity of the diode, it can be seen that at this time, no current will flow through the diode 5001 on the other segmented yarn breaking detection circuit 501, so the LEDs on the other segmented yarn breaking detection circuit 501 The warning indicator light 5002 still keeps going out. As shown in Figure 5, the PLC controller 8 will set a flag to record the arrival of the alarm level after receiving the alarm signal falling edge (alarm level is low level) input by the alarm output signal 503 on a certain yarn road Timer, start timing T1 when the alarm signal level is kept low. The timing length T1 can be artificially set and changed according to the vibration situation of the machine on the production site. When the timing length T1 arrives, it can be confirmed that it is a real flat wire break. When a yarn fault occurs, the PLC controller 8 stops the machine operation and gives a broken yarn alarm message; if the level of the alarm output signal 503 input appears a high-level jump during the time period T1 does not arrive, the alarm level is immediately canceled. Arrival flag, stop and clear the timing at the same time, think that the occurrence of this alarm signal is the false trigger caused by the fluctuation of the tension of the flat yarn because of some reason such as machine vibration, PLC controller 8 does not output the broken yarn alarm information and continues Keep the machine running, and use the program software to simulate the filtering effect of the broken yarn alarm signal to avoid false detection of broken yarn.
