Technical Field

The invention belongs to the technical field of shuttleless loom accessories, and particularly relates to a warp stopping frame with a water retaining function.

Background

The foregoing shuttleless looms include rapier looms, air jet looms, projectile looms, water jet looms, and the like. The warp stop frame has the function of arranging warp stop strips, the warp stop strips are penetrated by warp stop sheets, a plurality of warp stop sheets are penetrated on each warp stop strip, each warp stop sheet is penetrated by a warp, the warp stop sheets are suspended on the warp stop strips by the warp, and specifically, the chips on the warp stop strips and the iron package are in a non-conduction state (the chips and the iron package are insulated and separated by an insulating film such as a polyimide film). In the weaving process of the weaving machine, when the warp yarn passing through a certain dropper breaks, namely the warp breaking which is commonly known in the industry, the warp yarn loses the suspended tube bundle of the dropper, so that the dropper which is originally in the suspended state falls onto the dropper, and the dropper conducts the chip which is originally in the insulation separation state with the package iron. At the moment, the signal is fed back to an electric control device of the shuttleless loom by the warp stopping strip junction box on the warp stopping frame, so that the shuttleless loom is stopped, the broken warp yarns are connected by workers, and the shuttleless loom resumes working. Therefore, the machine halt immediately after the warp breaking is an important measure for ensuring that the fabric is prevented from generating flaws.

Technical information related to the above-mentioned dropper and dropper thereof, such as CN2315126Y (dropper), CN2425097Y (dropper), CN202954203U (dropper), CN2550388Y (warp broken display device of dropper), CN2635693Y (light-emitting dropper), CN201024274Y (automatic stop device for electronic warp broken of silk loom), CN201169671Y (loom with warp leasing device), CN103061010B (dropper), CN201817661U (protection device for broken warp of loom), CN2082274U (electronic warp stop device of loom), CN201080536Y (electronic display device for broken warp of dropper), CN201080537Y (structurally improved dropper), and CN104372505Y (bracket structure in dropper), etc., is not known in the published chinese patent documents.

As mentioned above, water jet looms belong to the category of shuttleless looms, which operate on the principle of using a jet of water to pull the weft yarn through the shed. The friction traction force of the water-jet weft insertion to the weft yarn is larger than that of the air-jet weft insertion, the diffusivity is small, the requirements of long-wire weft insertion of synthetic fibers, glass fibers and the like with relatively smooth surfaces are met, meanwhile, the conductivity of the synthetic fibers can be increased, and static electricity in weaving is effectively overcome.

As described above, since the water jet loom mainly weaves fabrics with a relatively low grade, no drop wire stand has been provided on the water jet loom so far, and the broken filament cannot be detected by the car stop in time, but only after the defective cloth of several meters or more is seen. Furthermore, if the warp stopping frame is matched with the water jet loom, it is considered that the warp stopping frame does not have the function of water blocking or water blocking, so that the warp stopping frame and the warp stopping strips thereof are leaked when water splashes, and on one hand, the circuit is frequently conducted to cause abnormal halt, and on the other hand, the safety is concerned.

However, in recent years, with the increasing demands on the grade of fabrics, for example, the filaments as raw materials are relatively thin, the filaments are easy to break, and if the filaments cannot be found and disposed in time, the quality of the fabrics cannot be guaranteed. If a structure similar to the warp stop motion for a water jet loom recommended by chinese patent publication No. CN202347215U is used, the technical effects described in paragraph 0005 of the specification can be reflected to some extent, but when water splashes from the water jet loom and electric components such as the induction wire and the parallel switch described in the patent are splashed, the above abnormal stop motion is often generated, which affects the working efficiency of the water jet loom and increases the extra working strength of a car stop. In view of the foregoing, if the water splash and the drop wire of the water jet loom can be eliminated, the measure of matching the drop wire with the water jet loom is undoubtedly a positive and beneficial measure. The technical solutions described below have been created in this context.

In the present embodiment, the water curtain 24 is a non-metal film and has a corrugated cross-sectional shape, more vividly, a corrugated tile shape as seen in daily life. The upper part of the water-retaining curtain 24 is penetrated by the water-retaining curtain suspension rope 2413, and the lower part, namely the lower edge is supported on the group of warp stop strip middle supporting plates 16, more specifically, the lower part, namely the lower edge of the water-retaining curtain 24 is contacted with the warp stop strip middle supporting plates 16 but is not fixed, so that the water-retaining curtain 24 can show the curtain-like opening or closing effect when warp is broken and stops and warp receiving treatment is needed. When the water retaining curtain is opened, the two sides of the water retaining curtain 24 are folded towards the direction of the water retaining curtain middle upright post 23, and vice versa. After the water curtain 24 is opened, broken warps can be conveniently processed (the broken warps are connected) by a vehicle stop, and after the broken warps are processed, namely the broken warps are connected, the water curtain 24 is closed, so that the water curtain 24 is unfolded towards the direction far away from the water curtain middle upright post 23.

In this embodiment, the non-metal film is a plastic film, and the plastic film is a polyvinyl chloride (PVC) film, but a polyethylene film, a polypropylene film, or a polystyrene film may be used.

The invention is installed on the water-jet loom in the category of shuttleless loom, the water splashed by the water-retaining curtain 24 in the working process of the water-jet loom can be blocked by the water-retaining curtain 24 and can not splash to the drop wire junction box 11 and the group of drop wires 12, thereby ensuring the normal play of the normal warp stop response action of the drop wire frame assembly 1.

In conclusion, the dropper assembly 1 is creatively applied to the water jet loom on the premise of matching with the water retaining curtain mechanism 2, so that the defects in the prior art are overcome, the invention task is successfully completed, and the technical effects recorded in the technical effect column by the applicant are faithfully realized.
