It includes a warp stop frame assembly, and its characteristics are: it also includes a water-blocking curtain mechanism, the lower part of which is fixed to one side of the length direction of the warp stop frame assembly, and the upper part of which extends upwardly away from the side of the length direction of the warp stop frame assembly. Since the water-blocking curtain mechanism is arranged on the side corresponding to the length direction of the warp stop frame assembly, the water-blocking curtain mechanism plays a water-blocking role, so that the warp stop frame assembly has a good water-blocking effect, avoiding water splashing of the water jet loom and the warp stop frame assembly causing an electrical short circuit of the warp stop frame assembly and further causing an abnormal shutdown of the water jet loom; since the water is blocked by the water-blocking curtain mechanism, the normal warp-breaking response effect of the warp stop frame assembly is guaranteed, the requirements for weaving high-grade fabrics by the water jet loom are met, and the added value of the products woven by the water jet loom is improved.

Description

Technical Field

[0001] The invention belongs to the technical field of shuttleless loom accessories, and in particular relates to a warp stop frame with a water-blocking function. Background Art

[0002] The aforementioned shuttleless looms include rapier looms, air jet looms, projectile looms and water jet looms, etc. The function of the aforementioned warp stop frame is to set the warp drop bar, and the function of the warp drop bar is to pass through the drop plate, and each warp drop bar is passed through a number of drop plates, and each drop plate is passed through a warp yarn, and the warp yarn makes the drop plate suspended on the drop bar, specifically, the chip on the drop bar is in a non-conductive state with the iron package (the chip and the iron package are insulated and separated by an insulating film such as a polyimide film). During the weaving process of the loom, when the warp yarn passing through a certain drop plate breaks, which is what the industry usually calls warp breakage, the warp yarn loses the suspension control of the drop plate, so that the drop plate originally in a suspended state falls onto the drop bar, and the aforementioned chip and the iron package, which were originally in an insulated and separated state, are connected by the drop plate. At this time, the warp bar junction box on the warp stop frame feeds back the signal to the electrical control device of the shuttleless loom, so that the shuttleless loom stops and the workers connect the broken warp yarns, and the shuttleless loom resumes work. It can be seen that stopping the loom immediately after the warp breaks is an important measure to ensure that the fabric does not have defective fabrics.

[0003] There is no lack of technical information related to the warp stop frame and its warp stop bars mentioned above in the public Chinese patent documents, such as CN2315126Y (warp stop frame), CN2425097Y (warp stop frame), CN202954203U (warp stop frame), CN2550388Y (warp break display device for warp stop bars), CN2635693Y (luminous warp drop sheet), CN201024274Y (electronic warp break automatic stop device for silk loom), CN2 01169671Y (loom with warp twisting device), CN103061010B (warp stop frame), CN201817661U (warp break protection device for loom), CN2082274U (electronic warp stop device for loom), CN201080536Y (warp break electronic display device for stop bar), CN201080537Y (stop bar with improved structure) and CN104372505Y (bracket structure in stop bar), etc.

[0004] As mentioned above, water jet loom belongs to the category of shuttleless looms. Its working principle is to use a jet of water to pull the weft yarn through the shed. The frictional traction of water jet weft insertion on the weft yarn is greater than that of air jet weft insertion, and the diffusion is small. It is suitable for the weft insertion of synthetic fibers, glass fibers and other filaments with relatively smooth surfaces. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving.

[0005] As mentioned above, since water jet looms are mainly used to weave relatively low-grade fabrics, they are not equipped with warp stoppers so far. When filament breakage occurs, the weaver cannot find it in time, and can only deal with it after seeing several meters or even longer defective fabrics. Moreover, if a warp stopper is equipped on a water jet loom, it is often considered unnecessary and troublesome by the industry, because the warp stopper does not have the function of blocking water, so when water splashes on the warp stopper and its warp stop bar, leakage occurs, which will cause abnormal shutdown due to frequent conduction of the circuit on the one hand, and safety concerns on the other hand.

[0006] However, in recent years, with the continuous improvement of people's requirements for fabric grades, for example, the filaments used as raw materials are relatively thin, and filament breakage is prone to occur. If it is not discovered and handled in time, the quality of the fabric cannot be guaranteed. If a structure similar to the "warp stop device for water jet looms" recommended by Chinese Patent Announcement No. CN202347215U is used, then to a certain extent, it can be reflected in the technical effects recorded in paragraph 0005 of its specification. However, when the water splashes of the water jet loom and the electrical components such as the induction wire and parallel switch described in the patent, the abnormal shutdown mentioned above will often occur, which will affect the working efficiency of the water jet loom on the one hand, and increase the extra work intensity of the loom stopper on the other hand. In view of the above, if the water splashes and the warp stop frame of the water jet loom can be eliminated, then the measure of matching the warp stop frame with the water jet loom is undoubtedly a positive and beneficial measure. The technical solution to be introduced below was produced in this context. Summary of the invention

[0029] Depend on Figure 2 As shown, the aforementioned first plug-in flange seat Ⅰ21111 and the aforementioned second plug-in flange seat Ⅱ22111 are in an L-shape; a group of intermediate support transition fixing plate screws 2311 are provided on the aforementioned water retaining curtain intermediate support transition fixing plate 231, and the intermediate support transition fixing plate screws 2311 are fixed to the right end of one of the aforementioned group of stop warp strip middle support plates 16 (the one located in the middle).

[0030] Water retaining curtain suspension rope holes 242 are provided at intervals on the upper part of the aforementioned water retaining curtain 24 and along the length direction of the water retaining curtain 24. The aforementioned water retaining curtain suspension positioning device 241 is connected with the aforementioned water retaining curtain first pillar tension spring fixing hole Ⅰ212, the water retaining curtain second pillar tension spring fixing hole Ⅱ222 and the water retaining curtain middle pillar rope groove 232 through the water retaining curtain suspension rope hole 242 together with the upper part of the water retaining curtain 24, and the lower part of the water retaining curtain 24 extends to the upper side of the right end of the support plate 16 in the aforementioned group of stop warp strips.

[0031] The applicant needs to explain that: in the present invention, although the water retaining curtain 24 exemplified is divided into two pieces with the middle support of the water retaining curtain as the boundary, this is only a difference in form and can be regarded as one whole piece in essence.

[0032] The aforementioned water retaining curtain suspension positioning device 241 includes a first tension spring I2411, a second tension spring II2412 and a water retaining curtain suspension rope 2413, one end of the first tension spring I2411 is fixed to the upper part of the aforementioned first water retaining curtain pillar I21 at a position corresponding to the aforementioned water retaining curtain first pillar tension spring fixing hole I212, the other end of the first tension spring I2411 is connected to one end of the water retaining curtain suspension rope 2413, and the other end of the water retaining curtain suspension rope 2413 is connected to one end of the second tension spring II2412 after passing through the aforementioned water retaining curtain suspension rope hole 242, and the other end of the second tension spring II2412 is fixed to the upper part of the aforementioned second water retaining curtain pillar II22 at a position corresponding to the aforementioned water retaining curtain second pillar tension spring fixing hole II222, and the middle part of the aforementioned water retaining curtain suspension rope 2413 is supported on the upper part of the aforementioned water retaining curtain middle pillar 23 at a position corresponding to the aforementioned water retaining curtain middle pillar rope groove 232.

[0033] exist Figure 2 and Figure 3 Also shown is a diagram for the aforementioned other end of the second tension spring 2412, namely Figure 2 The rear end of the position shown is fixed to the upper part of the second support Ⅱ22 of the water retaining curtain by means of a tension spring fixing screw 24121 at a position corresponding to the tension spring fixing hole Ⅱ222 of the second support of the water retaining curtain. A locking nut 24122 is provided at the end of the tension spring fixing screw 24121. Since the fixation of the first tension spring 2411 and the first support Ⅰ21 of the water retaining curtain is similar to that of the second tension spring 2412, it will not be repeated here.

[0034] In this embodiment, the aforementioned water curtain 24 is a non-metallic film and has a corrugated cross-sectional shape, which is more vividly described as the shape of a corrugated tile seen in daily life. Since the upper part of the water curtain 24 is penetrated by the water curtain suspension rope 2413, the lower part, i.e., the lower edge, is supported on a set of support plates 16 in the warp stop bars. More specifically, the lower part, i.e., the lower edge, of the water curtain 24 contacts the support plates 16 in the warp stop bars, but is not fixed. Therefore, when the warp yarn breaks and the machine needs to be connected, the water curtain 24 can be opened or closed like a curtain. When opened, the two sides of the water curtain 24 are gathered in the direction of the middle column 23 of the water curtain, and vice versa. After the water curtain 24 is opened, the machine operator can conveniently handle the broken warp yarn (connect the broken warp yarn). After the broken warp yarn is processed, i.e., the connection is completed, the water curtain 24 is closed, so that the water curtain 24 is unfolded in the direction away from the middle column 23 of the water curtain.

[0035] In this embodiment, the non-metallic 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 also be used.

[0036] The present invention is installed on a water jet loom in the category of shuttleless looms. The water splashed out by the water jet loom during operation can be blocked by the water retaining curtain 24 and will not splash onto the warp stop bar junction box 11 and a group of warp stop bars 12, thereby ensuring the normal warp breaking response action of the warp stop frame assembly 1. Since the working principle of the warp stop frame assembly 1 is basically the same as the well-known warp stop frame mentioned by the applicant in the background technology column above, the applicant will not elaborate on it.

[0037] In summary, the innovative application of the warp stop frame assembly 1 to the water jet loom in conjunction with the water retaining curtain mechanism 2 has made up for the shortcomings of the prior art, successfully completed the invention task, and faithfully achieved the technical effects recorded by the applicant in the technical effect column above.
