Description

Warp stop box structure of warp stop frame

Technical Field

The invention belongs to the technical field of loom accessories, and particularly relates to a warp stop box structure of a warp stop frame.

Background

Such as rapier looms, air jet looms, and the like. As is known in the art, the function of a drop frame is to provide drop bars, the function of which is to pass through drop wires, each (i.e. "each") drop wire being passed through a warp, the warp being such that the drop wire is suspended above the drop bar, and when the drop wire is suspended relative to the drop bar, the structural system of the drop bar is in a non-conductive state (typically separated from the package by an electrically insulating barrier) between the chips and the package. In the weaving process of the loom, when the warp yarn passing through a certain drop wire is broken, namely broken yarn, the suspended tube bundles of the drop wire are lost, so that the drop wire which is in a suspended state is dropped and hung on the drop wire, and an electric loop between the chip and the coated iron is connected, so that a signal is fed back to an electric control device of the loom by a drop box (also called as a drop wire junction box) of the drop wire, the loom is stopped, the broken warp yarn is continued by a worker after the loom is stopped, and the loom resumes work. Therefore, the chip of the warp stop strip is conducted with the iron cladding by the warp stop sheet after the warp is broken to stop immediately, so that the quality of the fabric is ensured, and the defect fabric of the fabric is avoided.

Technical information of the aforementioned drop frames, such as CN2315126Y (drop frame), CN2425097Y (drop frame) and CN202347215U (drop device on water jet loom), etc., is visible in the published chinese patent literature. It is known from reading the aforementioned patent documents, which are not limited to the examples, and combining the common general knowledge: a drop box as mentioned above is usually provided on the aforementioned drop frame, for a typical example of which reference is also made to the "drop frame" recommended by the patent grant publication CN103061010B, the structure of which (the "drop bar junction box" in the patent) and the principle of electrical connection are described in detail in paragraphs 0028 to 0034 of the description of CN 103061010B.

According to the loom conditions and in combination with actual use requirements, in general, one drop frame can meet the setting requirements of six drop wires and can adapt to the setting requirements of eight drop wires, and the design has at least the following advantages: firstly, two specifications (six and eight warp stop strips) are combined into one, so that the manufacturing cost can be saved and the resource can be saved; secondly, the spare parts cost of the textile manufacturer can be reduced; thirdly, the six and eight warp stop strips can be flexibly selected according to requirements, so that the warp stop strip has good adaptability. Of course, there are also drop frames using fourteen drop bars with the sum of six and eight, but this is very rare. When six and eight drop wires are arranged on the general drop wire, the spacing distance between each two adjacent drop wires is about 25.2mm, and when eight drop wires are arranged, the spacing distance between each two adjacent drop wires is about 18mm.

The quality of the fabric is affected to a certain extent by the reliability of the electrical connection between the electrical components in the drop box and the chips of the drop bars, for example, when the drop bars are in poor contact with the chips at one end of the drop box and the contacts of the iron wrap, such as the negative and positive contacts of the power supply, the situation that the chips of the drop bars are conducted with the iron wrap without warning even if the drop wires fall after the warp breaks occurs, and the loom is not stopped because the loom electrical controller does not receive the warp breaking signal from the drop box, thereby generating defective fabrics.

As is clear from the above-described structure of CN103061010B, it can meet the demand of selecting six or eight drop wires (six are shown in the patent, namely, six columns), but there is a disadvantage that the chip and the iron-clad of the drop wires are not in electrical contact with the bottom surface of the signal input contact, because, in order to satisfy the demand of interchangeability, namely, versatility, of six drop wires, when using six drop wires, the chip at one end of the drop wire toward the drop box contacts one end, such as the right end, of the bottom surface of the power contact (the patent is referred to as "signal input contact", hereinafter, the power contact is tilted to the other end, such as the left side, under the force applied to the power contact by the power negative electrode conductive spring, on the one hand, the power contact is stuck in the electrode hole, on the other hand, the overall electrical contact effect of the chip and the power contact is affected, and the aforementioned iron-clad is the same. When eight warp stop strips are used, the positions of the warp stop strips are changed, so that the chip contacts with the other end, such as the left end, of the bottom surface of the power contact, and the power contact is inclined towards the end, such as the right end, which is communicated with the chip, so that the integral electric contact effect of the chip and the power contact is also affected. Therefore, how to make the drop wire box meet the requirement of interchangeability of six and eight drop wires and avoid the problem that the drop wires are in electrical contact with the six drop wires due to the side tilting (namely 'tilting') of the power contacts has long been plagued in the industry and is expected to be solved, but no corresponding technical teaching is found in the middle-outer patent and non-patent documents disclosed so far, and the technical matters to be described below are generated in the background.
