Description

Technical Field

[0001] The invention belongs to the technical field of spinning equipment accessories, and in particular relates to a drop bar middle bracket. Background Art

[0002] The aforementioned warp stop bar bracket is an auxiliary component of the warp stop frame. When in use, it is fixed on the warp frame to support the warp stop bar, prevent the long warp stop bar from deflecting, and stabilize the warp stop bar, for example, keep the parallel distance between adjacent warp stop bars consistent. The function of the aforementioned warp stop bar is to pass through the warp drop plate, each of which passes a warp yarn, and the warp yarn makes the warp drop plate suspended on the warp stop bar, so that the core and the iron package of the warp stop bar are in a non-conductive state (the core and the iron package are usually separated by an insulating package such as insulating paper). During the weaving process of the loom, when the warp yarn passing through a certain dropper breaks, the yarn loses the control of the dropper, causing the dropper, which was originally in a suspended state, to fall onto the dropper bar, thereby connecting the chip with the iron clad. The dropper bar junction box on the dropper frame feeds back the signal to the electrical control device of the loom, causing the loom to stop. The loom will resume work after the worker connects the broken warp yarn. It can be seen that the dropper is an indispensable component for the protection of warp yarn breakage. Otherwise, if the loom works normally after the warp yarn breaks, the woven fabric will be defective.

[0003] From the above description, it can be seen that the warp stop bar is an indispensable auxiliary component of the warp stop frame, and further, it can be seen that the warp stop frame is an indispensable and important component of the loom. For technical information and functions of the warp stop frame, please refer to Chinese patent authorization announcement numbers CN2315126Y (warp stop frame), CN2425097Y (warp stop frame), CN202954203U (warp stop frame), CN201169671Y (loom with warp yarn splitting device), CN201439558U (warp stop device for loom) and CN103061010B (warp stop frame). In addition, there is no lack of technical information on warp stop frames in foreign patents, such as DE4142456A1 and NL8600372A, etc.

[0004] Technical information on the support in the stop bar can also be found in the public Chinese patent documents, such as the "support plate structure in the stop bar" recommended by CN104372505A. This patent can objectively realize the technical effects recorded in the technical effect column of its specification, but it still has the following shortcomings: First, since the support in the stop bar tends to be a flat structure and is made of plastic with relatively poor rigidity, and since the stop bar is a narrow strip, the vibration generated when the loom is in operation will more or less cause the stop bar to vibrate accordingly. When the stop frame vibrates, the support in the stop bar will also vibrate accordingly. Especially when the vibration is severe (such as when the loom is working at high speed), the stop bar will touch the drop plate, causing an abnormal shutdown. After long-term analysis, the applicant believes that the effect of limiting the warp bar bracket at the lower side of the warp bar bracket by only relying on a warp yarn frame corresponding to each side of the warp bar bracket is very limited; secondly, although the two ends of a group of warp bars can be positioned by the warp bar terminal box and the fixing seat respectively, the length of the warp bar is relatively long. For example, the wider the fabric width, the longer the warp stop frame is, and the length of the warp bar is also correspondingly longer, while the middle part of the warp bar is merely placed on the upper opening part, that is, the warp bar whose upper part is connected to the outside world. The support groove cannot restrain the up and down jumping of the warp stop bar. When the up and down jumping of the warp stop bar exceeds a reasonable range, the warp stop plate will be touched, which will also cause the loom to stop abnormally, that is, not when the warp is broken. Thirdly, since the components of the entire support bar are all molded by plastic, and since the support bar is generally considered to be a consumable part, it is usually replaced as a whole after aging and / or damage. Therefore, on the one hand, it increases the cost of textile equipment accessories for fabric manufacturers, that is, manufacturers using the warp stop frame, and on the other hand, it causes a waste of resources.

[0005] In view of the fact that the above situation is not limited, it is necessary to make improvements. For this purpose, the applicant has made a lasting and beneficial design, forming the technical solution to be introduced below, and it has been proved to be feasible through computer simulation tests under confidentiality measures.

The number of the group of warp stop bars 54 in this application example is four because Figure 1 The number of the drop bar support grooves 31 formed on the drop bar support plate 3 is four (four), but it is obvious that it should not be limited to the aforementioned number. The middle part of a group of drop bars 54 is placed in the drop bar support grooves 31 of the drop bar support plate 3 of the structural system of the drop bar bracket of the present invention, and the two ends of a group of drop bars 54 are respectively inserted into a pair of drop bar end electrical junction boxes 51, that is, the two ends of a group of drop bars 54 are positioned by a pair of drop bar end electrical junction boxes 51 and a group of drop bars 54 are electrically connected to a pair of drop bar end electrical junction boxes 51, and the pair of drop bar end electrical junction boxes 51 are electrically connected to the electrical control box of the loom through electrical connection lines 511 (also called "power and signal lines") when in use.

Figure 1 The two sides of the structure are as follows, for example, the left and right sides, and the middle of the pair of yarn guide rods 53 is positioned between the aforementioned yarn guide rod matching cavity 211 and the U-shaped frame arm fixing seat yarn guide rod matching cavity 4122, and the two ends of the pair of yarn guide rods 53 are respectively inserted into a pair of end seat yarn guide rod holes 561 (preset on the spacer end seat 56) Figure 3 The number of a group of spacers 55 is equal to the number of the aforementioned spacer support grooves 32 (three in this embodiment), and the two ends of the group of spacers 55 are also inserted into the spacer embedding grooves 562 (preset on the aforementioned pair of spacer end seats 56) Figure 3 The fixing method of a pair of half-axle fixing seats 57 is the same. Figure 3 The indicated area is located Figure 2 A half-axle fixing seat 57 at the rear side has a half-axle fixing hole 571 formed on the half-axle fixing seat 57.

[0039] The reason why a pair of first screw holes Ⅰ574, a pair of second screw holes Ⅱ575, a pair of third screw holes Ⅲ576 and a pair of fourth screw holes Ⅳ577 are respectively provided on the aforementioned pair of half-shaft fixing seats 57 is that a pair of first screw holes Ⅰ574, a pair of second screw holes Ⅱ575, a pair of third screw holes Ⅲ576 and a pair of fourth screw holes Ⅳ577 of the half-shaft fixing seats are provided on the aforementioned pair of half-shaft fixing seats 57 because a pair of first screw holes Ⅰ574, a pair of second screw holes Ⅱ575, a pair of third screw holes Ⅲ576 and a pair of fourth screw holes Ⅳ577 of the half-shaft fixing seats 57 are provided on the aforementioned pair of half-shaft fixing seats 57 because a pair of first screw holes Ⅰ574, a pair of second screw holes Ⅱ575 and a pair of third screw holes Ⅲ576 and a pair of Figure 2 The pair of warp stop frame assemblies 5 shown in the figure, and the installation direction of the pair of half-shaft fixing seats 57 of one of the pair of warp stop frame assemblies 5 is turned 180° relative to the installation direction of the half-shaft fixing seat 57 of the previous warp stop frame assembly 5, and when turned 180°, the third screw hole III 576 of the pair of half-shaft fixing seats and the fourth screw hole IV 577 of the pair of half-shaft fixing seats are activated. In addition, according to professional common sense and according to the above description of the applicant, since there is a pair of yarn guide rods 53 involved, it is shown that the present invention Figure 1 The structure is used in a towel knitting machine, because the towel cloth has a surface structure and a bottom structure, and the yarn guide rod 53 guides the warp yarn of the towel. If it is not used for weaving towel cloth, the aforementioned yarn guide rod 53 can be omitted. However, no matter how the fabric changes, as long as the bracket in the warp drop bar structure of the present invention is used, it should be regarded as the technical connotation scope disclosed by the present invention.

[0040] There are two ways to continue the warp after the warp yarn is exhausted: one is warp tying; the other is to transfer a group of drop bars 54 to the warp drawing station. For the first warp tying, there is no need to release the positioning of the ends of a group of drop bars 54 by the pair of drop bar end electrical junction boxes 51, and there is no need to subsequently release the blocking of the upper open parts of the drop bar support grooves 31 and the spacer support grooves 32 by the drop bar anti-jump mechanism 4. For the second warp drawing, first release the positioning of the two ends of a group of drop bars 54 by the pair of drop bar end electrical junction boxes 51, then loosen the screws 4121 of the slit frame arm fixing seat, remove the slit frame 41 together with the buffer pad 42, install the group of drop bars 54 that have been previously drawn in, and then position the position of the group of drop bars 54 by the pair of drop bar end electrical junction boxes 51, and return the slit frame 41 together with the buffer pad 42.

[0041] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
