Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, and in particular to a warp break automatic stop device for a water jet loom. Background Art

[0002] Water jet looms are favored by textile enterprises for their advantages such as high speed, low noise and high efficiency. In the process of weaving with water jet looms, if polyester staple yarn is used as warp yarn, due to the problems of uneven strength, weak twist and hairiness of polyester staple yarn, warp breakage will often occur during the weaving process. The occurrence of warp breakage will cause broken warp defective fabrics, increase the downtime and labor intensity of the machine operator, reduce the operation efficiency and production efficiency of the equipment, and thus lead to reduced output and waste of defective fabrics.

[0003] Chinese patent CN102383248A discloses a high-sensitivity warp break and warp completion automatic stop device for a circular loom, comprising a hanger, a detector, and a signal device. The hanger and the detector are installed between the creel and the jumper, and the hanger is hung between the threading plates or between the threading plates and the rollers (rods) or between the rollers (rods). The hanger is in sliding or rolling contact with the warp. When the warp is broken or used up, the hanger immediately droops and contacts the detector or is picked up, and the machine is immediately stopped and a signal is sent. Although this structure can detect the breakage of the wire at the first time and make a shutdown response in time, it can effectively overcome the fault of a large piece of warp being broken due to the breakage of a warp, but it is implemented by using a detector, such as a photoelectric probe, which has a large investment in cost and has a relatively high position requirement. The structure of the warp stop ruler is too complicated, which also invisibly increases the production cost.

[0004] Therefore, it is necessary to invent a novel warp break automatic stop device for water jet loom to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a warp break automatic stop device which can be installed on different water jet looms, and the warp break automatic stop device can ensure that the loom stops immediately when warp break occurs during the weaving process.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: A warp-break automatic stop device for a water jet loom, characterized in that it comprises a warp-stop box fixture, a warp-stop box, a warp-stop power supply, a warp-stop bar, a warp-stop sheet, a water retaining bracket and a waterproof cloth; the warp-stop box fixture and the warp-stop power supply are arranged on the warp-stop box, the warp-stop bar is passed through the warp-stop box and is fixed by the warp-stop box fixture; the warp-stop sheet is provided with a through hole, each yarn passes through each through hole of the warp-stop sheet, the warp-stop sheet is arranged on the warp-stop bar, and when the yarn breaks during the manufacturing process, the warp-stop sheet loses the support of the yarn and falls down to form a circuit break; The water retaining bracket is arranged on the outer periphery of the warp dropper, and the waterproof cloth is fixed on the water retaining bracket to prevent water mist from being sprayed onto the warp dropper and causing a circuit breaker.

[0007] The beneficial effects of the present invention are: The present invention transforms water-jet looms of different models and adds a warp break automatic stop device. When a warp break occurs during the weaving process, the loom stops immediately, thereby reducing the generation of warp break defective cloth. After the warp break automatic stop device is installed, the cloth surface quality is greatly improved, there is no break defect on the cloth surface, and the loom stops immediately when a warp break occurs, which solves the problem of continuous stopping when the warp breaks and the broken yarns are entangled with each other, and speeds up the time for the loom worker to deal with the broken yarn. At the same time, the efficiency of the loom is improved by 20 percentage points on the original basis, reaching more than 93%; the automatic stop device has a simple structure, low cost, good stability, and is easy to use and popularize.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] See also Figure 1 As shown, a warp stop automatic stop device for a water jet loom shown in a preferred embodiment of the present application includes a warp stop box fixture 1, a warp stop box 2, a warp stop power supply 3, a warp stop bar 4, a warp stop plate 5, a water retaining bracket 6 and a waterproof cloth 7; the warp stop box fixture 1 and the warp stop power supply 3 are arranged on the warp stop box 2, the warp stop bar 4 is passed through the warp stop box 2 and is fixed by the warp stop box fixture 1; the warp stop plate 5 is provided with a through hole, each yarn passes through the through hole of each warp stop plate 5, and when the yarn breaks during the manufacturing process, the warp stop plate 5 loses the support of the yarn and falls down to form a circuit break, and the warp stop plate 5 is arranged on the warp stop bar 3.

[0016] The outside of the device is also wrapped with a waterproof cloth 7, which is fixed on a water retaining bracket 6 to prevent water mist from spraying onto the dropper piece 5 and causing a circuit breaker.

[0017] The working principle of the present invention is: During the weaving process of the loom, the warp yarn is unwound from the weaving beam, passes through the back beam---warp stop device---heald---reed to the cloth mouth to form the cloth surface. During this movement, the warp yarn is affected by the tension of the loom, the friction of the warp stopper, heald, reed and the strong unevenness of the polyester staple fiber, which may cause the warp yarn to break. When the warp yarn breaks, there is no tension. The warp stopper will fall on the warp stopper due to its own weight, causing a short circuit through the warp stopper, thereby stopping the equipment automatically and effectively preventing the production of broken warp defective cloth.

[0018] In summary, the present invention transforms water-jet looms of different models and adds a warp break automatic stop device. When a warp break occurs during the weaving process, the loom stops immediately, thereby reducing the production of warp break defective cloth. After the installation of the warp break automatic stop device, the cloth quality is greatly improved, there is no break defect on the cloth surface, and the loom stops immediately when a warp break occurs, which solves the problem of continuous stopping when the warp breaks and the broken yarns are entangled with each other, and speeds up the time for the loom worker to deal with the broken yarn. At the same time, the efficiency of the loom is improved by 20 percentage points on the original basis, reaching more than 93%; the automatic stop device has a simple structure, low cost, good stability, and is easy to use and promote.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0020] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
