Description

Technical Field

[0001] The utility model relates to the technical field of line break automatic stop, in particular to a line break automatic stop device. Background Art

[0002] In the textile industry, the thread breakage stop device is usually called a yarn breakage detection device, which is used to detect whether the yarn in the spinning machine or loom is broken or broken, so as to avoid the situation that the yarn continues to run after the breakage, which may cause quality problems or machine failure. The thread breakage stop device can be applied to the spinning or weaving process of various fibers, such as cotton yarn, wool yarn, polyester yarn, etc. They can effectively prevent the problems such as yarn interlacing, spinning distortion, uneven texture, etc. caused by the continued operation after the yarn breaks, thereby improving production efficiency and product quality.

[0003] Yarn breakage or other problems are common in the warping process. These problems will have an adverse effect on the quality and efficiency of warping. Yarn breakage causes missing or misaligned warping layout, affecting the appearance quality and performance of woven products. Broken yarns will leave missing bearings or weaving marks, forming obvious defects on the fabric. If the broken yarn is not discovered in time, the problem will continue throughout the weaving process, resulting in multiple yarn breakage points, further affecting the uniformity and integrity of warping. Therefore, it is necessary to develop a broken thread automatic stop device. Utility Model Content

[0004] The purpose of the utility model is to provide a wire breakage automatic stop device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire breakage automatic stop device, comprising a mounting frame, an automatic stop mechanism and a wire feeding mechanism;

[0006] The self-stop mechanism is fixed to the inner wall of the mounting frame, the inner wall of the mounting frame is fixedly connected with a shell, a sliding groove is opened on the top of the shell, a connecting tube is inserted into the sliding groove, the lower end of the connecting tube is fixedly connected with a rotating tube, the rotating tube is sleeved on the outer side of the fixed column, the two ends of the fixed column are fixedly connected to the inner wall of the mounting frame, the bottom end of the shell is fixedly connected with a pressure sensor, and the wire feeding mechanism is arranged inside the mounting frame; the self-stop mechanism also includes a pressure sensor, which is fixedly connected to the bottom end of the inner wall of the shell, and the plane where the highest point of the pressure sensor is located is lower than the plane where the lowest point of the connecting tube is located; the wire feeding mechanism includes a wire inlet tube, which passes through and is fixed inside the mounting frame, and the wire inlet tube is used to limit the transmission trajectory of the yarn; the wire feeding mechanism also includes a mounting sleeve, and the middle of the mounting sleeve is rotatably connected with a driving tube.

[0007] By adopting the above technical scheme, the yarn is first passed through the connecting tube on the rotating tube. Due to the tension of the yarn, the connecting tube is driven into a vertical axis shape. When the yarn breaks, the connecting tube will cause the rotating tube connected to the connecting tube to rotate around the fixed column due to the influence of gravity, so that the connecting tube will contact the pressure sensor. When the pressure sensor senses the pressure, it will control the drive part to stop, thereby achieving the effect of self-stopping when the yarn is broken, thereby avoiding the situation where the warping is uneven and incomplete due to the broken yarn. When the pressure sensor is under pressure, it will transmit a signal to the control mechanism, thereby controlling the equipment to stop working, and transporting the yarn to the equipment through the inlet tube on the mounting frame. The inlet tube reduces the probability of the yarn breaking during transportation, thereby reducing the probability of damage during the warping process. At the same time, the driving tube rotates in the mounting sleeve, so that the yarn can be transported.

[0008] Preferably, a wire feeding channel is opened on the outer side of the driving tube, and the wire feeding channel is used to transmit the yarn.

[0009] By adopting the above technical solution, the yarn is limited by the wire feeding channel, so as to avoid the yarn shifting during wire feeding, thereby preventing the yarn from getting tangled together and affecting the uniformity of warping.

[0010] Preferably, the mounting frame includes two fixing plates, the inner wall between two adjacent fixing plates is fixed to two ends of the mounting plates, and the mounting plates and the driving tube are distributed in parallel at the top ends of the fixing plates.

[0011] By adopting the above technical solution, the device can be conveniently fixed by the fixing plates on both sides of the mounting plate, thereby facilitating the operation of the device.

[0012] Preferably, the fixing plate is located on the outer wall of the limiting tube and is fixedly connected with a driving part, and the driving part is used to drive the limiting tube and the driving tube to rotate.

[0013] By adopting the above technical solution, the driving tube can be rotated by the driving part to transport the yarn, and the connecting tube can be limited by the limiting tube to avoid changes in the tension of the yarn transportation, thereby affecting the uniformity of the warping.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting up a self-stop mechanism, the yarn is first passed through the connecting tube on the rotating tube. Due to the tension of the yarn, the connecting tube is driven into a vertical axis shape. When the yarn is broken, the connecting tube will cause the rotating tube connected to the connecting tube to rotate around the fixed column due to the influence of gravity, so that the connecting tube will contact the pressure sensor. When the pressure sensor senses the pressure, it will control the driving part to stop working, thereby achieving the effect of self-stopping when the yarn is broken, so as to avoid the situation that the yarn should be broken and cause uneven and complete warping;

[0016] 2. The yarn is transported to the device through the wire feeding tube on the mounting frame by providing a wire feeding mechanism. The wire feeding tube reduces the probability of yarn breakage during transportation, thereby reducing the probability of damage during warping. The driving tube rotates in the mounting sleeve, so that the yarn can be transported and the yarn can be limited through the wire feeding channel, thereby avoiding the yarn shifting during wire feeding, thereby preventing the yarn from getting tangled together and affecting the uniformity of warping.

[0017] 3. By setting a limit tube, the connecting tube is limited by the limit tube, so as to avoid changes in the tension of yarn transportation, thereby affecting the uniformity of warping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The following is combined with Figure 1-4 The utility model is described in further detail.

[0025] Example 1

[0026] See also Figure 1 and Figure 2 , the utility model provides a technical solution: a yarn breaking automatic stop device, comprising a mounting frame 1, an automatic stop mechanism 2 and a wire feeding mechanism 3;

[0027] The automatic stop mechanism 2 is fixedly mounted on the inner wall of the mounting frame 1, wherein the mounting frame 1 is a rectangular frame, which provides assembly conditions for the components of the entire broken yarn automatic stop device, and the inner wall of the mounting frame 1 is fixedly connected with a shell 201, wherein the bottom of the shell 201 is rectangular in design, and the top is arc-shaped in design, the middle of the shell 201 is hollow in design, and both ends of the shell 201 are fixedly connected to the inner wall of the mounting frame 1, and a sliding groove 205 is provided on the top of the shell 201, and a connecting tube 204 is inserted into the sliding groove 205, and the connecting tube 204 is composed of a hollow cylinder and a rectangle, and the cylinder is located at the top of the rectangle, and the lower end of the connecting tube 204 is fixedly connected with a rotating tube 203, and the rotating tube 203 is sleeved on the outer side of the fixed column 202, wherein only one fixed column 202 is provided, and the fixed column 202 is a cylindrical design The connecting tube 204 and the fixed column 202 are designed in concentric circles, and the connecting tube 204 rotates and swings around the center of the fixed column 202 in the arc-shaped part at the top of the shell 201. The two ends of the fixed column 202 are fixedly connected to the inner wall of the mounting frame 1, and the bottom end of the inner wall of the shell 201 is fixedly connected with a pressure sensor 206, wherein the pressure sensor 206 is located directly below the sliding groove 205 when in use, so as to ensure that the connecting tube 204 is used in conjunction with the pressure sensor 206 when rotating. The pressure sensor 206 is a device or apparatus that can sense a pressure signal and convert the pressure signal into a usable output electrical signal. The above is the public technology of the pressure sensor 206, which will not be repeated below. The wire feeding mechanism 3 is arranged inside the mounting frame 1, and the yarn can be transported through the wire feeding mechanism 3.

[0028] First, the yarn is passed through the connecting tube 204 on the rotating tube 203. Due to the tension of the yarn, the connecting tube 204 will be driven into a vertical axis shape. When the yarn breaks, the connecting tube 204 will be driven to rotate due to the influence of gravity. The rotating tube 203 will rotate around the fixed column 202 at this time, limiting the rotation trajectory of the connecting tube 204, so that the connecting tube 204 contacts the pressure sensor 206. When the pressure sensor 206 senses pressure, it will control the equipment to stop working, thereby achieving the effect of self-stopping when the yarn breaks, thereby avoiding the situation where the warping is uneven and incomplete due to the broken yarn.

[0029] Example 2

[0030] See also Figure 1 and Figure 3 , a yarn breaking automatic stop device, comprising a wire feed tube 301, a drive tube 302, a wire feeding channel 303 and a mounting sleeve 304;

[0031] The wire inlet tube 301 passes through and is fixed inside the mounting frame 1. The yarn is transported to the equipment through the wire inlet tube 301 on the mounting frame 1. The wire inlet tube 301 reduces the probability of the yarn breaking during transportation, thereby reducing the probability of damage during the warping process. A mounting sleeve 304 is welded to the inner wall of the mounting frame 1. A driving tube 302 is rotatably connected in the mounting sleeve 304. The driving tube 302 rotates in the mounting sleeve 304, so that the yarn can be transported. A wire feeding channel 303 is opened on the outside of the driving tube 302. The wire feeding channel 303 is used to limit the yarn to avoid displacement of the yarn during feeding, entanglement, and affecting the uniformity of the warping.

[0032] When the device is in operation, the yarn is transported in the wire feeding channel 303 inside the wire inlet tube 301 and outside the drive tube 302, which reduces the probability of yarn displacement and entanglement during transportation and improves the uniformity of warping.

[0033] Example 3

[0034] Please refer to Figure 1 and Figure 4 As shown, a yarn breaking automatic stop device also includes a driving part 4, a fixing plate 101, a mounting plate 102 and a limiting tube 103;

[0035] The inner walls of two adjacent fixed plates 101 are welded with mounting plates 102, and the mounting plates 102 and the fixed plates 101 provide assembly conditions for the parts of the wire feeding mechanism 3. The inner walls of the two adjacent fixed plates 101 are rotatably connected to the limiting tube 103, and the limiting tube 103 can limit the height of the yarn transportation, so that the tension during yarn transportation reaches the maximum. The inner walls of the two adjacent fixed plates 101 are rotatably connected to the driving tube 302, and the driving tube 302 is rotated in the mounting sleeve 304 to transport the yarn. The fixed plate 101 is located on the outer wall of the limiting tube 103 and is fixedly connected to a driving part 4, and the driving part 4 is used to drive the limiting tube 103 and the driving tube 302, wherein the driving part 4 includes a driving motor, a driving wheel fixed on one side of the limiting tube 103, and a secondary driving wheel fixed on one side of the driving tube 302, and the driving wheel and the secondary driving wheel are both provided with tooth surfaces, and the driving wheel and the secondary driving wheel are meshed with the tooth surfaces and the belt chain.

[0036] When in use, the main gear and the secondary gear are driven to rotate by the driving motor, thereby rotating the limiting tube 103 and the driving tube 302, and limiting the connecting tube 204 by the limiting tube 103, thereby avoiding changes in the tension of the yarn transportation and transporting the thread.

[0037] Working principle: First, the yarn is transported to the equipment through the inlet tube 301 on the mounting frame 1, and the yarn is passed through the connecting tube 204 on the rotating tube 203, and the yarn is bypassed by the wire feeding channel 303 on the driving tube 302. Due to the tension of the yarn, the connecting tube 204 is driven into a vertical axis shape, and the limiting tube 103 limits the connecting tube 204, thereby avoiding changes in the tension of the yarn transportation; secondly, when the yarn breaks, the connecting tube 204 will cause the rotating tube 203 connected to the connecting tube 204 to rotate around the fixed column 202 due to the influence of gravity, so that the connecting tube 204 will contact the pressure sensor 206. When the pressure sensor 206 senses the pressure, it will control the driving unit 4 to stop working, thereby achieving the effect of self-stopping when the yarn breaks, thereby avoiding the situation where the warping is uneven and incomplete due to the broken yarn.
