Description

Technical Field

[0001] This utility model relates to the field of anti-collision device technology, specifically to an anti-collision device for the yarn conveyor belt of an air-jet spinning machine. Background Technology

[0002] Air-jet spinning machines, also known as rotor spinning machines, are one of the core pieces of equipment in the textile industry. They use high-speed rotating rotors to coagulate fibers into yarn and directly wind it into cones. They are characterized by high spinning speed, high output, and high degree of automation, and are widely used in the large-scale production of short fibers such as cotton, wool, and chemical fibers. In the production process of air-jet spinning machines, the cone conveyor belt is a key transmission system connecting the spinning station with subsequent processes such as winding, quality inspection, and packaging. Its function is to smoothly and accurately transport the freshly wound cones from the spinning cup to the next stage, directly affecting the continuity of production, the integrity of the cones, and the quality of the yarn.

[0003] Traditional yarn conveyor belts lack protective equipment and only provide simple conveying. However, the formed yarn may become unstable on the conveyor belt, such as colliding with each other or rolling off the belt after being knocked over, which affects the continuity of production and reduces the effectiveness and practicality of the equipment. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an anti-collision device for the yarn conveyor belt of an air-jet spinning machine. It solves the problem that the traditional yarn conveyor belt in the prior art lacks protective equipment and only has a simple conveying effect. However, the formed yarn may be unstable on the conveyor belt, such as the yarn colliding with each other or rolling off the conveyor belt after being knocked over, which affects the continuity of production and reduces the effectiveness and practicality of the equipment.

[0005] According to one aspect, at least one embodiment of the present invention provides an anti-collision device for the yarn conveyor belt of an air-jet spinning machine, comprising a device body, wherein fixing rods are fixedly installed on the top of the device body near the four corners, and further comprising:

[0006] A transmission component, wherein the transmission component is disposed between the two interior sides of the main body of the device;

[0007] A partition plate, wherein multiple partition plates are provided, and all multiple partition plates are fixedly arranged at equal intervals along the outer surface of the transmission component;

[0008] The protective components are provided in two parts, and both protective components are rotatably connected to the fixed rod.

[0009] For example, the transmission component includes a motor, which is fixedly mounted on one side of the device body near the rear edge. Rotating rods are rotatably mounted between the inner walls of both sides of the device body near the front and rear sides. One end of one of the rotating rods is fixedly welded to the output end of the motor. Synchronous pulleys are fixedly sleeved on the outer surfaces of both rotating rods, and a synchronous belt is meshed between the outer surfaces of the two synchronous pulleys.

[0010] For example, the plurality of partition plates include partition bases, and the plurality of partition bases are fixedly arranged at equal intervals along the outer surface of the timing belt, and a first partition is fixedly arranged at the top center of the plurality of partition bases near the front side.

[0011] For example, the top of the multiple partition bases is provided with horizontal sliding grooves near both sides, and fixed sliding rods are fixedly provided between the inner surface walls of the multiple sliding grooves. Sliding blocks are slidably sleeved on the outer surface of the multiple fixed sliding rods. Second partitions are fixedly provided on the top of each pair of sliding blocks. First springs are sleeved on the outer surface of the multiple fixed sliding rods, and one end of the first spring is fixedly welded to one side of the sliding groove, and the other end is fixedly welded to one side of the sliding block.

[0012] For example, each pair of the second partitions has an installation groove on its opposite side, and a transmission roller is movably sleeved between the upper and lower inner walls of the multiple installation grooves via a fixed short rod.

[0013] For example, the two protective components include connecting plates, each of which is rotatably sleeved on the outer surface of two fixed rods near the rear side. A protective plate is fixedly connected to the opposite end of each of the two connecting plates, and an ear bracket is fixedly installed on the opposite side of each of the two protective plates near the front side.

[0014] For example, each of the two ear brackets has a first ear block rotatably mounted inside, and each of the two first ear blocks has a telescopic rod fixedly connected to one of its opposite ends, and each of the two telescopic rods has a second ear block fixedly connected to one of its opposite ends.

[0015] For example, a second spring is fitted on the outer surface of both telescopic rods. One end of the second spring is fixedly welded to the first lug and the other end is fixedly welded to the second lug. The two second springs are respectively rotatably fitted on the outer surface of two of the fixed rods near the front side.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] In this invention, the program is first set up via PLC, allowing the yarn bobbins to be placed on the transmission component. When the transmission component is activated, it drives the partition plates synchronously. The pushing action of the partition plates ensures stable transmission of the yarn bobbins. Multiple partition plates separate each yarn bobbin during transmission, preventing collisions. The relative arrangement of two protective components in a funnel shape reduces the distance between the sides of the transmitted yarn bobbins, making the conveying process more stable and preventing tipping. This avoids collisions between yarn bobbins or them rolling off the conveyor belt after a fall, improving the equipment's performance and practicality. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-2As shown, this invention illustrates an anti-collision device for the yarn conveyor belt of an air-jet spinning machine according to an embodiment of the present invention. The device includes a main body 1, with fixing rods 4 fixedly installed at the top of the main body 1 near each of the four corners. It also includes:

[0033] Transmission component 2 is disposed between the two sides inside the main body 1 of the device;

[0034] Partition plate 3, multiple partition plates 3 are provided, and multiple partition plates 3 are fixedly arranged at equal intervals along the outer surface of the transmission component 2;

[0035] There are two protective components 5, and both protective components 5 are rotatably connected to the fixed rod 4.

[0036] In this embodiment, the program is first set by the PLC, and the yarn bobbins can be placed on the transmission component 2. When the transmission component 2 is started, it can drive the partition plate 3 to move synchronously. The pushing of the partition plate 3 can drive the yarn bobbins to be transmitted stably. Multiple partition plates 3 can separate each yarn bobbin in the transmission to avoid collisions between yarn bobbins during transportation. The relative arrangement of the two protective components 5 in a funnel shape makes the movement distance on both sides of the transmitted yarn bobbin smaller and smaller, making the yarn bobbin conveying process more stable and less prone to tipping.

[0037] like Figures 1-5 As shown, the transmission component 2 and partition plate 3 are shown in another embodiment of the present invention. The transmission component 2 includes a motor 21, which is fixedly installed on one side of the device body 1 near the rear edge. Rotating rods 22 are rotatably installed between the inner walls of both sides of the device body 1 near the front and rear sides. One end of one of the rotating rods 22 is fixedly welded to the output end of the motor 21. Synchronous pulleys 23 are fixedly sleeved on the outer surfaces of both rotating rods 22. Synchronous belts 24 are meshed between the outer surfaces of the two synchronous pulleys 23.

[0038] Multiple partition plates 3 include partition bases 31, which are equidistantly fixed along the outer surface of the synchronous belt 24. A first partition plate 32 is fixedly installed at the top center of each partition base 31 near the front side. A sliding groove 33 is laterally opened on the top of each partition base 31 near both sides. A fixed sliding rod 34 is fixedly installed between the inner walls of the two sides of the sliding groove 33. A slider 35 is slidably sleeved on the outer surface of each fixed sliding rod 34. A second partition plate 36 is fixedly installed on the top of each pair of sliders 35. A first spring 37 is sleeved on the outer surface of each fixed sliding rod 34. One end of the first spring 37 is fixedly welded to one side of the sliding groove 33, and the other end is fixedly welded to one side of the slider 35. An installation groove 38 is opened on the opposite side of each pair of second partition plates 36. A transmission roller 39 is movably sleeved between the upper and lower inner walls of the multiple installation grooves 38 through a fixed short rod.

[0039] In this embodiment, when the motor 21 starts, it can drive one of the rotating rods 22 to rotate synchronously with the synchronous pulley 23. The synchronous belt 24 ensures that the two synchronous pulleys 23 can rotate synchronously, guaranteeing stable transmission. During transmission, the partition base 31, the first partition 32, and the second partition 36 assist in the transmission of the yarn packages and also act as partitions, preventing collisions between the yarn packages. The first partition 32 and the second partition 36 increase the height of the partition base 31, improving efficiency. To achieve the separation effect, the rotation of the drive rollers 39 causes the second partitions 36 on both sides to retract inward when they contact the protective component 5. Under the sliding arrangement of the slide groove 33 and the slider 35, the two second partitions 36 retract inward, simultaneously causing the first spring 37 to contract inward synchronously. When the partition base 31 moves to the lower half of the synchronous belt 24, the reverse stretching force of the first spring 37 causes the sliders 35 and the second partitions 36 on both sides to quickly slide outward and reset, waiting for the next cycle.

[0040] like Figures 1-6As shown, a protective component 5 is illustrated in another embodiment of the present invention. The two protective components 5 include connecting plates 51. Each connecting plate 51 is rotatably sleeved on the outer surface of one of the two fixed rods 4 near the rear side. A protective plate 52 is fixedly connected to the opposite end of each of the two connecting plates 51. Ear brackets 53 are fixedly installed on the opposite side of each of the two protective plates 52 near the front side. A first ear block 54 is rotatably installed inside each of the two ear brackets 53. A telescopic rod 55 is fixedly connected to the opposite end of each of the two first ear blocks 54. A second ear block 56 is fixedly connected to the opposite end of each of the two telescopic rods 55. A second spring 57 is sleeved on the outer surface of each of the two telescopic rods 55. One end of the second spring 57 is fixedly welded to the first ear block 54, and the other end is fixedly welded to the second ear block 56. The two second springs 57 are rotatably sleeved on the outer surface of one of the two fixed rods 4 near the front side.

[0041] In this embodiment, the relative arrangement of the two protective plates 52 makes the movement distance on both sides of the yarn bobbin smaller and smaller during the transmission process, making the yarn bobbin conveying process more stable and less prone to tipping. When the partition base 31 slides to the angle between the two protective plates 52, the second partition 36 on both sides overlaps with the first partition 32. At this time, the width after the overlap is larger than the diameter of the yarn bobbin. Through the continuous transmission of the partition base 31, the two protective plates 52 will be pushed outward by the transmission rollers 39 on both sides, while the telescopic rod 55 and the second spring 57 will be driven to retract inward. This avoids the two protective plates 52 squeezing the yarn bobbin and causing it to deform, thus improving the use effect and practicality of the equipment. After the transmission of one yarn bobbin is completed, the telescopic rod 55 and the protective plate 52 will be quickly reset by the reverse stretching force of the second spring 57.
