Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a roughness detection device for yarn production. Background Technology

[0002] Yarn is a continuous linear material made from various textile fibers, mainly used for weaving woven fabrics, knitted fabrics, braided fabrics, and some nonwoven fabrics. Yarn can be classified according to different standards, including raw materials, yarn thickness, spinning method, spinning system, yarn structure, and application. For example, according to raw materials, it can be divided into pure spun yarn and blended yarn; according to yarn thickness, it can be divided into coarse yarn, medium yarn, fine yarn, and extra-fine yarn; according to spinning method, it can be divided into ring-spun yarn and free-end yarn (such as air-jet yarn and electrostatic yarn). Accurate detection of yarn roughness is crucial in the yarn production process.

[0003] The existing technology has the following problems: When testing the surface roughness of spun yarn, the testers sample a large number of spun yarns and use instruments to test the surface roughness of the sample to represent the overall surface roughness of the spun yarn. If the test results are poor, it is impossible to adjust the spun yarn in time on the production line, resulting in a large amount of material being wasted. Utility Model Content

[0004] To solve the above-mentioned technical problems, a roughness detection device for yarn production is provided, which solves the problem of a large amount of material being wasted.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A roughness testing device for yarn production includes a base plate. An adjustment assembly, a display plate, a marking plate, a round rod, and a buffer assembly are fixedly mounted on the upper surface of the base plate. These components are linearly distributed from right to left along the edge of the base plate. A rotating shaft is located on the right side of the adjustment assembly and is rotatably connected to the base plate. First support rods are fixedly mounted on both the front and rear sides of the display plate, connecting it to the base plate. Second support rods are fixedly mounted on both the front and rear sides of the marking plate, connecting it to the base plate. A conical groove is formed on the side of the marking plate closest to the round rod, and gypsum board is fixedly mounted on the inner wall of the conical groove.

[0007] Preferably, there are two round rods, which are symmetrically distributed about the center line of the conical groove, and a through groove is provided on the side of the display groove corresponding to the conical groove.

[0008] Preferably, the buffer assembly includes a pneumatic telescopic rod, which is fixedly connected to the base plate. A fixing plate is fixedly installed at one end of the pneumatic telescopic rod away from the base plate. Side plates are fixedly installed on both sides of the fixing plate. A rotating rod is provided between the two side plates and is rotatably connected to both side plates. A spring is sleeved on the outer surface of the pneumatic telescopic rod, and the two ends of the spring are fixedly connected to the surface of the base plate and the bottom surface of the fixing plate, respectively.

[0009] Preferably, the adjustment assembly includes a top plate, with connecting rods fixedly installed on both sides of the top plate. The top plate is fixedly connected to the bottom plate via the connecting rods. A sliding groove is provided on the side of the two connecting rods that are close to each other. A lead screw is rotatably installed on the bottom of the inner wall of the sliding groove. A movable plate corresponding to the sliding groove is provided below the top plate. The movable plate is threadedly connected to both lead screws. A conveying groove is provided through the side of the movable plate.

[0010] Preferably, a limiting plate is fixedly installed on the outer surface of the rotating shaft.

[0011] Preferably, the conical groove is located between two round rods.

[0012] Preferably, buffer plates are fixedly installed on both the upper and lower surfaces of the movable plate.

[0013] Compared with the prior art, the advantages of this utility model are as follows: By setting up a display board, a marking board, and a plasterboard, when the yarn moves in the conical groove of the marking board, the fibers on the surface of the yarn come into contact with the plasterboard. The plasterboard marks the fibers on the surface of the yarn. When the marked fibers pass through the display board, the marks on the surface are left on the side of the display board. The operator can judge the surface roughness of the yarn by observing the marks on the side of the display board, realizing real-time monitoring of the surface roughness of the yarn. If the test result is poor, the production line can be stopped immediately and adjusted to prevent material waste. This utility model also includes an adjustment component.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-4 As shown, a roughness detection device for yarn production includes a base plate 1. An adjustment assembly 2, a display plate 3, a marking plate 4, a round rod 5, and a buffer assembly 6 are fixedly mounted on the upper surface of the base plate 1. These components are linearly distributed from right to left along the edge of the base plate 1. A rotating shaft 7 is located on the right side of the adjustment assembly 2 and is rotatably connected to the base plate 1. First support rods 8 are fixedly mounted on both the front and rear sides of the display plate 3, connecting it to the base plate 1. Second support rods 9 are fixedly mounted on both the front and rear sides of the marking plate 4, connecting it to the base plate 1. A conical groove 10 is provided on the side of the marking plate 4 near the round rod 5. A gypsum board 11 is fixedly installed on the inner wall of the conical groove 10. The yarn passes through the buffer assembly 6, the round rod 5, the marking plate 4, the display plate 3, and the adjustment assembly 2 in sequence and is wound around the surface of the rotating shaft 7. The buffer assembly 6 makes the yarn smoothly enter the conical groove 10 of the marking plate 4. The fibers on the surface of the yarn come into contact with the gypsum board 11. The gypsum board 11 marks the fibers on the surface of the yarn. When the marked fibers pass through the display plate 3, the marks on the surface are left on the side of the display plate 3. The operator judges the surface roughness of the yarn by observing the marks on the side of the display plate 3. The adjustment assembly 2 makes the yarn evenly wound around the surface of the rotating shaft 7.

[0021] like Figure 1-2 As shown, there are two round rods 5, which are symmetrically distributed about the center line of the conical groove 10. The side of the display groove corresponding to the conical groove 10 is provided with a through groove 12. The two round rods 5 limit the conical groove 10 to the left and right to prevent the fibers on the surface of the yarn from being missed. The conical groove 10 is the key part for detecting the roughness of the yarn, and the two symmetrical round rods 5 ensure that the yarn can maintain the correct position and angle when entering the conical groove 10.

[0022] like Figure 3 As shown, the buffer assembly 6 includes a pneumatic telescopic rod 13, which is fixedly connected to the base plate 1. A fixed plate 14 is fixedly installed at the end of the pneumatic telescopic rod 13 away from the base plate 1. Side plates 15 are fixedly installed on both sides of the fixed plate 14. A rotating rod 16 is provided between the two side plates 15, and the rotating rod 16 is rotatably connected to both side plates 15. A spring 17 is sleeved on the outer surface of the pneumatic telescopic rod 13. The two ends of the spring 17 are fixedly connected to the surface of the base plate 1 and the bottom surface of the fixed plate 14, respectively. As the core component of the buffer assembly 6, after the yarn comes into contact with the rotating rod 16, the taut yarn applies pressure to the rotating rod 16, thereby causing the pneumatic telescopic rod 13 to contract. The buffer assembly 6 protects the yarn while increasing the tension of the yarn in the equipment.

[0023] like Figure 4 As shown, the adjustment assembly 2 includes a top plate 18, with connecting rods 19 fixedly installed on both sides of the top plate 18. The top plate 18 is fixedly connected to the bottom plate 1 through the connecting rods 19. A sliding groove 20 is provided on the side of the two connecting rods 19 that are close to each other. A lead screw 21 is rotatably installed at the bottom of the inner wall of the sliding groove 20. A movable plate 22 corresponding to the sliding groove 20 is provided below the top plate 18. The movable plate 22 is threadedly connected to the two lead screws 21. A conveying groove 23 is provided through the side of the movable plate 22. When the detected yarn is wound on the surface of the rotating shaft 7, the lead screw 21 rotates, causing the movable plate 22 to drive the yarn in the conveying groove 23 to move up and down, thereby making it evenly wound on the surface of the rotating shaft 7.

[0024] like Figure 1-2 As shown, a limiting plate 24 is fixedly installed on the outer surface of the rotating shaft 7. The limiting plate 24 prevents the yarn on the surface of the rotating shaft 7 from slipping off, and the limiting plate 24 can limit the range of movement of the yarn during the detection process.

[0025] like Figure 1-2 As shown, the conical groove 10 is located between two round rods 5. The precise position of the conical groove 10 between the two round rods 5 provides a clear path for the yarn. When the yarn is detected, it will first pass through the space between the two round rods 5 and then fall accurately into the conical groove 10. When the yarn passes through the conical groove 10, the friction force generated with the groove wall is more uniform and stable, which is conducive to forming clear and accurate marks, thus more realistically reflecting the roughness of the yarn.

[0026] like Figure 4 As shown, buffer plates 25 are fixedly installed on both the upper and lower surfaces of the movable plate 22. When the movable plate 22 moves up and down, the buffer plates 25 can effectively reduce the vibration caused by collision, friction or changes in external force, and protect the movable plate 22 and its connected components from damage. By installing the buffer plates 25, the impact on the movable plate 22 when it comes into direct contact and collision with other hard components is reduced.

[0027] Working principle: After the yarn comes into contact with the rotating rod 16, the taut yarn applies pressure to the rotating rod 16, thereby causing the pneumatic telescopic rod 13 to contract. The buffer assembly 6 and the two round rods 5 cooperate with each other to make the yarn position at the center of the conical groove 10. When the yarn moves in the conical groove 10, the fibers on the surface of the yarn come into contact with the plasterboard 11. The plasterboard 11 marks the fibers on the surface of the yarn. When the marked fibers pass through the display plate 3, the marks on the surface are left on the side of the display plate 3. The operator judges the surface roughness of the yarn by observing the marks on the side of the display plate 3. The screw 21 in the adjusting assembly 2 rotates to make the moving plate 22 drive the yarn in the conveying groove 23 to move up and down, thereby making it evenly wound on the surface of the rotating shaft 7.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
