Description

Technical Field

[0001] The present invention relates to the technical field of yarn detection equipment, and in particular to an online detection mechanism for concentrated spun yarn quality. Background Art

[0002] Compact spinning, also known as "condensed spinning," is a ring spinning method that produces a denser yarn structure. Its core technology involves installing a condensing device at the output end of the front rollers. This allows the sliver to be condensed before being twisted. This separates drafting and condensing, avoiding friction distribution in the drafting zone due to the condensing effect. The sliver width decreases after condensing after being drafted. After condensed yarn production is completed, yarns from both the same and different batches must be tested to ensure quality.

[0003] When testing the quality of spinning yarns, commonly used spinning yarn testing equipment cannot simultaneously test a large number of spinning yarns of different batches and specifications, and can only test a single aspect of the spinning yarn. When in use, it is impossible to perform multi-faceted testing on a large number of spinning yarns of different models at the same time, resulting in low spinning yarn testing efficiency. At the same time, common spinning yarn testing methods are to divide the spinning yarns of the same batch into multiple parts and perform different aspect testing on them respectively to prevent the same part of the spinning yarn from being affected by the testing process and results after being tested in one aspect and then in another aspect. When in use, the testing in different directions cannot cooperate with each other to make the multi-faceted testing results of the spinning yarn more accurate. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The detection device of the present invention can be folded and stored as a whole, which is convenient for the staff to store and place the detection device. At the same time, several conveying cylinders used for spinning line detection can be installed inside the detection device at the same time, and a large number of spinning lines of different specifications can be detected and used at the same time, thereby improving the detection efficiency of the spinning line. When the spinning line is conveyed, the edges of the two ends of the first conveying hole rub the spinning line, and the electrostatic generator inside the conveying cylinder can release static electricity on the surface of the spinning line. After the friction, the surface of the spinning line will have hooks or fibers will move to the surface, resulting in a large amount of fluff on the surface of the fabric. When in use, it can prevent the spinning line from friction and The toughness and strength are tested. When the static electricity released by the electrostatic generator comes into contact with the spinning thread after friction, the plush on the surface of the spinning thread will stand up. When in use, the anti-static effect of the spinning thread can be tested. When the spinning thread is transported to the side of the scanner, the scanner can scan the spinning thread. When in use, the anti-friction effect of the spinning thread can be tested according to the number and degree of plush on the surface of the spinning thread. The heating plate can heat the spinning thread, which is convenient for testing the thermal strength of the spinning thread. At the same time, when the heating plate tests the spinning thread, when the thermal intensity of the spinning thread is low, the plush on the surface of the frictional spinning thread will curl up and deform.

[0018] 2. In the present invention, when the conveying drum detects the spinning line, the heat absorbing plate located on the outer wall of the conveying drum can absorb the light irradiated on the surface of the conveying drum from the outside. The heat absorbing plate is a solar panel. When in use, it uses the photoelectric effect to convert solar energy into electrical energy, and the converted electrical energy is electrically connected to the electrostatic generator, scanner, heating plate and several electric rotating shafts, so that the detection equipment itself converts electrical energy through solar energy when in use, and consumes the converted electrical energy when detecting the spinning line. When in use, the detection equipment can be used for electrical energy conversion and can perform multi-faceted detection on a large number of spinning lines at the same time.

[0019] 3. In the present invention, after the spinning line inspection is completed, the staff can disassemble the conveying cylinder and place the disassembled conveying cylinder inside the placement groove on the top of the placement plate, and rotate the rotating plate at the same time to make the rotating plate rotate to the top of the placement plate. When in use, the placement plate and the rotating plate can clamp and protect the conveying cylinder, and at the same time push the placement plate and the rotating plate until the rotating plate and the support plate abut against each other, and the telescopic rod pulls the moving plate so that the moving plate cooperates with the fixed plate and the support plate to clamp the placement plate and the rotating plate. When in use, the placement plate, the rotating plate and the moving plate are retracted toward the fixed plate, and the fixed plate is folded at the same time. It is convenient for the staff to store and accommodate the testing equipment. The conveying drum can not only transport the spinning line, but also provide good protection for the spinning line during transportation. The conveying drum can also be used to perform tension testing, heat resistance testing, friction strength testing, and anti-static testing on the spinning line at the same time, making the detection of the spinning line more comprehensive. At the same time, when the scanner scans the fluff on the surface of the spinning line, it can also scan the diameter of the spinning line to prevent the spinning line from having different diameters at different positions. At the same time, it can also prevent the spinning line from being damaged or about to break on the surface during the wear resistance test of the spinning line due to the poor wear resistance of the spinning line.

[0020] 4. In the present invention, the staff can adjust the distance between the fixed plate and the movable plate according to the usage, and install and place the conveying cylinder according to the number of spinning threads to be detected. The conveying cylinder is composed of two arc-shaped plates rotatably connected to each other. When the spinning thread is installed, the conveying cylinder can be opened, and the spinning thread can be limited and supported by the baffle and the limit plate. At the same time, the baffle and the limit plate can divide the interior of the conveying cylinder into several areas, so that several areas can be detected in different directions respectively. The beneficial aspects cooperate with each other, such as releasing static electricity on the spinning thread, so that the plush on the surface of the spinning thread after friction stands up, which is convenient for the scanner to scan the spinning thread and the plush on its surface, and it is convenient for the heating plate to heat and detect the plush on the surface of the spinning thread, but the baffle and the limit plate can isolate the various areas from each other to prevent the heat dissipated by the heating plate from having a greater impact on the magnificent detection plate.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] Reference Figure 1-8, an online detection mechanism for the quality of concentrated spinning yarn, comprising a fixed plate 1, a support plate 2 is rotatably installed on the top of the fixed plate 1, telescopic rods 24 are installed at both ends of one side of the support plate 2, a placing plate 3 is slidably installed on the top of the telescopic rod 24 near the end of the fixed plate 1, the placing plate 3 is rotatably installed on the side away from the fixed plate 1 with a rotating plate 4, and a movable plate 5 is installed on the end of the telescopic rod 24 away from the fixed plate 1, and a placing groove 8 is provided on the top of the placing plate 3 and the rotating plate 4 in the length direction, and a plurality of conveying cylinders 6 are obliquely installed on the side of the top of the support plate 2 near the movable plate 5. The conveying cylinder 6 is composed of two arc-shaped plates rotatably connected to each other, and heat absorbing plates 7 are installed on the outer walls of the arc-shaped plates.

[0033] As a technical optimization solution of the present invention, a plurality of first limiting grooves 16 are provided at the corner position of one side of the top of the support plate 2 close to the movable plate 5, and a plurality of second limiting grooves 19 are provided on the inner wall of the placement groove 8 at the top of the rotating plate 4 away from the fixed plate 1. The bottom end of the conveying cylinder 6 is located inside the second limiting groove 19, and the top end of the conveying cylinder 6 is located inside the first limiting groove 16. A first conveying hole 20 is provided on the inner wall of the second limiting groove 19 away from the fixed plate 1; when in use, the first limiting groove 16 and the second limiting groove 19 respectively support and limit the position of the two ends of the conveying cylinder 6.

[0034] As a technical optimization solution of the present invention, a plurality of baffles 28 are installed on the inner wall of the conveying cylinder 6, and a limit plate 29 is rotatably installed on the side of the baffle 28. A limit hole 30 is provided at one end of the side of the limit plate 29 and the baffle 28, wherein a guide rod 37 is installed on the top of the opposite surface of two adjacent baffles 28, and a movable sleeve 38 is slidably installed on the outer wall of both ends of the guide rod 37, and a connecting rod 40 is rotatably installed on the bottom end of the movable sleeve 38, and a spring 39 is installed on the outer wall of the guide rod 37 between the baffle 28 and the movable sleeve 38; when the spinning line is transported through the inside of the conveying cylinder 6, the tension detection plate 34 presses the spinning line downward by the elasticity of the spring 39, so that the spinning line between the two baffles 28 at both ends of the tension detection plate 34 is curved due to the extrusion of the tension detection plate 34. When the spinning line is too loose during transportation, the spinning line below the tension detection plate 34 is positioned The mutual friction between the two ends of the device and the limiting holes 30 on the baffle 28 will increase, resulting in a slower delivery of the spinning line. The staff can pull the spinning line by speeding up the rotation speed of the winding wheel 13, so that the deformation of the spinning line under the tension detection plate 34 due to the elastic extrusion of the spring 39 is reduced, and at the same time, the friction between the spinning line and the limiting hole 30 is reduced. The looser the spinning line is during transportation, the smaller the squeezing force of the spinning line on the tension detection plate 34 is, and the closer the spinning line is to a taut state during transportation, the greater the squeezing force on the tension detection plate 34 is, and the tension detection plate 34 can monitor the squeezing force of the spinning line, and the tension detection plate 34 is electrically connected to an external display. The staff can understand the tension of the spinning line through the display results on the display, and it is convenient for the staff to adjust the tightness of the spinning line during transportation by rotating the winding wheel 13.

[0035] As a technical optimization solution of the present invention, a tension detection plate 34 is installed inside the conveying cylinder 6 below the guide rod 37, and the two connecting rods 40 are rotatably connected to the two ends of the tension detection plate 34 at one end away from the movable sleeve 38. The bottom of the tension detection plate 34 is provided with an arc groove 41 in the length direction; the spinning line is located inside the arc groove 41 during conveyance, and the arc groove 41 can play a better guiding and position limiting role for the conveyed spinning line.

[0036] As a technical optimization solution of the present invention, a heating plate 31 is installed on the inner wall of the conveying cylinder 6 between the two adjacent baffles 28, and the heating plate 31 is located on the side of the guide rod 37 close to the support plate 2. A scanner 32 is installed on the inner wall of the conveying cylinder 6 on the side of the guide rod 37 close to the movable plate 5. An electrostatic generator 33 is installed on the inner wall of the conveying cylinder 6 on the side of the scanner 32 close to the movable plate 5. The heating plate 31 can heat the conveyed spinning thread when in use, and can detect the heat resistance of the spinning thread when in use.

[0037] As a technical optimization solution of the present invention, a second card slot 35 is provided at the top of one of the curved plates constituting the conveying cylinder 6, a second card block 36 is installed on the side of the top of the other curved plate, a fixed slot 9 is provided at the top of the placement plate 3 in the length direction, and a plurality of second conveying holes 27 matching the first conveying holes 20 are provided on the inner wall of the fixed slot 9 close to the fixed plate 1; when in use, the conveying cylinder 6 is composed of two curved plates, and the bottom ends of the two curved plates are rotatably connected to each other. When the staff needs to install and place the conveyed spinning line, the staff can open the curved plate. When the spinning line is conveyed and tested, the two curved plates abut against each other, so that the two curved plates form a cylindrical conveying cylinder 6.

[0038] As a technical optimization solution of the present invention, an inner cavity 14 is provided inside the support plate 2, and a plurality of feed holes 15 are opened at the inner top of the inner cavity 14. The top of the feed hole 15 is located on the side of the first limiting groove 16, and a through hole 25 is opened on the side of the inner bottom of the inner cavity 14 close to the movable plate 5; when the spinning line inspection is completed, the inner cavity 14 can be entered through the feed hole 15, which is convenient for the staff to collect the inspected spinning line.

[0039] As a technical optimization solution of the present invention, a groove 11 is provided on the side of the support plate 2 away from the movable plate 5, and the bottom end of the through hole 25 is communicated with the groove 11. Several electric rotating shafts 12 are rotatably installed on the inner wall of the groove 11, and a winding wheel 13 is installed on the outer wall of the electric rotating shaft 12. A first card groove 22 is provided on the top of the fixed plate 1 close to the end of the support plate 2, and a first card block 23 is installed on the side of the bottom end of the support plate 2 away from the movable plate 5; when in use, each conveying drum 6 corresponds to each winding wheel 13, and the winding wheel 13 winds up the spinning line after inspection.

[0040] As a technical optimization solution of the present invention, guide grooves 26 are provided at both ends of the bottom of the placement plate 3 and the rotating plate 4. The end of the telescopic rod 24 close to the fixed plate 1 is slidably installed in the guide groove 26 at the bottom of the placement plate 3, and the end of the telescopic rod 24 close to the movable plate 5 is movably installed in the guide groove 26 at the bottom of the rotating plate 4; when in use, the telescopic rod 24 can adjust the distance between the fixed plate 1 and the movable plate 5, making it convenient for the staff to fold and store the detection equipment at any time.

[0041] As a technical optimization solution of the present invention, connecting grooves 17 are provided on the opposite surfaces of the placement plate 3 and the rotating plate 4, and a connecting plate 18 is installed between the placement plate 3 and the rotating plate 4. The two sides of the connecting plate 18 are respectively rotatably installed on the inner walls of the two connecting grooves 17, and support legs 10 are installed at both ends of the bottom of the fixed plate 1 and the movable plate 5. Universal wheels 21 are rotatably installed on the side surfaces of the bottom ends of the support legs 10 located on the movable plate 5; when the spinning line inspection is completed, the staff can place the conveying cylinder 6 inside the placement groove 8, and fold the rotating plate 4 so that the tops of the placement plate 3 and the rotating plate 4 abut against each other, and clamp and protect the conveying cylinder 6.

[0042] When using the present invention, a worker rotates the support plate 2 so that it is mounted vertically on top of the fixed plate 1. Simultaneously, the worker pushes the movable plate 5 via the telescopic rod 24 to move it, adjusting the distance between the fixed plate 1 and the movable plate 5 according to the usage. The worker rotates the rotating plate 4 so that the placement plate 3 and the rotating plate 4 lie flat on top of the telescopic rod 24, with the end of the rotating plate 4 away from the placement plate 3 abutting against the movable plate 5. The worker installs and positions the conveying drum 6 based on the number of spinning threads detected. During use, the worker places the conveying drum 6 above the placement plate 3, with the top end of the conveying drum 6 located within the first limiting groove 16 at the top of the support plate 2, and the bottom end of the conveying drum 6 located within the second limiting groove 19 on the inner wall of the placement groove 8 at the top of the rotating plate 4.

[0043] The conveying drum 6 is composed of two curved plates, and the bottom ends of the two curved plates are rotatably connected to each other. When in use, the staff opens one of the curved plates. The staff places one end of the spinning line to be tested inside the fixed groove 9 on the top of the movable plate 5, and passes one end of the spinning line through the second conveying hole 27 and the first conveying hole 20 to the inside of the second limiting groove 19, and one end of the spinning line passes through several baffles 28 inside the conveying drum 6 and the limiting hole 30 on the limiting plate 29. After the spinning line passes through the conveying drum 6, one end of the spinning line passes through the feed hole 15, the inner cavity 14 and the through hole 25, and is wound on the winding wheel 13. When in use, several winding wheels 13 correspond to several conveying drums 6 respectively, so that the spinning line tested inside a single conveying drum 6 is wound on the corresponding winding wheel 13, which is convenient for the staff to mark the tested spinning line and to take away the unqualified spinning line.

[0044] When the staff has placed the spinning line to be tested, the staff rotates the limit plate 29 so that the limit plate 29 rotates on the side of the baffle 28. The baffle 28 and the limit holes 30 on the limit plate 29 on its side are staggered with each other, but the limit holes 30 on the baffle 28 and the limit plate 29 are still overlapped near the center line of the conveying cylinder 6. The position of the limit holes 30 on the baffle 28 and the limit plate 29 at the center line of the conveying cylinder 6 can limit the position of the spinning line transported inside the conveying cylinder 6, and can also support the spinning line, so that the spinning line is more stable when transported inside the conveying cylinder 6, and prevent the spinning line from shaking during transportation, resulting in the electrostatic generator 33, the scanner 32 and the tension detection plate 34 being unable to accurately detect the spinning line.

[0045] When in use, the electric shaft 12 drives the winding wheel 13 to rotate, and the electric shaft 12 pulls the transported spinning thread to be wound, while the external unwinding wheel feeds the spinning thread into the fixed groove 9. When the yarn is transported and tested, the first transport hole 20 and the feed hole 15 limit the position of the yarn at both ends of the transport cylinder 6, and prevent the yarn near the first transport hole 20 and the feed hole 15 from pulling the transport cylinder 6 to cause displacement during use. At the same time, the edge positions at both ends of the first transport hole 20 rub the yarn during use. After the yarn after friction enters the interior of the transport cylinder 6, the electrostatic generator 33 located inside the transport cylinder 6 can release static electricity on the surface of the yarn. After friction, the surface of the yarn will have hooks or fibers will migrate to the surface, resulting in a large amount of fluff on the surface of the fabric. When in use, the anti-friction and toughness strength of the yarn can be tested. When the static electricity released by the electrostatic generator 33 comes into contact with the yarn after friction, the fluff on the surface of the yarn will stand up. When in use, the anti-static property of the yarn can be tested. When the yarn is transported to the side of the scanner 32, the scanner 32 can scan the yarn. When in use, the anti-friction effect of the yarn can be tested according to the number and degree of fluff on the surface of the yarn.

[0046] When in use, the bottom end of the tension detection plate 34 located inside the conveying tube 6 abuts against the spinning line, and the conveyed spinning line is located inside the arc groove 41 at the bottom end of the tension detection plate 34. When in use, the spring 39 can push the movable sleeve 38 and the connecting rod 40 through its own elasticity, so that the tension detection plate 34 squeezes the conveyed spinning line, so that the spinning line is always in a taut state during transportation, which is convenient for toughness testing of the spinning line. The spinning line between the two baffles 28 at both ends of the tension detection plate 34 is deformed into an arc shape due to the squeezing of the tension detection plate 34. When the spinning line is too loose during transportation, the tension detection plate 34 will push the spinning line to move toward the inner wall of the conveying cylinder 6, so that the spinning line is always in a taut state, and the mutual friction between the two ends of the spinning line below the tension detection plate 34 and the limiting holes 30 on the baffle 28 will increase, resulting in a slower spinning line transportation. The staff will pull the spinning line in transportation by increasing the speed of the winding wheel 13, so that the spinning line below the tension detection plate 34 will be deformed due to the elastic squeezing of the spring 39. The arc angle becomes smaller, and at the same time, the friction between the spinning line and the limiting hole 30 is reduced. When in use, the tension detection plate 34 detects the tension of the spinning line by squeezing the squeezed spinning line, and at the same time, it is convenient for the staff to adjust the tightness of the spinning line during transportation. When in use, the spring 39 is squeezed by force. The shorter the distance between the two ends of the spring 39, the greater the force of the spinning line pushing the tension detection plate 34, and the greater the pulling force at the two ends of the spinning line located below the tension detection plate 34. The tension detection plate 34 can detect the force situation, and the staff can detect the tension of the spinning line by the force level of the tension detection plate 34. When the spinning line is transported to the side of the heating plate 31, the heating plate 31 can heat the spinning line, which is convenient for detecting the thermal intensity of the spinning line. At the same time, when the heating plate 31 detects the spinning line, when the thermal intensity of the spinning line is low, the velvet on the surface of the rubbed spinning line will curl up and deform. When the spinning thread in transportation is heated during the tensioning and conveying process, because the fibers in the spinning thread are relatively complete and are in the pulling and conveying process, the spinning thread will not show any other obvious deformation except slight stretching when heated. It is inconvenient for the staff to observe the thermal strength of the spinning thread during use. The snagged plush that appears on the surface of the spinning thread after friction will deform and curl after being heated, and the staff can detect and understand the thermal strength of the spinning thread based on the degree of curling of the surface plush.

[0047] When the conveying drum 6 detects the spinning line, the heat absorbing plate 7 located on the outer wall of the conveying drum 6 can absorb the light from the outside irradiating the surface of the conveying drum 6. The heat absorbing plate 7 is a solar panel. When in use, it uses the photoelectric effect to convert solar energy into electrical energy, and the converted electrical energy is electrically connected to the electrostatic generator 33, the scanner 32, the heating plate 31 and several electric rotating shafts 12, so that the detection equipment itself converts electrical energy through solar energy when in use, and consumes the converted electrical energy when detecting the spinning line. When in use, the detection equipment can be used for electrical energy conversion and can also perform multi-faceted detection on a large number of spinning lines at the same time.

[0048] When the yarn inspection is completed, the staff can disassemble the conveying cylinder 6 and place the disassembled conveying cylinder 6 inside the placement groove 8 on the top of the placement plate 3. The staff rotates the support plate 2 to make the support plate 2 rotate to the top of the fixed plate 1, and at the same time rotates the rotating plate 4 to make the rotating plate 4 rotate to the top of the placement plate 3. When in use, the placement plate 3 and the rotating plate 4 can clamp and protect the conveying cylinder 6, and at the same time push the placement plate 3 and the rotating plate 4 until the rotating plate 4 and the support plate 2 abut against each other, and the telescopic rod 24 pulls the movable plate 5 so that the movable plate 5 cooperates with the fixed plate 1 and the support plate 2 to clamp the placement plate 3 and the rotating plate 4. When in use, the placement plate 3, the rotating plate 4 and the movable plate 5 are retracted toward the fixed plate 1, and the fixed plate 1 is folded at the same time, which is convenient for the staff to store the detection equipment.
