Finally, one end of the yarn is fixedly connected to the winding positioning frame. Then, the rotary drive assembly and the reel assembly are turned on.

[0022] At the same time, the rotary drive assembly drives the translation guide assembly to move back and forth along the axial direction of the winding positioning frame, thereby driving the yarn to move back and forth along the axial direction of the winding positioning frame, so that the yarn can be evenly wound on the winding positioning frame, and the tensioning assembly can adjust the tension of the yarn being transported, so that the yarn is always in a tensioned state, so that the yarn can be wound on the winding positioning frame in a straight and taut state;

Then, the spectrum detector can be used to perform spectrum detection on the yarn wound on the winding positioning frame.

[0024] When the spectrum detection is completed, the rotary drive assembly and the reel assembly are rotated in opposite directions. At this time, the rotary drive assembly drives the winding positioning frame to rotate in the opposite direction to unwind the yarn, and the reel assembly drives the yarn roll to rotate and rewind, so that the yarn is gradually wound on the yarn roll. At the same time, the reel assembly drives the lifting guide assembly to move up and down, so that the lifting guide assembly drives the yarn to move up and down, so that the yarn is evenly wound on the surface of the yarn roll, and the tensioning assembly can adjust the tension of the yarn being transported, so that the yarn is tightly wound on the yarn roll.

[0025] The present invention has the following beneficial effects:

[0026] 1. In the present invention, the yarn is wound by driving the winding positioning frame through a rotating drive component, and the reeling and winding component drives the yarn roll to rotate and unwind, so that the yarn is gradually wound on the winding positioning frame, and then the spectrum detector is used to perform spectrum detection on the yarn wound into a square. At this time, the yarn is wound and unfolded on the winding positioning frame, thereby increasing the light detection area of ​​the yarn, so that the yarn can fully absorb the light emitted by the scattered spectrum detector, thereby improving the detection accuracy of the spectrum detector on the yarn.

[0027] 2. In the present invention, when the rotating drive assembly drives the winding positioning frame to rotate and wind the yarn, the rotating drive assembly drives the translation guide assembly to move back and forth along the axial direction of the winding positioning frame to drive the yarn to move back and forth along the axial direction of the winding positioning frame, so that the yarn can be evenly wound on the winding positioning frame, and the tensioning assembly can adjust the tension of the yarn in transit to keep the yarn in a tensioned state at all times, so that the yarn can be wound on the winding positioning frame in a straightened and taut state, thereby making the yarn tightly and evenly wound on the winding positioning frame through the cooperation of the translation guide assembly and the tensioning assembly, thereby further improving the uniformity and flatness of the yarn winding, and further improving the detection accuracy of the spectrum detector for the yarn.

[0028] 3. In the present invention, when the spectral detection is completed, the rotary drive assembly and the reel assembly are rotated in the opposite direction. At this time, the rotary drive assembly drives the winding positioning frame to rotate in the opposite direction to unwind the yarn, and the reel assembly drives the yarn roll to rotate and rewind, so that the yarn is gradually wound on the yarn roll, so that the yarn after detection can be automatically recovered without wasting the yarn used for detection; at the same time, the reel assembly drives the lifting guide assembly to move up and down, so that the lifting guide assembly drives the yarn to move up and down, so that the yarn is evenly wound on the surface of the yarn roll, and the tensioning assembly can adjust the tension of the yarn in transit, so that the yarn is tightly wound on the yarn roll, so as to improve the uniformity and tightness of the yarn winding on the yarn roll.

Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0043] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0044] Example 1

[0045] See also Figure 1 、 Figure 2As shown, the present invention is a spectrum detection device, including a frame 1, a spectrum detector 2 is fixedly installed on the upper end of the frame 1, and a positioning mechanism 3 and a winding and unwinding mechanism 4 are installed on the lower end of the frame 1, which are located below the spectrum detector 2; the positioning mechanism 3 includes a rotation drive assembly, a translation guide assembly, a tensioning assembly and a winding positioning frame 33, and the winding positioning frame 33 is arranged directly below the detection head of the spectrum detector 2. The rotation drive assembly can drive the winding positioning frame 33 to rotate, and at the same time, the rotation drive assembly can drive the translation guide assembly to reciprocate along the axial direction of the winding positioning frame 33, and the tensioning assembly can adjust the tension of the object to be detected; the winding and unwinding mechanism 4 includes a winding and unwinding assembly and a lifting guide assembly. When the winding and unwinding assembly rotates, it can drive the lifting guide assembly to move back and forth; the rotation drive assembly and the winding and unwinding assembly can both rotate in both directions;

[0046] Specifically, when the spectrum detection device is used to perform spectrum detection on the yarn 100, the yarn roll 200 is first fixedly mounted on the reel assembly, and the yarn 100 on the yarn roll 200 is sequentially passed through the lifting guide assembly, the tensioning assembly and the translation guide assembly, and finally one end of the yarn 100 is fixedly connected to the winding positioning frame 33, and then the rotary drive assembly and the reel assembly are turned on, the rotary drive assembly drives the winding positioning frame 33 to wind the yarn 100, and the reel assembly is turned on. The yarn reel 200 is driven to rotate and unwind, so that the yarn 100 is gradually wound on the winding positioning frame 33; at the same time, the rotation drive component drives the translation guide component to move back and forth along the axial direction of the winding positioning frame 33, so as to drive the yarn 100 to move back and forth along the axial direction of the winding positioning frame 33, so that the yarn 100 can be evenly wound on the winding positioning frame 33, and the tensioning component can adjust the tension of the yarn 100 being transported, so that the yarn 100 is always in a tensioned state, so that the yarn 100 can be tensioned. The yarn 100 is wound on the winding positioning frame 33 in a straight and taut state; after the yarn 100 is wound on the winding positioning frame 33 with a square and tightly distributed shape, the unwinding and rewinding is stopped, and the winding positioning frame 33 is set horizontally so that the detection head of the spectrum detector 2 is facing the wound yarn 100, and then the spectrum detector 2 can perform spectrum detection on the yarn 100 wound on the winding positioning frame 33; when the spectrum detection is completed, the rotary drive assembly and the unwinding and rewinding assembly are rotated in opposite directions, and the rotary drive assembly drives the unwinding and rewinding assembly to rotate in opposite directions. The dynamic winding positioning frame 33 rotates in the opposite direction to unwind the yarn 100, and the unwinding and rewinding assembly drives the yarn reel 200 to rotate and rewind, so that the yarn 100 is gradually wound on the yarn reel 200. At the same time, the unwinding and rewinding assembly drives the lifting guide assembly to move up and down, so that the lifting guide assembly drives the yarn 100 to move up and down, so that the yarn 100 is evenly wound on the surface of the yarn reel 200, and the tensioning assembly can adjust the tension of the yarn 100 being transported, so that the yarn 100 is tightly wound on the yarn reel 200.

[0047] In this embodiment, the yarn 100 is wound and unfolded on the winding positioning frame 33, thereby increasing the light detection area of ​​the yarn 100, so that the yarn 100 can fully absorb the light emitted by the scattered spectrum detector 2, thereby improving the detection accuracy of the spectrum detector 2 on the yarn 100; and the cooperation of the translation guide component and the tensioning component can make the yarn 100 tightly and evenly wound on the winding positioning frame 33, thereby further improving the detection accuracy of the yarn 100 by improving the uniformity and flatness of the yarn 100 during winding; when the spectrum detection is completed, the rotary drive component and the reel assembly are rotated in reverse, and the rotary drive component drives the winding positioning frame 33 to rotate in reverse to unwind the yarn 100, and the reel assembly drives the yarn reel 200 to rotate and rewind, so that the yarn 100 is rewound on the yarn reel 200, so that the detected yarn 100 can be automatically recovered.

[0048] Example 2

[0049] See also Figures 1-8 As shown, the difference between this embodiment and the above embodiment is that the rotation drive assembly includes a motor base 31, the motor base 31 is fixedly mounted on the lower end of the frame 1, the top of the motor base 31 is fixedly mounted with a winding motor 32, the output end of the winding motor 32 is driven and mounted with a winding drive shaft 318, one end of the winding drive shaft 318 is fixedly connected to one end of the winding positioning frame 33; the translation guide assembly includes a bracket 34, the top of the bracket 34 is rotatably mounted with a translation reciprocating screw rod 35 and a translation guide shaft 32 2. A movable seat 36 is installed on the upper thread drive of the translation reciprocating screw rod 35. One end of the movable seat 36 is slidably plugged into the translation guide shaft 322. A support rod 310 is fixedly installed on the top surface of the movable seat 36, and a guide ring 311 is fixedly installed on the top end of the support rod 310. A driving wheel 319 is installed on the winding drive shaft 318. A driven wheel 321 is fixedly installed on one end of the translation reciprocating screw rod 35. The driving wheel 319 and the driven wheel 321 are connected to each other through a transmission belt 320.

[0050] Among them, the spinning yarn 100 passes through the guide ring 311 before winding. During winding, the winding motor 32 drives the winding drive shaft 318 and the winding positioning frame 33 to rotate, so that the winding positioning frame 33 winds the spinning yarn 100, and at the same time the winding drive shaft 318 drives the driving wheel 319 to rotate, and the driving wheel 319 drives the driven wheel 321 to rotate through the transmission belt 320, thereby driving the translation reciprocating screw rod 35 to rotate, and when the translation reciprocating screw rod 35 rotates, the moving seat 36 is driven by the thread transmission to reciprocate back and forth along the translation reciprocating screw rod 35 and the translation guide shaft 322. At this time, the moving seat 36 drives the support rod 310 and the guide ring 311 to reciprocate back and forth, thereby driving the spinning yarn 100 to reciprocate back and forth through the guide ring 311, so that the spinning yarn 100 is evenly wound on the surface of the winding positioning frame 33.

[0051] Furthermore, the tensioning assembly includes a tensioning seat 38, with guide wheels 39 rotatably mounted on both sides of the top of the tensioning seat 38. A lifting guide groove 313 is provided on the upper end of the tensioning seat 38. A limit guide shaft 315 is fixedly mounted inside the lifting guide groove 313. A lifting slider 314 is also slidably mounted inside the lifting guide groove 313. A tensioning wheel 37 is rotatably mounted on one side of the lifting slider 314. The upper end of the limit guide shaft 315 is movably sheathed with a pressure spring 312 that abuts against the top surface of the lifting slider 314.

[0052] Among them, the spinning yarn 100 passes through the guide wheel 39 and the tensioning wheel 37 in sequence. When the spinning yarn 100 is wound and transported, the spinning yarn 100 is first put into a tensioned state by adjusting the speed difference between the winding and unwinding. At this time, the tensioning wheel 37 moves upward under the tensioning force of the spinning yarn 100, and drives the lifting slider 314 to move upward, so that the lifting slider 314 is in a suspended state in the lifting guide groove 313, and the pressure spring 312 is squeezed and contracted; then the spinning yarn 100 is wound and unwound at a uniform speed, so that the spinning yarn 100 is transported at a uniform speed. When the spinning yarn 100 is transported due to factors such as changes in the winding position during transportation, When the yarn is loose, the lifting slider 314 moves downward under the elastic force of the pressure spring 312, and drives the tensioning wheel 37 to move downward, so that the tensioning wheel 37 and the guide wheel 39 cooperate to tension the yarn 100 again, so that the yarn 100 is always in a tensioned state, which is conducive to winding the yarn 100 tightly on the winding positioning frame 33; accordingly, when the tension of the yarn 100 increases during the transportation process, the yarn 100 drives the tensioning wheel 37 and the lifting slider 314 to move upward through the tension to adjust the tension of the yarn 100 and prevent the yarn 100 from being over-tightened and broken.

[0053] Furthermore, the driving wheel 319 is rotatably mounted on the outer ring of the winding driving shaft 318, the inner ring of the driving wheel 319 is provided with a circumferentially distributed ratchet 323, and a positioning sleeve 324 is fixedly mounted on the winding driving shaft 318. The outer ring of the positioning sleeve 324 is rotatably mounted with a ratchet 325 that can be unidirectionally engaged with the ratchet 323; wherein, when the winding driving shaft 318 rotates to drive the winding positioning frame 33 to reel in the spun yarn 100, the winding driving shaft 318 drives the driving wheel 319 to rotate simultaneously through the engagement of the ratchet 325 and the ratchet 323. When the winding drive shaft 318 rotates in the opposite direction to drive the winding positioning frame 33 to unwind the yarn 100, the pawl 325 and the ratchet 323 are no longer engaged, so that the winding drive shaft 318 no longer drives the driving wheel 1319 and the translation reciprocating screw rod 35 to rotate, thereby keeping the guide ring 311 stationary, preventing the reciprocating movement of the guide ring 311 from affecting the tension of the yarn 100, and reducing the difficulty of adjusting the tensioning assembly.

[0054] Furthermore, a positioning hole 316 is provided at one end of the winding positioning frame 33, and a hand-tightening bolt 317 extending into the positioning hole 316 is rotatably installed on the side of the end of the winding positioning frame 33. Before winding the yarn 100, one end of the yarn 100 is inserted into the positioning hole 316, and then the hand-tightening bolt 317 is tightened inward, so that the end of the yarn 100 can be pressed and fixed, thereby making the connection and fixation between the yarn 100 and the winding positioning frame 33 more convenient and quick.

[0055] Example 3

[0056] See also Figure 1-Figure 7 、 Figure 9 As shown, the difference between this embodiment and the above embodiment is that the rewinding and unwinding assembly includes a motor box 41 fixedly mounted on the lower end of the frame 1, a rewinding and unwinding motor 410 is fixedly mounted inside the motor box 41, an output end of the rewinding and unwinding motor 410 is transmission-mounted with a rewinding and unwinding drive shaft 411, a top end of the rewinding and unwinding drive shaft 411 is fixedly mounted with a threaded sleeve 48 extending above the motor box 41, a bottom end of the threaded sleeve 48 is fixedly mounted with a chassis 42, a threaded rod 49 is rotatably mounted on the upper end of the threaded sleeve 48, and a pressure plate 43 is fixedly mounted on the top end of the threaded rod 49;

[0057] The lifting guide assembly includes a lifting reciprocating screw rod 44, a lifting guide shaft 45, and a second driving wheel 412. The lifting reciprocating screw rod 44 and the lifting guide shaft 45 are arranged in parallel and are both rotatably mounted on the top surface of the motor box 41. A lifting seat 46 is threadedly mounted on the lifting reciprocating screw rod 44. One end of the lifting seat 46 is slidably connected to the lifting guide shaft 45, and a limiting hole 47 is defined in the lifting seat 46. The bottom end of the lifting reciprocating screw rod 44 extends into the interior of the motor box 41 and is fixedly mounted with a second driven wheel 414. The second driving wheel 412 is mounted on the rewinding and unwinding drive shaft 411. The second driving wheel 412 and the second driven wheel 414 are connected by a second transmission belt 413.

[0058] Before testing, the yarn roll 200 is inserted into the outer ring of the threaded sleeve 48, and then the threaded rod 49 is inserted into the top of the threaded sleeve 48, and the threaded rod 49 and the threaded sleeve 48 are rotated relative to each other, so that the threaded rod 49 is gradually screwed into the interior of the threaded sleeve 48, and at the same time, the threaded rod 49 drives the pressing plate 43 downward, so that the pressing plate 43 cooperates with the chassis 42 to clamp and fix the yarn roll 200, and at the same time, one end of the spinning yarn 100 is passed through the limiting hole 47, and then the rewinding and unwinding motor 410 drives the rewinding and unwinding drive shaft 411 and the threaded sleeve 48 to rotate, thereby driving the yarn roll 200 to rotate and unwind;

[0059] Furthermore, a second driving wheel 412 is rotatably mounted on the reel drive shaft 411. The inner ring of the second driving wheel 412 is fixedly mounted with second ratchet teeth 415 distributed in a circumferential manner. A second positioning sleeve 416 is fixedly mounted on the reel drive shaft 411 and is located on the inner ring of the second driving wheel 412. The outer ring of the second positioning sleeve 416 is rotatably mounted with a second ratchet pawl 417 that can unidirectionally engage with the second ratchet teeth 415.

[0060] When the unwinding and rewinding drive shaft 411 drives the threaded sleeve 48 and the yarn roll 200 to rotate and unwind, the second ratchet 415 and the second pawl 417 are not engaged, so that the unwinding and rewinding drive shaft 411 will not drive the lifting guide assembly to work, thereby preventing the lifting guide assembly from driving the spinning 100 to move up and down and affecting the tension of the spinning 100; and when the unwinding and rewinding drive shaft 411 drives the threaded sleeve 48 and the yarn roll 200 to rotate in the opposite direction to rewind the spinning 100, the second ratchet 415 and the second pawl 417 are engaged, so that When the rewinding and unwinding drive shaft 411 rotates, it drives the driving wheel 2 412 to rotate synchronously through the ratchet 2 415 and the pawl 2 417. At this time, the driving wheel 2 412 drives the driven wheel 2 414 to rotate synchronously through the transmission belt 2 413, thereby driving the lifting and reciprocating screw rod 44 to rotate. When the lifting and reciprocating screw rod 44 rotates, it drives the lifting seat 46 to move back and forth through the threaded transmission. When the lifting seat 46 moves back and forth, it drives the spinning yarn 100 to move back and forth through the limiting hole 47, so that the spinning yarn 100 is evenly wound on the yarn roll 200.

[0061] Example 4

[0062] This embodiment discloses a spinning detection method, and the specific steps are as follows:

[0063] First, the yarn roll 200 is fixedly installed on the reel assembly, and the yarn 100 on the yarn roll 200 is sequentially passed through the lifting guide assembly, the tensioning assembly and the translation guide assembly. Finally, one end of the yarn 100 is fixedly connected to the winding positioning frame 33. Then, the rotary drive assembly and the reel assembly are turned on. The rotary drive assembly drives the winding positioning frame 33 to wind the yarn 100, and the reel assembly drives the yarn roll 200 to rotate and unwind, so that the yarn 100 is gradually wound on the winding positioning frame 33.

[0064] At the same time, the rotary drive assembly drives the translation guide assembly to reciprocate along the axial direction of the winding positioning frame 33, thereby driving the yarn 100 to reciprocate along the axial direction of the winding positioning frame 33, so that the yarn 100 can be evenly wound on the winding positioning frame 33, and the tensioning assembly can adjust the tension of the yarn 100 being transported, so that the yarn 100 is always in a tensioned state, so that the yarn 100 can be wound on the winding positioning frame 33 in a straight and taut state;

[0065] After the yarn 100 is tightly distributed in a square shape wound on the winding positioning frame 33, the winding and unwinding is stopped, and the winding positioning frame 33 is set horizontally so that the detection head of the spectrum detector 2 is facing the wound yarn 100. Then, the spectrum detector 2 can perform spectrum detection on the yarn 100 wound on the winding positioning frame 33;

[0066] When the spectral detection is completed, the rotary drive assembly and the unwinding assembly are rotated in the opposite direction. At this time, the rotary drive assembly drives the winding positioning frame 33 to rotate in the opposite direction to unwind the yarn 100, and the unwinding assembly drives the yarn roll 200 to rotate and rewind, so that the yarn 100 is gradually wound on the yarn roll 200. At the same time, the unwinding assembly drives the lifting guide assembly to move back and forth, so that the lifting guide assembly drives the yarn 100 to move up and down, so that the yarn 100 is evenly wound on the surface of the yarn roll 200, and the tensioning assembly can adjust the tension of the yarn 100 in transport, so that the yarn 100 is tightly wound on the yarn roll 200.
