DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-Figure 8A color fastness testing device comprises a testing cabinet 1, wherein a cleaning chamber 11, a drying chamber 12 and a testing chamber 13 which are interconnected are sequentially arranged in the testing cabinet 1, a discharge port 111 is opened at the top of the cleaning chamber 11, a cleaning barrel 2, a conveying assembly 4, a clamping assembly 5 and a friction assembly 6 are also arranged in the testing cabinet 1, the cleaning barrel 2 is located in the cleaning chamber 11, the conveying assembly 4 is located above the cleaning barrel 2, the clamping assembly 5 comprises a rotating arm 51, a telescopic cylinder 53 and a clamping plate 56, the rotating arm 51 cooperates with the conveying assembly 4, the telescopic cylinder 53 is installed on the rotating arm 51, when cleaning the sample, the sample is placed in the clamping plate 56 for fixing, the conveying assembly 4 drives the rotating arm 51 to move, and the clamping plate 56 is placed in the cleaning barrel 2;

[0033] The friction assembly 6 includes a movable ring 61, a pressure plate 63, a friction plate 64 and a fixed plate 65. The movable ring 61 is slidably set on the output shaft of the telescopic cylinder 53 and is located on one side of the clamping plate 56. A supporting spring 62 is fixedly connected between the movable ring 61 and the output shaft of the telescopic cylinder 53. The supporting spring 62 pushes the movable ring 61 to approach the clamping plate 56. The pressure plate 63 is connected to both sides of the movable ring 61. When the movable ring 61 approaches the clamping plate 56, the pressure plate 63 drives the clamping plate 56 to clamp and fix the sample. Clamping cylinders 612 are respectively set on both sides of the movable ring 61. The friction plate 64 and the fixed plate 65 are respectively connected to the clamping cylinder 612. The inner sides of the friction plate 64 and the fixed plate 65 are provided with a plurality of protrusions that generate friction. After the sample is placed in the cleaning barrel 2, the two clamping cylinders 612 synchronously drive the friction plate 64 and the fixed plate 65 to approach the sample.

[0034] When in use, firstly, water for cleaning samples is poured into the cleaning bucket 2, and cleaning agent is added into the cleaning bucket 2 through the discharge port 111. At this time, the rotating arm 51 is located on the side of the cleaning bucket 2 away from the drying chamber 12, and the clamping plate 56 thereon is vertically upward. Before placing the sample, the telescopic cylinder 53 extends the output shaft to extend the clamping plate 56 out of the discharge port 111 to place the sample. When the clamping plate 56 does not start to clamp the sample, the supporting spring 62 pushes the movable ring 61 close to one side of the clamping plate 56, and the movable ring 61 pushes the pressing plate 63 to close the clamping plate 56. When placing the sample, the inspector manually pushes the movable ring downward. 61, the movable ring 61 pulls the pressure plate 63 away from the clamping plate 56, opens the closed clamping plate 56, and compresses the support spring 62, placing the sample into the opened clamping plate 56, then releases the movable ring 61, the support spring 62 recovers its deformation and pushes the movable ring 61 close to the clamping plate 56 again, and closes the opened clamping plate 56 through the pressure plate 63, so that the clamping plate 56 fixes and clamps the sample, then the telescopic cylinder 53 retracts the clamping plate 56 into the cleaning chamber 11, and the conveying assembly 4 drives the rotating arm 51 to move a certain distance toward the drying chamber 12, and the rotating arm 51 drives the telescopic cylinder 53 to flip clockwise during the movement. One hundred and eighty degrees, the clamping plate 56 is vertically downwardly aligned with the cleaning barrel 2, and the telescopic cylinder 53 inserts the clamping plate 56 and the sample thereon into the cleaning barrel 2 to start cleaning the sample. During the cleaning process, the clamping cylinder 612 pushes the friction plate 64 and the fixed plate 65 toward the sample until the friction plate 64 and the fixed plate 65 collide with the sample, and then the friction assembly 6 cooperates with the fixed plate 65 through the swing of the friction plate 64, and rubs the sample through the convex points on both, thereby simulating the effect of scrubbing in water. After the cleaning of the sample is completed, the friction assembly 6 stops working, and the telescopic cylinder 53 retracts the clamping plate 56 and the sample thereon, and then the conveying assembly Component 4 drives the rotating arm 51 to continue moving toward the drying chamber 12. During this process, the rotating arm 51 will flip counterclockwise by 90 degrees, so that the clamping plate 56 carries the sample toward the drying chamber 12 and remains horizontal. After the sample enters the drying chamber 12, the conveying component 4 stops working for a period of time, and the clamping cylinder 612 drives the friction plate 64 and the fixed plate 65 away from the sample to facilitate the drying of the sample. The sample begins to dry in the drying chamber 12. After the sample is dried, the conveying motor 41 is started again to send the dried sample to the detection chamber 13 for detection. After the detection is completed, the conveying component 4 drives the rotating arm 51 back to the cleaning chamber 11.

[0035] The difference from the above embodiment is that the conveying assembly 4 includes a conveying motor 41, a slide 44 and a driving member 45. The conveying motor 41 is fixedly connected to the outside of the detection cabinet 1, and a threaded rod 42 is coaxially fixedly connected to its output shaft. The threaded rod 42 penetrates the outer wall of the cleaning chamber 11 and is rotatably connected to the inner wall of the detection chamber 13. A guide rod 43 is fixedly installed between the inner wall of one side of the cleaning chamber 11 and the inner wall of one side of the detection chamber 13. The guide rod 43 is flush with the threaded rod 42. A slide 44 is fixedly connected between the cleaning chamber 11 and the detection chamber 13. The slide 44 is located between the threaded rod 42 and the cleaning barrel 2. One side of the driving member 45 is transferred to the threaded rod 42 through a thread, and the other side of the slide 44 is installed on the guide rod 43.

[0036] Among them, when the rotating arm 51 is transported toward the detection chamber 13, the transport motor 41 drives the threaded rod 42 to rotate in the opposite direction, so that the driving member 45 drives the rotating arm 51 to move toward the detection chamber 13 under the guidance of the guide rod 43; when the rotating arm 51 is retracted from the detection chamber 13 to the cleaning chamber 11, the transport motor 41 drives the threaded rod 42 to rotate in the forward direction, so that the driving member 45 drives the rotating arm 51 to move toward the cleaning chamber 11 under the guidance of the guide rod 43.

[0037] The difference from the above embodiment lies in that a lower rack 441 is fixedly installed on the lower side of one end of the slide 44 located in the cleaning chamber 11, and the lower rack 441 is far away from the drying chamber 12; an upper rack 442 is fixedly installed on the upper side of one end of the slide 44 located in the cleaning chamber 11, and the upper rack 442 is located on one side of the lower rack 441 and close to the drying chamber 12; a convex strip 443 is also fixedly connected to the upper and lower sides of the slide 44, and the convex strip 443 is located on the side of the upper rack 442 close to the drying chamber 12, and the convex strip 443 extends on the slide 44 to the detection chamber 13.

[0038] The difference from the above embodiment is that the rotating arm 51 is rotatably mounted on the driving member 45 through the driving shaft 511, the driving shaft 511 penetrates the driving member 45 and extends out from the slide 44, and the driving shaft 511 is symmetrically provided with limiting grooves 5111, the limiting grooves 5111 correspond to the convex strips 443, and the driving shaft 511 is also coaxially fixedly connected with a reversing gear 52, and the reversing gear 52 can respectively engage with the lower rack 441 and the upper rack 442, and the telescopic cylinder 53 is fixedly mounted on the rotating arm 51, and the output shaft of the telescopic cylinder 53 penetrates the rotating arm 51 and extends out therefrom, and a fixed splint 54 is fixedly connected to the protruding end of the output shaft of the telescopic cylinder 53, and a plurality of pressure springs 55 are fixedly connected between the fixed splint 54 and the clamping plate 56.

[0039] Among them, during the initial loading, the reversing gear 52 is meshed with one end of the lower rack 441. When the conveying assembly 4 drives the rotating arm 51 to move on the slide 44 toward the drying chamber 12, the reversing gear 52 rotates clockwise with the cooperation of the lower rack 441. When the reversing gear 52 drives the rotating arm 51 to flip 180 degrees, the reversing gear 52 comes to the other end of the lower rack 441, and one side of it begins to mesh with one end of the upper rack 442. As the rotating arm 51 continues to move, the reversing gear 52 disengages from the lower rack 441 and begins to move on the upper rack 442. After the reversing gear 52 drives the rotating arm 51 to rotate counterclockwise by 90 degrees, the reversing gear 52 disengages from the upper rack 442, and the limiting groove 5111 of the drive shaft 511 engages with the convex strip 443 of the slide 44. The movable arm 51 no longer rotates with the cooperation of the limiting groove 5111 and the convex strip 443, so that the clamping plate 56 and the sample thereon remain in a horizontal state during the subsequent movement. When the conveying assembly 4 retracts the clamping plate 56 into the cleaning chamber 11, the reversing gear 52 finally stops at the end of the lower rack 441 away from the cleaning barrel 2, and the clamping plate 56 is vertically upward again. When the pressure plate 63 is not inserted, the pressure spring 55 pulls the clamping plate 56 toward the fixed clamping plate 54 to open the clamping plate 56. When the pressure plate 63 is inserted, the pressure plate 63 squeezes the clamping plate 56 away from the fixed clamping plate 54, closes the clamping plate 56, and stretches the pressure spring 55. When the pressure plate 63 detaches from the clamping plate 56, the stretched pressure spring 55 recovers its deformation to open the clamping plate 56 again.

[0040] The difference from the above embodiment is that both sides of the movable ring 61 are fixedly connected with a mounting seat 611, the clamping cylinder 612 is fixedly connected to the mounting seat 611, and a connecting rod 66 is provided on the outer side of the friction plate 64 and the fixed plate 65. The friction plate 64 is rotatably connected with the connecting rod 66 thereon, and the fixed plate 65 is fixedly connected with the connecting rod 66 thereon. One end of the connecting rod 66 is slidably connected in the mounting seat 611 and is fixedly connected to the output shaft of the clamping cylinder 612. A sliding rod 661 is welded on the connecting rod 66. The sliding rod 661 is located on one side of the clamping cylinder 612 and slides through the mounting seat 611. A movable groove 641 is provided on the outer side of the friction plate 64, and the movable groove 641 is located below the connecting rod 66.

[0041] The friction assembly 6 also includes a friction motor 67, which is fixedly mounted on the outer side of the connecting rod 66 on the friction plate 64. The output shaft of the friction motor 67 penetrates the connecting rod 66 and extends to the lower side of the connecting rod 66. An eccentric wheel 671 is coaxially fixedly connected to the extended end of the output shaft of the friction motor 67. An eccentric shaft 6711 is eccentrically arranged on the eccentric wheel 671. The eccentric shaft 6711 fits in the movable groove 641. The outer sides of the friction plate 64 and the fixed plate 65 are both welded with a protrusion 68 color detector 8. The protrusion 68 color detector 8 is located at one end of the two away from the movable ring 61.

[0042] Before cleaning the sample, the clamping cylinder 612 retracts the friction plate 64 and the fixed plate 65 to keep them away from the sample. When cleaning the sample, the clamping cylinder 612 pushes the friction plate 64 and the fixed plate 65 to contact the sample, and then the friction motor 67 drives the eccentric wheel 671 to rotate. The eccentric wheel 671 cooperates with the movable groove 641 through the eccentric shaft 6711 thereon, so that the friction plate 64 swings back and forth on the sample. The sample is scrubbed through the dynamic and static cooperation of the friction plate 64 and the fixed plate 65.

[0043] The difference from the above embodiment lies in that a cover plate 112 is hingedly mounted on the discharge port 111, a fixing seat 113 is fixedly mounted on the bottom of the cleaning chamber 11, a notch is formed on the fixing seat 113, a driving motor 114 is fixedly mounted on the inner wall of one side of the cleaning chamber 11, the position of the driving motor 114 corresponds to the notch of the fixing seat 113, a driving pulley 1141 is coaxially fixedly mounted on the output shaft of the driving motor 114, a drainage pump 3 is fixedly mounted in the cleaning chamber 11, the drainage pump 3 is located on one side of the cleaning barrel 2, a drainage pipe 31 is connected to the drainage pump 3, and one end of the drainage pipe 31 extends out of the detection cabinet 1.

[0044] Before the device is used, the cover plate 112 closes the discharge port 111 , and when placing the sample, the cover plate 112 is opened, and after the clamping plate 56 is retracted into the cleaning chamber 11 , the cover plate 112 is closed.

[0045] The difference from the above embodiment is that the cleaning barrel 2 includes a water storage barrel 21, a filter barrel 22 and a impeller 23. The water storage barrel 21 is fixedly mounted on the fixing seat 113, the filter barrel 22 is coaxially fixedly connected in the water storage barrel 21, a heater 211 is fixedly mounted at the bottom of the water storage barrel 21, the heater 211 is located between the inner wall of the water storage barrel 21 and the outer wall of the filter barrel 22, one side of the upper end of the water storage barrel 21 is connected with a water injection pipe 212, the water injection pipe 212 extends to the outside of the detection cabinet 1, the upper end of the impeller 23 is rotatably mounted on the bottom of the filter barrel 22, the lower end of the impeller 23 penetrates the filter barrel 22 and the water storage barrel 21 and extends into the notch of the fixing seat 113, the lower end of the impeller 23 is coaxially fixedly connected with a driven pulley 231, the driven pulley 231 is located in the notch of the fixing seat 113, the driven pulley 231 is connected to the driving pulley 1141 through a transmission belt 24, and one side of the lower end of the water storage barrel 21 is connected with a drain pipe 31.

[0046] Among them, before cleaning the sample, an appropriate amount of cleaning water is injected into the water storage barrel 21 through the water injection pipe 212. During this process, the heater 211 will heat the water in the water storage barrel 21 to an applicable temperature. The driving motor 114 drives the impeller 23 to rotate through the transmission belt 24. The rotation of the impeller 23 forms a vortex in the filter barrel 22, so that the cleaning agent and hot water are fully mixed. When cleaning the sample, the clamping plate 56 inserts the sample into the filter barrel 22, and the sample is cleaned under the action of the vortex and the friction component 6. After cleaning is completed, the driving motor 114 stops working, and the drain pump 3 discharges the water in the cleaning barrel 2 through the drain pipe 31.

[0047] The difference from the above embodiment is that a hot air blower 7 is fixedly installed below the drying chamber 12, and the drying chamber 12 and the hot air blower 7 are connected through an air supply duct 71;

[0048] A baffle 131 is fixedly connected in the detection chamber 13, and the baffle 131 corresponds to the chromaticity detector 8 of the protrusion 68. A chromaticity detector 8 is also installed in the detection chamber 13, and the chromaticity detector 8 is located on one side of the baffle 131. Fill lights 132 are fixedly installed on both sides of the chromaticity detector 8. A display screen 14 is fixedly installed above the detection cabinet 1, and the display screen 14 is located above the detection chamber 13. The display screen 14 is connected to the chromaticity detector 8 through electrical signals. A side door 15 is rotatably provided on one side of the detection cabinet 1, and the side door 15 corresponds to the detection chamber 13.

[0049] When the clamping plate 56 brings the sample into the drying chamber 12, the hot air blower 7 delivers hot air to the drying chamber 12 through the air supply duct 71 to dry the sample. When the clamping plate 56 enters the detection chamber 13, the clamping plate 56 first passes through the baffle 131. During this process, the rotating arm 51 pushes the protrusion 68 and the color detector 8 to contact the baffle 131. The baffle 131 pushes the movable ring 61 and the friction plate 64 and the fixed plate 65 thereon away from the clamping plate 56 through the protrusion 68 and the color detector 8, and compresses the support spring 62, so that the cleaned sample on the clamping plate 56 is exposed, and the clamping plate 56 is opened, and the sample is obtained. After the sample on the clamping plate 56 reaches the top of the colorimetry detector 8, the conveying motor 41 stops working for a while, and the fill light 132 illuminates the sample so that there is no shadow in the detection area of ​​the sample. After the colorimetry detector 8 detects the sample, it feeds back the detection result to the display screen 14 through an electrical signal. The inspector opens the side door 15, takes the sample off and then closes the side door 15. Then the conveying motor 41 retracts the rotating arm 51 into the cleaning chamber 11. During this process, the protrusion 68 of the colorimetry detector 8 disengages from the baffle 131, and the compressed support spring 62 pushes the movable ring 61 close to the clamping plate 56 again to close the clamping plate 56.

[0050] Example 2

[0051] The difference from the above embodiment is that a laser sensor 9 is installed in each of the drying chamber 12 and the detection chamber 13 , and both laser sensors 9 are connected to the conveying motor 41 through electrical signals.

[0052] When the clamping plate 56 reaches the drying chamber 12, the laser sensor 9 therein is triggered, and the laser sensor 9 causes the conveying motor 41 to suspend operation for a period of time. When the clamping plate 56 reaches the detection chamber 13, the laser sensor 9 therein is triggered, and the laser sensor 9 causes the conveying motor 41 to suspend operation for a period of time again.

[0053] A method for detecting dyeing of polyester fabrics uses a color fastness detection device.

[0054] Working principle: When in use, first pour water for cleaning samples into the cleaning barrel 2, and add cleaning agent into the cleaning barrel 2 through the discharge port 111. During this process, the heater 211 will heat the water in the water storage barrel 21 to a suitable temperature, and the driving motor 114 drives the impeller 23 to rotate through the transmission belt 24. The rotation of the impeller 23 forms a vortex in the filter barrel 22, so that the cleaning agent and hot water are fully mixed. At this time, the rotating arm 51 is located on the side of the cleaning barrel 2 away from the drying chamber 12, and the clamping plate 56 thereon is vertically directed to the bottom of the filter barrel 22. Before placing the sample, the telescopic cylinder 53 extends the output shaft to extend the clamping plate 56 out of the discharge port 111 to place the sample. When the clamping plate 56 does not start to clamp the sample, the support spring 62 pushes the movable ring 61 to approach one side of the clamping plate 56, and the movable ring 61 pushes the pressing plate 63 to close the clamping plate 56. When placing the sample, the inspector manually pushes the movable ring 61 downward, and the movable ring 61 pulls the pressing plate 63 away from the clamping plate 56, opens the closed clamping plate 56, and compresses the support spring 62 to place the sample. The sample is placed in the opened clamping plate 56, and then the movable ring 61 is released. The support spring 62 recovers its deformation and pushes the movable ring 61 close to the clamping plate 56 again. The opened clamping plate 56 is closed by the pressure plate 63, so that the clamping plate 56 fixes and clamps the sample. After that, the telescopic cylinder 53 retracts the clamping plate 56 into the cleaning chamber 11, and the conveying motor 41 drives the threaded rod 42 to rotate in the opposite direction, so that the driving member 45, under the guidance of the guide rod 43, drives the rotating arm 51 to move a certain distance toward the drying chamber 12 and then stops moving. During the process, the reversing gear 52 rotates clockwise with the cooperation of the lower rack 441. After the reversing gear 52 drives the rotating arm 51 to turn 180 degrees, the reversing gear 52 comes to the other end of the lower rack 441, and one side of the reversing gear 52 starts to mesh with one end of the upper rack 442, so that the clamping plate 56 is vertically downwardly aligned with the cleaning barrel 2. The telescopic cylinder 53 inserts the clamping plate 56 and the sample thereon into the cleaning barrel 2, and starts to clean the sample. Before cleaning the sample, the clamping cylinder 612 retracts the friction plate 64 and the fixing plate 65 to keep them away from the sample.

[0055] During the cleaning process, the clamping cylinder 612 pushes the friction plate 64 and the fixed plate 65 toward the sample until the friction plate 64 and the fixed plate 65 collide with the sample, and then the friction motor 67 drives the eccentric wheel 671 to rotate. The eccentric wheel 671 cooperates with the movable groove 641 through the eccentric shaft 6711 thereon to make the friction plate 64 swing back and forth on the sample. The friction plate 64 and the fixed plate 65 cooperate with each other to scrub the sample. After the sample is cleaned, the friction assembly 6 stops working and the telescopic air stops working. The cylinder 53 retracts the clamping plate 56 and the sample thereon, the driving motor 114 stops working, the drainage pump 3 discharges the water in the cleaning bucket 2 through the drainage pipe 31, and then the conveying assembly 4 drives the rotating arm 51 to continue to move toward the drying chamber 12. During this process, the reversing gear 52 disengages from the lower rack 441 and starts to move on the upper rack 442. After the reversing gear 52 drives the rotating arm 51 to rotate counterclockwise by 90 degrees, the reversing gear 52 disengages from the upper rack 442, and the limiting groove 511 of the driving shaft 511 is driven. 1 is fitted onto the convex strip 443 of the slideway 44, and the rotating arm 51 stops rotating under the cooperation of the limiting groove 5111 and the convex strip 443, so that the clamping plate 56 and the sample thereon are kept in a horizontal state in the subsequent movement. After the sample enters the drying chamber 12, the conveying assembly 4 stops working for a period of time, the clamping cylinder 612 drives the friction plate 64 and the fixing plate 65 away from the sample, and the hot air blower 7 delivers hot air to the drying chamber 12 through the air supply duct 71 to dry the sample, and the conveying motor 41 starts again , the dry sample is sent to the detection chamber 13, the baffle 131 pushes the movable ring 61 and the friction plate 64 and the fixed plate 65 thereon away from the clamping plate 56 through the protrusion 68, and the colorimetry detector 8 exposes the cleaned sample on the clamping plate 56, and the colorimetry detector 8 completes the detection with the cooperation of the fill light 132. After the detection is completed, the conveying assembly 4 drives the rotating arm 51 back to the cleaning chamber 11, and the reversing gear 52 finally stops at the end of the lower rack 441 away from the cleaning barrel 2, and the clamping plate 56 is vertically upward again.
