Description

Technical Field

[0001] This invention relates to the field of new material testing technology, specifically to a new material textile color fastness tester. Background Technology

[0002] Light fastness to sunlight is an important indicator for evaluating the ability of colored textiles to retain their color under sunlight, and it directly affects the quality and lifespan of the textiles. Currently, light fastness to sunlight testing usually adopts the xenon lamp accelerated aging test method, in which the sample to be tested is placed under a xenon lamp and the degree of fading of the sample is compared with that of a blue wool standard to determine the light fastness level.

[0003] However, existing light fastness testers often require changing samples, adjusting shielding parts, or repeating tests multiple times to compare different exposure times when testing samples under different lighting conditions. This method is not only cumbersome and inefficient, but also introduces additional errors due to individual differences between different samples, making it difficult to accurately reflect the true fading pattern of a single material. Summary of the Invention

[0004] The purpose of this invention is to provide a new material textile color fastness tester to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The blocking wheel meshes with the gear ring, and the gear ring and the turntable are rotatably connected to the chassis via a rotating cavity.

[0008] Furthermore, the moving block and the guide block are respectively engaged and slidably connected to the turntable and the chassis through guide grooves and guide rails, and the guide grooves are equidistantly distributed around the turntable.

A material tray is provided on the lower side of the chassis, and a rotating motor is provided below the material tray. Adjustment gears are provided on the edge of the material tray, and cleaning gears are provided on the upper edge of the chassis.

[0010] Furthermore, the top of the inner wall of the housing is symmetrically provided with brackets, and lamp tubes are placed between the brackets. A light shield is provided on the outside of the lamp tube. Sliding rods are symmetrically provided on both sides of the lamp tube on the bracket. A dust scraper is provided between the lamp tube and the light shield, and a top rod is connected to one side of the dust scraper. The inner and outer walls of the dust scraper are respectively attached to the lamp tube and the light shield. A light-transmitting glass is provided at the bottom of the light shield. The dust scraper is slidably connected to the sliding rod, and the top rod is slidably connected to the bracket.

[0011] Furthermore, a return spring is connected between the push rod and the inner wall of the housing, and a cam plate is provided on one side of the push rod. A shaft is connected to one side of the cam plate, and a sleeve is provided on the outer side of the shaft. A transmission gear is connected to the lower end of the sleeve, and a buffer spring is connected inside the sleeve.

[0012] Furthermore, the push rod is elastically connected to the housing via a return spring, the sleeve is connected to the shaft via a spline, and the sleeve is also elastically connected to the shaft via a buffer spring. The transmission gear meshes with the cleaning wheel teeth.

[0013] Furthermore, an air inlet pipe is provided on one side of the housing, and an air distribution pipe is connected to one end of the air inlet pipe inside the housing. A flow limiting plate is provided on the upper part of the air distribution pipe, and an air guide cone is connected inside the air distribution pipe. A bottom frame is provided on the side of the air distribution pipe near the bracket, and a dust collection box is provided inside the bottom frame. A ring pipe is provided at the lower part of the air distribution pipe, and air outlets are symmetrically opened on the inner side of the ring pipe.

[0014] Furthermore, an air guide plate is rotatably connected inside the air outlet, and an adjusting rod is provided in the center of the air guide plate. A threaded sleeve is connected to the lower end of the adjusting rod, and a lead screw is threadedly connected to the inner side of the threaded sleeve. An adjusting gear is connected to the lower end of the lead screw, and the adjusting gear is rotatably connected to the housing through a shaft seat. The adjusting gear meshes with the adjusting wheel teeth, and the adjusting rod is slidably connected to the annular tube.

[0015] Furthermore, an oil cylinder is fitted to one side of the light shield, and a top plug is installed inside the oil cylinder. A top plate is connected to one side of the top plug, and the top plate is connected to the flow limiting plate.

[0016] This invention provides a new type of light fastness tester for textile materials, which has the following beneficial effects: During use, the sample can be gradually shaded from the outside to the inside, so that the same sample can be tested under different lighting conditions at the same time using the same equipment. When adjusting the shading, the lamp tubes can be cleaned and the air outlet angle can be adjusted simultaneously. When cooling the lamp tubes, the cooling air volume can be automatically adjusted according to the lamp tube temperature to avoid the lamp tube temperature being too high or too low. The cooling airflow can also be used to collect dust, preventing dust from flying around in the device.

[0017] 1. This invention can automatically complete gradient exposure testing for different exposure times on the same device without changing the same sample. It can obtain test results for multiple exposure times without changing the sample or adjusting the machine, which significantly improves the testing efficiency and eliminates data errors caused by individual sample differences. At the same time, the baffle movement trajectory is precisely constrained by the guide rail and guide block, so that the light-irradiated part at the center of the sample is always a regular octagon. This is conducive to the testers to make clear and regular observation and comparison of the fading area by visual inspection or instruments, thus improving the accuracy of the rating.

[0018] 2. When the chassis rotates, the present invention drives the dust scraper to slide against the inner wall of the light shield and the outer wall of the lamp tube through mechanical transmission between the cleaning gear teeth, transmission gears, cam plate and push rod components. This automatically cleans the inner wall of the light shield and the outer wall of the lamp tube, preventing dust accumulation from affecting the light or causing abnormal temperature rise. At the same time, after the cam plate rotates one revolution, the dust scraper can quickly return to its original position under the action of the return spring, preparing for the next cleaning. The slide rod restricts the movement of the dust scraper, ensuring that the cleaning action is stable and reliable and will not deviate, thereby protecting the light shield and lamp tube from damage. No separate motor or sensor is required, simplifying the overall structure.

[0019] 3. When cold air is introduced into the air inlet pipe to cool the lamp tube, the heat emitted by the lamp tube causes the oil in the oil cylinder to expand. The oil pushes the top plug upward, and through the top plate, it drives the flow-limiting plate to rise in the air distribution pipe, thereby increasing the flow area at the top of the air distribution pipe. This allows the flow rate of cold air entering the light shield to automatically increase as the temperature rises, achieving adaptive adjustment of the cooling airflow. This ensures that the lamp tube temperature remains stable within a suitable range, avoiding excessively high or low temperatures that could affect the test results or equipment lifespan. The airflow enters the light shield from the gaps in the upper part of the light shield and support under the action of the air guide cone, and is blocked by the dust scraper. During the return flow, the dust scraped off by the dust scraper is carried out through the gap between the light shield and the lower part of the bracket and sent into the dust collection box for collection, preventing dust from scattering inside the machine casing and achieving integrated cleaning and dust removal. When the material plate rotates, the adjusting wheel tooth drives the adjusting gear to rotate, which drives the threaded sleeve to rise through the lead screw, causing the adjusting rod to drive the air guide plate to rotate in the air outlet, adjusting the flow direction of the cold air so that the cold air can blow towards the baffle extending from the shielding groove, cooling the baffle and preventing it from heating up, expanding and deforming under long-term irradiation of the lamp tube, ensuring shielding accuracy and equipment stability.

[0028] Please see Figures 1 to 4The throttle handle 207 is elastically connected to the rotary groove 205 via a torsion spring 206, and is also connected to the blocking wheel 208 via a one-way bearing. The blocking wheel 208 meshes with the gear ring 209, and the gear ring 209 and the turntable 210 are rotatably connected to the chassis 201 via the rotating cavity 204. The shifting block 213 and the guide block 214 are respectively engaged and slidably connected to the turntable 210 and the chassis 201 via the guide groove 211 and the guide rail 203, respectively. The guide groove 211 is equidistantly distributed circumferentially about the turntable 210. The sidewall of block 214 fits against the sidewall of guide rail 203, and guide rail 203 has a regular octagonal structure. Limiting rods 3 are symmetrically connected to the lower surface of chassis 201, and pressure springs 4 are provided on the outer side of the limiting rods 3. A material tray 5 is provided on the lower side of chassis 201, and a rotating motor 6 is provided below the material tray 5. Adjusting gear teeth 7 are provided on the edge of the material tray 5. Cleaning gear teeth 8 are provided on the upper edge of chassis 201. Supports 9 are symmetrically provided on the top of the inner wall of the machine housing 1, and lamp tubes 10 are placed between the supports 9. A light shield 11 is provided on the outside of the lamp tube 10. A bracket 9 has symmetrically arranged sliding rods 12 on both sides of the lamp tube 10. A dust scraper 13 is provided between the lamp tube 10 and the light shield 11, and a top rod 14 is connected to one side of the dust scraper 13. The inner and outer walls of the dust scraper 13 are respectively in contact with the lamp tube 10 and the light shield 11. A light-transmitting glass is provided at the bottom of the light shield 11. The dust scraper 13 is slidably connected to the sliding rod 12, and the top rod 14 is slidably connected to the bracket 9. A reset mechanism is connected between the top rod 14 and the inner wall of the housing 1. A spring 15 is provided, and a cam plate 16 is provided on one side of the push rod 14. A shaft 17 is connected to one side of the cam plate 16, and a sleeve 18 is provided on the outside of the shaft 17. A transmission gear 19 is connected to the lower end of the sleeve 18, and a buffer spring 20 is connected inside the sleeve 18. The push rod 14 is elastically connected to the housing 1 through the return spring 15. The sleeve 18 is connected to the shaft 17 through a spline, and the sleeve 18 is elastically connected to the shaft 17 through the buffer spring 20. The transmission gear 19 meshes with the cleaning gear 8.

[0029] The specific operation is as follows: During use, open the rotating door on the front side of the casing 1, pull up the base plate 201 to place the circular sample in the center of the material placement plate, release the base plate 201, and under the action of the pressure spring 4, the base plate 201 will press the material firmly onto the material placement plate 5. Close the rotating door to turn on the lamp tube 10 to test the sample. During testing, rotating the motor 6 will drive the material placement plate 5 to rotate intermittently. The base plate 201 will rotate synchronously with the material placement plate 5 via the limit rod 3, allowing the sample to rotate. When the base plate 201 rotates, the handle 207 will be stopped by the stop block 215. The force of the obstruction causes the rotating plate 208 to rotate within the rotary groove 205, compressing the torsion spring 206 and driving the shielding wheel 208 to rotate via a one-way bearing. The gear ring 209, under the action of the shielding wheel 208, drives the turntable 210 to rotate within the rotating cavity 204. The moving block 213, under the action of the guide groove 211, drives the baffle 212 to move within the shielding groove 202. The guide rail 203 can restrict the movement trajectory of the baffle 212 via the guide block 214, so that when the baffle 212 shields the sample, when the handle 207 passes the stop block 215 as the chassis 201 rotates, the handle 207... 07 can rotate under the action of torsion spring 206, and because of the one-way bearing, it will not drive the shielding wheel 208 to rotate. Due to the diameter difference between the gear ring 209 and the shielding wheel 208, each rotation of the chassis 201 will only cause the shielding wheel 208 to drive the gear ring 209 to rotate by a small angle, so that the baffle 212 can shield the sample in a stepped manner. When the chassis 201 is pulled up, the chassis 201 will push the transmission gear 19 to drive the sleeve 18 to slide on the shaft 17 and compress the buffer spring 20. After the chassis 201 is lowered, the sleeve 18 will... The transmission gear 19 can be reset under the action of the buffer spring 20. When the chassis 201 rotates, the transmission gear 19 can be driven to rotate through the cleaning gear 8, thereby causing the sleeve 18 to drive the cam plate 16 to rotate through the shaft 17, pushing the push rod 14 to slide on the bracket 9. The push rod 14 drives the dust scraper 13 to move inside the light shield 11. After the cam plate 16 rotates one revolution, the push rod 14 can quickly drive the dust scraper 13 to reset under the action of the reset spring 15. The slide rod 12 can restrict the dust scraper 13 to prevent the dust scraper 13 from deflecting during the movement.

[0030] Please see Figures 3 to 6An air inlet pipe 21 is provided on one side of the casing 1, and one end of the air inlet pipe 21 located inside the casing 1 is connected to an air distribution pipe 22. A flow limiting plate 23 is provided on the upper part of the air distribution pipe 22, and an air guide cone 24 is connected inside the air distribution pipe 22. A bottom frame 25 is provided on the side of the air distribution pipe 22 near the bracket 9, and a dust collection box 26 is provided inside the bottom frame 25. An annular pipe 27 is provided at the lower part of the air distribution pipe 22, and air outlets 28 are symmetrically opened on the inner side of the annular pipe 27. An air guide plate 29 is rotatably connected inside the air outlet 28, and the center of the air guide plate 29 is... An adjusting rod 30 is provided, and a threaded sleeve 31 is connected to the lower end of the adjusting rod 30. A lead screw 32 is threadedly connected to the inner side of the threaded sleeve 31. An adjusting gear 33 is connected to the lower end of the lead screw 32. The adjusting gear 33 is rotatably connected to the housing 1 through a shaft seat. The adjusting gear 33 meshes with the adjusting gear teeth 7. The adjusting rod 30 is slidably connected to the ring tube 27. An oil cylinder 34 is attached to one side of the light shield 11. A top plug 35 is provided inside the oil cylinder 34. A top plate 36 is connected to one side of the top plug 35. The top plate 36 is connected to the flow limiting plate 23.

[0031] The specific operation is as follows: During use, cold air is introduced into the air intake pipe 21. After being split by the air distribution pipe 22, it can cool the lamp tube 10 and the chassis 201 respectively. When cooling the lamp tube 10, the airflow, under the action of the air guide cone 24, enters the light shield 11 from the gap between the light shield 11 and the upper part of the bracket 9. When it is blocked by the dust scraper 13 and flows back, it will carry the dust scraped off by the dust scraper 13 out from the gap between the light shield 11 and the lower part of the bracket 9 and send it into the dust collection box 26 for collection. The heat emitted by the lamp tube 10 will be transferred to the oil cylinder 34 through the light shield 11, causing the oil in the oil cylinder 34 to heat up and expand. When the oil pushes the top plug 35 to rise in the oil cylinder 34, it can drive the flow limiting plate 23 to rise in the air distribution pipe 22 through the top plate 36, thereby adjusting the flow area of ​​the upper part of the air distribution pipe 22. When the cold air flows from the ring pipe 27 through the air outlet 28 to cool the chassis 201, as the material plate rotates, the adjusting wheel tooth 7 will drive the adjusting gear 33 to rotate, thereby driving the threaded sleeve 31 to rise through the lead screw 32, so that the adjusting rod 30 drives the air guide plate 29 to rotate in the air outlet 28, thereby adjusting the flow direction of the cold air and allowing the cold air to blow towards the baffle 212 extending from the shielding groove 202 to cool the baffle 212.

[0032] In summary, when using this new material textile light fastness tester, first open the turntable on the front side of the casing 1, pull up the base plate 201 to place the circular sample in the center of the material plate, release the base plate 201, and under the action of the pressure spring 4, the base plate 201 will press the material onto the material plate 5. Close the turntable to turn on the lamp tube 10 to test the sample. When the base plate 201 is pulled up, the base plate 201 will push the transmission gear 19 to drive the sleeve 18 to slide on the shaft 17 and compress the buffer spring 20. After the base plate 201 is lowered, the sleeve 18 will drive the transmission gear 19 to reset under the action of the buffer spring 20. While ensuring that the transmission gear 19 meshes with the cleaning gear 8, the transmission gear will not obstruct the placement of the sample.

[0033] During testing, the rotating motor 6 can drive the material tray 5 to rotate intermittently. The chassis 201 rotates synchronously with the material tray 5 through the limiting rod 3, so that the sample can be rotated for comprehensive testing. When the chassis 201 rotates, the handle 207 will rotate in the rotary groove 205 due to the obstruction of the stop block 215, compressing the torsion spring 206 and driving the shielding wheel 208 to rotate through the one-way bearing. The gear ring 209 drives the turntable 210 to rotate in the rotating cavity 204 under the action of the shielding wheel 208. The moving block 213 drives the baffle 212 to move in the shielding groove 202 under the action of the guide groove 211. The guide rail 203 can limit the movement trajectory of the baffle 212 through the guide block 214, so that when the baffle 212 shields the sample, the light-irradiated part at its center is a regular octagon, which is convenient for observation.

[0034] When the throttle 207 passes the stop 215 as the chassis 201 rotates, the throttle 207 can rotate under the action of the torsion spring 206. Because of the one-way bearing, it will not drive the shielding wheel 208 to rotate. Due to the diameter difference between the gear ring 209 and the shielding wheel 208, each rotation of the chassis 201 will only cause the shielding wheel 208 to drive the gear ring 209 to rotate by a small angle. This allows the baffle 212 to provide stepped shielding for the sample, thereby performing gradient sunlight exposure testing on the sample. This allows for testing of the sample for different exposure times without changing the machine and the sample.

[0035] When the chassis 201 rotates, the cleaning gear 8 drives the transmission gear 19 to rotate, which in turn causes the sleeve 18 to drive the cam plate 16 to rotate via the shaft 17. This causes the push rod 14 to slide on the bracket 9. The push rod 14 drives the dust scraper 13 to move inside the light shield 11, thus cleaning the inner wall of the light shield 11 and the outer wall of the lamp tube 10. This prevents dust from accumulating on the lamp tube 10 or the light shield 11, which could affect the illumination or cause abnormal heating. After the cam plate 16 rotates one revolution, the push rod 14 can quickly drive the dust scraper 13 to return to its original position under the action of the return spring 15, so as to carry out the next cleaning. The slide rod 12 can restrict the dust scraper 13 to prevent it from tilting during movement and causing damage to the light shield 11 and the lamp tube 10.

[0036] During the testing process, cold air is introduced into the air intake pipe 21. After being split by the air distribution pipe 22, the lamp tube 10 and the chassis 201 are cooled respectively. When cooling the lamp tube 10, the airflow enters the light shield 11 from the gap between the light shield 11 and the upper part of the bracket 9 under the action of the air guide cone 24. When it is blocked by the dust scraper 13 and flows back, it will carry the dust scraped off by the dust scraper 13 out from the gap between the light shield 11 and the lower part of the bracket 9 and send it into the dust collection box 26 for collection, so as to prevent the dust from flying in the casing 1.

[0037] The heat emitted by the lamp tube 10 is transferred to the oil cylinder 34 through the light shield 11, causing the oil in the oil cylinder 34 to heat up and expand. The oil pushes the top plug 35 to rise in the oil cylinder 34, which in turn drives the flow limiting plate 23 to rise in the gas distribution pipe 22 through the top plate 36. This adjusts the flow area at the top of the gas distribution pipe 22. The higher the temperature in the light shield 11, the more the oil expands, the greater the distance the top plug 35 drives the flow limiting plate 23 to rise, the larger the flow area at the top of the gas distribution pipe 22, the greater the flow rate of cold air entering the light shield 11, and the higher the cooling efficiency. This achieves the effect of adaptive adjustment of the cooling air flow rate, ensuring that the temperature of the lamp tube 10 is not too high or too low.

[0038] When the cold air enters the ring pipe 27 from the air distribution pipe 22 and is blown out through the air outlet 28 to cool the chassis 201, as the material plate rotates, the adjusting wheel tooth 7 will drive the adjusting gear 33 to rotate, which in turn drives the threaded sleeve 31 to rise through the lead screw 32, so that the adjusting rod 30 drives the air guide plate 29 to rotate in the air outlet 28, thereby adjusting the flow direction of the cold air and allowing the cold air to blow towards the baffle 212 extending from the shielding groove 202, cooling the baffle 212 and preventing the baffle 212 from heating up and expanding and deforming under the illumination of the lamp tube 10.
