Description

Technical Field

[0001] This invention relates to the field of household goods testing technology, specifically to an automatic household goods testing instrument. Background Technology

[0002] Home furnishings are a general term for various products that cover family living scenarios and meet daily living needs. As a core home textile category that combines decoration and functionality, curtains' safety, quality, and performance directly affect residents' health and living experience. Formaldehyde emission is related to indoor air safety, color fastness determines appearance durability, and light transmittance is closely related to privacy protection and lighting needs. Therefore, home furnishings need to be tested during the production process to provide efficient and accurate technical support for the quality control of curtain products, so as to ensure residential safety and improve the comfort of home life.

[0003] Current home furnishing testing devices require manual cutting of curtain samples for formaldehyde testing, followed by quantitative analysis using laboratory spectrophotometry. Colorfastness testing involves manually rubbing the sample with a cotton rubbing head and visually assessing the degree of color fading against a standard color chart. Light transmittance testing requires fixing the curtain sample on a spectrometer test platform, manually adjusting the sample position, and then reading the data. Because these testing methods introduce subjective errors due to manual operation, and each testing instrument operates independently, the testing cycle is long and the integration of multiple index data is difficult, making it difficult to meet the needs of large-scale production and efficient quality inspection. To address these issues, existing automatic home furnishing testing instruments employ automated actuators and multi-sensor integrated structures. These instruments utilize multiple types of sensors to simultaneously collect target parameters, and the main control unit analyzes and processes the collected data, improving the automation and efficiency of the testing. However, in practical use, existing integrated testing instruments, when simulating the actual use environment of curtains, only test the colorfastness of the sample by rubbing it with a single material. This fails to reproduce the performance loss scenarios under different rubbing materials, affecting the accuracy of the test results in assessing the actual performance of the product.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figure 2 , Figure 3 and Figure 4 This invention provides an automatic household goods testing instrument, including a housing 1. A replacement mechanism 2 is provided on the right side inside the housing 1. The replacement mechanism 2 is used to replace rollers of different materials to rub the sample. Conveying ports 5 are provided on the bottom of both the left and right sides of the housing 1. Conveying mechanisms 3 are provided on the inner side of the two conveying ports 5. Conveying mechanisms 3 are used to convey the sample. An installation plate 6 is fixedly connected to the top right side of the inner wall of the housing 1. An adjustment mechanism 4 is provided at the bottom of the installation plate 6. The adjustment mechanism 4 is used to adjust the wavelength of the light. The replacement mechanism 2 includes two turntables 21. The opposite sides of the two turntables 21 are rotatably connected to the front and rear ends of the right side of the inner wall of the outer casing 1. The turntables 21 serve as mounting carriers for gears 24 and friction rollers 23. Rotation allows for switching the positions of different friction rollers 23. A common connecting rod 22 is fixedly connected between adjacent middle sections of the two turntables 21. The connecting rod 22 connects the central axis of the two turntables 21, ensuring that the front and rear turntables 21 rotate synchronously. Multiple gears 24 are rotatably connected to the rear side of the front turntable 21. Gears 24 receive power by meshing with gears 28, driving the friction rollers 23 to rotate and achieve friction. The rear ends of the multiple gears 24 are all fixedly connected to friction rollers 23. The surfaces of the multiple friction rollers 23 are covered with different materials, directly contacting and rotating with the sample to simulate friction scenarios of different materials. The rear ends of the multiple friction rollers 23 rotate with the front end of the rear turntable 21. The outer wall of the outer casing 1 is connected to a servo motor 25 fixedly connected to the front right side. The output end of the servo motor 25 passes through the front end of the outer casing 1 and is fixedly connected to the front end of the corresponding turntable 21. The servo motor 25 provides rotation power to the turntable 21. The servo motor 25 is a 57HS22 model. The angle control ensures that the target friction roller 23 meshes with the gear 28. The outer wall of the outer casing 1 is connected to a drive motor 26 fixedly connected to the bottom right side. The drive motor 26 provides power for the rotation of the friction roller 23. The output end of the drive motor 26 passes through the front end of the outer casing 1 and is fixedly connected to a rotating shaft 27. The rotating shaft 27 is used to transmit the power of the drive motor 26 to the gear 28. The rear end of the rotating shaft 27 is fixedly connected to the gear 28. The gear 28 transmits the power of the drive motor 26 to the friction roller 23 by meshing with the corresponding gear 24. The gear 28 meshes with the corresponding gear 24. Specifically, servo motor 25 starts, and its output shaft drives the front turntable 21 to rotate around the center. Through connecting rod 22, it synchronously drives the rear turntable 21 to rotate, causing multiple circumferentially distributed friction rollers 23 to move in a circular motion with gear 24. When the friction roller 23 of the target material rotates to directly above gear 28, servo motor 25 stops, and gear 24 corresponding to the friction roller 23 meshes with gear 28. During detection, drive motor 26 starts, and the rotation at the output end is transmitted to gear 28 through shaft 27. Gear 28 drives the corresponding gear 24 to rotate, which in turn drives the friction roller 23 to rotate. The surface of the friction roller 23 contacts the sample conveyed below, generating friction. Through the rotation of servo motor 25, friction rollers 23 of different materials can be quickly switched, making the detection results close to the actual working conditions.

[0022] Reference Figure 3 , Figure 5 and Figure 6The conveying mechanism 3 includes two supports 31 and a transmission belt 34. The left and right ends of the opposite sides of the two supports 31 are fixedly connected to the inner wall of the corresponding conveying port 5. The supports 31 provide the mounting base. The left and right ends of the adjacent sides of the two supports 31 are rotatably connected to transmission wheels 32. The left and right sides of the adjacent sides of the two supports 31 are provided with connecting rods 33. The connecting rods 33 are used to connect the corresponding transmission wheels 32 on both sides to ensure that the transmission wheels on both sides rotate synchronously. The front and rear ends of the two connecting rods 33 are fixedly connected to one side of the corresponding transmission wheel 32. The multiple transmission wheels 32 are respectively connected by the corresponding transmission belts 34. The transmission belts 34 enable the synchronous rotation of the transmission wheels 32. Two drive wheels 32 on the side rotate synchronously. A perforated conveyor belt 35 is fixedly connected between adjacent drive belts 34. The perforated conveyor belt 35 carries and transports the sample, while its mesh design ensures light and airflow penetration. A drive assembly 38 is located on the right side of the front support 31. The conveying mechanism 3 also includes a tension roller 36, which provides tension to the sample to prevent it from loosening and shifting or wrinkling. The front and rear ends of the tension roller 36 are rotatably connected to one side of the corresponding support 31. A winding roller 37 is rotatably connected to the right end of adjacent supports 31. The rotation of the winding roller 37 allows the completed sample to be transported... The drive assembly 38, which includes a connecting shaft 381 and a transmission belt 384, is used for exporting, winding, and storing. The rear end of the connecting shaft 381 is rotatably connected to the right side of the front wall of the front support 31. The connecting shaft 381 connects the transmission wheel 383 and the transmission wheel 32, transmitting power. The bottom right side of the support 31 is rotatably connected to the connecting shaft 382, ​​which connects the transmission wheel 383 and the winding roller 37, transmitting driving power to the winding roller 37 to synchronize the winding and conveying actions. The front ends of both the connecting shaft 381 and the connecting shaft 382 are fixedly connected to the transmission wheel 383. The two transmission wheels 383 are connected to the transmission belt 384. 84 transmission connection, transmission belt 2 384 enables the two transmission wheels 2 383 to rotate synchronously, servo motor 2 385 is fixedly connected to the front right side of the outer wall of the outer shell 1, servo motor 2 385 provides power, and the running speed of the conveyor belt and the winding roller 37 is controlled by speed adjustment. Servo motor 2 385 is model 60ST-M00630. The output end of servo motor 2 385 is fixedly connected to the front end of the corresponding transmission wheel 2 383. The rear end of connecting shaft 1 381 passes through the front end of the front bracket 31 and is fixedly connected to the front end of the corresponding transmission wheel 1 32. The rear end of connecting shaft 2 382 passes through the front end of the front bracket 31 and is fixedly connected to the front end of the winding roller 37. Specifically, after the servo motor 385 starts, its output drives the corresponding transmission wheel 383 to rotate. The transmission wheel 383 drives another transmission wheel 383 to rotate via the transmission belt 384, causing the connecting shaft 381 and connecting shaft 382 to rotate synchronously. The rear end of the connecting shaft 381 passes through the front bracket 31 and is fixed to the right transmission wheel 32, thereby driving the transmission wheel 32 to rotate. The two transmission wheels 32 on the same side achieve synchronous operation via the transmission belt 34. At the same time, the connecting rod 33 connects the two transmission wheels. Connecting 32 ensures that the rotation speed of the two drive wheels 32 is consistent. The perforated conveyor belt 35 moves horizontally in a circular motion with the drive belt 34. The sample, which is laid flat on the top left side of the perforated conveyor belt 35, is sent into the detection area from the left conveyor port 5 of the outer shell 1. The tension roller 36 provides tension to the sample to eliminate slack. After the sample is detected, it moves to the right side with the conveyor belt. The connecting shaft 382 drives the winding roller 37 to rotate synchronously. The surface of the winding roller 37 contacts the sample and sends the sample out from the right conveyor port 5 and winds it up for storage.

[0023] Reference Figure 1 , Figure 3 and Figure 7 The adjustment mechanism 4 includes a focusing cover 41, the top of which is fixedly connected to the bottom front side of the mounting plate 6. The focusing cover 41 concentrates the light emitted by the xenon lamp 42, enhancing the light intensity and directionality. The xenon lamp 42 is installed on the top of the inner wall of the focusing cover 41. The xenon lamp 42 is the light source for detecting illumination. A drive shaft 43 is rotatably connected to the bottom rear side of the mounting plate 6. The drive shaft 43 transmits the power of the servo motor 46 to the wheel 44. The bottom of the drive shaft 43 is fixedly connected to the wheel 44, which is the mounting carrier for the filter 45. By rotating the wheel 44, different wavelength filters 45 are switched to focus. Below the cover 41, multiple filters 45 are fixedly connected to the inner side of the wheel 44. The multiple filters 45 are optical lenses of different wavelengths. A servo motor 46 is fixedly connected to the top right side of the outer wall of the housing 1. The servo motor 46 ensures that the target filter 45 is aligned with the condenser cover 41 by angle control. The servo motor 46 is a 42HS03 model. The output end of the servo motor 46 passes through the bottom of the housing 1 and the mounting plate 6 and is fixedly connected to the top of the drive shaft 43. The bottom position of the condenser cover 41 matches the position of the corresponding filter 45. The position of the xenon lamp 42 matches the position of the photosensitive sensor 18. Specifically, after the xenon lamp 42 is turned on, it emits light. The light is reflected by the reflective layer on the inner wall of the condenser 41 and converges downward. The beam passes through the filter 45 to form a natural lighting simulation, which directly illuminates the sample surface below. When it is necessary to simulate a specific wavelength of light, the servo motor 46 is started. The output end drives the wheel 44 to rotate through the transmission shaft 43. The servo motor 46 stops after the filter 45 moves to the bottom of the condenser 41. The xenon lamp 42 beam is filtered by the filter 45 to form a specific wavelength to illuminate the sample, realizing accurate simulation of different wavelength lighting scenarios. At the same time, the photosensitive sensor 18 receives the light passing through the sample in real time and calculates the transmittance.

[0024] Reference Figure 1 , Figure 3 and Figure 8 The top left side of the outer shell 1 is connected to a water supply pipe 7, which is used to connect an external water source and a distribution pipe 9 to supply water to the atomizing nozzles 10. A solenoid valve 8 is installed at the bottom of the outer wall of the water supply pipe 7. The solenoid valve 8 is a 4V210-08 model. The bottom of the water supply pipe 7 is connected to a distribution pipe 9, which distributes the water flow from the water supply pipe 7 to multiple atomizing nozzles 10. Multiple atomizing nozzles 10 are installed at the bottom of the distribution pipe 9. The atomizing nozzles 10 atomize the water flow and spray it evenly onto the sample to increase humidity. A vent 11 is opened at the top of the outer shell 1. The vent 11 is an air circulation channel in the chamber and provides an exhaust path for the dehumidifying fan 13. A mounting frame 12 is fixedly connected to the inner wall of the vent 11. The mounting frame 12 is used to fix the dehumidifying fan 13. The dehumidifying fan 13 is fixedly connected to the inner wall of the mounting frame 12. The dehumidifying fan 13 can exhaust the humid air in the chamber and reduce the humidity in the chamber. Specifically, when simulating a humid environment, the temperature and humidity sensor 15 detects that the humidity inside the chamber is lower than the set value. By opening the solenoid valve 8, external water flows into the diversion pipe 9 through the water supply pipe 7. The diversion pipe 9 distributes the water flow to the atomizing nozzle 10, which atomizes the water flow and sprays it onto the sample surface, quickly increasing the air humidity. When simulating a dry environment, the dehumidifying fan 13 is activated. The fan draws out the humid air inside the chamber through the ventilation port 11, reducing the humidity inside the chamber.

[0025] Reference Figure 3 , Figure 5 and Figure 8Heating elements 14 are fixedly connected to the left ends of the front and rear sides of the inner wall of the outer shell 1. The heating elements 14 raise the temperature inside the chamber by heating when energized. A temperature and humidity sensor 15 is fixedly connected to the middle of the rear side of the inner wall of the outer shell 1. The temperature and humidity sensor 15 is used to collect the temperature inside the chamber in real time. The temperature and humidity sensor 15 is a model SHT40. A color sensor 16 is fixedly connected to the right side of the inner wall of the outer shell 1. The color sensor 16 collects the RGB color values ​​of the sample rubbing area and calculates the color difference value to evaluate the color fastness grade of the sample. The color sensor 16 is a model TCS34725. The same support plate 17 is fixedly connected to the right side between the two adjacent brackets 31. The support plate 17 is used to fix the photosensitive sensor 18. A photosensitive sensor 18 is set on the top right side of the support plate 17. The photosensitive sensor 18 is a model BH1750. The photosensitive sensor 18 receives the light passing through the sample and converts it into an electrical signal to calculate the transmittance. Specifically, when a high-temperature environment needs to be simulated, the heating element 14 works to raise the temperature inside the chamber. Data is collected in real time by the temperature and humidity sensor 15, which can simulate different temperature and humidity environments. The color sensor 16 is aligned with the sample friction area below the friction roller 23. During the friction process, the RGB color value of the sample is collected in real time, the color difference value before and after friction is calculated, and the color fastness level is determined. The photosensitive sensor 18 fixed by the support plate 17 is aligned with the central axis of the xenon lamp 42 and the filter 45. It receives the light passing through the sample and converts it into an electrical signal. The transmittance is calculated in combination with the incident light intensity.

[0026] Working principle: After the curtain sample is smoothly fed into the housing 1 and positioned, the drive motor 26 starts and drives the gear 28 to rotate through the rotating shaft 27. The gear 28 meshes with the corresponding gear 24, causing the friction roller 23 in the working position to rotate synchronously and rub the surface of the curtain sample conveyed below. The color fastness is tested in conjunction with the color sensor 16. When it is necessary to simulate friction scenarios of different materials, the servo motor 25 starts and drives the front turntable 21 to rotate through the output end. The turntable 21 rotates around the central axis and drives the rear turntable 21 to rotate synchronously through the connecting rod 22. The remaining friction rollers 23 move along the circumferential trajectory with the gear 24. The servo motor 25 controls the rotation angle of the turntable 21 to ensure that the gear 24 of the friction roller 23 of the target material is aligned with the gear 28 and meshes. The drive motor 26 starts again and can drive the friction rollers 23 of other materials to rotate. Multiple material friction contact scenarios can be simulated as needed, and the test results are closer to the actual use conditions. During operation, servo motor 2 385 starts, driving the corresponding transmission wheel 2 383 to rotate. Through transmission belt 2 384, it drives another transmission wheel 2 383 to rotate synchronously, and causes connecting shaft 1 381 and connecting shaft 2 382 to rotate synchronously. The rear end of connecting shaft 1 381 is fixedly connected to the transmission wheel 1 32 on the right side of the front bracket 31, thereby driving the transmission wheel 1 32 to rotate. Through transmission belt 1 34, the transmission wheel 1 32 on the same side and the transmission wheel 1 32 on the other side connected by connecting rod 2 33 rotate synchronously, causing the hollow conveyor belt 35 fixed between the two transmission belts 1 34 to move horizontally. The sample to be tested is laid flat on the left side of the hollow conveyor belt 35. The conveyor belt carries the sample from the left conveyor port 5 of the outer shell 1 into the testing area. The tension roller 36 provides tension to the sample to prevent the sample from loosening and causing displacement or wrinkles. The sample moves to the right side with the conveyor belt. Connecting shaft 2 382 drives the winding roller 37 to rotate. The surface of the winding roller 37 contacts the sample, and the sample is exported from the right conveyor port 5 and wound up for storage. Finally, during sample testing, the xenon lamp 42 is activated and emits broad-spectrum light. The light is reflected and focused by the condenser 41, and shines vertically downward onto the filter 45 on the wheel 44. After passing through the filter 45, the beam forms a detection beam of a specific wavelength, which shines onto the sample surface below. When different lighting scenarios need to be simulated, the servo motor 46 is activated, and its output drives the wheel 44 to rotate around the central axis through the transmission shaft 43. The servo motor 46 controls the rotation angle, so that the wheel 44 rotates to a preset angle, causing the filters 45 of other wavelengths to move directly below the condenser 41 and stop. After the xenon lamp 42 beam is filtered by the new filter 45, it outputs light of the corresponding wavelength, realizing the switching of the illumination wavelength. The photosensitive sensor 18 is installed below the sample to collect the intensity of light passing through the sample in real time, simulating the effect of different wavelengths of light on the sample in the natural environment.
