Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a device for testing the color fastness of fabrics. Background Technology

[0002] Colorfastness refers to the ability of textiles to retain their original color after various treatments, such as washing, sun exposure, and friction. The quality of colorfastness directly affects the lifespan and appearance of textiles.

[0003] When testing the colorfastness of fabrics to wash, a certain number of steel balls need to be manually counted and added to the fabric testing cup. This process needs to be repeated for each fabric testing cup, which is not only tedious but also prone to inconsistencies in the number of steel balls, potentially resulting in too few or too many balls being added. Therefore, it is essential to design a device for testing the colorfastness of fabrics. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a device for testing the color fastness of fabrics.

[0005] The objective of this utility model can be achieved through the following technical solution: A device for testing the color fastness of fabrics, comprising a base, characterized in that the base has a conveyor belt, which is driven to rotate by a power motor; the conveyor belt has a plurality of flexible positioning rings for positioning fabric testing cups, and the flexible positioning rings are evenly distributed; a fixing plate is installed on the base, and a steel ball storage box, a housing, and a steel ball inlet tube are sequentially installed on the fixing plate from top to bottom; a feeding mechanism is provided inside the housing to quantitatively inject steel balls from the steel ball storage box into the steel ball inlet tube; a photoelectric sensor is installed on the base, and the photoelectric sensor is located directly below the steel ball inlet tube.

[0006] The material handling mechanism includes a vertical plate, a cylinder, a guide rail, a slider, a movable seat, an auxiliary seat, and a material handling platform. The vertical plate is installed inside the machine housing. The guide rail is horizontally connected to the vertical plate. The slider is slidably connected to the guide rail. The movable seat is connected to the slider. The auxiliary seat is connected to the movable seat via a spring. The material handling platform is detachably connected to the auxiliary seat and is located in the through channel at the bottom of the steel ball storage box. The material handling platform includes a flat, enclosed part and a material handling part with several material handling holes. The cylinder is installed on the vertical plate, and the piston rod end of the cylinder is connected to the movable seat.

[0007] A vibration motor is also installed on the auxiliary seat.

[0008] The material handling platform also has a slot, the auxiliary seat has a positioning protrusion that matches the slot, and the auxiliary seat is also threaded with a locking screw.

[0009] An electrical control box is also installed on the base, and the photoelectric sensor, power motor, cylinder and vibration motor are all electrically connected to the electrical control box via wiring.

[0010] The base also has height-adjustable support legs and casters.

[0011] Compared with existing technologies, this device for testing the color fastness of fabrics has the following advantages:

[0012] In this invention, when testing the color fastness of fabrics, the fabric test cup is placed on a conveyor belt, which transports it to the bottom of the steel ball inlet tube. The feeding mechanism can automatically add a fixed amount of steel balls into the fabric test cup, eliminating the need for manual counting of steel balls and significantly improving the efficiency of the fabric color fastness test.

Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figures 1-3As shown, the device for testing the color fastness of fabrics includes a base 1, a conveyor belt 4 on the base 1, and a motor driving the conveyor belt 4 to rotate. The conveyor belt 4 has several flexible positioning rings 4a for positioning the fabric test cup. The flexible positioning rings 4a adopt an existing structure and are evenly distributed. A fixing plate 9 is installed on the base 1. From top to bottom, a steel ball storage box 7, a housing 8, and a steel ball inlet tube 10 are installed on the fixing plate 9. The housing 8 is equipped with a feeding mechanism that can quantitatively inject steel balls from the steel ball storage box 7 into the steel ball inlet tube 10. A photoelectric sensor 11 is installed on the base 1 and is located directly below the steel ball inlet tube 10.

[0019] The material handling mechanism includes a vertical plate 18, a cylinder 20, a guide rail 15, a slider 16, a movable seat 17, an auxiliary seat 21, and a material handling platform 13. The vertical plate 18 is installed inside the housing 8. The guide rail 15 is horizontally connected to the vertical plate 18. The slider 16 is slidably connected to the guide rail 15. The movable seat 17 is connected to the slider 16. The auxiliary seat 21 is connected to the movable seat 17 via a spring 19. The material handling platform 13 is detachably connected to the auxiliary seat 21 and is located in the through channel 7a at the bottom of the steel ball storage box 7. The platform 13 includes a flat, enclosed section 13b and a material-retrieving section 13a with several material-retrieving holes. In this embodiment, when the material-retrieving section 13a is located within the through channel 7a, steel balls can be automatically replenished into the material-retrieving section 13a. As the material-retrieving platform 13 moves outside the steel ball storage box 7, the steel balls in the material-retrieving section 13a automatically fall downwards into the steel ball inlet pipe 10. The cylinder 20 is mounted on the upright plate 18, and the piston rod end of the cylinder 20 is connected to the moving seat 17. In this embodiment, a door 6 is also hinged to the housing 8.

[0020] A vibration motor 22 is also installed on the auxiliary seat 21. With this structure, the material handling table 13 can be made to vibrate slightly as needed, so that the steel balls can be quickly replenished into the material handling section 13a.

[0021] The material handling platform 13 also has a slot 13c, and the auxiliary seat 21 has a positioning protrusion 21a that cooperates with the slot 13c. The auxiliary seat 21 is also threaded with a locking screw 14. With this structure, different material handling platforms 13 can be easily replaced. At the same time, its disassembly and assembly are also relatively convenient and quick.

[0022] An electrical control box 12 is also installed on the base 1. The photoelectric sensor 11, the power motor, the cylinder 20 and the vibration motor 22 are all electrically connected to the electrical control box 12 through the circuit. This adopts the existing technology, and its circuit does not need to be redesigned.

[0023] The base 1 also has height-adjustable support legs 2 and casters 3.

[0024] In this invention, when conducting a fabric color fastness test, the fabric test cup is placed on a conveyor belt, which transports it to below the steel ball inlet tube 10. The material handling mechanism can automatically add a fixed amount of steel balls into the fabric test cup, eliminating the need for manual counting of steel balls and significantly improving the efficiency of the fabric color fastness test.

[0025] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
