Description

Technical Field

[0001] This utility model relates to the field of textile fabric testing technology, specifically a device for testing the light transmittance of curtain fabric. Background Technology

[0002] In the textile industry, the light transmittance of curtain fabric is a crucial performance indicator. It refers to the ability of light to pass through the curtain fabric, directly affecting the curtain's performance in terms of indoor lighting regulation, privacy protection, and decorative effect. As people's living standards improve and their requirements for living environments continue to rise, different usage scenarios have different needs for the light transmittance of curtain fabrics. For example, bedrooms may require fabrics with high light-blocking properties to ensure a good sleeping environment, while living rooms may prefer fabrics with moderate light transmittance to create a comfortable lighting atmosphere. Therefore, accurately testing the light transmittance of curtain fabrics is of great significance for fabric research and development, production, and quality control. It can ensure that products meet the actual needs of different users and enhance market competitiveness.

[0003] However, traditional curtain fabric light transmittance testing technology has many shortcomings. On the one hand, the structure of traditional testing devices is relatively simple, and they usually lack precise light source control and a stable testing environment, making it difficult to simulate natural light of different intensities and angles, resulting in low accuracy and reliability of the test results. On the other hand, during the fixing and transmission of the fabric, traditional devices are prone to problems such as fabric wrinkles and displacement, which can significantly interfere with the light transmittance test results, making the test data unable to truly reflect the actual performance of the fabric. In addition, traditional testing technology has a low degree of automation, requiring a large amount of manual operation and data recording, which not only increases labor intensity but also easily introduces human error. At the same time, the testing efficiency is difficult to meet the needs of large-scale production. These shortcomings seriously affect textile enterprises' control over fabric quality and improvement of production efficiency. To address these issues, we propose a curtain fabric light transmittance testing device. Utility Model Content

Ceramic guide wheels are embedded in the through circular holes. The surface of the guide wheels is polished to reduce the resistance when the fabric is transported. At the same time, the axis of the guide wheels is perpendicular to the running direction of the conveyor belt 10, ensuring that the fabric always passes through the detection area in a straight line.

[0069] Working principle: First, the curtain fabric is placed on the auxiliary frame 18 of the feeding assembly. The rollers on the top of the auxiliary frame 18 reduce friction during fabric placement, facilitating smooth fabric movement. Next, the second motor 19 in the feeding auxiliary structure is started. The small pulley at the end of the output shaft of the second motor 19 drives the second pulley 20 on the side of the second gearbox 22 to rotate via the second belt 21, thereby driving the feeding frame 16 to rotate. At the same time, the telescopic cylinder 17 can adjust the angle of the feeding frame 16, allowing the fabric to be smoothly conveyed to the support structure at a suitable inclination. In the support structure, the rotating shaft 4 is rotatably installed in the bearing seats 3 linearly distributed on the top of the base plate 1, achieving flexible rotation through ball bearings. The transmission belt 10 on the outside of the rotating shaft 4 operates under the action of the drive assembly. After the first motor 6 of the drive assembly starts, the small pulley at the end of its output shaft drives the first pulley 7 on the outer wall of the first gearbox 9 to rotate via the first belt 8. The first gearbox 9 transmits power to the rotating shaft 4, which is fixedly connected to it, thereby driving the fabric to rotate. The conveyor belt 10 smoothly transports the fabric, allowing it to pass sequentially through the detection area within the light shield 2. Once the fabric enters the light shield 2, the detection components begin operation. The light strip 13 and high-intensity light source 14, slidably mounted in the side grooves of the detection frame 12 on the top of the detection table 11, can be adjusted in position according to detection requirements to simulate light sources of different intensities and angles. For example, the high-intensity light source 14 can provide strong light illumination, while the light strip 13 can supplement auxiliary light sources. Together, they form a stable detection environment within the light shield 2. The inlet / outlet 23 on both sides of the light shield 2 and the corresponding through-holes effectively isolate external light interference while ensuring fabric transport. During fabric transport, the conveyor belt 10 maintains smooth operation, preventing wrinkles or shifts in the fabric and ensuring it is flat for light detection. At this time, the light emitted by the light structure passes through the fabric, and the inspector can accurately assess the fabric's light transmittance by observing the degree of light transmission or recording transmittance data using relevant instruments.
