Description

Technical Field

[0001] This utility model belongs to the field of curtain testing technology, and in particular relates to a light-blocking test device for curtain processing. Background Technology

[0002] Curtains refer to curtains made of materials such as cloth, bamboo, reeds, hemp, gauze, plastic, and metal that are hung on windows to block or regulate indoor lighting. Testing the light-blocking performance of curtains is one of the steps in curtain manufacturing. It mainly involves placing the curtains inside a closed box, emitting light through turned-on lights, and using photoelectric sensors to detect the light intensity, thereby completing the test of the curtains' light-blocking performance.

[0003] A search revealed a light-shielding testing device for processing light-shielding adhesive tape, disclosed in patent publication number CN217156287U. The device includes a housing with a linear guide rail on its inner bottom wall, connected to a support via a slider. Through the interaction of the housing, linear guide rail, slider, lead screw, support, pressure plate, pen-shaped cylinder, first moving groove, first guide wheel, first connecting rod, second moving groove height, second guide wheel, first adjusting block, photoelectric sensor, second adjusting block, test light source, through groove, second connecting plate, first connecting plate, adjusting plate, empty groove, and second connecting rod, the device improves the accuracy of light-shielding test results for the light-shielding adhesive tape. It solves the problem in existing light-shielding film testing devices where the photoelectric sensor is far from the fixed position of the light-shielding film, causing rapid attenuation of light after passing through the film, making it difficult for the photoelectric sensor to detect changes in light and leading to deviations in the test results.

[0004] The aforementioned light-shielding testing device for processing light-shielding adhesive tape has a pressure plate connected to the top of the support, a silicone pad layer at the bottom of the pressure plate, and a pen-shaped cylinder connected to the rear side of the support. The top of the piston rod of the pen-shaped cylinder is hinged to the rear side of the pressure plate. Controlling the piston rod of the pen-shaped cylinder to retract causes the pressure plate to flip open. Then, the light-shielding adhesive tape to be tested is placed on top of the two supports, and the piston rod of the pen-shaped cylinder is extended again, forcing the pressure plate to press down and clamp the light-shielding adhesive tape. At this time, the relative position of the light-shielding adhesive tape and the support does not change. However, it is inconvenient to test the light-shielding performance of light-shielding adhesive tape while simultaneously winding and unwinding long pieces. Furthermore, a photoelectric sensor is installed on the top of the first adjusting block, and a second adjusting block is movably sleeved on the side surface of the second connecting rod. The interior of the second adjusting block has an installation groove, and a test light source is installed on the inner top wall of the installation groove. The photoelectric sensor is located directly below the test light source, and a first sealing gasket is installed on the top of the photoelectric sensor. A second sealing gasket is provided at the bottom of the segment block. A first connecting plate is fixedly connected to the front side of the first adjusting block, and a second connecting plate is fixedly connected to the front side of the second adjusting block. The first connecting plate is connected to the second connecting plate through an adjusting plate. A slot is opened on the inner wall of the front side of the box. The first and second connecting plates are both located inside the slot. The relative positions of the first and second adjusting blocks are adjusted by pushing the adjusting plate. At this time, the light-shielding film is located between the photoelectric sensor and the second connecting plate, and the bottom and top of the light-shielding film are respectively attached to the first and second sealing gaskets. When the photoelectric sensor and the test light source are moved to the position to be tested, the test light source switch is turned on, and the test light shines on the top of the light-shielding film. If the light-shielding performance of the light-shielding film is defective, the photoelectric sensor will detect a relatively drastic change in light. However, it is not easy to fill the gap between the light-shielding film and the inner wall of the box, and light will leak through the gap, which will adversely affect the accuracy of the light-shielding performance test of the light-shielding film.

[0005] To address this issue, we provide a light-blocking performance testing device for curtain manufacturing, which solves the problems mentioned above. Utility Model Content
