[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0020] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] As attached Figure 1 , Attachment Figure 2 The present invention shows a device for testing the light-blocking properties of polyester fabric. The device comprises a base plate 1, on which spaced supports 2 are mounted. A rotating shaft 3 is connected between the two supports 2 and is horizontally rotatably connected to the supports 2. A driven gear 4 is mounted on the rotating shaft 3 and is fixedly connected to the rotating shaft 3. A motor 5 is mounted on the base plate 1, and the output end of the motor 5 is connected to a driving gear 6, which meshes with the driven gear 4. The motor 5 is used to drive the rotating shaft 3 forward and reverse within a certain angle. Side panels 7 are mounted on each end of the rotating shaft 3 near the supports 2. The side panels 7 are fixedly connected to the rotating shaft 3 and rotate synchronously with the rotating shaft 3. The side panels 7 have first openings 71 for the polyester fabric 10 to pass through. A xenon lamp 8 is mounted between the side panels 7 and is fixedly connected to the base plate 1. The xenon lamp 8 is located above the polyester fabric 10 to simulate sunlight. An illumination detection device 9 is mounted below the polyester fabric 10 to detect the light transmittance of the polyester fabric 10.

[0022] As attached Figure 3 As shown, the side panel 7 has a cavity inside, in which a movable plate 11 is installed. The movable plate 11 is machined with a second opening 112 corresponding to the first opening 71. Cylinders 12 connected to the side panels 7 are installed on both sides of the first opening 71. The output end of the cylinder 12 is connected to the movable plate 11. The cylinder 12 drives the movable plate 11 to move between a first position and a second position. When in the first position, the first opening 71 and the second opening 112 coincide with each other, allowing the polyester cloth 10 to pass smoothly through the opening. When in the second position, the first opening 71 and the second opening 112 are offset, and the polyester cloth 10 is stuck between the two side panels 7.

[0023] In this embodiment, the cylinder 12 is located on the outside of the side plate 7, and a vertical channel 72 connecting to the cavity is opened on the side plate 7. A connecting piece 13 is installed at the output end of the cylinder 12, and the connecting piece 13 is connected to the movable plate 11 through the channel 72. The cylinder 12 drives the movable plate 11 to reciprocate up and down along the channel 72, so that the polyester cloth 10 can be intermittently detected.

[0024] The driven gear 4 is located between the side plate 7 and the support 2. Limit blocks 14 connected to the bottom plate 1 are installed on both sides of the side plate 7. When the side plate 7 rotates to the limit position along with the rotating shaft 3, it abuts against the limit blocks 14 to prevent excessive rotation. The bottom of the side plate 7 is curved, and the contact surface between the limit blocks 14 and the side plate 7 is an arc surface, making the contact more gentle and avoiding collision.

[0025] When in use, the polyester cloth 10 enters from the opening of one side panel 7 and leaves from the opening of the other side panel 7. When the movable plates 11 on both sides move upward under the drive of the cylinder 12, the first opening 71 and the second opening 112 are staggered. The polyester cloth 10 is fixed between the two side panels 7. The xenon lamp 8 above the polyester cloth 10 provides a lighting environment simulating sunlight. The illumination detection device 9 below the polyester cloth 10 detects the light passing through the polyester cloth 10 and obtains data to judge the light-shielding property of the polyester cloth 10. The starting motor 5 can rotate the side panels 7 so that the polyester cloth 10 between the two side panels 7 is tilted at the same angle, as shown in the attached figure. Figure 4 As shown, when the side panels 7 rotate to their limit, they are stopped by the stoppers 14, preventing damage to the fabric caused by excessive rotation. Polyester fabric 10 used in different applications requires different levels of shading. When the fabric is tilted, the illumination is detected to prevent direct light. When the fabric is tilted, different illumination data is obtained at different positions of the illumination detection device 9. The shading parameters of the polyester fabric 10 can be analyzed and determined based on the changes in data obtained at different distances from the light source, resulting in the most appropriate results and selection of the most suitable fabric.
