Description

Technical Field

[0001] The utility model relates to the technical field of light transmittance detection, in particular to a material light transmittance detection device. Background Art

[0002] The light transmittance of a material refers to the percentage of the luminous flux passing through a transparent or translucent body to the incident luminous flux, which reflects the efficiency of the material in transmitting light. When light hits the surface of a material, part of the light is reflected, scattered and absorbed, while the other part is transmitted. The light transmittance of a material is related to the thickness of the material and the absorption coefficient of light. Materials with high light transmittance can better transmit light, while materials with low light transmittance will have a greater blocking effect on light. The light transmittance detection equipment can detect the light transmittance of the material and obtain the light transmittance value of the material.

[0003] The existing Chinese patent with announcement number CN215297144U discloses a rapid detection device for material transmittance, including a fixed base plate, a sliding rail is bored at the outer end of the fixed base plate, a sliding pillar is slidably connected in the sliding rail, an ultraviolet light transmittance detector is installed on the upper end of the sliding pillar, a plurality of evenly distributed first pillars are fixedly connected to the upper end of the fixed base plate, a placement platform is fixedly connected to the upper end of the first pillar, a plurality of evenly distributed fixed plates are fixedly connected to the upper end of the placement platform, a limiting plate is fixedly connected to the outer end of the fixed plate, a sliding groove is bored at one end of the fixed plate close to the limiting plate, a clamping plate is slidably connected in the sliding groove, an insertion rod is inserted at the outer end of the limiting plate, and the insertion rod is rotatably connected to the clamping plate.

[0004] Although the above scheme can feed back sample data to the production line in time to improve work efficiency, light leakage still occurs during detection by the device, resulting in insufficient accuracy of the detected data. At the same time, the device cannot obtain intuitive data during manual observation and cannot make quick judgments, which affects the efficiency of detection. Therefore, it does not meet existing needs. In this regard, we propose a material transmittance detection device. Utility Model Content

[0027] It also includes a lifting seat 2, which is arranged on one side of the upper end of the base 1, and a threaded rod 7 is rotatably arranged inside the lifting seat 2, and a lifting block 9 is threadedly connected to the outer side of the threaded rod 7, and one end of the lifting block 9 extends to the outside of the lifting seat 2, and a light shielding box 10 is arranged at one end of the lifting block 9 located outside the lifting seat 2, and an optical signal receiver 11 is installed at the upper end of the light shielding box 10;

[0028] It also includes a sound and light alarm 4 which is installed on the upper end of the lifting seat 2 , and a display 5 is provided on one side of the upper end of the base 1 .

[0029] When in use, start the motor 6 to make the threaded rod 7 drive the lifting block 9 to rotate synchronously. Under the guidance of the guide rod 8, the rotation of the lifting block 9 is converted into vertical movement up and down. When the lifting block 9 moves downward, it will drive the light shielding box 10 to move downward synchronously, so that the lower end of the light shielding box 10 is stuck in the inside of the circular groove 13. The gap at the connection is reduced by the rubber pad 12, thereby preventing light and dust from entering the inside of the light shielding box 10, thereby ensuring the accuracy of detection.

[0030] See also Figure 2 , a motor 6 is provided at the lower end of the threaded rod 7, and the output end of the motor 6 is connected to the threaded rod 7 through a coupling transmission, and the motor 6 provides power for the lifting of the light shielding box 10;

[0031] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 A circular plate 16 is arranged above the testing platform 14, and handles 18 are arranged on the front and rear sides of the upper end of the circular plate 16. Reset springs 17 are arranged at the four corners of the upper end of the testing platform 14, and the reset springs 17 are connected to the circular plate 16. Under the elastic action of the reset springs 17, the circular plate 16 can be moved downward to quickly fix the test sample;

[0032] See also Figure 1A PLC controller 3 is installed at the front end of the lifting seat 2, the input end of the PLC controller 3 is electrically connected to the output end of the optical signal receiver 11, and the output end of the PLC controller 3 is electrically connected to the input ends of the sound and light alarm 4 and the display 5. The display 5 and the sound and light alarm 4 are arranged to facilitate the user's observation and judgment;

[0033] See also Figure 2 and Figure 3 A circular groove 13 is provided at the upper end of the base 1, and the circular groove 13 is adapted to the light shielding box 10. After the light shielding box 10 is inserted into the circular groove 13, light can be prevented from entering, thereby preventing light leakage;

[0034] See also Figure 3 , guide rods 8 are welded on the front and rear sides of the threaded rod 7, the guide rods 8 all penetrate the lifting block 9, and the guide rods 8 all slide with the lifting block 9, and the setting of the guide rods 8 realizes the vertical lifting of the lifting block 9;

[0035] See also Figure 1 and Figure 2 A rubber pad 12 is adhered and fixed to the lower end of the light shielding box 10. The setting of the rubber pad 12 can reduce the gap at the connection between the light shielding box 10 and the circular groove 13, and can prevent light and dust from entering the interior of the light shielding box 10 to avoid affecting subsequent detection.

[0036] Working principle: When in use, grasp the handle 18 and pull the circular plate 16 upward to stretch the reset spring 17, place the test sample on the upper end of the test table 14, and after releasing the handle 18, the circular plate 16 will move downward under the elastic recovery action of the reset spring 17 to clamp and fix the test sample, thereby realizing rapid fixation of the test sample and increasing the test efficiency. During the test, start the motor 6, and rotate the threaded rod 7 under the transmission of the coupling, and the threaded rod 7 will drive the lifting block 9 to rotate synchronously. Since the lifting block 9 is slidably matched with the two guide rods 8, the lifting block 9 will be axially limited, and the rotation of the lifting block 9 will be converted into vertical movement up and down, so that the lifting block 9 moves downward, and the lifting block 9 will drive the light shielding box 10 to move downward synchronously, so that the lower end of the light shielding box 10 is stuck in the inner part of the circular groove 13. The gap at the connection is reduced by the rubber pad 12, so as to prevent light and dust from entering the interior of the light shielding box 10, thereby ensuring the accuracy of the detection, and starting the light source box 15 to emit light, which is received by the optical signal receiver 11. The optical signal receiver 11 can convert the optical signal into an electrical signal and transmit it to the PLC controller 3. The PLC controller 3 can send the transmittance data to the display 5 and display it, which is convenient for the user to observe intuitively. The user sets the standard value of the transmittance through the PLC controller 3 in advance. When detecting, the PLC controller 3 will compare the received transmittance with the preset standard value of the transmittance. When it exceeds or falls below the preset value, the PLC controller 3 will start the sound and light alarm 4 to quickly remind the user and improve the efficiency of the detection.
