Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a high-transparency polypropylene transparency testing device. Background Technology

[0002] High-transparency polypropylene is a thermoplastic resin produced by polymerizing propylene. It has physical properties such as high transparency and good toughness. High-transparency polypropylene is a type of polypropylene (PP). Through specific production processes or additives, it can achieve higher transparency and better toughness. High-transparency polypropylene maintains both high transparency and good toughness. When testing the transparency of high-transparency polypropylene, a high-transparency polypropylene transparency testing device is required. A light source is shone on the object to be tested, the light energy transmitted through the sample is measured, and compared with the reference value without the sample, thereby calculating the transparency value.

[0003] Patent document CN219161984U discloses an acrylic film transparency testing device, which includes a worktable. The worktable is characterized by having an upper support assembly and a lower support assembly symmetrically arranged at its upper and lower ends. The upper support assembly includes a first support plate and a second support plate fixedly mounted on the worktable. A sliding column is fixedly arranged between the first and second support plates, and a slider is slidably mounted on the sliding column. A detection assembly is provided within the slider. By incorporating an unwinding assembly and a tensioning assembly, the acrylic film can be easily tensioned, and the lateral position of the acrylic film can be adjusted for testing, ensuring stability during testing. Furthermore, by incorporating a driving assembly, when reciprocating motion of the first and second test heads is required for uniform testing, simply rotating the driving handle will drive the first and second test heads to reciprocate, facilitating uniform measurement of the acrylic film's transparency.

[0004] However, the acrylic film transparency testing device mentioned in the above-mentioned literature mainly considers the convenience and uniformity of measuring the transparency of the acrylic film, but it is not convenient to block the observation area of ​​the observable frame as needed to avoid the influence of strong external light on the test results.

[0005] In view of this, it is necessary to develop a light-blocking mechanism that can block the observation area of ​​the observable frame as needed to avoid the influence of strong external light on the test results. Utility Model Content

[0006] The purpose of this invention is to provide a high-transparency polypropylene transparency testing device to solve the technical problem of improving the testing accuracy of high-transparency polypropylene transparency testing devices mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-transparency polypropylene transparency testing device, comprising: a testing chassis, an observable frame installed on the outer wall of the testing chassis, and a light-shielding mechanism provided on the outer wall of the observable frame, the light-shielding mechanism being used to block the observation area of ​​the observable frame as needed to avoid strong external light affecting the test results;

[0008] The light-blocking mechanism includes a slide rod disposed outside the observable frame. A first slider is mounted around the outer wall of the slide rod, and a positioning block is mounted on the outer wall of the slide rod. The outer wall of the slide rod has a disassembly screw groove, and a disassembly screw is mounted on the inner wall of the disassembly screw groove. An electric slide rail is mounted on the outer wall of the observable frame, and a second slider is mounted on the output end of the electric slide rail. A light-blocking curtain is mounted on the outer wall of the second slider, and a first Velcro fastener is mounted on the outer wall of the light-blocking curtain. A second Velcro fastener is mounted on the outer wall of the first Velcro fastener, and a dustproof cloth is mounted on the outer wall of the second Velcro fastener.

[0009] Preferably, a test device plate is installed on the top of the observable frame, and a door panel is installed on the outer wall of the observable frame.

[0010] Preferably, the outer wall of the observable frame is provided with a moisture-proof mechanism, which is used to keep the inside of the observable frame dry at all times.

[0011] Preferably, the moisture-proof mechanism includes a moisture-proof frame, which is disposed on the outer wall of the observable frame.

[0012] Preferably, a dehumidifying fan is installed on the inner wall of the dehumidifying frame, an electric heating wire is installed on the inner wall of the dehumidifying frame, and a flow groove is provided on the inner wall of the dehumidifying frame.

[0013] Preferably, the inner wall of the observable frame is provided with a moisture-proof groove.

[0014] Preferably, the inner wall of the observable frame is provided with slots, the inner wall of the slots is fitted with a dustproof net, the inner wall of the observable frame is fitted with an angle motor, and the output end of the angle motor is fitted with a sealing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This utility model, by installing a light-shielding mechanism, can block the observation area of ​​the observable frame as needed, avoiding the influence of strong external light on the test results. Since external light shining into the inside of the observable frame will affect the test results, this needs to be improved. First, the electric slide rail drives the second slider to move, which opens the light-shielding curtain to block the observation area of ​​the observable frame. Then, the first and second Velcro fasteners are attached to the dustproof cloth to protect the light-shielding curtain from dust. At the same time, the light-shielding curtain can be removed by removing the removal screw from the removal screw groove. The electric slide rail and the second slider are connected by bolts and can be disassembled, thus avoiding the influence of external light on the test results.

[0017] 2. This utility model, by installing a moisture-proof mechanism, ensures that the interior of the observable frame remains dry at all times. When the observable frame is damp, it can lead to significant errors in the test results. Therefore, this needs to be improved. First, the moisture-proof fan and electric heating wire work to blow air through the moisture-proof groove to prevent moisture from entering the observable frame. Then, the angle motor drives the angle adjustment of the sealing plate, preventing it from sealing the groove holes, thus allowing air circulation inside the observable frame and further dehumidifying it. This avoids the situation where excessive moisture affects the test results and leads to significant errors, thereby improving accuracy. Attached Figure Description

[0026] Please see Figure 1 and Figure 2 A high-transparency polypropylene transparency testing device includes: a test chassis 1, an observable frame 2 installed on the outer wall of the test chassis 1, a test device plate 3 installed on the top of the observable frame 2, and a door panel 4 installed on the outer wall of the observable frame 2. The door panel 4 is opened, and then a glass slide coated with high-transparency polypropylene is placed in the observable frame 2. Then, the test device plate 3 emits light to test it, and the test result is displayed through the test chassis 1.

[0027] Please see Figure 1 and Figure 2The outer wall of the observable frame 2 is equipped with a light-shielding mechanism. This mechanism is used to block the observation area of ​​the observable frame 2 as needed, preventing strong external light from affecting the test results. The light-shielding mechanism includes a slide rod 5, which is located outside the observable frame 2. A first slider 6 is mounted around the outer wall of the slide rod 5. A positioning block 7 is mounted on the outer wall of the slide rod 5. A disassembly screw groove 8 is provided on the outer wall of the slide rod 5. A disassembly screw 9 is installed on the inner wall of the disassembly screw groove 8. An electric slide rail 10 is mounted on the outer wall of the observable frame 2. A second slider 11 is mounted on the output end of the electric slide rail 10. A light-shielding curtain 12 is mounted on the outer wall of the second slider 11. A first Velcro fastener 13 is mounted on the outer wall of the light-shielding curtain 12. A second Velcro fastener 13 is mounted on the outer wall of the first Velcro fastener 13. The outer wall of the second Velcro 14 is fitted with a dustproof cloth 15. Since external light can affect the test results when it shines on the inside of the frame 2, this needs to be improved. First, the electric slide rail 10 moves the second slider 11, which opens the light-blocking curtain 12 to block the observation area of ​​the frame 2. Then, the first Velcro 13 and the second Velcro 14 adhere to the dustproof cloth 15 to protect the light-blocking curtain 12 from dust. At the same time, the light-blocking curtain 12 can be removed. The light-blocking curtain 12 can be removed by removing the removal screw 9 from the removal screw groove 8. The electric slide rail 10 and the second slider 11 are connected by bolts and can be disassembled, thereby avoiding the influence of external light on the test results.

[0028] Please see Figure 3 and Figure 4 The outer wall of the observable frame 2 is equipped with a moisture-proof mechanism to ensure that the interior of the observable frame 2 remains dry. The moisture-proof mechanism includes a moisture-proof frame 16, which is disposed on the outer wall of the observable frame 2. A moisture-proof fan 17 is installed on the inner wall of the moisture-proof frame 16. An electric heating wire 18 is installed on the inner wall of the moisture-proof frame 16. A flow channel 19 is provided on the inner wall of the observable frame 2. A moisture-proof groove 20 is provided on the inner wall of the observable frame 2. A slot 21 is provided on the inner wall of the observable frame 2. A dustproof mesh 22 is installed on the inner wall of the slot 21. An angle electric... The output end of the angle motor 23 is equipped with a sealing plate 24. When the observable frame 2 is relatively humid, it will also lead to a large error in the test results. Therefore, it is necessary to improve this. First, the dehumidifying fan 17 and the electric heating wire 18 work to blow air and prevent moisture inside the observable frame 2 through the dehumidifying groove 20. Then, the angle motor 23 works to drive the angle adjustment of the sealing plate 24 so that it does not seal the groove hole 21, thereby allowing air to circulate inside the observable frame 2, thus preventing moisture and dehumidifying inside, avoiding the situation where the test results are greatly affected by the high humidity, and improving the accuracy.

[0029] Working principle: Open the door panel 4, then place the glass slide coated with high-transparency polypropylene into the observation frame 2. The testing device 3 then emits light to test it, and the test results are displayed on the testing chassis 1. Since external light can affect the test results when it shines into the inside of the observation frame 2, this needs to be improved. First, the electric slide rail 10 moves the second slider 11, causing the light-blocking curtain 12 to open and block the observation area of ​​the observation frame 2. Then, the first Velcro 13 and the second Velcro 14 attach to the dustproof cloth 15 to protect the light-blocking curtain 12 from dust. The light-blocking curtain 12 can also be removed by removing the removal screw 9 from the removal screw groove 8. The light-blocking curtain 12 can be disassembled, and the electric slide rail 10 and the second slider 11 can be disassembled by bolt connection, thereby avoiding the influence of external light on the test results. When the observable frame 2 is relatively humid, it will also lead to a large error in the test results, so this needs to be improved. First, the dehumidifying fan 17 and the electric heating wire 18 work to blow air and prevent moisture inside the observable frame 2 through the dehumidifying groove 20. Then, the angle motor 23 works to drive the angle adjustment of the sealing plate 24 so that it does not seal the groove hole 21, thereby allowing air to circulate inside the observable frame 2, thereby preventing moisture and dehumidifying inside, avoiding the situation where the test results are greatly affected by the high humidity, and improving accuracy.
