Description

Technical Field

[0001] This application relates to the technical field of light transmittance detection equipment, and in particular to an instrument for detecting the light transmittance of polymer materials. Background Art

[0002] In the field of materials, light transmittance detection is one of the important indicators for evaluating the optical properties of polymer materials. In the process of quality control and product research and development in the polymer materials industry, the accurate measurement of the light transmittance parameter is particularly important. A light transmittance detector is an instrument with an intelligent digital display screen for detecting the light transmittance of materials.

[0003] Currently, the detection hole of the existing polymer light transmittance detection instrument is located outside. After long-term placement, dust in the air will enter through the detection hole and deposit on the detection probe.

[0004] The detection probe located inside the detection hole is usually difficult to clean. When dust adheres to the detection probe, it will affect the light transmittance of the product to be detected, resulting in errors in the light transmittance detection results. Summary of the Utility Model

[0005] The purpose of this application is to provide an instrument for detecting the light transmittance of polymer materials to improve the problem of errors in light transmittance detection results.

[0006] An instrument for detecting the light transmittance of polymer materials provided by this application adopts the following technical solutions:

[0007] A polymer light transmittance detection instrument includes a body. The body is provided with a carrier table storage groove. A carrier table can be accommodated in the carrier table storage groove. A detection hole is provided on the carrier table, and a detection probe is in the detection hole.

[0008] By adopting the above technical solution, when the light transmittance detection instrument is not in use, the carrier table can be placed inside the carrier table storage groove, thereby reducing the time for the detection probe to be exposed outside the storage groove, which is beneficial to reducing the contamination of the detection probe and thus reducing the error of the light transmittance detection result.

[0009] Optionally, a slide rail is provided on the inner side wall of the carrier table storage groove, and the carrier table is connected to the inner side wall of the carrier table storage groove through the slide rail.

[0010] By adopting the above technical solution, when the light transmittance detection instrument is needed or the use is ended, pushing the carrier table will be smoother and more stable.

[0011] Optionally, a first magnet is provided on the carrier table, and a first adsorbent is provided on the inner side wall of the carrier table storage groove; when the carrier table is located in the carrier table storage groove, the first magnet and the adsorbent attract each other.

[0012] By adopting the above technical solution, when the light transmittance detector is not in use, the stage will be adsorbed and fixed in the stage storage groove, and will not slide out of the stage storage groove along the slide rail under the condition of table shaking or the like, so as to achieve the fixing effect.

[0013] Optionally, a second magnet is provided at one end of the inner side wall of the stage storage groove away from the first magnet, and when the stage is outside the stage storage groove, the second magnet attracts the adsorbent.

[0014] By adopting the above technical solution, when the light transmittance detector is in use, the stage will be adsorbed and fixed outside the stage storage groove and will not slide along the direction of the slide rail, so as to achieve the purpose that the stage is in a fixed state during use.

[0015] Optionally, a handle is provided on the side surface of the stage opposite to the stage storage groove.

[0016] By adopting the above technical solution, the stage can be moved more conveniently and quickly.

[0017] Optionally, a transparent pressing plate is provided on the upper surface of the stage above the detection hole, and the transparent pressing plate is detachably connected to the stage.

[0018] By adopting the above technical solution, when detecting the light transmittance of a sample, the sample will be firmly fixed on the stage, avoiding the movement of the sample during the detection process, thereby affecting the detection result.

[0019] Optionally, the transparent pressing plate is provided with a waist-shaped hole along its width direction, and an adjusting bolt threadedly connected to the stage is inserted into the waist-shaped hole.

[0020] By adopting the above technical solution, by adjusting the height of the adjusting bolt, the tightness between the pressing plate and the sample to be measured is adjusted, so as to realize loading or unloading of the sample. During this process, it is not necessary to completely disassemble the fixing parts, which is more convenient and labor-saving.

[0021] Optionally, the machine body is provided with a light emitter storage groove communicating with the stage storage groove, and a light emitter can be accommodated in the light emitter storage groove.

[0022] By adopting the above technical solution, when the light transmittance detector is not in use, the light emitter is stored in the light emitter storage groove, reducing contact with the outside world and reducing the possibility of being collided and damaged in the external environment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects.

[0024] When the polymer transmittance detection instrument is not in use, the body can be placed inside the stage storage slot, thereby reducing the time that the detection probe is exposed to the outside of the storage slot, which is beneficial to reduce the contamination of the detection probe and thus reduce the error of the transmittance detection result.

[0025] When the transmittance testing instrument is needed or finished, using the slide rail to move the stage will make the handling operation more stable and smooth.

[0026] The sample is fixed on the stage using a transparent pressing plate with an adjusting bolt. The height of the adjusting bolt can be adjusted to affect the tightness of the transparent pressing plate. There is no need to completely disassemble the sample fixing device, making the loading and unloading process more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

The plane is also provided with a first magnet 51 and a second magnet 53, which are respectively located at the two ends of the plane. The inner wall of the stage storage slot 1 is provided with an adsorption member 52 above the slide rail 4. The adsorption member 52 is a device that cooperates with the magnet. The adsorption member 52 is adsorbed on the first magnet 51 and the second magnet 53 through magnetic attraction, and is firmly fixed. A handle 8 is provided on the stage 2 on the opposite side of the stage storage slot 1, and the handle 8 is symmetrically located along the midline of the long side of the surface.

[0033] Refer to Figure 1 , at the center position of the upper surface of the stage 2 near one end of the stage storage groove 1, a support arm 9 is provided. The lower end of the support arm 9 is connected to the stage 2 and extends in a direction away from the upper surface of the stage 2. The upper end of the support arm 9 is connected with a light-emitting body 12, and the light-emitting body 12 is a basic optical device serving as the light source of the light transmittance tester. A detection hole 3 is provided on the upper surface of the stage 2, and the detection hole 3 is coaxial with the light-emitting body 12. The light-emitting body 12 irradiates the material to be measured located directly below, and the detection probe 31 receives the light refracted by the material to be measured. The body 13 converts the received light signal and transmits it to the computer, and the computer finally analyzes and obtains the light transmittance data of the material to be measured. The light-emitting body 12 in the stage 2 is electrically connected to the body 13 through a flexible power cord to realize power supply.
