Description

Technical Field

[0001] The present invention relates to the technical field of powder coating performance detection, in particular to a device for detecting powder coating. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigments, fillers and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. During the production process of powder coating, its various properties need to be tested, including adhesion testing.

[0003] During use, the existing powder coating adhesion detection device fixes the object sprayed with powder coating, and then uses a high-pressure blower to blow a large amount of gas to impact the powder coating on the surface of the object to observe whether the powder coating on the surface of the object is detached. However, this detection method is relatively simple and cannot simulate the adhesion of powder coatings in different environments. At the same time, the wind blowing takes a long time, which reduces the detection efficiency and thus reduces the use value of the detection device. Summary of the Invention

[0004] The present invention discloses a device for detecting powder coatings, which aims to solve the technical problem that in the existing powder coating adhesion detection device, after fixing an object sprayed with powder coating, a large amount of gas is blown out by a high-pressure blower to impact the powder coating on the surface of the object, and whether the powder coating on the surface of the object is detached is observed. However, this detection method is relatively simple and cannot simulate the adhesion of powder coatings in different environments. At the same time, the wind blowing takes a long time, which reduces the detection efficiency.

In this case, the adhesive tape is replaced with a more sticky adhesive tape, and it is tested again. The adhesion level of the powder coating is obtained through layer-by-layer screening. This method of powder coating adhesion testing is efficient and fast, and the test results can be reflected intuitively, thereby improving the detection efficiency and detection effect, thereby improving the use value of the detection device.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The device for detecting powder coating disclosed in the present invention is mainly applicable to the existing powder coating adhesion detection device. During use, after fixing the object sprayed with powder coating, a large amount of gas is blown out by a high-pressure blower to impact the powder coating on the surface of the object to observe whether the powder coating on the surface of the object is detached. However, this detection method is relatively simple and cannot simulate the adhesion of powder coating in different environments. At the same time, the wind blowing takes a long time, which reduces the detection efficiency.

[0036] In a specific application scenario, when conducting a powder coating adhesion test, the object sprayed with powder coating is clamped on the test table 1, and then the adhesive tape plate 2101 is pressed onto the powder coating so that the adhesive tape plate 2101 is tightly adhered to the powder coating, and then the motor is started to drive the adhesive tape plate 2101 to reel up, so that the adhesive tape plate 2101 and the powder coating are quickly separated. If the powder coating is reeled up synchronously with the adhesive tape plate 2101, then there is a big problem with the adhesion of the powder coating. If there is no powder coating attached to the adhesive tape plate 2101, it means that the adhesion of the powder coating is strong. In this case, the adhesive tape plate 2101 is replaced with a more sticky adhesive tape plate 2101, and it is tested again. The adhesion level of the powder coating is obtained through layer-by-layer screening. This method of powder coating adhesion testing is efficient and fast, and the test results can be reflected intuitively, thereby improving the test efficiency and test effect, thereby improving the use value of the detection device.

The wound adhesive strip 2101 is then directly removed from the reel 2107. The docking sleeve 2106 on the outside of the new adhesive strip 2101 is then inserted onto the outside of the reel 2107. The third electric telescopic rod 2117 then drives the extrusion pieces 2118 to re-extrude and re-restrict the new adhesive strip 2101. This allows the adhesive strip 2101 to be quickly replaced.

The air pump 2305 inputs gas between the two stacking plates 2307, and the gas is heated by the electric heating tube 2308. When the gas pressure increases, the limit spring rod 2306 is passively stretched, and the heated gas is ejected through each heating hole 2309 to heat the powder coating. After heating for a period of time, the powder coating is tested again by the detection mechanism 21, thereby obtaining the adhesion test result of the powder coating under high-temperature baking.

[0044] It should be noted that during the heating process, the regulating cylinder 2303 drives the sinking ring rod 2304 to move to the bottom, and the heating part of the powder coating is sealed by the expanded telescopic sealing sleeve 2302, thereby improving the heating effect and reducing the time required for heating.

[0047] Working principle: When in use, clamp the object sprayed with powder coating on the test table 1, then press the adhesive tape plate 2101 to the powder coating, adjust the electric telescopic rod 2109 to drive the pressing roller 2111 to contact and squeeze the adhesive tape plate 2101, then adjust the telescopic rod 1 to drive the pressing roller 2111 to press the adhesive tape plate 2101, so that the adhesive tape plate 2101 and the powder coating are quickly adhered, and then start the motor to drive the adhesive tape plate 2101 to reel, so that the adhesive tape plate 2101 and the powder coating are quickly adhered. If the powder coating is wound up synchronously with the adhesive tape 2101, then the adhesion of the powder coating has a big problem. If there is no powder coating attached to the adhesive tape 2101, then the adhesion of the powder coating is strong. In this case, the adhesive tape 2101 is replaced with a more sticky adhesive tape 2101 and tested again. The adhesion level of the powder coating is obtained through layer-by-layer screening. Then, factors are added to the powder coating adhesion test. The factor addition module 1 is moved to 23. Move to the bottom of the detection mechanism 21, start the air pump 2305, and energize the electric heating tube 2308. The air pump 2305 inputs gas between the two stacking plates 2307, and the gas is heated by the electric heating tube 2308. When the gas pressure increases, the limit spring rod 2306 is passively stretched, and the heated gas is ejected through each heating hole 2309 to heat the powder coating. After heating for a period of time, the powder coating is tested again by the detection mechanism 21, thereby obtaining the adhesion test result of the powder coating under high-temperature baking. After the high-temperature baking test of the powder coating, the drive motor 16 is started and rotated 180°, and the factor adding module 24 is rotated to the bottom of the detection mechanism 21, and the vibration rod 2402 is started. The vibration rod 2402 transmits the vibration effect to the powder coating through the vibration rod 2406, adds the vibration factor to the powder coating, and then performs adhesion testing on it, and obtains the adhesion test result of the powder coating under the vibration state again. After the multiple tests are completed, the object sprayed with powder coating is removed and the operation is ended.
