Description

Technical Field

[0001] This utility model belongs to the technical field of time measuring instruments, and specifically relates to a powder coating gelation time measuring instrument. Background Technology

[0002] Powder coatings, as a new type of pollution-free coating, have been widely used for the decoration of metal and other surfaces. The gelation time of powder coatings, as an important test indicator, plays a crucial role in the quality of powder coatings. The gelation time of powder coatings is the time required for a certain volume of powder coating to melt and become a non-deformable material under specified conditions. In the existing technology, the traditional gelation time tester measures the powder coating by spreading it flat in a groove on a copper heating block.

[0003] Chinese Patent No. CN216718274U discloses a powder coating gelation time tester, which relates to the technical field of time testers. Specifically, it is a powder coating gelation time tester, which includes a support platform. A heat insulation cover is fixedly installed on the left side of the upper surface of the support platform, and a measuring instrument is installed on the right side of the upper surface of the support platform. A sliding groove is opened at the bottom of the inner cavity of the heat insulation cover, and a slider is movably installed in the sliding groove at the bottom of the inner cavity of the heat insulation cover. The sliding groove at the bottom of the inner cavity of the support platform is five to ten centimeters away from the left and right ends of the slider.

[0004] However, the above structure still has some shortcomings. Although the scraper and other structures can scrape the residual paint, the scraping method and the scraping point are all located in the tank. The scraped residual paint will always remain in the tank, and the user will need to clean the residual paint in the tank later, which is very inconvenient. Utility Model Content

The powder coating gelation time tester is a device specifically designed to evaluate the time required for powder coatings to transition from a molten state to a gelled state. This instrument features a precise temperature control system that simulates the heating process of powder coatings in practical applications and records its gelation time. This indicator is crucial for understanding the curing speed, leveling properties, and selection of curing accelerators for powder coatings. The powder coating gelation time tester is characterized by its ease of operation, precise temperature control, and reliable test results, and is widely used in powder coating production, quality control, and R&D. During use, the coating can be directly placed into the protective shell 12 through the feed port 4 for convenient feeding, and also facilitates connection with the heating block 18. After relative processing, it can be relatively tested by measuring instrument body 21.

The bottom of the sealing plate 5 is made of magnetic material. The bottom of the sealing plate 5 is in contact with the top of the magnet 11. Due to the presence of the magnet 11, the attraction of the magnet 11 can effectively limit the sealing plate 5 to prevent displacement when the sealing plate 5 covers the feeding port 4. The first groove 9 also facilitates the up and down sliding of the sealing plate 5 so as to push or pull the sealing plate 5 to move.

The handle 29 is concave in shape and the corners of the handle 29 are arc-shaped. The opening of the third groove 27 facilitates the movement of the collection box 28. The handle 29 is easy for the user to grip. The collection box 28 can be directly pulled out through the handle 29, which facilitates the user to transfer and process the collected residual paint later.

[0030] Operating principle and advantages: During use, the paint can be directly placed into the protective shell 12 through the feeding port 4 for convenient feeding. This also allows for relative treatment with the heating block 18. The measuring instrument 21 can then perform relative testing. The insulation cover 3 effectively protects the outer perimeter of the protective shell 12, providing good insulation and improving the stability of the measurement. After the measurement is completed, the user can turn the screw 15, and the rotating shaft 16 will rotate the end of the screw 15 in its original position. The entire protective shell 12 will then move along the second sliding groove 13, moving it to a position close to the opening 22. Then, the electric push rod 19 is activated to push the heating block 18, which will then be pushed out of the protective shell 12 for relative cleaning of residual paint. The cleaned residual paint can also fall directly into the collection box 28 through the opening 22 for unified collection. Due to the presence of the first telescopic rod 17 and the second telescopic rod 20, the connection points can be adjusted without hindering the adjustment of the height of the heating block 18 and the position of the protective shell 12. The secondary support and limiting function effectively improves the stability of the height adjustment of the heating block 18 and the position adjustment of the protective shell 12. Due to the presence of the magnet 11, the attraction of the magnet 11 can effectively limit the sealing plate 5 to prevent displacement when the sealing plate 5 covers the feeding port 4. Its first sliding groove 9 also facilitates the up-and-down sliding of the sealing plate 5, so as to push or pull the sealing plate 5 to move. Due to the opening of the rectangular opening 6, the user can directly view the inside of the heat preservation cover 3 through the transparent glass 7 without opening the sealing plate 5, which is conducive to the user's constant observation of the coating measurement status. Due to the presence of the rubber pad 26, which is a rubber product, it has good anti-slip ability and rubber shock absorption ability, and can also distribute the force area at the bottom of the support leg 2, thereby effectively improving the stability of the support plate 23 position installation. Due to the opening of the third sliding groove 27, it is convenient to move the collection box 28. Its handle 29 is convenient for the user to grab, and the collection box 28 can be directly pulled out through the handle 29, which is convenient for the user to transfer and process the collected residual coating later.
