Description

Technical Field

[0001] This utility model relates to the technical field of powder coating test chambers, and in particular to a powder coating UV aging test chamber. Background Technology

[0002] UV aging test chambers are laboratory equipment that accelerate the aging process of materials by simulating conditions such as ultraviolet radiation, temperature, and humidity in the natural environment. In the field of powder coatings, their application is mainly reflected in weather resistance testing and performance evaluation. They can simulate the natural aging process of months or even years in a few days to a few weeks, significantly shortening the research and development cycle.

[0003] In practical use, the material tray inside the existing UV aging test chamber needs to be positioned by a bracket, which is inconvenient to operate and is prone to falling off. In addition, the material tray lacks a support structure for powder coating samples, resulting in insufficient contact between the samples and the simulated environment, which affects the accuracy of the test. This paper proposes a powder coating UV aging test chamber to solve the above problems. Utility Model Content

[0004] To address the shortcomings and defects in existing technologies, this utility model proposes a powder coating UV aging test chamber. This chamber addresses the technical problems of existing UV aging test chambers where, in actual use, the material tray inside the chamber requires a support frame for positioning, which is inconvenient and prone to falling off. Furthermore, the lack of a support structure for the powder coating sample inside the material tray results in insufficient contact between the sample and the simulated environment, affecting the accuracy of the test.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A powder coating UV aging test chamber includes a test chamber body, several material trays, and several samples coated with powder coating. Support frames are fixedly connected to the inner walls of the left and right sides of the simulated chamber of the test chamber body. Several equally spaced rectangular slots are provided on the opposite side walls of the two support frames, and these rectangular slots are arranged horizontally opposite each other. The material trays are respectively inserted into the opposite rectangular slots. Each material tray has a material loading groove at its upper end, and a support structure is provided at the bottom of each material loading groove. The samples are all associated with the support structure.

[0007] Preferably, each pair of opposing rectangular slots has a strip-shaped arc protrusion on its inner wall, and each of the material trays has an arc-shaped slot on its left and right side walls. The inner walls of the front and rear sides of the arc-shaped slots are respectively connected to the front and rear side walls of the material trays. The strip-shaped arc protrusions are slidably inserted into the arc-shaped slots. Two handles are fixedly installed on the front side wall of each of the material trays.

[0008] Preferably, the strip-shaped arc protrusion and the support frame are integrally cast, and the material tray, the support frame and the strip-shaped arc protrusion are all wear-resistant alloy products.

[0009] Preferably, the support structure includes a plurality of conical limiting protrusions disposed on the bottom of the material loading trough, the plurality of conical limiting protrusions being distributed at equal intervals, the upper end of each of the plurality of conical limiting protrusions being provided with a strip-shaped slot, the plurality of strip-shaped slots on the same side being distributed at equal intervals, the bottom of the material loading trough near the front and rear sides of the plurality of conical limiting protrusions being provided with strip-shaped protrusions, and the plurality of sample pieces being placed on the inclined end face of the plurality of conical limiting protrusions or inserted into the plurality of strip-shaped slots.

[0010] Preferably, the left and right end sidewalls of the strip-shaped protrusion and the conical limiting protrusion are seamlessly connected to the left and right inner walls of the material loading groove, respectively, and the strip-shaped protrusion and the conical limiting protrusion are set with equal length.

[0011] Preferably, the conical limiting protrusion and the strip-shaped protrusion are integrally cast with the material carrier tray.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By inserting the material tray into the rectangular slots on both sides of the support frame, the strip-shaped arc protrusions in the rectangular slots slide into the arc slots, which facilitates quick positioning of the material tray, making operation convenient and preventing it from falling off easily.

[0014] 2.

Support frames 4 are fixedly connected to the inner walls of the left and right sides of the simulated chamber of the test chamber body 1. Several equally spaced rectangular slots 5 are provided on the opposite side walls of the two support frames 4, and the rectangular slots 5 are arranged horizontally opposite each other. Several material trays 2 are respectively inserted into the pairs of opposite rectangular slots 5. Each material tray 2 has a material loading groove 6 at its upper end. Strip-shaped arc-shaped protrusions 7 are provided on the opposite inner walls of the pairs of opposite rectangular slots 5. Arc-shaped slots 8 are provided on the left and right side walls of the several material trays 2. The front and rear inner walls of the several arc-shaped slots 8 are respectively connected to the front and rear side walls of the material trays 2. The design incorporates several strip-shaped arc-shaped protrusions 7 that are slidably inserted into several arc-shaped slots 8. Several material trays 2 are inserted into the test chamber body 1, with each material tray 2 positioned in a rectangular slot 5 on a pair of opposing support frames 4. The strip-shaped arc-shaped protrusions 7 in the rectangular slots 5 are slidably inserted into the arc-shaped slots 8 within the material trays 2. This design facilitates quick and easy positioning of the material trays 2 within the test chamber body 1, ensuring convenient operation while preventing easy detachment. Two handles 9 are fixedly installed on the front sidewalls of each material tray 2, allowing for easy pulling of the material tray 2 between the two support frames 4. The strip-shaped arc-shaped protrusions 7 and the support frames 4 are integrally cast. The material trays 2, support frames 4, and strip-shaped arc-shaped protrusions 7 are all made of wear-resistant alloy.

[0023] Each dry material loading tank 6 has a support structure at its bottom. Several sample pieces 3 are associated with the support structure. The support structure includes several conical limiting protrusions 10 on the bottom of the loading tank 6. The conical limiting protrusions 10 are evenly spaced.

Both the conical limiting protrusion 10 and the strip-shaped protrusion 12 are integrally cast with the material loading tray 2. Several sample pieces 3 coated with powder coating are inserted into the material loading tank 6 on several material loading trays 2, so that some sample pieces 3 lean against several conical limiting protrusions 10 and abut against the strip-shaped protrusion 12 for limitation. Other sample pieces 3 are vertically inserted into the strip slots 11 on several conical limiting protrusions 10. The sample pieces 3 are quickly and effectively positioned and supported, so that the sample pieces 3 have sufficient contact with the simulated environment and improve the accuracy of the test.

[0024] In use, this invention involves inserting several material trays 2 into the test chamber body 1, such that the material trays 2 are respectively inserted into rectangular slots 5 on opposite support frames 4, and the strip-shaped arc-shaped protrusions 7 in the rectangular slots 5 slide into the arc-shaped slots 8 in the material trays 2, facilitating quick and easy positioning of the material trays 2 within the test chamber body 1. Pulling the handle 9 moves the material trays 2 along the rectangular slots 5 until the strip-shaped arc-shaped protrusions 7 separate from the arc-shaped slots 8. The separation process is convenient and prevents easy detachment. Several sample pieces 3 coated with powder coating are inserted into the material slots 6 on several material trays 2, so that some sample pieces 3 lean against several conical limiting protrusions 10 and are restrained by the strip protrusions 12.
