Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying equipment, in particular to a drying device. Background Art
[0002] After surface treatments such as electroplating, phosphating, oxidation and other conversion coatings in water-related operations, hot air is generally required for water removal. After water removal by hot air, the workpiece is in an environment with high temperature and high water vapor partial pressure. The workpiece after surface treatment needs to be cooled and dried before it can be sealed. Sealing without cooling and drying will cause too high relative humidity in the package, resulting in phenomena such as discoloration and flash rust of the workpiece. Therefore, after water removal, the existing workpieces are usually placed in a drying oven for drying before they can be sealed.
[0003] However, the existing drying ovens all have an openable and closable hatch. However, during the process of batch placing of workpieces into the drying oven, the hatch is always in a fully open state and will not be closed for drying until all the workpieces are placed. This causes the workpieces placed in the drying oven first to be continuously exposed to the air and cannot be dried in time. The humid air is likely to corrode the surface of the workpiece, resulting in poor phenomena such as discoloration and rust on the surface of the workpiece. Summary of the Invention
[0004] Aiming at the above deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a drying device, which is used to solve the problems in the prior art that the hatch cannot be closed for drying until all the workpieces are placed, resulting in the workpieces placed first being exposed to the air for a long time, causing discoloration and rust.

[0024] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.
[0025] Please refer to Figures 1-3 , the present utility model discloses a drying device, including:
[0026] A box body 100, the box body 100 is provided with a plurality of placement trays 300 for placing workpieces along its height direction, and a pick-and-place opening is provided on the side of the box body 100;
[0027] The hatch door 200 is provided on the side of the box body 100 and can slide relative to the box body 100 in the height direction to close or open the access opening. During the process of picking and placing workpieces, the hatch door 200 can slide to cover the height of all workpieces.
[0028] In this application, the hatch door 200 is set to be slidable in the height direction, and the placement trays 300 in the box body 100 are also arranged in the height direction, so that the hatch door 200 can slide along with the placement height of the workpieces to cover all the placed workpieces in time, so that the drying and cooling device in the box body 100 can cool and dry the workpieces in time. After all, the workpieces placed first wait for a long time, resulting in bad phenomena such as discoloration and rust on the surface of the workpieces.
[0029] Specifically, first lift the hatch door 200 upward to fully open the access opening, and then place the workpieces on the placement trays 300 one by one from top to bottom. During this process, the hatch door 200 also slides from top to bottom. After the workpiece is placed on the placement tray 300 at the current height, the hatch door 200 slides downward a certain distance to cover the just-placed workpiece, continue to place the workpiece on the placement tray 300 at the next height and lower the hatch door 200 to cover it. Until all the placement trays 300 are filled with workpieces, the hatch door 200 slides downward to be fully closed.
[0030] Further, a slide rail 140 is provided on the side of the box body 100 in the height direction, and the hatch door 200 is slidably arranged on the slide rail 140.
[0031] Further, a slidable limit block 400 is provided below each placement tray 300, and the limit block 400 can extend horizontally and abut against the bottom of the hatch door 200.
[0032] Specifically, when placing the workpiece on the placement tray 300 at the current height, the hatch door 200 is limited on the limit block 400 at the previous height and cannot continue to slide downward; when the workpiece is placed on the placement tray 300 at this height, the limit block 400 at the previous height retracts, and the hatch door 200 descends a certain distance and abuts against the limit block 400 below the current placement tray 300 to realize the limit of the hatch door 200. Until all the workpieces are placed, the hatch door 200 descends to fully close the access opening.
[0033] Further, a sliding seat 410 is provided below the placement tray 300, and the limit block 400 is slidably arranged on the sliding seat 410.
