Description

Technical Field

[0001] The utility model relates to the technical field of vacuum drying ovens, in particular to a vacuum drying oven for laser absorbents. Background Art

[0002] During laser processing, it is necessary to use laser absorbers for targeted absorption and to protect the human body and workpieces. Laser absorbers need to be dried. The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposable and easily oxidized substances. It can maintain a certain vacuum degree in the working room during operation and can fill the interior with inert gas, especially some items with complex ingredients can be dried quickly. An intelligent digital temperature regulator is used to set, display and control the temperature.

[0003] For example, a vacuum drying oven with authorization announcement number CN204787606U has a detachable tray, which is convenient for drying items of different sizes and cleaning the tray. It intelligently controls the operation of the heating tube, refrigerator and exhaust device, reduces manpower and saves time. The vacuum drying oven mentioned above adopts the method of placing the powder items to be dried in the tray and then putting them into the vacuum drying oven for drying. Then, the laser absorbent powder piled on the tray is inconveniently fixed in the vacuum drying oven. However, when the laser absorbent powder is piled, there will be a certain difference in the thickness of the powder, which will make the drying rate and results uneven, so that some parts of the powder after drying in the vacuum drying oven are dried more thoroughly, while some parts of the powder are dried poorly, which affects the working effect of the vacuum drying oven.

[0004] At the same time, in the existing vacuum drying box, since the tray is directly inserted into the interior of the vacuum drying box, the operator needs to open the door of the drying box when taking it out, and then pull out the tray with an area close to the drying box to achieve cleaning and maintenance. When pulling out the tray, the operator's hands need to be occupied, which is more laborious to use, and the powder placed on the tray is easy to spill when taking it out, which will cause waste of materials dried by the laser absorber and affect the convenience of use of the vacuum drying box. Summary of the invention

[0005] The utility model aims to solve the problems existing in the prior art and provide a vacuum drying box for laser absorbent, so as to achieve better working effect and more convenient use.

After closing the outer sealing door, connect the power supply to start the motor at the top. The motor output shaft will drive the first gear at the lower end to rotate. When the first gear rotates, it will drive the second gear to rotate through the meshing saw teeth.

After closing the outer sealing door 94, the power is connected to start the motor 41 at the top, and the output shaft of the motor 41 will drive the first gear 42 at the lower end to rotate, and the second gear 44 will rotate. When the first gear 42 rotates, it will drive the second gear 44 to rotate through the meshing serrations. Since the diameter of the first gear 42 is much smaller than that of the second gear 44, the motor 41 drives the first gear 42 to rotate multiple circles before the second gear 44 rotates one circle. In this way, the second gear 44 can drive the rotating column 45 at the bottom to rotate slowly inside the drying box body 1. The rotating column 45 will continuously drive the fixed position containing groove 55 and the inner laser absorbent powder to achieve a uniform drying effect. The bottom end of the second gear 44 is fixedly connected to the top end of the rotating column 45.

When the first gear 42 rotates, it will drive the second gear 44 to rotate through the meshing saw teeth. Since the diameter of the first gear 42 is much smaller than the diameter of the second gear 44, the motor 41 drives the first gear 42 to rotate multiple times before the second gear 44 rotates one circle. In this way, the second gear 44 can drive the rotating column 45 at the bottom to rotate slowly inside the drying box body 1. The rotating column 45 will continuously drive the holding tank 55 fixed in position and the laser absorbent powder inside to achieve a uniform drying effect.

After the position of the holding groove 55 is fixed, the clamping plate 63 is released, and the clamping plate 63 will squeeze the holding groove 55 and fix it under the elastic force of the tension spring 62, so that the holding groove 55 is not easy to loosen or fall off during the spin drying and taking process, and the hands of the operator can be freed. The clamping plate 63 is slidably connected to the top of the supporting plate 54, and a plurality of protrusions 64 are fixedly installed on the inner wall of the clamping plate 63. The protrusions 64 are made of a rubber sheet with a texture to increase the extrusion friction of the clamping plate 63, and the inner side of the clamping plate 63 is movably connected to the holding groove 55;

[0033] When fixing the containing groove 55, the clamping plate 63 is first manually pushed outward, and then the containing groove 55 is placed on the top of the support plate 54. The clamping plate 63 will pull the tension spring 62 to stretch the tension spring 62 to accumulate kinetic energy. After the position of the containing groove 55 on the tray 54 is fixed, the clamping plate 63 is released.

[0036] Working principle:

[0037] In the process of vacuum drying the laser absorbent powder using a vacuum drying oven:

[0038] Uniform rotary drying structure of vacuum drying oven for laser absorbent:

[0039] When the laser absorbent needs to be dried, the laser absorbent powder is first poured into the prepared holding tank 55, and then the holding tank 55 is fixed above the tray 54. After the outer sealing door 94 is closed, the power is connected to start the motor 41 at the top. The output shaft of the motor 41 drives the first gear 42 at the lower end to rotate. When the first gear 42 rotates, it drives the second gear 44 to rotate through the meshing saw teeth. Since the diameter of the first gear 42 is much smaller than that of the second gear 44, the motor 41 drives the first gear 42 to rotate multiple times before the second gear 44 rotates one circle. In this way, the second gear 44 can drive the rotating column 45 at the bottom to rotate slowly inside the drying box body 1. The rotating column 45 will continuously drive the holding tank 55 fixed in position and the laser absorbent powder inside to achieve a uniform drying effect.

[0040] Laser absorbent is vacuum dried in a vacuum drying oven to manufacture the structure:

The sealed door 94 can be opened at any time through the hinge. After the laser absorbent is placed inside the drying chamber 51, the labyrinth door 94 is closed, and the power supply is connected to start the vacuum pump 93. The vacuum pump 93 will suck the air inside the drying chamber 5 along the exhaust pipe 92 to create a vacuum environment inside the drying chamber 51. The one-way valve 92 can make the air exhausted and unable to return to the drying box body 1.

[0042] Laser absorbent vacuum drying oven containing tank clamping and fixing structure:

[0043] When fixing the receiving slot 55, the clamping plate 63 is first manually pushed outward, and then the receiving slot 55 is placed on top of the support plate 54. The clamping plate 63 will pull the tension spring 62 to lengthen the tension spring 62 to accumulate kinetic energy. After the position of the receiving slot 55 is fixed on the tray 54, the clamping plate 63 is released. The clamping plate 63 will squeeze the receiving slot 55 and fix it under the elastic force of the tension spring 62. In this way, the receiving slot 55 is not easy to loosen or fall off during the rotary drying and taking process, and the operator's hands can be freed.
