Description

Technical Field

[0001] This utility model relates to the field of air drying, and more specifically, to an air dryer for spraying coatings on gears and cutting tools. Background Technology

[0002] PVD coating technology is a green and clean surface treatment technology—a coating of hundreds of nanometers to tens of micrometers is prepared on the surface of a target workpiece using physical methods in a high vacuum. It can provide specific surface hardening requirements. Since PVD coating can strengthen the surface strength of cutting tools and thus improve their service life, it is also widely sprayed on the surface of various cutting tools. During the spraying process, the cutting tool needs to be clamped and locked by a clamping device.

[0003] The utility model patent with authorization announcement number CN 221694025 U discloses a drying device for spraying coatings on cutting tools, including a support base, a rapid drying component, and an adjustment component. The beneficial effects of this utility model are: when spraying coating material onto a cutting tool, the tool is first fixed using a clamping head, and then the external spraying device is used to spray the coating material onto the tool. After spraying, the first motor can be turned on, causing the fan blades to rotate, generating airflow that blows onto the tool through the air outlet, thus drying the coating material on the tool surface. During use, by starting the second motor, the second motor drives the rotating rod to rotate, which in turn drives the gear to rotate. The gear rotation, through meshing, causes the gear plate to move up and down on the track surface, thereby adjusting the height of the fan blades and facilitating the drying of coatings at different heights on the tool surface.

[0004] In the above-disclosed structure, the drying component and the adjustment component are installed on the support base to clamp the tool for drying. However, the positioning cylinder connected to the rotating plate is not used for support and positioning, so it cannot be rotated and adjusted to ensure the uniformity of the air blowing. In addition, the adjustment cylinder installed on the fixed cylinder is not used for positioning and adjustment, so it cannot be sealed and protected. The sprayed material is blown away and causes pollution. The safety and stability are poor and need to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an air dryer for spraying coatings on gear cutting tools. A motor is installed on the mounting bracket on the filter box, which connects to the rotating plate and the positioning cylinder. The rotating adjustment can be adjusted after positioning the cutting tool, which is conducive to uniform air drying. Furthermore, the fan and the adjusting cylinder are installed on the fixed cylinder, which can slide to adjust the position to avoid interference. The air can be sealed and protected during blowing, which is conducive to circulation filtration, improves the safety of use, and is conducive to combined use.
