Automatic casting coating spraying device

Abstract

The invention relates to the technical field of spraying devices, in particular to an automatic casting coating spraying device which comprises a base, wherein a mixing device is arranged on one sideof a work box; a feeding device is arranged in a feeding hole; a guide plate is obliquely arranged in a discharging hole; two fluted discs are rotatably connected with the interior of a through groove; fixed devices are symmetrically arranged between the two fluted discs; a lead screw is rotatably connected between the lower parts of two partition boards through a bearing pedestal; a sliding seatis in screw joint with the outer side of the lead screw; a spraying mechanism is arranged at the upper end of the sliding seat; and the output shaft of a second motor penetrates through the partitionboards to be fixedly connected with the lead screw. The automatic casting coating spraying device is reasonable in structural design and convenient and fast to use, can mix coating uniformly and avoids sedimentation, ensures the casting spraying effect and also carries out air drying treatment on the castings to greatly improve the working efficiency and lower the labor intensity of a worker, hashigh practicality and deserves popularization.

Description

technical field [0001] The invention relates to the technical field of spraying devices, in particular to an automatic coating device for casting paint. Background technique [0002] At present, brushing paint is the main means to obtain good surface quality of castings. Commonly used paint application methods include spraying, brushing, dipping, etc. Spraying is often used for local application, which requires high paint quality and spraying equipment; brushing It is simple and easy to use and has a wide range of applications, but the interface quality of the coating is poor and it is the most difficult to control; dip coating is suitable for the outer surface of the inner core, and the quality is good. When it is used for the shell core, a large number of places that do not need coating are also coated, resulting in waste.

[0002] At present, brushing paint is the main means to obtain good surface quality of castings. Commonly used paint application methods include spraying, brushing, dipping, etc. Spraying is often used for local application, which requires high paint quality and spraying equipment; brushing It is simple and easy to use and has a wide range of applications, but the interface quality of the coating is poor and it is the most difficult to control; dip coating is suitable for the outer surface of the inner core, and the quality is good. When it is used for the shell core, a large number of places that do not need coating are also coated, resulting in waste

[0003] The existing paint spraying method is usually to manually spray the paint on the surface of the casting with a spray gun. Due to the different operating levels of the workers, there will be uneven spraying, which will cause color difference on the surface of the casting and reduce the quality of the product. It will spread out and cause damage to the worker's body. In addition, the paint will precipitate and adhere to the barrel wall in the paint bucket, resulting in a decline in the quality of the paint, which will affect the spraying effect of the paint and is inconvenient to use.
