Description

Technical Field

[0001] The utility model relates to the technical field of bolt production, and particularly relates to a processing device for bolt surface spraying. Background Art

[0002] In the production and application process of bolts, anti-rust treatment is a key link to ensure their long-term stable operation and extend their service life. As an indispensable connecting part in mechanical equipment, bolts are often exposed to various adverse factors such as humidity, high temperature, and corrosive media in complex and changeable working environments. Prolonged use and environmental factors can cause the surface of bolts to rust, which not only increases the difficulty of disassembly and installation but also may lead to a decline in equipment performance or even failure, seriously affecting production efficiency and equipment safety. Surface painting technology has gradually become an important method for bolt anti-rust treatment. Through spraying a uniform and dense coating on the surface of bolts, the painting technology can effectively isolate the contact between bolts and corrosive media, thus playing an anti-rust role.

[0003] When some existing bolt spraying devices are in use, due to the limitations of certain structural designs, operators often face many inconveniences when placing and removing bolts.

[0004] For example, a surface spraying device for a bolt anti-rust process disclosed in the patent with the publication number CN213051234U. The spraying device of this patent fixes bolts conveniently by setting structures such as a box body, a partition board, a placing plate, a spring, a movable plate, a movable rod, a pressing plate, a paint spraying pipe, a first nozzle, and a conveying pipe, and then sprays paint on them through the first nozzle. The painting process is carried out inside the box body to reduce the volatilization of paint and ensure the health of operators.

[0005] The spraying device of this patent has many advantages, such as improving the painting efficiency, reducing the workload of operators, and reducing the volatilization of paint. However, there are still some potential problems, especially the inconvenience when placing bolts on the placing plate.

This design makes it necessary for operators to reach into the box body to operate when placing and removing bolts on the relatively distant placing plate, which is not only inconvenient to operate but also may affect the safety of operators.

[0006] Therefore, it is necessary to invent a processing device for bolt surface spraying to solve the above problems. Utility Model Content
