AI Technical Summary

Technical Problem

Existing coating production lines have difficulty controlling powder concentration in the powder spraying chamber, leading to safety hazards such as flammability and explosion, or problems with uneven coating thickness.

Method used

By installing a storage bin, dust concentration sensor, and material guiding assembly in the powder spraying chamber, and using a self-locking motor and stepper motor to adjust the angle and position of the discharge hopper, combined with a blower to control the powder concentration, dynamic adjustment of powder concentration can be achieved.

Benefits of technology

Effectively control the powder concentration in the powder spraying chamber avoids safety hazards, ensures uniform coating thickness, and improves the safety and efficiency of the production line.

Abstract

The utility model discloses an intelligent production line for coating tower crane structural parts, and particularly relates to the technical field of coating of tower crane structural parts. A workpiece feeding station, a shot blasting chamber, a pretreatment chamber, a water blowing chamber, a moisture drying chamber, a water purification unit, a zinc spraying chamber, a powder spraying chamber, an infrared preheating chamber, a curing chamber, a forced cooling chamber, a central control chamber and a workpiece discharging station are sequentially arranged on the power and free chain, a storage box is movably arranged in the powder spraying chamber, and connecting plates are fixedly connected to the positions, close to the edges of the two sides, of the bottom end of the storage box. Powder is sprayed to the tower crane structure through the discharging hopper, the stepping motor works to drive the discharging hopper and the dust concentration sensor to horizontally move, when the dust concentration sensor detects too high powder concentration, the exhaust fan works to generate suction force, and powder in the powder spraying chamber enters the air pipe through the discharging hopper; therefore, the powder concentration in the powder spraying chamber can be reduced, operation is easy, and the powder concentration in the powder spraying chamber can be changed conveniently.
