AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve uniform thickness of putty filling at irregular curved grooves in particleboard, resulting in high drying shrinkage and uneven thickness of water-based putty, which easily leads to coating cracking and makes it difficult to meet the quality stability requirements of large-scale production.

Method used

A device for processing curved surfaces of particleboard drawers based on an environmentally friendly coating system was designed. The device includes a worktable, a fixed fixture, and a movable hanger. By using a horizontal scraper and a side scraper in conjunction with a putty extrusion unit, along with a distance sensor and a linear actuator, the device achieves precise filling and thickness control of putty on the particleboard surface.

Benefits of technology

It achieves complete sealing of irregular grooves in particleboard, avoids uneven putty thickness, ensures uniform and dense putty layer, reduces material waste and rework rate, and provides a smooth base for subsequent coating processes.

Abstract

The invention relates to the technical field of plate processing, in particular to a shaving board drawer curved surface closed processing device based on an environment-friendly coating system.The shaving board drawer curved surface closed processing device comprises a workbench, a fixed clamp and a movable hanging bracket, and the movable hanging bracket moves in the length direction of a shaving board clamped by the fixed clamp; a lifting seat capable of vertically lifting is arranged at the top of the movable hanging bracket, a horizontal scraping plate and a side scraping plate are arranged on one side of the lifting seat, and the lifting seat lifts in the vertical direction in the moving process of the movable hanging bracket to keep the gap between the horizontal scraping plate and the top of the shaving board consistent; according to the technical scheme, putty is continuously and quantitatively extruded to the surface of the shaving board through the putty extrusion unit, the flowing range of the putty is effectively restrained through cooperation of the horizontal scraping plate and the side scraping plate, and the thickness of a filling layer is accurately controlled through dynamic lifting adjustment of the lifting base; the problem that the thickness of putty is not uniform due to a special-shaped curved surface is solved while the special-shaped notch of the shaving board is comprehensively sealed, and the situation that a concave area is insufficient in filling or accumulation at a convex position is too thick is effectively avoided.
