Problems solved by technology

However, in the actual production process, we found that when the veneer is polished, the grinding wheel accelerates the wear of the grinding wheel due to the presence of impurities on the surface of the veneer, and the surface of the veneer is damaged during the grinding, and the paint is on the surface. The coating is uneven, and the surface of the thin plate after coating is uneven, which affects the surface quality of the thin plate; the surface flatness of the template that needs to be painted sometimes may not meet the requirements, and the surface of the thin plate will also be uneven after painting , poor paint effect

Abstract

The invention discloses a veneer pretreatment device. The veneer pretreatment device is characterized in that a veneer conveying roll, preliminary grinding rolls and an impurity removing mechanism are included; the three preliminary grinding rolls comprise the first preliminary grinding roll, the second preliminary grinding roll and the third preliminary grinding roll, the mounting height of the first preliminary grinding roll is smaller than that of the second preliminary grinding roll, the mounting height of the second preliminary grinding roll is equal to that of the third preliminary grinding roll, and the veneer conveying roll, the first preliminary grinding roll, the second preliminary grinding roll, the third preliminary grinding roll and the impurity removing mechanism are sequentially arranged in the veneer running direction. The device is used for carrying out pretreatment and polishing treatment on the veneer in sequence, after the device carries out pretreatment, in the polishing process, abrasion to a polishing wheel is greatly reduced, the surface evenness of the veneer is greatly improved, and the good varnishing effect is obtained.

Description

technical field [0001] The invention relates to a device used in veneer production, in particular to a device for surface pretreatment before polishing the veneer. Background technique [0002] Wood veneer (commonly known as: veneer, veneer; English: veneer; hereinafter collectively referred to as veneer) and its veneer decoration industry started in the 1950s, and after half a century of development, it has already possessed a considerable scale. Especially in the past two decades, with the rapid growth of my country's furniture manufacturing and decoration industries, its development has advanced by leaps and bounds, and a large number of industry experts have emerged. [0003] Typically, natural veneer is processed by planing. The process flow is as follows: logs→cutting→sectioning→softening (steaming or boiling)→slicing→drying (or not drying)→cutting→inspection and packaging→storage [0004] The following only introduces three important links: [0005] section [000...
