Washed-out sand machine

Abstract

The invention discloses a washed-out sand machine, comprising a rack, a sanding belt cleaning renovating device and a cleaning agent recovery filtering device; wherein the rack is provided with a suspension shaft placing a sanding belt; the sanding belt cleaning renovating device is mainly composed of upper and lower rubber covered rollers for installing sanding belts, roller brush cleaning deviceand a power device driving all parts to operate, a sanding belt tension device is arranged between the upper and lower rubber covered rollers, and the roller brush device is internally provided witha roller brush cleaning core assembly matched with the lower rubber covered roller; the cleaning agent recovery filtering device is mainly composed of a filtering device, an ort scraper blade device provided with a high pressure exhaust device and a cleaning agent container, cleaning agent mixture with impurities in a cleaning machine is pumped into a wheel type filtering device by a circulating water pump, and the cleaning agent after flowing through the filtering device is pumped into the roller brush cleaning core assembly of the sanding belt cleaning renovating device by the circulating water pump. The invention can prolong the service life of sanding belt, saves expenditure cost about sanding belt and also avoids environmental pollution caused by abandoning massive waste sanding belts.

Description

technical field [0001] The invention relates to the technical field of woodworking equipment, in particular to a cleaning equipment for woodworking abrasive belts. Background technique [0002] At present, in the manufacturing process of the global woodworking industry, the sanding process is an indispensable process, especially the sanding of solid wood and related veneers, because solid wood and related wood products contain quite a lot of oil, wood glue, etc. The surface of the belt is prone to clogging of the sanding grain layer by these greases and jelly during the sanding process of the workpiece. Once the sanding particle layer is blocked, the sanding ability of the sanding belt will drop sharply, and whether the blocked place is local or large, it will have a negative impact on the sanding effect, resulting in blackening or blackening of the workpiece surface after sanding. Sanding is uneven. Usually an abrasive belt will be scrapped ahead of time for this reason a...

Problems solved by technology

Because of this loss, it adds a lot of cost to wood products companies every year, and the disposal of waste abrasive belts also causes serious pollution to the environment.

For this reason, it is necessary to recycle the abrasive belt, but there is no abrasive belt cleaning equipment developed for woodworking abrasive belts in the prior art, which can only rely on manual operation, and the cleaning cost is high; and in the process of cleaning the abrasive belt, it will produce A large amount of cleaning agent waste liquid mixed with impurities will not only fail to reduce costs, but will also cause serious pollution to the environment
