Sand-belt finishing machine having dust clearing function

Abstract

A sand-belt finishing machine includes two opposite grinding devices arranged in parallel with each other and each including two opposite rollers and a sand belt reeved around the two rollers, and a dust clearing device mounted between the two grinding devices. Thus, the wooden board is placed on a single main frame and is processed by a single working procedure to synchronously obtain a double surface treatment, including the rough working treatment and the finishing treatment, thereby greatly simplifying the working process.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a sand-belt finishing machine having a dust clearing function, and more particularly to a sand-belt finishing machine that is processed by a single working procedure to synchronously obtain a double surface treatment, including the rough working treatment and the finishing treatment, thereby simplifying the working process. [0003] 2. Description of the Related Art [0004] A conventional sand-belt finishing machine in accordance with the prior art shown in FIG. 1 comprises two rollers 12, a sand belt 14 reeved around the two rollers 12, and a dust clearing device including a hood 16 mounted outside of the two rollers 12 and the sand belt 14, and a suction member 18 mounted on the hood 16. Thus, the chips produced from the wooden board 50 during the grinding process can be introduced into the hood 16 by the suction effect of the suction member 18 and can then be drained outward.

AI Technical Summary

Benefits of technology

[0007] The present invention is to mitigate and / or obviate the disadvantage of the conventional sand-belt finishing machine.

[0008] The primary objective of the present invention is to provide a sand-belt finishing machine, wherein the wooden board is placed on a single main frame and is processed by a single working procedure to synchronously obtain a double surface treatment, including the rough working treatment and the finishing treatment, thereby simplifying the working process.

[0009] Another objective of the present invention is to provide a sand-belt finishing machine, wherein the dust clearing device is mounted between the two grinding devices to shorten the whole volume of the sand-belt finishing machine, thereby facilitating storage, package and transportation.

[0010] A further objective of the present invention is to provide a sand-belt finishing machine, wherein the chips produced from the wooden board can be introduced into the hood of the dust clearing device easily and conveniently.

[0011] A further objective of the present invention is to provide a sand-belt finishing machine, wherein the chips produced from the wooden board can be introduced into the hood of the dust clearing device rapidly without being attached on the surfaces of the sand belts of the two grinding devices, thereby enhancing the working quality of the wooden board.

[0012] A further objective of the present invention is to provide a sand-belt finishing machine, wherein the dust clearing device is mounted between the two grinding devices, thereby facilitating replacement and maintenance of the sand belts of the two grinding devices.

Problems solved by technology

In addition, the user needs to remove the hood 16 of the dust clearing device before replacing the sand belt 14, thereby causing inconvenience in replacement and maintenance.

Further, the sand belt 14 only has a single thickness, so that the user needs to replace the sand belts 14 of different thickness, thereby causing inconvenience in operation.

However, the above-mentioned problems still exist.
