ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates to reciprocating-type abrasive device for a sanding machine, and in particular, to a sanding machine having a sanding module mounted with the reciprocating-type abrasive device at one end thereof such that the sanding particles can provide a tangent-like abrasive effect to a corresponding material to upgrade entire sanding effect thereof
(b) Description of the Prior Art
As wood material generally has relatively large amount of fibers, the surface thereof has to be treated in order to give a smooth surface so as to add value to the products formed from the material. Besides the treatment of the surface of the material internal holes of the wood material may also need treatment, and therefore an inner hole treating mechanism is supplemented to the sanding machine. Referring to
FIG. 1
, there is shown a conventional sanding machine having a machine body
10
mounted with a working platform
15
. One side of the platform
15
is provided with a sanding module
20
for the sanding of the surface of the wood material. The sanding module
20
has a support frame
21
with two ends respectively mounted with a driving roller
22
and a driven roller
23
. The driving roller
22
is connected to a motor
24
to drive a sanding belt (not shown) mounted around the driving roller
22
and the driven roller
23
. The inner hole sanding mechanism is mounted to the driving roller
22
by means of screw bolts
27
located on a shaft rod
26
having disposed with a sanding wheel
28
such that the sanding wheel
28
and the driving roller
22
rotate synchronously. That is, the rotation of the sanding wheel
28
is used to abrade the inner hole of the material.
However, the sanding wheel
28
of this conventional sanding machine provides a linear rotation, i.e., the position A on the sanding wheel
28
moves horizontally to the point A′. Thus, the material is polished in a linear manner. As the particles of the sanding wheel
28
contain very tiny gaps, the entire surface of the material cannot be polished. In other words, capillary holes on the surface of the material cannot be effectively removed. In addition, the entire surface will produce a “peak” or “valley” structure, and thus the surface of the material is rather rough. Additionally, the size of the material and the exertion force of the sanding wheel
28
on the material are not always constant, the exhaustion of particles of the sanding wheel
28
is not uniform. Thus, the surface of the sanding wheel
28
is irregular and the polished surface of the material will have similar irregularities, and the quality of the entire surface of the polished material is reduced. Therefore, it is an object of the present invention to provide a reciprocating-type abrasive device for a sanding machine, which can mitigate the drawbacks of the conventional sanding machine.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention is to provide reciprocating-type abrasive device for a sanding machine, wherein one end of the support frame of the sanding module is provided with a driving roller having a motor, and the other end of the support frame is mounted with the reciprocating-type abrasive device having a driven roller, and the driven roller corresponds to the driving roller and both surround a sanding belt, and the reciprocating-type abrasive device comprises a driving structure and a reciprocating structure, and the reciprocating structure is mounted with a sanding wheel which reciprocates up and down by the driving structure, thereby the sanding wheel produces a reciprocating abrasive action and the entire sanding effect is improved.
A further object of the present invention is to provide a reciprocating-type abrasive device for a sanding machine, wherein a reciprocating type sanding module is provided to the sanding machine, and a reciprocating rotational movement is produced by the sanding wheel so that the quality of the polished material is improved.
Other objects and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawing.
