- The sand-belt finishing machine is a working machine that is used to finish the surface of the wooden material. A conventional sand-belt finishing machine in accordance with the prior art comprises a transverse roller, and a sand belt wound around the surface of the roller. When in use, the wooden material is passed through the lower side of the roller which is being rotated, so that the wooden material is rubbed and finished by the sand belt on the surface of the roller, thereby achieving a finishing effect. The powder chips attached on the surface of the sand belt need to be removed and cleared during a long-term utilization. In general, the sand belt is fixed on the sand-belt finishing machine, so that the user needs to use a tool, such as a brush, to clear the powder chips attached on the surface of the sand belt when the sand belt is being rotated, thereby causing inconvenience to the user, and thereby wasting the manual work. In addition, if the wooden material is passed through the lower side of the roller in an oblique or skew manner, a partial area of the surface of the wooden material is not finished by the sand belt, thereby decreasing the finishing effect.
- The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional sand-belt finishing machine.
- The primary objective of the present invention is to provide a sand-belt finishing machine having a reciprocal movement mechanism, wherein the eccentric unit produces a driving force to pull and push the first roller, so that the first roller is oscillated successively and produces a vibration or shock force on the sand belt, so as to remove and clear the powder chips attached on the surface of the sand belt.
- Another objective of the present invention is to provide a sand-belt finishing machine having a reciprocal movement mechanism, wherein the first roller is oscillated successively, so that the sand belt produces a transverse displacement so as to increase the contact area between the sand belt and the surface of the wooden material, thereby enhancing the finishing effect.
- In accordance with the present invention, there is provided a sand-belt finishing machine having a reciprocal movement mechanism, comprising:
- a main body;
- a swingable support rack mounted on the main body;

- FIG. 3 is a partially top plan enlarged view of the sand-belt finishing machine having a reciprocal movement mechanism as shown in FIG. 1;
- FIG. 4 is schematic top plan view of the sand-belt finishing machine having a reciprocal movement mechanism as shown in FIG. 1;
- FIG. 5 is a schematic operational view of the sand-belt finishing machine having a reciprocal movement mechanism as shown in FIG. 4 in use; and
- FIG. 6 is a schematic operational view of the sand-belt finishing machine having a reciprocal movement mechanism as shown in FIG. 5 in use.
- Referring to the drawings and initially to FIG. 1, a sand-belt finishing machine having a reciprocal movement mechanism in accordance with a preferred embodiment of the present invention comprises a
main body 10, afinishing device 20 mounted on themain body 10, and aneccentric device 30 mounted on themain body 10. Thefinishing device 20 includes afirst roller 22, asecond roller 24, and a sand belt 40 (see FIG. 4) mounted around thefirst roller 22 and thesecond roller 24. Thefirst roller 22 and thesecond roller 24 are in parallel with each other. Thefirst roller 22 is mounted on aswingable support rack 26 that is mounted on themain body 10. Thesand belt 40 having a loop shape is mounted on thefirst roller 22 and thesecond roller 24. - Referring to FIGS. 1 and 2, the
eccentric device 30 includes aneccentric unit 32, and apull lever 34. Theeccentric unit 32 of theeccentric device 30 is secured on thesupport rack 26. Thepull lever 34 of theeccentric device 30 has a first end connected to theeccentric unit 32 of theeccentric device 30, and a second end secured on themain body 10. - Referring to FIG. 3, the
eccentric unit 32 of theeccentric device 30 includes aworm 36, and aworm wheel 38 co-operating with theworm 36 so as to drive theeccentric unit 32 of theeccentric device 30. The first end of thepull lever 34 of theeccentric device 30 is eccentrically mounted on theworm wheel 38 of theeccentric unit 32 of theeccentric device 30. It is appreciated that, the power source for rotating thefirst roller 22 may be used to drive and rotate theeccentric unit 32 of theeccentric device 30. Thus, theworm 36 of theeccentric unit 32 of theeccentric device 30 is rotated by the power source of rotating thefirst roller 22, to rotate theworm wheel 38 of theeccentric unit 32 of theeccentric device 30, so as to move thepull lever 34 of theeccentric device 30. - Referring to FIG. 4, when the relative position between the
pull lever 34 of theeccentric device 30 and theworm wheel 38 of theeccentric unit 32 of theeccentric device 30 is as shown in FIG. 4, thefirst roller 22 is located at a horizontal state, and thesand belt 40 is located at the mediate position of thefirst roller 22. - Referring to FIG. 5, when the
worm wheel 38 is rotated and moved to the position as shown in FIG. 5, the first end of thepull lever 34 is eccentrically mounted on theworm wheel 38 of theeccentric unit 32 and the second end of thepull lever 34 is secured on themain body 10, so that theeccentric unit 32 is pulled by thepull lever 34 to move toward themain body 10, thereby driving thesupport rack 26 to swing and oscillate (because theeccentric unit 32 is secured on the support rack 26). Thus, thefirst roller 22 mounted on theswingable support rack 26 is oscillated with thesupport rack 26. - Referring to FIG. 6, when the
worm wheel 38 is rotated and moved to the position as shown in FIG. 6, theeccentric unit 32 is pushed by thepull lever 34 to move along the direction away from themain body 10, thereby driving thesupport rack 26 to swing and oscillate. Thus, thefirst roller 22 mounted on theswingable support rack 26 is oscillated with thesupport rack 26. - In conclusion, when the
finishing device 20 is operated, theeccentric device 30 is also operated synchronously, so as to drive thefirst roller 22 to oscillate and vibrate successively. Thus, thefirst roller 22 that is oscillated successively will produce a vibration or shock force on thesand belt 40, so as to remove and clear the powder chips attached on the surface of thesand belt 40, without having to stop operation of the sand-belt finishing machine for removing the powder chips, and without having to remove and clear the powder chips by a tool, such as a brush, thereby facilitating the user removing and clearing the powder chips, and thereby saving the manual work. - In addition, as shown in FIGS.4-6, when the
first roller 22 is oscillated successively, thefirst roller 22 applies a partial force to move thesand belt 40 in a transverse manner. Thus, the transverse displacement of thesand belt 40 increase the contact area between thesand belt 40 and the surface of the wooden material, thereby enhancing the finishing effect. - Accordingly, in the sand-belt finishing machine having a reciprocal movement mechanism in accordance with the preferred embodiment of the present invention, the
eccentric unit 32 may produce a driving force to pull and push thefirst roller 22, so that thefirst roller 22 is oscillated successively and produces a vibration or shock force on thesand belt 40, so as to remove and clear the powder chips attached on the surface of thesand belt 40. In addition, thefirst roller 22 is oscillated successively, so that thesand belt 40 produces a transverse displacement so as to increase the contact area between thesand belt 40 and the surface of the wooden material, thereby enhancing the finishing effect. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
