One side of the base 1 has a polishing blade 3 moving along the edge of the base 1. The polishing blade 3 thus polishes a surfacc of the acrylic object 2 on the base 1.

[00031 However, one has to be manually adjusted the position of the acrylic object 2 on the base 1 in the conventional acrylic polisher before polishing. The surface 4 of the acrylic object 2 to be polished slightly protrudes from the end surface of the base 1. Afterwards, the user controls the distance between the acrylic object 2 and the polishing blade 3 by eyes, thereby determining the polishing depth of the polishing blade 3 on the acrylic object 2. However, the above-mentioned method of controlling the distance between the acrylic object 2 and the polishing blade 3 by eyes is not only time-consuming, but also has a larger errors in the distance and the level.

DETAILED DESCRIPTION OF THE INVENTION [0022) The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

[0023] Please refer to FIGS. 1 to 3. The acrylic polisher that can reserve a machining buffer space according to the invention has 2L base 11, a cuffing blade set 2 1, a conveyor 3 1, and a stopping board 4 1.

[0024] The base 11 has two oppositely disposed sideboards 12 with a disposition surface 13 in between for the placement of an acrylic object 10. Each of the two sideboards 12 has a track 14 and a notch 15. The tracks 14 and notches 15 of the two sidcboards 12 axe opposite to each other, respectively. The notches 15 on the two sideboards 12 form an open space 16 on both sides of the disposition surface 13.

One of the sideboards 12 has a control panel 17.

100251 The cuffing blade set 21 has a horizontal track 22 and a cutting blade 2$.

The horizontal track 22 is fonned on the front side of the disposition surface 13 of the base 11. The cutting blade set 23 is disposed on the horizontal track 22 to perform a 4 COMS ID No: ARCS-218420 Received by IP Australia: Time (I-tm) 13:23 Date 2008-12-24 24/12/2008 13:57 24/2/0091357 6444965949 EVT LAW PG 92 PAGE 09/24 00 0) o) horizontal displacement toward the edge of the disposition surface 13 along the o horizontal track 22. The cutting process is performed between a starting point 24 0 and an ending point 25, a5 shown in FIG. 6.

[00261 The conveyor 31 is disposed above the disposition surface 13, between the two sideboards 12. A driving device 32 (an air-pressured cylinder structure in this Cl embodiment) is provided on the conveyor 31. One side of the conveyor 311is futher 0 provided with several air-pressured cylinders 33, each of which is connected wit a 00 O pressing element 331. The pressing elements 331 can press and position the acrylic Cl object 10 disposed on the disposition surface 13.

10027] The stopping board 41 is disposed in the conveyor 31 on the two sideboards 12. The stopping board 41 has roughly a UI shape. Both sides are formed wit a guiding track 42, respectively- The end surface of the stopping board 41 facing the acrylic object 10 has a stopping surface 43. The stopping board 41 is embedded by the guiding tracks 42 on its two sides in the tracks 14 of the two sideboards 12. The stopping board 41 is connected with the driving device 32, and driven by it to move up and downs along the tracks 14 of the two sideboards 12 and relative to the disposition surface 13 of the base 11. When the stopping board 41 moves downward to the side of the disposition surface 13, a predetermined machining spn44i formed between the stopping surface 43 of the stopping board 41 and the disposition surface 13 of the base 11. A protruding part 45 is formed ont the stopping surface 43 near the starting point 24 of the cutting blade set 21. In this embodiment, the stopping surface 43 of the stopping board 41 is formed with an embedding groove 451, screwed with a protruding block 452. The protruding block 452 slightly protrudes from the stopping surface 43 to become the protruding part [0028] In practice, as shown in FIG. 2, the invention first uses the driving, device 32 COMS ID No: ARCS-218420 Received by IP Australia: Time 13:23 Date 2008-12-24 24/12/2008 13:57 6444965949 MITr ALl PAGE 10/24 00 oto move the stopping board 41 1downward along the two tracks 14 to the side of the disposition surface 13 of the base 11. The machining span 44 is formed between the 0 stopping surface 43 of the stopping board 41 and the disposition surface 13 at this Cl moment. Therefore, the user only needs to directly put the acrylic object 10 on the disposition surface 13 of the base I1I and push it toward the stopping surface 43 of the stopping board 41. The stopping surface 43 of the stopping board 41 provides the 2 surface of the acrylic object 10 to be polished with a guide and restricts the cutting 0S depth on the acrylic object 10. Therefore, without additional measurements, the user ci can readily obtain a highly precise machining span 44. The invention can fuirther fix the machining span 44 of the acrylic object 10 each time. Afterwards, as shown in FIG. 3, when the stopping board 41 rises, the air-pressured cylinders 33 lower the pressing clements 331 to press against the acrylic object 10 for fixing it. This make subsequent polishing of the acrylic object 10 by the cutting blade set more convenient.

[0029] Moreover, when the stopping board lowers to the side of the disposition surface 13 of the base 11, the guiding tracks 42 oni both sides of the stopping board 41 are embedded in the tracks 14 of the two sideboards 12. Therefore, even if the user pushes the acrylic object 10 with a larger force so that there is a collision with the stopping surface 43 of the stopping board 41, the design of the guiding tracks 42 and the tracks 14 provides the stopping board 41 with a better supporting strength against the horizontal stress. It fur-ther ensures that the machining span 44 betweeni the stopping surface 43 of the stopping board 41 and the disposition surface 13 is kept fixed, instead of having errors due to the collision of the acrylic object [0030j As shown in FIG. 4, the invention uses the notches 15 on the two sideboards 12 to form an opening space on the left, tight, and rear sides of the disposition surface 13 of the bas 11. Therefore, even if the length of the acrylic object 10 is larger than 6 COMS ID No: ARCS-218420 Received by IP Australia: Time (I-Pm) 13:23 Date 2008-12-24 24/12/2008 13:57 24/2/00213576444965949 EVT LAW PG 12 PAGE 11/24 00 o the length of the disposition surface 13 of the base 11, the operator can conveniently dispose the acrylic object 10 on the disposition surface 13 through the opening space.

0 As shown in FIG. 5, the operator only needs to adjust the position of the acrylic objcct 1to complete the polishing job of the acrylic object 10 without additional cutting.

[0031J Please refer to FIG. 6. When the invention polisbes a larger acrylic object in several steps, the acrylic object 10 is directly disposed on the disposition surface 13 0 of the base 11. The user then pushes it toward the stopping surface 43 of the 00 stopping board 41 for first polishing. After that, the operator adjusts the position of the acrylic object 10 so that the unpolished end surface 101 thereof is located in the cutting stroke of the cutting blade 23. After-wards, the stopping board 41 is lowered to push the acrylic object 10 toward the stopping surface 43 of the stopping board 41.

As shown in FIG. 7, the operator urges the acrylic object 10 against the protruding part 45 of the stopping surface 43. A reserved machining buffer space 46 formed between the acrylic object 10 and the stopping surface 43.

[0032] As shown in FIG. 8, when the cutting blade 23 performs the second polishing, it does not directly touch the acrylic object 10 due to the machining buffer space 46.

The machining buffer space 46 elongates the contact time between the cutting blade 23 and the acrylic object 10. The rotation speed of the cutting blade 23 can achieve a predetermined value, effectively avoiding scratches on the surface of the acrylic object 10 during the second polishing. The invention th-us has 'very good surface yields.
