Description
- The present invention relates to a sandpaper-replacing device, particularly to a fast-perforated sandpaper-replacing device, whereby a grinder can be fast aligned to and stuck onto a perforated sandpaper.
- For a conventional grinder with autonomous dust suction function, refer to a R.O.C. patent of Publication No. 339717, which proposed “Grinding Device with Autonomous Dust Suction Function”. The conventional device comprises: a body, a cover, an intake pipe, an exhaust pipe, and dust-suck pipe. The body has a pneumatic motor, and the pneumatic motor is coupled to a grinding disc with multiple dust-suck holes, a perforated sandpaper is attached to the grinding disc. The cover surrounds the rim of the grinding disc and has an opening used to exhaust the dust generated in the grinding operation. The intake pipe is installed on the surface of the body and connected with a compressed-air pipe, and the compressed-air pipe is connected with an air compressor; the intake pipe transfers the compressed air to drive the pneumatic motor. The exhaust pipe is installed on the surface of the body and near the intake pipe; the exhaust pipe has an outlet to exhaust the used compressed air. The dust-suck pipe has a sucking end connected to the abovementioned opening of the cover and an exhausting end connected to a vacuum sucker. Thereby, the dust generated in the grinding operation can be sucked away lest the dust harm the operator.
- However, in practical operation, it is hard to exactly integrate the perforated sandpaper with the grinding disc of the grinder. Refer to
FIG. 1 a diagram showing that a perforated sandpaper is being attached to a grinding disc. As shown inFIG. 1 , thegrinding disc 2 of agrinder 1 has multiple dust-suck holes 3, and a perforatedsandpaper 10 is attached to thegrinding disc 2 with a hook and loop fastener. The perforatedsandpaper 10 has multiple through-holes 11 arranged corresponding to the dust-suck holes 3. When the user is to attach a newperforated sandpaper 10 to thegrinding disc 2, he has to accurately align theperforated sandpaper 10 to thegrinding disc 2 so that the dust-suckholes 3 of thegrinding disc 2 can exactly coincide with the through-holes 11 of theperforated sandpaper 10. Thus, the dust-suck function of thegrinder 1 can perform normally. FromFIG. 1 , it can be observed: it is very hard to make all the through-holes 11 coincide with all the corresponding dust-suck holes 3. Even though the operator has carefully aligned theperforated sandpaper 10 to thegrinding disc 2, the mismatch between the through-holes 11 and the dust-suck holes 3 still occurs after theperforated sandpaper 10 has been attached to thegrinding disc 2. Thus, theperforated sandpaper 10 will be peeled off from and reattached to thegrinding disc 2. It may needs many times reattachments to successfully make the through-holes 11 coincide with the dust-suck holes 3. Therefore, the conventional technology not only obviously inconveniences the user but also greatly reduces the working efficiency. - The primary objective of the present invention is to provide a fast-perforated sandpaper-replacing device, which can meet the industry standards of perforated sandpapers, promote the convenience of perforated sandpaper application and solve the conventional problems mentioned above.□
- Another objective of the present invention is to provide a fast-perforated sandpaper-replacing device, wherein the fast-perforated sandpaper-replacing device of the present invention has an aligner; a grinder can be precisely aligned to the fast-perforated sandpaper-replacing device with the aligner, and then, the grinder is pressed against a perforated sandpaper alignment device and precisely attached to the perforated sandpaper put on the alignment device; thereby, the efficiency of replacing perforated sandpapers can be greatly promoted.
- The present invention proposes a fast-perforated sandpaper-replacing device, which comprises a casing. The casing has a through-hole, an aligner installed in its surface, and a movable member installed thereinside. An elastic element is arranged between the movable member and the bottom of the casing. A perforated sandpaper alignment device is coupled to the movable member. A grinder is aligned to the fast-perforated sandpaper-replacing device with the aligner. When pressed by a force, the grinder further presses down the movable member and the elastic element and moves toward the perforated sandpapers accommodated by the alignment device. Thus, the grinding disc of the grinder can precisely stick onto the topmost perforated sandpaper.

After the alignment is done, the user presses thegrinder 1 down; thepositioning seat 50 is pushed down and further presses down themovable member 30 and theelastic element 40, and thegrinder 1 is displaced toward theperforated sandpapers 10. Thus, as shown inFIG. 4B , the positioningseat 50 recedes into thecasing 20 via the through-hole 23, and thegrinding disc 2 contacts the topmostperforated sandpaper 10, and the dust-suck holes 3 of thegrinding disc 2 exactly coincides with the through-holes 11 of theperforated sandpaper 10. Thus, theperforated sandpaper 10 is securely stuck onto thegrinding disc 2 via a hook and loop fastener, and the user can utilize thegrinder 1 to perform a grinding work. As shown inFIG. 4C , after thegrinder 1 has been lifted from the positioningseat 50, theelastic element 40 restores themovable member 30 and thepositioning seat 50 back to the original position. As the limitingslot 31 and the limitingrib 24, which are arranged corresponding to each other, are respectively formed on themovable member 30 and the inner wall of thecasing 20, themovable member 30 and thepositioning seat 50 can only move in the vertical direction, and the alignment relationship between thegrinding disc 2 and theperforated sandpaper 10 will not deviated during the movement of themovable member 30 and thepositioning seat 50. Besides, thecasing 20 has atleast air vent 25. When themovable member 30 is moved downward or upward, the air can rapidly flow through theair vent 25 to balance the air pressure lest the movement of themovable member 30 be retarded. - In the present invention, the user can align the
grinder 1 to theperforated sandpaper 10 with thealigner 22 on thecasing 20; then, the user presses down thegrinder 1 to precisely stick onto theperforated sandpaper 10 on thepositioning seat 50; thereby, the dust-suck holes 3 of thegrinding disc 2 can fast and exactly coincide with the through-holes 11 of theperforated sandpaper 10. Therefore, the present invention can greatly simplify the procedures of attaching theperforated sandpaper 10 to thegrinder 1. It is to be noted that thepositioning seat 50 is not installed to themovable member 30 fixedly. When the perforated sandpapers 5 are used up, the positioningseat 50 can be pulled out from the through-hole 23, and new perforated sandpapers 10 can be easily resupplied to thepositioning seat 50. Further, the perforated sandpapers 10 may be stacked ontomultiple positioning seats 50 beforehand. Once the perforated sandpapers 10 are used up in onepositioning seat 50, thespare positioning seat 50 with new perforated sandpapers 10 can instantly replace theempty positioning seat 50. Furthermore, the numbers, sizes and positions of the fixingpoles 51 of the positioning seats 50 may vary to meet different perforated sandpapers in the market. Up to now, the characteristics of the present invention-simple and precise attachment of the perforated sandpaper onto the grinder, and fast resupply of the perforated sandpapers via the positioning seat-has not appeared in the related products in the market or been applied to the field concerned. - Those described above are only the preferred embodiments to clarify the present invention.
