Description

Highly abrasive polishing pad structure

The present invention relates to the technical field of a polishing pad, and more particularly to a polishing pad structure that can be coupled to a grinding machine and used as an abrasive element.

A common car waxing machine is a hand-held machine having one end locked to a grinding wheel, and one end of the grinding wheel has an abrasive surface for contacting a surface to be polished. Thus, when the grinding wheel is driven by the hand-held implement, the grinding surface of the grinding wheel can smooth the surface of the surface to be polished by rotating. Since the grinding wheel is coupled to the implement by means of a locking connection, the grinding wheel must be replaced by loosening the locking structure. In other words, the replacement of the grinding wheel is inconvenient.

Taiwan Patent No. M514901 discloses a polishing pad structure that is easy to replace. The technical feature is that a hook portion of the devil felt is disposed on one side of the polishing sheet, and the hook portion of the devil felt of the polishing sheet is combined with the buckle portion of the devil felt on the surface of the linkage of the grinder. In this way, the user can replace the abrasive sheet by tearing off.

Although the design of the prior patent is such that the replacement action of the polishing piece is simpler than that of the conventional grinding wheel, the polishing piece is a sheet structure, and the linking piece is a rigid disk body, so the polishing piece and the to-be-polished The surface, particularly the surface having curvature, is not easily formed into a conforming state, so the uniformity of the polishing and polishing of the surface to be polished of the abrasive sheet needs to be strengthened.

Secondly, the combination of the abrasive sheet and the linkage member has a rigid structure and is required for operation. In order to continuously adjust the grinding angle, the combination of the abrasive sheet and the linking member can be prevented from being excessively ground in the grinding surface, and thus the operation is inconvenient.

The present invention relates to a polishing pad structure having a high abrasive effect, which is capable of being more conformable to a surface to be polished, thereby providing a better polishing effect.

The invention relates to a polishing mat structure with high grinding effect, which has a combination form capable of utilizing a connection layer of a devil felt, so that the user can perform the replacement of the polishing pad by the operation of tearing off and attaching, thereby achieving replacement. The operation is simple and fast.

In order to achieve the above objects and effects, the polishing pad structure disclosed in the present invention comprises a connecting sheet, a cushion and an abrasive sheet. One side of the connecting piece has a devil's felt connecting layer; the cushioning pad is connected to the other side of the connecting piece, and the cushioning pad has elasticity; the polishing piece is coupled to the cushioning pad. The abrasive sheet is for contacting a surface to be polished, and the cushion is deformed to make the abrasive sheet more closely adhere to the surface to be polished and to reduce the stress applied by the abrasive tool to the surface to be polished.

Fig. 5 is a schematic view showing the state of use of the present invention.

Referring to FIGS. 1 and 2, the polishing pad 10 disclosed in the present invention is configured to be disposed at one end of an abrasive tool 30. Further, one end of the abrasive machine tool 30 has a rotatable turntable 32 for engaging the turntable 32. Therefore, the polishing pad 10 can be used to contact a surface to be polished 34 (see FIG. 2), such as a sheet metal surface of an automobile, and provide a rotational grinding effect on the surface 34 to be polished.

Referring to FIGS. 1 and 3 , the polishing pad 10 includes a connecting piece 12 , a cushion 14 and an abrasive sheet 16 . One side of the connecting piece 12 has a devil felt connecting layer 18, and the devil felt connecting layer 18 is used to join a devil felt connecting layer 36 disposed on one side of the turntable 32.

Further, the cushion pad 14 connects the connecting piece 12 and the polishing sheet 16. Further, a first adhesive layer 20 and a second adhesive layer 22 are disposed on the two sides of the cushion pad 14. The first adhesive layer 20 is coupled to the connecting sheet 12, and the second adhesive layer 22 is bonded to the abrasive sheet 16. Further, the cushion 14 has elasticity, so that the cushion 14 can be made of a foamed material, a rubber material or the like.

The polishing sheet 16 is coupled to the cushion pad 14. In particular, the abrasive sheet 16 is made of a cloth material or a polyurethane material.

Referring to Fig. 4, taking the abrasive sheet 16 as a cloth material as an example, ten filaments 38 can be taken to form a strand 40. Three more strands 40 are taken to form a braided wire 42. The plurality of braided wires 42 are then formed into the abrasive cloth 16 in a longitudinal and lateral (latitude and longitude) phase-to-error and pierced form. More specifically, in the area per square inch, twenty to forty pieces of the braided wire 42 can be arranged in the longitude direction and the latitude direction, wherein the wire 42 is prepared in the longitude direction, and the latitude direction is twenty-four. The wire 42 is optimal. Secondly, the filament 38 can be selected from a wire of four hundred to six hundred denier (DEN) numbers, of which a wire having a Danny number of 531 is preferred.

Referring to FIG. 5, after the polishing pad 10 is combined with the polishing tool 30, the polishing pad 16 contacts the surface to be polished 34 and forms a rotation with the torque provided by the grinding tool 30, and the grinding is further performed. The sheet 16 is capable of effectively smoothing the uneven structure formed on the surface to be polished 34 (for example, cellulite or sag tissue generated by painting or baking varnish), so that the surface to be polished 34 has a better polishing effect.

Secondly, since the cushion 14 has elasticity and can be deformed moderately, when the polishing pad 10 contacts the surface to be polished 34, the combination of the polishing sheet 16 and the cushion 14 can be more conformed by deformation. The surface to be polished 34 and the paint or wax coated on the surface to be polished 34 can be more effectively pushed to achieve a better polishing effect.

The polishing pad 10 disclosed in the present invention is more conformable to the surface to be polished 34 by the deformable action of the cushion 14, thereby enabling the polishing pad 10 to provide a better polishing effect. Furthermore, the deformable action of the cushion 14 can effectively reduce the stress applied by the abrasive tool 30 to the surface 34 to be polished.

Moreover, the polishing pad 10 is provided with the devil felt connecting layer 18 for bonding the devil felt connecting layer 36 of the polishing tool 30, so that the user can perform the replacement of the polishing pad 10 by the operation of tearing off and attaching. Therefore, the replacement operation of the present invention has an easy and fast effect.

The above is a preferred embodiment and the design of the present invention. The preferred embodiments and the drawings are merely illustrative and not intended to limit the scope of the invention. The scope of the rights covered by the content of the "Scope of Patent Application" is not within the scope of the invention and is the scope of the applicant's rights.
