Abrasive cloth wheel with reinforced structure and its manufacturing process

The invention relates to an abrasive cloth wheel, in particular to an abrasive cloth wheel with a reinforcing layer added on the back surface of a plurality of abrasive cloth sheets arranged in a ring shape.

According to the modern people's requirements for the quality of life, people buy more products. In addition to the practicality of the products, the appearance of the products has become one of the important indicators for people to buy. Therefore, the operators often need to specifically target The surface of the product is ground to obtain the favor of consumers.

In general, the manufacturer usually uses an "abrasive wheel (or a hundred impellers, a hundred sheets)" to grind the surface of the object so that the object can form a predetermined shape, maintain the desired smoothness, or remove the solder joint on the surface of the object. , rust spots, etc., wherein the "abrasive cloth wheel" is generally formed on a disk-shaped base, sequentially stacking a plurality of abrasive cloth sheets so that the abrasive cloth sheets can surround one side of the base to be arranged An annular shape, and a center of the base is provided with a shaft hole, and the shaft hole can be assembled with a rotating shaft of a device (such as a grinder), so that the device can drive the "abrasive wheel" to rotate by the rotating shaft, The worker can bring a workpiece (such as metal, glass, stone, etc.) close to the front side of the abrasive cloth (ie, facing away from the base), so that the abrasive cloth can remove the abrasive cloth. The roughness of the surface of the object to be polished keeps the surface of the object to be bright, smooth and detailed.

However, the Applicant has found that the abrasive cloth sheets only fit when they are attached to the base. The glue cloth is coated on the back side of the sand cloth to be fixed to the base. However, the sand cloth sheet is not coated with glue even beyond the area of the base, because the worker must respond during the grinding process. Various angles and slits are used to adjust the position of the abrasive cloth wheel. Therefore, the bonding manner of the existing abrasive cloth sheets is likely to cause the outer cloth sheets to be everted, broken, flashed, etc., and the abrasive cloth wheel is not shortened. The service life even causes damage to the objects to be ground, which in vain increases the staff's troubles.

And the abrasive sheets are arranged in a ring shape in sequence, and the reinforcing layer is adhered through an adhesive layer to the back surface of the bearing surface, and the outer edge of the reinforcing layer is adjacent to or aligned with the abrasive cloth. The outer edge of the sheet, such that the abrasive cloth sheet beyond the area of the bearing surface, can be connected by the support effect of the reinforcing layer, so that in the grinding operation, it is not easy to eversion, breakage, flashing. ..etc.

Another object of the present invention is to provide a process for the above-mentioned abrasive cloth wheel, wherein the reinforcing layer can be coated with the adhesive layer after the abrasive cloth sheets are sequentially superposed on the bearing surface of the base, and Laying to the back surface of the bearing sheet beyond the back surface of the bearing surface, and flipping the abrasive cloth wheel so that the abrasive cloth sheets are positioned above the reinforcing layer until the adhesive layer is dried, so that the adhesive can be avoided. The glue layer is excessively infiltrated to the front side of the abrasive cloth sheets.

A further object of the present invention is that when the reinforcing layer in the foregoing process is formed by at least a first supporting unit and a second supporting unit, and the area of the first supporting unit is larger than the area of the second supporting unit a partial area of one side of the first supporting unit is first fixed to the bearing surface of the base, and after applying the adhesive layer on the other side of the first supporting unit, the abrasive cloth piece is passed through the The first supporting unit is indirectly fixed to the bearing surface, and finally, the second supporting unit is attached to one side of the first supporting unit, and corresponding to the sanding sheets beyond the back surface of the bearing surface, 嗣, flipping the The abrasive cloth wheels are arranged such that the abrasive cloth sheets are positioned above the reinforcing layer until the adhesive layer is dried, so that the adhesive layer is prevented from excessively penetrating to the front surface of the abrasive cloth sheets.
