Description

   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 provided with a reinforcing layer on the back of a plurality of abrasive cloth sheets arranged in a ring shape.

According to modern people's requirements for quality of life, when people buy various products, in addition to the practicality of the product, the appearance of the product has also become one of the important indicators for people to buy. Therefore, the industry often needs to specifically target The surface of the product is polished to gain consumer favor.

Generally speaking, the industry usually uses the "abrasive wheel (also called louver, louver)" to grind the surface of the object so that the object can form a predetermined shape, maintain the desired smoothness, or remove the welding points on the surface of the object. , Rust spots, etc., among them, the "abrasive cloth wheel" is generally on a disc-shaped base, sequentially stacking a plurality of abrasive cloth pieces, so that these abrasive cloth pieces can surround one side of the base to be arranged into It is ring-shaped, and a shaft hole is provided in the center of the base, 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 cloth wheel" to rotate through the rotating shaft. , The staff can bring an abrasive object (such as: metal, glass, stone, etc.) close to the front of the abrasive cloth sheet (that is, the direction facing away from the base), so that the abrasive cloth sheet can remove the abrasive cloth sheet. The roughness of the surface of the object to be polished allows the surface of the object to be polished to be shiny, smooth and detailed.

However, the applicant found that when the abrasive cloth sheets were attached to the base, they would only apply glue to the back area of the adjacent end of the abrasive cloth sheets so as to be able to be fixed to the base. The area of the base will not be coated with glue at all. During the grinding process, the staff must adjust the position of the abrasive cloth wheel according to various angles and fine slits. Therefore, the aforementioned existing bonding methods of abrasive cloth pieces are likely to cause such problems. Abruption, breakage, flashing, etc. of the abrasive cloth sheet will not only shorten the service life of the abrasive cloth wheel, but also cause damage to the abrasive object, which will increase the trouble of the staff in vain.

In summary, it can be seen how to design a brand new abrasive cloth wheel structure in order to provide better working experience for the staff, which has become an important issue for many designers and manufacturers of abrasive cloth wheels.

In addition, the abrasive cloth sheets will be sequentially superimposed and arranged in a ring shape. The reinforcing layer is adhered to the back of the abrasive cloth sheet beyond the bearing surface through an adhesive layer. The outer edge of the reinforcing layer will be adjacent to or aligned with the abrasive cloth. The outer edge of the sheet, so that the area of the abrasive cloth sheet beyond the bearing surface can be connected into a whole by the supporting effect of the reinforcing layer, so that it is not easy to eversion, breakage, flashing during the grinding operation. .. and so on.

Another object of the present invention is to provide the manufacturing process of the aforementioned abrasive cloth wheel, wherein after the abrasive cloth sheets are sequentially stacked on the bearing surface of the base, the reinforcing layer can be coated with the adhesive layer and bonded to The abrasive cloth pieces are beyond the back of the bearing surface, and then, turn the abrasive cloth wheel so that the abrasive cloth pieces are positioned above the reinforcement layer until the adhesive layer is dry. In this way, the adhesive layer can be avoided from excessive Penetrates to the front of these abrasive cloth pieces.

Another object of the present invention is in a state where the reinforcement layer in the foregoing process is formed by at least a first support unit and a second support unit, and the area of the first support unit is larger than the area of the second support unit. A partial area on one side of the first support unit is first fixed to the bearing surface of the base, and after the adhesive layer is coated on the other side of the first support unit, the abrasive cloth sheets are passed through the The first support unit is indirectly fixed to the bearing surface, and finally, the second support unit is attached to one side of the first support unit and corresponds to the back of the abrasive cloth sheets beyond the bearing surface. An abrasive cloth wheel, so that the abrasive cloth pieces are positioned above the reinforcing layer until the adhesive layer is dry.
