Description

Abrasive cloth polishing wheel structure improvement

The present invention is an abrasive cloth polishing wheel, especially an abrasive cloth polishing wheel structure which can be polished in a large area when polishing work, and is durable and long in service life.

According to the conventional electric hand tool abrasive cloth polishing wheel, which is composed of a plurality of long abrasive cloth sheets, a backing pad for supporting the abrasive cloth sheets, and an abrasive cloth polishing wheel assembly combined with a backing plate for fixing the abrasive cloth sheets. And rotating by the driving of the electric hand tool, the abrasive cloth is brought into contact with the workpiece to be processed for polishing.
Referring to the first and second figures, which are a perspective view and an exploded perspective view of the prior art abrasive cloth polishing wheel structure, it can be clearly seen from the figure that the abrasive cloth polishing wheel structure 1 includes a plurality of elongated abrasive cloth sheets 13 a back pad 12; and a back disk 11. The elongate abrasive sheets 13 are stacked in a circular shape on the backing tray 12 in a conventional manner, and the backing disc 12 is manufactured by blending an abrasive such as gold grit. The back disk 11 is formed into a shallow disk shape having a center inner hole 111 to which the back pad disk 12 is coupled.
When the electric hand tool starts to operate, the abrasive cloth sheet 13 can be brought into contact with the workpiece to be processed, and the workpiece to be processed is polished by a plurality of long abrasive cloth sheets 13 stacked in a ring shape.
However, in the actual use of the abrasive cloth polishing wheel structure 1, the following problems remain to be solved: 1. The abrasive cloth sheet 13 of the abrasive polishing wheel structure 1 is cut into a plurality of elongated bodies stacked on each other, and stacked according to the center of the circle. In the shape of a ring, each of the abrasive sheets 13 has only a small portion of the sand surface exposed for polishing, so that the structure causes the unpolished cloth surface between the abrasive cloth sheet 13 and the abrasive cloth sheet 13 to be exposed between the sand surfaces, especially in a circle. The outer ring of the ring shape is more serious, so that the area of the abrasive polishing wheel structure 1 can be greatly reduced for polishing. 2. The abrasive cloth sheet 13 of the abrasive cloth polishing wheel structure 1 is cut into a plurality of narrow rectangles and stacked according to the center of the circle into a circular ring shape, and each of the abrasive cloth sheets 13 is bonded to each other through an adhesive, and the structure is excessively connected, when the abrasive cloth is polished The wheel structure 1 is prone to disintegration and damage after being used for a long time. Moreover, the abrasive cloth sheets 13 are all single pieces. After a long time of use, the single abrasive cloth sheets 13 cannot be used after being flattened, and another new polishing wheel has to be replaced, resulting in an increase in cost.
Therefore, how to solve the above problems and shortcomings in the past, that is, the creators of the creation and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the creators of this creation have collected relevant information, and have designed and developed such new patents through continuous evaluation and modification through multi-party evaluation and consideration, and through years of experience in the industry.
The main purpose of this creation is to provide an improved abrasive pad polishing wheel that can be polished over a large area and is durable and long lasting.
In order to achieve the above object, an improved abrasive cloth polishing wheel structure comprises: a back disk having a central inner hole; and at least three abrasive cloth pieces stacked on each other, and the at least three abrasive cloth pieces are stacked on each other. It is attached to one side of the back.
In a preferred embodiment, the at least three emery sheets are stacked on each other with an adhesive.
In a preferred embodiment, the at least three emery sheets are bonded to one side of the backing with an adhesive.
In a preferred embodiment, the at least three abrasive sheets have a hole at a suitable location.
In a preferred embodiment, the back disc is coupled to an electric hand tool.
Wherein, since the at least three abrasive cloth sheets of the present abrasive cloth polishing wheel structure are stacked and bonded to each other and bonded to one side of the backing plate, the structure can be used for polishing the area of the polishing cloth polishing wheel structure of the prior art. The problem is to break through. In the creation of the polishing work, the entire sand surface of the abrasive cloth sheet can be completely contacted with the workpiece to be processed for polishing.
Moreover, the at least three abrasive cloth sheets of the present invention are stacked and stacked on each other, and the joints are extremely small compared with the prior art, and the at least three abrasive cloth sheets are combined in a large area, and the joint strength at the joint is relatively strong, when the abrasive cloth is polished. After a long period of use, the wheel structure is not easily disintegrated and damaged as in the prior art.
Finally, after the polishing cloth polishing wheel structure of the present invention is subjected to multiple polishing operations, since the creation includes at least three abrasive cloth sheets, the first abrasive cloth sheet can be used for polishing after being worn for a long time. As a result, this creation has a long service life and is unpredictable compared to previous technologies.

The third figure is a perspective view of a preferred embodiment of the present invention.
The fourth drawing is a perspective exploded view of the preferred embodiment of the present invention.

In order to achieve the above objectives and effects, the technical means and structure adopted by the present invention are described in detail in the preferred embodiment of the present creation, and the features and functions are as follows.
Please refer to the third and fourth figures, which are perspective views and exploded views of the preferred embodiment of the present invention. It can be clearly seen from the figure that the sanding polishing wheel structure 2 is improved, including at least one back. The tray 21 and at least three abrasive sheets 22.
The back disk 21 has a central inner hole 211 which is in the shape of a shallow disk and can be coupled to an electric hand tool and driven by an electric hand tool.
The at least three abrasive cloth sheets 22 are stacked on each other, and the at least three abrasive cloth sheets 22 are bonded to one side of the backing plate 21. Preferably, the at least three abrasive cloth sheets 22 are stacked on each other with an adhesive and bonded to one side of the backing plate 21 with an adhesive. Furthermore, the at least three abrasive cloth sheets 22 have a hole 221 at a suitable position.
