The present invention relates to a fan, and more particularly to a fan blade and a manufacturing method for producing the same.
Conventional fan blades are commonly made of metal or plastic. Though the conventional fan blades are functioning well, the appearance of the conventional blade is unaesthetic and cannot improve the interior decoration. There are also fan blades made of wood. A wooden fan blade has an upper surface, a bottom surface, and a circumferential edge. Either the upper surface of the wooden fan blade or the bottom surface of the wooden fan blade has wood grain. The circumferential edge is coated by spray painting. Therefore, the circumferential edge of the wooden fan blade and the upper surface and the bottom surface of the wooden fan blade are inconsistent in appearance. The circumferential edge of the wooden fan blade coated by spray painting diminishes the aesthetical appeal of the wooden fan blade.
To overcome the shortcomings of the wooden fan blade, the present invention provides a fan blade and a manufacturing method thereof to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a fan blade with a consistent appearance and a manufacturing method for making the fan blade.
The fan blade comprises a body made of plywood/fiberboard and having two opposite ends, at least one assembling hole disposed at one of the two opposite ends of the body, and a tip disposed at the other one of the two opposite ends of the body and being flat or curved. A manufacturing method for the fan blade has four steps. In a first step, manufacturing plywood panels/fiberboards by carpentry machining. In a second step, adhering paper/veneers/melamine papers to two outer surfaces of the plywood panels/fiberboards, and cutting the plywood panels/fiberboards into shape to form the body. In a third step, cleaning debris on the body. In a fourth step, coating a pattern being consistent with the upper surface of the body and the bottom surface of the body on the circumferential edge of the body by heat pressing. With the pattern printed on the circumferential edge of the body, the fan blade in accordance with the present invention is consistent in appearance.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

A manufacturing method for producing the fan blade in accordance with the present invention has four steps.
In a first step: manufacturing plywood panels/fiberboards by carpentry machining. A length of the plywood panels/fiberboards is greater than a largest length of the body 1 by less than 5 millimeters. The body 1 is composed of two overlaid plywood panels/fiberboards. Each one of the two overlaid plywood panels/fiberboards has a thickness being 2.7 millimeters. In a second step: respectively adhering paper/veneers/melamine papers to two surfaces of the plywood panels/fiberboard; cutting the plywood panels/fiberboard into shape to form the body by a woodworking machine, wherein the body 1 has an upper surface, a bottom surface, a circumferential edge, and two opposite ends; grinding the circumferential edge of the body 1; and forming at least one of the at least three assembling holes 2 through one of the two opposite ends of the body 1. In a third step: cleaning debris on the upper surface, the bottom surface, and the circumferential edge of the body 1.
In a fourth step: coating a pattern being consistent with the upper surface of the body 1 and the bottom surface of the body 1 on the circumferential edge of the body 1 by heat pressing. Before coating a pattern on the circumferential edge of the body, a transfer paper passes through a heat press machine to be printed on the circumferential edge of the body 1 to achieve a neat, integral, and a good appearance and to maintain the quality of the pattern subsequently printed.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
