Problems solved by technology

For a long time, scraper handles and scraper blades have been made of round wood and elastic steel sheets. Although they are small and flexible, and have high maneuverability when used, they have certain disadvantages. It is too comfortable and has a stiff feeling. It is difficult to smooth the scraper surface after a gap is formed, and it is difficult to keep the working interface flat. In addition, the traditional scraper is not suitable for novice operation, because the power control is not uniform, resulting in easy scratches when scraping , thereby reducing the service life; because the knife body is made of metal, it is afraid of water and easy to rust

Abstract

The invention relates to a method for manufacturing a multipurpose scraper which comprises a handle made of an elastic foaming material and a film scraper consisting of laminated sheets. The production process comprises the following steps: (a) manufacturing a pressing mould for the film scraper; (b) pressing an epoxide resin layer to form a film scraper shape (2); (c) manufacturing a cast mould or an injection mould (3) according to a designed handle model; and (d) placing the well-pressed film scraper (2) in a proper position of the mould (3), casting an elastic foaming material into the mould (3), and combining the elastic foaming material with the film scraper (2), and shaping for about 3 to 15 minutes in a baker at the temperature ranging from 60 DEG C to 200 DEG C, in a closed mold with the molding pressing range being 50-500kg. The elastic foaming material is polyurethane or EVA resin, the laminated sheet is epoxide resin, and a plurality of small holes (4) are formed on the laminated sheet, thereby enabling the handle to be tightly engaged with the film scraper.

Description

technical field [0001] The method of the invention relates to a method for producing a strong elastic multipurpose scraper used for scraping dust on walls, filling soil in furniture and automobile industries, and the like. Background technique [0002] The scraper is a commonly used tool for filling soil in industries such as wall scraping, furniture and automobiles. For a long time, scraper handles and scraper blades have been made of round wood and elastic steel sheets. Although they are small and flexible, and have high maneuverability when used, they have certain disadvantages. It is too comfortable and has a stiff feeling. It is difficult to smooth the scraper surface after a gap is formed, and it is difficult to keep the working interface flat. In addition, the traditional scraper is not suitable for novice operation, because the power control is not uniform, resulting in easy scratches when scraping , thereby reducing the service life; because the knife body is made ...
