Scraper device and method for removing residue attached to bottle shaped objects

Abstract

The invention discloses a scraper device and a method for removing residue attached to bottle shaped objects; wherein the scraper device is suitable for removing the residue attached to the inner wall of the bottle body of bottle shaped objects; the bottle shaped object is provided with a bottle opening, and the caliber of the bottle opening is less than the inner diameter of the bottle body of bottle shaped object; the scraper device comprises a grab handle, a central bracket, two connecting pieces and a scraping piece; the central bracket is connected with the grab handle, and the shape of the central bracket is designed that the bracket can enter in the bottle shaped object through the bottle opening; the connecting pieces are arranged in parallel, one end of each connecting piece is pivoted with the central bracket, the scraping piece is provided with a side edge and the profile of the scraping piece is consistent to the inner wall of the bottle body of the bottle shaped object; the other end of each connecting piece is pivoted with the scraping piece, so as to lead the central bracket, the connecting pieces and the scraping piece to form a four-connecting-rod mechanism, and cause the scraper device to switch from the folding state that the scraping piece is drawn closely to the central bracket to the unfolding state that the scraping piece is far away from the central bracket.

Description

technical field [0001] The present invention relates to a scraper device, and in particular to a scraper device for removing residue attached to a bottle. Background technique [0002] With the progress of science and technology, various applications of liquid crystal display elements as interfaces between humans and computers, etc., have been gradually popularized in terms of production volume and market usage. Liquid crystal display elements are usually formed by pouring liquid crystal material between two glass substrates coated with organic films such as alignment films, and sealing them with sealing materials such as epoxy resin. [0003] The unused liquid crystal material is all contained in the bottle. However, since the liquid crystal material is a polymer compound and has high viscosity, when the liquid crystal material is poured out, there is still liquid crystal material remaining on the inner wall of the bottle body. On the other hand, the price of the liquid c...

Problems solved by technology

On the other hand, the price of liquid crystal materials is relatively high, so it is necessary to try to recycle the remaining liquid crystals in the bottle for effective use

However, the bottle-like thing containing liquid crystals has a smaller opening than the inner diameter of the bottle body, so it is not easy to extract the liquid crystals in the bottle with ordinary tools.
