Technical Field

The invention relates to a continuous glue sprayer, and belongs to the technical field of industrial equipment machinery.

Background

China is a big agricultural country and a large number of grain and economic crops are planted every year. In harvesting and processing these crops, a number of harvesting residues (e.g., straw, wheat straw, cotton stalks, etc.) and processing residues (e.g., rice hulls, peanut hulls, sugar cane bagasse, etc.) are produced. Most of the remainder has a cellulose content close to that of hardwood trees and a few close to that of coniferous trees. The residues of the crops are used as raw materials, so that the artificial board can be completely produced, and the consumption of wood raw materials in the artificial board industry of China is reduced. Thereby effectively relieving the contradiction between supply and demand of wood resources. The artificial straw board is one excellent timber substitute and has considerable economic benefit and wide economic benefit.

The method for producing the medium-density fiberboard by utilizing the agricultural residues, namely the straw stalks is promising in recent years and has a good prospect. The adhesive used in the production process, namely the isocyanate adhesive (MDI for short) is obviously different from the resin urea-formaldehyde adhesive used in the wood fiber board. MDI is a brown liquid, is non-toxic and slightly earthy, reacts with water to generate various polymers and carbon dioxide, and has the cost more than 10 times of that of resin urea-formaldehyde glue. The traditional ring type glue mixer has the outstanding problem of heating when the straw stalk fiber and MDI are mixed and stirred. Due to the strong propulsion of the spiral plate at the front part of the glue mixer, the strong friction between the stirring deflector rod at the rear part and the fiber generates a large amount of heat energy, which leads to the temperature sudden rise of the mixed fiber material. In the stock preparation stage, the material is partially cured, which relatively reduces the adhesive strength of the MDI and increases the amount of glue applied, which is disadvantageous in ensuring product quality and controlling costs. In order to solve the problems, the development and development of a roller continuous high-pressure airless glue sprayer is very important.
