Intelligent spraying device for shield segment mold

Abstract

The invention discloses an intelligent spraying device for a shield segment mold. The intelligent spraying device comprises a moving system, a wiping system, a drying system, a sprinkle coating system, a spraying system, a roll coating system and a feeding system, wherein the wiping system, the drying system, the sprinkle coating system, the spraying system, the roll coating system and the feedingsystem are located on one side of the moving system in sequence. According to the intelligent spraying device for the shield segment mold, water removal and real-time quality inspection are carried out on a mold release agent through the feeding system before the material mixing operation, it is ensured that the supplied mold release agent raw material has low water content, denaturation due to long-term mixing with water of the release agent does not occur, and the mold release agent raw material and water are fully stirred under the constant temperature condition, so that the prepared moldrelease agent is good in quality and guarantees the follow-up coating operation; multi-time coating operation is carried out on the inner wall of the mold by means of multiple coating modes, the positions such as faces, points, wee positions, bent positions and irregular positions can be uniformly coated with the mold release agent, and the influence of the surface condition of the mold on the film forming quality of the mold release agent is weakened to the maximum extent, so that the demolding process of the mold in the follow-up operation process can be smoothly completed.

Description

technical field [0001] The invention relates to the field of shield segment production and manufacturing, in particular to an intelligent spraying device for shield segment molds. Background technique [0002] With the rapid development of the country's industrial level, people's living standards have been improving day by day, and people have higher requirements for daily necessities such as food, clothing, housing and transportation. As we all know, transportation development is a key factor for rapidly improving local economic vitality, information communication and exchange, and material turnover and transportation. Among them, high-speed rail transportation has been regarded as the focus of development in recent years, such as high-speed rail across provinces and intercity commuting across cities. cars and the common light rail or subway in the city. However, most of the high-speed rail transit needs to carry out operations through obstacles, such as subway tunnels, ca...

Problems solved by technology

[0003] At present, most of the equipment or systems for mold release agent spraying of shield segment molds have the following problems: (1) The preparation of the release agent and the coating operation are carried out separately, and the release agent is in the middle After mixing with water for a long time, denaturation will occur, for example, the viscosity of the mixture will increase or even the particles will solidify, which will make subsequent coating operations difficult or the coating effect will be extremely poor; (2) The goal of most devices Or the focus is mainly on the relationship between the mold release agent coating and the segment, and does not pay attention to the relationship between the mold itself and the mold release agent coating, for example, the surface of the mold is not cleaned to improve the cleanliness of the inner wall of the mold degree, which in turn improves the film-forming quality of the release agent on the surface of the mold, and ultimately improves the release quality of the segment; (3) most of the current equipment uses a single method to coat the release agent on the inner wall of the mold, but there are a large number of For example, when there are a lot of scratches or pits on the mold itself, the mirror surface of the mold release agent will be extremely low, which will affect the quality of the subsequent mold release. The lack of mold release agent at the corner of the mold or the irregular shape will lead to Affect the demoulding quality, etc.
