Polyurethane pouring machine with liquid-guiding self-sealing function

Abstract

The invention discloses a polyurethane pouring machine with a liquid-guiding self-sealing function, and belongs to the field of pouring machines. The polyurethane pouring machine with the liquid-guiding self-sealing function comprises a pouring pipe mounted on a pouring machine, a guide head is arranged on the inner side of the pouring pipe; the guide head is positioned on one side, far away fromthe pouring machine, of the pouring pipe; the inner end of the pouring pipe is fixedly connected with a positioning plate; a material liquid can be conveniently guided to the central position throughthe guide head; the material liquid is not easy to spatter around through a movable plate group, and waste of the material liquid is reduced; meanwhile, the mutual repulsive force between the first magnet and the second magnet is utilized, so the movable plate group can be automatically closed after pouring is completed, and pollution caused by dust entering is reduced; in addition, due to the transparent arrangement of the guide head and the arrangement of temperature sensing color changing powder in the cavity, workers can conveniently know the temperature condition of the pouring pipe, andscalding is avoided; and in addition, a protection ring can be detached from the outer end of the pouring pipe so as to be convenient to install and replace.

Description

technical field [0001] The invention relates to the field of pouring machines, in particular to a polyurethane pouring machine with a liquid-inducing self-sealing function. Background technique [0002] The pouring machine can be used to stir the production raw materials to make them evenly mixed, fully reacted, and inject the mixed slurry into the mold frame in time, while the polyurethane pouring machine is mainly used in multi-mode continuous production of rigid semi-rigid polyurethane products, such as : petrochemical equipment, directly buried pipelines, cold storage, water tanks, instruments and other thermal insulation and sound insulation equipment craft products. [0003] The pouring volume of the polyurethane pouring machine can be adjusted between 0 and the maximum pouring volume, and the adjustment accuracy is 1%. It has a temperature control system, and it can automatically stop heating when the specified temperature is reached. The control accuracy can reach 1%...

Problems solved by technology

[0004] However, in the process of pouring with a polyurethane pouring machine, the pouring pipe port, that is, the outlet of the material liquid, is usually exposed outside. After pouring, dust can easily enter the pouring pipe through the port, causing pollution. When it is used again, the pouring pipe The material liquid sprayed out at the beginning of the road is polluted and needs to be discharged without use, which is wasteful, and the material liquid is not guided and blocked when it is sprayed, so that the material liquid is easy to splash around after spraying, resulting in waste. In addition, the material liquid is sprayed It is usually heated and melted at high temperature before being released. If the staff accidentally approaches or touches the pouring pipeline, it is easy to be scalded by the splashed liquid or the outer wall of the pipeline.
