Problems solved by technology

[0003] For particularly high viscosity (initial viscosity over 500×104mPa·s), many components and very different component ratios, in the prior art, high-speed mixers are often used for mixing, which brings about the problem that the single mixing capacity is small and the mixing Finally, it needs to be transferred to the rubber cartridge, which is inconvenient to use and the equipment is more expensive; the mixing device suitable for mixing high-viscosity sealant needs a pressing device to squeeze the glue out of the cartridge, which is inefficient for continuous operation and difficult to clean the device

Abstract

The invention provides a high-viscosity multi-component sealant mixing and filling integrated tool and method. For the problems existing in the mixing process of a sealant with the high viscosity, multiple components and the great component ratio, the solution is provided, the tool comprises a vacuum double-reverse three-speed rotary cylinder mixer, a split type glue cylinder and a gluing gun capable of advancing and retreating automatically. The scheme is suitable for mixing of various sealing materials, high-viscosity putty and various printing ink and binders and suitable for materials with the wide viscosity range. The clearance accuracy of stirring blades and a container is high, the dead-corner-free mixing characteristic is achieved, vacuumizing is performed in the mixing process, and no bubble is generated; the temperature is controllable; and no pressing device is needed, the split type glue cylinder can be used as a mixing cylinder and a gluing cylinder, the filling quality is improved, and the filling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an integrated tooling for mixing and filling high-viscosity multi-component sealants. Background technique [0002] Single-pack potting and sealants are widely used in many fields. Multi-component potting adhesives and sealants are also widely used, such as low-viscosity two-component adhesives, which are statically mixed and easy to use; higher-viscosity ones, such as vacuum glass seals, can be constructed in fixed places, and glue machine technology is often used . [0003] For particularly high viscosity (initial viscosity over 500×104mPa·s), many components and very different component ratios, in the prior art, high-speed mixers are often used for mixing, which brings about the problem that the single mixing capacity is small and the mixing Finally, it needs to be transferred to the rubber cartridge, which is inconvenient to use and the equipment is more ex...
