A glue mixer preventing half blockage of glue conveying pipes

Abstract

A glue mixer preventing half blockage of glue conveying pipes is disclosed. The glue mixer comprises a glue storing mechanism and a glue mixing mechanism. The glue storing mechanism includes at least two sealed glue storage barrels. The glue mixing mechanism comprises a glue mixing nozzle. A glue conveying pipe is disposed between each glue storage barrel and the glue mixing nozzle. The glue conveying pipes are provided with glue conveying mechanisms. The glue mixer is characterized in that the glue mixer also comprises weight measuring mechanisms used for measuring weights of the glue storage barrels and a cleaning system used for cleaning the glue conveying pipes, the weight measuring mechanisms comprise platforms where the glue storage barrels are put, at least three weight sensors are evenly disposed in an annular manner on each of the platforms, the cleaning system comprises a liquid storing barrel used for storing a cleaning liquid, the liquid storing barrel is provided with a liquid discharging pipe, the liquid discharging pipe is provided with cleaning pipes respectively connected to the glue conveying pipes, a tee joint is disposed between each cleaning pipe and the corresponding glue conveying pipe, each of the tee joints is disposed between the corresponding glue conveying mechanism and the corresponding glue storage barrel, the cleaning pipes are provided with valves I, and each of the glue conveying pipes between the corresponding glue storage barrel and the corresponding tee joint is provided with a vale II.

Description

technical field [0001] The invention relates to a rubber mixing machine, in particular to a rubber mixing machine capable of detecting whether a rubber delivery pipe is partially blocked and cleaning the rubber delivery hose. Background technique [0002] In the printing and packaging industry, solvent-free lamination is an environmentally friendly lamination process. With the vigorous promotion and promotion of this process in China, solvent-free lamination equipment is widely used in production. In order to meet the needs of high-speed automatic production, the two-component glue mixer has become an indispensable equipment in the production of solvent-free composite process. [0003] Since the medium mixed by the glue mixer is glue with a high viscosity, after long-term use, the glue will adhere to the inner wall of the rubber tube, resulting in a smaller effective aperture of the rubber tube, that is, the rubber tube is partially blocked. The circulation of glue can also...

AI Technical Summary

Problems solved by technology

If the rubber delivery pipe is partially blocked, although the glue can still flow, the flow rate of the glue will become smaller under the condition of the same speed of the gear pump. In this way, the change will cause the ratio of the various components of the glue mixer to change. Changes, resulting in the mixed glue can not meet the use requirements
