Abstract

The invention relates to a bi-component rubber-mixing machine and a closed-loop control method for rubber mixing thereof. The bi-component rubber-mixing machine comprises a raw material barrel for filling rubber, a raw material barrel for filling a curing agent, an electrical control cabinet and a rubber-mixing pipe. The bi-component rubber-mixing machine is characterized by comprising two sets of primary booster pump groups, two secondary adjustable quantitative delivery pumps, a flow meter and a controller, wherein the two sets of primary booster pump groups are respectively connected with the rubber raw material barrel and the curing agent raw material barrel in a matching mode; the flow meter is used for monitoring the delivery pumps and sending signals to the controller; and the controller is used for collecting the signals sent by the flow meter, sending the signals to a frequency modulation motor of a secondary pump and feeding the signals back for controlling the rotary speed of the secondary pump. Finally, rubber is mixed statically through a rubber-mixing pipe. With simple structure, the bi-component rubber-mixing machine is easy to operate and runs closely in a pipeline without polluting the environment. The controller is used for receiving the signals sent by the flow meter and feeding the signals back for controlling the rotary speed of the delivery pumps and a bolt pump so as to control the error range of the mixing rate of the rubber to the curing agent to be smaller than plus/minus 0.5 percent and meet the rubber-mixing requirement for accurate rate control. The invention can ensure the purified use of the rubber and the curing agent and is beneficial to popularization and application.

Description

technical field [0001] The invention relates to a glue mixing machine and a glue mixing method, in particular to a two-component glue mixing machine which is used for arbitrarily setting the amount of glue output, continuously mixing, and arbitrarily adjusting the mixing ratio, and the glue mixing machine. Glue closed-loop control method. Background technique [0002] Existing glue mixers are usually mechanically agitated glue mixers. For the mixing of two-component glues that require a large amount of mixing per unit time and a small error range in the ratio, such as polyurethane glue and epoxy resin glue, they are all After the glue and curing agent are weighed separately, they are poured into the mixing container together, and the glue and curing agent are mixed evenly by mechanical stirring, and then set aside. However, this type of glue mixer will generate or involve a large number of air bubbles during the high-speed mixing of the two-component glue, which is cumberso...
