Brick tea automatic blending control system and method

Abstract

The invention discloses a brick tea automatic blending control system and method. The system comprises a PLC (programmable logic controller), a console, an inductor group, a tea weighing module group, an analog quantity input module group, an analog quantity output module group, a vibration tea conveying module group, a tea pouring module, a mold conveying module and an alarm module. According to the method, the system is powered on; the console sends starting signals; equipment resetting and initialization operation are carried out; the residual quantity of tea leaves is detected; if the residual quantity of the tea leaves is lower than a threshold value; a tea storage box performs discharging operation until the residual quantity of the tea leaves is higher than the threshold value; the vibration module group is controlled to vibrate and convey the tea leaves; the tea leaves are dynamically weighed; after the weight of the tea leaves meets a set target value, a mold is conveyed to a designated tea leaf pouring site, and the tea leaves are poured into the mold; the mold is conveyed to a next designated tea leaf pouring site, and another tea leaf blending process is carried out; and after all tea blending processes required by brick tea are finished, the mold is conveyed to a next tea making working area. According to the brick tea automatic blending control system and method of the invention, the automatic control of brick tea blending is realized, and blending weight accuracy and blending efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of automatic control of brick tea production, in particular to an automatic batching control system and method for brick tea. Background technique [0002] During the brick tea production process, various types of tea leaves need to be weighed and prepared. In the existing batching process of brick tea, the workers mainly grab the tea leaves to be weighed on an ordinary electronic scale, and then pour the weighed tea leaves into the mould. It is often necessary to repeatedly increase or decrease the tea leaves on the electronic scale, which results in too long batching time, repeated grasping of tea leaves during the batching process, causing tea leaves to scatter, causing unnecessary waste. Too much artificial participation in the process greatly increases the probability of secondary pollution of tea. Contents of the invention [0003] The object of the present invention is to provide an automatic batc...
