Device and method for controlling electric squeezing device of traditional Chinese medicine decoction equipment

Abstract

The invention discloses a device and method for controlling an electric squeezing device of traditional Chinese medicine decoction equipment. An ejector pin is installed inside an outer sleeve and abuts against a lead screw stand-off on the top of a lead screw, the lead screw touches the ejector pin after moving upwards, the displacement position of the ejector pin is detected by a photoelectric switch in control connection with a single-chip microcomputer control circuit, and the single-chip microcomputer control circuit controls a motor to stop through a motor control circuit to achieve upward limitation; meanwhile, a spring is installed over the ejector pin; the control device is further provided with a current detection circuit, the current detection circuit detects motor current signals and then transmits the motor current signals to the single-chip microcomputer control circuit, and the single-chip microcomputer control circuit controls the motor to stop through the motor control circuit so as to achieve downward limitation when the current output of the motor reaches a set maximum current limit line. A smaller displacement control scheme is adopted and suitable for narrow space, the motor is controlled through current detection, the application of a force sensor is omitted, and installation and design difficulty is reduced.

Description

[technical field] [0001] The invention relates to a control device and method for an electric extrusion device of traditional Chinese medicine decoction equipment, which is suitable for traditional Chinese medicine decoction equipment such as traditional Chinese medicine decoction and extraction of traditional Chinese medicine. [Background technique] [0002] Traditional Chinese medicine is the essence of Chinese culture. In order to achieve better curative effect and deal with various special patients, many diseases adopt traditional Chinese medicine juice as the main treatment method to achieve the effect of regulating internal organs and curing diseases. However, due to All kinds of difficulties in decocting medicine by myself have brought obstacles to people's acceptance. For example, Chinese medicine has a strong taste, it is difficult to control the heat when decocting medicine, and the medicine juice cannot be completely squeezed out, causing waste, etc. Faced with thi...

AI Technical Summary

Problems solved by technology

[0006] 1. The problem of inaccurate position control, it is difficult to control the position of the up and down movement, and the extrusion of Chinese medicinal materials cannot accurately control the strength;

[0007] 2. After the switch is shifted, the switch fails and may cause damage to the transmission machinery;

[0008] 3. It is installed outside the outer sleeve 4, which affects the aesthetics and may be bumped by external forces, which further affects the accuracy
