Example Embodiment

[0038] The technical solution of the present invention will be further described with reference to the accompanying drawings and embodiments, which is believed to be clear to those skilled in the art.

[0039] The control device of the electric extrusion device of the traditional Chinese medicine decocting equipment, such as figure 1 , 7 , 8 shows that the thimble 5 is used to transfer the displacement. The upper part of the outer sleeve 1 of the electric extrusion device is equipped with a rotating bearing plate with a space for the displacement of the thimble 5. The thimble 5 is installed inside the outer sleeve 1 and is connected to the top of the screw rod 3. The pole live bell 4 is against each other, and when the screw 3 moves up, it touches the thimble 5, and the photoelectric switch 7 detects the displacement position of the thimble 5. The photoelectric switch 7 is connected to the control circuit of the single-chip microcomputer. The control circuit of the single-chip micr...

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...
