specific Embodiment 1

[0016] Such as figure 1 As shown, the present invention discloses a powder quantitative mechanism 1 , which includes a silo 101 and a screw feeder arranged on the silo 101 . The screw feeder includes a screw 102 , one end of the screw 102 is provided with a transmission gear 103 , and the thread of the screw 102 extends from the transmission gear 103 to the other end of the screw 102 . The screw 102 is configured as an inverted cone, and one end with the transmission gear 103 is larger than the other end of the screw 102 . The screw feeder also includes a controllable motor 105 , and the controllable motor 105 is in transmission connection with the transmission gear 103 through the transmission track 104 .

[0017] The silo 101 is set in a funnel shape for storing powder, and there are gaps on its upper and lower sides, and the upper gap is larger than the lower gap. A top cover for closing the feed bin 101 is also provided in a gap above the feed bin 101 . A plurality of o...

Abstract

The invention discloses a powder quantifying mechanism. The powder quantifying mechanism comprises a stock bin, a screw, a driving gear, a driving track and a controllable motor, wherein the screw is installed in the stock bin, the driving gear is arranged at one end of the screw and is connected with the driving gear in a driving way; the controllable motor is connected with the driving rack; one end of the screw is in an inverted cone shape and is matched with the funnel type stock bin. The powder quantifying mechanism provided by the invention adopts a structure that the double-line screw which is designed in the inverted cone shape and the funnel type stock bin are matched. The driving gear on the double-line screw is driven by the controllable motor so as to drive the double-line screw to rotate, and the controllable motor can control the rotating direction, rotating speed and rotating angle of an output shaft, therefore the extruding precision of powder can be improved, and the technical problem that the existing quantifying and feeding mechanism is low in precision can be solved.

Description

technical field [0001] The invention relates to the field of weighing, in particular to a quantitative mechanism for powder weighing. Background technique [0002] With the development of science and technology, people have developed various machines and equipment to replace the original manual work. Not only save labor costs, but also improve work efficiency. However, most of the existing powder quantitative equipment adopts horizontal or vertical screw feeders, and its accuracy cannot be guaranteed. In some industries that require high precision, especially the printing and dyeing industry, the weight of various powders is required to be within a small error range, otherwise the dyed colors will have color differences, resulting in different colors of fabrics dyed every time. Therefore, this prior art needs further improvement. Contents of the invention [0003] The purpose of the present invention is to provide a powder quantitative mechanism, which has the character...
