Falling mechanism capable of controlling time and quantity

Abstract

The invention discloses a falling mechanism capable of controlling time and quantity. The falling mechanism comprises an adjustable lever, a falling device and a magnetic assisting device. Through adjustment of the adjustable lever, a receiver (2) and a lever body (11) are in a receiving position and state when the receiver is not loaded with materials, a falling valve (5) is opened at the same time, and the receiver starts to receive materials; and when the gravitational moment of the received materials is larger than the resisting moment of an adjustable magnet (18), the receiver (2) descends around the fulcrum of the lever body (11), and a falling process is completed. The falling period can be adjusted by utilizing a falling control valve (6) to control the falling quantity within the unit time, and the receiving quantity of the receiver (2) can be controlled by adjusting the different resisting moments formed by the magnetic force or magnetic arm of force of the adjustable magnet (18). The falling mechanism has the characteristics of being simple in structure, convenient to adjust, high in adaptability, long in service life, easy to maintain, high in cost performance and the like.

Description

[0001] Technical field [0002] The invention relates to a blanking mechanism, in particular to a blanking mechanism that realizes time control and quantity control by purely mechanical means. Background technique [0003] Some existing material conveying mechanisms and equipment, in order to meet their timing and quantitative material conveying functions, are basically realized through circuits and control systems. Having an available power supply is the prerequisite for the equipment to work, and due to the need for use control circuit and control system, there are expensive equipment, the system will fail or easily damage etc. Contents of the invention [0004] The invention provides a time-controllable and volume-controlled blanking mechanism realized by a purely mechanical method, which has simple structure, convenient adjustment, stable performance and low cost, and can replace the timing and quantitative blanking mechanism realized by circuit control to ensure product...
