Adjustable quantitative filtering and screening machine for flour

Abstract

The invention relates to the technical field of quantitative screening equipment for flour, in particular to an adjustable quantitative filtering and screening machine for flour. A servo motor is usedfor driving a first rotating shaft to rotate, so that a first gear drives a second gear to enable a second rotating shaft to rotate, and a rotating block at the top end rotates; because the eccentricposition of the inclined surface of the top end of the rotating block is matched with a roller, when the rotating block rotates, the roller drives a U-shaped frame to move up and down, a screening basket moves up and down along with the U-shaped frame to generate oscillation, and the flour is filtered through a sieve screen and falls into a material collecting box; the weight of the material collecting box is gradually increased, and a supporting plate is pressed to vertically move down until a braking switch is pressed down, a servo motor is braked, and oscillation discharging is stopped; and at the moment, the material collecting box can be replaced for collecting materials again. The position of the braking switch keeps unchanged, i.e., correspondence to the same flour amount is realized, and quantitative material collection is realized; and the position of the braking switch is convenient to regulate and fix, and can adapt to flour collection weight of different requirements.

Description

technical field [0001] The invention relates to the technical field of flour quantitative screening equipment, in particular to an adjustable quantitative filtering and screening machine for flour. Background technique [0002] Flour is the staple food in most parts of northern China, and there are many kinds of food made from flour, with a variety of patterns and different flavors. [0003] Flour generally refers to wheat flour, that is, flour that is ground from wheat, and names such as "high-gluten wheat flour" refer to what we usually call flour. [0004] Wheat flour is divided into special flour (such as bread flour, dumpling flour, biscuit flour, etc.), general-purpose flour (such as standard flour, rich flour), nutritionally fortified flour (such as calcium-enriched flour, iron-rich flour, "7+1 "Nutrition-fortified flour, etc.); according to the precision, it can be divided into special first-class flour, special second-class flour, standard flour, ordinary flour, et...

Problems solved by technology

[0008] On the one hand, it is inconvenient to achieve quantitative control of the amount of flour that has been screened; on the other hand, when the existing device is used, people usually directly pour all the flour into the sieve for screening. Flour accumulates on the sieve, and it is difficult to disperse evenly in a short time. It is easy to cause the flour to block the sieve and affect the screening, which increases the time required for screening and reduces the efficiency of screening.
