High speed automatic weighing packing machine

Abstract

The invention discloses a high speed automatic weighing packing machine. The high speed automatic weigh packing machine comprises a rack, a blanking device, a weighing mechanism, a rejecting mechanism, a conveying mechanism and a bag packing mechanism. The blanking device comprises a main material hopper and a feeding mechanism. The main material hopper is provided with a first holding cavity and a second holding cavity. The first holding cavity is provided with a rough feeding mechanism. The feeding mechanism is arranged below the main material hopper. The weighing mechanism comprises a weighing hopper. The weighing hopper is arranged below the feed outlet of the feeding mechanism. The rejecting mechanism is arranged below the weighing hopper. A transitional hopper is arranged below the rejecting mechanism, and therefore, by cooperatively utilizing the rough feeding mechanism to conduct most feed to the weighing hopper of the weighing mechanism and by utilizing the feeding mechanism to conduct the compensating feed to the weighing hopper of the weighing mechanism until the default value, the high speed automatic weighing packing machine enables the quantitative blanking with particles easily controlled to become more accurate, thereby being beneficial for improving the accuracy for irregular material packing and meanwhile improving the operation efficiency of the weighing and packing.

Description

Technical field [0001] The invention relates to the field of packaging machinery technology, in particular to a high-speed automatic weighing and packaging machine. Background technique [0002] Bulk materials often appear in bags, which are convenient for storage, transportation and use, and low cost. The initial packaging method was manual packaging. When packaging, people need to add or adjust the amount of particles multiple times with the help of a scale to make it as close to the standard packaging volume as possible. Obviously, manual packaging has many shortcomings, such as low packaging efficiency. The production cost is high, it is not suitable for mass production, and the packaging precision is low. [0003] Later, automatic packaging by volume measurement appeared. For example, by using a single horizontal turntable type, a scraper was installed on the surface of the turntable, and the excess material at the mouth of the measuring cup was peeled off during canning, and...
