Externally-hung preference hopper device, combined weighing system and application

Abstract

The invention relates to an externally-hung preference hopper device, a combined weighing system and application. The externally-hung preference hopper device comprises a mounting rack, memory hoppersarranged on the mounting rack and connected and driven by memory hopper drive units, feeding hoppers arranged below the memory hoppers, metering hoppers arranged below the feeding hoppers and material division chutes arranged below the metering hoppers. Discharging openings of the material division chutes comprise metering unqualified material removal channels and metering qualified material discharging channels. The combined weighing system comprises at least one externally-hung preference hopper device, and the externally-hung preference hopper devices are connected to a combined scale through the mounting racks. The technical problems that existing some combined scales are provided with no zoning scales, the number of heads is not large, zoning is limited, and mixed and quantitative weighing and packing of multiple materials cannot be achieved are mainly solved.

Description

technical field [0001] The invention relates to a device for weighing mixed and packaged batch materials with a combination scale, in particular to an external priority bucket device, a combined weighing system and its application. Background technique [0002] At present, in the face of domestic and foreign large-scale manufacturers who need quantitative weighing and packaging of various mixed ratios such as granules, flakes, strips, and irregular shapes, the application of combination scales is becoming more and more extensive. Such as figure 1 As shown, it discloses a 24-head combined scale, the combined scale is divided into three layers of hoppers, which are respectively a supply hopper, a measuring hopper, and a memory hopper, and the 24-head combined scale is divided into 4 areas, hereinafter referred to as ABCD four areas, each area 6 The head quantitatively weighs one material (mixable material) respectively, assuming that after the weighing of the ABC three areas,...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide an external priority bucket device and combined weighing system and application to solve the problem that some existing combined scales do not have partition scales and the number of heads is small and the partitions are limited, so that it is impossible to realize the quantitative weighing and packaging of various materials. Unqualified materials in each zone cannot be removed separately, and it is difficult to divide the materials after mixing. It is impossible to feed the combined scale through the front-end equipment counting grains or cups to complete the weighing and feeding of various materials, and it is impossible to count grains or cups through the front-end equipment. Quantitative feeding to the combination scale through dry and wet channels to complete AB bag packaging and other technical issues
