Problems solved by technology

The disadvantages are: (1), due to the addition of an intermediate transition hopper between the weighing hopper and the packaging bag, there is uncertainty in the amount of powdery materials that pass the measurement and weighing in the intermediate transition hopper, which affects the packaging accuracy ; (2) The volume of the weighing hopper is fixed and cannot adapt to the change

Embodiment approach

[0044] In a preferred embodiment, a material level sensor 17 is provided at the lower end of the lifting sleeve 11 . In this way, the material level sensor 17 detects that the outlet of the lifting sleeve 11 is as close as possible to the surface of the material, which reduces the impact of flying materials on the weighing accuracy and is also convenient for dust removal.

[0045] In order to further improve packaging efficiency, as a preferred embodiment, the number of the rough feeding device 1 and the shaping vibration conveying device 2 are two to four. The rough feeding device 1 and the shaping and vibrating conveying device 2 are installed up and down like this, and can be a whole body. Since there are two to four whole bodies, they can be connected in series or in parallel. In this way, the number of material bags for the first feeding increases, and the two feedings are reasonably distributed, which improves the packaging efficiency.

Abstract

The invention relates to the field of automation, particularly relates to an automatic weighing and packing device for a fine powdery material and a method thereof, and solves the technical problems of providing the automatic weighing and packing device for the fine powdery material and the method thereof which are precise to pack and convenient to stack. The device comprises a coarse feeding device, a shaping and vibration transportation device, a measuring and weighing device and an edge-fold sewing device, wherein the coarse feeding device is arranged above the shaping and vibration transportation device; the coarse feeding device comprises a feeding control system, a support, a spiral feeder, a quantitative hopper and a bag holder, wherein the spiral feeder, wherein the quantitative hopper and the bag holder are sequentially arranged on the support, and the spiral feeder is connected with the upper end of the quantitative hopper; the shaping and vibration transportation device comprises a belt conveyor and a vibrator; the measuring and weighing device comprises a belt weigher, a feeder, a spiral feeder and a lifting sleeve, wherein the spiral feeder and the lifting sleeve are installed on the feeder. The automatic weighing and packing device provided by the invention has the effects of being quick and accurate in material packing efficiency and convenient to stack.

Description

technical field [0001] The invention relates to the field of automation, in particular to an automatic weighing and packaging device for fine powder materials and a method thereof. Background technique [0002] At present, the automatic packaging system used in the automatic packaging industry is mainly the automatic packaging method of the net weighing method and the automatic packaging method of the gross weighing method. These two packaging methods are only suitable for granular materials, powdery materials with better crystallization, and powdery materials with small changes in specific gravity without air inclusions in the materials. In China, in addition to the relatively high-value chemical products that are automatically packaged with valve bags with high import costs, other industrial products of powdery materials with low value and little change in specific gravity are automatically packaged using the above two methods. The powder materials (4 million tons of feed...
