Powder material ton bag quantitative packing scale and packing method

Abstract

The invention provides a powder material ton bag quantitative packing scale and a packing and weighing method. The powder material ton bag quantitative packing scale comprises a platform, a frequency-variable spiral mechanism, a weighing module, a weighing frame, an air cylinder, a fan, a lifting bag clamping mechanism, an automatic bag releasing mechanism, a chain plate conveying machine, a weighing control system and an air passage, wherein the frequency-variable spiral mechanism controls the feeding speed, the weighing module is connected with the platform and the weighing frame, the weighing frame is used for transmitting the weighing weight, and the air cylinder is arranged on the weighing frame and drives the lifting bag clamping mechanism. The powder material ton bag quantitative packing scale has the advantages that in the packing and weighing processes, the labor is saved, the automation degree is high, the automatic bag expansion can be realized, the automatic lifting, the automatic filling and the weighing control of the lifting bag clamping mechanism can be realized, the powder material ton bag quantitative packing scale can be widely applied to packing industries of different powder materials, the automation degree is high, the operation is simple, convenient and fast, the production capability is high, and the work intensity and the operation cost are low.

Description

technical field [0001] The invention relates to a quantitative packaging device for a powder ton bag, in particular to a powder ton bag quantitative packaging scale and a packaging method that realize automatic bag expansion, automatic lifting and filling in the powder ton bag packaging process. Background technique [0002] At present, domestic powder ton bag quantitative packaging scales are generally composed of platform scales and screw feeding methods. The usual ton bag packaging is generally completed in two ways. One is that the manufacturer directly purchases a one-ton platform scale as a Weighing, feeding with a screw mechanism and manual control to complete the final product filling. [0003] Another form is to use the ton bag quantitative packaging scale to complete the final filling. The ton bag quantitative packaging scale used mainly includes electronic platform scales, spirals, frames, bag clamping mechanisms that are mainly used to clamp bags and provide slin...

[0003] Another form is to use the ton bag quantitative packaging scale to complete the final filling. The ton bag quantitative packaging scale used mainly includes electronic platform scales, spirals, frames, bag clamping mechanisms that are mainly used to clamp bags and provide sling support, The weighing controller and related circuit components can meet the requirements of quantitative filling on the surface, but many problems will be found in the actual operation process. Opening or two operators need to open the packaging bag face to face; in addition, some materials cannot completely fill the packaging bag during the filling process, so the packaging bag design must be slightly larger, and the cost will increase

[0004] In addition, during the filling process of the current ton bag quantitative packaging scale, a pallet needs to be added to the bottom of the packaging bag to support the...
