Description

Automatic white granulated sugar packaging system

Technical Field

The utility model belongs to the automatic production line field, in particular to automatic white granulated sugar system of packing.

Background

Conventional white sugar dress package production line divide into semi-automatic and full-automatic, and both main differences lie in the difference of ejection of compact station, and semi-automatic needs the workman in the discharge gate arrangement of production line, weighs, dress package, joint sealing, and full-automatic then arranges the manipulator at ejection of compact station, through manipulator partial shipment, full-automatic dress package system's is fast extremely, efficient. The conventional packaging machine consists of a bag supply mechanism, a bag feeding mechanism, a weighing mechanism, a bag clamping and placing mechanism, a conveying mechanism, a bag sealing mechanism, an outlet mechanism and a main control unit. The woven bags are placed into the bag bin, the woven bags are conveyed to a bag picking position through the air cylinder, empty bags in the bag bin are picked up and tiled on the chain belt by the bag feeding mechanism, then the empty bags are conveyed and positioned to the opening of the bag opening mechanism through the positioning rollers, the bag opening empty bags are opened by the opening mechanism after the empty bags are opened, and the empty bags are conveyed to the bag clamping device. After the bag clamping device finishes the bag receiving task, the bag clamping mechanism gives a packaging scale signal and discharges materials through the packaging scale. And subsequently, clamping, conveying, folding and sewing the package to finish the whole package filling action.

Go up the bag mechanism and be located first process position, pick up the accuracy of braided bag very important, avoid producing the accident of picking up heavy bag, nevertheless current scheme can not fine solution above-mentioned problem, though the probability of heavy bag is less and the interference is not serious, but needs the workman to come the adjustment, also can slow down the production progress.

The above background disclosure is only provided to aid understanding of the inventive concepts and solutions of the present invention, and it does not necessarily pertain to the prior art of this patent application, and it should not be used to assess the novelty and inventive aspects of this application without explicit evidence that such contents are disclosed at the filing date of this patent application.

If only one layer of woven bag 11 is provided, because the number of the vacuum suckers 40 of the bag clamping mechanism 20 is large or the suction force is large, the woven bag 11 can overcome and break away from the suction force of the screening mechanism 30, and then enters the bag opening mechanism of the next station.
