Description

Bag supporting and sleeving device

Technical Field

The utility model relates to the technical field of packaging machines, in particular to a bag opening and sleeving device.

Background

A quantitative packing scale (also called a ton bag packing machine) is a packing device for quantitative packing of solid fluid state (granular materials or powder materials). The quantitative packing scale in the current market mostly adopts a semi-automatic packing working mode, and the bag needs to be manually taken, opened and hung in advance during operation, and after the bag is hung on a packing machine, quantitative feeding is automatically carried out by the packing machine, and after the feeding is finished, the ton bag filled with the material is transferred to a conveyor and then is sent to the next station for the sealing operation of the bag opening.

However, the semiautomatic packing machine has the following problems in use: in the packaging process, the opening time of the ton bag is long after the material is filled, on one hand, the raw materials are easy to be polluted by air, and therefore the performance of the raw materials is possibly reduced; on the other hand, dust possibly generated in the feeding and packaging process also pollutes the surrounding environment, and the environment friendliness is poor. Secondly, for some special industries, such as lithium battery material industry, the lithium battery material is high in price, so that more severe requirements are put on the accuracy of quantitative packaging, and the existing packaging machine cannot meet the requirements of high-accuracy packaging; in addition, the adoption of the semi-automatic packaging machine increases labor cost and reduces packaging efficiency.

Therefore, it is necessary to develop a solid fluid full-automatic packaging machine specifically to solve the above problems, so that the full-automatic packaging machine can realize full-automatic operations of the processes of bag taking, bag opening, bag covering, bag clamping, weighing, loading, sealing, dust removing and the like.
