Ton bag filling device with bag holding and bulging mechanism

Abstract

The invention relates to a ton bag filling device with a bag holding and bulging mechanism. The ton bag filling device comprises a rack, wherein a weighing hopper is arranged on the rack; a filling nozzle is connected to an outlet at the lower part of the weighing hopper; a bag opening clamping mechanism is arranged on the outer wall at the lower part of the filling nozzle; the outlet at the lowerend of the weighing hopper is connected to the filling nozzle through a four-way pipe; an upper port and a lower port in the four-way pipe are respectively connected to a weighing hopper and the filling nozzle; two ports located on the side part in the four-way pipe are respectively connected to a blast air pipe and a dust collection air pipe; the dust collection air pipe is connected to an external dust collection fan; the upper end of the blast air pipe is connected to a bag bulging fan; the bag bulging fan is arranged on the side part of the rack through a support frame; and a ton bag holding mechanism is further arranged. The device is simple and ingenious in structural design and good in practicability, the stability of ton bags in the filling process is greatly improved, and rapid and smooth filling of materials can be well achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission equipment, in particular to a jumbo bag filling device with a bag holding and drum bag mechanism. Background technique [0002] In the field of material filling, the filling of ton bags is a very common form, which involves the filling machinery of ton bags. During the operation, the empty ton bags are folded and collected beforehand and then opened for use, so Before putting it on the filling nozzle of the big bag packaging machine, the bag is generally opened manually. This operation is cumbersome, and it is difficult to unfold the bag by manual operation. It is easy for the bag itself to be skewed, which will affect the filling efficiency of the material and generate more dust at the same time.

[0002] In the field of material filling, the filling of ton bags is a very common form, which involves the filling machinery of ton bags. During the operation, the empty ton bags are folded and collected beforehand and then opened for use, so Before putting it on the filling nozzle of the big bag packaging machine, the bag is generally opened manually. This operation is cumbersome, and it is difficult to unfold the bag by manual operation. It is easy for the bag itself to be skewed, which will affect the filling efficiency of the material and generate more dust at the same time

[0003] At the same time, after the empty big bag is put into the filling nozzle of the big bag packaging machine, in order to facilitate filling, it is often necessary to fill a certain amount of air into the big bag to open the bag, but because it is difficult to inflate the bag evenly, so It is also difficult to ensure that the expansion of the bag is uniform

[0004] At the same time, during the filling process of the material, the lower part of the ton bag is too inflated due to the backlog of material, and because the residual gas contained in the material cannot be discharged as soon as possible, the mixture of material and residual gas accumulates too high in the ton bag. It is very likely that the bag will be tilted or inverted, which will affect the stability of the big bag filling
