Air floating and pulse type automatic quantitative valve bag packing machine

Abstract

The invention discloses an air floating and pulse type automatic quantitative valve bag packing machine. The packing machine comprises a tank body, a ventilating plate, a sealing cover and an air storage tank; the top of the tank body is provided with a butterfly valve, the side wall of the tank body is provided with a discharge opening, an inclined opening is formed in the bottom of the tank body, the ventilating plate is arranged on the inclined opening through a flange assembly, and the sealing cover is arranged under the ventilating plate and is connected with the flange assembly; compressed air is stored in the air storage tank, and the air storage tank communicates with the sealing cover through an air floating air pressure pipe and a pulse air pressure pipe; and the pulse air pressure pipe is provided with a pulse valve, an electromagnetic valve and a pressure regulating valve are arranged on the air floating air pressure pipe, and the pulse valve and the electromagnetic valve are synchronously arranged. The ventilating plate is convenient to clean and replace, the compressed air in the air storage tank is used for applying pulse compressed air and air floating compressed air to to-be-packaged materials in the tank body through the ventilating plate, the pulse compressed air is closed after one pulse is completed, the air floating compressed air continues to be applied so that air floating air flows can be kept on the ventilating plate, the friction between the materials and the ventilating plate can be reduced, the packaging precision can be improved, and dust pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of packaging machines, in particular to an air-floating pulse automatic quantitative valve pocket packaging machine. Background technique [0002] In the existing packaging machine, it is difficult to replace the entire air flotation plate fixed on the air flotation chamber with strong glue. There is a gap between the air flotation device and the tank body, which is easy to run ash. The body edge source pulsed air cannot be blown by the compressed air, and the air flotation device and the tank form a dead angle. At the end of a pulse, due to the closing of the solenoid valve, the air flotation plate loses air flow, and the material returns to the air flotation plate by its own weight. Repeat this, resulting in For the wear of the air flotation plate, after one pulse ends, the material returns to the air flotation plate. When the pulse continues to circulate, the impact force is large, and it is easy to run o...

Problems solved by technology

[0002] In the existing packaging machine, it is difficult to replace the entire air flotation board with super glue on the air flotation chamber. There is a gap between the air flotation device and the tank body, which is easy to run dust. The side source pulse gas compressed air cannot blow, and the air flotation device and the tank form a dead angle. At the end of a pulse, because the solenoid valve is closed, the air flotation plate loses air flow, and the material returns to the air flotation plate by its own weight. Repeat this, resulting in For the wear of the air floating plate, after one pulse ends, the material returns to the air floating plate. When the pulse continues to circulate, the impact force is large, and it is easy to run ash, which affects the smoothness of the discharge and the packaging accuracy.
