Description

Technical Field

[0001] The utility model relates to the technical field of exhaust devices for packaging machines, in particular to an automatic exhaust device for a valve bag packaging machine. Background Art

[0002] The automatic exhaust device of the valve bag packaging machine is an auxiliary equipment for valve bag packaging, which can pump and discharge the excess gas in the multi-valve bags. It is one of the indispensable accessories of the valve bag packaging machine.

[0003] For example, publication number CN217261155U discloses an automatic exhaust device for a valve bag packaging machine, whose structure includes a docking groove, an exhaust hood, a sealing plate, a frame, a driving machine, and a top connecting plate. The utility model provides an automatic exhaust device for a valve bag packaging machine, which is fixedly installed on the packaging machine through the docking groove on the top connecting plate, and the gas produced and processed can be discharged through the exhaust hood. When the gas is discharged, it will be uniformly delivered to the gas gathering groove through an elastic pipe, and will be dispersedly discharged through the six discharge cylinders on the exhaust groove. The discharged gas will blow the baffle on the support frame to discharge the gas. When the gas is stopped being discharged, the baffle will be reset under the influence of gravity to isolate the external dust. By improving the structure of the equipment, the exhaust device can better divert and discharge the gas when in use, reduce the exhaust pressure, and automatically close after the exhaust is completed to avoid back suction and adsorption of surrounding dust.

[0004] Based on the search of patent numbers and combined with the deficiencies in the prior art, it is found that:

[0005] Although the automatic exhaust device of this valve bag packaging machine can better divert and discharge gas, reduce the exhaust pressure, and automatically close after exhaust to avoid back-suction and adsorption of surrounding dust, during use, due to the adsorption of dust, a large amount of dust is easily attached to the surface of the baffle after long-term use. When the gas discharge blows the baffle to rotate, it is easy to cause some dust to fall to the opposite side of the baffle. The support frame responsible for fixing the baffle is fixedly installed inside the connecting shell, which is difficult for users to disassemble and clean. Therefore, this device has limitations when used. Utility Model Content
