Description

Technical Field

[0001] The present application relates to the field of material conveying equipment, and in particular to an automatic suction gun. Background Art

[0002] Some industries often need to use powder and granular materials due to work needs. Powders are usually packaged in bags and barrels. In order to ensure the quality of the powder, the barrel has an independent inner packaging bag in the barrel. In actual use, there are usually two ways of feeding. One is to pour the material out by manually carrying the packaging bag, and the other is to insert the suction cavity into the material. The suction gun is connected to the vacuum feeder through the suction pipe, and the material is sucked into the corresponding equipment through the negative pressure pneumatic conveying system.

[0003] In the related art, in order to facilitate work, a suction gun is usually used to transport materials. When the material needs to be transported, first, the personnel places the material under the suction gun. At this time, the suction gun is close to the material, and then the suction gun is turned on. The suction gun can transport the material to the corresponding equipment.

[0004] With respect to the above-mentioned related technologies, the material can be transported to the corresponding equipment through the suction gun, but during the operation of the suction gun, negative pressure is generated inside the suction gun. When the suction gun sucks the material, dust in the air may be sucked into the material, resulting in dust mixed in the material. Utility Model Content
