A suction device for a vacuum feeder

Abstract

The invention discloses a suction device of a vacuum feeding machine. The suction device comprises an external gun, an internal gun, a connection sleeve, locking studs and a cylindrical pin, wherein the external gun comprises an external gun tube, a gun grip and a gun tip, the internal gun comprises an internal gun tube and a stop, two threaded holes are formed in the outer wall of the connection sleeve, at least one hole matched with an air hole of the external gun tube is formed in the outer periphery between the two threaded holes, the locking studs comprise a first locking stud and a second locking stud, and the cylindrical pin is embedded into the connection sleeve. The suction device has a simple structure, works stably, and is free of phenomena of blocking a suction device by powder during vacuum feeding and frequent manual operation, suction is not influenced no matter the suction device is buried in a material pile deep or not, and the size of suction can be adjusted by the suction device, so that the service efficiency of the vacuum feeding machine can be improved, and the use is convenient.

Description

technical field [0001] The invention belongs to the field of feeding machinery, and in particular relates to a simple suction device applied to a vacuum feeding machine for conveying powder and granules. Background technique [0002] Vacuum feeder is a dust-free airtight pipeline conveying equipment that uses vacuum suction to convey granular and powdery materials. It utilizes the air pressure difference between the vacuum and the ambient space to form gas flow in the pipeline and drive the powdery materials to move, thus completing the process. Powder transportation. This transportation method can prevent dust pollution, improve the working environment, reduce the pollution of the environment and personnel to materials, and improve the cleanliness; because it is pipeline transportation, it occupies a small space, and can complete the powder transportation in a small space, making the space of the work room Beautiful and generous. Therefore, it is widely used in the transm...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the deficiency of the prior art: the powder inserted too deep blocks the material suction device, resulting in the phenomenon that the air in the conveying pipeline does not circulate and cannot absorb the material, while the insertion is too shallow, the material is easy to be sucked, and multiple manual operations are required. And developed a simple vacuum feeding machine suction device, simple structure, stable work, can solve the phenomenon of powder blocking the suction device and multiple manual operations, and can use the suction device to adjust the suction, easy to use, improve vacuum Loading machine usage efficiency
