Pipe feeding mechanism

Abstract

The invention discloses a pipe feeding mechanism suitable for long-distance feeding and high feeding. The pipe feeding mechanism comprises a first feeding pipe and a second feeding pipe which are hollowed internally, an adjusting pipe and a transfer pipe, wherein the outer end of the adjusting pipe is connected to the first feeding pipe, and the outer end of the transfer pipe is connected to the second feeding pipe. The adjusting pipe is internally provided with a first air conveying channel. An air supply pipe is arranged outside the transfer pipe. The transfer pipe is internally provided with a second air conveying channel. The inner end of the transfer pipe is internally provided with an air flue reversing opening extending in the direction from the air supply pipe to the second air conveying channel. A gap and a third air conveying channel are formed between the inner circumferential face of the air flue reversing opening and the outer circumferential face of the inner end of the adjusting pipe. When the air conveying pipe conveys air through the third air conveying channel, air in the first air conveying channel and air in the third air conveying channel are mixed and flow towards the interior of the second air conveying channel, and a workpiece located in the first feeding pipe is moved into the second feeding pipe.

Description

technical field [0001] The invention relates to an automatic conveying device for small parts of automatic equipment. Background technique [0002] In the existing automatic production line, long-distance and high-height automatic feeding mechanisms for small-volume metal or non-metal materials are often used, such as steel balls, rollers, positioning pins, needle rollers, screws, nuts and other parts. The device of the present invention uses the blowing force generated by the compressed air to transport the parts over a long distance or to a high place during work. However, the transmission accuracy of the existing device is still insufficient, resulting in low working accuracy. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the object of the present invention is to provide a pipeline feeding mechanism with compact structure and high transmission precision. [0004] In order to achieve the above object, the present inventi...

[0002] In the existing automatic production line, long-distance and high-height automatic feeding mechanisms for small-volume metal or non-metal materials are often used, such as steel balls, rollers, positioning pins, needle rollers, screws, nuts and other parts. The device uses the blowing force generated by the compressed air to transport the parts for a long distance or to a high place when it is working. However, the transmission accuracy of the existing device is still insufficient, resulting in low working accuracy.
