Problems solved by technology
Although this jet vacuum generator achieves the purpose of saving gas to a certain extent, it still uses the traditional vacuum generating device to generate vacuum, which still consumes a large amount of compressed gas during the working process, and only has the function of vacuum generation, vacuum suction and vacuum release. Another device is needed to solve the problem, and the structure is bloated and complicated

Embodiment Construction
[0035] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.
[0036] The idea of the present invention is to generate an initial vacuum by pressing down the piston to discharge the air in the vacuum cylinder and the suction cup, and maintain the vacuum state during the suction process by the self-weight of the object to be sucked. When the vacuum degree in the vacuum cylinder cannot meet the suction requirements, the The auxiliary vacuum generation function is automatically turned on, so as to realize the safe and reliable suction of the device.
[0037] combine Figure 1-9, a gas-saving expansion type vacuum generation and suction integrated device, including expansion type vacuum generation element and three pneumatic circuits, wherein the expansion type vacuum generation element is divided into upper, middle and lower parts, the upper part is the vacuum generation and maintenance structure, and the middle ...

The invention discloses a gas-saving type volume-expansion vacuum generating and sucking integrated device and an operating method thereof. The upper part of the device is of a vacuum generating and maintaining structure, the middle part of the device is of a gas drainage structure, and the bottom part of the device is of a vacuum sucking structure; the vacuum generating and maintaining structureincludes a pressure spring structure and a cylinder vacuum containing cavity structure; the cylinder vacuum containing cavity structure includes a proximity switch, an upper end cover, a lower end cover, a vacuum cylinder, a piston rod and a piston; a proximity switch mounting port, a filter port and a piston rod mounting port are formed in the upper end cover; the proximity switch is fixedly arranged in the proximity switch mounting port and extends into the vacuum cylinder; the lower end of the piston rod is fixedly connected with the piston; the pressure spring structure is arranged at theouter side, located outside the vacuum cylinder, of the piston rod in a sleeving manner; the gas drainage structure includes a connecting sleeve, a vacuum release one-way valve and an auxiliary vacuumgenerating one-way valve; and the vacuum sucking structure is arranged under the gas drainage structure. The device has a vacuum generating function, a vacuum sucking function, a vacuum maintaining function and a vacuum release function, and is comprehensive in function, simple in structure and low in gas consumption.
Description
technical field [0001] The invention relates to the field of vacuum air material handling, in particular to a gas-saving expansion-type vacuum generation and suction integrated device and a working method thereof. Background technique [0002] Vacuum suction technology is a very easy-to-master transfer technology and a very reliable assistive technology. The use of vacuum technology for adjustment, control and monitoring can effectively improve the packaging and transportation efficiency of workpieces and parts under automatic, semi-automatic and manual working conditions. However, during the working process of the current vacuum suction device, a large amount of compressed gas is consumed during the vacuum generation and maintenance stages, and this part accounts for a large proportion of the total cost. [0003] Chinese patent 200610040832.1 discloses "a flow self-adjusting jet vacuum generator". The vacuum generator integrates an automatic flow adjustment part. When the ...
