Please refer to FIG. 1, FIG. 2 and FIG. 3, which are three-dimensional schematic diagrams, three-dimensional exploded schematic diagrams, and sectional structural schematic diagrams of the preferred embodiment of the creation. This creation is a composite vacuum cylinder. The vacuum cylinder 1 mainly includes: a cylinder housing 10, a first cylinder head 11, a second cylinder head 12, a vacuum suction pipe body 13, and a vacuum inner pipe 14, wherein two ends of the cylinder housing 10 are respectively provided The first cylinder head 11 and the second cylinder head 12, and the cylinder housing 10 define accommodation spaces 100 communicating with the first cylinder head 11 and the second cylinder head 12, respectively. The first cylinder head 11 is provided with a vacuum suction hole 110 and A first air inlet 112 is in communication with the accommodation space 100. The second cylinder head 12 is provided with an inlet and outlet 120 and a second air inlet 122 in communication with the accommodation space 100. The vacuum suction pipe 13 is disposed in the accommodation space 100 and is subject to the gas pressure of the first air inlet 112 and the second air inlet 122 to change the operating state in the accommodation space 100 to decide to extend toward the inlet and outlet 120 or Internally retracted, the vacuum inner tube 14 is disposed in the vacuum suction pipe body 13 and communicates with the vacuum suction hole 110 for the vacuum suction pipe body 13 to suck articles in a vacuum manner.

In addition, a piston structure 15 is further included, which is disposed at one end of the vacuum suction pipe body 13 and located in the accommodation space 100. A vacuum suction portion 130 is provided at one end of the vacuum suction tube body 13.

Furthermore, the aforementioned second cylinder head 12 is further provided with an air regulating valve 124, and the operating speed of the piston transport structure 15 can be adjusted by using the air regulating valve 124.

Referring to FIG. 4 and FIG. 5 together, the first operation state diagram and the second operation state diagram of the preferred embodiment of the present invention are shown. In FIG. 4, taking the air intake from the first cylinder head 11 as an example to prepare for suction, first, an external pressurizing device drives the air pressure from the first intake port 112 of the first cylinder head 11 (solid line arrow). At this time, The piston structure 15 located in the accommodating space 100 is pushed. Since the piston structure 15 is disposed at one end of the vacuum suction pipe body 13, when the piston structure 15 moves, the vacuum suction pipe body 13 is naturally driven toward the inlet and outlet 120 of the second cylinder head 12. Move and extend (solid line arrow). While moving, the vacuum suction hole 110 on the first cylinder head 11 is connected with an external vacuum equipment, and the vacuum is sucked through the vacuum inner tube 14 provided in the vacuum suction tube 13 A vacuum state (dashed arrow) is generated in the tube body 13.

After the vacuum suction pipe body 13 is removed from the inlet and outlet 120, the vacuum suction part 130 located on the vacuum suction pipe body 13 sucks the articles in a vacuum manner to reach a complete suction state. After the suction is completed, the first air intake of the first cylinder head 11 The inlet 112 stops the air intake, and the second inlet 122 of the second cylinder head 12 inputs the air pressure through the pressurizing device and pushes the piston structure 15 back so that the vacuum suction pipe 13 is retracted from the inlet and outlet 120 (solid line arrow) Then, the sucked articles are moved upward, and then the articles can be separated from the vacuum suction section 130 of the vacuum suction pipe body 13 after the external vacuum equipment is stopped.

The above-mentioned structural equipment can greatly improve the problem of requiring a large installation space, while simplifying the assembly process to improve assembly efficiency.

The above-mentioned embodiments are only for illustrative purposes to explain the principle of the creation and its effects, and are not intended to limit the creation. Anyone familiar with this technique can modify the above embodiments without departing from the spirit and scope of this creation. Therefore, the scope of protection of the rights of this creation shall be as listed in the scope of patent application mentioned later.
