Description

Technical Field

[0001] The present invention relates to the field of mechanical automation technology, and more specifically, to an airflow sequence distribution device. Background Art

[0002] At present, the existing patent CN211118186U discloses a distributor, including a hollow distribution main pipe with sealed ends; an air inlet is provided in the middle of one side of the distribution main pipe, and an air outlet is provided on the other side; a check valve is installed on the air inlet. The technical solution of the present application prevents water from entering the air source when the air source is suddenly powered off or fails, thereby protecting the air source and its pipeline structure; the integrated structure of the check valve and the distributor ensures the stability of the air path structure, and simplifies the device structure compared to the air path distribution structure in which check valves are respectively provided on multiple branch pipes.

[0003] However, the current gas distribution can only be distributed to different branches at the same time, and the order of distributing the pipelines cannot be selected in an orderly manner, so that some equipment that needs to use gas first cannot work first, and the pipelines that need to work first need to be reconnected to additional gas pipelines, thereby increasing costs. Summary of the invention

[0004] In view of this, the present invention proposes an air flow sequential distribution device, which includes: an air flow main pipe 10, a hollow chamber 20 is provided in the air flow main pipe 10, a closed cover body 30 is provided at one end of the air flow main pipe 10, an air inlet 40 is provided at the other end of the air flow main pipe 10, and a body of the air flow main pipe 10 is provided with a first air outlet 50 and a second air outlet 60, the first air outlet 50 and the second air outlet 60 are arranged front and back, the air inlet 40, the first air outlet 50 and the second air outlet 60 are all connected to the hollow chamber 20, and a compression member 70 is slidably connected in the hollow chamber 20, and in the initial state, the compression member 70 is located at the rear end of the first air outlet 50 or just at the first air outlet 50, thereby closing the first air outlet 50 and the second air outlet 60. When the air flow enters the hollow chamber 20 through the air inlet 40, pressure is applied to the compression member 70, and the compression member 70 slides along the hollow chamber 20. When the compression member 70 slides over the first air outlet 50, at this time, the first air outlet 50 is opened and the second air outlet 60 is closed, thereby providing corresponding air flow for the equipment connected to the first air outlet 50. When the compression member 70 slides over the second air outlet 60, at this time, the first air outlet 50 and the second air outlet 60 are both opened, forming a time difference, thereby providing corresponding air flow for the equipment connected to the first air outlet 50 and the second air outlet 60. The structure is simple, the cost is low, the reliability is high, and the control is precise.

[0006] Furthermore, a closed cover body 30 with a small hole 31 is provided at one end of the airflow main pipe 10. The small hole 31 is connected to the hollow chamber 20.

In the initial state, the compression element 70 is located at the first air outlet 50, so that the first air outlet 50 can be quickly opened when the air flows through the air inlet 40, thereby preventing the waste of air flow.

[0013] Furthermore, the first air outlet 50 and the second air outlet 60 are disposed vertically and staggered to facilitate connection of devices.

[0014] Furthermore, the diameter of the first air outlet 50 is different from the diameter of the second air outlet 60 , so that the air supply volume of the first air outlet 50 is different from the air supply volume of the second air outlet 60 , thereby adapting to various air supply volume requirements.

When the compression member 70 is compressed, it is used to discharge the air between the compression member 70 and the closed cover body 30 to reduce the resistance of the compression member 70 to slide forward. The hollow chamber 20 and the compression member 70 are cylindrical, so as to reduce the resistance of the compression member 70 to slide forward. The other end of the air flow main pipe 10 is provided with an air inlet 40, and the main body of the air flow main pipe 10 is provided with a first air outlet 50 and a second air outlet 60.

A compression piece 70 is slidably connected in the hollow chamber 20, and an elastic component 80 is provided between the compression piece 70 and the closed cover body 30.

[0023] In the initial state, the compression member 70 is located at the rear end of the first air outlet 50 or exactly at the first air outlet 50, thereby closing the first air outlet 50 and the second air outlet 60. When the air flow enters the hollow chamber 20 through the air inlet 40, pressure is applied to the compression member 70, and the compression member 70 slides along the hollow chamber 20.

When the compression member 70 slides over the second air outlet 60, at this time, the first air outlet 50 and the second air outlet 60 are both opened, forming a time difference, thereby providing a corresponding air flow for the devices connected to the first air outlet 50 and the second air outlet 60.

[0024] The first air outlet 50 is close to the air inlet 40. In the initial state, the compression element 70 is located at the first air outlet 50, so that the first air outlet 50 can be quickly opened when the air flows through the air inlet 40 to prevent waste of air flow. The first air outlet 50 and the second air outlet 60 are arranged up and down. After misalignment, it is convenient to connect the equipment. The diameter of the first air outlet 50 is different from the diameter of the second air outlet 60, so that the air supply volume of the first air outlet 50 is different from the air supply volume of the second air outlet 60, which is adapted to various air supply volume requirements. The air inlet 40, the first air outlet 50 and the second air outlet 60 are all provided with external air pipe connectors, which are convenient for quick disassembly and installation with the external air pipe.

The compressor 70 is located at the rear end of the first air outlet 50 or just at the first air outlet 50 in the initial state, so as to close the first air outlet 50 and the second air outlet 60. Through the sliding of the compressor 70, the device can open and close the air outlet in sequence to ensure that the airflow is distributed to different devices in a preset order, avoid uneven pressure or equipment conflict caused by simultaneous air supply, simplify the structure, and reduce costs. The airflow distribution is achieved only by the sliding of the compressor 70, and no complex electronic or mechanical control system is required. The structure is simple, maintenance is convenient, and manufacturing costs are reduced. The mechanical design reduces the use of electronic components, reduces the failure rate, and improves the stability and reliability of the system.
