[0023] As shown in Figures 1-3 The embodiment provides a floating butt joint device of a vacuum pipeline, which comprises a rack, a first vacuum pipeline body 1 connected to the rack through a translation guide assembly and an elastic assembly, one end of the first vacuum pipeline body connected to a vacuum pump 3 through a hose 2, and the other end of the first vacuum pipeline body coaxially connected to a movable second vacuum pipeline body 4, the second vacuum pipeline body fixedly connected to a movable box body 5, and the translation direction of the movable box body parallel to the translation direction of the first vacuum pipeline body.

[0024] The hose of the floating butt joint device of the vacuum pipeline does not move along with the reciprocating translation of the movable box body, and when the movable box body needs to be vacuumized at a fixed position, the first and second vacuum pipeline bodies only need to be connected at the fixed position, and the first and second vacuum pipeline bodies are disconnected when the movable box body is away from the fixed position, so that the problems of bending and breaking of the vacuum hose caused by the reciprocating movement of the movable box body are solved.

[0025] In the embodiment of the utility model, the elastic assembly is arranged in the translation direction of the first vacuum pipeline body, one end of the elastic assembly is connected to a fixed end, and the other end of the elastic assembly is connected to the first vacuum pipeline body, so that the translation of the first vacuum pipeline body is elastically buffered.

[0026] In the embodiment of the utility model, the translation guide assembly comprises a fixed seat 6 fixedly connected to the rack, a guide rail 7 fixedly connected to the fixed seat, a sliding block 8 arranged on the guide rail, and the sliding block fixedly connected to the lower side of the first vacuum pipeline body.

[0027] In the embodiment of the utility model, the elastic assembly is a spring 10, one end of the spring fixedly connected to a fixed end on the rack, and the other end of the spring fixedly connected to the sliding block.

[0028] In the embodiment of the utility model, one end of the first vacuum pipeline body is connected to a tee joint 11, the end of the tee joint used for connecting the hose is a rear end, and the remaining end is a side end.

[0029] In the embodiment of the utility model, the rear end is first connected to a switch control valve 12, and the switch control valve is further connected to the hose.

[0030] In this embodiment of the utility model, a flow control valve 13 is connected to the side end.

[0031] The first vacuum tube, the tee joint, the flow control valve, and the switch control valve are locked together by pipe threads.

[0032] In this embodiment of the present invention, a sealing silicone strip 14 is fixedly provided on the end of the second vacuum tube body used to connect to the first vacuum tube body.

[0033] In this embodiment of the invention, the second vacuum tube is fixedly connected to the movable box via a bent tube 15 and communicates with the interior of the movable box.

[0034] In this embodiment of the utility model, a slider slide rail moving pair 9 is connected between the movable box and the frame.

[0035] In this embodiment of the invention, the first vacuum tube is a fixed connecting flange, and the second vacuum tube is a movable connecting flange.

[0036] In this embodiment of the invention, the working principle of the floating docking device for the vacuum pipeline is as follows:

[0037] like Figures 1-2 As shown, when the movable housing reciprocates between position one and position two, a vacuum only needs to be applied to the movable housing at position two; the movable housing does not need to maintain a vacuum state at other positions. When the movable housing starts moving from position one and is about to reach position two, the sealing silicone strip on the second vacuum tube first contacts the first vacuum tube, forming a seal on the pipeline. At this time, the vacuum pump is activated to evacuate the pipeline and the movable housing. As the movable housing continues to approach position two, the entire component on the slider (first vacuum tube, tee connector, switch control valve, diverter control valve, hose) is pushed together by the sealing silicone strip to move appropriately, while the spring is compressed by the slider. During this process, the spring, on the one hand, maintains the sealing pressure of the contact surface by keeping the sealing silicone strip in contact with the first vacuum tube through its reaction force; on the other hand, the spring compression provides a buffering effect on the entire movable housing component, reducing impact. When the movable housing moves from position two to position one, the second vacuum tube separates from the first vacuum tube, and the spring returns to its original position, pushing the slider and its fixed components back to their original positions.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
