[0021] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0022] Embodiment 1:

[0023] like Figures 1 to 4 As shown, this embodiment provides a pneumatic door sealing device for a cleaning machine, including a hatch 1 and a hatch 3, slide rails 2 are arranged on both sides of the hatch 3, and four track wheels 101 are symmetrically arranged at the bottom of the hatch 1, so that the hatch 1 can move along the slide rails 2 through the track wheels 101 and cover the hatch 3.

[0024] The slide rail 2 is provided with grooves 201 corresponding to the number of track wheels 101. When the hatch 1 is covered on the hatch 3, the track wheels 101 just fall into the grooves 201, thereby reducing the distance between the hatch 1 and the hatch 3, and then pressing the hatch 1 downward; the main body of the hatch 1 is made of aluminum alloy, and after being pressed down, the hatch 1 is in close contact with the sealing ring 301 provided on the hatch 3 by virtue of its own weight, thereby improving the sealing effect of the hatch 1 on the hatch 3.

[0025] It also includes a main cylinder 4, the piston rod end of the main cylinder 4 is hinged to the top surface of the hatch 1, the cylinder body of the main cylinder 4 is hinged to the fixing device 5, and the fixing device 5 is connected to the external mounting surface to fix the position of the main cylinder 4. The hatch 1 is driven by the piston rod of the main cylinder 4, so that the hatch 1 is translated along the slide rail 2; when the hatch 1 is pressed down, the hinges at both ends of the main cylinder 4 rotate naturally to adapt to the position change of the hatch 1.

[0026] The side wall of the groove 201 close to the main cylinder 4 is an inclined surface, and the angle between the inclined surface and the plane where the slide rail 2 is located is an acute angle, which facilitates the track wheel 101 to enter and exit the groove 201.

[0027] The working method of this embodiment is as follows:

[0028] When closing the door, the piston rod of the main cylinder 4 extends, driving the hatch door 1 to move horizontally along the slide rail 2 to the hatch opening 3, and the track wheel 101 at the bottom of the hatch door 1 falls from the slope of the groove 201 into the corresponding groove 201, thereby pressing the hatch door 1 downward. After being pressed downward, the hatch door 1 is in close contact with the sealing ring 301 provided on the hatch opening 3, thereby improving the sealing effect.

[0029] When opening the door, the piston rod of the main cylinder 4 contracts, the track wheel 101 returns to the normal slide rail 2 along the slope of the groove 201, and the hatch 1 moves away from the hatch 3 after translation along the slide rail 2, thereby achieving the effect of opening the hatch 3.

[0030] The master cylinder 4 in this embodiment is controlled by PLC programming.

[0031] Embodiment 2:

[0032] like Figures 5 to 7 As shown, this embodiment is an optimized solution of the first embodiment, and the sealing performance is further improved by the auxiliary pressing mechanism 6.

[0033] An auxiliary clamping mechanism 6 is provided on each side of the door 1 .

[0034] The two auxiliary clamping mechanisms 6 are symmetrical in structure, including a base 602, an auxiliary cylinder 601, and a connecting frame 603; an auxiliary cylinder 601 is arranged on the base 602, and the end of the piston rod of the auxiliary cylinder 601 is arranged away from the base; a slide groove 606 is arranged at the bottom of the base 602, and the slide groove 606 forms a sliding pair with the slide rail 2.

[0035] One end of the connecting frame 603 is fixedly connected to the top of the hatch 1, and the other end of the connecting frame 603 is provided with a sleeve 605, which is sleeved on the piston rod of the auxiliary cylinder 601 and slidably connected to the piston rod. A pressure head 604 is provided at the end of the piston rod of the auxiliary cylinder 601, and the bottom of the pressure head 604 is in contact and connected with the top of the sleeve 605.

[0036] The working method of this embodiment is as follows:

[0037] When the cabin door 1 moves on the slide rail 2 , the connecting frame 603 fixed to the cabin door 1 drives the entire auxiliary clamping mechanism 6 to move synchronously on the slide rail 2 through the slide groove 606 .

[0038] After the hatch 1 is covered on the hatch 3, the piston rod of the auxiliary cylinder 601 contracts, and the pressure head 604 on the piston rod is pressed downward, thereby driving the sleeve 605 to be pressed downward. The sleeve 605 drives the hatch 1 to be further pressed downward through the connecting frame 603, so that the hatch 1 and the sealing ring 301 on the hatch 3 are in closer contact, thereby further improving the sealing effect of the hatch 1 and the hatch 3. The high friction between the sealing ring 301 and the hatch 1 also achieves a locking effect.

[0039] When the hatch door 1 is opened, the piston rod of the auxiliary cylinder 601 is extended to release the lock, and then the hatch door 1 is opened according to the steps described in the first embodiment.

[0040] In this embodiment, the main cylinder 4 and the auxiliary cylinder 601 are controlled by PLC programming.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
