DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figure 1 and Figure 2 The present application provides a technical solution: an air guide structure of a filter element pneumatic marking machine, comprising a base 1, the upper surface of the base 1 is provided with an air cylinder 14, the movable end of the air cylinder 14 is provided with a moving seat 3, one side of the upper surface of the base 1 is provided with a support plate 2, one side of the support plate 2 facing the moving seat 3 is provided with two vertically arranged linear guide rails 6, the sliding seat 4 is slidably connected to the linear guide rails 6, the sliding seat 4 is fixedly connected with the moving seat 3, the linear guide rails 6 and the sliding seat 4 are matched with each other to limit the moving track of the moving seat 3 and improve the stability of the structure.

[0024] Please refer to Figure 1 and Figure 2The upper side of the movable base 3 is provided with an arc-shaped plate 7 for supporting the filter element. A connecting plate 5 is fixedly connected to the lower surface of the arc-shaped plate 7, and the connecting plate 5 is connected to the movable base 3 by multiple screws to complete the assembly of the arc-shaped plate 7 and the movable base 3. A pressure seat 8 is provided directly above the arc-shaped plate 7 and directly below the pneumatic marking head. One end of the pressure seat 8 is connected and fixed to the support plate 2. An upper rectangular opening 10 is opened on the upper surface of the pressure seat 8. A buffer seat 12 is provided directly below the pressure seat 8. A lower rectangular opening 18 is opened on the upper surface of the buffer seat 12 to match the upper rectangular opening 10. Small holes are opened at the four corners of the upper surface of the buffer seat 12. Each corner has an upper small hole aligned with the lower small hole. A long screw 9 is inserted into the channel formed by the lower small hole and the corresponding upper small hole. The lower end of the long screw 9 is threaded with a limit nut 17. A spring 11 is fitted on the long screw 9 between the pressure seat 8 and the buffer seat 12. The filter element is placed in the arc plate 7, and then the cylinder 14 is extended. Under the guidance of the interaction between the linear guide rail 6 and the slide 4, the arc plate 7 moves upward. At this time, the filter element in the arc plate 7 will squeeze the buffer seat 12, and the distance between the buffer seat 12 and the pressure seat 8 will shorten, so that the spring 11 is in a compressed state, realizing the flexible compression of the filter element.

[0025] See Figures 1-5 Multiple circular openings 22 arranged equidistantly in a ring are installed at both ends of the arc-shaped plate 7, allowing one end of the sleeve 15 to be installed inside the circular openings 22, completing the assembly of the sleeve 15 and the arc-shaped plate 7. A circular nut 21 is installed on the side of the sleeve 15 away from the arc-shaped plate 7. A long screw 16 for supporting the filter element is internally threaded onto the circular nut 21. The long screw 16 is arranged along the radial direction of the arc-shaped plate 7. A rubber head 19 is glued to the end of the long screw 16 away from the shielding sleeve 13. The diameter of the rubber head 19 is the same as the diameter of the long screw 16, allowing for flexible contact between the long screw 16 and the filter element. A knob head, integrally formed with the long screw 16, is installed on the end of the long screw 16 away from the rubber head 19. A shielding sleeve 13 is fitted onto the sleeve 15, making sliding contact with the sleeve 15. The shielding sleeve 13 is fitted onto the long screw 16 and connected and fixed to it. A rubber plug 20 is provided on one side facing the center area of ​​the arc plate 7. The rubber plug 20 is slidably installed inside the sleeve 15. The rubber plug 20 is sleeved on the long screw 16 and connected and fixed to the long screw 16. The threaded connection between the long screw 16 and the round nut 21 is hidden in the space formed by the sleeve 15, the rubber plug 20 and the shielding sleeve 13. This prevents foreign objects from entering the threaded connection between the long screw 16 and the round nut 21 and affecting the turning of the long screw 16. The long screw 16 is rotated according to the diameter of the filter element, so that the length of the long screw 16 inside the arc plate 7 increases. At this time, the long screw 16 drives the shielding sleeve 13 to slide relative to the sleeve 15. Then, the multiple long screws 16 at both ends of the arc plate 7 together form a structure for supporting the filter element, which facilitates the support of filter elements with smaller diameters without the need to replace arc plates 7 of different specifications, thus improving the convenience of use.
