[0030] Further, a sealing ring 24 is installed on the edge of the bottom surface of the vacuum cover 20, the sealing ring 24 is a rubber sealing ring with a thickness of 2-7mm, so that a good seal can be formed between the vacuum cover 20 and the workbench 10, effectively preventing external air from entering during the vacuum process, ensuring the effect of vacuuming, and further improving the sealing performance and quality of the dust-free cloth packaging.

[0031] Specifically, a lifting cylinder 30 is installed on the top of the vacuum cover 20, a lower sealing strip 15 is installed on the top surface of the workbench 10, and an upper sealing strip 22 is installed in the vacuum cover 20 and parallel to the lower sealing strip 15 and located in the same vertical plane, so that after the vacuuming is completed, the upper sealing strip 22 can be driven by the lifting cylinder 30 to move downward and cooperate with the lower sealing strip 15 to realize the sealing operation of the dust-free cloth packaging and improve the automation degree and efficiency of the packaging.

[0032] In addition, the piston rod 31 of the lifting cylinder 30 is connected to the upper sealing strip 22 at the bottom, and two groups of guide rods 23 are symmetrically arranged at both ends of the upper sealing strip 22, the guide rods 23 are inserted and matched with the vacuum cover 20 in interference fit, so that when the upper sealing strip 22 moves up and down under the driving of the piston rod 31 of the lifting cylinder 30, it can move smoothly along the direction of the guide rod 23, ensuring that the upper sealing strip 22 accurately docks and seals with the lower sealing strip 15, and improving the sealing quality and stability.

[0033] The working principle of the vacuum structure of the dust-free cloth packaging machine:

[0034] When using the vacuum structure of the cleanroom cloth packaging machine, first place the cleanroom cloth to be packaged on the workbench 10; start the lifting hydraulic cylinder 11, and its lifting rod 12 drives the workbench 10 to descend, so that the workbench 10 connected to the side ears 21 on both sides of the vacuum cover 20 approaches the vacuum cover 20, until the sealing ring 24 at the bottom edge of the vacuum cover 20 is tightly fitted with the workbench 10 to form a sealed space.

[0035] Next, as Figure 3 As shown, turn on the vacuum pump 40 so that the pumping end of the vacuum pump 40 can perform a vacuuming operation on the sealed space through the vent 13 to ensure the vacuuming effect.

[0036] After vacuuming is completed, the lifting cylinder 30 is activated, and its piston rod 31 pushes the upper sealing strip 22 to move downward along the guide rod 23. The upper sealing strip 22 cooperates with the lower sealing strip 15 on the top surface of the workbench 10 to seal the packaging. Since the guide rod 23 and the vacuum cover 20 are interference-fitted, the stability and accuracy of the movement of the upper sealing strip 22 are ensured.

[0037] After sealing, adjust the air inlet 16 to connect with the vent 13 using the three-way control valve 14, such as... Figure 4 As shown, the air pressure inside and outside the vacuum hood 20 is the same, and the lifting hydraulic cylinder 11 drives the worktable 10 to rise, take out the packaged cleanroom cloth, and complete one packaging process; this cycle is repeated to achieve efficient and sealed packaging of cleanroom cloth.
