Description

Technical Field

[0001] The utility model relates to the field of vacuuming, in particular to an automatic vacuuming platform. Background Art

[0002] The core function of the automatic vacuum platform is to remove air from packaging to extend the shelf life of food and other items. By reducing the contact between oxygen and food, the rate of deterioration is slowed down, thereby extending the shelf life of food. In certain production processes, such as bottle washing and semiconductor manufacturing, a vacuum machine is required to extract the gas in the enclosed space and reduce the pressure of the gas in the space to achieve the purpose of gas removal. In a vacuum state, since the oxygen is extracted, oxidation reactions in the air will hardly occur, which can effectively prevent oxidation and corrosion of metals and other materials.

[0003] After searching, Chinese patent announcement number: CN220909932U discloses an automatic vacuum platform. By setting multiple pneumatic baffle valves on both sides of the main pipeline, the platform can vacuum multiple vacuum components at the same time, and rely on the vacuum gauge and control box to automatically adjust the opening and closing of the ion pump and pneumatic baffle valve according to the vacuum degree, which improves work efficiency.

[0004] In the above technical solution, multiple vacuum components are vacuumed using multiple start-up baffle valves. When the module needs to be packaged, it is necessary to use vacuum to remove bubbles between the material and the interface. However, there is a lack of a function to fix and smooth the packaging film or packaging tape before vacuuming. When the packaging film or packaging tape is in a wrinkled state, there is a risk of air leakage at the interface, thereby affecting the vacuuming effect. Therefore, an automatic vacuuming platform is proposed to solve the above problem. Utility Model Content

[0033] Reference Figure 1 - Figure 3 A screw hole 5 is provided on the top of the slider 4, and the inner wall of the screw hole 5 is threadedly connected with a bolt 6, and the inner wall of the outer wall ear plate 7 of the bolt 6 is threadedly connected.

At the same time, manually pull the pull plate 9 upwards, and the limit spring 10 is compressed to make the slide bar 11 drive the positioning plate 12 to move upwards. When the position of the U-shaped frame 8 is not misaligned with the lower end of the packaging film opening, manually release the pull plate 9, and the positioning plate 12 loses its pulling force and moves downward. The two sets of pressing rollers 18 will contact the lower end of the packaging film opening. After being blocked by the placement platform 2, the two sets of pressing rollers 18 move upwards. When the film is rolled to the opposite side, the telescopic rod 24 and the telescopic spring 25 are stretched accordingly, and the two sets of mounting plates 17 are unfolded outward, and the two sets of pressing rollers 18 are rolled against the surface of the packaging film to press and smooth it. When the volume of the packaging film changes, the knob 13 is manually rotated forward or reverse, and the knob 13 drives the bidirectional screw rod 15 to rotate forward and reverse, so that the two sets of threaded blocks 16 drive the two sets of mounting plates 17 to move closer or farther away from each other. At this time, the guide block 20 slides inside the guide groove 19 to ensure the stability of the two sets of mounting plates 17 moving closer or farther away, thereby allowing the pressing roller 18 to adapt to packaging films of different sizes to press and smooth them before automatic vacuuming, thereby ensuring the vacuuming effect.
