[0019] Reference Figures 1 to 5 As shown, the utility model provides an intelligent laminating machine and bubble removal device, comprising: a laminating machine body 1 and a vacuum tube 5, wherein the front end of the laminating machine body 1 is connected to the vacuum tube 5.

[0020] The upper end frame of the plastic sealing body 1 is connected to the lifting plate 4 through a screw lifting mechanism 42. A stepping motor 44 is embedded and fixed inside the lifting plate 4. The lower end of the stepping motor 44 is connected to a rotating disk 41. The left and right sides of the rotating disk 41 are connected to the translation guide rails 31 through electric push rods 43. The lower end of the translation guide rail 31 is movably connected to the hot plastic sealing wheel 3 through a fixed frame 34. The outer end of the hot plastic sealing wheel 3 is provided with a heating surface 35, and the inner side of the heating surface 35 is installed with an electric heating wire 36. The pipe rack 52 is fixed to the tube surface of the vacuum tube 5, and the upper end of the pipe rack 52 is embedded and fixed with a proximity sensor 51.

[0021] First, the film-absorbing plate 2 absorbs the plastic film through the adsorption hole 23, and moves right to the adsorption net port 13 on the table of the plastic sealing machine body 1. The film-absorbing plate 2 disconnects the adsorption of the plastic film and resets it. Then, the article is placed on the film surface at the upper end of the plastic sealing machine body 1, and another roll of plastic film is manually pulled to cover the upper surface of the product. The electric push rod 43 is used to adjust the spacing of the heat-plastic sealing wheel 3 to exceed the size of the article, so that the wheel surface of the heat-plastic sealing wheel 3 is heated, and then the heat-plastic sealing wheel 3 is driven by the lifting plate 4 to move downward and contact the left and right side films of the film-coated article. The translation guide rail 31 drives the heat-plastic sealing wheel 3 to move horizontally backward The heat-sealing wheel 3 moves, causing the heat-sealing wheel 3 and the cutting blade 33 to seal and cut the left and right film ends of the coated article. The vacuum tube 5 is then inserted into the double-layer film to perform vacuuming, so that the plastic film is tightly attached to the surface of the article. At this time, the heat-sealing wheel 3 moves up and rotates 90 degrees counterclockwise, so that the heat-sealing wheel 3 is at the front and back sides. The heat-sealing wheel 3 is then lowered and driven to roll to the right. When the proximity sensor 51 detects the heat-sealing wheel 3 at a close distance, the pipe rack 52 drives the vacuum tube 5 to be pulled out of the film, so that the heat-sealing wheel 3 continues to roll and seal the previous plug-in position of the vacuum tube 5, and the film coating and plastic sealing process of the article is completed.

[0022] In this embodiment, two sets of film rolling rollers 11 are provided on the left side of the laminating machine body 1 ; film guide rollers are provided at the lower ends of the film rolling rollers 11 , and an electric slide 12 is installed on the rear side panel of the laminating machine body 1 .

[0023] As a preferred embodiment, a storage area is provided on the upper surface of the plastic sealing machine body 1, and the storage area is located on the left side of the adsorption mesh port 13, which is convenient for locating the placement of the items and preventing the items from deviating from the molding area and affecting the normal operation of the molding. Two sets of film rollers 11 are sleeved with two rolls of plastic film, and the two rolls of plastic film are distributed as the upper and lower film bodies for coating the items. When both layers of film are on the upper and lower surfaces of the items, plastic sealing, vacuuming and air bubble removal operations can be performed. The vacuum tube 5 is connected to the vacuum pump to facilitate vacuuming the double-layer film, expelling bubbles from the film surface while making the plastic film tightly adhere to the surface of the item, ensuring that the items are not subject to moisture, pollution and corrosion during transportation, and reducing the probability of damage to the items.

[0024] In this embodiment, the electric slide 12 is connected to a drive trough plate 25 via a slider, which is in turn connected to the film suction plate 2 via a first hydraulic ram 26 mounted on the upper surface of the drive trough plate 25. A small air pump 21 is secured to the left side of the film suction plate 2 and connected to the upper end of the film suction plate 2 via a negative pressure pipe 22. A rubber pad 24 is bonded to the lower surface of the film suction plate 2. Both the lower surface of the film suction plate 2 and the rubber pad 24 are provided with suction holes 23, which are in communication with the negative pressure pipe 22.

[0025] As a preferred embodiment, the driving groove plate 25 drives the film suction plate 2 to reciprocate left and right via the electric slide 12. After the cut plastic film is sucked and moved to the suction mesh port 13, the small air pump 21 pauses suction, allowing the film suction plate 2 to return to its original position. Then, negative pressure is applied through the suction holes 23 to suck the plastic film on the table, facilitating the automatic movement of the lower layer of plastic film to the appropriate position and improving the intelligence of the laminating machine 1. The first hydraulic column 26 is used to move the film suction plate 2 up and down to prevent the lower end surface of the film suction plate 2 from rubbing against the plastic film surface when the film suction plate 2 is reset, which could cause damage to the plastic film.

[0026] In this embodiment, a rectangular adsorption mesh port 13 is provided on the upper surface of the plastic packaging machine body 1 , and the front end of the pipe rack 52 is connected to the plastic packaging machine body 1 via a second hydraulic column 53 .

[0027] As a preferred embodiment, the adsorption mesh port 13 is used to adsorb the lower plastic film, so that the article to be coated is placed on the upper surface of the lower plastic film, and then the plastic film is pulled to cover the surface of the flat article to perform the plastic sealing operation. The second hydraulic column 53 is used to drive the vacuum tube 5 to be inserted into or removed from the double-layer plastic film. The short-range sensor 51 at the upper end of the pipe rack 52 conveniently senses the heat-sealing wheel 3 and determines whether the heat-sealing wheel 3 rolls to the insertion position of the vacuum tube 5 at a close distance, thereby driving the vacuum tube 5 to be quickly moved out by the second hydraulic column 53, so that the rolling heat-sealing wheel 3 will plastic-seal the insertion film port, which is convenient for shortening the connection time between the vacuuming and heat-sealing operations of the plastic sealing machine, speeding up the plastic sealing speed after removing the vacuum tube 5, ensuring the tightness of the film coating and plastic sealing of the plastic sealing machine, and improving the bubble removal effect of the plastic sealing film surface of the plastic sealing machine.

[0028] In this embodiment, the front and rear ends of the fixing frame 34 are symmetrically mounted with protective cover plates 32 ; the protective cover plates 32 are connected to the outer end of the thermoplastic sealing wheel 3 , and the lower end of the fixing frame 34 is screwed with a cutting blade 33 .

[0029] As a preferred embodiment, the protective cover plate 32 prevents humans from accidentally touching the heating surface 35 of the heat-plastic sealing wheel 3, thereby reducing safety hazards. The protective cover plate 32 also provides protection and dust-proofing, dissipating heat, and preventing the heat-plastic sealing wheel 3 from overheating and affecting the sealing effect. The cutting blade 33 follows the rolling and sealing motion of the heat-plastic sealing wheel 3 and simultaneously cuts the edge of the plastic film, facilitating simultaneous removal of excess film during plastic sealing, thereby enabling the laminator to cut off excess film material.

[0030] The intelligent laminating machine and bubble removal device of the utility model can effectively solve the problem in the prior art that the vacuum tube is pulled out before the laminating film is opened, which easily affects the vacuuming effect and causes bubbles to be generated on the laminating film surface. It is convenient to shorten the connection time between the vacuuming and hot laminating operation of the laminating machine, speed up the laminating speed after the vacuum tube is removed, ensure the tightness of the laminating film of the laminating machine, and improve the bubble removal effect on the laminating film surface of the laminating machine. It is suitable for intelligent laminating machines and bubble removal devices.
