The outer surface of the support rod 15 is fixedly connected to an unwinding roller 16. The winding roller 14 and the unwinding roller 16 are both located above the conveyor belt 9.

[0036] In this embodiment, when the laminating device is used to process food packaging bags, the packaging bags are sent from the left side of the outer frame 1 to the top of the conveyor belt 9. After the first motor 2 is running, it can drive the conveyor belt 9 to operate. At this time, the rotation of the conveyor belt 9 can drive the packaging bags to move toward the support component 4 and the laminating component 5. After moving to the lower position, the first motor 2 controls the conveyor belt 9 to stop running. At this time, the packaging bags are in the upper position of the conveyor belt 9 and are in a flat adsorption state. The first electric push rod 402 is started to drive the support plate 403 to move downward, and the laminating component 5 is driven to move downward close to the packaging bag position for laminating processing. The fixed rod 503 can drive the connecting seat 505, the first support shaft 506 and the first roller 507 to follow through the connection with the outer frame 504. The first roller 507 moves downward, at this time, the first roller 507 can move downward to a state of fitting the conveyor belt 9. At this time, the packaging bag is in a state of being laid flat on the surface of the conveyor belt 9, and at the same time, a film with an adhesive attached to the bottom is wound around the unwinding roller 16, and the other end of the film is wound around the winding roller 14. Therefore, before the first electric push rod 402 runs, the film is between the packaging bag and the first roller 507. After the first roller 507 moves downward, it can press the film between the unwinding roller 16 and the winding roller 14 down to the surface of the packaging bag. At this time, the film, the packaging bag and the conveyor belt 9 are in a state of close fitting. Subsequently, the third electric push rod 502 is started to run and drive the blade 527 to move downward. After the blade 527 moves down to the surface of the film, the third electric push rod 502 is operated to slightly apply The pressure can cut the film into the corresponding fitting shape. After the cutting of the film is completed, the third electric push rod 502 contracts and drives the blade 527 to move up and reset.

When the air outlet hood 515 moves, the second roller 517 will be in a state of fitting the surface of the film.

[0037] Embodiment 2

[0038] Figure 4 As shown, a plurality of ventilation grooves 10 are evenly opened on the outer surface of the conveyor belt 9, a mounting seat 11 is fixedly connected to the inner surface of the outer frame 1, the mounting seat 11 is located on the inner side of the conveyor belt 9, and a plurality of fans 12 are evenly and fixedly connected inside the mounting seat 11, and the fans 12 are in a state of sucking air from top to bottom.

[0039] In the present embodiment, while the packaging bag is being processed at the lower position of the laminating component 5, the fan 12 is started. After the fan 12 is running, air can be blown downward, thereby generating suction from the upper position of the mounting seat 11. Since the mounting seat 11 is located on the inner side of the conveyor belt 9, and the plurality of air permeable grooves 10 are provided on the surface of the conveyor belt 9, the provision of the air permeable grooves 10 makes the surface of the conveyor belt 9 in a breathable state. At this time, the suction force generated by the operation of the fan 12 can make the packaging bag fit tightly to the surface position of the conveyor belt 9, ensuring that the packaging bag is in a relatively flat state during the laminating process, thereby avoiding displacement of the packaging bag during processing or wrinkles on the surface that affect the laminating quality.

[0040] Embodiment 3

[0041] Figure 6 and Fig. 9 As shown, an air outlet hood 515 is fixedly connected to the bottom of the air outlet pipe 514, and the air outlet hood 515 is connected to the connecting pipe 513. A heat pump 518 is fixedly connected to the outer surface of the sliding seat 512, and an air supply pipe 519 is fixedly connected to the output end of the heat pump 518. The air supply pipe 519 is fixedly connected to the connecting pipe 513. The inner surface of the air outlet hood 515 is symmetrically rotatably connected to a second support shaft 516, and the outer surface of the second support shaft 516 is fixedly connected to a second roller 517.

[0042] In this embodiment, as the air outlet hood 515 continues to move, hot air is sprayed onto the surface of the film, and the rotation of the second roller 517 rolls the film, so that the film and the packaging bag fit more closely, and the adhesive can be evenly covered on the surface of the packaging bag to complete the bonding, effectively improving the quality of the lamination process.

[0043] The use method and working principle of this device: When the laminating device is used to process food packaging bags, the packaging bags can be transported by using the conveyor belt 9 inside the outer frame 1. When the packaging bags are transported and laminating, the packaging bags are sent from the left side of the outer frame 1 to the top of the conveyor belt 9. When the packaging bags are placed, ensure that the packaging bags are in the center. At this time, start the first motor 2. After the first motor 2 is running, it can drive the driving roller 7 to follow the rotation. When the driving roller 7 is running, the driving roller 7 and the supporting roller 8 on the other side can synchronously drive the conveyor belt 9 to operate. At this time, the rotation of the conveyor belt 9 can drive the packaging bags to move toward the support component 4 and the laminating component 5. After moving to the position below them, , the first motor 2 controls the conveyor belt 9 to stop running, at this time, the packaging bag in a stationary state can be laminated, and while the packaging bag is being processed at the lower position of the laminating component 5, the fan 12 is started, and after the fan 12 is running, air can be blown downward, so that suction can be generated from the upper position of the mounting seat 11. Since the mounting seat 11 is located on the inner side of the conveyor belt 9, and at the same time, the plurality of air permeable grooves 10 on the surface of the conveyor belt 9 are arranged, the arrangement of the air permeable grooves 10 makes the surface of the conveyor belt 9 in a breathable state. At this time, the suction force generated by the operation of the fan 12 can make the packaging bag fit closely to the surface position of the conveyor belt 9, ensuring that the packaging bag is in a relatively flat state during the laminating process, and avoiding the position deviation of the packaging bag or the appearance of wrinkles on the surface during processing to affect the laminating. The packaging bag is in a state of flattening and adsorbing at this time. The first electric push rod 402 is started to run. After the first electric push rod 402 runs and stretches, it can drive the support plate 403 to move downward. Through the downward movement of the support plate 403, the laminating component 5 can be driven to move downward close to the packaging bag position for laminating processing. When the support plate 403 is driven to displace by the first electric push rod 402, the support plate 403 will move along the slide rail 6 through the connection of the slider 405. At this time, the cooperation of the slide rail 6 and the slider 405 plays a role of supporting and limiting the movement of the support plate 403. After the second electric push rod 501, the third electric push rod 502 and the fixed rod 503 are driven downward by the operation of the first electric push rod 402, the fixed rod 503 can drive the connecting seat 505, the first support shaft 506 and the first roller 507 to move downward through the connection of the outer frame 504. At this time, the first roller 507 can move downward to fit the conveyor belt 9. At this time, the packaging bag is in a state of being laid flat on the surface of the conveyor belt 9, and at the same time, a film with an adhesive attached to the bottom is wound around the unwinding roller 16, and the other end of the film is wound around the winding roller 14. Therefore, before the first electric push rod 402 runs, the film is between the packaging bag and the first roller 507. After the first roller 507 moves downward, it can press the film between the unwinding roller 16 and the winding roller 14 to the surface of the packaging bag. At this time, the film, the packaging bag and the conveyor belt 9 are in a state of close contact, and then the third electric push rod 502 is started to run.After the third electric push rod 502 is extended, it can drive the blade 527 to move downward through the connection with the fixed frame 526. The blade 527 is in a rectangular state, which is consistent with the shape of the film that needs to be attached to the surface of the packaging bag. Therefore, after the blade 527 moves down to the position on the surface of the film, the third electric push rod 502 operates and slightly applies pressure to cut the film into the corresponding fitting shape. After the cutting of the film is completed, the third electric push rod 502 contracts and drives the blade 527 to move up and reset, and then the second electric push rod 501 is started to run. After the second electric push rod 501 is extended and runs, it can drive the frame 509 to move downward through the connection with the mounting plate 508. After the frame 509 moves downward, it drives the rubber pad 510 to fit the film and the surface of the packaging bag. When the film is in the laminating position at the time, it is at the inner side of the frame 509, and the heat pump 518 and the third motor 523 are started at the same time. After the heat pump 518 is running, hot air is generated, and the hot air is transported to the position of the connecting pipe 513 through the connection of the air supply pipe 519. Then the hot air is sprayed downward from the position of the air outlet hood 515 through the connection of the air outlet pipe 514. At this time, the hot air will be sprayed downward to the surface of the film, so that the adhesive at the bottom of the film can fully act on the surface of the packaging bag, thereby completing the laminating process of the film and the packaging bag. At the same time, the operation of the third motor 523 will drive the first rotating shaft 524 to operate, and the second pulley 525 can be driven to rotate with the connection of the first rotating shaft 524. The second pulley 525 can rotate through the belt 521 and the first pulley 5 The connection of 20 drives the screw rod 511 to rotate accordingly. When the screw rod 511 rotates, it can drive the sliding seat 512 to move along the limit rod 528. At this time, the sliding seat 512 drives the air outlet hood 515 to move accordingly. The air outlet hood 515 can cover the fitting position of the film and move to complete the covering heating laminating. When the air outlet hood 515 moves, the second roller 517 will be in a state of fitting the surface of the film. At this time, with the continuous movement of the air outlet hood 515, hot air is sprayed onto the surface of the film. The rotation of the second roller 517 rolls the film, so that the film and the packaging bag are more closely fitted. The adhesive can be evenly covered on the surface of the packaging bag to complete the fitting, which effectively improves the quality of the laminating process. After the laminating process of bagging, the first electric push rod 402 and the second electric push rod 501 are started to move upward and reset, and then the first motor 2 is started to drive the conveyor belt 9 to run and send out the packaging bag. After the packaging bag that has completed the laminating process is sent out, the packaging bag is put in again and the first motor 2 is started for conveying and loading, and then the second motor 3 is started to run. After the second motor 3 runs, it can drive the second rotating shaft 13 to follow the rotation. The rotation of the second rotating shaft 13 can drive the winding roller 14 to follow the rotation. The winding roller 14 winds up the film while rotating, so that the new film is in the upper position of the packaging bag waiting for laminating, cutting and laminating processing, thereby achieving the purpose of automatically completing the laminating operation, saving manual operation steps, and effectively improving the processing efficiency.
