Description

Technical Field

[0001] The utility model relates to the technical field of food packaging films, in particular to a conveying mechanism for printing food packaging films with a leveling function. Background Art

[0002] Food packaging film is a polymer material used to wrap the surface of food, mainly to isolate and decompose the entry of microorganisms, bacteria and foreign pollutants, and prevent and prolong the deterioration of food. During the packaging process of food packaging film, it is often necessary to print the surface of the packaging film to play an advertising role by printing various patterns. The surface printing of food packaging film is often carried out by a packaging film printing machine, and the packaging film often needs to be conveyed during the printing process of the packaging film printing machine.

[0003] The existing food packaging film printing and conveying device will print when the packaging film surface is uneven, which will result in poor printing quality. The uneven surface will cause uneven adhesion of ink, resulting in reduced clarity of printed patterns and texts, uneven colors, and varying depths, which seriously affects the appearance of the packaging and is also prone to damage to the printing equipment. Utility Model Content

[0004] The utility model discloses a conveying mechanism for printing food packaging film with a leveling function, aiming to solve the technical problems that the existing food packaging film printing conveying device will cause poor printing quality, uneven ink adhesion, reduced clarity of patterns and texts, uneven colors, damage to packaging appearance, and easy damage to printing equipment when the packaging film is not level.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a conveying mechanism for printing food packaging film with a leveling function, comprising a workbench, a leveling component is arranged above the workbench, the leveling component comprises a driving motor 1, a power output shaft of the driving motor 1 is connected to a slide plate through a bearing transmission, a driving gear is fixedly connected to the top of the slide plate, and a linkage gear is movably connected to the outer side of the driving gear, the linkage gear and the driving gear are meshed with each other through a tooth groove 1, the bottom end of the linkage gear is movably connected to the bottom end of the slide plate, a connecting rod is fixedly connected to the top of the linkage gear, a swing rod is movably connected to the top of the connecting rod, a connecting rod is fixedly connected to the bottom end of the swing rod, and a leveling roller is rotatably connected to the outer side of the connecting rod, a limiting shaft is fixedly connected to the front end of the limiting shaft, a telescopic rod is fixedly connected to the end of the telescopic rod away from the leveling roller, a connecting frame is fixedly connected to the bottom end of the connecting frame and the front end of the workbench, a compression spring 1 is fixedly connected to the limiting shaft and the opposite side of the connecting frame at an equal distance, and the compression spring 1 surrounds the outside of the telescopic rod.

[0006] By setting up a workbench and a leveling component, before printing on the food packaging film, the driving motor is started to drive the active gear to rotate, and the linkage gear meshing with the active gear through the tooth groove rotates above the slide plate, and the connecting rod and the swing rod at the top of the linkage gear swing back and forth above the packaging film, and then the packaging film is leveled by the leveling roller, and the telescopic rod acts as a limiter on the swing rod. During the process, the leveling component can provide a more uniform surface for printing after the packaging film is leveled. The flat surface allows the ink to adhere evenly, making the printed pattern and text clearer and the color more accurate. In addition, the flat surface can better contact with the printing equipment, which helps to improve the accuracy of printing and ensure the registration accuracy of printing, thereby improving the overall printing quality.

[0007] The top of the workbench is fixedly connected to the base, the bottom end of the driving motor is fixedly connected to the bottom frame, and the bottom frame is fixedly connected to the front end of the workbench, and the bottom frame and the connecting frame are both located on one side of the base, and the top of the workbench is fixedly connected to a symmetrical support plate, and the symmetrical support plates are both located on both sides of the base, and the opposite side of the support plate is movably connected to a packaging film roller, and the opposite side of the support plate is fixedly connected to an auxiliary pressing roller, the auxiliary pressing roller is located in front of the packaging film roller, and the outer side of the packaging film roller is movably connected to a food packaging film body, the food packaging film body is located below the auxiliary pressing roller, the front end of the food packaging film body contacts the outer side of the leveling roller, and the top of the workbench is fixedly connected to a symmetrical support frame, and the support frame is located in front of the leveling assembly.

[0008] A base, a bottom frame, a support plate, a packaging film roller, an auxiliary pressing roller, a food packaging film body and a support frame are provided. Before the food packaging film is printed, the bottom frame fixes the position of the leveling component and simultaneously places the food packaging film body on the outside of the packaging film roller, draws out one end and places it under the auxiliary pressing roller, and then the packaging film is leveled by the leveling component.

[0009] The transmission gear of the present invention is a gear which is connected with the gear of the gear to the upper and lower ends of the gear train, and the gear is engaged with the gear of the gear train through two tooth grooves, and the gear is engaged with the gear of the gear train.

[0010] By providing a printing component, when printing on the food packaging film, the second driving motor is started to drive the rotating gear to rotate on the gear plate, and the telescopic bottom plate fixedly connected to the gear plate moves downward, so that the printed part contacts the surface of the packaging film, and printing on the surface of the packaging film is achieved. At the same time, the second spring is compressed to reset the telescopic bottom plate. During the process, the distance between the printed part and the packaging film can be adjusted according to the thickness of the packaging film through the printing component, ensuring that the printing pressure is appropriate so that the ink is evenly transferred to the surface of the packaging film, thereby improving the printing quality and ensuring that the pattern is complete and the color is rich.

[0011] From the above, it can be seen that the utility model provides a conveying mechanism for printing food packaging film with a leveling function, which has a leveling component. The leveled packaging film can provide a more uniform surface for printing. The flat surface allows the ink to adhere evenly, making the printed patterns and text clearer and the colors more accurate. In addition, the flat surface can better contact with the printing equipment, which helps to improve the accuracy of printing and ensure the registration accuracy of printing, thereby improving the technical effect of the overall printing quality.
