Description

Technical Field

[0001] The utility model relates to the technical field of laminating devices, in particular to a laminating device for label printing. Background Art

[0002] Laminating is to put a layer of transparent plastic film on paper products. Specifically, if the easily worn parts such as the cover of the product manual printing and the outer surface of the paper box need a protective film, it should be laminated after printing and before folding and cutting. This film must be very transparent, have good toughness, uniform texture, no sand holes or bubbles, and a very flat surface. The printing factory uses a hot pressing roller to firmly stick it on the paper.

[0003] For example, publication number CN213798747U discloses a laminating device for a label printing machine, which drives the exhaust plate to move downward through an electric telescopic rod, so that the exhaust plate presses down on the printed product after lamination, thereby making the film and the printed product fit more closely, and can remove bubbles between the film and the printed product, so that the laminating effect of the laminating structure is better.

[0004] However, when the exhaust structure is in use, the printing machine is used for a long time and the labels to be laminated are moving continuously. This requires the electric telescopic rod to move back and forth quickly to remove bubbles during the exhaust work, while the speed of the conventional electric telescopic rod is not so fast. As a result, bubbles cannot be removed from a part of the surface of the laminated label, thereby reducing the use effect of the device. In view of this, we propose a laminating device for label printing. Utility Model Content

A driving wheel 36 is fixedly installed on the side wall of the plate 32, a driven wheel 37 is fixedly installed on the surface of the rotating rod 33, a fixed frame 38 is fixedly installed on the side wall of the support plate 32, a moving rod 39 passes through the fixed frame 38, a defoaming plate 310 is fixedly installed on the lower end of the moving rod 39, a partition plate 311 is fixedly installed on the inner wall of the fixed frame 38, a return spring 312 is provided on the surface of the moving rod 39, a rack 313 is fixedly installed on the surface of the moving rod 39, a rotating rod 314 is rotatably connected to the inner wall of the fixed frame 38, a half gear 315 is fixedly installed on the surface of the rotating rod 314, and an adjusting structure 4 for adjusting the height of the coating roller 5 is provided inside the U-shaped frame 31.

[0023] Specifically, the protective structure 3 of the technical solution of the utility model includes: a U-shaped frame 31, a support plate 32, a rotating rod 33, a slide 34, a motor 35, a driving wheel 36, a driven wheel 37, a fixed frame 38, a moving rod 39, a defoaming plate 310, a partition 311, a return spring 312, a rack 313, a rotating rod 314, and a half gear 315.

[0024] In one embodiment of the utility model, a protective structure 3 is provided to facilitate the elimination of bubbles at the coating of the label surface by long-term movement of the moving rod 39 and the defoaming plate 310. When in use, the user can start the electric conveyor 2 to work, and the labels placed on its surface are slowly transported by the electric conveyor 2, and then these labels are moved to the bottom of the coating roller 5 for coating. At this time, the user can start the motor 35 to work, and the output shaft of the motor 35 drives the driving wheel 36 on its surface to rotate, and the driving wheel 36 drives the driven wheel 37 meshing with it to rotate, so that the label surface is coated by the rotation of the coating roller 5. At the same time, since the driving wheel 36 is a small gear and the driven wheel 37 is a large gear, the driven wheel 37 drives the coating roller 5 to rotate at a slower speed, and the rotation speed of the coating roller 5 is controlled by the rotation speed of the motor 35.

[0025] At the same time, the output shaft of the motor 35 drives the first pulley on its surface to rotate, and the rotation of the first pulley drives the synchronous belt 7 to rotate and the second pulley to rotate, and the rotation of the second pulley drives the rotating rod 314 to rotate, and the rotation of the rotating rod 314 drives the half gear 315 on its surface to rotate. At this time, the engagement between the half gear 315 and the rack 313 causes the rack 313 to drive the moving rod 39 to move downward, and the half gear 315 continues to rotate. At this time, the half gear 315 is no longer engaged with the rack 313. At this time, the elastic force of the reset spring 312 drives the moving rod 39 to move upward for reset, and finally, the half gear 315 is continuously rotated to make the moving rod 39 move up and down, and then the movement of the moving rod 39 drives the defoaming plate 310 at its lower end to move back and forth quickly up and down to defoam the label coating, thereby improving the use effect of the device without the need for an additional driving device.

[0026] By setting up the adjustment structure 4, it is convenient to adjust the overall position of the laminating roller 5 and the defoaming plate 310. When in use, the user can drive the screw 42 to rotate by turning the handle 6. At this time, the screw 42 rotates inside the sleeve 41, so that the screw 42 moves up and down and drives the U-shaped plate 43 at its lower end to move. The movement of the U-shaped plate 43 drives the two groups of support plates 32 at its lower end to move, so that the laminating roller 5 and the defoaming plate 310 can better perform lamination and defoaming on label papers of different thicknesses.

[0027] Please continue reading Figure 1-Figure 4 The adjusting structure 4 includes a sleeve 41 fixedly mounted on the upper end of the U-shaped frame 31, a screw 42 is threadedly connected to the inner surface of the sleeve 41, and the lower end of the screw 42 is rotatably connected to a U-shaped plate 43 through a sleeve. The lower ends of the U-shaped plate 43 are respectively fixedly connected to the upper ends of the two groups of support plates 32 on both sides, and a handle 6 is fixedly mounted on the upper end of the screw 42. A first pulley is fixedly mounted on the surface of the motor 35, and a second pulley is fixedly mounted on the surface of the rotating rod 314. A synchronous belt 7 is connected between the first pulley and the second pulley. One end of the return spring 312 is fixedly connected to the side wall of the partition 311, and the other end of the return spring 312 is fixedly connected to the inner wall of the fixed frame 38. Two groups of supporting legs are arranged at the lower end of the bracket 1, and the moving trajectory of the support plate 32 is adapted to the size of the sliding opening 34.

[0028] During operation, the user can first adjust the position of the laminating roller 5, and then turn the handle 6 to drive the screw 42 to rotate. At this time, the screw 42 rotates inside the sleeve 41, so that the screw 42 moves and drives the U-shaped plate 43 to move, and the support plate 32 is driven to move by the movement of the U-shaped plate 43, and then the label is placed on the surface of the electric conveyor belt 2 to move, and then the motor 35 is started to drive the driving wheel 36 on its surface to rotate, and the driving wheel 36 rotates to drive the driven wheel 37 engaged with it to rotate, so that the label surface is coated by the rotation of the laminating roller 5, and at the same time, the output shaft of the motor 35 rotates to drive the first pulley on its surface to rotate, and the first belt conveyor belt 2 is driven to rotate. The rotation of the wheel drives the synchronous belt 7 and the second pulley to rotate, and the rotation of the second pulley drives the rotating rod 314 to rotate, and the rotation of the rotating rod 314 drives the half gear 315 on its surface to rotate. At this time, the meshing between the half gear 315 and the rack 313 causes the rack 313 to drive the moving rod 39 to move downward, and the half gear 315 continues to rotate. At this time, the half gear 315 is no longer meshed with the rack 313. At this time, the elastic force of the reset spring 312 drives the moving rod 39 to move upward for reset. Finally, the continuous rotation of the half gear 315 causes the moving rod 39 to move up and down to defoam the label coating, thereby improving the use effect of the device.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
