Description

Technical Field

[0001] The utility model relates to the technical field of paper packaging box laminating, in particular to a laminating machine for printing food packaging boxes. Background Art

[0002] During the production and printing process of paper food packaging boxes, hot lamination is pasted on the cardboard, which can improve the strength of the cardboard and the wear resistance of the surface, and isolate the cardboard from the outside air to prevent deformation and cracking caused by corrosion, moisture and dryness due to corrosive gases in the atmosphere.

[0003] During the process of laminating the packaging box, as the packaging box paper is conveyed, the hot pressing roller squeezes the hot laminating film onto the paper, and the hot pressing film is adhered to the packaging box paper by heating. In order to squeeze the hot laminating film and the paper together, a rubber roller pressed with the hot pressing roller is provided. The thickness of the paper is diverse. When laminating paper of different thicknesses, it is necessary to adjust the height of the two ends of the rubber roller or the hot pressing roller. During this adjustment process, since the height of the two ends is adjusted successively, the axis of the rubber roller or the hot pressing film is prone to tilt, which affects the laminating effect of the paper.

[0004] To solve the above problems, we proposed a laminating machine for food packaging box printing. Utility Model Content

[0005] The utility model aims to solve the problems in the background technology and proposes a laminating machine for printing food packaging boxes.

[0006] The camming roller is an axle of the type that can move freely in the conveyor belt, and the camming roller is an axle of the type that can move freely in the conveyor belt.

[0007] In the above-mentioned laminating machine for printing food packaging boxes, the adjustment mechanism includes a support frame fixed at the front end of the second support plate, a bearing is fixedly embedded in the middle of the support frame, a threaded tube is fixedly inserted in the bearing, the interior of the threaded tube is matched with a vertically upward threaded rod, the upper end of the threaded rod is fixedly connected to a rotating end, and the outer side wall of the rotating end is rotatably connected to a slot slidably arranged on the side of the conveying plate.

[0008] In the above-mentioned laminating machine for printing food packaging boxes, the outer side walls of the support plate 1 and the support plate 2 are fixedly connected with a blanking plate located at the rear side of the conveying plate.

[0009] In the above-mentioned laminating machine for printing food packaging boxes, the outer side wall of the second support plate is fixedly connected with a motor, and the driving end of the motor is fixedly connected to the end of the second rotating shaft.

[0010] In the above-mentioned laminating machine for printing food packaging boxes, the outer side wall of the guide roller is smoothly arranged.

[0011] In the above-mentioned laminating machine for printing food packaging boxes, a handle is fixedly provided on the outer side wall of the threaded tube.

[0012] Compared with the existing technology, the advantages of this food packaging box printing laminating machine are:

[0013] The utility model adjusts the height of the threaded rod in the threaded tube, and the rotating block drives the card slot to move up and down. The card slot rotates and slides relative to the transmission plate, so that the transmission plate deflects, thereby changing the distance between the rubber roller and the hot pressing roller to adapt to paper sheets of different thicknesses. In addition, the heights of both ends of the rubber roller are adjusted simultaneously, which ensures that the axis of the rubber roller is parallel during the adjustment process and does not affect the laminating effect.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4 A laminating machine for printing food packaging boxes comprises a supporting plate 1 and a supporting plate 2, a cross bar 3 is fixedly connected between the supporting plate 1 and the supporting plate 2, a vertical groove 4 is provided at the upper end of the supporting plate 1 and the supporting plate 2, a rotating shaft 5 is movably inserted in the vertical groove 4, an opening is provided at the upper end of the vertical groove 4, and a film-wrapping roller 6 is movably sleeved on the outer wall of the rotating shaft 5, a guide roller 7 located in front of the film-wrapping roller 6 is provided between the supporting plate 1 and the supporting plate 2, and the outer wall of the guide roller 7 is smoothly arranged, a rotating shaft 2 8 located at the lower side of the film-wrapping roller 6 is movably inserted between the supporting plate 1 and the supporting plate 2, a hot pressing roller 9 is fixedly sleeved on the outer wall of the rotating shaft 2 8, a motor 18 is fixedly connected to the outer wall of the supporting plate 2, and a driving end of the motor 18 The support base 10 is symmetrically arranged on the upper side walls of the support plates 1 and 2 and is located at the rear side of the cross bar 3. The support base 10 is rotatably connected to the conveying plate 11 located at the lower side of the hot pressing roller 9. The middle part of the conveying plate 11 is provided with a rubber roller corresponding to the hot pressing roller 9. The outer side walls of the support plates 1 and 2 are fixedly connected to a blanking plate 17 located at the rear side of the conveying plate 11. The hot coated film on the wrapping roller 6 bypasses the guide roller 7, and its end is squeezed onto the hot pressing roller 9 by the rubber roller on the conveying plate 11. When the glued paper sheet on the conveying plate 11 is inserted between the hot pressing roller 9 and the rubber roller, the motor 18 works and the hot pressing roller 9 rotates. The hot pressing roller 9 squeezes the conveyed paper sheet and the hot coated film at the same time, so that the hot coated film and the paper sheet are pressed into shape and fall onto the blanking plate 17.

[0021] An adjustment mechanism is provided between the support plate 2 and the conveying plate 11, and the adjustment mechanism includes a support frame 12 fixed at the front end of the support plate 2, a bearing is fixedly embedded in the middle of the support frame 12, a threaded tube 13 is fixedly inserted in the bearing, a vertically upward threaded rod 14 is matched inside the threaded tube 13, a rotating end 15 is fixedly connected to the upper end of the threaded rod 14, and a slot 16 slidably arranged on the side of the conveying plate 11 is rotatably connected to the outer wall of the rotating end 15, and a handle is fixedly provided on the outer wall of the threaded tube 13. When laminating paper sheets of different thicknesses, it is necessary to adjust the distance between the rubber roller and the hot pressing roller 9 to prevent the rubber roller and the hot pressing roller 9 from being pressed too loosely and affecting the laminating effect.

[0022] The distance between the rubber roller and the hot pressing roller 9 can be changed by adjusting the conveying plate 11, and the handle is turned to rotate the threaded tube 13, and the threaded rod 14 engages with the threaded tube 13 to move. The threaded rod 14 will drive the rotating end 15 to move up and down, and the slot 16 will move accordingly. During the up and down movement of the slot 16, it rotates and slides relative to the side wall of the conveying plate 11, causing the conveying plate 11 to deflect, thereby adjusting the distance between the rubber roller and the hot pressing roller 9. Since the rubber roller deflects as a whole with the conveying plate 11, the axis of the rubber roller always remains parallel to the axis of the hot pressing roller 9, which will not affect the lamination effect.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
