Technical Field

[0001] The utility model relates to the technical field of environmentally friendly carton printing equipment, in particular to an environmentally friendly carton production printing device. Background Art

[0002] Environmentally friendly cartons are the most widely used packaging products, and their usage has always been the highest among all packaging products. For more than half a century, environmentally friendly cartons have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, becoming the main force of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods. Environmentally friendly cartons are made by die-cutting, creasing, nailing or gluing. Printing devices are often used in the production process to print trademark advertisements on the outer surface or inside of the environmentally friendly cartons.

DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 6 The utility model discloses an environmentally friendly carton production printing device, comprising a printing machine table 1, the upper end surface of the printing machine table 1 is provided with a printing groove 2, mounting frames 3 are arranged on both sides of the upper end of the printing machine table 1, and a printing mechanism 4 is commonly arranged at the upper ends of the two mounting frames 3;

[0028] A guide cavity 5 is provided inside the printing machine table 1, and an isolation plate 6 is provided inside the guide cavity 5. A plurality of vents 7 arranged in a rectangular array are provided on the inner upper cavity wall of the guide cavity 5 and on both sides of the isolation plate 6. A mounting plate 8 is provided at the bottom end of the isolation plate 6. The guide cavity 5 is divided into two cavities by the arrangement of the isolation plate 6 and the mounting plate 8. A plurality of guide fans 9 are provided inside the mounting plate 8. A guide mechanism 10 is provided on one side of the isolation plate 6. The hole opened in the middle of the mounting plate 8 for mounting the guide fan 9 is used to connect the two cavities.

[0029] In this embodiment, when in use, the printing groove 2 is set to position the paperboard. When the paperboard is placed inside the printing groove 2, the air in one cavity is introduced into the other cavity through the guide fan 9. At this time, the vents 7 corresponding to the two cavities will respectively inhale and exhaust air. The vents 7 for inhaling air will suck one side of the paperboard downward so that the bottom side of the paperboard fits with the bottom wall of the printing groove 2, and the vents 7 for exhausting air will push the other side of the paperboard upward, thereby causing the paperboard to tilt. After the paperboard tilts, the paperboard will move in the direction of the vents 7 for inhaling air until the side wall of the paperboard fits with the groove wall of the printing groove 2.

[0030] After the side wall of the paperboard contacts the groove wall of the printing groove 2, the number of ventilation holes for air intake under the paperboard is greater than the position of the ventilation holes for air exhaust, and with the gravity of the paperboard itself, the paperboard will gradually fall and stick to the lower wall of the printing groove 2, thereby achieving the purpose of positioning the paperboard;

[0031] In summary, positioning the cardboard by using its own gravity and the thrust of the air can effectively avoid bending or deformation of the cardboard, thereby achieving the purpose of improving the yield rate of printing and reducing the rate of scrapped products.

[0032] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the printing mechanism 4 includes two positioning rods 41, an adjusting screw 42 and a printing frame 43. Both ends of the positioning rods 41 and the adjusting screw 42 are rotatably connected to the mounting frame 3. Positions of the printing frame 43 corresponding to the positioning rods 41 and the adjusting screw 42 are respectively provided with positioning holes 44 and adjusting screw holes 45. The bottom end of the printing frame 43 is provided with a printing template.

[0033] In this embodiment, the positioning rod 41 and the positioning hole 44 are provided to guide the printing frame 43 so that the printing frame 43 can slide above the printing machine table 1 to adjust the printing position of the printing frame 43, and the adjustment screw hole 45 and the adjustment screw 42 are provided to adjust the position of the printing frame 43. Since the device positions the cardboard through the thrust of the air and the gravity of the cardboard, after the cardboard is positioned, the side wall of the cardboard fits with the side wall of the printing groove 2, and then the distance between the printing frame 43 and the side wall of the printing groove 2 is increased, so that the effect of printing at different positions of the cardboard is achieved.

[0034] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the guide fan 9 includes a rotating shaft 91 , annular brackets 92 are provided at both ends of the rotating shaft 91 , and both ends of the annular bracket 92 are respectively installed on both sides of the mounting plate 8 , and a driving fan 93 is provided in the middle of the outer surface of the rotating shaft 91 .

[0035] In this embodiment, the annular bracket 92 is provided to fix the rotating shaft 91 in the hole opened in the middle part of the mounting plate 8, and the rotating shaft 91 is provided to install the driving fan 93, and the driving fan 93 is provided with a driving motor inside to rotate the driving fan 93 on the outer wall of the rotating shaft 91, so as to generate flowing air inside the guide cavity 5 and achieve the effect of using the ventilation holes on both sides of the isolation plate 6 for air outlet and exhaust respectively.

[0036] In a further preferred embodiment of the present invention, Figure 1-6As shown, the guide mechanism 10 includes a wind guide rail 101 and a shielding plate 102. The wind guide rail 101 is installed inside the guide cavity 5, and the bottom end of the wind guide rail 101 is connected to the bottom end of one side of the mounting plate 8, and the shielding plate 102 is connected to the top end of one side of the mounting plate 8.

[0037] In this embodiment, the wind guide rail 101 is provided to guide the air exhausted by the guide fan 9, and the shielding plate 102 is provided to shield the vent 7 and the straight direction of the air flow to avoid negative pressure at the vent 7 due to the air flow. When the air flow is guided by the wind guide rail 101 to the upper end of the shielding plate 102, the air will be discharged through the vent 7 to generate an upward wind column, such as Figure 6 As shown, the black arrow is the trajectory of wind flow, thereby achieving the effect of lifting the side edge of the cardboard.

[0038] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a push plate 11 is provided on one side of the printing machine table 1 , the upper surface of the push plate 11 is flush with the bottom surface of the printing groove 2 , and a cardboard conveying belt 12 is sleeved on the outer surface of the push plate 11 .

[0039] In this embodiment, the pushing plate 11 is provided to guide the paperboard, and the paperboard conveying belt 12 is provided to guide the paperboard to the position of the printing groove 2 .

[0040] In a further preferred embodiment of the present invention, Figure 1-6 As shown, an elastic plate 13 is provided on the side wall of the printing groove 2 away from the guide mechanism 10 , and the elastic plate 13 is arched and has inclined plates at both ends.

[0041] In this embodiment, the elastic plate 13 can provide a buffer for the paperboard when the paperboard contacts the inner wall of the printing groove 2 to prevent the paperboard from colliding with the printing groove 2 and causing the paperboard to curl.
