Problems solved by technology

However, when the cardboard is displaced by external environmental factors or human factors, the glue band on the cardboard will be displaced, and the glue band is a colorless and transparent strip-like structure, which is not easy to be directly observed by the human eye, resulting in The cardboard with offset glue tape flows into the subsequent packaging process, which affects the quality of the cardboard after folding and pasting. There is room for improvement in the existing technology

Embodiment 1

[0044] Such as figure 1 As shown, a gluing device includes a base 1 fixed on the frame of the automatic folder-gluer and a glue box 2 arranged on the base 1, the base 1 is set in a square shape, and the base 1 is set horizontally And lock with the frame of the automatic folder-gluer through bolts. The glue box 2 includes a box body 21 and a box cover 22. The box body 21 is locked on the base 1 through bolts, and the inside of the box body 21 is provided with a glue roller 3, and the top surface of the box body 21 is provided with a Squeeze the roller 4, and the cardboard is sandwiched between the gluing roller 3 and the squeeze roller 4 and passes through the gap between the two under the action of the transmission device of the automatic folder-gluer. The gluing roller 3 is connected with a motor 5 for driving its rotation. The motor 5 is fixed on the outside of the box body 21 and connected with the gluing roller 3 through a rotating shaft. The lower bottom surface of the ca...

Embodiment 2

[0055] combine Figure 4 with Figure 5 As shown, a gluing device differs from the first embodiment in that the supplementary method of the composite paint (fluorescent paint) is different: in this embodiment, the front and rear ends of the box body 21 are respectively provided with a set for storing pigments and fluorescent substances. The two storage bottles 9 are connected to the inside of the box body 21, and the storage bottles 9 are provided with a valve 91 for controlling the flow of the liquid. When it is necessary to add composite paint (fluorescent paint) to the inside of the box body 21, open the valves 91 of the two storage bottles 9 and stir evenly, or add another storage bottle 9 for storing glue on the side of the box body 21 , which is conducive to improving the convenience of feeding operations.

[0056] Below in conjunction with specific action this embodiment is further elaborated:

[0057] combine Image 6 As shown, the printing and gluing method: S1. D...

Abstract

The invention discloses a printing gluing method and a coating device, and relates to the field of package printing. The method comprises the following steps that S1, dust is removed, specifically, dust removal operation is conducted on a glue belt coating position on a paperboard before coating; S2, pigment is mixed, specifically, the pigment having the different bottom color with the paperboardis mixed into glue, and the glue and the pigment are stirred evenly to form composite coating; S3, gluing is conducted, specifically, the composite coating in the step S2 is evenly smeared on the coating position in the step S1 and forms a glue belt; and S4, detection is conducted, specifically, the position of the glue belt on the paperboard in the step S3 is detected. The pigment is mixed into the glue and stirred to form the composite coating, the composite coating is smeared to the corresponding position of the paperboard to form the glue belt, the color of the glue belt and the bottom color of the paperboard are obviously different, a user can detect the position of the glue belt later conveniently, and accordingly the folding and sticking of the paperboard or the subsequent folding and sticking quality of a packaging box are / is improved advantageously.

Description

technical field [0001] The invention relates to the field of packaging printing, in particular to a printing gluing method and a gluing device. Background technique [0002] Printing and packaging is to print decorative patterns or texts on various packaging materials to achieve the functions of conveying information and enhancing product attractiveness. In the assembly line operation of printing and packaging, multiple steps are involved, such as cardboard cutting, cardboard (paper) gluing, cardboard folding and bonding, and paper printing. The bonding and molding of packaging boxes play an important role. [0003] The existing authorized notification number is the Chinese patent of CN206335886U, which discloses an adjustable gluing mechanism of an automatic folder-gluer, including a plastic box base fixed on the frame of the automatic folder-gluer, and the plastic box base is connected to the machine. A slide bar and a screw rod assembly are connected between the frames,...
