[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least a layer of wavy core paper interlayer and a layer of cardboard. It has good elasticity and extensibility and is mainly used to make cartons, cardboard sandwiches and other packaging materials for fragile goods. It mainly uses traditional straw pulp and waste paper through pulping to make raw cardboard similar to yellow cardboard, which is then mechanically processed and rolled into a corrugated shape. Then, sodium silicate and other adhesives are used on its surface to bond it with boxboard. Therefore, a bonding device is needed to bond the cardboard and the core paper interlayer.

[0004] During use, the pasting device in this announcement number requires that the cardboard and paper core to be pasted be placed on two placing and closing plates. Although the placing and closing plates can be rotated to achieve the effect of automatic unloading, the cardboard still needs to be placed manually on the closing plates during the loading process. Therefore, a pasting device for corrugated cardboard processing is proposed. Utility Model Content

[0023] It is worth mentioning that a control panel is provided on the side wall of the processing table 1, and the first electric push rod 15, the second electric push rod 121, the third electric push rod 129, the cylinder 8, the servo motor 43, the pump body 7 and the linear electric guide rail 10 are all electrically connected to the control panel.

[0024] A linear electric guide rail 10 is provided on the side wall of the support plate 5, and the linear electric guide rail 10 is slidably connected to a slide 11, and a loading mechanism 12 is provided on the slide 11. A discharge port 3 is opened at the center of the processing table 1, and a lifting component 4 is provided at the bottom of the processing table 1, and a rotating part is provided on the lifting component 4.

[0025] The feeding mechanism 12 includes a second electric push rod 121, which is arranged on the slide 11. A mounting plate 122 is fixedly connected to the telescopic end of the second electric push rod 121. An air pump 123 is provided on the top of the mounting plate 122. A confluence cavity 126 is opened inside the mounting plate 122. A plurality of air pipes 124 are provided at the bottom of the mounting plate 122, all of which are connected to the confluence cavity 126. A suction cup 125 is provided at the bottom of the air pipe 124. A third electric push rod 129 is provided on both sides of the top of the mounting plate 122. A pressure plate 127 is fixedly connected to the telescopic end of the third electric push rod 129. An exhaust pipe is connected to the air pump 123.

[0026] A plurality of circular holes 128 are defined inside the pressing plate 127 , and the suction cups 125 are located inside the circular holes 128 .

[0027] It should be noted that the second electric push rod 121 pushes the mounting plate 122 downward, so that the suction cup 125 fits the surface of the paper core board. The air pump 123 draws air to form a negative pressure, which can suck the paper core board, and then drive the paper core board to be automatically loaded. After the cardboard and the paper core board are bonded together, the pressing plate 127 can be used to further lightly press the cardboard together to ensure the firmness of the bonding.

[0028] See also Figure 3 In this embodiment, the lifting assembly 4 includes a fixed plate 41, which is fixedly connected to the bottom of the processing table 1.

A sliding hole 47 is opened inside the fixed plate 41, and one end of the moving rod 44 extends through the sliding hole 47 to the outside and is fixedly connected to the lifting plate 46.

[0029] It should be noted that, by driving the lifting plate 46 to move up and down through the lifting assembly 4, the placement plate 14 can be moved out of the discharge port 3 or returned to its original position, thereby facilitating discharge.

[0030] See also Figure 1 、 Figure 2 The rotating part includes a placement plate 14, the bottom of the placement plate 14 is hinged with a vertical rod 13, the vertical rod 13 is arranged on the top of the lifting plate 46, the side wall of the vertical rod 13 is hinged with a first electric push rod 15, the telescopic end of the first electric push rod 15 is hinged at the bottom of the placement plate 14, and the placement plate 14 matches the inner wall of the discharge port 3.

[0031] It is understandable that when the placement plate 13 moves downward, the placement plate 14 can be tilted by controlling the first electric push rod 15 to push the placement plate 14 to rotate to one side, so that the bonded cardboard can slide down and be automatically unloaded.

[0032] The working principle of the above embodiment is as follows: when in use, the cardboard and paper core are intermittently conveyed by the conveyor belts 2 on both sides, so that the cardboard on one side is first conveyed to the top of the placement plate 14, and then the adhesive in the glue storage box 6 is extracted by the pump body 7 and sprayed on the surface of the cardboard through the glue spraying part 9, and then the second electric push rod 121 pushes the mounting plate 122 downward to make the suction cup 125 fit the surface of the paper core board, and the air pump 123 is used to pump air to form a negative pressure to suck the paper core board, and the linear electric guide rail 10 drives the paper core board to move above the cardboard and places the paper core board on the top of the cardboard through the third electric push rod 129, and then the third electric push rod 129 pushes the pressing plate 127 downward to press the cardboard and the paper core board, and then the lifting assembly 4 drives the placement plate 14 to move down and move out of the discharge port 3, and then the first electric push rod 15 pushes the placement plate 14 to rotate to one side to make the bonded cardboard slide down, thereby realizing automatic loading and unloading.
