[0017] Reference Figures 1-4 A double-sided gluing device for processing corrugated cardboard includes a workbench 8. A first chute 10 is provided on the top of the workbench 8. A connecting frame 2 is fixed to the upper surface of the workbench 8 by bolts. A through hole is provided on the connecting frame 2. A glue pipe 6 is fixedly inserted into the through hole. Multiple glue spray holes 9 are provided on the two vertical pipes at the bottom of the glue pipe 6. A glue supply assembly is provided on the connecting frame 2 and communicates with the glue pipe 6. The glue supply assembly includes a glue tank 1. The glue tank 1 is fixed to the upper surface of the connecting frame 2 by bolts. A glue pump 5 is fixed to the upper surface of the connecting frame 2 by bolts. The glue pump 5 is of model NYP3 / 1.0-NYP30. The liquid extraction end of the glue pump 5 is connected and fixed to the glue tank 1. The liquid outlet end of the glue pump 5 is connected and fixed to the glue pipe 6. When the glue pump 5 is started, the glue in the glue tank 1 enters the glue pipe 6 and is sprayed out through the glue spray holes 9.

[0018] Specifically, the worktable 8 is provided with a first slide groove 10. A sliding bracket 12 is bolted to the inner top wall of the worktable 8. Two I-shaped slide rails 15 are bolted to the bottom of the sliding bracket 12. Two sliders 13 are slidably connected to the two I-shaped slide rails 15, which guide the sliders 13. A power assembly is provided on the inner top wall of the worktable 8 to drive the two sliders 13 to move towards or away from each other. The power assembly includes a mounting bracket 19, which is bolted to the inner top wall of the worktable 8. The mounting bracket 19 contains... An electric push rod 18 is bolted to the device. The electric push rod 18 is a self-locking type, model DT1000-500. One end of the electric push rod 18 is bolted to a connecting buckle 17. Two connecting rods 16 are rotatably connected to the connecting buckle 17, and the two connecting rods 16 are rotatably connected to the sliders 13 respectively. The distance between the two glue-applying rollers 7 is adjusted according to the thickness of the corrugated paper. The electric push rod 18 extends and retracts, causing the connecting buckle 17 to pull the connecting rods 16 to move, thereby causing the two sliders 13 to move towards or away from each other along the I-shaped slide rail 15, thus adjusting the distance between the glue-applying rollers 7 on the two connecting shafts.

[0019] It should be noted that the sliding bracket 12 is provided with a second sliding groove 14, and the upper surfaces of the two sliders 13 are rotatably connected to a rotating shaft. One end of the rotating shaft passes through the second sliding groove 14 and the first sliding groove 10 and is detachably connected to the glue application roller 7 by bolts. Glue is applied to the glue application roller 7 through the glue spray hole 9. The bottom of the two sliders 13 is provided with a driving component that drives the rotating shaft to rotate. The driving component includes a motor, which is fixed to the bottom of the slider 13 by bolts. One end of the motor output shaft passes through the slider 13 and is fixed to the rotating shaft. The two motors rotate in opposite directions. The placement frame 3 is located in the middle of the two glue application rollers 7, and the glue spray hole 9 is located on the side of the glue application roller 7. Since the two motors rotate in opposite directions, the rotation of the two motors causes the rotating shaft to drive the glue application roller 7 to rotate in the opposite direction.

[0020] In particular, the top of the workbench 8 is provided with a guide groove 11, and a guide block is slidably connected in the guide groove 11. The top of the guide block is fixed with a placement frame 3 by bolts. The corrugated paper that needs to be coated with glue is placed vertically on the placement frame 3, so that the horizontal bar of the placement frame 3 provides auxiliary support to the bottom of the corrugated paper, and the side of the corrugated paper is in contact with the vertical bar of the placement frame 3. The worker holds the corrugated paper and pushes the placement frame 3, so that the guide block moves along the guide groove 11. At this time, the corrugated paper placed on the placement frame 3 moves and enters the gap between the two glue rollers 7, and comes into contact with the two glue rollers 7. During the movement of the corrugated paper, the glue rollers 7 apply glue to both sides of it.

[0021] Working principle: When it is necessary to apply glue to both sides of the honeycomb corrugated cardboard, first place the corrugated cardboard to be glued vertically on the placement frame 3, so that the horizontal bar of the placement frame 3 provides auxiliary support to the bottom of the corrugated cardboard, and the side of the corrugated cardboard contacts the vertical bar of the placement frame 3. Adjust the distance between the two glue-coating rollers 7 according to the thickness of the corrugated paper. That is, start the electric push rod 18, the electric push rod 18 retracts, causing the connecting buckle 17 to pull the connecting rod 16 to move, thereby causing the two sliders 13 to move towards the middle along the I-shaped slide rail 15, thereby adjusting the distance between the glue-coating rollers 7 on the two connecting shafts. The staff started two motors. Since the two motors rotated in opposite directions, the rotation of the two motors caused the shaft to drive the glue roller 7 to rotate in the opposite direction, and started the glue pump 5, so that the glue in the glue tank 1 entered the glue pipe 6 and went to the glue roller 7 through the glue spray hole 9. The staff holds the corrugated paper and pushes the placement frame 3, causing the guide block to move along the guide groove 11. At this time, the corrugated paper placed on the placement frame 3 moves and enters the gap between the two glue rollers 7, and comes into contact with the two glue rollers 7. During the movement of the corrugated paper, the glue rollers 7 apply glue to both sides of it.

[0022] In this application, two motors are electrically connected to an external encoder. The encoder converts the motor speed signal into an electrical signal in real time and feeds it back to the external controller. Using the signal fed back by the encoder, a closed-loop control system is constructed. The external controller automatically adjusts the motor input based on the deviation between the fed-back speed signal and the set speed to eliminate the deviation and ensure that the two motors always rotate at the same speed. This application uses a programmable logic controller (PLC) as the main control unit. It receives sensor signals through digital input and output modules and controls the motor start-stop and electric actuator movement. This method is common knowledge to those skilled in the art. This utility model is a direct application of the prior art and is not within the protection scope of this utility model. Therefore, it will not be described in detail.
