Description

Technical Field

[0001] The present application relates to the field of carton gluing technology, and in particular to a carton gluing mechanism. Background Art

[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. With its superior performance and good processing performance, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers and become the main force of transport packaging. In addition to protecting goods and facilitating storage and transportation, it also plays a role in beautifying and promoting goods. In the production process of corrugated cardboard, multiple layers of cardboard need to be glued together, which requires applying glue on the surface of the cardboard;

[0003] After searching, a carton gluing mechanism disclosed in Chinese patent CN219446297U is characterized in that a motor No. 1 is fixedly installed on one side of the movable block, the output end of the motor No. 1 is fixedly connected to the gluing roller, the fixed frame is rotatably installed with a threaded rod in the cavity, the threaded rod is threadedly connected to the movable block, a worm gear is fixedly installed on the bottom end of the threaded rod, a worm is rotatably installed on one side of the fixed frame, and the worm gear is meshed with the worm. The carton gluing mechanism has a simple structure, is easy to use, and has strong connectivity, so that the gluing roller can be easily adjusted in height according to the thickness of the corrugated paper, thereby improving the application range of the gluing device and enhancing its practicality.

[0004] However, the device uses a limiting plate to limit the cardboard, which can only prevent the cardboard from falling from both sides during transportation. However, due to the lack of anti-bias components, the position of the cardboard may shift during the activity, resulting in the final gluing position error, affecting the subsequent bonding effect of the carton. For this reason, we urgently need to provide a carton gluing mechanism.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application embodiment discloses a carton gluing mechanism, referring to Figure 1-Figure 4 , including a body 1, a conveyor belt 2 is installed on the inner side of the body 1, a conveying motor 3 is installed on the side of the body 1, the output end of the conveying motor 3 passes through the body 1 and is connected to the conveyor belt 2, and the conveyor motor 3 is used to drive the conveyor belt 2 to move, thereby completing the transportation of cardboard, two gantries 9 are evenly fixedly installed on the upper end of the body 1, and two movable rods 10 are movably connected to the upper ends of the two gantries 9. The upper ends of the two movable rods 10 are threadedly connected with nuts, which play a role in limiting the position of the movable rods 10, and the bottoms of the two movable rods 10 are fixedly installed with connecting seats 12, and the upper ends of the connecting seats 12 are evenly fixedly installed with two reset springs Spring 11, two return springs 11 are respectively sleeved on the outside of the two movable rods 10, and the cooperation of the return spring 11 and the movable rod 10 makes the connecting seat 12 and the pressing wheel 14 adapt to the thickness of the cardboard to press the cardboard. A fixing rod 13 is fixedly installed on the inner side of the connecting seat 12, and a plurality of pressing wheels 14 are evenly fixedly installed on the surface of the fixing rod 13. During the transportation of the cardboard, the pressing wheel 14 rolls on the surface of the cardboard to ensure that the position of the cardboard will not be offset, ensure the quality of the cardboard gluing, and avoid the position of the cardboard being offset during the activity, resulting in the wrong final gluing position.

[0024] Reference Figure 2A fixed frame 4 is fixedly installed in the middle of the upper end of the body 1, and a hydraulic cylinder 5 is installed on the upper end of the fixed frame 4. The bottom of the hydraulic cylinder 5 passes through the fixed frame 4 and is connected with a movable plate 6. The inner side of the movable plate 6 is rotatably connected with a glue coating roller 7. The hydraulic cylinder 5 drives the movable plate 6 to move up and down, which is convenient for adjusting the position of the glue coating roller 7. It is suitable for gluing cardboards of different thicknesses. The two ends of the movable plate 6 are slidably connected to the inner side of the fixed frame 4. A glue storage cylinder 8 is fixedly installed on the upper end of the fixed frame 4. The bottom of the glue storage cylinder 8 corresponds to the surface of the glue coating roller 7 by connecting a glue injection tube. The glue liquid inside the glue storage cylinder 8 is evenly applied to the surface of the glue coating roller 7 by the glue injection tube, and the glue coating roller 7 is rotated to apply glue to the surface of the cardboard.

[0025] Reference Figure 4 A mounting frame 15 is installed at one end of the inner side of the body 1, and a plurality of fixing bolts 16 are evenly arranged at the four corners of the mounting frame 15. The fixing bolts 16 penetrate the mounting frame 15 and are threadedly connected to the inner side of the body 1. By installing a detachable mounting frame 15 at the discharge end of the body 1, the mounting frame 15 can be disassembled when not in use, saving space. The mounting frame 15 is tilted as a whole, and a plurality of guide rollers 17 are evenly rotated and connected to the inner side of the mounting frame 15. When the glued cardboard slides to the inner side of the mounting frame 15 through the conveyor belt 2, the guide rollers 17 are used to transport the cardboard at a uniform speed. On the one hand, it prevents the cardboard from falling from a high place and flipping, causing the glued part to stick to the ground and affect the subsequent bonding effect. On the other hand, it slows down the discharge speed of the material, so that the staff can handle the cardboard unloaded from the previous batch in time, which is convenient for use.

[0026] The implementation principle of a carton gluing mechanism in an embodiment of the present application is as follows: when using the device, the cardboard is first transported through the conveyor belt 2. When passing the bottom of the gantry 9, the connecting seat 12 is adapted to the thickness of the cardboard through the action of the reset spring 11 and the movable rod 10, and its own position is adjusted. During the movement of the cardboard, the pressure wheel 14 at the bottom of the connecting seat 12 presses the upper end of the cardboard to limit and prevent deviation, thereby ensuring the stability of the cardboard during gluing. When the cardboard passes the bottom of the fixed frame 4, the hydraulic cylinder 5 is used to drive the movable plate 6 to adjust the position of the glue roller 7. The glue inside the glue storage cylinder 8 is smeared on the surface of the glue roller 7 through the glue injection tube. When the cardboard passes the bottom of the glue roller 7, the glue roller 7 is driven to rotate so that the surface of the cardboard is evenly glued.
