Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, in particular to a heating and speed-up device for corrugated paperboards. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] At present, in the heating process of most corrugated cardboards, the corrugated board body is first heated, then transported to the gluing area, and then heated for the second time. This consumes a lot of labor and reduces the processing efficiency of the corrugated cardboard.

[0004] Therefore, we propose a corrugated cardboard heating and speed-up equipment. Utility Model Content

The staff puts the corrugated cardboard into the clamp assembly, and the heating box 4 is fixedly installed above the clamp assembly, and the end of the heating box 4 close to the clamp assembly is a grid plate, so that when the staff turns on the heating device set in the heating box 4, the hot air will fall into the corrugated cardboard clamped by the clamp assembly through the grid plate. When the corrugated cardboard close to the heating box 4 is heated, the staff starts the rotating device set in the clamp assembly, so that the corrugated cardboard enters The corrugated cardboard rotates and continues to heat. When the corrugated cardboard is heated, the rotating device is set to make the corrugated cardboard fall on the conveyor belt 1 to continue the next processing. There is a gluing area between the heating box 4 and the connecting plate 15. When the corrugated cardboard moves here, the staff glues and bonds the corrugated cardboard. The pasted corrugated cardboard will move to the connecting plate 15 with the movement of the conveyor belt 1. A heating roller 20 is rotatably installed between the two connecting plates 15, so that the bonded corrugated cardboard will be heated again when passing through the heating roller 20, so that the colloid bonded inside the corrugated cardboard is heated, so that each layer of the corrugated cardboard is more closely fitted. At the same time, the assembly line operation greatly improves the working efficiency of the corrugated cardboard processing.

[0028] like Figure 1-Figure 4 As shown, the clamp assembly includes: a bracket 7, a rotating rod 1301, a vertical plate 8, an upper horizontal plate 9 and a lower horizontal plate 10. The lower surface of the bracket 7 is fixedly connected to the upper end of the baffle 2. A No. 1 driving device 13 is fixedly installed inside the bracket 7. The bracket 7 is fixedly connected to the baffle 2 by setting it. At the same time, the bracket 7 is connected to the vertical plate 8 through the rotating rod 1301, and the upper and lower ends of the vertical plate 8 are connected to the upper horizontal plate 9 and the lower horizontal plate 10, so that the corrugated cardboard is located between the upper horizontal plate 9 and the lower horizontal plate 10, so that the corrugated cardboard can be located above the conveyor belt 1 for heating.

[0029] Example 2

[0030] A corrugated cardboard heating and speed-up device, such as Figure 1-Figure 5As shown, the output end of the No. 1 driving device 13 is fixedly connected with a rotating rod 1301, and the end of the rotating rod 1301 away from the No. 1 driving device 13 is fixedly connected to the vertical plate 8, and a No. 1 spring 11 is fixedly installed inside the vertical plate 8, and the No. 1 spring 11 is fixedly connected to the upper horizontal plate 9. A No. 1 rotating shaft 12 is fixedly connected to the surface of one side of the lower horizontal plate 10, and one end of the No. 1 rotating shaft 12 is fixedly connected to the vertical plate 8. The staff places the corrugated cardboard between the upper horizontal plate 9 and the lower horizontal plate 10, and the No. 1 spring 11 is fixedly connected to the upper horizontal plate 9, so that the distance between the upper horizontal plate 9 and the lower horizontal plate 10 can be changed according to the thickness of the corrugated cardboard. When the corrugated cardboard is too thick, the No. 1 spring 11 is stretched, and the upper horizontal plate 9 moves vertically at the same time, and when the No. 1 spring 11 is not stretched, the upper horizontal plate 9 and the lower horizontal plate The distance directly pressed by the plate 10 is the minimum thickness of the corrugated cardboard. When the staff needs to flip the corrugated cardboard, start the No. 1 driving device 13 to make it work. By setting the output end of the No. 1 driving device 13 to be fixedly connected with the rotating rod 1301, the rotating rod 1301 is rotated. At the same time, the rotating rod 1301 is fixedly connected with the vertical plate 8, and the vertical plate 8 is connected with the upper horizontal plate 9 and the lower horizontal plate 10, so that the upper horizontal plate 9, the lower horizontal plate 10 and the vertical plate 8 are rotated, so that the corrugated cardboard clamped by them is rotated and flipped. When the corrugated cardboard is heated, the staff turns on the No. 2 driving device 14, so that the No. 1 rotating shaft 12 fixedly connected to its output end is rotated. By setting the No. 1 rotating shaft 12 to be fixedly connected with the lower horizontal plate 10 and rotatably connected with the vertical plate 8, the lower horizontal plate 10 is rotated, so that the corrugated cardboard falls onto the conveyor belt 1.

[0031] like Figure 1-Figure 3As shown, at least two fans 5 are fixedly installed on the inner wall of the heating box 4, at least two heating wires 6 are fixedly installed under the fans 5, at least two grooves 16 are opened on the surface of one side of the connecting plate 15, and No. 2 springs 17 are fixedly installed on the upper and lower ends of the grooves 16, and a sleeve 18 is fixedly installed between the two No. 2 springs 17, and a No. 2 rotating shaft 19 is rotatably installed on the sleeve 18, and the No. 2 rotating shaft 19 is fixedly connected to the heating roller 20. The staff first turns on the heating wire 6 to heat the air in the heating box 4, and then turns on the switch of the fan 5 to blow the hot air in the heating box 4 through the mesh plate at the lower end of the heating box 4 to the corrugated cardboard clamped by the clamp assembly, so that The corrugated cardboard can be heated by hot air. When the corrugated cardboard is heated, it moves to the heating roller 20 through the conveyor belt 1. By setting a No. 2 spring 17, and the No. 2 spring 17 is fixedly connected to the sleeve 18, and the sleeve 18 is rotatably connected to the heating roller 20, the distance between the heating roller 20 and the conveyor belt 1 can be changed, so that the heating roller 20 can reheat the corrugated cardboard of different thicknesses. By setting a No. 2 rotating shaft 19 fixedly connected to the heating roller 20, when the corrugated cardboard moves, the heating roller 20 rotates, so that the heating roller 20 can reheat the entire corrugated cardboard, making it more firmly bonded.

[0032] Working principle: A heating box 4 is fixedly installed above the clamp assembly, and one end of the heating box 4 close to the clamp assembly is a mesh plate, so that when the staff turns on the heating device set in the heating box 4, the hot air will fall through the mesh plate onto the corrugated cardboard clamped by the clamp assembly. When the corrugated cardboard near the heating box 4 is heated, the staff starts the rotating device set in the clamp assembly, so that the corrugated cardboard rotates and continues to be heated. When the corrugated cardboard is heated, the rotating device is set to make the corrugated cardboard fall on the conveyor belt 1 to continue the next processing. The area between the heating box 4 and the connecting plate 15 is the gluing area for the staff. When the corrugated cardboard moves to this area, the staff will gluing and gluing the corrugated cardboard. The pasted corrugated cardboard will move to the connecting plate 15 with the movement of the conveyor belt 1. A heating roller 20 is rotatably installed between the two connecting plates 15, so that the bonded corrugated cardboard will be heated again when passing through the heating roller 20, so that the colloid gluing inside the corrugated cardboard is heated, so that each layer of the corrugated cardboard is more closely fitted. At the same time, the assembly line operation greatly improves the work efficiency of the corrugated cardboard processing.
