Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a hot pressing device for cardboard processing. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. When processing corrugated cardboard, a hot pressing laminating machine is used to perform hot pressing operations on the cardboard.

[0003] Most of the hot pressing devices for cardboard processing on the market are prone to dust and impurities on the surface of the cardboard before hot pressing, which will affect the pressing effect. When the hot pressing plate leaves the corrugated cardboard during hot pressing, it drives the top surface of the corrugated cardboard to move, which may cause the board surface to warp after hot pressing. The cardboard after hot pressing is not easy to dry, which means that the hot pressing devices for cardboard processing need to be improved. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions: A hot pressing device for cardboard processing, comprising a hot pressing seat, the upper end of which is fixedly connected to a limiting bracket, and a processing structure is provided on the limiting bracket.

[0006] The jack-up plate is fixedly mounted on the support frame, and the support frame is connected with the support structure to form a circle, and the jack-up plate is fixedly mounted on the support frame to form a circle.

[0007] There are four pressure plates, which are symmetrically distributed on the outside of the pressure plate.

[0008] It should be noted that the fan on board is an electric fan.

[0009] Furthermore, a belt conveyor is provided on the limiting bracket, and a collection box is provided at the upper end of the hot pressing seat near the limiting bracket.

[0010] A collecting trough is provided in the collecting box, and the collecting trough can receive the cardboard dropped from the belt conveyor 4 .

[0011] Furthermore, a movable hole is opened in the pressing plate, and the movable plate passes through the pressing plate through the movable hole.

[0012] Furthermore, a ventilation hole is opened in the pressure plate, and the pressure plate is connected to the fan through the ventilation hole.

[0013] Among them, the pressure plate is in the shape of a hollow cylinder.

[0014] Furthermore, a first circular hole is provided in the limiting partition, and a second circular hole is provided in the pressing plate.

[0039] In this embodiment, the structures in the processing structure are all distributed based on the symmetrical structure of the hot pressing seat 1.

[0040] The working principle of the above embodiment is:

[0041] First, the limiting bracket 2 is fixed by the hot pressing seat 1, the belt conveyor 4 is limited by the limiting bracket 2, and the cardboard to be processed is conveyed by the belt conveyor 4.

[0042] Secondly, when the cardboard is transported to the appropriate position, the driving motor 12 drives the connecting frame 14 to rotate and displace, and the rotating connecting frame 14 drives the pressure rod 16, the fan 17 and the pressure plate 18 to move out from under the heating plate 7. At this time, the cylinder 5 drives the pressure plate 6 to move, and the displaced pressure plate 6 drives the heating plate 7 to perform hot pressing on the cardboard on the belt conveyor 4.

[0043] Finally, before the cardboard is processed, the cylinder 5 is operated to drive the pressing plate 6 to move close to the cardboard, and the connecting frame 14 is driven to rotate by the driving motor 12. The rotating connecting frame 14 drives the pressing rod 16 to move, and the displaced pressing rod 16 can drive the fan 17 to move, and the fan 17 can adjust the use angle through the electric telescopic rod 15. At this time, the fan 17 can clean the dust on the surface of the cardboard placed on the belt conveyor 4. When the dust on the cardboard is cleaned, the fan 17 is reset by the electric telescopic rod 15. At this time, the pressure plate 18 is perpendicular to the cardboard. Before the heating plate 7 performs hot pressing on the cardboard surface, the connecting frame 14 is driven to rotate and move by the driving motor 12. The rotating connecting frame 14 drives the pressing rod 16, the fan 17 and the pressure plate 18 to move out from under the heating plate 7. When the heating plate 7 is close to the cardboard surface After the surfaces are fitted, the pressure plate 18 can perform anti-warping treatment on the surface of the cardboard, and the pressure plate 18 moves together with the movable plate 13, and the movable plate 13 is limited in the pressure plate 6 by the limiting partition 8 and the telescopic spring 10. Therefore, after the pressure plate 18 contacts the cardboard, when the heating plate 17 is still displaced, the pressure plate 18 can always contact the cardboard by lifting the movable rod 9. When the cardboard processing is completed, the cylinder 5 drives the pressure plate 6 and the heating plate 7 to lift. At this time, the cardboard surface is dried by the fan 17, and the connecting frame 14 is driven to rotate by the driving motor 12. The rotating connecting frame 14 drives the pressure rod 16 to move. The displaced pressure rod 16 can drive the fan 17 to move, and the fan 17 can adjust the use angle through the electric telescopic rod 15. At this time, the fan 17 can quickly dry the surface of the cardboard placed on the belt conveyor 4.
