Description

Technical Field

[0001] The utility model relates to the field of packaging boxes, in particular to a packaging box cardboard drying device. Background Art

[0002] Most packaging boxes are made from corrugated cardboard. Corrugated cardboard is a sheet of corrugated paper, formed by bonding together corrugated sheets such as facesheets and core paper, which are processed by corrugating rollers. It possesses high mechanical strength, capable of withstanding collisions and falls during transportation. However, after being manufactured, the corrugated cardboard often contains a certain amount of moisture. If not dried promptly, the compressive strength of the corrugated cardboard decreases. Existing equipment for drying cardboard for packaging boxes generally only allows for single-sided drying, resulting in poor results and low efficiency, necessitating urgent improvements. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a packaging box cardboard drying device, including a barrel body and a barrel cover, wherein a cardboard is rotatably provided in the barrel body, a plurality of clamping blocks are circumferentially arranged on the top edge of the cardboard, a cardboard groove is opened on the clamping block, a ventilation pipe is fixedly provided at the center of the cardboard, an air inlet is provided at the top of the ventilation pipe, a plurality of exhaust grooves are opened circumferentially on the side wall of the ventilation pipe, and a plurality of exhaust holes are opened below the side wall of the barrel body.

[0005] The packaging box cardboard drying device provided by the utility model also has the following technical features:

[0006] Furthermore, a driving assembly for driving the ventilation pipe to rotate is fixedly provided on the top of the barrel cover, and the driving assembly includes a frame fixedly connected to the barrel cover, a motor fixed on the frame, a driving gear fixedly connected to the output shaft of the motor, and a driven ring gear meshing with the driving gear, and the driven ring gear is fixedly arranged coaxially with the ventilation pipe.

[0007] Furthermore, two adjacent clamping blocks on a straight line form a group.

[0008] Furthermore, the barrel body and the barrel cover are connected by bolts.

[0009] Furthermore, a bearing ring is installed between the barrel cover and the vent pipe.

[0010] Furthermore, a handle is symmetrically fixed on the top of the barrel cover.

[0011] Furthermore, a groove is fixedly provided on the bottom wall of the barrel body, and a central column that cooperates with the groove is fixedly provided on the bottom of the cardboard.

[0012] The utility model has the following beneficial effects: first, multiple cardboards to be dried are vertically clamped into the cardboard slots on the clamping block, and then hot air is introduced into the ventilation pipe from the air inlet, so that the hot air is evenly dispersed to the surroundings from the exhaust slot and discharged from the exhaust hole, so that the multiple cardboards are evenly dried and the drying effect is better.
