Technical Field
[0001] The present invention relates to the technical field of corrugated cardboard processing, and in particular to a corrugated cardboard drying device. Background Art
[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated paper core and one layer of cardboard. Corrugated cardboard has high mechanical strength and can withstand collisions and falls during transportation, and is widely used in the packaging industry.
[0003] Since the interlayer, lining paper and face paper of the corrugated cardboard are usually bonded together with glue, a drying device is required to dry the corrugated cardboard so that the glue solidifies and the interlayer, lining paper and face paper are firmly bonded together.
[0004] At present, the existing technology uses ventilation heating and drying to dry the corrugated paper. However, for the current corrugated paper production market, ordinary heating and drying cannot effectively solve the drying process of large-scale production of corrugated paper, resulting in a long drying time process affecting the production progress, and uneven drying resulting in an uneven surface of the corrugated paper affecting product quality. Based on this, the present application proposes a corrugated paperboard drying equipment to solve the above problems. Utility Model Content

After the corrugated cardboard is placed on the support tubes 3, the contact area between the two is small, and the area affected by drying is small, thereby ensuring the drying effect, and the corrugated cardboard can be placed on the multiple layers of support tubes 3, so that multiple cardboards can be dried at the same time. A heating box 2 is installed above the drying box 1, and a heating device 24 is installed inside the drying box 1, which provides the device with heat required for drying. A fan 9 is installed inside the heating box 2, and the heating box 2 is connected to the plurality of support tubes 3 through a pipeline 7. The fan 9 fills hot air into the support tubes 3. After the support tubes 3 are heated, the temperature rises, and the cardboard can be heated. Three groups of air holes are opened on the support tubes 3, and the three groups of air holes are respectively located on both sides and the bottom, so that the drying box 1 is evenly filled with hot air, and each position of the cardboard can be dried, thereby ensuring the drying efficiency.
[0037] The cardboard can move on the support tube 3. The inner side of the bend of the support tube 3 is rotatably installed with a rolling wheel 11. After the rolling wheel 11 contacts the cardboard, it can drive the cardboard to move backward. Through the movement of the cardboard, various positions of the cardboard can be dried and cyclic heating can be achieved.
[0038] A reciprocating clamping plate 12 is installed above the bending part of the support tube 3. The clamping plate 12 can guide the movement of the cardboard to prevent it from deflecting during movement, so as to ensure that it can move smoothly.
