Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated board processing, and particularly relates to a corrugated board dryer. Background Art

[0002] Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper sandwich and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. During the production process of corrugated board, it is necessary to carry out drying processing to control the moisture content of the board, strengthen the bonding fastness, and complete the forming of the board. Most of the existing drying processing methods are realized by drying. However, drying type drying not only requires a large-volume drying oven, which occupies a large amount of factory space, but also greatly limits the drying efficiency of corrugated board due to poor air circulation. Therefore, to solve the above problems, it is necessary to develop a corrugated board dryer with reasonable structural design and good drying effect. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a corrugated board dryer with reasonable structural design and good drying effect.

[0004] The purpose of the utility model is realized as follows: A corrugated board dryer includes an installation platform, a drying box, a blowing motor, and a control box. The installation platform is horizontally arranged as a whole, and bases are fixedly arranged at both ends of its lower surface. The drying box is a square frame structure with a through groove in the center, horizontally and fixedly placed above the installation platform. In the middle of the right opening of the drying box, two air ducts are longitudinally arranged. The two air ducts are arranged in a flat shape, and a corrugated board discharge channel is formed between them. Multiple high-pressure nozzles are fixedly communicated with the left side surface of the air duct. Multiple infrared heating tubes are longitudinally and fixedly arranged on the inner top surface of the drying box, and an electric heating block is horizontally and fixedly arranged at the center of the inner bottom surface. A conveying assembly is horizontally arranged at the front end and the rear end of the electric heating block. The conveying assembly consists of a driving sprocket, a driven sprocket, and a conveying chain. The driving sprocket and the driven sprocket are respectively fixedly installed at the left end and the right end of the inner bottom surface of the drying box through brackets, and the conveying chain is annularly sleeved outside the driving sprocket and the driven sprocket. The blowing motor is located at the right end of the upper surface of the drying box, and its air outlet channel is communicated with the air duct through a connecting pipe. The control box is fixedly arranged in the middle of the lower surface of the installation platform, and the infrared heating tubes, the driving sprocket, the electric heating block, and the blowing motor are all electrically connected to the control box through wires.

[0005] A transparent observation frame is horizontally arranged in the middle of the front end surface of the drying box.

[0006] At the middle of the front end and the middle of the rear end of the left opening of the drying oven, guiding blocks are longitudinally and fixedly arranged. At the middle position of the inner end face of the guiding block, a guiding groove is arranged. The two guiding grooves cooperate with each other to form a guiding and placing gap for corrugated cardboard.

[0007] The inner bottom surface of the guiding groove and the upper end of the conveying assembly are located on the same horizontal plane.

[0008] The beneficial effects of the present utility model: By arranging the conveying assembly, during use, the rotation of the driving sprocket drives the conveying chain to rotate, and then through the cooperation of the conveying chains in the two conveying assemblies, the horizontal and transverse conveying of corrugated cardboard from left to right is realized; by arranging the infrared heating tube and the electric heating block, through the cooperation of the infrared heating tube and the electric heating block, when the corrugated cardboard moves from left to right inside the drying oven through the conveying assembly, the upper surface and the lower surface of the corrugated cardboard can be heated respectively, improving the drying effect and increasing the drying efficiency while doing so;
