Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard shaping and drying technology, specifically to an energy-saving corrugated cardboard shaping and drying device. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. 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. In modern life, adhesives are used in the production of corrugated cardboard, and the finished product often contains a certain amount of moisture, which requires the use of corrugated cardboard shaping and drying equipment.

[0003] For example, Chinese patent application CN202210647937.2 discloses an energy-saving corrugated cardboard shaping and drying device, which includes a frame and corrugated cardboard. The frame is equipped with a conveying mechanism, a heating mechanism, and a collecting mechanism. The heating mechanism includes a hot air blower, and an regulating box is connected to the air outlet of the hot air blower. The regulating box contains an air volume regulating component, which includes an regulating wheel. A baffle is fixed inside the regulating box, and an air inlet chamber and an air outlet chamber are formed on both sides of the baffle. An opening is provided on the baffle, and a slidable blocking block is provided on one side of the opening. A slide rail is fixed on the block, and a slidable slider is embedded in the slide rail. The lower end of the slider is fixedly connected to the upper end of the blocking block, and a rack is fixedly provided on the upper end of the slider, which meshes with the regulating wheel. A rotating motor is installed on one side of the regulating box, and the output shaft of the rotating motor passes through the regulating box and is fixedly connected to one end of the regulating wheel. An air duct is connected to the upper side of the regulating box. This invention has a reasonable structure and the advantage of high drying efficiency.

[0004] However, in actual use, the above device only dries the moisture on the top of the corrugated cardboard through the air duct on the upper side of the regulating box. However, the moisture will accumulate at the bottom of the corrugated cardboard to a certain extent, which will affect the quality of the bottom of the corrugated cardboard and reduce the efficiency and quality of the overall shaping and drying of the corrugated cardboard.

A feeding frame 2 is fixedly installed on one side of the top of the U-shaped body 1. The feeding frame 2 has a discharge port 6 at the bottom of the side of the side of the U-shaped body 1, and the side of the discharge port 6 is flush with one end of the roller conveyor 3. A guide plate 8 is fixedly installed on the other side of the U-shaped body 1, and one end of the guide plate 8 is located at the bottom of the other end of the roller conveyor 3 to facilitate the discharge of the dried corrugated cardboard. The four corners of the bottom of the U-shaped body 1 are all fixed with movable wheels 9 to facilitate the movement of this utility model.

[0025] like Figure 1-4 As shown, the top of the U-shaped machine body 1 is equipped with a drying component 5, which is used to perform comprehensive shaping and drying of the corrugated cardboard after production, so as to avoid reducing the efficiency and quality of the shaping and drying of the corrugated cardboard. The drying component 5 includes a first hot air blower 51, which is fixedly installed at the top center of the U-shaped machine body 1. A receiving frame 52 is embedded in the bottom of the inside of the U-shaped machine body 1. A second hot air blower 53 is fixedly installed at the bottom of the inside of the receiving frame 52. Several evenly distributed air outlets 56 are opened on both sides of the receiving frame 52. A first guide plate 57 is fixedly installed on both sides of the bottom of the second hot air blower 53. The first guide plate 57 is fixedly installed at the bottom of the inside of the receiving frame 52. A hollow frame 54 is fixedly installed at the top center of the receiving frame 52. A filter screen 55 is fixedly installed at the bottom of the inside of the hollow frame 54. The hollow frame 54 is located at the bottom of the roller conveyor 3, so that the moisture dried by the first hot air blower 51 can pass through the filter screen 55 and fall off.

[0026] The hollow frame 54 is fixedly provided with two second guide plates 510 on both sides. The two second guide plates 510 are respectively fixed between the two sides inside the U-shaped body 1, so that the water dried by the first hot air blower 51 can be guided through the second guide plates 510. The bottom of the receiving frame 52 is fixedly provided with two drainage pipes 58 distributed front and back.
