Description

Technical Field

[0001] This utility model relates to the field of bamboo product processing technology, specifically to a multi-layer drying machine for multi-specification heavy bamboo fibers. Background Technology

[0002] Reconstituted bamboo filaments are a new type of bamboo material that is reorganized and reinforced. Specifically, reconstituted bamboo filaments are made by processing bamboo into long strips, filaments, or crushing them into bundles, drying them, impregnating them with resin, drying them again to the required moisture content, and then laying them in a mold for high-temperature and high-pressure thermosetting to form profiles.

[0003] In the processing of reconstituted bamboo fibers, drying equipment is required. Existing reconstituted bamboo fiber drying equipment directly feeds the bamboo fibers into the drying room via a conveyor. The conveyed bamboo fibers are not neat enough, which affects the drying effect. The conveyor cannot meet the feeding requirements of different specifications, and the number of drying layers is limited, which does not meet production needs. Utility Model Content

[0039] A multi-layer drying machine for multi-specification heavy bamboo fibers

[0040] The working principle of this utility model is as follows: Based on the specifications and drying requirements of the reconstituted bamboo fibers, when using a multi-layer drying system, an electric winch lowers the feeding end of the feeding frame and the feeding conveyor to the front of the feeding end of the third-layer drying conveyor. The positions of the two positioning plates are adjusted according to the specifications of the reconstituted bamboo fibers to position the feeding position. Then, the reconstituted bamboo fibers to be dried enter from the feeding end of the feeding conveyor and are conveyed towards the feeding end of the first-layer drying conveyor. During this process, the feeding alignment cylinder of the feeding alignment component pushes the feeding alignment push plate towards the reconstituted bamboo fibers for alignment. After entering the drying chamber through the feeding end of the first-layer drying conveyor, the fibers then fall from the discharge end of the first-layer drying conveyor into the second-layer drying conveyor. The material enters from the feed end of the device, then falls from the discharge end of the second-layer drying conveyor to the feed end of the third-layer drying conveyor, and is then fed into the unloading device from the output end of the third-layer drying conveyor. During this process, the drying chamber alignment cylinder of the drying chamber alignment component drives the rotating shaft to rotate, and the corresponding alignment plates align the heavy bamboo fibers on each layer. When only one layer of drying is needed, the feed end of the feeding frame and the feeding conveyor is raised to the highest position by an electric winch. Then, the heavy bamboo fibers to be dried enter from the feed end of the third-layer drying conveyor, are aligned by the drying chamber alignment component, and are sent into the drying chamber for drying. After that, they are directly fed into the unloading device from the output end of the third-layer drying conveyor.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model.
