Description

Technical Field

[0001] The invention relates to the technical field of special non-woven fabric production industry, in particular to a fiber loosening device for brown leather scraps. Background Art

[0002] As known in the industry, the fiber in the palm bark is a natural and healthy wood fiber, which is widely used in the market. This type of fiber is an excellent material for making cushions, mattresses and other cushion materials. However, after using these fibers, there are still a lot of leftovers (tailings) of palm fibers connected together. The current processing method is to use an opening device multiple times to loosen the fibers in the leftovers. The processing device is as follows: Fig.10 As shown; when the scraps enter the opening roller H1 of the opening device from the entrance Q for one opening (the gap between a pair of H1 opening rollers is the largest in the figure), they enter the next set of opening rollers H2 through the conveying device for a second opening (the gap between a pair of H2 opening rollers is smaller than the gap between a pair of H1 opening rollers), and so on, the gap between the H3 and H4 opening rollers gradually decreases. After more than four sets of continuous opening by open beater devices, the task of opening the fibers of the brown leather scraps is completed. However, since the equipment used in this type of scrap opening device is multiple opening, the length of the brown fiber after opening is very short (only low-grade products can be made), and many fibers with finer fineness are even crushed. This seriously affects the product quality and the product production rate, so a device is needed to improve it in view of the above problems. The present invention only needs one opening to achieve a satisfactory opening effect. Therefore, there is little damage to the fibers during the opening process. The palm fibers after opening are stronger and longer. The production efficiency, grade rate and completion rate are significantly higher than those of conventional scrap opening equipment. This device not only causes little damage to the fibers during the scrap opening process, but also greatly reduces the size of the equipment. Summary of the invention
