Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of special non-woven fabric production industry, in particular to a brown skin leftover fiber opening device. BACKGROUND

[0002] As known in the industry, the fiber in the brown skin is a natural and healthy wood fiber, which is widely used in the market. This kind of fiber body is an excellent material for making cushion, mattress and other cushion materials. However, after using these fibers, there are still a lot of leftover materials (tailings) connected by brown fibers. The current processing method is to use an opening device to open the fibers in the leftover materials multiple times. The processing device is shown in Figure 10 When the leftover material enters the opening roller H1 of the opening device from the inlet Q for the first time (the gap between the pair of H1 opening rollers in the figure is the largest), it enters the next set of opening rollers H2 for the second time through the conveying device (the gap between the pair of H2 opening rollers is smaller than the gap between the pair of H1 opening rollers). In this way, the gap between H3 and H4 opening rollers gradually decreases. After being opened by the continuous four sets of opening beaters, the opening task of the brown skin leftover fiber is completed. However, since the equipment used in this kind of leftover material 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 small diameter are even crushed. This seriously affects the product quality and the production rate. Therefore, an improved device is needed to solve the above problems. The present application only needs to be opened once to achieve satisfactory opening effect. Therefore, the damage to the fiber during the opening process is small, the strength of the opened brown fiber is higher, the length is longer, the production efficiency, the grade rate and the production rate are obviously higher than those of the conventional leftover material opening equipment. This device not only has small damage to the fiber during the opening process, but also greatly reduces the equipment size. SUMMARY

The position is accurate during the opening and supplementing of the material, and the opening effect is good. BRIEF DESCRIPTION OF DRAWINGS
