Traditional ramie stripping devices require manual feeding and reverse pulling, resulting in insufficient stripping. This is especially true when processing multiple ramie fibers, where the edges may not be fully fed in or may be squeezed, leading to incomplete stripping and reduced efficiency.
The automatic ramie stripping machine includes a stripping box, a feeding top frame, a lifting support, a stripping pressure cylinder, first and second stripping rollers, an extrusion assembly, and a pushing assembly. The pushing assembly brings the edge ramie closer to the center, and the fibers are stripped by scraping and extruding the relatively inner sides of the first and second stripping rollers. The process is carried out in a sealed environment to reduce noise and dust, ensuring stability and continuity.
It improves ramie stripping efficiency, ensures high-quality ramie fiber production, avoids equipment failure and quality degradation, protects the health of operators, and achieves an automated and stable ramie stripping process.

Description
Automatic ramie stripping machine Technical Field
[0001] This application relates to the field of ramie stripping technology, and in particular to an automatic ramie stripping machine. Background Technology
[0002] A ramie stripping machine is a specialized piece of equipment used for stripping ramie. The operator feeds the ramie stalks into the gap between the stripping roller and the pressure plate (or feed roller). The stripping roller's striking plates scrape and compress the stalks, breaking the ramie fibers and outer shell into fragments that separate from the fibers. The fibers are then gradually peeled off the stalks due to the continuous scraping and compression, and are ultimately pulled out by the operator in the opposite direction.
[0003] A search revealed that CN218580141U discloses a ramie peeling machine. The ramie to be peeled is placed on a processing table, and a peeling mechanism peels the ramie. Simultaneously, a pressing and conveying mechanism installed on the top frame presses and buffers the ramie being peeled, ensuring thorough peeling. The peeled ramie is conveyed to the bottom of the machine body under the action of the first and second peeling rollers. At the same time, while the pressing and conveying mechanism applies buffering pressure to the ramie, the ramie exerts a force on the pressing and conveying mechanism in the opposite direction. Under the action of the directional component, the conveying rollers on the pressing and conveying mechanism rotate in one direction. This causes the ramie, under the thrust generated by the threaded grooves on the conveying rollers, to slowly move the peeled ramie stalks towards the conveyor belt, which then transports the stalks out.
[0004] Regarding the aforementioned technologies, the inventors believe the following technical defects require improvement: Because this device requires manual feeding and pulling to separate the hemp fibers from the outer layer, insufficient stripping may occur due to improper manual operation or machine design flaws. Particularly when processing multiple ramie strands, if the edge ramie is not fully fed in or subjected to sufficient compression and scraping, leakage will occur, leading to insufficient stripping and reduced stripping efficiency.

The extrusion assembly 7 is installed in the middle of the feeding top frame 2.
[0035] The feeding top frame 2 is used to support the extrusion assembly 7, the stripping box 1 is used to provide a sealed environment for scraping ramie, the extrusion assembly 7 is used to push the lifting support 3, the lifting support 3, together with the stripping pressure cylinder 4, is used to press the ramie on the opposite inner side of the first stripping roller 5 and the second stripping roller 6, the first stripping roller 5, together with the second stripping roller 6, is used to scrape the ramie stems and peel off the fibers, and the pushing assembly 8 is used to bring the ramie at the edge towards the center.
[0036] The feeding assembly 8 includes an inclined bracket 81, an adjusting frame 82, an electric telescopic rod 83, a connecting piece 84, and a rotating shaft 85. The inclined bracket 81 is fixedly connected to the bottom inner side of the feeding top frame 2. The adjusting frame 82 is slidably sleeved on the outer side of the inclined bracket 81. The electric telescopic rod 83 is installed on one side of the inclined bracket 81. The surface of the connecting piece 84 is fixedly connected to the output end of the electric telescopic rod 83. The rotating shaft 85 is rotatably connected to the outer side of the adjusting frame 82.
[0037] The extrusion assembly 7 includes a push cylinder 71, a push rod 72, and a positioning slider 73. The push cylinder 71 is installed in the middle of the feeding top frame 2, the push rod 72 is fixedly connected to the outside of the output end of the push cylinder 71, and the positioning slider 73 is fixedly connected to both sides of the lifting support 3.

[0039] A blower 10 is also threadedly connected to the bottom side of the stripping box 1 near the second stripping roller 6.
[0040] A DC motor 11 is also installed on the outside of the flaking box 1. The motor shaft of the DC motor 11 is fixedly connected to one end of the first flaking roller 5 through a coupling.
[0041] A locking gear 12 is also meshed with one side of the first peeling roller 5 and the second peeling roller 6.
[0042] The stripping box 1 is located at the lower end of the first stripping roller 5 and the second stripping roller 6 and is also fixedly connected to the feeding slide 13.
[0043] The usage process of the automatic ramie stripping machine according to this application embodiment is roughly as follows:
[0044] In use, multiple ramie fibers are fed into the feeding port 14 between the first peeling roller 5 and the second peeling roller 6. Then, the pushing cylinder 71 above the feeding top frame 2 is activated, pushing the push rod 72. The push rod 72 pushes the lower lifting support 3 downwards. During this process, the positioning sliders 73 on both sides of the lifting support 3 are embedded into the limiting groove 9, allowing the lifting support 3 to smoothly move the lower ramie pressing cylinder 4 downwards on the slotted surface of the limiting groove 9, pressing the ramie fibers inside the spikes between the first peeling roller 5 and the second peeling roller 6. Simultaneously, the electric telescopic rods 83 on both sides of the tilting bracket 81 are activated, their output ends pushing the connecting piece 84. The connecting piece 84 causes the adjusting frame 82 to extend out of the tilting bracket 81. The rotating shaft 85 on the outer side of the adjusting frame 82 moves along the 30° tilting angle. The ramie fibers located at the edges converge towards the center. Then, the outer DC motor 11 is activated, and its motor shaft drives the first peeling roller 5 to rotate. Due to the meshing of the locking gear 12 between the first peeling roller 5 and the second peeling roller 6, the first peeling roller 5 and the second peeling roller 6 rotate in opposite directions under gear transmission. The spikes in the center scrape inward and pierce the ramie, allowing the ramie fibers at the edges to be fully scraped and squeezed by the first peeling roller 5 and the second peeling roller 6, thereby breaking the ramie fibers and shells into fragments and separating them from the fibers. Then, the blowing fan 10 is activated, and the scraped fragments are pushed against the inner wall of the peeling box 1 under inertia. Then, under the effect of the wind, the fibers and fragments fall into the feeding ramp 13 and finally slide out of the peeling box 1, achieving the purpose of automated ramie peeling.
[0045] The beneficial technical effects of the automatic ramie stripping machine according to the embodiments of this application are roughly as follows:
[0046] The ramie stalks are effectively scraped and the fibers are separated by the relative inner cooperation of the first peeling roller 5 and the second peeling roller 6. This design improves peeling efficiency and ensures high-quality ramie fiber output. The peeling box 1 provides a sealed environment for scraping ramie, which helps reduce noise and dust during processing, protects the health of operators, and maintains the stability and continuity of the peeling process. The feeding top frame 2 supports the extrusion assembly 7, which not only ensures the stable operation of the extrusion assembly 7, but also allows for flexible adjustment of the peeling process as needed. On the other hand, the design of the pushing assembly 8 can bring the ramie at the edge towards the center, ensuring a uniform distribution of ramie between the peeling rollers. This not only improves peeling efficiency, but also avoids equipment failure or reduced peeling quality caused by uneven ramie distribution.
[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
