Description

Technical Field

[0001] This invention relates to the field of plant fiber extraction technology, specifically to a plant fiber extraction system. Background Technology

[0002] Common agricultural waste (such as pineapple leaves, banana stems, sisal, and agave) is usually disposed of by discarding or composting. However, this type of agricultural waste contains abundant plant fibers, which can be converted into reusable fiber raw materials for use in the textile industry, such as scarves, clothing, and hats. This can significantly reduce the amount of agricultural waste piled up, decrease air pollution caused by combustion, and increase the utilization value of fibers, making agricultural waste an economically beneficial green resource.

[0003] However, existing plant fiber extraction devices cannot provide a one-stop solution for clamping, fiber extraction, and sorting during the transport and extraction of plant leaves and leaf fibers.

[0004] Therefore, providing a more comprehensive plant fiber extraction system is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a plant fiber extraction system to realize one-stop fiber extraction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Plant fiber extraction system, including: An assembly and feeding unit is used for placing and arranging plant leaves; A clamping and conveying unit is arranged side by side on one side of the assembly and feeding unit for clamping and conveying the front part of plant leaves. The roller scraping unit is located opposite the gripping and conveying unit to receive the plant leaves conveyed by the gripping and conveying unit and to provide a leaf scraping action to separate leaf skin, leaf mud, impurities and fibers. The clamping point cutting unit is used to cut and separate the plant fiber segments that are still connected after being scraped by the roller scraping unit from the front part of the plant leaf. The waste material processing unit is used to collect the residue and the front part of the plant after scraping, and then process them into organic feed through vacuum treatment; the plant fiber segments are collected and dried to form finished plant fiber products.

[0008] Furthermore, the clamping and conveying unit includes a base and an upper conveyor belt and a lower conveyor belt pivotally mounted on the base. The upper conveyor belt is pivotally connected to an upper clamping seat, which has an upper groove and an upper clamping edge. The lower conveyor belt is pivotally connected to a lower clamping seat, which has a lower groove and a lower clamping edge. The total length of the lower conveyor belt from the inlet to the outlet is greater than the total length of the upper conveyor belt, so that the lower conveyor belt is located below the inlet to form a buffer section.

[0009] Furthermore, the upper groove is located at the position of the lower clamping edge, and the upper clamping edge is located at the position of the lower groove. A concave-convex clamping structure is formed between the upper clamping seat and the lower clamping seat to clamp and transport the front part of the plant leaf.

[0010] Furthermore, the upper edge and the lower edge can be any one of triangle, rectangle, circle and serrated.

[0011] Furthermore, the roller scraping unit includes a horizontal roller with a conical front end. Multiple equally spaced movable scrapers are fixed on the outer diameter of the horizontal roller. A blower assembly is provided at the end of the horizontal roller away from the conical body and can rotate with the horizontal roller. Multiple blades are fixed on the outer diameter of the blower assembly. An arc-shaped guide plate is provided at a relative position on the outer diameter of the horizontal roller, and a scraping space is formed between the inner surface of the arc-shaped guide plate and the outer diameter of the horizontal roller.

[0012] Furthermore, the top of the movable scraper is provided with a scraping blade, which can be any geometric angle, such as a sharp angle or an oblique angle.

[0013] Furthermore, the inner surface of the arc-shaped guide plate is provided with an inward concave arc corresponding to the outer diameter of the horizontal roller.

[0014] Furthermore, all the blades are bent, and multiple blades are arranged at equal intervals, with the extension direction of each blade parallel to the axis of the horizontal drum.

[0015] Furthermore, the arc-shaped guide plate is locked to the machine base by an adjusting seat, which is movable up and down on the machine base by bolts to adjust the gap size of the fiber scraping space.

[0016] Furthermore, the cutting assembly is located at one end of the machine base near the discharge port.

[0017] Therefore, the present invention provides a plant fiber extraction system, which, compared with the prior art, has the following beneficial effects: 1) The clamping and conveying unit is used to clamp and convey the front part (stem) of plant leaves. The fiber scraping unit receives the plant leaves and provides the leaf scraping action to separate the leaf skin, leaf mud, impurities and fibers. The cutting group cuts the connection between the moving plant fibers and the front part (stem) of the leaves to realize one-stop fiber picking operation. 2) Due to the concave arc of the inner surface of the arc-shaped guide plate, the scraped leaf bark, leaf pulp and impurities fall and are collected. The plant fibers are cut by the cutting group and fall to the fiber collection area, while the front part of the leaf (stem) is held and transported to the receiving section by the upper and lower conveyor belts, and then falls from the discharge port to the residue collection area to achieve automatic classification and collection. 3) The scraped leaf pulp, leaf bark, impurities, and the front part (stem) of the plant are collected and vacuum-processed to make organic feed. The plant fiber is collected separately and dried to form a finished plant fiber product, so that the plant leaves can be completely reused. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-6 As shown, this embodiment of the invention discloses a plant fiber extraction system, comprising: The assembling and feeding unit 1 is used for placing and arranging plant leaves; in this embodiment, the assembling and feeding unit 1 can be a manual workbench, a roller conveyor belt, or a robotic arm. A clamping and conveying unit 2 is arranged side-by-side on one side of the assembly and feeding unit 1 for clamping and conveying the front part (stem) of plant leaves. In this embodiment, the clamping and conveying unit 2 includes a base 21 and an upper conveyor belt 22 and a lower conveyor belt 23 pivotally mounted on the base 21. The upper conveyor belt 22 is pivotally connected to an upper clamping seat 221, which has an upper groove 222 and an upper clamping edge 223. The lower conveyor belt 23 is pivotally connected to a lower clamping seat 231, which has a lower groove 232 and a lower clamping edge 233. The upper clamping edge 223 and the lower clamping edge 233 can be triangular, rectangular, circular, or serrated. The upper groove 222 is located corresponding to the lower clamping edge 233, and the upper clamping edge 223 is located corresponding to the lower groove 232. The upper clamping seat 221 and the lower clamping seat 231 form a concave-convex clamping structure for clamping and conveying the front part (stem) of the plant leaf. The total length of the lower conveyor belt 23 from the inlet 24 to the outlet 25 is greater than the total length of the upper conveyor belt 22. The lower conveyor belt 23 is located below the inlet 24 to form a buffer section 26, which receives the plant leaves arranged and placed on the buffer section 26 by the operator. The plant leaves then enter the concave-convex clamping structure of the upper clamping seat 221 and the lower clamping seat 231 in sequence, so that the plant leaves can smoothly enter the clamping and conveying unit 2. A roller scraping unit 3 is positioned opposite the gripping and conveying unit 2 to receive plant leaves from the gripping and conveying unit 2 and to scrape the leaves, separating leaf skin, leaf pulp, impurities, and fibers. In this embodiment, the roller scraping unit 3 includes a horizontal roller 31 with a conical front end 311. Multiple equally spaced movable scrapers 312 are fixed to the outer diameter of the horizontal roller 31, each with a scraping blade 313 at its tip, which can be a sharp angle or a bevel. A blower assembly 314 is located at the end of the horizontal roller 31 away from the conical body 311 and rotates with the horizontal roller 31. Multiple blades 31 are fixed to the outer diameter of the blower assembly 314. 5. All blades 315 are bent, and multiple blades 315 are arranged at equal intervals, with the extension direction of each blade 315 parallel to the axis of the horizontal roller 31. An arc-shaped guide plate 32 is provided at a position relative to the outer diameter of the horizontal roller 31. The inner surface of the arc-shaped guide plate 32 has an inward concave arc corresponding to the outer diameter of the horizontal roller 31. A scraping space 33 is formed between the inner surface of the arc-shaped guide plate 32 and the outer diameter of the horizontal roller 31. The scraping space 33 allows plant leaves to enter, and the movable scraper 312 scrapes them. The arc-shaped guide plate 32 is locked to the machine base 21 by an adjusting seat 321. The adjusting seat 321 is movable up and down on the machine base 21 by bolts 322 to adjust the gap size of the scraping space 33 to provide scraping operations for blades of different thicknesses. The clamping and cutting unit 4 has a cutting group 41 for cutting and separating the plant fiber segments that are still connected after being scraped by the roller scraping unit 3 from the front part (stem) of the plant leaf; in this embodiment, the cutting group 41 is located at one end of the machine base 21 near the discharge port 25. The waste material processing unit 5 is used to collect the scraped residue (leaf mesophyll, leaf bark, impurities) and the front part of the plant (stem), and then process them into organic feed through vacuum treatment; the plant fiber segments are collected and dried to form finished plant fiber products. Specifically, the plant leaves are scraped by the roller scraping unit 3, which separates the scraped residue (leaf bark, leaf mud, impurities) from the fibers, and the fibers are collected by the arc-shaped guide plate 32; while the plant fiber segments are cut by the cutting group 41, and the plant fibers fall into the fiber collection area A set below the cutting group 41, while the front part of the plant (stem) is output from the discharge port 25 and collected by the residue collection area B, so that the plant fiber segments and the front part of the plant (stem) are collected separately.

[0023] Based on the above embodiments, the present invention has the following beneficial effects: 1) The front part (stem) of the plant leaf is clamped and conveyed by the clamping and conveying unit 2. The roller fiber scraping unit 3 receives the plant leaf clamped and conveyed by the clamping and conveying unit 2 and provides the leaf scraping action to separate the leaf skin, leaf mud, impurities and fibers. The cutting group 41 cuts the connection between the moving plant fiber and the front part (stem) of the leaf, realizing one-stop fiber picking operation. 2) Guided by the concave arc of the inner surface of the arc-shaped guide plate 32, the scraped residue (leaf bark, leaf pulp and impurities) can fall and be collected. The plant fiber falls to the fiber collection area A through the cutting group 41, while the front part of the leaf (stem) is conveyed to the receiving section by the clamping of the upper conveyor belt 22 and the lower conveyor belt 23, and then falls to the residue collection area B from the discharge port 25, thus achieving automatic classification and collection. 3) Organic feed is produced by collecting scraped leaf mesophyll, leaf bark, impurities, and the front part (stem) of the plant and processing them through vacuum. The plant fiber is collected separately and dried to form a finished plant fiber product, so that the plant leaves can be completely reused.

[0024] In summary, this invention achieves complete reuse of plant leaves by separating them into finished plant fiber products and organic feed products through one-stop clamping, fiber scraping, cutting, and sorting collection.
