Technical Field
[0001] This utility model relates to the field of fire grass processing equipment technology, specifically, to a device for peeling fire grass fibers. Background Technology
[0002] Fire grass, scientifically known as *Hylocereus undatus*, is a unique plant resource widely distributed in the high-altitude mountainous areas of Yunnan and Sichuan provinces. The white downy hairs on the underside of its leaves, after a series of processes such as fiber stripping, hand-twisting, and weaving on a waist loom, can be used to produce textiles with natural waterproof, breathable, and warm properties. This fire grass weaving technique has a profound cultural heritage in the ethnic minority regions of southwestern my country and is an important carrier of local material culture.
[0003] However, the process of fire grass weaving is quite complex, requiring dozens or even hundreds of steps, almost all of which are currently done entirely by hand. This manual production method results in long production times, high costs, and small quantities of fire grass fabrics, severely limiting the inheritance and development of the fire grass weaving technique.
[0004] Especially in the first step of fire grass weaving—twisting the white downy hairs on the back of the leaves after harvesting fire grass from the field—this process is currently entirely done by hand, without any machine assistance. Because fire grass is harvested mainly from June to August each year, and the harvest volume is large each time, but the twisting speed is slow and there are few people skilled in twisting, fire grass resources are wasted, the harvest volume is limited, and it cannot be fully utilized. This problem seriously restricts the output and quality of fire grass woven fabric in later stages. Utility Model Content
[0005] The purpose of this invention is to provide a device for peeling the fluff from fireweed, in order to solve the problem mentioned in the background art that the step of tearing and twisting the white fluff on the back of the leaves of fireweed after it is collected from the field is currently done entirely by hand without any machine assistance.
[0006] To achieve the above objectives, this utility model provides a device for stripping the fluff from fireweed, comprising a platform on which fireweed is placed. A lifting pressure plate presses and positions the two edges of the fireweed, and a thread-raising device located at the top of the fireweed end scrapes up the fluff. The fluff thread ends are then manually placed on a twisting device for twisting. A first lifting screw slide and a second lifting screw slider are respectively installed on both sides of the platform. The first lifting screw slide drives the thread-raising device to move up and down, and the second lifting screw slider drives the lifting pressure plate to move up and down.
[0007] Preferably, the top of the platform is provided with a negative pressure air vent, which consists of several small holes, and the bottom of the negative pressure air vent is equipped with several negative pressure fans for adsorbing and adhering the fire grass to the platform.
[0008] Preferably, the twisting device includes an upper crossbar and a lower crossbar, the ends of which are fixed to the outer shell of the first lifting screw slide. An upper roller is rotatably mounted on the upper crossbar via a bearing, and a lower roller is rotatably mounted on the lower crossbar via a bearing. A hand crank is mounted on the upper roller. The upper and lower rollers clamp the straw fluff, and the twisting operation is performed by driving the upper roller to rotate through the hand crank.
[0009] Preferably, the wire-raising device includes a transverse screw slide, one end of which is fixed to the slide of a first lifting screw slide. A wire-raising scraper is installed at the lower slide of the transverse screw slide. The height of the wire-raising scraper is adjusted by the first lifting screw slide, and the horizontal movement of the transverse screw slide scrapes up the fluff on the surface of the fire grass end.
[0010] Preferably, the first lifting screw slide, the second lifting screw slider, and the transverse screw slide are all driven by a motor.
[0011] Preferably, the bottom of the lifting pressure plate is equipped with several pressure rollers, which are arranged at equal intervals.
[0012] Preferably, the wire scraper is inclined, with its bottom end close to the upper surface of the fire grass.
[0013] Preferably, the pressure roller is made of silicone material with elastic deformation effect.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In this device for stripping fire grass fluff, the edges of both sides of the fire grass are pressed and positioned by a lifting pressure plate, and the fire grass fluff is automatically scraped up by a thread-raising device. The thread-twisting device is used to perform thread-twisting operations, which greatly reduces the time of manual operation, significantly improves the speed of fire grass fluff stripping and thread-twisting, and effectively solves the problem of low production efficiency of traditional manual operation.
[0016] The scraper in the device can precisely control the force and angle of scraping the pile, ensuring that the pile is scraped up evenly and completely, avoiding the breakage or residue of the pile that may be caused by uneven force or improper angle during manual operation, thus ensuring the quality and consistency of the pile thread ends.
[0017] Traditionally, the stripping and twisting of fireweed fibers are done entirely by hand, which is labor-intensive. This device, through mechanized operation, greatly reduces the operator's workload and improves work comfort and efficiency.
[0018] Because the equipment improves production efficiency, it can process more fire grass during the fire grass harvesting season, making full use of fire grass resources and avoiding waste caused by untimely processing.
[0019] The emergence of this device provides modern technical support for the fire grass weaving technique, enabling this traditional craft to be inherited and developed more efficiently, and laying a solid foundation for the production and promotion of fire grass textiles.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a device for peeling the downy fibers of fireweed, such as... Figures 1-3As shown, the system includes a platform 1, on which firewood is placed. A lifting pressure plate 5 presses and positions the firewood at its two edges. A thread-raising device 3, located at the top of the firewood end, scrapes up the firewood fluff. The fluffy thread ends are then manually placed on a twisting device 2 for twisting. A first lifting screw slide 4 and a second lifting screw slider 6 are respectively installed on both sides of the platform 1. The first lifting screw slide 4 drives the thread-raising device 3 to rise and fall, while the second lifting screw slider 6 drives the lifting pressure plate 5 to rise and fall. The platform 1 serves as the base for placing the firewood, and the lifting pressure plate 5, in conjunction with the lifting pressure plate 5, presses and positions the firewood at its two edges, ensuring the stability of the firewood during processing and preventing uneven peeling or fluff breakage caused by firewood movement or shaking. Simultaneously, the thread-raising device 3, located at the top of the firewood end, can precisely scrape up the firewood fluff. Driven by the first lifting screw slide 4, the thread-raising device 3 can be flexibly adjusted to accommodate firewood of different thicknesses or textures, further improving the accuracy and efficiency of the peeling process.
[0027] The stripped fluffy ends are then manually placed on the twisting device 2 for twisting. This step is made possible by the overall coordination and convenience of the device's design. The first lifting screw slide 4 and the second lifting screw slider 6, installed on both sides of the platform 1, provide stable lifting power for the entire device, ensuring that the thread lifting device 3 and the lifting pressure plate 5 can move accurately and smoothly, thus guaranteeing the smooth progress of the fluff stripping process.
[0028] In summary, the device for stripping fire grass fibers of this utility model achieves efficient and stable stripping of fire grass fibers through the coordinated action of the platform 1, lifting pressure plate 5, thread raising device 3, thread twisting device 2, first lifting screw slide 4 and second lifting screw slider 6, providing strong technical support for the inheritance and development of fire grass weaving techniques.
[0029] In this embodiment, a negative pressure vent 11 is provided at the top of the platform 1. The negative pressure vent 11 consists of several small holes, and several negative pressure fans 12 are installed at the bottom of the negative pressure vent 11 to adsorb and adhere the fire grass to the platform 1. This design allows the negative pressure fans 12 to generate suction through the negative pressure vent 11 when they are working, firmly adsorbing and adhering the fire grass to the platform 1. In this way, the fire grass will not move due to external force or operation during processing, ensuring the accuracy and stability of the fire grass fluff peeling.
[0030] Specifically, the twisting device 2 includes an upper crossbar 21 and a lower crossbar 22. The ends of the upper crossbar 21 and the lower crossbar 22 are fixed to the outer shell of the first lifting screw slide 4. An upper roller 23 is rotatably mounted on the upper crossbar 21 via bearings, and a lower roller 24 is rotatably mounted on the lower crossbar 22 via bearings. A hand crank 25 is mounted on the upper roller 23. The upper roller 23 and the lower roller 24 clamp the fireweed fluff, and the upper roller 23 is rotated by the hand crank 25 to perform the twisting operation. This structure allows the upper roller 23 and the lower roller 24 to clamp the fireweed fluff, and the upper roller 23 is rotated by the hand crank 25 to achieve the twisting operation. This design facilitates manual operation and ensures the efficiency and quality of twisting.
[0031] Furthermore, the thread-raising device 3 includes a transverse screw slide 31, one end of which is fixed to the slide of the first lifting screw slide 4. A thread-raising scraper 32 is installed at the lower slide of the transverse screw slide 31. The height of the thread-raising scraper 32 is adjusted by the first lifting screw slide 4, and the horizontal movement of the transverse screw slide 31 scrapes up the fluff on the surface of the fire grass end. This design makes the thread-raising process more automated and precise, improving the efficiency of fire grass fluff removal.
[0032] Furthermore, the first lifting screw slide 4, the second lifting screw slider 6, and the transverse screw slide 31 are all driven by motors. This design achieves automated control of the device, improves processing efficiency and accuracy, and reduces the labor intensity of manual operation.
[0033] Furthermore, several pressure rollers 51 are installed at the bottom of the lifting pressure plate 5, and the pressure rollers 51 are arranged at equal intervals. This design allows the lifting pressure plate 5 to distribute pressure more evenly when pressing the fire grass, avoiding deformation or damage to the fire grass due to excessive local pressure, and ensuring the integrity of the fire grass fibers and the peeling quality.
[0034] Furthermore, the lint scraper 32 is angled, with its bottom end close to the upper surface of the fire grass. This design makes it easy for the lint scraper 32 to be aligned and scrape up the fire grass fibers.
[0035] Furthermore, the pressure roller 51 is made of silicone material with elastic deformation properties. This design allows the pressure roller 51 to adapt to changes in the surface shape and thickness of the firewood when pressing it, while avoiding damage to the firewood or fluff due to excessive hardness, thus ensuring the quality of the firewood and the integrity of the fluff during the processing.
[0036] In use, the device for stripping fluff from fireweed is first placed on platform 1. Then, the lifting pressure plate 5 is lowered by the second lifting screw slider 6, so that the pressure roller 51 presses against the two sides of the fireweed, ensuring the stability of the fireweed during processing and preventing it from moving or shaking.
[0037] The top of platform 1 is equipped with a negative pressure air vent 11, which consists of several small holes, and the bottom is equipped with several negative pressure fans 12. When the negative pressure fans 12 are working, they generate suction through the negative pressure air vent 11, which firmly adheres the fire grass to platform 1, further enhancing the stability of the fire grass.
[0038] The thread-lifting device 3 is located at the upper part of the fire grass end and includes a transverse screw slide 31 and a thread-lifting scraper 32. One end of the transverse screw slide 31 is fixed to the slide of the first lifting screw slide 4 and is driven by a motor. The thread-lifting scraper 32 is height-adjusted by the first lifting screw slide 4 and moves horizontally by the transverse screw slide 31 to scrape up the fluff on the surface of the fire grass end. The thread-lifting scraper 32 is inclined, with its bottom end close to the upper surface of the fire grass, which allows for a smoother oblique cut at the root of the fluff, improving peeling efficiency and the integrity of the fluff.
[0039] The stripped fluffy yarn ends are manually placed on the twisting device 2 for twisting. The twisting device 2 includes an upper crossbar 21 and a lower crossbar 22, with the ends fixed to the housing of the first lifting screw slide 4. An upper roller 23 is rotatably mounted on the upper crossbar 21 via bearings, and a lower roller 24 is rotatably mounted on the lower crossbar 22 via bearings. A hand crank 25 is mounted on the upper roller 23, which drives the upper roller 23 to rotate. The upper roller 23 and the lower roller 24 clamp the fluffy yarn and perform the twisting operation.
[0040] The first lifting screw slide 4, the second lifting screw slide 6, and the transverse screw slide 31 are all driven by motors, realizing automated control of the device. This improves processing efficiency and accuracy while reducing the labor intensity of manual operation.
[0041] The pressure roller 51 is made of silicone material with elastic deformation properties. When pressing fire grass, the pressure roller 51 can adapt to changes in the surface shape and thickness of the fire grass, while avoiding damage to the fire grass or fluff due to excessive hardness.
