Description

Technical Field

[0001] This invention relates to the field of ramie processing technology, and more specifically, to a ramie collecting device. Background Technology

[0002] Ramie is one of my country's oldest natural fiber crops. Due to its high strength, excellent breathability, and natural antibacterial properties, ramie fiber is widely used in high-end clothing, mats, and medical supplies. After harvesting, ramie must undergo a stripping process to separate the ramie fibers from the stalks. Because the ramie stems and fibers are tightly adhered, during stripping, fragments of the stem often become embedded in the gaps between the fibers, resulting in a high impurity content in the collected ramie fiber and lowering its selling price. Simultaneously, these fragments can easily cause ramie fibers to entangle on rotating components such as rollers, affecting the integrity of the fibers and impacting the operation of ramie processing equipment, thus reducing production efficiency. Summary of the Invention

[0003] This invention provides a ramie collecting device that improves upon the problem of high impurity content in ramie fibers in existing technologies, thereby reducing the impurity content of ramie fibers.

[0004] To achieve the above objectives, the present invention provides a ramie collecting device, comprising:

[0005] A first ramie scraping mechanism includes a scraping roller and a pressure plate. The scraping roller is rotatably mounted. Multiple first scrapers are spaced circumferentially on the scraping roller, extending axially along the roller. The pressure plate is spaced radially from the scraping roller, and the gap between the pressure plate and the roller allows ramie fibers to pass through. When the first scrapers rotate to face the pressure plate, their direction of movement is the same as the direction of movement of the ramie fibers.

[0006] The second scraping mechanism includes two connected scraping wheels and a guide plate. The two scraping wheels are radially spaced apart and axially parallel to each other. Multiple second scrapers extending axially from the scraping wheels are circumferentially spaced on each scraping wheel. The second scrapers are spaced apart corresponding to the interval between adjacent second scrapers on the other scraping wheel. The two scraping wheels are axially parallel to the scraping pressure wheel. The gap between the two scraping wheels corresponds to the gap between the scraping pressure wheel and the pressure plate. The two scraping wheels are positioned on the side where the ramie fibers pass through the gap between the scraping pressure wheel and the pressure plate. When the first scraper rotates to face the pressure plate, it is on the side of the first scraper's moving direction. The rotation direction of the two scraping wheels on the opposite side is the same as the rotation direction of the scraping pressure wheel on the side facing the pressure plate, used to drive the ramie fibers to rotate in opposite directions. The guide plate partially surrounds one of the two scraping wheels and is radially spaced from the second scraper on it, corresponding to the side of the gap between the two scraping wheels away from the scraping pressure wheel.

[0007] The linear velocity of the outer edge of the first scraper away from the axis of the scraping roller is less than the linear velocity of the outer edge of the second scraper away from the axis of the scraping roller. The ramie collecting device of this invention is typically installed after a traditional ramie stripping device. After being processed by the ramie stripping device, the ramie stalks become ramie fibers with a higher impurity content and then enter the ramie collecting device. First, the ramie fibers, driven by the first scraper, pass through the gap between the scraping roller and the pressure plate, and enter between the two scrapers, where they are driven by the second scraper. Since the linear velocity of the first scraper is less than that of the second scraper, the moving speed of the ramie fibers driven by the second scraper is also greater than that of the first scraper. This causes relative slippage between the ramie fibers and the first scraper, allowing the first scraper to scrape and crush the ramie fibers, removing adhering ramie fibers and residual gum from the surface, and loosening or even separating the fiber bundles, thus promoting the growth of the ramie fibers. The ramie fibers are exposed by the exposed hemp fibers. Then, as the ramie fibers move through the gap between the two scraping wheels, they are bent several times by the second scraper on the two scraping wheels and scraped by the second scraper, causing some or all of the exposed hemp fibers to emerge from the ramie fibers and separate from them. Finally, as the ramie fibers enter the gap between the scraping wheels and the guide plate, a small amount of hemp fiber debris adhering to their surface is scraped away by the second scraper. Therefore, the ramie collecting device of the present invention can remove impurities from the ramie fibers produced by the stripping device at least three times, significantly reducing the impurity content of the ramie fibers.

[0008] As an optional technical solution, a ramie collection mechanism is also included. This mechanism comprises a first support rod and a second support rod, spaced apart from each other. The first and second support rods are positioned on the side of the guide plate away from the gap between the two scraper wheels. The first support rod is closer to the guide plate than the second support rod, which is rotatable axially. After passing through the gap between the scraper wheel and the guide plate, the ramie fiber emerges under the action of the second scraper. The head of the ramie fiber passes through the second support rod. Since the second support rod is rotatable, it guides the head of the ramie fiber to slide downwards, causing the middle of the fiber to rest on the second support rod. Simultaneously, it decelerates the ramie fiber, allowing the tail of the fiber to emerge and rest on the first support rod, thus facilitating the operator's collection of the processed ramie fiber.

[0009] As an optional technical solution, the second connecting pole includes a central shaft and a sleeve. The central shaft is spaced apart from the first connecting pole, and the sleeve is fitted onto the central shaft, with the sleeve rotatably connected to the central shaft. The central shaft and the sleeve are lightweight and do not require high precision in assembly and use, which helps to save costs.

[0010] As an optional technical solution, the ramie collecting device further includes a base plate disposed on the side of the second support rod opposite to the guide plate. The base plate is used to prevent the ends of the ramie fibers from moving. During the sliding of the ramie fibers along the second support rod, once the head of the ramie fiber abuts against the base plate, the base plate will prevent the ramie fiber from moving further, thereby controlling the length of the ramie fiber hanging from the second support rod, so that the operator can collect the ramie fiber.

[0011] As an optional technical solution, the first scraper is inclined along the rotation direction of the ramie scraping roller, and the angle between the line connecting one end of the first scraper to the other end along the axis of the ramie scraping roller and the radial direction of the ramie scraping roller is 15°-19°. The inclined arrangement of the first scraper can prevent the ramie fibers from tangling, which helps reduce the downtime of the ramie collecting device and improves production efficiency.

[0012] As an optional technical solution, the second scraper is inclined along the rotation direction of the scraper wheel, and the angle between the line connecting one end of the second scraper to the scraper wheel and the other end along the axis of the scraper wheel to the radial direction of the scraper wheel is 15°-19°. The inclined arrangement of the second scraper can prevent the ramie fibers from tangling, which helps to reduce the downtime of the ramie collection device and improve production efficiency.

[0013] As an optional technical solution, a feeding mechanism is also included. The feeding device includes a conveyor belt, which is positioned corresponding to the gap between the scraping roller and the pressure plate. The moving direction of the conveyor belt is the same as the linear velocity direction of the scraping roller towards the pressure plate. The starting end of the conveyor belt can be positioned corresponding to the discharge port of the ramie stripping device. After the ramie stalks are stripped, the ramie fibers can directly enter the ramie collecting device for further impurity removal, which helps improve production efficiency.

[0014] As an optional technical solution, the feeding device further includes two side guards, which are respectively disposed on both sides of the conveyor belt, with the ends of the two side guards facing away from the scraping roller gradually moving away from each other. The two side guards can guide the ramie fibers into the conveyor belt and prevent the ramie fibers from accumulating at the starting end of the conveyor belt.

[0015] As an optional technical solution, the ends of the two scraper wheels are respectively provided with gears, the two gears mesh, and the two gears have the same number of teeth.

[0016] As an optional technical solution, one of the two scraping wheels is connected to the hemp scraping pressure wheel via a transmission chain.

[0017] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0018] The ramie collecting device of the present invention, by setting a scraping roller and a pressure plate in the first scraping mechanism, and setting two scraping rollers and a guide plate that partially surrounds one of the scraping rollers in the second scraping mechanism, when processing ramie fibers, allows the ramie fibers to pass sequentially through the gap between the scraping roller and the pressure plate, the gap between the two scraping rollers, and the gap between the scraping roller and the guide plate, so that the first scraper set on the scraping roller and the second scraper set on the scraping roller can remove impurities from the ramie fibers multiple times, thereby reducing the impurity content of the ramie fibers.

[0033] Example 1

[0034] This embodiment provides a ramie collecting device, including:

[0035] The first ramie scraping mechanism includes a scraping roller 11 and a pressure plate 12. The scraping roller 11 is rotatably mounted. Multiple first scrapers 111 are spaced apart along the circumference of the scraping roller 11, and the first scrapers 111 extend axially along the scraping roller 11. The pressure plate 12 is spaced apart from the scraping roller 11 radially, and the gap between the pressure plate 12 and the scraping roller 11 is used for the passage of ramie fibers. When the first scrapers 111 rotate to the side facing the pressure plate 12, their moving direction is the same as the moving direction of the ramie fibers.

[0036] The second scraping mechanism includes two connected scraping wheels 21 and a guide plate 22. The two scraping wheels 21 are radially spaced apart and axially parallel to each other. Multiple second scraper blades 211 extending axially along the scraping wheel 21 are spaced apart circumferentially on the two scraping wheels 21. The second scraper blades 211 are spaced apart corresponding to the interval between adjacent second scraper blades 211 on the other scraping wheel 21. The two scraping wheels 21 are axially parallel to the scraping pressure roller 11, and the gap between the two scraping wheels 21 corresponds to the gap between the scraping pressure roller 11 and the pressure plate 12. When the first scraper 111, which is the side through which the ramie fiber passes through the gap between the scraping roller 11 and the pressure plate 12, rotates to the side facing the pressure plate 12, the rotation direction of the two scraper wheels 21 on the opposite side of the first scraper 111 is the same as the rotation direction of the scraping roller 11 on the side facing the pressure plate 12, and is used to rotate in opposite directions to drive the ramie fiber; the guide plate 22 is partially surrounded by one of the two scraper wheels 21 and is arranged radially spaced from the second scraper 211 on it, and is located on the side of the gap between the two scraper wheels 21 that is away from the scraping roller 11;

[0037] The linear velocity of the outer edge of the first scraper 111 away from the axis of the scraping roller 11 is less than the linear velocity of the outer edge of the second scraper 211 away from the axis of the scraping roller 21. The ramie collecting device of this invention is typically installed after a traditional ramie stripping device. After being processed by the ramie stripping device, the ramie stalks become ramie fibers with a higher impurity content and then enter the ramie collecting device. First, driven by the first scraper 111, the ramie fibers pass through the gap between the scraping roller 11 and the pressure plate 12, and enter between the two scrapers 21, where they are driven by the second scraper 211. Since the linear velocity of the first scraper 111 is less than that of the second scraper 211, the moving speed of the ramie fibers driven by the second scraper 211 is also greater than that of the first scraper 111. This causes relative slippage between the ramie fibers and the first scraper 111, allowing the first scraper 111 to scrape and crush the ramie fibers, removing adhering ramie fibers and residual gum from the surface of the fibers. It also loosens and even separates the fiber bundles of the ramie fibers, promoting the removal of loose fibers mixed within the ramie fibers. The ramie fibers are exposed; subsequently, in the gap between the two scraper wheels 21, the ramie fibers are bent several times and scraped by the second scraper 211 on the two scraper wheels 21 during the movement, so that part or all of the broken ramie fibers inside the ramie fibers are exposed from the inside of the ramie fibers and separated from the ramie fibers; finally, when the ramie fibers enter the gap between the scraper wheel 21 and the guide plate 22, a small amount of ramie fragments adhering to their surface, or ramie fragments that have not been completely separated from the inside of the ramie fibers, will be scraped away by the second scraper 211; it can be seen that the ramie collecting device of the present invention can remove impurities from the ramie fibers produced by the peeling device at least three times, which can greatly reduce the impurity content of the ramie fibers.

[0038] Optionally, the second scraper 211 provided on one of the two scraper wheels 21 extends into the gap between two adjacent second scraper blades 211 on the other scraper wheel 21. When the ramie fibers enter between the two scraper wheels 21, they will be bent by the second scraper blade 211 to a greater extent, which helps to improve the efficiency of removing ramie fibers.

[0039] Example 2

[0040] Based on Embodiment 1, a ramie collection mechanism is also included. This mechanism comprises a first support rod 31 and a second support rod 32, spaced apart. The first and second support rods 31 and 32 are positioned opposite the guide plate 22 to the gap between the two scraper wheels 21. The first support rod 31 is closer to the guide plate 22 than the second support rod 32, which is rotatably mounted axially. After passing through the gap between the scraper wheel 21 and the guide plate 22, the ramie fibers emerge under the action of the second scraper 211. The head of the ramie fiber passes through the second support rod 32. Since the second support rod 32 is rotatable, it guides the head of the ramie fiber downwards, causing the middle of the fiber to rest on the second support rod 32. Simultaneously, it decelerates the ramie fiber, allowing the tail of the fiber to emerge and rest on the first support rod 31, thus facilitating the operator's collection of the processed ramie fibers.

[0041] As an optional implementation, the second connecting rod 32 includes a central shaft 322 and a sleeve 321. The central shaft 322 is spaced apart from the first connecting rod 31, and the sleeve 321 is fitted onto the central shaft 322, with the sleeve 321 rotatably connected to the central shaft 322. The central shaft 322 and the sleeve 321 are lightweight, and the required precision for assembly and use is not high, which helps to save costs.

[0042] As an optional implementation, the ramie collecting device also includes a base plate disposed on the side of the second support rod 32 opposite to the guide plate 22. The base plate is used to prevent the ends of the ramie fibers from moving. As the ramie fibers slide along the second support rod 32, the head of the ramie fiber abuts against the base plate, preventing further movement of the ramie fiber. This controls the length of the ramie fiber hanging from the second support rod 32, allowing the operator to collect the ramie fiber.

[0043] As an optional implementation, the first scraper 111 is inclined along the rotation direction of the scraping roller 11, and the angle between the line connecting one end of the first scraper 111 to the other end along the axis of the scraping roller 11 outward and the radial direction of the scraping roller 11 is 15°-19°. The inclined arrangement of the first scraper 111 can prevent ramie fibers from tangling, which helps to reduce the downtime of the ramie collection device and improve production efficiency.

[0044] As an optional implementation, the second scraper 211 is inclined along the rotation direction of the scraper wheel 21, and the angle between the line connecting one end of the second scraper 211 to the other end along the axis of the scraper wheel 21 outward and the radial direction of the scraper wheel 21 is 15°-19°. The inclined arrangement of the second scraper 211 can prevent ramie fibers from tangling, which helps to reduce the downtime of the ramie collection device and improve production efficiency.

[0045] As an optional implementation, a feeding mechanism is also included. The feeding device includes a conveyor belt 41, which is positioned to correspond to the gap between the scraping roller 11 and the pressure plate 12. The moving direction of the conveyor belt 41 is the same as the linear velocity direction of the scraping roller 11 facing the pressure plate 12. The starting end of the conveyor belt 41 can be positioned to correspond to the discharge port of the ramie stripping device. After the ramie stalks are stripped, the ramie fibers can directly enter the ramie collecting device for further impurity removal, which helps to improve production efficiency.

[0046] As an optional implementation, the feeding device also includes two side guards 42, which are respectively disposed on both sides of the conveyor belt 41, with the ends of the two side guards 42 away from the scraping roller 11 gradually moving away from each other. The two side guards 42 can guide the ramie fibers into the conveyor belt 41 and prevent the ramie fibers from accumulating at the starting end of the conveyor belt 41.

[0047] As an optional implementation, the ends of the two scraper wheels 21 are respectively provided with gears, the two gears mesh, and the two gears have the same number of teeth.

[0048] As an optional implementation, one of the two scraping wheels 21 is connected to the hemp scraping pressure wheel 11 via a transmission chain.

[0049] Preferably, the scraping roller 11 and one of the scraping rollers 21 are simultaneously connected to the other scraping roller 21 via a transmission device, and the scraping roller 21 is connected to a driving component such as a motor.

[0052] S1: The ramie fibers that have undergone stripping and peeling are conveyed to conveyor belt 41;

[0053] S2: The transmission belt 41 conveys the ramie fibers to the gap between the scraping roller 11 and the pressure plate 12;

[0054] S3: The first scraper 111 and the pressure plate 12 remove impurities from the ramie fibers for the first time and transport the ramie fibers to the gap between the two scraper wheels 21;

[0055] S4: The second scraper 211 on the two scraper wheels 21 performs a second impurity removal on the ramie fibers and conveys the ramie fibers to the gap between the scraper wheel 21 and the guide plate 22;

[0056] S5: The second scraper 211 and the guide plate 22 perform a third impurity removal on the ramie fibers and transport the ramie fibers to the first support rod 31 and the second support rod 32, so that the ramie fibers are placed on the first support rod 31 and the second support rod 32.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the invention.
