Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a continuous integrated hemp stripping device. Background Technology

[0002] Ramie is primarily harvested for its bast fibers. Its stalks can be roughly divided into three parts from the inside out: the bast fiber, the fiber layer, and the husk. Ramie harvesting is a crucial step in the entire ramie industry. Due to the significant differences in ramie's inherent characteristics—uneven stalk thickness and height, long and flexible fibers, and a brittle, easily broken bast fiber—and the potential for blockages and jams in machinery, mechanization is extremely difficult. Current ramie harvesting methods require processing the bast fiber separately before processing the fiber layer and husk, resulting in low efficiency and high labor intensity. Utility Model Content

[0003] This invention provides a continuous integrated ramie stripping device to solve the problems of existing ramie harvesting devices, which have difficulty processing the ramie core, fiber layer and ramie shell at the same time, and the fact that broken ramie cores can easily cause blockage and jamming of mechanical devices.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A continuous integrated hemp stripping device includes a stripping frame and a hemp pressing device, a hemp folding device, a hemp scraping device, and a hemp pulling device installed on the stripping frame. The hemp pressing device, the hemp folding device, the hemp scraping device, and the hemp pulling device are connected by transmission and each includes two rollers rotating in opposite directions. The rollers are all hollow structures.

[0006] This invention uses a pressing device to break the outer layer of ramie, followed by a folding device to break the ramie bone into small segments. These segments pass through hollow rollers and fall to the bottom of the device for collection. Then, a scraping device removes the outer layer of ramie, while a pulling device holds and pulls the remaining fiber layer, sending it out for collection. This continuous, integrated processing of the ramie bone, fiber layer, and outer layer reduces intermediate transfer steps and labor costs. Furthermore, the hollow rollers prevent blockages or jamming of the machinery, extending the device's lifespan.

[0007] Furthermore, the pressing device includes a main pressing roller and a secondary pressing roller. Pressing roller bearings and meshing pressing roller gears are installed on the rotating shafts of the main pressing roller and the secondary pressing roller. The pressing roller bearings are fixedly installed on the peeling machine frame.

[0008] The main and auxiliary ramie rollers rotate in opposite directions through the meshing gears of the ramie rollers, squeezing and transmitting the ramie passing between them. This causes the ramie skin to break, exposing the inner core, which facilitates subsequent processing of the core.

[0009] Furthermore, both the main pressing roller and the auxiliary pressing roller include two pressing roller discs and a number of pressing roller teeth arranged at equal intervals, with the two ends of the pressing roller teeth respectively fixedly installed on the two pressing roller discs.

[0010] By evenly fixing the pressing roller teeth between two pressing roller discs, the main pressing roller and the auxiliary pressing roller form a hollow structure. This allows the outer skin and hemp segments falling from the ramie to pass through the inside of the main and auxiliary pressing rollers and fall downwards to the bottom of the device, preventing them from entering the transmission mechanism or structural gaps of the mechanical device and causing damage. At the same time, the pressing roller teeth on the main and auxiliary pressing rollers can squeeze the passing ramie, making it easier to break the outer skin of the ramie and expose the internal hemp.

[0011] Furthermore, the folding device includes a main folding roller and a secondary folding roller. Folding roller bearings and meshing folding roller gears are installed on the rotating shafts of the main folding roller and the secondary folding roller. The folding roller bearings are fixedly installed on the peeling machine frame.

[0012] The ramie stalks are received by the main and auxiliary folding rollers, which are fed by the main and auxiliary pressing rollers. Because the angles at which the main and auxiliary folding rollers hold the ramie stalks are different from those at the main and auxiliary pressing rollers, the ramie stalks are bent at a large angle, causing the hemp fibers to break. Simultaneously, since the main and auxiliary pressing rollers have already broken the ramie outer layer, the broken hemp fibers can fall out through the gaps between the broken outer layers, thus completing the separation of the ramie outer layer and the hemp fibers.

[0013] Furthermore, both the main folding roller and the auxiliary folding roller include two folding roller discs and a number of folding roller teeth arranged at equal intervals, with the two ends of the folding roller teeth respectively fixedly installed on the two folding roller discs.

[0014] By evenly fixing the teeth of the ramie folding roller between two folding roller discs, the main and auxiliary folding rollers form a hollow structure. This allows the outer skin and hemp segments falling from the ramie to pass through the interior of the main and auxiliary folding rollers and fall downwards to the bottom of the device, preventing them from entering the transmission mechanism or structural gaps and causing damage. At the same time, the main and auxiliary folding rollers can also compress the passing ramie, creating traction and compression forces. While pulling the ramie to move, they can also squeeze broken ramie fibers out of the ramie outer skin, accelerating the separation efficiency of ramie fibers and hemp segments.

[0015] Furthermore, the hemp scraping device includes a main hemp scraping roller and an auxiliary hemp scraping roller. Hemp scraping roller bearings and meshing hemp scraping roller gears are installed on the rotating shafts of the main hemp scraping roller and the auxiliary hemp scraping roller. The hemp scraping roller bearings are fixedly installed on the peeling machine frame.

[0016] The ramie husks are received by the main scraping roller and the auxiliary scraping roller, which are fed by the main folding roller and the auxiliary folding roller. At the same time, the main scraping roller and the auxiliary scraping roller, which have a faster rotation speed, pull the ramie fibrous material away and scrape off the ramie husks, leaving the ramie fibers and pulling them to move.

[0017] Furthermore, both the main scraping roller and the auxiliary scraping roller include two scraping roller discs and a number of equally spaced scraping roller teeth. The two ends of the scraping roller teeth are respectively fixedly installed on the two scraping roller discs. The end of the scraping roller teeth away from the rotation axis of the main scraping roller or the rotation axis of the auxiliary scraping roller is provided with a cutting edge. The scraping roller teeth on the main scraping roller and the scraping roller teeth on the auxiliary scraping roller are meshed with each other.

[0018] By evenly fixing the scraping roller teeth between two scraping roller discs, the main scraping roller and the auxiliary scraping roller form a hollow structure. This allows the outer skin and hemp segments falling from the ramie to pass through the inside of the main and auxiliary scraping rollers and fall downwards to the bottom of the device, preventing them from entering the transmission mechanism or structural gaps of the mechanical device and causing damage. At the same time, the blades on the scraping roller teeth continuously scrape the surface of the ramie fibers as they rotate, removing as much of the surface hemp shell as possible and reducing rework.

[0019] Furthermore, the hemp-pulling device includes a main hemp-pulling roller and an auxiliary hemp-pulling roller. Hemp-pulling roller bearings and meshing hemp-pulling roller gears are installed on the rotating shafts of the main hemp-pulling roller and the auxiliary hemp-pulling roller. The hemp-pulling roller bearings are fixedly installed on the peeling machine frame.

[0020] The ramie fibers fed by the main scraping roller and the auxiliary scraping roller are received by the main scraping roller and the auxiliary scraping roller, and the ramie fibers are clamped and pulled so that the ramie fibers can continuously pass through the main scraping roller and the auxiliary scraping roller at a certain speed.

[0021] Furthermore, both the main hemp-pulling roller and the auxiliary hemp-pulling roller include two hemp-pulling roller discs and a number of hemp-pulling roller teeth arranged at equal intervals, with the two ends of the hemp-pulling roller teeth respectively fixedly installed on the two hemp-pulling roller discs.

[0022] By evenly fixing the teeth of the ramie pulling roller between the two ramie pulling roller discs, the main ramie pulling roller and the auxiliary ramie pulling roller form a hollow structure. This allows the outer skin falling from the ramie to pass through the inside of the main ramie pulling roller and the auxiliary ramie pulling roller and fall downwards to the bottom of the device. This prevents the outer skin or ramie segments from entering the transmission mechanism, structural gaps, or other parts of the mechanical device and causing damage to the device.

[0023] Furthermore, it also includes a drive motor, and the output shaft of the drive motor, the pressing device, the folding device, the scraping device, and the pulling device are connected by a chain drive.

[0024] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0025] (1) This utility model uses a pressing device to crush the ramie skin, and then a folding device to break the ramie bone into small segments. The broken ramie bone segments pass through the hollow roller and fall to the bottom of the device for collection. Then, the ramie skin is scraped off by the scraping device with a faster rotation speed. The remaining fiber layer is clamped and pulled by the pulling device and sent out of the stripping device for subsequent collection. This realizes the continuous integrated processing of ramie bone, fiber layer and ramie shell, reducing the intermediate transfer process in the ramie processing process and the manpower consumption. At the same time, the ramie bone and the ramie shell that fall during the processing fall through the hollow roller, preventing them from blocking or jamming the mechanical device and extending the service life of the device.

[0026] (2) Through the transmission between the meshing gears of the ramie pressing rollers, the main ramie pressing roller and the auxiliary ramie pressing roller rotate in opposite directions, squeezing and transmitting the ramie passing between the main ramie pressing roller and the auxiliary ramie pressing roller, causing the ramie epidermis to break and exposing the internal hemp bone, which facilitates the subsequent processing of the hemp bone.

[0027] (3) By uniformly fixing the pressing roller teeth between the two pressing roller discs, the main pressing roller and the auxiliary pressing roller form a hollow structure, so that the epidermis and hemp segments falling from the ramie pass through the inside of the main pressing roller and the auxiliary pressing roller and fall down to the bottom of the device, avoiding the epidermis or hemp segments from entering the transmission mechanism, structural gaps, etc. of the mechanical device and causing damage to the device; at the same time, the pressing roller teeth on the main pressing roller and the auxiliary pressing roller can squeeze the passing ramie, making it easy to crush the epidermis of the ramie and expose the internal hemp;

[0028] (4) The ramie stalks fed by the main pressure roller and the auxiliary pressure roller are received by the main folding roller and the auxiliary folding roller. At the same time, since the angle at which the main folding roller and the auxiliary folding roller hold the ramie is different from the angle at which the main pressure roller and the auxiliary pressure roller hold the ramie, the ramie stalks are bent at a large angle, causing the hemp core to break. Meanwhile, since the main pressure roller and the auxiliary pressure roller have already broken the ramie skin, the broken hemp core can fall out from the gap between the broken skin, thus completing the separation of the ramie skin and the hemp core.

[0029] (5) By uniformly fixing the ramie folding roller teeth between the two ramie folding roller discs, the main ramie folding roller and the auxiliary ramie folding roller form a hollow structure, so that the epidermis and hemp segments falling from the ramie pass through the inside of the main ramie folding roller and the auxiliary ramie folding roller and fall downwards to the bottom of the device, avoiding the epidermis or hemp segments from entering the transmission mechanism, structural gaps, etc. of the mechanical device and causing damage to the device; at the same time, the main ramie folding roller and the auxiliary ramie folding roller can also form a certain amount of compression on the passing ramie, forming traction force and a certain amount of compression force, while pulling the ramie to move, it can also squeeze the broken ramie out of the ramie epidermis, accelerating the separation efficiency of ramie fiber and hemp.

[0060] Example 2

[0061] Based on Example 1, when the device performs the ramie stripping operation, the ramie stalks are fed in through the meshing opening of the main pressing roller 201 and the auxiliary pressing roller 202. The flattened ramie stalks enter between the main folding roller 301 and the auxiliary folding roller 302 at a linear velocity v1 of the main pressing roller 201 and the auxiliary folding roller 202. They are rapidly bent by the instantaneous impact of the high-speed rotating folding rollers. The hard and brittle ramie core is broken and flies out at a linear velocity v2 similar to that of the main folding roller 301 and the auxiliary folding roller 302. The ramie fibers, due to their good flexibility, remain unbroken and continue to move slowly towards the subsequent device, thus achieving the separation of the ramie core and the ramie fibers.

[0062] In a more preferred embodiment, a unit length of stem is taken as the research object, and its mass is determined by the hemp bark. and hemp bone Composition. When the ramie stalk collides instantaneously with the roller teeth, the impulse equation of the ramie stalk is established based on the momentum theorem;

[0063] The momentum possessed by the stem before the collision:

[0064] ;

[0065] The momentum of the stem after the collision:

[0066] ;

[0067] According to the principle of impulse during a collision:

[0068] ;

[0069] Right now:

[0070] ;

[0071] in: The peeling force of a single folding roller tooth on the stalk; The duration of a single impact;

[0072] Assuming the rotational speed of the folding roller is... The number of impacts of the folding roller teeth on the stalk per unit time is ,but

[0073] ;

[0074] in: This refers to the number of teeth on the hemp-peeling roller.

[0075] It is also known that the speed at which the ramie stalks enter the ramie folding roller is... ,but

[0076] ;

[0077] in: The diameter of the hemp pressing roller; The rotational speed of the hemp pressing roller;

[0078] This allows us to determine the number of impacts per unit length of the stem.

[0079] ;

[0080] Because the time it takes for the hemp folding roller teeth to rotate one revolution is Assuming the single impact time of the hemp roller teeth on the hemp bone...

[0081] ;

[0082] Because the impact force of each impact on the ramie stalk by the folding roller is approximately equal, the impulse received per unit length of stalk is:

[0083] ;

[0084]

[0085] Therefore, the peeling force of a single folding roller tooth on the stalk is:

[0086]

[0087] The kinetic analysis of the ramie stalk separation process shows that during the collision between the ramie folding roller and the stalk, the impulse of the roller teeth is converted into the momentum of the ramie bone, giving the ramie bone the separation force. Thus, the stalk separation effect is related to factors such as the roller tooth rotation speed and roller tooth diameter, while the tooth diameter characterizes the meshing clearance between the roller teeth. At the same time, it is known from the actual situation that the number of roller teeth also has a significant impact on the separation effect.

[0088] In a more preferred embodiment, assuming the inner diameter of the pressing roller is 130mm and the outer diameter is 140mm, the inner diameter of the folding roller is 150mm and the outer diameter is 160mm, the inner diameter of the scraping roller is 200mm and the outer diameter is 260mm, and the inner diameter of the pulling roller is 240mm and the outer diameter is 300mm, after testing, the optimal rotation speed of the pressing roller and the folding roller is 85-90RPM, and the optimal rotation speed of the peeling roller and the pulling roller is 420-460RPM.

[0089] The linear velocity of the hemp pressing roller is obtained as follows:

[0090] ;

[0091] ;

[0092] It can be seen that the linear velocity of the hemp pressing roller is 0.57-0.61 m / s;

[0093] Linear velocity of the folding roller:

[0094] ;

[0095] ;

[0096] It can be seen that the linear velocity of the folding roller is 0.67-0.7 m / s;

[0097] Linear velocity of the scraping roller:

[0098] ;

[0099] ;

[0100] It can be determined that the linear velocity of the hemp scraping roller is 4.4-4.81 m / s;

[0101] Linear velocity of the hemp-pulling roller:

[0102] ;

[0103] ;

[0104] It can be known that the linear velocity of the hemp roller is 6.15-7.14 m / s.
