Description

Technical Field

[0001] This invention relates to the field of mechanical processing technology for specialty economic crops, specifically to a ramie stripping machine, and more particularly to a ramie stripping machine with a repositioning clamp. Background Technology

[0002] Ramie is a specialty of my country, commonly known internationally as "Chinese grass." Its planting area and yield account for over 90% of the world's total, giving it a strong competitive advantage in the international market. However, ramie is a perennial bast fiber crop, typically harvested three times a year, and must be processed manually or mechanically to obtain coarse fiber. Surveys indicate that harvesting alone accounts for more than three-fifths of the labor required in the entire ramie production process. Furthermore, the harvesting season is highly seasonal, labor-intensive, and technically demanding, making it a critical link in ramie raw material production and a significant factor restricting the large-scale, industrialized development of ramie production in my country.

[0003] Since 1959, my country has been researching simple ramie scrapers, which began to be widely used in production in the late 1960s. By squeezing and bending ramie, the ramie fibers are broken and the outer shell is destroyed, ultimately separating the fibers from the fibers. This method is 2 to 3 times more efficient than manual scraping. At the same time, research on ramie stripping machines was also carried out in China, and more than 30 kinds of ramie stripping machines were developed. After 1980, ramie stripping machines began to be used in production. By using stripping rollers to break the ramie fibers, the fibers are separated. Ramie stripping machines are about 5 to 10 times more efficient than simple scrapers.

[0004] Ramie scraping machines are an improvement on manual ramie scraping tools, but they do not deviate from the principle of manual scraping. The efficiency is generally 1~2kg / h, and each person can only scrape about 15kg of raw ramie per day. The efficiency is low and cannot meet the scraping and processing requirements of large-scale ramie planting.

[0005] Although more than 30 models of ramie stripping machines have been developed, the main models currently used in production are single-roller and double-roller reverse-pull ramie stripping machines, totaling 5 to 6 models. Their structures are similar, and their working principles are the same. Their ramie stripping efficiency is greatly related to the operator's skill level. The general efficiency is 10 to 15 kg / h, and one ramie stripping machine requires 3 people to operate.

[0006] The above-mentioned ramie stripping machine requires operators to manually feed the ramie, and after one end is stripped, it is manually pulled back. Then, the stripping direction is manually changed, and the ramie is fed in and stripped again. This is time-consuming and labor-intensive, and the back-pulling force is large, so it has not been truly promoted and applied.

[0007] Therefore, providing a ramie stripping method that requires less manual operation and can completely solve the problem of manual back-pulling / feeding, as well as a ramie stripping machine back-pulling deboning actuator for implementing the method, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the existing defects and provide a ramie stripping and hulling machine with a shifting clamp, thereby solving the above-mentioned problems.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a ramie stripping and mortar-scraping machine with a shifting clamp, characterized in that it mainly includes a material preparation device, a shifting clamping device, a feeding / reverse pulling device, and a ramie stripping and mortar-scraping device.

[0010] Furthermore, the material preparation device mainly consists of a material preparation trough, an upper alignment baffle, a material preparation device frame, and a lower alignment baffle.

[0011] Furthermore, the shifting clamping device mainly consists of a first clamping mechanism, a second clamping mechanism, a lateral moving mechanism, a flipping mechanism, and an auxiliary support mechanism.

[0012] Furthermore, the ramie stripping device mainly consists of a stripping roller, a transmission mechanism, and a frame housing.

[0013] Furthermore, the shifting clamping device is provided with a first clamping mechanism and a second clamping mechanism. Both the first clamping mechanism and the second clamping mechanism are composed of an upper clamping plate, a lower clamping plate, a clamping plate track, a transmission device, and a spring. The difference is that the positioning grooves of the upper and lower clamping plates of the first clamping device are suitable for clamping columnar objects, i.e., unpeeled ramie stalks; the positioning grooves of the upper and lower clamping plates of the second clamping device are suitable for clamping strip-shaped objects, i.e., peeled ramie fibers.

[0014] Furthermore, the clamping plate track is located at both ends of the upper and lower clamping plates, with tracks on both the left and right sides of the clamping plates, making the clamping more stable; the lower clamping plate is fixed to the lower clamping plate track by bolts, the upper clamping plate is sleeved on the clamping plate track, and a spring is sleeved between the upper and lower clamping plates. The function of the spring is that when the transmission device stops working, the upper clamping plate can return to its initial state under the action of elastic potential energy, which facilitates subsequent continuous clamping operations.

[0015] Furthermore, the aforementioned positioning and clamping device is equipped with a lateral moving mechanism, which consists of a lateral moving track, a lateral moving frame, a spring, a first clamping mechanism, and a second clamping mechanism. The lateral moving track is fixed to the lateral moving frame by bolts. The ends of the first clamping mechanism and the second clamping mechanism are both sleeved on a symmetrically distributed lateral moving track. A spring is sleeved on the lateral moving track between the first clamping mechanism and the second clamping mechanism. The function of the spring is that, under the action of external force, the first clamping mechanism and the second clamping mechanism have a range of lateral sliding due to the elastic deformation of the spring.

[0016] Furthermore, the shifting clamping device is equipped with a flipping mechanism, which consists of a flipping power unit, a drive shaft, a support shaft, a bearing housing, a coupling, and a flange. The pair of flanges are bolted to the middle of both ends of the transverse moving mechanism. The drive shaft and the support shaft are sleeved on the flange axis, and the bearing housing is sleeved on the drive shaft and the support shaft axis. The flipping power unit is connected to the drive shaft through a coupling. The same bearing housing is bolted to the slider of the feeding / reverse pulling device.

[0017] Furthermore, the repositioning clamping device is provided with an auxiliary support mechanism; the auxiliary support mechanism consists of an upper stop rod, a lower stop rod, an upper stop rod rail, a lower stop rod guide rail, and a spring. The upper stop rod guide rail is bolted to the upper clamping plate of the first clamping mechanism; the lower stop rod rail is bolted to the lower clamping plate of the first clamping mechanism; the upper stop rod is sleeved on the upper stop rod guide rail, and the lower stop rod is sleeved on the lower stop rod guide rail; the spring is sleeved in the gap between the stop rod and the guide rail. The characteristic of this auxiliary support mechanism is that it can assist the first clamping mechanism in clamping the ramie stalk, preventing the ramie stalk from losing external support after being crushed by the first clamping device.

[0018] Furthermore, the material preparation device is equipped with a material preparation trough, which is connected to the bracket of the feeding / reverse pulling device. The installation height is 30cm, the internal height of the material preparation trough is 4cm, and the length is 200cm, which can store two rows of ramie stalks.

[0019] Furthermore, the upper alignment baffle is hinged to the bottom of the material preparation trough, and the lower alignment baffle is parallel to the upper alignment baffle and mounted on the bottom of the guide rail bracket, with a distance of 110cm between the upper and lower alignment baffles. This ensures that the shifting clamping device can clamp the middle part of the ramie stalk, thereby ensuring the separate peeling of the head and tip of the ramie stalk. The function of the upper and lower alignment baffles is that, under gravity, the ramie stalks in the material preparation trough can adaptively adjust their head alignment, thereby ensuring that the heads of the ramie stalks entering the peeling device are flush, thus ensuring the peeling quality of the ramie.

[0020] Furthermore, the feeding area of ​​the material preparation device, the clamping center line of the upper and lower clamping plates of the shifting clamping device, the upper plane of the linear guide rail of the feeding / reverse pulling device, and the center position of the peeling area of ​​the ramie peeling device are all located on the same horizontal line.

[0021] Furthermore, the guide rail areas on both sides of the feeding / reverse pulling device are arranged from the center line of the material preparation area of ​​the material preparation device to the center axis of the ramie stripping roller of the ramie stripping device.

[0022] Furthermore, the feeding port of the ramie stripping device is provided with a limiting block, and the same limiting block can restrict the first clamping mechanism and the second clamping mechanism of the shifting clamping device from entering the stripping area.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: This type of ramie stripping machine with repositioning clamping can clamp ramie stalks of most diameters through the repositioning clamping device, and provides sufficient clamping force for subsequent stripping of ramie stalks. The clamped ramie stalks are fed into the stripping rollers by the conveying action of the feeding / reverse pulling device. Under the swirling action of a pair of meshing and rotating stripping rollers, the ramie fibers in the ramie stalks are broken off and fall off. The broken ramie fibers fall into the discharge port and are discharged. The feeding / reverse pulling mechanism withdraws from the stripping area, the repositioning clamping device repositions, and moves the unstripped ramie stalk tip to the side closer to the stripping area. The feeding / reverse pulling device feeds it in again, and then it is pulled out of the stripping area to obtain complete and clean ramie fibers. This method of alternating clamping and peeling ramie can remove the core of the ramie stalk and the outer layer of the ramie fibers, greatly improving efficiency and reducing the risk of hand injury and labor costs compared to the original double-roller manual reverse-pulling peeling method.

[0048] The invention will now be further described with reference to the accompanying drawings.

[0049] Example 1: Please refer to Figure 1-20 A ramie stripping and hulling machine with a repositioning clamping mechanism, characterized in that it mainly includes a material preparation device 1, a repositioning clamping device 2, a feeding / reverse pulling device 3, and a ramie stripping and hulling device 4 (such as...). Figure 1 As shown), the material preparation device 1 mainly consists of a material preparation trough 11, an upper alignment baffle 12, a material preparation device frame 13, and a lower alignment baffle 14. The shifting clamping device 2 mainly consists of a first clamping mechanism 21, a second clamping mechanism 22, a lateral moving mechanism 23, a flipping mechanism 24, and an auxiliary support mechanism 25 (as shown). Figure 2As shown), the first clamping mechanism 21 consists of a first clamping bearing seat 211, a first clamping cam motor 212, a first clamping crankshaft 213, a first clamping toothed clamping plate 214, a spring 215, a spring sleeve 216, and a clamping plate slide groove 217; the second clamping mechanism consists of a second clamping bearing seat 221, a second clamping cam motor 222, a second clamping crankshaft 223, a second clamping toothed clamping plate 224, a spring 225, a spring sleeve 226, and a clamping plate slide groove 227; the lateral movement mechanism 23 consists of a lateral movement slide groove 231, a lateral movement spring 232, and a lateral movement slide rod 233; the flipping mechanism 24 consists of a flipping power motor 241, a coupling 242, a bearing seat 243, and a flange 244; the auxiliary support mechanism 25 consists of an auxiliary support slide groove 251, a spring 252, and an auxiliary support clamping plate 253 (as shown). Figure 8 As shown, the pressure applied by the first and second clamping mechanisms is not limited to using cams or crankshafts; it can also use screws, cylinders, or other mechanisms, which will not be elaborated here. The feeding / reverse pulling device 3 mainly consists of a spur gear 301, a feeding / reverse pulling drive motor 310, a motor connecting plate 311, a rack 312, a linear guide rail 313, and a guide rail bracket 314. The feeding / reverse pulling device 3 is not limited to using gear and rack linear transmission; it can also be implemented using a wheel and rope structure or a screw and guide rail linear module, which will not be elaborated here. The ramie stripping device mainly consists of a stripping roller, a transmission mechanism, and a frame housing, as described in Embodiment 1. The ramie stripping device uses a double-roller stripping mechanism, but a single-roller stripping mechanism can also be used; the principle is the same, and will not be elaborated here. The stripping roller consists of a stripping plate 408 and a stripping roller 409. The transmission mechanism consists of a bearing seat 412, a transmission gear 411, a driven shaft 421, a drive shaft 420, a large pulley 413, a small pulley 417, a stripping power motor 416, and a belt 415. The machine frame consists of a stripping frame 410, a discharge port 414, an upper baffle 439 for the feeding port, a lower baffle 442 for the feeding port, a feeding port stop bar 441, a left guide rail 440, and a right guide rail 443 (e.g., ...). Figure 9 , Figure 10 (As shown); the large pulley 413 and the small pulley 417 are connected by a belt 415; the hemp beating board 408 is bolted to the circumference of the hemp beating roller 409.

[0050] The plan layout diagram of each device in Embodiment 1 is shown below. Figure 3 Taking the direction from the feeding area to the stripping area as the positive direction, the horizontal guide rail of the feeding / reverse pulling device 3 is parallel to the positive direction and intersects at the midline between the feeding area and the stripping area; the shifting clamping device 2 is arranged at the midpoint of the horizontal guide rail of the feeding / reverse pulling device 3, referred to as the origin in the picture. For the specific stripping process in Example 1, see Figure 4 Throughout the peeling process, the clamping states of the first and second clamping mechanisms are shown in the following figures. Figure 6The first stage: the first clamping mechanism clamps the tip of the ramie; the second stage: after the ramie inside the dotted frame, i.e. the ramie head, is stripped, the second clamping mechanism will move out of the stripping area under the limiting action of the stop bar; the third stage: after the position is changed, the second clamping mechanism clamps the ramie head, the first clamping mechanism moves out of the stripping area, and the tip is stripped.

[0051] To facilitate ramie feeding, the shifting clamping device 2 is equipped with a flipping power motor 241, which is at the same tilt angle as the material preparation trough 11 when feeding (e.g., ...). Figure 13 As shown), it facilitates the clamping of ramie stalks 668 and can also be used for clamping and repositioning ramie; when the head is stripped, the flipping motor 241 rotates 180° counterclockwise, and the repositioning clamping device 2 flips accordingly, thereby exchanging the head and tip of the ramie, realizing repositioning stripping (as shown). Figure 18 As shown), it can also be used to adjust the angle during ramie stripping and reverse pulling. The shifting clamping device rotates to the optimal angle for pulling out, which makes it easier to peel off the ramie bone fragments in the ramie stalk diameter, resulting in better stripping quality and higher cleanliness.

[0052] To ensure the quality of stripping the ramie in the middle, the shifting clamping device 2 is equipped with a lateral moving mechanism 23. The first clamping mechanism 21 and the second clamping mechanism 22 are sleeved on the lateral sliding rod 233 in the lateral moving mechanism 23. The lateral spring 232 is sleeved on the lateral sliding rod 233 between the first clamping mechanism 21 and the second clamping mechanism 22 (e.g., Figure 5 As shown), the function of the transverse spring 232 is to provide a certain elastic deformation range for the clamping mechanism located on the outside to approach the ramie stripping device 4 when the ramie is being stripped, thus solving the problem that the ramie in the middle part of the clamping device cannot be stripped (as shown). Figure 16 (As shown); the transverse spring 232 further functions to provide elastic force when the ramie is stripped and pulled back, preventing the feeding / pull mechanism 3 from applying too much force and causing the ramie fibers to break.

[0053] To ensure the clamping force of the shifting clamping device 2, the shifting clamping device 2 is provided with a first clamping mechanism 21 and a second clamping mechanism 22. Both have the same clamping principle. The clamping principle of the first clamping mechanism is described here: the first clamping cam motor 212 starts, driving the first clamping crankshaft 213 connected to it to rotate. The first clamping crankshaft 213 contacts the first clamping toothed clamping plate 214. As the first clamping cam motor rotates, the contact depth between the first clamping crankshaft 213 and the first clamping toothed clamping plate 214 increases, thereby achieving the clamping function (e.g., ...). Figure 15 (As shown); the difference between the first and second clamps lies in the positioning grooves on the clamping plates. The first clamp holds a cylindrical object, so its appearance is longitudinally toothed (as shown). Figure 8As shown), its function is to prevent the ramie stalk from sliding left and right and from detaching from the clamp. The second clamp is a strip-shaped object (such as...). Figure 8 As shown), the appearance is transversely toothed, and the surface material is rubber, which increases the clamping area, improves the static friction coefficient, provides greater friction, and prevents the ramie fibers from detaching from the clamp (as shown). Figure 17 (As shown).

[0054] To ensure the successful feeding / pulling and pull-back of the ramie stalks, such as... Figure 16 , Figure 19 As shown, the feeding / reverse pulling device 3 and the horizontal line of the middle part of the ramie stripping drum are on the same horizontal plane; the shifting clamping device 2 is installed on the same guide rail 440 of the feeding / reverse pulling device 3; this ensures that the first clamping mechanism, the second clamping mechanism, and the auxiliary support clamping plate 253 can be limited by the feed port stop bar 441, thereby ensuring that the ramie can enter the meshing part of the ramie stripping drum horizontally when it is fed / reverse pulled; the ramie stripping device 4 is provided with a left guide rail 440 and a right guide rail 443, and the left guide rail is the same The right guide rail and the guide rail of the feeding / reverse pulling device 3 are located on the same horizontal and equal-height surface, thereby ensuring that the feeding / reverse pulling device and the same shifting clamping device can have a deeper stripping length with the stripping roller, thus ensuring that the ramie stalks in the middle part held by the same shifting clamping device can be stripped by the stripping roller; the ramie waste material detached after the ramie stalks are stripped will be discharged through the discharge port 414. The upper baffle 439 of the feeding port and the lower baffle 442 of the feeding port can prevent the ramie waste material from splashing and ensure the safety of stripping.

[0055] To ensure that the shifting clamping device can automatically clamp the ramie at the material preparation device, the material preparation device 1 is equipped with a material preparation trough 11. The same material preparation trough is connected to the guide rail bracket 314 of the feeding / reverse pulling mechanism 3. The angle between the material preparation trough and the guide rail bracket is 45°, the installation height is 30cm, the internal height of the same material preparation trough is 4cm, and the length is 200cm, which can store two rows of ramie stalks (e.g., Figure 12 As shown), the upper alignment baffle 12 is hinged to the bottom of the material preparation trough, and the lower alignment baffle 14 is installed parallel to the upper alignment baffle at the bottom of the guide rail bracket 314. The distance between the upper and lower alignment baffles is 110cm, thereby ensuring that the shifting clamping device 2 can clamp the middle part of the ramie stalk 668 (as shown). Figure 14 As shown), this ensures the phased stripping of the ramie stalk head and tip (as shown). Figure 16 , Figure 19 As shown), the function of the upper and lower alignment baffles is to enable the ramie stalks in the material preparation trough 11, which is located at a 45° inclination angle under gravity, to adaptively adjust their head alignment (e.g., ...). Figure 14 As shown in the figure, this ensures that the ramie stalks entering the stripping device 4 are flush, thereby ensuring the stripping quality of the ramie.

[0056] To ensure lateral transmission, the lateral transmission of the feed / reverse pull device 3 is achieved through a feed / reverse pull drive motor 310 in conjunction with a spur gear 301 and a rack 312. The feed / reverse pull drive motor and the spur gear are connected by a key, the feed / reverse pull drive motor and the motor connecting plate 311 are connected by bolts, and the same motor connecting plate and the linear guide rail 313 are connected by bolts, thus forming a parallel relationship between the feed / reverse pull drive motor and the linear guide rail (e.g., ...). Figure 11 (As shown).

[0057] To ensure the rotational power of the dual rollers, the stripping roller is fixedly connected to the transmission mechanism. The stripping motor 416 is connected to the small pulley 417 via a key, and the small pulley is connected to the large pulley 413 via a belt 415. The same large pulley and the transmission gear 411 are fixed to the drive shaft 420 via a key. The same transmission gear has a transmission ratio of 1:1 and meshes in the same direction. The other transmission gear 411 is connected to the driven shaft 421 via a key. The pair of stripping rollers are respectively connected to the same drive shaft and driven shaft, meshing in the same direction (e.g., ...). Figure 9 As shown in the diagram), by utilizing the strength differences in the structure of ramie stalks, when the stalks are fed into the feeding hopper and enter the rotating ramie stripping drum, the stalks are bent, and the shear displacement generated by the shear stress causes the phloem and hemp bone to separate, and the epidermis and fiber layer to separate, thus carrying out the ramie stripping work.

[0058] Example 2: Please refer to Figure 21 , Figure 22 The only difference between Example 2 and Example 1 is the following structure; the rest of the structure is the same. Example 2 differs from Example 1 in that it has two peeling zones, namely peeling zone 1 and peeling zone 2. The mechanical structure of the peeling zone in Example 2 is the same as that in Example 1. Taking the direction from peeling zone 1 to peeling zone 2 as the positive direction, the feeding zone is installed in the middle of the two peeling zones, and the installation angle is perpendicular to the horizontal guide rail of the feeding / reverse pulling device 3. The specific peeling process of Example 2 is shown in [link to example]. Figure 22 .

[0059] Compared with the prior art, the beneficial effects of this invention are as follows: This type of ramie stalk stripping machine, through the repositioning clamping device, can clamp ramie stalks of most diameters and provide sufficient clamping force for subsequent stripping. The clamped ramie stalks are fed into the stripping drum by the conveying action of the feeding / reverse pulling device. Under the rotation of a pair of meshing rotating stripping drums, the hemp fiber portion in the ramie stalk is broken off from the fiber and falls off. The broken hemp fiber fragments fall into the discharge port and are discharged. The feeding / reverse pulling mechanism withdraws from the stripping area, the repositioning clamping device repositions, and moves the unstripped ramie stalk tip to the side closer to the stripping area. The feeding / reverse pulling device feeds it in again, and then it is pulled out of the stripping area, resulting in complete and clean ramie fibers (such as...). Figure 20 (As shown). This method of rotating clamping and peeling ramie can completely remove the hemp core and the outer layer of ramie fibers within the ramie stalk diameter. Compared with the original double-roller manual reverse-pulling peeling method, it greatly improves efficiency and reduces the risk of hand injury from the rollers and manual labor.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
