Description

Technical Field

[0001] The invention relates to the technical field of hemp peeling machinery, and more specifically to a hemp bast fiber non-crushed stem wet peeling whole bone separator and a separation process for obtaining hemp bast fiber crops. Background Art

[0002] In recent years, with the further increase of China's cotton gap and the increasing depletion of chemical resources such as petroleum, hemp bast fiber crops have become increasingly important in China's textile raw materials. However, the stripping and processing of hemp bast fiber is labor-intensive, seasonal, inefficient, has a large waste rate, a poor working environment, and high harvesting costs. In addition, the shortage of labor and the increasing price have limited the market prospects for the expansion of the production scale of various hemp fibers. Therefore, efficient automation of hemp stripping machinery has always been pursued by people.

[0003] Hemp bast fibers (soft fibers) include: ramie, flax, jute, kenaf, hemp, industrial hemp, fennel, nettle, ramie and kenaf, as well as willow bark, mulberry bark, cotton stalk bark, etc. The fibers obtained from hemp bast fiber crops after degumming are a natural textile raw material, which is widely used in clothing, carpets, handbags, shoes and hats, bedding, socks, ropes, packaging materials and other fields. However, hemp bast fibers are closely connected with hemp bones, and the bast and hemp bones need to be separated by manual or mechanical methods. Regarding the separation method, various hemp bast fiber crops are divided into wet stripping and dry stripping according to the original habits. At present, the wet stripping and separation methods of hemp bast fibers such as ramie, jute, kenaf, industrial hemp, mulberry bark, willow bark, etc. in my country are still mainly manual. Although various research institutes, enterprises and individual agricultural machinery households have carried out research on wet stripping processing machinery, the wet stripping machines currently developed in my country all use methods such as squeezing and scraping the stems of fiber crops to achieve the separation of the skin and bones of hemp bast fibers. However, the squeezing and scraping methods have problems such as large fiber loss, reduced fiber strength, and high labor intensity of operation; industrial hemp, flax, and ramie are harvested and lignified, and then rained and dewed, and the fiber is produced by the existing device of crushing the stems, rubbing, and vibrating the screen to drop the broken bones. The operating environment of the workers is very poor, the broken bones are not completely dropped, the fiber is damaged, and the short fiber rate is high; and because the degree of rain and dew is not ideal, the skin and bones are more adhered, and the impurity rate is high.

[0004] Hemp bast fibers generally have the properties of moisture absorption and breathability, anti-static, heat resistance, UV protection, antibacterial, and sound insulation. They have become a world-recognized high-quality natural textile fiber raw material. After the hemp bast fiber stems are harvested, they need to go through the "stripping" process to obtain industrially usable fibers from the stems. The stems of hemp bast fiber crops can be roughly divided into epidermis, phloem and xylem from the outside to the inside. The usable fibers are located in the phloem, and the phloem and xylem and phloem fibers are closely connected. It is very difficult to remove the gum in the stem bones and phloem of the crop stems to obtain clean industrial fibers. It is time-consuming, labor-intensive and energy-intensive. The "difficulty in stripping hemp" has become a bottleneck restricting the development of the industrial hemp industry.

[0005] Regardless of whether the current stripping methods for various hemp bast fiber crops use wet stripping or dry stripping, it is impossible to avoid the drawbacks of incomplete stripping, low efficiency, high loss, high impurity content, affecting the subsequent degumming effect and serious degumming pollution. Especially for apocynum, since the current industry promotion is mainly in Xinjiang, apocynum originally grew mainly in the wild in the protected area, and fresh branches were not allowed to be harvested. They had to wait until they dried up after the New Year to be harvested. However, the dry weather and water shortage in Xinjiang cannot achieve natural rain and dew, so they can only use dry stems to crush and vibrate to produce short fibers with limited length and high impurity content, resulting in the apocynum industry being unable to be promoted. Now apocynum has begun to promote artificial cultivation. The rhizomes of apocynum have a strong ability to sprout. If fresh stems are used for harvesting, they can be harvested twice a year, and the fiber utilization rate of fresh stems will be higher.

[0006] Therefore, in order to solve the shortcomings existing in the current market, it is necessary to propose a non-stem crushing method, wet stripping, stem whole bone branch peeling continuous automatic separation equipment to solve the above-mentioned problems. Summary of the invention

[0042] Example:

[0043] like Figure 1-Figure 3As shown, a hemp bast fiber non-crushed stem wet-stripping bone separation machine of the present invention comprises a pre-processing frame 1 located at the front side and a separation main frame 2 connected to the rear end of the pre-processing frame 1; a pre-processing unit is installed on the pre-processing frame 1; a first group of transfer rollers 7, a first pair of stripping devices 8, a second group of transfer rollers 9, a second pair of stripping devices 10, a third group of transfer rollers 11, and a bone output support plate 12 are installed on the upper bracket of the separation main frame 2 from front to back. A bast fiber conveying device 14 and a gathering and discharging slide plate 13 are also included below the separation main frame 2.

[0044] The pre-treatment unit is used to feed the bast crops that need to be peeled in a complete, constant speed, continuous and straight manner, and send the bast crops to the first group of transfer rollers 7. The stripping device is used to process and strip the bast fibers from the stems of hemp bast fiber crops in sections. There are three groups of transfer rollers in total, which are used to transfer the pre-treatment unit feeding to the stripping device and to continue to transfer the crop stems peeled by the first pair of stripping devices 8 to the second pair of stripping devices 10 for peeling again, and then to the bone-setting output pallet 12 to send out the peeled stems and bone-setting branches. The bast fiber conveying device 14 is used to slide the bast fibers peeled by the two pairs of stripping devices onto the corresponding conveyor belt through the two-side gathering discharge slides 13, and transmit the bast fibers horizontally to the side of the separation main frame 2 to output the bast fibers.

[0045] Specifically, Figure 4 As shown, the pretreatment unit includes a pretreatment unit conveyor belt 3, a gathering bucket 4, and a feeding roller. The pretreatment unit conveyor belt 3 and the corresponding conveying motor are installed on the pretreatment frame 1, and the conveying motor drives the pretreatment unit conveyor belt 3 to transport the bast crops from front to back; the gathering bucket 4 is installed above the pretreatment frame 1 near the rear side, and it is located above the pretreatment unit conveyor belt 3, and is used to limit the bast crops that need to be peeled; the feeding roller is installed at the rearmost end above the pretreatment frame 1, and includes an elastic roller 5 and a first transmission shaft 6, and the elastic roller 5 and the first transmission shaft 6 are both connected through both ends. The fixed bearing seat is installed on the pretreatment frame 1, the elastic roller body of the elastic roller 5 is parallel to the first transmission shaft 6 and is arranged closely up and down, and the pretreatment unit conveyor belt 3 passes between the elastic roller body and the first transmission shaft 6; the two ends of the elastic roller 5 are rotatably installed on the elastic roller mounting plates on both sides of the pretreatment frame 1 through corresponding first bearings, and a first vertical movable groove is opened on the elastic roller mounting plate, the first bearing is arranged in the corresponding first vertical movable groove, and the top end of the first bearing is connected to the groove top of the first vertical movable groove through a spring 24; the first transmission shaft 6 is transmission-connected to the first power mechanism 15.

[0046] In the present application, the first bearings at both ends of the elastic roller 5 generate passive transmission by two sets of springs 24 to control the tightness and strength of crop feeding; a pre-treatment unit conveyor belt 3 passes between the elastic roller body and the first transmission shaft 6, and cooperates with the gathering bucket 4 to control the flattening of the crop, keeping the branches of the hemp bast fiber crops intact, at a constant speed, and continuously straightly laid for feeding.

[0047] During operation, the roots of the bast crops that need to be peeled are continuously laid forward on the pretreatment unit conveyor belt 3, conveyed to the gathering bucket 4, and fed to the feed roller for transfer and conveying after limiting sorting. The feed roller includes an elastic roller 5 and a first transmission shaft 6. The bearings at both ends of the elastic roller 5 are passively driven by two groups of springs 24, so that the crop stems are clamped on the pretreatment unit conveyor belt 3 through the elastic roller body and the first transmission shaft 6, and at the same time, the crop stems are conveyed synchronously with the three groups of transfer rollers on the separation main frame 2 through gears and chains according to the speed ratio.

[0048] The first group of transfer rollers 7 is arranged at the rear end of the feed rollers on the pretreatment unit and the front end of the first pair of stripping devices 8; the second group of transfer rollers 9 is arranged between the first pair of stripping devices 8 and the second pair of stripping devices 10; the third group of transfer rollers 11 is arranged at the rear end of the second pair of stripping devices 10 and the front end of the bone adjustment output tray 12.

[0049] The first group of transfer rollers 7 transports the bast crops to the first pair of stripping devices 8 in an orderly manner. The first pair of stripping devices 8 peel the bast crops up and down and then supply them to the second group of transfer rollers 9 for further transport. The second group of transfer rollers 9 transports the bast crops to the second pair of stripping devices 10. After peeling the bast crops up and down again, they are supplied to the third group of transfer rollers 11 for further transport. The third group of transfer rollers 11 transports the peeled stems and branches to the output pallet 12 for ejection.

[0050] Further, such as Figure 6As shown, the first group of transfer rollers 7, the second group of transfer rollers 9, and the third group of transfer rollers 11 have the same structure, and all of them include a slotted elastic roller 17 and a second transmission shaft 18. The slotted elastic roller 17 and the second transmission shaft 18 are both mounted on the separation main frame 2 through fixed bearing seats at both ends. The slotted roller body of the slotted elastic roller 17 is parallel to the second transmission shaft 18 and is arranged adjacent to each other up and down. The tail end of the pre-processing unit conveyor belt 3 is aligned between the slotted roller body and the second transmission shaft 18; the two ends of the slotted elastic roller 17 are connected by corresponding second bearings. The transfer roller mounting plates are rotatably mounted on both sides of the separation main frame 2, and a second vertical movable groove is opened on the transfer roller mounting plates. The second bearing is arranged in the corresponding second vertical movable groove, and the top end of the second bearing is connected to the groove top of the second vertical movable groove through a spring 24; the first group of transfer rollers 7, the second group of transfer rollers 9, and the third group of transfer rollers 11 are respectively connected to the first power mechanism 15 fixed on the separation main frame 2 in transmission connection, specifically, the second transmission shafts 18 in the three groups of transfer rollers are respectively connected to the first power mechanism 15 in transmission connection.

[0051] In the present invention, the bearings at both ends of the slotted elastic roller 17 generate passive transmission and compression force by two sets of springs 24, so as to control the clamping, travel speed and separation effect of the crop stems during the peeling process and transfer.

[0052] The main body of the slotted roller on the transfer roller is made of silicone material. The main body of the slotted roller is customized with slots to avoid crushing the stem bones of hemp bast fiber crops during peeling, further improving the clamping, travel speed and separation effect of the crop stems during the peeling process. A more specific explanation is that the crop stems are transferred and transported through the clamping of the slotted elastic roller 17 and the second transmission shaft 18. The slotted elastic roller 17 is a passive transmission, which will generate appropriate clamping force and friction, and will not form a strong crushing on the crop stems, resulting in stem breakage and bone fragmentation.

[0053] In the present invention, the gear at one end of the first transmission shaft 6 is connected to a power mechanism (i.e., the first power mechanism 15) through a chain and the gear at one end of the second transmission shaft 18 at the lower end of the three groups of transfer rollers on the separation main frame 2, and is synchronously transmitted according to the speed ratio.

[0054] like Figure 5As shown, the first pair of stripping devices 8 includes a first upper stripping device and a first lower stripping device which are parallel to each other and arranged diagonally, and the second pair of stripping devices 10 includes a second upper stripping device and a second lower stripping device which are parallel to each other and arranged diagonally; the first upper stripping device, the first lower stripping device, the second lower stripping device, and the second upper stripping device are installed in the middle of the separation main frame 2 in an inverted eight-shaped shape as a whole; a bast fiber conveying device 14 is installed as a whole below the two pairs of stripping devices, and the bast fiber conveying device 14 is installed on the lower bracket of the separation main frame 2. Gathering and discharging slide plates 13 are installed on both sides of the upper conveying belt corresponding to the bast fiber conveying device 14. The bast fibers stripped by the two pairs of stripping devices are gathered and collected by the gathering and discharging slide plates 13 on both sides to the corresponding conveying belt of the bast fiber conveying device 14, and are transported out from the side of the separation main frame 2 in a path perpendicular to the bast crop peeling and conveying direction. Each corresponding stripping device in the two pairs of stripping devices is respectively connected to the second power mechanism 16 fixed on the separation main frame 2 in a transmission manner.

[0055] like Figure 7 , Figure 8 As shown, the corresponding single stripping devices in the two pairs of stripping devices each include a central shaft 19, a fixed disk 20, a flange sleeve 23, a water drop ring mounting shaft 21, and a water drop ring movable beater 22. Three fixed disks 20 are sleeved and fixed on the central shaft 19, and the fixed disks 20 are fixed on the central shaft 19 through the flange sleeve 23. The outer peripheral edges of the three fixed disks 20 are uniformly provided with mounting holes as a whole, and the mounting holes are correspondingly sleeved with water drop ring mounting shafts 21. The number of water drop ring mounting shafts 21 is generally six to ten, and specifically eight in this embodiment; The top and bottom ends of the drip ring mounting shaft 21 are respectively fixedly connected to the fixed disks 20 at both ends of the central shaft 19; the drip ring mounting shaft 21 is evenly penetrated with the water drop annular movable beaters 22; both ends of the central shaft 19 are rotatably mounted on the separation main frame 2 through bearings, the central shaft 19 is transmission-connected to the second power mechanism 16, and the upper stripping device and the lower stripping device in the same pair of stripping devices rotate synchronously in opposite directions, so that the water drop annular movable beaters 22 hung on the eight water drop ring mounting shafts 21 fixed by the fixed disk 20 will be staggered when rotating.

[0056] Further, such as Fig. 9 , Fig.10 , Fig.11 As shown, the water drop ring movable beater 22 is made of spring steel with good toughness, not easy to rust, not easy to deform, and wear-resistant, and is composed of a spring ring 26 for passing through the shaft and a water drop shaped ring body 27 for stripping; the spring ring 26 for passing through the shaft is formed by coiling, and one side is coiled to one and a half circles, and the other side is coiled to half a circle; the water drop ring movable beaters 22 on two adjacent water drop ring mounting shafts 21 in a single stripping device are threaded in opposite directions.

[0057] Due to the unique curvature and center of gravity of the water drop ring movable beater 22 and the way of producing angles by sequentially passing through the eight water drop ring mounting shafts 21 in forward and reverse directions, a set of upper and lower stripping devices can more effectively produce interlaced stripping when rotating to strip the outer bast fibers of the stems of hemp bast fiber crops.

[0058] Further explanation is: the spring ring 26 of the present invention that passes through the shaft is coiled, one side is coiled one and a half circles, and the other side is coiled half a circle. By reasonably utilizing the different numbers of coiling circles, the first water drop ring mounting shaft 21 is controlled to be neatly passed through in the same direction, and the second water drop ring mounting shaft 21 is passed through the ring in the opposite direction of the first one. In this way, eight water drop ring mounting shafts 21 are passed through in sequence. In this way, the upper stripping device and the lower stripping device of a pair of stripping devices can produce an interlaced collision of about 20° during the forward and reverse rotations. Since the water drop ring beater is in the shape of a water drop and the center of gravity deviates from the rotation and swinging, the bast on the surface of the stem can be effectively scraped and peeled, but the stem branches will not be damaged, and the peeled wood fragments are prevented from being mixed in the fiber bast.

[0059] The crop stems are clamped by the transfer rollers and pass through the upper and lower stripping devices in forward and reverse rotation. The bast fibers on the surface of the crop stems are segmented and stripped off to appropriate lengths by utilizing the grid spacing and angles between the eight water droplet annular movable beaters on each stripping device and the rotating speed of the stripping device.

[0060] At the same time, the first upper stripping device, the first lower stripping device, the second upper stripping device, and the second lower stripping device are all installed on the separation main frame 2 through the fixed bearing seats at both ends of the corresponding central axis 19, and the fixed bearing seats at both ends of the central axis 19 of the two upper stripping devices can be adjusted in the up and down and left and right directions on the corresponding stripping device mounting plate to adjust the spacing between the upper and lower stripping devices.

[0061] In a further specific embodiment, the preprocessing frame 1 is connected to the front end of the separation main frame 2 through a quick-connect connector, and the front end of the preprocessing frame 1 is equipped with a complete machine control cabinet and a speed regulator for adjusting the corresponding speeds of the first power mechanism 15 and the second power mechanism 16. The first power mechanism 15 and the second power mechanism 16 can be adjusted through the speed regulator according to the length, thickness, and peeling convenience of the branches of various hemp bast fiber crops to meet the peeling needs of different crops.

[0062] When in use, if the crop stem passes through the transfer roller at a fast speed and the stripping device rotates slowly, the longest possible phloem can be separated. However, if the stripping device rotates too slowly, the phloem cannot be effectively scraped. If it rotates too fast, the centrifugal force is too large and the stem bones are not flexible, so it is necessary to adjust the speed of the power motors in the first power mechanism 15 and the second power mechanism 16 according to different hemp crops.

[0063] A further explanation is that during the peeling process of different crop stems, the inventors have found through repeated tests and simulation experiments that the rotation speed of the two pairs of upper and lower stripping devices during peeling and the offset spacing of the upper and lower stripping devices will affect the peeling effect of different hemp bast fiber crops (different stem thickness, stem freshness, and lignification). If the rotation speed is too low, the bast cannot be separated well, and if the speed is too high, the stems, branches and bast fibers of the crop will be damaged; a large offset spacing of the upper and lower stripping devices is suitable for crops with thicker stems, and a small offset spacing is suitable for crops with thinner stems. Therefore, the embodiment of the present invention designs two pairs of upper and lower stripping devices, and the gears at one end of the central axis 19 are synchronously driven by the same power mechanism (i.e., the second power mechanism 16) through a chain, and the required different rotation speeds are adjusted by the speed regulator; the fixed bearing seats at both ends of the central axis 19 of the two upper stripping devices can adjust the spacing up and down.

[0064] In a further specific embodiment, Figure 3 As shown, in order to enable hemp bast fiber crops to be peeled continuously and not to be disturbed by the branches and trunks when the peeling device rotates to peel and cause the machine to jam, guide plates 25 are correspondingly provided between the first group of transfer rollers 7 and the first pair of peeling devices 8, between the first pair of peeling devices 8 and the second group of transfer rollers 9, between the second group of transfer rollers 9 and the second pair of peeling devices 10, and between the second pair of peeling devices 10 and the third group of transfer rollers 11. In order to ensure smooth transfer and transportation of crop stems in the middle, the output ends of the two pairs of upper and lower peeling devices in the separation and peeling process have inertial throwing lines for the crop stems, and guide plates 25 are installed at the output ends according to different throwing lines, which can smoothly guide the transfer rollers for transportation.

[0065] In the embodiment of the present invention, two pairs of upper and lower stripping devices are arranged in an inverted eight-shaped arrangement. By stripping the branches of hemp bast fiber crops twice, it can be effectively ensured that the bast on the crop stems is stripped clean. Finally, the stems and branches that have not been crushed or flattened are thrown out through the bone-forming output tray 12, thereby achieving the stripping of the crop stems, and the peeled complete stems and branches can be used as by-products for subsequent development of wicker products.

[0066] However, for some special crops, such as industrial hemp, the stems are hollow and semi-woody, and the rotation speed of the stripping device used to peel the industrial hemp cannot be too fast. If only the existing two pairs of stripping devices are set, the stripping will not be clean, so it is necessary to add a stripping device to increase the number of stripping devices to three or four pairs. The added stripping device can increase the speed accordingly to strip the remaining bast. At the same time, since the length of the bast stripped here will be shorter, the bast fiber conveying device 14 below and the corresponding gathering and discharging slide plate 13 need to be configured separately to distinguish it from the longer bast stripped in front.

[0067] Specifically, the upper bracket of the separation main frame 2 is equipped with a first group of transfer rollers 7, a first pair of stripping devices 8, a second group of transfer rollers 9, a second pair of stripping devices 10, a third group of transfer rollers 11, a third pair of stripping devices, a fourth group of transfer rollers, and a bone setting output support plate 12 in sequence from front to back, wherein the first pair of stripping devices 8 and the second pair of stripping devices 10 are installed in an inverted figure eight shape as a whole, and the second pair of stripping devices 10 and the third pair of stripping devices are installed in a regular figure eight shape as a whole.

[0068] Alternatively, the upper bracket of the separation main frame 2 is equipped with a first group of transfer rollers 7, a first pair of stripping devices 8, a second group of transfer rollers 9, a second pair of stripping devices 10, a third group of transfer rollers 11, a third pair of stripping devices, a fourth group of transfer rollers, a fourth pair of stripping devices, a fifth group of transfer rollers, and a bone setting output support plate 12 in sequence from front to back, wherein the first pair of stripping devices 8 and the second pair of stripping devices 10 are installed in an inverted figure eight shape as a whole, the second pair of stripping devices 10 and the third pair of stripping devices are installed in a regular figure eight shape as a whole, and the third pair of stripping devices and the fourth pair of stripping devices are installed in an inverted figure eight shape as a whole.

[0069] In a specific embodiment of the present invention, the first power mechanism 15 and the second power mechanism 16 both control the first transmission shaft 6 on the corresponding feed roller, the second transmission shaft 18 on the transfer roller and the center shaft 19 on the two pairs of peeling devices by chain drive. However, in addition to chain drive, belt drive can also be used, and the transmission method is not limited.

[0070] In a specific embodiment of the present invention, both sides and the top of the installation frame composed of the pre-processing frame 1 and the separation main frame 2 are provided with box plates, and the bottom of the installation frame is also provided with walking wheels to facilitate the walking movement of the entire mechanism.

[0071] according to Figure 3 As shown by the dotted line in the figure, the hemp bast fiber non-crushed stem wet stripping and bone separation machine of the present invention has a pre-treatment unit that continuously lays out the bast crops that need to be stripped and feeds them in an orderly manner. The first group of transfer rollers 7 transports the input crop stems to the first pair of stripping devices 8 in an orderly manner. The first pair of stripping devices 8 strip the input crop stems up and down and supply them to the second group of transfer rollers 9 for continuous transport, and then transport them to the second pair of stripping devices 10 for stripping up and down again, and then transport them to the bone output support plate 12 through the third group of transfer rollers 11 to throw out the stripped stems and bone branches. The bast fibers completely stripped by the two pairs of stripping devices slide freely through the two sides of the bottom gathering discharge slide plates 13 to the conveyor belt corresponding to the bast fiber conveying device 14, and the bast fibers are output to the side of the separation main frame 2 in an orderly manner. During the stripping operation, each device operates automatically and cooperates with the stripping to efficiently complete the bast stripping of the input crop stems - removing the stems and bones - collecting bast fibers.

[0072] The bast fiber obtained by the hemp bast fiber non-stem-crushing wet-stripping whole-bone separator of the present application does not contain woody broken bones of crop stems, thereby solving the technical problem of high bone content in various hemp fibers stripped by existing hemp stripping machines.

[0073] Ramie, flax, jute, kenaf, green hemp, industrial hemp, fennel, nettle, ramie, kenaf as well as willow bark, mulberry bark, cotton stalk bark, these plants belong to woody plants, including trees and shrubs. Due to different wood structures and hardness, the operation methods for separating phloem from woody trunks are also different. The wood structure of shrubs is brittle, while the wood structure of trees is compact and elastic. The non-stem-crushing wet-stripping whole bone separator of the present invention uses the water drop annular movable beater 22 on the stripping device to hit a material with a hardness greater than the hardness of the phloem under the action of the rotation speed. The water drop annular movable beater 22 will cause rebound and no longer generate striking force. According to the different wood structures, thickness, length, degree of adhesion between phloem fiber and trunk and required fiber length, the water drop annular movable beater 22 separates the phloem from the trunk in a way that the center of gravity is externally supported and the force is controllable.

[0074] Take ramie as an example of shrubs: the wood structure is brittle, and the bast fibers are tightly held together with the trunk. According to the requirements for the length of the bast, the speed regulator can be operated to adjust the feed speed to control fast feed, and the thickness is less than 5 cm. The impact strength of the teardrop-shaped movable beater is based on the quality of the ramie to only peel the skin without damaging the trunk. The speed of the stripping device is adjusted to a suitable medium speed on the speed regulator.

[0075] Take mulberry bark as an example: the wood structure is compact and elastic, the bast is thick and the fiber is tightly attached to the trunk. The speed regulator can be operated to adjust the feeding speed and control the fast feeding. The thickness is less than 10cm. The striking force of the teardrop-shaped movable beater is based on the quality of the mulberry bark. The speed of the stripping device is adjusted to a suitable medium or high speed on the speed regulator.

[0076] Adjust the spacing of the upper and lower water drop ring movable beaters of the first pair of stripping devices and the spacing of the upper and lower water drop ring movable beaters of the second pair of stripping devices respectively. Spacing requirement: When the upper and lower water drop ring movable beaters rotate centrifugally, the two adjacent rings must not touch each other, and the spacing is 2-3mm. Because each pair of stripping devices is arranged diagonally, the mulberry bark moves parallel to the upper and lower water drop ring movable beaters at a spacing of 2-3mm. When the water drop ring beaters rotate, they penetrate the moving mulberry bark without colliding with each other and at different angles to complete the bast stripping.

[0077] The present invention also provides a hemp bast fiber non-crushed stem wet-stripping whole bone separation process, using the hemp bast fiber non-crushed stem wet-stripping whole bone separation machine, comprising the following steps:

[0078] S1. Automatically and continuously feed crop stems;

[0079] S2. The bast of the crop stems is scraped and peeled, and the bast on the surface of the crop stems is automatically separated twice to obtain bast fibers;

[0080] S3. Completely peel off the entire crop stems and branches to develop willow products.

[0081] Specifically, the present invention uses the water droplet annular movable beater of the stripping device to form an arc surface contact with each gravity contact point of the bast on the stem surface. Under the premise of not damaging the fibers and stem branches, the bast on the stem surface can be scraped and peeled, thereby avoiding the peeled woody debris from being mixed in the fiber bast, and achieving the scraping and peeling of the bast of the crop stems; the slotted elastic roller of the transfer roller is used to avoid strong crushing of the crop stems, avoiding stem breakage and bone fragmentation, and ensuring smooth transfer of the crop stems through appropriate clamping and friction; and automatically obtaining bast fibers for textile use.

[0082] The beneficial effects of the hemp bast fiber stripping process of the present invention include:

[0083] To strip ramie fiber, existing ramie stripping machines all adopt the method of crushing ramie stalks, separating the crushed ramie stalks, and obtaining the ramie bast layer to obtain the whole long ramie fiber, but the subsequent degumming of the ramie long fiber requires hanging cage and beating process; for ramie biological degumming, the long fiber will affect the uneven biological degumming, and in actual spinning applications, the ramie long fiber must be combed and shortened before use, all of which increase the difficulty of degumming and affect the final ramie fiber utilization rate. However, the hemp bast fiber stripping process of the present invention can directly obtain bast short fibers that do not contain ramie stalk fragments, can meet the length requirements of ramie spinning fibers, contain less impurities, and reduce the labor of stripping, which is more conducive to the uniform biological degumming process of ramie fibers, large degumming loading capacity, and degumming of higher quality ramie textile fibers.

[0084] To strip the apocynum fiber, the existing apocynum fiber is made of lignified dry branches. The existing stem crusher and the roller of the stem crushing mechanism of the vibrating screen squeeze the lignified stem stalk core into small wood chips. Only apocynum short fibers containing a large amount of small wood chips can be produced, which has large losses, poor operating environment, extremely low fiber utilization rate, and great difficulty in subsequent degumming of apocynum. "Apocynum is short in length, poor in spinnability, easy to scatter during textile processing, and low in production rate" has always been the industry consensus on apocynum, resulting in the lack of mass production and effective utilization of apocynum fiber industry. However, the hemp bast fiber stripping process of the present invention can directly use fresh branches harvested twice a year to wet-peel the hemp skin, obtain bast short fibers that do not contain broken bones of ramie stems, and have a low impurity content. The stripped ramie bast can reach 6-12 cm, which reduces the workload of repeatedly removing impurities from the original raw materials before degumming, and can simply and quickly obtain fibers, making it convenient for subsequent degumming to produce ramie fibers with curly fine fibers with higher added value, which can greatly improve the spinnability of ramie, enable the rapid and large-scale promotion of ramie planting, and expand industrial development.

[0085] Stripping industrial hemp fiber, the existing industrial hemp fiber is harvested through the natural rain and dew on the ground, using the existing stem crusher, vibrating screen stem crushing mechanism roller to squeeze the lignified stem core into small wood chips to separate the industrial hemp long hemp wet spinning process; when beating the long hemp, the industrial hemp second coarse short fiber containing a large amount of wood chips is separated, and then repeatedly removed and degummed to produce industrial hemp short fiber and blended with other fibers.

[0086] The hemp bast fiber stripping process of the present application can directly wet-strip the hemp bark from fresh branches of industrial hemp plants after collecting flowers, seeds and leaves, so as to obtain short bast fibers without industrial hemp stem fragments and with low impurity content. The stripped industrial hemp bast can reach 15-25cm, and can be effectively degummed to obtain hemp textile fibers suitable for dry spinning process.
