Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ramie machines, specifically an integrated ramie peeling and degumming machine. Background Technology
[0002] Ramie has been used as a textile raw material in my country for nearly 5,000 years, with a long history of cultivation. Before the 1980s, ramie stripping and harvesting were done entirely by hand or with simple scrapers, which was labor-intensive. Since the 1990s, small-scale ramie stripping devices have been developed domestically, solving the needs of some individual farmers for ramie stripping and processing. According to statistics, labor for ramie stripping and harvesting accounts for more than 50% of the total labor in ramie production, and the cost of ramie stripping and harvesting accounts for about 50% of the price of raw ramie (coarse fiber). Therefore, the development of ramie stripping and harvesting machines is of great significance.
[0003] Chinese utility model patent with announcement number CN204918853U discloses a belt-type automatic sisal peeling machine, which processes the root and tail of sisal leaves separately during the conveying process. It has a high degree of automation, high efficiency, and low investment. The processed sisal fibers are cleaner and neater, making it especially suitable for small and medium-sized sisal processing enterprises. However, it can only peel sisal leaves or coarse sisal fibers with bark, and cannot straighten a certain amount of coarse sisal fibers with bark. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides an integrated ramie dehulling and degumming machine, which is equipped with a separation device at the outlet of the crushing chamber. The separation device can separate a certain amount of coarse ramie fibers with bark after dehulling, making it easier for operators to perform subsequent operations on the coarse ramie fibers with bark after dehulling.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The integrated ramie dehulling and degumming machine is equipped with a drying chamber, a crushing chamber, and a separation component connected in sequence along the raw material movement direction. The separation component includes a second conveyor belt, a protective shell, a first threaded rod, and a separation device. The second conveyor belt is connected to the output port of the crushing chamber. The bottom of the connecting frame is located at the input end of the second conveyor belt, and the top of the connecting frame is rotatably engaged with the protective shell. A first motor is fixed inside the protective shell. One end of the first threaded rod is fixed to the output shaft of the first motor, and the other end of the first threaded rod is rotatably engaged with the inner wall of the protective shell. A first slotted hole is opened at the bottom of the protective shell, and the top of the separation device passes through the first slotted hole and is threadedly engaged with the first threaded rod.
[0007] Furthermore, the bottom of the drying chamber is connected to the input port of the compaction chamber via the first conveyor belt.
[0008] Furthermore, the crushing chamber includes a first outer shell, inside which a first crushing wheel and a second crushing wheel, as well as a traction wheel for assisting the movement of raw materials, are arranged in parallel; the surfaces of the first crushing wheel and the second crushing wheel are provided with spiral protrusions in different directions; and a waste outlet is provided at the bottom of the first outer shell.
[0009] Furthermore, at least one fan is provided at the top of the inner cavity of the first housing.
[0010] Furthermore, a high-temperature spray gun is installed at the output port of the compaction chamber.
[0011] Furthermore, the separating device includes a threaded sleeve that is threaded to the outer wall of the first threaded rod, one end of the connecting rod is fixed to the threaded sleeve, and the other end of the connecting rod is fixed to the top of the fixed frame after passing through the first strip hole. Multiple separating rods are fixed at the bottom of the fixed frame, and the bottom of the separating rods is clearance-fitted with the surface of the second conveyor belt.
[0012] Furthermore, a sorting chamber is provided between the drying chamber and the compaction chamber. The sorting chamber includes a second outer shell. A second motor is fixed in the middle of the inner cavity of the second outer shell. The output shaft of the second motor is fixed to one end of a second threaded rod. The other end of the second threaded rod spirally passes through the middle of the mounting plate and is rotatably connected to the inner wall of the second outer shell. Guide rods are symmetrically fixed on both sides of the mounting plate. Both ends of the guide rods are fixed to the inside of the second outer shell. Multiple cylinders are fixed on the top of the mounting plate. The bottom of the cylinders passes through the mounting plate and is fixed to the pressing plate. A layer of soft rubber is provided at the bottom of the pressing plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model is equipped with a separation device at the outlet of the crushing chamber, which can separate the coarse hemp fibers after stripping.
[0015] 2. The drying chamber serves as the initial processing unit, and its interior is equipped with uniformly distributed heat source devices to perform preliminary drying of the raw materials through hot air circulation.
[0016] 3. The input port of the crushing chamber receives the dried raw material through the first conveyor belt, forming a continuous connection from the first stage of processing to the middle stage. The crushing chamber squeezes and crushes the coarse hemp fiber with bark to achieve the effect of "hemp beating". The coarse hemp fiber with bark after beating is input into the separation device.
[0017] 4. In the initial state, the separating device is close to one end of the crushing chamber. During use, the separating device reciprocates on the surface of the threaded rod, and the speed of the separating device is different from the speed of the second conveyor belt. The separating device can then separate the coarse hemp fibers output from the crushing chamber into multiple relatively independent coarse hemp fibers.
[0018] 5. The first and second pressing rollers compress the flax fibers with bark in different directions, resulting in a better compression effect. The width of the flax fibers with bark is customized according to production needs and the size of the equipment. When the flax fibers with bark are laid flat, the ends overlap to ensure a roughly uniform thickness. Because the fiber thickness and length differ between the beginning and end of the flax fibers with bark, the dried and hardened flax fibers need to be compressed to change their shape. Due to the difference in flexibility between the dried cortex and the fiber, the fibers of the flax fibers with bark do not separate from the cortex after compression, while the linoleum turns into powder. The traction roller is responsible for straightening the bent flax fibers with bark after compression, which also loosens the fibers.
[0019] 6. The extruded coarse hemp fibers with bark produce a large amount of dust. Therefore, a fan is installed on the top of the outer shell of this device. Optionally, a suction fan can also be installed at the bottom of the outer shell. A dust collection bag is installed below the waste port, and a high-pressure spray gun is added to the output port to blow out the dust hidden inside the coarse hemp fibers with bark.

[0028] Please see Figures 1-5 In this embodiment, the integrated hemp-beating machine is provided with a drying chamber 1, a crushing chamber 2, and a separation component 3 in sequence along the raw material movement direction. The separation component 3 includes a second conveyor belt 31, a protective shell 33, a first threaded rod 36, and a separation device 37. The second conveyor belt 31 is connected to the output port 23 of the crushing chamber 2. The bottom of the connecting frame 32 is fixed to the input end of the second conveyor belt 31, and the top of the connecting frame 32 is rotatably engaged with the protective shell 33. A first motor 35 is fixed inside the protective shell 33. One end of the first threaded rod 36 is fixed to the output shaft of the first motor 35, and the other end of the first threaded rod 36 is rotatably engaged with the inner wall of the protective shell 33. A first strip hole 34 is opened at the bottom of the protective shell 33, and the top of the separation device 37 passes through the first strip hole 34 and is threadedly engaged with the first threaded rod 36.
[0029] This device achieves continuous processing of raw materials through a segmented structure. The drying chamber 1 serves as the initial processing unit, with uniformly distributed heat sources inside, using hot air circulation to initially dry the raw materials. The input port 22 of the crushing chamber 2 receives the dried raw materials via the first conveyor belt 5, forming a continuous connection from the initial processing stage to the intermediate processing stage. The crushing chamber 2 crushes the coarse hemp fibers with bark, achieving a "hemp-beating" effect. The crushed coarse hemp fibers with bark are then fed into the separation component 3. In its initial state, the separation device 37 is positioned close to one end of the crushing chamber 2. During operation, the separation device 37 reciprocates on the surface of the first threaded rod 36, and its movement speed differs from that of the second conveyor belt 31. This allows the separation device 37 to separate the coarse hemp fibers output from the crushing chamber 2, forming multiple relatively independent coarse hemp fibers.
[0030] Furthermore, the bottom of the drying chamber 1 is connected to the input port 22 of the crushing chamber 2 via the first conveyor belt 5.
[0031] The drying chamber 1 feeds the dried flax fibers with bark into the crushing chamber 2 via the first conveyor belt 5. The drying chamber 1 then bakes the dried flax fibers with bark again at a temperature of 60-100 degrees Celsius, which is considered safe. Excessive temperature can easily cause a fire. The drying process mainly involves shaping and hardening the fibers.
[0032] Furthermore, the crushing chamber 2 includes a first outer shell 21, inside which a first crushing wheel 24 and a second crushing wheel 25 and a traction wheel 26 for assisting the movement of raw materials are arranged in parallel; the surfaces of the first crushing wheel 24 and the second crushing wheel 25 are provided with spiral protrusions in different directions; a waste outlet 27 is provided at the bottom of the first outer shell 21.
[0033] The traction wheel 26 at the outlet of the compaction chamber 2 is adjacent to the separation device 37 at the initial position. The first compaction wheel 24 and the second compaction wheel 25 compress the flax fibers with bark in different directions, resulting in a better compression effect. The width of the flax fibers with bark is customized according to production needs and the size of the equipment. When the flax fibers with bark are laid flat, the ends overlap, so that the thickness is approximately uniform. Because the thickness and length of the flax fibers with bark are different at the beginning and end, the dried and hardened flax fibers with bark need to be compressed to change their shape. Due to the difference in flexibility between the dried cortex and the fiber, the fibers of the flax fibers with bark do not separate from the cortex after compression, while the linoleum turns into powder. The traction wheel 26 is responsible for straightening the bent flax fibers with bark after compression, and the flax fibers with bark become loose while being straightened.
[0034] Furthermore, at least one fan 28 is provided at the top of the inner cavity of the first housing 21.
[0035] The extruded coarse hemp fibers with skin generate a large amount of dust, so a fan 28 is provided above the first housing 21. Optionally, a suction fan can also be provided at the bottom of the first housing 21, and a dust collection bag is provided below the waste port 27.
[0036] Furthermore, a high-temperature spray gun is installed at the output port 23 of the compaction chamber 2.
[0037] In addition, a high-pressure spray gun blows out the dust hidden inside the coarse hemp fibers with the skin on.
[0038] Furthermore, the separating device 37 includes a threaded sleeve 371 that is threaded to the outer wall of the first threaded rod 36. One end of the connecting rod 372 is fixed to the top of the threaded sleeve 371, and the other end of the connecting rod 372 is fixed to the top of the fixing frame 373 after passing through the first strip hole 34. A plurality of separating rods 374 are fixed at the bottom of the fixing frame 373. The bottom of the separating rods 374 is clearance-fitted with the surface of the second conveyor belt 31.
[0039] During the reciprocating motion of the separating rod 374, rows of coarse hemp fibers that are stuck together can be separated to achieve the effect of separating multiple coarse hemp fibers.
[0040] Furthermore, a sorting chamber 4 is also provided between the drying chamber 1 and the compaction chamber 2. The sorting chamber 4 includes a second outer shell 41. A second motor 42 is fixed in the middle of the inner cavity of the second outer shell 41. The output shaft of the second motor 42 is fixed to one end of a second threaded rod 43. The other end of the second threaded rod 43 passes through the middle of the mounting plate 44 and is rotatably connected to the inner wall of the second outer shell 41. Guide rods 47 are symmetrically fixed on both sides of the mounting plate 44. Both ends of the guide rods 47 are fixed to the inside of the second outer shell 41. Multiple guide rods are fixed to the top of the mounting plate 44. A cylinder 45 has a mounting plate 44 at its bottom and is fixed to a pressing plate 46. The bottom of the pressing plate 46 is provided with a soft rubber layer, which can be made of flexible and elastic deformable materials such as rubber or sponge. This allows the soft rubber layer to deform and adapt to the irregular shape of the coarse hemp fibers when the pressing plate 46 presses down. When in use, the coarse hemp fibers are bundled into bundles with gaps between them. When the pressing plate 46 presses down, the deformable soft rubber layer can automatically insert into the gaps.
[0041] The dried hemp fibers are relatively dry and easily break when directly crushed. Therefore, a sorting chamber 4 is set between the drying chamber 1 and the crushing chamber 2. After the hemp fibers enter the sorting chamber 4, the cylinder 45 first pushes the pressing plate 46 downward so that the pressing plate 46 comes into contact with the hemp fibers. Then, the second motor 42 is driven. The second motor 42 drives the pressing plate 46 to move laterally through the second threaded rod 43, the mounting plate 44, and the cylinder 45 in sequence. This allows the pressing plate 46 to cooperate with the soft rubber layer at its bottom to roll the bundled hemp fibers into a cylindrical shape, thus preventing the hemp fibers from breaking during crushing.
[0042] The method of using this utility model is as follows:
[0043] Drying chamber 1 serves as the initial processing unit, and its inner cavity is equipped with uniformly distributed heat source devices to perform preliminary drying of raw materials through hot air circulation.
[0044] After the coarse hemp fiber enters the finishing chamber 4, the cylinder 45 first pushes the pressing plate 46 downward so that the pressing plate 46 comes into contact with the coarse hemp fiber. Then, the second motor 42 is driven. The second motor 42 drives the pressing plate 46 to move laterally through the second threaded rod 43, the mounting plate 44, and the cylinder 45 in sequence, so that the pressing plate 46 rolls the flat coarse hemp fiber into a cylindrical shape to prevent the coarse hemp fiber from breaking during the rolling process.
[0045] The input port 22 of the crushing chamber 2 receives the dried raw material through the first conveyor belt 5, forming a continuous connection from the first stage of processing to the middle stage. The crushing chamber 2 squeezes and crushes the coarse hemp fiber with bark to achieve the effect of "hemp beating". The coarse hemp fiber with bark after beating is input into the separation component 3.
[0046] In the initial state of the separation component 3, the separation device 37 is close to one end of the crushing chamber 2. In use, the separation device 37 reciprocates on the surface of the first threaded rod 36, and the speed of the separation device 37 is different from the speed of the second conveyor belt 31. The separation device 37 can separate the coarse hemp fibers output from the crushing chamber 2 to form multiple relatively independent coarse hemp fibers.
[0047] When using this device, the ramie veneer can be cleaned in one pass, but the ramie fibrous residue requires multiple squeezes to remove. Alternatively, the number of rolling wheels can be increased within the device to achieve a one-pass degumming effect. The main function of this equipment is to remove the ramie veneer. The removal effect of the fibrous residue is not yet as good as that of a degumming workshop. However, ramie treated with this device can reduce the workload and pollution in the degumming workshop when it enters the workshop.
[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
