Description

Technical Field

[0001] This utility model belongs to the field of peeling equipment technology, and more specifically it relates to a straightening and screening component for a hemp peeling machine. Background Technology

[0002] Ramie is an important natural fiber crop with wide applications in textiles, ropes, and industrial materials. To improve production efficiency, ramie stripping machines are commonly used in mechanized agricultural production to process ramie plants, removing their outer husks to obtain the fibers.

[0003] However, while traditional hemp stripping machines can complete the basic hemp stripping process, they have the following problems in the process:

[0004] 1. Difficulty in handling bent ramie stalks: Many ramie plants are bent during their growth, which can easily lead to poor feeding, blockage, or even incomplete stripping when directly fed into the roller pressing device;

[0005] 2. Poor diameter adaptability: Existing hemp stripping machines lack an effective screening and adaptation mechanism for hemp stalks of different diameters, often resulting in mixed processing of coarse and fine stalks, causing insufficient roller pressure or excessive compression;

[0006] 3. Incomplete straightening and shaping: The lack of a dedicated straightening and shaping process causes bent hemp stalks to easily spring back during the stripping process, affecting the subsequent stripping quality.

[0007] Therefore, there is an urgent need for a straightening and screening component for hemp stripping machines, which can straighten, shape, and screen the diameter of hemp stalks before stripping, thereby improving the processing efficiency and stripping quality of the hemp stripping machine. Utility Model Content

[0008] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a straightening and screening component for a hemp stripping machine, which has the advantages of straightening and shaping the hemp stalks and screening their diameter before stripping, thereby improving feeding smoothness and stripping quality.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A straightening and screening assembly for a hemp stripping machine includes: a hemp stripping machine body and a feeding inlet disposed on the hemp stripping machine body. A diameter screening mechanism and a straightening and correcting mechanism are provided at the front end of the feeding inlet. The straightening and correcting mechanism is fixed to the front end of the diameter screening mechanism by a first mounting platform. The straightening and correcting mechanism includes an extrusion and shaping component, a feed inlet, a roller pressing and shaping component, and a pushing component. The diameter screening mechanism is disposed between the feeding inlet and the straightening and correcting mechanism.

[0011] The advantages of this scheme are at least as follows: By setting a diameter screening mechanism at the front end of the feeding inlet, the ramie plants can be pre-screened according to the stem diameter before entering the straightening and shaping mechanism, preventing excessively thick or thin plants from directly entering the subsequent mechanism. This improves the adaptability and processing accuracy of the entire machine. The straightening and shaping mechanism includes an extrusion shaping component and a roller shaping component, which can effectively correct the shape of the ramie stem, ensure uniform force during subsequent fiber stripping, reduce fiber damage, and increase the ramie yield. At the same time, the feeding component can achieve automatic feeding, reduce manual intervention, and improve continuous operation efficiency. This allows the ramie stripping machine to straighten and shape the ramie stems and screen their diameter before stripping, thereby improving the smoothness of feeding and the quality of stripping.

[0012] The present invention is further configured such that: the extrusion shaping assembly is mounted on the top of the first mounting platform via a second mounting platform; the extrusion shaping assembly includes an abutment block, a moving block, and an extrusion driving assembly; the end face of the abutment block is provided with a first V-groove, the end face of the moving block is provided with a second V-groove opposite to the first V-groove, and the output end of the extrusion driving assembly is connected to the moving block.

[0013] The advantages of this scheme are at least as follows: by setting the first V-shaped groove and the second V-shaped groove on the abutting block and the moving block respectively, a symmetrical V-shaped clamping structure is formed, which can automatically center and circumferentially limit the bending ramie plants of different diameters, and prevent the ramie stalks from slipping or deviating during the squeezing process.

[0014] The extrusion drive component pushes the moving block toward the fixed abutment block, causing the two V-grooves to gradually close. This applies controllable radial pressure to the bent hemp stalk, forcing it to undergo plastic deformation, significantly improving the initial curvature, providing a good foundation for subsequent roll forming, and reducing the risk of clogging and breakage during the peeling process.

[0015] The present invention is further configured such that: a rolling roller is provided inside the movable block, the rolling roller is slidably installed inside the movable block via a U-shaped seat, and a rolling roller drive assembly is connected to one side of the movable block via a mounting seat.

[0016] The advantages of this scheme are at least as follows: by adding rolling rollers inside the moving block and using a rolling roller drive assembly, it can automatically match and fit ramie of different diameters and degrees of curvature, improving the straightening effect. At the same time, the linkage between the rolling roller drive assembly and the moving block not only enhances the continuity and automation of the straightening operation, but also provides a smoother transition for the subsequent pushing and rolling processes of the ramie plants, improving the overall efficiency and quality of straightening and shaping.

[0017] The present invention is further configured such that: the roller pressing and shaping assembly includes a mounting frame, a first roller pressing assembly, a second roller pressing assembly, a first roller pressing drive assembly, and a second roller pressing drive assembly; the first roller pressing assembly includes two first roller pressing wheels arranged parallel to each other, wherein one of the first roller pressing wheels is adjustablely mounted on the mounting frame via a first sliding seat and a first screw; the second roller pressing assembly includes two mutually parallel second roller pressing wheels, wherein the two second roller pressing wheels are adjustablely mounted on the mounting frame via a second sliding seat and a second screw.

[0018] The advantages of this scheme are at least as follows: by setting the first and second roller pressing components on the mounting frame and forming a mutually perpendicular arrangement in space, the ramie plants can be straightened in both the vertical and horizontal directions, which greatly improves the comprehensiveness and accuracy of the shaping; both the first and second roller pressing rollers can be adjusted by sliding seats and screws, and the gap can be flexibly adjusted according to the different diameters of the ramie plants, thus being compatible with plants of different specifications and improving the adaptability of the equipment.

[0019] The present invention is further configured such that: both the ends of the first screw and the second screw are provided with knobs, and the circumference of the knobs is provided with knurling.

[0020] The advantages of this scheme are at least as follows: by setting a knob, the knob can make the operator rotate the first screw and the second screw more easily. At the same time, the knurling on the knob can increase the friction between the user and the knob, preventing the knob from slipping when turning.

[0021] The present invention is further configured such that: the feed inlet has a curved channel structure, and a blocking device is provided at its bottom; the blocking device includes two sets of electric push rods arranged in parallel at the top and bottom, and the two sets of electric push rods alternately extend and retract.

[0022] The advantages of this scheme are at least as follows: by designing the feed inlet as a curved channel structure and setting a blocking device at its bottom with alternating extension and retraction of two sets of electric push rods, orderly and single-stalk feeding of hemp stalks can be achieved; the curved channel helps guide the directional flow of hemp stalks, while the alternating action of the electric push rods forms a rhythmic control of "opening and closing", effectively blocking the premature entry of subsequent hemp stalks and preventing jamming or blockage caused by multiple hemp stalks rushing in at the same time.

[0023] The present invention is further configured such that: the diameter screening mechanism includes a first roller conveyor belt, a second roller conveyor belt, and a guide plate; the first roller conveyor belt is divided into a fine diameter conveying channel and a coarse diameter conveying channel by a partition plate; the second roller conveyor belt is disposed above the first roller conveyor belt, and its rollers are arranged perpendicularly to the rollers of the first roller conveyor belt in space; the guide plate is located below the second roller conveyor belt.

[0024] The advantages of this scheme are at least as follows: After straightening and shaping, the ramie plants fall onto the second roller conveyor belt. When the diameter of the ramie plant is larger than the gap between two adjacent rollers on the second roller conveyor belt, the ramie plant is conveyed by the rotating rollers of the second roller conveyor belt, thus transporting the ramie plant to the end of the second roller conveyor belt. The guide plate guides the ramie plant and rolls it into the coarse-diameter conveying channel of the first roller conveyor belt. When the diameter of the ramie plant is smaller than the gap between two adjacent rollers on the second roller conveyor belt, the ramie plant passes through the gap between the two adjacent rollers and falls into the fine-diameter channel of the first roller conveyor belt, thus being conveyed to the feed inlet by the first roller conveyor belt for the sorted ramie plants to be separated by roller pressing and peeling.

[0025] The present invention is further configured such that: the pushing assembly includes a pushing plate and a push rod driving assembly, the pushing plate is slidably installed in the first V-groove, and the output end of the push rod driving assembly is fixedly connected to the pushing plate.

[0026] The advantages of this scheme are at least as follows: the curved guide surface can prevent the ramie plants from deviating during the pushing process, and the wear-resistant layer covering the surface of the curved guide surface prevents the pusher plate from directly contacting the ramie plants, thereby reducing frictional damage between the ramie plants and the pusher plate during the pushing process.

[0027] The present invention is further configured such that: the front end of the pusher plate is provided with an arc-shaped guide surface, and the arc-shaped guide surface faces the roll forming assembly.

[0028] The advantages of this scheme are at least as follows: the curved guide surface can prevent the ramie plants from deviating during the pushing process, and the wear-resistant layer covering the surface of the curved guide surface prevents the pusher plate from directly contacting the ramie plants, thereby avoiding frictional damage between the ramie plants and the pusher plate during the pushing process.

[0029] The present invention is further configured such that: the surface of the arc-shaped guide surface is covered with a wear-resistant layer, and the surface of the wear-resistant layer is provided with protrusions.

[0030] The advantages of this scheme are at least as follows: by covering the surface of the arc-shaped guide surface with a wear-resistant layer and setting protrusions, not only can the wear resistance of the guide surface be significantly improved and the service life of the component be extended, but the limiting and frictional effect of the protrusions can also be used to effectively guide and prevent the passing hemp stalks, so as to avoid the hemp stalks from deviating or slipping during the conveying and straightening process, thereby ensuring the stability of the feeding.

[0031] In summary, this utility model has at least the following advantages:

[0032] 1. By setting up a straightening and straightening mechanism, before stripping the bent ramie plants, the ramie plants first fall one by one through the feed inlet of the curved channel structure, and the blocking device controls the flow to prevent multiple plants from piling up. After entering the extrusion and shaping component, they undergo preliminary straightening through extrusion and shaping, and then undergo secondary straightening and shaping through the roller pressing and shaping component. This effectively eliminates the bending of the ramie plants, so that they remain straight before entering the subsequent roller pressing device and stripping component. This ensures stability during the stripping process and avoids problems such as broken ramie or incomplete stripping, thereby improving the integrity of ramie extraction.

[0033] 2. By setting up a diameter screening device, the ramie plants can be pre-treated after shaping and before entering the feed inlet. The ramie is graded according to its diameter and conveyed to the subsequent roller pressing assembly. This avoids fiber damage or insufficient roller pressing caused by uneven force on plants of different diameters during the roller pressing process, effectively improving the uniformity and processing quality of subsequent ramie stripping. At the same time, the grading process improves the adaptability of the feed and the overall operating efficiency of the equipment.

[0034] 3. By setting two sets of parallel electric push rods at the bottom of the feed inlet and using an alternating extension and retraction action, precise control of releasing ramie plants one by one can be achieved, thus avoiding the accumulation and jamming caused by multiple plants entering the straightening and shaping mechanism at the same time.

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of this utility model and the features thereof can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] Example 1

[0045] like Figure 1 As shown, a straightening and screening assembly for a flax peeling machine includes a flax peeling machine body 1 and a feeding inlet 2 disposed on the flax peeling machine body 1. The flax peeling machine body 1 includes a roller pressing device 3 and a peeling assembly 4, which are disposed on the frame of the flax peeling machine body 1. A diameter screening mechanism 5 and a straightening and shaping mechanism 6 are provided at the front end of the feeding inlet 2. The straightening and shaping mechanism 6 is fixed to the front end of the diameter screening mechanism 5 by a first mounting platform 7. The straightening and shaping mechanism 6 includes a compression shaping assembly 601, a feed inlet 602, a roller pressing and shaping assembly 603, and a pushing assembly 604. The diameter screening mechanism 5 is disposed between the feeding inlet 2 and the straightening and shaping mechanism 6. The roller pressing device 3 and the peeling assembly 4 are both driven to rotate by a drive device, wherein the drive device is a belt and gear set, which can be driven by a diesel engine or a gasoline engine, thereby driving the roller pressing assembly and the peeling assembly 4 to rotate. A protective shell is also installed on the outer periphery of the belt and gear set.

[0046] Example 2

[0047] like Figure 2 , Figure 3 , Figure 4 As shown, the extrusion shaping assembly 601 is mounted on top of the first mounting platform 7 via the second mounting platform 8. The extrusion shaping assembly 601 includes an abutment block 6011, a moving block 6012, and an extrusion drive assembly 6013. The end face of the abutment block 6011 is provided with a first V-groove 9, and the end face of the moving block 6012 is provided with a second V-groove 10 opposite to the first V-groove 9. The output end of the extrusion drive assembly 6013 is connected to the moving block 6012. The moving block 6012 is provided with a rolling roller 6014 inside, which is slidably mounted in the moving block 6012 via a U-shaped seat. One side of the moving block 6012 is connected to a rolling roller drive assembly 6016 via a mounting base 6015. The rolling roller drive assembly 6016 is not limited to one specific form; it can be a hydraulic cylinder, a hydraulic oil cylinder, or an electric push rod, etc. Any existing drive structure that can achieve linear drive and drive the U-shaped seat and the roller to make linear movement is applicable.

[0048] In some embodiments, the abutment block 6011 is provided with buffer components at both ends, wherein the buffer components include sliding rods slidably mounted at both ends of the abutment block 6011, one end of the sliding rod is provided with a buffer plate, and the other end is provided with a limiting block. A buffer spring is fitted on the outer surface of the sliding rod, and the buffer spring is located between the abutment plate and the abutment block 6011. The side of the buffer plate facing the moving block 6012 is an arc-shaped abutment surface. When the arc-shaped abutment surface contacts the ramie plant, it can disperse the force and avoid damage to the plant epidermis due to concentrated squeezing. The limiting block is fixed to the end of the abutment block 6011 to limit the maximum extension stroke of the sliding rod, ensuring that the buffer plate can move within a preset range when impacted or deflected by the plant, and avoiding excessive displacement that affects the shaping effect.

[0049] like Figure 3 , Figure 4 As shown, the roller pressing and shaping assembly 603 includes a mounting frame 6031, a first roller pressing assembly 6032, a second roller pressing assembly 6033, a first roller pressing drive assembly 6034, and a second roller pressing drive assembly 6035. The first roller pressing assembly 6032 includes two first roller pressing rollers arranged parallel to each other, one of which is adjustablely mounted on the mounting frame 6031 via a first sliding seat 11 and a first screw 12. The second roller pressing assembly 6033 includes two parallel second roller pressing rollers, which are adjustablely mounted on the mounting frame 6031 via a second sliding seat 13 and a second screw 14. The first roller pressing assembly 6032 and the second roller pressing assembly 6033 are arranged perpendicularly to each other in space, realizing bidirectional straightening of ramie plants in both vertical and horizontal directions, greatly improving the comprehensiveness and accuracy of shaping.

[0050] Both the first screw 12 and the second screw 14 are equipped with knobs at their ends. The knobs are knurled around their circumference. The knobs allow the operator to rotate the first screw 12 and the second screw 14 more easily. At the same time, the knurling on the knobs increases the friction between the user and the knobs, preventing the knobs from slipping when turned.

[0051] The feed inlet 602 has a curved channel structure, and a blocking device 6021 is provided at its bottom. The blocking device 6021 includes two sets of electric push rods arranged parallel to each other. The two sets of electric push rods alternately extend and retract. In some preferred embodiments, a vibration device is also installed on the side wall of the feed inlet 602. Through the periodic vibration of the vibration device, the curved ramie plant can fall smoothly into the extrusion and shaping component 601, thereby reducing the risk of material blockage during feeding and further ensuring the continuity and stability of the feeding process. The vibration device can be an eccentric motor type vibration device, which generates an unbalanced centrifugal force when the motor rotates by installing an eccentric block on the motor shaft, thereby driving the side wall of the feed inlet 602 to vibrate periodically; or it can be a pneumatic vibrator, which uses compressed air to drive the piston or vibrating hammer to reciprocate, so that the feed inlet 602 generates high-frequency vibration.

[0052] Example 3

[0053] like Figure 6 As shown, the pusher assembly 604 includes a pusher plate 6041 and a pusher drive assembly 6042. The pusher plate 6041 is slidably installed in the first V-groove 9, and the output end of the pusher drive assembly 6042 is fixedly connected to the pusher plate 6041. The front end of the pusher plate 6041 is provided with an arc-shaped guide surface (not shown in the figure), which faces the roller forming component 603. The function of the arc-shaped guide surface is to prevent the ramie plants from deviating during the pushing process. The wear-resistant layer covering the surface of the arc-shaped guide surface prevents the pusher plate 6041 from directly contacting the ramie plants, thereby reducing frictional damage between the ramie plants and the pusher plate 6041 during the pushing process. The surface of the arc-shaped guide surface is covered with a wear-resistant layer (not shown in the figure), and the surface of the wear-resistant layer is provided with protrusions. By covering the surface of the arc-shaped guide surface with a wear-resistant layer and setting protrusions, not only can the wear resistance of the guide surface be significantly improved and the service life of the component be extended, but the limiting and frictional effect of the protrusions can also effectively guide and prevent the passing ramie stalks, preventing the ramie stalks from deviating or slipping during the conveying and straightening process, thereby ensuring the stability of the feeding.

[0054] Example 4

[0055] like Figure 6As shown, the diameter screening device includes: a first roller conveyor belt 501, which is located at the front end of the feed inlet 2 and is divided into a fine diameter conveying channel and a coarse diameter conveying channel by a partition plate; a second roller conveyor belt 502, which is located above the first roller conveyor belt 501, and the rollers on the second roller conveyor belt 502 are arranged perpendicularly to the rollers on the first roller conveyor belt 501 in space, for screening the diameter of ramie plants; and a guide plate 503, which is located below the second roller conveyor belt 502, for guiding plants that have not passed through the second roller conveyor belt 502 into the first roller conveyor belt 501.

[0056] The spacing between the rollers on the second roller conveyor belt 502 is set according to the diameter range of the ramie plants, preferably larger than a preset medium diameter value. This allows ramie plants with a diameter smaller than the preset medium diameter to pass smoothly through the gap between adjacent rollers, while larger diameter ramie plants cannot pass through, thus achieving the screening of ramie of different diameters. Preferably, the spacing of the second roller conveyor belt 502 is adjustable to adapt to the screening requirements of ramie of different specifications. The rollers on the second roller conveyor belt 502 have several protrusions on their surfaces to increase the friction between the ramie plants and the rollers. It is worth mentioning that both the first roller conveyor belt 501 and the second roller conveyor belt 502 can be driven by a variable frequency motor, and their speed is adjustable.

[0057] Based on Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4, this utility model also provides a method for using a straightening and screening component for a hemp peeling machine, the specific steps of which are as follows:

[0058] S1 (Single Root Feed): The operator places the bent ramie plant at the feed inlet 602, and the plant falls one by one through the curved channel feed inlet 602; the feed inlet 602 constrains the posture of the plant to prevent it from becoming scattered and stuck; then the two sets of electric push rods of the blocking device 6021 alternately extend and retract to control the release of the bent plant one by one, ensuring that each plant enters the straightening and shaping mechanism 6 in sequence, and preventing multiple plants from entering at the same time and affecting the shaping effect.

[0059] S2 (Extrusion Shaping): The bent ramie plant enters the extrusion shaping component 601 and is positioned between the first V-groove 9 and the second V-groove 10. The moving block 6012 moves towards the abutment block 6011 under the action of the extrusion drive component 6013, achieving initial flattening of the bent part. Subsequently, the rolling roller 6014 generates linear motion under the action of the rolling roller drive component 6016 and closely adheres to the ramie plant, preparing for subsequent material pushing.

[0060] S3 (Pushing and Roller Shaping): After the pre-correction of extrusion shaping is completed, the ramie plant is pushed into the roller shaping assembly. Then, the bent and straightened ramie plant is subjected to longitudinal and transverse bidirectional roller pressing by the first roller pressing assembly 6032 and the second roller pressing assembly 6033 to completely shape the bent part and ensure that the plant is straight before entering the peeling stage.

[0061] S4 (Diameter Screening): After straightening and shaping, the ramie plants enter the diameter screening mechanism 5. Plants with smaller diameters fall into the fine diameter conveying channel through the gap of the second roller conveyor belt 502, while plants with larger diameters enter the coarse diameter channel along the first roller conveyor belt 501. This achieves diameter separation of the shaped and curved plants. Subsequently, the shaped ramie plants are fed into the ramie stripping machine body 1 through the feeding inlet 2 via the first roller conveyor belt 501 for stripping.

[0062] Through the above steps: the bent ramie plants are first squeezed and shaped, and then pushed and rolled for shaping. The combined use of squeezing and rolling shapes gradually straightens and shapes the bent plants, ensuring that the ramie plants entering the stripping stage are straight, improving the uniformity of stripping and fiber integrity. At the same time, this embodiment solves the problems of poor feeding, jamming, and even incomplete stripping caused by bent ramie plants directly entering the rolling device 3 in the prior art; it also solves the problem of insufficient or excessive rolling pressure caused by the lack of an effective screening and adaptation mechanism for ramie stalks of different diameters in existing stripping machines; and it also solves the problem of bent ramie stalks rebounding during the stripping process, affecting the subsequent stripping quality.

[0063] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0064] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
