Description

Technical Field

[0001] This invention belongs to the field of peeling machine technology, specifically relating to a device and method for cleaning the epidermis of pineapple plant stems. Background Technology

[0002] Pineapple fiber, due to its high strength, low density, good moisture absorption, and biodegradability, has become an ideal alternative material in textiles and composite materials. The market primarily uses fiber from pineapple leaves because leaf fiber is relatively easy to obtain. In contrast, pineapple stem fiber, due to its more rigid structure and high content of lignin and other binding substances, presents greater technical challenges in raw material acquisition, limiting its widespread application. Therefore, the main challenges in improving the utilization rate of pineapple stem fiber include:

[0003] First, most existing fiber extraction equipment is designed to process relatively soft plant materials, such as pineapple leaves or cotton. For the more rigid pineapple stem, which is often covered with soil, dust, and other impurities, traditional equipment may not be able to process it effectively, resulting in low fiber extraction efficiency.

[0004] Secondly, the outer skin of the pineapple stem contains relatively hard fibers, while the inner fibers are softer and easier to extract. Therefore, when processing pineapple stems, it is usually necessary to remove the outer skin first to facilitate further processing. However, due to the significant differences in the size and shape of pineapple plants, this diversity further increases the difficulty of processing the stem fibers. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a device and method for cleaning the epidermis of pineapple plant stems, so as to improve the extraction efficiency and quality of pineapple stem fiber, promote its widespread application in more fields, and thus improve the overall utilization rate of resources.

[0006] To solve the above-mentioned technical problems, the first technical solution of the present invention is a pineapple plant stem epidermis cleaning device, characterized in that: the epidermis cleaning device is composed of processing components, the processing components are composed of a conveying mechanism and an epidermis cutting mechanism, the conveying mechanism and the epidermis cutting mechanism are arranged opposite to each other, the conveying mechanism is provided with fixing members arranged at equal intervals, the fixing members are used for placing and fixing the plant stem; the epidermis cutting mechanism is used for cleaning one side of the plant stem epidermis; after the fixing members have completed the fixing of the plant stem, the plant stem is transported by the conveying mechanism, and the stem epidermis is cleaned when passing through the epidermis cutting mechanism, thus completing the cleaning of one side of the plant stem epidermis; the processing components respectively include a first processing component, a second processing component, a third processing component and a fourth processing component for cleaning different sides of the plant stem epidermis, so as to complete the comprehensive epidermis cleaning of the plant stem.

[0007] Preferably, the epidermal cutting mechanism is configured as follows: the epidermal cutting mechanism consists of a rotating frame and a cutter mounted on the rotating frame, the rotation axis of the rotating frame being parallel to the rotation axis of the conveying mechanism; the rotating frame is positioned with a lower center and higher ends, and the cutter is evenly distributed on the surface of the rotating frame; when the rotating frame rotates, it drives the cutter to perform arc-shaped cutting on the epidermis of the plant stem.

[0008] Preferably, the conveying mechanism is configured as follows: the conveying mechanism includes a transmission gear, on which a transmission chain is provided, and the fixing member is a spike fixedly disposed on the transmission chain; the fixing member is inserted into the plant stem to achieve the placement and fixation of the plant stem.

[0009] Preferably, to ensure smooth feeding of the conveying mechanism: the processing component is provided with an infeed and an outlet for restricting the movement of the plant stem. The infeed is used to restrict the movement of the plant stem and allow the fixing component to fix the plant stem. The outlet is used to restrict the movement of the plant stem and allow the fixing component to separate from the plant stem. The infeed is located near the infeed end of the first processing component and on one side of the epidermal cutting mechanism inside the first processing component. The outlet is located near the outlet end of the fourth processing component and on one side of the conveying mechanism inside the first processing component.

[0010] Furthermore, to ensure the movement of the plant stem between the conveying mechanisms: the plant stem sequentially passes through the first processing component, the second processing component, the third processing component, and the fourth processing component. Depending on the different processing surfaces of the plant stem, the transition can be divided into adjacent surface processing transition and opposite surface processing transition. During adjacent surface processing transition, the feeding component is also located at the feeding end of the rear processing component and on one side of the epidermal cutting mechanism within the rear processing component, and the discharging component is also located at the discharging end of the front processing component and on one side of the conveying mechanism within the front processing component. During opposite surface processing transition, the discharging component is also located at the discharging end of the front processing component and on one side of the conveying mechanism within the front processing component.

[0011] Furthermore, to ensure the feeding of plant stems of different sizes: the feeding component located on the feeding end of the first processing component is set on a spring lifting frame; the spring lifting frame allows the feeding component on the feeding end of the first processing component to adjust its position, so as to facilitate the cleaning of the epidermis of plant stems of different sizes.

[0012] Furthermore, a tensioning mechanism is added to ensure the stability of the conveying mechanism: the processing component is equipped with a tensioning mechanism for controlling the tension of the transmission chain, the tensioning mechanism includes an adjusting member, and the adjusting member is provided with a rotating member that contacts the transmission chain; the tension of the transmission chain is controlled by controlling the position of the adjusting member; the adjusting member is set on a shock-absorbing rod, and the shock-absorbing rod is used to prevent the transmission chain from falling off when cleaning the epidermis of the plant stem.

[0013] Furthermore, the tensioning mechanism is optimized to enable the equipment to process plant stems of different specifications: the adjusting components are located inside the transmission chain, and the adjusting components are a first adjusting component and a second adjusting component. The first adjusting component and the second adjusting component act on the transmission chain on both sides respectively. The first adjusting component, the second adjusting component, and the epidermal cutting mechanism are on the same straight line, and this straight line is parallel to the conveying direction of the conveying mechanism; the first adjusting component and the second adjusting component are both located at one end of the shock-absorbing rod, and the other end of the shock-absorbing rod is provided with a control component; the first adjusting component is close to the epidermal cutting mechanism, and the distance between the first adjusting component and the epidermal cutting mechanism is controlled by the control component to control the amount of epidermal cutting of the plant stem.

[0014] Furthermore, the skin cleaning equipment is also provided with a frame for installing the processing components, the frame being composed of a template and a template plate; the conveying mechanism and the skin cutting mechanism are both mounted on the template plate, the tensioning mechanism is mounted on the template, and the linear transmission component is provided between the tensioning mechanism and the template, the linear transmission component being used to control the position of the control component.

[0015] To solve the above-mentioned technical problems, technical solution two of the present invention provides a method for using a pineapple plant stem epidermis cleaning device, applying the epidermis cleaning device described in technical solution one, the method of use including:

[0016] S1. Adjust the tensioning mechanism and control the cutting depth of the pineapple plant stem by the peel cleaning equipment according to the size and shape of the pineapple plant stem to be treated.

[0017] S2. Place the stem of the pineapple plant into the fixing part on the conveying mechanism, and fix it by inserting the spikes into the stem to ensure that the plant is firmly clamped.

[0018] S3. Start the conveying mechanism to move the plant along the predetermined path. When it passes the epidermal cutting mechanism, the rotating frame rotates and drives the cutter to make an arc-shaped cut on one surface of the plant stem to complete the single-sided epidermal cleaning.

[0019] S4. The plant stem passes through the first processing component, the second processing component, the third processing component, and the fourth processing component in sequence. Each component is responsible for cleaning a different surface, thereby completing a comprehensive epidermal cleaning.

[0020] S5. When the plant stem reaches the discharge part of the fourth processing component, the discharge part restricts the movement of the plant, causing the fixing part to separate from the plant, and the pineapple plant stem is collected after the skin is cleaned.

[0021] The main technical effects of this invention are reflected in the following aspects:

[0022] This invention achieves comprehensive epidermal cleaning of the pineapple plant stem by using four processing components (first, second, third, and fourth processing components), each responsible for cleaning a different surface. This design significantly improves cleaning efficiency and reduces the time and steps required for cleaning a single surface. The epidermal cutting mechanism uses a combination of a rotating frame and a cutter, which cuts along an arc-shaped path on the pineapple stem. This design mimics the action of manual cutting, more naturally conforming to the curve of the pineapple stem, achieving uniform and smooth epidermal removal, and improving the cleaning effect.

[0023] This invention can adapt to pineapple stems of different sizes and shapes. By flexibly adjusting the fixing components, tensioning mechanism, and cutting depth, it ensures effective cleaning of various types of stems. This makes the equipment suitable not only for large-scale industrial production but also for small-batch processing in small farms or laboratories. Attached Figure Description

[0033] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0034] Example 1

[0035] See Figure 1 This embodiment discloses a pineapple plant stem epidermis cleaning device. The epidermis cleaning device consists of a processing component 1, which comprises a conveying mechanism 2 and an epidermis cutting mechanism 3. The conveying mechanism 2 and the epidermis cutting mechanism 3 are arranged opposite to each other. The conveying mechanism 2 is provided with equidistantly arranged fixing members 21, which are used for placing and fixing the plant stem. The epidermis cutting mechanism 3 is used for cleaning one side of the plant stem epidermis. After the fixing members 21 have completed fixing the plant stem, the plant stem is transported by the conveying mechanism 2 and the epidermis of the stem is cleaned when passing through the epidermis cutting mechanism 3, thus completing the cleaning of one side of the plant stem epidermis.

[0036] See Figure 2To achieve comprehensive cleaning of the pineapple stem's epidermis, this embodiment adds additional processing components 1 (second, third, and fourth processing components 14), each responsible for cleaning a different surface. These components are arranged around the conveying path, forming a closed-loop system, allowing the pineapple stem to complete epidermal cleaning of all four surfaces in a single pass. The processing components 1 respectively include a first processing component 11, a second processing component 12, a third processing component 13, and a fourth processing component 14 for cleaning the epidermis of different surfaces of the plant stem, thus completing comprehensive epidermal cleaning of the plant stem.

[0037] See Figure 3 , Figure 4 The conveying mechanism 2 includes a transmission gear 22, on which a transmission chain 23 is mounted. The fixing member 21 is a spike fixedly mounted on the transmission chain 23. The combination of the transmission gear 22 and the transmission chain 23 ensures that the pineapple stem can move smoothly during processing. The precise meshing of the gears ensures the stable operation of the chain, avoiding slippage or jumping, making the entire conveying system run more smoothly. The distance between the spikes can be adjusted according to the different sizes of pineapple stems to ensure that each stem is properly fixed. The fixing member 21 is inserted into the plant stem to place and fix the plant stem. The fixing member 21 adopts a spike design, which can be directly inserted into the pineapple stem, providing a very firm fixing point; at the same time, it also takes into account the hardness and shape of the pineapple stem, effectively preventing displacement or rotation during cutting.

[0038] The system incorporates an infeed member 24 and an outlet member 25: the infeed member 24 restricts the movement of the plant stem, ensuring that the fixing member 21 (spiky) can accurately insert and secure the plant stem; the outlet member 25 restricts the movement of the plant stem, ensuring that the fixing member 21 (spiky) can safely detach from the plant stem. The design of the infeed member 24 and the outlet member 25 effectively restricts the movement of the plant stem during processing, ensuring that the fixing member 21 (spiky) can accurately insert and separate, thus improving the stability and reliability of the entire system. Precise clamping and securing ensure the accuracy of the cutting process, reducing the risk of uneven cutting or damage to internal fibers caused by stem movement.

[0039] The processing component 1 is provided with a feeding component 24 and a discharging component 25 for restricting the movement of the plant stem. The feeding component 24 is used to restrict the movement of the plant stem and allow the fixing component 21 to fix the plant stem. The discharging component 25 is used to restrict the movement of the plant stem and allow the fixing component 21 to separate from the plant stem. The feeding component 24 is located near the feeding end of the first processing component 11 and is located on one side of the epidermal cutting mechanism 3 inside the first processing component 11. The discharging component 25 is located near the discharging end of the fourth processing component 14 and is located on one side of the conveying mechanism 2 inside the first processing component 11. The plant stem passes sequentially through the first processing component 11, the second processing component 12, the third processing component 13, and the fourth processing component 14. Depending on the different processing surfaces of the plant stem, the transition can be divided into adjacent surface processing transition and opposite surface processing transition. During adjacent surface processing transition, the feed component 24 is also located at the feed end of the rear processing component 1 and on one side of the inner epidermal cutting mechanism 3 of the rear processing component 1, while the discharge component 25 is also located at the discharge end of the front processing component 1 and on one side of the inner conveying mechanism 2 of the front processing component 1. During opposite surface processing transition, the discharge component 25 is also located at the discharge end of the front processing component 1 and on one side of the inner conveying mechanism 2 of the front processing component 1. In this case, the discharge component 25 also functions as the feed component 24, providing support for the plant stem to enter the next processing component 1.

[0040] The feed element 24 located at the feed end of the first processing component 11 is mounted on a spring lifting frame 26. The spring lifting frame 26 utilizes the elastic properties of springs to automatically adjust the height of the feed element 24 according to the diameter of the plant stem. When a smaller diameter stem enters, the spring naturally compresses, causing the feed element 24 to descend to an appropriate position; when a larger diameter stem enters, the spring extends, causing the feed element 24 to rise to a higher position. The spring lifting frame 26 allows for position adjustment of the feed element 24 at the feed end of the first processing component 11, facilitating the cleaning of the stem skin of different sizes. The spring force can be preset to ensure that the clamping force applied by the feed element 24 to the plant stem is moderate, neither too tight causing damage nor too loose affecting the fixing effect.

[0041] See Figure 5The peel cutting mechanism 3 consists of a rotating frame 31 and cutters 32 mounted on the rotating frame 31. The rotation axis of the rotating frame 31 is parallel to the rotation axis of the conveying mechanism 2. The rotating frame 31 is positioned with a lower center and higher ends, and the cutters 32 are evenly distributed on the surface of the rotating frame 31, ensuring effective contact with the pineapple stem's peel throughout the rotation process. This arrangement ensures that the peel of each part is cleaned evenly without omissions or over-cleaning. When the rotating frame 31 rotates, it drives the cutters 32 to perform an arc-shaped cut on the plant stem's peel; mimicking the action of manual cutting, it can more naturally conform to the curve of the pineapple stem, thus achieving a more uniform and smooth peel removal. At the same time, the arc-shaped cutting path helps reduce potential damage to the internal fibers because the cutters 32 contact and remove the peel in a gentle manner, rather than cutting at right angles or sharp angles, reducing the pulling or tearing of the fibers.

[0042] See Figure 6 The processing component 1 is equipped with a tensioning mechanism 4 for controlling the tension of the transmission chain 23. The tensioning mechanism 4 includes an adjusting component 41, on which a rotating component 42 contacts the transmission chain 23. The rotating component 42 guides the movement of the transmission chain 23, reduces friction, and prevents the chain from shifting or jamming during operation. By controlling the position of the adjusting component 41, the tension of the transmission chain 23 can be controlled, changing its tightness to ensure it maintains appropriate tension. The adjusting component 41 is mounted on a shock-absorbing rod 43, which prevents the transmission chain 23 from detaching during cleaning of the plant stem's epidermis. The main function of the shock-absorbing rod 43 is to absorb vibrations and impacts generated by the transmission chain 23 during operation, preventing the chain from detaching or being damaged due to excessive vibration. The shock-absorbing rod 43 is typically equipped with springs or other elastic elements to buffer external forces and maintain system stability to a certain extent.

[0043] See Figure 7The adjusting element 41 is located inside the transmission chain 23. The adjusting elements 41 are a first adjusting element 411 and a second adjusting element 412, which act on the transmission chain on both sides. The first adjusting element 411, the second adjusting element 412, and the epidermal cutting mechanism 3 are on the same straight line, parallel to the conveying direction of the conveying mechanism 2. This dual-sided adjustment design ensures that the transmission chain 23 remains balanced during operation, preventing it from becoming too loose or too tight after adjustment. Both the first adjusting element 411 and the second adjusting element 412 are located at one end of the shock-absorbing rod 43, and a control element 44 is located at the other end of the shock-absorbing rod 43. The first adjusting element 411 is close to the epidermal cutting mechanism 3, and the control element 44 controls the distance between the first adjusting element 411 and the epidermal cutting mechanism 3, thereby controlling the amount of epidermal cutting on the plant stem. Combined with a sensor and control system, the distance can be automatically adjusted according to the different diameters and shapes of pineapple stems, ensuring optimal results for each cut. For example, for thicker stems, the spacing can be increased to reduce the amount of cutting; for thinner stems, the spacing can be decreased to increase the amount of cutting.

[0044] See Figure 8 The surface cleaning equipment also includes a frame 5 for mounting the processing component 1. The frame 5 consists of a template 51 and a template plate 52. The template 51 is the main supporting structure of the entire equipment, providing mechanical strength and stability. It is typically made of high-strength steel or aluminum alloy, ensuring the durability of the equipment during long-term operation. The template plate 52 is fixed to the template 51 and is used to mount the conveying mechanism 2 and the surface cutting mechanism 3. The design of the template plate 52 takes into account flatness and rigidity, ensuring precise installation and stable operation of each component. The combined design of the template 51 and template plate 52 gives the equipment a modular feature, facilitating assembly, disassembly, and maintenance. Simultaneously, this design allows for flexible adjustment of the position of each component according to actual needs, improving the equipment's versatility and adaptability. Both the conveying mechanism 2 and the skin cutting mechanism 3 are mounted on the template 52, and the tensioning mechanism 4 is mounted on the frame 51. A linear transmission component is provided between the tensioning mechanism 4 and the frame 51. This linear transmission component controls the position of the control element 44, allowing the tensioning mechanism 4 to be adjusted independently of other components, preventing vibrations from the conveying mechanism 2 or the skin cutting mechanism 3 from affecting its operation. The linear transmission component controls the position of the control element 44, ensuring that the tensioning mechanism 4 can accurately adjust the tension of the transmission chain 23. Common linear transmission components include lead screws, guide rails, cylinders, or electric actuators, with the specific choice depending on the equipment requirements and application scenario.

[0045] Example 2

[0046] This embodiment discloses a method for using a pineapple plant stem epidermis cleaning device, applying the epidermis cleaning device described in Embodiment 1. The method includes:

[0047] S1. Adjust the tensioning mechanism according to the size and shape of the pineapple plant stem to be processed. 4. Control the cutting depth of the peel cleaning equipment on the pineapple plant stem to ensure the best processing effect.

[0048] S2. Place the stem of the pineapple plant in the fixing part 21 on the conveying mechanism 2, and fix it by inserting the spikes into the stem of the plant to ensure that the plant is firmly clamped.

[0049] S3. Start the conveying mechanism 2 to move the plant along the predetermined path. When it passes the epidermal cutting mechanism 3, the rotating frame 31 rotates and drives the cutter 32 to perform arc-shaped cutting on one surface of the plant stem to complete the single-sided epidermal cleaning.

[0050] S4. The plant stem sequentially passes through the first processing component 11, the second processing component 12, the third processing component 13, and the fourth processing component 14. Each component is responsible for cleaning a different surface, thus completing a comprehensive epidermal cleaning. During the transition between adjacent surfaces, the discharge component 25 supports the stem at the discharge end of the preceding processing component 1, ensuring a smooth transition to the next processing component 1, ready for epidermal cleaning of the next surface. During the transition between opposite surfaces, the discharge component 25 restricts the movement of the stem at the discharge end of the preceding processing component 1, ensuring a smooth transition to the processing component 1 of the opposite surface. Since the processing of opposite surfaces does not require an additional feeding component 24 to fix the stem, epidermal cleaning can be performed directly, simplifying the operation process.

[0051] S5. When the plant stem reaches the discharge part 25 of the fourth processing part 14, the movement of the plant is restricted by the discharge part 25, so that the fixing part 21 is separated from the plant, and the pineapple plant stem is collected after the skin cleaning is completed.

[0052] Furthermore, as is common knowledge in this industry, the conveying mechanism 2 and the surface cutting mechanism 3 in the first processing component 11, the second processing component 12, the third processing component 13, and the fourth processing component 14 mentioned above are all equipped with independent drive motors, linear transmission components frame 51 and template 52. Since this is common knowledge, their principles and structures will not be elaborated upon further.

[0053] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
