Description

Technical Field

[0001] The invention belongs to the technical field of peeling machines, and in particular relates to a pineapple plant stem epidermis cleaning device and a use method thereof. Background Art

[0002] Pineapple fiber has become an ideal alternative material in the fields of textiles and composite materials due to its high strength, low density, good moisture absorption and biodegradability. The main fiber used in the market is from pineapple leaves, because leaf fibers are relatively easy to obtain. In contrast, pineapple stem fibers have a harder structure and high content of lignin and other binding substances, which limits their widespread application. Therefore, the main challenges faced in improving the utilization of pineapple stem fibers include:

[0003] First, most existing fiber extraction equipment is designed to process softer plant materials, such as pineapple leaves or cotton. For pineapple stems, which are harder and often cling to dirt, dust and other impurities, traditional equipment may not be able to effectively process them, resulting in low fiber extraction efficiency.

[0004] Secondly, the skin of the pineapple stem contains harder fibers, while the fibers inside are softer and suitable for extraction. Therefore, when processing the pineapple stem, it is usually necessary to remove the skin first to facilitate further processing. However, due to the significant differences in the size and morphology of pineapple plants, this diversity further increases the difficulty of stem fiber processing. Summary of the invention

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

[0011] Furthermore, to ensure the loading of plant stems of different specifications: the feeding piece located on the feeding end of the first processing component is set on a spring lifting frame; the spring lifting frame allows the feeding piece on the feeding end of the first processing component to be adjusted in position to facilitate the cleaning of the epidermis of plant stems of different specifications.

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

In addition, in this specific implementation method, if the connection or fixing method between the components is not particularly specified, the connection or fixing method can be fixed by bolts or pins commonly used in the prior art, or by pin connection, etc., and therefore, it will not be described in detail in this embodiment.

[0034] Embodiment 1

[0035] See also Figure 1 The present embodiment discloses a pineapple plant stem epidermis cleaning device, the epidermis cleaning device is composed of a processing component 1, the processing component 1 is composed of 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, the fixing members 21 are used for placing and fixing the plant stem; the epidermis cutting mechanism 3 is used for cleaning the single-sided epidermis of the plant stem; when the fixing members 21 complete the fixation of the plant stem, the plant stem is transported by the conveying mechanism 2, and the stem epidermis is cleaned when passing through the epidermis cutting mechanism 3, thereby completing the single-sided epidermis cleaning of the plant stem.

[0036] See also Figure 2In order to achieve comprehensive epidermal cleaning of the pineapple stem, additional processing components 1 (second, third and fourth processing components 14) are added in this embodiment, each of which is responsible for cleaning a different surface. These components are arranged around the conveying path to form a closed-loop system, so that the epidermal cleaning of all four surfaces of the pineapple stem can be completed in one pass. The processing components 1 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 epidermal cleaning of different surfaces of the plant stem, so as to complete the comprehensive epidermal cleaning of the plant stem.

[0037] See also Figure 3 , Figure 4 The conveying mechanism 2 includes a transmission gear 22, on which a transmission chain 23 is arranged, and the fixing member 21 is a spike and is fixedly arranged 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 the processing; the precise meshing of the gears ensures the stable operation of the chain, avoids the occurrence of sliding or jumping, and makes 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 can be properly fixed. The fixing member 21 is inserted into the stem of the plant to achieve the placement and fixation of the plant stem. The fixing member 21 adopts a spike design and can be directly inserted into the pineapple stem, providing a very firm fixing point; at the same time, the hardness and shape of the pineapple stem are also taken into consideration, which can effectively prevent displacement or rotation during the cutting process.

[0038] The setting of the feed piece 24 and the discharge piece 25 is introduced: the feed piece 24 is used to limit the movement of the plant stem, ensuring that the fixing piece 21 (spike) can be accurately inserted into and fixed on the plant stem; the discharge piece 25 is used to limit the movement of the plant stem, ensuring that the fixing piece 21 (spike) can be safely separated from the plant stem. The design of the feed piece 24 and the discharge piece 25 effectively limits the movement of the plant stem during the processing, ensuring that the fixing piece 21 (spike) can be accurately inserted and separated, and improving the stability and reliability of the entire system; through precise clamping and fixing, the accuracy of the cutting process is ensured, and the risk of uneven cutting or damage to internal fibers caused by the movement of the stem is reduced. The accuracy of the cutting process is ensured, and the risk of uneven cutting or damage to internal fibers caused by the movement of the stem is reduced.

[0039] The processing component 1 is provided with a feed piece 24 and a discharge piece 25 for limiting the movement of the plant stem, the feed piece 24 is used to limit the movement of the plant stem so that the fixing piece 21 can fix the plant stem; the discharge piece 25 is used to limit the movement of the plant stem so that the fixing piece 21 can be separated from the plant stem; the feed piece 24 is arranged near the feed end of the first processing component 11 and is located on one side of the epidermis cutting mechanism 3 in the first processing component 11; the discharge piece 25 is arranged near the discharge end of the fourth processing component 14 and is located on one side of the conveying mechanism 2 in the first processing component 11. The plant stem passes through the first processing component 11, the second processing component 12, the third processing component 13 and the fourth processing component 14 in sequence, and can be divided into adjacent surface processing transition and opposite surface processing transition according to the difference in the front and rear processing surfaces of the plant stem; during the adjacent surface processing transition, the feed piece 24 is also arranged at the feed end of the rear processing component 1 and is located on one side of the epidermis cutting mechanism 3 in the rear processing component 1, and the discharge piece 25 is also arranged at the discharge end of the front processing component 1 and is located on one side of the conveying mechanism 2 in the front processing component 1; during the opposite surface processing transition, the discharge piece 25 is also arranged at the discharge end of the front processing component 1 and is located on one side of the conveying mechanism 2 in the front processing component 1. At this time, the discharge piece 25 also plays the role of the feed piece 24 to provide support for the plant stem to enter the next processing component 1.

[0040] The feed piece 24 located on the feed end of the first processing component 11 is arranged on a spring lifting frame 26; the spring lifting frame 26 utilizes the elastic characteristics of the spring to automatically adjust the height of the feed piece 24 according to the diameter of the plant stem. When a stem with a smaller diameter enters, the spring will naturally compress, causing the feed piece 24 to drop to an appropriate position; when a stem with a larger diameter enters, the spring will stretch, causing the feed piece 24 to rise to a higher position. The spring lifting frame 26 allows the feed piece 24 on the feed end of the first processing component 11 to be adjusted in position, so as to facilitate the cleaning of the epidermis of the plant stems of different specifications; the elastic force of the spring can be pre-set to ensure that the clamping force applied by the feed piece 24 on the plant stem is moderate, neither too tight to cause damage nor too loose to affect the fixing effect.

[0041] See also Figure 5The epidermis cutting mechanism 3 is composed of a rotating frame 31 and a cutter 32 arranged 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 arranged in the middle and at both ends, and the cutter 32 is evenly arranged on the surface of the rotating frame 31; ensuring that the epidermis of the pineapple stem can be effectively contacted during the entire rotation process. This arrangement can ensure that the epidermis of each part can be cleaned evenly without omission or excessive cleaning. When the rotating frame 31 rotates, it drives the cutter 32 to perform arc cutting on the epidermis of the plant stem; imitating the action of manual cutting, it can more naturally fit the curve of the pineapple stem, thereby achieving more uniform and smooth epidermis removal. At the same time, the arc cutting path helps to reduce potential damage to the internal fibers, because the cutter 32 contacts and removes the epidermis in a gentle manner, rather than cutting in at right angles or sharp angles, reducing the pulling or tearing of the fibers.

[0042] See also Figure 6 The processing part 1 is provided with a tensioning mechanism 4 for controlling the tension of the transmission chain 23. The tensioning mechanism 4 includes an adjusting member 41. The adjusting member 41 is provided with a rotating member 42 in contact with the transmission chain 23. The function of the rotating member 42 is to guide the movement of the transmission chain 23, reduce friction and prevent the chain from deflecting or getting stuck during operation. By controlling the position of the adjusting member 41, the tension of the transmission chain 23 can be controlled, and the tightness of the transmission chain 23 can be changed to ensure that it always maintains appropriate tension. The adjusting member 41 is set on the shock absorbing rod 43, and the shock absorbing rod 43 is used to prevent the transmission chain 23 from falling off when the epidermis of the plant stem is cleaned. The main function of the shock absorbing rod 43 is to absorb the vibration and impact generated by the transmission chain 23 during operation, so as to prevent the chain from falling off or being damaged due to excessive vibration. The shock absorbing rod 43 is usually equipped with a spring or other elastic element, which can buffer external forces to a certain extent and maintain the stability of the system.

[0043] See also Figure 7, the adjusting member 41 is located inside the transmission chain 23, and the adjusting members 41 are respectively the first adjusting member 411 and the second adjusting member 412. The first adjusting member 411 and the second adjusting member 412 act on the transmission chain on both sides respectively. The first adjusting member 411, the second adjusting member 412 and the epidermis cutting mechanism 3 belong to the same straight line, and the straight line is parallel to the conveying direction of the conveying mechanism 2; the double-sided adjustment design ensures that the transmission chain 23 always maintains balance during operation, avoiding the situation of being too loose or too tight after adjustment. The first adjusting member 411 and the second adjusting member 412 are both arranged at one end of the shock absorbing rod 43, and the other end of the shock absorbing rod 43 is provided with a control member 44; the first adjusting member 411 is close to the epidermis cutting mechanism 3, and the control member 44 controls the spacing between the first adjusting member 411 and the epidermis cutting mechanism 3 to achieve the control of the epidermis cutting amount of the plant stem. Combined with sensors and control systems, the spacing can be automatically adjusted according to pineapple stems of different diameters and shapes to ensure that each cutting can achieve the best effect. For example, for thicker stems, the spacing can be appropriately increased to reduce the amount of cutting; for thinner stems, the spacing can be reduced to increase the amount of cutting.

[0044] See also Figure 8 The surface cleaning equipment is also provided with a frame 5 for installing the processing component 1, and the frame 5 is composed of a frame 51 and a plate 52; the frame 51 is the main supporting structure of the entire equipment, providing mechanical strength and stability. It is usually made of high-strength steel or aluminum alloy, which ensures the durability of the equipment during long-term operation. The plate 52 is fixed on the frame 51 and is used to install the conveying mechanism 2 and the surface cutting mechanism 3. The design of the plate 52 takes into account flatness and rigidity, ensuring the precise installation and stable operation of each component. The combined design of the frame 51 and the plate 52 makes the equipment modular and easy to assemble, disassemble and maintain. At the same time, this design can flexibly adjust the position of each component according to actual needs, thereby improving the versatility and adaptability of the equipment. The conveying mechanism 2 and the skin cutting mechanism 3 are both arranged on the mold plate 52, the tensioning mechanism 4 is arranged on the mold frame 51, and the linear transmission component is arranged between the tensioning mechanism 4 and the mold frame 51, and the linear transmission component is used to control the position of the control member 44; so that the tensioning mechanism 4 can be adjusted independently of other components, avoiding the vibration of the conveying mechanism 2 or the skin cutting mechanism 3 affecting the operation of the tensioning mechanism 4; the linear transmission component is used to control the position of the member 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 push rods, etc., and the specific selection depends on the needs and application scenarios of the equipment.

[0045] Embodiment 2

[0046] This embodiment discloses a method for using a pineapple plant stem epidermis cleaning device, using the epidermis cleaning device described in Embodiment 1, and the method comprises:

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

[0048] S2, placing the stem of the pineapple plant in the fixing member 21 on the conveying mechanism 2, and fixing 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 a predetermined path. When the plant passes through the epidermis cutting mechanism 3, the rotating frame 31 rotates to drive the cutter 32 to perform arc cutting on one surface of the plant stem to complete the single-side epidermis cleaning;

[0050] S4. The stem of the plant passes through the first processing part 11, the second processing part 12, the third processing part 13 and the fourth processing part 14 in sequence, and each part is responsible for cleaning a different surface, thereby completing comprehensive epidermis cleaning; when the adjacent surfaces are processed in transition, the discharge piece 25 supports the stem at the discharge end of the front processing part 1 to ensure that it smoothly transitions to the next processing part 1, preparing for the next surface epidermis cleaning. When the opposite surface is processed in transition, the discharge piece 25 limits the movement of the stem at the discharge end of the front processing part 1 to ensure that it smoothly transitions to the processing part 1 of the opposite surface. Since the opposite surface processing does not require an additional feed piece 24 to fix the stem, the epidermis cleaning can be performed directly, simplifying the operation process.

[0051] S5. When the stem of the plant reaches the discharging piece 25 of the fourth processing component 14, the discharging piece 25 restricts the movement of the plant, so that the fixing piece 21 is separated from the plant, and the collection of the pineapple plant stem with the skin cleaned is completed.

[0052] In addition, as common knowledge in the industry, the conveying mechanism 2 and the skin 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 driving motors, linear transmission component jigs 51 and jigs 52. The above is common knowledge, so its principle and structure will not be described in detail.

[0053] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
