Description

Technical Field

[0001] This invention belongs to the technical field of high-efficiency cutting equipment, specifically relating to a high-efficiency cutting device for bamboo leaf powder production. Background Technology

[0002] Bamboo leaf powder is rich in bamboo leaf flavonoids, a highly effective biological antioxidant belonging to structurally stable carbon glycoside flavonoids. It exhibits outstanding performance in anti-oxidation and blood lipid regulation. In addition, bamboo leaf powder also contains phenolic acids, polysaccharides, dietary fiber, and various trace elements such as potassium, calcium, and magnesium. Therefore, as a pure natural, additive-free green raw material, bamboo leaf powder is becoming an innovative choice for the food industry. With its emerald green color and refreshing aroma, bamboo leaf powder is widely used in the production of bamboo powder, baked goods, tea drinks, ice cream, noodles, and other foods. In short, processed bamboo leaf powder is suitable for the fields of traditional Chinese medicine, food additives, and feed processing. Cutting bamboo leaves using cutting equipment is a crucial pre-processing step in bamboo leaf powder processing. Because fresh or rehydrated bamboo leaves have a large surface area and high moisture content, cutting them into smaller segments or fragments significantly increases the surface area, allowing for easier moisture evaporation. This drastically shortens drying time, improves production efficiency, and saves energy. Furthermore, bamboo leaves are rich in coarse fibers and have considerable toughness. If not cut before crushing, the long fibers easily entangle the crusher blades or clog the screen. Pre-cutting makes the material shorter and more uniform, allowing the crusher to grind it into finer powder more efficiently. While existing cutting equipment can cut roots and stems, it struggles to efficiently and specifically cut bamboo leaves into small fragments during the cutting process.

[0003] A Chinese patent document with publication number CN217256527U discloses a cutting device for Chinese medicinal leaves. The device feeds leaves onto a tray through a feed pipe, and then cuts the leaves using a blade structure. The rotation of the blades improves the cutting effect. After cutting, the tray leaves the positioning barrel, and a pusher plate pushes the leaves off the push plate, achieving the effect of feeding and cutting simultaneously. However, in the above method, the blade structure cuts the leaves first and then rotates to cut. When using the above cutting device to cut bamboo leaves, after the blade falls and cuts the long bamboo leaves into several segments, these short bamboo leaves still have a large surface area and toughness. When the blade rotates again to further chop them, the centrifugal force and airflow of the rotation can easily cause these thin and soft leaves to become entangled in the blade shaft or the root of the blade, causing the equipment to stop or even be damaged.

[0004] Therefore, this invention proposes a high-efficiency cutting device for bamboo leaf powder production, solving the problem in existing technologies where thin and soft leaves easily become entangled in the blade shaft or blade root due to the first cutting followed by rotational cutting. The invention improves the cutting tool structure by using a composite blade structure with a rotating outer ring and a fixed inner ring. The inner ring blade is stationary, and when the outer ring rotating blade passes by, a narrow shearing gap is formed between them. Any leaves attempting to entangle in the inner ring or shaft are blocked and cut by the fixed blade's cutting edge, effectively achieving dynamic self-cleaning. Even if a small amount of fiber gets entangled, it will be scraped and cut off by the inner ring fixed blade in the next rotation cycle, fundamentally eliminating jamming caused by fiber accumulation. Furthermore, a lower-layer shearing tool structure is designed, using airflow to blow incompletely cut bamboo leaves into the lower layer for secondary shearing. Leaves that have just been cut but have not yet fallen are blown away from the blades to prevent adhesion. The airflow then carries the leaves into the lower shearing zone, where the airflow can blow and agitate lightweight bamboo leaf fragments, causing them to pass through the blade gap multiple times for efficient cutting.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1 to 7This invention provides a technical solution: a high-efficiency cutting device for bamboo leaf powder production, comprising a cutting device body 1, a feeding hopper 11 fixedly installed above the cutting device body 1, a discharging hopper 12 fixedly installed below the cutting device body 1, a tower-shaped protective cover 3 disposed inside the cutting device body 1, the lower surface of the tower-shaped protective cover 3 being fixedly connected to the upper surface of the discharging hopper 12, a cutting seat 4 fixedly installed on the upper surface of the tower-shaped protective cover 3, and a rotating cutting seat 5 rotatably installed inside the cutting seat 4; a toothed ring is fixedly installed on the outer surface of the rotating cutting seat 5, and the inner surface of the cutting seat 4... A gear assembly driving the aforementioned gear ring to rotate is provided on one side of the cutting equipment. Bamboo leaves enter the upper part of the cutting equipment body 1 from the feed bin 11. The tower-shaped protective cover 3 is located inside the cutting equipment body 1 and the discharge bin 12, mainly serving to install the cutting seat 4. The rotating cutting seat 5 is rotatably installed inside the cutting seat 4 and can rotate through the gear ring driven by the gear assembly. The rotating cutting seat 5 has a hollow cover structure. A fixing tube 6 is provided inside the rotating cutting seat 5. The lower outer surface of the fixing tube 6 is fixedly connected to the bottom inner wall of the cutting seat 4, and a fixing cutter is fixedly installed on the upper outer surface of the fixing tube 6. The cutting table 61 is fixed, with its outer surface rotatably connected to the upper inner surface of the rotary cutting seat 5. Three sets of cutting blades 62 are fixedly mounted on the upper surface of the fixed cutting table 61, all installed at an angle along their radial direction. T-shaped air vents 52 are evenly distributed on the sidewall of the rotary cutting seat 5. A guide plate 51 is movably mounted on the inner side of the rotary cutting seat 5. A telescopic connecting rod 53 is hinged to the upper inner surface of the rotary cutting seat 5, with its upper end rotating with the inner wall of the guide plate 51. The guide plate 51 and telescopic connecting rod 53 are evenly distributed in six sets. An extrusion boss 511 is fixedly installed in the middle of the outer side wall of the guide plate 51. A material distribution groove 512 is opened in the middle of the guide plate 51. A shearing bend 513 is fixedly installed on the lower surface of the guide plate 51. A cutting blade 514 is fixedly installed on the upper surface of the rotary cutting seat 5 near the cutting blade 62. The cutting blade 514 is installed at an angle along the tangent direction of the fixed cutting table 61. The installation height of the highest point of the inclination of the cutting blade 62 is higher than the installation height of the highest point of the inclination of the cutting blade 514. In this embodiment, the rotary cutting seat 5 mainly serves to install the guide plate 51 and drive the six sets of guide plates 51 to rotate. The guide plate 51 mainly serves to install the first cutting blade 514 and the shearing curved blade 513. Together with the second cutting blade 62 installed on the fixed cutting table 61, it forms a composite cutting tool with an outer rotating layer and an inner fixed layer. As the rotary cutting seat 5 rotates, a narrow shearing gap is formed between the first cutting blade 514 and the second cutting blade 62. The blades wrapped around the first cutting blade 514 will be blocked and cut by the cutting edge of the second cutting blade 62, which is equivalent to dynamic self-cleaning. Even if a small amount of fiber gets tangled, it will be scraped off and cut off by the second cutting blade 62 in the next rotation cycle, which fundamentally eliminates the jamming caused by fiber accumulation and achieves efficient cutting of bamboo leaves.

[0021] Example 2 Please see Figures 8 to 11 Based on Embodiment 1, to achieve more uniform bamboo leaf cutting, this embodiment further proposes that an air chamber 41 be fixedly installed above the cutting seat 4. The top inner wall of the air chamber 41 has evenly spaced air outlet slots 411. A fixed shearing blade 43 is fixedly installed on the upper surface of the air chamber 41. A movable shearing blade 431 is hinged to the side of the fixed shearing blade 43 near the rotating cutting seat 5. The cutting slit between the fixed shearing blade 43 and the movable shearing blade 431 is inclined, matching the cutting direction of the shearing curved blade 513. A central connecting pipe 42 is provided below the cutting seat 4. The top inner wall of the central connecting pipe 42 is fixedly connected to the bottom of the fixed pipe 6. Exhaust grooves 63 are evenly spaced above the side wall of the fixed pipe 6. A wind chamber connecting pipe 421 is fixedly installed on the side wall of 2. The upper end of the wind chamber connecting pipe 421 passes through the bottom of the wind chamber 41. Fan 1 31 and Fan 2 32 are symmetrically arranged inside the lower part of the tower-shaped protective cover 3. An air inlet hood is set in the middle of the bottom inner wall of the feed hopper 11. An discharge hopper door is set on the side wall of the discharge hopper 12. An annular air inlet pipe 321 is fixedly installed in the middle of the inner side of the tower-shaped protective cover 3. A central air inlet pipe 311 is fixedly installed on the inner surface of the annular air inlet pipe 321. The bottom pipe of the annular air inlet pipe 321 is fixedly connected to the air outlet pipe of Fan 2 32. The bottom pipe of the central air inlet pipe 311 is fixedly connected to the air outlet pipe of Fan 1 31. The top pipe of the central air inlet pipe 311 is fixedly connected to the bottom inner wall of the central connecting pipe 42. In this embodiment, the tower-shaped protective cover 3 also serves to separate the internal space of the discharge hopper 12, separating the blower 31 and blower 32 from the discharge area. The blower 31 mainly supplies air to the central connecting pipe 42 through the central air inlet pipe 311. The central connecting pipe 42 serves as the central hub pipe, with its upper end connected to the fixed pipe 6. In addition to installing the fixed cutting table 61, the fixed pipe 6 also outputs air to the rotary cutting seat 5 through the exhaust groove 63. The T-shaped exhaust groove 52 serves not only as a through groove for installing the guide plate 51, but also as a ventilation groove for exhausting air to the upper surface of the guide plate 51. When the rotary cutting seat 5 rotates, the guide plate 51, due to centrifugal force, will spread outward in a petal-like shape with the cooperation of the telescopic connecting rod 53, exposing the T-shaped exhaust groove 52 for exhaust. At this time, the airflow can blow the bamboo leaves cut by the first cutting blade 514 and the second cutting blade 62. The guide plate 51 also plays a guiding role. Small fragments will be blown away directly along the surface of the guide plate 51, while larger fragments will enter the lower shearing area through the material distribution groove 512. At this time, the rotation of the guide plate 51 drives the shearing curved blade 513 to continuously pass through the gap between the fixed shearing blade 43 and the movable shearing blade 431. At the same time, the air cavity connecting pipe 421 on the side of the central connecting pipe 42 delivers air into the air cavity chamber 41 and discharges it through the air outlet slit groove 411. The airflow can blow up and turn the light bamboo leaf fragments, so that they are driven by the shearing curved blade 513 and pass through the movable shearing blade 431 and the fixed shearing blade 43 multiple times for secondary efficient cutting.

[0022] Example 3 Please see Figures 5 to 6 Based on Embodiment 2, in order to facilitate the smooth discharge of the cut fragments, this embodiment further proposes that an auxiliary air duct 33 be provided inside the upper part of the tower-shaped protective cover 3, a central pipe 333 be fixedly installed inside the auxiliary air duct 33, a side branch pipe 3211 be fixedly installed on the top inner wall of the annular air inlet pipe 321, the upper end of the side branch pipe 3211 penetrates the upper side wall of the central pipe 333, side air outlets 331 are evenly distributed on the side wall of the auxiliary air duct 33, the side air outlets 331 are spirally distributed, and a spiral guide vane 332 is fixedly installed on the inner surface of the auxiliary air duct 33. In this embodiment, the second fan 32 mainly supplies air to the auxiliary air duct 33 formed between the central pipe 333 and the tower-shaped protective cover 3 through the annular air inlet pipe 321 and the side branch pipe 3211. The airflow is spirally guided by the spiral guide vanes 332 arranged inside the auxiliary air duct 33 and discharged obliquely downward along the side wall of the tower-shaped protective cover 3 through the side air outlet 331. This plays a certain guiding role for the bamboo leaf fragments discharged from above, so that the fragments are smoothly carried by the airflow and fall into the area of ​​the discharge bin 12. The cut bamboo leaf fragments can be taken out by opening the discharge bin door of the discharge bin 12.

[0023] Example 4 Please see Figures 3 to 4 Based on Embodiment 3, in order to allow the cut fragments to be smoothly discharged through the outside of the cutting seat 4, this embodiment also proposes that a guide hopper 23 is fixedly installed at the lower end of the feeding hopper 11, a micro-movement diaphragm 21 is fixedly installed on the outside of the guide hopper 23, a micro-movement air chamber 2 corresponding to the position of the micro-movement diaphragm 21 is provided inside the upper part of the cutting equipment body 1, micro-movement air holes 22 are evenly distributed on the middle side wall of the micro-movement diaphragm 21, the inner surface of the micro-movement diaphragm 21 is in contact with the outer surface of the extrusion boss 511, and an air pump 24 is provided on the outside of the cutting equipment body 1, and the air pump 24's air pump pipe penetrates the inner wall of the side branch pipe of the cutting equipment body 1. In this embodiment, the micro-movement air chamber 2 serves as an air chamber. The air pump 24 pumps gas into the micro-movement diaphragm 21, maintaining a certain air pressure inside the micro-movement air chamber 2. As the rotating cutting seat 5 drives the guide plate 51 to rotate, the extrusion boss 511 extrudes the inside of the micro-movement diaphragm 21. The guide hopper 23 guides the blades to enter the cutting blade 1 514 and the cutting blade 2 62 for cutting. At this time, due to the different cutting resistance on different guide plates 51 and the cooperation of centrifugal force, the extrusion boss 511 extrudes the micro-movement diaphragm 21 to different degrees. Each extrusion of the micro-movement diaphragm 21 will locally compress the volume of the micro-movement air chamber 2, increasing the air pressure. The micro-movement air hole 22 ejects airflow. When the guide plate 51 leaves, the wall of the micro-movement diaphragm 21 in that area elastically recovers, and the air pressure decreases, forming a "breathing pump" effect, allowing the cut fragments to be discharged smoothly and avoiding blockage on the outside of the cutting seat 4.

[0024] Example 5 Please see Figures 1 to 12 Based on Example 4, this example also proposes a method for using a high-efficiency cutting device for bamboo leaf powder production, including the following steps: Step 1: Bamboo leaves are fed into the feed hopper 11. The guide hopper 23 guides the leaves to enter the cutting blade 514 and the cutting blade 62 for cutting. As the rotating cutting seat 5 rotates, a narrow shearing gap is formed between the cutting blade 514 and the cutting blade 62. The leaves are blocked and cut by the cutting edges of the cutting blade 62 and the cutting blade 514. Step two: Fan 31 supplies air to the central connecting pipe 42 through the central air inlet pipe 311. The upper end of the central connecting pipe 42 is connected to the fixed pipe 6. Air is output to the rotary cutting seat 5 through the exhaust duct 63. The T-shaped exhaust duct 52 also serves to exhaust air to the upper surface of the guide plate 51. When the rotary cutting seat 5 rotates, the guide plate 51, due to centrifugal force, will spread outward in a petal shape with the cooperation of the telescopic connecting rod 53, exposing the T-shaped exhaust duct 52 for exhaust. At this time, the airflow can blow away the bamboo leaves cut by the first cutting blade 514 and the second cutting blade 62, breaking up small fragments. The fragments will be blown away directly along the surface of the guide plate 51, while larger fragments will enter the lower shearing area through the material distribution groove 512. At this time, the guide plate 51 rotates, causing the shearing curved blade 513 to continuously pass through the gap between the fixed shearing blade 43 and the movable shearing blade 431. At the same time, the air cavity connecting pipe 421 on the side of the central connecting pipe 42 supplies air into the air cavity chamber 41 and discharges it through the air outlet slit groove 411. The airflow can blow up and turn the lightweight bamboo leaf fragments, causing them to pass through the movable shearing blade 431 and the fixed shearing blade 43 multiple times with the shearing curved blade 513, and perform secondary efficient cutting. Step 3: As the rotating cutting seat 5 drives the guide plate 51 to rotate, the extrusion boss 511 will extrude pressure on the inside of the micro-moving diaphragm 21. The cutting resistance on different guide plates 51 is different, and with the cooperation of centrifugal force, the degree of extrusion on the micro-moving diaphragm 21 by different extrusion bosses 511 is different. Each extrusion will locally compress the volume of the micro-moving air chamber 2, the air pressure will increase, and the air will be ejected from the micro-moving air hole 22. When the guide plate 51 leaves, the wall of the micro-moving diaphragm 21 in this area will elastically recover, the air pressure will decrease, forming a "breathing pump" effect, so that the cut fragments can be discharged smoothly and avoid being blocked on the outside of the cutting seat 4. Step four: Fan 2 32 delivers air to the auxiliary air duct 33 formed between the central pipe 333 and the tower-shaped protective cover 3 through the annular air inlet pipe 321 and the side branch pipe 3211. The airflow is spirally guided by the spiral guide vanes 332 arranged inside the auxiliary air duct 33 and discharged obliquely downward along the side wall of the tower-shaped protective cover 3 through the side air outlet 331. This guides the bamboo leaf fragments that fall from above, allowing the fragments to be carried by the airflow and fall smoothly into the discharge bin 12 area. The discharge bin door of the discharge bin 12 can be opened to remove the cut bamboo leaf fragments.
