Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry product processing technology, and in particular to a small-diameter bamboo shoot peeling equipment with cutting feedback downward pressure. Background Technology

[0002] Southern my country is rich in various types of bamboo, and its tender shoots, known as bamboo shoots, are highly sought-after specialty agricultural products due to their crisp and tender texture and rich nutritional content, including dietary fiber. Small-diameter bamboo shoots are widely distributed in the Jiangsu and Zhejiang areas. These shoots are generally slender and conical in shape, relatively small in size, and have a loosely woven husk. In terms of size, their base diameter is typically between 10 and 25 mm, and their length is approximately 250 to 400 mm. About two-thirds of the shoot is edible, so about one-third of the non-edible portion at the tip needs to be removed. The outer husk is approximately 1 to 3 mm thick.

[0003] The first step in the initial processing of bamboo shoots is peeling off the outer husk. Because fresh bamboo shoots lose moisture quickly after breaking through the soil, the husk must be removed promptly to maintain quality. However, currently, peeling small-diameter bamboo shoots still heavily relies on manual labor. This manual operation is time-consuming, labor-intensive, and inefficient, making it difficult to meet the demands of large-scale production and rapid preservation. Summary of the Invention

[0004] The purpose of this invention is to provide a small-diameter bamboo shoot peeling equipment with cutting feedback downward pressure that can efficiently complete the peeling operation of small-diameter bamboo shoots, effectively reduce the conveying resistance in the non-cutting state, control the damage rate at a low level, meet food processing requirements, and save labor costs.

[0005] To solve the above-mentioned technical problems, the present invention provides a small-diameter bamboo shoot peeling equipment with cutting feedback pressing action, including a frame, a conveyor belt rotatably disposed on the frame, a positioning mechanism, a pressing mechanism, and a cutting mechanism connected to the frame and sequentially located above the conveyor belt, so that the bamboo shoot passes along the conveyor belt sequentially through the centering guidance of the positioning mechanism, the pressing and positioning of the pressing mechanism, and the cutting and peeling of the bamboo shoot; the cutting mechanism includes mounting plates connected to both sides of the frame, a lifting platform vertically disposed between the mounting plates, and a blade rotatably connected to the lifting platform, with limit plates symmetrically arranged on both sides of the blade, and the diameter of the limit plates is smaller than the diameter of the blade, so that the limit plates abut against the outer surface of the bamboo shoot during the cutting process.

[0006] Furthermore, a guide plate is connected between the mounting plates on both sides, and several guide components are axially movable and installed on the guide plate. The ends of the several guide components are connected to the lifting platform. The lifting platform is rotatably connected to a blade shaft, and the blade and the limiting plate are sequentially sleeved along the blade shaft axis.

[0007] Furthermore, the pressing mechanism includes limiting plates connected to both sides of the frame, a roller shaft movably connected between the limiting plates, and a saddle-shaped roller rotatably sleeved on the roller shaft. The limiting plates have limiting grooves, the end of the roller shaft is movably installed in the limiting groove, and the roller shaft is perpendicular to the surface of the conveyor belt along the moving direction of the limiting groove.

[0008] Furthermore, a connecting rod shaft is connected between the two mounting plates, and an adjusting connecting rod is rotatably connected to the connecting rod shaft. An adjusting seat is provided at the lifting platform. One end of the adjusting connecting rod is hinged to the adjusting seat through a first connecting rod, and the other end is hinged to the connecting shaft. The two ends of the connecting shaft are respectively hinged to the two ends of the roller shaft through a second connecting rod.

[0009] Furthermore, the mounting plate has an adjustment groove on its side, and the end of the connecting rod shaft is movably mounted in the adjustment groove, with the connecting rod shaft perpendicular to the surface of the conveyor belt along the moving direction of the adjustment groove.

[0010] Furthermore, the positioning mechanism includes positioning plates connected to both sides of the frame and guide ramps inclined at the ends of the positioning plates, so that the bamboo shoots enter between the two positioning plates along the guide ramps, and a number of positioning wheels are sequentially arranged at the positioning plates along the conveying direction of the conveyor belt.

[0011] Furthermore, it also includes a peeling mechanism mounted on the frame and located at the discharge end of the conveyor belt. The peeling mechanism includes a first roller rotatably connected to the frame and a second roller rotatably connected to the frame and meshing with the first roller. Friction rollers are fitted on both the first and second rollers so that the bamboo shoot shells pass between adjacent friction rollers. A second drive wheel is rotatably mounted on the frame. A second synchronous wheel is mounted at the end of the first or second roller. A second tensioning rod is movably connected to the frame. A second tensioning wheel is rotatably mounted on the second tensioning rod so that the second synchronous wheel, the second tensioning wheel, and the second drive wheel are connected by a second synchronous belt drive.

[0012] Furthermore, a first conveyor roller and a second conveyor roller are rotatably mounted on the frame, and a conveyor belt is sleeved on the outer periphery of the first conveyor roller and the second conveyor roller. A first drive wheel is rotatably mounted on the frame, a first synchronous pulley is provided at the end of the first conveyor roller, and a first tensioning rod is movably connected to the frame. A first tensioning wheel is rotatably mounted on the first tensioning rod, so that the first synchronous pulley, the first tensioning wheel and the first drive wheel are connected by a first synchronous belt drive.

[0013] Furthermore, a tensioning groove is provided on the side of the frame, and a tensioning shaft is rotatably connected to the end of the second conveying roller. The tensioning shaft is also movable in the tensioning groove so that the second conveying roller moves along the tensioning groove to adjust the tension of the conveyor belt.

[0014] Furthermore, the lifting platform is connected to a drive unit on its side, the end of the blade shaft is connected to the output end of the drive unit, and at least two fixed seats are arranged opposite each other on the lifting platform. The blade shaft passes through the fixed seats and rotates with the fixed seats. At least two fixed rings are arranged axially on the blade shaft, and the blade and the limiting plate are located between the two fixed rings. The lifting platform has a counterweight on its side, so that the counterweight and the drive unit are placed on opposite sides of the lifting platform.

[0015] The beneficial effects of this invention are as follows: 1. It can efficiently and automatically peel small-diameter bamboo shoots, achieving the removal of bamboo shoot shells and reducing manual labor costs; 2. The cutting mechanism achieves initial centering of bamboo shoots with low resistance through positioning plates and positioning wheels; and through the linkage mechanism of the first link, the second link and the adjusting link, the lifting displacement of the blade is converted into the vertical downward pressure of the saddle-shaped roller, and the lifting amount of the blade is almost the same as the downward pressure of the roller, so that the clamping is only applied during cutting, which greatly reduces the conveying resistance. Furthermore, the wrapping positioning of the saddle-shaped roller avoids deviation during cutting. 3. The cutting mechanism controls the lifting platform through the guide components, enabling the blade to float up and down for cutting. Limiting discs are set on both sides of the blade to achieve a fixed depth of cutting, thus cutting through the bamboo shoot shell without damaging the internal bamboo shoot flesh. Furthermore, the blade rotates along the bamboo shoot conveying direction, greatly reducing cutting resistance. 4. The peeling mechanism generates symmetrical downward friction through the opposite rotation of two rollers, which makes the bamboo shoot shell dragging smoothly. In addition, the surface of the friction rollers is covered with anti-slip material, and the gap between the two rollers is adjustable, which facilitates the optimization of the prototype. 5. The installation positions of each mechanism on the frame, the blade height in the cutting mechanism, and the relative position of the friction roller and the frame in the peeling mechanism can all be adjusted according to the actual diameter of different bamboo shoots on the conveyor belt to adapt to the processing of bamboo shoots of different diameters.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, 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. Therefore, the above terms should not be construed as limiting this invention.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] like Figure 1 , Figure 2As shown, the present invention provides a small-diameter bamboo shoot peeling equipment with cutting feedback pressing action, including a frame 1, a conveyor belt 2 rotatably set at the frame 1, a positioning mechanism 3 connected to the frame 1 and sequentially located above the conveyor belt 2, a pressing mechanism 4 and a cutting mechanism 5, so that the bamboo shoot 6 passes along the conveyor belt 2 sequentially through the centering guidance of the positioning mechanism 3, the pressing and positioning of the pressing mechanism 4, and the cutting and peeling of the cutting mechanism 5.

[0027] A first conveyor roller 21 and a second conveyor roller 22 are rotatably mounted on the frame 1. A conveyor belt 2 is sleeved around the outer periphery of the first conveyor roller 21 and the second conveyor roller 22. A first drive wheel 23 is rotatably mounted on the frame 1. A first synchronous wheel 24 is provided at the end of the first conveyor roller 21. A first tensioning rod 25 is movably connected to the frame 1. A first tensioning wheel 26 is rotatably mounted on the first tensioning rod 25, so that the first synchronous wheel 24, the first tensioning wheel 26 and the first drive wheel 23 are connected by a first synchronous belt 27.

[0028] Specifically, a motor drive unit is installed on the frame. The output shaft of the motor drive unit is fixedly connected to the first drive wheel 23 to drive the first synchronous belt to rotate, which in turn drives the first conveyor roller 21 to rotate through the first synchronous wheel 24, so as to realize the continuous operation of the conveyor belt 2. The first tension rod 25 is used to adjust the position of the first tension wheel, thereby adjusting the tension of the first synchronous belt 27. The first conveyor roller and the second conveyor roller are both connected to the frame through round flange bearings.

[0029] In one embodiment of this solution, the frame has a fixing plate with a threaded tightening bolt connected to it. The end of the tightening bolt tightens the first tensioning rod. The frame has a slot for the first tensioning rod to move. A spring is provided between the side of the first tensioning rod away from the tightening bolt and the slot, so that the position of the first tensioning wheel can be adjusted by the tightening bolt, thereby achieving fine adjustment of the tension of the first synchronous belt.

[0030] The bottom of the frame is equipped with casters via a caster mounting plate for easy movement; the two frames are connected by a frame-to-frame connecting shaft to ensure the overall structural strength; the conveyor belt has a forward speed of 0.2~0.3m / s and its surface is made of high-friction rubber material to ensure sufficient propulsion for the bamboo shoots during operation.

[0031] The frame 1 has a tension groove 28 on one side, and a tension shaft 29 is rotatably connected to the end of the second conveyor roller 22. The tension shaft 29 is also movable in the tension groove 28 so that the second conveyor roller 22 moves along the tension groove 28 to adjust the tension of the conveyor belt 2.

[0032] Specifically, by moving the tensioning shaft along the tensioning groove, the position of the second conveyor roller can be adjusted, thereby adjusting the tension of the conveyor belt 2 and ensuring smooth operation of the conveyor belt.

[0033] In one embodiment of this solution, the frame has a fixed plate with a threaded top bolt connected to it. The tensioning shaft is tensioned by the end of the top bolt. The frame has a slot for the tensioning shaft to move. A spring is provided between the side of the tensioning shaft away from the top bolt and the slot, so that the position of the tensioning shaft can be adjusted by the top bolt, thereby achieving fine adjustment of the tension of the conveyor belt. An inner ring bearing is connected between the tensioning shaft and the end of the second conveyor roller.

[0034] like Figure 3 , Figure 4 As shown, the cutting mechanism 5 includes mounting plates 51 connected to both sides of the frame 1, a lifting platform 52 that is lifted and lowered between the mounting plates 51, and a blade 53 that is rotatably connected to the lifting platform 52. Limiting discs 54 are symmetrically arranged on both sides of the blade 53, and the diameter of the limiting discs 54 is smaller than the diameter of the blade 53, so that the limiting discs 54 abut against the outer surface of the bamboo shoot 6 during the cutting process.

[0035] Specifically, when the bamboo shoot passes through the blade, the limiting plate holds against the bamboo shoot shell, while the blade cuts into the shell. The limiting plate limits the cutting depth of the blade. At the same time, as the diameter of the bamboo shoot increases, the limiting plate drives the lifting platform to rise synchronously, so as to achieve a floating adaptation to the cutting effect, ensuring that the blade always cuts into the appropriate depth of the bamboo shoot shell and avoids damaging the internal bamboo shoot flesh.

[0036] In one embodiment of this solution, the diameter of the blade is 60mm and the diameter of the limiting disc is 54mm, so that the length of the extended blade is 3mm, and this height difference effectively limits the cutting depth.

[0037] A guide plate 55 is connected between the mounting plates 51 on both sides. Several guide members 56 are axially movable and installed on the guide plate 55. The ends of the several guide members 56 are connected to the lifting platform 52. The lifting platform 52 is rotatably connected to the blade shaft 57. The blade 53 and the limiting plate 54 are sequentially sleeved along the blade shaft 57.

[0038] Specifically, the axial movement of the guide plate and guide components allows the lifting platform to move smoothly up and down along the guide plate, thereby causing the blade and the limiting plate to float synchronously. At the same time, the blade shaft, blade, and limiting plate are centered to ensure stability during the cutting process.

[0039] The guide component is connected to the guide plate by a flanged linear bearing. Both ends of the flanged linear bearing are fixed with limit screws to prevent it from falling off, thereby reducing frictional resistance and ensuring smooth lifting of the lifting platform 52.

[0040] The lifting platform 52 is connected to a drive unit 515 on its side. The end of the blade shaft 57 is connected to the output end of the drive unit 515. At least two fixed seats 516 are arranged opposite each other on the lifting platform 52. The blade shaft 57 passes through the fixed seats 516 and rotates with the fixed seats 516. At least two fixed rings 517 are arranged axially on the blade shaft 57. The blade 53 and the limiting plate 54 are located between the two fixed rings 517. The lifting platform 52 has a counterweight 518 on its side so that the counterweight 518 and the drive unit 515 are placed on opposite sides of the lifting platform 52.

[0041] Specifically, the drive unit can adopt a motor structure. The motor output end is connected to the blade shaft through a coupling, which drives the blade shaft to rotate, thereby driving the blade and the limit plate to rotate synchronously. At the same time, the fixed seat provides stable support for the blade shaft, and the fixed ring axially limits the blade and the limit plate to prevent them from shifting during high-speed rotation. The counterweight is used to adjust the weight of the motor so that the lifting platform as a whole remains balanced.

[0042] The blade shaft is connected to the fixed seat via a diamond flange bearing, and the fixing ring can be locked to the blade shaft using a clamp structure, thereby axially positioning the blade and the limiting plate.

[0043] During actual debugging, if the cutting mechanism has insufficient downward pressure or the blade bounces during cutting, the weight of the counterweight can be increased or its position adjusted on the lifting platform to ensure the stability of the cutting depth. If the cutting mechanism has excessive downward pressure during cutting and damages the bamboo shoot, a tension spring can be installed between the lifting platform and the guide plate to reduce the downward pressure.

[0044] like Figure 3 As shown, the pressing mechanism 4 includes a limiting plate 41 connected to both sides of the frame 1, a roller shaft 42 movably connected between the limiting plates 41, and a saddle-shaped roller 43 rotatably sleeved on the roller shaft 42. The limiting plate 41 has a limiting groove 44, and the end of the roller shaft 42 is movably installed in the limiting groove 44. The roller shaft 42 is perpendicular to the surface of the conveyor belt 2 along the moving direction of the limiting groove 44.

[0045] Specifically, the movement of the guide groove causes the saddle-shaped roller to roll and press down on the surface of the bamboo shoot, achieving stable pressing of the bamboo shoot. At the same time, the stroke limitation of the guide groove ensures that the roller shaft remains horizontal during the up and down movement, avoiding uneven pressing force caused by skewness.

[0046] A connecting rod shaft 58 is connected between the two mounting plates 51, and an adjusting connecting rod 59 is rotatably connected to the connecting rod shaft 58. An adjusting seat 510 is provided at the lifting platform 52. One end of the adjusting connecting rod 59 is hinged to the adjusting seat 510 through the first connecting rod 511, and the other end is hinged to the connecting shaft 512. The two ends of the connecting shaft 512 are respectively hinged to the two ends of the roller shaft 42 through the second connecting rod 513.

[0047] Specifically, when the blade is pushed by the bamboo shoot, causing the lifting platform to move upward, the adjusting seat pushes the first connecting rod, causing the adjusting connecting rod to rotate along the connecting rod axis, thereby driving the connecting shaft to press down. Then, through the second connecting rod, the downward pressure is transmitted to the saddle-shaped roller, realizing the automatic pressing compensation of the roller on the bamboo shoot.

[0048] In one embodiment of this solution, when no bamboo shoots are passing through, the bottom of the blade maintains a distance of 2mm to 5mm from the conveyor belt, and the bottom of the saddle-shaped roller maintains a distance of 10mm to 15mm from the conveyor belt.

[0049] The mounting plate 51 has an adjustment groove 514 on one side, and the end of the connecting rod shaft 58 is movably installed in the adjustment groove 514, and the connecting rod shaft 58 is perpendicular to the surface of the conveyor belt 2 along the moving direction of the adjustment groove 514.

[0050] Specifically, by setting the adjustment groove, the position of the connecting rod shaft can be adjusted up and down, thereby changing the initial angle and height of the adjusting connecting rod to adapt to the processing needs of bamboo shoots of different specifications; the end of the connecting rod shaft can be fixed in the adjustment groove by bolts to limit the height of the connecting rod shaft during use, thereby precisely controlling the downward stroke and clamping force of the saddle-shaped roller.

[0051] like Figure 3 As shown, the positioning mechanism 3 includes positioning plates 31 connected to both sides of the frame 1 and guide slopes 32 inclined at the ends of the positioning plates 31, so that the bamboo shoots 6 enter between the two positioning plates 31 along the guide slopes 32. Several positioning wheels 33 are sequentially arranged on the positioning plates 31 along the conveying direction of the conveyor belt 2.

[0052] Specifically, the guide slope guides the bamboo shoots to smoothly enter the processing channel between the positioning plates. At the same time, the positioning plates limit the bamboo shoots on both sides to ensure that the bamboo shoots remain centered during the conveying process, avoiding deviation that could lead to inaccurate pressing or cutting positions later. Meanwhile, the positioning wheels can reduce the friction between the bamboo shoots and the positioning plates, allowing the bamboo shoots to move stably with the conveyor belt.

[0053] The positioning wheels can be made of flexible materials, such as rubber.

[0054] like Figure 5 , Figure 6As shown, it also includes a peeling mechanism 7 disposed on the frame 1 and located at the discharge end of the conveyor belt 2. The peeling mechanism 7 includes a first rotating roller 71 rotatably connected to the frame 1 and a second rotating roller 72 rotatably connected to the frame 1 and meshing with the first rotating roller 71. Friction rollers 73 are sleeved on both the first rotating roller 71 and the second rotating roller 72 so that the bamboo shoot shell 61 passes between two adjacent friction rollers 73. A second drive wheel 74 is rotatably disposed on the frame 1. A second synchronous wheel 75 is disposed at the end of the first rotating roller 71 or the second rotating roller 72. A second tension rod 76 is movably connected to the frame 1. A second tension wheel 77 is rotatably sleeved on the second tension rod 76 so that the second synchronous wheel 75, the second tension wheel 77 and the second drive wheel 74 are connected by a second synchronous belt 78.

[0055] Specifically, a motor is installed on the frame, and the motor output shaft is connected to the second drive wheel. Power is then transmitted to the second synchronous wheel through the second synchronous belt, which drives the first and second rotating rollers to rotate in opposite directions. During the peeling operation, the motor drives the friction rollers to rotate inward at a speed of 60~108 rpm. When the bamboo shoot with the peel cut through passes through, the bamboo shoot tips that spread out to both sides, along with the bamboo shoot peel, are rolled into the gap between the two friction rollers facing downward by friction and are forcibly peeled off. Meanwhile, the bamboo shoot meat passes over the friction roller 54 in the original direction, thus achieving the separation of the bamboo shoot peel and meat.

[0056] The frame has a fixed plate with a threaded top bolt. The end of the top bolt is used to tighten the second tension rod. The frame has a slot for the second tension rod to move. A spring is located between the side of the second tension rod away from the top bolt and the slot, so that the position of the second tension wheel can be adjusted by the top bolt, thereby achieving fine adjustment of the tension of the second synchronous belt.

[0057] In one embodiment of this solution, the first and second rotating rollers are arranged in parallel and mounted on the frame via elliptical double-cut-edge bearings. The friction roller is fixed on the two rotating rollers and its surface is covered with a high-friction coefficient anti-slip material. A pair of gears are mounted on the same side of the two rotating rollers and mesh with each other to ensure synchronous reverse rotation.

[0058] The anti-slip material on the surface of the friction roller can be selected from PVC tape with hard abrasive particles on the surface, polyurethane rubber, EVA foam material with a grid pattern on the surface, cork rubber tape, etc.

[0059] During the debugging process, if the diameters of the friction rollers selected in the peeling mechanism are not the same, gears with the corresponding number of teeth can be selected according to the diameter to make the linear speed of the friction rollers the same, so as to achieve uniform force on the bamboo shoots and smooth peeling of the bamboo shoot shells.

[0060] In particular, the peeling mechanism has strict requirements on the minimum gap between the two friction rollers. If the gap is too small, the bamboo shoot shell will be difficult to roll in. If the gap is too large, the rolling friction will be insufficient. The peeling effect is best when the gap is 5~8mm.

[0061] It is worth mentioning that during the continuous peeling of bamboo shoots by the friction rollers, the bamboo shoot tips, which have no edible value, hang downwards and are crushed between the two friction rollers. When the bamboo shoot tips are crushed after the initial peeling, the bamboo shoot shell will split open like a zipper and be rolled off along with the bamboo shoot shell. However, the bamboo shoot flesh has a certain rigidity, and the gap between the friction rollers is not large enough to allow the bamboo shoot flesh to pass through, so it will pass over the friction rollers.

[0062] The working principle of this solution during its implementation is as follows: During operation, bamboo shoots are first placed on the conveyor belt with the tips facing forward. The motor drives the blade shaft, blades, and limit plate to rotate at a high speed of 200-320 rpm via a coupling. Under the action of the conveyor belt, the bamboo shoots first enter the guide area of ​​the positioning plate and are initially centered by the positioning wheels. As the bamboo shoots continue to advance and push against the cutting components, the lifting platform, along with the blades, gradually rises along the flanged linear bearing. The blades smoothly cut the bamboo shoot shell at the radial center, ensuring that the shell is cut to a fixed depth without damaging the bamboo shoot flesh. At the same time, the lifting displacement of the lifting platform pushes one end of the adjusting link through the first connecting rod, forcing the adjusting link to swing. The other end of the adjusting link pushes the second connecting rod, which in turn drives the saddle-shaped roller to move downward, so that the saddle-shaped roller applies precise vertical pressure to the bamboo shoot at the cutting point. The shape of the saddle-shaped roller, combined with this pressing action, ensures that the bamboo shoot is strictly centered at this position and does not shift to the left or right. This perfectly realizes low-resistance conveying in the non-cutting state and adaptive control with linkage pressing only during cutting.

[0063] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
