Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a pre-treatment device for fresh bamboo used in the production of fresh bamboo sap. Background Technology

[0002] Fresh bamboo sap is a traditional Chinese medicine with heat-clearing and phlegm-resolving effects. With the increasing market demand for fresh bamboo sap in recent years, the manufacturing industry needs to accelerate its upgrading and modernize production to improve efficiency and ensure capacity. The production process of fresh bamboo sap first requires disease detection of fresh bamboo, then cutting it into appropriately sized sections, and finally dividing the sections into strips of roughly equal width. However, existing fresh bamboo cutting and stripping equipment is inefficient, and most processes rely on manual labor; improper operation by workers can even lead to production accidents.

[0003] Chinese invention patent application number 202210721622.8 discloses a novel rapid bamboo splitting machine, which employs a bamboo splitting component, a film-breaking component, and a pushing component. It can hold bamboo against a blade holder and split the bamboo through feeding. However, during feeding, the top structure may not provide sufficient holding pressure, and the pushing component may not provide enough friction, causing the bamboo to break and shift laterally during splitting. Furthermore, bamboo of different thicknesses results in inconsistent sizes of the finished bamboo strips, leading to poor uniformity and hindering subsequent processing. Chinese utility model patent application number 201320768096.7 discloses a novel bamboo-cracking machine structure, which uses a circular array of bamboo guide sleeves. Raw bamboo is fed into the bamboo guide sleeves and supported by a bottom die. A hydraulic cylinder then drives a crashing head downwards into the bamboo guide sleeve to impact the raw bamboo, splitting it into strips. This device can split multiple bamboo poles at once to improve production efficiency; however, because the die is not adjustable, it cannot ensure the uniformity of the finished bamboo strips. In addition, existing equipment can generally only perform the task of splitting bamboo, lacking the function of detecting and removing diseased parts. Performing each operation separately wastes a lot of human resources, and the degree of mechanization is low.

[0004] In summary, there are currently no records of equipment suitable for different diameters, with stable feeding and conveying capabilities, and capable of detecting diseases in fresh bamboo. Therefore, there is an urgent need to incorporate new technologies and design concepts to develop a pre-treatment device for fresh bamboo in the production of fresh bamboo sap, in order to achieve high-quality automated detection, segmentation, and fragmentation of fresh bamboo of different specifications. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a pre-treatment device for fresh bamboo in the production of fresh bamboo sap. It can remove potentially diseased sections of bamboo stalks and can control the selection of different numbers of blade holders for slicing operations according to the diameter of the bamboo stalks, resulting in better uniformity of the finished bamboo strips, ensuring the quality of the raw materials. The device has a high degree of overall automation, saving manpower while being safer and more efficient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fresh bamboo pretreatment device for the production of fresh bamboo sap, comprising a frame, a bamboo cutting platform, a diseased bamboo segment detection mechanism, a diseased bamboo segment removal mechanism, and a bamboo conveying and splitting platform;

[0007] The front end of the frame is connected to a fixed angle iron conveyor frame along its longitudinal direction, and the frame is equipped with a control panel for the operation control of all electrical components.

[0008] The diseased bamboo segment detection mechanism includes a rotating disk installed at the front end of the frame and an optical detector installed on its inner rotating ring. The rotating disk is encircled outside the angle iron conveyor frame, and the optical detector collects surface images of the bamboo poles.

[0009] The bamboo pole cutting platform includes a clamping cylinder, an electric telescopic rod, and a cutting motor. The clamping cylinder is fixed laterally to the front end of the frame surface. The telescopic end of the clamping cylinder and the frame surface are respectively fixed with clamping plates. The cutting motor coaxially fixes the saw blade and lowers and raises the saw blade through the electric telescopic rod.

[0010] The diseased bamboo segment removal mechanism includes a propulsion cylinder that is fixed laterally to one side of the frame surface at the middle position.

[0011] The bamboo-splitting platform includes a feeding clamp, a distance sensor, a diameter detection sensor, a conveying mechanism, and a bamboo-splitting mechanism. The feeding clamp consists of an electric slide and an electric clamp, and is installed on the frame surface near the front end of the diseased bamboo segment removal mechanism. The distance sensor and the diameter detection sensor are respectively installed on one side of the frame surface near the front end to collect real-time information on the feeding distance and diameter of the bamboo pole. The conveying mechanism and the bamboo-splitting mechanism are sequentially installed at the rear end of the frame. The conveying mechanism supplies the bamboo segments provided by the feeding clamp to the axis of the bamboo-splitting mechanism. The bamboo-splitting mechanism includes multiple sets of blade holders fixed on the frame and arranged coaxially and at intervals along the longitudinal direction. Each set of blade holders consists of a ring plate and three blades evenly fixed on its surface and arranged radially. The blades can be adjusted in radial position to select whether to act on the bamboo segment, and the blades in the multiple sets of blade holders are staggered.

[0012] Furthermore, the cutting tool includes a fixed base, a bamboo splitting blade head, and a blade shank. The fixed base is fixedly connected to the surface of the annular plate by screws. The tip of the bamboo splitting blade head has a V-shaped structure, and a chip removal groove is machined in the middle position, with a peeling blade and a slicing blade fixed thereon. The blade shank is fixedly mounted on the back of the bamboo splitting blade head. The blade shank includes a central guide rod and two side strip rods, which are slidably engaged with the fixed base respectively. The end of the central guide rod of the blade shank passes through the fixed base and is threaded with a positioning nut. The positioning nut is controlled to rotate forward and backward by a torque motor installed on the fixed base using a quick-connect socket wrench. A compression spring is also fitted on the central guide rod of the blade shank to provide elastic support for the fixed base and the bamboo splitting blade head.

[0013] Furthermore, the conveying mechanism includes an n-shaped bracket, a floating plate, two fixed conveying rollers, two floating conveying rollers, and four guide rods. The n-shaped bracket is fixed horizontally across the surface of the frame. The two fixed conveying rollers are arranged longitudinally at intervals and rotatably mounted on the bottom inner side of the n-shaped bracket. One end of the roller shaft of each of the two fixed conveying rollers is coaxially fixed to a driven pulley and connected to a drive belt. The other end of the roller shaft of one of the fixed conveying rollers is coaxially fixed to a drive pulley and connected to a motor via a drive belt. The floating plate is located on the top inner side of the n-shaped bracket. The two floating conveying rollers are arranged longitudinally at intervals and rotatably mounted on the bottom of the floating plate. The roller shafts of the two floating conveying rollers are respectively slidably engaged with the vertical grooves prefabricated at corresponding positions on both sides of the n-shaped bracket. The bottom ends of the four guide rods are evenly fixed at the middle position on the upper surface of the floating plate, and the four guide rods are slidably engaged with the guide holes prefabricated at corresponding positions on the top of the n-shaped bracket.

[0014] Furthermore, an adjustment plate is provided between the top of the n-shaped bracket and the floating plate. The adjustment plate has four through holes at corresponding positions and is slidably installed between four guide rods. Compression springs are respectively sleeved on the four guide rods and supported between the adjustment plate and the floating plate. An adjustment bolt is coaxially rotatably installed at the center of the upper surface of the adjustment plate. The adjustment bolt is screwed into the pre-made screw hole at the center of the top of the n-shaped bracket.

[0015] Furthermore, the two floating conveyor rollers adopt an arc-shaped contact surface that gradually tapers from both ends towards the center.

[0016] Furthermore, the diseased bamboo segment removal mechanism also includes a diseased bamboo waste bin placed at the bottom of the other side of the frame in the middle position.

[0017] Furthermore, the bamboo-splitting mechanism also includes a waste fragment bin placed at the bottom of the rear end of the frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model installs a diseased bamboo segment detection mechanism at the bamboo pole feeding position at the front of the frame. The optical detector with visual imaging surrounds the bamboo pole under the drive of the rotating disk, collects the surface image of the bamboo pole and transmits it to the control panel. By comparing it with the predefined image of healthy fresh bamboo, it can be determined whether there are diseased segments in the bamboo pole. This makes it easier to remove the diseased bamboo segments using the diseased bamboo segment removal mechanism in the subsequent process, ensuring that the bamboo segments entering the subsequent bamboo splitting process are all disease-free bamboo segments, which significantly improves the production quality of finished bamboo strips.

[0020] 2. The conveying mechanism of this utility model adopts rolling friction conveying by combining fixed conveying rollers and floating conveying rollers. The floating conveying rollers can adapt to the transportation of bamboo segments of different diameters under the action of compression springs. Furthermore, the arc-shaped contact surface design applies squeezing force to both sides of the bamboo segment, effectively preventing the bamboo segment from shifting laterally and becoming skewed during the splitting process. The conveying is more stable. Combined with the intermittent feeding of the feeding clamp, the equipment has a high degree of mechanical automation during the processing, saving manpower while being safer and more efficient.

[0021] 3. The bamboo splitting mechanism of this utility model is composed of multiple sets of blade holders connected axially. Each set of blade holders is evenly loaded with three bamboo splitting blades, and the bamboo splitting blades between the multiple sets of blade holders are staggered. The radial position of the bamboo splitting blades can be adjusted by a torque motor, thereby selecting whether to act on the surface of the bamboo segment. Different numbers of blade holders can be selected for cutting strips according to the collected bamboo pole diameter information, so as to improve the uniformity of the finished bamboo strips.

Detailed Implementation

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0032] like Figures 1 to 8 As shown, a fresh bamboo pretreatment device for the production of fresh bamboo sap includes a frame 27, a bamboo cutting platform, a diseased bamboo segment detection mechanism, a diseased bamboo segment removal mechanism, and a bamboo conveying and splitting platform.

[0033] Combination Figure 1 As shown, the frame 27 serves as the foundation of the overall device and is used to support and install the bamboo cutting platform, the diseased bamboo segment detection mechanism, the diseased bamboo segment removal mechanism, and the bamboo conveying platform. The front end of the frame 27 is longitudinally connected to a fixed angle iron conveyor frame 1 for supporting and feeding the bamboo poles. The frame 27 is also equipped with a control panel 7 and a power switch 8 for controlling the operation of all electrical components and switching the power supply on and off.

[0034] Combination Figure 2As shown, the bamboo cutting platform includes a clamping cylinder 9, a saw blade 10, clamping plates 11, an electric telescopic rod 12, and a cutting motor 13. The clamping cylinder 9 is fixed laterally to the surface of the frame 27 near the front end. The telescopic end of the clamping cylinder 9 and the surface of the frame 27 are respectively fixed with clamping plates 11. The clamping channel formed between the two clamping plates 11 is coaxially arranged with the angle iron conveyor frame 1, which can clamp and position the bamboo poles fed in by the angle iron conveyor frame 1. To enhance the stability during the clamping of the bamboo poles, it is advisable to use two sets of clamping cylinders 9 arranged longitudinally at intervals. An electric saw mounting column is set on the surface of the frame 27, which is laterally adjacent to the clamping cylinder 9. The housing of the cutting motor 13 is hinged to the bottom of the electric saw mounting column through a connecting frame. The two ends of the electric telescopic rod 12 are respectively hinged to the housing of the cutting motor 13 and the top of the electric saw mounting column. The saw blade 10 is coaxially fixed with the motor shaft of the cutting motor 13. The telescopic movement of the electric telescopic rod 12 can realize the lowering and raising of the saw blade 10 to cut the bamboo pole at the clamping channel.

[0035] Combination Figure 4 As shown, the diseased bamboo segment detection mechanism includes an optical detector 5 and a rotating disk 6. The rotating disk 6 is fixedly installed at the front end of the frame 27 and surrounds the angle iron conveyor frame 1. Three optical detectors 5 are evenly installed circumferentially on the inner ring of the rotating disk 6. The optical detectors 5 are used to capture surface images of the bamboo poles and transmit them to the control panel 7 for display. The operator compares the images with predefined images of healthy fresh bamboo on the control panel 7 to determine whether there are diseased segments on the bamboo poles. If so, after the segmenting operation is completed, the diseased bamboo segment removal mechanism removes the diseased segments to ensure that the raw materials in subsequent processing are free of disease and improve the quality of the raw materials.

[0036] Combination Figure 3 As shown, the diseased bamboo segment removal mechanism includes a propulsion cylinder 14 and a diseased bamboo waste bin 15. The propulsion cylinder 14 is fixed laterally to one side of the surface of the frame 27 at the middle position, and the diseased bamboo waste bin 15 is placed at the bottom of the other side of the frame 27 at the middle position. The diseased segments can be pushed out and fall into the diseased bamboo waste bin 15 for collection by the extension action of the propulsion cylinder 14.

[0037] Combination Figures 1-3As shown, the bamboo-splitting platform includes a feeding clamp 2, a distance sensor 3, a diameter detection sensor 4, a conveying mechanism, and a bamboo-splitting mechanism. The feeding clamp 2 is installed on the surface of the frame 27 near the front end of the diseased bamboo segment removal mechanism. The feeding clamp 2 consists of an electric slide and an electric clamp. The electric slide is coaxially arranged with the angle iron conveyor frame 1, allowing control of the electric clamp's displacement in the front-back direction. The electric clamp can perform clamping and opening / closing actions, thereby intermittently conveying the bamboo poles fed in by the angle iron conveyor frame 1 backwards in conjunction with the displacement of the electric slide. The distance sensor 3 and the diameter detection sensor 4 are respectively installed on one side of the surface of the frame 27 near the front end, used to collect real-time information on the bamboo pole's feeding distance and diameter. The conveying mechanism and the bamboo-splitting mechanism are sequentially installed on the surface of the frame 27 behind the diseased bamboo segment removal mechanism. The conveying mechanism receives the bamboo segments intermittently fed in by the feeding clamp 2 and supplies them to the bamboo-splitting mechanism, which then peels and cuts the fed bamboo segments into strips.

[0038] Combination Figures 5-6As shown, the conveying mechanism includes an adjusting plate 19-4, an n-shaped bracket 19-6, a floating plate 19-7, two fixed conveying rollers 19-1, two floating conveying rollers 19-2, and four guide rods 19-5. The n-shaped bracket 19-6 is fixed across the surface of the frame 27. The two fixed conveying rollers 19-1 are arranged longitudinally at intervals and rotatably mounted on the bottom inner side of the n-shaped bracket 19-6. One end of the roller shaft of each of the two fixed conveying rollers 19-1 is coaxially fixed to a driven pulley 19-8 and connected to it via an O-ring rubber belt. The other end of the roller shaft of one of the fixed conveying rollers 19-1 is coaxially fixed to a driving pulley 18 and connected to a motor 16 via a transmission belt 17. The motor 16 is fixedly mounted at the bottom of the frame 27. Starting the motor 16 can drive the two fixed conveying rollers 19-1 to rotate via the transmission belt 17, supplying the bamboo segments fed into the feeding clamp 2 to the bamboo splitting mechanism. The floating plate 19-7 is positioned on the top inner side of the n-shaped bracket 19-6. Two floating conveying rollers 19-2 are longitudinally spaced and rotatably mounted on the bottom of the floating plate 19-7. The roller shafts of the two floating conveying rollers 19-2 are respectively slidably engaged with pre-fabricated vertical grooves at corresponding positions on the two side arms of the n-shaped bracket 19-6. The bottom ends of four guide rods 19-5 are evenly fixed at the center of the upper surface of the floating plate 19-7. The four guide rods 19-5 are slidably engaged with pre-fabricated guide holes at corresponding positions on the top of the n-shaped bracket 19-6, thereby restricting the vertical displacement of the floating plate 19-7 and the two floating conveying rollers 19-2 at its bottom within the n-shaped bracket 19-6. The adjusting plate 19-4 is positioned between the top of the n-shaped bracket 19-6 and the floating plate 19-7. Four through holes are opened at corresponding positions on the adjusting plate 19-4, which is slidably installed between four guide rods 19-5. Compression springs 19-3 are respectively fitted onto the four guide rods 19-5 and supported between the adjusting plate 19-4 and the floating plate 19-7. An adjusting bolt is coaxially mounted at the center of the upper surface of the adjusting plate 19-4. The adjusting bolt is screwed into a pre-drilled screw hole at the center of the top of the n-shaped bracket 19-6. Rotating the adjusting bolt changes the compression of the four compression springs 19-3 by the adjusting plate 19-4, thereby adjusting the clamping force of the two floating conveyor rollers 19-2 on the bamboo segments. This allows for stable rearward transport of bamboo segments of different diameters through rolling friction. To prevent the bamboo segments from shifting laterally and becoming skewed, the two floating conveyor rollers 19-2 adopt an arc-shaped contact surface design that gradually narrows from both ends towards the center, helping to ensure that the bamboo segments are always supplied axially to the bamboo-splitting mechanism in the center position.

[0039] Combination Figure 5 , Figures 7-8As shown, the bamboo splitting mechanism includes a waste shard bin 28 and multiple sets of blade holders arranged coaxially along the longitudinal direction on the frame 27. The waste shard bin 28 is placed at the bottom of the rear end of the frame 27 to collect the outer skin cut off from the bamboo segments. Each set of blade holders consists of an annular plate 22 and three blades evenly fixed on its surface and arranged radially. The annular plates 22 of the multiple sets of blade holders are connected and fixed together by multiple connecting rods 24. Four fixing plates 25 are respectively set at the beginning and end of the multiple sets of blade holders and are connected and fixed to four positioning rods 29 fixed on both sides of the rear end of the frame 27. The outer end of the fixing plate 25 is preferably connected to the positioning rod 29 by a combination of a sliding sleeve and a screw fastening method, so as to adjust the distance between the multiple sets of blade holders and the conveying mechanism. The blades of the multiple sets of blade holders are staggered, which can perform multi-angle cutting operations on the bamboo segments. The cutting tool includes a fixed base 21, a bamboo splitting blade 23, and a blade shank 26. The fixed base 21 is fixedly connected to the surface of the annular plate 22 by screws. The tip of the bamboo splitting blade 23 has a V-shaped structure and a chip removal groove is machined in the middle position, and a peeling blade 23-1 and a slicing blade 23-2 are fixed thereon. The blade shank 26 is fixedly mounted on the back of the bamboo splitting blade 23. The blade shank 26 includes a central guide rod and two side strip rods, which are slidably engaged with the fixed base 21 respectively. The end of the central guide rod of the blade shank 26 passes through the fixed base 21 and is threadedly connected to a positioning nut. A compression spring 20 is also sleeved on the central guide rod of the blade shank 26 to provide elastic support for the fixed base 21 and the bamboo splitting blade 23. The radial position of the bamboo splitting blade 23 on the annular plate 22 can be adjusted by rotating the positioning nut. This action is achieved by the forward and reverse rotation of a torque motor installed on the fixing seat 21 of each blade. The housing of the torque motor is connected and fixed to the fixing seat 21. The output shaft of the torque motor is equipped with a quick-connect socket wrench that cooperates with the positioning nut. However, for ease of viewing, the specific structure of the torque motor is not shown in the figure.

[0040] This device operates from two stations: the angle iron conveyor frame 1 and the control panel 7. One operator manually places the bamboo poles onto the angle iron conveyor frame 1 and pushes them towards the rear of the frame 27. The other operator controls the entire machine via the control panel 7, including:

[0041] The bamboo pole is intermittently fed backward by the feeding clamp 2 operated by the control panel 7. During this time, the distance sensor 3 collects the feeding distance of the bamboo pole in real time and displays it on the control panel 7. When the required cutting length of bamboo segment is reached, the feeding of the feeding clamp 2 stops. The diameter detection sensor 4 collects the diameter of the bamboo pole and displays it on the control panel 7. The clamping cylinder 9 is clamped by the control panel 7. The cutting motor 13 is started and the electric telescopic rod 12 is extended by the control panel 7. The bamboo pole is cut into segments by the falling saw blade 10. After the segment is cut, the electric telescopic rod 12 is retracted to lift the saw blade 10. The clamping cylinder 9 retracts and resets. The operation is repeated to cut the bamboo pole into multiple segments as required. Simultaneously, during the bamboo pole feeding process, the control panel 7 operates the rotating disk 6, which drives three optical detectors 5 to rotate around the bamboo pole. The three optical detectors 5 capture images of the bamboo pole's surface and transmit them to the control panel 7 for display. The operator compares these images with predefined images of healthy fresh bamboo on the control panel 7 to determine if there are any diseased sections on the bamboo pole. Under the continuous feeding of the feeding clamp 2, the subsequently cut bamboo segments gradually push the previously cut bamboo segments towards the rear conveying and splitting platform. If diseased sections are present, the control panel 7 operates the extension of the propulsion cylinder 14 to push the diseased sections out and collect them in the diseased bamboo waste bin 15. When the bamboo segments are pushed between the fixed conveying rollers 19-1 and the floating conveying rollers 19-2 of the conveying mechanism, the control panel 7 operates the start of the motor 16. The motor 16 drives the two fixed conveying rollers 19-1 to rotate via the transmission belt 17 and the O-ring rubber belt. Under the pressing cooperation of the two floating conveying rollers 19-2, the rolling friction force is used to convey the bamboo segments towards the rear splitting mechanism. Under the action of the conveying mechanism, the bamboo segments pass through multiple sets of blade holders along the axis of the bamboo splitting mechanism. Before this, the operator uses different numbers of blade holders to cut the bamboo segments into strips according to the diameter of the bamboo pole. If the diameter of the bamboo segment is large, the corresponding torque motor is operated through the control panel 7 to concentrate the three bamboo splitting blades 23 of more sets of blade holders at the center of the annular plate 22 so as to act on the bamboo segment. Conversely, if the diameter of the bamboo segment is small, the corresponding torque motor is operated through the control panel 7 to expand the three bamboo splitting blades 23 of more sets of blade holders to the edge of the annular plate 22 so as not to contact the bamboo segment. This achieves a more uniform strip cutting task for bamboo segments of different diameters (for example, thicker bamboo segments are divided into 6 strips, while thinner bamboo segments are divided into 3 strips, so that the thickness of the single strips formed by the two is more similar). As the bamboo segment passes through the bamboo splitting mechanism along the axis, the peeling blade 23-1 of the splitting blade 23 peels off the outer skin of the bamboo segment and drops it into the waste fragment bin 28. The slicing blade 23-2 of the splitting blade 23 evenly cuts the cross-section of the bamboo segment into multiple strips, which are then transferred to the next process at the rear end of the frame 27 by manual labor or conveyor belt.
