Technical Field
[0001] This utility model belongs to the field of medicinal material processing technology, specifically relating to a peeling machine for Platycodon grandiflorus. Background Technology
[0002] Platycodon grandiflorus, a commonly used traditional Chinese medicine, contains a large amount of soil, impurities, and fibrous material in its outer skin. Therefore, it needs to be peeled before processing to ensure the purity and efficacy of the herb. Currently, the peeling of Platycodon grandiflorus is mainly done manually, by scraping with a knife or rubbing with sandpaper to remove the outer skin. This method has significant drawbacks: First, it is labor-intensive and extremely inefficient, with each person only able to process a small amount of Platycodon grandiflorus per day, which cannot meet the needs of large-scale production. Second, the peeling is uneven; inconsistent manual operation force and angle can easily lead to unpeeled areas or excessive scraping, causing damage to the Platycodon grandiflorus. Third, the processing quality is unstable, affected by the operator's experience and condition, making it difficult to guarantee the consistency of the finished Platycodon grandiflorus product.
[0003] The existing mechanical peeling equipment is mostly modified from general-purpose agricultural product peeling machines, and is not designed specifically for the long, thin, and tender characteristics of bellflower stems, resulting in several problems: First, the internal cavity structure of the equipment is fixed, and the gaps are not adjustable, so it can only accommodate bellflower stems of a single size, resulting in a narrow range of applications; Second, the contact method between the peeling parts and the bellflower stems is unreasonable, which can easily lead to the accumulation and jamming of the bellflower stems during transportation, or damage to the peel and pulp due to squeezing and scraping; Third, the peeling mechanism and the conveying mechanism have poor coordination, resulting in low peeling efficiency and insufficient uniformity, and some equipment has the problem of incomplete peeling; Fourth, the equipment has poor operational stability, and after long-term use, parts are prone to wear and tear, rotational misalignment, etc., which affects the continuity of processing.
[0004] Therefore, there is an urgent need for a peeling device specifically designed for the characteristics of Platycodon grandiflorus to solve the problems of low efficiency of manual peeling, large damage of mechanical peeling, and poor adaptability, so as to realize efficient, uniform, and low-damage large-scale peeling processing of Platycodon grandiflorus. Utility Model Content
[0005] The purpose of this invention is to provide a peeling machine for bellflower root, which solves the problems of low efficiency in manual peeling.
[0006] The core technical solution of this utility model is as follows: a platycodon peeling machine, comprising a peeling mechanism, a drive mechanism, a frame frame supporting the peeling mechanism and the drive mechanism; the peeling mechanism includes a conical roller screen and a peeling rotor coaxially mounted inside it;
[0007] The peeling rotor includes a central shaft horizontally mounted on a frame via bearings at both ends. Multiple support discs with gradient diameters are installed at equal intervals on the central shaft, with the front support disc having a smaller diameter and the rear support disc having a larger diameter. The multiple support discs mounted on the central shaft are generally conical in shape, and several conical spiral strips are fixedly mounted on the multiple support discs in a ring array. Elastic brush teeth are densely distributed at equal intervals on the conical spiral strips, and scraping metal wires are densely wrapped around the elastic brush teeth.
[0008] The conical roller screen includes a conical screen frame with a small front diameter and a large rear diameter. A front ring rail and a rear ring rail are fixedly installed at the front and rear ends of the conical screen frame, respectively. A conical screen is installed inside the conical screen frame. A front left roller and a front right roller are installed on the frame to support the front ring rail symmetrically below the front ring rail. A rear left roller and a rear right roller are installed on the frame to support the rear ring rail symmetrically below the rear ring rail.
[0009] The drive mechanism includes a rotor speed-regulating motor installed at the lower front of the frame to drive the peeling rotor to rotate and a roller screen speed-regulating motor to drive the conical roller screen to rotate. The rotor speed-regulating motor is connected to the front end of the central shaft through a sprocket mechanism, and the roller screen speed-regulating motor is connected to the front left roller and the front right roller through a sprocket mechanism. The peeling rotor and the conical roller screen rotate in opposite directions.
[0010] A feed hopper for adding citrus stems into the conical sieve is set above the front end of the frame, and a discharge chute for receiving the peeled citrus stems rolled out of the conical sieve is set below the rear end of the frame.
[0011] Preferably, the support disk of the peeling rotor has 6-30 conical spiral strips arranged in a circular array along its circumference. Each conical spiral strip extends spirally 90°-150° along the circumference of the support disk. The spiral direction of the conical spiral strips is matched with the rotation direction of the peeling rotor, ensuring that when the peeling rotor starts to rotate, the strips can simultaneously generate a directional thrust along the central axis on the orange stems in the conical drum screen. This achieves sufficient agitation of the orange stems to improve the uniformity of peeling, and can stably push the orange stems from the front end (feed end) to the rear end (discharge end) of the conical drum screen smoothly, avoiding the accumulation, jamming, or backflow of orange stems in the screen. At the same time, the conical arc of the conical spiral strips is completely fitted with the overall conical structure of the support disk, and the edges of the strips are rounded to reduce the scratch damage to the orange stem skin during the conveying process, thus balancing peeling efficiency and the integrity of orange stem processing.
[0012] Preferably, taking into account the elongated shape of the bellflower and the horizontal conveying requirements of the equipment, the cone angle of the cone screen is set to 10°-20°; at the same time, the conical spiral strips on the peeling rotor are distributed synchronously with the gradient diameter of the support plate, and the overall conical structure formed by the two has a cone angle that is completely consistent with the cone angle of the cone screen. With the conical drum screen and the peeling rotor installed horizontally on their axes, this design creates a gradually widening cavity space from the front end (feed end) to the rear end (discharge end) of the conical drum screen. The screen diameter at the rear end (discharge end) is larger, which on the one hand prevents the stems from accumulating and getting stuck due to the narrow space when conveying them to the end. On the other hand, it can use the weight of the stems themselves and the axial thrust generated by the rotation of the peeling rotor to work together to guide the stems to move smoothly to the discharge end and be discharged. At the same time, the design with a consistent cone angle can ensure that the conical spiral strips and the inner wall of the conical drum screen always maintain a uniform gap. This ensures that the strips agitate and peel the stems evenly, and reduces local compression damage to the stems caused by uneven gaps. This achieves a triple balance of "peeling efficiency, smooth conveying, and stem integrity".
[0013] Preferably, 2-5 conical spiral guide plates are evenly distributed along the circumference of the inner wall of the conical screen. These conical spiral guide plates can be made of steel bars or thin strips, and their width is controlled to 5-10mm to prevent damage to the peel or pulp of the fruit stems due to excessive compression and friction during transport. All conical spiral guide plates must perfectly match the taper of the conical screen to achieve a tight fit with the inner wall (without obvious gaps), preventing the fruit stems from getting stuck and affecting transport. With the screen axis as a reference, each conical spiral guide plate extends spirally 90°-150° along the circumference of the inner wall of the conical screen, and its spiral direction must be compatible with the rotation direction of the conical sieve. To ensure that when the conical drum screen starts rotating, the spiral guide plate of the conical spiral guide plate can be completely consistent with the preset conveying direction of the stalks from the front end (feeding end) to the rear end (discharge end) of the screen, it can not only work together with the axial thrust generated by the peeling rotor to further improve the conveying efficiency, but also fundamentally avoid the problem of stalk collision and accumulation caused by misalignment of the guide direction, and ultimately ensure the smoothness and integrity of the stalk conveying process.
[0014] Preferably, the central hole of the support plate is fixedly connected to the spline bushing (e.g., by welding or bolting), and the spline bushing forms a sliding fit with the corresponding spline shaft on the central shaft. This spline fit structure can ensure that the torque of the central shaft is stably transmitted to the support plate when it rotates (driving the entire peeling rotor to rotate synchronously), and also provides a movable base for the axial adjustment of the peeling rotor. During adjustment, loosen the pre-set set screw on the side wall of the spline bushing (the set screw passes through the spline bushing and presses against the spline tooth surface of the central shaft), and push or pull the support plate along the central shaft axis (driving the peeling rotor as a whole) to adjust the radial gap between the peeling rotor (including the conical spiral strips and elastic brush teeth) and the inner wall of the conical screen. After the gap is adjusted to match the diameter of the currently processed citrus stem (ensuring that the gap allows the citrus stem to pass through smoothly, and that the elastic brush teeth and scraping metal wires can effectively contact the citrus stem surface to achieve peeling, while avoiding damage to the citrus stem due to excessive gap), tighten the set screw again. The set screw fixes the position of the spline bushing by the friction generated by pressing the spline tooth surface, thereby locking the axial position of the peeling rotor and achieving peeling adaptation for citrus stems of different thicknesses.
[0015] Preferably, to achieve smooth rotation and stable support of the conical roller screen, the front left roller is coaxially fixed to the rear left roller via a left drive shaft, and the front right roller is coaxially fixed to the rear right roller via a right drive shaft, with the transmission speeds of the left and right drive shafts remaining consistent. Simultaneously, the four rollers (front left, rear left, front right, and rear right) are tightly fitted to the lower sides of the front and rear ring rails of the conical roller screen, respectively. Through the synergistic effect of the coaxial synchronous rotation of the front and rear rollers on the same side and the matching speeds of the left and right rollers, a four-point balanced support and synchronous drive for the conical roller screen is formed. This ensures that the conical roller screen rotates without deviation or jamming, avoiding wear on the ring rails due to uneven force and guaranteeing a stable rotation speed, providing a stable motion foundation for the peeling and conveying of the platycodon root within the screen.
[0016] Preferably, to improve equipment operation safety and the cleanliness of the operating environment, a protective enclosure is installed around the lower half of the conical drum screen area around the frame; simultaneously, a detachable discharge hood is installed above the discharge chute corresponding to the discharge end of the conical drum screen. The discharge hood is made of stainless steel or transparent acrylic sheet. The protective enclosure and the discharge hood work together to effectively prevent the splashing of mud and peel debris generated during the peeling of the citrus stems during mechanical operation, avoiding pollution of the surrounding operating environment and preventing debris from falling and posing a safety hazard to operators, thus balancing practicality and safety.
[0017] Preferably, the elastic brush teeth are made from a steel wire rope twisted from multiple steel wires, with a diameter of 5-8mm, possessing excellent elasticity and not easily deformed during long-term use; the scraping metal wire is a sawing rope made by winding 2-3 steel wires with a diameter of 0.05-0.1mm, with the sawing rope spirally wound on the surface of the steel wire rope at a pitch of 5-12mm, and fixed and shaped by a high-temperature flame sintering process.
[0018] Working principle of this utility model
[0019] After the citrus stems to be peeled are fed into the conical drum screen through the feed hopper, the rotor speed-regulating motor and the drum screen speed-regulating motor are started:
[0020] The rotor speed-regulating motor drives the central shaft to rotate through the sprocket mechanism, which in turn drives the peeling rotor to rotate synchronously. The conical spiral blades rotate with the support disc, and the elastic brush teeth on their surface open under the action of centrifugal force, making full contact with the barley stem peel. The scraping metal wires on the brush teeth rub and scrape the barley stem peel, achieving peeling. At the same time, the spiral direction of the conical spiral blades is matched with the rotation direction, generating a continuous axial directional thrust on the barley stem, pushing the barley stem to move towards the rear end of the conical drum screen.
[0021] The variable-speed motor of the rotary screen drives the front left and front right rollers to rotate via a sprocket mechanism. This, in turn, drives the rear left and rear right rollers to rotate synchronously via a transmission shaft. This, in turn, drives the conical rotary screen to rotate in the opposite direction. The peeling rotor rotates in the opposite direction to the conical rotary screen (e.g., if the peeling rotor rotates clockwise, the conical rotary screen rotates counterclockwise), creating a relative kneading force. This significantly improves the peeling efficiency of the scraping wire on the surface of the orange stems, while avoiding damage caused by excessive friction between the orange stems and the screen. The conical spiral guide plate on the inner wall of the conical screen rotates with the screen, guiding the orange stems smoothly along a preset direction and preventing collisions and accumulation.
[0022] Within the tapered, gradually changing cavity, the bellflower root moves steadily from front to back, aided by its own gravity, the axial thrust of the peeling rotor, and the guiding effect of the tapered spiral guide plate. During this movement, it continuously contacts the elastic brush teeth and the inner wall of the screen, achieving comprehensive and uniform peeling. The peeled skin fragments fall through the screen aperture, and the peeled bellflower root is discharged from the rear end of the tapered drum screen to the discharge chute, completing the entire peeling process.
[0023] For bellflower stems of different thicknesses, the axial position of the peeling rotor can be adjusted to change the gap between it and the screen, ensuring effective contact for peeling without damaging the bellflower stem due to an excessively small gap.
[0024] Compared with the prior art, the present invention has the following significant advantages.
[0025] 1. Significantly improved peeling efficiency: The automated processing method driven by motors replaces traditional manual operation, greatly reducing labor intensity; the peeling rotor and the conical roller screen rotate in opposite directions, enhancing the rubbing and peeling effect, and the synchronous conveying structure meets the efficiency requirements of large-scale processing.
[0026] 2. Good peeling uniformity: The conical spiral slats are arranged in a ring array, with uniform gap control and cone angle matching design, ensuring that the platycodon is fully agitated during transportation and that the peel fully contacts the scraping wire. This effectively avoids localized unpeeled or incomplete peeling, resulting in high consistency of the finished product.
[0027] 3. Low damage rate of bellflower stems: The edges of the conical spiral strips are rounded, the width of the conical spiral guide plate is strictly controlled, and the elastic brush teeth have excellent elasticity, which reduces scratch damage from the contact method; the adjustable radial gap is adapted to bellflower stems of different thicknesses, avoiding squeezing damage and ensuring the integrity of bellflower stem processing.
[0028] 4. Wide range of applications: The gap between the peeling rotor and the screen can be flexibly adjusted through the axial adjustment structure, which can process stalks of different thicknesses without the need to change equipment or parts, thus reducing processing costs.
[0029] 5. Stable and reliable operation: The four-point balanced support structure and the coaxially fixed roller drive design ensure that there is no deviation or jamming during the rotation of the cone screen, reducing component wear; the variable frequency speed control motor drives smoothly and can adjust the speed according to processing requirements, further improving the stability of the equipment.
[0030] 6. Convenient operation and maintenance: The equipment has a simple structural design, and the processing flow only requires three core steps: feeding, starting, and discharging; the protective enclosure and discharge cover are designed to be detachable, making it easy to clean the debris inside the equipment; the connection method of key components is simple, and the maintenance cost is low.
[0031] 7. Safety and environmental protection: Protective enclosures and discharge hoods prevent debris from splashing, avoid injury to operators, and prevent pollution of the processing environment. Attached Figure Description

[0043] The composition and operation steps of this utility model will be described in detail below with reference to Figures 1 to 10:
[0044] I. Composition and Structure
[0045] Frame 1: The frame structure is made of Q235 carbon steel, with an overall height of 1500mm, a length of 3300mm, and a width of 2000mm. Protective enclosure plates 11 are welded and fixed around the frame 1 to the area corresponding to the cone-shaped roller screen 2. The protective enclosure plates 11 are made of 1.5mm thick stainless steel plate and surround the lower half of the cone-shaped roller screen 2.
[0046] Feed hopper 12 and discharge trough 13: Feed hopper 12 is made of 2mm thick stainless steel plate welded together; discharge trough 13 is made of 2mm thick stainless steel plate, and its end extends to the outside of frame 1 to facilitate the collection of peeled citrus stems; above discharge trough 13, corresponding to the discharge end of cone-shaped roller screen 2, a detachable discharge cover 14 is fixed by bolts, and the discharge cover is made of 1mm thick stainless steel plate.
[0047] Peeling rotor 3:
[0048] The central shaft 31 is made of 45 steel, with a diameter of 50mm and a length of 2900mm. Both ends are horizontally mounted on the bearing seats of the frame 1 through deep groove ball bearings (model 6210). The central shaft 31 has four 6-tooth standard spline shafts 32 machined in the middle, each spline shaft is 300mm long, which are used to mate with four spline shaft sleeves 34.
[0049] The support plate 33 is made of 4mm thick steel plate and is stamped into shape. There are 4 plates, and the diameter increases gradually from 450mm at the front end to 950mm at the rear end. The distance between adjacent support plates 33 is 800mm. The total length occupied by the 4 support plates is 2400mm, which is adapted to the effective installation length of the central shaft 31. The center hole of the support plate 33 is welded and fixed to the spline bushing 34. The spline bushing 34 slides with the spline shaft 32. The side wall of the spline bushing 34 is provided with an M8 internal hexagon set screw (set screw 35) to lock the position of the support plate 33.
[0050] The conical spiral slats 36 are made of spring steel, with a width of 36mm and a thickness of 20mm, and the edges are polished and rounded. Each support plate 33 has 12 conical spiral slats 36 arranged in a ring array. Each slat extends spirally 120° along the circumference of the support plate 33 and is completely fitted with the conical structure of the support plate 33 and fixed by welding.
[0051] The elastic brush teeth 37 are made from a steel wire rope twisted from 7 steel wires, with a diameter of 6mm and a length of 350mm. They are evenly spaced on the conical spiral strip 36 by drilling and welding, with a spacing of 30mm. This spacing meets the requirements for dense distribution, ensuring that adjacent elastic brush teeth cover the stalk conveying path without gaps, thus making full contact with the stalk surface without excessive compression. The scraping wire 38 is a saw rope made by winding 2 steel wires with a diameter of 0.1mm. The saw rope is spirally wound on the surface of the elastic brush teeth 37 with a pitch of 10mm and fixed by high-temperature flame sintering.
[0052] Conical sieve 2:
[0053] The conical screen frame 21 is made of 50×50mm angle steel welded together, with a cone angle of 16°, a front diameter of 830mm, a rear diameter of 1600mm, and a length of 2600mm. The front ring rail 22 and the rear ring rail 23 are made of 10mm thick steel plates welded and fixed to both ends of the conical screen frame 21. The front ring rail 22 is a grooved ring rail (concave, with a U-shaped groove structure in the cross section), and the rear ring rail 23 is a convex ring rail (with a circular arc convex structure in the cross section).
[0054] The conical screen 24 is made of 304 stainless steel and is rolled up with 8mm×8mm square mesh. It is fixed inside the conical screen frame 21 by intermittent circumferential welding with a welding spacing of 50mm to avoid welding deformation affecting the flatness and taper accuracy of the screen. Three conical spiral guide plates 25 are evenly distributed along the circumference of the inner wall of the screen. The conical spiral guide plates are made of steel bars with a diameter of 8mm and extend spirally 120° along the circumference of the inner wall of the screen, which perfectly matches the taper of the screen. They are tightly attached and fixed by welding.
[0055] Drive mechanism:
[0056] Both the rotor speed-regulating motor 41 and the rotary screen speed-regulating motor 42 are variable frequency speed-regulating motors with a power of 1.1kW and a speed adjustment range of 500-3000r / min. They are fixedly installed on the motor base at the lower front of the frame 1. The sprocket mechanism uses a standard roller chain (model 16A). The output shaft of the rotor speed-regulating motor 41 is connected to the sprocket at the front end of the central shaft 31 through a sprocket, with a transmission ratio of 1:1. The output shaft of the rotary screen speed-regulating motor 42 is synchronously connected to the left drive shaft 47 corresponding to the front left roller 43 and the right drive shaft 48 corresponding to the front right roller 44 through the sprocket mechanism. The transmission ratio of the rotary screen speed-regulating motor 42 with the left and right drive shafts is set to 1:1. Power is transmitted synchronously through the symmetrically arranged sprocket mechanism (model 16A). The transmission ratio matching of the sprocket mechanism ensures that the transmission speeds of the left and right drive shafts are completely consistent.
[0057] The circumference ratio of the front left roller 43 to the front ring rail 22 and the front right roller 44 to the front ring rail 22 are both 1:6. The conversion relationship between the rotation speed of the cone roller screen 2 and the rotation speed of the roller screen speed regulating motor 42 is: motor speed = cone roller screen rotation speed × circumference ratio × transmission ratio (example: when the cone roller screen needs to reach 500r / min, the motor speed = 500r / min × 6 × 1 = 3000r / min). This speed is within the adjustment range of 500-3000r / min of the motor, which is suitable for different peeling needs.
[0058] The front left roller 43 and the front right roller 44 are both flange rollers (convex structure, with the center of the roller surface protruding outward, and the size of the protrusion precisely matches the depth of the U-shaped groove of the front ring rail 22 to achieve a tight fit and prevent axial displacement); the rear left roller 45 and the rear right roller 46 are both I-beam rollers (the center of the roller surface has an annular groove, and the width of the groove matches the width of the arc-shaped protrusion of the rear ring rail 23 to fit without gaps). The front left roller 43 and the rear left roller 45 are coaxially fixedly connected through the left drive shaft 47, and the front right roller 44 and the rear right roller 46 are coaxially fixedly connected through the right drive shaft 48. The left drive shaft 47 and the right drive shaft 48 are both made of No. 45 steel, which is heat-treated to enhance toughness. The diameter is 40mm. They are installed on the frame 1 through deep groove ball bearings (the model is compatible with the bearing seat of the frame). The transmission ratio of the sprocket mechanism is matched to ensure that the transmission speed of the left and right drive shafts is completely consistent, so as to realize the four-point balanced drive and smooth rotation of the cone roller screen 2.
[0059] II. Operating Procedures
[0060] Equipment Inspection and Gap Adjustment: Before use, check whether the connections of each component of the equipment are firm, whether the transmission components such as sprockets, chains, and rollers are flexible, and whether the protective enclosure 11 and discharge hood 14 are installed in place; according to the thickness of the stalks to be processed, loosen the set screw 35 on the flower key bushing 34, push or pull the support plate 33 along the central shaft 31 axially, and adjust the radial gap between the peeling rotor 3 and the conical screen 24 (to ensure that the stalks can pass through smoothly and the elastic brush teeth 37 can effectively contact the skin). After adjustment, tighten the set screw 35 to lock the position.
[0061] Feeding preparation: Remove obvious impurities (such as stones and dead branches) from the stalks to be peeled and arrange them in a loose state to avoid knotting and tangling.
[0062] Start the equipment: Connect the power supply and start the rotor speed regulating motor 41 and the sieve speed regulating motor 42 respectively. Adjust the speed according to the condition of the stalks. Freshly harvested stalks are easy to peel, so control the speed of the conical sieve 2 to 300-400 r / min and the speed of the peeling rotor 3 to 500-600 r / min. Stalks that have been stored for a long time are more difficult to peel, so control the speed of the conical sieve 2 to 400-500 r / min and the speed of the peeling rotor 3 to 650-750 r / min. Observe the operation of the equipment to ensure that the conical sieve 2 and the peeling rotor 3 rotate smoothly without abnormal noise or deviation.
[0063] Continuous processing: The prepared bellflower stems are continuously and evenly fed into the feed hopper 12 by manual or mechanical feeding. The bellflower stems naturally slide into the conical roller screen 2 through the feed hopper 12. During the processing, the feeding is kept uniform to avoid the accumulation and jamming caused by feeding a large amount of material at one time. The conveying and peeling of the bellflower stems are observed. If the peeling is incomplete, the speed can be increased appropriately. If the bellflower stems are damaged, the speed can be reduced or the gap can be adjusted.
[0064] Finished product collection: The peeled bellflower stems are discharged from the rear end of the conical drum screen 2 to the discharge chute 13, and slide down the inclined chute for output. The output bellflower stems are cleaned regularly to avoid accumulation and blockage.
[0065] Shutdown and cleaning: After all the bellflower roots have been processed, continue running the equipment for 3-5 minutes to remove any remaining debris; turn off the rotor speed control motor 41 and the roller screen speed control motor 42, and disconnect the power supply; clean the mud and surface debris inside the cone roller screen 2, the discharge chute 13, and the inner side of the protective enclosure 11 to ensure that the equipment is clean and free of residue for the next use.
[0066] Maintenance: Regularly check the chain tension and add lubricating oil if necessary; check the wear of the elastic brush teeth 37 and scraping metal wires 38, and replace them in time if the wear is serious; check the operating status of rollers, bearings and other components, and repair or replace them in time if any abnormalities are found.
