Description

Technical Field

[0001] This invention relates to the field of agricultural product processing technology, specifically to a device for peeling Platycodon grandiflorus (a type of medicinal herb). Background Technology

[0002] Platycodon grandiflorus, also known as bellflower, white medicine, and wild ginseng, is a plant belonging to the genus Platycodon in the family Campanulaceae. It can be made into a pickled vegetable with a unique flavor and high nutritional value. Its roots can also be used as medicine, with effects such as clearing the lungs, dispelling cold, relieving cough and phlegm, and draining pus. However, the skin of Platycodon grandiflorus is relatively hard, and the outer skin must be peeled off before eating or using it as medicine.

[0003] When using a bellflower peeling machine to peel bellflowers, the bellflowers are first placed inside the machine. The machine peels the bellflowers by rotating multiple peeling rollers. There are two types of peeling rollers: one type has bristles installed on the peeling roller with friction protrusions on the bristles, and the other type has friction protrusions directly installed on the peeling roller. The principle of both types of peeling rollers is the same: after the peeling roller rotates, the friction protrusions contact the bellflower peel, and then the bellflower peel is peeled off through mechanical friction.

[0004] The surface of the friction protrusion has micro-grooves. During the friction process, the peeled bellflower bark flakes will embed into the depressions of the protrusion. The adhered bark flakes form an "isolation layer" on the surface of the friction protrusion, preventing the tip of the protrusion from directly contacting the bellflower bark. Therefore, when the bellflower is rubbed again in the future, deformation rather than rigid peeling will easily occur, making it difficult for the bellflower bark to be effectively scraped off. Summary of the Invention

[0005] The purpose of this invention is to provide a device for peeling Platycodon grandiflorus, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a device for peeling Platycodon grandiflorus, comprising a main body of the Platycodon grandiflorus peeling machine and a peeling roller, the peeling roller being rotatably disposed within the main body of the Platycodon grandiflorus peeling machine, and further comprising,

[0007] Multiple peeling rods, which are elastic, extend vertically outward from the outer peripheral wall of the peeling roller, and the multiple peeling rods are arranged at intervals along the outer peripheral surface of the peeling roller.

[0008] Multiple diagonal braces, each corresponding to a peeling rod, are hinged to the outer peripheral wall of the peeling roller. The diagonal braces extend at an inclination toward the head of the peeling rod, with the inclination direction facing the rotation direction of the peeling roller. A slip ring is provided at the extended end of the diagonal brace, which is used to slide along the axial direction of the peeling rod toward the side closer to the peeling roller when the peeling rod comes into contact with and deforms with the Platycodon grandiflorus medicinal material.

[0009] Furthermore, it also includes multiple protrusions, which are spaced apart along the axial direction of the peeling rod, and each protrusion extends outward from the outer peripheral wall of the peeling rod;

[0010] Each protrusion is at least partially provided to correspond to the diagonal brace.

[0011] Furthermore, the protrusion has a cavity inside, and the peeling rod corresponding to the protrusion is provided with an inwardly recessed second deformation groove. The second deformation groove is located at the edge end of the outer peripheral wall of the peeling rod and communicates with the cavity. There is a gap between the edge end of the second deformation groove and the contact end of the protrusion and the peeling rod.

[0012] Furthermore, the distance between the two sides of the second deformation groove gradually increases outward along the radial direction of the peeling rod.

[0013] Furthermore, a protrusion is formed by extending outward from the bottom of the second deformation groove as the base surface. The protrusion protrudes from the outer peripheral wall of the peeling rod, and the extended end of the protrusion has a gap with the protruding cavity.

[0014] Furthermore, a first deformation groove is provided on the outer peripheral wall of the peeling rod. The distance between the two side walls of the first deformation groove gradually increases outward along the radial direction of the peeling rod. The first deformation groove is located in the bending direction of the peeling rod and is close to the outer wall of the peeling roller.

[0015] Furthermore, the peeling rod is designed to gradually narrow along its length at the end furthest from the peeling roller, and a brush is fixedly connected to the narrowed end of the peeling rod. The brush is elastic and has a smooth outer surface.

[0016] Furthermore, the slip ring also includes a sleeve rod and a connecting rope, which are connected end to end to form a slip ring with a complete closed shape;

[0017] The sleeve is located between the diagonal brace and the peeling rod. One side of the sleeve is connected to the diagonal brace, and the other side abuts against the peeling rod.

[0018] The connecting rope is wound in a spiral shape and is looped around the peeling rod, and is in close contact with the outer wall of the peeling rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, after the peeling rod contacts the bellflower stem, it peels off the outer skin through flexible pressure and frictional shearing force. When the free end of the peeling rod is obstructed and bends upon contact with the bellflower stem, the inclined support tilts. The end of the inclined support near the peeling rod slides along the arc of the bending of the peeling rod with the slip ring. After the peeling rod turns away from the bellflower stem, it elastically straightens. When the slip ring slides back to its original position, it rubs against the outer wall of the peeling rod, pushing the bellflower skin on the peeling rod to the end of the peeling rod. Then, it is thrown out with centrifugal force to ensure that the peeling rod continues to effectively peel the bellflower stem.

[0021] 2. In this invention, when the peeling rod is bent, the outer end of the second deformation groove opens to release the outer tensile stress. Multiple deformation grooves share the stress. When the protrusion bends, it is stretched and stores elastic potential energy. At the same time as the second deformation groove unfolds, the edge curls up and abuts against the inner wall, keeping the protrusion in a protruding state, making the slip ring slide more smoothly. The protrusion adheres tightly to the stalk with its elastic potential energy. When impacted, it springs back to dissipate force, preventing the stalk peel from getting stuck, making it easier for the slip ring to push it out, and ensuring the peeling effect.

[0022] 3. In this invention, when the two sides of the protrusion are stretched and the height is reduced, the protrusion supports the middle part, preventing excessive collapse of the center. At the same time, there is a gap between the inner wall of the protrusion and the outer wall of the protrusion. During the bending and straightening process of the peeling rod, the slip ring pushes the left and right sides of the protrusion to alternately contact the protrusion when sliding back and forth. The tilt angle of the two sides of the protrusion gradually becomes gentler, reducing the resistance to the slip ring and reducing the risk of the slip ring getting stuck. As a small protruding structure, the protrusion has little resistance to the sliding of the slip ring, ensuring that it can smoothly push away the platycodon peel. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0035] This invention provides a technical solution:

[0036] See Figures 1-7 As shown, a device for peeling Platycodon grandiflorus (a type of medicinal herb) includes a main body 1 and a peeling roller 2. The peeling roller 2 is rotatably disposed within the main body 1. The device also includes...

[0037] Multiple peeling rods 3 are elastic and extend vertically outward from the outer peripheral wall of peeling roller 2. The multiple peeling rods 3 are arranged at intervals along the outer peripheral surface of peeling roller 2.

[0038] Multiple inclined supports 6 are connected to the outer peripheral wall of the peeling roller 2, corresponding one-to-one with the peeling rod 3. The inclined supports 6 extend obliquely towards the rod head of the peeling rod 3, and the oblique direction is set with the rotation direction of the peeling roller 2. A slip ring 7 is provided at the extended end of the inclined support 6, which is used to slide along the axial direction of the peeling rod 3 towards the side closer to the peeling roller 2 when the peeling rod 3 comes into contact with the Platycodon grandiflorus medicinal material and deforms.

[0039] First, start the main body 1 of the bellflower peeling machine. At this time, multiple peeling rollers 2 will rotate synchronously. Then, pour the unpeeled bellflowers into the main body 1 of the bellflower peeling machine. The rotating peeling rollers 2 drive multiple peeling rods 3 to rotate together. The end of the peeling rod 3 away from the peeling roller 2 will directly contact the bellflower. The peeling rod 3 is fixedly installed on the outer wall of the peeling roller 2. Figure 1 As can be seen, the peeling roller 2 is located inside the main body 1 of the bellflower peeling machine. After the bellflower enters the main body 1, the peeling roller 2 and the peeling rod 3 are located on the right side of the bellflower. Figure 2 In this case, the peeling roller 2 rotates counterclockwise, so the peeling rod 3 will rotate down from the upper right to the lower left and come into contact with and rub against the bellflower stem during this movement;

[0040] The peeling rod 3 contacts the surface of the bellflower and generates flexible pressure. This pressure can conform to the irregular cylindrical surface of the bellflower to adapt to the bending or thickness change of the stem, and can also break the bonding force between the outer skin and the stem body through frictional shear force, so that the bellflower skin is gradually peeled off. The number of inclined support parts 6 is equal to that of the peeling rod 3, and one end of the inclined support part 6 is hinged to the outer wall of the peeling roller 2.

[0041] Next Figure 3 and Figure 4From the perspective of the angled brace 6, when the left end of the diagonal brace 6 is close to the left end of the peeling rod 3, the angled brace 6 cannot swing downwards, but can only swing upwards. Therefore, the downward swing amplitude of the angled brace 6 can only reach... Figure 3 and Figure 4 This angle;

[0042] Both the right end of the diagonal brace 6 and the peeling rod 3 are fixedly connected to the outer wall of the peeling roller 2. The left end of the diagonal brace 6 is close to the left end of the peeling rod 3. Since the rotation trajectory of the peeling rod 3 is from the upper right to the lower left, the lower left end of the peeling rod 3 will first contact the stem. The end of the peeling rod 3 connected to the peeling roller 2 is considered the fixed end, and the end of the peeling rod 3 away from the peeling roller 2 is considered the free end. When the free end of the peeling rod 3 comes into contact with the stem, the stem will generate a resistance to the free end of the peeling rod 3 in the opposite direction of movement. Under the action of the resistance, a bending moment is generated, causing the peeling rod 3 to bend to the upper left.

[0043] The diagonal brace 6 is positioned exactly in the opposite direction to the bending direction of the peeling rod 3, according to... Figure 3 and Figure 4 From the perspective of the angle, after the peeling rod 3 bends upward, the free end of the peeling rod 3 will gradually move away from the left end of the diagonal brace 6. The diagonal brace 6 is connected to the peeling rod 3 through the slip ring 7. The slip ring 7 is sleeved on the outer wall of the peeling rod 3. When the free end of the peeling rod 3 bends upward, the slip ring 7 will slide towards the fixed end of the peeling rod 3 along the slope of the peeling rod 3. At this time, since the free end of the peeling rod 3 moves away from the diagonal brace 6, the left end of the diagonal brace 6 will slide along the peeling rod 3 with the slip ring 7. The diagonal brace 6 will also tilt upward. Depending on the degree of bending of the peeling rod 3, the position of the left end of the diagonal brace 6 and the slip ring 7 on the peeling rod 3 will also be different.

[0044] Then, after the bent peeling rod 3 turns away from the bellflower root, the peeling rod 3 straightens back due to its own elasticity. The left end of the inclined support 6 and the slip ring 7 slide back towards the free end of the peeling rod 3. During this process, the inner ring surface of the slip ring 7 rubs against the outer wall of the peeling rod 3, pushing the bellflower root peels adhering to the peeling rod 3 towards the free end of the peeling rod 3. The bellflower root peels are concentrated and piled up at the left end of the inclined support 6 and the peeling rod 3. As the peeling roller 2 rotates, the centrifugal force generated will also help to throw out some of the bellflower root peels.

[0045] Since the peeling rod 3 rotates down from the upper right to the lower left, only the lower surface of the peeling rod 3 will contact the bellflower root, which is the opposite side of the bending direction of the peeling rod 3. The movement of the slip ring 7 will push away the bellflower root peel stuck on the peeling rod 3, ensuring that a large amount of bellflower root peel will not block the bellflower root and the peeling rod 3 and affect the peeling effect.

[0046] See Figure 4 It also includes multiple protrusions 5, which are spaced along the axial direction of the peeling rod 3 and are formed by each protrusion 5 extending outward from the outer peripheral wall of the peeling rod 3.

[0047] Each protrusion 5 is at least partially provided to correspond to the diagonal brace 6.

[0048] exist Figure 4 From the perspective of the view, it can be seen that multiple protrusions 5 are fixedly installed on the left side of the peeling rod 3. The protrusions 5 are located on the lower surface of the peeling rod 3, so that the protrusions 5 will directly contact the bellflower after the peeling rod 3 reaches the bellflower. The protrusions 5 are fixedly installed on the outer wall of the peeling rod 3 and protrude from the surface of the peeling rod 3. The surface of the peeling rod 3 is smooth, so that the peeling rod 3 will bend directly after contacting the bellflower, and then rub the bellflower skin through the protrusions 5.

[0049] Each protrusion 5 surrounds the peeling rod 3 in a semi-circle and is concentrated on the lower surface of the peeling rod 3. This way, when the left end of the diagonal support 6 and the slip ring 7 move along the peeling rod 3, they can directly scrape the bark on the protrusion 5. The contact points between the protrusion 5 and the bark are relatively concentrated and prominent. When the slip ring 7 slides along the peeling rod 3, the protrusion 5 becomes the main contact point. The thrust of the slip ring 7 can be precisely applied to the bark on the protrusion 5, just like a "hook". The bark is concentrated and hung in a specific position. The slip ring 7 only needs to clean these "hooks" one by one. The target is clear and it is not easy to miss them.

[0050] Meanwhile, the reason why the peeling rod 3 is relatively smooth is that when the peeling rod 3 comes into contact with the protrusion 5, the peeling and friction of the platycodon bark can only be generated by the protrusion 5. The smoothness of the peeling rod 3 results in less friction and smoother sliding of the slip ring 7, making it easier for the platycodon bark to slide down the peeling rod 3 under the action of thrust.

[0051] See Figures 7-9 The protrusion 5 has a cavity inside, and the peeling rod 3 corresponding to the protrusion 5 is provided with an inwardly recessed second deformation groove 9. The second deformation groove 9 is located at the edge end of the outer peripheral wall of the peeling rod 3 and communicates with the cavity. There is a gap between the edge end of the second deformation groove 9 and the contact end of the protrusion 5 and the peeling rod 3.

[0052] As mentioned earlier, the protrusion 5 surrounds half a circle of the peeling rod 3. Therefore, the second deformation groove 9, which is enclosed within the semi-circular protrusion 5, is the same as the protrusion 5. The second deformation groove 9 is formed on the peeling rod 3, also surrounding half a circle of the peeling rod 3 circumferentially. The two ends of the protrusion 5 are closed, and both sides are fixedly connected to the outer wall of the peeling rod 3. Therefore, a cavity is formed inside the protrusion 5. Figure 7 and Figure 8 This is a cross-sectional view of the protrusion 5 and the peeling rod 3, showing that the second deformation groove 9 is connected to the cavity inside the protrusion 5;

[0053] The inner end of the second deformation groove 9 is located deep within the peeling rod 3, while the outer end is located at the edge of the peeling rod 3. When the peeling rod 3 bends, the two outer ends of the second deformation groove 9 will open to the sides, and when the peeling rod 3 straightens, the two outer ends of the second deformation groove 9 will close together. Figure 3 or Figure 4 When the peeling rod 3 bends upward, the upper surface of the peeling rod 3 is the inner side and the lower surface of the peeling rod 3 is the outer side. During the bending process of the peeling rod 3, the material on the outer side will be stretched, generating tensile stress, which is easy to break. The second deformation groove 9 can release this stress. When bending, the force will be concentrated in the second deformation groove 9, and other parts are not easily deformed.

[0054] Multiple second deformation grooves 9 can share this stress together, and at the same time return to Figure 7 and Figure 8 The left and right ends of the protrusion 5 are fixed to the outer ends of the second deformation groove 9. After the peeling rod 3 is bent, the outer ends of the second deformation groove 9 move away from each other, which will pull the two sides of the protrusion 5 away from each other, reducing the protrusion height of the protrusion 5. The protrusion 5 is deformable. After the two sides of the protrusion 5 are stretched, they are in a taut state and store a certain amount of elastic potential energy. At the same time, pay attention to the following. Figure 7 and Figure 8 The edges of the second deformation groove 9 will bend outward due to bending and stretching. The upturned edges will push against the inner wall of the protrusion 5. The upturned edges will press against the inner walls of the two sides of the protrusion 5, preventing the protrusion 5 from being flattened. The protrusion 5 will still protrude from the outer surface of the peeling rod 3, retaining the effect of rubbing the bellflower.

[0055] Meanwhile, during the bending process of the peeling rod 3, the slip ring 7 needs to slide along the peeling rod 3. The protrusion 5 is relatively flattened, which reduces the resistance to the slip ring 7. This allows the slip ring 7 to slide along the peeling rod 3 towards the peeling roller 2 faster and smoother. At the same time, when the two sides of the protrusion 5 are stretched, the protrusion 5 is in a taut state and has a certain elastic potential energy. When the protrusion 5 contacts the surface of the bellflower again, the protrusion 5 will actively stick to the uneven surface of the bellflower by means of elastic potential energy, applying pressure by rigid scraping on one side and elastic rebound force on the other.

[0056] Furthermore, when the protrusion 5 strikes the bellflower quickly, it will slightly "bounce" – meaning it uses elastic potential energy to absorb the impact, like a spring hitting something, where some of the force is "dissipated". The bellflower peel will only sink moderately into the protrusion 5, without getting too stuck. The bellflower peel will be relatively loose, so when the slip ring 7 slides past the protrusion 5, it can more easily push the bellflower peel out.

[0057] See Figures 7-8 The distance between the two sides of the second deformation groove 9 gradually increases outward along the radial direction of the peeling rod 3.

[0058] The inner side of the second deformation groove 9 is narrow and the outer side of the second deformation groove 9 is wide. When the peeling rod 3 is bent, the force will be gradually dispersed along the widened second deformation groove 9. The wide edge of the second deformation groove 9 has high strength and will not be over-deformed, which is equivalent to "setting the boundary" for the bending area to prevent the deformation from spreading to other parts of the peeling rod 3.

[0059] See Figures 7-9 The second deformation groove 9 extends outward from the bottom of the groove to form a protrusion 10. The protrusion 10 protrudes from the outer peripheral wall of the peeling rod 3, and the extended end of the protrusion 10 has a gap with the cavity of the protrusion 5.

[0060] The outer end of the protrusion 10 protrudes beyond the edge of the second deformation groove 9. Figure 7 and Figure 8 As can be seen, the outer end of the protrusion 10 extends into the cavity of the protrusion 5. After the two sides of the protrusion 5 are stretched to both sides, the height of the protrusion 5 will decrease. The protrusion 10 can support the middle part of the protrusion 5 to prevent the center part of the protrusion 5 from collapsing excessively into the second deformation groove 9. At the same time, there is a gap between the inner wall of the protrusion 5 and the outer wall of the protrusion 10, so they will not be in direct contact. In this way, when the two sides of the protrusion 5 are stretched, the gap can provide space for the protrusion height of the protrusion 5 to decrease.

[0061] First combine Figure 5 and Figure 7 In the middle, when the peeling rod 3 deforms and bends upward, the slip ring 7 slides along the peeling rod 3 from left to right. The slip ring 7 first interacts with... Figure 7 The left side of the protrusion 5 abuts, which then pushes the inner wall of the left side of the protrusion 5 to contact the protrusion 10. The tilt angle of the left side of the protrusion 5 then becomes more gradual, which helps the slip ring 7 slide across the left side of the protrusion 5. At this point, it is combined with... Figure 5 and Figure 8 After the tare lever 3 returns to its straight position, the slip ring 7 will slide along the tare lever 3 from right to left, and then the slip ring 7 will... Figure 8 The right side of the protrusion 5 abuts against the protrusion 10, pushing the inner wall of the right side of the protrusion 5 to contact the protrusion 10. Then the right side tilt angle of the protrusion 5 becomes closer to a gentle slope, which helps the slip ring 7 to slide across the right side of the protrusion 5 and push away the bark of the protrusion 5.

[0062] The alternating adjustment of the tilt angles on both sides of protrusion 5 reduces the resistance of protrusion 5 to slip ring 7, thereby reducing the risk of slip ring 7 getting stuck on one side of protrusion 5. Figure 3 and Figure 4 as well as Figure 5 From the perspective of the medium, it is worth adding that the protrusion 5 is a tiny protrusion on the peeling rod 3, which has very little resistance to the slip ring 7 and will not hinder the sliding of the slip ring 7.

[0063] See Figures 3-5The outer peripheral wall of the peeling rod 3 is also provided with a first deformation groove 4. The distance between the two side walls of the first deformation groove 4 gradually increases outward along the radial direction of the peeling rod 3. The first deformation groove 4 is located in the bending direction of the peeling rod 3 and is close to the outer wall of the peeling roller 2.

[0064] When the peeling rod 3 bends upward, the inner walls on both sides of the first deformation groove 4 will come together and close. The first deformation groove 4 is the same as the second deformation groove 9, which can also release the stress of the bending deformation of the peeling rod 3. The first deformation groove 4 also has a wider edge. Because the edges of the first deformation groove 4 are wider, the closing distance is longer, which can increase the upward bending angle of the peeling rod 3. At the same time, when the peeling rod 3 bends upward, the bending point is the first deformation groove 4 near the peeling roller 2, rather than the middle of the peeling rod 3. This allows the free end of the peeling rod 3 to bend upward at a higher angle, and makes the slope of the peeling rod 3 after it is bent smoother, making it easier for the slip ring 7 to slide along the slope of the peeling rod 3 after it is tilted towards the first deformation groove 4.

[0065] Since the right end of the inclined support 6 is hinged to the outer wall of the peeling roller 2, even if the outer wall of the inclined support 6 touches the stem, the left end of the inclined support 6 will be pushed upward due to the force of the contact. As long as the inclined support 6 tilts upward, it will push the peeling rod 3 to tilt upward, and the slip ring 7 will slide along the outer wall of the peeling rod 3.

[0066] See Figures 3-5 The peeling rod 3 is set to gradually narrow along its length at the end away from the peeling roller 2. The narrow end of the peeling rod 3 is fixedly connected with bristles 8, which are elastic and have a smooth outer surface.

[0067] Available to watch Figure 3 In the process of peeling rod 3 approaching the bellflower stem from top to bottom, the bristles 8 will first contact the bellflower stem. Then, under the action of resistance, the bristles 8 and the free end of peeling rod 3 will lift up together. The end of peeling rod 3 away from peeling roller 2 is thinner than the right end and has lower rigidity. When slip ring 7 and the left end of inclined support 6 slide along peeling rod 3, the rigidity of slip ring 7 can be reduced. If both ends of peeling rod 3 are the same thickness, slip ring 7 needs to push away peeling rod 3 with the same rigidity when sliding, which will result in greater resistance and easy jamming.

[0068] See Figures 4-9 The slip ring 7 also includes a sleeve rod 701 and a connecting rope 702. The sleeve rod 701 and the connecting rope 702 are connected end to end to form a slip ring 7 with a complete closed shape.

[0069] The sleeve rod 701 is located between the diagonal brace 6 and the peeling rod 3. One side of the sleeve rod 701 is connected to the diagonal brace 6, and the other side abuts against the peeling rod 3.

[0070] The connecting rope 702 is wound in a spiral shape and is sleeved on the peeling rod 3 and is in close contact with the outer wall of the peeling rod 3.

[0071] The sleeve 701 is located on the lower surface of the peeling rod 3. The outer ring wall of the sleeve 701 is fixedly connected to the outer wall of the inclined support 6. When the slip ring 7 moves, the smooth sleeve 701 is used to contact the outer wall of the protrusion 5 and push away the orange peel stuck on the protrusion 5. When the connecting rope 702 moves, it slides along the upper surface of the peeling rod 3. The connecting rope 702 itself is twisted into a spiral state.

[0072] When the slip ring 7 is at the left end of the peeling rod 3, the connecting rope 702 is in a twisted spiral state. As the connecting rope 702 slides along the outer wall of the peeling rod 3 toward the peeling roller 2, the connecting rope 702 rubs against the peeling rod 3. The direction in which the connecting rope 702 moves to the right is opposite to the direction in which the connecting rope 702 is twisted into a spiral. Therefore, when the connecting rope 702 moves to the right, the friction between the connecting rope 702 and the peeling rod 3 is equivalent to giving the connecting rope 702 a reverse pulling force. Then the spiral of the connecting rope 702 will gradually loosen, making the diameter of the entire slip ring 7 larger to adapt to the shape of the peeling rod 3 gradually thickening from left to right, so that the slip ring 7 will not be too tightly stuck with the peeling rod 3 when it moves to the right.

[0073] This is because after the connecting rope 702 is spirally wound, it will generate a spiral knot in the circumferential direction of the slip ring 7. The tangent direction of each segment of the connecting rope 702 gradually tilts towards the center of the ring, causing the actual effective circumference of the entire slip ring 7 to shorten. When the spiral is released, the spiral structure of the connecting rope 702 gradually unwinds, and the tangent direction of each segment of the connecting rope 702 returns to the circumferential direction of the slip ring 7, which means the ring opening becomes larger.

[0074] according to Figure 3 or Figure 4 From the perspective of the sliding ring 7, when the sliding ring 7 moves to the left, the connecting rope 702 will be re-wound by friction with the outer wall of the peeling rod 3. At this time, the opening of the sliding ring 7 will also shrink, keeping the sliding ring 7 in close contact with the outer wall of the peeling rod 3.
