Description

Technical Field

[0001] This utility model belongs to the field of Magnolia officinalis processing technology, and in particular, it is a processing device for removing the rough bark of Magnolia officinalis. Background Technology

[0002] Magnolia officinalis is the dried bark, root bark, and branch bark of Magnolia officinalis or Magnolia davidii, both belonging to the Magnoliaceae family. It is harvested from April to June. The root bark and branch bark are directly air-dried. The dried bark is briefly boiled in boiling water, then piled in a damp, shady place to sweat until the inner surface turns purplish-brown or brownish-red. It is then steamed until soft, removed, rolled into a tube, and dried. Before using Magnolia officinalis in medicine, the rough outer bark needs to be removed. Chinese Patent No. CN216019004U discloses "A self-resetting and adjusting device for the bottom plate of a machine for removing rough bark from bark-type Chinese medicinal materials, including a frame, a mounting frame, and a belt conveyor mechanism. A pressure roller and several steel wire brushes are rotatably mounted on the mounting frame. There is a gap between the lower edge of the pressure roller and the steel wire brushes and the upper surface of the upper belt of the belt conveyor mechanism for the passage of Chinese medicinal materials. A bottom plate is provided below the upper belt of the belt conveyor mechanism to support the belt." Both the front and rear ends are mounted on the frame via self-resetting deflection mechanisms. The base plate can move downwards under pressure and automatically reset. This utility model has a simple structure and can adaptively adjust the height of the gap according to the different thicknesses of Chinese medicinal materials, ensuring that Chinese medicinal materials of different thicknesses can pass smoothly through the gap for rough skin removal without manual adjustment, saving time and labor costs and improving work efficiency. Existing technology uses a self-resetting deflection mechanism to solve the problem of Chinese medicinal materials of different thicknesses passing smoothly through the gap between the belt, pressure roller, and several roller wire brushes. However, because the self-resetting deflection mechanism is located below the belt, corresponding to the position between the pressure roller and several roller wire brushes, when the belt is pressed down, the belt tensions, resulting in excessive friction between the belt and the drive roller shafts at both ends. This easily leads to belt wear and transmission obstruction, which is not conducive to long-term use. Utility Model Content

[0003] The purpose of this utility model is to provide a processing device for removing the rough bark of Magnolia officinalis, in order to solve the problem in the prior art where the self-resetting deflection mechanism is located below the belt, corresponding to the position between the pressure roller and several roller wire brushes. When the belt is pressed down, the belt is tensioned, resulting in excessive friction between the belt and the transmission roller shafts at both ends, which easily leads to belt wear and transmission obstruction, and is not conducive to long-term use.

[0004] Technical solution:

[0005] A processing apparatus for removing the rough bark of Magnolia officinalis includes a transmission mechanism mounted on a frame. A mounting frame is provided on the frame above the transmission mechanism. The transmission mechanism includes a power component and a belt connected to the power component. The power component is mounted on the frame to drive the belt drive. A self-resetting deflection mechanism for supporting the belt is provided on the inner side of the belt above the frame. The self-resetting deflection mechanism includes a base plate and a self-resetting deflection assembly connected between the base plate and the frame. The power component includes two transmission rollers rotatably mounted at both ends of the frame. The belt surrounds the two transmission rollers. An elastic fitting mechanism is provided between the transmission rollers and the belt. The elastic fitting mechanism drives the belt drive as the transmission rollers rotate.

[0006] The elastic adapter mechanism includes several elastic adapter components, which are arranged at equal intervals around the outside of the transmission roller shaft with the center of the transmission roller shaft as the center. Each elastic adapter component includes an auxiliary roller shaft, which is rotatably mounted on a support. The support is detachably connected to the elastic component mounted on the transmission roller shaft. The inner wall of the belt rolls against the several auxiliary roller shafts.

[0007] In a further embodiment, a pressure roller and a plurality of roller wire brushes are sequentially rotatably mounted on the mounting frame along the conveying direction of the belt, and there is a gap between the lower edge of the pressure roller and the plurality of roller wire brushes and the upper surface of the upper belt of the frame for thick metal to pass through.

[0008] In a further embodiment, the self-resetting deflection assembly includes four connecting plates, all of which are inclined toward the discharge end of the belt. One end of each of the four connecting plates is rotatably connected to the front and rear sides of the base plate, and the other end of each of the four connecting plates is rotatably connected to the sides of the frame. The base plate, the two connecting plates on the same side, and the frame form a parallelogram telescopic structure.

[0009] Each of the connecting plates on the frame is provided with a column on the side away from the conveyor belt discharge end, and a tension spring is connected between the corresponding connecting plate and the column.

[0010] In a further embodiment, both ends of the auxiliary roller are fixed with rotating shafts, and the rotating shafts are rotatably connected to the bracket via bearings;

[0011] The bracket has a "T" shaped structure. The bracket includes a horizontal part and a vertical part that is vertically fixed at the lower center position of the horizontal part. The horizontal part is connected to the rotating shaft, and the vertical part is detachably connected to the elastic component.

[0012] In a further embodiment, the bearing is a one-way bearing, and the rotation direction of the shaft in the bearing is consistent with the rotation direction of the transmission roller shaft.

[0013] In a further embodiment, the elastic component includes a support block, the bottom of which extends into a telescopic groove, the telescopic groove being formed in the radial direction of the transmission roller shaft, and an installation groove being formed on the top of the support block outside the telescopic groove, the installation groove cooperating with the vertical part for insertion, the vertical part being inserted into the installation groove and the vertical part being fixed to the support block using bolt locking components;

[0014] The telescopic groove is provided with a first support spring. The two ends of the first support spring abut against the bottom of the support block and the bottom of the telescopic groove, respectively. As the first support spring extends and retracts, the support block slides in the telescopic groove along the depth direction of the telescopic groove.

[0015] In a further embodiment, a stabilizing component is provided between the transverse portion and the transmission roller shaft. The stabilizing component includes two vertical rods symmetrically arranged about the vertical center line of the transverse portion. The bottom of the vertical rods is fixed to the transmission roller shaft, and the top of the vertical rods is fixed to a limit block.

[0016] A positioning block is slidably sleeved on the vertical rod, and a second support spring is connected between the positioning block and the surface of the transmission roller shaft. The second support spring is sleeved on the outside of the vertical rod.

[0017] The positioning block is detachably connected to the vertical part via a connector. The connector includes an insert fixed on the positioning block. The insert is inserted into a socket. The socket is located on the horizontal part. The limiting block and the second support spring are located at the upper and lower ends of the positioning block, respectively.

[0018] The beneficial effects of this utility model are as follows: By setting several elastic adapter components between the transmission roller shaft and the belt, when the thick pad passes between the belt and the pressure roller and the wire brush, the belt is pressed down. At this time, the two ends of the belt are also squeezed by the elastic adapter components. The elastic adapter components include auxiliary roller shafts, which roll in contact with the belt and can elastically extend and retract. Unlike the existing technology where the belt directly contacts the transmission roller shaft for transmission, the setting of the elastic adapter components in this solution can avoid the belt being too tense and the friction between it and the transmission roller shaft increasing, which would lead to belt wear or even breakage. It effectively protects the belt without affecting the belt transmission. At the same time, the auxiliary roller shafts can be easily disassembled and assembled, which is beneficial for maintaining the auxiliary roller shafts at the corresponding positions according to the actual use.

Detailed Implementation

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1-4This utility model discloses a processing device for removing the rough bark of Magnolia officinalis, including a transmission mechanism 1 mounted on a frame 2. A mounting frame 31 is provided on the frame 2 above the transmission mechanism 1. The transmission mechanism 1 includes a power component 11 and a belt 13 connected to the power component 11. The power component 11, mounted on the frame 2, drives the belt 13. A self-resetting deflection mechanism 4 is provided on the inner side of the belt 13 above the frame 2 to support the belt 13. The self-resetting deflection mechanism 4 includes a base plate 41 and a self-resetting deflection assembly connected between the base plate 41 and the frame 2. The power component 11 includes two transmission rollers 12 rotatably mounted at both ends of the frame 2. The belt 13 surrounds the two transmission rollers 12. An elastic fitting mechanism 5 is provided between the transmission rollers 12 and the belt 13. The elastic fitting mechanism 5 moves with the transmission... The rotation of the roller 12 drives the belt 13 for transmission. Both ends of the transmission roller 12 are rotatably connected to the frame 2. A power motor is provided on or outside the frame 2. The power motor drives the transmission roller 12 to rotate directly or indirectly. Directly, the output end of the power motor is connected to the transmission roller 12. Indirectly, the output end of the power motor is connected to the transmission roller 12 through transmission gears or other transmission components. The elastic adaptation mechanism 5 includes several elastic adaptation components 6. The several elastic adaptation components 6 are arranged at equal intervals around the outside of the transmission roller 12 with the center of the transmission roller 12 as the center. The elastic adaptation component 6 includes an auxiliary roller 61. The auxiliary roller 61 is rotatably mounted on a bracket 62. The bracket 62 is detachably connected to the elastic component 7 provided on the transmission roller 12. The inner wall of the belt 13 rolls against the several auxiliary rollers 61. The axis of the auxiliary roller 61 is parallel to the axis of the transmission roller 12.

[0027] The mounting frame 31 is rotatably mounted with a pressure roller 33 and several roller wire brushes 32 along the conveying direction of the belt 13. There is a gap between the lower edge of the pressure roller 33 and the roller wire brushes 32 and the upper surface of the belt 13 on the upper part of the frame 2 for the passage of Magnolia officinalis. The bottom plate 41 is located below the pressure roller 33 and the roller wire brushes 32. When Magnolia officinalis and other Chinese medicinal materials pass through the gap, the pressure roller 33 and the roller wire brushes 32 press down on the medicinal materials and the belt 13, thereby causing the bottom plate 41 to be squeezed and moved downward.

[0028] The self-resetting deflection assembly includes four connecting plates 42, all of which are inclined toward the discharge end of the belt 13. One end of each connecting plate 42 is rotatably connected to the front and rear ends of the base plate 41, respectively, and the other end is rotatably connected to the sides of the frame 2, respectively. The base plate 41, the two connecting plates 42 on the same side, and the frame 2 form a parallelogram telescopic structure. A column 43 is provided on the frame 2 on the side of each connecting plate 42 away from the discharge end of the belt 13, corresponding to the connecting plate... A tension spring 44 connects 42 to the column 43. The column 43 is a stud, and the other end of the tension spring 44 is hooked onto the stud. A nut is screwed onto the stud to limit the other end of the tension spring 44. When a Chinese medicinal material such as Magnolia officinalis with a thickness greater than the gap height passes through the gap, the base plate 41 is squeezed and moves downward. All four connecting plates 42 flip downward, and the tension spring 44 is stretched, which increases the adaptability of the gap height. After the Chinese medicinal material such as Magnolia officinalis with a thickness greater than the gap height passes through the gap, the tension spring 44 retracts and resets, and all four connecting plates 42 flip upward and reset, driving the base plate 41 to move upward and reset.

[0029] Both ends of the auxiliary roller 61 are fixed with rotating shafts, which are rotatably connected to the bracket 62 via bearings 611. The bracket 62 has a "T" shaped structure and includes a horizontal part and a vertical part that is vertically fixed at the lower center of the horizontal part. The horizontal part is connected to the rotating shaft, and the vertical part is detachably connected to the elastic component 7. There are also two brackets 62, located at both ends of the auxiliary roller 61. The sum of the lengths of the auxiliary roller 61 and the brackets 62 matches the length of the transmission roller 12.

[0030] The bearing 611 is a one-way bearing 611. The rotation direction of the shaft in the bearing 611 is the same as the rotation direction of the transmission roller shaft 12. When the transmission roller shaft 12 rotates, several auxiliary roller shafts 61 also rotate. In order to further stabilize the transmission direction and transmission stability of the belt 13, the one-way bearing 611 ensures that the belt 13 will not reverse transmission when it rolls into contact with the auxiliary roller shafts 61.

[0031] The elastic component 7 includes a support block 71, the bottom of which extends into a telescopic groove 72. The telescopic groove 72 is formed in the radial direction of the transmission roller shaft 12. A mounting groove 711 is formed on the top of the support block 71 outside the telescopic groove 72. The mounting groove 711 is used to insert the vertical part. The vertical part is inserted into the mounting groove 711 and secured to the support block 71 using bolts. A first support spring 73 is provided inside the telescopic groove 72, and both ends of the first support spring 73 are respectively connected to the support block 71. The bottom of the support block 71 abuts against the bottom of the telescopic groove 72. As the first support spring 73 extends and retracts, the support block 71 slides along the depth direction of the telescopic groove 72. When the middle part of the belt 13 in contact with the bottom plate 41 is pressed down, the two ends of the belt 13 also exert pressure on the auxiliary roller shaft 61. At this time, the auxiliary roller shaft 61 is also under pressure and approaches the transmission roller shaft 12. At this time, the support block 71 compresses the first support spring 73 and extends into the telescopic groove 72 to avoid severe uneven force on the end of the belt 13.

[0032] A stabilizing component 8 is also provided between the transverse section and the transmission roller shaft 12. The stabilizing component 8 includes two vertical rods 81 symmetrically arranged about the vertical center line of the transverse section. The bottom of the vertical rods 81 is fixed to the transmission roller shaft 12, and the top is fixed with a limit block. A positioning block 82 is slidably sleeved on the vertical rod 81. A second support spring 83 is connected between the positioning block 82 and the surface of the transmission roller shaft 12. The second support spring 83 is sleeved on the outside of the vertical rod 81. The positioning block 82 is detachably connected to the vertical section by a connector, which includes a component fixed to the vertical section. The insertion block on the positioning block 82 is inserted into the insertion hole, which is opened on the horizontal part. The limiting block and the second support spring 83 are located at the upper and lower ends of the positioning block 82, respectively. When the vertical part is inserted into the mounting groove 711, the horizontal part rests on the positioning block 82 through the cooperation of the insertion block in the insertion hole. Then, the vertical part and the support block 71 are locked with a locking member. When the auxiliary pressure roller 33 is stretched and extended by force, the positioning block 82 also slides on the vertical rod 81. At this time, the second support spring 83 also stretches and extends in coordination. The arrangement of the first support spring 73 and the second support spring 83 can ensure good support.

[0033] The implementation principle of this utility model is as follows: When a Chinese medicinal material such as Magnolia officinalis with a thickness greater than the gap height passes through the gap, the bottom plate 41 is squeezed and moves downward, and the four connecting plates 42 are all flipped downward. The tension spring 44 is stretched, which increases the adaptability of the gap height. At the same time, the belt 13 at the gap position is squeezed, and the two ends of the belt 13 also squeeze the auxiliary roller shaft 61. The first support spring 73 and the second support spring 83 are compressed in cooperation. When the Chinese medicinal material such as Magnolia officinalis with a thickness greater than the gap height passes through the gap, the tension spring 44 retracts and resets, and the four connecting plates 42 are all flipped upward and reset, driving the bottom plate 41 to move upward and reset. The belt 13 at the gap position is not under pressure, and the two ends of it will not squeeze the auxiliary roller shaft 61. The first support spring 73 and the second support spring 83 can then reset.
