Description

Technical Field

[0001] This invention belongs to the field of pyrotechnic agent manufacturing technology, specifically relating to an apparatus and method for automated and efficient hole making of thin-walled tubular propellants. Background Technology

[0002] Thin-walled tubular explosives are the core agent carriers of pyrotechnics. The precision and consistency of the perforation of their tube walls directly determine the combustion rate and detonation performance of the explosives, thus affecting the overall reliability and safety of the pyrotechnics. Existing perforation devices for thin-walled tubular explosives mainly require operators to manually place the thin-walled tubular explosives into the perforation device, and then the perforation device operates to perform perforation processing on the thin-walled tubular explosives. Subsequently, operators need to manually adjust the angle and position of the thin-walled tubular explosives so that the perforation device can perform perforation processing at different positions on the thin-walled tubular explosives.

[0003] Existing hole-making devices can reliably perform hole-making on thin-walled tubular drugs, but there are certain problems in actual use. Specifically, the position and angle of the holes and grooves on the thin-walled tubular drugs need to be manually adjusted by the operator, which can easily lead to deviations in the position of the holes and grooves, affecting the overall work quality of the thin-walled tubular drugs. Furthermore, the working efficiency of the hole-making device is directly linked to the operator's experience and physical strength, which affects the overall hole-making efficiency. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] An apparatus and method for automated and efficient hole making of thin-walled tubular drugs includes a frame, a feeding mechanism mounted on the frame for outputting multiple sets of thin-walled tubular drugs one by one, and a conveying mechanism mounted on the frame for receiving and stably conveying the thin-walled tubular drugs output by the feeding mechanism. A punching mechanism for precisely punching the thin-walled tubular drugs is mounted on the upper surface of the frame. The punching mechanism can punch the thin-walled tubular drugs at different angles and positions to ensure the quality of the final product. A grinding mechanism for grinding the inner wall of the punched thin-walled tubular drugs is mounted on the upper surface of the frame and on the side of the punching mechanism. A finished product collection bin is mounted on the side wall of the frame to collect the processed thin-walled tubular drugs. The feeding mechanism, punching mechanism, grinding mechanism and conveying mechanism constitute an automated hole making mechanism, which automatically completes the feeding, hole making, grinding and conveying of the thin-walled tubular drugs.

[0007] As a preferred embodiment of the present invention, the punching mechanism includes a material gripping assembly, a punching assembly, and a chuck rotating component. The material gripping assembly is installed on one side of the upper surface of the frame, and the chuck rotating component is installed on the other side of the upper surface of the frame. A punching assembly for punching thin-walled tubular medicine is installed between the chuck rotating component and the material gripping assembly.

[0008] In a preferred embodiment of the present invention, the punching assembly includes a V-shaped positioning block, an inner liner tube, and a top plate. A V-shaped positioning block is mounted on the upper surface of the frame, supporting the bottom end of the thin-walled tubular drug pushed by the material-grabbing assembly. A top plate is positioned on the frame above the V-shaped positioning block, and a screw drive is mounted below the top plate. A punching cylinder is mounted on the screw drive, driving the punching cylinder to move horizontally. A top seat is mounted at the bottom of the punching cylinder, and a punching head for punching the thin-walled tubular drug is mounted below the top seat. A buffer spring is mounted below the top seat and on the side of the punching head, with a floating pressure block mounted at the end of the buffer spring. The floating pressure block and the V-shaped positioning block are respectively attached to both sides of the outer wall of the thin-walled tubular drug to compress and limit its movement. An inner liner tube, inserted into the inner wall of the thin-walled tubular drug, is provided on the side of the V-shaped positioning block.

[0009] As a preferred embodiment of the present invention, the material gripping assembly includes a material gripping cylinder and a pushing cylinder. The pushing cylinder is installed on the upper surface of the frame, and the output end of the pushing cylinder is equipped with a material gripping cylinder for clamping the thin-walled tubular medicine. The movement of the output end of the pushing cylinder pushes or pulls the position of the thin-walled tubular medicine.

[0010] As a preferred embodiment of the present invention, the chuck rotating component includes a three-jaw chuck, a mounting frame, and a linkage wheel. The mounting frame is mounted on the upper surface of the frame, and the three-jaw chuck for clamping the end of the thin-walled tubular medicine is mounted on the side of the mounting frame. A linkage wheel is mounted on the end of the three-jaw chuck, and a second motor is mounted on the mounting frame. A drive wheel is mounted on the output end of the second motor. The drive wheel and the linkage wheel are both fitted with a linkage wheel. The drive of the second motor has driven the angle of the three-jaw chuck to be adjusted, so that the thin-walled tubular medicine clamped by the three-jaw chuck rotates with a deflection of 36°.

[0011] As a preferred embodiment of the present invention, the grinding mechanism includes a material gripper, a positioning component, and a grinding component. A material gripper is installed on one side of the upper surface of the frame, and the structure of the material gripper is the same as that of the material gripper component. A grinding component is installed on the other side of the upper surface of the frame. A positioning component for clamping thin-walled tubular medicine is installed between the material gripper and the grinding component. The grinding component grinds the inner wall of the thin-walled tubular medicine clamped by the positioning component.

[0012] As a preferred embodiment of the present invention, the polishing assembly includes a first motor, a mounting base, and a brush sleeve. The mounting base is mounted on the upper surface of the frame, and the first motor is mounted on the mounting base. The brush sleeve is installed at the output end of the first motor and is inserted into the thin-walled tubular medicine to polish the inner wall of the thin-walled tubular medicine.

[0013] As a preferred embodiment of the present invention, the positioning component includes a support, a lifting cylinder, and a lower pressure plate. The support is mounted on the frame, a V-shaped locking block is mounted on the top of the support, a lifting cylinder is mounted on the side wall of the support, and a lower pressure plate is mounted on the output end of the lifting cylinder. The lower pressure plate and the V-shaped locking block clamp the side wall of the thin-walled tubular medicine.

[0014] As a preferred embodiment of the present invention, the conveying mechanism includes a support frame, a drive shaft, and a conveyor belt. The support frame is symmetrically mounted on the frame, and the drive shaft is symmetrically rotated and mounted at the end of the support frame. The conveyor belt is externally engaged with the drive shaft, and V-shaped limit blocks are equidistantly mounted on the conveyor belt. The V-shaped limit blocks drive the thin-walled tubular medicine to move stably. A drive motor is mounted on the side wall of the support frame, and the output end of the drive motor is connected to the end of one of the drive shafts.

[0015] A method of using an automated and efficient perforation device for thin-walled tubular drugs includes the following steps:

[0016] A1. Feeding: The operator places the thin-walled tubular medicines to be processed in an orderly manner into the feeding mechanism. The feeding mechanism outputs the thin-walled tubular medicines one by one, allowing them to be received and transported by the conveying mechanism.

[0017] A2. Punching: The conveying mechanism moves the thin-walled tubular medicine to below the punching mechanism. Through the operation of the gripping assembly, the thin-walled tubular medicine on the conveying mechanism is pushed above the V-shaped positioning block. Through the operation of the chuck rotating component, the end of the thin-walled tubular medicine is clamped. Then, under the operation of the punching cylinder, the punching head is driven to punch the thin-walled tubular medicine. The thin-walled tubular medicine that has been punched for the first time rotates at an angle under the operation of the chuck rotating component, which makes it easier for the punching head to punch the outer wall of the thin-walled tubular medicine at multiple angles. The screw drive component can drive the punching head and the punching cylinder to move horizontally, so that the punching head punches the outer wall of the thin-walled tubular medicine at equal intervals on the same axis.

[0018] A3. Grinding: The punched thin-walled tubular medicine re-enters the conveying mechanism, which transports it to the grinding mechanism. The operation of the gripper pushes the punched thin-walled tubular medicine into the positioning component. The punched thin-walled tubular medicine is clamped by the cooperation of the V-shaped locking block and the lower pressure plate. Then, the inner wall of the thin-walled tubular medicine is ground by the rotation of the brush sleeve.

[0019] A4. The collection and conveying mechanism transports the punched and polished thin-walled tubular medicine into the finished product collection bin, completing the hole-making operation of the thin-walled tubular medicine. With the operation of the feeding mechanism, punching mechanism, polishing mechanism and conveying mechanism, the overall processing flow is highly automated to improve the overall working efficiency of the hole-making device.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In this invention, the use of an automated hole-making mechanism enables the entire process of feeding, punching, grinding, and unloading of thin-walled tubular medicines to be fully automated without the need for manual intervention. This greatly accelerates the hole-making speed of a single thin-walled tubular medicine, improves the overall working efficiency of the hole-making device, and eliminates the safety hazards of manual operation.

[0022] The punching mechanism enables precise punching of thin-walled tubular medicines, allowing for precise movement and rotation of the medicines to ensure uniform spacing between holes and grooves, thus guaranteeing the stability of hole making. Furthermore, the subsequent grinding mechanism can grind the inner wall of the punched thin-walled tubular medicines to remove burrs and improve the quality of the finished product.

[0023] The punching and grinding mechanisms both adopt a flexible positioning method of "spring buffer + soft contact" for the contact parts with the thin-walled tubular medicine. In view of the easy deformation characteristics of thin-walled tubes, the positioning pressure is controlled at 0.1-0.4MPa to ensure the drilling accuracy while avoiding damage to the tube wall.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0039] like Figure 1 The diagram shows the structure of the device for automated and efficient perforation of thin-walled tubular drugs in this embodiment. This perforation device can automatically feed and convey thin-walled tubular drugs, and during subsequent punching, it can precisely adjust the position and angle of the drugs, making the spacing and angle of the perforations more accurate. This improves the overall efficiency and quality of the device. The perforation device includes a frame 1, a feeding mechanism 2, and a punching mechanism 3. The feeding mechanism 2 is installed on one side of the frame 1, feeding the thin-walled tubular drugs to be perforated one by one. A conveying mechanism 5 is installed on the upper surface of the frame 1 to convey the thin-walled tubular drugs output by the feeding mechanism 2 one by one. A perforation device is installed on the upper surface of the frame 1 above the conveying mechanism 5 to precisely punch the thin-walled tubular drugs. The punching mechanism 3 is used to make holes, and the angle and position of the thin-walled tubular medicine can be adjusted to make the position of the hole groove on the thin-walled tubular medicine more precise. A grinding mechanism 4 is installed on the upper surface of the frame 1 and on the side of the punching mechanism 3 to grind the inner wall of the thin-walled tubular medicine after hole making. The grinding mechanism 4 removes the burrs on the inner wall of the thin-walled tubular medicine and completes the overall processing of the thin-walled tubular medicine. A finished product collection bin 6 is installed on the side wall of the frame 1 to collect the processed thin-walled tubular medicine. The finished product collection bin 6 is made of non-sparking aluminum alloy. The interior is equipped with three layers of buffer partitions from top to bottom. The surface of the partitions is pasted with silicone pads to prevent sparks or damage when the thin-walled tubular medicine falls. A transparent anti-static observation window is opened on the side of the bin to facilitate the operator to check the finished product inventory in real time. A drawer-type discharge port is set at the bottom of the bin for convenient batch material retrieval.

[0040] In this embodiment, the feeding mechanism 2, punching mechanism 3, grinding mechanism 4 and conveying mechanism 5 constitute an automated hole-making mechanism, which can automatically and efficiently feed, punch and grind thin-walled tubular medicines one by one, thereby improving the overall working quality and efficiency of the hole-making device.

[0041] As attached Figure 2 As shown, this is a schematic diagram of the feeding mechanism 2 in this embodiment. The feeding mechanism 2 includes a stacking bin 21, a guide frame 22, and a blocking block 23. A fixing plate 25 is installed on one side of the upper surface of the frame 1. The stacking bin 21 is located above the fixing plate 25. The stacking bin 21 has a trapezoidal structure and stores the thin-walled tubular medicines to be processed. The operator places multiple sets of thin-walled tubular medicines in the stacking bin 21 in an orderly manner. A guide frame 22 is installed on the side of the stacking bin 21. A conveying trough with a radius equal to that of the thin-walled tubular medicines is opened in the guide frame 22, and the guide frame 22 is connected to the stacking bin 21, allowing the thin-walled tubular medicines stored in the stacking bin 21 to enter the conveying trough one by one. The conveying trough arranges the thin-walled tubular medicines one by one stably. The thin-walled tubular medicines are discharged through the bottom opening of the conveying trough. A blocking block 23 is installed on the upper surface of the fixing plate 25 at the bottom opening of the conveying trough. The stop block 23 limits the thin-walled tubular medicine discharged from the conveying trough. The slope of the stop block 23 limits the position of the thin-walled tubular medicine. The upper surface of the fixing plate 25 is equipped with a feeding cylinder 24 that pushes the thin-walled tubular medicine on the stop block 23. The movement of the output end of the feeding cylinder 24 drives the thin-walled tubular medicine on the surface of the stop block 23 to roll to one side of the conveying mechanism 5, so that the group of thin-walled tubular medicine falls into the conveying mechanism 5, which facilitates the stable output of the subsequent conveying mechanism 5. When the output end of the feeding cylinder 24 pushes the thin-walled tubular medicine, the output end of the feeding cylinder 24 blocks the end opening of the conveying trough. When the output end of the feeding cylinder 24 is reset, the end opening of the conveying trough reopens, and the remaining thin-walled tubular medicine in the conveying trough can continue to be output through the conveying trough, realizing the output of thin-walled tubular medicine one by one.

[0042] As attached Figure 3 As shown, this is a schematic diagram of the punching mechanism 3 in this embodiment. The punching mechanism 3 includes a gripping component 31, a punching component 32, and a chuck rotating component 33. The gripping component 31 is installed on the upper surface of the frame 1 and on one side of the conveying mechanism 5. The chuck rotating component 33 is installed on the upper surface of the frame 1 and on the other side of the conveying mechanism 5. The punching component 32, which performs punching processing on thin-walled tubular medicine, is installed between the gripping component 31 and the punching component 32. The gripping component 31 pushes the thin-walled tubular medicine conveyed on the conveying mechanism 5, allowing the thin-walled tubular medicine to enter the chuck rotating component 33 and be stably clamped by the chuck rotating component 33. This facilitates the subsequent adjustment of the angle of the thin-walled tubular medicine after the initial punching by the chuck rotating component 33, allowing the punching component 32 to perform punching processing on the thin-walled tubular medicine at different angles and positions.

[0043] As attached Figure 4 As shown, this is a schematic diagram of the material gripping assembly 31 in this embodiment. The material gripping assembly 31 includes a material gripping cylinder 311 and a pushing cylinder 312. The pushing cylinder 312 is installed on the upper surface of the frame 1, and the material gripping cylinder 311 is installed at the output end of the pushing cylinder 312. The material gripping cylinder 311 clamps the thin-walled tubular medicine, and the operation of the pushing cylinder 312 pushes the thin-walled tubular medicine clamped by the material gripping cylinder 311, allowing the thin-walled tubular medicine on the conveying mechanism 5 to enter the punching assembly 32 and the chuck rotating part 33 on the side, so that the punching assembly 32 can punch the thin-walled tubular medicine. After punching, the thin-walled tubular medicine is moved back to the conveying mechanism 5 by the clamping of the material gripping cylinder 311 and the pulling of the pushing cylinder 312, so that the conveying mechanism 5 can transport the punched thin-walled tubular medicine. It is worth noting that the grippers of the material gripping cylinder 311 are wrapped with anti-static silicone pads to prevent damage to the outer wall of the thin-walled tubular medicine.

[0044] As attached Figure 5 As shown, this is a schematic diagram of the punching assembly 32 in this embodiment. The punching assembly 32 includes a V-shaped positioning block 321 and an inner liner tube 322. The V-shaped positioning block 321 is installed on the upper surface of the frame 1 and between the material gripping assembly 31 and the punching assembly 32. A top plate 323 is provided on the frame 1 above the V-shaped positioning block 321. An inner liner tube 322, which is inserted into the thin-walled tubular medicine, is installed on the side of the V-shaped positioning block 321. The inner liner tube 322 is positioned by the use of the chuck rotating component 33. A screw drive component 324 is installed below the top plate 323. The screw drive component 324 adopts the existing screw drive mechanism, which is prior art and will not be described in detail. A punching cylinder 325 is installed on the moving end of the screw drive mechanism. A top seat 326 is installed on the output end of the punching cylinder 325. Punching heads 327 for punching thin-walled tubular medicine are symmetrically installed on the bottom end of the top seat 326. A buffer spring 328 is installed below the punch head 327 on the side. A floating pressure block 329 is installed at the end of the buffer spring 328. As the output end of the punch cylinder 325 moves, the top seat 326 is in a vertical lifting state. The top seat 326 pushes the punch head 327 and the floating pressure block 329 to move closer to the thin-walled tubular drug. The floating pressure block 329 first contacts the thin-walled tubular drug. Utilizing the elasticity and retractable characteristics of the buffer spring 328, the floating pressure block 329 and the V-shaped positioning block 321 accurately clamp and position the thin-walled tubular drug. As the punch head 327 continues to move, it punches holes in the thin-walled tubular drug. After the initial punching of the thin-walled tubular drug is completed, the horizontal position of the punch head 327 and the punch cylinder 325 is adjusted by the operation of the screw drive 324, so that the punch head 327 performs equidistant perforation at different positions on the same axis of the thin-walled tubular drug.

[0045] As attached Figure 6 As shown, this is a schematic diagram of the chuck rotating component 33 in this embodiment. The chuck rotating component 33 includes a three-jaw chuck 331, a mounting frame 332, and a linkage wheel 333. The mounting frame 332 is mounted on one side of the upper surface of the frame 1, and the three-jaw chuck 331 is mounted on the mounting frame 332. The three-jaw chuck 331 clamps the inner liner tube 322 and the end of the thin-walled tubular drug, thereby locking the position of the thin-walled tubular drug and facilitating the punching assembly 32 to perform precise punching on the thin-walled tubular drug. A second motor 334 is mounted on the mounting frame 332. The output end of the second motor 334 is equipped with a drive wheel 335, and the end of the three-jaw chuck 331 is equipped with a linkage wheel 333. The linkage wheel 333 and the drive wheel 335 are connected by a synchronous belt 336. Driven by the second motor 334, the drive wheel 335 drives the linkage wheel 333 to adjust the angle. At this time, the three-jaw chuck 331 drives the clamped thin-walled tubular medicine to rotate, so that the angle of the thin-walled tubular medicine is deflected to one side by 36°, so that the punching assembly 32 punches holes on the side wall of the thin-walled tubular medicine at different angles.

[0046] As attached Figure 7 As shown, this is a schematic diagram of the grinding mechanism 4 in this embodiment. The grinding mechanism 4 includes a gripping component 41, a positioning component 42, and a grinding component 43. The gripping component 41 is installed on one side of the upper surface of the frame 1, and the grinding component 43 is installed on the other side of the upper surface of the frame 1. The positioning component 42 is installed between the gripping component 41 and the grinding component 43. The overall structure of the gripping component 41 is the same as that of the gripping component 31. The gripping component 41 pushes and clamps the thin-walled tubular medicine punched by the conveying mechanism 5, so that the thin-walled tubular medicine is detached from the conveying mechanism 5 and docked with the grinding component 43. The positioning component 42 locks the position of the thin-walled tubular medicine pushed by the gripping component 41, so that the grinding component 43 can grind the inner wall of the thin-walled tubular medicine in the future.

[0047] As attached Figure 8 As shown, this is a schematic diagram of the positioning component 42 in this embodiment. The positioning component 42 includes a support 421, a lifting cylinder 422, and a lower pressure plate 423. The support 421 is installed on the upper surface of the frame 1. A V-shaped locking block 424 is installed on the support 421. The V-shaped locking block 424 limits the position of the thin-walled tubular medicine. The lifting cylinder 422 is installed on the side wall of the support 421. The lower pressure plate 423 is installed at the output end of the lifting cylinder 422. The movement of the output end of the lifting cylinder 422 drives the lower pressure plate 423 to move up and down synchronously, so that the lower pressure plate 423 makes pressure contact with the outer wall of the thin-walled tubular medicine. With the cooperation of the lower pressure plate 423 and the V-shaped locking block 424, the position of the thin-walled tubular medicine is clamped and locked, which facilitates the subsequent grinding component 43 to grind the inner wall of the thin-walled tubular medicine.

[0048] It is worth noting that the lower surface of the pressure plate 423 in this embodiment is provided with an antistatic rubber layer, and the brush sleeve 433 is made of carbon fiber antistatic material, which can efficiently remove burrs from the inner wall of the thin-walled tubular medicine without damaging the inner wall of the thin-walled tubular medicine, thus ensuring the stability of the overall processing.

[0049] As attached Figure 7 As shown, this is a schematic diagram of the structure of the polishing component 43 in this embodiment. The polishing component 43 includes a first motor 431, a mounting base 432, and a brush sleeve 433. The mounting base 432 is installed on the upper surface of the frame 1, and the first motor 431 is installed at the top of the mounting base 432. The brush sleeve 433 is installed on the first motor 431. When the material gripper 41 pushes the thin-walled tubular medicine from the conveying mechanism 5 onto the V-shaped locking block 424, the brush sleeve 433 is inserted into the inner wall of the thin-walled tubular medicine. Through the operation of the first motor 431, the brush sleeve 433 rotates as a whole, polishing the inner wall of the thin-walled tubular medicine.

[0050] As attached Figure 9 As shown, this is a schematic diagram of the conveying mechanism 5 in this embodiment. The conveying mechanism 5 includes a support bracket 51, a drive shaft 52, and a conveyor belt 53. The support bracket 51 is symmetrically installed on the upper surface of the frame 1. The drive shaft 52 is symmetrically installed at both ends of the support bracket 51. The conveyor belt 53 is meshed with the outside of the drive shaft 52. V-shaped limiting blocks 54 that drive the thin-walled tubular medicine to move stably are installed at equal intervals on the upper surface of the conveyor belt 53. A drive motor 55 is installed on the side wall of the support bracket 51. The drive motor 55 drives the drive shaft 52 to rotate. Under the transmission of the conveyor belt 53, the V-shaped limiting blocks 54 drive the thin-walled tubular medicine to move stably. It is worth noting that the surface of the conveyor belt 53 in this embodiment is coated with an antistatic coating, and the V-shaped limiting blocks 54 are made of aluminum profiles. The inner wall of the V-shaped limiting blocks 54 is bonded with a soft buffer pad to support the thin-walled tubular medicine and restrict its radial movement to prevent collisions during transportation.

[0051] A method of using an automated and efficient perforation device for thin-walled tubular drugs includes the following steps:

[0052] A1. Feeding: The operator places the thin-walled tubular medicines to be processed in an orderly manner into the feeding mechanism 2. The feeding mechanism 2 outputs the thin-walled tubular medicines one by one, allowing the thin-walled tubular medicines to be received and transported by the conveying mechanism 5.

[0053] A2. Punching: The conveying mechanism 5 moves the thin-walled tubular medicine to below the punching mechanism 3. Through the operation of the gripping assembly 31, the thin-walled tubular medicine on the conveying mechanism 5 is pushed above the V-shaped positioning block 321. Through the operation of the chuck rotating part 33, the end of the thin-walled tubular medicine is clamped. Then, under the operation of the punching cylinder 325, the punching head 327 is driven to punch the thin-walled tubular medicine. The thin-walled tubular medicine that has been punched for the first time rotates at an angle under the operation of the chuck rotating part 33, which makes it easier for the punching head 327 to punch the outer wall of the thin-walled tubular medicine at multiple angles. The screw drive part 324 can drive the punching head 327 and the punching cylinder 325 to move horizontally, so that the punching head 327 punches the outer wall of the thin-walled tubular medicine at equal intervals on the same axis.

[0054] A3. After grinding and punching, the thin-walled tubular medicine is reintroduced onto the conveying mechanism 5, which transports it to the grinding mechanism 4. The operation of the gripping component 41 pushes the punched thin-walled tubular medicine into the positioning component 42. The punched thin-walled tubular medicine is clamped by the cooperation of the V-shaped locking block 424 and the lower pressure plate 423. Then, the inner wall of the thin-walled tubular medicine is ground by the rotation of the brush sleeve 433.
