Description

Technical Field

[0001] The present application belongs to the technical field of drug column preparation, and specifically relates to a punching and trimming structure and a punching and trimming device. Background Art

[0002] During the manufacturing process, in order to ensure that the final product can form a complete coated grain, the grain body is designed with a central hole. After the coating is pasted on the end face, the center hole of the coating needs to be punched out to make it completely consistent with the center hole of the grain body. Therefore, in order to achieve this goal, the grain must be trimmed and punched. This process involves precise shearing and punching technology to ensure that the coating fits perfectly with the grain body. In this way, the overall structure of the grain can be ensured to be stable while meeting the design requirements, and finally a structurally complete and fully functional coated grain is formed.

[0003] The common grain punching and trimming machines on the market usually process the punching and trimming processes separately during the grain processing. The reason for this operation mode is that the existing machine design simply combines the punching and trimming mechanisms without deeper integration. Therefore, this simple combination mode forces the machine to separate the punching and trimming into two independent steps in actual operation. This not only increases the processing time, but also reduces the efficiency of the entire production process to a certain extent. Summary of the invention

[0054] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0055] See also Figure 1-7 As shown, according to an embodiment of the present application, a punching and trimming structure is provided, comprising:

[0056] A first driving unit 1;

[0057] An inner rotary cover 2, a telescopic member 3 is arranged between a first end of the inner rotary cover 2 and an output end of the first driving part 1, and a first blade 4 is arranged on a second end of the inner rotary cover 2;

[0058] An outer cover 5 is concentrically arranged outside the inner cover 2, a plurality of transmission members 6 are arranged between the outer cover 5 and the inner cover 2, and a second blade 7 is arranged on the outer cover 5;

[0059] A second driving part 8, which is disposed on the outer rotating cover 5, and can drive the second blade 7 to move radially;

[0060] The telescopic member 3 can drive the inner rotary cover 2 and the outer rotary cover 5 to move radially. When the inner rotary cover 2 and the outer rotary cover 5 are in contact with the object to be cut, the telescopic member 3 can drive the inner rotary cover 2 to move radially relative to the outer rotary cover 5 .

[0061] In the punching and trimming structure provided in this embodiment, the first driving part 1 serves as the power source of the entire structure and provides the initial power for the movement of the inner rotating cap 2. It usually adopts a high-precision, high-torque motor that can accurately control the output speed and torque to ensure that the movement of the inner rotating cap 2 is stable and meets the processing requirements. A telescopic member 3 is arranged between the output end of the first driving part 1 and the first end of the inner rotating cap 2. The telescopic member 3 can not only transmit the power of the first driving part 1 in the axial direction to make the inner rotating cap 2 move axially, but also adjust the position of the inner rotating cap 2 according to the actual processing situation to achieve contact between the inner rotating cap 2 and the object to be cut.

[0062] The first blade 4 provided on the second end of the inner rotating cap 2 is used for drilling. The shape, material and cutting edge design of the first blade 4 are carefully optimized to meet the drilling requirements of the coating layer on the end of the drug column. The material is usually a high-strength, high-hardness alloy material, which can remain sharp during high-speed rotation and downward pressure, and effectively penetrate the coating layer of the drug column.

[0063] The outer rotating cover 5 is concentrically arranged on the outside of the inner rotating cover 2, and the two are connected by a plurality of transmission members 6. The transmission member 6 can transmit the rotational motion of the inner rotating cover 2 to the outer rotating cover 5, which is the basis for the trimming and punching operations. The second blade 7 arranged on the outer rotating cover 5 is used for trimming operations, and can accurately trim the edge of the coating layer on the end surface of the drug column. The second driving unit 8 is arranged on the outer rotating cover 5, which provides power for the radial movement of the second blade 7, so that the second blade 7 can perform trimming operations on the object to be cut at different radial positions to meet the processing requirements of drug columns of different sizes.

[0064] In the actual working process, after starting the equipment, the inner rotating cap 2 and the outer rotating cap 5 are driven by the telescopic member 3 to approach the medicine column to be cut. When the inner rotating cap 2 and the outer rotating cap 5 are in contact with the coating layer of the object to be cut, the second driving part 8 drives the second blade 7 to move radially as needed, so that the second blade 7 can trim the coating layer of the medicine column until it contacts the medicine column shell. At the same time, the telescopic member 3 can further drive the inner rotating cap 2 to move radially relative to the outer rotating cap 5, so that the first blade 4 contacts the coating layer of the medicine column, and continues to press down, so that the first blade 4 can perform the punching operation. This structure organically combines the two processes of punching and trimming, greatly reduces the processing time, improves the efficiency of the entire production process, and avoids the problems caused by the existing machines operating the two processes separately.

[0065] Furthermore, the object to be cut is the coating layer of a drug column.

[0066] The telescopic member 3 comprises:

[0067] A first telescopic rod 31, a first end of the first telescopic rod 31 is connected to an output end of the first driving part 1;

[0068] A second telescopic rod 32, wherein a first end of the second telescopic rod 32 is provided with a mounting groove, a second end of the first telescopic rod 31 is slidably disposed in the mounting groove, and a second end of the second telescopic rod 32 is connected to a first end of the inner rotating cover 2;

[0069] The first driving member 33 is disposed on the first telescopic rod 31 , and an output end of the first driving member 33 is connected to a first end of the inner rotating cover 2 .

[0070] In this technical solution, the first telescopic rod 31 is connected to the output end of the first driving part 1, and is usually made of high-strength metal material with good rigidity and strength to withstand the force and torque transmitted during the working process. The installation groove opened at the first end of the second telescopic rod 32 and the sliding cooperation of the second end of the first telescopic rod 31 are used to achieve flexible telescopic. This sliding setting mode enables the first telescopic rod 31 to move smoothly in the installation groove, thereby changing the length of the entire telescopic member 3. The second end of the second telescopic rod 32 is connected to the first end of the inner rotating cover 2, transmitting the telescopic motion to the inner rotating cover 2, thereby realizing the position adjustment of the inner rotating cover 2 in the axial direction.

[0071] The first driving member 33 is arranged on the first telescopic rod 31, and its output end is connected to the first end of the inner rotating cap 2. The first driving member 33 can be a small electric push rod, a hydraulic push rod or other suitable driving device. During operation, the first driving member 33 works in coordination with the first driving part 1. When the first driving part 1 drives the first telescopic rod 31 to move, the first driving member 33 can apply additional thrust or pulling force to the inner rotating cap 2 as needed to control the position and movement state of the inner rotating cap 2. For example, when it is necessary to fine-tune the inner rotating cap 2 to better adapt to the different sizes or shapes of the drug column, the first driving member 33 can play an important role in ensuring that the first blade 4 can accurately perform a punching operation on the coating layer of the drug column end surface, while ensuring the stability and accuracy of the entire punching and trimming process.

[0072] The transmission member 6 comprises:

[0073] A first elastic member 61, a groove is formed on the inner circumference of the outer rotating cover 5, and a first end of the first elastic member 61 is connected to the groove;

[0074] The movable plate 62, the second end of the first elastic member 61 is connected to the movable plate 62;

[0075] The protrusion 63 is provided with a slide groove on the outer circumference of the inner rotary cover 2. The protrusion 63 is connected to the end of the movable plate 62 away from the first elastic member 61, and the protrusion 63 is arranged in the slide groove.

[0076] In this technical solution, the first elastic member 61 and the movable plate 62 are located in the groove of the inner circumference of the outer rotating cover 5. When subjected to external force, the first elastic member 61 can produce elastic deformation within a certain range, and store and release energy during the deformation process. It is used to ensure that the outer rotating cover 5 and the inner rotating cover 2 can be stably connected during the entire working process. The protrusion 63 is located in the slide groove of the outer circumference of the inner rotating cover 2. The protrusion 63 is connected to the end of the movable plate 62 away from the first elastic member 61. This connection method ensures that the movement of the inner rotating cover 2 can be transmitted to the inner rotating cover 2 through the protrusion 63 and the movable plate 62. This transmission method can not only ensure the synchronous rotation between the outer rotating cover 5 and the inner rotating cover 2, but also can adapt to the slight displacement and deformation that may occur during the processing process to a certain extent, ensuring the stability and accuracy of the punching and trimming operations. At the same time, the elastic effect of the first elastic member 61 can also play a buffering effect during the movement, reduce the damage to the inner rotating cover 2 and the outer rotating cover 5 caused by impact or vibration, and extend the service life of the entire punching and trimming structure.

[0077] The transmission member 6 also includes a connecting member 64, and the connecting member 64 includes:

[0078] A first baffle 641, wherein a first end of the first baffle 641 is connected to the movable plate 62, and a stopper 642 is disposed on a second end of the first baffle 641;

[0079] A second baffle 643, wherein a first end of the second baffle 643 is provided with an arc-shaped groove matching the baffle 642, and a second end of the second baffle 643 is connected to the protrusion 63;

[0080] A rotating shaft 644 and a torsion spring 645 are disposed between the second end of the first baffle 641 and the first end of the second baffle 643 .

[0081] The groove includes a straight end and an inclined section.

[0082] In this technical solution, when the outer rotating cover 5 starts to rotate and generates a movement trend, the first elastic member 61 will respond accordingly according to the shape of the groove. At the straight end portion, the first elastic member 61 maintains a relatively stable state, and the movable plate 62 and the first baffle 641 connected thereto are also in a stable position to avoid malfunction due to slight disturbance.

[0083] However, when the movement is transmitted to the inclined section of the groove, the situation changes. The existence of the inclined section changes the force direction of the first elastic member 61, causing it to begin to deform, thereby pushing the movable plate 62 to move. The movement of the movable plate 62 drives the first baffle 641 to move. Since the first baffle 641 and the second baffle 643 are connected by the rotating shaft 644 and the torsion spring 645, the movement of the first baffle 641 causes the block 642 to slide relative to each other in the arc groove. This relative sliding, under the action of the torsion spring 645, will generate a restoring force related to the direction of movement. This restoring force and the elastic force of the first elastic member 61 work together to accurately control the movement of the protrusion 63 in the slide groove.

[0084] During the punching operation, as the outer rotating cover 5 rotates and the inclined section of the groove guides the transmission, the inner rotating cover 2 achieves precise coordination with the movement of the first blade 4 through the orderly movement of the protrusion 63 in the slide groove and the coordinated action of the connector 64. In this process, the first blade 4 can punch holes in the coating layer on the end of the medicine column at the optimal angle and force, reducing errors in the punching process and unnecessary damage to the medicine column. During the trimming operation, the same principle enables the relative position between the outer rotating cover 5 and the inner rotating cover 2 to be dynamically adjusted, ensuring good contact between the second blade 7 and the first blade 4 and the edge of the coating layer on the end of the medicine column, effectively controlling the precision and quality of trimming, and reducing the flash phenomenon, thereby making the entire punching and trimming process more efficient and accurate.

[0085] The second driving unit 8 comprises:

[0086] A second driving member 81, the second driving member 81 is disposed on the outer rotating cover 5;

[0087] A knife seat 82, a limiting groove is provided on the outer rotating cover 5, the knife seat 82 is arranged in the limiting groove, and the second blade 7 is arranged on the knife seat 82;

[0088] The driving rod 83 is arranged in the limiting groove. The driving rod 83 is connected to the knife seat 82. When the second driving member 81 drives the driving rod 83 to rotate, it can drive the knife seat 82 to move in the limiting groove.

[0089] In this technical solution, the second driving member 81 is provided on the outer rotating cover 5 as the power source of the second driving part 8. The second driving member 81 is usually a high-precision, high-torque motor with good speed and torque control capabilities. Such a motor can accurately output power according to actual processing requirements to drive the movement of subsequent components.

[0090] The knife seat 82 is arranged in the limiting groove on the outer rotating cover 5, realizing the positioning and guiding functions of the knife seat 82. The shape and size of the limiting groove match the knife seat 82, which can not only ensure that the knife seat 82 moves smoothly therein, but also strictly limit its moving direction to prevent the knife seat 82 from deviating from the predetermined trajectory during the movement. The connection between the knife seat 82 and the second blade 7 is firm and reliable, ensuring that the second blade 7 will not loosen or shake during the trimming process, thereby ensuring the trimming quality.

[0091] The driving rod 83 is arranged in the limiting groove and connected to the knife seat 82. When the second driving member 81 drives the driving rod 83 to rotate, the driving rod 83 converts the rotational motion into the linear movement of the knife seat 82 in the limiting groove. In the actual punching and trimming operation, according to the size of the drug column and the trimming requirements, the second driving member 81 controls the rotation of the driving rod 83, and then drives the knife seat 82 to move in the limiting groove, so that the second blade 7 can accurately trim the edge of the coating layer on the end surface of the drug column. This precise control mechanism effectively avoids the problem of over-trimming or under-trimming in the trimming process, reduces the generation of flash, and improves the efficiency and quality of the entire processing process. At the same time, the limiting effect of the limiting groove on the knife seat 82, combined with the precise transmission of the driving rod 83, makes the second blade 7 more stable during the radial movement, further enhancing the reliability of the trimming operation.

[0092] Furthermore, an external thread is provided on the outer circumference of the driving rod 83 , and the knife seat 82 is threadedly connected to the driving rod 83 .

[0093] The second blade 7 is provided with a notch.

[0094] In this technical solution, when the second blade 7 moves in the limiting groove along with the blade holder 82 to trim the edge of the coating layer on the end of the medicine column, the incision can change the contact state between the blade and the coating layer. On the one hand, the incision enables the blade part of the second blade 7 to cut into the material in a more flexible posture at the moment of contacting the coating layer, effectively reducing the resistance during cutting. This helps to improve the fluency of the trimming operation, allowing the blade to move more smoothly along the edge of the coating layer, thereby completing the trimming task more accurately and reducing the uneven trimming caused by uneven resistance. At the same time, it can facilitate the second blade 7 to tilt for trimming operations, so that the bevel of the end face can be trimmed, effectively reducing the generation of flash on the coating layer on the end of the medicine column.

[0095] The first blades 4 are evenly distributed on the second end of the inner rotary cover 2 circumference.

[0096] In this technical solution, the circumferentially uniform arrangement of the first blades 4 ensures that the force acting on the coating layer on the end of the drug column can be evenly distributed during the punching process. When the inner rotary cap 2 contacts the coating layer on the end of the drug column under the coordinated action of the first drive unit 1 and the telescopic member 3 and starts the punching operation, each first blade 4 applies pressure to the coating layer at the same time. Since they are evenly distributed on the circumference, the punching impact force on the coating layer on the end of the drug column in all directions is relatively balanced, effectively avoiding problems such as deformation of the drug column and uneven damage to the coating layer due to excessive local force, thereby ensuring the consistency and stability of the punching quality.

[0097] Secondly, this uniform distribution method greatly improves the drilling efficiency. Compared with the non-uniform distribution or single-point drilling method, multiple first blades 4 perform drilling actions at the same time, which can complete the task of drilling a large area of ​​the end coating layer of the drug column in a short time. In the actual production process, this means that the drilling process of a batch of drug columns can be completed faster, significantly shortening the time required for the entire production process and improving production efficiency.

[0098] Furthermore, the first blades 4 evenly distributed around the circumference are also convenient for cooperating with the rotational movement of the inner rotary cover 2. When the inner rotary cover 2 is rotating and punching holes, each first blade 4 makes a circular motion around the center of the circle, and their motion trajectories can completely and evenly cover the circumferential area of ​​the coating layer on the end surface of the drug column. In this way, regardless of the size of the drug column, it can ensure a comprehensive and uniform punching effect within the entire circumference, and there will be no omission or uneven punching, which further improves the accuracy and integrity of the punching operation.

[0099] See attached Figure 8 As shown, the second aspect of the present application provides a punching and trimming device, comprising:

[0100] A workbench 9, on which a bracket is provided;

[0101] A fixture 10, wherein the fixture 10 is disposed on a workbench 9;

[0102] The punching and trimming structure of the first aspect embodiment is provided on the bracket.

[0103] The punching and trimming device provided in this embodiment, the workbench 9 as the supporting component of the whole device, is usually made of solid and flat materials, such as high-strength metal plates or thick engineering plastics, etc., to ensure that it can withstand various forces generated during the entire processing process, including the deadweight of the punching and trimming structure, the impact force generated during work, and the clamping force of the fixture 10 on the drug column. The bracket set on the workbench 9 provides a stable installation position for the punching and trimming structure, ensuring that the punching and trimming structure will not shake or move during work, thereby ensuring processing accuracy. The fixture 10 is set on the workbench 9, and its main function is to accurately clamp and position the drug column. The fixture 10 can firmly clamp the drug column to prevent the drug column from moving or rotating during the punching and trimming process. The punching and trimming operation can be performed at a stable and appropriate height and position. The punching and trimming structure is closely matched with the workbench 9 and the fixture 10. When the drug column is clamped and fixed on the workbench 9 by the fixture 10, the punching and trimming structure starts to work under power drive. Because it includes the perforated and trimmed structure of the first embodiment, it has all the beneficial effects of the perforated and trimmed structure.

[0104] The fixture 10 comprises:

[0105] A fixed plate, the fixed plate is arranged on the workbench 9, and clamping claws are symmetrically arranged on both sides;

[0106] The third driving member is arranged in the fixing plate and is used for driving the clamping jaws to move toward or in opposite directions.

[0107] In this technical solution, a fixed plate is arranged on the workbench 9, providing a stable platform for the installation and movement of the clamps. The clamps symmetrically arranged on both sides are the key part to realize the function of clamping the medicine column. The shape and size of the clamps are carefully designed according to the appearance characteristics of the medicine column, and the inner surface is usually specially treated, such as adding anti-slip texture or wrapping with soft materials, so as to provide greater friction when clamping the medicine column and prevent the medicine column from sliding or rotating during the punching and trimming process. The material of the clamps is also selected from metal materials with high strength and toughness to ensure that they will not deform or break when subjected to a large clamping force.

[0108] The third driving member is arranged in the fixed plate, and it plays a core driving role in the operation of the clamp 10. The third driving member can be in various forms such as an electric push rod, a hydraulic push rod or a pneumatic push rod, and is selected according to the actual application scenario and needs. When it is necessary to clamp the medicine column, the third driving member drives the jaws on both sides to move toward each other, and gradually applies the clamping force through the close contact between the jaws and the surface of the medicine column until the medicine column is firmly fixed in the middle of the clamp 10. In this process, the third driving member can accurately control the movement speed of the jaws and the size of the clamping force, ensuring that the clamping process can not only stably fix the medicine column, but also will not cause damage to the medicine column due to excessive clamping force.

[0109] When the processing is completed and the medicine column needs to be taken out, the third driving member drives the clamping jaws to move in the opposite direction, so that the clamping jaws release the clamping jaws on the medicine column, which facilitates the operator to smoothly take out the medicine column. This design that can realize the movement of the clamping jaws toward or in the opposite direction makes the clamp 10 highly flexible and operable, and can adapt to medicine columns of different sizes and shapes, thereby improving the versatility and practicality of the entire punching and trimming device.
