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, to ensure a complete, coated grain in the final product, the grain body is designed with a central hole. After the coating is applied to the end faces, the central hole in the coating needs to be punched out to align it perfectly with the central hole in the grain body. To achieve this, the coating must be trimmed and punched. This process involves precise shearing and punching techniques to ensure a perfect fit between the coating and the grain body. This ensures the overall structural stability of the grain while meeting design requirements, ultimately resulting in a structurally complete and fully functional coated grain.

[0003] Common grain punching and trimming machines currently on the market typically perform the punching and trimming processes separately. This behavior stems from the fact that existing machine designs simply combine the punching and trimming mechanisms without deeper integration. Consequently, this simple combination forces the machine to perform these two operations separately. This not only increases processing time but also reduces overall production efficiency.

[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 provided 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 provided on a second end of the inner rotary cover 2;

[0058] The outer cover 5 is concentrically arranged on the outside of 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] The second driving part 8 is provided 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 drive unit 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 set between the output end of the first drive unit 1 and the first end of the inner rotating cap 2. The telescopic member 3 can not only transmit the power of the first drive unit 1 in the axial direction to cause the inner rotating cap 2 to move axially, but also can 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] A first blade 4, mounted on the second end of the inner cap 2, is used for drilling holes. The shape, material, and cutting edge design of the first blade 4 have been carefully optimized to meet the requirements of drilling holes in the grain end coating. It is typically made of a high-strength, high-hardness alloy that maintains its sharpness during high-speed rotation and downward pressure, effectively penetrating the grain coating.

[0063] The outer cap 5 is concentrically positioned outside the inner cap 2, and the two are connected by multiple transmission members 6. The transmission members 6 transmit the rotational motion of the inner cap 2 to the outer cap 5, providing the basis for trimming and punching operations. A second blade 7, mounted on the outer cap 5, is used for trimming operations, accurately trimming the edge of the coating on the end surface of the grain. A second drive unit 8, mounted on the outer cap 5, powers the radial movement of the second blade 7, enabling it to trim the material at different radial positions, meeting the processing requirements of grains of varying sizes.

[0064] During actual operation, after the equipment is started, 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 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 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 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 reducing processing time, improving the efficiency of the entire production process, and avoiding the problems caused by the existing machines operating the two processes separately.

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

[0066] The telescopic member 3 comprises:

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

[0068] A second telescopic rod 32, wherein a mounting groove is formed at a first end of the second telescopic rod 32, and a second end of the first telescopic rod 31 is slidably disposed in the mounting groove, and the second end of the second telescopic rod 32 is connected to the 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 the 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 drive unit 1. It is typically made of a high-strength metal material, possessing excellent rigidity and strength to withstand the forces and torques transmitted during operation. The mounting groove defined at the first end of the second telescopic rod 32 slides with the second end of the first telescopic rod 31 to achieve flexible telescopic movement. This sliding arrangement allows the first telescopic rod 31 to move smoothly within the mounting groove, thereby adjusting 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 enabling axial position adjustment of the inner rotating cover 2.

[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 conjunction 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 pull 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 medicine 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 end surface of the medicine column, while ensuring the stability and accuracy of the entire punching and shearing process.

[0072] The transmission member 6 includes:

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

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

[0075] The protrusion 63 is provided with a sliding 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 sliding groove.

[0076] In this technical solution, the first elastic member 61 and the movable plate 62 are located within a groove on the inner circumference of the outer cover 5. When subjected to external forces, the first elastic member 61 can undergo elastic deformation within a certain range, storing and releasing energy during the deformation process. This ensures a stable connection between the outer cover 5 and the inner cover 2 throughout the entire operation process. The protrusion 63 is located within a chute on the outer circumference of the inner cover 2. The protrusion 63 is connected to the end of the movable plate 62 away from the first elastic member 61. This connection ensures that the movement of the inner cover 2 can be transmitted to the inner cover 2 via the protrusion 63 and the movable plate 62. This transmission method not only ensures the synchronous rotation between the outer cover 5 and the inner cover 2, but also can, to a certain extent, accommodate minor displacements and deformations that may occur during the processing process, 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 act as a buffer during movement, reducing damage to the inner cover 2 and the outer cover 5 caused by impact or vibration, thereby extending the service life of the entire punching and trimming structure.

[0077] The transmission member 6 further includes a connecting member 64, which 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 provided 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 provided 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 solution, when the outer cover 5 begins to rotate and move, the first elastic member 61 responds to the shape of the groove. At the straight end, the first elastic member 61 remains relatively stable, and the movable plate 62 and its connected first baffle 641 are also in a stable position, preventing malfunctions caused by slight disturbances.

[0083] However, when the motion is transmitted to the inclined section of the groove, the situation changes. The presence of the inclined section changes the direction of force applied to 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 movement of the first baffle 641. Because 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 within the arc-shaped groove. This relative sliding, under the action of the torsion spring 645, generates a restoring force related to the direction of motion. This restoring force, combined with the elastic force of the first elastic member 61, precisely controls the movement of the protrusion 63 within the groove.

[0084] During the punching operation, as the outer cap 5 rotates and the inclined section of the groove guides the transmission, the inner cap 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 of the end surface of the drug column at the optimal angle and force, reducing errors in the punching process and unnecessary damage to the drug column. During the trimming operation, the same principle enables the relative position between the outer cap 5 and the inner cap 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 of the end surface of the drug column, effectively controlling the accuracy and quality of the trimming, and reducing the flash phenomenon, thereby making the entire punching and trimming process more efficient and accurate.

[0085] The second driving unit 8 includes:

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

[0087] The knife seat 82 is provided with a limiting groove 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 drive element 81, serving as the power source for the second drive unit 8, is located on the outer rotating cover 5. This second drive element 81 is typically a high-precision, high-torque motor with excellent speed and torque control capabilities. This motor can accurately output power according to actual processing requirements to drive the movement of subsequent components.

[0090] The blade holder 82 is positioned within the retaining groove on the outer cover 5, providing both positioning and guidance for the blade holder 82. The shape and size of the retaining groove match the blade holder 82, ensuring smooth movement within the groove while also strictly limiting its direction of movement, preventing it from deviating from its intended trajectory. The secure connection between the blade holder 82 and the second blade 7 ensures that the blade 7 does not loosen or wobble during trimming, thereby ensuring high-quality trimming.

[0091] The drive rod 83 is arranged in the limiting groove and is connected to the knife holder 82. When the second drive member 81 drives the drive rod 83 to rotate, the drive rod 83 converts the rotational motion into a linear movement of the knife holder 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 drive member 81 controls the rotation of the drive rod 83, thereby driving the knife holder 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 burrs, 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 holder 82, combined with the precise transmission of the drive rod 83, makes the second blade 7 more stable during 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 with the blade holder 82 in the limiting groove to trim the edge of the coating layer on the end of the drug column, the incision can change the contact state between the blade and the coating layer. On the one hand, the incision enables the blade portion of the second blade 7 to cut into the material in a more flexible posture at the moment of contact with the coating layer, effectively reducing the resistance during cutting. This helps to improve the smoothness 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 drug 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 uniform distribution of the first blades 4 around the circumference ensures that the force acting on the coating layer on the end of the charge is evenly distributed during the drilling process. When the inner rotary cap 2 contacts the coating layer on the end of the charge under the coordinated action of the first drive unit 1 and the telescopic member 3 and begins the drilling operation, each first blade 4 simultaneously applies pressure to the coating layer. Because they are evenly distributed around the circumference, the drilling impact force on the coating layer on the end of the charge is relatively balanced in all directions, effectively avoiding problems such as deformation of the charge and uneven damage to the coating layer due to excessive local force, thereby ensuring the consistency and stability of the drilling quality.

[0097] Secondly, this uniform distribution greatly improves drilling efficiency. Compared to non-uniform distribution or single-point drilling, multiple first blades 4 perform the drilling action simultaneously, enabling the completion of a large area of ​​the grain end coating in a shorter time. In actual production, this means that the drilling process for a batch of grains can be completed more quickly, significantly shortening the entire production process and improving production efficiency.

[0098] Furthermore, the uniform distribution of first blades 4 around the circumference facilitates coordination with the rotational motion of the inner rotary cap 2. As the inner rotary cap 2 rotates and punches holes, each first blade 4 performs a circular motion around the center of the circle, their motion paths ensuring complete and uniform coverage of the circumference of the grain end coating. This ensures comprehensive and uniform punching across the entire circumference, regardless of the size of the grain, preventing missed or uneven punching. This further enhances the precision and integrity of the punching operation.

[0099] Refer to the 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 is provided on the workbench 9;

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

[0103] In the punching and trimming device provided in this embodiment, the workbench 9 serves as the supporting component of the entire device. It is typically constructed of a sturdy and flat material, such as high-strength sheet metal or thick engineering plastic, to ensure it can withstand the various forces generated throughout the entire machining process, including the weight of the punching and trimming structure, the impact forces generated during operation, and the clamping force of the clamp 10 on the grain. A bracket mounted on the workbench 9 provides a stable mounting position for the punching and trimming structure, ensuring that it does not wobble or shift during operation, thereby ensuring machining accuracy. The clamp 10, mounted on the workbench 9, primarily functions to precisely clamp and position the grain. The clamp 10 securely holds the grain, preventing it from moving or rotating during the punching and trimming process. This allows the punching and trimming operations to be performed at a stable and appropriate height and position. The punching and trimming structure works closely with the workbench 9 and clamp 10. Once the grain is clamped and secured to the workbench 9 by the clamp 10, the punching and trimming structure begins operation under power. 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] The fixed plate is arranged on the workbench 9, and has clamping claws symmetrically arranged on both sides;

[0106] The third driving member is arranged in the fixed plate and is used to drive 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 achieve the function of clamping the drug column. The shape and size of the clamps are carefully designed according to the external characteristics of the drug column. The inner surface is usually specially treated, such as adding anti-slip grooves or wrapping with soft materials, so as to provide greater friction when clamping the drug column and prevent the drug column from sliding or rotating during the punching and shearing 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 large clamping forces.

[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 charge is removed after processing is complete, the third drive member drives the jaws in the opposite direction, releasing their grip on the charge and allowing the operator to remove it smoothly. This design, which enables the jaws to move toward or away from each other, makes the clamp 10 highly flexible and easy to use, adapting to charges of various sizes and shapes, thereby improving the versatility and practicality of the entire punching and trimming device.

[0110] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application. The above are merely preferred embodiments of the present application. It should be noted that those skilled in the art may make various improvements and variations without departing from the technical principles of the present application, and such improvements and variations shall also be considered within the scope of protection of the present application.
