Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an adjustable-spacing slitting mechanism suitable for tablets of different diameters. Background Technology

[0002] In solid dosage form production lines in the pharmaceutical, food, and chemical industries, small granular dosage forms such as tablets and pills typically need to be counted and dispensed before packaging. Therefore, the tablet-splitting mechanism is an indispensable key structure in related automated equipment. Existing tablet-splitting mechanisms mostly employ a dual-cylinder structure, using two cylinders to reciprocate and drive corresponding baffles to intercept and release tablets one by one, thus forming a stable tablet-splitting rhythm. However, the cylinder positions in most traditional dual-cylinder tablet-splitting mechanisms are fixed, and their center distance cannot be adjusted, resulting in the minimum distance between the two baffles being limited by the structural dimensions of the cylinders.

[0003] Because the cylinder mounting position is fixed, when the tablet diameter is smaller than the cylinder center distance, even if the piston rod is fully retracted, a narrow gap suitable for small-sized tablets to pass through cannot be formed, preventing the equipment from effectively slicing small-diameter tablets. For example, when the cylinder center distance is 10mm, it is impossible to stably intercept tablets with a diameter of approximately 8mm or smaller. To accommodate different tablet sizes, existing equipment often requires replacing the tablet baffle assembly with a different size or modifying the entire slicing mechanism, which not only increases structural complexity but also raises equipment maintenance and operating costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-spacing slitting mechanism suitable for tablets of different diameters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-spacing tablet-splitting mechanism suitable for tablets of different diameters includes a fixed seat mounted on a conveying mechanism. The conveying mechanism has a groove. A telescopic cylinder 1 and a telescopic cylinder 2 are mounted on the top of the fixed seat. A piston rod 1 and a piston rod 2 are respectively provided at one end of the telescopic cylinder 1 and the telescopic cylinder 2. A through hole is opened on the top of the fixed seat, and the piston rod 1 and the piston rod 2 are disposed through the through hole. A connecting block is installed at one end of the piston rod 2 by a fastening bolt 1. A vertically arranged movable rod is installed on the side of the connecting block near the piston rod 1 by a fastening bolt 1.

[0007] Preferably, the connecting block has two placement holes, and one end of the piston rod and the movable rod are both disposed through the two placement holes.

[0008] Preferably, threaded holes are provided on one side wall of both placement holes, and fastening bolts are installed through the threaded holes.

[0009] Preferably, the ends of the movable rod and the piston rod near the conveying mechanism are each provided with protective sleeves, and the positions of the movable rod and the piston rod correspond to the positions of the grooves.

[0010] Preferably, both the telescopic cylinder one and the telescopic cylinder two are provided with mounting wings on their sides, and the mounting wings are mounted on the top of the fixed base by fastening bolts two.

[0011] Preferably, the top of the fixing seat is provided with a positioning groove, and one end of the fastening bolt is located in the positioning groove.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention overcomes the limitation of traditional dual-cylinder tablet-splitting mechanisms by incorporating two movable telescopic cylinders mounted on a fixed base. These cylinders, a linkage between a connecting block and a movable rod, allow for continuous adjustment of the distance between the movable rod and piston rod 1 according to the tablet diameter. This structure enables full-size adaptation from large-diameter tablets to micro-tablets as small as 2-3 mm, facilitating rapid switching without the need for parts replacement and significantly improving the equipment's versatility.

[0014] During operation, two sets of piston rods alternately intercept and release the tablets, achieving a stable and reliable tablet-by-tablet separation action. The separation rhythm is clear and the positioning is accurate, effectively avoiding double tablets, missing tablets, and other issues, thus improving counting and packaging accuracy. At the same time, the entire mechanism has a compact structure, few parts, and is easy to maintain, making it suitable for large-scale continuous operation.

[0015] This invention has broad application prospects and can be widely used in the slicing, counting and packaging equipment for solid dosage forms such as tablets and pills in the pharmaceutical, food and chemical industries, which will help promote the upgrading of related automated production lines.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1 to 5 An adjustable-spacing tablet-splitting mechanism suitable for tablets of different diameters includes a fixed seat 3 mounted on a conveying mechanism 1. The conveying mechanism 1 has a groove 2. A telescopic cylinder 5 and a telescopic cylinder 6 are mounted on the top of the fixed seat 3. A piston rod 9 and a piston rod 13 are respectively provided at one end of the telescopic cylinder 5 and the telescopic cylinder 6. A through hole 7 is opened on the top of the fixed seat 3. The piston rod 9 and the piston rod 13 are disposed through the through hole 7. A connecting block 10 is installed at one end of the piston rod 13 by a fastening bolt 14. A vertically arranged movable rod 11 is installed on the side of the connecting block 10 near the piston rod 9 by a fastening bolt 14.

[0024] In a preferred embodiment of this utility model, the connecting block 10 is preferably integrally formed from materials such as aluminum alloy, carbon steel, or high-strength engineering plastics, possessing good rigidity and wear resistance, and maintaining stable structural performance during long-term reciprocating motion. The overall structure of the connecting block 10 is square column-shaped or elongated, with two vertically penetrating placement holes 15 inside, respectively used to accommodate the end of the piston rod 13 and the upper end of the movable rod 11, enabling reliable connection and synchronous transmission between the two through the same structure.

[0025] The connecting block 10 has threaded holes on its sidewalls, through which fastening bolts 14 are inserted to apply locking force to the piston rod 13 and the movable rod 11. By tightening the fastening bolts 14, the two rods are positioned and fixed within the placement hole 15, thus ensuring that the movable rod 11 achieves stable and wobbly linear movement under the drive of the telescopic cylinder 6. This structure is not only easy to assemble, but also easy to disassemble and maintain.

[0026] During operation, the connecting block 10 plays a crucial role in connecting and transmitting motion. When the telescopic cylinder 26 drives the piston rod 23 to reciprocate, the connecting block 10 moves synchronously, causing the movable rod 11, which is fixedly connected to it, to extend and retract linearly, enabling the movable rod to accurately perform the interception or release action on the tablet. Because the connecting block 10 is located close to the middle between the two piston rods, its compact structure effectively reduces the installation distance between the two rods, allowing for a smaller minimum clearance between the movable rod 11 and the piston rod 9. This is of decisive significance for adapting to small-diameter tablets.

[0027] Furthermore, the double-hole structure of the connecting block 10 allows for quick replacement and displacement adjustment of the movable rod 11, facilitating the adaptation and conversion of tablets of different specifications. The design of the connecting block 10 significantly improves the compactness, transmission stability, and adaptability of the slicing mechanism of this invention, further enhancing the versatility and slicing accuracy of the equipment.

[0028] In a preferred embodiment of this utility model, threaded holes are provided on one side wall of both placement holes 15, and fastening bolt 14 is inserted through the threaded holes.

[0029] In a preferred embodiment of the present invention, protective sleeves 12 are provided at the ends of the movable rod 11 and the piston rod 9 near the conveying mechanism 1, and the positions of the movable rod 11 and the piston rod 9 correspond to the positions of the groove 2.

[0030] In this embodiment, the protective sleeve 12 is preferably made of polytetrafluoroethylene, polyoxymethylene (POM), nylon (PA) or abrasion-resistant polymer engineering plastic material, which has good abrasion resistance, low coefficient of friction and certain elasticity, and is suitable for hygiene requirements where it comes into direct contact with pharmaceutical tablets.

[0031] The protective sleeve 12 is fitted onto the ends of the movable rod 11 and the piston rod 9. Its outer surface is smooth and rounded. When the piston rod is inserted into the groove 2 or comes into contact with the tablet, it can effectively prevent direct friction between the metal rod and the inner wall of the conveying groove, reducing wear and metal scratches. At the same time, the material of the protective sleeve 12 has a certain cushioning performance, which can significantly reduce the pressure acting on the tablet surface when intercepting the tablet, avoiding tablet breakage, flattening, or corner defects caused by the rigid compression of the piston rod, thereby ensuring the smoothness and reliability of the tablet splitting action.

[0032] Furthermore, the protective sleeve 12 is easy to disassemble and replace. After long-term operation, it can be replaced individually without replacing the entire piston rod assembly, which is beneficial for equipment maintenance and hygiene management. By setting up the protective sleeve, this utility model not only improves the stability of tablet splitting but also further reduces frictional resistance, extends the service life of the mechanism, and effectively ensures the integrity of the tablet splitting process.

[0033] As a preferred embodiment of the present invention, both telescopic cylinder 5 and telescopic cylinder 6 are provided with mounting wings 4 on their sides. The mounting wings 4 are mounted on the top of the fixed base 3 by fastening bolt 2 16. The top of the fixed base 3 is provided with a positioning groove 8, and one end of the fastening bolt 2 16 is located in the positioning groove 8.

[0034] In this embodiment, the mounting wing 4 is preferably made of a single piece of metal sheet, and has through holes for mounting the second fastening bolt 16. Through the mounting wing 4, the telescopic cylinder 5 and the second telescopic cylinder 6 can be reliably connected to the fixed base 3, making the overall mounting structure of the telescopic cylinders more stable and less prone to displacement due to long-term reciprocating motion.

[0035] The positioning groove 8 serves a dual purpose of guiding and limiting. On the one hand, it allows the telescopic cylinder 5 and the telescopic cylinder 6 to be positioned on the fixed base 3 along the length of the positioning groove. On the other hand, it restricts the lateral movement of the cylinders perpendicular to the length of the groove, thereby maintaining a stable and reliable installation position after adjustment.

[0036] In practical use, the operator can loosen the second bolt 16 appropriately, allowing the telescopic cylinders 5 and 6 to slide along the length of the positioning groove 8, thereby changing the relative distance between the two cylinders and adjusting the actual segmentation distance between the movable rod 11 and the piston rod 9 to accommodate tablets of different diameters. After adjusting to the target position, tightening the second bolt 16 again will securely lock the two telescopic cylinders onto the fixed base 3, ensuring that no positional shift occurs during the segmentation process.

[0037] By installing the side wing 4, fastening bolt 2 16 and positioning groove 8, the installation of the telescopic cylinder has good adjustability and stability, realizing a comprehensive improvement in adaptability, assembly and maintenance and structural strength of the segmented mechanism of this utility model.

[0038] In the use of this utility model, telescopic cylinder 5 and telescopic cylinder 6 are both installed on the top of the fixed base 3 and can be adjusted in position along the positioning groove 8 provided on the fixed base 3. By adjusting the installation position of the two telescopic cylinders on the fixed base, the distance between the movable rod 11 and the piston rod 9 can be changed according to the size of the tablet diameter, so that the tablet-splitting mechanism can adapt to tablets of different sizes.

[0039] The conveying mechanism 1 is used to carry and transport tablets, which slide forward along the groove 2 of the conveying mechanism. When a tablet enters the tablet-splitting area, telescopic cylinder 5 and telescopic cylinder 6 drive their corresponding piston rods 9 and 13 to reciprocate and extend, respectively, to intercept and release the tablets one by one.

[0040] During operation, the telescopic cylinder 5 first drives the piston rod 9 downward until the bottom end of the piston rod 9 abuts against the bottom inner wall of the groove 2. At this time, the piston rod 9 is in the tablet's travel path, intercepting the first target tablet. At the same time, since the movable rod 11 is connected to the piston rod 13 through the connecting block 10, the movable rod 11 is now in a position above the conveying mechanism 1, which does not affect the interception of the first target tablet.

[0041] When telescopic cylinder 5 drives piston rod 9 upward and gradually moves away from the groove 2 area, telescopic cylinder 6 drives piston rod 13 downward, causing movable rod 11 to descend until the bottom end of movable rod 11 abuts against the top of the second target tablet. At this time, the first target tablet, which was originally blocked by piston rod 9, moves under the push of the conveying mechanism to below piston rod 9, thus successfully falling into the material or entering the next process.

[0042] After the first target tablet is fed, the telescopic cylinder 5 pushes the piston rod 9 downward again, causing its bottom end to press against the bottom inner wall of the groove 2, thus creating a new interception for subsequent tablets. At the same time, the telescopic cylinder 6 drives the movable rod 11 upward away from the tablet, allowing the second target tablet to continue moving forward and be intercepted by the piston rod 9.

[0043] The above actions are repeated continuously to achieve the function of tablet-by-tablet separation and conveying. Through the linkage structure between the connecting block 10 and the movable rod 11, the distance between the movable rod 11 and the piston rod 9 can be significantly reduced, thereby ensuring that this tablet-separating mechanism can adapt to tablets of different diameters, including stable separation of small-diameter tablets. The structural design of this utility model significantly improves its adaptability, separation accuracy, and versatility.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
