Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical production and packaging, and in particular to a drug bag cutting device for a drug packaging machine. Background Technology

[0002] Pharmaceutical packaging machines are key equipment for achieving precise pharmaceutical packaging and improving production efficiency. With the development of the medical industry, the requirements for the accuracy, efficiency, and quality of pharmaceutical packaging are becoming increasingly stringent.

[0003] Existing drug bag cutting devices often employ simple mechanical connections, lacking buffering and protection during the drug bag compression process. They are prone to breakage due to excessive pressure on drug bags of varying materials and thicknesses, exhibiting poor adaptability. Furthermore, the drug bag conveying and correction functions are flawed, with a single, inefficient, and unstable conveying method that fails to ensure uniform and continuous entry of the drug bag into the cutting area. In actual drug packaging operations, the drug bag position is easily misaligned, and existing patents generally lack effective real-time correction methods, severely impacting the accuracy and success rate of drug bag cutting. In addition, the cutting power and the coordination between the blade and the anvil are often suboptimal, frequently resulting in incomplete cutting and uneven cuts. This hinders subsequent packaging and sorting of the drug bags, and leads to disorganized bag collection, resulting in poor overall workflow continuity and efficiency. This restricts the efficiency and quality of drug packaging machines, increases costs for pharmaceutical manufacturers, and reduces production convenience and economic benefits. Therefore, those skilled in the art have provided a drug bag cutting device for drug packaging machines to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies. The proposed pharmaceutical preparation includes a base, with a mounting groove at the top center of the base. A plurality of conveying rollers arranged in an array are rotatably connected to the middle of the inner sidewall of the mounting groove. Limiting seats are installed on both sides of the mounting groove, near the front center of the top of the base. These limiting seats are mirror-image opposite each other. A first limiting groove is formed near one side of the middle of the inner sidewall of each limiting seat. A slider is slidably connected to the middle of the inner sidewall of each first limiting groove. Transmission grooves are formed between the first limiting grooves. The sliders are connected between... A transmission block is connected, and the transmission blocks are slidably connected to the inner sidewall of the corresponding transmission groove. An installation plate is installed at the top center of the limiting seat. A second cylinder is installed at the top center of the limiting plate. The output end of the second cylinder passes through the bottom center of the installation plate. Pressure plates are installed between the opposing sliders. A shearing blade is installed at the bottom of the front pressure plate. The input end of the front pressure plate is connected to the output end of the second cylinder. The height of the first limiting slide grooves opened on both sides of the shearing blade is higher than the two first limiting slide grooves on the rear side. A buffer spring is installed at the bottom center of the two first limiting slide grooves on the rear side.

[0005] Preferably, a limiting plate is installed on each of the two side walls of the slider, and the limiting plate is slidably connected to the middle position of the two side walls corresponding to the first limiting groove.

[0006] Preferably, a first cylinder is installed on both sides of the top center of the mounting groove, and a correction plate is installed on the output end of the first cylinder. The correction plate is movably connected above a plurality of conveying rollers.

[0007] Preferably, a support seat is installed on the top of the base and at the rear of the limiting seat. A limiting roller is rotatably connected to the upper end of the support seats. The input end of the limiting roller is connected to a first drive motor, which is installed on one side wall of any one of the support seats.

[0008] Preferably, the input end of the conveying roller is fitted with a transmission belt, and the input end of the rear conveying roller is connected to a second drive motor, which is installed on the upper rear side of one side wall of the base.

[0009] Preferably, a shearing plate is installed at the top center of the inner sidewall of the mounting groove near the front side, the shearing plate is located above the conveying roller, and the shearing plate matches the shearing blade.

[0010] Preferably, a collection box is installed at the middle position of the front side wall of the base.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, the limiting seat and the slider cooperate in a structure. The first limiting groove on the limiting seat and the limiting plates on both sides of the slider ensure the stability and accuracy of the pressure plate during movement. Compared with the simple mechanical connection method in some existing patents, this structure greatly reduces the shaking and deviation during device operation, and lowers the error rate of medicine bag cutting caused by inaccurate component displacement. At the same time, the buffer spring design at the bottom of the first limiting groove on the rear side is unique. Existing patents often neglect the buffer protection during the compression process of the medicine bag, while the buffer spring in this solution can automatically adjust the pressure according to the material and thickness of the medicine bag when the pressure plate is pressed down, preventing the medicine bag from being damaged due to excessive pressure. This structural optimization significantly improves the adaptability of the device to different types of medicine bags.

[0013] 2. This utility model integrates efficient medicine bag conveying and precise deviation correction functions. The conveying roller is driven by a second drive motor via a transmission belt. Compared with the single conveying method in some existing patents, the conveying efficiency is higher and the stability is stronger, ensuring that the medicine bag enters the cutting area at a uniform speed and continuously. Furthermore, the combination of the first cylinder on both sides of the top of the mounting groove and the deviation correction plate overcomes the shortcomings of existing patents. In the actual medicine packaging process, the position of the medicine bag is prone to deviation, and most existing patents lack effective real-time deviation correction methods. This solution can activate the first cylinder in real time according to the position of the medicine bag, pushing the deviation correction plate to adjust the position of the medicine bag, ensuring that the medicine bag is always in the optimal cutting position, greatly improving the accuracy and success rate of cutting.

[0014] 3. In this invention, the coordinated operation of the second cylinder, pressure plate, cutting blade, and cutting plate enables rapid and clean cutting of medicine bags. Compared to existing patents where insufficient power or poor blade-cutting mechanism leads to incomplete cutting and uneven cuts, this solution ensures a clean cut, facilitating subsequent packaging and organization. Furthermore, the collection box design at the front of the base facilitates medicine bag collection, eliminating the disorganized collection issues common in existing patents. This improves the overall workflow's continuity and efficiency, significantly enhancing the efficiency and quality of the drug packaging machine, and bringing greater economic benefits and production convenience to pharmaceutical manufacturers.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 — Figure 5 The medicine bag cutting device of the medicine repackaging machine includes a base 1, which has a reasonable structural design and can efficiently and stably complete the medicine bag cutting work.

[0023] Specifically, a mounting groove 7 is provided at the top center of the base 1. Several conveying rollers 15 arranged in an array are rotatably connected to the inner wall of the mounting groove 7. A transmission belt is fitted onto the input end of each conveying roller 15, and a second drive motor 14 is connected to the input end of the rear conveying roller 15. The second drive motor 14 is mounted on the upper rear side of one side wall of the base 1. Starting the second drive motor 14 drives the conveying rollers 15 to rotate via the transmission belt, thereby conveying the medicine bags within the mounting groove 7.

[0024] Specifically, a first cylinder 8 is installed on both sides of the top center of the mounting groove 7. A correction plate 9 is installed at the output end of each first cylinder 8, and the correction plate 9 is movably connected above several conveying rollers 15. During the transport of the medicine bag, the first cylinder 8 can be activated according to the actual position of the medicine bag. The first cylinder 8 pushes the correction plate 9 to correct the position of the medicine bag, ensuring that the medicine bag accurately reaches the subsequent cutting position.

[0025] Specifically, a support seat 2 is installed on the top of the base 1 and at the rear of the limiting seat 3. A limiting roller 12 is rotatably connected to the upper end of the support seats 2. The input end of the limiting roller 12 is connected to a first drive motor 13, which is installed on one side wall of any one of the support seats 2. When the medicine bag is conveyed between the limiting seats 3, the first drive motor 13 is started to drive the limiting roller 12 to rotate, which further limits and conveys the medicine bag, keeping the medicine bag in a stable conveying state.

[0026] Specifically, limit seats 3 are installed on both sides of the mounting groove 7 and at the top center of the base 1 near the front, with the limit seats 3 arranged in a mirror image. A first limiting groove 4 is formed on the inner wall of each limit seat 3 near one side. A slider 19 is slidably connected to the middle of the inner wall of each first limiting groove 4. Limiting plates 16 are installed on the two side walls of each slider 19, and the limiting plates 16 are slidably connected to the middle of the two side walls of the corresponding first limiting groove 4, limiting the slider 19 and ensuring its stability. Transmission grooves 5 are formed between the first limiting grooves 4, and transmission blocks are connected between the sliders 19, with the transmission blocks slidably connected to the inner wall of the corresponding transmission groove 5.

[0027] Specifically, a mounting plate 6 is installed at the top center of the limiting seat 3, and a second cylinder 10 is installed at the top center of the mounting plate 6. The output end of the second cylinder 10 passes through the bottom center of the mounting plate 6. Pressure plates 21 are installed between the opposing sliders 19. A cutting blade 11 is installed at the bottom of the front pressure plate 21, and the input end of the front pressure plate 21 is connected to the output end of the second cylinder 10. A cutting plate 17 is installed near the front center of the top center of the inner wall of the mounting groove 7. The cutting plate 17 is positioned above the conveying roller 15 and matches the cutting blade 11. When it is necessary to cut the medicine bag, the second cylinder 10 is activated, pushing the front pressure plate 21 downwards, causing the cutting blade 11 to engage with the cutting plate 17, thus cutting the medicine bag.

[0028] Specifically, the first limiting grooves 4 on both sides of the cutting blade 11 are higher than the two first limiting grooves 4 on the rear side, and buffer springs 20 are installed at the middle of the bottom of the two first limiting grooves 4 on the rear side. When the second cylinder 10 pushes the front pressure plate 21 downward, it drives the rear pressure plate 21 to move downward synchronously. The buffer springs 20 buffer the rear pressure plate 21, which can both ensure the compression effect on the medicine bag and prevent excessive pressure from damaging the medicine bag.

[0029] In addition, a collection box 18 is installed in the middle of the front side wall of the base 1 for collecting the cut medicine bags. In summary, the medicine bag cutting device of the medicine packaging machine of this utility model achieves stable conveying, accurate correction, efficient cutting and orderly collection of medicine bags through the coordinated work of various components. It has the advantages of reasonable structure, convenient operation and stable operation, and can effectively improve the working efficiency of the medicine packaging machine and the cutting quality of medicine bags.

[0030] Working principle: First, the medicine bag is placed on the conveyor roller 15 in the mounting groove 7 at the top of the base 1. The second drive motor 14 is started, and the second drive motor 14 drives several arrayed conveyor rollers 15 to rotate via a transmission belt, thereby realizing the conveying of the medicine bag. During the conveying process, according to the actual position of the medicine bag, the first cylinder 8 installed on both sides of the middle of the top of the mounting groove 7 can be activated. The output end of the first cylinder 8 pushes the correction plate 9 to correct the position of the medicine bag, ensuring that the medicine bag can accurately reach the cutting position.

[0031] When the medicine bag is conveyed to the limiting seat 3, the first drive motor 13 is started. The first drive motor 13 drives the limiting roller 12 to rotate. The limiting roller 12 plays a role in further limiting and conveying the medicine bag, so that the medicine bag maintains a stable conveying state. At this time, according to the need to cut the medicine bag, the second cylinder 10 is started. The output end of the second cylinder 10 pushes the front pressure plate 21 to move downward. Since the bottom of the front pressure plate 21 is equipped with a cutting blade 11, and the top middle of the inner wall of the mounting groove 7 is equipped with a cutting plate 17 that matches the cutting blade 11, the medicine bag can be cut when the cutting blade 11 moves downward and contacts the cutting plate 17.

[0032] As the second cylinder 10 pushes the front pressure plate 21 downward, the slider 19 connected to the front pressure plate 21 slides within the first limiting groove 4. Simultaneously, a transmission block connects the opposing sliders 19, sliding within the transmission groove 5, thereby driving the rear pressure plate 21 to move downward synchronously. Since buffer springs 20 are installed at the bottom center of both rear first limiting grooves 4, the rear pressure plate 21 is buffered by the buffer springs 20 as it moves downward, ensuring both the compression of the medicine bag and preventing excessive pressure from damaging it. Furthermore, limiting discs 16 are installed on both sides of the slider 19, sliding at the center of the two sides of the first limiting groove 4, limiting the slider 19 and ensuring its stability. Finally, the cut medicine bag falls into the collection box 18 installed at the center of the front side wall of the base 1, completing the cutting and collection of the medicine bag.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
