Description

Technical Field

[0001] This utility model relates to a pharmaceutical packaging equipment, and more particularly to a quantitative packaging machine for pharmaceutical granules. Background Technology

[0002] Granular medicines are generally packaged in bags for quantitative dispensing, which facilitates the preparation and administration of the medicine. Granular medicines need to be quantitatively filled into the packaging bag for quantitative administration. Currently, quantitative dispensing of medicine granules is mainly achieved by using a dispensing device to feed the medicine granules according to their volume, filling them into an open packaging bag, and then sealing the packaging bag with a sealing device to achieve quantitative packaging.

[0003] Traditional pharmaceutical granule quantitative packaging machines do not check the weight of each bag of medicine after packaging. Due to reasons such as the granular medicine sticking to the side wall of the feeding pipe during the quantitative dispensing process, the amount of granular medicine entering the packaging bag is difficult to guarantee. Therefore, the final packaged medicine bag cannot package the dosage stability, which is not conducive to the quantitative treatment of diseases.

[0004] Traditional quantitative packaging machines have a complex structure, are large in size, and generate significant noise during production. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a quantitative packaging machine for pharmaceutical granules. The quantitative packaging machine can ensure that the dosage of each bag of granular medicine is consistent, and the overall size of the packaging machine is compact, which can be effectively connected with subsequent cartoning equipment to realize intelligent pharmaceutical production and packaging.

[0024] Example: A quantitative packaging machine for pharmaceutical granules includes a frame 1, a storage tank 2, a quantitative drug feeding device 3, a first film tray 4, a second film tray 5, a side pressing drive roller 6, a side pressing pressure roller 7, a pressing drive device, a sealing pressing drive roller 8, a sealing pressing pressure roller 9, a sealing drive device, a cutting device 10, a drug package conveying device 11, a weighing device, a defective rejection device 12, a defective receiving box 16, and a controller. The first film tray 4 and the second film tray 5 are rotatably mounted on both sides of the frame 1. The side pressing drive roller 6, the side pressing pressure roller 7, the sealing pressing drive roller 8, and the sealing pressing pressure roller 9 are rotatably mounted on the frame 1 around a horizontal axis. The side pressing roller 7 and the side pressing roller 6 are arranged opposite each other. Both the side pressing roller 6 and the side pressing roller 7 are "I"-shaped rollers with outer diameters at both ends of the axial direction larger than the outer diameter at the middle. The outer circumferential surfaces of the two ends of the side pressing roller 7 and the outer circumferential surfaces of the two ends of the side pressing roller 6 can press the lateral edges of the two packaging films that are being conveyed forward from the first film tray 4 and the second film tray 5 to achieve lateral pressing and sealing of the packaging bag. The sealing pressing roller 8 and the sealing pressing roller 9 are arranged opposite each other. The sealing pressing roller 8 and the sealing pressing roller 9 form a material pulling convex ring 81 with an increased radial dimension at both ends of the axial direction. The sealing pressing roller 8 and the sealing pressing roller 9 are provided with at least one groove along the material pulling convex ring 81 at intervals in the middle. The sealing ribs 82 extending in the direction of the busbar, when the sealing pressing drive roller 8 and the sealing pressing pressure roller 9 rotate relative to each other, the material pulling rings 81 at both ends of the axial direction press the side of the packaging bag and pull the material forward, while the sealing ribs 82 on them perform fixed-length pressing and sealing of the forward conveyed packaging bag. The storage tank 2 is fixedly installed on the upper end of the frame 1, and the lower end of the storage tank 2 is provided with a discharge port. The quantitative drug delivery device 3 is installed on the frame 1 below the discharge tank. The discharge port of the storage tank 2 is connected to the inlet of the quantitative drug delivery device. The quantitative drug delivery device 3 can intermittently and quantitatively deliver the drug particles entering it to the upper opening and lower sealing end formed by the side pressing drive roller 6, the side pressing pressure roller 7, the sealing pressing drive roller 8 and the sealing pressing pressure roller 9. Inside the closed packaging bag, the cutting device 10 can cut the packaging bag, which has been sealed to a fixed length by the sealing pressing roller 8 and the sealing pressing pressure roller 9, into individual medicine packets. The medicine packet conveying device 11 can convey the individual medicine packets forward. A weighing device is installed on the medicine packet conveying device 11 to weigh the individual medicine packets. The weighing device communicates with the controller to provide feedback on the weight of each individual medicine packet. The controller determines whether the medicine packet is qualified based on the weight feedback from the weighing device. A defective rejection device 12 is installed on one side of the medicine packet conveying device 11, and a defective receiving box 16 is installed on the other side of the medicine packet conveying device 11. The controller can control the defective rejection device 12 to push the medicine packets that are determined to be unqualified into the defective receiving box 16.The control system controls the start and stop of the edge-pressing drive device, sealing drive device, cutting device 10, medicine bag conveying device 11, and defective rejection device 12.

[0025] When quantitatively packaging granular medicines, the granular medicines in the storage tank 2 enter the quantitative feeding device 3 under gravity. The quantitative feeding device 3 quantitatively conveys the granular medicines. At the same time, the first and second films led out from the first film tray 4 and the second film tray 5 are pulled into the space between the side pressing drive roller 6 and the side pressing pressure roller 7. The larger diameter parts at both ends of the side pressing drive roller 6 and the side pressing pressure roller 7 press the left and right side walls of the stacked first and second films together to make them bonded together. The films with their sides bonded together continue to be pulled downwards to the space between the sealing pressing drive roller 8 and the sealing pressing pressure roller 9. While the material pulling protrusions 81 at both ends of the sealing pressing drive roller 8 and the sealing pressing pressure roller 9 are pulling the material downwards along the bonded left and right sides of the first and second films, the sealing ribs 82 on the sealing pressing drive roller 8 and the sealing pressing pressure roller 9 intermittently press the first and second films laterally to form the top bag seal of the packaging. Simultaneously, the bottom of the upper packaging bag is sealed, and the quantitative feeding device 3 feeds the granular medicine quantitatively into the packaging bag with the bottom sealed and the top unsealed, thereby realizing the quantitative packaging of granular medicine. The packaged medicine bag continues to move downward, and the cutting device 10 cuts the sealing part of the adjacent medicine bag, so that the medicine bag is formed into a separate one. The separated individual medicine bags fall into the medicine bag conveying device 11 and are conveyed forward. At the same time, the weighing device weighs and detects each medicine bag. When the weight of the medicine bag exceeds the design range, the defective rejection device 12 rejects it into the defective receiving box 16. The qualified medicine bags continue to be conveyed forward and enter the cartoning station. The above packaging machine realizes the automatic compression and shaping of the packaging bag while quantitatively filling the packaging bag. The entire equipment has a simple structure, occupies little space, and each medicine bag is weighed and detected to avoid the situation of overfilling or underfilling of granular medicine in the medicine bag. Moreover, the equipment can be connected with the granular medicine production and cartoning line to form an intelligent production line.

[0026] Electric heating wires are respectively installed at both ends of the side pressing drive roller 6 and side pressing pressure roller 7. The electric heating wires can heat the axial ends of the side pressing drive roller 6 and side pressing pressure roller 7. Electric heating wires are also installed in the sealing ribs 82 of the sealing pressing drive roller 8 and sealing pressing pressure roller 9. The electric heating wires can heat the sealing ribs 82 of the sealing pressing drive roller 8 and sealing pressing pressure roller 9. By heating the pressing parts at both ends of the side pressing drive roller 6 and side pressing pressure roller 7, and by heating the sealing ribs 82 of the sealing pressing drive roller 8 and sealing pressing pressure roller 9, heat pressing is achieved, ensuring that the packaging bag is firmly pressed. Temperature sensors can also be installed on the side pressing drive roller 6, side pressing pressure roller 7, sealing pressing drive roller 8 and sealing pressing pressure roller 9 to detect the heat pressing temperature and prevent the film from being damaged by excessively high temperature or the pressing from being weak by excessively low temperature.

[0027] The outer circumferential surfaces of the side pressing active roller 6, side pressing pressure roller 7, sealing pressing active roller 8, and sealing pressing pressure roller 9 are also formed with concave and convex patterns 61, which can effectively improve the bonding strength of the first film and the second film.

[0028] The frame 1 is provided with a side pressing bracket and a sealing pressing bracket. The side pressing bracket is provided with a side pressing slider, and the sealing pressing bracket is provided with a sealing pressing slider. The side pressing roller 7 and the sealing pressing roller 9 are rotatably mounted on the side pressing slider and the sealing pressing slider, respectively. The side pressing slider and the sealing pressing slider are respectively able to slide linearly in the direction of the side pressing drive roller 6 and the sealing pressing drive roller 8. The side pressing bracket and the sealing pressing bracket are also provided with compression springs, which provide elastic force to the side pressing slider and the sealing pressing slider in the direction of the side pressing drive roller 6 and the sealing pressing drive roller 8, respectively.

[0029] The quantitative drug delivery device 3 includes a quantitative cylinder 31, a piston 32, a quantitative cylinder 33, a discharge pipe 34, and a baffle plate 35. An inlet is formed on the upper side of one end of the cylinder, which can communicate with the discharge port of the storage tank 2. An outlet is formed on the lower side of the other end of the cylinder, which communicates with the upper end of the discharge pipe 34. The lower end of the discharge pipe 34 is located between the side pressing drive roller 6 and the side pressing pressure roller 7. The piston 32 and the baffle plate 35 are fixedly connected and are arranged at intervals along the axial direction of the cylinder. A quantitative powder holding space 36 is formed between the piston 32 and the baffle plate 35. The piston rod 331 of the quantitative cylinder 33 is fixedly connected to the piston 32. The extension and retraction of the piston rod 331 of the cylinder can drive the quantitative holding space to communicate directly with the inlet or the discharge port. When granular medicine enters the powder-containing space of the metering cylinder 31 and fills the space, the metering cylinder 33 drives the piston 32 and the baffle plate 35 to move synchronously. At this time, the feed port of the metering cylinder 31 is closed, and the powder-containing space is connected to the discharge port of the metering cylinder 31. The granular medicine in the powder-containing space enters the discharge pipe 34 through the discharge port and enters the packaging bag through the lower end of the discharge pipe 34. The above structure can realize the fixed volume delivery of granular medicine. The structure is simple. When it is necessary to change the weight of each package of medicine, it is only necessary to adjust the distance between the piston 32 and the baffle plate 35 to change the volume of the powder-containing space.

[0030] The discharge port of the metering cylinder 31 is a funnel structure 37, and a vibrator is also installed on the outer wall of the funnel structure 37. The vibrator vibrates the side wall of the funnel structure 37 of the metering cylinder 31, causing the granular medicine adhering to the side wall of the funnel structure 37 to slide down, preventing it from sticking to the side wall of the funnel structure 37 and causing metering failure, thus improving the stability of metering.

[0031] The frame 1 is also equipped with several first guide rollers 13 and several second guide rollers 14, with one first guide roller 13 and one second guide roller 14 respectively located on both sides of the upper end of the discharge pipe 34. The first film drawn from the first film tray 4 is guided and turned by the several first guide rollers 13 into the space between the side pressing drive roller 6 and the side pressing pressure roller 7. The second film drawn from the second film tray 5 is guided and turned by the several second guide rollers 14 into the space between the side pressing drive roller 6 and the side pressing pressure roller 7. Ideally, the first film tray 4 and the second film tray 5 are equipped with damping devices to maintain a certain tension between the first film and the second film.

[0032] The cutting device 10 includes a cutter holder mounted on the frame 1, which can slide up and down a set distance. The cutter holder is located directly below the sealing and pressing drive roller 8 and the sealing and pressing pressure roller 9. The cutter holder has a cutter groove and a cutter that can slide horizontally into or out of the cutter groove. The cutter can cut off the sealing and pressing edge between two adjacent medicine packets. The cutter holder is also equipped with a cutter drive cylinder, which drives the cutter to reciprocate. The controller turns the cutter drive cylinder on and off. By adjusting the up and down position of the cutter holder, the cutter can cut off the sealing edge between adjacent medicine packets.

[0033] The medicine package conveying device 11 is a conveyor belt with several partitions spaced at intervals. Adjacent partitions form a package receiving trough capable of holding one medicine package at a time. The weighing device is a pressure sensor located on the bottom surface of each package receiving trough. The partitions divide the conveyor belt, ensuring each medicine package is placed in a separate trough to prevent it from falling out. Furthermore, a pressure sensor is installed in each trough to weigh the medicine package, ensuring accurate weighing data.

[0034] The frame 1 is also equipped with a bag guide slide 15. The upper end of the bag guide slide 15 is located directly below the cutting device 10, and the lower end of the bag guide slide 15 is directly opposite the starting end of the medicine bag conveying device 11. The bags cut by the cutting device 10 can slide forward in a straight line along the bag guide slide 15 one by one. The cut single bags slide down the guide slide to avoid multiple medicine bags from stacking and to ensure that each medicine bag enters a corresponding bag receiving slot on the conveyor belt.
