Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine granule packaging equipment, and in particular to a Chinese medicine granule quantitative preparation equipment. Background Art

[0002] my country's traditional Chinese medicine culture has a long history and rich resources, but currently China only accounts for a small part of the world's traditional Chinese medicine exports. The main reason is that my country still uses primitive methods of dispensing raw herbs, hand-grabbing and weighing. In the process of dispensing traditional Chinese medicine, the speed is slow, the measurement error is large, and it is difficult to keep pace with the international market where medicine dispensing is standardized, standardized and scientific.

[0003] With the development of science and technology, some hospitals have begun to use mechanical automatic medicine dispensing. In order to meet the needs of mechanized medicine dispensing, the existing medicine dispensing machines use medicine boxes with fixed shapes. After the Chinese medicine is put into the medicine box, the surface of the medicine box is sealed with a plastic film. However, the medicine box takes up a lot of space, is expensive, and is inconvenient to carry. If the bag packaging method can be used, it can save costs and be easy to carry.

[0004] There are two main existing bag packaging methods. One is to use packaging bags made in batches and open them by means of vacuum suction cups before dispensing. However, the mechanical structure involved in this method is complex, and the opening effect is uncontrollable, which can easily lead to leakage of medicine due to incomplete opening. The vacuum suction cup is noisy, which affects the work of doctors and does not meet the use requirements of hospital pharmacies. Another opening method is to use a funnel-like structure to open the bag mouth, but the mechanism used to open the bag mouth will cause pollution to the medicine bag, which is not suitable for the field of pharmacy dispensing where the formula is constantly changing. The second is to use packaging film to directly wrap the surface of the product and then seal it into a bag. This method is only used for packaging scenarios where the shape and size of the product to be packaged are relatively fixed. However, the dispensing packaging of Chinese medicine granules is affected by the doctor's advice, and the situations of different people vary greatly, so this packaging method is not suitable for use.

[0005] A continuous metering feeding device for Chinese medicine granules with publication number CN205045020 discloses a medicine bottle and a feeding port structure. The medicine bottle is driven by the feeding port to make the Chinese medicine granules in the medicine bottle quantitatively fall into the medicine box below it. The feeding port and medicine bottle of the above structure can realize the quantitative feeding function of the medicine box. However, if the medicine box is replaced with a medicine bag, since the opening area of ​​the medicine bag is small and the opening shape is difficult to control, the medicine bag control mechanism must be redesigned to cooperate with the above feeding device, keep the opening during the feeding process, and complete automatic feeding.

[0006] In addition, since the packaging bags are easily deformed and their shapes are difficult to control, the dosage of medicines in different prescriptions fluctuates greatly. After the Chinese medicine granules are loaded into the medicine bags, the opening shape of the medicine bags and the proportion of the Chinese medicine granules in the volume of the packaging bags will have a significant impact on the sealing quality of the medicine bags. Currently, ordinary sealing equipment cannot meet the above requirements. Summary of the invention

[0081] The medicine bag sealing mechanism 300 includes a sealing component 3 for sealing the bagged Chinese medicine, a displacement component 4 for driving the sealing component 3 to translate, and a lifting component 5 for driving the bagged Chinese medicine to lift.

[0082] The quantitative preparation device of Chinese medicine granules of the present invention integrates a bag making mechanism 400, a feeding mechanism 100, a medicine bag manipulation mechanism 200 and a medicine bag sealing mechanism 300, and has a simple structure and a small size. Through the cooperation of the bag making mechanism 400, the feeding mechanism 100, the medicine bag manipulation mechanism 200 and the medicine bag sealing mechanism 300, the bags are made on site in real time.

[0083] like Figure 4 As shown, the bag-making mechanism also includes a film storage mechanism 61 for storing bag-making film; the film storage mechanism 61 is arranged inside the machine. The plastic film parts include a first plastic film part 62 and a second plastic film part 64; the first plastic film part 62 is connected to a plastic film core 63 at its end, and is used to gradually bend the bag-making film from both sides and cover the plastic film core 63; the second plastic film part 64 is located below the first plastic film part 62 and is sleeved on the outer periphery of the plastic film core 63, and is used to perform secondary shaping on the bag-making film; the side sealing mechanism 65 is arranged below the second plastic film part 64, and is used to seal the side of the bag-making film; the bottom sealing mechanism 7 is arranged below the plastic film core 63; the breaking mechanism 8 is arranged below the bottom sealing mechanism 7.

After the medicine bag is placed in the fixing frame 23, it can be transferred to the unloading station for unloading without the need for an additional opening step, thus simplifying the structure of the unloading mechanism 100 and avoiding the possible contamination of the medicine bag by opening the bag opening with tools. The above structure can realize the multi-station automatic unloading and sealing function of the medicine, meeting the needs of automatic dispensing in pharmacies.

[0087] The device is divided into three major components and its structure and principle are explained in detail below.

[0088] 1. Bag making mechanism.

[0089] The bag making mechanism comprises a film storage mechanism 61, a first plastic film component 62, a plastic film core 63, a second plastic film component 64, a side sealing mechanism 65, a film driving mechanism 66, a bottom sealing mechanism 7 and a breaking mechanism 8; the film storage mechanism 61 is used to store the bag making film 10;

[0090] Combination Figure 5 and Figure 6The first plastic film part 62 includes a guide surface 621, an edge guide groove 622 and a limit strip 623, wherein the edge guide groove 622 is provided at both side edges of the guide surface 621, the limit strip 623 is provided above the guide surface 621, and the lower end of the guide surface 621 is connected to the plastic film core 63;

[0091] Combination Figure 7 The second plastic film member 64 is located below the first plastic film member 62 and is sleeved on the periphery of the plastic film core 63, and includes an annular guide member 641;

[0092] The side sealing mechanism 65 is disposed below the second plastic film member 64 and faces the side edge of the bag-making film 10 to be sealed, and is used to seal the side edge of the bag-making film 10;

[0093] The bottom sealing mechanism 7 is disposed below the side sealing mechanism 65 and is used to seal the bottom edge of the bag-making film 10;

[0094] The separating mechanism 8 is arranged below the bottom sealing mechanism 7 and is used to separate medicine bags of a predetermined length;

[0095] Combination Figure 8 The film driving mechanism 66 includes driving wheels 661 symmetrically arranged on both sides of the plastic film core 63, a synchronous gear 662 connected to the driving wheel 661 and a second motor 663 for driving the synchronous gear 662, which is used to drive the bag-making film 10 to pass through the first plastic film part 62, the second plastic film part 64, the side sealing mechanism 65, the bottom sealing mechanism 7 and the breaking mechanism 8 in sequence.

[0096] The present invention shapes the bag-making film 10 through the plastic film core 63, the first plastic film part 62 and the second plastic film part 64, seals the side and bottom edges of the medicine bag through the side sealing mechanism 65 and the bottom sealing mechanism 7, and finally cuts off the upper part of the medicine bag with side and bottom sealing through the cutting mechanism 8, so as to carry out the subsequent dispensing work. Preferably, the horizontal cross-section of the plastic film core 63 is polygonal, so that the bag-making film forms a certain number of edges. More preferably, the horizontal cross-section of the plastic film core 63 is rectangular or trapezoidal. After the bag-making film 10 passes through the plastic film core 63 with a rectangular or trapezoidal horizontal cross-section, four edges with a certain curvature will be formed, so as to ensure that the upper opening of the manufactured medicine bag remains open after being separated from the bag-making film 10, and a cavity is formed inside, and the duration of the opening is longer, it is not easy to deform, and it is more conducive to material unloading. In the subsequent dispensing work, the Chinese medicine particles can fall directly from the medicine bottle into the open medicine bag without the need for additional guides, thus avoiding drug contamination caused by contact between different types of Chinese medicine particles and the guides during the dispensing process.

[0097] like Figure 7As shown, in order to guide the bag-making film 10 to smoothly wrap the plastic film core 63 from the initial plane shape and overlap the edges on both sides to form a side-sealed part, the upper end of the annular guide member 641 is provided with an outer guide slope 647, and a side-sealing guide slope 648 is provided at the position corresponding to the side seal of the medicine bag, and a side-sealing opening 642 is provided below the side-sealing guide slope 648. The outer guide slope 647 can gather the bag-making film 10 and wrap it around the periphery of the plastic film core 63, and the side-sealing guide slope 648 gradually gathers the side-sealed part of the bag-making film 10 so that the overlapping part enters the side-sealing opening 642 to form a part to be side-sealed.

[0098] Preferably, the second plastic film member 64 further comprises a second plastic film base 643 provided with the side seal opening 642, an opening fixing block 644 is provided on the second plastic film base 643, a fixing pin 645 is provided on the second plastic film base 643, and a positioning hole 646 is provided on the opening fixing block 644. The opening fixing block 644 fixes the fixing pins 645 located on both sides of the side seal opening 642 through its positioning hole 646, thereby ensuring that the side seal opening 642 has a predetermined gap. When the opening fixing block 644 is separated from the fixing pin 645, the annular guide member 641 of the second plastic film member 64 will open outwards, increasing the gap between the annular guide member 641 and the plastic film core 63, so as to facilitate the bag-making film 10 to pass through the gap between the second plastic film member 64 and the plastic film core 63 again when replacing or maintaining. The opening fixing block 644 is directly fixed through the fixing pin 645 through the positioning hole 646. When disassembling, the opening fixing block 644 only needs to be pulled out upwards, which is convenient to operate.

[0099] like Figure 8 As shown, in order to make the forming of the bag-making film 10 more stable, a third plastic film part 67 can be arranged between the second plastic film part 64 and the side sealing mechanism 65, and the third plastic film part 67 includes a first side forming plate 91 and a second side forming plate 92 which are staggered on the left and right. The bag-making film 10 formed by the second plastic film part 64 then enters the third plastic film part 67, so that the bag-making film 10 abuts against the four corners of the plastic film core 63, and strengthens the four edges formed in the end; the side sealing part formed by the second plastic film part 64 enters between the first side forming plate 91 and the second side forming plate 92, so that the side sealing part is in the same direction as the surface where it is located.

[0100] Preferably, if Fig. 9As shown, the side sealing mechanism 65 includes a side sealing block 651, and the side sealing block 651 is connected to a side sealing driving mechanism 652 arranged horizontally. A heating wire is arranged inside the side sealing block 651, which can heat the sealing surface of the side sealing block 651; the side sealing driving mechanism 652 can be a linear motor, a cylinder or a guide rail slider mechanism driven by a motor arranged horizontally, or a connecting piece connected to the bottom sealing mechanism as shown in this embodiment. By connecting the side sealing block 651 to the symmetrical driving mechanism of the bottom sealing mechanism 7, it moves synchronously with the bottom sealing block 71, thereby reducing the number of driving components. The side second forming plate 92 located on the inner side also extends downward to the side sealing mechanism 65. When the side sealing block 651 seals the side sealing part by heat, the side second forming plate 92 is located between the side sealing part and the medicine bag body. The heated side sealing block 651 presses the sealing part against the side second forming plate 92 to complete the sealing of the side of the medicine bag.

[0101] Combination Fig. 9 A side view of the side sealing mechanism, the bottom sealing mechanism and the breaking mechanism of the present invention; Fig.10 An axonometric view of the side sealing mechanism, the bottom sealing mechanism and the breaking mechanism of the present invention; and Fig.11 Bottom view of the side sealing mechanism, bottom sealing mechanism and separating mechanism of the present invention. After the bag-making film 10 passes through the side sealing mechanism 65, it needs to enter the bottom sealing mechanism 7 to complete the bottom sealing process of the medicine bag. The bottom sealing mechanism 7 includes a symmetrically arranged bottom sealing block 71, and the separating mechanism 8 includes a scissors 81. The bottom sealing block 71 and the scissors 81 are both connected to a symmetrical driving mechanism. The symmetrical driving mechanism includes a guide rail 72, a slider 73, a fisheye bearing 74, a connecting piece 75, a crank 76 and a first motor 77; the guide rail 72 is fixed on a frame 78, and the slider 73 is arranged on the guide rail 72 and can slide freely along the guide rail 72; the connecting piece 75 is hinged on the frame 78 and is hinged to the slider 73 through the fisheye bearing 74; the connecting piece 75 is also provided with a slot 751, and the first motor 77 is connected to the crank 76, and one end of the crank 76 extends into the slot 751. The symmetrical driving mechanism can simultaneously drive the bottom sealing block 71 and the scissors 81, simplifying the overall structure of the machine and improving operational reliability. In addition, the symmetrical driving mechanism has a compact structure and can drive the two arms of the bottom sealing block 71 and the scissors 81 to move synchronously toward each other, simplifying the process while ensuring the quality of sealing and shearing.

[0102] 2. Medicine bag control mechanism

[0103] The turntable moving mechanism 1 of the medicine bag manipulation mechanism is used to drive the turntable 2 to move, so as to facilitate the switching of the turntable 2 between different workstations, so that the bagging, unloading and sealing processes can be carried out simultaneously, thereby improving the efficiency of medicine dispensing. The turntable moving mechanism 1 can drive the turntable 2 to move linearly or to rotate, which is specifically set according to actual needs. In this embodiment, the turntable moving mechanism 1 drives the turntable to rotate.

[0104] According to a specific embodiment of the present invention, Figure 12-Figure 18 The turntable moving mechanism 1 includes a turntable rotating mechanism 11 and a turntable mounting member 12 connected to the turntable rotating mechanism 11. The turntable rotating mechanism 11 is used to drive the turntable mounting member 12 to rotate, thereby realizing the switching of the turntable 2 between different workstations. Fig.16 As shown, it includes a turntable motor 111, a turntable synchronous belt 112 connected to the turntable motor 111, and a turntable gear 113 connected to the turntable synchronous belt 112, wherein the turntable gear 113 is fixedly connected to the turntable mounting member 12, so when the turntable motor 111 is working, it drives the turntable synchronous belt 112 and the turntable gear 113 to move, and the turntable gear 113 drives the turntable mounting member 12 to rotate, thereby realizing the rotation of the turntable mounting member 12.

[0105] Preferably, at least two turntable mounting positions are provided on the turntable mounting member 12, and the turntable 2 is installed on the turntable mounting positions. Therefore, when the turntable mounting member rotates, the turntable 2 is driven to move together, thereby realizing the switching of the turntable 2 between different workstations.

[0106] The turntable 2 is arranged on the turntable mounting member of the turntable moving mechanism 1, and the number thereof is preferably at least two, so as to realize the synchronous operation of at least two processes and improve the efficiency of drug dispensing. Fig.13 As shown, the turntable 2 includes a batching disk rotating mechanism 21, a batching disk 22 arranged on the batching disk rotating mechanism 21, and a plurality of fixing frames 23 arranged on the batching disk 22. The batching disk rotating mechanism 21 is used to drive the batching disk 22 to rotate, ensuring that multiple medicine bags can complete the operation of corresponding processes in sequence.

[0107] Specifically, Fig.17 As shown, the batching disk rotating mechanism 21 includes a batching disk motor 211, a batching disk synchronous belt 212 connected to the batching disk motor 211, and a batching disk gear 213 connected to the batching disk synchronous belt 212, wherein the batching disk gear 213 is connected to the batching disk 22, so when the batching disk motor 211 is working, the batching disk synchronous belt 212 and the batching disk gear 213 rotate under the action of the batching disk motor 211, thereby driving the batching disk 22 to rotate.

[0108] Preferably, as Fig.15 shown, the batching tray 22 is circular, and is provided with a plurality of mounting openings 24 thereon. The plurality of mounting openings 24 are evenly distributed along the circumferential direction of the batching tray 22. The fixing frame 23 is fixed to the batching tray 22 through the mounting openings 24, so that the fixing frames 23 can be evenly distributed along the circumferential direction of the batching tray 22, which is convenient for mechanized control.

[0109] More preferably, the mounting opening 24 has an axisymmetric structure, and the shape and size thereof are adapted to the shape and size of the fixing frame 23. It includes an arc-shaped structure bent outward and a U-shaped structure connected to the arc-shaped structure. The U-shaped structure is located at both ends of the arc-shaped structure.

[0110] As Fig.18 shown, in order to facilitate blanking and improve the blanking efficiency, the mounting opening 24 is inclined on the batching tray 22. Specifically, the center line of the U-shaped structure of the mounting opening 24 forms an intersection with the edge of the batching tray 22, and the included angle a between the tangent line passing through this intersection and this center line, the included angle a > 0° and < 90°. Preferably, the included angle a is 10° - 60°, so that the blanking mechanism 100 can better align with the fixing frame, which is convenient for blanking and improves the distribution density of the mounting openings at the same time.

[0111] As Figure 19-20 shown, the fixing frame 23 is arranged inside the mounting opening 24, and its shape and size match the shape and size of the mounting opening, which is convenient for placing a plurality of medicine bags, so as to realize that a plurality of medicine bags sequentially complete corresponding operations. In this embodiment, the fixing frame 23 includes a body 231, a first opening 232 arranged at the top of the body 231, a receiving cavity 233 arranged inside the body 231 and communicating with the first opening 232, and a second opening 234 arranged at the bottom of the body 231. The receiving cavity 233 includes a medicine bag cavity 23a for receiving medicine bags and a positioning cavity 23b. The positioning cavity 23b is arranged at both ends of the medicine bag cavity 23a and communicates with the medicine bag cavity 23a.

[0112] Wherein, the width of the medicine bag cavity 23a gradually decreases from the top to the bottom, and the width of the central area on the same horizontal plane is greater than the width of its two sides; the width of the positioning cavity 23b is equal to the minimum width of the medicine bag cavity 23a, and both sides of the medicine bag extend into the positioning cavity 23b.

[0113] The shape and size of the first opening 232 are matched with the shape and size of the installation opening 24, and it is embedded in the installation opening 24. In order to facilitate the detachable connection between the fixing frame 23 and the ingredient tray 22 and to facilitate cleaning, etc., the edge of the first opening 232 is provided with an outwardly extending fixing strip 235. When installed, the fixing strip 235 abuts against the upper surface of the ingredient tray 22, thereby realizing the connection between the fixing frame 23 and the ingredient tray 22, and the disassembly and assembly are convenient and quick, and easy to maintain.

[0114] The second opening 234 extends upward from the bottom of the body 231, so that two fixed feet 236 are formed at the bottom of the body 231 to support the body 231 and the medicine bag, ensuring that the external mechanism can smoothly apply force or detect the medicine bag, thereby ensuring the smooth progress of the dispensing process.

[0115] 3. Medicine bag sealing mechanism.

[0116] Combination Fig.21 and Fig. 22 The medicine bag sealing mechanism 300 includes a sealing assembly 3 for sealing the bagged Chinese medicine, a displacement assembly 4 for driving the sealing assembly 3 to translate, and a lifting assembly 5 for driving the bagged Chinese medicine to lift; the sealing assembly 3 includes a first guide rail 31, a first slider 32, a second slider 33, a first heating block 34, a second heating block 35, and a slider driving mechanism 36; the first slider 32 and the second slider 33 are arranged on the first guide rail 31; the first heating block 34 is arranged on the first slider 32, and the second heating block 35 is arranged on the second slider 33; the slider driving mechanism 36 is used to drive the first slider 32 and the second slider 33 to slide toward each other along the first guide rail 31; the lifting assembly 5 includes a lifting block 51 and a lifting block driving mechanism 52, and the upper end of the lifting block 51 is provided with a bayonet 511, and preferably, the cross section of the bayonet 511 is V-shaped. The lifting block driving mechanism 52 is used to drive the lifting block 51 to move up and down.

[0117] With the medicine bag sealing mechanism 300, the lifting assembly 5 can support the bottom of the packaging bag and push it upward, and the bayonet 511 can position the medicine bag during the rising process of the packaging bag to prevent the medicine bag from rotating and ensure that the medicine bag has a uniform orientation when it is sealed. The first heating block 34 and the second heating block 35 move toward each other under the drive of the first slider 32 and the second slider 33, and can gradually press the bag opening toward its center, and fit it tightly by hot melting to ensure the sealing quality.

[0118] Combination Fig.23As shown, the lifting block driving mechanism 52 includes a lifting rod 521, a linear bearing 522, a synchronous belt 523 and a third motor 524. The lifting rod 521 is sleeved in the linear bearing 522, and the top is connected to the lifting block 51; the lower part of the lifting rod 521 is connected to the synchronous belt 523, and the third motor 524 drives the synchronous belt 523 to move, thereby driving the lifting rod 521 to extend or retract vertically.

[0119] After being lifted by the lifting assembly 5, the packaging bag as a whole has a certain amount of space for movement, which makes the position of the bag opening change within a certain range. Therefore, the first heating block 34 and the second heating block 35 must be able to move towards each other sensitively and quickly, straighten the bag opening and gradually compress it until it is completely fitted. For this purpose, the present application designs a special slider driving mechanism 36. Fig. 22 As shown, the slider driving mechanism 36 includes a slider fixing frame 361, a first motor 362, a crank 363, a linkage 364, a first fisheye bearing 365 and a second fisheye bearing 366; the linkage 364 is hinged to the slider fixing frame 361 through a hinge point 369, and is connected to the first slider 32 through the first fisheye bearing 365, and is connected to the second slider 33 through the second fisheye bearing 366; a slide groove 367 is also provided on the linkage 364, and a needle bearing 368 is provided at one end of the crank 363, and the needle bearing 368 is arranged in the slide groove 367. The needle bearing 368 can slide in the slide groove 367; the first motor 362 can drive the linkage 364 to rotate through the crank 363, thereby driving the first slider 32 and the second slider 33 to move toward each other. Typically, the first fisheye bearing 365 and the second fisheye bearing 366 have the same specifications and the connection position with the linkage member 364 should be on the same diameter circumference of the hinge point between the linkage member 364 and the slider fixing frame 361 to achieve the same speed movement of the first slider 32 and the second slider 33.

[0120] As mentioned above, since the weight of the Chinese medicine granules loaded into the above-mentioned Chinese medicine granule packaging bag each time is different, the free space at the bag mouth before the medicine bag is sealed also varies greatly. For example, sometimes the Chinese medicine granules only occupy one-third of the space of the medicine bag, and sometimes they occupy three-quarters. If a simple sealing technology is used for different loading ratios, the medicine bag is prone to contain too much air when the loading amount is small, which is easy to affect the shelf life of the medicine, and the bulging medicine bag is also easy to be compressed and damaged; when the loading amount is large, the Chinese medicine granules are easy to run to the sealing position, affecting the sealing reliability. For this reason, the first shaping piece is also provided on the first slider 32 in this embodiment, and the second shaping piece is also provided on the second slider 33. The first shaping piece includes a side plate 37 and a first pressing plate 38, and the side plate 37 extends from both sides of the front of the first pressing plate 38; the second shaping piece includes a second pressing plate 39, and the first pressing plate 38 and the second pressing plate 39 are arranged opposite to each other. The side plate 37 contacts both sides of the bag mouth to straighten the bag mouth. During the sealing process, the first pressing plate 38 and the second pressing plate 39 abut against the first heating block 34 and the second heating block 35 before pressing against the first heating block 34 and the second heating block 35, and the air in the packaging bag is pressed out. If there are already Chinese medicine particles at the pressing position, they are gradually tightened upwards, and the Chinese medicine particles are slightly pressed downwards during the process of pressing the opening. After the sealing is completed, the first heating block 34 and the second heating block 35 are separated before the first pressing plate 38 and the second pressing plate 39. The first pressing plate 38 and the second pressing plate 39 fix the medicine bag to prevent the medicine bag from sticking to the first heating block 34 or the second heating block 35, so as to facilitate automatic discharging.

[0121] After the sealing is completed, the displacement component 4 drives the medicine bag to move horizontally to the discharge port to achieve automatic discharge. Fig.24 As shown, the displacement assembly 4 includes a second guide rail 41, a translation slider 42, a translation fixed seat 43 and a translation slider driving mechanism 44; the second guide rail 41 is mounted on the translation fixed seat 43; the translation slider driving mechanism 44 is used to drive the translation slider 42 to move along the second guide rail 41; the translation slider 42 is connected to the slider fixing frame 361. The translation slider driving mechanism 44 can be a cylinder, a linear motor, or a rocker mechanism 46 driven by a motor 45 that can drive the translation slider 42 to move linearly.

[0122] Preferably, in order to avoid a rigid collision between the first heating block 34 and the second heating block 35, the first clamping plate 38 and the second clamping plate 39 when they are close to each other, the first heating block 34, the second heating block 35, the first clamping plate 38 and the second clamping plate 39 are all connected to an elastic buffer mechanism (not shown in the figure). Specifically, the elastic buffer mechanism can be a spring, and the first heating block 34, the second heating block 35, the first clamping plate 38 and the second clamping plate 39 are all connected to the first slider 32 or the second slider 33 through corresponding guide pillars, and a spring is inserted outside the guide pillar, and the first heating block 34, the second heating block 35, the first clamping plate 38 and the second clamping plate 39 are connected to the corresponding first slider 32 or the second slider 33 through the spring, so that the first heating block 34, the second heating block 35, the first clamping plate 38 and the second clamping plate 39 have a certain buffer space when encountering resistance.

[0123] The working principle of this embodiment is as follows:

[0124] 1. Bag making. Since two batching trays are provided in this embodiment, after one batching tray has finished bag making, this batching tray moves to the unloading station for unloading. At this time, the other batching tray can move to the bag making station to continue bag making, so as to carry out continuous unloading work and improve work efficiency.

[0125] The rolled bag-making film 10 is stored in the film storage mechanism 61, and can be rotated and discharged under the traction of the bag-making film 10. The bag-making film 10 enters the first plastic film member 62 under the guidance of the guide roller, and the two edges of the bag-making film 10 enter the guide surface 621, and move closely along the guide surface 621 under the limiting action of the limiting strip 623, changing from a flat sheet to a ring shape, and wrapped on the long plastic film core 63.

[0126] Next, the bag-making film 10 enters the second plastic film member 64, and the bag-making film 10 is further pressed against the plastic film core 63 under the gathering effect of the outer guide slope 647 of the annular guide member 641, and the bag-making film 10 begins to imitate the shape of the plastic film core 63 to form four edges. The two side edges of the bag-making film 10 begin to overlap under the guidance of the side sealing guide slope 648 to form a side sealing part, and the side sealing part is transported downward through the side sealing opening 642.

[0127] After leaving the second plastic film part 64, the bag-making film 10 enters the third plastic film part 67, which is also arranged around the plastic film core 63, so that the bag-making film 10 can abut against the four corners of the plastic film core 63, thereby strengthening the four edges finally formed; in addition, the side sealing part enters between the side first forming plate 91 and the side second forming plate 92 which are staggered on the left and right, so that the side sealing part changes from being perpendicular to the surface where it is located to being in the same direction as the surface where it is located;

[0128] After being molded again by the third plastic film part 67, the bag-making film 10 enters the side sealing mechanism 65, where the side sealing block 651 extends toward the side sealing portion of the bag-making film 10 and cooperates with the side second molding plate 92 to seal the side sealing portion.

[0129] After the bag-making film 10 passes through the side sealing mechanism 65, it needs to enter the bottom sealing mechanism 7 to complete the bottom sealing process of the medicine bag. Here, the first motor 77 of the symmetrical driving mechanism drives the crank 76 to rotate, and then drives the connecting member 75 to rotate around its own hinge axis, driving the fisheye bearing 74 to move, and the slider 73 on the guide rail 72 to move synchronously through the fisheye bearing 74. The bottom sealing block 71 provided on the slider 73 seals the bottom of the bag-making film 10.

[0130] The bag-making film 10 that has completed the bottom sealing process continues to move downward under the drive of the film driving mechanism 66 and enters the fixed frame 23 directly below it. The fixed frame 23 has a specially designed accommodating cavity 233, and the accommodating cavity 233 contacts the four edges of the medicine bag. In the process of the bag-making film 10 entering the fixed frame 23, the medicine bag maintains a tendency to open. After the bag-making film 10 drops to a predetermined position, the sliders 73 of the symmetrical driving mechanism approach each other again, and the scissors 81 cut the medicine bag and the upper bag-making film 10. At the same time, the upper bag-making film 10 completes the bottom sealing process, waits for the ingredient plate 22 to rotate to a predetermined angle, aligns the other fixed frame 23 with the bottom sealing mechanism, and continues to make the medicine bag.

[0131] Since the fixing frame 23 needs to have the function of positioning the position and shape of the medicine bag, the medicine bag needs to abut against the inner wall of the fixing frame 23. Since the weight of the medicine bag is relatively light, the weight of the medicine bag alone cannot overcome the friction between the medicine bag and the fixing frame 23 and automatically enter the predetermined position of the fixing frame 23. Using the above structure, in the process of bag making, after the side and bottom of the medicine bag are sealed, the film driving mechanism 61 is used to transmit the overall force of the bag-making film 10 to extend the medicine bag into the fixing frame 23, and finally the medicine bag is cut and separated from the upper bag-making film 10. After cutting, the medicine bag keeps its opening open under the action of its own four edges and the inner wall of the fixing frame 23, ensuring that the subsequent medicine can completely enter the medicine bag without any additional means and structure to open the medicine bag.

[0132] 2. Unloading. The medicine bottles carrying different Chinese medicine granules are arranged on the shelf on one side of the automatic unloading and sealing device for Chinese medicine granules, similar to the placement of traditional Chinese medicine cabinets. When unloading is needed, the dispensing staff can manually take the corresponding medicine bottle, put it into the unloading port 101, and add a predetermined amount of Chinese medicine granules into the medicine bag. Preferably, in order to improve the accuracy and automation level of unloading, the medicine bottle can adopt the existing special medicine bottle with an automatic metering mechanism, and the unloading port 101 is provided with an automatic metering mechanism driving device. The control system calculates the volume required for unloading according to the weight and preset density of the Chinese medicine granules to be unloaded; when the automatic metering mechanism of the medicine bottle extends into the unloading port 101, the automatic metering mechanism driving device will drive the automatic metering mechanism to measure the predetermined volume of Chinese medicine granules in the medicine bottle, and drop them into the medicine bag directly below it by gravity. In order to ensure that the amount of material discharged is accurate and reliable, a weighing mechanism 102 can also be set up. Before discharging, the medicine bottle is placed in the weighing mechanism 102 for material quantity monitoring, and then placed in the discharge port 101 to add a predetermined amount of Chinese medicine particles into the medicine bag.

[0133] The bag making mechanism 400 places the prepared medicine bag into the fixed frame 23, the ingredient disk 22 rotates to the position of an installation port, and then places a new medicine bag in the next fixed frame 23 until a preset number of medicine bags are installed. The turntable rotating mechanism 11 drives the turntable 2 to rotate until the ingredient disk 22 with the medicine bag is located under the unloading mechanism 100. After the unloading mechanism 100 completes the unloading of one medicine bag, the ingredient disk rotating mechanism 21 drives the ingredient disk 22 to rotate to the position of an installation port 24 to unload the next medicine bag until the preset number of medicine bags are installed.

[0134] 3. Sealing. After the medicine bag is loaded with the Chinese medicine granules, the turntable rotating mechanism 11 drives the turntable 2 to rotate again, and cooperates with the rotation of the ingredient plate 22 to deliver the medicine bag that currently needs to be sealed to the top of the lifting component 5, and the lifting component 5 and the sealing component 3 are directly opposite each other. At this time, the lifting component 5 drives the lifting block 51 to rise, and the latter supports the bottom of the medicine bag through its bayonet 511, and pushes it upward from the fixed frame 23. During the ejection process, the positioning cavity 23b of the fixed frame 23 continuously guides the medicine bag until it is lifted to the predetermined position of the sealing component 3. Subsequently, the slider driving mechanism 36 drives the first slider 32 and the second slider 33 to move toward each other, and the sealing action begins. During the sealing process, the side plate 37 first contacts the medicine bag, which gently contacts the two sides of the medicine bag to prevent the medicine bag from tilting. Then the first pressing plate 38 and the second pressing plate 39 begin to contact the central height position of the medicine bag and gradually compress it toward each other. If the compression position is already filled with Chinese medicine particles, since the first pressing plate 38 and the second pressing plate 39 both have elastic margins, the pressing surfaces of the first pressing plate 38 and the second pressing plate 39 are slightly tilted, so that the medicine bag forms a central bulge and gradually fits from the center to the opening position; finally, the first heating block 34 and the second heating block 35 press and heat the predetermined sealing position near the opening of the medicine bag to perform the sealing work.

[0135] 4. Discharging. After the sealing is completed, the displacement component 4 drives the sealing component 3 to move horizontally as a whole, and drives the medicine bag to move to the discharging station. Then the first slider 32 and the second slider 33 move away from each other, and the first heating block 34 and the second heating block 35 are first separated from the medicine bag. Then the first pressing plate 38 and the second pressing plate 39 are separated from the medicine bag, and the medicine bag falls into the discharging station due to gravity. The discharging station can be a simple discharging port, and the operator manually takes the sealed medicine bag from the discharging port; it can also be a discharging transmission line, through which the sealed medicine bag is transported to a predetermined temporary storage position, and then discharged after all packaging is completed.

[0136] In summary, the quantitative preparation device of Chinese medicine granules of the present invention integrates a bag making mechanism, a feeding mechanism, a medicine bag control mechanism and a medicine bag sealing mechanism, and has a simple structure and a small size. Through the cooperation of the bag making mechanism, the feeding mechanism, the medicine bag control mechanism and the medicine bag sealing mechanism, the bag is made in real time on site. After the medicine bag is made, the opening is opened to form a cavity inside, and then the medicine bag is placed in the fixed frame of the medicine bag control mechanism in an open state; then different medicines are placed in the medicine bag according to the corresponding prescription through the feeding mechanism; the medicine bag after feeding is transferred as a whole to the medicine bag sealing mechanism for sealing, and the medicine bag is automatically used on site to prepare medicines and package and seal according to the doctor's prescription.

[0137] The entire Chinese medicine granule preparation process is quiet, fast, safe, sanitary and pollution-free;

[0138] The prepared bagged Chinese medicine is small in size, low in cost, and easy to carry;

[0139] The size and quantity of medicine bags can be made in real time according to the patient's prescription information, realizing customized services for patients;

[0140] The quantitative preparation equipment for Chinese medicine granules realizes the miniaturization and integration of Chinese medicine granule preparation, and can also realize the intelligent preparation of Chinese medicine granules.

[0141] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
