Description

Technical Field

[0001] The invention relates to the field of production of granular products, and in particular to a dispensing system for granular products. Background Art

[0002] Granular products refer to items in the form of granules, such as granular preparations in medicines and condiments. Dispensing refers to the process of quantitatively adding granular products from a larger container to a packaging bag. Before and after dispensing, a large number of other operations need to be performed, such as the production of packaging bags, the transportation of packaging bags, the sealing of packaging bags, and the dropping of packaging bags.

[0003] At present, the general operation process of adjusting the granular products is: first, the packaging bag is produced, then the mouth of the packaging bag is opened and maintained, then the granular products in the medium-volume bottle storing the granular products are adjusted into the packaging bag, and finally the packaging bag is sealed and put into the bag.

[0004] Among them, blending is an important link, and the volumetric flasks and bottle caps in the current dispensing equipment are transported by manually taking and inserting them into the equipment for positioning, and they also need to be manually pulled out and taken away after the blending is completed.

[0005] The operator can only plug in and out one volumetric bottle at a time, and the plugging and unplugging of the volumetric bottle has high positioning and direction requirements. This process has low work efficiency, high labor intensity, and requires accurate positioning, which puts high demands on the operator's skills. However, during the operation, the wrong direction often occurs, and there are many operating errors. This not only reduces work efficiency, but also affects the connection with subsequent automation devices.

[0006] In addition to the above-mentioned drawbacks, the current dispensing system also has the problem that most of the functional devices (such as bag making device, bottle storage device, material bottle transmission device, sealing bag device and packaging bag rotation device) are operated independently. After completing the corresponding operation, each functional device still needs manual or other machines (such as robot arms) to perform the next operation. It is difficult to automatically connect between the workstations, which leads to low production efficiency. More importantly, there are often operational jams between the workstations, which greatly further reduces production efficiency. Summary of the invention

[0095] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0096] The present invention provides a dispensing system for granular products, such as Figure 1-2As shown, the dispensing system includes: a bag making device 4, a bottle storage device 1, two material bottle transmission devices 5, two dispensing driving devices 2, a sealing bag dropping device 6 and a packaging bag rotating device 7; the bottle storage device 1 is respectively connected to the two material bottle transmission devices 5 so as to be able to provide material bottles 3 to the material bottle transmission devices 5; the two material bottle transmission devices 5 are located on both sides of the packaging bag rotating device 7, and the packaging bag rotating device 7 is an annular conveying structure, and the packaging bag rotating device 7 can allow a fixed packaging bag 411 to pass under the material bottle transmission device 5; the dispensing driving device 2 is located on the outside of the material bottle transmission device 5 so as to be able to dispense the granular product in the material bottle 3 into the packaging bag 411; the sealing bag dropping device 6 is located on one side of the packaging bag rotating device 7 so as to be able to top-seal the adjusted packaging bag 411; the bag making device 4 is located under the packaging bag rotating device 7 so as to be able to provide the packaging bag 411 to the packaging bag rotating device 7.

[0097] In the present invention, the specific structure of the packaging bag rotating device 7 can have various forms, but in order to enable the packaging bag fixing mechanism 41 to be continuously and stably connected with the material bottle conveying device 5 and the bag making device 4, preferably, as Figure 5 As shown, the packaging bag rotating device 7 includes a first driving motor 81, an annular rotating mechanism 82 and a packaging bag fixing mechanism 41, on which at least two packaging bags 411 with open tops are fixed; at least two packaging bag fixing mechanisms 41 are arranged outside the annular rotating mechanism 82; the first driving motor 81 can drive the annular rotating mechanism 82 to rotate in an annular manner, so that the packaging bag 411 passes under the material bottle transmission device 5, and can also make the packaging bag fixing mechanism 41 located at the top of the bag making device 4. Therefore, under the driving action of the first driving motor 81, the annular transmission mode of the annular rotating mechanism 82 can enable the packaging bag fixing mechanism 41 to cyclically pass through the bag making device 4 and the material bottle transmission device 5, thereby realizing the seamless connection of the packaging bag 411 between the three stations, thereby improving the production efficiency.

[0098] In the present invention, the specific structure of the packaging bag fixing mechanism 41 can have various forms, but in order to facilitate the fixing and bagging of the packaging bag 5, preferably, as shown in FIG. Fig. 20As shown, the packaging bag fixing mechanism 41 includes a detachable fixed frame 415 and a movable frame 412, at least two chambers are formed between the fixed frame 415 and the movable frame 412 to accommodate the packaging bag 411, and the chamber is provided with a guide groove 414 on the side wall of the fixed frame 415, and the side seal edge of the packaging bag 411 can be fixed in the guide groove 414. Therefore, as long as the side seal edge of the packaging bag 5 is moved along the guide groove 31 into the chamber, the efficiency of the packaging bag 5 entering the chamber is improved, and at the same time, the side seal edge of the packaging bag 5 can be fixed in the guide groove 31 to improve the stability of the fixation. The fixed frame 14 and the movable frame 15 are arranged in a detachable manner, which can greatly improve the convenience of putting the packaging bag 5 into the bag.

[0099] In the above-mentioned embodiment, there are also various ways to fix the side seal of the packaging bag 411, such as fixing it by a latch, but for the convenience of operation, preferably, a clamping member 413 is provided on the outer wall of the fixing frame 415, and the clamping member 413 can clamp the side seal of the packaging bag 411 in the guide groove 414; thus, the side seal of the packaging bag 411 and the guide groove 414 can be separated by pressing the clamping member 413, and in a natural state, the clamping member 413 can clamp and fix the side seal of the packaging bag 411 in the guide groove 414.

[0100] In the above embodiment, the connection method between the fixed frame 415 and the movable frame 412 can also have various forms, but considering the convenience of operation, preferably, the fixed frame 415 and the movable frame 412 are connected by a driving rod 416, and the end of the driving rod 416 extends to the outside of the fixed frame 415 and is connected to the bag dropping mechanism 96 in the sealing and bag dropping device 6, so that the movable frame 412 can approach or move away from the fixed frame 415.

[0101] At present, in the present invention, although the specific structure of the bag making device is not specifically limited, the bag making devices currently on the market generally have the defects of requiring a dedicated former, occupying a large space and having a complex structure; in order to solve this defect, preferably, as Figure 3-4As shown, the bag making device 4 includes an inner former 44, an outer former 46 and a cutting and transverse sealing bag making mechanism 42 which are arranged in sequence from bottom to top; the packaging bag fixing mechanism 41 can be located above the cutting and transverse sealing bag making mechanism 42; the folded film 49 can be vertically covered on the outside of the inner former 44, and the side of the inner former 44 is provided with a vertical sealing mechanism 43, and the vertical sealing mechanism 43 can seal the two side edges of the folded film 49 to form a tubular film; the side of the outer former 46 is provided with a film pulling mechanism 45, and the film pulling mechanism 45 can clamp the side seal edge of the tubular film and drive the tubular film to reciprocate in the vertical direction; the packaging bag fixing mechanism 41 can fix the top of the tubular film; the cutting and transverse sealing bag making mechanism 42 can transversely seal and cut the tubular film between the packaging bag fixing mechanism 41 and the outer former 46, so that the tubular film in the packaging bag fixing mechanism 41 forms a packaging bag 411.

[0102] The working process of the above-mentioned bag making device 4 is as follows: first, the folded film 49 is initially fixed in shape by the inner former 44; then, the vertical sealing mechanism 43 seals the two sides of the folded film 49 on the inner former to form a tubular film; then, the outer former 46 and the film pulling mechanism 45 cooperate to make the tubular film move upward, thereby providing power for the movement of the folded film 49 below; after traction, the tubular film enters the packaging bag fixing mechanism 41 for fixing; finally, the tubular film between the packaging bag fixing mechanism 41 and the outer former 46 is horizontally sealed and cut by cutting the transverse sealing bag making mechanism 42, so that the semi-formed packaging bag 411 is fixed to the packaging bag fixing mechanism 41; in addition, the packaging bag can be directly filled in the packaging bag fixing mechanism 41, and finally the top is sealed to complete the packaging process of the items.

[0103] Compared with the prior art, this embodiment has the following beneficial effects:

[0104] 1. The shapes of the inner former 44 and the outer former 46 do not need to be specifically designed, so that the application scope of the bag-making device is expanded and the cost of the device is reduced.

[0105] 2. All functional components are integrated into the same device, which greatly reduces the size of the device and reduces the occupied space.

[0106] 3. The device can work in conjunction with the filling device to complete the one-stop operation of bag making and packaging, greatly improving production efficiency.

[0108] In the above embodiment, the sealing method of the vertical sealing mechanism 43 can be selected within a wide range, but in order to further improve the sealing effect, preferably, the vertical sealing mechanism 43 uses an electric heating element for heat sealing.

[0109] In the present invention, the method of providing the folded film 49 can also be selected within a wide range, but in order to achieve stable and continuous supply of raw materials, preferably, the folded film 49 is provided by a folded film roll 47, and a guide wheel 48 is provided between the folded film roll 47 and the inner former 44, and the folded film 49 is wound around the outside of the guide wheel 48.

[0110] In the present invention, the specific structure of the material bottle transmission device 5 can be selected in a wide range, but the existing material bottle transmission devices generally have the defects of low working efficiency, high error rate, bottle jamming and large equipment size. In order to solve this defect, preferably, as Figure 6 As shown, the material bottle transmission device 5 includes a transmission mechanism, an adjusting mechanism and two weighing and checking devices 12; the transmission mechanism can drive the material bottle 3 to reciprocate along a straight line, the transmission mechanism is provided with an adjusting station, the adjusting station is provided with at least two drop holes 116, and the adjusting mechanism is arranged on one side of the adjusting station; when the material bottle 3 passes through the adjusting station, the adjusting mechanism can fix the material bottle 3, and drive the material bottle 3 to open so that the granular product falls from the drop hole 116 into the packaging bag 411; the two weighing and checking devices 12 are respectively arranged at both ends of the transmission mechanism, so as to be able to weigh and check the weight of the material bottle 3 before and after the adjustment.

[0111] In this embodiment, first, the material bottle 3 is weighed by the weighing and calibration device 12 at one end of the transmission mechanism. After the weighing is completed, the material bottle 3 is transmitted to the other end of the transmission device through the transmission mechanism. When passing through the drop hole 116 of the adjustment station, the adjustment device starts to open the material bottle 3 at this time, so that the granular material in the material bottle 3 falls from the drop hole, completing the adjustment action; after the adjustment is completed, the adjustment mechanism is separated from the material bottle 3. At this time, the material bottle 3 continues to move to the other end of the transmission mechanism, until the medicine bottle is transmitted to another weighing and calibration device for calibration of the weight of the material bottle 3.

[0112] Compared with the prior art, this embodiment has the following beneficial effects:

[0113] 1. The material bottle transmission device 5 realizes automated operation, and there is no need to manually plug and unplug the material bottle 3, thereby reducing the error rate and improving work efficiency;

[0114] 2. The material bottle 3 is smoothly transferred during the process of bearing, conveying and checking, avoiding the occurrence of the phenomenon of the material bottle 3 being stuck;

[0115] 3. The material bottle transmission device 5 is generally linear, and has no restriction on the number of adjustment parts, thereby effectively reducing the volume of the equipment.

[0116] In the above embodiment, the specific structure of the material bottle 3 can be selected in many ways, as long as the bottle cap of the material bottle 3 can realize automatic metering and material dropping when driven by external force, such as a porous metering device for granular preparation disclosed in patent document No. CN 110589037A.

[0117] In the above embodiment, the specific structure of the adjusting mechanism can be selected within a wide range, but in order to further improve the flexibility of the adjusting mechanism for the material bottle 3 during the adjusting process, preferably, as Figure 7-9 As shown, the adjusting mechanism includes a plurality of adjusting units, and the outer side of each drop hole 116 is correspondingly provided with the adjusting unit, and each of the adjusting units includes: a fixed plate 131 and a first movable plate 135; the first movable plate 135 is arranged on the top of the fixed plate 131, and is connected to the clutch driving mechanism so that the first movable plate 135 can reciprocate relative to the fixed plate 131; the top of the first movable plate 135 is provided with a first driving gear 137 and a second driving gear 136 that mesh with each other, and the second driving gear 136 is connected to an adjusting driving unit 138 to drive the second driving gear 136 to rotate, and the outer edge of the first driving gear 137 extends to the outside of the first movable plate 135; when the material bottle 3 passes through the adjusting station, the first driving gear 137 can mesh with the gear on the outer periphery of the material bottle 3 to drive the material bottle 3 to open so as to drop the granular product from the drop hole 116.

[0118] Through this adjustment mechanism, as long as the material bottle 3 is about to pass over each of the drop holes 116, the clutch drive mechanism starts working, thereby driving the first movable plate 135 to approach the material bottle transmission device 5, until the first drive gear 137 is meshed with the gear on the outer periphery of the material bottle 3 (generally, it is meshed with the gear on the outer periphery of the bottle cap of the material bottle 3). At this time, the adjustment drive unit 138 is also in a working state, and the first drive gear 137 is driven by the rotation of the second drive gear 136, thereby indirectly driving the material bottle 3 to perform metering and dropping, and the medicine is then dropped. After the adjustment is completed, the clutch drive mechanism can drive the first movable plate 135 away from the material bottle transmission device 5, so as to facilitate the material bottle 3 to enter the next material drop hole 116 to complete the adjustment work. It can be seen that in this embodiment, the material bottle 3 can complete multiple adjustment work on the same material bottle transmission device 5, thereby greatly improving the adjustment efficiency; more importantly, the entire process is fully automatic, thereby avoiding various operating errors, device jams and other phenomena, thereby providing another guarantee for efficient production.

[0119] In the above embodiment, the specific structure of the clutch drive mechanism is not specifically limited here, as long as it can drive the first movable plate 135 to reciprocate relative to the fixed plate 131, so as to achieve the purpose of the first movable plate 135 being able to move away from or close to the material bottle conveying device 5. However, in order to consider the convenience of operation, preferably, the clutch drive mechanism includes: a clutch motor 132 and an eccentric wheel 133, the clutch motor 132 is located at the bottom of the fixed plate 131, and the eccentric wheel 133 passes through the fixed plate 131 and is connected to the first movable plate 135. Therefore, as long as the clutch motor 132 is started, the clutch motor 132 can drive the eccentric wheel 133 to reciprocate, so as to achieve the effect of achieving the first movable plate 135 being able to reciprocate relative to the fixed plate 131. The device is not only simple in structure, but more importantly, it is very easy to operate.

[0120] In addition, in the above embodiment, in order to ensure the stability of the adjustment unit during the adjustment process, preferably, a limiting plate 139 is provided on the outer wall of the adjustment drive unit 138, and the limiting plate 139 can limit the material bottle 3. Therefore, during the adjustment process, the first limiting plate 139 stably limits the material bottle 3, thereby effectively preventing the material bottle 3 from tipping over or shaking, thereby improving the adjustment effect.

[0121] In the above embodiment, the specific type of the adjustment drive unit 138 can be selected within a wide range, but in order to further facilitate the driving of the adjustment drive unit 138, preferably, the adjustment drive unit 138 is a motor.

[0122] In the present invention, the specific structure of the transmission mechanism can have various forms. In order to achieve stable and continuous transmission of the transmission mechanism, preferably, the transmission mechanism includes a driving motor 111, two belts 112 and two belt pulleys 113 arranged at intervals; the two ends of the two belts 112 are respectively sleeved on the two belt pulleys 113, and a transmission gap is formed between the two belts 112; the driving motor 111 is connected to one of the belt pulleys 113 to drive the material bottle 3 to move in the transmission gap. Therefore, as long as the driving motor 111 is started, the belt pulley 113 can be driven to rotate, thereby realizing the rotation of the belt 112, and finally realizing the continuous transportation of the material bottle 3.

[0123] The dispensing system is a core component of the Chinese medicine dispensing equipment. In the existing dispensing equipment, the material bottle 3 and the bottle cap need to be manually scanned to confirm the identity information of the material bottle 3. This operation mode greatly limits the transmission efficiency. In order to further improve the recognition efficiency of the material bottle 3, preferably, the transmission mechanism also includes a side plate 114, which is located on the side of the belt 112. The side plate 114 is provided with a plurality of detection antennas 115 matched with the drop holes 116. The detection antenna 115 can identify and confirm the identity information of the material bottle 3 passing through. The setting of the detection antenna 115 can quickly identify and confirm the identity information of the material bottle 3 passing through, thereby effectively improving the work efficiency.

[0124] In the present invention, the installation position and specific structure of the weighing and checking device 12 can also be selected in a wide range. In order to achieve seamless connection between the material bottle 3, the weighing and checking device 12 and the transmission mechanism, preferably, the weighing and checking device 12 is located below the two ends of the transmission mechanism, and the weighing support plate on the weighing and checking device 12 can reciprocate in the vertical direction so as to be able to weigh and check after contacting the bottom of the material bottle 3. Then, as long as the weighing support plate is in contact with the material bottle 3, the weighing sensor can quickly complete the weighing and checking; after the weighing and checking are completed, the weighing support plate descends, thereby achieving the purpose of separating the weighing support plate from the material bottle 3.

[0125] In the present invention, the specific structure of the sealing and bagging device 6 can also be selected in a wide range, but the existing sealing devices generally have technical defects such as multiple actions, slow response time, low sealing efficiency (especially, it is difficult to seal multiple packaging bags at the same time) and complex devices. In order to solve the above-mentioned defects, it is preferred that, as Figure 10-18 As shown, the sealing bag dropping device 6 includes a bag dropping mechanism 96, a driving mechanism 91 and a hot pressing assembly 92; the driving mechanism 91 includes a guide rail frame 97 and a mounting base plate 912; an oblique groove 916 is provided on the mounting base plate 912, and a straight groove 917 is provided at the end of the oblique groove 916; at least one guide rod 98 is horizontally connected to the guide rail frame 97, and the guide rod 98 and the guide rail frame 97 are perpendicular to each other, and a second movable plate 99 is movably connected to the guide rod 98; the second movable plate 99 is connected to the driving unit 93 through a cam assembly 910; a pressing wheel 911 is connected below the second movable plate 99, and the pressing wheel 911 is located in the oblique groove 916 or the straight groove 917; the packaging bag fixing mechanism 41 is located below the mounting base plate 912; at least two hot pressing assemblies 92 are provided below the mounting base plate 912, and the hot pressing assemblies 92 include a heating block 918 and a hot pressing plate 919;

[0126] The driving unit 93 can drive the second movable plate 99 to reciprocate along the guide rod 98; when the pressing wheel 911 is located in the oblique groove 916, the reciprocating movement of the second movable plate 99 can drive the mounting base plate 912 to reciprocate along the length direction of the guide rail frame 97, so that the top of the packaging bag 411 can enter between the heating block 918 and the hot pressing plate 919 for straightening; when the pressing wheel 911 is located in the straight groove 917, the second movable plate 99 can drive the heating block 918 and the hot pressing plate 919 to close, so as to seal the top of the packaging bag 411; the bag dropping mechanism 96 can remove the sealed packaging bag 411 from the packaging bag fixing mechanism 41 of the packaging bag rotating device 7.

[0127] The working process of the above-mentioned sealing bag delivery device 6 is as follows: first, the driving unit 93 is started, and the second movable plate 99 is moved along the guide rod through the transmission of the cam assembly 910, and then the mounting base plate 912 is moved toward the packaging bag fixing mechanism 41 in the packaging bag rotating device 7 through the rotation of the pressing wheel 911 in the oblique groove 916, until each packaging bag 411 enters the hot pressing assembly 92, that is, enters between the heating block 918 and the hot pressing plate 919, thereby realizing the straightening operation of the packaging bag 411; at this time, the second movable plate 99 continues to move along the previous direction on the guide rod 98 until the pressing wheel 911 is located in the straight groove 916, at this time, the pressing wheel 911 has no driving effect on the mounting base plate 912, and the mounting base plate 912 is in a stationary state, and the continued movement of the second movable plate 99 will trigger the closing of the hot pressing assembly 92, that is, trigger the approach between the heating block 918 and the hot pressing plate 919 until a heat seal is formed on the packaging bag 411 between the two. After the heat sealing is completed, the driving unit 93 will complete the reverse rotation, thereby releasing the second movable plate 99 from the contact with the heat pressing assembly 92, that is, the heating block 918 and the heat pressing plate 919 move away from each other; the second movable plate 99 continues to move in the opposite direction, and the pressing wheel 911 enters the oblique groove 917 from the straight groove 916, thereby driving the movement of the mounting base plate 912 again. At this time, the mounting base plate 912 gradually moves away from the packaging bag fixing mechanism 41, thereby facilitating the removal of the packaging bag 411 from the retaining frame.

[0128] Compared with the prior art, this embodiment has the following beneficial effects:

[0129] 1. In a single sealing operation, the device can seal the tops of multiple packaging bags 411 at the same time, as long as the number of packaging bags 411 on the packaging bag fixing mechanism 41 matches the number of hot pressing components 92, thereby greatly improving the sealing efficiency;

[0130] 2. Through a single sealing action, multiple packaging bags 411 can be sealed at the same time, so that the sealing quality remains basically consistent, thereby improving the packaging effect.

[0131] 3. In this device, the straightening operation is completed before heat sealing, thereby avoiding the occurrence of unsatisfactory heat sealing effect, thereby greatly improving the heat sealing qualification rate.

[0132] 4. The device does not require any other device for assistance, has a simple structure, is small in size, and occupies little space.

[0133] In the above embodiment, there are many specific installation methods for the heating block 918 and the hot pressing plate 919 in the hot pressing assembly 92. However, in order to improve the driving effect of the second movable plate 99 on the hot pressing assembly 92, preferably, the hot pressing plate 919 is fixed to the bottom of the mounting base plate 912, and the top of the mounting base plate 912 is provided with a fixing pile 928, and the fixing pile 928 is horizontally connected with a guide connecting rod 929, and the top of the heating block 918 is connected with a heating plate pushing block 925, and the heating plate pushing block 925 is connected to the heating plate pushing block 925. Block 925 passes through the mounting base plate 912 and is sleeved on the guide connecting rod 929, a compression spring 926 is arranged between the fixed pile 928 and the nearest heating plate push block 925, and the top of the heating plate push block 925 is connected to a pressurizing connecting block 924; when the pressing wheel 911 is located in the linear groove 917, the mounting base plate 912 is in a stationary state, and the second movable plate 99 can squeeze the pressurizing connecting block 924 to make the heating block 918 move toward the hot pressing plate 919.

[0134] Therefore, before the pressing wheel 911 enters the linear groove 917, the movement of the mounting base plate 912 is to prepare for the straightening operation until the packaging bag 411 is straightened; and once the pressing wheel 911 enters the linear groove 917, the second movable plate 99 can drive the pressurized connection block 924, so that the heating plate push block 925 moves on the guide connecting rod 929, and the heating block 918 gradually approaches the hot pressing plate 919 until they fit together, thereby completing the sealing. Among them, the setting of the compression spring 926 can enable the heating block 918 and the hot pressing plate 919 to be quickly reset and separated. It can be seen that in this embodiment, the straightening and sealing actions are performed continuously, thereby greatly shortening the operation time, thereby further improving the sealing efficiency.

[0135] In the above embodiment, the installation method of the compression spring 926 can also be selected in a wide range, and can be set independently of the guide connecting rod 929, but in order to further improve the rebound stability of the compression spring 926, preferably, the compression spring 926 is sleeved on the guide connecting rod 929. Thus, the guide connecting rod 929 can guide the compression spring 926, and at the same time, it can also avoid excessive deformation of the compression spring 926, thereby extending the service life of the compression spring 926.

[0136] On the basis of the above embodiment, in order to further improve the straightening effect, preferably, the front end of the bottom of the hot pressing plate 919 is provided with a first guide plate 920, and the front end of the bottom of the heating block 918 is provided with a second guide plate 921, and a gap is formed between the first guide plate 920 and the second guide plate 921. The gap between the hot pressing plate 919 and the heating block 918 can complete the straightening operation of the packaging bag 411, but in order to further improve the straightening effect, the first guide plate 920 and the second guide plate 921 can further play a role in guiding and straightening.

[0137] On this basis, the specific structures of the first guide plate 920 and the second guide plate 921 can be selected in a wide range, but in order to improve the efficiency of the packaging bag 411 entering between the first guide plate 920 and the second guide plate 921, preferably, the front ends of the first guide plate 920 and the second guide plate 921 are in an outward eight-shaped shape. The outward eight-shaped bell-mouth shape can help the packaging bag 411 enter between the first guide plate 920 and the second guide plate 921 to complete the straightening action to the greatest extent, thereby improving the accuracy of straightening.

[0138] In this embodiment, the specific structure of the driving unit 93 can be selected in a wide range. In order to further facilitate operation, preferably, the driving unit 93 is a motor.

[0139] In the present invention, in order to facilitate the separation between the fixed frame 415 and the movable frame 412, the movable frame 412 is connected to a bag dropping mechanism 96, wherein the specific structure of the bag dropping mechanism 96 can have various forms, but for the convenience of operation, preferably, the bag dropping mechanism 96 includes a middle electromagnet assembly 930 and two side electromagnet assemblies 913; the two side electromagnet assemblies 913 are located on both sides of the middle electromagnet assembly 930, and the middle electromagnet assembly 930 is connected to the driving rod 416; the middle electromagnet assembly 930 and the two side electromagnet assemblies 913 can both move forward and backward relative to the fixed frame 415; when the movable frame 412 is away from the fixed frame 415, the middle electromagnet assembly 930 can press the clamping member 413 to make the packaging bag 411 detach from the guide groove 414.

[0140] Therefore, as long as the middle electromagnet assembly 930 is started, the driving rod 416 can be driven to move forward and backward, thereby driving the movable frame 412 away from the fixed frame 415, or closing the movable frame 415 and the fixed frame 412; once the top seal of the packaging bag 411 is completed, the packaging bag 411 needs to be removed from the packaging bag fixing mechanism 41. At this time, the side electromagnet assembly 913 can be started, and the side electromagnet assembly 913 can move forward to press the clamping member 413. At this time, the side seal of the packaging bag 411 can be released from the guide groove 414, and under the action of gravity, the packaging bag 411 can automatically fall to complete the bag taking action.

[0141] Finally, in the present invention, there is no specific limitation on what kind of article the granular product is, but considering the scope of application of the system, preferably, the granular product is a granular pharmaceutical preparation.

[0142] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
