Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical packaging equipment, in particular to a granule pharmaceutical sealing and packaging machine. Background Art

[0002] A packaging machine is a type of machine that packages materials into finished products and can be used in fields such as food and chemicals to protect and divide the materials. A granule packaging machine is suitable for the quantitative packaging of granular materials. It realizes packaging by expanding the packaging bag, inflating it with air, then injecting materials, and finally sealing the bag.

[0003] In the existing packaging machine, during the material injection process, granular pharmaceuticals are likely to adhere to the inner wall of the material injection device and are not easily dropped, resulting in the accumulation of scattered granular pharmaceuticals in the material injection device. The accumulated granules remain in the material injection device for a long time, and the remaining granules are prone to deterioration, leading to waste of raw materials. There is also a risk of carrying deteriorated granules during subsequent material feeding, and the firmly adsorbed granules will also affect the smoothness of subsequent granule falling and the efficiency of material injection. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the problems in the related art to some extent. For this reason, one of the purposes of the utility model is to provide a granule pharmaceutical sealing and packaging machine, which is used to synchronously blow off the granules adsorbed on the inner wall during the material discharging process of the material injection device, avoiding the remaining of granules on the inner wall, maintaining the cleanliness inside the material injection device, improving the smoothness of granule discharging, and improving the efficiency of material injection.

[0005] A granule pharmaceutical sealing and packaging machine, the granule pharmaceutical sealing and packaging machine includes:

[0006] A transmission mechanism, the transmission mechanism is provided with a plurality of workstations, and the transmission mechanism moves linearly in the horizontal direction;

[0007] A blowing mechanism, the blowing mechanism is arranged above the transmission mechanism, the blowing mechanism includes a first driving member, a blower and a blowing member, the first driving member is drivingly connected to the blowing member to drive the blowing member to rotate, and the blower is connected to the blowing member;

[0008] A material injection device, the material injection device is arranged above the transmission mechanism and on one side of the blowing member, the material injection device is provided with a feed inlet at the top, a discharge outlet at the bottom, and an air inlet on a side surface close to the blowing member, and the discharge outlet is located above the workstation;

[0009] When the blowing member faces the workstation, it is in an open-bag state, and when it faces the air inlet, it is in an auxiliary material-discharging state.

[0010] Further, a wind guiding channel is also provided inside the material injection device. The wind guiding channel extends in an arc shape towards the direction of the feed inlet. One end of the wind guiding channel communicates with the air inlet, and the other end is arranged towards the inner wall on the side close to the air inlet.

[0011] The setting of the wind guiding channel can, on the one hand, make the incoming air flow along the inner wall of the material injection device, avoiding the incoming air flowing towards the middle and affecting the feeding of particles; on the other hand, it can prevent particles from falling out from the air inlet, realizing the normal discharging of particles.

[0012] Further, the diameter of the wind guiding channel gradually decreases from one end of the air inlet to the other end.

[0013] Utilizing the Venturi effect, the air flow is accelerated by narrowing and expanding the pipe diameter and surrounding air is sucked in through negative pressure, thereby increasing the volume and energy of the air flow and improving efficiency.

[0014] Further, a wind guiding groove is recessed on the side wall of the material injection device close to the air inlet. One opening edge of the wind guiding groove is arranged close to the other end of the wind guiding channel, and the opposite opening edge is arranged towards the inner wall on the other side of the material injection device.

[0015] The setting of the wind guiding groove can guide the outgoing air of the wind guiding channel to the other side wall of the material injection device, reducing the air flowing out from the air inlet, realizing the effect of the air flowing from one side to the other side and the internal circulating flow of the material injection device. The air can flow along the other side wall towards the discharge port, which can not only blow the particles to the discharge port, but also has the effect of accelerating the falling of the particles fed into the material injection device.

[0016] Further, the wind guiding grooves are provided on both side walls of the material injection device.

[0017] The wind guiding groove on the other side wall can guide the outgoing air of the opposite wind guiding groove to the direction of the discharge port of the material injection device, realizing the effect of guiding the air to flow from the feed inlet to the discharge port and the internal circulating flow of the material injection device.

[0018] Further, the side wall of the material injection device opposite to the air inlet is inclined inward along the direction from the feed inlet to the discharge port.

[0019] The inclined side wall ensures that the material can flow more smoothly towards the discharge port, reducing the residence time of the material in the hopper, thereby avoiding the blockage or deterioration that may be caused by the material staying in the hopper for a long time.

[0020] Further, the material injection device is further provided with a sewage discharge assembly. The sewage discharge assembly includes a rotating shaft, a baffle plate, and a diversion member. A sewage discharge port is formed on a side wall of the material injection device opposite to the air inlet. The rotating shaft is rotatably connected to the edge of the sewage discharge port. The baffle plate and the diversion member are fixedly connected to the rotating shaft at intervals. The inlet of the diversion member penetrates through the rotating shaft, and the rotating shaft is rotated to drive the baffle plate and the diversion member to rotate.

[0021] When it is necessary to clean the material injection device, the sewage discharge assembly can be utilized. The design of the sewage discharge assembly not only ensures the cleanliness of the material injection device but also improves the working efficiency.

[0022] Further, the granule medicine sealing and packaging machine further includes a frame. The transmission mechanism and the blowing mechanism are both arranged on the frame. The material injection device is detachably connected to the frame.

[0023] The detachable connection between the material injection device and the frame enables detachable use. The material injection device can be disassembled, replaced, and repaired, improving the flexibility of use of the material injection device.

[0024] Further, a clamping groove is formed at the top of the frame. A clamping buckle protrudes from the outer surface of the material injection device. The clamping buckle is slidably clamped and matched with the clamping groove.

[0025] The clamping and matching between the material injection device and the frame are fast and convenient for installation and disassembly, and the connection is firm. Such a design not only greatly improves the working efficiency but also reduces the labor intensity of the operator.

[0026] Further, a fastening groove is formed on a side wall of the frame adjacent to the clamping groove. The fastening groove communicates with the clamping groove. The granule medicine sealing and packaging machine is further provided with a limiting member. The limiting member penetrates through the fastening groove and abuts against the clamping buckle.

[0027] After the material injection device is completely clamped to the frame, the limiting member is clamped into the fastening groove to ensure that the material injection device will not fall off due to external force or vibration during the working process. This not only ensures the normal operation of the production line but also ensures the safety of the operator.

[0028] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art:

[0029] The present device is provided with a blowing mechanism and a material injection device. The blowing member of the blowing mechanism can be driven to rotate by a first driving member to change the blowing direction of the blowing member. An air inlet is provided on the side wall of the material injection device. The blowing member can change its direction to face the working station or the air inlet. For the pharmaceutical packaging, the blowing and bag-opening process is carried out first, and then the material injection process. When in the bag-opening process, the blowing member blows towards the working station to blow open the packaging bag. After the bag is opened, the blowing member turns to face the air inlet and blows into the interior of the material injection device. The air flows along the inner wall of the material injection device, which can blow off the particles on the inner wall. Moreover, the air circulates inside the material injection device, which can accelerate the falling speed of the particles and improve the material injection efficiency.

[0030] On the other hand, without adding additional mechanisms, the effect of blowing off the particles inside the material injection device can be achieved, saving the production cost, improving the production efficiency, and effectively utilizing the standby period of the blowing member during the material injection process, improving the production adaptability and utilization rate of the mechanism, and enhancing the production effect.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. Embodiment 1

[0044] As Figure 1 、 Figure 2 shown, a sealed packaging machine 1 for granular medicines provided by the present application includes:

[0045] A transmission mechanism 10, the transmission mechanism 10 is provided with three working stations 11, and the transmission mechanism 10 moves linearly in the horizontal direction;

[0046] A blowing mechanism 30, the blowing mechanism 30 is arranged above the transmission mechanism 10, the blowing mechanism 30 includes a first driving member 31, a blower 32 and a blowing member 33, the first driving member 31 is drivingly connected to the blowing member 33 to drive the blowing member 33 to rotate, and the blower 32 is connected to the blowing member 33;

[0047] An injection device 50, the injection device 50 is arranged above the transmission mechanism 10 and on one side of the blowing member 33, the injection device 50 is provided with a feed inlet 51 at the top, a discharge outlet 52 at the bottom and an air inlet 53 on the side surface close to the blowing member 33, and the discharge outlet 52 is located above the working station 11;

[0048] When the blowing member 33 faces the working station 11, it is in the bag-opening state, and when it faces the air inlet 53, it is in the state of assisting in material feeding.

[0049] The conveying mechanism 10 is provided with a plurality of working stations 11, and the number of working stations can be 3, 4, 5, etc. In this embodiment, the number of working stations 11 provided by the conveying mechanism 10 is 3. The three working stations 11 can respectively correspond to three processes of packaging bag collection, packaging bag opening and bagging, and packaging bag sealing. The three working stations 11 operate synchronously. After a single process is completed, it moves to the next process, and the state where the three working stations work simultaneously in sequence can be realized, and the uninterrupted operation of the three processes corresponding to the three working stations 11 can be maintained.

[0050] In this embodiment, the first driving member 31 is selected as a rotating cylinder. The rotating cylinder converts the energy of compressed air into rotational or oscillating motion, and has the advantages of saving space, precise rotation control, and high torque output, and can effectively save the occupied space. The first driving member 31 is connected to the side surface of the blowing member 33, and the blower 32 is connected to the inlet end of the blowing member 33 to provide high-speed air for the blowing member 33. The other end of the blowing member 33 is the air outlet end. The first driving member 31 is connected to the blowing member 33 and can drive the blowing member 33 to rotate to change the orientation of the air outlet. When rotating downward, the air outlet faces the working station 11, and there is a packaging bag to be opened in the working station 11. When the packaging bag is opened, the blowing member 33 blows air at the opening of the packaging bag, and the packaging bag can be blown open until it is in an open state, realizing the effect of opening the packaging bag; when the packaging bag is opened, the blowing member 33 can stop blowing air at the packaging bag, and then the feeding process for the packaging bag is required. The feeding device 50 located above the working station 11 starts to feed materials. The blowing member 33 rotates upward so that the air outlet faces the air inlet 53 of the feeding device 50, realizing blowing air into the feeding device 50. The air flows along the inside of the feeding device 50, and the particles adsorbed on the inner wall of the feeding device 50 can be blown off and can circulate inside the feeding device 50. When the air circulates in the direction from the feeding port 51 to the discharging port 52, it is in the same direction as the feeding direction of the particles, and thus the falling speed of the particles can be increased, realizing the effect of improving the feeding efficiency. It can be understood that the feeding device 50 can be a feeding hopper, a feeding box, a feeding cup, etc., and is not limited herein.

[0051] Optionally, a vibration device can be added at the discharging port 52 of the feeding device 50. The vibration device is connected to the feeding device 50 and can periodically generate minute vibrations. These vibrations can help the granular medicine near the discharging port 52 fall better into the packaging bag, reduce the blockage and retention of the medicine, and further improve the feeding efficiency.

[0052] Optionally, a detection device is provided at each station 11 of the transmission mechanism 10. This detection device can detect the position and status of the packaging bag in real time, such as whether it is placed correctly, whether it is open, etc. Once an abnormality in the position or status of the packaging bag is detected, the detection device will immediately send a signal to the control system, and the control system will pause the movement of the transmission mechanism 10 and activate the corresponding alarm device so that the operator can discover and handle the problem in time.

[0053] Optionally, an adjustment device can be added to the blowing mechanism 30. This adjustment device can adjust the rotation speed and blowing force of the blowing member 33 according to actual needs. For example, during the bag-opening stage of the packaging bag, the rotation speed and blowing force can be increased to ensure that the packaging bag can be opened quickly and completely; while during the auxiliary feeding stage, the rotation speed and blowing force can be appropriately reduced to avoid excessive disturbance to the granular medicine in the feeding device 50.

[0054] Optionally, protective covers and dust-proof devices can also be provided at key parts of the entire packaging machine. These devices can effectively prevent dust and sundries from entering the interior of the machine, ensuring the normal operation of the machine and the hygienic safety of the medicine. At the same time, the protective cover can also protect the safety of the operator and prevent accidents during the operation of the machine. Embodiment 2

[0055] As Figure 1 - Figure 3 shown, a granular medicine sealing and packaging machine 1 provided by the present application includes:

[0056] A transmission mechanism 10, the transmission mechanism 10 is provided with six stations 11, and the transmission mechanism 10 moves linearly in the horizontal direction;

[0057] A blowing mechanism 30, the blowing mechanism 30 is arranged above the transmission mechanism 10, the blowing mechanism 30 includes a first driving member 31, a blower 32 and a blowing member 33, the first driving member 31 is drivingly connected to the blowing member 33 to drive the blowing member 33 to rotate, and the blower 32 is connected to the blowing member 33;

[0058] A feeding device 50, the feeding device 50 is arranged above the transmission mechanism 10 and on one side of the blowing member 33, the feeding device 50 is provided with a feeding port 51 at the top, a discharging port 52 at the bottom and an air inlet 53 on a side surface close to the blowing member 33, and the discharging port 52 is located above the station 11;

[0059] When the blowing member 33 is arranged facing the station 11, it is in the bag-opening state, and when it is arranged facing the air inlet 53, it is in the auxiliary feeding state.

[0060] In this embodiment, the conveying mechanism 10 is provided with 6 workstations 11. The conveying mechanism 10 is also provided with a circulating conveyor belt. The 6 workstations 11 respectively correspond to the upper and lower 3 workstations 11 of the circulating conveyor belt. The 3 workstations 11 located above can respectively correspond to the three processes of packaging bag collection, packaging bag opening and loading, and packaging bag sealing. The three workstations 11 operate synchronously. After a single process is completed, it moves to the next process, and the state where the three workstations work simultaneously in sequence can be achieved. After the packaging bag sealing and blanking processes are completed, the last workstation 11 moves downward, and the next workstation 11 below moves upward to enter the packaging bag collection process, that is, the upper and lower workstations 11 are replaced to achieve the overall circulating effect and maintain the uninterrupted operation of the three processes corresponding to the six workstations 11.

[0061] In this embodiment, the first driving member 31 is selected as a servo motor. The servo motor has the characteristics of high precision, fast response, high torque density, and intelligent control, and can accurately control the rotation angle of the blowing member 33.

[0062] Furthermore, a wind guiding channel 54 is also provided inside the feeding device 50. The wind guiding channel 54 extends in an arc shape towards the direction of the feeding port 51. One end of the wind guiding channel 54 communicates with the air inlet 53, and the other end is arranged towards the inner wall on the side close to the air inlet 53.

[0063] The starting point of the wind guiding channel 54 is connected to the air inlet 53 to ensure that the air flow can smoothly enter; while its end point points to the inner wall on the side close to the air inlet 53. Such a layout not only optimizes the trajectory of air circulation but also improves the efficiency of the wind guiding channel 54. The setting of the wind guiding channel 54, on the one hand, can make the incoming air flow along the inner wall of the feeding device 50, avoiding the incoming air flowing towards the middle and affecting the feeding of the particles; on the other hand, it can prevent the particles from falling out from the air inlet 53, realizing the normal discharging of the particles.

[0064] Optionally, anti-slip patterns are carefully designed on both sides of the wind guiding channel 54. These patterns can increase the friction between the particles and the inner wall of the feeding device 50, thereby preventing the particles from sliding or blocking during the flowing process. At the same time, the design of the anti-slip patterns can also effectively reduce the wear between the particles and the inner wall, and extend the service life of the feeding device 50.

[0065] Optionally, a vibrator is also provided at the bottom of the feeding device 50. When the particles encounter resistance during the flowing process, the vibrator will generate slight vibrations to help the particles flow out smoothly. This design not only improves the fluidity of the particles but also reduces the production interruption caused by particle blockage and improves the production efficiency.

[0066] Optionally, we also note that during the air intake process, the humidity of the particles may change due to temperature variations, thereby affecting their fluidity. Therefore, at the position of the air inlet 53, we have specifically installed a temperature regulation device. By adjusting the temperature of the incoming air, we can ensure that the particles maintain a stable humidity during the flow process, thus maintaining their good fluidity.

[0067] Furthermore, the diameter of the air guiding channel 54 gradually decreases from one end of the air inlet 53 to the other end. Utilizing the Venturi effect, the air flow is accelerated by reducing and expanding the pipe diameter, and surrounding air is suctioned through negative pressure, thereby increasing the volume and energy of the air flow and improving efficiency. Through the constricted diameter setting, a high-velocity air flow is achieved at the outlet of the air guiding channel 54, increasing the wind force. The wind flows inside the feeding device 50, and can blow off the particles adsorbed on the inner wall of the feeding device 50.

[0068] Furthermore, a wind guiding groove 55 is recessed on one side wall of the feeding device 50 close to the air inlet 53. One side opening edge of the wind guiding groove 55 is arranged close to the other end of the air guiding channel 54, and the opposite side opening edge faces the inner wall of the other side of the feeding device 50. The setting of the wind guiding groove 55 can guide the air flow from the air guiding channel 54 to the other side wall of the feeding device 50, reducing the air flow out of the air inlet 53, achieving the effect of air flowing from one side to the other side, and realizing the internal circulating flow effect of the feeding device 50. The wind can flow along the other side wall towards the discharge port 52, which can not only blow the particles to the discharge port 52, but also has the effect of accelerating the falling of the particles fed into the feeding device 50.

[0069] Furthermore, wind guiding grooves 55 are provided on both side walls of the feeding device 50. The wind guiding groove 55 on the other side wall can guide the air flow from the opposite wind guiding groove 55 towards the discharge port 52 of the feeding device 50, achieving the effect of guiding the air flow to flow from the feeding port 51 to the discharge port 52, and realizing the internal circulating flow effect of the feeding device 50.

[0070] Optionally, to meet the requirements in different working environments, we have further optimized the design of the feeding device 50. First, adjustable wind direction devices are configured on both wind guiding grooves 55, which means that users can flexibly adjust the wind direction and wind speed according to actual needs. This not only enhances the flexibility of the device but also improves work efficiency.

[0071] Optionally, rotary wind blades can be added at the bottom of the wind guiding groove 55. When the wind force passes through the wind guiding groove 55, the wind blades will rotate accordingly, generating additional power to push the particles to flow towards the discharge port 52 faster. This design not only improves the feeding speed but also effectively avoids the retention or blockage of particles in the feeding device 50.

[0072] Optionally, to ensure the stability of the device during long-term operation, we also upgraded the material of the feeding device 50. High-strength and wear-resistant alloy materials, such as stainless steel and aluminum alloy, were used, enabling the feeding device 50 to maintain its shape and performance even when subjected to a large number of particle impacts. At the same time, this material also has excellent anti-corrosion properties and can be used for a long time without damage in a humid and highly corrosive environment. Alternatively, polytetrafluoroethylene, high-density polyethylene, polycarbonate, etc. can also be used. The surface of the feeding device 50 made of this type of material is extremely smooth, hardly adsorbing any substances, very easy to clean, and reducing particle adhesion; or an epoxy resin coating is provided on the inner wall of the feeding device 50 to form a smooth, durable, and easy-to-clean protective layer, which can also achieve the effect of easy cleaning.

[0073] Furthermore, one side wall of the feeding device 50 opposite to the air inlet 53 is inclined inward along the direction from the feed inlet 51 to the discharge outlet 52. This inclined design not only optimizes the flow path of the material in the feeding device 50 but also invisibly improves the efficiency of the entire working process. The inclined side wall ensures that the material can flow more smoothly towards the discharge outlet 52, reducing the residence time of the material in the hopper and thus avoiding blockage or deterioration that may occur due to the long-term stay of the material in the hopper. Moreover, the inclined side wall design also takes into account the situation where the material may scatter due to the impact force when entering the feeding device 50. By inclining inward, the material can quickly find a stable flow direction after entering the hopper, reducing the collision and accumulation of the material in the hopper and further ensuring the smoothness of the material flow. It is worth mentioning that this inclined design also brings additional energy-saving effects. Since the material can flow more quickly towards the discharge outlet 52, the conversion between full load and no load of the feeding device 50 is more rapid, reducing the ineffective operation time of the motor in the no-load state and thus reducing the energy consumption of the entire device. Embodiment 3

[0074] As Figure 1 - Figure 5 shown, a granule medicine sealing and packaging machine 1 provided by the present application includes:

[0075] A transmission mechanism 10, the transmission mechanism 10 is provided with eight stations 11, and the transmission mechanism 10 moves linearly in the horizontal direction;

[0076] A blowing mechanism 30, the blowing mechanism 30 is arranged above the transmission mechanism 10, the blowing mechanism 30 includes a first driving member 31, a blower 32 and a blowing member 33, the first driving member 31 is drivingly connected to the blowing member 33 to drive the blowing member 33 to rotate, and the blower 32 is connected to the blowing member 33;

[0077] The material injection device 50 is arranged above the transmission mechanism 10 and on one side of the blowing member 33. The material injection device 50 is provided with a feed inlet 51 at the top, a discharge outlet 52 at the bottom, and an air inlet 53 on a side surface close to the blowing member 33. The discharge outlet 52 is located above the working station 11.

[0078] When the blowing member 33 faces the working station 11, it is in the bag-opening state, and when it faces the air inlet 53, it is in the state of assisting in material discharging.

[0079] In this embodiment, the number of the working stations 11 arranged on the transmission mechanism 10 is 8. The 3 working stations 11 located above can respectively correspond to four processes of packaging bag collection, packaging bag opening and bagging, packaging bag sealing, and packaging bag discharging. By adding a discharging process and having the four working stations 11 operate synchronously, after a single process is completed, it moves to the next process, and a state where the four working stations work simultaneously in sequence can be achieved, maintaining the uninterrupted operation of the four processes corresponding to the four working stations 11.

[0080] In this embodiment, the first driving member 31 is selected as a planetary gear. The planetary gear has the characteristics of high efficiency, large transmission ratio, low noise, and small occupied space, which can reduce the overall volume of the blowing mechanism 30 of the packaging machine and improve the overall portability.

[0081] Furthermore, the material injection device 50 is further provided with a sewage discharge assembly 56. The sewage discharge assembly 56 includes a rotating shaft 561, a baffle 562, and a flow guide member 563. A sewage discharge port is formed on a side wall of the material injection device 50 opposite to the air inlet 53. The rotating shaft 561 is rotatably connected to the edge of the sewage discharge port. The baffle 562 and the flow guide member 563 are fixedly connected to the rotating shaft 561 at intervals. The inlet of the flow guide member 563 penetrates through the rotating shaft 561, and the rotating shaft 561 is rotated to drive the baffle 562 and the flow guide member 563 to rotate.

[0082] By rotating the rotating shaft 561, the baffle 562 can be set in different directions. One direction is to rotate downward, that is, to block the sewage outlet. The interior of the feeding device 50 is communicated with the discharge port 52 to achieve normal discharging. The other direction is to rotate upward, that is, to block the interior of the feeding device 50 and open the sewage outlet. The materials in the feeding device 50 are blocked by the baffle 562 after falling and guided to the sewage outlet. When it is necessary to clean the feeding device 50, the sewage discharge assembly 56 can be utilized. The design of the sewage discharge assembly 56 not only ensures the cleaning of the feeding device 50 but also improves the working efficiency. When too many impurities or wastes accumulate in the feeding device 50, the operator only needs to gently rotate the rotating shaft 561, and the baffle 562 and the guiding member 563 will rotate accordingly. The baffle 562 can block the discharge port 52, and the baffle 562 is communicated with the sewage outlet through the guiding member 563, so that the impurities or wastes can smoothly pass through the guiding member 563 and be discharged from the sewage outlet. At the same time, the inlet of the guiding member 563 penetrates through the rotating shaft 561. Such a design enables the guiding member 563 to more effectively guide the wastes or impurities to be discharged along the established path during the rotation process, avoiding secondary pollution to the interior of the feeding device 50. Optionally, a sealing member, such as a sealing ring, a gasket, etc., can also be provided at the end of the baffle 562 to fit the end of the baffle 562 with the inner wall of the feeding device 50, reduce the gap, and keep the materials flowing out from the sewage outlet.

[0083] Optionally, in order to further improve the sewage discharge efficiency, the sewage discharge assembly 56 of the feeding device 50 is also equipped with an automatic control system. When the wastes or impurities in the feeding device 50 accumulate to a certain extent, the automatic control system will send a signal to drive the motor to automatically rotate the rotating shaft 561, thus realizing the automation of sewage discharge. This not only reduces the labor intensity of the operator but also improves the working efficiency and safety.

[0084] Regarding the material selection of the sewage discharge assembly 56, we have adopted corrosion-resistant and high-temperature-resistant alloy materials, such as stainless steel, aluminum alloy, etc., to ensure that the sewage discharge assembly 56 can maintain stable performance and a long service life under a long-term and high-load working environment. At the same time, we have also optimized the structure design of the sewage discharge assembly 56 to enable it to remain stable during the sewage discharge process and avoid damage caused by vibration or impact.

[0085] Furthermore, the granular medicine sealing and packaging machine further includes a frame 60. The transmission mechanism 10 and the blowing mechanism 30 are both arranged on the frame 60, and the feeding device 50 is detachably connected to the frame 60. The detachable connection method can be pin connection, fitting connection, plug-in connection, clamping connection, etc. Through the detachable connection, the detachable setting of the feeding device 50 is realized, and the feeding device 50 can be disassembled, replaced, and repaired, improving the flexibility of use of the feeding device 50.

[0086] Further, a clamping groove 61 is formed at the top of the frame 60, and a clamping buckle 57 is protruded on the outer surface of the feeding device 50. The clamping buckle 57 is slidably clamped with the clamping groove 61.

[0087] Under the careful design of the frame 60, the formation of the clamping groove 61 is not only for the simple sliding clamping with the clamping buckle 57 of the feeding device 50, but also for improving the stability and working efficiency of the whole device. The inside of the clamping groove 61 is made of wear-resistant and highly lubricating material, ensuring that the friction between the clamping buckle 57 and the clamping groove 61 will not be too large during long-term and high-frequency use, thus guaranteeing the stability and durability of the device. At the same time, the design of the clamping buckle 57 also fully considers the convenience and safety of operation. When loading the feeding device 50, the operator only needs to gently align the clamping buckle 57 with the clamping groove 61 and then gently push it to complete the clamping of the two. When it is necessary to clean or replace the feeding device 50, it only needs to be gently pulled to easily separate. Such a design not only greatly improves the working efficiency, but also reduces the labor intensity of the operator.

[0088] Further, a fastening groove 63 is formed on a side wall adjacent to the clamping groove 61 of the frame 60. The fastening groove 63 communicates with the clamping groove 61. The granular medicine sealing and packaging machine is also provided with a limiting member 70. The limiting member 70 penetrates through the fastening groove 63 and abuts against the clamping buckle 57. A set of safety locking mechanism is also designed between the frame 60 and the clamping buckle 57. After the feeding device 50 is completely clamped with the frame 60, the limiting member 70 is clamped into the fastening groove 63 to ensure that the feeding device 50 will not fall off due to external force or vibration during the working process. This not only guarantees the normal operation of the production line, but also ensures the safety of the operator.
