[0002] At present, in the medicine bagging industry, it is necessary to first assemble the unformed bags into shape, then put the medicine into the bags, and then the opening of the bags needs to be heat-sealed. However, most of the traditional scale operations are manual, which has the problems of low work efficiency and high labor cost. In particular, when the medicine drop opening of the bag is wrinkled during the heat-sealing process, the sealed part of the medicine drop bag after heat sealing will be wrinkled. At this time, the medicine drop bag is prone to air leakage, and secondly, it is also easy to affect the aesthetics of the medicine drop bag. Summary of the Invention

[0003] The purpose of the present invention is to address the above problems in the existing technology and to propose a fully automatic medicine collecting device with a high degree of automation and capable of improving the airtightness of the medicine bag after heat sealing.

[0007] There are multiple retainers, each of which is located on a turntable. The turntable can drive each retainer to rotate. Each retainer can clamp at least two medicine dropping bags at the same time. When the bag forming device makes an unformed bag into a single medicine dropping bag with a medicine dropping opening on the top, the medicine dropping bag will pass through the retainer located directly above the bag forming device. Thereafter, the retainer clamps the medicine dropping bag and keeps the medicine dropping opening of the medicine dropping bag in an open state.

[0053] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0054] like Figure 1 、 Figure 16 、 Figure 18 and Figure 21 As shown, the fully automatic medicine collecting equipment of the present invention includes a frame 900, a bag forming device 940, a turntable 910, a lifting mechanism 100, a lifting plate 110, a tension mechanism 200, a retainer 500, a medicine bag 540, a hot pressing mechanism 400 and a clamping mechanism 300.

[0055] In the present invention, the unformed bag wound on the reel 610 is folded once and then wound on the reel 610. Therefore, the first side of the unformed bag is closed due to the folding, and the second side, bottom and top sides are all open.

[0056] The frame 900 is provided with a bag forming device 940, a turntable 910 and a lifting mechanism 100. The lifting mechanism 100 is movably provided with a lifting plate 110, and the lifting plate 110 can be raised and lowered relative to the lifting mechanism 100. The pulling mechanism 200 is provided on the lifting mechanism 100; there are multiple retainers 500, each of which is provided on the turntable 910, and the turntable 910 can drive each retainer 500 to rotate. Each retainer 500 can clamp at least two medicine bags 540 at the same time, and the hot pressing mechanism 400 is movably provided on the bottom surface of the lifting plate 110. A pair of clamping mechanisms 300 for clamping the ends of each medicine bag 540 are also provided on the bottom surface of the lifting plate 110, and one of the clamping mechanisms 300 can move relative to the lifting plate 110.

[0057] During operation, the bag forming device 940 guides, conveys, heat-seals and cuts the unformed bag to form a single medicine bag 540 with a medicine drop opening 541 on the top. During this process, the medicine bag 540 passes through the holder 500 located just above the bag forming device 940. Thereafter, the holder 500 clamps the medicine bag 540 and keeps the medicine drop opening 541 of the medicine bag 540 in an open state. Afterwards, the turntable 910 drives the holder 500 to rotate one station, so that the bag forming device 940 passes another medicine bag 540 through the holder 500. In this way, a holder 540 can be formed. 00 clamps two medicine bags 540 at the same time. After that, the turntable 910 drives the holder 500 to rotate. During the rotation, people can put the tablets into the medicine bags 540 through the medicine dropping openings 541 of the medicine bags 540. When the turntable 910 drives the holder 500 to rotate to the bottom of the lifting plate 110 and the holder 500 is buckled with the tension mechanism 200, the lifting mechanism 100 drives the lifting plate 110 to descend to the preset position, that is, when the clamping mechanism 300 is aligned with the two ends of the medicine dropping openings 541 of the medicine bags 540, the lifting plate 110 stops descending. After that, the two clamping mechanisms 300 clamp the two medicine bags respectively. The two ends of the bag 540 are then opened by the tensioning mechanism 200, and the holder 500 no longer clamps the medicine bag 540. Then, one of the clamping mechanisms 300 moves relative to the lifting plate 110 in a direction away from the other clamping mechanism 300, so that the medicine dropping openings 541 of the two medicine bags 540 can be leveled. After that, the hot pressing mechanism 400 performs hot pressing on the medicine dropping openings 541 of the medicine bags 540 to seal the medicine dropping openings 541 of the medicine bags 540. When the hot pressing is completed, the hot pressing mechanism 400 returns to its initial position, and the two clamping mechanisms 300 are released and returned to their initial state. The clamping mechanism 300 moved by the lowering plate 110 is also reset to the initial position, and in this process, the two medicine bags 540 automatically fall from the retainer 500. Through the above steps, the fully automatic production of the medicine bags 540, the delivery of tablets and the heat sealing of the medicine bags 540 can be completed at one time, and the wrinkles at the sealing parts of the medicine bags 540 during the heat sealing process are avoided, and the air leakage of the medicine bags 540 is avoided, and the aesthetics of the medicine bags 540 after heat sealing is effectively increased. Here, the full automation of people's production of the medicine bags 540, heat sealing of the medicine bags 540 and delivery of tablets is reflected, which effectively improves people's work efficiency.

[0058] like Figure 16 — Figure 20 As shown, further, a connecting seat 911 for connecting each retainer 500 is provided on the turntable 910. When the turntable 910 rotates, the turntable 910 will drive the connecting seat 911 to rotate, so that the retainer can be driven to rotate synchronously.

[0059] The inner frame 600 is mounted with a reel 610 for rolling up the unformed bag. The first side of the unformed bag is folded to form a closed opening, while the second side, bottom, and top sides are all open. In other words, the bag rolled up on the reel 610 is equivalent to a paper folded in half. To form a medicine bag 540 with a medicine drop opening 541, the second side and bottom sides must be sealed.

[0060] A heat sealing mechanism is provided on the inner frame 600 and forms a forming channel for the unformed bag to pass through. The unformed bag is transported from the reel 610 into the forming channel. The heat sealing mechanism sequentially heat-seals the second side edge and the bottom edge of the unformed bag and cuts the unformed bag into a single medicine dropping bag 540 having only a medicine dropping opening 541.

[0061] The medicine bag 540 is transported into the retainer 500 after passing through the forming channel. The retainer 500 clamps the medicine bag 540 and keeps the medicine opening 541 open at all times. At this time, the heat sealing mechanism heat seals and cuts the bottom edge of the medicine bag 540, and then the medicine can be put into the medicine bag 540.

[0062] This embodiment achieves the purpose of automatically preparing the medicine bag 540 through a heat-sealing mechanism, and then achieves the purpose of automatically opening the bag and dropping the medicine through the cooperation of the retainer 500 and the medicine storage container (not marked in the figure) set on the top of the frame 900. The entire working process is fully automatic and does not require manual operation, which greatly improves the efficiency of loading medicine and thus reduces the expenditure of labor costs.

[0063] The heat sealing mechanism includes a side sealing assembly 700, which includes a first heat sealing block 710 and a side sealing pad block 720 arranged on the left and right. The first heat sealing block 710 moves to abut against the side sealing pad block 720 and heat seals the second side of the unformed bag. The first heat sealing block 710 has a built-in thermocouple and plays a heating role. When the unformed bag enters the forming channel, its second side is located between the first heat sealing block 710 and the side sealing pad block 720. At this time, the first heat sealing block 710 moves to press the second side of the unformed bag onto the side sealing pad block 720, thereby achieving heat sealing of the second side of the unformed bag.

[0064] The heat sealing mechanism further includes a bottom heat sealing and cutting assembly 800, which includes: a movable plate 810 movably disposed on the inner frame 600; second heat sealing blocks 820 and a horizontal pressure pad 830 disposed on the left and right sides. As the movable plate 810 moves, the second heat sealing block 820 moves closer to or away from the horizontal pressure pad 830;

[0065] The serrated movable knife 840 and the flat-edged fixed knife 850 are arranged on the left and right, and the serrated movable knife 840 and the flat-edged fixed knife 850 are respectively arranged at the bottom of the second heat sealing block 820 and the horizontal pressure pad 830. When the second heat sealing block 820 contacts the horizontal pressure pad 830 and heat-seals the bottom edge of the medicine bag 540, the serrated movable knife 840 and the flat-edged fixed knife 850 cut the medicine bag 540 into shape.

[0066] When the bottom edge of the unformed bag is heat-sealed and cut, a complete medicine bag 540 is formed. At this time, the top of the medicine bag 540 has a medicine drop opening 541 to facilitate the dropping of medicines into the bag.

[0067] Preferably, the bottom heat sealing and cutting assembly 800 is located at the top of the side sealing assembly 700, and the channel between the first heat sealing block 710 and the side sealing pad block 720 and the channel between the second heat sealing block 820 and the horizontal pressure pad block 830 form a complete forming channel, wherein the forming channel is opened vertically to facilitate the heat sealing and cutting processes, and also to facilitate the formed medicine bag 540 to vertically enter the retainer 500 for clamping.

[0068] It is worth mentioning here that in this embodiment, the molding process of the medicine bag 540 is preferably set to first heat seal its second side edge, and then heat seal and cut its bottom edge, but it can also be changed to first heat seal its bottom edge, and then heat seal its second side edge and cut its bottom edge. This molding method is easy to think of for technical personnel in this field, and therefore should also fall within the scope of protection of this application.

[0069] Furthermore, the movable plate 810 is also provided with: a bearing mounting plate 860 connected to the movable plate 810; a linear bearing 870 is arranged on the bearing mounting plate 860; both ends of the pressure block guide column 880 are respectively connected to the linear bearing 870 and the second heat sealing block 820, and a fourth spring 890 is provided on the pressure block guide column 880.

[0070] Specifically, in this embodiment, the heat-sealing surface of the second heat-sealing block 820 exceeds the cutting surface of the serrated movable knife 840. During the process of the movable plate 810 moving toward the transverse pressing pad 830, the second heat-sealing block 820 first contacts the transverse pressing pad 830 and heat-seals the bottom of the heat-sealed bag. Then, the movable plate 810 continues to move in the same direction to compress the fourth spring 890. At this time, the second heat-sealing block 820 still presses the bottom edge of the unformed bag against the transverse pressing pad 830, while the serrated movable knife 840 continues to move in the same direction until the heat-sealed bag is cut.

[0071] That is to say, in this embodiment, after the second side of the unformed bag body is heat-sealed, the bottom edge heat-sealing and cutting process needs to be performed. In this process, the second heat-sealing block 820 first heat-seals the bottom edge of the unformed bag body, and then the serrated knife 840 will cut the heat-sealed bottom edge slightly downward.

[0072] In addition, the provision of the serrated movable knife 840 and the flat-edged fixed knife 850 can make the incision more neat, thereby ensuring the quality of the formed medicine bag 540.

[0073] Preferably, a guide mechanism is further provided in the molding channel, and the guide mechanism includes:

[0074] The inner guide plate 620 is vertically arranged on the forming channel, and the medicine bag 540 is sleeved on the inner guide plate 620 to ensure that its conveying track does not deviate from the forming channel;

[0075] The first pressing plate 630 is located at the side sealing assembly 700 and is used to press the medicine bag 540 there against the inner guide plate 620, thereby ensuring that the folded surface of the unformed bag does not deviate and the second side edges thereof are always aligned, thereby ensuring that wrinkles are not formed on the second side edges after heat sealing, thereby ensuring heat sealing quality;

[0076] The guide block 640 is arranged at the upper end of the inner guide plate 620. The bottom edge of the guide block 640 forms a guide slope 650 and is used to open the medicine drop opening 541 of the medicine drop bag 540, so that the medicine drop opening 541 of the medicine drop bag 540 can be automatically opened after the medicine drop bag 540 enters the retainer 500.

[0077] Preferably, the guiding mechanism also includes a pair of rubber-coated rollers 660, which are arranged between the side sealing assembly 700 and the bottom heat-sealing cutting assembly 800 and are located on the side of the inner guide plate 620, wherein the second side edge of the medicine bag 540 passes through between the pair of rubber-coated rollers 660 and is pressed. It is worth mentioning here that the setting of the rubber-coated rollers 660 not only plays a guiding role, but also prevents the folded surface of the unformed bag from slipping, thereby ensuring the heat-sealing quality of the medicine bag 540.

[0078] Preferably, the retainer 500 has a clamping opening 530 for the medicine bag 540 to enter, and the opening size of the clamping opening 530 decreases from bottom to top, and the medicine bag 540 enters from the bottom of the retainer 500. When it just enters, the clamping opening 530 guides the two side edges of the medicine bag 540. When the medicine bag 540 enters the top of the retainer 500, the clamping opening 530 can automatically clamp the medicine bag 540 and keep the bag opening of the medicine bag 540 in an open state at all times.

[0079] Further preferably, the retainer 500 also has a clamping jaw 522, which is rotatably arranged on the side of the retainer 500, and the clamping jaw 522 is provided with a contact plate 5221 and a soft block 5222. The contact plate 5221 is located outside the retainer 500, and the soft block 5222 is located in the clamping opening 530 on one side of the retainer 500.

[0080] Specifically, a control push rod 930 is movably provided in the frame 900. The control push rod 930 is pushed outward and pushes the contact plate 5221 so that the soft block 5222 rotates and moves out of the clamping port 530. At this time, the medicine bag 540 can smoothly enter the retainer 500. That is to say, before the medicine bag 540 enters the retainer 500, the control system will automatically operate the control push rod 930 to push forward and press the contact plate 5221, so that the soft block 5222 can be rotated out of the clamping port 530, so that the medicine bag 540 can smoothly enter the retainer 500. Then the control push rod 930 automatically retracts, and the clamping claw 522 automatically resets under the action of elastic potential energy. The soft block 5222 can clamp the side of the medicine bag 540 to ensure that it is always in a fixed position, which is convenient for the subsequent automatic medicine dropping work.

[0081] It is worth noting here that in order to ensure that the medicine bag 540 at the bottom of the medicine storage device is always in an open state when the medicine storage device automatically drops medicine, sensors 920 are also provided on the front and rear sides of the retainer 500. The sensor 920 is connected to the frame 900. When the medicine bag 540 is in an open state, the widest parts on both sides of the bag opening of the medicine bag 540 can block the infrared rays. At this time, the infrared receiver cannot receive the infrared signal. The system automatically determines that the medicine bag 540 is successfully opened, and then controls the medicine storage device to automatically drop medicine. Otherwise, the system generates an alarm and reminds nearby staff that the medicine bag 540 has not been successfully opened, thereby ensuring the smooth progress of the automatic medicine dropping and bagging work.

[0082] Preferably, in this embodiment, each time the turntable 910 rotates one station, the retainer 500 moves forward one station and moves to the bottom of the next medicine storage container for automatic medicine dropping. When the medicine is a Chinese medicinal material, the turntable 910 can be rotated so that each medicine storage container can drop the preset type of Chinese medicinal materials into the medicine dropping bag 540 in a quantitative manner. This not only improves the efficiency of the provision of Chinese medicinal materials, but also avoids the problem of inaccurate proportions caused by manual medicine picking.

[0083] like Figure 11 — Figure 15As shown, the hot pressing mechanism 400 includes a guide plate 410 movably mounted on the lifting plate 110 and the same number of hot pressing components 420 as the medicine bags. The guide plate 410 can move relative to the lifting plate 110, and the hot pressing components 420 can move relative to the lifting plate 110. The moving direction of the guide plate 410 is perpendicular to the moving direction of the hot pressing components 420. The guide plate 410 can drive the hot pressing components 420 to move. When the two clamping mechanisms 300 clamp the medicine bags and flatten the medicine dropping openings 541 of the medicine bags, it is necessary to drive the guide plate 410 to move relative to the lifting plate 110 so that the guide plate 410 can simultaneously drive the two hot pressing components 420 to close toward their respective centers until the hot pressing components 420 contact the medicine bags. The hot pressing components 420 can then perform hot pressing and sealing on the medicine dropping openings 541 of the medicine bags to complete the simultaneous sealing of the two medicine bags, thereby improving the efficiency of heat sealing.

[0084] Each of the hot pressing components 420 includes a left pressure piece 421 and a right pressure piece 422 that are slidably connected to the bottom surface of the lifting plate 110. The guide plate 410 is provided with a traction hole 411 that is slidably connected to the left pressure piece 421 and a right oblique hole 412 that is slidably connected to the right pressure piece 422. When the guide plate 410 moves relative to the lifting plate 110, the left pressure piece 421 will be affected by the path of the traction hole 411, so that the left pressure piece 421 moves accordingly relative to the lifting plate 110. At the same time, the right pressure piece 422 will also be affected by the path of the right inclined hole 412, so that the right pressure piece 422 can move accordingly relative to the lifting plate 110, that is, the right pressure piece 422 and the left pressure piece 421 are closed together, so that the medicine bag between the two can be hot pressed; when the hot pressing process is completed, the guide plate 410 moves in the opposite direction relative to the lifting plate 110, and the left pressure piece 421 and the right pressure piece 422 will also move in the opposite direction, thereby realizing that the hot pressing assembly 420 releases the medicine bag.

[0085] The left pressure piece 421 includes a left pressure plate 4211, and a left guide rod 4212 is provided on the left pressure plate 4211. The left guide rod 4212 passes through the lifting plate 110, and a left roller 4213 is provided at the end of the left guide rod 4212. The left roller 4213 is slidably inserted into the traction hole 411, and the traction hole 411 includes a left oblique hole 4111 and a vertical hole 4112. The extension line of the left oblique hole 4111 intersects with the extension line of the right oblique hole 412, and the left oblique hole 4111 and the right oblique hole 412 are in an eight-shaped shape, and the left oblique hole 4111 and the vertical hole 4112 are connected end to end. The right pressure piece 422 includes a right pressure seat 4221, and a hot pressing plate 4222 is provided on the side of the right pressure seat 4221 facing the left pressure piece 421. At least two hot pressing plates 4222 are movably provided on the hot pressing plate 4222. Pressure rod 4223, the ends of the two hot pressure rods 4223 are connected by a hot pressure block 4224, each of the hot pressure rods 4223 is provided with a hot pressure spring 4225, and the hot pressure spring 4225 is located between the hot pressure block 4224 and the hot pressure plate 4222, and the right pressure seat 4221 is provided with a right guide rod 4226, and the right guide rod 4226 passes through the lifting plate 110, and the end of the right guide rod 4226 is provided with a right roller 4227, and the right roller 4227 is slidably inserted into the right inclined hole 412; the bottom surface of the lifting plate 110 is provided with a fourth guide rail 111 that is slidably connected to the left pressure piece 421 and the right pressure piece 422, and the top surface of the lifting plate 110 is provided with a fifth guide rail 112 that is slidably connected to the guide plate 410, and the fourth guide rail 111 is perpendicular to the fifth guide rail 112.

[0086] When the guide plate 410 moves on the fifth guide rail 112 relative to the lifting plate 110, the left roller 4213 slides and is stuck in the traction hole 411, the right roller 4227 slides and is stuck in the right inclined hole 412, and the left pressure plate 4211 and the right pressure seat 4221 are both slidably connected to the fourth guide rail 111, so that the left roller 4213 slides from the left inclined hole 4111 to the vertical hole 4112 relative to the lifting plate 110, and the right roller 4227 slides from one end of the right inclined hole 412 away from the vertical hole 4112 to the other end relative to the lifting plate 110. At the same time, because the left roller 4213 is connected to the left pressure plate 4211 through the left guide rod 4212, and the right roller 4227 is connected to the right pressure seat 4221 through the right guide rod 4226, When the left roller 4213 moves in the left oblique hole 4111, the left pressure plate 4211 will move relative to the lifting plate 110 along the fourth guide rail 111 toward the right pressure seat 4221; when the left roller 4213 moves in the vertical hole 4112, the left pressure plate 4211 will remain stationary relative to the lifting plate 110; when the right roller 4227 moves in the right oblique hole 412, the right pressure seat 4221 will move relative to the lifting plate 110 along the fourth guide rail 111 toward the left pressure plate 4211 until the hot pressing block 4224 on the right pressure seat 4221 contacts the left pressure plate 4211. Since the hot pressing block 4224 is always in an electrically heated state, the medicine bag placed between the left pressure plate 4211 and the hot pressing block 4224 can be heat-sealed smoothly.

[0087] Furthermore, when the right pressure seat 4221 moves relative to the fourth guide rail 111, since the hot pressing block 4224 is installed on the hot pressing plate 4222 through the hot pressing rod 4223, the hot pressing plate 4222 and the right pressure seat 4221 are formed as one piece, so that the right pressure seat 4221 drives the hot pressing block 4224 to move synchronously, and when the hot pressing block 4224 and the left pressure plate 4211 clamp the medicine bag located therebetween, the hot pressing block 4224 moves relative to the hot pressing plate 4222, and the hot pressing rod 4223 shuttles inside the hot pressing plate 4222, so that the hot pressing spring 4225 is compressed and generates elastic force, thereby completing the hot pressing process of the medicine bag. Secondly, it can also have a buffering effect on the medicine bag, thereby better protecting the medicine bag, that is, avoiding the damage of the medicine bag during the hot pressing process of the left pressure piece 421 and the right pressure piece 422.

[0089] like Figure 9 — Figure 10 As shown, the lifting plate 110 is provided with a bag pulling assembly 114 for driving one of the clamping mechanisms 300 to move. The bag pulling assembly 114 is connected to the clamping mechanism 300, and the other clamping mechanism 300 is connected to the bottom surface of the lifting plate 110. Through the above structure, the two clamping mechanisms 300 can flatten the medicine dropping port 541 of the medicine bag.

[0090] Furthermore, each of the clamping mechanisms 300 includes a back plate 310, which can be connected to the lifting plate 110 or the bag pulling assembly 114. Specifically, the back plate 310 of the clamping mechanism 300 slidably connected to the lifting plate 110 is connected to the bag pulling assembly 114, and the other back plate 310 is detachably connected to the bottom surface of the lifting plate 110, so that the bag pulling assembly 114 can drive the clamping mechanism 300 connected thereto to move away from the other clamping mechanism 300, that is, the distance between the two clamping mechanisms 300 can be increased, thereby flattening the medicine dropping opening 541 of the medicine dropping bag located between the two clamping mechanisms 300;

[0091] A pair of movable plates 320 are slidingly provided on one side of the back plate 310, and each movable plate 320 is provided with two clamping rods 321, and each clamping rod 321 is located on the same plane. The clamping rods 321 on the two movable plates 320 are staggered. A second motor 330 is provided on the other side of the back plate 310, and the second motor 330 is provided with a second gear 331 that meshes with each movable plate 320. A third guide rail 311 is provided on the back plate 310 that is slidably connected to the movable plate 320.

[0092] The bag pulling assembly 114 includes a bag pulling motor 1141 provided on the lifting plate 110 and a clamping seat 1142 connected to one of the back plates 310.

The clamping seat 1142 is provided with a slide rail 115 that is slidably connected to the slide rail 115. Block 1145, when the bag pulling motor 1141 drives the screw rod 1143 to rotate, since the clamping seat 1142, the vertical plate 1144 and the back plate 310 are connected by threads, the screw rod 1143 threads through the vertical plate 1144, so that the screw rod 1143 can drive the vertical plate 1144 and the back plate 310 to move in a directional manner along the track of the slide rail 115, that is, the clamping mechanism 300 connected to the bag pulling assembly 114 can move relative to the lifting plate 110, that is, the distance between the two clamping mechanisms 300 can be changed.

[0093] like Figure 1 — Figure 6As shown, the pulling mechanism 200 includes: a fixed plate 210 connected to the lifting mechanism, a pulling component 220 is provided on the fixed plate 210, and an opening component 230 is provided on the pulling component 220. The opening component 230 can make the retainer 500 loosen the medicine bag. The fixed plate 210 is provided with a power member 240 for driving the pulling component 220 and the opening component 230 to move. When the power member 240 is running, the opening component 230 and the pulling component 220 can move relative to the fixed plate 210. That is, when the opening component 230 moves relative to the fixed plate 210 and the tension component 220 is stationary relative to the fixed plate 210, the opening component 230 can be pressed against the clamping part of the retainer 500 for clamping the dropped medicine bag. When the tension component 220 moves relative to the fixed plate 210 and the opening component 230 is stationary relative to the fixed plate 210, the retainer 500 can be pulled to open, and the clamping part releases the clamping of the dropped medicine bag, that is, the retainer 500 can release the dropped medicine bag.

[0094] The pulling assembly 220 includes a lower folding plate 221 provided on the fixed plate 210 and at least two pulling rods 222 that are movable through the lower folding plate 221. The two pulling rods 222 are connected by a pulling plate 223 at one end toward the retainer 500, and the other ends of the two pulling rods 222 are connected by a lower connecting plate 224. A lower driving plate 225 is slidingly provided on the lower folding plate 221 for driving the lower connecting plate 224 to move relative to the lower folding plate 221. When the power member 240 drives the lower driving plate 225 to move relative to the lower folding plate 221, the lower driving plate 225 will push the lower connecting plate 224 to move accordingly, so that the lower connecting plate 224 can drive the pulling rods 222 and the pulling plate 223 to move relative to the lower folding plate 221, and the pulling plate hooks the retainer 500, so that the pulling plate 223 can open the retainer 500.

[0095] The first spring 2221 is mounted on the pull rod 222, and the first spring 2221 is clamped between the pull plate 223 and the lower folding plate 221, wherein the movement direction of the lower driving plate 225 is perpendicular to the movement direction of the lower connecting plate 224. When the power part 240 drives the lower driving plate 225 to move relative to the lower folding plate 221, the lower roller 2241 will move back and forth on the second oblique edge 2251 and the second straight edge 2252. Specifically, when the lower roller 2241 is in close contact with the second oblique edge 2251, the second straight edge 2252 is engaged with the lower driving plate 225. When the second straight edge 2252 is closed, the lower connecting plate 224 is always stationary relative to the lower folding plate 221, so that the retainer 500 is in the closed state. At the same time, because the first spring 2221 is between the pulling plate 223 and the lower folding plate 221, a certain elastic force is also generated between the pulling plate 223 and the lower folding plate 221, that is, the lower roller 2241 on the lower connecting plate 224 can be attached to the second straight edge 2252.

[0096] An induction plate 226 is provided at one end of the lower connecting plate 224, and an induction foot 2261 is provided at the bottom edge of the induction plate 226. Two induction switches 227 corresponding to the induction feet 2261 are provided on the lower folding plate 221. The power member 240 and the clamping mechanism 300 are electrically connected to the induction switches 227. When the lower connecting plate 224 moves relative to the lower folding plate 221, the induction foot 2261 also moves synchronously with the lower connecting plate 224 to achieve the induction foot 2261 moving back and forth between the two induction switches 227; further, when the retainer 500 is in the closed state, the induction foot 2261 is located directly above the induction switch 227 close to the retainer 500, and when the clamping mechanism 300 is closed ... After the second motor 330 of 0 controls the clamping rod 321 to clamp the medicine bag, the second motor 330 transmits a signal to the first motor 241, the first motor 241 runs, the lower connecting plate moves, and when the sensing foot 2261 is located directly above the sensing switch 227 away from the clamper, the first motor 241 stops running again. At this time, the retainer 500 has been fully opened. Afterwards, when the medicine bag in the retainer 500 is heat-sealed and a new medicine bag is added, people need to control the first motor 241 to run again until the sensing foot 2261 is located directly above the sensing switch 227 close to the retainer 500, the retainer 500 clamps the new medicine bag, and the first motor 241 stops running.

[0097] The opening assembly 230 includes an upper folding plate 231 connected to the lower folding plate 221 and at least two opening rods 232 that move through the upper folding plate 231. The two opening rods 232 are connected by an upper connecting plate 233 at one end away from the retainer 500. The upper folding plate 231 is slidingly provided with an upper driving plate 234 for driving the upper connecting plate 233 to move relative to the upper folding plate 231. When the power part 240 drives the upper driving plate 234 to move relative to the upper folding plate 231, the upper driving plate 234 will push the upper connecting plate 233 to move accordingly, so that the upper connecting plate 233 can drive the opening rod 232 to move relative to the upper folding plate 231, thereby realizing that the opening rod 232 is against the clamping part on the retainer 500.

[0098] The bottom surface of the upper connecting plate 233 is provided with an upper roller 2331, and the side surface of the upper roller 2331 presses against the side edge of the upper driving plate 234 close to the retainer 500. The side edge of the upper driving plate 234 close to the retainer 500 is provided with a first oblique edge 2341 corresponding to the second straight edge 2252 and a first straight edge 2342 corresponding to the second oblique edge 2251. The upper folding plate 231 is provided with a second guide rail 2311 slidably connected to the upper driving plate 234, and the opening rod 232 is sleeved with a second spring 2321, and the second spring 2321 is stuck between the upper connecting plate 233 and the upper folding plate 231. When the power member 240 drives the upper driving plate 234 to move relative to the upper folding plate 231, the upper roller 2331 will move back and forth on the first oblique edge 2341 and the first straight edge 2342. Specifically, when the upper roller 233 When the upper connecting plate 233 is pressed against the first oblique edge 2341 and rolls toward the first straight edge 2342, the upper connecting plate 233 moves toward the retainer 500 until the opening rod 232 abuts against the clamping portion of the retainer 500. At the same time, the second spring 2321 is compressed, generating an elastic force between the upper connecting plate 233 and the upper folding plate 231, that is, enabling the upper roller 2331 on the upper connecting plate 233 to press against the first oblique edge 2341. When the upper roller 2331 rolls against the first straight edge 2342, the upper connecting plate 233 remains stationary relative to the upper folding plate 231, so that the opening rod 232 remains stationary relative to the upper folding plate 231. At the same time, due to the elastic force between the upper connecting plate 233 and the upper folding plate 231, the upper roller 2331 on the upper connecting plate 233 remains stationary relative to the first straight edge 2342.

[0099] A groove 2343 for accommodating the upper connecting plate 233 is provided on the upper driving plate 234 . The groove 2343 prevents the upper connecting plate 233 from affecting the movement of the upper driving plate 234 relative to the upper folding plate 231 .

[0100] In the present invention, the clamping claws 522 of the retainer 500 are the clamping parts of the retainer 500 .

The front shell 520 is provided with a bent plate 521 that is buckled with the pull plate 223. The two sides of the front shell 520 are hinged with the above-mentioned clamping claws 522. The number of the clamping claws 522 is the same as the number of the opening rod 232. When the first motor 241 drives the first gear 242 to rotate, the upper driving plate 234 and the lower driving plate 225 are respectively located on both sides of the first gear 242, so that the upper driving plate 234 and the lower driving plate The moving direction of 225 is opposite. Further, when the upper roller 2331 rolls on the first oblique edge 2341, the lower roller 2241 rolls on the second straight edge 2252, so that the opening rod 232 of the opening component 230 is extended until the opening rod 232 abuts against the clamping claw 522 of the retainer 500; when the upper roller 2331 rolls on the first straight edge 2342, the lower roller 2241 rolls on the second oblique edge 2251, so that the pull plate 223 of the tension component 220 drives The bending plate 521 of the retainer 500 realizes the separation of the front shell 520 and the rear shell 510 of the retainer 500, thereby realizing the opening of the retainer 500 and causing the clamping claw 522 on the retainer 500 to rotate, thereby realizing the clamping claw 522 to release the medicine bag in the retainer 500. At the same time, the third spring 512 is compressed, and there is elastic force between the front shell 520 and the rear shell 510, so that when the pull plate 223 is reset, the front shell 520 is also automatically reset by the elastic force of the third spring 512.

[0102] When the cam 522 is in the closed position, the spring 5231 is pressed against the stopper 522 and the spring 5232 is in the closed position, so that the stopper 522 is pressed against the stopper 522 and the stopper 522 is in the closed position.
