DETAILED DESCRIPTION

[0053] 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.

[0054] refer to Figure 1 and Figure 2 The medicine bag prefabrication equipment in the embodiment of the present invention may include a support seat 200, a bag taking mechanism 100, a forming mechanism 400 and a transfer mechanism 300, wherein the bag taking mechanism 100, the forming mechanism 400 and the transfer mechanism 300 are all arranged on the support seat 200. Specifically, the bag taking mechanism 100 is used to place a plurality of medicine bags 10, and the bag taking mechanism 100 includes a bag taking component (refer to Figure 2 The bag taking assembly is used to grab the medicine bag 10, and the transfer mechanism 300 is used to transfer the bag taking assembly connected to the medicine bag 10 to the forming mechanism 400. The forming mechanism 400 is used to expand and shape the medicine bag 10 so as to facilitate the subsequent loading of the medicine into the medicine bag 10.

[0055] In some embodiments, reference Figure 3 and Figure 4 The bag taking mechanism 100 further includes a rack 110, a movable plate 120 and a first driving module 130, wherein the movable plate 120 and the first driving module 130 are both disposed on the rack 110. Specifically, the rack 110 includes a bottom plate 111 and two side plates 112, the two side plates 112 are relatively disposed on the bottom plate 111, each side plate 112 has a first end and a second end opposite to each other, the first end and the second end are arranged along a first direction, and the two side plates 112 are arranged along a second direction, and the first direction is perpendicular to the second direction.

[0056] The space between the two side panels 112 can be used to accommodate a plurality of medicine bags 10, and the plurality of medicine bags 10 are stacked in sequence along the first direction and placed on the bottom panel 111. In addition, the gap between the first ends of the two side panels 112 can form a discharge port 113, and when taking out the medicine bags 10, the medicine bags 10 closest to the discharge port 113 can be taken out from the discharge port 113.

[0057] The movable plate 120 is disposed between the two side plates 112 and is located on the side of the plurality of medicine bags 10 away from the discharge port 113. At the same time, the movable plate 120 is in contact with the surface of the medicine bag 10 farthest from the discharge port 113. The first driving module 130 can be used to drive the movable plate 120 to move toward the discharge port 113 along the first direction, so that the plurality of medicine bags 10 move toward the discharge port 113. It should be understood that, on the one hand, the movable plate 120 can be used to cooperate with the storage rack 110 to support the plurality of medicine bags 10. On the other hand, after the nearest medicine bag 10 is taken from the discharge port 113, the remaining medicine bags 10 can be pushed toward the discharge port 113 by driving the movable plate 120 to move toward the discharge port 113 using the first driving module 130, thereby ensuring that there are always medicine bags 10 at the discharge port 113, and then it is convenient to take the medicine bags 10 from the discharge port 113, which is conducive to improving production efficiency.

[0058] When the movable plate 120 is in the initial state, the movable plate 120 can be located near the second end of the side plate 112, so that the distance between the movable plate 120 and the discharge port 113 is larger, and more medicine bags 10 can be accommodated. In this way, it is possible to avoid frequently placing the medicine bags 10 between the two side plates 112, so as to further improve the production efficiency.

[0059] In some embodiments, reference Figure 4 , a first guide rail 115 is provided on one side of each side plate 112 facing the other side plate 112, the first guide rail 115 extends along a first direction, and both ends of the movable plate 120 can be respectively mounted on the two first guide rails 115 through sliders, and the movable plate 120 can slide along the first direction relative to the first guide rails 115. In this embodiment, by providing the first guide rails 115, it is possible to ensure that the movable plate 120 moves along the first direction and improve the stability of the movement of the movable plate 120.

[0060] Continue to refer Figure 4 , each side plate 112 is also provided with a limiting strip 114 on one side facing the other side plate 112, the limiting strip 114 extends along the first direction, and the limiting strip 114 protrudes from the surface of the side plate 112. When a plurality of medicine bags 10 are placed between the two side plates 112, the two sides of each medicine bag 10 along the second direction are respectively in contact with the limiting strips 114 on both sides, so that the limiting strips 114 on both sides can limit the position of the medicine bag 10, ensuring that the medicine bag 10 can be stably placed on the bottom plate 111. In addition, since the medicine bag 10 is only in contact with the limiting strip 114, the contact area between the two is small, which can reduce the friction force on both sides of the medicine bag 10, so that it can be more easily pushed by the moving plate 120.

[0061] Furthermore, there may be two limit bars 114 on each side panel 112. For example, the two limit bars 114 are respectively located on both sides of the first guide rail 115, so that the two limit bars 114 on each side can contact different parts of the medicine bag 10. Since the limit bars 114 on both sides cooperate to limit the position of the medicine bag 10, the position of the medicine bag 10 can be better limited by providing the upper and lower limit bars 114.

[0062] In this embodiment, the limiting strips 114 may be arranged to protrude from the first guide rails 115, that is, the spacing between the limiting strips 114 on both sides is smaller than the spacing between the first guide rails 115 on both sides. In this way, when the medicine bag 10 is placed between the limiting strips 114 on both sides, the medicine bag 10 can be prevented from contacting the first guide rails 115, thereby preventing the first guide rails 115 from affecting the movement of the medicine bag 10.

[0063] In some embodiments, continue to refer to Figure 4 , a baffle 140 is provided at the first end of each side plate 112, and the baffle 140 protrudes from the corresponding baffle 140 toward the other side plate 112, and at this time, the gap between the baffles 140 on both sides is smaller than the gap between the two side plates 112. Specifically, the baffle 140 on each side protrudes from the limiting strip 114 on the same side, that is, the gap between the baffles 140 on both sides is also smaller than the gap between the limiting strips 114 on both sides, that is, the gap between the baffles 140 on both sides is smaller than the size of the medicine bag 10 along the second direction. The medicine bag 10 located at the discharge port 113 can be stopped by the limiting strip 114. When the medicine bag 10 is not taken out, even if the moving plate 120 has a thrust on the medicine bag 10, the medicine bag 10 will not come out of the discharge port 113 by itself. When the medicine bag 10 is taken out, although the medicine bag 10 is blocked by the baffle 140, under the action of external force, the medicine bag 10 can be deformed to a certain extent and taken out. At this time, the medicine bag 10 at the back can still be blocked by the baffle 140 due to the lack of external force, thereby preventing the medicine bag 10 at the back from being dragged out when the bag is taken out.

[0064] Furthermore, a first baffle 150 and a second baffle 160 are provided between the two side panels 112, and the two ends of the first baffle 150 are respectively connected to the two side panels 112, and the two ends of the second baffle 160 are also respectively connected to the two side panels 112, and the first baffle 150 and the second baffle 160 are arranged along the third direction. Specifically, the first baffle 150 is on the top and the second baffle 160 is on the bottom. At the same time, along the third direction, the first baffle 150 is also lower than the top of the medicine bag 10, and the second baffle 160 is higher than the bottom plate 111, so that the distance between the first baffle 150 and the second baffle 160 is smaller than the size of the medicine bag 10 along the third direction. Since the medicine bag 10 is placed on the bottom plate 111, the first baffle 150 and the second baffle 160 can also further limit the medicine bag 10. In addition, the first baffle 150 and the second baffle 160 can also cooperate with the baffle 140 to further prevent the medicine bag 10 behind from being taken out when the bag is taken out.

[0065] In this embodiment, the second stop bar 160 can also rotate relative to the bottom plate 111, so that the second stop bar 160 is higher than the bottom plate 111 or the second stop bar 160 is located on the side of the bottom plate 111 away from the first stop bar 150. In actual use, the position of the second stop bar 160 can be set according to different needs, so that it is more convenient to take the medicine bag 10.

[0066] In some embodiments, reference Figure 4 and Figure 5 , the first driving module 130 may include a first constant force spring mechanism, and the first constant force spring mechanism includes a first constant force spring 132 and a first fixed block 131. The first fixed block 131 is fixedly connected to the first end of the side plate 112, the first end of the first constant force spring 132 is fixed in the first fixed block 131, and the second end can be connected to the moving plate 120 through the first connecting plate 133. The first constant force spring 132 is always in a stretched state, so that the first constant force spring 132 generates a force that moves the second end of the first constant force spring 132 toward the first end of the first constant force spring 132, so that the first constant force spring 132 has a constant pulling force on the moving plate 120, and the moving plate 120 always has a tendency to move toward the discharge port 113. When a medicine bag 10 is taken out from the discharge port 113 , there is a gap between the remaining medicine bags 10 and the discharge port 113 . At this time, under the action of the first constant force spring 132 , the movable plate 120 can automatically move toward the discharge port 113 , thereby pushing the medicine bags 10 to move toward the discharge port 113 .

[0067] It should be understood that in this embodiment, by providing the first constant force spring 132 structure, after taking one medicine bag 10 , the movable plate 120 can be pushed to automatically move the remaining medicine bags 10 toward the discharge port 113 , thereby ensuring the high efficiency of the production operation.

[0068] In this embodiment, if Figure 4As shown, a slot 1121 may be provided on the side plate 112, the slot 1121 extending along a first direction, and the first constant force spring 132 is provided in the slot 1121. One end of the connecting plate may pass through the slot 1121 to facilitate connection with the first constant force spring 132. The provision of the slot 1121 may also facilitate ensuring the direction of the first constant force spring 132 during deformation, thereby providing a stable force on the moving plate 120.

[0069] As an implementation scheme, there may be two first constant force spring mechanisms, and the two first constant force spring mechanisms are respectively arranged on the two side plates 112. In this case, slots 1121 may be provided on both side plates 112, the middle of the connecting plate is fixed on the moving plate 120, and the two ends of the connecting plate are respectively penetrated through the two slots 1121 to facilitate connection with the first constant force springs 132 on both sides. By connecting the first constant force springs 132 on both sides by using the connecting plate, it is ensured that the two first constant force springs 132 act on the moving plate 120 at the same time, so as to further ensure that the moving plate 120 can move smoothly.

[0070] In some embodiments, reference Figure 5 and Figure 6 , the bag taking mechanism 100 in this embodiment may further include a belt 170 and a second driving module 180. Specifically, a through slot 1111 is provided in the middle of the bottom plate 111, and first transmission shafts 116 are provided at both ends of the bottom plate 111 arranged along the first direction, the axis of the first transmission shaft 116 extends along the second direction, and the two ends of the first transmission shaft 116 are respectively connected to the side walls of the through slot 1111. The belt 170 is arranged in the through slot 1111, and the belt 170 is wound around the two first transmission shafts 116. It can be understood that the belt 170 is divided into upper and lower layers of conveying parts by the two first transmission shafts 116, the two layers of conveying parts are arranged in parallel, and each layer of conveying parts extends along the first direction.

[0071] The second driving module 180 can be used to drive the belt 170 to rotate around the axis of the first transmission shaft 116, thereby driving the upper conveying part to move along the first direction. A plurality of medicine bags 10 can be placed on the upper conveying part, and when the conveying part moves along the first direction, the plurality of medicine bags 10 can be driven to move along the first direction. In other words, the medicine bags 10 and the conveying part are relatively stationary, so that no friction is generated between the bottom of the medicine bag 10 and the belt 170, thereby avoiding damage to the medicine bag 10.

[0072] For reference Figure 6 and Figure 7, the second driving module 180 may include a second constant force spring mechanism, the second constant force spring 182 structure includes a second constant force spring 182 and a second fixed block 181, and the second fixed block 181 is fixedly connected to an end of the bottom plate 111 away from the discharge port 113. When the movable plate 120 is in the initial state, the first end of the second constant force spring 182 is fixed in the second fixed block 181, and the second end is connected to the portion of the belt 170 close to the discharge port 113. The second constant force spring 182 is always in a stretched state, so that the second constant force spring 182 generates a force that moves the second end of the second constant force spring 182 toward the first end of the second constant force spring 182, so that the second constant force spring 182 has a constant pulling force on the belt 170.

[0073] The second constant force spring mechanism and the first constant force spring mechanism can be linked to each other so that the first constant force spring 132 structure and the second constant force spring mechanism move synchronously. That is, when the first constant force spring mechanism pushes the movable plate 120 to move toward the discharge port 113, the second constant force spring mechanism synchronously drives the belt 170 to rotate around the first transmission shaft 116 to drive the upper conveying part to move along the first direction toward the discharge port 113. At this time, although the movable plate 120 pushes the medicine bag 10 to move, the belt 170 also moves synchronously, so that the medicine bag 10 and the belt 170 can be relatively stationary, avoiding friction between the medicine bag 10 and the belt 170.

[0074] like Figure 7 As shown, there may be two belts 170, and the two belts 170 are arranged in the through groove 1111 of the bottom plate 111 along the second direction, and the two belts 170 are both wound around the first transmission shaft 116 on both sides. The second end of the second constant force spring 182 can be connected to the two belts 170 through the second connecting plate 183. Specifically, the second end of the second constant force spring 182 is fixedly connected to the middle of the second connecting plate 183, and the two ends of the second connecting plate 183 are respectively connected to the belts 170 on both sides, so that the second constant force spring 182 can drive the two belts 170 to synchronously rotate around the first transmission shaft 116, thereby ensuring the stability of the movement of the medicine bag 10.

[0075] In some embodiments, one of the first transmission shafts 116 can also serve as a tensioning shaft for tensioning the belt 170, thereby ensuring good performance of the belt 170. At the same time, an adjustment plate 117 can be provided on the side of the bottom plate 111 away from the side plate 112, and the adjustment plate 117 can cooperate with the tensioning shaft to adjust the tightness of the belt 170.

[0076] In some embodiments, the distance between the two side panels 112 is adjustable so that the bag taking mechanism 100 in this embodiment can be suitable for taking medicine bags 10 of different sizes. When adjusting the distance between the two side panels 112, the relative position between the side panels 112 and the bottom panel 111 can be adjusted to achieve the purpose of adjusting the distance. Exemplarily, a plurality of installation stations can be set on each side of the bottom panel 111, and the plurality of installation stations on each side are arranged along the second direction. When the distance between the two side panels 112 needs to be adjusted, the side panels 112 can be installed at different installation stations, which is simple and easy to operate.

[0077] In some embodiments, reference Figure 8 The bag taking assembly includes an adsorption module 190, and the transfer mechanism 300 may include a third driving module 310. The adsorption module 190 can be used to adsorb the medicine bag 10 located at the discharge port 113. The third driving module 310 is used to drive the adsorption module 190 to move along the second direction to transfer the adsorption module 190 from the rack 110 to the forming mechanism 400.

[0078] The adsorption module 190 includes a suction cup seat 191 and a plurality of suction cups 192, wherein the vacuum adsorption hole is provided with adsorption holes corresponding to the plurality of suction cups 192 one by one, and each suction cup 192 can be connected to the suction cup seat 191 through the corresponding adsorption hole. The suction cup seat 191 forms a negative pressure state on the surface of the suction cup 192, so that the suction cup 192 can adsorb the medicine bag 10. Specifically, the suction cup seat 191 can be a rectangular structure, the upper half of which is used to connect the suction cup 192, and the lower half can be used to connect the third driving module 310.

[0079] The plurality of vacuum suction cups 192 may be arranged along the height direction of the medicine bag 10 , so that the suction force of the plurality of vacuum suction cups 192 on various parts of the medicine bag 10 is more balanced, so that the medicine bag 10 can be better expanded.

[0080] In some embodiments, reference Fig. 9 and Fig.10, the third driving module 310 may include two parallel slide rails 311, a first stepper motor 312 and a conveyor belt 313, wherein the slide rail 311 extends along the second direction, the adsorption module 190 is connected to the support plate 314, and the two ends of the support plate 314 can be respectively installed on the two slide rails 311 through sliders. At the same time, the third driving module 310 also includes two second transmission shafts 317, which are arranged along the second direction and are respectively arranged at the two ends of the slide rail 311. The conveyor belt 313 is wound around the two second transmission shafts 317, and the first stepper motor 312 can drive the conveyor belt 313 to rotate around the second transmission shaft 317, so that the part of the conveyor belt 313 located between the two second transmission shafts 317 can move along the second direction. The support plate 314 is fixedly connected to the conveyor belt 313, and when the conveyor belt 313 rotates around the second transmission shaft, the support plate 314 can be driven to move along the second direction, that is, the adsorption module 190 can be driven to move along the second direction.

[0081] In this embodiment, the slide rail 311 can be disposed on the support seat 200 and located below the bag taking mechanism 100, so that the adsorption module 190 can reciprocate. The slide rail 311 is located at the rack 110, and the other end is located at the molding mechanism 400 to provide a sufficient travel range for the adsorption module 190. In addition, limit blocks 315 can be respectively disposed at both ends of the slide rail 311 to prevent the adsorption module 190 from being separated from the slide rail 311.

[0082] Furthermore, if Fig.10 As shown, a position sensor 316 can also be set between the two slide rails 311. The position sensor 316 can be used to detect the position signal of the adsorption module 190, so as to control the displacement of the adsorption module 190 according to the acquired position signal, so that the adsorption module 190 can accurately reach the discharge port 113 or the molding mechanism 400.

[0083] In some embodiments, reference is made to Fig. 9 and Fig.11 The transfer mechanism 300 in this embodiment may also include a fourth driving module 320, which is used to drive the adsorption module 190 to move along the first direction so that the adsorption module 190 is close to or away from the molding mechanism 400, so that the adsorption module 190 can transfer the medicine bag 10 to a preset position, which is convenient for the molding mechanism 400 to perform the molding operation on the medicine bag 10.

[0084] The fourth driving module 320 may be disposed on the support plate 314. Specifically, the fourth driving module 320 may include a second stepping motor 321, a first synchronous pulley 322, a second synchronous pulley 323, a synchronous belt 324, and a ball screw 325. The first synchronous pulley 322 and the second synchronous pulley 323 are disposed in parallel, and the synchronous belt 324 is wound around two synchronous belt 324 wheels. The second stepping motor 321 is in transmission connection with the first synchronous pulley 322 to provide power to the first synchronous pulley 322 and drive the first synchronous pulley 322 to rotate. Under the action of the synchronous belt 324, the second synchronous pulley 323 rotates. The ball screw 325 extends along the first direction and is connected to the second synchronous pulley 323. The adsorption module 190 is in transmission connection with the ball screw 325. When the second synchronous pulley 323 rotates, the ball screw 325 can be driven to move, thereby driving the adsorption module 190 to extend along the first direction.

[0085] In addition, reference Fig.12 , the support seat 200 may also be provided with an early warning bearing mounting plate 330, which may cooperate with the two synchronous belt 324 wheels to fix the two synchronous belt 324 wheels, and control the tightness of the synchronous belt 324 by adjusting the position. At the same time, the support seat 200 is also provided with an early warning positioning plate 340 for adjusting the position of the early warning bearing mounting plate 330. Specifically, the early warning positioning plate 340 is provided with a screw hole, and the early warning bearing mounting plate 330 is tightened and loosened by rotating the screw, thereby adjusting the tightness of the synchronous belt 324.

[0086] In some embodiments, reference Fig.13 and Fig.14 The forming mechanism 400 may include a cup holder 410, a forming pestle 420 and a fifth driving module 430. The cup holder 410 may be used to clamp the medicine bag 10 transferred by the transfer mechanism 300. The fifth driving module 430 may be used to drive the forming pestle 420 to move along a third direction so that the forming pestle 420 can be close to or away from the medicine bag 10.

[0087] The cup holder 410 may include two clamping blocks 411 disposed opposite to each other, and the two clamping blocks 411 may be moved closer to or farther from each other to change the gap between the two clamping blocks 411. When the cup holder 410 needs to clamp the medicine bag 10, the two clamping blocks 411 may be moved away from each other to increase the gap between the two clamping blocks 411, so as to facilitate placing the medicine bag 10 between the two clamping blocks 411. Then, the two clamping blocks 411 are moved closer to each other, and the two clamping blocks 411 cooperate to clamp the medicine bag 10.

[0088] When the transfer mechanism 300 transfers the medicine bag 10 to the cup holder 410 and the cup holder 410 clamps the medicine bag 10 , the medicine bag 10 is flat with an opening 11 at the top. At this time, the opening 11 can be regarded as a slit-like structure.

[0089] Continue to refer Fig.13 and Fig.14 The molding mechanism 400 in this embodiment may also include a molding auxiliary module, which includes an adsorption device 440, a sixth driving module 450 and a sensor module (not shown in the figure). The adsorption device 440 includes a vacuum adsorption seat 441 and a plurality of vacuum adsorption holes 442 arranged on the surface of the vacuum adsorption seat 441. Negative pressure is formed at the opening of each vacuum adsorption hole 442 so as to be able to adsorb the medicine bag 10. Specifically, when the adsorption module 190 transfers the medicine bag 10 to the cup holder 410, the adsorption module 190 and the adsorption device 440 are respectively located on the opposite sides of the medicine bag 10. At this time, the adsorption module 190 and the adsorption device 440 can simultaneously adsorb the two opposite surfaces of the medicine bag 10 so that the opening 11 of the medicine bag 10 is stretched open.

[0090] The forming pestle 420 is located above the medicine bag 10, and the fifth driving module 430 can drive the forming pestle 420 to enter the medicine bag 10 through the opening 11 of the medicine bag 10, so as to open the medicine bag 10. After the medicine bag 10 is opened and formed, the fifth driving module 430 can also be used to drive the forming pestle 420 to leave the medicine bag 10 through the opening 11 of the medicine bag 10, so that the cup holder 410 can clamp the medicine bag 10 to enter the next process.

[0091] refer to Fig.15 The forming pestle 420 in this embodiment includes a connecting rod 421 and a tapered portion 422, wherein the tip of the tapered portion 422 is close to the medicine bag 10. When the forming pestle 420 enters the medicine bag 10 from the opening 11 of the medicine bag 10, the tip of the tapered portion 422 first enters the opening 11 of the medicine bag 10. It can be understood that the tip of the tapered portion 422 first enters the opening 11, which can facilitate the gradual expansion of the medicine bag 10 during the process of the forming pestle 420 gradually entering the medicine bag 10, thereby preventing the medicine bag 10 from being torn due to excessive deformation. In addition, the tip of the tapered portion 422 is smaller in size, making it easier to enter the opening 11 of the medicine bag 10, thereby making it easier to send the forming pestle 420 into the medicine bag 10.

[0092] Reference again Fig.13 and Fig.14In this embodiment, the fifth driving module 430 may include a first fixed seat 431, a second guide rail 432, a first screw nut 433 mechanism and a first motor 434. The second guide rail 432 is disposed on the first fixed seat 431, and the first guide rail 115 extends along the first direction. The forming pestle 420 may be connected to the second guide rail 432 via a connecting rod 421, and the forming pestle 420 is transmission-connected to the first screw nut 433 mechanism. When the first motor 434 drives the first screw nut 433 mechanism to move, the first screw nut 433 mechanism can drive the forming pestle 420 to move relative to the second guide rail 432 along the first direction, thereby achieving the purpose of approaching or moving away from the medicine bag 10.

[0093] like Fig.14 As shown, when the medicine bag 10 is clamped by the cup holder 410 and the medicine bag 10 is adsorbed by the adsorption module 190 and the adsorption device 440, the adsorption module 190 and the adsorption device 440 are respectively located on opposite sides of the cup holder 410, so that the clamping effect of the clamping block 411 on the medicine bag 10 will not be affected. In addition, in order to facilitate the adsorption assembly and the adsorption device 440 to adsorb the medicine bag 10, each clamping block 411 can also be provided with an avoidance groove 4112 for avoiding the adsorption module 190 or the adsorption device 440. In this way, when the clamping block 411 clamps the medicine bag 10, the adsorption module 190 and the adsorption device 440 can also pass through the avoidance groove 4112 of the clamping block 411 to contact the surface of the medicine bag 10, thereby achieving an adsorption effect.

[0094] In this embodiment, the molding mechanism 400 may be provided with a molding station, which may be located directly below the molding pestle 420, and the sensor module may be provided in the molding station. Specifically, the sensor module may be located directly below the adsorption module 190 when the adsorption module 190 transfers the medicine bag 10 to the cup holder 410. When the sensor module detects the position of the adsorption module 190, the sixth driving module 450 may drive the adsorption device 440 to move along the second direction so that the adsorption device 440 is close to the medicine bag 10. It can be understood that before the molding pestle 420 enters the medicine bag 10, the sixth driving module 450 drives the adsorption device 440 to be close to the medicine bag 10, and at the same time cooperates with the adsorption module 190 to adsorb the surface of the medicine bag 10, so that the opening 11 of the medicine bag 10 is opened. Subsequently, when the third driving module 310 can also drive the adsorption module 190 to move toward the bag taking mechanism 100, the sensor module detects that the adsorption module 190 leaves the molding station, and the sixth driving module 450 drives the adsorption device 440 away from the medicine bag 10. At this time, the adsorption device 440 and the adsorption module 190 are both away from the medicine bag 10, which can facilitate the subsequent molding pestle 420 to enter the interior of the medicine bag 10 through the opening 11 of the medicine bag 10 and stretch the medicine bag 10 to form the medicine bag 10.

[0095] Furthermore, if Fig.14As shown, the sixth driving module 450 may include a second fixed seat 451, a third guide rail 452, a second lead screw nut mechanism 452 and a second motor 454, wherein the third guide rail 452 is disposed on the second fixed seat 451, and the third guide rail 452 extends along the second direction. The adsorption device 440 may be connected to the third guide rail 452 via a slider, and the adsorption device 440 and the second lead screw nut mechanism 452 are transmission-connected. When the second motor 454 drives the second lead screw nut mechanism 452 to move, the second lead screw nut mechanism 452 may drive the adsorption mechanism to move relative to the third guide rail 452 along the second direction.

[0096] In this embodiment, the fifth driving module 430 can also be connected to the second fixing base 451 through the first fixing base 431, so that the structure between the fifth driving module 430 and the sixth driving module 450 is compact, so as to reduce the volume of the molding structure and save space.

[0097] refer to Fig.16 In some embodiments, each clamping block 411 is provided with a V-shaped groove 4111 on one side facing another clamping block 411, and the V-shaped groove 4111 can be used to accommodate the part of the medicine bag 10 that is stretched open when the molding pestle 420 enters the medicine bag 10 and stretches the medicine bag 10 open. That is, when the molding pestle 420 enters the medicine bag 10, the two surfaces of the medicine bag 10 are deformed toward the V-shaped groove 4111 respectively until they fit with the groove wall of the V-shaped groove 4111. Due to the provision of the V-shaped groove 4111, when the medicine bag 10 is deformed under the action of the molding pestle 420, when the molding pestle 420 leaves the medicine bag 10, the V-shaped groove 4111 can help the medicine bag 10 maintain the stretched shape and prevent the medicine bag 10 from rebounding to its original shape.

[0098] It should be noted that, in the process of the molding pestle 420 entering the medicine bag 10 and stretching the medicine bag 10, the two side edges of the medicine bag 10 along the second direction will gradually move toward the center of the medicine bag 10, and at this time, the portion of the clamping block 411 that was originally used to clamp the edge of the medicine bag 10 no longer acts on the medicine bag 10. In order to ensure that the clamping block 411 always maintains the clamping effect on the medicine bag 10, a reset structure (not shown in the figure) can be provided between the two clamping blocks 411, and the reset structure can be provided on the two opposite sides of the V-shaped groove 4111 along the second direction, and the two ends of the reset structure are respectively connected to the two clamping blocks 411. The reset structure is used to generate a force that brings the two clamps 411 closer to each other. When the edge of the medicine bag 10 moves toward the V-shaped groove 4111, a gap appears between the parts of the clamps 411 that were originally used to clamp the edge of the medicine bag 10. At this time, the reset structure can make the two clamps 411 closer to each other, so that the parts of the two clamps 411 that were originally used to clamp the edge of the medicine bag 10 fit together, thereby ensuring that the two clamps 411 always have a good clamping effect on the medicine bag 10.

[0099] In this embodiment, illustratively, the reset structure can be a spring mechanism. When the two clamps 411 are in the initial state of clamping the medicine bag 10, the spring mechanism is in a stretched state. At this time, the spring mechanism generates an elastic reset force, which is used to make the two clamps 411 have a tendency to approach each other. After the molding pestle 420 opens the medicine bag 10, the parts of the two clamps 411 that were originally used to clamp the edges of the medicine bag 10 lose the supporting effect of the medicine bag 10. Under the action of the spring mechanism, the two clamps 411 can approach each other. Or, illustratively, the reset structure can also be two magnets that attract each other. In the initial state, the edge of the medicine bag 10 is located between the two magnets. When the edge of the medicine bag 10 moves toward the V-groove 4111, the edge of the medicine bag 10 leaves between the two magnets, and the two magnets attract each other, so that the two clamps 411 approach each other.

[0100] For reference Figure 2 , Fig.13 and Fig.14 In this embodiment, the medicine bag prefabrication equipment can be provided with two bag taking mechanisms 100, and correspondingly, two sets of transfer mechanisms 300 can also be provided. The discharge ports 113 of the two bag taking mechanisms 100 are opposite, so that the two sets of transfer mechanisms 300 can take bags separately without interfering with each other.

[0101] On this basis, the molding mechanism 400 can also be provided with two molding pestles 420, and the two molding pestles 420 are arranged in parallel. Correspondingly, there are also two cup holders 410 and two sensor modules, and the two sensor modules are respectively used to detect the positions of the adsorption modules 190 on both sides. It can be understood that by providing two molding pestles 420, two medicine bags 10 can be molded at the same time, which is conducive to improving production efficiency.

[0102] Specifically, the vacuum adsorption seat 441 of the adsorption device 440 may be provided with a plurality of vacuum adsorption holes 442 on both sides, and the vacuum adsorption seat 441 is located between the two cup holders 410 along the first direction. When the two sensor modules detect the positions of the two adsorption modules 190 respectively, it indicates that the two cup holders 410 both clamp the medicine bags 10, and the sixth driving module 450 drives the adsorption device 440 to move between the two cup holders 410, and uses the vacuum adsorption holes 442 on both sides to respectively adsorb the two medicine bags 10, so as to cooperate with the adsorption modules 190 on both sides to simultaneously open the openings 11 of the two medicine bags 10.

[0103] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
