Description

Technical Field

[0001] The invention relates to the technical field of pharmaceuticals, and in particular to a traditional Chinese medicine packaging machine. Background Art

[0002] Traditional Chinese medicine packaging is an important link to ensure the quality, safety and convenience of traditional Chinese medicines and Chinese patent medicines during transportation, storage and use. With the development of modernization of traditional Chinese medicine, traditional Chinese medicine packaging technology is also constantly improving to meet higher quality standards and market demands. In the existing technology, traditional Chinese medicine packaging generally relies on manual operation, which is labor-intensive, inefficient and costly. Summary of the invention

[0003] The objects of the present invention include, for example, providing a traditional Chinese medicine packaging machine, which can improve the automated operation process, improve the operation efficiency, and reduce the packaging cost.

[0004] The embodiments of the present invention can be implemented as follows:

[0005] In a first aspect, the present invention provides a traditional Chinese medicine packaging machine, comprising:

[0006] A frame and a conveying mechanism, a feeding mechanism and a sealing mechanism all arranged on the frame; the conveying mechanism is used to carry and convey the packaging bag along a first direction; the feeding mechanism is used to store medicine and can add medicine to the packaging bag located on the conveying mechanism; the sealing mechanism includes a baffle bar, a moving unit, a folding unit and a sealing unit, the baffle bar is installed on the frame, and the baffle bar is used to block the packaging bag conveyed by the conveying mechanism; the moving unit is installed on the frame, and the folding unit and the sealing unit are both installed on the moving unit, and the moving unit is used to drive the folding unit and the sealing unit to move, the folding unit is used to fold the bag opening of the packaging bag downward at the baffle bar, and the sealing unit is used to fix the folded part and the main body part formed on both sides of the baffle bar after the packaging bag is folded.

[0007] In an optional embodiment, the conveying mechanism includes a conveyor belt and a positioning unit, the conveyor belt is used to carry and drive the packaging bag to move along the first direction; the positioning unit is installed on the conveyor belt, and the positioning unit is used to contact the packaging bag located on the conveyor belt to prevent the packaging bag from tipping over.

[0008] Based on the above solution, the conveyor belt carries and drives the packaging bag to move, which is flexible to control. During the transportation of the packaging bag, the positioning unit is used to limit the posture of the packaging bag on the conveyor belt to prevent the packaging bag from tipping over. The medicine in the packaging bag is not easy to fall out, and the transportation is safer.

[0009] In an optional embodiment, the positioning unit includes a base, a first telescope and two baffles, the base is fixed on the conveyor belt, the first telescope is fixed on the base, the two baffles are slidably matched with the base, the two baffles are located on the same side of the base and are arranged at intervals, and a positioning channel is defined between the two baffles; the first telescope is simultaneously connected to the two baffles, and is used to drive the two baffles to slide in a second direction perpendicular to the first direction, so that the two baffles can switch between positions above the conveyor belt or on the sides of the conveyor belt.

[0010] Based on the above scheme, in the initial state, the two baffles are located above the conveyor belt, and a positioning channel is formed between the two baffles. When the drug is transported into the packaging bag by the feeding mechanism, the packaging bag is always in the positioning channel. The packaging bag is not easy to tip over during the falling process of the drug, and the feeding process is safe and reliable. After the feeding is completed, in the process of transporting the packaging bag by the conveyor belt, the baffle is still above the conveyor belt, and approaches the sealing mechanism together with the conveyor belt. The packaging bag is not easy to tip over during the transportation process, and the transportation process is safe and reliable. At the same time, during the sealing process, the packaging bag is still in the positioning channel. Under the action of the folding unit and the sealing unit, the packaging bag is not easy to tip over, and the sealing process is safe and reliable. After the sealing is completed, when the packaging bag needs to be removed, at this time, the first telescopic device works to drive the two baffles to retreat and leave the conveyor belt. The packaging bag is not restricted by the two baffles, which is convenient for removal.

[0011] In an optional embodiment, the feeding mechanism includes a second telescopic device, a hopper, a discharge pipe and a control valve, the second telescopic device is mounted on the frame, the hopper is mounted on the telescopic end of the second telescopic device, the discharge pipe is connected to the hopper, and the control valve is mounted on the discharge pipe to adjust the on-off state of the discharge pipe; the second telescopic device is used to adjust the distance between the hopper and the packaging bag.

[0012] Based on the above scheme, when it is necessary to add medicine, after the position of the packaging bag on the conveyor belt is determined, the bag mouth of the packaging bag is opened, the hopper is lowered by the second telescopic device, the port of the discharge pipe is extended into the packaging bag, and the hopper props up the packaging bag, and the control valve is opened, so that the medicine can easily enter the packaging bag. After the medicine is added, the second telescopic device is used to drive the hopper to rise and leave the packaging bag, and the packaging bag can move to the sealing mechanism under the action of the conveyor belt.

[0013] In an optional embodiment, the moving unit includes a third telescope and a main board, the third telescope is installed on the frame, the main board is installed on the telescopic end of the third telescope, the folding unit is installed on the main board, and the sealing unit is installed on the folding unit, and the third telescope is used to drive the folding unit and the sealing unit to rise and fall synchronously.

[0014] Based on the above scheme, after the medicine in the packaging bag is filled, the packaging bag is driven by the conveyor belt to approach the stop bar. Before that, the third telescopic device drives the main board to rise, and the sealing unit and the folding unit are not on the moving path of the packaging bag. When the packaging bag moves to contact the stop bar, the conveyor belt stops working, and the third telescopic device drives the folding unit to descend, so that the folding unit is on the side of the packaging bag away from the stop bar, which is convenient for the subsequent folding and sealing actions.

[0015] In an optional embodiment, the folding unit includes a fourth telescope and a folding plate, the fourth telescope is installed at the bottom of the main board, the folding plate is provided with a folding groove, the folding plate is installed at the telescopic end of the fourth telescope, and the notch of the folding groove faces the conveying mechanism; the folding groove is used to engage with the packaging bag and the baffle when the third telescope drives the folding plate to descend, so that part of the bag body of the packaging bag is folded relative to the baffle with the bag opening facing downward to form the folded part.

[0016] Based on the above scheme, when the folding plate is on the side of the packaging bag away from the baffle rod, the fourth telescopic device drives the folding plate to approach the baffle rod, so that the part of the packaging bag located on the upper part of the baffle rod is folded toward the side of the baffle rod. When the folding plate moves to the point where the folding groove is directly opposite to the baffle rod, that is, the folding groove is located above the baffle rod, at this time, the third telescopic device descends, driving the folding plate to descend, so that the packaging bag and the baffle rod are clamped in the folding groove together, and the packaging bag is folded with the baffle rod as a fulcrum, forming a folding part and a main part located on both sides of the baffle rod. The bag mouth is located at the folding part and faces downward. At this time, the folding of the packaging bag is completed, and the whole process is highly automated and easy to operate.

[0017] In an optional embodiment, the folding unit further includes a fifth telescopic device, a guide rod, a tightening plate and an elastic member; the fifth telescopic device is mounted on the folding plate and is located on one side of the folding groove; the guide rod and the folding plate are slidably matched in the first direction; the tightening plate is sleeved on the guide rod and is slidably matched with the guide rod in a third direction perpendicular to the first direction; the elastic member is connected to the tightening plate and the guide rod at the same time, so as to make the tightening plate have a movement tendency along the third direction and away from the conveying mechanism;

[0018] The telescopic end of the fifth telescopic device is connected to the tightening plate, and the telescopic end of the fifth telescopic device is slidably matched with the tightening plate in the third direction; the fifth telescopic device is used to drive the tightening plate to move along the first direction, so that the tightening plate drives the folding part to approach the main body part, and the tightening plate moves in the third direction under the guidance of the blocking rod, so that the folding part fits the outer surface of the blocking rod.

[0019] Based on the above scheme, when the packaging bag is folded, the folding part and the main part are located on both sides of the baffle bar, and there is a certain distance between the two separated by the baffle bar. Directly using the sealing unit for sealing may easily cause the folding part to move upward, resulting in poor sealing effect. Therefore, before sealing, the fifth telescopic device is first operated, and the fifth telescopic device drives the tightening plate close to the baffle bar, so that the tightening plate contacts the folding part and drives the folding part close to the main part. During the movement of the tightening plate, it is restricted by the baffle bar, and the tightening plate moves to the right and downward at the same time, so that the folding part is close to the lower surface of the baffle bar, and the gap between the folding part and the baffle bar is small, and the folding part is not easy to move upward and deform. When sealing, the contact area between the folding part and the sealing unit is large, the contact area between the folding part and the main part is large, and the sealing effect is good.

[0020] In an optional embodiment, the sealing unit includes two heat-sealing plates arranged opposite to each other, and both of the two heat-sealing plates are slidably matched with the folding plate and are located on two opposite sides of the folding groove.

[0021] Based on the above solution, the folding part and the main body part are pressed and heat-sealed together by bringing the two heat-sealing plates closer to each other, and the sealing operation is convenient and reliable.

[0022] In an optional embodiment, there are multiple baffle bars; the sealing mechanism also includes a rotating rod and a rotating disk, the rotating rod is rotatably connected to the frame, the rotating disk is installed on the top of the rotating rod, and multiple baffle bars are installed on the rotating disk and are arranged at intervals in the circumferential direction of the rotating disk; one of the multiple rotating rods can be selectively rotated to the top of the conveying mechanism.

[0023] Based on the above scheme, when one of the baffles cooperates with the packaging bag to complete the sealing operation of the packaging bag, the baffle plate withdraws from the top of the conveying bag, the rotating rod rotates, and the multiple baffles and the packaging bags on the baffles are driven to rotate through the turntable, and the packaging bags leave the conveyor belt. During this process, the conveyor belt can move in the opposite direction, so that the baffle plate moves to the bottom of the feeding mechanism, which is conducive to the next positioning of the packaging bag. After the baffle bar with the packaging bag leaves the conveyor belt, the new baffle bar moves to the top of the conveyor belt, which can block the new packaging bag, which is conducive to subsequent sealing.

[0024] In an optional embodiment, each of the rotating rods is rotatably matched with the rotating disk, so that an end of the rotating rod away from the rotating disk is lower than an end of the rotating rod connected to the rotating disk.

[0025] Based on the above solution, when the packaging bag leaves the conveyor belt driven by the baffle bar after packaging, the baffle bar can rotate downward, and under the action of gravity, the packaging bag can slide downward along the baffle bar, and the packaging bag can automatically leave the baffle bar for easy picking.

[0026] The beneficial effects of the embodiments of the present invention include, for example:

[0027] In summary, the Chinese medicine packaging machine provided in this embodiment, when it is necessary to package medicines, first place the packaging bag on the conveying mechanism, the conveying mechanism is in a stopped state, the feeding mechanism is opened, and the medicine is discharged into the packaging bag by using the feeding mechanism. When the amount of medicine in the packaging bag is sufficient, the feeding mechanism is closed, the conveying mechanism is opened, and the conveying mechanism drives the packaging bag to move toward the sealing mechanism. The packaging bag first contacts the baffle rod. At this time, the conveying mechanism is stopped, and the folding unit moves, so that part of the packaging bag is folded around the baffle rod, and part of the packaging bag is folded toward one side of the baffle rod to form a folded part. The part of the packaging bag located on the conveying mechanism is the main part, and the folded part and the main part are located on both sides of the baffle rod. Then, the sealing mechanism is used to fix the folded part and the main part together to achieve sealing. The whole process has a high degree of automation, low labor intensity, high efficiency, and low packaging cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0044] In the prior art, when Chinese medicinal materials are packaged, they are generally placed in bags manually, and then sealed by a sealing machine. The entire process involves a lot of manual labor, high labor intensity, low efficiency, and high packaging costs.

[0045] In view of this, the designer provides a traditional Chinese medicine packaging machine, which can improve the degree of automation of medicinal material packaging, thereby reducing labor intensity, improving packaging efficiency and reducing packaging costs.

[0046] It is worth noting that in the following embodiments, unless otherwise specified, the first direction 001, the second direction 002 and the third direction 003 are perpendicular to each other. The first direction 001 can be understood as Figure 1 The left and right directions in the second direction 002 can be understood as Figure 2 The up and down directions in the third direction 003 can be understood as Figure 1 The up and down directions in .

[0047] Please combine Figure 1-Figure 7 In this embodiment, the Chinese medicine packaging machine includes a frame 100 and a conveying mechanism 200, a feeding mechanism 300 and a sealing mechanism 400 all arranged on the frame 100; the conveying mechanism 200 is used to carry and convey the packaging bag 004 along the first direction 001; the feeding mechanism 300 is used to store medicine and can add medicine to the packaging bag 004 located on the conveying mechanism 200; the sealing mechanism 400 includes a blocking rod 410, a moving unit 420, a folding unit 430 and a sealing unit 440, the blocking rod 410 is installed on the frame 100, and the blocking rod 410 is used to block the packaging bag 004 conveyed by the conveying mechanism 200; the moving unit 420 is installed on the frame 100, and the folding unit 430 and the sealing unit 440 are both installed on the moving unit 420. The moving unit 420 is used to drive the folding unit 430 and the sealing unit 440 to move. The folding unit 430 is used to fold the bag opening of the packaging bag 004 downward at the blocking rod 410, and the sealing unit 440 is used to fix the folded part 041 and the main part 042 formed on both sides of the blocking rod 410 after the packaging bag 004 is folded.

[0048] As mentioned above, the working mode of the traditional Chinese medicine packaging machine provided in this embodiment is as follows:

[0049] Please combine Figure 3-Figure 7When the medicine needs to be packaged, the packaging bag 004 is first placed on the conveying mechanism 200, the conveying mechanism 200 is in a stopped state, the feeding mechanism 300 is opened, and the medicine is discharged into the packaging bag 004 by the feeding mechanism 300. When the amount of medicine in the packaging bag 004 is sufficient, the feeding mechanism 300 is closed, the conveying mechanism 200 is opened, and the conveying mechanism 200 drives the packaging bag 004 to move to the left close to the sealing mechanism 400. The packaging bag 004 contacts the blocking rod 410. At this time, the conveying mechanism 200 is stopped, and the folding unit 430 moves to fold part of the packaging bag 004 around the blocking rod 410. The part of the packaging bag 004 folds toward one side of the blocking rod 410 to form a folded part 041. The part of the packaging bag 004 located on the conveying mechanism 200 is the main body 042. The folded part 041 and the main body 042 are located on both sides of the blocking rod 410. Figure 7 As can be seen from the perspective shown, the folded portion 041 is located on the left side of the main portion 042, and the top of the folded portion 041 and the top of the main portion 042 are connected together and located above the blocking rod 410. Then, the folded portion 041 and the main portion 042 are fixed together by the sealing mechanism 400 to achieve sealing. The whole process has a high degree of automation, low labor intensity, high efficiency, and low packaging cost. After packaging is completed, the packaging bag 004 can be removed from the blocking rod 410.

[0050] The following embodiments illustrate the detailed structure of the traditional Chinese medicine packaging machine provided in this application by way of examples.

[0051] In this embodiment, the conveying mechanism 200 optionally includes a conveyor belt 210 and a positioning unit 220. The conveyor belt 210 is driven by at least two groups of rollers, and one of the at least two groups of rollers can be driven by a motor. The conveyor belt 210 is used to carry and drive the packaging bag 004 to move along the first direction 001. When in use, the packaging bag 004 is placed above the conveyor belt 210. The positioning unit 220 is installed on the conveyor belt 210, and the positioning unit 220 is used to contact the packaging bag 004 located on the conveyor belt 210 to prevent the packaging bag 004 from tipping over. In the initial state, Figure 1 As can be seen from the perspective shown, the blocking rod 410 is located on the left side of the packaging bag 004 , and the conveying mechanism 200 conveys the packaging bag 004 containing the medicine from right to left, so that the packaging bag 004 is close to the blocking rod 410 .

[0052] It should be understood that the conveyor belt 210 carries and drives the packaging bag 004 to move, which is flexible to operate. During the transportation of the packaging bag 004, the positioning unit 220 is used to limit the posture of the packaging bag 004 on the conveyor belt 210 to prevent the packaging bag 004 from tipping over. The medicine in the packaging bag 004 is not easy to fall out, and the transportation is safer and more reliable.

[0053] Please combine Figure 1 , Figure 4 and Figure 5 Optionally, the positioning unit 220 includes a base 221, a first retractor 222 and two baffles 223. The conveyor belt 210 is an annular structure, and the conveyor belt 210 has an upper belt body and a lower belt body, and the packaging bag 004 is placed on the upper belt body. The base 221 is fixed to the upper belt body of the conveyor belt 210, and the first retractor 222 is fixed to the base 221. The retracting direction of the first retractor 222 is consistent with the second direction 002. The two baffles 223 are both slidably matched with the base 221 in the second direction 002. The two baffles 223 are both located on the top side of the base 221 and are arranged at intervals in the first direction 001, so that a positioning channel 2231 is defined between the two baffles 223. The first telescoping device 222 is connected to the two baffles 223 at the same time, and is used to drive the two baffles 223 to slide in the second direction 002 , so that the two baffles 223 are switched between being located above the conveyor belt 210 or being located at the side of the conveyor belt 210 .

[0054] That is to say, in the initial state, Figure 1 The two baffles 223 are located on the right side of the conveyor belt 210, and the first retractor 222 is located on the right side of the two baffles 223. At this time, the two baffles 223 are not located above the conveyor belt 210, but are located on the side of the conveyor belt 210. When the packaging bag 004 is needed to hold the medicine, the first retractor 222 is started to drive the two baffles 223 to move to the left above the conveyor belt 210. At this time, a positioning channel 2231 is formed above the conveyor belt 210. Then, the packaging bag 004 is placed in the positioning channel 2231 to play a role in positioning and preventing dumping. When the feeding mechanism 300 is used to transport the medicine into the packaging bag 004, the packaging bag 004 is always in the positioning channel 2231. The packaging bag 004 is not easy to dump during the falling process of the medicine, and the feeding process is safe and reliable. After the filling is completed, during the process of conveying the packaging bag 004 by the conveyor belt 210, the two baffles 223 are still above the conveyor belt 210. As the conveyor belt 210 and the base plate approach the sealing mechanism 400, the packaging bag 004 is limited by the baffles 223 during the conveying process and is not easy to fall over, so the conveying process is safe and reliable. At the same time, during the sealing process, the two baffles 223 are still above the conveyor belt 210, and the packaging bag 004 is also in the positioning channel 2231. When the folding unit 430 and the sealing unit 440 perform corresponding operations, the packaging bag 004 is not easy to fall over, and the sealing process is safe and reliable. After the sealing is completed, when the packaging bag 004 needs to be removed, at this time, the first telescopic device 222 works, driving the two baffles 223 to slide back and reset to the right relative to the base 221, leaving the top of the conveyor belt 210, and the packaging bag 004 is not limited by the two baffles 223, so it is easy to remove.

[0055] In this embodiment, optionally, the feeding mechanism 300 includes a second telescopic device 310, a hopper 320, a discharge pipe 330 and a control valve 340. The second telescopic device 310 is mounted on the frame 100, and the telescopic direction of the second telescopic device 310 is consistent with the third direction 003. The hopper 320 can be a conical cylinder, and the material can automatically fall under the action of gravity, which is convenient for discharge and saves energy. The hopper 320 can be installed at the telescopic end of the second telescopic device 310, the discharge pipe 330 is connected to the bottom of the hopper 320, and the control valve 340 is installed on the discharge pipe 330 to adjust the on and off of the discharge pipe 330, thereby realizing the regulation of the drug discharge state. The second telescopic device 310 is used to drive the hopper 320 to reciprocate and rise and fall in the third direction 003, thereby adjusting the distance between the hopper 320 and the packaging bag 004.

[0056] With such a design, when it is necessary to add medicine, the packaging bag 004 is located in the positioning channel 2231 formed by the two baffles 223 on the conveyor belt 210 and is located directly below the hopper 320. The bag mouth of the packaging bag 004 is in an open state. The hopper 320 is lowered by the second telescopic device 310, and the port of the discharge pipe 330 extends into the packaging bag 004. The side walls of the hopper 320 support the packaging bag 004 so that the bag mouth of the packaging bag 004 is in an open state. Then, the control valve 340 is opened, and the medicine is discharged from the hopper 320 into the discharge pipe 330 and then into the packaging bag 004. After the medicine is added, the hopper 320 is driven to rise by the second telescopic device 310 and leave the packaging bag 004. The packaging bag 004 can move to the sealing mechanism 400 under the action of the conveyor belt 210.

[0057] Please combine Figure 1 and Figure 4 In this embodiment, optionally, the moving unit 420 includes a third telescope 421 and a main board 422. The third telescope 421 is installed on the frame 100. The telescopic direction of the third telescope 421 is consistent with the third direction 003, that is, the second telescope 310 and the third telescope 421 are basically arranged in parallel, and the two are arranged at intervals in the first direction 001. The main board 422 is installed at the telescopic end of the third telescope 421, the folding unit 430 is installed on the main board 422, and the sealing unit 440 is installed on the folding unit 430. The third telescope 421 is used to drive the folding unit 430 and the sealing unit 440 to rise and fall synchronously.

[0058] It should be understood, please refer to Figure 4As shown, in the initial state, the folding unit 430 and the sealing unit 440 are located above the blocking rod 410 and on the right side of the blocking rod 410. When the medicine in the packaging bag 004 is filled, the packaging bag 004 moves to the left close to the blocking rod 410 under the drive of the conveyor belt 210. The sealing unit 440 and the folding unit 430 are located at a higher position and are not on the moving path of the packaging bag 004. The folding unit 430 and the sealing unit 440 will not prevent the packaging bag 004 from approaching the blocking rod 410. When the packaging bag 004 moves to contact the right side of the blocking rod 410, the conveyor belt 210 stops working at this time, and the third telescopic device 421 drives the folding unit 430 to descend, so that the folding unit 430 is on the side of the packaging bag 004 away from the blocking rod 410, and the packaging bag 004 is located between the blocking rod 410 and the folding unit 430, so that the folding unit 430 and the sealing unit 440 can be used for the subsequent corresponding operations.

[0059] Please combine Figure 4 and Figure 5 Optionally, the folding unit 430 includes a fourth telescoping device 431 and a folding plate 432. The fourth telescoping device 431 is installed at the bottom of the main board 422. The telescopic direction of the fourth telescoping device 431 is consistent with the first direction 001. A folding groove 4321 is provided on the plate surface of the folding plate 432. The folding groove 4321 can be a rectangular through groove. The groove width of the folding groove 4321 is greater than the diameter of the blocking rod 410. The folding plate 432 is installed at the telescopic end of the fourth telescoping device 431, and the notch of the folding groove 4321 faces the conveying mechanism 200, that is, the notch of the folding groove 4321 faces. At the same time, the folding plate 432 is located on the left side of the fourth telescoping device 431, that is, the folding plate 432 is closer to the blocking rod 410 than the fourth telescoping device 431. The folding groove 4321 is used to engage with the packaging bag 004 and the baffle 410 when the third telescopic device 421 drives the folding plate 432 to descend, so that part of the bag body of the packaging bag 004 is folded with the bag opening facing downward relative to the baffle 223 to form a folded portion 041.

[0060] It should be understood that after the packaging bag 004 is conveyed to contact with the blocking rod 410 by the conveyor belt 210, the third telescopic device 421 is used to drive the folding plate 432 downward so that the lower side of the folding plate 432 is slightly higher than the top of the blocking rod 410. The dimension of the folding plate 432 higher than the top of the blocking rod 410 can be the same as the thickness of the packaging bag 004. The thickness of the packaging bag 004 can be understood as the dimension of the packaging bag 004 when it is not filled with medicine and is in a flattened state. Then, the fourth telescopic device 431 is used to drive the folding plate 432 close to the packaging bag 004. The fourth telescopic device 431 continuously drives the folding plate 432 close to the blocking rod 410, so that the portion of the packaging bag 004 located on the upper part of the blocking plate 223 moves toward the left side of the blocking rod 410 under the drive of the folding plate 432, and the folding action begins. When the folding plate 432 moves to the point where the folding groove 4321 is directly opposite to the blocking rod 410, that is, the folding groove 4321 is located above the blocking rod 410, the third telescopic device 421 descends, driving the folding plate 432 to descend, so that the packaging bag 004 and the blocking rod 410 are clamped together in the folding groove 4321, and the packaging bag 004 is folded with the blocking rod 410 as a fulcrum to form a folding part 041 and a main part 042 located on both sides of the blocking rod 410. The bag mouth is located at the folding part 041 and faces downward, and at this point, the folding of the packaging bag 004 is completed, and the entire process is highly automated and easy to operate.

[0061] It should be noted that the blocking rod 410 can be a cylindrical rod, which is not easy to damage the packaging bag 004.

[0062] Please combine Figure 4 and Figure 5 Further, the folding unit 430 further includes a fifth telescopic device 433, a guide rod 434, a tightening plate 435 and an elastic member 436. The fifth telescopic device 433 is mounted on the folding plate 432 and is located on the side of the folding plate 432 where the folding groove 4321 is provided. The telescopic direction of the fifth telescopic device 433 is consistent with the first direction 001. The folding plate 432 is provided with a sliding groove 4322 extending in the first direction 001. The sliding groove 4322 can be a dovetail groove or a T-shaped groove. One end of the guide rod 434 is located in the sliding groove 4322 and is slidably matched with the folding plate 432 in the first direction 001. The guide rod 434 is relatively fixed with the folding plate 432 in the third direction 003. The tightening plate 435 is sleeved on the guide rod 434 and is slidably matched with the guide rod 434 in the third direction 003 perpendicular to the first direction 001. The elastic member 436 is connected to the tightening plate 435 and the guide rod 434 at the same time, and is used to make the tightening plate 435 have a tendency to move along the third direction 003 and away from the conveying mechanism 200, that is, the elastic member 436 can make the tightening plate 435 have a tendency to move upward.

[0063] The telescopic end of the fifth telescopic device 433 is connected to the tightening plate 435, and the telescopic end of the fifth telescopic device 433 is slidably matched with the tightening plate 435 in the third direction 003. Specifically, a guide groove 4351 may be provided on the left side of the tightening plate 435, and the guide groove 4351 may be a dovetail groove or a T-shaped groove, and the telescopic end of the fifth telescopic device 433 is slidably matched with the guide groove 4351 in the third direction 003. The fifth telescopic device 433 can drive the tightening plate 435 to move along the first direction 001, and when the tightening plate 435 pushes the folding part 041 to approach the main part 042, the right side of the tightening plate 435 contacts the blocking rod 410, and the tightening plate 435 moves downward at the same time under the guidance of the blocking rod 410, so that the folding part 041 is attached to the outer surface of the blocking rod 410.

[0064] With such a design, when the packaging bag 004 is folded, the folded portion 041 and the main portion 042 are located on both sides of the blocking rod 410, and the blocking rod 410 separates the folded portion 041 and the main portion 042 from each other to form a certain distance therebetween. If the sealing unit 440 is directly used for sealing, the folded portion 041 may move upward, resulting in a poor sealing effect. Therefore, before sealing, the fifth retractor 433 is operated first, and the fifth retractor 433 drives the tightening plate 435 to approach the blocking rod 410, so that the tightening plate 435 is in contact with the folded portion 041. The folding part 041 is touched and driven to approach the main part 042. During the movement of the tightening plate 435, it is restricted by the blocking rod 410. The tightening plate 435 moves to the right and downward at the same time, so that the folding part 041 is close to the lower surface of the blocking rod 410. The gap between the folding part 041 and the blocking rod 410 is small, and the folding part 041 is not easy to move upward and deform. When sealing, the contact area between the folding part 041 and the sealing unit 440 is large, and the contact area between the folding part 041 and the main part 042 is large, and the sealing effect is good.

[0065] It should be understood that the elastic member 436 may be a spring.

[0066] In this embodiment, optionally, the sealing unit 440 includes two heat-sealing plates 441 arranged opposite to each other, and both heat-sealing plates 441 are slidably matched with the folding plate 432 and are located on opposite sides of the folding groove 4321. It should be understood that the heat-sealing plate 441 can adopt an existing known structure, and in order to avoid repeated description, it is not described in detail here. The two heat-sealing plates 441 are brought close to each other to press the folding part 041 and the main body part 042 together, and the sealing operation is convenient and reliable. The two heat-sealing plates 441 are located below the tightening plate 435 and on both sides of the folding groove 4321, and can clamp and heat-seal the folding part 041 and the main body part 042. Each heat-sealing plate 441 can be driven by a corresponding telescopic cylinder.

[0067] Please combine Figure 2In this embodiment, optionally, the number of the blocking rods 410 is multiple. The sealing mechanism 400 also includes a rotating rod 450 and a rotating disk 460. The rotating rod 450 is rotatably connected to the frame 100. The rotating rod 450 can be driven by a motor to rotate around a vertical axis, and the extension direction of the vertical axis is consistent with the third direction 003. The rotating disk 460 is installed on the top of the rotating rod 450, and the multiple blocking rods 410 are all installed on the rotating disk 460 and are arranged at intervals in the circumferential direction of the rotating disk 460. One of the multiple rotating rods 450 can be selectively rotated to the top of the conveying mechanism 200.

[0068] With such a design, when one of the baffles 410 cooperates with the packaging bag 004 to complete the sealing operation of the packaging bag 004, the baffle plate 223 withdraws from the top of the conveying bag, and the rotating rod 450 rotates, driving the multiple baffles 410 and the packaging bag 004 on the baffle plates 410 to rotate through the rotating disk 460, and the packaging bag 004 leaves the conveyor belt 210. During this process, the conveyor belt 210 can move in the reverse direction, so that the baffle plate 223 moves to the bottom of the feeding mechanism 300, which is convenient for the next positioning of the packaging bag 004. After the baffle plate 410 with the packaging bag 004 leaves the conveyor belt 210, the new baffle plate 410 moves to the top of the conveyor belt 210, which can block the new packaging bag 004, which is convenient for subsequent sealing.

[0069] Furthermore, each rotating rod 450 is rotatably matched with the rotating disk 460, so that the end of the rotating rod 450 away from the rotating disk 460 is lower than the end of the rotating rod 450 connected to the rotating disk 460. When the packaged bag 004 leaves the conveyor belt 210 driven by the blocking rod 410, the blocking rod 410 can rotate downward, and the packaging bag 004 can slide downward along the blocking rod 410 under the action of gravity, and the packaging bag 004 can automatically slide away from the blocking rod 410 from the end of the blocking rod 410, which is convenient for taking and placing.

[0070] It should be understood that after a packaging bag 004 is sealed, the rotating rod 450 is rotated to drive the packaging bag 004 to leave the conveyor belt 210. At this time, the conveyor belt 210 can move in the opposite direction to reset the positioning unit 220 to be located below the hopper 320, so as to facilitate the positioning of a new packaging bag 004.

[0071] The traditional Chinese medicine packaging machine provided in this embodiment has a high degree of automation, low labor intensity, high efficiency, and high packaging quality. The medicine is not easy to leak from the bag mouth, and transportation and storage are safe and reliable.

[0072] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
