Description

Technical Field

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

[0002] After a variety of Chinese medicinal materials are mixed and packed into non-woven bags, they are made into Chinese medicine bags, which can be used for stewing meat or foot soaking, etc. After the initial primary packaging of Chinese medicine bags, in order to better meet the needs of transportation and storage, they are usually processed by secondary packaging machines. Due to the various shapes of Chinese medicinal materials, such as flakes, blocks, and powders, the difference in shape makes it difficult for Chinese medicine bags to naturally adjust to a flat state when placed horizontally. In the process of Chinese medicine bags falling into large bags, due to the irregular arrangement of medicinal materials, Chinese medicine bags often appear to be placed unevenly, with some parts higher than other parts, resulting in the overall height of the Chinese medicine bags exceeding the bag mouth of the large bag. This situation not only affects the tightness of the large bag seal, but may also cause the sealing machine to fail to seal, reduce the efficiency of the packaging line, increase the rework rate during the packaging process, and have an adverse effect on the smoothness of the production process and the control of packaging costs.

[0003] For example, the patent document with the publication number CN214190460U discloses a linkage production system for packaging small bags of Chinese herbal medicines, which includes a feeding device, a Z-type elevator, a packaging machine, a slope lifting and conveying device, an online weight check and rejection device, an online traceability detection and waste rejection device, an online counting and material distribution device, and a medium bag filling device. The packaging machine packs bulk Chinese herbal medicines into small bags, and can simultaneously realize the functions of weighing, filling and heat sealing. The medium bag filling device packs a rated number of small bags into a large bag for secondary packaging. Since the system directly transports the small bags to the medium bag filling device, the diversity of the shape and volume of the medicinal materials makes it difficult for the Chinese medicine bags to be placed flat into the large bag, affecting the packaging of the large bag. Therefore, it is necessary to develop a Chinese medicine bag packaging device to solve the technical problem that in the process of packing the small bag of Chinese medicine into the large bag, the Chinese medicine bag is difficult to automatically adjust to a flat state, which is not conducive to smooth loading into the packaging bag. Summary of the invention

[0004] In view of this, the present invention provides a Chinese medicine bag packaging device to solve the technical problem that the Chinese medicine bag is difficult to automatically adjust to a flat state during the process of packaging a small bag of Chinese medicine into a large bag.

[0005] In order to solve the above technical problems, the present invention provides a Chinese medicine bag packaging device, comprising a Chinese medicine bag conveying mechanism and a sealing and cutting device arranged on a frame, the sealing and cutting device is used for heat sealing before the packaging bag is loaded into the Chinese medicine bag and sealing and cutting after the Chinese medicine bag is loaded, the Chinese medicine bag conveying mechanism comprises a conveyor belt, and the output end of the conveyor belt is provided with a moving mechanism capable of driving the Chinese medicine bag to move and a arranging mechanism for arranging the Chinese medicine bag;

[0006] The moving mechanism includes a moving plate slidably connected to the frame, a receiving frame fixedly mounted on the moving plate, a moving frame slidably mounted in the receiving frame for receiving the Chinese medicine package, and a driving component for driving the moving plate to reciprocate; the moving direction of the moving plate is perpendicular to the moving direction of the moving frame;

[0007] The arranging mechanism includes a flattening component for squeezing the traditional Chinese medicine package and an alignment component for aligning the traditional Chinese medicine package;

[0008] The flattening assembly includes a driving member for driving the moving frame to move, a connecting rod structure driven by the moving frame to deflect, and a pressing plate hinged at the end of the connecting rod structure; the driving member drives the moving frame to move to deflect the connecting rod structure, so as to drive the pressing plate to squeeze and position the Chinese medicine bag;

[0009] The alignment assembly comprises alignment plates arranged on both sides of the receiving frame and a driving unit for driving the alignment plates to move; the driving unit drives the two alignment plates to move toward a position close to the middle of the moving frame to promote the alignment of the Chinese medicine packages.

[0010] By adopting the above technical scheme, the present invention shakes the Chinese medicine bag through the moving mechanism, which is conducive to keeping the Chinese medicine bag flat and lifting the floating dust on the surface of the Chinese medicine bag. At the same time, the pressing plate assembly flattens the Chinese medicine bag, and the alignment assembly arranges and aligns the two sides of the Chinese medicine bag, which is conducive to neatly placing the Chinese medicine bag in the packaging bag and smoothly sealing the packaging bag, thereby improving the efficiency of the packaging line. Specifically, the Chinese medicine bag is transported to the mobile rack through the conveyor belt of the Chinese medicine bag conveying mechanism, and the driving assembly drives the mobile disk to reciprocate, and the mobile disk drives the receiving rack and the mobile rack to reciprocate. Due to the inertia of the reciprocating motion, the Chinese medicine bag on the mobile rack will shake, which is conducive to the flatness of the Chinese medicine bag and also conducive to lifting the floating dust on the surface of the Chinese medicine bag. The driving member of the tablet pressing assembly drives the mobile rack to move, and the mobile rack drives the connecting rod structure to deflect, and the connecting rod structure drives the pressing plate to move downward, flattening and positioning the Chinese medicine bag. At the same time, the driving unit drives the two alignment plates to gather toward the middle to align the Chinese medicine bag.

[0011] Preferably, the driving assembly includes a centring crank slider mechanism connected below the movable disk and a driving motor for driving the centring crank slider mechanism to move.

[0012] By adopting the above technical solution, the driving motor drives the centring crank slider mechanism to move, and then drives the moving disk to reciprocate. The Chinese medicine bag shakes on the moving frame fixedly connected to the moving disk, which is beneficial to the flatness of the Chinese medicine bag and also helps to lift the dust on the surface of the Chinese medicine bag.

[0013] Preferably, the receiving frame has a dropping end and a sliding end, the movable plate is located at the lower part of the sliding end and fixedly connected to the sliding end, and the driving member drives the movable frame to move to the sliding end to realize the falling of the traditional Chinese medicine package.

[0014] By adopting the above technical solution, the movable rack can slide in the receiving rack, the movable plate is located at the lower part of the sliding end and is fixedly connected to the sliding end, and there is no connection below the blanking end. In the initial position, the movable rack is located at the blanking end of the receiving rack, and the Chinese medicine package falls from the conveyor belt onto the movable rack. After the moving mechanism and the sorting mechanism shake, press and align the Chinese medicine package, the driving member drives the movable rack to slide from the blanking end to the sliding end, and the Chinese medicine package on the movable rack falls and enters the packaging bag, thereby completing the packaging.

[0015] Preferably, the movable frame includes a frame body and a push-pull rod located at the end of the frame body, both ends of the push-pull rod are fixedly connected with sliding rods, the sliding rods are perpendicular to the push-pull rods, a sliding groove is opened at the end of the frame body, the sliding rod is slidably installed in the sliding groove, one end of the sliding rod away from the push-pull rod is fixedly connected to a limit plate, and two side walls of the sliding groove are provided with blocks that can block the limit plate, the driving member drives the push-pull rod to move, and the push-pull rod drives the connecting rod mechanism to deflect.

[0016] By adopting the above technical solution, the driving member drives the push-pull rod to move, the push-pull rod drives the connecting rod mechanism to deflect, and the connecting rod mechanism drives the pressure plate to squeeze or release the Chinese medicine bag. When the Chinese medicine bag needs to be squeezed, the driving member drives the push-pull rod to move backward, the push-pull rod drives the connecting rod mechanism to deflect downward, and the pressure plate moves downward to squeeze the Chinese medicine bag. The sliding stroke of the slide bar in the slide groove allows the push-pull rod to drive the connecting rod mechanism and the pressure plate to move downward, while keeping the position of the frame and the Chinese medicine bag unchanged. After the alignment component aligns the Chinese medicine bag, the driving member drives the push-pull rod to continue to move backward, and the limit plate contacts the block. As the push-pull rod continues to move backward, the limit plate drives the block to move backward, thereby moving the frame backward to achieve the falling of the Chinese medicine bag. When resetting, the driving member drives the push-pull rod forward, and the slide bar moves forward in the slide groove until the limit plate contacts the bottom of the slide groove and pushes the frame forward to achieve the resetting of the frame.

[0017] Preferably, a support rod is fixedly installed on the top of the supporting frame, and the connecting rod mechanism includes a connecting rod 1 rotatably connected to the two ends of the support rod, and a connecting rod 2 hinged to the connecting rod 1, the connecting rod 1 is corner-shaped, and the corner is an obtuse angle, and a connecting rod is fixedly connected to the pressure plate, and the two ends of the connecting rod are respectively hinged to the connecting rod 2, and a return spring is connected between the connecting rod and the connecting rod 2, between the connecting rod 2 and the connecting rod 1, and between the connecting rod 1 and the support rod.

[0018] By adopting the above technical solution, the push-pull rod contacts the end of connecting rod 1 away from connecting rod 2 during the backward movement of the push-pull rod. As the push-pull rod moves backward, one end of connecting rod 1 deflects upward. Since connecting rod 1 is rotatably connected to the support rod and a return spring is connected between connecting rod 1 and the support rod, the other end of connecting rod 1 connected to connecting rod 2 deflects downward, thereby driving connecting rod 2 and the pressure plate to deflect downward. Since the Chinese medicine bag shakes during the downward movement of the pressure plate, the return spring between connecting rod 1 and connecting rod 2 and the return spring between connecting rod 2 and the pressure plate are conducive to the adaptive adjustment of the pressure plate according to the height of the Chinese medicine bag. At the same time, after extrusion, it is conducive to the reset of connecting rod 2 and the pressure plate.

[0019] Preferably, the driving member includes a push-pull rod lead screw arranged at the lower end of the push-pull rod, a lead screw slider connecting the push-pull rod and the push-pull rod lead screw, and a driving motor 2 installed on the movable disk to drive the push-pull rod lead screw to rotate.

[0020] By adopting the above technical solution, the second driving motor drives the push-pull rod screw to rotate, and the screw slider on the push-pull rod screw drives the push-pull rod to move, and then the push-pull rod drives the frame and the connecting rod mechanism to move, thereby realizing the flattening and falling of the Chinese medicine bag.

[0021] Preferably, the driving unit includes a rotating shaft rotatably connected to the supporting frame, a slider mounted on the rotating shaft and fixedly connected to the alignment plate, and a driving motor three for driving the rotating shaft to rotate. Both ends of the rotating shaft are respectively provided with external threads with opposite thread rotation directions, and the slider is provided with an internal thread matching the external thread. The motor three drives the rotating shaft to rotate so as to drive the two sliders to move closer to or away from each other, thereby driving the two alignment plates to move closer to or away from each other, and the axial direction of the rotating shaft is perpendicular to the direction of movement of the alignment plate.

[0022] By adopting the above technical solution, the driving motor drives the rotating shaft to rotate. Since the spiral directions of the external threads at both ends of the rotating shaft are opposite, the two sliders are moved closer to or away from each other, thereby driving the two alignment plates closer to or away from each other. When the two alignment plates are close to each other, the Chinese medicine package on the frame is pushed to be aligned in the center, which is conducive to the sealing and cutting device to smoothly seal the packaging bag after the Chinese medicine package falls into the packaging bag.

[0023] Preferably, a baffle for limiting the position of the Chinese medicine package is provided at one end of the blanking end close to the sliding end, the baffle and both ends of the blanking end are fixedly connected, a gap is left between the baffle and the blanking end, a connecting piece is fixedly connected between the sliding block and the alignment plate, and the connecting piece passes through the gap.

[0024] By adopting the above technical solution, when the Chinese medicine bag falls, the frame moves backward, and the baffle blocks and limits the Chinese medicine bag, so that the Chinese medicine bag falls smoothly after the frame moves backward.

[0025] Preferably, a rotating shaft is provided at intervals in the middle part of the frame, and the rotating shaft and the frame are rotatably connected so that the Chinese medicine package that falls from the conveyor belt onto the rotating shaft moves to the middle part of the frame under the action of inertia.

[0026] By adopting the above technical solution, after the Chinese medicine package falls from the conveyor belt onto the frame, it contacts the rotating shaft, which is conducive to the Chinese medicine package moving smoothly to the middle part of the frame under the action of inertia.

[0027] Preferably, the sorting mechanism also includes a dust removal component, which includes an air outlet arranged on the pressure plate, an air outlet source for supplying air to the blowing port, an air intake port arranged on the frame, and an air intake source for providing negative pressure to the air intake port. The airflow blown out from the blowing port can blow away the floating dust fallen on the Chinese medicine package, and the air intake source absorbs the airflow mixed with floating dust through the air intake port.

[0028] By adopting the above technical solution, the dust removal component and the moving component cooperate, and when the Chinese medicine bag is shaken, the air flow blown out from the air port can blow away the floating dust on the Chinese medicine bag, which is beneficial to keeping the Chinese medicine bag clean. The suction source sucks away the air flow mixed with floating dust through the air suction port, which is beneficial to reducing the floating dust falling into the air.

[0029] The beneficial effects of the above technical solution of the present invention are as follows:

[0030] 1. The present invention shakes the Chinese medicine bag through a moving mechanism, which is beneficial to keeping the Chinese medicine bag flat and lifting the floating dust on the surface of the Chinese medicine bag. At the same time, the pressing plate assembly flattens the Chinese medicine bag, and the alignment assembly arranges and aligns the two sides of the Chinese medicine bag, which is beneficial to neatly place the Chinese medicine bag in the packaging bag and smoothly seal the packaging bag, thereby improving the efficiency of the packaging line.

[0031] 2. A plurality of reset springs are arranged between the connecting rod mechanism and the pressing plate of the present invention, which is conducive to the adaptive adjustment of the pressing plate according to the height of the Chinese medicine bag during the shaking of the Chinese medicine bag. At the same time, after squeezing, it is conducive to the reset of the connecting rod mechanism and the pressing plate.

[0032] 3. The dust removal component of the present invention cooperates with the moving component. When the Chinese medicine bag is shaken, the air flow blown out from the air port can blow away the floating dust on the Chinese medicine bag, which is beneficial to keeping the Chinese medicine bag clean.

[0041] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 7 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0042] Example

[0043] This embodiment provides a Chinese medicine packaging device, such as Figure 1 As shown, it includes a frame 1, a Chinese medicine bag conveying mechanism 8, and a packaging bag conveying mechanism 9. The Chinese medicine bag conveying mechanism 8 includes a conveyor belt 81 for conveying the Chinese medicine bag. The packaging bag conveying mechanism 9 is used to convey the packaging bag.

[0044] like Figure 1 As shown, a folding device 2, a sealing and cutting device 3, a moving component 4 and a feeding device 5 are provided on the frame 1.

[0045] like Figure 1 As shown, the folding device 2 can fold the two sides of the packaging bag conveyed by the packaging bag conveying mechanism 9, and a feeding port for the Chinese medicine bag is left at the folding position.

[0046] like Figure 1 As shown, the sealing and cutting device 3 includes a heat sealing component 31 and a sealing and cutting component 32. The heat sealing component 31 is used to heat seal the two sides of the packaging bag after folding it. After the Chinese medicine bag falls into the packaging bag, the sealing and cutting component 32 seals and cuts the ends of the packaging bag, so that the upper end of the packaging bag after the Chinese medicine packaging bag and the lower end of the next packaging bag without the Chinese medicine bag are sealed at the same time, and after sealing, the middle part of the two packaging bags can be cut to separate the two packaging bags. Both the folding device 2 and the sealing and cutting device 3 are existing technologies and will not be described in detail.

[0047] like Figure 1 As shown, the moving assembly 4 includes a horizontal moving member 41 and a vertical moving member 42, and a receiving plate 65 is connected to the vertical moving member 42, and the receiving plate 65 is used to receive the Chinese medicine bag. The horizontal moving member 41 and the vertical moving member 42 are both screw transmissions to achieve horizontal and vertical movement of the receiving plate 65, so as to transport the Chinese medicine bag on the conveyor belt 81 to the top of the Chinese medicine bag loading port, so that the Chinese medicine bag falls into the packaging bag. The screw transmission is a prior art and will not be described in detail.

[0048] like Figure 1 and Figure 2 As shown, the unloading device 5 is located below the sealing and cutting device 3 , and the unloading device 5 includes a unloading component 51 and a turning component 52 .

[0049] like Figure 1 and Figure 2 As shown, the unloading assembly 51 includes an unloading conveyor belt 1 511 arranged in parallel on the left and right, an unloading conveyor belt 2 512, an unloading plate 513 arranged between the two conveyor belts, and an unloading cylinder 514 for driving the unloading plate 513 to move up and down.

[0050] like Figure 1 and Figure 2As shown, the belt surfaces of the first unloading conveyor belt 511 and the second unloading conveyor belt 512 face each other and are perpendicular to the left and right directions, and a gap is left between the first unloading conveyor belt 511 and the second unloading conveyor belt 512, and the unloading plate 513 is located in the gap, and the plate surface of the unloading plate 513 is perpendicular to the up and down directions. The packaging bag is located in the gap between the first unloading conveyor belt 511 and the second unloading conveyor belt 512, and the unloading plate 513 supports the bottom of the packaging bag to reduce damage to the packaging bag.

[0051] like Figure 2 As shown, the turning assembly 52 includes a turning plate 521 , a clamping cylinder 522 and a turning cylinder 523 .

[0052] like Figure 1 and Figure 2 As shown, the flip plate 521 is hinged on the frame 1, the plate surface of the flip plate 521 is perpendicular to the up and down direction, the unloading conveyor belt 1 511 is slidably installed in the middle part of the flip plate 521, and the unloading conveyor belt 2 512 is fixedly installed on the left end of the flip plate 521, and a cavity that enables the unloading plate 513 to move up and down is provided on the flip plate 521 in the middle of the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512.

[0053] like Figure 2 As shown, the clamping cylinder 522 is horizontally arranged on the flip plate 521 and is located at the lower part of the unloading conveyor belt 1 511. The clamping cylinder 522 drives the unloading conveyor belt 1 511 to move left and right to increase or decrease the distance between the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512.

[0054] like Figure 1 and Figure 2 As shown, the flip cylinder 523 is tiltedly arranged below the flip plate 521 and is hinged on the frame 1 , and the output shaft of the flip cylinder 523 is hinged to the right end of the flip plate 521 .

[0055] like Figure 1 and Figure 2 As shown, the packaging bag falls between the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512, and the unloading cylinder 514 drives the unloading plate 513 to rise. As the Chinese medicine bags continue to fall into the packaging bag, the unloading cylinder 514 drives the unloading plate 513 to continue to descend until the packaging bag is full. The sealing and cutting device 3 completes the sealing and cutting, and the clamping cylinder 522 is started. The unloading conveyor belt 1 511 moves to the left to clamp the packaging bag containing the Chinese medicine bags. The flipping cylinder 523 is started to make the flipping plate 521 tilt downward, thereby driving the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512 to tilt downward. The clamping cylinder 522 drives the unloading conveyor belt 1 511 to move, so that the distance between the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512 is increased, and the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512 are started to transport the packaging bag to the next process.

[0056] like Figure 2 As shown, the output shaft of the flip cylinder 523 contracts and drives the unloading plate 513 to flip downward, thereby flipping the packaged Chinese medicine package downward, so that the packaged Chinese medicine package can fall horizontally onto the next conveying device.

[0057] like Figure 1 As shown, a moving mechanism 6 and a sorting mechanism 7 are provided on the frame 1 and at a position below the output end of the conveyor belt 81 of the traditional Chinese medicine bag conveying mechanism 8.

[0058] like Figure 1 and Figure 3 As shown, the moving mechanism 6 includes a moving plate 61 , a receiving frame 62 , a moving frame 63 and a driving assembly 64 .

[0059] like Figure 1 and Figure 3 As shown, the movable plate 61 is slidably connected to the receiving plate 65 and can slide in the front-rear direction.

[0060] like Figure 4 As shown, the receiving frame 62 is fixedly mounted on the movable plate 61 , and the receiving frame 62 has a blanking end 621 and a sliding end 622 , the blanking end 621 is located on the right side of the sliding end 622 , and the movable plate 61 is fixedly mounted below the sliding end 622 .

[0061] like Figure 1 and Figure 4 As shown, the moving frame 63 is slidably installed in the receiving frame 62, and the moving frame 63 can slide in the left and right directions. The moving frame 63 is used to receive the Chinese medicine bag dropped from the conveyor belt 81. The moving assembly 4 drives the receiving plate 65 to move, and then drives the moving plate 61, the receiving frame 62 and the moving frame 63 to move above the Chinese medicine bag loading port. The moving frame 63 slides from the blanking end 621 to the sliding end 622, so that the Chinese medicine bag falls from the blanking end 621 to the Chinese medicine bag loading port, thereby realizing the packaging of the Chinese medicine bag.

[0062] like Figure 3 As shown, the driving assembly 64 includes a centring crank slider mechanism 641 and a driving motor 642.

The driving motor 1 642 drives the centrifugal crank slider mechanism 641 to move, thereby driving the moving plate 61, the receiving frame 62 and the moving frame 63 to move back and forth. Due to the inertia of the reciprocating motion, the Chinese medicine bag on the moving frame 63 will shake, which is conducive to the leveling of the Chinese medicine bag and also conducive to the dust on the surface of the Chinese medicine bag. The driving motor 1 642 is a stepping motor, and the two collinear positions of the centrifugal crank slider mechanism 641 are the two extreme positions of the moving plate 61. Since the two collinear rotation angles of the centrifugal crank slider mechanism 641 are 180°, when the rotation angle is 90°, the moving plate 61 is in the middle position, which is convenient for the Chinese medicine bag falling from the conveyor belt 81 to fall smoothly onto the moving frame 63. The stepper motor can control the rotation angle through a pulse signal, thereby controlling the positions of the moving plate 61 and the moving frame 63 .

[0064] like Figure 1 As shown, the finishing mechanism 7 includes a flattening component 71 (such as Figure 4 As shown), alignment component 72 (as Figure 5 ) and dust removal assembly 73 (as shown Figure 5 as shown).

[0065] like Figure 4 and Figure 5 As shown, the flattening component 71 is used to squeeze and position the Chinese medicine bag on the movable frame 63, the alignment component 72 is used to align the two sides of the Chinese medicine bag, and the dust removal component 73 is used to remove the floating dust scattered on the Chinese medicine bag.

[0066] like Figure 4 As shown, the flattening assembly 71 includes a driving member 711 , a connecting rod mechanism 712 and a pressing plate 713 .

[0067] like Figure 4 As shown, the driving member 711 is used to drive the moving frame 63 to move. Specifically, as Figure 6 and Figure 7 As shown, the mobile frame 63 includes a frame body 631 and a push-pull rod 632 located at the left end of the frame body 631. The Chinese medicine bag is placed on the frame body 631, the axis of the push-pull rod 632 extends in the front-to-back direction, and the mobile frame 63 slides in the left-to-right direction. The two ends of the push-pull rod 632 are fixedly connected with a slide rod 634, the axis of the slide rod 634 extends in the left-to-right direction, the left end of the frame body 631 is provided with a slide groove 636, the slide rod 634 is slidably installed in the slide groove 636, the right end of the slide rod 634 is fixedly connected with a limit plate 635, and the two side walls of the slide groove 636 are provided with a block 637 that can block the limit plate 635, and the driving member 711 drives the push-pull rod 632 to move.

[0068] like Figure 1 and Figure 6 As shown, a rotating shaft 633 is provided at intervals in the middle part of the frame 631, and the axis of the rotating shaft 633 extends in the front-to-back direction. The rotating shaft 633 and the frame 631 are rotatably connected so that the Chinese medicine package that falls from the conveyor belt 81 onto the rotating shaft 633 can move to the middle part of the frame 631 under the action of inertia.

[0069] like Figure 4 As shown, the driving member 711 includes a push-pull rod screw 7111, a screw slider 7112 and a driving motor 2 7113.

[0070] like Figure 4 As shown, the push-pull rod lead screw 7111 is rotatably connected to the receiving frame 62, the axis of the push-pull rod lead screw 7111 extends in the left-right direction, the lead screw slider 7112 is sleeved on the push-pull rod lead screw 7111, and the lead screw slider 7112 and the push-pull rod 632 are fixedly connected.

[0071] like Figure 4 As shown, the second drive motor 7113 is fixedly installed on the movable plate 61. The second drive motor 7113 drives the push-pull rod screw 7111 to rotate, driving the screw slider 7112 and the push-pull rod 632 to slide along the push-pull rod screw 7111, thereby driving the push-pull rod 632 to move, thereby moving the frame 631.

[0072] like Figure 4 As shown, the connecting rod mechanism 712 includes a connecting rod 1 7121 and a connecting rod 2 7122 .

[0073] like Figure 4 As shown, a support rod 714 is provided on the receiving frame 62 at the middle part between the blanking end 621 and the sliding end 622. The axis of the support rod 714 extends in the front-back direction, and the two ends of the support rod 714 are fixedly connected to the receiving frame 62. There are two connecting rods 7121, which are rotatably connected to the two ends of the support rod 714. The connecting rod 1 7121 is corner-shaped, with an obtuse corner and an opening facing downward. There are also two connecting rods 7122, which are respectively hinged on the ends of the connecting rod 1 7121 away from the support rod 714.

[0074] like Figure 4 As shown, a connecting rod 715 is fixedly connected to the pressure plate 713 , and the connecting rod 715 is parallel to the support rod 714 . One end of the two connecting rods 7122 away from the connecting rod 1 7121 is hinged at both ends of the connecting rod 715 .

[0075] like Figure 4 As shown, a return spring is connected between the connecting rod 715 and the second connecting rod 7122, between the second connecting rod 7122 and the first connecting rod 7121, and between the first connecting rod 7121 and the supporting rod 714. The return spring is a torsion spring.

[0076] When the Chinese medicine package needs to be squeezed, Figure 4As shown, the drive motor 2 7113 drives the push-pull rod screw 7111 to rotate, driving the screw slider 7112 and the push-pull rod 632 to move to the left along the push-pull rod screw 7111, and then driving the push-pull rod 632 to move to the left. During the movement of the push-pull rod 632 to the left, it contacts the end of the connecting rod 1 7121 away from the connecting rod 2 7122. As the push-pull rod 632 moves to the left, one end of the connecting rod 1 7121 deflects upward. Since the connecting rod 1 7121 is rotatably connected to the support rod 714 and a return spring is connected between the connecting rod 1 7121 and the support rod 714, the other end of the connecting rod 1 7121 connected to the connecting rod 2 7122 deflects downward, thereby driving the connecting rod 2 7122 and the pressing plate 713 to deflect downward, and the pressing plate 713 moves downward to squeeze the Chinese medicine bag. The sliding stroke of the sliding rod 634 in the sliding groove 636 allows the push-pull rod 632 to drive the connecting rod mechanism 712 and the pressing plate 713 to move downward, so that the position of the frame 631 and the Chinese medicine bag remains unchanged. Figure 4 and Figure 5 As shown, after the alignment assembly 72 aligns the Chinese medicine package, the driving motor 2 7113 drives the push-pull rod 632 to continue to move left, and the limit plate 635 contacts the stopper 637. As the push-pull rod 632 continues to move left, the push-pull rod 632 is located at the left end of the connecting rod 1 7121, and the limit plate 635 drives the stopper 637 to move left, thereby causing the frame 631 to move left and realize the falling of the Chinese medicine package. When resetting, the driving motor 2 7113 drives the push-pull rod 632 to move right, and the slide bar 634 moves right in the slide slot 636 until the limit plate 635 contacts the bottom of the slide slot 636 and then pushes the frame 631 to move right, until the push-pull rod 632 is located at the right end of the connecting rod 1 7121, and the connecting rod mechanism 712, the pressing plate 713 and the frame 631 are reset.

[0077] like Figure 5 As shown, the alignment assembly 72 includes an alignment plate 721 and a driving unit 722 .

[0078] like Figure 5 As shown, the driving unit 722 includes a rotating shaft 7221, a slider 7222 and a driving motor 3 7223.

[0079] like Figure 4 and Figure 5 As shown, the rotating shaft 7221 is rotatably connected to the receiving frame 62 at the middle position between the sliding end 622 and the blanking end 621 , the rotating shaft 7221 is parallel to the support rod 714 , and both ends of the rotating shaft 7221 are respectively provided with external threads with opposite thread rotation directions.

[0080] like Figure 5 As shown, two sliders 7222 are provided, which are respectively located at two ends of the rotating shaft 7221 , and each slider 7222 is provided with an internal thread matching the external thread.

[0081] like Figure 5As shown, the driving motor three 7223 is fixedly installed on the moving plate 61, and the driving motor three 7223 drives the rotating shaft 7221 to rotate.

[0082] like Figure 5 As shown, two alignment plates 721 are provided, which are arranged in parallel front and back on both sides of the upper part of the blanking end 621, and two sliders 7222 are fixedly connected to the two alignment plates 721 through connecting members 724, respectively, and the connecting members 724 are rod-shaped.

[0083] like Figure 5 As shown, a baffle 723 is provided in the middle of the blanking end 621 and the sliding end 622. The baffle 723 is located above the rotating shaft 7221 and parallel to the rotating shaft 7221. The baffle 723 and both ends of the blanking end 621 are fixedly connected. A gap is left between the baffle 723 and the blanking end 621, and the connecting member 724 passes through the gap. When the Chinese medicine package falls, the frame 631 moves left, and the baffle 723 blocks and limits the Chinese medicine package, so that after the frame 631 moves left, the Chinese medicine package falls smoothly.

[0084] like Figure 5 As shown, the driving motor 3 7223 drives the rotating shaft 7221 to rotate. Since the spiral directions of the external threads at both ends of the rotating shaft 7221 are opposite, the two sliders 7222 are moved closer to or away from each other, thereby driving the two alignment plates 721 to move closer to or away from each other. When the two alignment plates 721 move closer to each other, the Chinese medicine package on the frame 631 is pushed to be aligned in the center, which is conducive to the sealing and cutting device 3 to smoothly seal the packaging bag after the Chinese medicine package falls into the packaging bag.

[0085] like Figure 5 As shown, the dust removal assembly 73 includes an air outlet 731, an air outlet source, an air intake port 732 and an air intake source; the air outlet source and the air intake source are Figure 5 Not marked in.

[0086] like Figure 5 As shown, there are multiple air outlets 731, all of which are arranged on the pressure plate 713. The pressure plate 713 is provided with an air outlet channel connected to the air outlet 731. The air outlet channel is connected to a bellows, which is connected to an air outlet source. The airflow blown out from the air outlet can blow away the floating dust on the Chinese medicine bag.

[0087] like Figure 5 As shown, there are also multiple air inlets 732, all of which are arranged on the frame 631. The frame 631 is provided with an air intake channel connected to the air inlet 732. The air intake channel is connected to a bellows, and the bellows is connected to an air intake source. The air intake source absorbs the airflow mixed with floating dust through the air inlet 732.

[0088] The method of using this embodiment is as follows:

[0089] The packaging bag conveying mechanism 9 conveys the packaging bag, the folding device 2 folds the two sides of the packaging bag, the heat sealing component 31 heats the two sides of the folded packaging bag together, and the sealing and cutting component 32 seals and cuts the lower end of the packaging bag. The moving component 4 drives the frame 631 to move below the output end of the conveyor belt 81, and the driving motor 1 642 drives the centering crank slider mechanism 641 to move, so that the frame 631 is located in the middle of the receiving plate 65, and the two Chinese medicine bags on the conveyor belt 81 fall onto the frame 631, and the moving component 4 drives the frame 631 to move downward.

[0090] The driving motor 642 drives the centring crank slider mechanism 641 to move, thereby driving the moving plate 61, the receiving frame 62 and the moving frame 63 to move back and forth. Due to the inertia of the reciprocating motion, the Chinese medicine bag on the moving frame 63 will shake, which is beneficial to the flatness of the Chinese medicine bag and also helps to raise the dust on the surface of the Chinese medicine bag.

[0091] The driving motor 2 7113 drives the push-pull rod screw 7111 to rotate, driving the screw slider 7112 and the push-pull rod 632 to move to the left along the push-pull rod screw 7111, and then driving the push-pull rod 632 to move to the left. During the movement of the push-pull rod 632 to the left, it contacts the end of the connecting rod 1 7121 away from the connecting rod 2 7122. As the push-pull rod 632 moves to the left, one end of the connecting rod 1 7121 deflects upward. Since connecting rod 1 7121 is rotatably connected to support rod 714 and a return spring is connected between connecting rod 1 7121 and support rod 714, the other end of connecting rod 1 7121 connected to connecting rod 2 7122 deflects downward, thereby driving connecting rod 2 7122 and pressure plate 713 to deflect downward, and pressure plate 713 moves downward to squeeze the Chinese medicine bag. The sliding stroke of the slide rod 634 in the slide groove 636 allows the push-pull rod 632 to drive the connecting rod mechanism 712 and pressure plate 713 to move downward, thereby keeping the positions of the frame 631 and the Chinese medicine bag unchanged.

[0092] The driving motor 3 7223 drives the rotating shaft 7221 to rotate. Since the spiral directions of the external threads at both ends of the rotating shaft 7221 are opposite, the two sliders 7222 are close to each other, and then drive the two alignment plates 721 to approach each other. The two alignment plates 721 push the Chinese medicine package on the frame 631 to be aligned in the center, which is conducive to the sealing and cutting device 3 to smoothly seal the packaging bag after the Chinese medicine package falls into the packaging bag.

[0093] The airflow blown out from the air port can blow away the floating dust on the Chinese medicine bag, and the suction source sucks away the airflow mixed with the floating dust through the suction port 732.

[0094] After the alignment plate 721 aligns the Chinese medicine bag, the driving motor 3 7223 drives the rotating shaft 7221 to rotate in the opposite direction, so that the two sliders 7222 move away from each other, and then drives the two alignment plates 721 away from each other, so that the alignment plates 721 return to the initial position.

[0095] The moving assembly 4 drives the frame 631 to move to the upper end of the Chinese medicine bag discharge port, the discharge cylinder 514 drives the discharge plate 513 to rise, the driving motor 2 7113 drives the push-pull rod 632 to continue to move left, and the limit plate 635 contacts the stopper 637. As the push-pull rod 632 continues to move left, the limit plate 635 drives the stopper 637 to move left, so that the frame 631 moves left, and the Chinese medicine bag falls into the packaging bag. When resetting, the driving motor 2 7113 drives the push-pull rod 632 to move right, and the slide bar 634 moves right in the slide slot 636 until the limit plate 635 contacts the bottom of the slide slot 636 and pushes the frame 631 to move right, and the connecting rod mechanism 712, the pressure plate 713 and the frame 631 are reset.

[0096] Repeat the above steps until multiple layers of Chinese medicine bags are stacked in the packaging bag. As the Chinese medicine bags continue to fall into the packaging bag, the unloading cylinder 514 drives the unloading plate 513 to continuously descend until the packaging bag is full. The sealing and cutting device 3 completes the sealing and cutting, and the clamping cylinder 522 is started. The unloading conveyor belt 1 511 moves to the left to clamp the packaging bag containing the Chinese medicine bags. The flipping cylinder 523 is started to make the flipping plate 521 tilt downward, thereby driving the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512 to tilt downward. The clamping cylinder 522 drives the unloading conveyor belt 1 511 to move, so that the distance between the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512 is increased, and the unloading conveyor belt 1 511 and the unloading conveyor belt 2 512 are started to transport the packaging bag to the next process.
