[0008] As a preferred solution, the labeling lifting seat is fixed to the labeling rack through a vertical guide rod and a connecting seat, the connecting seat is fixed on the labeling rack, the vertical guide rod vertically passes through the connecting seat and is sleeved with a buffer spring, and the lower end of the vertical guide rod is fixed to the labeling lifting seat.

[0009] As a preferred solution, the labeling lifting seat is also provided with a positioning device for positioning the label on the suction plane.

[0010] As a preferred solution, the positioning device includes a positioning block arranged on the labeling lifting seat, the positioning block is located on the downstream side of the belt conveyor, and the positioning block protrudes downward from the suction plane.

[0011] As a preferred solution, the labeling lifting seat is also provided with a label detection sensor for detecting whether the label is in place.

[0012] As a preferred solution, a receiving groove for receiving the belt is further provided on the suction plane, and the belt is located in the receiving groove and partially exposed.

[0013] As a preferred solution, the packaging and bagging mechanism includes a first diaphragm unwinding wheel and a second diaphragm unwinding wheel rotatably mounted on the machine base. A pair of edge-sealing wheels are rotatably mounted below the first diaphragm unwinding wheel and the second diaphragm unwinding wheel. The pair of edge-sealing wheels are driven by an edge-sealing motor to rotate towards each other. A pair of sealing shafts are rotatably mounted on the machine base below the pair of edge-sealing wheels. The pair of sealing shafts are driven by a sealing motor to rotate towards each other. A cooperating cutting blade shaft and a cutter seat shaft are rotatably mounted on the machine base below the sealing shafts. The cutting blade shaft and the cutter seat shaft are driven by the sealing motor to rotate towards each other. The outlet of the liquid outlet pipe extends above the pair of sealing shafts. A liquid level sensor for detecting the liquid level of the liquid discharged from the liquid outlet pipe is further provided on the machine base.

[0014] After adopting the above technical solution, the effects of the present invention are as follows: Since the labeling mechanism includes a labeling base fixed on the machine base, a labeling lifting seat is vertically and liftably mounted on the labeling base. A vacuum suction cup is mounted on the labeling lifting seat. The bottom of the vacuum suction cup is a suction plane. A plurality of suction holes are provided on the vacuum suction cup. A suction chamber communicating with the suction holes is provided at the upper end of the vacuum suction cup. The suction chamber communicates with a suction power device. A label printer is fixedly mounted on the machine base. The printing outlet of the label printer faces the vacuum suction cup. A driving pulley and a driven pulley are rotatably mounted on the labeling lifting seat. A plurality of discrete belts are provided between the driving pulley and the driven pulley. The belts are connected to the printing outlet to convey the labels from the printing outlet to the suction plane of the vacuum suction cup. A label conveying motor drivingly connected to the driving pulley is mounted on the labeling lifting seat. A blocking and positioning structure is provided on the machine base on the right side of the labeling mechanism. The labeling lifting seat is driven to lift by a labeling lifting power device. Therefore, when the decoction medicine bag is filled and packaged, it will fall onto the conveyor belt. The conveyor belt can convey in both forward and reverse directions. Before the new decoction medicine packaging, the first two medicine bags need to be discarded, so that the inside of the pipeline of the integrated machine can be flushed to avoid the pollution of the previous decoction medicine. The flap guiding mechanism can change the falling direction of the decoction medicine bag. When it faces the left side, the conveyor belt conveys to the left to remove the decoction medicine bag. During normal packaging, the decoction medicine bag conveys to the right. The blocking and positioning mechanism blocks the decoction medicine bag to stay at the labeling station. Then, a part of the labels output from the printing outlet of the label printer will enter below the vacuum suction cup and be adsorbed, thus avoiding the labels from falling. Due to the conveying action of the belts, the labels output from the printing outlet are completely conveyed to the suction plane. Then, the labeling lifting power device drives the labeling lifting seat to descend, thereby completing the labeling of the decoction medicine bag. After the labeling is completed, it is output from the machine shell through the conveyor belt. The whole packaging and labeling process is very fast, the labeling position is accurate, and the efficiency and accuracy of labeling are improved.

[0015] Furthermore, since the blocking and positioning structure includes a positioning lifting seat vertically slidably installed on the machine base, a vertically arranged positioning plate is arranged on the positioning lifting seat, and the positioning plate extends downward to the top of the conveyor belt, the labeling lifting power device drives the positioning lifting seat and the labeling lifting seat to rise and fall in a synchronous direction. A vertically extending positioning rack is fixed on the positioning lifting seat, and the positioning rack is installed on the labeling base through a vertical guide rail. A labeling rack parallel to the positioning rack is fixed on the labeling lifting seat, and the labeling rack is installed on the labeling base through a vertical guide rail. A driving gear that meshes with the labeling rack and the positioning rack is rotatably installed on the labeling base, and the driving gear is transmission-connected with the labeling lifting power device. Therefore, the labeling lifting power device drives the driving gear to rotate, and the rotation of the driving gear will drive the labeling rack and the positioning rack to move. When the positioning rack moves downward, the labeling rack will be driven to move upward. When the positioning is completed, the driving gear rotates in the opposite direction. At this time, the positioning rack will move upward, and the labeling rack will descend to stick the label on the soup medicine bag. In this way, after adopting the above structure, costs can be saved, and one set of power can realize the labeling and positioning of the soup medicine bag.

[0016] Furthermore, since the positioning lifting seat is provided with a strip hole extending along the conveying direction of the conveyor belt, a fastening screw is installed in the strip hole, and the positioning lifting seat is detachably fixed to the bottom of the positioning rack by the fastening screw. Therefore, the position of the positioning lifting seat can be adjusted through the strip hole and the fastening screw, and then the position where the soup medicine bag is positioned and stopped can be adjusted to ensure that it matches the position of the vacuum suction cup.

[0017] Furthermore, since the labeling lifting seat is fixed to the labeling rack through a vertical guide rod and a connecting seat, the connecting seat is fixed on the labeling rack, the vertical guide rod vertically penetrates the connecting seat and is sleeved with a buffer spring, the lower end of the vertical guide rod is fixed to the labeling lifting seat, so that the labeling lifting seat drives the vacuum suction cup to descend for labeling, it will elastically contact with the soup medicine bag to avoid damage to the soup medicine bag due to excessive pressure.

[0018] Since the labeling lifting seat is also provided with a positioning device for positioning the label on the suction plane, the positioning device includes a positioning block arranged on the labeling lifting seat, and the positioning block is located on the downstream side of the belt conveyor, and the positioning block protrudes downward from the suction plane. Therefore, the positioning block can accurately position and block the label, so that the label can accurately enter the specified position and be conveniently attached to the soup medicine bag. At the same time, due to the existence of the positioning block, the edge of the soup medicine bag will be squeezed to a certain extent when the positioning block descends, so that the middle part of the soup medicine bag is more bulging, so that the label between the soup medicine bag and the label is more firmly attached.

[0019] Also, since a receiving groove for receiving the belt is provided on the suction plane, and the belt is located within the receiving groove with a part thereof exposed, the receiving groove can ensure the accurate operation of the belt, reduce the offset error, and at the same time, the receiving groove can partially accommodate the belt, so that only a part of the belt is exposed, thus meeting the conveying requirements and providing sufficient vacuum suction force.

[0020] Also, since a label detection sensor for detecting whether the label is in place is provided on the labeling lifting seat, the label detection sensor can detect whether there is a label at the bottom of the vacuum chuck, ensuring the accuracy of the labeling operation.

[0030] The present invention will be further described in detail below through specific embodiments.

[0031] As Figures 1 to 7 shown, a decoction packaging and labeling integrated machine includes a machine base 1, on which a medicine storage barrel 2 is fixedly installed. An outlet pipe 12 is arranged at the bottom of the medicine storage barrel 2, and a liquid adding pipe 4 is arranged at the top of the medicine storage barrel 2. A heating device can be arranged on the medicine storage barrel 2 for heat preservation; the liquid adding pipe 4 at the top of the medicine storage barrel 2 can be connected to the liquid outlet of an automatic decoction machine, and the decocted decoction can be directly fed into the medicine storage barrel 2. Of course, a cleaning pipe orifice 3 is also arranged on the medicine storage barrel 2 for connecting clean water for cleaning. Correspondingly, a liquid discharge port is also arranged at the bottom of the medicine storage barrel 2 to facilitate liquid discharge and cleaning.

[0032] A packaging and bagging mechanism 5 is arranged on the machine base 1 below the liquid adding pipe 4. A conveyor belt 6 driven by a conveying power device to convey forward and backward is installed below the bagging and packaging mechanism. A flap guiding mechanism 7 for guiding the decoction bags after packaging and bagging to the left or right is arranged on the machine base 1 between the conveyor belt 6 and the packaging and bagging mechanism 5.

[0033] In this embodiment, the conveying power device is a servo motor, which can drive the conveyor belt 6 to convey forward and backward. Taking Figure 1 as an example, the rightward direction of the conveyor belt 6 is the normal packaging and labeling conveying direction, and the leftward direction is the rejection direction.

[0034] The tipping and discharging mechanism includes a material guiding flap which is rotatably mounted on the machine base 1 through a deflection shaft, and the deflection shaft is driven by a deflection power device which can be a deflection cylinder or a motor.

[0035] As Figure 1 , Figure 2 and Figures 5 to 7 shown, the packaging and bagging mechanism 5 includes a first film unwinding wheel 51 and a second film unwinding wheel 52 rotatably mounted on the machine base 1. The first film and the second film forming the decoction bag are respectively placed in rolls on the first film unwinding wheel 51 and the second film unwinding wheel 52 and are drawn.

[0036] Below the first film unwinding wheel 51 and the second film unwinding wheel 52, a pair of edge-sealing wheels 53 are rotatably mounted. The pair of edge-sealing wheels 53 are driven by an edge-sealing motor 59 to rotate towards each other. Among them, the edge-sealing motor 59 drives a pair of edge-sealing wheels 53 to rotate towards each other through a first gear transmission mechanism 512. The structures of the two edge-sealing wheels 53 are the same. The edge-sealing wheel 53 is a hollow wheel, and a heating rod is inserted into the center to provide the heat energy for edge-sealing. The edge-sealing wheel 53 includes edge-sealing rings 54 arranged at intervals, and the edge-sealing rings 54 are in contact with each other to seal the two sides of the first film and the second film. The area between the edge-sealing rings 54 forms a filling area for accommodating the decoction. The liquid outlet pipe 12 extends and inserts into the filling area. A liquid level sensor 511 for detecting the liquid level of the liquid discharged from the liquid outlet pipe 12 is also arranged on the machine base 1. Similarly, the liquid level sensor 511 also inserts into the filling area to detect the liquid level height of the filled decoction.

[0037] Below the pair of edge-sealing wheels 53 on the machine base 1, a pair of sealing shafts 55 are rotatably mounted. The pair of sealing shafts 55 are driven by a sealing motor 510 to rotate towards each other. The sealing shaft 55 is also a hollow wheel and is heated by inserting a heating rod. The sealing shaft 55 is a flat shaft structure. Opposite sealing surfaces 56 are arranged on the sealing shaft 55, and the other areas of the sealing shaft 55 are flat. Then when the sealing shaft 55 rotates 180°, the sealing surfaces 56 will cooperate and contact once, so that sealing can be carried out once.

[0038] Below the sealing shaft 55 on the machine base 1, a cooperating cutting blade shaft 58 and a cutter seat shaft 57 are rotatably mounted. The cutting blade shaft 58 and the cutter seat shaft 57 are driven by the sealing motor 510 to rotate towards each other. The outlet of the liquid outlet pipe 12 extends above the pair of sealing shafts 55. The sealing motor 510 drives the sealing shaft 55, the cutting blade shaft 58 and the cutter seat shaft 57 to rotate through a second gear transmission mechanism 513. The position where the cutter cuts is exactly the middle part of the sealing area, so as to ensure that the decoction bags above and below are sealed each time of cutting.

[0039] AsFigure 3 and Figure 4 As shown in Figure 4 , a labeling mechanism 8 is provided on the machine base 1 on the right side of the flap feeding mechanism 7. The labeling mechanism 8 includes a labeling base 81 fixed on the machine base 1. A labeling lifting seat 82 is vertically and liftably installed on the labeling base 81. A vacuum suction cup 814 is installed on the labeling lifting seat 82. The bottom of the vacuum suction cup 814 is a suction plane. A number of suction holes are provided on the vacuum suction cup 814. An upper end of the vacuum suction cup 814 is provided with a suction chamber 83 communicating with the suction holes. The suction chamber 83 is communicated with a suction power device. The suction power device can be realized by using a suction fan.

[0040] A label printer 10 is fixedly installed on the machine base 1. A printing outlet of the label printer 10 faces the vacuum suction cup 814. The label printer 10 is a current conventional device and is commercially available. Labels 11 printed by the label printer 10 are supplied through the printing outlet.

[0041] A driving pulley 85 and a driven pulley 813 are rotatably installed on the labeling lifting seat 82. A number of discrete belts 86 are provided between the driving pulley 85 and the driven pulley 813. The belts 86 are connected to the printing outlet to convey the labels 11 from the printing outlet to the suction plane of the vacuum suction cup 814. A label conveying motor 84 drivingly connected to the driving pulley 85 is installed on the labeling lifting seat 82. When the labels 11 are gradually printed from the printing outlet, the labels 11 will gradually enter the suction plane. At this time, the vacuum suction force through the suction holes adsorbs the labels 11 so that they do not fall off. Then the label conveying motor 84 drives the belts 86 to convey the labels 11 to a designated area.

[0042] A blocking and positioning structure 9 is provided on the machine base 1 on the right side of the labeling mechanism 8. The labeling lifting seat 82 is driven to lift by a labeling lifting power device.

[0043] Among them, in this embodiment, the blocking and positioning structure 9 includes a positioning lifting seat 91 vertically and slidably installed on the machine base 1. A vertically arranged positioning plate 92 is provided on the positioning lifting seat 91. The positioning plate 92 extends downward above the conveyor belt 6. The labeling lifting power device drives the positioning lifting seat 91 and the labeling lifting seat 82 to lift in the same direction. The labeling lifting power device uses a servo motor and can rotate forward and backward.

[0044] A positioning and lifting seat 91 is fixed with a vertically extending positioning rack 93. The positioning rack 93 is installed on the labeling base 81 through a vertical guide rail. A labeling rack 87 parallel to the positioning rack 93 is fixed on the labeling lifting seat 82. The labeling rack 87 is installed on the labeling base 81 through a vertical guide rail. A driving gear 816 that meshes with both the labeling rack 87 and the positioning rack 93 is rotatably installed on the labeling base 81. The driving gear 816 is in transmission connection with a labeling lifting power device.

[0045] A strip-shaped hole 94 extending along the conveying direction of the conveyor belt 6 is provided on the positioning and lifting seat 91. A fastening screw is installed in the strip-shaped hole 94. The positioning and lifting seat 91 is detachably fixed to the bottom of the positioning rack 93 through the fastening screw.

[0046] The labeling lifting seat 82 is fixed to the labeling rack 87 through a vertical guide rod 89 and a connecting seat 88. The connecting seat 88 is fixed on the labeling rack 87. The vertical guide rod 89 vertically penetrates the connecting seat 88 and is sleeved with a buffer spring 810. The lower end of the vertical guide rod 89 is fixed to the labeling lifting seat 82.

[0047] A positioning device for positioning the label 11 on the suction plane is further provided on the labeling lifting seat 82. The positioning device includes a positioning block 812 provided on the labeling lifting seat 82. The positioning block 812 is located on the downstream side of the conveying of the belt 86. The positioning block 812 protrudes downward from the suction plane. When the label 11 is conveyed by the belt 86, it will be blocked by the positioning block 812 and thus reach the designated position. And the positioning block 812 protrudes downward. When labeling the label 11, the positioning block 812 will also squeeze the edge position of the decoction bag, so that the middle part of the decoction bag is fuller and thus can better fit with the label 11.

[0048] A label detection sensor 811 for detecting whether the label 11 is in place is further provided on the labeling lifting seat 82. This label detection sensor 811 can adopt a conventional photoelectric detection sensor.

[0049] A receiving groove 815 for receiving the belt 86 is further provided on the suction plane. The belt 86 is located in the receiving groove 815 and partially exposed.

[0050] The above embodiments are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and modifications made to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
