[0008] A feeding mechanism, wherein the feeding mechanism is installed on the processing table, the output end of the feeding mechanism is located at one side of the storage box, and the feeding mechanism is used to transport the packaging bags in the storage box to one end of the feeding mechanism;

Initially, the angle between the movable baffle and the fixed baffle is an acute angle. In order to make the packaging bag in the storage box discharge smoothly, when the fixed baffle is located on one side of the storage box, the movable baffle needs to contact the surface of the packaging bag to avoid bending of the packaging bag and causing multiple packaging bags to be transported out at one time. A limiting frame is fixedly connected to the top of the storage box, and the cross-section of the limiting frame is It is L-shaped.

At this time, the fixed baffle is moved, so that the fixed baffle can drive the outermost packaging bag to discharge. Due to the obstruction of the side wall of the material storage box and the small friction between the packaging bags, the packaging bag in contact with the outermost packaging bag will not be moved out, so that the packaging bags can be loaded one by one.

[0014] In order to prevent the packaging bag from being deformed by suction, a pad is arranged inside the suction port, with a gap between the pad and the suction port. The pad supports most of the surface of the packaging bag to prevent the packaging bag from being deformed.

[0022] Further technical solution: the vacuum assembly includes a third mounting frame fixedly connected to the processing table, the third mounting frame is fixedly connected to a third telescopic rod, the movable end of the third telescopic rod is fixedly installed with a third vacuum pump, the output end of the third vacuum pump is connected to a third air duct, when in use, the third air duct is inserted into the packaging bag, the third vacuum pump is started, and the third vacuum pump extracts air in the packaging bag through the third air duct, thereby reducing the oxygen content in the packaging bag, reducing the activity of microorganisms, and extending the shelf life of Chinese medicinal materials;

[0023] During vacuuming, in order to improve the sealing between the packaging bag and the third air duct, and thus improve the efficiency of vacuuming, notches matching the third air duct are provided on the opposite sides of the two adsorption boxes.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention is provided with an automatic feeding mechanism, a feeding mechanism, a quantitative loading mechanism, a heat sealing mechanism, a transport mechanism and a horizontal conveyor. The automatic feeding mechanism transports the packaging bag to the feeding mechanism. The transport mechanism transports the packaging bag at the feeding mechanism to the bottom of the quantitative loading mechanism. The quantitative loading mechanism loads a certain amount of Chinese medicinal materials into the packaging bag. The horizontal conveyor and the transport mechanism work together to transport the filled packaging bag to the heat sealing mechanism. The heat sealing mechanism heat-seals the packaging bag. Then the transport mechanism releases the packaging bag. The packaging bag is unloaded with the horizontal conveyor.

[0027] 2. During feeding, the present invention sets a movable baffle and sets a torsion spring between the movable baffle and the fixed baffle.

Then, the fixed baffle inserts one side of the packaging bag into the feeding mechanism, and the fixed baffle releases the adsorption of the packaging bag. The feeding mechanism can smoothly receive the packaging bag and drive the packaging bag to move.

[0028] 3. The present invention sets a limit frame and makes the cross section of the limit frame L-shaped. When the movable baffle moves to one side of the storage box, the limit frame squeezes the movable baffle, so that the surfaces of the movable baffle and the fixed baffle are parallel, and the packaging bag contacts the surface of the movable baffle, so as to avoid the packaging bag being bent by pressure and causing the fixed baffle to transport multiple packaging bags at one time. When the movable baffle moves out of the range of the limit frame, under the action of the torsion spring, the movable baffle rotates outward and leaves the surface of the packaging bag, so as to avoid the movable baffle affecting the movement of the packaging bag;

[0029] 4. The present invention provides a storage bin and a quantitative discharging valve. When the packaging bag moves to the bottom of the storage bin, the quantitative discharging valve fills a quantitative amount of Chinese medicinal materials into the packaging bag, without the need for manual weighing, and the quantitative measurement is more accurate.

[0030] 5. The present invention provides a vacuum pumping component, which performs a vacuum pumping operation on the packaging bag before the packaging bag is sealed, thereby removing the air inside the packaging bag and extending the shelf life of the Chinese medicinal materials;

[0031] 6. The present invention provides a notch on the adsorption box. After the third air duct is inserted into the packaging bag, the two adsorption boxes clamp the packaging bag, and the third air duct is just located in the notch of the two adsorption boxes. The two adsorption boxes and the third air duct seal the opening of the packaging bag, so that the third air duct can only extract the air in the packaging bag, thereby improving the vacuuming efficiency;

[0032] 7. The present invention provides two edge-sealing rods, a groove, a first compression spring, a movable sealing block, a sealing plate and a storage groove. When the third air duct is not inserted into the notch, the movable sealing block will seal the notch to prevent the notch from affecting the adsorption force of the adsorption box on the packaging bag. When the third air duct is inserted into the notch, the movable sealing block is squeezed by the third air duct and then moves outward, which does not affect the sealing of the adsorption box on the packaging bag, thereby improving the vacuuming efficiency.

In order to enable the adsorption box 55 to smoothly clamp the packaging bag, the bottom of the adsorption box 55 is higher than the top of the first feeding roller group 43 and the second feeding roller group 44, and not lower than the top of the heat sealing knife 61.

[0061] In order to drive the U-shaped frame 59 to move, a second mounting frame 510 is fixedly connected to the bottom of the processing table 1, and a third servo motor 511 is fixedly installed on the second mounting frame 510.

The second screw 512 is threadedly connected to the U-shaped frame 59, and the second screw 512 is rotatably connected to the processing table 1.

[0062] When the packaging bag is transferred, the third servo motor 511 drives the second screw 512 to rotate, the second screw 512 drives the U-shaped frame 59 to move, the U-shaped frame 59 drives the mounting plate 58, the fixing column 57, the first telescopic rod 56 and the adsorption box 55 to move, and the two adsorption boxes 55 are moved to the two sides of the packaging bag at one end of the feeding mechanism 4, the first telescopic rod 56 drives the adsorption box 55 to move, the two adsorption boxes 55 clamp the packaging bag, and then the adsorption box 55 drives the packaging bag to move to the bottom of the discharge port of the storage bin 91, and then the second vacuum pump 51 is started, and the second vacuum pump 51 extracts the air inside the adsorption box 55 through the second air duct 52, and under the effect of atmospheric pressure, the air inside the adsorption box 55 is sucked out. The two sides of the packaging bag are adsorbed onto the two adsorption boxes 55, and then the first telescopic rod 56 drives the adsorption box 55 to move in the opposite direction, and the two adsorption boxes 55 open the opening of the packaging bag, and then the quantitative discharge valve 93 quantitatively discharges the Chinese medicinal materials in the storage bin 91, so that the Chinese medicinal materials fall into the packaging bag, and then the first telescopic rod 56 drives the adsorption box 55 to move in the opposite direction again, so that the two adsorption boxes 55 seal the opening of the packaging bag, and at the same time, the horizontal conveyor 7 and the third servo motor 511 are started, so that the horizontal conveyor 7 and the third servo motor 511 jointly drive the packaging bag to move between the two heat sealing knives 61, and the two heat sealing knives 61 seal the packaging bag;

[0063] Then the two first telescopic rods 56 drive the two suction boxes 55 to release the packaging bags, and the sealed packaging bags are unloaded along the horizontal conveyor 7, and the suction box 55 moves to one end of the feeding mechanism 4 again and transfers the next empty packaging bag. This cycle can realize the filling, packaging and unloading of Chinese medicinal materials.

[0064] like Figure 1-Figure 2 and Figure 4 As shown, an automatic packaging production line for Chinese medicinal materials provided by the present invention is provided. In order to extend the shelf life of Chinese medicinal materials, the packaging bags are usually vacuumed. Therefore, in this embodiment, a vacuuming component 8 is also provided. The vacuuming component 8 is installed on the processing table 1. The output end of the vacuuming component 8 is located above the heat sealing knife 61. The vacuuming component 8 is used to extract the air in the packaging bag.

[0065] like Figure 1-Figure 2 and Figure 4As shown, an automatic packaging production line for Chinese medicinal materials provided by the present invention is provided. In this embodiment, the vacuum assembly 8 includes a third mounting frame 84 fixedly connected to the processing table 1, and a third telescopic rod 83 is fixedly connected to the third mounting frame 84. A third vacuum pump 82 is fixedly installed at the movable end of the third telescopic rod 83. The output end of the third vacuum pump 82 is connected to a third air duct 81. When in use, the third air duct 81 is inserted into the packaging bag, and the third vacuum pump 82 is started. The third vacuum pump 82 extracts air in the packaging bag through the third air duct 81, thereby reducing the oxygen content in the packaging bag, reducing the activity of microorganisms, and extending the shelf life of the Chinese medicinal materials.

[0066] During vacuuming, in order to improve the sealing between the packaging bag and the third air duct 81, and thus improve the efficiency of vacuuming, notches matching the third air duct 81 are provided on the opposite sides of the two adsorption boxes 55. When the adsorption box 55 moves the packaging bag to the bottom of the third vacuum pump 82, the notches are located exactly below the third air duct 81. After the third air duct 81 is inserted into the packaging bag, the two adsorption boxes 55 clamp the packaging bag, and the third air duct 81 is located exactly in the notches of the two adsorption boxes 55. The two adsorption boxes 55 and the third air duct 81 seal the opening of the packaging bag, so that the third air duct 81 can only extract the air in the packaging bag, thereby improving the efficiency of vacuuming.

[0067] When the third air duct 81 is not inserted into the notch, the adsorption box 55 will be connected to the outside through the notch, thereby affecting the adsorption force of the adsorption box 55 on the packaging bag. Based on this, the present invention further provides two edge sealing rods 515, and grooves 517 are provided on both sides of the notch. The two edge sealing rods 515 are respectively slidably connected to the inside of the two grooves 517, and a first compression spring 516 is connected between the edge sealing rod 515 and the groove 517. A movable sealing block 53 is fixedly connected between the two edge sealing rods 515, and a sealing plate 54 is fixedly connected to the side wall of the notch. A receiving groove 514 adapted to the sealing plate 54 is provided on the side of the movable sealing block 53. Initially, one end of the sealing plate 54 is located inside the receiving groove 514. In order to avoid air leakage, the thickness of the sealing plate 54 is less than the thickness of the edge sealing rod 515.

The material roller group 44 rotates synchronously and in opposite directions, the first feeding roller group 43 and the second feeding roller group 44 cooperate to transport the packaging bag to one end close to the quantitative loading mechanism 9, and then the third servo motor 511 drives the two adsorption boxes 55 to move to both sides of the packaging bag, the first telescopic rod 56 drives the adsorption boxes 55 to clamp both sides of the packaging bag, and then the adsorption box 55 drives the packaging bag to move to the bottom of the storage bin 91, under the action of the second vacuum pump 51, the adsorption box 55 adsorbs the two sides of the packaging bag, and then the first telescopic rod 56 drives the adsorption box 55 to move outward, the two adsorption boxes 55 pull the packaging bag apart, and the quantitative discharge valve 93 discharges the bag to the bag. A certain amount of Chinese medicinal materials are discharged from the bag, and then the horizontal conveyor 7 and the adsorption box 55 drive the packaging bag to move to the bottom of the third air duct 81, and the third telescopic rod 83 drives the third air duct 81 to be inserted into the packaging bag, and then the first telescopic rod 56 drives the adsorption box 55 again to clamp the packaging bag, and the third air duct 81 is stuck in the notch, and the movable sealing block 53 is squeezed open by the third air duct 81, and the third vacuum pump 82 extracts the air in the packaging bag through the third air duct 81, and then the third telescopic rod 83 drives the third air duct 81 to be quickly pulled out of the packaging bag, and under the action of the first compression spring 516, the movable sealing block 53 closes the notch to prevent outside The external air enters the packaging bag again, and then the heating block 64 heats the heat sealing knife 61, and the second telescopic rod 63 drives the heat sealing knife 61 to squeeze the packaging bag and enter the opening of the packaging bag to perform heat sealing, and then the second telescopic rod 63 drives the heat sealing knife 61 to release the packaging bag, and the first telescopic rod 56 drives the adsorption box 55 to release the packaging bag, and the packaging bag will be dumped onto the horizontal conveyor 7, and the horizontal conveyor 7 drives the packaging bag to unload, and then the adsorption box 55 returns to one end of the feeding mechanism 4 and continues to transport the packaging bag.
