The needle bearing 368 is slidable in the sliding groove 367; the first motor 362 can drive the link 364 to rotate through the crank 363, so as to drive the first slider 32 and the second slider 33 to move towards each other. Generally, the first and second fisheye bearings 365 and 366 have the same size and the connection position with the link 364 should be on the same diameter circumference of the hinge point of the link 364 and the slider holder 361 to realize the same speed movement of the first and second sliders 32 and 33.

As mentioned above, because the weight of the Chinese medicinal granules filled in the Chinese medicinal granule packaging bag is different every time, the empty space of the bag opening before the bag is sealed is greatly changed. If the traditional Chinese medicine particles only occupy one third of the space of the medicine bag, sometimes three fourths of the space, and if a simple sealing technology is adopted in different loading proportions, the medicine bag easily contains too much air under the condition of small loading capacity, the quality guarantee period of the medicine is easily influenced, and the inflated medicine bag is easily damaged due to pressure; under the condition of large loading capacity, the traditional Chinese medicine particles easily run to the sealing position, and the sealing reliability is influenced. For this purpose, a first shaped part is also provided on the first slide 32, and a second shaped part is also provided on the second slide 33. The first shaping piece comprises a side plate 37 and a first pressing plate 38, and the side plate 37 extends out from two sides of the front surface of the first pressing plate 38; the second shaping member comprises a second pressing plate 39, and the first pressing plate 38 and the second pressing plate 39 are arranged oppositely. The side plates 37 are in contact with the two sides of the bag opening to centralize the bag opening. During the sealing process, the first pressing plate 38 and the second pressing plate 39 abut against the first heating block 34 and the second heating block 35 before; pressing out air in the packaging bag, gradually tightening the packaging bag upwards if the traditional Chinese medicine particles are already in the pressing position, and slightly pressing the traditional Chinese medicine particles downwards in the process of pressing the opening. After the sealing is completed, the first heating block 34 and the second heating block 35 are separated before the first pressing plate 38 and the second pressing plate 39, the first pressing plate 38 and the second pressing plate 39 fix the medicine bag, the medicine bag is prevented from being adhered to the first heating block 34 or the second heating block 35, and the automatic discharging is facilitated.

After the sealing is finished, the medicine bag is driven to move horizontally to the discharge hole through the displacement component 4, and automatic discharging is realized. As shown in fig. 14, the displacement assembly 4 includes a second guide rail 41, a translation slider 42, a translation fixing seat 43, and a translation slider driving mechanism 44; the second guide rail 41 is mounted on the translational fixed seat 43; the translation slider driving mechanism 44 is used for driving the translation slider 42 to move along the second guide rail 41; the translation slider 42 is connected to the slider holder 361. The translation slider driving mechanism 44 may be a cylinder capable of driving the translation slider 42 to reciprocate linearly, a linear motor, a swing link mechanism 46 driven by a motor 45, or the like.

Preferably, in order to avoid rigid collision when the first heating block 34 and the second heating block 35, and the first pressing plate 38 and the second pressing plate 39 approach each other, the first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39 are all connected with an elastic buffer mechanism (not shown in the figure). Specifically, the elastic buffer mechanism may be a spring, the first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39 are all connected to the first slider 32 or the second slider 33 through corresponding guide posts, and the spring is sleeved outside the guide posts, and the first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39, and the corresponding first slider 32 or the second slider 33 are connected through the spring, so that the first heating block 34, the second heating block 35, the first pressing plate 38, and the second pressing plate 39 have a certain buffer space when being subjected to resistance.

The working principle of the embodiment is as follows:

the bag making mechanism puts the prepared medicine bags into the fixing frame 23, the batching tray 22 rotates the position of one mounting opening, a new medicine bag is placed in the next fixing frame 23 until a preset number of medicine bags are loaded, the rotary table rotating mechanism 11 drives the rotary table 2 to rotate until the batching tray 22 loaded with the medicine bags is positioned below the blanking mechanism 100, the blanking mechanism 100 has an automatic quantitative blanking function, medicine materials with preset weight can be injected into the medicine bags, after blanking of one medicine bag is completed, the batching tray rotating mechanism 21 drives the batching tray 22 to rotate the position of one mounting opening 24, blanking is carried out on the next medicine bag until the preset number of medicine bags are loaded.

After the medicine bags are filled with traditional Chinese medicine particles, the rotary table rotating mechanism 11 drives the rotary table 2 to rotate again, the medicine bags needing sealing at present are conveyed to the position right above the jacking component 5 by matching with the rotation of the dispensing disc 22, and the jacking component 5 and the sealing component 3 are opposite up and down. At this time, the lifting assembly 5 drives the lifting block 51 to rise, the latter pushes the bottom of the medicine bag through the bayonet 511 to lift the medicine bag out of the fixing frame 23, and the positioning cavity 23b of the fixing frame 23 continuously guides the medicine bag during the lifting process until the medicine bag is lifted to the preset position of the sealing assembly 3. Subsequently, the slider driving mechanism 36 drives the first slider 32 and the second slider 33 to move toward each other, and starts the sealing operation. In the sealing process, the side plate 37 firstly contacts with the medicine bag, lightly contacts with the two sides of the medicine bag to prevent the medicine bag from inclining, then the first compression plate 38 and the second compression plate 39 start to contact with the central height position of the medicine bag and gradually compress the medicine bag towards each other, if the compression position is filled with traditional Chinese medicine particles, because the first compression plate 38 and the second compression plate 39 both have elastic margins, the compression surfaces of the first compression plate 38 and the second compression plate 39 incline slightly, the medicine bag forms a shape that the center bulges and is gradually attached from the center to the opening position; finally, the first heating block 34 and the second heating block 35 compress and heat a predetermined sealing position near the opening of the medicine bag to perform sealing operation. After sealing, displacement assembly 4 drives the whole translation of seal assembly 3, drives the medicine bag and moves to ejection of compact station, and first slider 32 keeps away from each other with second slider 33 after that, and first heating block 34 and second heating block 35 are separated with the medicine bag earlier, and first pressure strip 38 and second pressure strip 39 and medicine bag separation after that, the medicine bag falls into ejection of compact station because of the action of gravity. The discharging station can be a simple discharging port, and an operator manually takes the sealed medicine bag from the discharging port; the medicine bag sealing device can also be a discharging transmission line, the medicine bag after sealing is conveyed to a preset temporary storage position through the discharging transmission line, and discharging is carried out after all packaging is finished.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
