Among them, the film feeding unit 2 provides packaging film to the bag guide 4, and the film feeding unit 2 includes a support roller 2-1, a transition roller 2-2 and a tension roller 2-3. The support roller 2-1 is detachably mounted on the frame 1, the transition roller 2-2 is rotatably mounted on the frame 1, and the tension roller 2-3 is swingably mounted on the frame 1 through a rotating arm. Such a setting can make the feeding of the packaging film smoother and is also conducive to the winding and forming of the packaging film in the bag guide 4.

[0037] In this embodiment, the upper end of the bag guide 4 is set as a C-shaped opening 4-1, the middle and lower part of the bag guide 4 is a cylindrical shape 4-2, the C-shaped opening 4-1 gradually shrinks toward the middle and lower part, and the middle and lower part of the bag guide 4 is provided with a slit opening 4-3 below the C-shaped opening 4-1. In this way, the sheet-like packaging film can be gradually rolled into a cylindrical shape, which is conducive to sealing the Chinese medicine material inside after the side sealing and the transverse sealing, and the packaging effect is better. The high effect also reduces the defective rate during film bag packaging. At the same time, the feeding device 3 conveys the material into the C-shaped opening 4-1 to realize automatic loading and packaging.

[0038] The rolling side sealing unit 5 of this embodiment includes a pair of rotating wheels 5-1 and a rotating driving device 5-4. The pair of rotating wheels 5-1 are driven to rotate by the rotating driving device 5-4. According to the needs, one or a pair of rotating wheels 5-1 are provided with a heating plate 5-2 along the circumferential direction. The heating plate 5-2 is connected to the power supply. The pair of rotating wheels 5-1 is located below the bag guide 4. In this way, the independent vertical heating sealing device of the prior art can be omitted, and the rolling bag pulling and heat sealing are combined together, which has a simple structure and high working efficiency. The rotating driving device 5-4 is a motor.

[0039] The transverse sealing and cutting unit 6 of this embodiment is located below a pair of rotating wheels 5-1 and heat-seals and cuts the packaging film transversely. Specifically, the transverse sealing and cutting unit 6 includes a pair of heat-sealing plates 6-1 and a transverse driving device 6-3 arranged opposite to each other.

The transverse driving device 6-3 of this embodiment is a cylinder or a device that can drive the heat-sealing plate 6-1 to move horizontally. Example 2

[0040] The main technical scheme of this embodiment is basically the same as that of Embodiment 1. For the features not explained in this embodiment, the explanation in Embodiment 1 is adopted and will not be repeated here. In this embodiment, a heating plate 5-2 is provided on the surface of one of the pair of rotating wheels 5-1. The heating plate 5-2 is in contact with a conductive column 5-3. The conductive column 5-3 is connected to a power source. The contact conduction can save the wires from being entangled. The surface of the other rotating wheel 5-1 is provided with a high-temperature resistant rubber sleeve and this rotating wheel 5-1 is driven to rotate by a rotating drive device 5-4 as a driving wheel. This is beneficial to increase the friction between the rotating wheel 5-1 and the packaging film, which is more conducive to pulling down the packaging film / packaging bag. The rotating drive device 5-4 of this embodiment is a motor.
