The free ends of the first and second sub-brackets 121, 122 are arranged to be separable and foldable. When the free ends of the first and second sub-brackets 121 and 122 are folded, a barrel-shaped accommodating space is formed with the main bracket 110 and the bottom plate 130. The folded film 801 can enter the bag holder 100 from the side, and has the advantages of simple structure, convenience in operation and small occupied space.

Two first elastic members 151 are provided at the hinge joint of the main bracket 110 and the first sub-bracket 121, and two second elastic members 152 are provided at the hinge joint of the main bracket 110 and the second sub-bracket 122. In the present embodiment, the first elastic member 151 and the second elastic member 152 are both torsion springs. The first elastic member 151 is provided to bias the first sub-holder 121 in the second sub-holder direction, and the second elastic member is provided to bias the second sub-holder 122 in the first sub-holder 121 direction. The default state of the first elastic member 151 and the second elastic member 152 is to bring the first sub-bracket 121 and the free end of the second sub-bracket 122 together.

The bracing mechanism 140 may drive the free ends of the first and second sub-brackets 121, 122 away. The bracing mechanism 140 includes a bracing bar 142 and a bracing head 141 provided at a front end of the bracing bar. The stay bar 142 is disposed under the base plate 130 and slidably coupled to the base plate 130.

Thereby, the shape of the upper end opening of the bag 801 can be better maintained. In other embodiments, the cross-section of the first and second sub-brackets 121, 122 may also be planar.

Referring to fig. 7, in the present embodiment, the bottom plate 130 has a V-shaped longitudinal section. Thereby, the position of the bottom edge of the bag can be better defined. In other embodiments, the longitudinal cross-section of the bottom 130 may also be flat or curved.

To use the bag holder 100, the stay 142 is pushed by an external force, the support head 141 is moved forward, the pulley 143 contacts the free ends of the first and second sub-frames 121 and 122, the free ends of the first and second sub-frames 121 and 122 are pushed apart, the 801 folding film 800 is inserted into the bag holder from between the free ends of the first and second sub-frames 121 and 122, the front side of the 801 folding film 800 contacts the main frame 110, and the bottom of the 801 folding film 800 contacts the bottom plate. At this time, the external force is released, and the free ends of the first sub-holder 121 and the second sub-holder 122 are closed by the first elastic member 151 and the second elastic member 152, so that the bag 801 is always kept in an upright state.

Referring to fig. 13, the left clamp plate 331 and the right clamp plate 332 of the banding mechanism 330 are separated, and the bracing mechanism drives the free ends of the first and second sub-brackets 121, 122 of the bag holder 100 away. The unwinding shaft 392 unwinds, and the film pushing driving mechanism 322 drives the film pushing member 321 to move forward, and the front end of the film pushing member 321 moves forward against the front end of the double-folded film 800 which is heat-sealed, and enters the bag holder 100 until the front end of the double-folded film 800 abuts against the main support 110 of the bag holder 100.

The left-hand member 221 of the mouth holding mechanism 200 is rotated downward and outward, and the left side of the folded film in the bag holder 100 is held from the inside; the right turner 222 is rotated downward and outward to brace the right side of the folded film inside the bag holder 100 from the inside.

Referring to fig. 14, the film pushing driving mechanism 322 drives the film pushing member 321 to move backward, and the film separating member 312 at the rear end of the film pushing member 321 separates two sides of the folded film at the rear side at the same time. The free ends of the first 121 and second 122 sub-brackets of the bag holder 100 are closed simultaneously.

The sealing drive mechanism 333 drives the left clamp plate 331 and the right clamp plate 332 to close, and the portion of the folded film 800 sandwiched between the left clamp plate 331 and the right clamp plate 332 is heat sealed. The slitting driving mechanism 342 simultaneously drives the cutter 341 to move along the cutter holes, and the bag 801 with the sealed edges at two sides and the folded film 800 with the sealed edges at the front end are slit.

The left-hand member 221 of the mouth keeping mechanism 200 rotates upward and inward, and the right-hand member 222 rotates upward and inward, returning to the initial horizontal position. The upper end opening of the bag 801 is kept open due to the setting action of the bag holder 100.

After the cutting operation is completed, the carousel 400 moves the bag holder 100 to the filling station of the next process, and the granular formulation may fall directly into the bag 801 from the opening at the upper end of the bag.

By repeating the steps, bag making and bag feeding operations of the bags can be completed at one time, the working efficiency is high, and cross contamination can be avoided.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
