[0038] It is worth noting that in the present application, the hot melt sealing machine 6 is a hot melt sealing machine commonly used in the existing market. When the two hot melt sealing machines 6 on the left and right sides are connected, the top end ports of the packaging bag 25 between the two hot melt sealing machines 6 can be hot-melt sealed.

When the output end is stopped, it can self-lock and will not rotate under external force. The motor 11 is a forward and reverse motor commonly used in the market, and its output end can rotate forward or reverse according to usage requirements. A relay commonly used in the existing market is provided in the present application, and the above-mentioned relay is used to realize the reciprocating rotation of the output end of the motor 11 for continuous forward and reverse conversion, which can The screw 10 is a self-locking screw 10 available in the existing market, which can achieve self-locking when it stops rotating and will not rotate due to external forces. The filling machine 23 adopts a filling machine commonly used on the market for filling soup bags, and the valve 24 is a valve body commonly used on the market for controlling whether the fluid passes through. In the present application, the valve 24 is connected to a commonly used controller on the market, and the controller controls the valve 24 to be opened intermittently to realize the filling of multiple packaging bags 25 one by one. The model of the valve 24 is not limited here, and it can meet the filling requirements of the soup. The forward and reverse rotation frequency of the motor 11 and the opening and closing frequency of the valve 24 are set according to actual production needs. The model of the above-mentioned existing components is not limited here or described in too much detail.

[0039] The working principle of a soup bag filling machine in this embodiment is as follows:

[0040] The packaging bag 25 is placed in the placement groove 4 at the supporting seat 3. The packaging bag 25 is stably placed and will not fall over under the action of the left and right side walls of the placement groove 4. The forward-rotating motor 11 is turned on to drive the lead screw 10 to rotate, so as to prompt the two first fixed blocks 8 respectively threaded on both sides of the lead screw 10 to move synchronously away from each other, so as to prompt the mounting plate 7 on the left and the first movable arm 5 on the right to move away from each other, that is, to prompt the two first movable arms 5 to move synchronously away from each other. At this time, the two hot-melt sealing machines 6 gradually move away from each other. At the same time, the two first movable arms 5 moving outward respectively prompt the driving plates 15 and the limiting grooves 16 at the corresponding positions to move outward synchronously, so as to prompt the two fixing pins 17 to be forced to move toward the middle along the inner cavities of the limiting grooves 16 at the corresponding positions, so as to drive the two second movable arms 18 to gradually approach each other. At this time, the two driving blocks 19 at the ends of the two second movable arms 18 gradually approach each other and gradually apply a driving force to the front and rear side walls of the packaging bag 25. , prompting the top end port of the packaging bag 25 to be forced to open; at this time, after the soup in the filler 23 is properly filled into the packaging bag 25 through the opened valve 24, the valve 24 is closed; at this time, the motor 11 rotates in the opposite direction to prompt the two first fixed blocks 8 on the screw 10 to gradually approach, that is, to prompt the mounting plate 7 on the left and the first movable arm 5 on the right to gradually approach, driving the left and right first movable arms 5 to approach synchronously, at this time, the two hot melt sealers 6 at the ends of the two first movable arms 5 gradually approach to fit and dock to perform hot melt sealing on the top end port of the packaging bag 25, at the same time, when the two first movable arms 5 approach synchronously in the horizontal direction, the two driving plates 15 are prompted to respectively drive the two fixed pins 17 to respectively drive the second movable arms 18 at the corresponding positions to move outwards, that is, to realize that the two driving blocks 19 at the ends of the two second movable arms 18 are gradually separated, ensuring that the two hot melt sealers 6 will not be interfered by the two driving blocks 19 when docking the hot melt processing;

[0041] The present application can ensure that the device realizes that the front and rear driving blocks 19 are close to the middle while the two hot melt sealers 6 are separated from each other, and the top end of the packaging bag 25 is squeezed to deform and open. After the packaging bag 25 is filled with soup, the two hot melt sealers 6 are close to the middle to seal the top end of the packaging bag 25, and the two driving blocks 19 are separated from each other, providing sufficient space for the two hot melt sealers 6 to dock.

[0042] The utility model causes the top end of the packaging bag 25 to open by means of two driving blocks 19 that move synchronously toward the middle, thereby ensuring that the soup in the filling machine 23 is smoothly filled into the inner cavity of the packaging bag 25 through the valve 24 in the open state. Compared with the traditional method that lacks the function of driving the packaging bag 25 to open, the utility model is more conducive to the rapid filling of the soup. When the two groups of driving blocks 19 move away from each other, the two groups of hot-melt sealing machines 6 are caused to move closer to each other, so as to realize the automatic sealing of the top end of the packaging bag 25 by the two hot-melt sealing machines 6 after filling. The operator no longer needs to set a separate driving instruction for the sealing step or operate additional equipment, thereby simplifying the entire filling and sealing operation process, reducing the pause time caused by complex operations, and making the production process smoother.

[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
