[0055] For reference Figure 1 and Figure 6 The upper film station 1 comprises a film feeding roller, a guide roller 102 and a buffer roller 103.

[0056] The film feeding roller is rotatably arranged, and a film roll 101 is sleeved on the film feeding roller.

[0057] The guide roller 102 and the buffer roller 103 are used for guiding and conveying the film material, and the guide roller 102 and the buffer roller 103 are located at different heights, and the vertical distance and the horizontal distance between the guide roller 102 and the buffer roller 103 are kept at a predetermined value.

[0059] In this way, by increasing the horizontal and vertical distances between the guide roller 102 and the buffer roller 103 within a reasonable range, the storage amount of the film between the guide roller 102 and the buffer roller 103 is increased, and more operating time is provided for the operator to replace the film roll 101, so that the film roll 101 can be replaced without stopping the equipment, and the production efficiency is improved.

[0060] Please refer to Figure 1 and Figure 6 The film feeding platform 104 is fixedly arranged between the film feeding roller and the guide roller 102, and is used for the operator to cut and fix the film material.

[0061] When replacing the film, the operator can operate through the film replacement platform 104 to complete the film cutting and fixing operation, reduce the operation difficulty, and make the film replacement operation more convenient.

[0062] Please refer to Figure 1 The bag making mechanism further comprises an upper hose station 5, a hose preheating station 6, a hose heat sealing station 7, a shaping station 8, and a weak welding station 9.

[0063] The upper hose station 5 is used to provide a hose, and a hose clamp is used to place and fix a hose with a fixed length. This station can use a segmented hose cut to size, or use a roll of hose and be equipped with a cutting assembly to cut the hose to the required fixed length.

[0064] The hose preheating station 6 is arranged on one side of the upper hose station 5, and is used to preheat the welding position of the hose to ensure the welding effect between the hose and the soft bag.

[0065] The hose heat sealing station 7 is arranged on one side of the hose preheating station 6, and is provided with a mold for heating and welding.

[0066] The shaping station 8 is arranged on one side of the peripheral heat sealing station 4, and is mainly used for cooling and shaping the welding position of the hose by the cylinder driven mold, and removing the waste edges and corners around the soft bag to ensure the welding quality of the soft bag and the hose.

[0067] The weak welding station 9 is used for processing the to-be-filled piece into a double-chamber or multi-chamber piece. The weak welding station 9 mainly acts by driving the heated mold to weld the film material and the hose by maintaining a certain pressure and gap. Specifically, the hose is placed between the two layers of the film of the soft bag to perform the welding operation at the connection position. When the welding is performed once, the to-be-filled piece is processed into two chambers. When the welding is performed multiple times, the to-be-filled piece is processed into a soft bag with multiple chambers.

[0068] Please refer to Figure 1 、 Figures 7 to 8 The upper hose station 5 is provided with an upper hose device. The upper hose device comprises a support 501, a rotating shaft 502 arranged on the support 501, and a supporting piece 503. The supporting piece 503 is sleeved on the rotating shaft 502. The support 501 is further provided with a driving device for driving the rotating shaft 502 to rotate. The driving device comprises a driving motor 504, a transmission chain 505, and a transmission sprocket 506. The driving motor 504 drives the rotating shaft 502 to rotate through the transmission sprocket 506 and the transmission chain 505.

The driving sprocket is sleeved on the output shaft of the driving motor 504, and the driven sprocket is sleeved on the rotating shaft 502. The transmission chain 505 is engaged between the driving sprocket and the driven sprocket. When the driving motor 504 works, the driving sprocket drives the driven sprocket to rotate through the transmission chain 505, thereby driving the rotating shaft 502 to rotate and unwinding the hose roll arranged on the supporting piece 503.

[0070] In this way, the driving motor 504 provides tension to drive the hose roll to rotate and achieve unwinding, avoiding the situation that the length of the hose is insufficient due to insufficient tension. Moreover, the length of the unwound hose can be adjusted each time by controlling the driving motor 504, thereby ensuring the use requirement.

[0071] Please refer to Figure 1 The bag transfer station 10 is arranged at the rear end of the weak welding station 9, and is used for transferring the to-be-filled piece to the filling mechanism through the bag transfer station 10.

[0072] The bag transfer station 10 is located between the weak welding station 9 and the nitrogen filling station 15 in the filling mechanism. After the soft bag is made in the weak welding station 9, the soft bag is transferred to the filling mechanism through the bag transfer station 10, so as to perform the subsequent filling and nitrogen filling operations simultaneously.

[0073] Please refer to Figure 1 The filling mechanism further comprises a plug feeding station 12, a plug feeding station 14, and a bag output station 13.

[0074] The capping station 12 is arranged at the rear end of the filling station 11, and is used for filling the sealing plug to the filled and sealed piece.

[0075] The plug feeding station 14 is arranged at one side of the capping station 12, and is used for feeding the sealing plug to the capping station 12.

[0076] The bag output station 13 is arranged at the rear end of the capping station 12, and is used for receiving and outputting the filled and capped piece.

[0077] The operation process of the multi-chamber soft bag making and sealing machine is as follows:

[0078] Film feeding station 1-printing station 2-film pulling station 3-peripheral heat sealing station 4-soft tube heat sealing station 7-shaping station 8-weak welding station 9-bag transfer station 10-nitrogen filling station 15-filling station 11-capping station 12-bag output station 13. The bag transfer station 10, the filling station 11, the capping station 12 and the bag output station 13 are arranged as a group, and under the premise of meeting the production speed requirement, the filling and sealing conveying overall length of the bag making and sealing machine is greatly shortened, the equipment floor area is reduced, and the equipment cost is reduced.

[0079] The multi-chamber soft bag making and sealing machine provided by the utility model can reduce the system circulation time and improve the production efficiency compared with the filling and nitrogen filling being performed separately, the nitrogen filling station 15 is provided with an exhaust device 151, the nitrogen concentration is monitored in real time by a pressure sensor and a flow meter, and the nitrogen filling flow rate and the exhaust frequency are dynamically adjusted, the residual oxygen amount is kept stable, the residual oxygen control precision is improved, and higher requirements can be met.
