Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The present invention provides a multi-chamber soft bag making and filling machine. By setting a separate nitrogen filling station 15, nitrogen filling and filling are carried out simultaneously, which reduces the system cycle time and improves production efficiency. The pressure sensor and the flow meter monitor the nitrogen concentration in real time and dynamically adjust the nitrogen filling flow rate and the exhaust frequency, thereby improving the residual oxygen control accuracy and meeting higher requirements.

[0044] Please refer to Figures 1 to 8 The multi-chamber soft bag making and filling machine provided by the present invention includes a frame 16, a bag making mechanism and a filling mechanism.

[0045] The specific structural form of the frame 16 can be specifically set in combination with the size and position of the installed components to ensure sufficient strength and hardness.

[0046] The bag making mechanism is arranged on the frame 16 and is used to form the parts to be filled.

[0047] The filling mechanism is arranged on the frame 16, and is used for filling and plugging the parts to be filled and then outputting them. The filling mechanism includes a nitrogen filling station 15 and a filling station 11. The filling station 11 is used to fill the parts to be filled, and the nitrogen filling station 15 is used to fill the parts to be filled with nitrogen, wherein the filling operation and the nitrogen filling operation are carried out simultaneously; the nitrogen filling station 15 is also provided with an exhaust device 151, and the exhaust device 151 monitors the nitrogen concentration in real time through a pressure sensor and a flow meter and dynamically adjusts the nitrogen filling flow rate and the exhaust frequency.

[0048] The multi-chamber soft bag making and filling machine provided by the present invention is provided with a separate nitrogen filling station 15, and nitrogen filling and filling are carried out simultaneously. Compared with filling and nitrogen filling being carried out separately, the system cycle time can be reduced and the production efficiency can be improved; the nitrogen filling station 15 is added with an exhaust device 151, which monitors the nitrogen concentration in real time through a pressure sensor and a flow meter and dynamically adjusts the nitrogen filling flow rate and the exhaust frequency, thereby improving the residual oxygen control accuracy, and the residual oxygen content can be stably ≤0.5%, meeting higher requirements.

[0049] Please refer to Figure 1 , Figures 4 to 5The bag making mechanism includes a film-applying station 1, a printing station 2, a film-drawing station 3 and a peripheral heat-sealing station 4 which are arranged in sequence along the operation order. The film-applying station 1 is used to unfilm the entire roll of film material to supply it to the subsequent stations. The printing station 2 is used to print the film material. The film-drawing station 3 is used to pull the printed film material to realize the feeding of the film material. The peripheral heat-sealing station 4 includes an upper mold 401 and a lower mold 402 arranged opposite thereto. The upper mold 401 and the lower mold 402 can be relatively close to each other so that the periphery of the film material is uniformly stressed and then welded to form a soft bag. A first cylinder 403 arranged in the horizontal direction is provided on one side of the upper mold 401 / lower mold 402. The first cylinder 403 is connected to a connecting rod mechanism 404. The first cylinder 403 drives the upper mold 401 / lower mold 402 to move up and down through the connecting rod mechanism 404.

[0050] The first cylinder 403 outputs horizontal movement, and the connecting rod mechanism 404 is used to convert the horizontal movement into vertical lifting movement of the upper mold 401 or the lower mold 402. This arrangement can save space in the vertical direction at the bottom of the equipment and is suitable for occasions with high requirements on installation space.

[0051] Optionally, in one specific embodiment, the connecting rod mechanism 404 includes a connecting rod and a slider, the connecting rod and the slider are respectively arranged on the first cylinder 403 and the upper mold 401 / lower mold 402, and the connecting rod is connected to the slider through a revolute pair.

[0052] During operation, the first cylinder 403 outputs horizontal movement, so that the connecting rod drives the slider to move in the vertical direction through the rotating pair, thereby driving the upper mold 401 or the lower mold 402 to rise and fall. The upper mold 401 and the lower mold 402 are relatively close to each other, so that the periphery of the film material is evenly stressed and then welded to form a soft bag.

[0053] Optionally, in another specific embodiment, the connecting rod mechanism 404 includes a rack, a gear, a connecting rod and a slider, the rack is horizontally arranged on the first cylinder 403, the slider is arranged on the upper mold 401 / lower mold 402, the gear is meshingly connected to the rack, and the connecting rod is respectively connected to the gear shaft and the slider of the gear.

[0054] During operation, the first cylinder 403 drives the rack to move in the horizontal direction, and the gear rotates to drive the connecting rod to swing, thereby driving the slider to move in the vertical direction, thereby driving the upper mold 401 or the lower mold 402 to rise and fall. The upper mold 401 and the lower mold 402 are relatively close to each other so that the periphery of the film material is evenly stressed and then welded to form a soft bag.

[0055] Please refer to Figure 1 and Figure 6 The film loading station 1 includes a film feeding roller, a guide roller 102 and a buffer roller 103 .

[0056] The film delivery roller is rotatably arranged, and a film roll 101 is sleeved on the film delivery roller, and the film delivery roller can be driven to rotate by a motor.

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

[0058] The predetermined value of the horizontal distance between the guide roller 102 and the buffer roller 103 is 1 m to 1.2 m, and the predetermined value of the vertical distance between the guide roller 102 and the buffer roller 103 is 2 m to 6 m.

[0059] Such arrangement increases the lateral and longitudinal spacing between the guide roller 102 and the buffer roller 103 as much as possible within a reasonable range, thereby increasing the film storage capacity between the guide roller 102 and the buffer roller 103, providing the operator with more operating time to replace the film roll 101, thereby achieving replacement of the film roll 101 without stopping the equipment, thereby improving production efficiency.

[0060] Please refer to Figure 1 and Figure 6 The film loading station 1 further includes a film changing platform 104, which is fixedly arranged and located between the film feeding roller and the guide roller 102, for operators to cut and fix the film material.

[0061] When changing the membrane, the operator can work through the membrane changing platform 104 to complete the operations of cutting the membrane and fixing the membrane material, thereby reducing the difficulty of the operation and making the membrane changing operation more convenient.

[0062] Please refer to Figure 1 The bag making mechanism also includes 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 of fixed length is placed by a hose clamp. This station can use cut sections of hose, or can use a rolled hose and be equipped with a cutting assembly to cut the hose into the required fixed length.

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

[0065] The hose heat-sealing station 7 is arranged at 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 at one side of the peripheral heat sealing station 4, and is mainly used to cool and shape the hose welding part by driving the mold through the cylinder, and at the same time remove the waste edges and corners that may exist around the soft bag to ensure the welding quality of the soft bag and the hose.

[0067] The weak welding station 9 is used to process the part to be potted into a double-chamber or multi-chamber part. The weak welding station 9 mainly drives the heated mold to maintain a certain pressure and gap to weld the film material and the hose. Specifically, the hose is placed between the two layers of film of the soft bag and the welding operation is performed at the connection part. When welding once, the part to be potted is processed into two chambers. When welding multiple times, the part to be potted is processed into a soft bag with multiple chambers.

[0068] Please refer to Figure 1 , Figures 7 and 8 The upper hose station 5 is provided with an upper hose device, which includes a bracket 501, a rotating shaft 502 arranged on the bracket 501, and a support member 503. The support member 503 is sleeved on the rotating shaft 502. The bracket 501 is also provided with a driving device for driving the rotating shaft 502 to rotate. The driving device includes 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.

[0069] Specifically, the transmission sprocket 506 includes a driving sprocket and a driven sprocket, the driving sprocket is sleeved on the output shaft of the driving motor 504, the driven sprocket is sleeved on the rotating shaft 502, and the transmission chain 505 is meshed and connected between the driving sprocket and the driven sprocket. When the driving motor 504 is working, the driving sprocket drives the driven sprocket to rotate through the transmission chain 505, thereby driving the rotating shaft 502 to rotate, and the hose reel arranged on the support member 503 is unwound.

[0070] With such arrangement, the driving motor 504 provides pulling force to drive the hose reel to rotate and achieve unwinding, thereby avoiding the situation where the supply hose length is insufficient due to insufficient pulling force; and the length of the hose unwound each time can be adjusted by controlling the driving motor 504 to ensure usage requirements.

[0071] Please refer to Figure 1 The bag making mechanism also includes a bag transfer station 10, which is arranged at the rear end of the weak welding station 9, and the parts to be filled are transferred 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, it is transferred to the filling mechanism through the bag transfer station 10 so that the filling and nitrogen filling operations can be carried out simultaneously.

[0073] Please refer to Figure 1 The filling mechanism also includes a plugging station 12, a plugging station 14 and a bag output station 13.

[0074] The plugging station 12 is arranged at the rear end of the filling station 11 and is used to add sealing plugs to the filled parts.

[0075] The plugging station 14 is disposed at one side of the plugging station 12 and is used for delivering the sealing plug to the plugging station 12 .

[0076] The bag output station 13 is arranged at the rear end of the stoppering station 12, and is used to receive and output the bag to be filled after filling and stoppering.

[0077] The operation process of the multi-chamber soft bag making and filling machine provided by the present invention is as follows:

[0078] Film-applying station 1-printing station 2-film-drawing station 3-peripheral heat-sealing station 4-hose heat-sealing station 7-shaping station 8-weak welding station 9-bag transfer station 10-nitrogen filling station 15-filling station 11-plugging station 12-bag output station 13. The bag transfer station 10, the filling station 11, the plugging station 12 and the bag output station 13 are all set as a group. Under the premise of meeting the production speed requirements, the overall filling and sealing transmission length of the bag making and filling machine can be greatly shortened, the floor space of the equipment is reduced, and the equipment cost is reduced.

[0079] The multi-chamber soft bag making and filling machine provided by the present invention is provided with a separate nitrogen filling station 15, and nitrogen filling and filling are carried out simultaneously. Compared with filling and nitrogen filling being carried out separately, the system cycle time can be reduced and the production efficiency can be improved; the nitrogen filling station 15 is added with an exhaust device 151, which monitors the nitrogen concentration in real time through a pressure sensor and a flow meter and dynamically adjusts the nitrogen filling flow rate and the exhaust frequency, so that the residual oxygen content remains stable, the residual oxygen control accuracy is improved, and higher requirements can be met.

[0080] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
