Description

Technical Field

[0001] This utility model relates to the field of stand-up pouch production technology, specifically to piston-type filling equipment for stand-up pouch production lines. Background Technology

[0002] As is well known, stand-up pouches are mainly used in products such as fruit juices, sports drinks, bottled drinking water, squeezable jellies, and condiments. Besides the food industry, their use is also gradually increasing in products such as detergents, daily cosmetics, and pharmaceuticals. A stand-up pouch is a flexible packaging bag with a horizontal support structure at the bottom, which can stand upright without any support and regardless of whether it is opened or not.

[0003] However, traditional stand-up pouch filling production lines typically use rotary filling, which requires many workstations, occupies a large space, and cannot accommodate inkjet printers, thus reducing the work quality and efficiency of stand-up pouch filling production. Therefore, we propose a piston filling device for stand-up pouch production lines to solve the aforementioned problems. Utility Model Content

[0028] In one embodiment, such as Figures 1-6 As shown, the piston filling equipment of the stand-up pouch production line includes:

[0029] Piston-type filling mechanism 1;

[0030] The liquid storage tank 2 is located on one side of the piston filling mechanism 1;

[0031] The cap-feeding mechanism 3 is located on one side of the piston-type filling mechanism 1;

[0032] The inkjet printer 4 is located below the cover feeding and cover-carrying mechanism 3;

[0033] The capping mechanism 5 is located above the inkjet printer 4;

[0034] Automatic bag feeding mechanism 6 is located on one side below the cap feeding and cap-attaching mechanism 3;

[0035] The piston-type filling mechanism 1 includes a filling lifting cylinder 7. A filling cylinder piston rod 8 is provided on one side of the filling lifting cylinder 7. A filling cylinder barrel 9 is provided below the filling cylinder piston rod 8. A filling cylinder barrel limiting plate 10 is provided below the filling cylinder barrel 9. A conical piston 11 is provided at the lower end of the filling cylinder piston rod 8. A conical piston sleeve 12 is provided at the lower end of the conical piston 11. A piston sleeve limiting plate 13 is provided at the lower end of the conical piston sleeve 12. The outer side wall of the conical piston sleeve 12 is in contact with the inner side wall of the piston cylinder barrel 9.

[0036] The capping mechanism 5 includes a capping lifting cylinder 14. A sheet metal part is provided at the lower end of the capping lifting cylinder 14. A capping motor is provided on the lower end wall of the sheet metal part. The motor shaft of the capping motor is connected to a rotating shaft 15 through a set screw. A rotating sleeve 16 with a brake pad is sleeved on the outer side of the lower end of the rotating shaft 15. A capping rubber 17 is provided on the lower end surface of the rotating sleeve 16 with a brake pad. A set of sealing rings is provided on the outer side of both the conical piston 11 and the conical piston sleeve 12. A one-way valve is provided at the bottom of the filling lifting cylinder 7.

[0037] Specifically, during filling, the filling lifting cylinder 7 and the filling cylinder piston rod 8 are connected by sheet metal parts. The filling cylinder piston rod 8 and the conical piston 11 are connected by a pin. The bottom center of the conical piston 11 is drilled with a threaded hole. The piston sleeve limiting plate 13 is fixed to the screw by a snap ring and connected to the conical piston 11. When the filling cylinder piston rod 8 rises, it drives the conical piston sleeve 12. At the same time, there is a certain gap between the conical piston 11 and the conical piston sleeve 12 to allow the liquid to flow through. Both the conical piston 11 and the conical piston sleeve 12 have sealing rings on their outer sides. During filling, the filling cylinder 9 descends to the position of the filling cylinder limiting plate 10 due to the friction of the sealing rings. At this time, the bottom thin tube enters the self-standing bag packaging. The filling cylinder piston rod 8 continues to descend, driving the conical piston 11 and the conical piston sleeve 12 to pump the liquid into the self-standing bag. After a 1-second delay, the liquid in the storage tank 2 enters the filling cylinder 9 from the top of the filling lifting cylinder 7 and is exhausted from the top exhaust pipe. Then, the piston rod 8 of the filling cylinder rises, first driving the filling cylinder 9 to rise. After reaching the filling cylinder limit plate 10, the filling cylinder 9 stops rising. At this point, the thin tube is pulled out of the stand-up pouch. The piston rod 8 of the filling cylinder continues to rise, causing the liquid above the filling cylinder 9 to flow through the gap between the conical piston 11 and the conical piston sleeve 12. Because there is a one-way valve at the bottom of the filling lifting cylinder 7, the liquid will remain inside the filling lifting cylinder 7. Afterwards, the stand-up pouch passes through the capping mechanism 3 and reaches directly below the capping mechanism 5. Simultaneously with the capping, the piston-type filling mechanism 1 begins filling the next pouch. In the capping mechanism 5, the capping lifting cylinder 14 is connected to the capping motor via sheet metal parts. The rotating shaft 15 is connected to the motor shaft via a set screw. The rotating sleeve with a brake pad is connected to the rotating shaft 15 by inserting an M4 screw into the groove of the rotating shaft 15. At the same time, an M10 set screw holds a rubber pad against the rotating shaft 15. The capping force is adjusted by adjusting the depth of the set screw, which also prevents the motor from seizing up after capping. The capping rubber 17 provides the capping friction. When capping, the capping motor starts, the cylinder rod of the capping lifting cylinder 14 descends until the capping rubber 17 tightens the cap. After a 1-second delay, the cylinder rod of the capping lifting cylinder 14 rises, and the capping ends. After the next stand-up pouch is filled, it moves directly under the capping mechanism 5 and pushes the capped stand-up pouch to the workbench opening to make it fall, thus ending the filling process. By setting up a piston-type filling mechanism 1, a liquid storage tank 2, a capping and attaching mechanism 3, an inkjet printer 4, a capping mechanism 5, and an automatic bag feeding mechanism 6, filling, inkjet printing, capping, and capping are integrated into one unit, reducing the size of the equipment while improving production efficiency. The produced stand-up pouches are of standard weight, and the caps are tightly attached, improving the work quality and efficiency of stand-up pouch production, making it quite practical.

[0038] The above embodiments disclose piston-type filling equipment for stand-up pouch production lines. During filling, the filling lifting cylinder 7 and the filling cylinder piston rod 8 are connected by sheet metal parts. The filling cylinder piston rod 8 and the conical piston 11 are connected by a pin. A threaded hole is drilled at the center of the bottom of the conical piston 11. The piston sleeve limiting plate 13 is fixed to the screw by a snap ring and connected to the conical piston 11. When the filling cylinder piston rod 8 rises, it drives the conical piston sleeve 12. At the same time, there is a certain gap between the conical piston 11 and the conical piston sleeve 12. The gap allows liquid to flow through. Both the conical piston 11 and the conical piston sleeve 12 have sealing rings on their outer sides. During filling, the filling cylinder 9 descends to the filling cylinder limit plate 10 position due to the friction of the sealing rings. At this time, the bottom thin tube enters the stand-up pouch packaging. The filling cylinder piston rod 8 continues to descend, driving the conical piston 11 and the conical piston sleeve 12 to pump the liquid into the stand-up pouch. After a 1-second delay, the liquid in the storage tank 2 enters the filling cylinder 9 from the top of the filling lifting cylinder 7 and is exhausted from the top exhaust pipe. Then, the filling cylinder piston rod 8 rises, first driving the filling cylinder 9 to rise. After reaching the filling cylinder limit plate 10, the filling cylinder 9 stops rising. At this time, the thin tube is withdrawn from the stand-up pouch. The filling cylinder piston rod 8 continues to rise, allowing the liquid in the upper part of the filling cylinder 9 to flow through the gap between the conical piston 11 and the conical piston sleeve 12. Because there is a one-way valve at the bottom of the filling lifting cylinder 7, the liquid will remain in the filling lifting cylinder 7. Afterwards, the stand-up pouch passes through the cap-attaching mechanism 3 and arrives directly below the capping mechanism 5. Simultaneously, the piston-type filling mechanism 1 fills the next pouch. The capping mechanism 5's capping lifting cylinder 14 is connected to the capping motor via sheet metal parts. The rotating shaft 15 is connected to the motor shaft via a set screw. A rotating sleeve with a brake pad is connected to the rotating shaft 15 via an M4 screw inserted into its groove. Simultaneously, an M10 set screw holds a rubber pad against the rotating shaft 15. The capping force is adjusted by changing the depth of the set screw, preventing the motor from seizing up after capping. The capping rubber 17 provides friction for capping. During capping, the capping motor starts, and the cylinder rod of the capping lifting cylinder 14 descends until the capping rubber 17 tightens the cap. After a 1-second delay, the cylinder rod of the capping lifting cylinder 14 rises, ending the capping process. After the next stand-up pouch is filled, it moves directly below the capping mechanism 5 and is pushed to the worktable notch to fall, completing the filling process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
