Description
Technical Field
[0001] This utility model relates to the field of packaging bag sealing technology, specifically to a filling and sealing device for the production of self-heating packaging bags. Background Technology
[0002] A filling and sealing machine is a piece of equipment used in automated packaging production lines. Its main function is to accurately fill materials (such as liquids, powders, granules, etc.) into packaging bags and then seal them. This equipment can automatically complete the filling and sealing process and is widely used in the food, chemical, and pharmaceutical industries.
[0003] In the prior art, such as the Chinese patent with publication number CN219056767U entitled "A Sealing Device for Packaging Bags for Tile Adhesive Filling," the disclosed technical solution describes that the device moves the packaging bag to the clamping plate via a conveyor belt. The packaging bag pushes the clamping plate, causing the clamping plate to push the elastic element to contract. The elastic element's rebound force clamps the opening of the packaging bag. The distance between the limiting plates can be adjusted by the limiting plates and threaded pins to accommodate packaging bags with different opening sizes. However, there is a risk of the packaging bag shaking and tipping when it is being conveyed on the conveyor belt. This shaking and tipping can cause the filling to spill out, making it impossible to seal the packaging bag and reducing processing efficiency. Utility Model Content

A push rod is fixedly installed at the upper end of the hydraulic telescopic rod; the sealing assembly is located on the first base and is used to heat seal the filled packaging bag; the feeding mechanism transports the packaging bag, and the filling mechanism takes the packaging bag from the feeding mechanism and fills the heating agent into the packaging bag. After filling, the first hydraulic telescopic rod drives the push rod to move up and down repeatedly, so that the push rod repeatedly pushes the filled packaging bag, squeezing out the air between the heating agents in the packaging bag, making the heating agent fill the packaging bag more tightly, making the shape of the packaging bag more stable and facilitating subsequent transportation. Then, the filling mechanism places the filled packaging bag on the first conveyor belt. The filled packaging bag is guided by the first conveyor belt with V-shaped sides, reducing the possibility of shaking and tipping during transportation and facilitating subsequent sealing; the first conveyor belt transports the filled packaging bag to the sealing assembly for heat sealing.
[0006] Furthermore, the feeding mechanism includes a second base, which is located on one side of the first base. A second rotating roller is rotatably mounted on the second base, and a second motor is fixedly mounted on the second base. The output shaft of the second motor is fixedly connected to the second rotating roller. An auxiliary plate is fixedly mounted on the upper end of the second base near the first base. A second hydraulic telescopic rod is fixedly mounted on the lower end of the auxiliary plate near the first base. The second hydraulic telescopic rod passes through the auxiliary plate. A movable plate is fixedly mounted on the upper end of the second hydraulic telescopic rod. An upper suction pump is fixedly mounted on the upper end of the movable plate, and a lower suction pump is fixedly mounted on the lower end of the auxiliary plate. The positions of the lower suction pump and the upper suction pump correspond to those of the upper suction pump. The packaging bag is placed on the second conveyor belt, with the open end of the packaging bag placed on the auxiliary plate. The packaging bag is conveyed to the lower opening of the movable plate. The second hydraulic telescopic rod drives the movable plate to move downward so that the lower end of the second hydraulic telescopic rod contacts the packaging bag. At this time, the lower suction pump and the upper suction pump are activated to suck up the packaging bag respectively. The second hydraulic telescopic rod drives the movable plate to move upward so that the open end of the packaging bag opens.
[0007] Furthermore, the filling mechanism includes a mounting frame, which is mounted above the first hydraulic telescopic rod and fixedly mounted on the first base. An external feed inlet is fixedly mounted on the mounting frame, and an opening / closing port is hinged to the lower end of the external feed inlet. A clamping plate is provided on the outside of the opening / closing port and is fixedly mounted on the external feed inlet. A friction plate is fixedly mounted on the end of the clamping plate near the opening / closing port. A rotating shaft is rotatably mounted on the mounting frame, and a third motor is fixedly mounted on the mounting frame. The output shaft of the third motor is fixedly connected to the rotating shaft, and a transfer rod is movably mounted on the rotating shaft. There are two transfer rods, and a third hydraulic telescopic rod is fixedly mounted between the two transfer rods. The transfer rod is L-shaped. The third motor drives the transfer rod to rotate through the rotating shaft, so that the lower end of the L-shaped transfer rod extends into the open packaging bag at the opening end of the feeding mechanism. The third hydraulic telescopic rod is activated to push the two transfer rods away, causing the transfer rod to open the packaging bag. The third motor drives the transfer rod to rotate again through the rotating shaft, so that the transfer rod drives the packaging bag to rotate and fit into the opening / closing port. The opening / closing port opens and clamps the packaging bag with the clamping plate, filling the packaging bag with heating agent.
[0008] Furthermore, the sealing assembly includes a sealing plate, a heating plate, a fourth hydraulic telescopic rod, and a push plate. There are two sealing plates, which are fixedly installed on the first base. The ends of the two sealing plates near the filling mechanism are V-shaped. The heating plate is fixedly installed on one sealing plate, and a fixing plate is fixedly installed on the other sealing plate. The fourth hydraulic telescopic rod is fixedly installed on the fixing plate, and a push plate is fixedly installed on the end of the fourth hydraulic telescopic rod near the heating plate. The opening of the filled packaging bag is allowed to enter between the sealing plates through the V-shaped opening. The fourth hydraulic telescopic rod is activated to push the push plate, causing the heating plate and the push plate to clamp the packaging bag, thereby heat-sealing the opening of the packaging bag.
[0009] The beneficial effects are: the first hydraulic telescopic rod drives the push rod to move up and down repeatedly, causing the push rod to repeatedly push the filled packaging bag, squeezing out the air between the heating agent in the packaging bag, making the heating agent fill the packaging bag more tightly, making the shape of the packaging bag more stable, and making the packaging bag more stable and less likely to tip over after it falls onto the first conveyor belt;
[0010] The packaging bag is guided by the first conveyor belt with V-shape on both sides, which further reduces the possibility of shaking and tipping during transportation and facilitates subsequent sealing. Attached Figure Description

The packaging bag is conveyed to the lower opening of the moving plate 250. The second hydraulic telescopic rod 240 drives the moving plate 250 to move downward so that the lower end of the second hydraulic telescopic rod 240 contacts the packaging bag. At this time, the lower suction pump 230 and the upper suction pump 260 are started to suck up the packaging bag respectively. The second hydraulic telescopic rod 240 drives the moving plate 250 to move upward so that the open end of the packaging bag opens; The three motors 330 drive the transfer rods 340 to rotate via the shaft 320, causing the lower end of the L-shaped transfer rods 340 to extend into the open packaging bag on the feeding mechanism. The third hydraulic telescopic rod 341 is activated to push the two transfer rods 340 away, causing the transfer rods 340 to open the packaging bag.
