[0030] Reference Figures 1 to 5The utility model discloses a double-station tube film machine, including a frame 1 and a feeding mechanism 2 arranged on the frame 1. The structure and principle of the feeding mechanism 2 are basically the same as before, so the specific structure is not described in detail. The feeding mechanism 2 of the present application adopts a roller assembly for feeding, and the tube film on the film roll 3 is pulled out and sent to the first station by the drive of the roller. When at the first station, the station transfer mechanism will be activated to clamp and fix the tube film, and then the welding and sealing mechanism 1 will weld and seal the tube film and cut it. The welding and sealing of this process is the bag bottom of the packaging bag 4, and the cutting mechanism can cut the tube film located at the first station into packaging bags 4; after the above process is completed, the station transfer mechanism can transfer the packaging bag 4 to the second station, and the suction bag opening mechanism can absorb the packaging bag 4 located at the second station to open it to form an opening, and then the weighed material is input into the packaging bag 4 through the opening manually or by other equipment, and then the welding and sealing mechanism 2 can weld and seal the open end of the packaging bag 4 located at the second station, thereby forming a finished product.

[0031] As shown in the figure, the welding and sealing mechanism 1 includes a positioning plate 5 and a push plate 6 arranged on the frame 1, and the positioning plate 5 is provided with a heating wire 7. The push plate 6 is driven by the welding and sealing driving mechanism to push the tubular film onto the heating wire 7 for welding and sealing. The heating wire 7 is a product of the prior art, and thus the specific heating structure and principle of the heating wire 7 are not described in detail. The welding and sealing driving mechanism includes a welding and sealing cylinder 8 fixed to the positioning plate 5, a sliding hole relatively arranged on the positioning plate 5 and a sliding rod 9 matched with the sliding hole, one end of the sliding rod 9 is provided with a connecting plate 10, and the push plate 6 is fixed to the other end of the sliding rod 9. In the above structure, the sliding rod 9, the connecting plate 10 and the push plate 6 constitute an integral frame, and the movement of the push plate 6 can be realized by the push of the welding and sealing driving mechanism, thereby pushing the tubular film onto the heating wire 7 for welding and sealing.

[0032] As shown in the figure, the cutting mechanism includes a cutting cylinder 11 arranged on the push plate 6 and a cutting knife 12 connected to the cutting cylinder 11. The push plate 6 is provided with an avoidance groove, and the cutting knife 12 extends out through the avoidance groove. The cutting cylinder 11 will move with the push plate 6, so that the cutting knife 12 is at the side edge of the tubular film. When the welding is completed, the cutting cylinder 11 drives the cutting knife 12 to move in a straight line below the welding point to cut the tubular film into packaging bags 4, and the welding point on the tubular film will become the bottom of the next packaging bag 4. The above cutting simulates the daily cutting method. Compared with the existing punching cutting, the cutting effect is good.

[0033] As shown in the figure, the station transfer mechanism includes a transfer plate 13, a clamping cylinder 14 relatively arranged on the transfer plate 13, and a transfer drive mechanism arranged on the frame 1. The transfer plate 13 is moved by the transfer drive mechanism. The transfer drive mechanism is a linear motor fixedly installed on the frame 1. The transfer plate 13 is fixed on the linear motor, and the clamping cylinder 14 is fixed on the transfer plate 13. Therefore, the clamping cylinder 14 can be driven by the linear motor to be located at station one or station two. When located at station one, the clamping claws of the clamping cylinder 14 are opened, and the tubular film is fed in from above the clamping claws through the conveyance of the feeding mechanism 2, and the two sides of the tubular film are respectively located between the corresponding clamping claws. When the tubular film reaches the predetermined position, the clamping claws of the clamping cylinder 14 are closed, thereby clamping the two sides of the tubular film. After completing the process of station one, the packaging bag 4 is transferred to station two.

[0034] As shown in the figure, the suction bag opening mechanism includes a movable plate 16 and a movable plate 17. The movable plate 16 and the movable plate 17 are driven by a movable driving mechanism to move relative to each other. Suction cups 18 are provided on the movable plate 16 and the movable plate 17. Of course, the suction cups 18 are connected to the vacuum pump (not shown in the figure) through an air pipe. The suction cups 18 and the vacuum pump are both existing products, so their principles and installation structures are not described in detail. The movable plate 16 and the movable plate 17 first move toward each other so that the suction cups 18 respectively absorb the two sides of the packaging bag 4, and then the movable plate 16 and the movable plate 17 move away from each other, so that the suction cups 18 drive the two sides of the packaging bag 4 to separate, thereby forming an opening for convenient material transportation.

[0035] As shown in the figure, the frame 1 is provided with a driving motor, a driving reducer 19 matched with the driving motor, a linear bearing 20 and a sliding shaft 21 matched with the linear bearing 20, one end of the sliding shaft 21 is provided with an end plate 22, and the movable plate 16 is arranged at the other end of the sliding shaft 21, the driving reducer 19 is connected to the end plate 22 through a driving screw assembly 1, and the driving reducer 19 is connected to the movable plate 2 17 through a driving screw assembly 2. In the above structure, the sliding shaft 21, the end plate 22 and the movable plate 16 constitute an integral frame. Please use a driving reducer 19 to simultaneously connect screw assembly 1 and screw assembly 2, thereby driving the screws 23 in screw assembly 1 and screw assembly 2 to rotate. Because the thread rotation directions of the screws 23 in screw assembly 1 and screw assembly 2 are opposite, the end plate 22 connected to screw assembly 1 and the movable plate 1 16 and the movable plate 2 17 connected to screw assembly 2 will move toward each other or move away from each other, thereby achieving the action of making the suction cup 18 respectively suck the two sides of the packaging bag 4 and drive the two sides of the packaging bag 4 to separate. The above structure is realized by one motor, which saves costs.

[0036] As a further structure, the movable plate 17 is provided with avoidance holes, and the sliding shaft 21 passes through the avoidance holes, so that the space can be fully utilized and the structure is compact.

[0037] As shown in the figure, the second welding and sealing mechanism includes a heating wire arranged on the movable plate 2. When the weighed material is input into the packaging bag 4, the driving motor and the driving reducer 19 drive the movable plate 16 and the movable plate 2 17 to move toward each other through the screw rod. The movable plate 16 and the movable plate 2 17 push the two sides of the packaging bag to close and contact closely with the heating wire 7. The heating wire 7 generates heat to heat-seal the opening, and then the vacuum pump stops, and the suction cup 18 no longer absorbs the packaging bag. Then the driving motor and the driving reducer 19 drive the movable plate 16 and the movable plate 2 17 to move back and forth and separate through the screw rod, and the packaging bag will fall completely onto the tray 24. Of course, in the process where the suction cup 18 drives the two sides of the packaging bag 4 to separate, the heating wire is not working.

[0038] As shown in the figure, the frame 1 is provided with a tray 24 for holding the packaging bag 4. Because the packaging bag 4 needs to be loaded with materials, the support of the tray 24 can prevent the materials from damaging the packaging bag 4. As a further structure, the tray 24 can be adjusted in terms of lifting and lowering and the swing angle. Because the specifications and lengths of the packaging bags 4 are different, in order to better support the packaging bags 4, we need to adjust the position of the tray 24. The specific adjustment structure is that the lifting mechanism of the tray 24 includes a lifting screw rod 25 and a lifting nut matched with the lifting screw rod 25. The handle is connected to the lifting screw rod 25 through a pair of bevel gears 26. The screw rod 25 is connected, so when the handle is shaken, the lifting screw rod 25 can be driven to rotate, and the rotation of the lifting screw rod 25 drives the lifting nut to rise and fall. The lifting nut is fixed with a lifting seat 27. In order to guide the packaging bag 4 filled with materials to slide into the collection box below, the tray 24 needs to swing at an angle to make the packaging bag 4 slide down, so the tray 24 is hinged to the lifting seat 27. The swinging mechanism of the tray 24 is mainly a swinging cylinder 28. One end of the swinging cylinder 28 is hinged to the tray 24, and the other end is hinged to the lifting seat 27. When the swinging cylinder 28 is working, the tray 24 can be horizontal or tilted.

Specific examples are used in this article to illustrate the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
