Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

As shown in fig. 1, the bag making machine with the automatic edge cutting function device provided by the utility model comprises a bag making machine main body 1, a material collecting table 2 for bearing film bags is arranged below a discharge hole of the bag making machine main body 1, and a cutting mechanism 3 for cutting the film bags is arranged inside the discharge hole of the bag making machine main body 1. The cutting mechanism 3 includes a base member 31, an air cylinder 32, and an upper member 33. The bottom member 31 includes a frame-shaped base 311 provided inside the bag machine main body 1, and press plates 312 are provided inside the frame-shaped base 311 in bilateral symmetry. The top of clamp plate 312 is installed telescopic link group 313, and the top of telescopic link group 313 is fixedly connected with link plate 314. A spring 315 for return adjustment is connected between the connecting plate 314 and the frame base 311.

The upper member 33 includes a mounting plate 331 fixedly coupled to the output end of the air cylinder 32, and a pressing plate group 333 for pressing the coupling plate 314 and a blade 332 for cutting the film pouch are provided at the bottom of the mounting plate 331.

In this embodiment, guide grooves are formed in the front and rear inner walls of the bag making machine body 1, guide blocks are slidably connected in the guide grooves, and one side, away from the guide grooves, of the guide blocks is fixedly connected to the mounting plate 331, so that the mounting plate 331 is guided along with the movement of the air cylinder 32.

The working principle of the bag making machine with the automatic edge cutting function device based on the first embodiment is as follows: when the film bag is heat-sealed and formed in the bag making machine main body 1, the film bag is cut by the cutting mechanism 3 and separated when the film bag is conveyed to the bag making machine main body 1. When the cutting mechanism 3 cuts edges of the film bag, the portion of the film bag to be cut passes through the frame-shaped base 311 of the middle sole member 31 of the cutting mechanism 3. After it reaches the cutting position, the film bag stops being transported and the cylinder 32 is operated. The movement of the air cylinder 32 causes the mounting plate 331 in the upper member 33 to move downward, and the downward movement of the mounting plate 331 causes the pressing plate group 333 and the blade 332 to move downward simultaneously. The pressing plate group 333 presses the connecting plate 314 during the downward movement, so as to compress the spring 315, and the pressing plate 312 is driven to move downward for adjustment by the telescopic rod group 313. The pressing plate 312 contacts the film bag in the downward moving process, and then the blade 332 continuously moves downward along with the continuous output of the air cylinder 32, and the telescopic rod group 313 performs shrinkage adjustment, so that the pressing plate 312 compresses and fixes the film bag when the film bag is cut, and the film bag is prevented from being deviated. When the film bag is cut, the air cylinder 32 moves up to an initial state, and as the air cylinder 32 is restored, the bottom part 31 is restored to the initial state under the action of the spring 315, the cut film bag falls onto the collecting table 2 from the discharge hole thereof, and the subsequent film bag is continuously fed.

Example two

As shown in fig. 1-2, based on the first embodiment, this embodiment further includes: the inner wall of the bottom of the bag making machine main body 1 is provided with a groove, the frame-shaped base 311 is fixedly connected in the groove, and the inner wall of the bottom of the frame-shaped base 311 is provided with a knife groove. A through groove positioned on the top shell wall of the frame-shaped base 311 is formed above the knife groove, the bottom of the knife blade 332 penetrates through the through groove, and the bottom end of the knife blade 332 is matched with the knife groove. The symmetrical pressing plates 312 are respectively disposed at two sides of the through groove, and the telescopic rod group 313 includes two telescopic rods, which are disposed symmetrically front and back.

In this embodiment, the setting of the telescopic rods in the telescopic rod group 313 makes the pressing plate 312 move downwards along with the continuous movement of the blade 332 after contacting the film bag, so that the blade 332 performs shrinkage adjustment, and when the blade 332 completes the edge cutting operation, the pressing plate 312 ensures the pressing and fixing of the film bag.

Example III

As shown in fig. 1, based on the first or second embodiment, the present embodiment further includes: the air cylinder 32 is connected to the top outer wall of the bag machine body 1 by a screw, and the output end of the air cylinder 32 extends into the interior of the bag machine body 1. The squeeze plate group 333 includes two squeeze plates, which are disposed on two sides of the blade 332, respectively, and are located right above the connecting plate 314.

In this embodiment, the squeeze plates in the squeeze plate group 333 correspond to the plurality of link plates 314, and further squeeze the plurality of link plates 314 synchronously after descending along with the operation of the air cylinder 32.
