[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This bag-making machine for producing composite film bags with a waste removal structure is equipped with a waste removal mechanism. The waste removal mechanism allows waste from the bottom of the bag-making machine body to fall onto the top of the moving frame. Through the electrostatic generator on one side of the moving frame, the composite film can be electrostatically adsorbed. In addition, by disconnecting the contact block, the moving frame can easily extend out of the discharge port, facilitating the removal of waste. The specific details are as follows:

[0015] 1. A movable frame is provided, and the rotating disk inside the movable frame can rotate. The rotation of the outer end of the rotating disk causes the connecting rod to rotate, which in turn drives the two sets of bonding plates to move relative to each other via the sliding rod. This can limit the composite film bag that needs to be cut, facilitating the subsequent cutting process of the cutting blade. Furthermore, by providing an electric push rod, the output end of the electric push rod drives the movable frame to move, which allows the contact block on one side of the movable frame to detach from the inner wall of the bag making machine body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a bag making machine for producing composite film bags with a waste removal structure.

[0026] Example 1: To address the shortcomings of current bag-making machines in actual operation, such as waste material accumulating inside the device during the cutting of heat-sealed composite film bags, which makes cleaning difficult, please refer to the attached document. Figure 1 Appendix Figure 5 and attached Figure 6The system includes a bag-making machine body 1 and a feed inlet 2 located at the center of the top of the bag-making machine body 1. Inside the bag-making machine body 1, a cutting blade 10 is installed for cutting. A waste removal mechanism is located at the bottom of the bag-making machine body 1 to discharge waste material after cutting inside the bag-making machine body 1. A transparent plate 101 is installed on the surface of the bag-making machine body 1, and a discharge port 102 is located on the lower side of the surface of the bag-making machine body 1. An electric push rod 11 is fixed to the back of the bag-making machine body 1. The waste removal mechanism includes a movable frame 12 fixed to the output end of the electric push rod 11. A rotating disk 13 is rotatably mounted inside the movable frame 12, and connecting rods 14 are rotatably connected to both sides of the edge of the rotating disk 13. The outer end of the connecting rod 14 is rotatably positioned at the bottom center of the bonding plate 15. Both ends of the bonding plate 15 are slidably positioned on the outer side of the slide rod 16. A contact block 17 is also installed on the side of the moving frame 12 near the electric push rod 11. The moving frame 12 is made of metal plate, and an electrostatic generator with an independent power supply is connected to one side of the moving frame 12. One side of the contact block 17 is attached to the inner wall of the bag making machine body 1. After the contact block 17 is attached to the inner wall of the bag making machine body 1, the electrostatic generator is turned on. Both ends of the slide rod 16 are fixed to the inner side of the moving frame 12. The bottom end of the rotating disk 13 is fixed to the output end of the motor. The bonding plate 15 forms a sliding structure between the outer side of the connecting rod 14 and the slide rod 16.

[0027] First, when removing waste from the composite film bags to be processed inside the bag making machine body 1, the electric push rod 11 drives the moving frame 12 to the bottom center position of the bag making machine body 1. At this time, the contact block 17 fixed on one side of the moving frame 12 will be in a squeezed state, thereby energizing the electrostatic generator on one side of the moving frame 12, thus energizing the moving frame 12 and ensuring that the moving frame 12 can generate static electricity, so that the moving frame 12 can adsorb the waste from the cutting of the composite film bags to be processed. In addition, before cutting, the motor at the bottom of the moving frame 12 can be started. The output end of the motor can drive the rotating disk 13 to rotate, which in turn drives the two sets of connecting rods 14 to move. The other end of the connecting rod 14 is rotatably set at the bottom center position of the bonding plate 15, so that the bonding plate 15 slides on the outside of the slide rod 16, which can clamp the bottom position of the composite film bags to be processed, facilitating the subsequent cutting process.

[0028] Example 2: To facilitate the subsequent cutting of the composite film bags to be processed, please refer to the attached document. Figure 1 - Appendix Figure 4A rotary motor 3 is fixedly installed on one side of the top of the bag making machine body 1. The output end of the rotary motor 3 is fixed to the end of the bidirectional lead screw 4. The rotation of the bidirectional lead screw 4 enables the fixing mechanism inside the bag making machine body 1 to drive the two sets of pressure rollers 7 to move relative to each other, thereby pressing the heat-sealed composite film bag. The fixing mechanism includes a threaded connector 5 threaded to the outer side of the bidirectional lead screw 4. The outer end of the threaded connector 5 is slidably set in the guide groove 6 opened in the side wall of the bag making machine body 1. The outer end of the threaded connector 5 is fixedly set to the end of the pressure roller 7. The end of the pressure roller 7 away from the threaded connector 5 extends out of the outer side of the bag making machine body 1. The inner side of the pressure roller 7 is slidably set on the outer side of the guide rod 8. The two ends of the guide rod 8 are fixed to the upper outer wall of the bag making machine body 1. Two sets of pressure rollers 7 are symmetrically distributed about the transverse center line of the bag making machine body 1.

[0029] After the composite film bag to be processed is placed inside the bag making machine body 1, it can be limited by two sets of bonding plates 15. Then, by starting the rotating motor 3, the output end of the rotating motor 3 drives the bidirectional lead screw 4 to rotate, and the threaded connector 5 connected to the outer end of the bidirectional lead screw 4 drives the pressure roller 7 to slide inside the guide groove 6. This allows the pressure roller 7 to limit the upper outer side of the composite film bag to be processed. The position sensor 9 detects the bottom position of the moving frame 12. Then, by starting the cutting blade 10, the outer side of the cutting blade 10 cuts the composite film to be processed.
