A first sensor and a second sensor are respectively provided on both sides of the conveyor belt. The operation of the feeding motor is controlled by the signals of the first sensor and the second sensor.

3. The compatible plastic packaging machine according to claim 1, characterized in that: The bag making assembly includes a film clamping component, a film pulling component, and a cutter component. The cutter component is provided with a cutter for thermally cutting the plastic film. The film pulling component is provided with a telescopic clamping plate for clamping the side of the plastic film, and a linear slide rail for controlling the movement of the telescopic clamping plate. The film clamping component includes two groups of telescopic clamping plates for clamping the plastic film pulled by the film pulling component.

4. The compatible plastic packaging machine according to claim 1, characterized in that: The box pushing and bag entering assembly includes a box pushing linear slide, a box pushing motor, a push plate and a split plate. The slider of the box pushing linear slide is driven by the box pushing motor and is fixedly connected to the push plate and the split plate through a translational linear slide. The split plate includes two side plates located on both sides of the push plate. The two side plates can realize relative movement through the driving motor, and move to both sides at the same time or move toward the push plate at the same time.

5. The compatible plastic packaging machine according to claim 1, characterized in that: The sealing assembly includes a cutter anvil, a second cutter, a first waste cylinder, a second waste cylinder, a third waste cylinder and a suction cup. The cutter anvil and the second cutter cooperate with each other. The second cutter is located above the cutter anvil, and a suction cup is provided at the front end. The suction cup is raised and lowered by the second waste cylinder, the second waste cylinder is moved left and right by the first waste cylinder, and the first waste cylinder is raised and lowered by the third waste cylinder.

6. The compatible plastic packaging machine according to claim 1, characterized in that: The corner cutting assembly includes two parallel base rails, each of which is provided with two corner cutting devices, which can slide on the base rails. Each corner cutting device is provided with a film pressing and sorting assembly, a waste material suction assembly and a cutter assembly.

7. The compatible plastic packaging machine according to claim 1, characterized in that: The conveying assembly includes a conveying motor and a conveying track. The conveying track includes rollers fixed at the front and rear ends, and a conveyor belt connecting the two rollers. The front roller is driven by the conveying motor, and the rear roller is driven to rotate through the conveyor belt.

8. The compatible plastic sealing packaging machine according to claim 3, characterized in that: The cutter component includes a cutter fixing frame, and a push rod and a slide rod are provided on the cutter fixing frame. The slide rod is provided with two groups, the lower end of which is fixedly connected to the cutter, and the upper end is slidably connected to the cutter fixing frame to prevent the cutter from deflecting. The lower end of the slide rod and the lower end of the push rod are fixedly connected by a connecting rod. The push rod adopts an electric push rod, which drives the cutter to move up and down to achieve thermal cutting of the plastic film.
