[0011] The working principle of the utility model is:

[0012] A. Installing the new film: Assuming that the old film B has been installed on the second film roll turning frame 3, manually install the new film roll A on the first film roll turning frame 4, and then pull the head of the new film A forward to a proper distance beyond the front end of the new film supporting plate 53, and the pressing plate cylinder 55 drives the new film pressing plate 54 to descend, so that the new film A is pressed tightly on the new film supporting plate 53;

[0013] B. Cutting off the old film: When the old film B on the second film roll turning frame 3 is about to run out, the packaging machine stops running, the side shaping cylinders 121 on the left and right sides drive the side shaping plates 122 to move inwards to center the old film B, the clamping cylinder 77 drives the old film clamping mechanism 7 to swing and close, so that the old film B is pressed against the support plate 62, the old film cutting rodless cylinder 91 drives the cutter 92 located in the first cutting long groove 64 and the second cutting long groove 78 to move horizontally to cut off the old film B, and the old film clamping mechanism 7 returns to the initial position;

[0014] C. The old film gives way to the new film: the pressure rod cylinder 79 drives the swing pressure rod 75 to swing downward so that the old film B is pressed against the support plate 62, and the support plate cylinder 65 drives the support plate 62 to drive the old film B to swing downward. At the same time, the pressure rod cylinder 79 continues to extend, so that the old film B is always pressed against the support plate 62 by the swing pressure rod 75;

[0015] D. New film feeding: The two-station slide 2 slides along the base 1, so that the new film A installed on the first film roll turning frame 4 is located directly behind the overlapping heat sealing device, and the film feeding cylinder 56 drives the new film transfer frame 52 to move forward, driving the new film A pressed on the new film supporting plate 53 to the bottom of the heat sealing assembly 81;

[0016] E. Heat-sealing the new film and the old film: the support plate cylinder 65 drives the support plate 62 to swing upward to drive the old film B back to a horizontal state, and at the same time the swing pressure rod 75 returns to the initial position. At this time, the lower surface of the new film support plate 53 presses on the old film B, and the new film A overlaps the old film B. The heat-sealing cylinder 85 drives the heat-sealing mechanism 8 to swing downward and close, and the heat-sealing assembly 81 is heated to heat-seal the new film A and the old film B together. The sealing cooling air duct 86 blows out cold air to cool and solidify the heat-sealed part;

[0017] F. Film splicing is completed: the heat sealing cylinder 85 drives the heat sealing mechanism 8 back to the initial position, the side shaping cylinders 122 on the left and right sides drive the side shaping plates 123 to move outward to the initial position, the pressing plate cylinder 55 drives the new film pressing plate 54 to rise and detach from the new film A, and the film feeding cylinder 56 drives the new film transfer frame 52 to move backward and back to the initial position, thus completing the automatic film splicing;

[0018] G. Film roll deviation correction: After the film is connected, the left side of the new film A passes through the film feed guide plate 132, and the first sensor 133 sends a signal that the new film A is detected, which is the normal film feeding state of the new film A; when the second sensor 134 also sends a signal that the new film A is detected, the external control system determines that the new film A is deviated to the left, and controls the two-station slide 2 to slide to the right along the base 1, driving the new film A installed on the first film roll turning frame 4 to move to the right, so that the second sensor 134 no longer sends a signal that the new film A is detected, and the new film A returns to the normal film feeding state; when the first sensor 133 does not send a signal that the new film A is detected, the external control system determines that the new film A is deviated to the right, controls the two-station slide 2 to slide to the left along the base 1, driving the new film A installed on the first film roll turning frame 4 to move to the left, so that the first sensor 133 sends a signal that the new film A is detected again, and the new film A returns to the normal film feeding state.

[0019] The beneficial effects of the utility model are:

[0020] A. When the packaging machine does not have an M-side film separation plate structure, the new film A and the old film B are overlapped and heat-sealed to simplify the film splicing structure and improve the efficiency of automatic film splicing.

[0021] B. By utilizing the cooperation between the support plate mechanism 6 and the swing pressure rod 75, the cut old film B can swing downward with the support plate mechanism 6 without deviation, avoiding the new film A horizontally transferred by the new film clamping transfer mechanism 5, so that the front end of the new film A does not touch the rear end M of the old film B when it is transferred forward to cause bending. After the new film A is transferred into place, the old film B swings upward and overlaps under the new film A, ensuring the flatness of the subsequent heat sealing position, so that the seam can smoothly pass through the bag feeding mechanism of the subsequent packaging machine, and improving the reliability of the equipment.

[0022] C. The two-station film roll turning rack is set up to ensure the automatic switching and connection when replacing the old film with the new film, and improve the work efficiency when changing the film roll.

[0023] D. The film shaping mechanism 12 is used to ensure that the old film A is in the center, so that the new and old films are aligned and flat when overlapped, thus ensuring the flatness of the heat-sealed seam.

[0024] E. By using the cooperation between the film roll deviation detection component 13 and the two-station slide 2, a real-time automatic deviation correction function is realized during the film feeding process, avoiding the problem of leaking the mouth seal and bottom seal during subsequent bag making, and improving the reliability of the equipment.
