The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a film feeding mechanism is provided.

[0019] Example 1: like Figure 1-3 As shown, the film feeding mechanism according to an embodiment of the present utility model includes a base plate 1, with sliding blocks 2 symmetrically connected on both sides of the top of the base plate 1, a horizontal plate 3 on the top of the two sets of sliding blocks 2, a vertically arranged frame 4 on the top of the horizontal plate 3, and a film feeding assembly 5 symmetrically connected on one side of the frame 4. The film feeding assembly 5 includes a horizontally arranged mounting frame 6 and a mounting frame 7. The mounting frame 6 and the mounting frame 7 are provided with a sliding block 8 at their close ends. The two sets of sliding blocks 8 are respectively provided with an upper film opening mechanism 9 and a lower film opening mechanism 10 for opening the film. The mounting frame 6 and the mounting frame 7 are each provided with a synchronous belt 11 for driving the sliding block 8 to move. The ends of the mounting frame 6 and the mounting frame 7 are provided with synchronous pulleys 12 for driving the synchronous belts 11 to rotate. One set of synchronous pulleys 12 is equipped with a motor 13.

[0020] Example 2: like Figure 1-3 As shown, both mounting bracket 6 and mounting bracket 7 are equipped with drag chains 14 connected to the slide block 8. A lead screw 15 is vertically rotatably connected to the middle of the frame 4. A sliding block 16 is threaded onto the lead screw 15 and is slidably connected to the frame 4. Two sets of sliding blocks 16 are correspondingly connected to the mounting bracket 6. A motor 2 17 for driving the lead screw 15 to rotate is provided at the top of the frame 4.

[0021] Example 2: like Figure 1-3 As shown, a sleeve block 18 is provided at the bottom center of the horizontal plate 3, and a screw rod 19 threaded through the sleeve block 18 is provided at the top of the base plate 1. One end of the screw rod 19 is connected to a motor 20. A slide table 21 connected to the frame 4 is slidably connected to the top of the base plate 1.

Cylinders 23 are respectively installed on the upper film opening mechanism 9 and the lower film opening mechanism 10.

[0022] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0023] In practical applications, the motor 20 drives the lead screw 19 to rotate, causing the horizontal plate 3 and its top components to move left and right with the forward and reverse rotation of the lead screw 19, thus displacing the film feeding assembly 5. The cylinder 23 on the film feeding assembly 5 is connected to the upper film opening mechanism 9 and the lower film opening mechanism 10 to control their forward and backward movement. The upper film opening mechanism 9 and the lower film opening mechanism 10 are inserted into the prepared film bag. The upper film opening mechanism 9 and the lower film opening mechanism 10 are controlled by the motor 2 17 to move up and down on the lead screw 15 to adjust the direction of the film bag. During the film pulling process, the lower film opening mechanism 10 shapes the flat bag film into a square shape to ensure that the packaging box can enter the bag. The film pulling assembly 5 leaves and delivers the bag film to the predetermined position, waiting for the packaging box to be delivered.

[0024] In summary, with the help of the above-mentioned technical solution of this utility model, the cylinder 23 connects the upper film-opening mechanism 9 and the lower film-opening mechanism 10 to control their forward and backward movement. The upper film-opening mechanism 9 and the lower film-opening mechanism 10 are inserted into the prepared film bag. The upper film-opening mechanism 9 is controlled by the motor 217 to move upward on the lead screw 15 to adjust the direction of the film bag and shape the flat bag film into a square shape to ensure that the packaging box can enter the bag. The film-pulling assembly leaves and sends the bag film to the predetermined position to wait for the packaging box to arrive. This not only improves the conveying speed, but also makes the front and rear film cutting and packaging easier to operate.
