[0035] The cutting assembly 5 includes a sliding frame 51, which is slidably mounted on the lower support rod 34, and a knife holder 52 is mounted on the top of the sliding frame 51, the knife holder 52 is slidably matched with the cutting groove 101, and a blade 53 is embedded in one end of the knife holder 52 facing the cutting groove 101, and support end seats 54 are mounted on both ends of the lower support rod 34, and screw rods 55 are rotatably mounted on the two support end seats 54 together, the sliding frame 51 is provided with a threaded through hole threadedly connected to the screw rod 55, and a servo motor 56 is fixedly mounted on one of the support end seats 54, the servo motor 56 is connected to the screw rod 55 through a pulley transmission, and the servo motor 56 is electrically connected to the control box 13 through a cable;

[0036] The driving mechanism 6 includes a connecting end plate 61 and a driving motor 64.

After cutting, the driving motor 64 is controlled to reverse, driving the voltage stabilizing component 4 and the cutting component 5 away from the substrate 1, releasing the pressure on the film, and resetting the blade 53 to the bottom of the cutting groove 101 to avoid scratches on the blade 53. Then, the film is pulled to a fixed length again, and the next cutting can be performed.

[0038] It should also be noted that the control box 13 is embedded with industrial control components such as a single-chip microcomputer or a PLC controller. Through programming, the control buttons on the control box 13 can control the relevant components to execute the set command actions. The specific control principles are all existing technologies and will not be described in detail here.

[0039] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 , grooves 103 are symmetrically provided on both sides of one end of the cutting groove 101 of the substrate 1, an L-shaped slider 7 is slidably installed in the groove 103, and a driving member 8 for driving the L-shaped slider 7 to slide is installed in the groove 103, and a rolling mechanism 9 is installed on the two L-shaped sliders 7, and the driving member 8 and the rolling mechanism 9 are both electrically connected to the control box 13;

[0040] The driving member 8 includes two screw rods 81, which are respectively installed in the grooves 103 symmetrically opened on the base plate 1 and are threadedly connected with the corresponding L-shaped slider 7, and one end of the two screw rods 81 is fixedly sleeved with a driven gear 82, and the end of the base plate 1 close to the driven gear 82 is rotatably installed with a transmission rod 83 and a power motor 85 for driving the transmission rod 83 to rotate, and the power motor 85 is electrically connected to the control box 13 through a cable, and the two ends of the transmission rod 83 are fixedly sleeved with a driving gear 84, and the driving gear 84 is meshed with the corresponding driven gear 82;

[0041] The rolling mechanism 9 includes an insertion rod 91, which is movably inserted into the through hole opened by the L-shaped slider 7, and one end of the insertion rod 91 extends into the slide groove 701 opened by the L-shaped slider 7, and is fixedly installed with a rectangular block 92. The rectangular blocks 92 on the two L-shaped sliders 7 are rotatably connected with a hollow pressure roller 94. A spring 93 is sleeved on the insertion rod 91, one end of the spring 93 is fixedly connected to the rectangular block 92, and one end of the spring 93 is fixedly connected to the top of the slide groove 701. A placement plate 95 is fixedly installed on the top of the L-shaped slider 7, and a battery 96 is installed on the placement plate 95. A shell 97 is installed on the rectangular block 92, and a fan 98 and a constant temperature resistor 99 are embedded in the shell 97, and the air outlet of the shell 97 is inserted into the hollow pressure roller 94. After the battery 96, the fan 98 and the constant temperature resistor 99 are electrically connected in sequence, they are electrically connected to the control box 13 through cables.

[0042] It should be noted that: when cutting the film, when the film is pulled and laid on the substrate 1, the control box 13 controls the power motor 85 to drive the transmission rod 83 to rotate, and the transmission rod 83 is meshed with the driven gear 82 through two driving gears 84, thereby driving the two screw rods 81 to rotate. When the two screw rods 81 rotate, the two L-shaped sliders 7 are driven to slide along the groove 103. When sliding, the fan 98 and the constant temperature resistance wire 99 are started synchronously to blow hot air into the hollow pressure roller 94. Therefore, during the movement of the L-shaped slider 7, the hollow pressure roller 94 is squeezed by the spring 93, and the hollow pressure roller 94 is always pressed on the film laid on the substrate 1, so that it is rolled to remove wrinkles, so as to avoid the film wrinkles affecting the quality of the packaging bag.

[0043] It should also be noted that a temperature controller for controlling the temperature rise of the constant temperature resistance wire 99 is provided in the control box 13 to ensure that the hollow pressing roller 94 maintains a suitable temperature during rolling to avoid burns and damage to the film caused by excessive temperature. The temperature controller is an industrial temperature control element commonly used in the prior art. The specific working principle will not be described in detail here, and the power motor 85 is controlled by the controller programming to alternately reverse, thereby controlling the driving member 8 to drive the L-shaped slider 7 to move back and forth for efficient wrinkle removal.

[0044] The working principle of the film cutting machine for food packaging bag processing provided by the utility model is as follows:

[0045] When in use, the packaging bag film is passed through the cutting groove 101 of the substrate 1, and then after being pulled to an appropriate length, the control box 13 controls the driving motor 64 to drive the bidirectional threaded rod 62 to rotate. The bidirectional threaded rod 62 rotates to drive the two transmission blocks 63 to move away from each other, thereby pulling the corresponding hinged seat 3 to slide on the guide rod 2. After the two hinged seats 3 move away from each other, the upper supporting rod 32 and the lower supporting rod 34 are pulled toward the cutting groove 101 through the upper connecting plate 31 and the lower connecting plate 33. When moving, the upper supporting rod 32 drives the stabilizing plate 43 through the screw 41 and the threaded sleeve 42 to press the film above the cutting groove 101 of the substrate 1, and the lower supporting rod 34 moves away from each other. When the blade 53 is moved, the sliding frame 51 and the knife frame 52 extend the blade 53 into the cutting groove 101 and the through groove 401, and then the servo motor 56 is started, and the servo motor 56 drives the screw rod 55 to rotate. When the screw rod 55 rotates, the sliding frame 51 is driven to move along the lower support rod 34, thereby driving the blade 53 to slide along the cutting groove 101 to cut the film above the cutting groove 101. After cutting, the driving motor 64 is controlled to reverse, drive the voltage stabilizing component 4 and the cutting component 5 away from the substrate 1, release the pressure on the film, and reset the blade 53 to the bottom of the cutting groove 101 to avoid scratching the blade 53. Then, the film is pulled to a fixed length again, and the next cutting can be performed.

[0046] During further cutting, when the film is pulled and laid on the substrate 1, the control box 13 controls the power motor 85 to drive the transmission rod 83 to rotate, and the transmission rod 83 is meshed with the driven gear 82 through two driving gears 84, thereby driving the two screw rods 81 to rotate. When the two screw rods 81 rotate, the two L-shaped sliders 7 are driven to slide along the groove 103. When sliding, the fan 98 and the constant temperature resistance wire 99 are synchronously controlled to start and blow hot air into the hollow pressure roller 94. Therefore, during the movement of the L-shaped slider 7, the hollow pressure roller 94 is squeezed by the spring 93, and the hollow pressure roller 94 is always pressed on the film laid on the substrate 1, so as to perform rolling roller wrinkle removal on it to avoid the wrinkle removal of the film affecting the quality of the packaging bag.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
