[0024] Embodiments

[0025] AsFigures 1 to 4 As shown, the present invention proposes a food packaging heat-sealing film slitting machine, which includes a slitting machine body 1 and a heat-sealing film 4, and further includes: a slide rail 2 fixedly connected to the bottom of the slitting machine body 1, and multiple pairs of sliding seats 23 supporting the heat-sealing film 4 are slidably provided on the slide rail 2.

[0026] Furthermore, such as Figures 2 to 3 As shown, a rotating mechanism is installed on the slide rail 2 to remove the heat-sealing film 4 from the end of the sliding seat 23. The rotating mechanism includes a rotating plate 3, and a motor 21 is fixedly connected to the outer wall of the slide rail 2. The motor 21 is a high-torque, low-speed motor. A gear 22 is fixedly connected to the output shaft of the motor 21. A pair of rotating rods 32 are fixedly connected to the bottom outer wall of the rotating plate 3. A pair of support blocks 25 supporting the rotation of the rotating rods 32 are fixedly connected to the outer wall of the slide rail 2. One end of the rotating rod 32 is fixedly fitted with a gear sleeve 33 that meshes with the gear 22, and the end of the other rotating rod 32 is fixedly connected with a clamp 34 that locks the support block 25. The cooperation between the clamp 34 and the gear sleeve 33 ensures that the rotating plate 3 rotates in its original position.

[0027] Furthermore, such as Figures 3 to 4 As shown, a lifting mechanism installed on the rotating mechanism allows the heat-sealing film 4 to be disengaged from the top of the sliding seat 23. The lifting mechanism includes a telescopic groove 35 opened at the end of the rotating plate 3 away from the rotating rod 32. A cylinder 36 is fixedly connected inside the telescopic groove 35. A support block 5 is also slidably connected inside the telescopic groove 35. The piston rod of the cylinder 36 is fixedly connected to the support block 5. Support rods 51 are fixedly connected to both ends of the support block 5. A pair of U-shaped locking blocks 31 that lock the support block 5 and the support rods 51 are also fixedly connected to the end of the rotating plate 3 away from the rotating rod 32. A winding roller 52 for winding the heat-sealing film 4 is fixedly connected to both ends of the support rod 51. The inside of the heat-sealing film 4 can be easily removed from the winding roller 52. The end of the winding roller 52 away from the support rod 51 is fixedly connected to a retaining shaft 53. The top of the sliding seat 23 is provided with a retaining groove 24 for the retaining shaft 53 to be inserted. The pair of heat-sealing films 4, support rod 51, winding roller 52, retaining shaft 53 and support block 25 are all symmetrically arranged with the cylinder 36 as the center.

[0028] In this embodiment, when a food packaging heat-sealing film slitting machine is required, such as... Figure 1As shown, after the heat-seal film 4 is wound on the winding roller 52, only the air cylinder 36 in the telescopic groove 35 is started, the piston rod of the air cylinder 36 pushes the support block 5 to move, the support block 5 drives the support rod 51 at both ends to move, each support rod 51 drives the winding roller 52, the clamping shaft 53 and the heat-seal film 4 on the winding roller 52 to move in turn. Until the clamping shaft 53 is out of the clamping groove 24, the motor 21 on the outer wall of the slide rail 2 is started, the output shaft of the motor 21 drives the gear 22 to rotate, since the gear 22 and the gear sleeve 33 are meshed and connected, the gear 22 drives the gear sleeve 33 to rotate, the gear sleeve 33 drives the rotating plate 3 to rotate through the rotating rod 32, until the rotating plate 3 rotates to the state as shown, and a cart is placed at the position where the heat-seal film 4 is about to fall, until the heat-seal film 4 falls on the cart. Only the cart is easily pushed towards the clamping shaft 53 at the end of the heat-seal film 4, the heat-seal film 4 can be taken off from the state of lying on the winding roller 52, which is fast and labor-saving. When the rotating plate 3 needs to be repeatedly operated as described above, only the above operation is reversed, which is not described here. Figure 3
