[0019] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. See Figures 1-6 As shown, an automatic sealing machine with a limiting function includes a base 1, a sealing box 2 fixedly mounted on the surface of the base 1, a sealing cavity 3 formed in the side wall of the sealing box 2, a sealing plate 4 slidably connected to the inner wall of the sealing cavity 3, a heating rod 5 fixedly mounted on the bottom surface of the sealing plate 4, a lifting cylinder 6 fixedly mounted on the surface of the sealing box 2, a lifting rod 7 fixedly connected to the output end of the lifting cylinder 6, one end of the lifting rod 7 extending into the interior of the sealing cavity 3 and fixedly connected to the surface of the sealing plate 4, a limiting plate 8 slidably connected to the inner wall of the sealing cavity 3, an adjustment device provided on one side of the limiting plate 8, an electrical box 22 fixedly mounted on the side wall of the sealing box 2, an operation control panel 23 fixedly mounted on the surface of the sealing box 2, the operation control panel 23 being wired to the electrical box 22, the lifting cylinder 6 being wired to the control panel 23, and the heating rod 5 being wired to the operation control panel 23.

[0020] When sealing the opening of a food bag in a film bag, the opening of the bag can be placed into the sealing cavity 3. At this time, the side wall of the bag opening will abut against the side wall of the limiting plate 8. The limiting plate 8 can provide a limiting function to keep the opening of the bag in a flush position. Then, the lifting cylinder 6 can be activated by the cooperation of the electrical box 22 and the operating control panel 23. The lifting cylinder 6 will drive the lifting rod 7 to move down. The moving lifting rod 7 will push the sealing plate 4 down, and the sealing plate 4 will push the heating rod 5 down to seal the bag below the heating rod 5. This can ensure that the sealing opening of the bag will not be crooked and improve the aesthetics of the sealing.

[0021] See Figure 2 As shown, the adjustment device includes an adjustment groove 9 formed on the bottom surface of the plastic sealing cavity 3, and an adjustment screw 10 is rotatably connected to the inner wall of the adjustment groove 9. An adjustment sleeve 11 is threadedly connected to the side wall of the adjustment screw 10, and the top end of the adjustment sleeve 11 is fixedly connected to the bottom surface of the limiting plate 8. One end of the adjustment screw 10 extends out of the adjustment groove 9 and is fixedly connected to an adjustment nut 12.

[0022] Furthermore, depending on the usage requirements, the adjusting nut 12 can be rotated, which will drive the adjusting screw 10 to rotate, causing the adjusting sleeve 11 connected to the adjusting screw 10 to move along the adjusting groove 9. In turn, the adjusting groove 9 will drive the limiting plate 8 to move, adjusting the position of the limiting plate 8, and then adjusting the position of the sealing opening and the bag opening when the heating rod 5 performs the sealing work, improving the convenience of use and making it simple and effective.

[0023] See Figure 3 and Figure 4As shown, the side wall of the adjusting nut 12 has multiple strip grooves 13.

[0024] By setting the groove 13, the roughness of the side wall of the adjusting nut 12 is increased, the friction is increased, and the groove 13 is easier to rotate.

[0025] See Figure 5 As shown, the side wall of the sealing cavity 3 is provided with a support groove 14, and the inner wall of the support groove 14 is fixedly connected with a support rod 21. The side wall of the support rod 21 is slidably connected with a support sleeve 15, and the side wall of the support sleeve 15 is fixedly connected with the side wall of the limiting plate 8.

[0026] When the limiting plate 8 moves, the limiting plate 8 will drive the support sleeve 15 to slide along the support slide rod 21 inside the support slide groove 14. The cooperation between the support slide rod 21 and the support sleeve 15 can provide a certain limiting support effect and improve the stability of use.

[0027] See Figure 5 As shown, two auxiliary platforms 16 are fixedly connected to the surface of the base 1; By setting up an auxiliary platform 16, a support position can be provided to support the packaging bag, making it easier to slide the bag opening into the sealing cavity 3 and improving the ease of operation.

[0028] See Figure 4 As shown, the side wall of the auxiliary platform 16 is provided with multiple auxiliary slide grooves 17, and the inner wall of the auxiliary slide groove 17 is slidably connected to an auxiliary slide rod 18. One end of the auxiliary slide rod 18 extends out of the auxiliary slide groove 17 and is fixedly connected to an extension platform 19, and the side wall of the extension platform 19 is fixedly connected to a connecting rod 20.

[0029] The connecting rod 20 drives the two extension platforms 19 to pull the auxiliary slide bar 18 outward along the auxiliary slide groove 17, thereby extending the length of the auxiliary position formed by the auxiliary platform 16, which can easily adapt to packaging bags of different sizes and improve the ease of operation.

[0030] When performing plastic sealing on food packaged in film bags, the opening of the packaging bag can be placed into the sealing cavity 3. At this time, the side wall of the opening of the packaging bag will abut against the side wall of the limiting plate 8. The limiting plate 8 can provide a limiting function to keep the opening of the packaging bag in a flush position. Then, the lifting cylinder 6 can be activated by the cooperation of the electrical box 22 and the operating control panel 23. The lifting cylinder 6 will drive the lifting rod 7 to move down. The moving lifting rod 7 will push the sealing plate 4 down, and the sealing plate 4 will push the heating rod 5 down to perform plastic sealing on the packaging bag below the heating rod 5. This can ensure that the sealing opening of the packaging bag will not be crooked and improve the aesthetics of the sealing.

[0031] Furthermore, depending on the usage requirements, the adjusting nut 12 can be rotated, which will drive the adjusting screw 10 to rotate, causing the adjusting sleeve 11 connected to the adjusting screw 10 to move along the adjusting groove 9. In turn, the adjusting groove 9 will drive the limiting plate 8 to move, adjusting the position of the limiting plate 8, and then adjusting the position of the sealing opening and the bag opening when the heating rod 5 performs the sealing work, improving the convenience of use and making it simple and effective.
