A cutting groove 10 is provided on the lower surface of the installation box 4. A driving screw 9 is fixedly connected to the front of the installation box 4. The output end of the driving motor 5 passes through the mounting box 4 and is fixedly connected to the lead screw 7. The inner wall of the mounting box 4 is fixedly connected to the guide rod 23. The surface of the mounting frame 6 is fixedly connected to the ear plate 24 which is slidably connected to the guide rod 23. The upper surface of the workbench 1 is inlaid with a cutting mat 11. The position of the cutting mat 11 is adapted to the circular cutter 9. The lower surface of the workbench 1 is fixedly connected to the first heat sealing plate 12. The lower surface of the workbench 1 is fixedly connected to the second heat sealing plate 13. The upper surface of the workbench 1 is inlaid with a matching plate 14. The matching plate 1 4, and the positions of the two matching plates 14 are adapted to the first heat sealing plate 12 and the second heat sealing plate 13. First, one end of the packaging bag is placed under the first heat sealing plate 12, and the electric push rod 2 is retracted to move the installation box 2 downward, and one end of the packaging bag is sealed by the first heat sealing plate 12. The bread is placed in the packaging bag so that it is located at the sealed position of the packaging bag. One end of the packaging bag is placed under the installation box 4, and the electric push rod 2 is controlled to retract to drive the installation box 4 to move downward so that the first heat sealing plate 12 and the second heat sealing plate 13 fix the packaging bag. At the same time, the first heat sealing plate 12 and the second heat sealing plate 13 are heated to seal the packaging bag. At the same time, the circular cutter 9 is inserted into the cutting pad 11, and the driving motor 5 is started again. The driving motor 5 drives the lead screw 7 to rotate, and then the lead screw 7 and the threaded sleeve 8 rotate relative to each other, driving the mounting frame 6 to move back and forth, and the packaging bag is cut by the circular cutter 9. After the cutting is completed, the electric push rod 2 is controlled to retract to move the installation box 4 upward, and the packaged bread is taken out. At this time, one end of the remaining packaging bag is sealed.

[0027] In this embodiment, if Figure 1 、 Figure 2 and Figure 5As shown, the inner wall of the installation box 4 is fixedly connected with a bolt sleeve 15, and the upper surface of the installation box 4 is detachably connected with the upper cover 16 through the cooperation of the bolt sleeve 15 and the bolt. The upper surface of the upper cover 16 is provided with a sliding groove 17, and the inner wall of the installation box 4 is fixedly connected with a mounting plate 20, and the upper surface of the mounting plate 20 is fixedly connected with a mounting tube 18. A spring 19 is provided inside the mounting tube 18, and the inner wall of the sliding groove 17 is slidably connected with a connecting rod 21.

The inner wall of the mounting tube 18 is slidably connected to the pressing plate 22, and the installation box 4 moves downward. After the first heat sealing plate 12 and the second heat sealing plate 13 are both tightly attached to the matching plate 14, the mounting plate 20 and the mounting tube 18 will slide, and the compression spring 19 will produce a buffer to prevent excessive pressure. The upper cover 16 is detachable, and the installation box 4 can be removed, and then the interior of the installation box 4 can be inspected.

[0028] In this embodiment, if Figures 1-6 As shown, the working principle of a bread packaging and sealing machine provided in this embodiment is as follows:

[0029] When sealing the unsealed long packaging bag, the electric push rod 2 contracts, causing the installation box 2 to move down, and one end of the packaging bag is sealed by the first heat sealing plate 12. The bread is placed in the packaging bag so that it is located at the sealed position of the packaging bag. One end of the packaging bag is placed under the installation box 4, and the electric push rod 2 is controlled to contract, driving the installation box 4 to move down, so that the first heat sealing plate 12 and the second heat sealing plate 13 fix the packaging bag. At the same time, the first heat sealing plate 12 and the second heat sealing plate 13 are heated to seal the packaging bag. At the same time, the circular cutter 9 is inserted into the cutting pad 11, and the driving motor 5 is started again. The driving motor 5 drives the lead screw 7 to rotate, and then the lead screw 7 and the threaded sleeve 8 rotate relative to each other, driving the installation frame 6 to move back and forth, and the packaging bag is cut by the circular cutter 9. After the cutting is completed, the electric push rod 2 is controlled to contract, causing the installation box 4 to move up, and the packaged bread is taken out. At this time, one end of the remaining packaging bag is sealed;

[0030] When sealing a single-sealed short packaging bag, bread is placed in the packaging bag, the electric push rod 2 contracts, causing the installation box 2 to move downward, and the unsealed portion of the packaging bag is sealed by the first heat-sealing plate 12;

[0031] When sealing an unsealed short packaging bag, put the bread into the packaging bag, the electric push rod 2 contracts, causing the installation box 2 to move down, and the unsealed part of the packaging bag is sealed by the first heat sealing plate 12, and then the other opening is sealed according to the above process.

[0032] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
