[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-6 As shown, a disposable lunch box crimping sealing device includes a support base 1, a box cover 10 and a box body 11. A carrier plate 2 is provided on the top of the support base 1, and a through slot 9 is provided on the carrier plate 2. Linear guide rails 5 are symmetrically provided at the corresponding positions of the edges of the top of the support base 1 and the through slot 9 on both sides. The carrier plate 2 is movably connected to the linear guide rails 5, and the two ends of the carrier plate 2 are symmetrically embedded with a lower mold 4 for fixing the box body 11. A bracket 3 is provided at one end of the top of the support base 1, and a handle 12 is provided at the upper end of the bracket 3. One end of the handle 12 is rotatably connected to one side of the upper end of the bracket 3 through a pin shaft. A convex seat 15 is provided on the side of the bracket 3 close to the carrier plate 2, and a column 13 is vertically movably connected to the convex seat 15. The upper end of the column 13 is arc-shaped and corresponds to one end of the handle 12. A convex shaft 1 is fixedly provided on one side of the column 13 7. A spring 14 is sleeved on the outer side of the column 13, and the spring 14 is located between the convex shaft 17 and the convex seat 15, so that the convex shaft 17 compresses the spring 14 when the column 13 descends. The bottom of the column 13 is provided with an upper mold 6 corresponding to the lower mold 4 and used to press down the box cover 10. The bottom of the upper mold 6 is provided with a groove adapted to the box cover 10, and the lower end outer edge of the upper mold 6 corresponds to the outer edge of the box cover 10. One end of the top of the support seat 1 is provided with a cylinder 7 for driving the displacement of the carrier plate 2, and one side of the carrier plate 2 is provided with a connecting block 8 corresponding to the cylinder 7. The cylinder 7 is fixedly set on the top of the support seat 1, and the end of the output shaft of the cylinder 7 is connected to the connecting block 8. The inner side of the upper end of the lower mold 4 is provided with a curling groove 16. The inner cavity of the curling groove 16 is a "U"-shaped structure, and the curling groove 16 corresponds to the outer edge of the box cover 10.

[0024] When in use, the box body 11 is placed in one of the lower molds 4, and the outer edge of the upper end of the box body 11 corresponds to the curling groove 16. The box cover 10 is placed on the top of the box body 11, and the outer edge of the box cover 10 corresponds to the outer edge of the upper end of the box body 11. Then the cylinder 7 drives the carrier plate 2 to move, so that the box cover 10 moves to the bottom of the upper mold 6, and then the handle 12 is pressed down. The handle 12 drives the column 13 to move down, and the column 13 drives the convex shaft 17 to compress the spring 14, so that the column 13 drives the upper mold 6 to move down to the box cover 10, and the box cover 10 is pressed down. The outer edge of the box cover 10 enters the curling groove 16. When under pressure, it can be guided to curl up by itself under the arc structure inside the curling groove 16, and then curled to the outer edge of the box body 11 to achieve curling and sealing. After completion, the handle 12 is released, the upper mold 6 is reset, and the cylinder 7 drives the carrier plate 2 to be recovered, and the curled product is removed. During the processing, a loading operation can be performed on a lower mold 4 next to it. In this way, the positions of the two lower molds 4 are exchanged after curling, and the product on the other lower mold 4 can be curled and sealed during loading and unloading, which improves production continuity, greatly improves work efficiency, and facilitates product removal.
