[0023] When staff places the grain and oil packaging needing edge sealing on the upper surface of electric rotary lever 20, with the rotary movement of electric rotary lever 20 to the inside of extrusion plate 6, controller 23 controls the start of motor 2 at this time, and first bidirectional threaded rod 3 is rotated due to the rotation of the output shaft of motor 2, however, first fixed block 4 ensures the stability of the rotation of first bidirectional threaded rod 3 due to the screw connection between U-shaped internal thread block 5 and first bidirectional threaded rod 3, so that extrusion plate 6 is close to each other under the limiting action of limiting structure, and the position of packaging box is limited, when the inside surface of extrusion plate 6 is attached to the outer wall of packaging box, controller 23 controls the start of first air cylinder 7, so that the surface of inclined push block 8 slowly rises, and then L-shaped push block 18 is moved in the inside of sliding groove 17 by second air cylinder 19.

[0024] Wherein, the lower surface of edge sealing table 1 is fixedly connected with second fixed block 9, the inside of second fixed block 9 is rotatably connected with second bidirectional threaded rod 10, the surface of second bidirectional threaded rod 10 is screw-connected with internal thread plate 11, the upper surface of internal thread plate 11 is fixedly connected with guide plate 12, the inside of second fixed block 9 is fixedly connected with first limiting rod 13, the surface of first limiting rod 13 is movably connected with the inside of internal thread plate 11, and the front part of second bidirectional threaded rod 10 is fixedly connected with driving disc 14.

[0025] When staff needs to place grain and oil packaging box on the upper surface of electric rotary lever 20, driving disc 14 is rotated to drive second bidirectional threaded rod 10 to rotate in the inside of second fixed block 9, however, the surface of internal thread plate 11 is screw-connected with the surface of second bidirectional threaded rod 10, and the distance between front and rear internal thread plates 11 can be adjusted due to the limiting action of first limiting rod 13 to internal thread plate 11, staff places two packaging boxes needing edge sealing on the inside of guide plate 12, and packaging box is transported from right to left due to the rotation of electric rotary lever 20.

[0029] The sliding groove 17 provides space for the movement of the L-shaped pushing block 18, and the movement of the output shaft of the second air cylinder 19 drives the L-shaped pushing block 18 to push the packaging box cover inward, and finally the packaging box cover falls onto the upper part of the packaging box due to the gravity.

[0030] The inside of the edge sealing table 1 is fixedly installed with an electric rotating rod 20, the lower surface of the edge sealing table 1 is fixedly connected with a supporting frame 21, the supporting frame 21 penetrates through the upper part of the edge sealing table 1, and the upper part of the supporting frame 21 is fixedly connected with a gluing device 22.

[0031] The rotation of the electric rotating rod 20 realizes the transportation of the grain and oil packaging box from right to left, and the supporting frame 21 provides a point for the installation of the gluing device 22. The inside of the gluing device 22 is provided with a compacting structure and a glue supplying structure, which places the adhesive tape on the opening of the packaging box and presses the adhesive tape on the packaging box through the compacting structure.

[0032] The upper surface of the edge sealing table 1 is fixedly connected with a controller 23, and the controller 23 is electrically connected with the motor 2, the first air cylinder 7 and the second air cylinder 19.

[0033] The controller 23 can control the start of the motor 2, the first air cylinder 7 and the second air cylinder 19, thereby realizing the automatic sealing of the grain and oil packaging box.

[0034] There is a gap between the electric rotating rod 20, the inside of the electric rotating rod 20 is movably connected with the internal threaded plate 11, and the inside of the electric rotating rod 20 is movably connected with the U-shaped internal threaded block 5.

[0035] The internal threaded plate 11 and the U-shaped internal threaded block 5 are located in the gap of the electric rotating rod 20, and the forward and backward movement of the extrusion plate 6 or the guide plate 12 does not affect the rotation of the electric rotating rod 20.

[0036] The working principle and use process of the utility model:

[0037] When the staff places the grain and oil packaging that needs to be edge sealed on the upper surface of the electric rotating rod 20, the rotating movement of the electric rotating rod 20 is to the inner side of the extrusion plate 6, at this time, the controller 23 controls the starting of the motor 2, due to the rotation of the output shaft of the motor 2, the rotation of the first bidirectional threaded rod 3 is driven, however, due to the threaded connection between the U-shaped internal threaded block 5 and the first bidirectional threaded rod 3, the first fixed block 4 ensures the stability of the rotation of the first bidirectional threaded rod 3, so that the extrusion plate 6 is close to each other under the limiting action of the limiting structure, the position of the packaging box is limited, when the inner surface of the extrusion plate 6 is attached to the outer wall of the packaging box, the controller 23 controls the starting of the first air cylinder 7, so that the surface of the inclined push block 8 slowly rises, and then the L-shaped push block 18 is moved in the inside of the sliding groove 17 by the second air cylinder 19.

[0038] When the staff needs to place the grain and oil packaging box on the upper surface of the electric rotating rod 20, the second bidirectional threaded rod 10 is rotated in the inside of the second fixed block 9 by rotating the driving disc 14, however, due to the threaded connection between the surface of the internal threaded plate 11 and the surface of the second bidirectional threaded rod 10, and due to the limiting action of the first limiting rod 13 on the internal threaded plate 11, the distance between the front and rear internal threaded plates 11 can be adjusted, the staff places the two packaging boxes that need to be edge sealed on the inner side of the guide plate 12, and due to the rotation of the electric rotating rod 20, the packaging boxes are transported from right to left.

[0039] The third fixed block 15 provides the installation point of the second limiting rod 16, and due to the movable connection between the surface of the second limiting rod 16 and the inside of the U-shaped internal threaded block 5, the front and rear movement of the extrusion plate 6 is limited, avoiding the rotation of the extrusion plate 6 along the first bidirectional threaded rod 3 as the shaft.

[0040] The sliding groove 17 provides space for the movement of the L-shaped push block 18, and due to the movement of the output state of the second air cylinder 19, the L-shaped push block 18 pushes the packaging box cover inward, and finally due to the gravity of the packaging box cover, it falls on the upper part of the packaging box.

[0041] Through the rotation of the electric rotating rod 20, the grain and oil packaging box is transported from right to left, and the support frame 21 provides the installation point of the rubberizing device 22. The inside of the rubberizing device 22 is provided with a compacting structure and a glue supply structure, which places the adhesive tape on the opening of the packaging box, and presses the adhesive tape on the packaging box through the compacting structure.

[0042] Through the design of the controller 23, the controller 23 can control the starting of the motor 2, the first air cylinder 7 and the second air cylinder 19, so as to realize the automatic edge sealing of the grain and oil packaging box.

[0043] The front and back movement of the extrusion plate 6 or the guide plate 12 does not affect the rotation of the electric rotating lever 20 by locating the inner threaded plate 11 and the U-shaped inner threaded block 5 in the gap of the electric rotating lever 20.
