Then, the outer ends of the two second pulling ropes are connected to both sides of the electric telescopic rod through guide wheels. When the electric telescopic rod drives the working plate to descend, it can pull the two turntables to drive the cooling fans to quickly dissipate heat and cool down. Subsequently, the elastic forces of the two torsion springs can be used to elastically reset the two rotated cooling fans, with better practicability. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] The present utility model provides the following technical solutions:

[0030] In the first embodiment, in order to solve the problem that the existing carton mouth-packing machine cannot automatically eject the cartons after processing during the mouth-packing and sealing of cartons, resulting in very time-consuming and laborious taking of cartons, it is disclosed that:

[0031] A fuselage 1, on the front side of the bottom of which two closing doors 2 are hinge-mounted, and on the top of the fuselage 1, a mounting rack 3 is screw-mounted, and a processing seat 6 is screw-mounted on the top of the fuselage 1;

[0032] It further includes: an electric telescopic rod 4, the electric telescopic rod 4 is screw-mounted on the inner side of the top of the mounting rack 3, and at the bottom of the electric telescopic rod 4 is provided a working plate 5, and corresponding to the bottom of the working plate 5 is a placement plate 13. The placement plate 13 is slidably mounted inside the processing seat 6 through two tension springs 14, and the two tension springs 14 have the same structure, and a carton is placed above the placement plate 13.

[0033] The processing base 6 has grooves at both inner ends that penetrate through and slidably mount the transmission rods 11. The two transmission rods 11 are symmetrically arranged with respect to the vertical center line of the processing base 6. The inner ends of the two transmission rods 11 penetrate and extend to both sides inside the processing base 6. At the same time, the upper parts of the inner ends of the two transmission rods 11 correspond to both sides of the bottom of the placement plate 13. The outer ends of the two transmission rods 11 are both connected to the first pull ropes 7. The outer ends of the two first pull ropes 7 are both connected to both sides of the electric telescopic rod 4 through guide wheels. At the same time, the structures of the two first pull ropes 7 are the same.

[0034] Reset springs 12 are wound and connected to the outer sides of the two transmission rods 11. The outer sides of the two reset springs 12 are connected to the processing base 6. Moreover, the two reset springs 12 are both arranged at both inner ends inside the processing base 6. Second magnets 16 are screwed to the upper parts of the inner ends of the two transmission rods 11. First magnets 15 correspond to the upper parts of the two second magnets 16. And the two first magnets 15 are screwed to both sides of the bottom of the placement plate 13.

[0035] As Figures 1 - 5 shown, when it is necessary to perform mouth wrapping and sealing on the paper box, place the paper box on the placement plate 13, and then start the electric telescopic rod 4 to drive the working plate 5 to perform mouth wrapping and sealing on the paper box on the placement plate 13. While the electric telescopic rod 4 drives the working plate 5 to descend, it will drive the two first pull ropes 7 to pull the two transmission rods 11 to extend and move through the guide wheels, avoiding the descending placement plate 13 being affected by the two transmission rods 11 during the later mouth wrapping and sealing;

[0036] After the mouth wrapping machine finishes mouth wrapping and sealing, the two reset springs 12 will elastically reset the two pulled and extended transmission rods 11 through their own elastic forces. At this time, the two transmission rods 11 will squeeze and lift the placement plate 13 through the principle of magnetic field repulsion between the two second magnets 16 and the first magnets 15 arranged at both ends of the bottom of the placement plate 13. Because the elastic force of the reset spring 12 is greater than the elastic force of the tension spring 14, the automatic ejection of the paper box on the placement plate 13 can be realized subsequently, making the operation more time-saving and labor-saving.

[0037] Embodiment 2, different from Embodiment 1, can quickly dissipate heat and cool the paper box after mouth wrapping and sealing, which may cause the phenomenon that the paper box after processing is too hot to scald the staff. It discloses:

[0038] The mounting bracket 3 has turntables 9 rotatably installed on both sides of its top. Both of the two turntables 9 are inclined, and both of the two turntables 9 are rotatably installed with cooling fans 10 through drive motors. At the same time, the bottom ends of the two turntables 9 are both connected with second pull ropes 8, and the outer ends of the two second pull ropes 8 are both connected to both sides of the electric telescopic rod 4 through guide wheels. The output ends of the two turntables 9 are both wound and connected with torsion springs 17, and the two torsion springs 17 have the same structure. The outer ends of the two torsion springs 17 are both connected to both sides of the inner wall of the mounting bracket 3.

[0039] As Figures 1 - 6 shown, when the electric telescopic rod 4 drives the working plate 5 to descend in position, it will also drive the two second pull ropes 8 to pull the two turntables 9 to turn in position through the guide wheels. Subsequently, the two turntables 9 will drive the two cooling fans 10 to perform heat dissipation drive through the drive motors, expanding the heat dissipation range of the two cooling fans 10, and better quickly cooling and dissipating heat from the paper boxes after the bag mouths are sealed. Finally, the elastic reset of the positions of the two turntables 9 after swinging can be achieved by using the elastic force of the two torsion springs 17, which is more convenient for later bag mouth sealing of the paper boxes, and the practicability is better.

[0040] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
