DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 , the utility model provides a technical solution: a food packaging box sealing assembly, comprising a fixing seat 1, which is arranged in a rectangular structure and is used for fixing the entire assembly;

[0030] A sealing mechanism 2, which is arranged at the middle position of the top of the fixing base 1 and is used for sealing the food packaging box 5;

[0031] The moving mechanism 3 is arranged at both ends of the top of the fixing base 1 and is used for moving the sealing mechanism 2;

[0032] Also includes:

[0033] A placement slot 4 is symmetrically arranged above the fixing seat 1, a packaging box 5 is arranged above the placement slot 4, and an ejection mechanism 6 is arranged below the placement slot 4;

[0034] The ejection mechanism 6 is arranged inside the reserved groove 7, and the reserved groove 7 is arranged inside the fixing seat 1.

[0035] The present application provides a packaging box sealing assembly with an ejection mechanism 6. Specifically, when using it, first, the packaging box 5 to be packaged needs to be placed inside the placement slot 4, and then the cover plate to be sealed is placed on the top of the packaging box 5. Then, the sealing mechanism 2 is driven by the moving mechanism 3 to move its position. When the sealing mechanism 2 reaches the top of the placement slot 4, it is necessary to start the sealing mechanism 2 to descend and seal the packaging box 5 in the placement slot 4. After the sealing is completed, the sealing mechanism 2 is controlled to move upward. After that, the ejection mechanism 6 inside the reserved slot 7 will eject the sealed packaging box 5 out of the placement slot 4, so that the sealed packaging box 5 can be taken out.

[0036] Among them, according to Figure 2-3 As shown, the sealing mechanism 2 includes:

[0037] The fixing frame 21 has a U-shaped cross section;

[0038] The telescopic cylinder 22 is arranged at the middle position of the top end of the fixed frame 21. A pushing mechanism 23 is connected to the bottom of the telescopic cylinder 22. The pushing mechanism 23 includes a pushing plate 231 and a hot pressing sealing member 232. The pushing plate 231 is arranged at the bottom of the telescopic cylinder 22, and a hot pressing sealing member 232 is arranged in the middle of the pushing plate 231. The position of the hot pressing sealing member 232 corresponds to the position of the placement groove 4.

[0039] The sealing mechanism 2 also includes:

[0040] Two connecting rods 24 are fixed at the bottom of the push plate 231, and the positions of the connecting rods 24 correspond to the positions of the reserved grooves 7;

[0041] Specifically, when sealing, it is necessary to start the telescopic cylinder 22 at the top of the fixed frame 21, so that its top drives the push plate 231 to descend and drives the hot-pressing sealing member 232 and the connecting rod 24 to descend together. When the hot-pressing sealing member 232 descends, it will perform heat-seal work between the cover plate on the packaging box 5 and the packaging box 5 to achieve the sealing effect.

[0042] Further, according to Figure 3 As shown, the moving mechanism 3 is provided with two, and it comprises:

[0043] The servo motor 31 is arranged outside the fixing base 1, and the top end of the servo motor 31 is coaxially connected with a screw rod 32, the external thread of the screw rod 32 is connected with a rotating sleeve 33, and the top end of the rotating sleeve 33 is integrally installed with the bottom of the fixing frame 21;

[0044] Specifically, when controlling the movement of the entire fixed frame 21, it is necessary to start the servo motor 31 so that it drives the screw rod 32 at its top to rotate. When the screw rod 32 rotates, it will be threadedly connected with the rotating sleeve 33, so that the rotating sleeve 33 will drive the fixed frame 21 to move outside the screw rod 32, thereby completing the movement of the entire sealing mechanism 2.

[0045] In this application, according to Figure 2 and Figure 4 As shown, an ejection mechanism 6 is provided at the bottom of the reserved groove 7, and the ejection mechanism 6 includes:

[0046] Push rods 61, two of which are arranged inside the placement slot 4, and the bottom of which passes through the placement slot 4 and is connected to the moving plate 62;

[0047] The bottom of the moving plate 62 is connected to the bottom of the reserved groove 7 via a return spring 63 .

[0048] The top ends of both sides of the movable plate 62 correspond to the connecting rod 24, and the movable plate 62 is controlled by the connecting rod 24 to perform the descending operation;

[0049] Specifically, when the pushing plate 231 descends, it drives the connecting rod 24 to descend. When the connecting rod 24 descends, its top end will press down the moving plate 62, so that the moving plate 62 descends and drives the pushing rod 61 at its top end to descend. When the pushing rod 61 descends, the packaging box 5 containing food in the placement groove 4 will slowly and steadily descend, thereby ensuring that the entire packaging box 5 can be completely inside the placement groove 4, thereby heat sealing can be carried out. After the heat sealing is completed, when the entire pushing plate 231 drives the connecting rod 24 to rise, the moving plate 62 at this time will reset upward under the action of the reset spring 63. Therefore, when resetting, the pushing rod 61 will also move upward. Therefore, under the action of the pushing rod 61, the heat-sealed packaging box 5 can be ejected from the inside of the placement groove 4, thereby facilitating the subsequent taking. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.
