However, since the double-covered packing box of the present design is mainly referred to as a top-grade wine box, and is generally made of a relatively hard paper material, the present design chooses to fix the bottom cover 300 and the first inner sidewall of the box body 200 by adhesion for cost reasons. Based on this, the first inner side wall can be coated with the adhesive or the bottom cover 300 can be coated with the adhesive as in this embodiment, but because the box body 200 is arranged in a cylindrical structure with the sealed bottom end, the adhesive outlet device is extended into the inner cavity of the box body 200 for coating, so that the problems of inconvenience in gluing and easy pollution of the adhesive exist; in this embodiment, the bottom cover 300 is plate-shaped, and has the characteristics that the gluing area is easy to control and the gluing is convenient. The bottom cover 300 is longer and heavier than the top cover 400, so that the first inner sidewall of the cassette 200 is disposed below the second inner sidewall during the transportation of the cassette 200, and at this time, the bottom cover 300 is fixedly mounted on the first inner sidewall, and it is necessary to apply adhesive from the lower side of the bottom cover 300 to the lower surface of the bottom cover 300.

Step S22: lifting the bottom cover 300 to be positioned above the first inner sidewall of the case 200;

in this embodiment, the bottom cover mounting mechanism 4 first lifts the bottom cover 300 to be located above the first inner sidewall of the case 200, but not higher than the second inner sidewall of the case 200; of course, the bottom cover mounting mechanism 4 can also adjust the lateral position of the bottom cover 300, so that the bottom cover 300 is aligned with the open end of the case 200, thereby ensuring that the bottom cover 300 can smoothly enter the case 200 under the carrying of the bottom cover mounting mechanism 4, and avoiding interference with any inner sidewall of the case 200.

Step S23: transferring the bottom cover 300 into the magazine 200 entering the bottom cover assembling station 13;

in this embodiment, the bottom cover mounting mechanism 4 transfers the bottom cover 300 into the case 200 of the bottom cover assembling station 13, and stops after reaching a predetermined depth. The preset depth can be adjusted according to specific parameters of the dual-cap packing box, wherein, for example, in the dual-cap packing box, the length of the bottom cap 300 except the cover plate portion is equivalent to the length of the inner cavity of the box body 200, the distance from the opening end to the bottom wall of the inner cavity of the box body 200 is the preset depth, and the bottom cap mounting mechanism 4 stops the continuous transfer when the bottom cap 300 is transferred to a position that the bottom end of the bottom cap 300 abuts against the bottom wall of the inner cavity of the box body 200; in one double-lid packing box, when the length of the bottom lid 300 excluding the cover plate portion is half of the length of the inner cavity of the box body 200, the distance from the opening end to the middle of the inner cavity of the box body 200 is the preset depth, and the bottom lid mounting mechanism 4 transfers the bottom lid 300 to the bottom end of the bottom lid 300 to reach the middle of the inner cavity of the box body 200, that is, stops transferring.

Step S24: the bottom cover 300 is pressed down to be adhesively fixed to the first inner sidewall of the case 200.

In this embodiment, the above steps can ensure that the bottom cover 300 is located at the position over the first inner sidewall, and then the bottom cover mounting mechanism 4 operates the bottom cover 300 to press down to abut against the first inner sidewall of the box 200, and continues to apply a downward force to ensure that the bottom surface of the bottom cover 300 and the first inner sidewall are tightly adhered, so as to complete the mounting operation of the bottom cover 300 in the box 200.

Further, referring to fig. 3 in combination with fig. 15, 16 and 18, in a third embodiment of the assembling method of the dual-lid packing box of the present invention, the step S40 includes:

step S41: coating an adhesive on the upper surface of the top cover 400;

in this embodiment, similarly to the bottom cover 300, based on the consideration of reducing the economic cost and simultaneously ensuring that the top cover 400 can be firmly mounted to the second inner sidewall of the case 200, the upper surface of the top cover 400 can be coated with the adhesive instead of the second inner sidewall, which has the advantages of convenient coating and intuitive coating process. The adhesive coating operation of the top cover 400 and the adhesive coating operation of the bottom cover 300 may be substantially the same, except that the adhesive discharging direction of the adhesive discharging device is different. Specifically, the glue discharging device may include a first glue spraying device 44 for gluing the bottom cover 300 and a second glue spraying device 53 for gluing the top cover 400, wherein the glue discharging surface of the first glue spraying device 44 is arranged upward, and the glue discharging surface of the second glue spraying device 53 is arranged downward.

Step S43: air-drying the adhesive coating position of the top cover 400;

it should be noted that, in the present embodiment, the air drying device 54 is used to air dry the adhesive coating portion of the top cover 400, but the air drying degree of the adhesive is not limited. To the different grade type the viscose, its bonding effect is not strictly in direct proportion with humidity to, the activity of the component of part viscose reaches the highest under certain dry humidity proportion, consequently, can be according to specific application requirement, to the air-dry processing is carried out to the viscose coating department of top cap 400, through adjusting the dry humidity of viscose makes the bonding effect of viscose roughly reaches the best.

Step S44: moving the caps 400 into the magazine 200 at the cap assembly station 14;

in this embodiment, the position of the top cover 400 operated by the top cover installation mechanism 5 is slightly lower than the height of the second inner sidewall of the box body 200, and the relative position between the top cover 400 and the box body 200 is adjusted, so that the top cover 400 is aligned with the open end of the box body 200, and then the top cover 400 is transferred into the box body 200 at the top cover assembly station 14. Similarly to the bottom cover 300, the top cover installation mechanism 5 stops continuing moving after the top cover 400 extends into the box body 200 to a preset depth, and the preset depth can be adjusted according to the specific parameters of the double-cover packaging box, which is not described herein again.

Step S45: the top cover 400 is lifted and adhesively fixed to the second inner sidewall of the case 200.

In this embodiment, after the operation is completed, the top cover 400 is located at a position right below the second inner sidewall, and the top cover mounting mechanism 5 operates the top cover 400 to move towards the second inner sidewall to abut against the second inner sidewall, and then continues to press upwards to ensure a tight fit between the top cover 400 and the second inner sidewall.

Further, referring to fig. 4, in a fourth embodiment of the assembling method of the double-lid packaging box according to the present invention, after the step S41 and before the step S43, the assembling method further includes:

step S42: the top cover 400 is rolled.
