Example 1

As shown in fig. 1-2, the present invention provides a carton sleeve flexible guiding device, which comprises a bracket 3 and guiding rollers 4 positioned around the bracket 3, wherein the bracket 3 comprises a guiding rod 31 positioned at the upper part of the bracket 3 and a guiding plate 32 positioned at the lower part of the bracket 3, the guiding rod 31 is in a gradually expanding cone shape with a small upper part and a large lower part, and is used for guiding when the outer box 1 moves downwards, the upper end of the guiding rod 31 is connected to the bracket 3 through a bolt, and the inclination angle of the guiding rod 31 can be adjusted through a tightening bolt. The guide plate 32 is in a gradually-expanding conical shape with a large upper part and a small lower part and is used for guiding when the device is placed into the inner box 2, the lower end of the guide plate 32 is fixed on the bracket 3 through bolts, and the inclination angle of the guide plate 4 can be adjusted through tightening and loosening bolts. The guide roller 4 is used for expanding the opening of the outer box 1, so that the interference of the edges of the inner box and the outer box is avoided. An elastic guide mechanism is arranged between every two adjacent guide rollers 4, and under the non-use state, the four elastic guide mechanisms are respectively positioned above the four top angles of the inner box 2 and are positioned outside the inner box 2. In this embodiment, the elastic guiding mechanism is a guiding wheel 51, and the guiding wheel 51 is fixedly connected with the bracket 3 through an elastic mounting frame 512. The elastic mounting frame 512 includes two elastic members 5121 oppositely disposed, and the guide wheel 51 is connected between the two elastic members 5121 through the guide shaft 513. The elastic member 5121 performs a telescopic resilient function of the guide wheel 51. Specifically, during the use, arrange this flexible guider inside inner box 2 in, the outer container is from directly over this flexible guider down the cover, when the base angle of outer container 1 contacts leading wheel 51, leading wheel 51 rolls under the effect of outer container 1, receive the extrusion of 1 base angle of outer container simultaneously, under the effect of elastic component 5121, leading wheel 51 can outwards kick-back, make 1 base angle of outer container enlarge, guide roll 4 is followed outward to outer container 1 and is carried out the flaring simultaneously, make the outer container change and embolia inner box 2. The setting of leading wheel 51 and elasticity mounting bracket 512 has avoided the interference of outer container 1 base angle and 2 apex angles of inner box on the one hand, damages when avoiding the carton pouring jacket, has reduced the resistance that pouring jacket in-process outer container 1 received simultaneously, reduces the pouring jacket degree of difficulty. In addition, the elastic design is adopted, the self-adaptive capacity of the device is improved, and the requirements of the carton sleeve box are met.

Example 2

As shown in fig. 3-5, the present embodiment provides a flexible guiding device for carton sleeve, wherein the flexible guiding mechanism is a smooth-surfaced flexible guiding plate 52, the flexible guiding plate 52 is fixedly connected to the bracket 3 through a mounting bracket 521, a pressing plate 522 is disposed at a contact position between the flexible guiding plate 52 and the mounting bracket 521, and the pressing plate 522 plays a role in fixing and pressing the flexible guiding plate 52. The elastic guide plate 52 is provided with the flexible elastic return sheet 3, preferably arranged at the bottom of the elastic guide plate 52, and the elastic guide plate 52 is supported and reset, so that the elastic return force of the elastic guide plate 52 can be increased, and the angle expansion capability of the elastic guide plate 52 is enhanced. One end of the elastic guide plate 52, which is far away from the mounting frame 521, is provided with a V-shaped opening, and the elastic guide plate 52 is extruded in the downward moving process of the outer box 1, so that the vertex angle of the inner box 2 can be better attached by the elastic guide plate 52, and the vertex angle of the inner box 2 can be effectively protected while the vertex angle is expanded. In the non-use state, the elastic guide plate 2 may be inclined upward, horizontal or inclined downward, preferably inclined downward, and the upper surface of the elastic guide plate 52 is smooth, which can reduce the resistance in the casing of the outer case 1. In addition, because old carton all has the use vestige, the aspect such as hardness is not like new carton, changes the damage, and the pouring jacket degree of difficulty is great, and this carton pouring jacket flexible guiding device can effectively protect the carton, reduces the pouring jacket degree of difficulty for this guider also is applicable to old carton pouring jacket, has better suitability.

Specifically, during the use, the pouring jacket down of outer container 1, when outer container 1 contacts elastic guide plate 52, extrusion elastic guide plate 52, make elastic guide plate 52 warp laminating inner box 2 four corners, elastic guide plate 5 presss from both sides between outer container 1 and inner box 2 this moment, under the effect of resilience force, strut 1 base angle of outer container, and simultaneously, glossy elastic guide plate 52 can enough protect inner box 2, can reduce the resistance when outer container 1 overlaps again, make outer container 1 change and embolia inner box 2, reduce the pouring jacket degree of difficulty.

The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
