DETAILED DESCRIPTION

[0028] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model and cannot be understood as limiting the utility model.

[0029] The following disclosure provides many different embodiments or examples for implementing different aspects of the utility model.

[0030] Referring to Figs. 1 to 4 As shown in FIG. 1, a paperboard conveying device of a boxing machine comprises a conveying belt 1, a storage rack 2 and a limiting frame 3, the storage rack 2 is provided with a placing plate 21, the placing plate 21 is butted against the conveying belt 1, the placing plate 21 is inclined downward along the direction away from the conveying belt 1, one end of the placing plate 21 away from the conveying belt 1 is provided with a stop block 22, and the stop block 22 can be elastically swung;

[0031] The limiting frame 3 comprises a limiting plate 31, the limiting plate 31 is arranged opposite to the placing plate 21, and a limiting passage is formed between the placing plate 21 and the limiting plate 31;

[0032] The conveying belt 1 is responsible for transporting the paperboard, and after the paperboard reaches the material placing plate 21, it enters the limiting channel and can be stacked on the stop block 22. Since the stop block 22 can be elastically swung, when the suction cup sucks the paperboard, the paperboard will push the stop block 22 to swing, until the paperboard is sucked out, and then the stop block 22 will quickly reset to continue blocking the paperboard. In this way, it can be ensured that only one paperboard is sucked out each time, and the remaining paperboards will not fall off.

[0033] In this embodiment, the storage rack 2 has a notch 23 at the end away from the conveying belt 1, and the material placing plate 21 cooperates with the notch 23 to form a groove, and a rotating shaft 24 is arranged in the groove. The rotating shaft 24 is provided with a mounting frame 25, and the mounting frame 25 is rotatable. The groove can hide the rotating shaft 24 and the mounting frame 25, so as to avoid affecting the sucking out of the paperboard;

[0034] The rotating axis of the mounting frame 25 is in the horizontal direction and perpendicular to the stacking direction of the paperboard. A torsional spring is sleeved on the rotating shaft 24, and the mounting frame 25 is connected with the torsional spring to realize elastic swinging. The stop block 22 is fixed on the mounting frame 25.

[0035] The mounting frame 25 is connected with one force arm of the torsional spring, and the other force arm of the torsional spring is in contact with the inner wall of the notch 23. In this way, when the paperboard swings the stop block 22, the stop block 22 will rotate the mounting frame 25 to twist the torsional spring. After the paperboard is sucked out, the torsional spring resets the mounting frame 25, so as to reset the stop block 22.

[0036] In this embodiment, the stop block 22 can adjust the position along the axial direction of the rotating shaft 24, so that the stop block 22 can be against the paperboard. Moreover, the stop block 22 is two or more, which has better stability when stopping the paperboard.

[0037] Specifically, the mounting frame 25 is provided with a long waist hole extending along the axial direction of the rotating shaft 24. The stop block 22 is fixed on the mounting frame 25 by a bolt passing through the long waist hole. When the position needs to be adjusted, the bolt can be loosened, the stop block 22 can be moved along the long waist hole, and after the position is adjusted, the bolt is tightened.

[0038] Moreover, the mounting frame 25 is provided with a plurality of long waist holes, and the stop block 22 can be installed on any long waist hole according to actual needs.

[0039] In this embodiment, the material placing plate 21 extends out a plurality of protrusions 211 at the end away from the conveying belt 1. The plurality of protrusions 211 are arranged at intervals, and the stop block 22 is located between two protrusions 211.

[0040] After the paperboard is sucked out, the rear paperboard will not directly fall off from the material placing plate 21 due to the existence of the protrusions 211, but will move along the protrusions 211, so that the stop block 22 has enough time to reset.

[0041] In the embodiment, the positioning block 26 is arranged on the material placing plate 21 and used to block one end of the paperboard along the axial direction of the rotating shaft 24; the positioning block 26 can be adjusted along the axial direction of the rotating shaft 24;

[0042] Further, the mounting rod 32 is arranged, the length direction of the mounting rod 32 is parallel to the axial direction of the rotating shaft 24, and the limiting plate 31 is arranged on the mounting rod 32;

[0043] The mounting rod 32 is provided with the positioning plate 33, the positioning plate 33 cooperates with the positioning block 26 to limit the paperboard from moving along the axial direction of the rotating shaft 24, and the paperboard is stacked on the blocking block 22 in a preset posture after being limited by the limiting plate 31.

[0044] Further, the positioning block 26 is movable, and the position of the positioning block 26 can be adjusted according to the size of the paperboard; specifically, a through slot is arranged on the material placing plate 21, the length direction of the through slot is parallel to the axial direction of the rotating shaft 24, and the positioning block 26 cooperates with the through slot through a bolt, so that the position of the positioning block 26 can be adjusted along the through slot.

[0045] In the embodiment, the limiting plate 31 is provided with the accommodating groove 311 which is open towards the material placing plate 21 at one end away from the conveying belt 1, the buckle 312 is arranged in the accommodating groove 311, the buckle 312 is hinged to the limiting plate 31 at one end close to the conveying belt 1, the blocking part 313 is arranged on the buckle 312 at one end away from the conveying belt 1 and protrudes towards the material placing plate 21, and the blocking part 313 is used to contact the upper end of the paperboard away from the conveying belt 1;

[0046] The groove bottom of the accommodating groove 311 is provided with the mounting groove 314, the spring 315 is arranged in the mounting groove 314, and the spring 315 is located between the buckle 312 and the groove bottom of the mounting groove 314, so that the buckle 312 can be elastically swung.

[0047] When the paperboard is stacked on the blocking block 22, the buckle is pressed downwards under the action of the spring 315, the blocking part 313 contacts the upper end of the lowermost paperboard away from the conveying belt 1, and the blocking part 313 cooperates with the blocking block 22 to stably support the stacked paperboard; when the paperboard is sucked out, the buckle 312 is swung upwards by the paperboard, so that the paperboard can be separated from the blocking part 313, and then the buckle 312 is quickly reset under the action of the spring 315 to continue to block the paperboard.

[0048] Meanwhile, the guide groove 316 is arranged on the buckle 312 and extends along the length direction of the buckle 312, the limiting column 317 is arranged on the limiting plate 31 and passes through the guide groove 316, and the anti-disengagement head 318 is arranged on one end of the limiting column 317 away from the limiting plate 31, so that the outer diameter of the anti-disengagement head 318 is greater than the width of the guide groove 316, thereby preventing the limiting column 317 from being disengaged from the buckle 312, and the buckle 312 will not completely fall out when there is no paperboard.

[0049] In the embodiment, the limiting plates 31 are two and are arranged at intervals along the length direction of the mounting rod 32.

[0050] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
