When it is necessary to adjust the distance between the upper feeding assembly 100 and the lower feeding assembly 200 to adapt to cardboards of different thicknesses, the lift host 3 drives the lifting screw 2 to move up and down, thereby driving the upper feeding assembly 100 away from or close to the lower feeding assembly 200.

[0025] The upper feeding assembly and the lower feeding assembly each include two feeders arranged opposite to each other, and movable plates 29 are provided at both ends of the bottom of the feeders, and the movable plates 29 are installed on the optical axis 27 in a transverse sliding manner, and the two movable plates 29 arranged opposite to each other in a transverse manner are arranged on a driving screw assembly 28, and two independent driving screw assemblies are arranged on the upper feeding assembly to drive the two feeders to move relative to each other, and two independent driving screw assemblies are arranged on the lower feeding assembly to drive the feeders of the two lower feeding assemblies to move relative to each other. By driving the screw assembly to drive the two feeders to move toward or in the opposite direction on the optical axis, the spacing between the two feeders can be controlled, which is suitable for cardboards of different widths.

[0026] The feeders include a feeding and aligning unit 11, a folding unit 12, a deviation correcting unit 13 and a box stapling unit 14 in sequence according to the advancing direction of the cardboard.

[0027] The feeding and aligning unit includes a suction belt member 6 in the same direction as the cardboard conveying direction, a side plate 4 is horizontally arranged above the suction belt member 6, two side clapping plates 5 are slidably installed on the side plate 4, and the two side clapping plates 5 reciprocate relative to or towards each other under the action of the side clapping screw driving member 21, and the conveying end of the suction belt member 6 is provided with two rubber rollers 24 that rotate up and down relative to each other, and the conveying head end of the suction belt member 6 is provided with a rear gauge 7, and the upper end of the rear gauge 7 is on the same plane with the conveying surface of the suction belt member 6. The setting of the rear gauge 7 can increase the supporting length of the suction belt member 6, so as to facilitate the loading of cardboards of different lengths.

[0028] A neatly arranged stack of cardboards is placed on the upper end of the suction belt, and two side slappers are set at both ends. The suction belt drives the cardboards at the lower end to pass through the side plates and the suction belt, pass through two rubber rollers and enter the folding unit. The latter two side slappers move inward at the same time under the action of the side slap screw driving member to align the remaining cardboards to avoid offset and improve the accuracy of nailing boxes.

[0030] After the folding conveyor belt receives the cardboard transmitted from the feeding and aligning unit, it is gradually folded along the fold of the cardboard under the action of the guide member. When it reaches the curved beam, the folded part of the cardboard enters the curved groove of the curved beam, and the unfolded part of the cardboard is restricted by the restriction plate to prevent deviation. The setting of the curved beam prevents the folded part of the cardboard from shaking unstably, resulting in gaps when nailing the box, resulting in invalid nailing of the box. The two pieces of cardboard are folded upward or downward by the setting of the guide plate and the curved beam, so that the two sides of the two pieces of cardboard are connected, thereby facilitating the nailing of the box. The work efficiency is improved and no manual operation is required.

[0031] The deviation correction unit includes a plurality of clamping and conveying components 1, at least two of which are arranged on the horizontal part of the folded cardboard, and at least one of which is arranged on the vertical part of the folded cardboard.

The servo motor drives the sprocket to rotate, thereby driving the chain to rotate, and then the clamping plates arranged on the chain move forward, driving the clamped cardboard forward.

[0032] The cardboard is arranged in the clamping channel and clamped by two clamping plates. When the photoelectric detection switch detects that there is an offset between the upper and lower pieces of cardboard, the clamping and conveying parts of the upper feeding component or the lower feeding component move relative to each other to achieve the effect of deviation correction. After the deviation correction is completed, the cardboard is sent to the nail box unit.

[0033] The nailing box unit is arranged on the side of the transmission end of the deviation correction unit. The nailing box unit is arranged at the connection of two paperboards, so as to facilitate nailing the paperboards.

[0034] The utility model can realize autonomous feeding through the setting of the feeding and aligning unit, and can ensure the accuracy of the feeding position and direction of the cardboard. The folding unit can automatically fold the cardboard upward or downward, so that the two sides of the two pieces of cardboard are in an overlapping state. The deviation correction unit keeps the progress of the two pieces of cardboard consistent to avoid transmission errors, and then nail the box, which has high accuracy, reduces the waste rate, and improves work efficiency. At the same time, the spacing between the upper feeding component and the lower feeding component of the utility model is adjustable, and the distance between the two feeders is adjustable, which can be suitable for cardboards of different sizes, reducing equipment expenditure and saving costs. The setting of the I-beam increases stability and extends the service life of the nailing box unit.
