Detailed Description

As shown in fig. 1 and 2, a carton stapler comprises a stapler frame 1, a feeding table 2, an electric telescopic air bar 3, a photoelectric sensor 4 and a PLC controller 9; the feeding table 2 is located on one side of a feeding hole of the frame 1 of the stitching machine, and the feeding table 2 is used for stacking corrugated paper to be fed. The guide hole 5 that has two vertical rectangular shapes is opened symmetrically in the

stitching machine frame

1, 2 bottoms of material loading platform are fixed with two triangular supports 6 that match with guide hole 5, triangular support 6 inserts and stretches into the stitching machine frame 1 behind the guide hole 5 in, electronic flexible air bar 3 is connected to the below of triangular support 6, electronic flexible air bar 3 can drive material loading platform 2 and triangular support 6 and rise or descend together to change the height of material loading platform 2. Two parallel feeding baffle plates 7 are installed in the frame 1 of the nailing machine, and the two feeding baffle plates 7 can limit corrugated paper to move forwards along the feeding direction, so that a feeding path is guided. The stitching machine head 8 is positioned between the two feeding baffle plates 7, and the stitching machine head 8 can shoot the nails towards the corrugated paper, so that the corrugated paper is stitched. The photoelectric sensor 4 is embedded on the feeding baffle on the left side, a detection head of the photoelectric sensor 4 faces the feeding baffle on the right side, the photoelectric sensor 4 and a feeding plane of the corrugated paper are on the same plane, and the photoelectric sensor 4 can detect the feeding state of the corrugated paper; the photoelectric sensor is installed in an embedded mode, so that the photoelectric sensor cannot be touched and rubbed by corrugated paper in feeding. Install the control box of taking PLC controller 9 on the stitching machine frame 1, PLC controller 9 is connected to photoelectric sensor 4 electricity, electronic flexible air bar 3 is connected to PLC controller 9 electricity, when photoelectric sensor 4 detects the corrugated paper feeding, give PLC controller 9 with detected signal transmission, PLC controller 9 then controls electronic telescopic cylinder 3 and upwards stretches out the distance that one end was set for, this distance equals the thickness of corrugated paper, thereby make the corrugated paper of the superiors on material loading platform 2 keep the same height with the feeding plane all the time, do not need to remove the corrugated paper earlier when the workman feeds in advance and then pay-off forward, it is light laborsaving, the material loading is quick, man-hour has been saved, the workman also need not judge the opportunity of promoting the material loading platform and the height of manual control material loading platform, the degree of automation of equipment has been improved.

Triangular supports 6 still includes the interior spacing portion 10 that upwards extends, the width of interior spacing portion 10 is greater than the width of guiding hole 5, interior spacing portion 10 butt is on the inside wall of stitching machine frame 1, when the outside that makes material loading platform 2 keep away from stitching machine frame 1 has the trend of downward sloping because the corrugated paper on material loading platform 2 is heavier, interior spacing portion 10 supports stitching machine frame 1 from the inboard of stitching machine frame 1, thereby restrict the outside downward sloping of material loading platform 2, guarantee material loading platform 2 and be in the horizontality all the time, prevent that the corrugated paper from sliding down from material loading platform 2.

Fixedly connected with crossbeam 11 between two triangular supports 6, electronic flexible air bar 3 is located crossbeam 11 central authorities, is fixed connection between the piston rod of electronic flexible air bar 3 and crossbeam 11. The electric telescopic cylinder 3 simultaneously supports the two triangular supports 6 through the cross beam 11, so that the left side and the right side of the feeding table 2 are synchronously lifted, and the phenomenon of deflection caused by asynchronism is avoided.

An auxiliary support 12 is welded between the bottom surface of the feeding table 2 and an inclined support of the triangular support 6, the auxiliary support 12 is located on the outer side of the frame 1 of the stitching machine, and the support strength of the triangular support 6 to the feeding table 2 is further enhanced by the auxiliary support 12.

As shown in fig. 2 and 3, a plurality of feeding rollers 13 are installed in the feeding plane of the feeding table 2, the feeding rollers 13 are arranged along a direction parallel to the beam 11, corrugated paper is placed on the feeding table 2, and then the corrugated paper is pushed forward, at this time, the feeding rollers 13 roll, so that the feeding process of the corrugated paper is easier.

The working process of the device is as follows: in the initial state, the feeding table 2 is lowered to the lowest point through the electric telescopic cylinder 3, and then the rising height of the electric telescopic cylinder 3 is input into the PLC 9 according to the thickness of the corrugated paper to be processed. Pile up a plurality of corrugated paper on material loading platform 2, make the corrugated paper height of the superiors and the feeding plane of stapler on the coplanar, then start the stapler, the workman begins to the feeding between two feeding baffle 7, promptly: folding the corrugated paper earlier, then insert the corrugated paper between last guide roller 14 and the lower guide roller 15 of stitching machine, then the stitching machine aircraft nose 8 stitching corrugated paper, in this process, whenever the corrugated paper feeding is detected to photoelectric sensor 4, just send a feeding signal to PLC controller 9 immediately, PLC controller 9 then control electric lift cylinder 3's piston rod once according to the distance of setting for, make the corrugated paper of the superiors keep the same height in the feeding plane at all, the direct propelling movement corrugated paper that gos forward during the workman's feeding can.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
