The working principle of the invention is as follows: when the machine is started, the roller motor 7 drives the roller shaft 8 to rotate, and then drives the concave-convex buckle roller 2 to rotate so as to release the concave-convex buckle self-sealing strip 6, the front guide wheel 4 and the counterweight sensing wheel 5 arranged on the buffer sliding chute 3 form a stretching state through winding of the concave-convex buckle self-sealing strip (6), when the counterweight sensing wheel 5 is pulled to the vicinity of the upper limit sensor 9-1 by the concave-convex buckle self-sealing strip 6, the upper limit sensor 9-1 generates a signal to inform a control system that the concave-convex buckle self-sealing strip 6 is insufficient in buffer, the roller motor 7 is controlled to rotate, more concave-convex buckle self-sealing strips 6 are released, at the moment, the counterweight sensing wheel 5 can descend along with the increase of the concave-convex buckle self-sealing strip 6, and when the counterweight sensing wheel 5 is pulled to the vicinity of the lower limit sensor 9-2 by the concave-convex buckle self-sealing strip 6, the lower limit sensor 9-2 generates a signal to inform a control system that the concave buckle self-sealing strip 6 is sufficiently buffered, and at the moment, the roller motor 7 stops rotating, so that the purpose of design is to ensure that the concave-convex buckle self-sealing strip 6 is stably released by connecting lines, various cutting-off lengths are set or the machine is not more than compatible. After the self-sealing strip 6 is guided by the upper rear guide wheel 11 and the lower rear guide wheel 49, the self-sealing strip 6 enters a conveying cavity space through the front guide pipe 12, the self-sealing strip 6 is exposed between the front guide pipe 12 and the rear guide pipe 48 and is clamped by the upper conveying wheel 13 and the lower conveying wheel 14, the upper conveying wheel 13 and the lower conveying wheel 14 are mutually meshed in a gear structure, the self-sealing strip 6 is clamped, the self-sealing strip 6 is driven by the buckle conveying servo motor 15 to rotate, so that a pulling force is generated on the self-sealing strip 6, the self-sealing strip 6 is conveyed to a locating groove of the negative pressure roller 20 according to a fixed length of a parameter set by a program, and when the self-sealing strip 6 is conveyed by the buckle conveying servo motor 15 in a rotating mode, the buckle supporting cylinder 27 drives the buckle supporting bracket 28 and the buckle supporting wheels 29 to move downwards to press the buckle supporting wheels 29 on the upper surface of the self-sealing strip 6, and the purpose is to enable the self-sealing strip 6 to be fully contacted with the locating groove of the negative pressure roller 20. When the fixed-length conveying is finished after the button feeding servo motor 15 stops, the button pressing cylinder 25 drives the pressing block 26 to move downwards, and after the concave-convex button self-sealing strip 6 is pressed, the cutting cylinder 23 drives the cutter 24 to move downwards to realize fixed-length cutting of the concave-convex button self-sealing strip 6. In order to achieve the purpose of high-speed operation, the negative pressure roller 20 is provided with a plurality of positioning grooves, when the positioning grooves need to rotate to a heat sealing station after cutting, negative pressure generated by the negative pressure fan 36 enters the air slip ring 21 through the rear air pipe 22, the purpose of setting the air slip ring 21 is to solve the problem that a rotating structure is not leaked, the number of air paths in the air slip ring 21 corresponds to the plurality of positioning grooves of the negative pressure roller 20 one by one, a plurality of through holes are formed in the positioning grooves of the negative pressure roller 20, and negative pressure finally generates suction force to the concave-convex buckle self-sealing strip 6 in the positioning grooves through the through holes, so that the purpose of adsorption is achieved, and the concave-convex buckle self-sealing strip 6 can not fall off when the negative pressure roller 20 rotates. When the rotary servo motor 34 drives the negative pressure roller 20 to rotate to the heat sealing station, the rotation is stopped, the heat sealing air cylinder 42 drives the heat sealing block 46 to move upwards, the bag film 47 is contacted with the concave-convex buckle self-sealing strip 6 in the positioning groove of the negative pressure roller 20, and the concave-convex buckle self-sealing strip 6 is heat-sealed at the appointed position of the bag film 47 through heat conduction. Because the packaging machine needs to package bags with different width sizes, the heat sealing position of the concave-convex buckle self-sealing strip 6 on the bag film 47 also needs to be adjusted according to the needs, when the adjusting hand wheel 40 is rotated, the adjusting screw rod 37 is driven to rotate so as to drive the whole negative pressure roller device to shift, thereby achieving the purpose of adjusting the position, and the adjusting position can be displayed on the installed position display 39 in real time.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
