Description

Technical Field

[0001] The invention relates to the technical field of packaging carton gluing machines, in particular to a packaging carton gluing machine. Background Art

[0002] When producing packaging cartons, in addition to folding and gluing the cardboard into a frame, it is also necessary to glue and seal the transverse bottom plate and the longitudinal bottom plate at the bottom of the packaging carton, that is, glue is applied on the transverse bottom plate, and then the longitudinal bottom plate is pressed on the transverse bottom plate to bond the transverse bottom plate and the longitudinal bottom plate. The prior art uses hand-held packaging cartons and then uses a glue coating machine to apply glue on the longitudinal bottom plate. However, on the one hand, the hand-held packaging carton cannot ensure that the glue layer on the longitudinal bottom plate is at the center of the longitudinal bottom plate, resulting in that when the transverse bottom plates are folded in half, one of the transverse bottom plates cannot contact the glue layer, and one of the transverse bottom plates cannot be glued to the longitudinal bottom plate. On the other hand, the longitudinal bottom plate will warp up, resulting in uneven coating of the glue layer. In addition, the glue coating machine cannot control the timely opening and closing of the glue coating port before and after gluing, resulting in glue overflow, waste of glue, and easy environmental pollution, or dripping on the outer wall of the carton, resulting in unqualified carton production.

A gluing mechanism is arranged on the reciprocating mechanism, and one end of the gluing mechanism is in active contact with the L-shaped limiting plate 8. When the upper end of the gluing mechanism is against the bottom of the L-shaped limiting plate 8, the glue in the gluing mechanism cannot flow out. When the upper end of the gluing mechanism is in sliding contact with the end of the L-shaped limiting plate 8, the glue in the gluing mechanism flows out. The bottom of the gluing mechanism is a short distance away from the upper part of the longitudinal bottom plate 5 and does not contact the longitudinal bottom plate 5. The gluing mechanism is located at the upper center of the packaging carton 3, and the glue flowing out of the gluing mechanism is coated on the center of the longitudinal bottom plate 5.

[0023] The reciprocating mechanism includes bearings 9 and a motor 10 respectively arranged on the two side walls of the gantry 6. A threaded rod 11 is arranged on the motor 10, and the threaded rod 11 is connected to the bearing 9. The motor 10 drives the threaded rod 11 to rotate in the bearing 9.

When the glue coating tank 14 does not apply glue to the longitudinal bottom plate 5, the first spring 21 is in a compressed state. When the triangular pyramid 17 is in sliding contact with the L-shaped limit plate 8, the first spring 21 rebounds, driving the first circular plate 19 to rise, and the first circular plate 19 drives the lifting rod 20 and the sealing rod 22 to rise, and the sealing rod 22 is separated from the glue coating port 16, so that the glue coating port 16 is opened, and the glue flows out from the glue coating port 16.

[0027] The pressing member includes an L-shaped round rod 23 arranged on both sides of the conical tank 14, a second circular plate 24 is arranged inside the L-shaped round rod 23, a second spring 25 is arranged between the second circular plate 24 and the L-shaped round rod 23, a hollow section inside the L-shaped round rod 23, a telescopic rod 26 is arranged at the bottom of the second circular plate 24, the telescopic rod 26 passes through the inner side of the second spring 25 and penetrates the bottom of the L-shaped round rod 23, a pulley 27 is arranged on the telescopic rod 26, when the pulley 27 is not in contact with the longitudinal bottom plate 5, the second spring 25 is in a compressed state, when the pulley 27 is in contact with the longitudinal bottom plate 5, the pulley 27 is pushed up while rolling, the pulley 27 drives the telescopic rod 26 and the second circular plate 25 to rise, the second spring 25 is stretched, and at the same time, the pulley 27 presses the longitudinal bottom plate 5 on the square table 2 when rolling on the longitudinal bottom plate 5.

[0028] Working principle of the present invention:

[0029] Put the packaging carton 3 upside down on the square table 2, start the motor 10, the motor 10 drives the threaded rod 11 to rotate, so that the threaded sleeve 12 moves to the right on the threaded rod 11, and the slide plate 13 moves synchronously in the limiting groove 7. The threaded sleeve 12 drives the connecting rod 15, the conical tank 14, the L-shaped round rod 23, the telescopic rod 26 and the pulley 27 to move synchronously. When the triangular pyramid 27 slides and contacts with the end of the L-shaped limiting plate 8, the first spring 21 rebounds, driving the first circular plate 19, the triangular pyramid 17, the lifting rod 20 and the sealing rod 22 to rise, and the sealing rod 21 is separated from the glue coating port 16, and the glue flows out from the glue coating port 16. At this time, the glue coating port 16 is located at the left end of the longitudinal bottom plate 5, and the glue remains at the center of the longitudinal bottom plate 5. At the same time, the pulley 27 rolls onto the longitudinal bottom plate 5, and the pulley 27 is pushed up while rolling, and the pulley 27 brings The movable telescopic rod 26 and the second circular plate 25 rise, the second spring 25 is stretched, and the pulley 27 rolls on the longitudinal bottom plate 5 to press the longitudinal bottom plate 5 onto the square table 2. As the conical tank 14 moves to the right, a glue layer is left on the longitudinal bottom plate 5. When the triangular pyramid 17 slides and contacts the L-shaped limit plate 8 on the right, the triangular pyramid 17 is pressed down by the L-shaped limit plate 8, and the sealing rod 22 also gradually descends until the triangular pyramid 17 reaches the bottom of the right L-shaped limit plate 8. The glue application port 16 just reaches the right end of the longitudinal bottom plate 5, and the sealing rod 22 is inserted into the glue application port 16 to form a seal with the glue application port 16. The glue no longer flows out, and the gluing is completed. Then the conical tank 14 continues to move to the right for a distance, and the operator presses the transverse bottom plates 4 against the longitudinal bottom plate 5 to bond the longitudinal bottom plate 5 to the transverse bottom plate 4.

[0030] The present invention is simple to operate, convenient to use, and suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
