Description

Technical Field

[0001] The utility model relates to the technical field of packaging box opening tooling, in particular to a box sucking and opening mechanism for a cartoning machine. Background Art

[0002] A packaging box is a box used to package products. After the packaging boxes are generated in the packaging box production line, they are usually transported in a plate shape and transported to the packaging box opening tooling. The box opening structure makes the plate-shaped packaging box opened and packed, so that the subsequent tooling can seal the packaging box or fill it with materials. In the prior art, the box opening tooling adsorbs the plate-shaped packaging box through a suction head and cooperates with the suction head to open the packaging box through components such as a mechanical arm or a guide rod. However, the suction head of the box opening tooling in the prior art is usually a single suction head. The single suction head reciprocating box suction technology has very low adsorption efficiency and box opening efficiency, resulting in low box opening efficiency, which in turn affects the overall production efficiency of the packaging box production line. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a box suction and opening mechanism for a cartoning machine, which solves the problems in the prior art that the efficiency of sucking packaging boxes with a single suction head is too low and the box opening rate is low.

[0004] To achieve the above-mentioned purpose, the utility model provides a box sucking and opening mechanism for a cartoning machine, comprising a tooling seat and a base, a turntable and a plurality of suction head seats are movably arranged on the base, a main suction cup for contacting the outer wall of an external paper box is arranged on the plurality of suction head seats, the plurality of suction head seats are circumferentially distributed on the turntable and the spacing between adjacent suction head seats is equal, a driving member is arranged on the base for driving the plurality of suction head seats to perform orbital motion around the turntable as the center and driving the plurality of suction head seats to perform synchronous rotational motion, each of the suction head seats is provided with a main pipe for cooperating with an external vacuum pump to enable the main suction cup to generate an adsorption force, a matching seat is arranged on the tooling seat, a secondary suction cup is arranged on the matching seat for cooperating with any main suction cup when the main suction cup approaches the matching seat to realize a box opening operation on the paper box adsorbed on the suction cup, and a secondary pipe for cooperating with an external vacuum pump to enable the secondary suction cup to generate an adsorption force is arranged on the matching seat.

[0005] The advantages of adopting the above technical solution are as follows: the tooling seat is arranged on one side of the carton warehouse, so that when the carton warehouse transports the plate-like carton, the main suction cup on any suction head seat can adsorb the plate-like carton located at the outermost side of the discharge port of the carton warehouse; when the packaging box is opened, the driving member drives the plurality of suction head seats to perform orbital motion with the center point of the turntable as the reference point, so that the plurality of suction head seats can pass through the discharge port of the carton warehouse in turn and adsorb the plate-like carton located at the outermost side through the main suction cup. The suction head seat absorbs the plate-like paper box and then revolves along the turntable to the matching seat position. At this time, the main suction cup absorbs the inner wall of the plate-like paper box, and the auxiliary suction cup absorbs the outer wall of the plate-like paper box. Because the driving component drives several suction head seats to rotate synchronously, the suction head seat rotates and opens the plate-like paper box, so that the paper box is boxed. Because the driving component drives the suction head seat to revolve, the suction head seat moves to the box placement location with the opened paper box through the main suction cup and puts down the opened paper box. When the seat is driven to revolve and rotate, the paper box will break free from the auxiliary suction cup to ensure that the suction head seat moves with the opened paper box through the main suction cup; in the above technology, several main suction cups are set to improve the efficiency of adsorbing paper boxes, and at the same time, several main suction cups are used to drive the plate-shaped paper boxes to cooperate with the auxiliary suction cups in sequence to realize paper box opening, thereby improving the efficiency and stability of opening paper boxes. The setting of the above technology completes the automated opening operations of paper box suction, paper box opening and box placement, thereby improving the efficiency of opening paper boxes; in the above technology, the setting of the main pipe and the auxiliary pipe ensures that both the main suction cup and the auxiliary suction cup can generate adsorption force, thereby improving the stability of suction box; in the above technology, the base and the conveyor belt of the paper box warehouse are in a relatively vertical state, so that after the paper box is opened, the suction head seat will carry the opened paper box to the bottom of the base, and the vacuum pump is controlled to make the suction head seat no longer have adsorption force. At this time, the opened paper box will automatically fall onto the material conveyor belt due to the influence of gravity, that is, the automatic placement of the opened paper box is completed.

[0006] The utility model is further provided with: a driving cavity is hollowly provided in the base, the driving member includes a planetary gear set arranged in the driving cavity, the planetary gear set includes a main gear plate and a plurality of auxiliary gear plates, the main gear plate is coaxially arranged with the rotating disk, a driving shaft for passing through the bottom wall of the base and connecting with an external driving motor is connected at the center of the main gear plate, each end of the main pipe is inserted into the driving cavity, a plurality of auxiliary gear plates correspond to a plurality of main pipe ends one by one and are coaxially connected, each auxiliary gear plate is drivingly connected with the main gear plate with a matching gear plate, each matching gear plate is meshed with the main gear plate, each matching gear plate is meshed with the corresponding auxiliary gear plate, and the main gear plate and the rotating disk are detachably connected.

[0007] The advantages of adopting the above technical scheme are as follows: when it is necessary to drive the suction head holder to perform revolution and rotation, the operator starts the external drive motor, and the drive motor drives the main gear disc to perform axial rotation through the drive shaft, and the main gear disc is connected to the turntable, so that the turntable synchronously performs axial rotation, and the rotation of the turntable drives several suction head holders to perform revolution. When the main gear disc rotates, it will drive several mating gear discs engaged with it to rotate synchronously, and each mating gear disc is engaged with a secondary gear disc, so that the rotation of the main gear disc drives several secondary gear discs to rotate synchronously, that is, the rotation of the main gear disc drives several main pipes to rotate synchronously, and then drives the suction head holder to perform rotation through the main pipe; the above-mentioned technology is set to drive several suction head holders to perform revolution and rotation synchronously, and the whole transmission structure is compact and has high precision, which improves the stability of the self-rotation and revolution of the suction head holder to meet the working conditions of multiple suction heads for adsorption and box opening, thereby improving the number of boxes opened, the efficiency of box opening and the stability of box opening.

[0009] The advantages of adopting the above technical solution are as follows: in the above technology, the pneumatic slip ring is arranged to avoid the connection between the outlet pipe and the main pipe from being affected by components and getting stuck when the main pipe rotates and revolves, thereby ensuring the rotation stability of the main pipe; in the above technology, the pneumatic slip ring is also called a gas rotary joint, which is a rotary connection device for transmitting gas medium, which is a prior art, so its structure and function will not be described in detail; in the above technology, in order to ensure that the connection between the main pipe and the outlet pipe is more stable, a gas adapter with the same operating principle as the pneumatic slip ring can be rotatably connected to the bottom of the main pipe, and the gas adapter is connected to the outlet pipe to ensure that the gas adapter is in a relatively static state when the main pipe rotates, so as to avoid the connection between the gas adapter and the outlet pipe from being affected by components and getting stuck.
