Description

Technical Field

[0001] The utility model relates to the technical field of box opening equipment, in particular to a device for unscrewing an inner cover of a packaging box. Background Art

[0002] In the production of standard cigarettes, paper packaging boxes are mostly used to pack the produced standard cigarettes. The standard cigarettes are packed in packaging boxes and sent to the distribution center. At the distribution center, the cartons need to be disassembled and taken out, and then different cigarettes are packaged and sent to different sales points. The standard cigarettes are taken out of the carton. The whole unpacking process generally includes the following steps: cutting the sealing strip, opening the outer cover of the long side, opening the inner cover of the short side, and pushing the standard cigarettes out; the traditional cigarette box inner cover opening device opens the inner cover of the cigarette box in a vacuum suction cup structure. The vacuum suction cup structure has the following problems: the suction cup swing center and the inner cover swing center are in the same straight line, otherwise it is easy to generate a lateral force perpendicular to the suction direction of the suction cup between the suction cup and the inner cover surface, so that the suction cup and the inner cover are separated. In addition, the traditional vacuum suction cup inner cover opening device does not take into account the recovery distance when the vacuum suction cup is adsorbed, which further causes the suction cup to separate from the inner cover. The above problems often lead to the failure of vacuum suction cup lid opening, reduce the opening efficiency and increase the labor maintenance cost. Therefore, it is urgent to improve the traditional suction cup type cigarette box inner cover opening device to solve the above problems. Summary of the invention

[0003] The purpose of the utility model is to provide a device for unscrewing the inner cover of a packaging box in view of the above-mentioned problems, so as to solve the technical problems that the suction cup rotation center and the inner cover rotation center of the traditional packaging box inner cover unscrewing device are not easy to adjust to the same straight line, and the recovery distance during adsorption of the vacuum suction cup is not considered, resulting in the separation of the suction cup and the inner cover and the failure to open the cover.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0005] A device for unscrewing the inner cover of a packaging box, comprising a gantry, a horizontal moving part, a lifting part, a pair of unscrewing parts and a blocking and positioning structure; the gantry is mounted on a packaging box placement part, and a mounting plate is arranged on the gantry; the horizontal moving part is movably mounted on the mounting plate along the opening direction of the packaging box, the lifting part is liftably mounted on the horizontal moving part, the pairs of unscrewing parts are mounted on both sides of the lifting part, the horizontal moving part can drive the unscrewing parts to move horizontally, and the lifting part can drive the unscrewing parts to move up and down; the unscrewing part comprises an unscrewing connecting plate, an unscrewing drive, an unscrewing connecting piece and a suction cup; the unscrewing drive is connected to the lifting part through the unscrewing connecting plate, the unscrewing drive is provided with a downward output shaft, one end of the unscrewing connecting piece is connected to the output shaft, and the other end is connected to the suction cup; the blocking and positioning structure is mounted on one side of the gantry, and one side of the packaging box can be against the blocking and positioning structure.

[0007] Furthermore, the lifting part is provided with a longitudinal moving structure, and the longitudinal moving structure can drive the swing-opening part to move horizontally along a direction perpendicular to the opening of the packaging box.

[0008] Furthermore, the longitudinal movement structure includes a longitudinal telescopic cylinder and a longitudinal slide rail, and a swing-open connecting plate is slidably installed on the lifting part through the longitudinal slide rail. The telescopic end of the longitudinal telescopic cylinder is connected to the slidable connecting plate and drives the connecting plate to move.

[0009] Furthermore, the lifting part includes a second guide rod sliding sleeve structure, a lifting and telescopic cylinder and a lifting plate. The lifting plate can be movably installed on the mounting plate in a vertical direction through the second guide rod sliding sleeve structure. The lifting and telescopic cylinder is installed on the lifting plate. The protruding end of the lifting and telescopic cylinder can be against the mounting plate and push the lifting plate to rise.

[0010] Furthermore, the unscrewable connector is bent so that the unscrewable connector can avoid the packaging box.

[0012] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. When the utility model is used, the packaging box with the outer cover opened can be limited to move into position through the blocking positioning structure, and then the lifting part moves down to make the suction cup reach a height that can adsorb the inner cover; the unscrewing part is moved by the horizontal moving part, so that the suction cup slowly approaches the inner cover and adsorbs it steadily, and while the suction cup adsorbs, the suction cup's swing center coincides with the same position of the inner cover's swing center, and then the inner cover can be stably opened by the unscrewing part; based on the above, the utility model solves the technical problems that the suction cup's swing center and the inner cover's swing center of the traditional packaging box inner cover unscrewing device are not convenient to adjust to the same straight line, and the recovery distance of the vacuum suction cup during adsorption is not considered, resulting in the separation of the suction cup and the inner cover and the failure to open the cover.

[0014] 2. The utility model is provided with a longitudinal moving structure, which can adjust the distance between the two rotating output shafts, thereby achieving the effect of satisfying the use of packaging boxes of different widths and improving the scope of application.

[0015] 3. The utility model can improve the movement stability of the positioning baffle by providing a first guide rod sliding sleeve structure, and can improve the stability of the lifting part by providing a second guide rod sliding sleeve structure. BRIEF DESCRIPTION OF THE DRAWINGS
