Double-position paper box suction forming mechanism

Abstract

The invention discloses a double-position paper box suction forming mechanism. The mechanism comprises a rotating disc and a ventilation fixed shaft, wherein a sun gear is fixedly mounted at the shaftend of the ventilation fixed shaft; the sun gear drives a planet gear through an intermediate idle gear; intermediate idle gear shafts and planet gear shafts are mounted on the rotating disc; the front shaft end of the planet gear shaft is connected with a gas distribution block; and a suction nozzle is mounted on the gas distribution block. The mechanism is characterized that only one set of planet gear shafts and gas distribution blocks is provided; a ventilation rod is connected with the front end of the gas distribution block; the suction nozzles are mounted at the upper and lower rod ends of the ventilation rod; the suction nozzle at the upper rod end and the suction nozzle at the lower rod end are symmetrical to the rotating center of the planet gear shaft; the ratio of number of teeth of the planet gear to the sun gear is 1: 1.5, so that motion trails of the suction nozzle at the upper rod end and the suction nozzle at the lower rod end are regular triangles with the same shapes during the process of 360-degree rotation of the rotating disc, the mechanism has the advantages that single gas distribution block design is adopted, the structure is simplified, the boundary dimension is small, the box suction speed is increased, the automatic opening forming of a paper box can be further realized during the process of paper box suction, and the paper box quality is guaranteed.

Description

technical field [0001] The invention relates to a cartoning machine, in particular to a carton suction forming mechanism of the cartoning machine. Background technique [0002] The boxes of the cartoning machine are generally stacked in the box warehouse, which need to be sucked up by the carton suction mechanism in turn, and then placed in the conveyor grid of the box feeding conveyor belt to be opened, and then conveyed by the conveyor grid of the box feeding conveyor belt. In order to increase the speed of the suction box, the carton suction mechanism of the prior art, such as the utility model patent of the patent number 201721435193.9 and the patent name "Multi-suction head planetary rotary lower box mechanism" applied by the applicant on November 1, 2017, rotates Three or four sets of gas distribution blocks are often installed on the disk to install the suction nozzle, which has a complicated structure. At the same time, because multiple planetary wheels and intermedi...

Problems solved by technology

In order to increase the speed of the suction box, the carton suction mechanism of the prior art, such as the utility model patent of the patent number 201721435193.9 and the patent name "Multi-suction head planetary rotary lower box mechanism" applied by the applicant on November 1, 2017, rotates Three or four sets of gas distribution blocks are often installed on the disk to install the suction nozzle, which has a complicated structure. At the same time, because multiple planetary wheels and intermediate wheels are to be installed, and the setting of the gas distribution pipeline must be considered, the size of the rotary disk It must also be larger, that is, the outer dimension of the carton suction mechanism is large; in addition, after the suction nozzle sucks the carton in the box compartment, it only pre-opens the carton by touching the block on the travel path, and the carton is fully opened. Forming should be completed in the conveyor grid of the box feeding conveyor belt. At this time, the carton is easily scratched by the collision of the conveyor grid, and the quality of the carton cannot be guaranteed.
