Carton feeding mechanism of packaging machine

Abstract

The invention relates to a carton feeding mechanism of a packaging machine. The carton feeding mechanism comprises a machine frame, an air cylinder assembly, a swing rod assembly, suckers assembly and a carton placing cavity assembly. The carton feeding mechanism is characterized in that the air cylinder assembly and the carton placing carton cavity assembly are fixed on the front end face and the upper end face of the machine frame through an air cylinder installing plate and a carton placing supporting frame respectively. An L-shaped swing rod of the swing rod assembly is hinged to the inside of the machine frame below the carton placing supporting frame through the swing rod support and the swing rod supporting shaft. One end of the L-shaped swing rod is connected with the air cylinder assembly movably, the other end is provided with the sucker assembly, and vacuum suckers of the sucker assembly correspond to a carton placing cavity of the carton placing cavity assembly. The carton feeding mechanism is driven by an air cylinder and is clean and hygienic, reliable in motion and simple in structure. The suckers are used for sucking a carton so that the surface of the carton can not be damaged. In addition, two suckers are used for adsorbing, and reliability of the adsorption is guaranteed. A baffle is adopted for restraining movement of the carton, unfolding of the carton is assisted, and reliability of unfolding and off-line of the carton is guaranteed.

Description

technical field

[0001] The invention relates to a packaging machine, in particular to a box feeding mechanism of the packaging machine. Background technique

[0002] Packaging machine is a high-tech automatic production equipment developed in recent decades. In the food and pharmaceutical industries with high efficiency and mass production, packaging machinery has special significance. The packaging machine is a kind of machine that automatically loads the loaded items into the carton and completes the action of closing the box. The initial state of the carton used in the packaging machine is generally folded, so the first action of the packaging machine is to unfold the carton and go down to the main line of cartoning. This mechanism is called the box feeding mechanism.

[0003] Chinese patent application number CN201210086234.3 discloses a box-feeding mechanism for a cartoning machine, including a box-suction member and a box-opening member. The box cam is used to contro...
