Pushing mechanism for packaging production line

Abstract

The invention discloses a pushing mechanism for a packaging production line; the pushing mechanism comprises a stand (1) and a cylinder (2), wherein a cross beam on the top of the stand (1) is provided with a fixing seat (3) used for fixing the cylinder (2); the top of a piston rod (4) at the front side of the cylinder (2) is fixedly connected with a pushing platform (5); a push rod (6) fixedly connected with the pushing platform (5) is arranged at the lower side of the pushing platform (5); two guide seats (7) are respectively arranged at the two ends of the pushing platform (5) and are respectively provided with guide wheels (8); and the guide wheels (8) are movably connected with guide grooves (9) arranged on a longitudinal beam on the top of the stand (1). According to the pushing mechanism, the guide wheels which are matched with the guide grooves are respectively arranged at the two ends of the pushing platform, so that the off-tracking phenomenon of the push rod is eliminated, and the processing difficulty of the pushing mechanism can be reduced; furthermore, a straight rack is meshed with a gear, so that the movement accuracy of the push rod is further guaranteed; and the pushing mechanism has the characteristics of being simple in structure and convenient to operate, thus being suitable for the large-scale industrial packaging production line.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to a pushing mechanism for a packaging production line that does not deviate and is positioned accurately. Background technique [0002] The pushing mechanism of the existing packaging production line, in order to keep the push rod from wandering during the process of pushing the packing box, it is necessary to fix the top end of the piston rod to the middle of the side wall of the pushing platform with the push rod very accurately, so as to ensure that the push rod Driven by the push platform, it runs smoothly and straightly. This structure not only increases the processing difficulty of the push mechanism, but also causes the push platform to fail to run along a fixed straight line due to the slight swing of the piston rod, which in turn causes the push rod to deviate. Contents of the invention [0003] The object of the present invention is to solve the problems ex...
