A can clamping mechanism

Abstract

A tank clamping mechanism comprises a machine frame, two sets of clamping assemblies, a motor and a cam connected with the motor, wherein a lever is rotationally installed on the machine frame; an idler wheel is arranged at the lower end of the lever; the outer edge of the cam makes tight contact with the outer edge of the idler wheel; a connection rod is hinged to the upper end of the lever; two sets of movable blocks are hinged to the upper end of the connection rod and distributed on the left side and the right side of the connection rod correspondingly; lower shafts are installed at the ends, away from the connection rod, of the two sets of movable blocks; a swing arm is fixedly installed on each lower shaft; the swing arms are sleeved with upper shafts; the upper shafts are sleeved with the upper ends of the clamping assemblies; and the lower shafts are sleeved with the lower ends of the clamping assemblies. The cam and the connection rod mechanism are adopted for transmission, the tank clamping mechanism is simple and reasonable in structure, low in failure rate, convenient to adjust and maintain and low in energy consumption, has time sequence, and is stable and smooth in action in the movement process and small in clamp swinging angle, thereby being capable of conducting high-speed production and improving the work efficiency.

Description

technical field [0001] The invention relates to a clamp, in particular to a can clamping mechanism. Background technique [0002] The existing can clamping mechanism is generally composed of a pneumatic device, that is, a group of cylinders (or screw drive) controls the advancement of the can body, and another group of cylinders controls the opening and closing of the can clamping fixture. The problem with this can clamping mechanism is that when the pneumatic At the end of the action, the impact force of the entire can clamping fixture is relatively large, which is easy to squeeze the can body itself, resulting in deformation, and it is difficult for the entire can clamping mechanism to obtain a higher production speed during the movement process, which affects work efficiency. In addition, some current can clamping mechanisms use cams to directly act on the can clamping fixture fixing plate. Although high-speed production speed can be achieved and production efficiency can...

[0002] The existing can clamping mechanism is generally composed of a pneumatic device, that is, a group of cylinders (or screw drive) controls the advancement of the can body, and another group of cylinders controls the opening and closing of the can clamping fixture. The problem with this can clamping mechanism is that when the pneumatic At the end of the action, the impact force of the entire can clamping fixture is relatively large, which is easy to squeeze the tank itself, resulting in deformation, and it is difficult for the entire can clamping mechanism to obtain a high production speed during the movement process, which affects work efficiency

In addition, some can clamping mechanisms currently use cams to directly act on the clamping plate of the can clamping fixture. Although high-speed production speed can be achieved and production efficiency can be improved, the entire movement process is not smooth and smooth due to the large swing angle of the can clamping fixture.
