Description

Double servo motors and double punching arms

Technical Field

The utility model relates to the technical field of glass mechanical equipment feeders, in particular to double servo motors and double punching arms for punching.

Background Art

In the entire production process of glass bottles, feeders and bottle making machines are the main equipment on the glass bottle production line. In the feeder, the angle shear mechanism and the punching mechanism are the main components of the feeder. In the punching mechanism, the servo motor is generally used as a power to drive the punch mechanism to complete the punching. In the feeder, according to the number of droplets formed at the same time, it is divided into single drop, double drop, triple drop, etc.

The existing servo motor punching machine has only one servo punching motor. If it is a single drop feeder, it is no problem to achieve multi-material weight control. However, if it is a double drop feeder, it is very difficult to achieve multi-material weight control. Many companies have made improvements on the punch clamp to achieve multi-material weight control, but the effect is not ideal.

Based on the above technical problems, improvements in the punch clamp part did not achieve the ideal effect. Therefore, it can be achieved by using two servo motors, two sets of punching parts, and two sets of ball screws to independently control the corresponding punch operations. However, the direct contact process between the screw and the screw nut and the spring will cause spring wear. Long-term contact between the screw nut and the spring will affect the reliability of the screw nut.
