Servo hydraulic type bottle cap compression molding machine

Abstract

A servo hydraulic type bottle cap compression molding machine comprises a main machine assembly, an extrusion mechanism, a feeding mechanism, a cap discharging mechanism, a die part and a transmission mechanism, all of which are arranged on a rack. The transmission mechanism is driven by a motor. The main machine assembly comprises a heavy load bearing arranged in the rack. The lower portion of the heavy load bearing is connected with a main shaft. The main shaft is connected with the transmission mechanism and provided with a precise electric conduction slip ring. One end of the precise electric conduction slip ring is connected with a rotary encoder connected with a human-computer interface. The human-computer interface is connected with an electric control valve connected with a die stripping and air blowing valve. A proportional servo hydraulic valve is arranged below a gland oil cylinder and provided with a pressure sensor. The pressure sensor is connected with a displacement induction piece connected with a displacement sensor. The displacement sensor is connected with the other end of the precise electric conduction slip ring. According to the scheme, the electric conduction slip ring is adopted for electric conduction, air blowing and die stripping are controlled through a servo hydraulic gland and the electric control valve, control is accurate, and the speed and the production efficiency are high.

Description

technical field [0001] The invention relates to a servo hydraulic bottle cap compression molding machine, which is mainly used for producing bottle caps of mineral water bottles, beverage bottles and oil bottles, etc., and belongs to the field of plastic machinery. Background technique [0002] At present, bottle caps such as mineral water bottles, beverage bottles and oil bottles are mainly molded by bottle cap molding machines. Install the upper mold and cover removal mechanism on the upper part, install the middle plate on the middle part of the integral rotating seat, install the lower mold on the middle plate, install the lower plate on the lower part of the integral rotating seat, install the oil cylinder ejection molding mechanism on the lower plate, and install the oil separator under the lower plate The main plate and the main shaft run through the upper plate, the integral rotating seat, the middle plate, the lower plate and the oil separator, and are connected to ...

AI Technical Summary

Problems solved by technology

The disadvantage is that it is troublesome to install, the coaxiality between the boards needs to be adjusted, and it is not easy to debug, especially the main shaft needs to be very thick so as not to break, the cost is high and heavy, the bearings of each board need to be replaced normally, and maintenance is inconvenient

In particular, when the upper gland of the lower mold of the existing molding machine and the blowing and demoulding of the upper mold, the rolling contact of the cam is used, which causes very large noise, and the reaction time of the rolling contact of the cam is delayed, resulting in a slow gland speed and low production efficiency. low efficiency
