Servo driving device of paper brick-shaped germ-free filling machine

Abstract

The invention provides a servo driving device of a paper brick-shaped germ-free filling machine. The servo driving device is characterized by comprising an inner servo motor and an outer servo motor, wherein each servo motor is fixed at the bottom of a corresponding servo motor seat through a supporting column; the middle output shaft of each servo motor is connected with a ball screw on the corresponding servo motor seat through a coupling; a lower bearing pedestal of each ball screw is fixed on the corresponding servo motor seat; the lower side of a screw nut on each ball screw is connected with a corresponding main guide column fixing plate; and an upper bearing pedestal of each ball screw is fixed on the top of the corresponding servo motor. The cam driving of the conventional filling machine is changed to servo driving; and the servo driving device has the advantages that structure is simple, operation is convenient, reject rate is low, the speed adjustment is smooth, running is stable, and the like.

Description

technical field [0001] The invention belongs to the technical field of food and beverage filling machinery and equipment, and relates to a servo drive device for a paper brick-shaped aseptic filling machine, which is used as a power source for pre-forming actions such as pulling, sealing, forming, and cutting. Background technique [0002] At present, food filling machines are widely used by food companies. The pre-forming mechanism such as pulling, sealing, forming, and cutting is an important mechanism of the filling machine. Several actions are required to be very coherent and precise. Delays will prevent normal production, and there will be undesirable phenomena such as extrusion during forming, no forming, poor forming, bagging, leaking, rotten bags, and cutting. The action of the front forming mechanism is completed by the traditional structure, which is completed by four cams driving the four main pillars to move up and down according to their motion tracks. ...

AI Technical Summary

Problems solved by technology

Because the motion track of the cam will inevitably have errors in processing, installation, debugging, etc., and the wear of the cam, there will be some uncoordinated movements of the filling equipment during normal production and operation.

In addition, since the cam motion needs to be powered by a transmission mechanism such as a motor, a reducer, a shaft, a sprocket chain, and a coupling, it has a large structure, high cost, short service life, unstable mechanical motion, loud noise, and transmission errors. Defects such as large size, unstable movement point accuracy, and difficult speed improvement seriously affect the production efficiency, product quality and stability of modern filling machines, and cannot meet the high-efficiency and high-quality needs of enterprises.
