Description

Bottle opening mold opening and closing driving mechanism of bottle making machine

Technical Field

The utility model belongs to the technical field of the bottle-making machine, relate to the bottleneck mould, specifically speaking are actuating mechanism that opens and shuts of bottle-making machine bottleneck mould.

Background

The bottle mouth of the bottle making machine is processed by extrusion molding through left and right half dies which slide in opposite directions. If the present applicant discloses a mouth-pressing forming control device for a bottle-making machine in chinese utility model patent document No. CN204550383, which was filed in 2015, 03, 10, the structure of the mouth-pressing forming control device comprises a driving motor, a swinging connecting plate, two track rods, two guide track seats and a sliding seat, wherein an output shaft of the driving motor is fixedly connected with a middle connecting hole of the swinging connecting plate, two swinging tracks are respectively arranged on two end faces of the swinging connecting plate, the two connecting seats are respectively assembled in the swinging tracks, the ends of the two track rods are respectively fixedly installed on the connecting seats, the two track rods are respectively installed in the guide track seats in a penetrating manner, the sliding seat is fixedly installed on the track rods, and mouth-pressing rollers are fixed on the sliding seat. When the mouth pressing forming control device of the bottle making machine is used, the driving motor directly drives the swinging connecting plate to do swinging motion through the output shaft of the speed reducer, and pushes the two track rods to generate opposite displacement to drive the pair of sliding seats on the track rods to generate relative motion, so that the two mouth pressing rollers do relative motion to implement the mouth pressing process. Although the structure can realize the opening and closing control of the bottle mouth mold to a certain extent, the structure has the following defects in the actual production and use:

one is that the structure is complicated, and occupation space is big. Because the mode that the motor directly drives the swinging connecting plate to rotate around the output shaft of the speed reducer through the output shaft of the speed reducer is adopted, the swinging central point of the swinging connecting plate is positioned at the outer side of the pressure joint line of the two pressure port rollers, and the two track rods are connected with the two pressure port rollers after extending for a certain length; and because the extension length of the track rod is longer, the guide track seat is required to be arranged to guide the movement of the track rod, so that the whole structure is more complex and the occupied space is large.

Secondly, the driving and positioning precision is low. Under the high-speed operation of the bottle making machine, the abrasion between the track rod and the guide track seat and between other machine parts is serious, so that the positioning precision of the pressure port roller is easily reduced, the product quality is influenced, and the unqualified product rate is increased. When the bottle is serious, the machine parts can be damaged or scrapped, and the normal operation of the bottle making machine is influenced.

Thirdly, the precision required for machining the machine parts is high, and the production and the manufacture are difficult.

And fourthly, the failure rate is high. The requirement on the degree of adaptability between each machine member is high in the working process, faults are easy to occur, the fault rate is high, the normal work of a workshop is influenced, and the working efficiency is reduced.
