Description

Automatically controlled tear drop wafering type blowing machine

The utility model relates to a kind of automatically controlled tear drop wafering type blowing machine that is used to make all size glass cell-shell.

General commonly used tear drop wafering type blowing machine mainly adopts the machine driven system of being made up of powder coupling mechanism, belt dressing, polydisc variator, two pairs of conical gear etc. of driven by motor, drives that the host work platform rotates and connect pressurized air by timing cam controls feeding machine work.Host work platform velocity of rotation utilizes handwheel to regulate the polydisc variator, the output shaft of manual shift variator drives chain wheel set through a pair of conical gear and drives worktable conversion rotating speed, meanwhile another drives the rotation of differential mechanism driving timing cam to conical gear, and make timing cam connect compressed-air actuated timing valve, with the rotation phase that differential mechanism is regulated material cake feed device, use the work at each position of air-operated drive feeding machine.Because of needing artificial adjustment handwheel, timing cam makes devices such as the gob lifting of its driving, suction nozzle revolution, keep synchronously with the blow head device on the host work platform, so be difficult to accurately to coordinate the synchronization action between each bilge construction, in addition because the progressive error of generations such as mechanical transmission, mechanical wear, artificial adjustment, normal operation to equipment, quality, quantity to the cell-shell product all have influence in various degree, and these are the existing insurmountable hard nut to cracks of tear drop wafering type blowing machine always.

The purpose of this utility model provides a kind of automatically controlled tear drop wafering type blowing machine, it simplifies mechanical transmission structure, adopts advanced electronic control technology to control each action of this machine, significantly improves working efficiency and quality product, saving of labor, material-saving reduce maintenance cost and manufacturing cost.

The purpose of this utility model is achieved in that the machine driven system that this device comprises that the wheel casing of driven by motor is formed and the host work platform and the feeding machine of driving thereof, wherein variable-frequence governor and corresponding electrical element and the power switch of motor by having nixie display joins, the wheel casing horizontal output shaft joins by tachogenerator and programmable logic controller, the programmable logic controller output terminal connects the air-operated solenoid valve of rly. control, and drives the pneumatic actuator that each parts of control feeding machine are finished corresponding actions respectively.

Because having cancelled the traditional handwheel of tear drop wafering type blowing machine, the utility model regulates the polydisc variator, and with variable-frequence governor control motor, the car soft start is opened in realization and host work platform rotating speed is adjusted in frequency conversion, both alleviated labor intensity of operating staff, guarantee the normal operation of equipment again, improved speed efficiency and accuracy.The timing cam that has handle that adopts advanced electronic control technology to replace differential mechanism to drive drives the corresponding actions that topworks's (cylinder) finishes each parts of feeding machine with the Controlled by Programmable Controller air-operated solenoid valve.It has effectively overcome the error that mechanical transmission, mechanical wears such as existing differential mechanism, timing cam cause, eliminated artificial adjustment error, can coordinate the devices such as gob pointer, suction nozzle revolution of feeding machine exactly, keep synchronously with blow head device on the host work platform.Thereby significantly improve quality product, its qualification rate is brought up to 95% from 90%, saving of labor, material-saving have been accomplished, output improves about 15%, because mechanical fault obviously reduces, so the corresponding minimizing of maintenance cost and maintenance man-hours has also reduced manufacturing cost, thereby solved the hard nut to crack that prior art exists.

The utility model is described in further detail below in conjunction with accompanying drawing.
