Abstract
A kind of bottle blowing machine core-pulling device pressure control mechanism, including the high-voltage tube equipped with high pressure valve and equipped with the low-voltage tube of low pressure valve, high-voltage tube connects the core-pulling device on bottle blowing machine by same compensation gas connector with low-voltage tube, separately there is the controller of control low pressure valve and high pressure valve work.Controller first controls low pressure gas and enters core-pulling device, and the core pulling handle of core-pulling device is made to be tightly attached to the surface of blowing mold core, then stops being passed through low pressure gas and being changed to be passed through high pressure gas, to form high pressure locking, realizes the atmospheric pressure compensating blown during bottle.The bottle blowing machine core-pulling device pressure control mechanism structure is simple; but it can effectively ensure that the atmospheric pressure compensating needs in bottle blowing machine; and make the pressure controllable for compensating gas; to greatly reduce the impact and damage probability that the components in bottle blowing machine and its interior core-pulling device generate; the safety of effective protection bottle blowing machine, and improve its service life.
Description
Technical field
The utility model relates to bottle blowing machine equipment, more particularly to one kind for controlling core-pulling device work in bottle blowing machine
The control mechanism of pressure.
Background technique
Bottle blowing machine after being heated, being blow molded to bottle embryo by, by bottle embryo blow molding, during blow molding, needing to mould
Tool is passed through high pressure gas to carry out pressure compensation, to guarantee the blowing quality of spue line among bottle.And it if desired blows and has
The bottle of handle also needs on bottle blowing machine that core-pulling device is arranged in handling position, forms handle by core-pulling device.Core pulling dress
It sets as shown in Figure 1, including core pulling handle 101, piston 102, and the spring 103 being set between core pulling handle and piston.In
When blowing bottle work, bottle blowing machine is passed through high pressure gas by direction shown in arrow in Fig. 1 with band piston movement, and then piston passes through again
Spring drives core pulling handle mobile, so that the handle blow molding of bottle.Although this kind of core-pulling device can blow with handles
Bottle, but because the pressure of high pressure gas is larger, it is larger with the mobile acceleration of piston, it is easy to make the components of core-pulling device
At frequent impact, spring is caused to be easy failure, or even damage core-pulling device or formation die core after a period of operation.
Summary of the invention
It is simple the purpose of the invention of the present invention is to provide a kind of structure and core-pulling device damage can be greatly reduced
The bottle blowing machine core-pulling device pressure control mechanism of probability, with protect core-pulling device and mold core using safe.
Bottle blowing machine core-pulling device pressure control mechanism described in the utility model, the high-voltage tube including being equipped with high pressure valve, and
One end of low-voltage tube equipped with low pressure valve, high-voltage tube and low-voltage tube each leads into high pressure gas and low-pressure gas, high-voltage tube and low
The other end of pressure pipe connects compensation gas connector, the core-pulling device on compensation gas connector connection bottle blowing machine simultaneously；Separately there is control low pressure
The controller of valve and high pressure valve work.
One end of bottle blowing machine core-pulling device pressure control mechanism described in the utility model, high-voltage tube and low-voltage tube connects respectively
It connects and the feeder of high pressure gas and low pressure gas is provided, and the other end passes through the core pulling dress of compensation gas fittings bottle blowing machine simultaneously
It sets, high pressure gas and low pressure gas is allowed to enter core-pulling device along high-voltage tube and low-voltage tube respectively, meanwhile, controller is connected and is controlled
High pressure valve on high-voltage tube and low-voltage tube processed and low pressure valve work, to control the open and close of high-voltage tube and low-voltage tube, thus control to
The air demand and gas supply air pressure of core-pulling device.When bottle blowing machine carries out blow molding work, controller controls low pressure valve opening first, makes
Low pressure gas enters core-pulling device through low-voltage tube and compensation gas connector, to drive the piston in core-pulling device and spring movement, makes
Core pulling handle is adjacent to the surface of blowing mold core；Then, high pressure valve opening is closed and controlled to controller control low pressure valve, makes high pressure gas
Enter core-pulling device through high-voltage tube and compensation gas connector, to form high pressure locking, realizes the atmospheric pressure compensating blown during bottle.It should
Bottle blowing machine core-pulling device pressure control mechanism structure is simple, but can effectively ensure that the atmospheric pressure compensating needs in bottle blowing machine, and
So that the pressure controllable of compensation gas, to greatly reduce the impact that the components in bottle blowing machine and its interior core-pulling device generate
And damage probability, the safety of effective protection bottle blowing machine, and improve its service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of core-pulling device in bottle blowing machine.
Fig. 2 is the structural schematic diagram of bottle blowing machine core-pulling device pressure control mechanism.
Fig. 3 is the use state diagram of bottle blowing machine core-pulling device pressure control mechanism.
Specific embodiment
As shown in Figure 2,3, a kind of bottle blowing machine core-pulling device pressure control mechanism, the high-voltage tube 1 including being equipped with high pressure valve 2,
With the low-voltage tube 3 that low pressure valve 4 is housed, one end of high-voltage tube and low-voltage tube each leads into high pressure gas and low-pressure gas, high-voltage tube
Compensation gas connector 5 is connected simultaneously with the other end of low-voltage tube, the core-pulling device on compensation gas connector connection bottle blowing machine；Separately there is control
The controller of low pressure valve and high pressure valve work.
As shown in figure 3, bottle blowing machine core-pulling device pressure control mechanism is installed on bottle blowing machine 100, and is connect by compensating gas
Core-pulling device on head connection bottle blowing machine, the low pressure gas that pressure is 0.7bar direction arrow P along figure is supplied to low-voltage tube, and is pressed
The strong high pressure gas for 30bar direction arrow Q along figure is supplied to high-voltage tube.When bottle blowing machine carries out blow molding work, controller is (not
Diagram) low pressure valve opening is controlled first, low pressure gas enters core-pulling device through low-voltage tube and compensation gas connector, so that core pulling be driven to fill
Piston and spring in setting is mobile, and core pulling handle is made to be adjacent to the surface of blowing mold core；Then, controller control low pressure valve is closed simultaneously
It controls high pressure valve to open, high pressure gas is made to enter core-pulling device through high-voltage tube and compensation gas connector, to form high pressure locking, realize
Blow the atmospheric pressure compensating during bottle.
The bottle blowing machine core-pulling device pressure control mechanism, on low-voltage tube 3, low pressure valve 4 and compensation gas connector 5 it
Between, the check valve 6 of compensation gas connector one end can only be flowed to from low pressure valve one end equipped with supplied gas.The setting of check valve is so that gas
Bottle blowing machine can only be flowed to from one end of low pressure valve, this can prevent the gas supply end of high pressure gas inflow low pressure gas, to guarantee air pressure
Accuracy, and then guarantee low pressure gas driving core-pulling device piston when can make core pulling handle be tightly attached to blowing mold core surface,
Without generating shock with blowing mold core.
