Description
Technical field
The utility model relates to pharmaceutical machine apparatus field, specially a kind of bottle blowing machine exhaust apparatus.
Background technique
Bottle blowing machine is a kind of bottle making equipment of plastic infusion bottle production, is a kind of electrical-mechanical integration apparatus.Bottle blowing machine master
It is divided into three great institutions -- Shang Pei mechanism, heating mechanism, clamping.Plastic bottle forms mainly in clamping section.Clamping
By heated bottle base blow out plastic bottle need it is stretched, one blow, two blow and are vented and complete.As shown in Figure 1, its exhaust event is by arranging
Air valve 5 controls, and exhaust valve 5 is controlled by electromagnetic relay 2.Compressed air is by gas source 3 through check valve 4, exhaust valve 5 to exhaust nozzle
6 exhausts, to bottle base bleeding.The working principle of electromagnetic relay 2 is all by secured core, moves as A.C. contactor
Iron core, spring, movable contact, stationary contact 2-3, coil, connecting terminal and shell composition.Coil 2-1 is powered, and dynamic iron core is in electromagnetic force
Make lower dynamic actuation, drives movable contact 2-2 movement, separate normally-closed contact, normally opened contact closure；Coil 2-1 power-off, dynamic iron core exist
Movable contact is driven to reset under the work of spring.2 failure of electromagnetic relay accounts for relatively high in equipment fault.
Utility model content
Inventor observes the course of work of bottle blowing machine.Bottle blowing machine completion one blows the rear mold that two blow and starts to be vented,
Exhaust event delivers a signal to intermediate relay by PLC module, controls 15 exhaust valves 5 by intermediate relay.Existing equipment is adopted
Use electromagnetic relay as intermediate relay.The coil of electromagnetic relay is powered, and coil closes movable contact with stationary contact after being powered
It closes, connecting terminal is powered after contact closure, and electrical current is transmitted to exhaust check valve coil, and exhaust check valve coil is powered unidirectional
Valve events start to be vented, and exhaust is completed the molding of one mould bottle of bottle blowing machine and completed, and then carry out next mould bottle molding cycle circulation.
Although the capacity of electromagnetic relay is enough, since 15 exhaust valves are used in parallel, cause electromagnetic relay to load electrical
Characteristic is different from the electrical characteristic for the coil that one is equivalent to 15 exhaust valve control coils；Electromagnetic relay spoilage is higher.
After being changed to solid-state relay, seldom break down again.
As soon as above-mentioned bottle blowing machine, which often blows mould bottle exhaust check valve, need to arrange primary gas, electromagnetic relay contact closure is primary.It blows
20,000 bottles per hour of continuous production of machine of bottle, exhaust check valve is vented 1330 times per hour, and the contact of electromagnetic relay also will be per small
When act 1330 times, because electromagnetic relay stationary contact and movable contact can generate spark, generated fire in the moment that closure is powered
Flower number of dimensions is excessively easy to burn out relay coil to damage relay.
It is unique that the purpose of the utility model is to provide a kind of structure novels, easy to use, and can reduce bottle blowing machine event
The bottle blowing machine exhaust apparatus of barrier rate；The specific technical proposal is:
A kind of bottle blowing machine exhaust apparatus, including gas source, exhaust nozzle, exhaust valve and control unit；The exhaust nozzle with it is described
By piping connection between gas source, described control unit controls exhaust valve by intermediate relay, realizes exhaust nozzle exhaust or stops
Only it is vented；The intermediate relay is solid-state relay.
Further, the exhaust valve is exhaust check valve.
The utility model bottle blowing machine exhaust apparatus passes through the intermediate relay that will control exhaust check valve by electromagnetic relay
It is changed to solid-state relay；Reduce bottle blowing machine failure rate.
Detailed description of the invention
Fig. 1 is bottle blowing machine exhauster structure schematic diagram in the prior art；
Fig. 2 is the utility model bottle blowing machine exhauster structure schematic diagram.
In figure: 1, control unit；2, electromagnetic relay；2-1, coil；2-2, movable contact；2-3, stationary contact；3, gas source；
4, check valve；5, exhaust valve；6, exhaust nozzle；7, exhaust check valve；8, solid-state relay.
Specific embodiment
The utility model is made a more thorough explanation below with embodiment.The utility model can be presented as it is a variety of not
Same form, should not be construed as limited to the exemplary embodiments described herein.
The spatially relative terms such as "upper", "lower" " left side " " right side " can be used herein for ease of explanation, for saying
Relationship of the elements or features relative to another elements or features shown in bright figure.It should be understood that in addition in figure
Except the orientation shown, spatial terminology is intended to include the different direction of device in use or operation.For example, if in figure
Device is squeezed, and is stated as being located at other elements or the element of feature "lower" will be located into other elements or feature "upper".Cause
This, exemplary term "lower" may include both upper and lower orientation.Device, which can be positioned in other ways, (to be rotated by 90 ° or is located at
Other orientation), it can be interpreted accordingly used herein of the opposite explanation in space.
As shown in Fig. 2, the bottle blowing machine exhaust apparatus in the present embodiment, including gas source 3, exhaust nozzle 6, exhaust valve and control are single
Member 1；By piping connection between exhaust nozzle 6 and gas source 3, control unit 1 controls exhaust valve by intermediate relay, the row of realization
Gas nozzle 6 is connected to or is disconnected with gas source 3 to realize exhaust or stop exhaust.Intermediate relay in the present embodiment is solid-state relay
8.Solid state relay is a kind of all electronic circuit composition element, it by semiconductor devices and electronic component electricity, magnetically and optically
Characteristic completes its partition and relay handoff functionality, it is mainly characterized by no contact with intermediate relay compared with, without mechanical
The relay of component movement, relay function are suitable for the control of exhaust check valve as intermediate relay and do not generate electricity
Arc is hardly damaged.Control unit 1 can be PLC, industrial personal computer or single-chip computer control system.
There are multiple exhaust nozzles 6 in equipment to one group of bottle base while being exhausted.Since multiple exhaust nozzles need to share gas source 3,
In order to avoid other exhaust nozzles of exhaust valve gas leakage effect work normally in exhaust valve in parallel；It needs gentle in exhaust valve
Check valve is concatenated between source.In order to keep the structure of equipment simpler, the exhaust valve in embodiment will be unidirectional using exhaust check valve 7
Valve and gas exhausting valve integrate, without individually concatenating check valve in pipeline.
Above-mentioned example is only intended to illustrate the utility model, and in addition to this, also there are many different embodiments, and these
Embodiment be all those skilled in the art after comprehension the utility model thought it is also envisioned that therefore, no longer arrange one by one herein
It lifts.
