Description
Technical field
A kind of the invention belongs to shaping platform field, more particularly to shaping platform of vacuum fast shaping.
Background technology
Extrusion moulding production PVC door and window products are referred to：PVC material melts are plastified by extruder, then fused materials
The door and window section blank section bar of required specification is shaped in slit die, is sent after shaping platform cooling and shaping, traction cutting
Pack to tilting trestle windrow.In the PVC production lines, the Main Function of shaping platform is that the section bar that shapes for needs provides cooling water
And negative-pressure vacuum.
Generally 5 meters ~ 8 meters of the length of domestic routine shaping platform, typically all adopts liquid-ring type vacuum in Vacuum shaping
Pump is carried out vacuumizing setting up negative pressure to section of shaping, and so as to accelerate the flowing of water in sizing section, and then quick cooling section bar carries out determining
Type, vacuum requirement highest when its medium section has just enter into sizing section to section of shaping, sets up negative pressure for prestissimo and often exists
Sizing section is vacuumized foremost namely with the water-ring vacuum pump 1 of money using multiple stage where section bar is entered at first, such as Fig. 1
Shown, but water ring vacuum pump is usual by the way of directly supplying water during actual industrial onsite application, by a standing valve
Gate control water-supply quantity, and then determine that control flows into the water level height in the pump housing, this working method of water ring vacuum pump can not
The size of water ring is made in the optimal working condition of vavuum pump, when the rotating speed of motor certain, in certain water level range, water level
The water ring formed by height is big, and water level is low, and the water ring for being formed is little, i.e., when water ring is bigger than normal, increase can power consumption, therefore Water-ring vacuum
The efficiency of pump declines, and electric energy loss is increased；Meanwhile, and can be changed with the change of working condition due to water supply line output,
This vacuum for allowing for water ring vacuum pump is affected by certain, and this is high for freshly extruded section bar requires that vacuum is set up
And be influential soon, it is unfavorable for the initial good shaping of section bar, while increased energy loss again.Therefore shaping platform is in sizing section
All being vacuumized using water-ring vacuum pump easily increases energy loss, and vacuum effectiveness is not best.
Content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of shaping platform of vacuum fast shaping, it can be with
The negative pressure that most fast speed is set up needed for section bar, reduces start percent defective, and can reduce the energy consumption of vavuum pump.
The technical solution used in the present invention is as follows：
A kind of shaping platform of vacuum fast shaping, including frame, the frame is provided with true for cooling down the sizing of section bar
Dead band, the sizing vacuum zone are connected to shaper, and the sizing vacuum zone includes three sections, are followed successively by first from left to right fixed
Type vacuum zone, the second sizing vacuum zone and the 3rd sizing vacuum zone, and they have been connected one to one three settings by pipeline
In the exhaust passage of frame side, three articles of exhaust passages are respectively first exhaust passage, second exhaust passage and the 3rd exhaust and lead to
Road, the first exhaust passage are connected to frequency conversion vavuum pump, and second exhaust passage and the 3rd exhaust passage are each connected to one
Water-ring vacuum pump.
The present invention is different from prior art to be to have carried out subsection setup to the sizing vacuum zone of shaping platform, and per section has
Special vavuum pump carries out vacuumizing setting up negative pressure, such that sizing section can quickly and fully set up negative pressure, Er Qie
The sizing section that first paragraph Vacuum shaping section namely section bar are entered at first employs frequency conversion vavuum pump, and it can realize that rotating speed is adjusted automatically
Section, works as initial period, and frequency conversion vavuum pump fast turn-around, with the negative pressure that most fast speed is set up needed for section bar, reduces start waste product
Rate, after negative pressure is set up, on the basis of good shaping is ensured, frequency conversion vavuum pump can automatically restore to relatively low energy-conservation again
Rotating speed, had so both met section bar and had had just enter into sizing section to its vacuum level requirements, and can reduce again setting up negative pressure vacuumizing
Reducing energy consumption in whole process.
Preferably, length of the length of the first sizing vacuum zone and the 3rd sizing vacuum zone less than the second sizing vacuum zone
Degree.
In the present invention, whole Vacuum shaping Duan Chengsan sections distribution, per section by an exhaust passage and a vavuum pump control
Vacuum, is so disposed to the good shaping for ensureing section bar so that the negative pressure in sizing section is enough so that the flowing of water is more
Plus rapid, so as to accelerate the cooling of section bar.Negative pressure of vacuum in order to ensure frequency conversion vavuum pump tells on, and it is first true that it is responsible for
Empty sizing section is unsuitable long, and the second Vacuum shaping section use common water-ring vacuum pump it in order to ensure section bar the
Can continue steadily to be cooled down after one-step cooling, therefore the present invention arranges more long point.
Preferably, three sections of sizing vacuum zones side is provided with and its one-to-one exhaust passage, and the exhaust is led to
Road is connected with the bleeding point of vavuum pump, and the exhaust outlet of vavuum pump has been all connected with gas sampling passage.
Preferably, three exhaust passages include tilting section and the vertical section for connecting as one from top to bottom, incline
Section connects corresponding sizing vacuum zone by guiding valve and pipeline, and vertical section connects corresponding vavuum pump by pipe joint.
Preferably, the tilting section and vertical section are hollow, and vertical section is square structure.
In the present invention, exhaust passage is set to hollow-core construction, and vertical section can be with shaping platform frame more for square structure
Stick on conjunction compact, and it is difficult to make aqueous vapor helical swirl to be produced in passage compared with cylindrical structural, it is to avoid aqueous vapor generation
The noise that causes of enormous impact of the whirlpool in passage.
Preferably, the gas sampling passage is square hollow-core construction.
Preferably, the frequency conversion vavuum pump and with the second sizing vacuum zone and the 3rd sizing be connected respectively two of vacuum zone
Water-ring vacuum pump is arranged side by side.
Three vavuum pumps of the present invention are arranged side by side that installation is more convenient rationally, and their water ring flow control can be unified
Carry out rationally arranging control, do not result in shaping platform component layouts chaotic.
Compared with prior art, the device have the advantages that：
The negative pressure that it can be set up needed for section bar with most fast speed, reduce start percent defective, it is ensured that section bar good cold
But it is molded, and reduces the energy consumption of vavuum pump；Avoid exhaust and produce huge noise；Vavuum pump is rationally distributed.
