Abstract
A polyurethane high-pressure foam machine is provided. A high-pressure metering pump utilizes the high speed generated from high pressure to fully blend the two groups of raw materials inside a blending head, then injects the blended materials into a test chamber for foaming, remainder materials are eliminated out by a push bar inside the blending head. The high-pressure metering pump is connected with a mainframe via a high-pressure rubber hose at the outlet of a filter. The foam machine can disuse the solvent for cleaning and is conducive to environment protection and to the health of operators; the service life of the blending head is prolonged with high-quality products attained.
Description
The utility model belongs to the plastic molding machinery apparatus field, specially refers to a kind of high pressure foaming machine of polyurethane.
Polyurethane foam plastics is made up of the liquid material of two kinds of components, deposits separately at ordinary times, during production, by conveying, metering, mixing, the injection of a covering device, finishes chemical reaction very soon, condenses into the solid state foam body.Its market that has a wide range of applications is as insulation, sound insulation, purposes such as shockproof.In existing similar heavy chemicals plant equipment, as the low pressure foaming machine, be very ripe equipment, but on process production line, owing to its mixing is to be finished by the agitator high-speed stirred in the teeter chamber of mixing head, in the teeter chamber and agitator on residual compound in time remove, therefore requisite will have the process of together mixing head being cleaned, to repeatedly clean with certain amount of organic solvent, could drop into use next time, organic solvent contains volatile component and harmful components, serious harm workers ' health and pollution workshop condition, and easily breaking out of fire, thereby the foaming machine of this low pressure type influences it owing to matting is indispensable and promotes the use of.For this reason, we work out the strength by high-pressure pump repeatedly, adopt the operation remove residual mixture in the hybrid chamber voluntarily, replaced in the past must be through the way of solvent clean, not only clean mixing head but also satisfied environmental requirement, and prolonged the service life of mixing head.
The purpose of this utility model, be many defectives such as operating personnel's injury and to be redesigned a kind of high pressure foaming machine that need not the solvent clean operation in order to overcome existing low pressure foaming machine requisite environmental pollution that is brought with the organic solvent matting when the operation.
The utility model relies on following technical proposals to realize, a kind of polyurethane high pressure foaming machine, comprise two groups of material basins that are respectively arranged with attemperating unit and be separately positioned on filter on the path, it is characterized in that, be connected to the high-pressure metering pump of main frame respectively by high-pressure rubber pipe by the filter outlet place, by the high-low pressure switching valve, be connected to mixing head by one road pipeline by pumping hole respectively, turn back to material pot through another road pipeline.
Described two groups of material basins are provided with temperature control equipment in its outside, are material in the basin can be heated and the Cooling Control device.
It is the high-low pressure switching valve that drives by variable speed electric motors, particularly for described high-pressure metering pump, and it is to drive by hydraulic system.
Hydraulic system is combined into by fuel tank, oil pump, overflow valve, accumulator and magnetic valve.It provides hydraulic oil for mixing head and high-low pressure switching valve, finishes the instruction change action, relies on the control of this switching valve to make complete machine be in low pressure recycle state or cycle of higher pressure state.
Described mixing head, it is the core of this device, comprises the mixing chamber of a tubular, and indoor have an interlayer, and the center is a band handle piston, and muzzle is arranged at the bottom, and chamber is in recurrent state or inject state.Recurrent state is to collide mutually with ceiling capacity to be mixed in mixing chamber, and inject state is that control piston stops the component collision, and the total overall reaction compound is released mixing chamber, does not stay any defective material.The effect of mixing head is two groups of stostes that high-pressure metering pump is transported, fiercely collision in the cylindrical shape hybrid chamber, even mixed foaming moulding of moment relies on and the close-fitting piston push rod of mixing head inner chamber after this injection process is finished, and clean hybrid chamber is removed in the raffinate release.
Injection process is the mixing head opening action, and the length of opening the time is by the time relay control of device in electrical control cubicles, and the equipment repeat circuit can be provided with four, and its selector switch is arranged on the electrical control panel.Control the four kind injection volumes of 0.01-99.99 between second respectively.
The positive benefit of this device polyurethane high pressure foaming machine is a high speed of utilizing high pressure to produce, and two groups of raw materials are fully mixed in mixing head, injects die cavity, foaming, and defective material is removed away automatically by the push rod in the mixing head.The operation that this machine has been exempted aborning with solvent clean helps environmental requirement, also helps operator's health, and when obtaining same quality product, extended the service life of mixing head.
Further specify embodiment below in conjunction with accompanying drawing:
Description of drawings:
The workflow block diagram that Fig. 1 produces for polyurethane product;
Fig. 2 is each part schematic diagram of polyurethane high pressure foaming machine;
Fig. 3 is this foaming machine main frame scheme of installation;
Fig. 4 is the mixing head appearing diagram;
Fig. 5 a is a mixing head recurrent state operation principle schematic diagram;
Fig. 5 b is a mixing head inject state operation principle schematic diagram.
Among the figure, two material basins 1, its outside is respectively equipped with temperature control equipment 2 and filter 3, be connected to high-pressure metering pump 5 and the high-low pressure switching valve 6 that is connected to variable speed electric motors, particularly 4 by high-pressure rubber pipe, the hydraulic means 7 that produces driving force links to each other with them and mixing head 8 respectively, mixing head includes tubular mixing chamber 8.1 again, and indoor downside has interlayer 8.2, and central axis has the discharging muzzle 8.4 of band handle piston 8.3 and lower end; The control section of mixing head piston realizes that by four relays of device in electrical control cubicles 9 selector switch of relay is arranged on the electrical control panel 10.Two kinds of component raw materials of polyurethane, in batch can 1 after the filtration of the regulation and control of temperature-adjusting device 2 and filter 3, by high-pressure metering pump 5, under the control of variable speed electric motors, particularly 4, press formula rate, be transported to high-low pressure switching valve 6, at this moment, operational order is low pressure recycle in this way, and two groups of raw materials then low pressure return; Feed back jar 1, operational order is high-pressure injection in this way, two groups of then straight-through mixing heads 8 of stoste, shown in Fig. 5 b, the mixing head push rod is under the driving of the hydraulic oil that hydraulic system 7 provides, and is up immediately, and circulation canal blocking-up injection channel is freely opened, two groups of stostes swash simultaneously at the nozzle place penetrates high velocity impact, and moment finishes and is mixed into die cavity.And the time length of foam-injection, by being located at the electrical control meticulous control of time control instrument cashier's office in a shop, time one arrives, and stops injection automatically, and mixing head 8 is shown in Fig. 5 a, push rod is descending, remaining feed liquid is pushed bar and releases hybrid chamber, has finished shot foaming operation, when foaming once more, as long as give its instruction of a foam-injection again, all repeat down again.
