Description
Technical field
The utility model relates to the mixing head for polyurethane combined material automatic blending.
Background technology
Polyurethane (being called for short PU) is the abbreviation of polyurethanes, and English name is polyurethane, and it is a kind of macromolecular material.Polyurethane is a kind of emerging high-molecular organic material, is described as " the fifth-largest plastics ", is widely used in national economy various fields because of the performance of its brilliance.Product applications relates to light industry, chemical industry, electronics, weaving, medical treatment, building, building materials, automobile, national defence, space flight, aviation .... progressively replace conventional vulcanized rubbers and be applied to many fields; And polyurethane is the polymer be made up of polyisocyanates (black material ISO) and PPG or the raw material such as chain extender or crosslinking agent (expecting POLY in vain) such as PEPA and/or small molecule polyol, polyamine or water; By feed change kind and composition, product form and performance thereof can be changed significantly, obtain from softness to hard final products.Existing polyurethanes technology is all filled a prescription by people and is measured PPG or the raw material such as chain extender or crosslinking agent such as PEPA and/or small molecule polyol, polyamine or water and forms white material (POLY) and heated by polyurethane casting machine with black material (ISO), precisely to measure and high-speed stirred forms final products.Above this white material (POLY) by artificial process of filling a prescription and measure, because each link adopts human metering to complete processing substantially, cause inefficiency, manpower and material resources are wasted seriously, also there is metering error to a certain extent, affect the performance of final products.
Utility model content
The utility model, for the problems referred to above, provides a kind of mixing head for polyurethane combined material automatic blending, can precisely measure and control inlet amount, reduces human error and human cost, Improving The Quality of Products.
For this reason, the utility model takes following technical scheme, for the mixing head of polyurethane combined material automatic blending, its feature is comprising head, the middle part of head arranges shaft, the bottom of shaft arranges agitator, head is arranged the flow of multiple material-feeding needle valve system in order to regulate raw material to enter head.
The top of described head arranges control valve square, and control valve square top arranges feedback outlet and charging aperture, and the periphery of described control valve square arranges multiple return pressure device, and return pressure device comprises recalls to pressure valve bar.
Described material-feeding needle valve system comprises needle-valve cylinder, and the bottom of needle-valve cylinder sets gradually needle-valve, needle-valve body and needle-valve plug.
The periphery of head also arranges cleaning needle valve system, it comprises adjusting bolt, adjusting nut, the bottom of adjusting bolt sets gradually spring and cleaning needle-valve, the outer setting cleaning valve pocket of cleaning needle-valve, the rear portion of cleaning valve pocket arranges cleaning valve seat, and described cleaning valve puts and arranges air inlet, and described cleaning valve seat is provided with cleaning fluid import.
The mixing head that the utility model utilizes needle valve mechanism to design, will clean, and material feeding, the mixing of raw material High Rotation Speed integrate, and also have feedback outlet, reduces material loss, simplifies technical operation flow, decreases the error of artificial batching, improves quality of finished.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.
Mixing head as shown in Figure 1 comprises shaft 1, locking nut 2, bearing gland 3, upper ditch ball bearing 4, adapter sleeve 5, lower bearing 6, bearing holder (housing, cover) 7, return pressure device 8, material-feeding needle valve system 9, agitator 10, goes out funnel 11, control valve square 12, head square 13, cleaning needle valve system 14, stir cover 15, funnel locknut 16.
Cleaning needle valve system as shown in Figure 2 comprises adjusting bolt 14-1, adjusting nut 14-2, cleaning valve adjustable cap 14-3, cleaning valve spring cup 14-4, spring 14-5, cleaning needle-valve 14-6, cleaning valve pocket 14-7, cleaning valve seat 14-8.
Material-feeding needle valve system as shown in Figure 3 comprises needle-valve cylinder 9-1, needle-valve 9-2, needle-valve body 9-3, needle-valve plug 9-4.
Raw material is delivered to mixing head by metering system by multiple mixing batch can simultaneously, and motor, through V belt speedup or frequency control, makes mixing head High Rotation Speed in hybrid chamber, is fully mixed by 11 kinds of raw materials.The charging aperture of mixing head is according to actual flow needs, and access corresponding aperture high-strength anti-corrosion four fluorine tube, other one end is connected with metering system discharging interface.Discharging opening is according to actual flow needs, and access corresponding aperture high-strength anti-corrosion four fluorine tube, the other end is connected with blending tank feed back joint.
As shown in Figure 4, cleaning needle-valve operation principle: air admission hole H is not when ventilating, and clean-out opening is cleaned needle-valve and blocks, when air admission hole H ventilates, cleaning needle-valve is opened, and cleaning fluid G hyperbar from clean-out opening enters stirring cover and rinses hybrid chamber.
As shown in Figure 5, material feeding needle-valve operation principle: when the logical upper gas of the first source of the gas K, material hole blocks by needle-valve, the raw material of charging aperture I from back material hole J out, when the logical upper gas of the second source of the gas L, needle-valve is opened material hole and is blocked by back material hole simultaneously, and now the raw material of charging aperture I just can inject hybrid chamber from material hole.Recall to flowing pressure principle: recall to pressure valve bar and change feedback outlet size by rotating and adjust charging and feed back isostasy.
Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
