Abstract
The utility model discloses a raw material coring device of a polyurethane foaming machine, whose constitute units comprise a coring device, a densimeter, an air inlet and a conveying pump component, wherein the densimeter and the air inlet are connected with a gas inlet of the coring device, and the conveying pump component is connected with the input of the densimeter; an outlet of the coring device and the conveying pump component are respectively correspondingly communicated with the top end and the bottom of a polyether polyol raw material tank; the constitute units are mutually connected through pipelines; and the output of the densimeter is connected with a control unit of the coring device. The raw material coring device of the polyurethane foaming machine can core the polyether polyol raw materials, so that the mould filing quality and the surface quality of the product can be improved for producing a self-crusting automobile steering wheel or a self-crusting polyurethane foaming product; therefore, the foams of the foaming plastic are compact and uniform, and the product quality is greatly improved.
Description
Technical field
The utility model relates to a kind of raw material coring device, relates in particular to a kind of in the industry about making the raw material coring device of polyurethane from the used foaming machine of skinning vehicle steering or other polyurethane skinned foam goods.
Background technology
Under the existing routine techniques; Make polyurethane and use two kinds of raw materials from skinning vehicle steering or other skinned foam goods; Be respectively PPG and isocyanates; These two kinds of raw materials are placed apart in two batch cans, after mixing in the control arrival hybrid gun head through measuring pump, filter in pipeline separately, are injected in the mould then and produce.At present, still needleless adopts the coring technology to be applied among foaming makes to the PPG raw material.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is the coring device that proposes a kind of polyurethane polyureas ethoxylated polyhydric alcohol, to improve the quality of foam production products obtained therefrom.
The technical solution of the utility model is; A kind of raw material coring device of polyurethane foaming machine; It constitutes the unit and comprises coring device, the densitometer and the air intlet that link to each other with coring device air inlet; And the delivery pump assembly that links to each other with densitometer input, characteristics are: the delivery outlet of said coring device and delivery pump assembly respectively with the corresponding connection in top and bottom of the PPG head tank of polyurethane foaming machine, each constitutes, and to pass through pipeline between the unit continuous; And said densitometric output links to each other with the control module of coring device.
Further; The raw material coring device of above-mentioned polyurethane foaming machine; Wherein: said coring device is multiple tooth stirring foaming type coring jar; Motor and magnetic shaft coupling are equipped with in said coring jar upper end, and the stator and the rotor of multiple tooth shape are housed in the coring jar, and motor rotates in the driving down coversion of coring device control module; Said density is counted the riser type densitometer.
The utility model is applied to the polyurethane high pressure foaming machine with raw material coring technology; Through the PPG raw material is carried out coring; For producing from skinning vehicle steering or polyurethane foamed product from skinning; Can improve and fill mould quality and surface quality of products, make the not only densification but also even of abscess of foamed plastics, improve product quality greatly.
Description of drawings
Fig. 1 is the syndeton sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
As shown in Figure 1, be the syndeton sketch map of the raw material coring device of the utility model polyurethane polyureas foaming machine.As shown in the figure, the formation unit of this coring device comprises coring device 1, the densitometer 2 and the air intlet 3 that link to each other with coring device air inlet 11, and the delivery pump assembly 4 that links to each other with densitometer 2 inputs.Wherein, The delivery outlet 12 of coring device 1 and delivery pump assembly 4 are respectively with the top of the head tank 5 of PPG and the bottom is corresponding is connected; Each constitutes between the unit through pipeline 6 and links to each other, and this densitometer 2 be the riser type structure, and it exports link to each other with the control module of coring device (not shown).
Especially, this coring device is multiple tooth stirring foaming type coring jar, and motor and magnetic shaft coupling are equipped with in coring jar upper end, and the stator and the rotor of multiple tooth shape are housed in the coring jar, and motor rotates in the driving down coversion of coring device control module.
Above-mentioned coring device adds the PPG raw material in the head tank 5 to when real work, and PPG is delivered to it in coring jar through the delivery pump assembly; Under the situation of bubbling air; Make PPG in the coring jar, fully contact, after the gas concentration that its foamable reaction is produced surpasses the balance saturated concentration, in material system, begin to form micro-bubble with air; And the raw material of the coring in this coring device entered in the head tank circulate; Detect PPG and Air mixing ratio in the head tank through densitometer, just detect the density of the PPG after the coring, control the opening and closing of coring device through the data that detect; Make the interior PPG of its whole head tank all through the coring of coring jar, to satisfy the requirement of producing many raw materials mixed proportion.PPG and these two kinds of raw materials of isocyanates of coring are placed apart in two head tanks, through after mixing in measuring pump, the filter arrival hybrid gun head, be injected in the mould then and produce in each comfortable pipeline.
The utility model is through to the coring of PPG raw material and be applied to the polyurethane high pressure foaming machine; For producing from skinning vehicle steering or polyurethane foamed product from skinning; Can improve and fill mould quality and surface quality of products; Make the not only densification but also even of abscess of foamed plastics, improved product quality greatly.
