Description
Technical field
The present invention relates to a kind of drawing mechanism, relate in particular to a kind of pearl wool foaming machine drawing mechanism.
Background technology
The polyethylene foam cotton is the non-crosslinked hole-closing structure, claims pearl cotton (EPE) again, is a kind of packaging material of novel environment friendly.It produces countless separated foams by low density polyethylene (LDPE) fat through physical blowing and constitutes; Overcome that common foamed glue is frangible, the shortcoming of distortion, recovery difference; Have advantages such as water proof protection against the tide, environmental protection, plasticity be strong; Also having good chemical resistance, is the ideal substitute of Traditional Packing material, is widely used in the packing of products such as electronic apparatus, household electrical appliances, articles for daily use.After adding antistatic agent and fire retardant, more show its remarkable performance.
Existing pearl wool foaming machine comprises spice machine and two parts of extruder; The spice machine is used for regrown material and virgin material are evenly mixed; And extruder mainly is the extrusioning shaping that is used as product; Wherein include drawing mechanism in the extruder, drawing mechanism comprises discharge nozzle and die orifice, and the effect of die orifice is that the pearl cotton is produced typing.Present pearl cotton is when producing, and the pearl cotton comes out from discharge nozzle, through the die orifice typing, after the apparatus for supercooling cooling, transfers out again, accomplishes and produces.The cotton surface irregularity of the pearl of producing like this, roughness is big, and the quality of production does not reach requirement.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed the smooth pearl wool foaming machine drawing mechanism of the cotton surfacing of pearl that a kind of assurance is produced.
Technical solution of the present invention is achieved in that a kind of pearl wool foaming machine drawing mechanism, comprises discharge nozzle and die orifice, and said discharge nozzle peripheral hardware is useful on the hold down gag of typing.
Preferably, said hold down gag comprises terminal pad, bearing, compression plate and snap ring; Said discharge nozzle is provided with first step and groove; Said terminal pad is enclosed within outside the discharge nozzle, and with first step near; Be provided with bearing between said terminal pad and discharge nozzle; Said compression plate is enclosed within outside the discharge nozzle, with terminal pad through being threaded together; Leave the gap between said compression plate and discharge nozzle; Be provided with snap ring in the said groove; Be provided with second step in the said terminal pad; Said snap ring and second step near.
Preferably, the upper surface of said compression plate is the arc surface that caves inward.
Preferably, the junction of the upper surface of said compression plate and centre bore is provided with circular arc.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of pearl wool foaming machine drawing mechanism of the present invention, during use, the compression plate rotation because the effect of fixed connection dish is played in the existence of snap ring and first step, makes terminal pad not move, compression plate will move to the die orifice direction, and forms the gap between die orifice.The pearl cotton is when producing, and the pearl cotton comes out from discharge nozzle, comes out in the gap between compression plate and die orifice, has guaranteed cotton surface smooth degree of the pearl of producing and flatness like this, has improved the quality of production.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of pearl wool foaming machine drawing mechanism of the present invention;
Accompanying drawing 2 is the user mode structural representation of pearl wool foaming machine drawing mechanism of the present invention;
Wherein: 1, discharge nozzle; 2, die orifice; 3, terminal pad; 4, bearing; 5, compression plate; 6, snap ring; 7, first step; 8, groove; 9, second step; 10, circular arc.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of pearl wool foaming machine drawing mechanism shown in accompanying drawing 1 comprises discharge nozzle 1 and die orifice 2, and said discharge nozzle 1 peripheral hardware is useful on the hold down gag of typing; Said hold down gag comprises terminal pad 3, bearing 4, compression plate 5 and snap ring 6; Said discharge nozzle 1 is provided with first step 7 and groove 8; Said terminal pad 3 is enclosed within outside the discharge nozzle 1, and with first step 7 near; 1 of said terminal pad 3 and discharge nozzle are provided with bearing 4; Said compression plate 5 is enclosed within outside the discharge nozzle 1, with terminal pad 3 through being threaded together; 1 of said compression plate 5 and discharge nozzle leave the gap; Be provided with snap ring 6 in the said groove 8; Be provided with second step 9 in the said terminal pad 3; Said snap ring 6 and second step 9 near; The upper surface of said compression plate 3 is the arc surface that caves inward; The upper surface of said compression plate 3 and the junction of centre bore are provided with circular arc 10.
Of the present invention a kind of pearl wool foaming machine drawing mechanism shown in accompanying drawing 2; During use, compression plate 5 rotations are because the existence of snap ring 6 and first step 7; Play the effect of fixed connection dish 3; Make terminal pad 3 not move, compression plate 5 will move to die orifice 2 directions, and 2 of die orifices form the gap.The pearl cotton is when producing, and the pearl cotton comes out from discharge nozzle 1, comes out in the gap between compression plate 5 and die orifice 2, has guaranteed cotton surface smooth degree of the pearl of producing and flatness like this, has improved the quality of production.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
