Description
Technical field
The utility model relates to a kind of drawing mechanism, relates 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 again expanded polyethylene foam (EPE), 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 consists of, overcome that common foamed glue is frangible, distortion, the poor shortcoming of recovery, have the advantages such as water proof protection against the tide, environmental protection, plasticity be strong, also has good chemical resistance, be the ideal substitute of Traditional Packing material, be widely used in the packing of the products such as electronic apparatus, household electrical appliances, articles for daily use.After adding antistatic agent and fire retardant, more aobvious its remarkable performance.
Existing pearl wool foaming machine comprises blender and two parts of extruder, blender is used for regrown material and virgin material are evenly mixed, if and extruder main is used as the extrusioning shaping of product, wherein include drawing mechanism in the extruder, drawing mechanism comprises discharge nozzle and die orifice, and the effect of die orifice is that expanded polyethylene foam is carried out production definition.Present expanded polyethylene foam is when producing, and expanded polyethylene foam from discharge nozzle out by the die orifice typing, transfers out after the apparatus for supercooling cooling again, finishes production.The expanded polyethylene foam surface irregularity of producing like this, roughness is large, and the quality of production does not reach requirement.
The utility model content
The utility model purpose is the smooth pearl wool foaming machine drawing mechanism of expanded polyethylene foam surfacing that provides a kind of assurance to produce in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pearl wool foaming machine drawing mechanism, comprise discharge nozzle and die orifice, and described discharge nozzle peripheral hardware is useful on the hold down gag of typing.
Preferably, described hold down gag comprises terminal pad, bearing, compression plate and snap ring; Described discharge nozzle is provided with first step and groove; Described terminal pad is enclosed within outside the discharge nozzle, and with first step near; Be provided with bearing between described terminal pad and discharge nozzle; Described compression plate is enclosed within outside the discharge nozzle, is threaded connection together with terminal pad; Leave the gap between described compression plate and discharge nozzle; Be provided with snap ring in the described groove; Be provided with second step in the described terminal pad; Described snap ring and second step near.
Preferably, the upper surface of described compression plate is the arc surface that caves inward.
Preferably, the junction of the upper surface of described compression plate and centre bore is provided with circular arc.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of pearl wool foaming machine drawing mechanism of the utility model scheme, during use, the compression plate rotation, because the existence of snap ring and first step is played the effect that is fixedly connected with dish, so that terminal pad can not move, compression plate will move to the die orifice direction, and forms the gap between die orifice.Expanded polyethylene foam when producing, expanded polyethylene foam from discharge nozzle out, the gap between compression plate and die orifice has out guaranteed smoothness and the flatness on the expanded polyethylene foam surface of producing like this, has improved the quality of production.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 2 is the use status architecture schematic diagram of pearl wool foaming machine drawing mechanism of the present utility model;
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
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of pearl wool foaming machine drawing mechanism as shown in Figure 1 comprises discharge nozzle 1 and die orifice 2, and described discharge nozzle 1 peripheral hardware is useful on the hold down gag of typing; Described hold down gag comprises terminal pad 3, bearing 4, compression plate 5 and snap ring 6; Described discharge nozzle 1 is provided with first step 7 and groove 8; Described terminal pad 3 is enclosed within outside the discharge nozzle 1, and with first step 7 near; 1 of described terminal pad 3 and discharge nozzle are provided with bearing 4; Described compression plate 5 is enclosed within outside the discharge nozzle 1, is threaded connection together with terminal pad 3; 1 of described compression plate 5 and discharge nozzle leave the gap; Be provided with snap ring 6 in the described groove 8; Be provided with second step 9 in the described terminal pad 3; Described snap ring 6 and second step 9 near; The upper surface of described compression plate 3 is the arc surface that caves inward; The upper surface of described compression plate 3 and the junction of centre bore are provided with circular arc 10.
Described in the utility model a kind of pearl wool foaming machine drawing mechanism as shown in Figure 2, during use, compression plate 5 rotations, because the existence of snap ring 6 and first step 7, play the effect that is fixedly connected with dish 3, so that terminal pad 3 can not move, compression plate 5 will move to die orifice 2 directions, and 2 of die orifices form the gap.Expanded polyethylene foam when producing, expanded polyethylene foam from discharge nozzle 1 out, the gap between compression plate 5 and die orifice 2 has out guaranteed smoothness and the flatness on the expanded polyethylene foam surface of producing like this, has improved the quality of production.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
