Abstract
This utility model provides a kind of gradient bosh being applied to grit maker, and including cell body, described cell body is provided with the high-temperature region near extrusion die and the low-temperature space away from extrusion die, is provided with thermal insulation board between described high-temperature region and low-temperature space；Described high-temperature region is provided with attemperating unit, and described low-temperature space is provided with water inlet and outlet.Plastics flow out from extrusion die, and the high-temperature region and the low-temperature space that sequentially pass through cell body cool down, it is achieved that gradient type is lowered the temperature, it is to avoid cause shrinkage cavity because of plastics quenching, it is ensured that product appearance, improve product quality.
Description
Technical field
This utility model relates to a kind of plastic extruding forming equipment, particularly to a kind of gradient cooling being applied to grit maker
Tank.
Background technology
Grit maker is to be heated by plastic raw materials, is allowed to into glutinous stream mode, under the effect of pressurization, is carried out by extrusion die
Extrusion, is then cooled to strip glassy state, after pellet device, it is thus achieved that the cylindric or machinery of ellipticity plastic grain continuously.
Plastics are usually lowered the temperature with screw clamp during taking out grain.And in temperature-fall period, if plastics self-strength is relatively
Weak, especially PC and PC/ABS, it is easy to cause plastics inner to produce shrinkage cavity owing to cooling extent is too big, cause pelletizing out
Product appearance bad, affect the quality of product.
Summary of the invention
The technical problems to be solved in the utility model is according to above-mentioned the deficiencies in the prior art, it is provided that one is applied to take out grain
Machine, it is possible to improve the gradient bosh of product appearance.
The technical solution of the utility model is as follows:
A kind of gradient bosh being applied to grit maker, including cell body, described cell body is provided with near extrusion die
High-temperature region and the low-temperature space away from extrusion die, be provided with thermal insulation board between described high-temperature region and low-temperature space；Described high-temperature region sets
Being equipped with attemperating unit, described low-temperature space is provided with water inlet and outlet.
Further, described attemperating unit includes heating plate and temperature inductor, described heating plate and described temperature sense
Device is electrically connected with.
Further, described high-temperature region is provided with submerged roller, and described low-temperature space is provided with roller waterborne and submerged roller.
Further, a length of 0.6m-1.0m in described high-temperature region.
Compared with prior art, this utility model has the advantages that plastics flow out from extrusion die, sequentially warp
High-temperature region and the low-temperature space of crossing cell body cool down, it is achieved that gradient type is lowered the temperature, it is to avoid cause shrinkage cavity because of plastics quenching, it is ensured that
Product appearance, improves product quality.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type is described in further detail.
As it is shown in figure 1, the embodiment that this utility model provides, a kind of gradient bosh being applied to grit maker, including
Cell body 10, described cell body 10 is provided with the high-temperature region 11 near extrusion die 30 and the low-temperature space 12 away from extrusion die 30, institute
State and between high-temperature region 11 and low-temperature space 12, be provided with thermal insulation board 13.
Described high-temperature region 11 is provided with attemperating unit 20, and described attemperating unit 20 includes heating plate 21 and temperature inductor
22, described heating plate 21 is electrically connected with described temperature inductor 22.Wherein, temperature inductor 22 is according to water in high-temperature region 11
Temperature, controls the running of heating plate 21, it is ensured that the water temperature in high-temperature region 11 is in set point.
Described low-temperature space 12 is provided with water inlet 14 and outlet 15.Wherein, cold water enters low-temperature space 12 from water inlet 14
And flow out from outlet 15, it is ensured that the water temperature in low-temperature space 12 is in set point.
Described high-temperature region 11 is provided with submerged roller 17, and described low-temperature space 12 is provided with roller 16 waterborne and submerged roller 17.Wherein,
Roller 16 waterborne and submerged roller 17 are for drawing the plastics of strip glassy state.
The described a length of 0.6m-1.0m in high-temperature region 11, the preferred 0.6m of the present embodiment.Certainly, the length of high-temperature region 11 is not
Being only limitted to 0.6m-1.0m, user can arrange shorter or longer according to practical situation.
Plastics flow out from extrusion die 30, and the high-temperature region 11 and the low-temperature space 12 that sequentially pass through cell body 10 cool down, it is achieved
Gradient type cooling, it is to avoid cause shrinkage cavity because plastics quenching, it is ensured that product appearance, improve product quality.
Above disclosed only this utility model preferred embodiment, can not limit this utility model with this certainly
Interest field, the equivalent variations therefore made according to this utility model claim, still belong to the scope that this utility model is contained.
