Description

A kind of cooling device of bar plastic

Technical field

Technical field of plastic processing machinery is the utility model is related to, more particularly to a kind of cooling device of bar plastic.

Background technology

Plastic extruder is heated raw material, melting, after plastic extruder extrudes, the extrusion molding from its head Bar plastic, bar plastic after supercooling enter arrives pelleter, given size is made in bar plastic by pelleter Plastic pellet.Cooling device plays the important and pivotal role in modified plastics extruding pelletization production line.Existing bosh It is difficult to the requirement for meeting technical cooling, especially in the case where the temperature difference is larger, the bar plastic temperature of extrusion is higher, water temperature Also it is higher, the difficulty of the processes such as follow-up pelletizing can be increased, in some instances it may even be possible to influence the appearance and performance of plastic pellet.

But by lengthening, widening or deepen bosh, to increase the volume of cooling water, though cooling capacity can be increased. But lengthen or widening bosh will make whole extruding pelletization production line lengthen or widen, so as to cause to waste, and limit The area of extruding pelletization production line.Especially at some in special circumstances, normal cooling device is unable to reach requirement, have impact on modeling Expect the product quality of particle.

The content of the invention

The purpose of this utility model is that, there is provided a kind of good cooling results, the high modified plastics of plastic pellet product quality The cooling device of the bar plastic of extruder extrusion.

A kind of cooling device of bar plastic, including bosh and stent, in the horizontal peace of the madial wall of bosh Equipped with multigroup pressure roller, multigroup pressure roller is interspersed with not contour underwater penetration, forms wave arrangement；Further include Bellows, the bellows are composed of upper bellows, the lower bellows connected respectively with wind turbine, and are separated by partition plate, upper bellows with The ventilating duct passed through for plastic strip is equipped between lower bellows, the plastic strip is guided by guide roller.

The shape of the bosh is in the cuboid of open topped, and a pair is equipped near the feeding mouth of lower bellows Brush roll, bellows are equipped with multiple ventilation holes, and the wind turbine is connected by herringbone ventilation duct with bellows.

A kind of cooling device of bar plastic described in the utility model, its advantage are：

(1) dried up by water cooling and wind-heat, the cooling effect of bar plastic can be significantly improved, bar plastic after cooling is just Processed in subsequent handling, improve the stability of product, and achieveed the purpose that to improve plastic pellet product quality；

(2) floor space can be reduced, it is simple in structure, cost input is reduced, it is simple to be applicable in；

(3) due to cooling down, being heated evenly, prepared bar plastic can be easily reached plastic pellet production technology will The defects of asking.

Brief description of the drawings

Fig. 1 is a kind of structure diagram of the cooling device of bar plastic.

Figure label explanation：

1 is bosh, and 2 be stent, and 3 be pressure roller, and 4 be bellows, and 5 be upper bellows, and 6 be lower bellows, and 7 be wind turbine, 8 be every Plate, 9 be plastic strip, and 10 be ventilating duct, and 11 be guide roller, and 12 be brush roll, and 13 be ventilation hole, and 14 be herringbone ventilation duct, 15 It is plastic extruder for feeding mouth, 16,17 be plastics stock-cutter.

Embodiment

To describe technology contents, construction feature, institute's reached purpose and effect of the utility model in detail, reality is hereby enumerated below Apply example and coordinate attached drawing to be explained in detail.

A kind of cooling device of bar plastic as shown in Figure 1, a kind of cooling device of bar plastic, including bosh 1 and stent 2, multigroup pressure roller 3 is horizontally installed with the madial wall of bosh 1, multigroup pressure roller 3 enters water with not contour Depth is interspersed, and forms wave arrangement；Further include bellows 4, the bellows 4 are by the windward that is connected respectively with wind turbine 7 Case 5, lower bellows 6 are composed, and are separated by partition plate 8, are equipped with what is passed through for plastic strip 9 between upper bellows 5 and lower bellows 6 Ventilating duct 10, the plastic strip 9 are guided by guide roller 11.

The shape of the bosh 1 is in the cuboid of open topped, is equipped near the feeding mouth 15 of lower bellows 6 A pair of of brush roll 12, bellows 4 are equipped with multiple ventilation holes 13, and the wind turbine 7 is connected by herringbone ventilation duct 14 with bellows 4.

Concrete technology flow process is：Plastic strip 9 is extruded by plastic extruder 15, is cooled down into bosh 1, passes through pressure roller 3 After reducing frictional force, cool drying in bellows 4 is returned, is finally led into plastics stock-cutter 16, chopping is granulated.

In conclusion the only preferred embodiment of the utility model, does not limit the scope of protection of the utility model with this, it is all The equivalent changes and modifications made according to the utility model patent scope and description, is all what the utility model patent covered Within the scope of.
