Description

Rubber parts extrusion device

Technical field

The utility model relates to a kind of extrusion device, is specifically related to a kind of rubber parts extrusion device.

Background technology

At cover tire, manufacture field, the semi-finished product that consist of rubber mixture mutually combine after producing.Because products temperature and make the difference of its rubber mixture character, often meets difficulty when in tire manufacture, a kind of goods adhere on another goods.The long-term way of using of manufacturers is that the rubber solutions being dissolved in 15 organic solutions is coated onto on a kind of goods.Due to environmental protection, try hard to limit the use of this solution at present.So new method of must seeking help.A kind of way is, puts the extremely strong rubber of one deck bonding force as thin as a wafer between the two-layer goods that will bond, and is often called connection compound.Moreover this connection compound is applied to repair industry over a long time, the link between the carcass of realization sulfuration and new tread.

In order such one deck glue goods to be placed directly in to the discharging opening of extrusion device, particularly constant in order to make to connect temperature, thickness and other property preservations of compound, and from industrial point, the very thin band of directly producing energy coating member overall with is particularly advantageous.Therefore, for example, in order to manufacture the tire recapping, people will produce that width is identical with the Outer Tyre of renovation by fair means or foul, the band of the approximately a few tenths of millimeter of thickness.

In addition, also seek to make the cover tire manufacture of tire more and more accurate.The accuracy of manufacture depends primarily on the situation about conforming to of rubber size, is particularly assembled into the width of goods and the precision of thickness and the stability that form Outer Tyre.Known rubber extruding equipment has several.

Extruder has the one or more extrusion screw rod that leads to storage cavity conventionally, and it can deliver to extrusion cavities by sizing material.Extrusion equipment is divided into two classes-be conventionally called the extruder of roller die head extruder, and the extrusion board that is characterized in them is to consist of the roller outer surface matching with fixation wall.So-called rectangular shape of the mouth as one speaks extruder, is characterized in that extrusion board consists of fixed head.These two kinds of extruders can be extruded very long goods, and its thickness is constant, and the advantage of all kinds of molding machines is same.No matter be which class extruder, the width of the band of extruding is limited by extrusion screw rod diameter all, or if any several extrusion screw rods, is subject to the restriction of extrusion screw rod centre-to-centre spacing.This be because, as fruit product width and extrusion cavities width thus more much bigger than this diameter, have and enough compounds are fed to the supply problem at plate place with correct transporting velocity, also have compound to rest on difficulty in plate and compound, pressure, the assignment problem of transporting velocity on the whole width of extrusion cavities.

These difficult problems of equipment can limit the getable width of goods.Because the industrial machine that requires is done compactly, limited the size of extrusion screw rod, thereby width is more restricted.

In addition, due to the poor fluidity of sizing material, can be by mould crimp.Because workpiece is larger, can not the disposable die cavity that fills up, gas can not arranged in die cavity, when sizing material is joined in die cavity, can produce bearding, and in use, rubber parts mould can be torn from bearding.

Utility model content

The problem that the utility model exists for above-mentioned prior art makes improvements, be that the technical problems to be solved in the utility model is to provide a kind of rubber parts extrusion device, this rubber parts extrusion device can be realized polygon extruding, and can diagonal angle material extrusion, make sizing material stressed even in die cavity, can be by the orderly discharge die cavity of gas.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

A kind of rubber parts extrusion device, comprise extruder, be located at extruder end charging aperture and discharging opening, be located at rubber parts mould, rotary rollers in extruder, the V font mold that described rubber parts mould is hollow, described rotation rod comprises the warm-up mill of being located on described rubber parts mould and is located at pressure roll, jockey pulley, the backing roll in described rubber parts mould.

As preferably, described pressure roll, jockey pulley are located at respectively the two ends of described rubber parts mould, and described backing roll is located at the middle part of described rubber parts mould.

As preferably, the thickness of described rubber parts mould is 70 ㎜.

As preferably, the width of described rubber parts mould is 1800-2200 ㎜.

As preferably, the charging angle of described charging aperture is 120-180 °.And in prior art, charging angle is generally 90 °, cause the power of squeezing excessive, die cavity discontinuity.

The utility model has the advantage of the drawback that has overcome prior art, the bubble that inside workpiece forms without technique, material internal structure is consistent, without tomography; Take the material extrusion simultaneously of a plurality of crowded material mouths, be once extruded into an Exhaust Gas, and make the pressure in die cavity basically identical with secondary pressurized, prevented the generation of glue-lines; Reduce sizing material flow resistance, improve the mobility of sizing material while extruding; The position of change crowded material mouth, strengthens feeding angle; Greatly saved raw-material consumption in production process.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
