Description
Technical field
The present invention relates to a kind of extrusion device, be specifically related to a kind of rubber parts extrusion device.
Background technology
Manufacture field at cover tire, mutually combine after the semi-finished product production formed by rubber mixture.Because products temperature and make the difference of its rubber mixture character, often meet difficulty when in the tire manufacture, a kind of goods adhere on another goods.The long-term way of using of manufacturers is that the rubber solutions be 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 often is called the 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 for temperature, thickness and other property preservations that makes to connect 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 recapped, 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, particularly is assembled into the width of the goods that form Outer Tyre and precision and the stability of thickness.Known rubber extruding equipment has several.
Extruder has the one or more extrusion screw rod that leads to storage cavity usually, and it can deliver to extrusion cavities by sizing material.Extrusion equipment is divided into two classes-usually be 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 matched with fixation wall.So-called rectangular shape of the mouth as one speaks extruder, be 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 the extrusion screw rod diameter all, or is subject to the restriction of extrusion screw rod centre-to-centre spacing if any several extrusion screw rods.This be because, as more much bigger than this diameter as the extrusion cavities width that the fruit product width reaches thus, 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, the rubber parts mould can be torn from bearding.
Summary of the invention
The problem that the present invention is directed to above-mentioned prior art existence makes improvements, be that the technical problem to be solved in the present invention is to provide a kind of rubber parts extrusion device, this rubber parts extrusion device can be realized polygon extruding, and can the diagonal angle material extrusion, make sizing material stressed even in die cavity, discharge die cavity that can gas is orderly.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of rubber parts extrusion device, comprise extruder, be located at the 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, the charging angle is generally 90 °, cause the power of squeezing excessive, the die cavity discontinuity.
The invention has the advantages that the drawback that has overcome prior art, the bubble that inside workpiece forms without technique, the material internal structure is consistent, without tomography; Take the material extrusion simultaneously of a plurality of crowded material mouths, once be extruded into an Exhaust Gas, and make the pressure in die cavity basically identical with secondary pressurized, prevented the generation of glue-lines; Reduce the sizing material flow resistance, improve the mobility of sizing material while extruding; The position of change crowded material mouth, strengthen the feeding angle; Greatly saved raw-material consumption in production process.
The accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms the part of specification, for explaining the present invention, is not construed as limiting the invention together with embodiments of the present invention.In the accompanying drawings:
Fig. 1 is the rubber parts extrusion device signal of one embodiment of the present invention;
Fig. 2 is rubber parts extrusion device sizing material flow curve schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, 2, the present invention discloses a kind of rubber parts extrusion device, comprise extruder, be located at the extruder end charging aperture and discharging opening, be located at rubber parts mould 1, rotary rollers in extruder.The V font mold that rubber parts mould 1 is hollow, this design makes the present invention realize polygon material extrusion, and can the diagonal angle material extrusion, make sizing material in mould stressed evenly, the orderly discharge by gas.
Rotating rod comprises the warm-up mill 2 of being located on rubber parts mould 1 and is located at pressure roll 4, jockey pulley 3, the backing roll 5 in rubber parts mould 1.
