The weak point of this structure is:
1. axis system is too complicated, and needing superhigh pressure pretension extruding wheel shaft is 19, changes squeegee roller 20 inconveniences.
2. squeegee roller 20 diameter dimensions are large, and cost is high, and the extruding production cost is high.
3. because the effect that main shaft bears driving torque and the dual load of extruding radial power causes Main Shaft Service Life short.
4. temperature gradient is large in squeegee roller 20 courses of work, and the life-span is short.
5. main shaft can not be long, bearing supports that spacing can not be excessive, otherwise radial compression power can cause main shaft to produce huge moment of flexure and destroy, and therefore can not realize that the wide multiple-grooved (more than 3) of taking turns is continuously extruded, and this mode is to realize the optimal selection of wide and flat production.
For continuous coating, because squeegee roller 20 diameters are large, the working portion of die cavity 9 and mould 13 are difficult to layout, cause the runner of extrusion metal long, and resistance is large, and energy consumption is large.
Summary of the invention
The object of the invention is to address the above problem, a kind of continuous extruder with backing roll is provided, simple in structure, security performance improves, and reduces use cost.
The technical scheme that the present invention adopts for achieving the above object is: a kind of continuous extruder with backing roll, relate to compression roller and die cavity are housed on the frame, have chute on the frame, compression roller and backing roll are installed in the chute, load applying is on compression roller, backing roll is arranged in the direction upper support relative with load on press roll surface, compression roller compresses with backing roll and contacts, the reduced that the diameter of compression roller is compared existing squeegee roller is a lot, length lengthens a lot, and the backing roll diameter dimension is greater than the compression roller diameter dimension.
Described hydraulic jack drives and connects die cavity pretension piece, die cavity pretension piece pretension die cavity and compression roller, and the gap that keeps suitable between die cavity and the compression roller is constant.
Installation mold in the described die cavity, mould adopts extrusion die or coating mould.
The continuous extruder of band backing roll of the present invention, the radial load of compression roller can be born by backing roll, so that the diameter of compression roller is compared the reduced of existing squeegee roller is a lot, length lengthens a lot, this structural change of compression roller brings a lot of advantages:
1. extruding wheel shaft system is simplified, and the complicated operations such as hydraulic nut that originally need to change no longer need.
2. owing to no longer needing superhigh pressure pretension extruding wheel shaft system, so that the fail safe of the operation of equipment and running improves greatly.
3. compression roller belongs to frock class consumable accessory, because significantly reducing of size reduces so that use cost is corresponding.
4. it is more reasonable that the application of backing roll makes the stress of compression roller, and load no longer is the alternating force effect, reduced intensity tired, the creep equivalent damage, and frock is increased useful life.
5. needn't adopt very large diameter compression roller, the use of path compression roller is so that the circumference of compression roller race is heated evenly the probability of the Thermal Fatigue Damage of reduction again.
6. what compression roller can design is very long, use for the charging of many bars like this and become possibility, mean original in the fertile super wide product of ability on the super large continuous extruder, just can realize with very low energy consumption and very low frock loss at small extruding machine now, reduced production cost, economic benefit is very remarkable.
7. this structure can have two kinds of mode of operations namely to coat and push, one-machine-multi-function.The path compression roller substitutes conventional extruded wheel shaft system, so that the reduction of frock practical cost, and demolition and maintenance are very convenient.
