CN203646407U - Compound roll - Google Patents

Abstract

The utility model provides a compound roll which is mainly applied to a dough mixing step of flour product processing. The compound roll comprises a first shaft head, a second shaft head and a roll body centrifugally cast from two metals, wherein the roll body is formed by sleeving an alloy cast iron roll body to a grey cast iron roll body, and flanges for avoiding a dough band from leaking out are arranged at the two ends of the roll body. The compound roll is mainly applied to the dough mixing step of the flour product processing; as the flanges are arranged at the two ends of the roll body, the dough band does not leak out in the dough mixing process and is even in width. Meanwhile, the grey cast iron roll body is wear-resistant, while the cold hard alloy roll body is squeezing-resistant, and therefore, the service life of the roll is greatly increased.

Description

A kind of composite roll

Technical field

The utility model relates to the roll technology field in pressure processing, specifically a kind of composite roll.

Background technology

Tradition is for the roll of Flour product processing preorder production line and face, and roll surface is smooth roll roll surface, and when face only by the gap between upper and lower roll surface, opposite band rolls, and often wear and leak outside, and width is inhomogeneous.Meanwhile, existing and face roll is solid forging or casting, in the time that roll uses body of roll position diameter and is less than standard size 10% left and right, reaches normal abandonment size, and now, roll is scrapped entirety, thereby has caused a large amount of wastes; And monoblock type roll can not meet high rigidity and the high-intensity requirement of roll entirety of roll working lining simultaneously.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of composite roll, to realize the object of raising and face quality and roll working life.

For achieving the above object, the utility model comprises spindle nose one, spindle nose two and the roll body that adopts bimetal centrifugal cast, and described roll body is at grey cast-iron roller extracorporeal set alloy cast iron roll body.

Described roll body two ends are provided with and make to wear the flange not leaking outside.

The utility model compared with prior art, be mainly used in Flour product processing with face operation, because roll body two ends are provided with flange, and wear when face and do not leak outside, width is even.Meanwhile, grey cast-iron roll body hardness and compression strength are high, alloy cast iron roll body good toughness, and resistance to extruding, acid and alkali-resistance, hardness and anti-wear performance are high, and is greatly improved the service life of roll.

Accompanying drawing explanation

Fig. 1 is structure diagram of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model comprises spindle nose 1, spindle nose 23 and roll body, and spindle nose 1, spindle nose 23 adopt 45# steel to make, and do modifier treatment, spindle nose 1, spindle nose 23 are respectively used to running in bearings and belt pulley, are mainly used in connecting roll body, and drive roll body to rotate; Roll body is at the outer suit alloy cast iron of grey cast-iron roll body 2 roll body 4, internal layer grey cast-iron roll body 2 is grey cast-iron HT200, hardness and compression strength are high, and outer layer alloys cast iron roll body 4 good toughness, resistance to extruding, acid and alkali-resistance, hardness and anti-wear performance are high, roll body is that bimetal centrifugal cast forms, and this combination can improve the Comprehensive service life of roll greatly; Roll body two ends are provided with flange 5, can effectively guarantee to wear not leak outside, and width is even.

Claims (1)

1. a composite roll, is characterized in that: comprise spindle nose one (1), spindle nose two (3) and the roll body that adopts bimetal centrifugal cast, described roll body is suit alloy cast iron roll body (4) outside grey cast-iron roll body (2); Described roll body two ends are provided with and make to wear the flange (5) not leaking outside.
