CN203648988U - Corrugation combined type roller - Google Patents

Abstract

The utility model discloses a corrugation combined type roller which is mainly applied to the dough kneading process in flour product processing. The corrugation combined type roller comprises a first shaft head, a second shaft head and a roller body which is formed by duplex metal in a centrifugal pressure casting mode. According to the roller body, a grey cast iron roller body is sleeved with an alloy cast iron roller body, and the surface of the alloy cast iron roller body is of a corrugated structure. Flanges which enable a dough strap to be not leaked outside are arranged at the two ends of the roller body. According to the corrugation combined type roller, due to the fact that corrugations are arranged on the roller face, the rolling area is increased, the rolling dough strap is lengthened, wheat gluten is good in pulling toughness and mouthfeel after being pressed, the wheat gluten cannot be broken easily, the dough strap cannot be leaked outside, and the width is even. Meanwhile, the grey cast iron roller body is high in hardness and compressive strength, the alloy cast iron roller body is good in toughness, extrusion resistant, acid and alkali resistant and high in hardness and abrasion resistance, and thus the service life of the roller is greatly prolonged.

Description

Corrugated combined type roll

Technical field

The utility model relates to the roll technology field in pressure processing, specifically a kind of corrugated combined type 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, but because calendering dynamics and calendering area do not increase, gluten is easily broken.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 corrugated combined type 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.

The surface of described alloy cast iron roll body is ripple struction.

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 surface has ripple, calendering area strengthens, lengthening is worn in calendering, muscle is dragged after combined pressure, toughness and mouthfeel are good, should not break, and wear 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.

Brief description of the drawings

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

Detailed description of the invention

As shown in Figure 1, the utility model comprises spindle nose 1, spindle nose 22 and roll body, and spindle nose 1, spindle nose 22 adopt 45# steel to make, and do modifier treatment, spindle nose 1, spindle nose 22 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 3 roll body 4, internal layer grey cast-iron roll body 3 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; The surface of alloy cast iron roll body 4 is ripple struction, makes to roll area and strengthens, and lengthening is worn in calendering, and muscle is dragged after combined pressure, and toughness and mouthfeel are good, should not break; Roll body two ends are provided with flange 5, can effectively ensure to wear not leak outside, and width is even.

Claims (3)

1. a corrugated combined type roll, is characterized in that: comprise spindle nose one (1), spindle nose two (2) 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 (3).

2. corrugated combined type roll according to claim 1, is characterized in that: the surface of described alloy cast iron roll body (4) is ripple struction.
