Abstract

The utility model discloses a corrugated combined type hollow roller which is mainly applied to flour product processing and four kneading working procedures. The corrugated combined type hollow roller comprises a roller body which is formed by double-metal centrifugal casting, wherein the roller body is formed by sleeving a grey cast iron roller body with an alloy cast iron roller body; a hole is formed in the center of the roller body; a plug I and a plug II are respectively arranged in holes in two ends of the roller body; a spindle head I is connected with the plug I by virtue of a key; a spindle head II is in transitional fit with the plug II; a corrugated structure is arranged on the surface of the alloy cast iron roller body; flanges for preventing flour bands from being leaked are arranged at two ends of the roller body. The roller surface of the roller disclosed by the utility model is corrugated, so that the rolling area is enlarged, and the rolling flour band is lengthened; due to rolling, glutens are high in dragging resistance and toughness and good in taste and are difficult to break; the flour bands cannot be leaked, and the width is uniform; the roller adopts a through shaft, so that the form and location tolerance of the shaft and the roller body can be guaranteed in a working process; during use, shaft breakage and shaft stringing can be avoided, and the service life of the roller is effectively prolonged; meanwhile, the roller body is of a large hollow structure, so that the weight of the roller body is reduced; the roller can be driven by a low-power motor during running, so that energy can be saved.

Description

Corrugated combined type hollow roll

Technical field

The utility model relates to the roll technology field in pressure processing, specifically a kind of corrugated combined type hollow roll.

Background technology

For the roll of Flour product processing preorder production line and face, there is following defect in tradition:

1, 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.

2, 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.

3, the assembling of traditional roll and axle adopts the mode of colding pressing, and by the first chamfering in the two ends of axle, axle is knocked in roll with iron hammer, then axial compression is entered to roll with forcing press.This mode, requires quite highly to the mating surface of axle and roll, and easily occur string axle, the phenomenon such as burst, and because of being cold-pressing assembly, and after installation use a period of time, the defects such as jerk value is excessive easily appear in roll.

4, roll body Heavy Weight, when operation, power of motor is large, and energy consumption is high.

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 hollow roll, improves and face quality and roll working life, and reduce the object of energy consumption to realize.

For achieving the above object, the utility model comprises the axle and the roll body that adopts bimetal centrifugal cast with spindle nose one, spindle nose two, and described roll body is at grey cast-iron roller extracorporeal set alloy cast iron roll body; The center of roll body is porose, and plug one is respectively charged in the hole at roll body two ends with plug two, and spindle nose one is connected by key with plug one, and spindle nose two is connected by interference fit with plug two.

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.And what the roll of this structure adopted is axis, can guarantee the form and position tolerance of axle and roll body in process, when use, axle is stressed evenly, avoid off-axis and altered axle, meanwhile, because roll body is large hollow-core construction, alleviate roll body weight, when operation, can select low-power machine to drive, saved the energy.

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 axle and the roll body with spindle nose 1, spindle nose 22, 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, be 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 guarantee to wear not leak outside, and width is even.The center of roll body is large hollow-core construction, plug 1 packs in the hole at roll body two ends by interference fit respectively with plug 27, spindle nose 1 is connected by key 8 with plug 1, spindle nose 22 is crossed and is connected by interference with plug 27, because roll body is large hollow-core construction, greatly alleviate roll body weight, when operation, can select low-power machine to drive roll body motion, saved the energy.

Claims (2)
