Abstract

The utility model provides a combined hollow roller for crushing a dough. The combined hollow roller for crushing the dough is mainly applied to the dough crushing step in flour product processing. The combined hollow roller comprises a shaft with a shaft head I and a shaft head II, and a roller body centrifugally cast from two metals, wherein the roller body is formed by sleeving an alloy cast iron roller to a grey cast iron roller body; a hole is formed in the center of the roller, a plug I and a plug II are mounted in holes formed in the two ends of the roller, respectively, the shaft head I is connected with the plug I through a key, the shaft head II is connected with the plug II by virtue of interference fit, the surface of the alloy cast iron roller body is a cross-grain structure, and the cross-grain structure is provided with a cutting blade. The combined hollow roller for crushing the dough is mainly applied to the dough crushing step in the flour product processing; as the cross grains are formed on the surface of the roller, the rolling force is enlarged and the dough crushing effect is good; the roller is a through shaft, the form and location tolerance between the shaft and the roller can be guaranteed in the processing course, and when in use, shaft breakage and shaft drift can be avoided, and the service life of the roller can be effectively increased; meanwhile, as the roller body is a large hollow structure, the weight of the roller is reduced, and for operation, a low-power motor can be chosen to drive the roller, and therefore, the energy source is saved.

Description

A kind of plane of disruption combined hollow roll

Technical field

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

Background technology

Tradition for make face fragmentation roll, there is following defect:

1, roll surface is smooth roll roll surface, and when the plane of disruption, only by the gap between upper and lower roll surface, opposite band rolls, but the crushing effect of face is poor.

2, existing plane of disruption 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 plane of disruption combined hollow roll, to realize the quality and the roll working life that improve the plane of disruption, and reduces the object of energy consumption.

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 twill structure.

Described twill structure is with blade.

The utility model compared with prior art, is mainly used in the plane of disruption operation of Flour product processing, and because roll surface has twill, calendering puts more effort, the plane of disruption effective.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 twill structure, and with blade 5, makes to roll putting more effort of face, the plane of disruption effective.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.
