Description
Technical field
The present invention relates to the paddy hulling rubber roll in rice milling unit, namely one exempts from replace wheeled serial paddy hulling rubber roll and production method thereof, this rubber roll in use need not replace can single use complete, can be applicable in the existing whole wheeled rubber roll huskers manufactured both at home and abroad.
Background technology
Paddy hulling rubber roll is the core component of hulling machine, is mainly used in paddy husking, easily wears away, and consumption is large.Paddy hulling rubber roll is divided into wheeled series and shell type series two classes by installation way, amounts to tens kinds of specifications and models.Wheeled series is with base core (iron or aluminium) inboard wall flange plane (axis) and Flange Plane endoporus (radial direction) location, and with the paddy hulling rubber roll of the fastening multiple appearance and sizes of nut, as shown in Figures 1 and 2, rubber layer 1 is surrounded by the outside of iron core 2, there are locating hole 5 and plane of orientation 4 in the inside of iron core 2, and the periphery of locating hole 5 has been evenly arranged four fastening bolt holes 3.
Rubber roll is the core work component of hulling machine, is a pair equal diameter and whippy rubber roller, and two roll axis are positioned at same level or slightly difference in height, and with different rotating speeds opposite direction rotating, what linear speed was high is fast roller, and what linear speed was low is slow roller.Paddy feeds between two rollers in rubber roll total length equably with certain flow velocity, after being subject to two roller extruding, producing stranding and tears effect, thus paddy is peeled off as brown rice by two roller linear speed differences.Therefore, linear speed difference between speed roller produces to rub with the hands to tear the prerequisite of effect, directly affect shelling ability and rubber abrasion, is also that (linear speed difference is little for decision paddy flow velocity (flow velocity is greatly that production capacity is large) and roll gap pressure, husking yield decline, can improve roll gap pressure improve) key element.The linear speed difference of hulling machine is according to paddy husking rate and production capacity design, therefore, uses, be conducive to the efficiency and the production capacity that improve paddy husking, reduce glue consumption and equipment failure rate in rational hulling machine linear speed difference scope.
Linear speed, the linear speed difference of rubber roll are introduced: the linear speed of rubber roll means rubber roll peripheral speed operationally, that is:
V=πDN/60(m/s)
In formula: D-top roller diameter (m)
N-rubber roll rotating speed (r/min)
Linear speed difference refers to the difference of the linear speed of fast roller and slow roller, that is:
VA=V1-V2
In formula: the linear speed difference (m/s) of VA-rubber roll
V1-fast roller linear speed (m/s)
V2-slow roller linear speed (m/s)
Domestic and international hulling machine can be divided into three kinds of types by the linear speed difference scope of application: 1, linear speed difference is at 3.4-4m/s, and this is equipment comparatively advanced at present; 2, linear speed difference is at 2.6-3.2m/s, and this is universal equipment; 3, the hulling machine of 2.6-3.2m/s is less than.Existing hulling machine adopts single belt (flat belt, hexagonal belt, Timing Belt) transmission mostly, the rotating speed of two rollers is constant, but because the quality of rubber materials of two rubber rolls is identical, causing the abrasion of speed roller, inconsistent (abrasion of fast roller are large, slow roller abrasion are little), its linear speed along with the abrasion of rubber roll but gradually consistent, tear stranding effect and weaken gradually, cause husking yield obviously to decline.In order to avoid this disadvantage, equipment operating requires that, when two roller footpath difference 5mm, need shut down and be exchanged by speed roller, linear speed is poor to regain comparatively reasonably.As requested, a pair new rubber roll is finished using from installing to, palpus roll change 7-8 time.During roll change, shutdown, loading and unloading clamp about need about 30 minutes used time, and every pair roller barrel calculates, by about 210 minutes consuming time for 7 times by roll change.Separate unit hulling machine is produced also better, if the parallel operation of multiple stage hulling machine works, by 4 hulling machine parallel operation, once, light roll changing time must 120 minutes in per tour roll change.Not only the labour intensity of operative employee is large, and the economic benefit of husk rice enterprise is also greatly affected.Therefore, in actual use, operative employee is in order to save time; reduce roll change number of times; reduce labour intensity, when mostly adopting fast roller to wear away 1/2, just shut down exchange, or simply wait until that changing the new rubber roll of another after fast roller wears away uses with slow roller before simultaneously.There is shortcomings in this violation operation: 1, linear speed difference reduces, and husking yield declines; 2, in order to improve husking yield, operative employee can keep husking yield to improve roll gap pressure (strong tight roller), and this will cause glue consumption, energy consumption and fault rate to increase; 3, linear speed difference is less than paddy flow, and paddy is piled up at roll surfaces, produces local flow uneven, causes glue face to destroy (grooving, local are come unstuck); If 4 only change a new rubber roll, two roller linear speed differences will be made excessive, cause vibration equipment large, rubber roll temperature rise, roll surface destructible, yielding, the invalid wearing and tearing of rubber are many; 4, linear speed difference is too small or cross big city's impact rice huller paddy effect, and cause broken rice rate high, steaming again paddy increases, and also affects the result of use of paddy hulling rubber roll simultaneously.
Summary of the invention
The object of the invention is by raw-materially choosing polyurethane rubber and butadiene hydrocarbon rubbers etc., the setting up and the various combination of rubber compounding of technical indicator, manufacture fast roller and slow roller respectively, reach that the abrasion of speed roller glue face are basically identical and to exempt transposition tired.
Thisly exempt from the wheeled serial paddy hulling rubber roll that replaces, it is characterized in that, comprise a fast roller and a slow roller, the external diameter difference of slow roller and fast roller is 0-5mm, the formula of their surface parcel rubber is different, in work, the performance of abrasion performance is different, but they are isopyknic abrasion in the work of different revolution, and the linear speed of fast roller and slow roller difference is remained in an optimum scope.
The abrasion of rubber are the process of a mechanical damage in essence.Its is main with the molecular structure of main gel, various physical and mechanical properties of vulcanizate, mainly relevant with breaking strength, elongation at break, hardness factor, while also, paddy seed-grain as poor in temperature, linear speed with the service condition of rubber because have substantial connection.Its influence factor is a lot, and according to rubber abrasion mechanism in the past, the abrasion of rubber are mainly divided into two kinds of forms: 1, abrasion wear, 2, tired abrasion; As follows with regard to these two kinds of forms application note in the present invention below:
One, paddy hulling rubber roll rubber layer because of hardness high, Shao Er hardness 90A-95A, intensity is large, relative deformation is little, constantly cut by sharp-pointed, coarse grain, swipe under duty, pull apart into small particle, therefore, the abrasion of rubber are auxiliary process based on the abrasion of the fatigue of the shearing behavior of abrasion wear, relaxed stress; So utilize Akron abrasion value and rubber volume rate of wear to weigh, determine paddy hulling rubber roll rubber abrasion advantageously:
The result of Akron abrasion experiment, can be expressed as the wear volume in the mileage of 1.61km, that is:
U=(g2-g1)/P(formula 1)
In formula: U-wear volume (cm3)
P-sample density (g/cm3)
G1, g2-be respectively the quality testing front and back sample
Two, the result of volume worn rate is expressed as contact one timing, and the rubber volume rate of wear of unit distance is directly proportional to the long-pending inverse of the hardness of sample, breaking strength, elongation at break three, namely
A=K/HQ ε (formula 2)
In formula: A-volume worn rate,
K-constant, generally gets 1
H-sample hardness
Q-sample breaking strength
ε-sample elongation at break
Rubber abrasion volume ratio under fast, the slow roll working state of existing paddy hulling rubber roll, through repeatedly on-the-spot test, result is:
During linear speed difference 2.6-3.2m/s, fast roll body amasss (B is fast): long-pending (B the is slow)=100:60 of slow roll body;
During linear speed difference 3.4-4m/s, fast roll body amasss (B is fast): long-pending (B the is slow)=94:60 of slow roll body;
Three, the relation between U, A, B three: wherein A is empirical value during we work, reflects the relation between volume worn rate A and rubber physical mechanical property, and A value is less, and wearability is better; According to the test data provided in GB GB/T1689-1998, Akron abrasion value U can be used to the wearability weighing main gel, can check, verify the reliability of volume worn rate A, slowly, the wear volume of fast roller must solve the synchronous wearing and tearing of paddy hulling rubber roll by volume worn rate A and Akron abrasion value U than B, meet following formula, fast roller wear volume=slow roller wear volume can be solved:
U is fast: U is slow=A is fast: and A is slow=and B is slow: B fast (formula 3)
In formula: U is fast, U is slow---the Akron abrasion value of fast, slow roller;
A is fast, A is slow---the volume worn rate of fast, slow roller;
B is slow/and B is fast---the wear volume ratio of slow, fast roller.
Rubber roll outside dimension can be adjusted change within the scope of 0-5mm, the abrasion difference caused with the hulling machine reducing various different linear speed difference scope.
Advantage of the present invention
1, optimize linear speed difference scope, be conducive to improving production capacity, give full play to the service efficiency of rubber roll;
2, the invalid abrasion of rubber reduce, and can extend the service life of rubber roll;
3, the high and low all kinds of negative effects caused of linear speed difference are avoided;
4, save roll changing time, reduce labor strength;
5, be conducive to multiple stage hulling machine parallel operation operation, adapt to large-scale continuous production.

Foregoing invention is set about from the wear characteristic of rubber, utilizes multiple technologies means fundamentally to solve the synchronous abrasion of speed roller.But paddy hulling rubber roll is under actual working state, also can be subject to paddy seed-grain (husk thickness, soft or hard), environment temperature (Summer and winter and different regions) and the abrasion difference of different linear speed difference caused by hulling machine, be in particular in following three aspects:
For the hulling machine of linear speed difference 3.4-4m/s, speed roller wear volume compares 94:60, because linear speed difference is large, frictional heat, rubber roll temperature is slightly high, fast roller rubber abrasion is bigger, therefore increases fast roller outside dimension 0-5mm(and is equivalent to improve rubber abrasion volume 0-13%) be conducive to improving the operating efficiency of paddy hulling rubber roll, increase the service life.
Linear speed difference is less than to the hulling machine of 2.6-3.2m/s, reduces fast roller 0-5mm, can ensure that paddy hulling rubber roll synchronously wears away, and linear speed difference scope all-the-time stable.
When paddy hulling rubber roll is thick in rice hulls, hard and summer, height is when thermally district uses, is reasonable to reduce slow roller 0-5mm.
In sum, adjustment rubber roll outside dimension changes within the scope of 0-5mm, pointed, is of the present invention supplementary and perfect.
