Description

Compound six roller flour mill transmission mechanisms

The utility model relates to the flour mill transmission mechanism, belongs to the flour mill technical field.

The compound eight-roller mill of existing grain processing; form four working cells by four groups of speed rollers, each group speed roller is joined a cover transmission system and a motor, four groups of speed roller configuration quadruplet transmission systems and four motors; the transmission system bulky complex; the cost of manufacture height, the power consumption height is easy in the use be out of order: in addition; regulating wheel only can be done rectilinear motion in the transmission system; scope of activities is little, when the grinding roller roll clearance changes greatly, can't realize reliable safeguard protection effect.The compound triple-roller mill roller machine of development in recent years, a fast roller adds two slow rollers and can form two working cells, compound six roller flour mills are equivalent to the operating efficiency of existing eight-roller mill, the transmission mechanism of above-mentioned eight-roller mill is backward relatively, should develop simple and practical, the transmission mechanism that suitable compound six roller flour mills use.

The purpose of this utility model be to provide a kind of simple in structure, use reliable, low cost of manufacture, the transmission mechanism that suitable compound six roller flour mills use.

The purpose of this utility model is achieved in that

A kind of compound six roller flour mill transmission mechanisms, it comprises two separate transmission unit 18 of left and right symmetry, each gear unit comprises

drive sprocket

1,2,3, tightener sprocket 4,5, chain 6 and regulating and controlling mechanism 7, drive sprocket 1 be with fast roller is coaxial is connected, drive

sprocket

2,3 respectively with upper and lower coaxial connection of slow roller, chain pile warp drive sprocket 1, regulating wheel 4,5 form closed loop, and two outer side edges of closed loop are in transmission connection with

drive sprocket

2,3 respectively.

Above-mentioned compound six roller flour mill transmission mechanisms, described regulating and controlling mechanism 7 comprises swing arm 8, adjusting rod 9, spring 10, swing arm one end and flour mill are hinged, the hole 11 of its other end is set in the adjusting rod lower end with big gap, the upper end of adjusting rod is connected with flour mill, spring is positioned at the upper surface in hole 11, and one of described two regulating wheels are installed in the swing arm.

Above-mentioned compound six roller flour mill transmission mechanisms, described hole 11 is the open slot of a U-shaped.

Above-mentioned compound six roller flour mill transmission mechanisms, the upper and lower end face in described hole 11 is set up upper and

lower pressure pad

12,13, for knife-edge contacts, contacts for the cambered surface line between following pressure pad and the lower surface between last pressure pad and the upper surface.

Above-mentioned compound six roller flour mill transmission mechanisms, described adjusting rod upper end is fixed on the flour mill support 14 by two ball rings 16 and nut.

The utility model is easy, practical; Regulating and controlling mechanism in the transmission mechanism can prevent effectively that roll clearance is unexpected when changing to impact, the destruction of transmission mechanism, it is low to adopt flour mill of the present utility model to have cost of manufacture, fault rate is low, parts are not fragile, security is good, use advantages such as reliable, suit on compound six roller flour mills, to adopt.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation;

Fig. 2 gear unit enlarged drawing:

Fig. 3 is a regulating wheel regulating and controlling mechanism structural representation;

Fig. 4 is the left view of Fig. 3.

Consult Fig. 1,2, among the figure, 17 is bodies of six roller flour mills, a left side in the body, two groups of grinding rollers of right symmetrical placement, every group of grinding roller is by last, slow roller and middle fast roller are formed down, 18 is two separate transmission unit, each gear unit is by a motor-driven, drive sprocket 1 in each gear unit is installed on the axle head of the fast roll shaft in every group of grinding roller, another axle head of fast roller is in transmission connection by big belt pulley 20 and motor 19, drive

sprocket

2,3 are installed in respectively, down on the axle head of slow roller, regulating wheel 4 is installed on the flour mill body, tightener sprocket 5 is installed on the regulating and controlling mechanism 7, chain 6 pile warp drive sprockets 1, regulating wheel 4,5 form closed loop, closed loop two the ring limits the outside respectively with

drive sprocket

2,3 are in transmission connection, drive sprocket 1 and drive

sprocket

2,3 diameter is than being speed roller speed ratio, by the rate of tension of the adjustable pitch chain bar of regulating and controlling mechanism.

Consult Fig. 3,4; in the illustrated regulating and controlling mechanism 7; one end and the flour mill of swing arm 8 are hinged; the other end is provided with hole 11, and this Kong Yida gap is sleeved on the lower end of adjusting rod 9, and the adjusting rod upper end compresses with support by nut by two ball rings 16 and is connected; support 14 is fixed on the flour mill; spherical nut can alleviate the frictional resistance when regulating adjusting rod, when also allowing adjusting rod stressed certain swing is arranged, and adjusting device is had protective effect.Upper and

lower pressure pad

12,13 is sleeved on the adjusting rod 9, last pressure pad 12 contacts with the knife-edge of 11 upper surfaces, hole: go up the edge of a knife of establishing projection on the pressure pad 12, the upper surface in hole 11 is provided with recessed cutter groove, the edge of a knife is arranged in the cutter groove, and the opening angle of cutter groove is greater than edge of a knife angle: following pressure pad 13 is designed to arc surface with the lower surface in hole 11, and the arc radius of 11 lower surfaces, hole is less than the arc radius of pressure pad 13 down, like this, the contact of the two is the linear contact of circumference, and when hole 11 was U-lag, contact was two lines.Spring 10 is a butterfly spring, is pressed on the pressure pad by nut 15.In the grinding roller work, the accident that roll clearance often occurs changes, as snapping in larger particles between grinding roller suddenly, at this moment, on, slow roller forces chain to shrink down, tightener sprocket 5 drives upwards swing of swing arm 8, owing to have big gap between hole 11 and the adjusting rod 9, and on the hole 11, lower surface and last, following

pressure pad

12,13 is that cutter contacts with line, so allow swing arm relative adjustment bar to have certain corner, can move in or out when regulating wheel 5 is moved up and down, so just enlarge the adjusting free degree of regulating wheel, make regulating wheel can adapt to the contraction of chain to required direction motion, so can guarantee the operation work of transmission system safety and steady ground, when reducing roll clearance and changing to the impact of transmission system, thereby reduce the damage of flour mill parts, improved the dependability of flour mill.
