Abstract

The utility model relates to a three-roller flour mill, which belongs to grain processing equipment. The utility model is composed of three grinding rollers, wherein one grinding roller is a fast roller, and the other grinding rollers are slow roller; the fast roller and one slow roller are arranged at the upper part of the utility model; the other slow roller is arranged at the lower part of the utility model in an oblique mode; a corresponding synchronous rolling distance regulating mechanism are matched with the three rollers. The three-roller flour mill realizes the new flour milling technology of twice grinding and once sifting, and the grinding effect is obviously reinforced. Compared with the roller type flour mill, the utility model has the advantages that the production efficiency increases more than 50 per cent, the cost only increases less than 20 per cent, and the output and the quality are uniformly and obviously increased. The utility model is a generation product which can replace the roller type flour mill.

Description

Three roller flour mill

The utility model belongs to grain processing equipment, relates in particular to a kind of flour mill.

In the flour mill field, the pair roller type flour mill is modern flour industry and the widely used cereal disintegrating apparatus of food industry, its groundwork principle is a pair of different rotating speeds, (one of them is fast roller to Xuan Zhuan cylindrical grinding roller in opposite directions, another is slow roller, the speed ratio of speed roller is adjusted by the gear box of tricks), axis is parallel, roll surface is tangent, and wheat or other cereal are sent into screen mechanism Flour grading after grinding between two rollers, whole pulverizing process is the repeatedly repetition of grinding and screen, because adopt a pair of grinding roller, flouring technology can only be once to grind, a screen.In order to improve flour output and quality, the flour mill designer writes an article on grinding roller diameter and grinding roller length always, the long 1250mm that now developed into of roller, and roller footpath 320mm continues to add the big roller footpath and increases the long restriction that has been subjected to making mutual skill and cost of roller.

The application's purpose is to provide a kind of can realize twice grinding and lower-cost three roller flour mill.

For achieving the above object, the utility model adopts following technical scheme: on the basis of existing pair roller flour mill, increase a grinding roller (slow roller), this grinding roller is positioned at the below of pair roller, is connected with fast roller by gear differential structure.Pair roller can be horizontally disposed with, and also slow roller becomes 0 °～45 ° angles with fast roller horizontal line, and corresponding with it tilting following grinding roller becomes 70 °～20 ° angles with fast roller horizontal line.

In order to regulate three roll clearances between the grinding roller, except that the guiding mechanism of original pair roller flour mill, also be provided with the synchronous roll clearance adjusting mechanism of a cover, it is by handwheel, and leading screw, rocking arm and shared eccentric shaft are formed, in order to regulate the roll clearance between two slow rollers and fast roller simultaneously.

The utility model three roller flour mill has structurally increased a slow roller, plants mutually thereby changed traditional powder process, and by once grinding, a screen has become twice grinding, a screen; When material after grinding once between last slow roller and the fast roller, enter down at once between slow roller and the fast roller and carry out the grinding second time, send into screen mechanism then, fast roller drives slow up and down roller simultaneously by material, because the effect of gear box of tricks, it is poor that slow up and down roller and fast roller produce different speed, thereby make material realize continuously grinding twice, and roller has become shared fast roller soon here.Twice grinding makes grinding effect obviously strengthen, and compares with the pair roller flour mill, and production efficiency improves more than 50%, and cost only increases less than 20%, and output and quality are significantly increased.Usually wheat needs circulation 5-6 time on the pair roller flour mill, and only needs three times on three roller flour mill.

Below in conjunction with the embodiment accompanying drawing the application is described in further detail.

Fig. 1 is the transmission principle schematic diagram of three roller flour mill.

Fig. 2 is the side-looking structural representation of three roller flour mill.

Fig. 3 is another embodiment side-looking structural representation of three roller flour mill.

Among Fig. 1, the 1st, feeding roller, the 2nd, last slow roller, the 3rd, fast roller, the 4th, following slow roller.Grind when doing mutually, motor 6 drives fast roller 3 by belt 7 and rotates, because the effect of gear box of tricks 8, upper and lower slow roller 2,4 produces different speed ratios with fast roller 3, material after process is ground for the first time between last slow roller 2 and the fast roller 3, enters down between slow roller 4 and the fast roller 3 and carries out the grinding second time under certain pressure at once, enter rotary strainer 5 Flour gradings then, enter three roller flour mill after oversize is raised once more and carry out next one grinding circulation.

Fig. 2 shows the lateral location relation of three grinding rollers, the axle 10 of fast roller 3 is horizontal with the axle 11 of last slow roller 2, and axis is parallel, and the axle 13 of following slow roller 4 is positioned at the below of above-mentioned diaxon, the single line arrow shows the rotation direction of three rollers among the figure, and double-lined arrow shows the direction of motion of material.In order to regulate the roll clearance between slow roller and fast roller, this three roller flour mill has designed unique synchronous roll clearance adjusting mechanism at the casing opposite side, form by handwheel 15, leading screw 16, rocking arm 17, shared eccentric shaft 18, handwheel 15 connects leading screw 16, and be supported on the casing 9, the other end of leading screw 16 and rocking arm 17 flexibly connect, shared eccentric shaft 18 is between two slow rollers, and in casing, fixedly connected slow roll bearing seat 12, following slow roll bearing seat 14 and the rocking arm 17 of its end, the also fixedly connected bearing block of slow roller up and down of the other end.Here go up slow roller 2, fast roller 3 is equivalent to slow roller and fast roller in the pair roller flour mill, the following grinding roller of following slow roller 4 for setting up in the three roller flour mill, corresponding therewith, upper and lower slow roll bearing seat is slow roll bearing seat and following grinding roller bearing block.Rotate handwheel 15, drive leading screw 16 motions, when leading screw advanced from left to right, it was simultaneously close to fast roller to drive slow up and down roller; When the leading screw right-to-left retreated, slow up and down roller then left fast roller simultaneously, realizes the adjusted in concert of roll clearance between grinding roller with this.

For realizing down the normal feeding of slow roller, three roller flour mill adopts that to go up slow roller horizontal with fast roller, and the tilting and rotating speed of following slow roller is higher than slow roller, need not increase the purpose that drawing-in device just can be realized two subnormal grindings thereby reach.

Fig. 3 is another embodiment of three roller flour mill, slow roller becomes 0 °～45 ° angle settings with fast roller horizontal line in the employing, tilting and the fast roller horizontal line of the slow roller that matches down with it becomes 70 °～20 ° angles, adopt roughly the same box of tricks and roll clearance adjusting mechanism synchronously, can realize that equally a shared fast roller reaches the purpose of twice grinding of material.
