Grinder 1 includes crocus mechanism 102 to and set up discharge mechanism 103 of crocus mechanism 102 one side, discharge mechanism 103's discharge gate is located the initiating terminal top of refining output mechanism 101.

As shown in fig. 9, the discharging mechanism 103 includes a flat outlet discharging pipe 1031, the flat outlet discharging pipe 1031 is located above the starting end of the refining output mechanism 101, a plurality of flow blocking strips 1032 for conducting multiple diversion and diversion on flour in order to promote the gradual flattening of the flour in the outflow process are installed in the end of the discharging direction of the flat outlet discharging pipe 1031, the flow blocking strips 1032 are uniformly distributed on both sides of the discharging direction of the flat outlet discharging pipe 1031, and the end of the discharging direction of the flow blocking strips 1032 on both sides is inclined towards the side wall direction of the flat outlet discharging pipe 1031 on the same side.

Flour conveyed by the flour grinding mechanism 102 is concentrated and uneven in thickness, and when the flour passes through the flat outlet pipe 1031, the plurality of flow blocking strips 1032 on the bottom pipe wall of the flat outlet pipe 1031 have the effect of guiding the flour to two sides, so that the flour is gradually spread in the directions of two sides through the gradual shunting and drainage of the plurality of flow blocking strips 1032, and the flour is quickly shaken flat by the refining output mechanism 101.

It is further optimized in the above embodiment that the flow guide grooves 1033 are formed in the front wall of the flat outlet pipe 1031 opposite to the flow blocking strips 1032, the groove walls of the flow guide grooves 1033 facing the ends of the flow blocking strips 1032 are in transitional connection with the inner wall of the flat outlet pipe 1031, and the flow blocking strips 1032 on both sides are symmetrically arranged with respect to the flow guide grooves 1033.

The flour is uniformly guided and divided by the plurality of flow blocking strips 1032 on the two sides by the flow guide grooves 1033, so that the adverse effect on the spreading uniformity of the flour due to the large difference of the flour amount flowing to the flow blocking strips 1032 on the two sides is avoided.

As shown in fig. 1, 4 and 8, the refining output mechanism 101 includes a supporting base 13 obliquely installed on the integrated processing platform, a flat outlet pipe 1031 is located above one end of the supporting base 13 which is tilted upward, a refining trough plate 1011 located below the flat outlet pipe 1031 is arranged on the supporting base 13, the refining trough plate 1011 is installed on the supporting base 13 through a shaker 1012, and the shaker 1012 drives the refining trough plate 1011 to shake so as to flatten flour in the refining trough plate 1011.

The refining trough plate 1011 is shaken continuously by the shaker 1012, and the flour piled on the refining trough plate 1011 is dispersed and extends to the inner walls of the two sides of the refining trough plate 1011 in the continuous shaking process, so that the flour on the refining trough plate 1011 is gradually spread into flour belts with uniform thickness.

While the shaker 1012 is a drive for shaking the sieve or other equivalent functional component, it is common practice to level the top of the granules or powder in the container by shaking the container.

It should be noted that the inclination angle of the refining trough plate 1011 relative to the horizontal plane is 2-5 °, so as to avoid that the flour moves onto the stacking conveyor belt 302 before spreading on the refining trough plate 1011 due to an excessively large inclination angle of the refining trough plate 1011.

The refining trough plate 1011 is fitted with a vibrator 1013 toward the bottom of the support base 13, and the vibrator 1013 drives the refining trough plate 1011 to vibrate after the shaker 1012 is stopped and reset to promote further flattening of the flour to form a flour strip.

The integrated processing platform 301 is further provided with an inclined material conveying plate 15 located between the refining trough plate 1011 and the stacking conveyer belt 302, the front end of the inclined material conveying plate 15 facing the refining trough plate 1011 is located below the refining trough plate 1011, and the tail end of the refining trough plate 1011 relative to the refining trough plate 1011 is located above the stacking conveyer belt 302.

The inclined material conveying plate 15 is used for promoting the flour belt to be continuously conveyed to the stacking conveying belt 302, the inclined angle of the inclined material conveying plate 15 is larger than that of the material homogenizing groove plate 1011, interruption of the flour belt in the conveying process of the stacking conveying belt 302 by means of self gravity due to the fact that the inclined angle of the material homogenizing groove plate 1011 is smaller is avoided, and the fact that the thickness of the flour belt is uniform and consistent at all positions in the conveying process is guaranteed.

As shown in fig. 1, 4 and 5, the inclined material conveying plate 15 is provided with rotary supports 20 on both sides, the rotary supports 20 on both sides are connected by a driving shaft, the driving shaft is parallel to the inclined material conveying plate 15, a rough roller 21 is coaxially arranged on the driving shaft, the rough roller 21 is provided with a plurality of material dividing cavities for quantitatively dividing the flour belt, the flour belt conveyed by the inclined material conveying plate 15 is divided into flour piles and conveyed by rotating the material dividing cavities along the surface of the inclined material conveying plate 15, and the inclined material conveying plate 15 is in an arc shape coaxial with the rough roller 21.

The multiple blanking cavities rotate along with the roughing rollers 21, after one end of the blanking cavity in the rotation direction is in contact with the arc-shaped inclined material conveying plates 15, a metering cavity with an open top and a gradually closed opening along with the rotation of the roughing rollers 21 is formed between the packaging enclosing plate and the inclined material conveying plates 15, when the metering cavity is closed, namely after two ends of the packaging enclosing plate are both connected with the inner sides of the inclined material conveying plates 15, one end of the metering cavity, relative to the rotation direction, is opened along with the rotation of the roughing rollers 21, so that flour in the metering cavity is conveyed under the pushing of the rotating blanking cavities, the purpose of pre-stacking the flour through the rotating multiple blanking cavities is achieved, and the segmentation of the fuzzy segmentation lines formed by pre-segmentation processing of a subsequent directional segmentation mechanism is facilitated.

Moreover, since the thickness of each part of the flour belt after the shaking treatment of the refining trough plate 1011 is uniform, the weight of the flour in the metering cavity is considered to be in direct proportion to the opening time of the front end opening of the metering cavity, and the opening time of the metering cavity opening can be adjusted by adjusting the rotating speed of the roughing roller 21, which is beneficial to improving the precision of quantitative segmentation of a subsequent quantitative segmentation mechanism.

As shown in fig. 4 and 5, the material intermingling cavity comprises an anti-overflow ring 14 and material intermingling strips 22, the anti-overflow rings 14 for accommodating flour overflow are mounted at both ends of the roughing roller 21, the material intermingling strips 22 which are uniformly distributed in the circumferential direction are mounted between the anti-overflow rings 14 at both ends, and a metering cavity for accommodating a flour stack is formed between the anti-overflow rings 14 at both ends and the adjacent material intermingling strips 22.

The function of the material spacing plate 22 is to divide the flour continuously output, and the opening and closing of the two ends of the metering cavity are realized along with the rotation of the rough roller 21 and the function of pushing the flour to the stacking conveying belt 302, and the function of the anti-overflow ring 14 is to prevent the flour from overflowing from the two ends of the metering cavity.

It is further explained that the width of the inclined material conveying plate 15 is not less than the distance between the two anti-overflow rings 14, so that the purpose that the outer ends of the metering cavity are sealed by the cooperation of the two anti-overflow rings 14 and the inclined material conveying plate 15 is achieved, and the distance between the two anti-overflow rings 14 is greater than the width of the outlet of the refining trough plate 1011, so that flour can be completely conveyed into the metering cavity through the refining trough plate 1011.

In order to ensure the smooth and accurate rotation of the roughing roller 21 and the smooth operation of the roughing roller 21 during the process of synchronously packaging a plurality of bags of flour, the roughing roller 21 is preferably set to rotate continuously at a constant speed, the pre-divided stacks of flour are continuously conveyed to the stacking conveyor belt 302 by adjacent metering cavities, and the width of the dividing line between the pre-divided stacks of flour conveyed to the stacking conveyor belt 302 is equal to or close to the thickness of the material dividing strips 22. Therefore, in order to ensure the pre-division effect and the strength of the material spacing strips 22, the thickness of the material spacing strips 22 is not too small.

However, since the refining trough plate 1011 continuously feeds the flour during a single supply for packaging a plurality of bags of the flour, and a part of the flour is accumulated between the outer side of the material spacing strip 22 and the inclined material feeding plate 15 in the process that the material spacing strip 22 is gradually contacted with the inclined material feeding plate 15 by the rotation of the roughing roller 21, the thickness of the material spacing strip 22 is not preferably too small to ensure the strength of the material spacing strip 22, which results in a small amount of flour on the dividing line between the pre-divided stacks of the flour, but even a small amount of flour may adversely affect the subsequent packaging process with the dividing line as the packaging boundary.
