Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flour mill, in particular to a flour mill. BACKGROUND

[0002] The flour mill (also known as flour milling machinery) is mainly used for processing wheat, corn and other grain crops, grinding them into powder, and then separating the flour and bran through sieving. The flour mill is the main equipment for milling wheat and corn and other coarse grains, and commonly used are roller type, cone type and disc type (steel mill) three kinds. Their working principles are all to use extrusion and grinding method to grind wheat into powder, and then use fine sieve to separate the flour and bran.

[0003] Among them, the disc type flour mill is evolved from traditional stone mill, using manpower or animal power as power or electric motor, through the parallel line type tooth slot plane of eight-zone and ten-zone inclined line type partition of two layers of the disc, the same tooth slot of the two layers, the reverse buckle rotation direction of the upper layer is opposite to that of the lower layer, and there are textures at the joint of the two layers. In the actual grinding process, through the parallel operation of the grinding disc, the lower disc is static and the upper disc is rolling when the stone mill works. The food material enters the middle of the two layers from the hole above and moves outward along the texture. The grinding and refining effect is realized when the material rolls through the friction of the two layers of surface.

[0004] However, the disc type flour mill has low working efficiency of 20-30 revolutions per minute in actual use, and the limitation of low speed and design texture leads to short single use life and unqualified grinding fineness. The two layers of grinding disc friction in the stone mill during grinding causes a large amount of stone powder generated by the wear of the main material, which cannot be separated from the refined material and directly ingested, leading to various types of stones and unpredictable carcinogenic diseases.

[0005] And the upper disc of the common disc type flour mill rotates, and under the action of gravity, the upper disc and the lower disc inevitably collide, thereby generating corresponding stone powder or iron powder. At the same time, the contact between the upper disc and the lower disc generates high temperature, which causes the nutrition and trace elements of the food material, and leads to the burning of the food material. The strong carcinogen benzopyrene in the burned food material can induce stomach cancer, lung cancer, laryngeal cancer, nasopharyngeal cancer, oral cancer, esophageal cancer and other unpredictable carcinogens. At the same time, the finished product needs to be exposed to wind cooling due to high temperature, which also causes secondary serious pollution of the finished product and serious exceedance of coliform bacteria.

[0006] Chinese patent number CN108160202A discloses a food grinder with adjustable grinding fineness, comprising a supporting leg, a lower grinding disc, an upper grinding disc, a hopper, a rotating module, a gap adjusting module, a cleaning module and a detection module, a circular truncated cone boss is arranged eccentrically on the upper surface of the cylindrical body of the lower grinding disc; the upper grinding disc is located above the lower grinding disc, a circular truncated cone groove is arranged in the middle of the bottom surface of the upper grinding disc, a gradually decreasing gap is formed between the upper and lower grinding discs, a feed inlet is vertically arranged in the middle of the upper surface of the upper grinding disc; the hopper is installed at the upper end of the upper grinding disc; the rotating module is used to rotate the lower grinding disc; the gap adjusting module is used to adjust the gap between the upper and lower grinding discs.

[0007] Although the above-mentioned grinder also uses the lower grinding disc as the rotating grinding disc and the upper grinding disc as the lifting grinding disc, the grinding precision of the grinder is adjusted by lowering the upper grinding disc driven by the rotating module, but the boss between the upper and lower grinding discs of the above-mentioned food grinder is only used for feeding food materials, and the grinding operation still needs to be performed at the edges of the upper and lower grinding discs. In the grinding process, it is difficult to avoid the collision between the upper and lower grinding discs due to the requirement of grinding precision, thereby generating high temperature and affecting the grinding effect. At the same time, larger food particles are difficult to be directly ground by the above-mentioned upper and lower grinding discs, which affects the grinding particle effect. SUMMARY

[0054] The lifting grinding disc is connected to the bottom of the lifting control disc 14, and the lifting grinding disc is fixedly connected with the lifting control disc 14 through screws, so as to synchronously drive the lifting of the lifting grinding disc in the lifting process of the lifting control disc 14, and the lifting control disc 14 is pressed down through the rotation of the lifting driving disc 15, the different positions of the screw block 15-1 corresponding to the screw groove 14-1, when the thicker position of the screw block 15-1 rotates to the shallower position of the screw groove 14-1 in the rotation process of the lifting control disc 14, the gap between the lifting control disc 14 and the lifting driving disc 15 increases, the lifting control disc 14 is pressed down under the condition that the lifting driving disc 15 remains at the same height, and the lifting control disc 14 is prevented from rotating under the action of the limiting block 19-1, so as to ensure that the lifting control disc 14 does not rotate synchronously under the action of friction in the rotation process of the lifting driving disc 15, and the lifting control disc 14 always only moves up and down.

[0055] The lifting control disc 14 and the lifting driving disc 15 are always tensioned through the spring expansion pin 29, so as to ensure that the lifting control disc 14 has better stability in the lifting process, so as to realize the suspension of the lifting control disc 14, and further realize the suspension of the lifting grinding disc.

[0056] The lifting driving disc 15 is arranged in the support seat 16, the lifting control disc 14 is arranged in the pressing plate 19, the support seat 16 is arranged on the pressing plate 19, the support seat 16 is fixedly connected to the pressing plate 19, the lifting driving disc 15 is rotationally connected in the support seat 16, and the lifting control disc 14 is clamped in the pressing plate 19, so as to ensure the connection stability between the lifting driving disc 15 and the lifting control disc 14 under the condition that the support seat 16 and the pressing plate 19 are fixedly connected.

[0057] The support seat 16 is formed with a mounting groove for mounting the lifting driving disc 15, the size of the mounting groove is consistent with the size of the lifting driving disc 15, so as to ensure that the outer wall of the support seat 16 is always in contact with the inner wall of the mounting groove in the rotation process of the support seat 16, so that the support seat 16 has better stability in the rotation process, and the support seat 16 abuts against the top of the lifting driving disc 15, so as to ensure that the lifting driving disc 15 always remains at the same horizontal height, thereby pressing down the lifting control disc 14 in the rotation process of the lifting driving disc 15.
