DETAILED DESCRIPTION

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0019] like Figure 1-Figure 3 As shown, an embodiment of the present invention is proposed, which provides a grinding device for the production of grain flour to solve the problem that the existing grinding device needs to be coarsely ground once and then finely ground, which is complicated to operate and inefficient, and includes: a base frame 1, the base frame 1 is fixedly connected to a processing shell 2, and the processing shell 2 is provided with a feed inlet; two rolling rollers 201 are arranged in a mirror image and are both rotatably connected to the processing shell 2; a rotating tube 3 is rotatably connected to the base frame 1, the rotating tube 3 is fixedly connected to a movable grinding disc 4, and the movable grinding disc 4 is provided with a feeding chamber 401, the base frame 1 is fixedly connected to a fixed grinding disc 5, and the movable grinding disc 4 is in close contact with the fixed grinding disc 5; the processing shell 2 is equipped with a first gear set 6, and the first gear set 6 is used to connect the two rolling rollers 201; the processing shell 2 is equipped with a first motor 7, and the output shaft of the first motor 7 is fixedly connected to the adjacent rolling roller 201; a power mechanism is arranged on the base frame 1, and is used to make the movable grinding disc 4 and the fixed grinding disc 5 rotate relative to each other; an extrusion mechanism is arranged on the processing shell 2, and is used to extrude and grind the material.

[0020] In the above scheme, a discharge port is provided on the right side of the base frame 1, and a storage chamber (communicated with the discharge port on the base frame 1) is formed between the base frame 1, the movable grinding disc 4 and the fixed grinding disc 5, and the feed port is located on the upper side of the processing shell 2. There is a gap between the two rolling rollers 201, and the gap length is smaller than the "initial particle size" of the material (including but not limited to corn, mung bean and wheat, etc.), which is used to uniformly process the particle size of materials with different initial particle sizes. Heat dissipation plates (not shown in the figure) are installed in the movable grinding disc 4 and the fixed grinding disc 5 to dissipate the heat generated during the grinding process. The first gear set 6 is composed of four gears meshing in sequence, and the gears on the left and right sides are fixedly connected to the adjacent rolling rollers 201 respectively, and the output shaft of the first motor 7 is fixedly connected to the rolling roller 201 on the left. When using this device, the rolling roller 201 on the left is driven to rotate clockwise by the output shaft of the first motor 7, and the rolling roller 201 on the right starts to rotate counterclockwise after transmission by the first gear set 6, and the dynamic grinding disc 4 is rotated counterclockwise by the power mechanism (such as Figure 2 Taking the top view as an example), the grinding disc 4 and the fixed grinding disc 5 rotate relative to each other, and then the staff pours the material into the feed port of the processing shell 2, and then the material moves downward under the action of gravity. When the material moves downward to contact the rolling roller 201, the two rolling rollers 201 squeeze the material to crush the material, so that the particle size of the material with different original particle sizes is relatively uniform, thereby ensuring the uniformity of subsequent grinding, ensuring that the grinding work is completed in a single time, improving the grinding efficiency, and improving the subsequent grinding effect.

[0021] After the rolling roller 201 completes squeezing the material, the crushed material continues to move downward (in the processing shell 2), and then passes through the material passing cavity 401 into between the movable grinding disc 4 and the fixed grinding disc 5. Then the rotating movable grinding disc 4 grinds the material with relatively uniform particle size, and the material gradually transfers outward and is gradually ground into powder. Then the powder accumulates in the storage cavity between the base frame 1, the movable grinding disc 4 and the fixed grinding disc 5, and is finally discharged through the discharge port on the base frame 1.

[0022] like Figure 2-Figure 4 As shown, the power mechanism includes: a second motor 801, which is installed on the base frame 1, and the output shaft of the second motor 801 is fixedly connected to the first rod 802, the first rod 802 is rotatably connected to the rotating tube 3, and the first rod 802 is fixedly connected to the first spur gear 803; a composite gear 804, which is rotatably connected to the base frame 1, and the rotating tube 3 is fixedly connected to the second spur gear 805, the first spur gear 803 and the second spur gear 805 are both meshed with the composite gear 804, and the composite gear 804 is composed of two gears with different numbers of teeth, and the transmission ratio between the first spur gear 803 and the gear meshing on the composite gear 804 is greater than the transmission ratio between the second spur gear 805 and the gear meshing on the composite gear 804, that is, the rotating tube 3 and the first rod 802 have different rotational speeds.

[0023] In the above solution, the output shaft of the second motor 801 drives the first rod 802 to rotate counterclockwise (eg Figure 3 Taking the top view as an example), the first rod 802 drives the first spur gear 803 to rotate counterclockwise, the first spur gear 803 drives the second spur gear 805 to rotate counterclockwise through the composite gear 804, and the second spur gear 805 drives the movable grinding disc 4 to rotate counterclockwise through the rotating tube 3, so that the movable grinding disc 4 and the fixed grinding disc 5 rotate relative to each other, thereby grinding the material.

[0024] like Figure 2 and Figure 4-Figure 6 As shown, the extrusion mechanism includes: an extrusion shell 901, fixedly connected to and connected to the processing shell 2, a first rod 802 is spline-connected to the second rod 902, the second rod 902 is rotatably connected to the rotating tube 3, the second rod 902 is fixedly connected to an extrusion disk 903, the extrusion disk 903 is used to extrude the extrusion shell 901, a limiting groove 904 is arranged in the rotating tube 3, the second rod 902 is fixedly connected to a limiting protrusion 905, the limiting groove 904 is used to limit the limiting protrusion 905, the limiting groove 904 is a folded wave closed groove, which is used to make the extrusion disk 903 move back and forth.

[0025] In the above scheme, there is a gap between the inner wall of the extrusion shell 901 and the outer wall of the extrusion disk 903, and the areas adjacent to the outer wall of the extrusion shell 901 and the inner wall of the extrusion disk 903 are both inclined (that is, both the extrusion shell 901 and the extrusion disk 903 have truncated cone-shaped areas), and the limiting groove 904 is composed of a plurality of inclined grooves and vertical grooves connected, and the plurality of inclined grooves and vertical grooves are arranged in an interlaced manner, and the inclined grooves are arranged in a counterclockwise direction (such as Figure 6The first rod 802 (rotating tube 3) rotates counterclockwise, and the first rod 802 drives the extrusion plate 903 to rotate counterclockwise, and the extrusion plate 903 drives the limiting protrusion 905 to rotate counterclockwise. Since the rotation speed of the first rod 802 is greater than the rotation speed of the rotating tube 3, that is, the first rod 802 "rotates counterclockwise" relative to the rotating tube 3, the limiting protrusion 905 begins to slide in the adjacent inclined groove on the limiting groove 904. Under the extrusion of the inclined groove, the second rod 902 begins to rotate along the first rod 80 2 slides upward, the limiting protrusion 905 drives the extrusion plate 903 to move upward together through the second rod 902, and the gap between the extrusion plate 903 and the extrusion shell 901 gradually decreases, so that the passing material is further extruded and the preliminary grinding is completed. Since the extrusion plate 903 is accompanied by rotation during the extrusion of the material (the extrusion plate 903 and the extrusion shell 901 rotate relative to each other), that is, the extrusion plate 903 also applies a torsional force to the material, that is, the extrusion plate 903 grinds the material with a gradually changing force, and further extrude and grind the material with a variable force, so that the material is further broken, the difficulty of subsequent grinding is reduced, and the subsequent grinding effect is further improved.

[0026] like Figure 5 and Figure 6 As shown, it also includes: a sliding rod 1001, which is slidably connected to the extrusion shell 901, the sliding rod 1001 is slidably connected to the processing shell 2, the sliding rod 1001 is used to extrude adjacent areas on the processing shell 2, the area of ​​the processing shell 2 squeezed by the sliding rod 1001 is made of soft material, and an elastic element 1002 is fixedly connected between the sliding rod 1001 and the processing shell 2; a support ring 1003, which is rotatably connected to the extrusion disk 903, the support ring 1003 is fixedly connected to the sliding rod 1001, and the sliding rod 1001 is in contact with the extrusion disk 903, and is used to scrape off materials adhered to the surface of the extrusion disk 903.

[0027] In the above scheme, the area of ​​the processing shell 2 squeezed by the sliding rod 1001 is made of rubber material, and the elastic element 1002 is a spring, which is used to reset the sliding rod 1001. In the process of the extrusion plate 903 moving upward, the extrusion plate 903 drives the support ring 1003 to move upward together, and the support ring 1003 drives the sliding rod 1001 to move upward together. The sliding rod 1001 and the processing shell 2 (extrusion shell 901) slide relative to each other, the elastic element 1002 is compressed, and the sliding rod 1001 gradually squeezes the soft area on the processing shell 2 upward, so that the materials in the adjacent areas vibrate, prevent material accumulation and blockage, and ensure the normal progress of the grinding work.

[0028] like Figure 1 , Figure 7 and Figure 8As shown, it also includes: two third rods 1101, which are arranged in mirror image and are both rotatably connected to the processing shell 2; the rolling roller 201 away from the first motor 7 is connected to one of the third rods 1101 through a pulley belt transmission; the processing shell 2 is equipped with a second gear set 1102, and the second gear set 1102 is used to connect the two third rods 1101; the third rod 1101 is fixedly connected to the connecting rods 1103 arranged at intervals; the connecting rods 1103 are fixedly connected to the stirring plate 1104; the stirring plate 1104 located at the end of the third rod 1101 is folded and used to change the movement direction of the material; the stirring plate 1104 located in the middle of the third rod 1101 is a square plate; it also includes: a guide plate 12, which is fixedly connected to the bottom of the two rolling rollers 201 and used to guide the material; the guide plate 12 guides the material to the upper side of the adjacent third rod 1101 to facilitate the stirring plate 1104 to impact the material.

[0029] In the above scheme, an arc-shaped area is provided at the lower part of the processing shell 2, which covers the soft area on the processing shell 2 and is used to guide the material. The right-side crushing roller 201 is connected to the left-side third rod 1101 through a pulley belt transmission. The second gear set 1102 is composed of four gears meshing in sequence, and the gears on the left and right sides are fixedly connected to the two third rods 1101 respectively. The connecting rods 1103 on the same third rod 1101 are staggered, and the folded areas of the adjacent stirring plates 1104 on both sides of the same third rod 1101 gradually approach each other, which is used to gather the material to the middle of the lower side of the processing shell 2. The stirring plate 1104 located in the middle of the third rod 1101 is a rectangular straight plate, and the guide plate 12 is in the shape of a "human", and the symmetry axis of the guide plate 12 coincides with the symmetry axis of the two crushing rollers 201, which is used to change the position of the material in the processing shell 2 when it contacts the adjacent stirring plates 1104. In the process of the counterclockwise rotation of the right-side crushing roller 201, the crushing The pressure roller 201 transmits power to the third rod 1101 on the right side through the pulley belt, and then the third rod 1101 on the left side starts to rotate counterclockwise, and is transmitted by the second gear set 1102, and the third rod 1101 on the right side starts to rotate clockwise, and the third rod 1101 drives the adjacent connecting rod 1103 to rotate together, and the connecting rod 1103 drives the adjacent stirring plate 1104 to rotate together. In the process of the material moving downward in the processing shell 2, when the material contacts the rotating stirring plate 1104, the rotating stirring plate 1104 impacts the material in the adjacent area, so that the material moves rapidly along the impact direction (along the tangential direction of the adjacent third rod 1101), so as to impact the surface of the adjacent rolling roller 201, so that the material adhering to the rolling roller 201 falls off, and at the same time, the impact is used to disperse the material agglomerated due to rolling (the process is also accompanied by mutual impact and crushing), to ensure that the material's own state meets the grinding requirements, thereby improving the grinding effect.

[0030] After the impact, the material moves to the left and right sides of the processing shell 2, and then the material moves downward again until the material moves to the middle of the lower side of the processing shell 2 under the action of the stirring plate 1104. During the process, the materials on the left and right sides impact each other, further dispersing the agglomerated materials, thereby improving the effect of subsequent grinding.

[0031] During the mutual impact of materials on the left and right sides, the sliding rod 1001 squeezes the soft area on the processing shell 2 upward, causing the materials in the adjacent areas to vibrate, that is, changing the movement state of the materials. When the stirring plate 1104 impacts the materials, the movement diversity of the materials is increased, the degree of confusion of the materials is increased, and the dispersion effect of the agglomerated materials is thereby improved.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
