Description

Technical Field

[0001] The present invention relates to the field of flour processing, and more particularly to flour and a processing method thereof. Background Art

[0002] Screening is a crucial step in the flour processing process. Its purpose is to grade the ground flour according to particle size and remove impurities and coarse particles to ensure the flour's quality and suitability for subsequent processing. Currently, the screening mechanism in existing flour processing equipment typically consists of a screen and a drive component. A common drive method is to simply drive the screen in reciprocating linear or circular motion, causing the flour to flow across the screen surface through the movement of the screen, thereby achieving screening. However, in actual processing, due to the fineness and certain viscosity of flour particles, as the screening time increases, some flour particles tend to adhere to the screen holes, gradually causing the screen holes to become clogged. Once the screen holes become clogged, not only will the screening efficiency be reduced, causing a large amount of flour to remain on the screen surface, affecting the uniformity of the flour quality after screening, but it will also require frequent shutdowns to clean the screen, increasing the labor intensity of operators and reducing the continuous operation capacity of the entire processing equipment. Summary of the Invention

[0030] like Figure 5-6 As shown;

[0031] A flour processing device includes a rectangular frame 101, a screen 103 fixed to the rectangular frame 101, a pressure head 108 attached to the center of the lower side of the screen 103, a cone 104 fixed to the lower end of the pressure head 108, a fixed sleeve 105 is fixed around the lower side of the cone 104, a fixed sleeve 207 is fixed around the lower side of the rectangular frame 101, and an elastic band 106 is connected between each corresponding fixed sleeve 105 and fixed sleeve 207. When the screen 103 is performing a screening operation, the pressure head 108 is attached to the center of the lower side of the screen 103, and the cone 104 is located at the lower end of the pressure head 108. The elastic band 106 between the fixed sleeve 105 and the fixed sleeve 2 107 is in a stretched state, providing an upward pulling force for the cone 104 and the pressure head 108, pulling the cone 104 and the pressure head 108 downward, so that the pressure head 108 bounces toward the screen 103, and transmits the vibration force to the screen 103. At the same time, the elastic band 106 can expand and contract with the vibration, adapt to the position change of the pressure head 108 and the cone 104, ensure that the pressure head 108 vibrates the screen 103, and help prevent the screen holes from being blocked.

[0032] like Figure 5-6 As shown;

[0033] Because a round rod 109 is fixed to the lower side of the cone 104, and a plurality of balls 110 are fixed on the round rod 109 from top to bottom, the round rod 109 and the plurality of balls 110 thereon facilitate the downward pulling of the cone 104 and the pressure head 108, thereby accumulating force on the four elastic bands 106, and then the round rod 109 and the plurality of balls 110 thereon are loosened, causing the pressure head 108 to hit the screen 103, causing the screen 103 to vibrate up and down, and then causing the pressure head 108 to vibrate the screen 103 to prevent the screen holes from being blocked.

[0034] like Figure 5-6 and 8-9;

[0035] A boss 302 is fixed to the right side of the rectangular frame 101. A square rod 301 is vertically slidably connected to the boss 302. A flat rod 307 is fixed to the lower end of the square rod 301. Sliding sleeves 306 are slidably connected to the front and rear ends of the flat rod 307. A toggle lever 309 is fixed to the left side of each sliding sleeve 306. The two toggle levers 309 are clamped to the round rod 109. Elastic rods 308 are fixed to the distal ends of the two sliding sleeves 306, with the outer ends of the two elastic rods 308 fixed to the ends of the flat rod 307. The boss 302 provides vertical sliding support for the square rod 301. When the square rod 301 drives the flat rod 307 up and down, the sliding sleeves 306 slide with it. The two toggle levers 309 are clamped to the round rod 109. The elastic rods 308 exert an inward elastic force on the sliding sleeves 306, ensuring that the toggle levers 309 are always in contact with the round rod 109. When the horizontal rod 307 moves up and down, the toggle rod 309 will toggle the ball 110, and then the two toggle rods 309 will move away from each other and pass over the ball 110, and then the two toggle rods 309 will return to the other ball 110 through elastic force, and then the two toggle rods 309 will continuously toggle the round rod 109 and the multiple balls 110 thereon, so that the pressure head 108 will continuously move up and down and hit the screen 103, causing the screen 103 to vibrate up and down to prevent the screen holes from being blocked.

[0036] like Figure 5-6 and 8-9;

[0037] The lower end of round rod 109 is secured with a stopper 111, while the upper end of square rod 301 is secured with motor base 1 303. Motor base 1 303 is secured with motor 1 304. A screw 305 is secured to the output shaft of motor 1 304, and screw 305 is threadedly connected to boss 302. When motor 1 304 is activated, its output shaft rotates screw 305. Because screw 305 and boss 302 are threadedly connected, the rotation of screw 305 translates into vertical movement of motor base 1 303 and square rod 301. Square rod 301 drives flat rod 307 up and down, which in turn causes toggle rod 309 to toggle round rod 109 up and down. Stopper 111 prevents round rod 109 from dislodging between the two toggle rods 309, ensuring stable drive of round rod 109 and providing power for the vibration of pressure head 108 and screen 103.

[0038] like Figure 5-7 As shown;

[0039] Since the front and rear sides of the rectangular frame 101 are both provided with retaining edges 102, vertical rods 203 are fixed to the front and rear ends of the right side of the rectangular frame 101, two convex seats 202 are fixed to the right side of the rectangular tube 201, and the two convex seats 202 are vertically slidably connected to the two vertical rods 203 respectively. A hydraulic cylinder 1 204 is fixed on the vertical rod 203, and the movable end of the hydraulic cylinder 1 204 is fixed on the convex seat 202. The rectangular tube 201 is located above the rectangular frame 101; the retaining edges 102 on the front and rear sides of the rectangular frame 101 can prevent flour from leaking from the edge of the screen 103. The vertical rod 203 provides a vertical sliding guide for the boss 202 and the rectangular cylinder 201. When the hydraulic cylinder 204 is extended or retracted, the boss 202 and the rectangular cylinder 201 are driven to move up and down along the vertical rod 203, thereby adjusting the distance between the rectangular cylinder 201 and the screen 103. When the flour sifted out from the screen 103 needs to be poured out, the rectangular cylinder 201 is moved away from the screen 103. When sifting flour, the rectangular cylinder 201 is pressed on the screen 103 to prevent the flour from scattering during sifting.

[0040] like Figure 7 and 10 -11;

[0041] A gantry 210 is fixed to the top of the rectangular cylinder 201. A shaft 209 is fixed to the top of the shaft 209. A rotating ball 208 is fixed to the top of the shaft 209. The rotating ball 208 is rotatably connected to a ring seat 408, which is fixed to the top of the main frame 403. A base 404 is fixed to the bottom of the main frame 403. The ring seat 408 is fixed to the main frame 403, providing rotational support for the rotating ball 208. The shaft 209 is fixed to the rotating ball 208. When the rotating ball 208 rotates within the ring seat 408, it drives the shaft 209 and the rectangular cylinder 201 to move together, achieving multi-angle rotation of the rectangular cylinder 201. This, in turn, coordinates with the movement of the screen 103 and improves the uniformity of flour screening. The rotating ball 208 can simultaneously rotate while revolving, causing the screen 103 to rotate with it, effectively sifting out the flour.

[0042] like Figure 7 and 10 -11;

[0043] Since a left-tilted cylinder 206 is fixed to the upper part of the rotating ball 208, a plurality of protruding teeth 207 are arranged in a ring shape on the cylinder 206, a driving ball 410 is arranged above the rotating ball 208, and a plurality of tooth grooves 409 are arranged in a ring shape on the lower side of the driving ball 410, the driving ball 410 is fixed on the output shaft of the motor 2 411, the motor 2 411 is fixed on the motor seat 2 412, the motor seat 2 412 is vertically slidably connected to the vertical column 401, the vertical column 401 is fixed to the upper part of the main frame 403, the upper part of the main frame 403 is fixed with a hydraulic cylinder 2 402, and the movable end of the hydraulic cylinder 2 402 is fixed on the motor seat 2 412. Hydraulic cylinder 2 402 can drive motor seat 2 412 to rise and fall on vertical column 401, thereby driving motor 2 411 and driving ball 410 to rise and fall. When driving ball 410 moves downward, it presses on the inclined cylinder 206, thereby driving shaft 209, gantry 210, rectangular frame 101 and screen 103 to tilt. Then, motor 2 411 drives driving ball 410 to rotate, so that the tooth groove 409 on driving ball 410 drives the convex tooth 207 on cylinder 206, so that rotating ball 208 rotates with cylinder 206 as axis, and also rolls around ring seat 408, so that screen 103 rotates while maintaining its tilt, thereby screening out flour efficiently and quickly. When the driving ball 410 moves downward, it presses against the inclined cylinder 206. The further downward the driving ball 410 is positioned, the greater the inclination of the shaft 209, the gantry 210, the rectangular frame 101 and the screen 103. The inclination of the screen 103 is adjusted as needed. The greater the inclination of the screen 103, the greater the force during screening. The force during screening is selected as needed.

[0044] like Figure 7 and 10 -11;

[0045] Since a slot 205 is provided on the right side of the ring seat 408, a slider 406 is connected to the main frame 403 in a horizontal sliding manner, and a pressure rod 407 is fixed to the left side of the slider 406, and the pressure rod 407 can be inserted into the slot 205. A hydraulic cylinder three 405 is fixed on the upper part of the main frame 403, and the movable end of the hydraulic cylinder three 405 is fixed on the slider 406, so that the slot 205 can be aligned with the pressure rod 407, and the pressure rod 407 can be driven to be inserted into the slot 205, and the pressure rod 407 is continued to be driven to move to the left, pressing the upper end of the driving ball 410 to tilt to the left, and then driving the lower end of the shaft 209, the gantry 210, the rectangular frame 101 and the screen 103 to tilt to the right, so that the screen 103 becomes a state of lower left and higher right, which is convenient for pouring out the flour sifted out from the upper side of the screen 103.

[0046] A flour processing device is used to process a flour processing method, comprising the following steps:

[0047] S1: Pour the ground flour onto the rectangular cylinder 201 so that the flour falls on the upper side of the screen 103;

[0048] S2: Adjust the shaking amplitude of the screen 103 so that the screen 103 rotates while revolving, thereby sifting out the flour;

[0049] S3: driving the pressure head 108 to vibrate and driving the screen 103 to vibrate to prevent the screen holes from being blocked;

[0050] S4: Pour out the coarse material sieved out from the upper side of the screen 103.
