Description

Technical Field

[0001] The present invention relates to the technical field of grain processing machinery, and specifically to a production and processing device for flour. Background Art

[0002] Traditional flour production and processing equipment mainly consists of a feeding device, a grinding system, a screening device, and a power transmission component. During production, wheat is evenly fed into the grinding system through the feeding device. By utilizing the rotational speed difference between the rollers and the tooth pattern to shear and extrude the wheat grains, the bran is separated from the endosperm and ground into flour. The ground mixture is separated by the screening device according to particle size. Coarse particles are returned to the grinding system for further processing, while fine powder is collected as the finished product.

[0003] However, in traditional flour processing equipment, the feeding of wheat mainly relies on gravity free fall or simple screw conveyance, lacking an accurate flow control mechanism. Due to the unstable raw material flow, it is easy to cause material accumulation or interruption of flow in the gap between the grinding rollers, which not only reduces the grinding efficiency but also exacerbates local wear. In terms of adjusting the grinding accuracy, most equipment uses grinding rollers with a fixed spacing, or adjusts the roller spacing through mechanical structures such as manual knobs and bolts. The operation is cumbersome and the accuracy is difficult to guarantee, unable to meet the diverse market demands. During processing, the equipment mostly uses simple cloth bag dust removal or natural sedimentation methods to handle the dust generated during the production process, which has problems such as low filtration efficiency and easy blockage, requiring frequent replacement of the cloth bag and high operation and maintenance costs. And when cleaning the sieve mesh of traditional equipment, it usually adopts manual knocking after stopping the machine, which not only consumes a lot of time but also damages the sieve mesh due to improper operation, severely restricting the continuous and automated operation of the flour production line.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Please see the attached Figure 1 -Attached Figure 3, an embodiment of the present invention provides a production and processing device for flour, including a workbench 1. A support frame 2 is fixedly connected to the upper side of the workbench 1. A connection channel 3 is fixedly connected to the upper side of the support frame 2. A feed hopper 4 is fixedly connected to the upper side of the connection channel 3. A spacing adjustment component 5 is arranged on the connection channel 3. The spacing adjustment component 5 includes a connecting plate 51. The connecting plate 51 is fixedly connected to the front and rear sides of the connection channel 3. An electric push rod 52 is fixedly installed on the right side of the connecting plate 51. The telescopic end of the electric push rod 52 is fixedly connected to a fixed block 53. The front side of the fixed block 53 is fixedly connected to a second motor 9. The fixed block 53 is fixedly connected to a rotating shaft 10. The rotating shaft 10 is slidably connected inside a chute 54. The chute 54 is opened inside the connection channel 3. A second grinding roller 11 is slidably connected to the left side of a first grinding roller 7. A first motor 6 is fixedly installed on the front side of the support frame 2. The output end of the first motor 6 is fixedly connected to a connecting shaft 8. A linkage component 12 is arranged on the outer side of the connecting shaft 8. The linkage component 12 includes a first synchronous pulley 121. The first synchronous pulley 121 is fixedly connected to the outer side of the connecting shaft 8. A dialing plate 124 is arranged inside the feed hopper 4. A fixed shaft 125 is fixedly connected inside the dialing plate 124. A second synchronous pulley 122 is fixedly connected to the front side of the fixed shaft 125. The first synchronous pulley 121 and the second synchronous pulley 122 are drivingly connected by a synchronous belt 123 on the outer sides. A first grinding roller 7 is fixedly connected to the outer side of the connecting shaft 8. A second grinding roller 11 is arranged on the right side of the first grinding roller 7. A rotating shaft 10 is fixedly connected inside the second grinding roller 11. A second motor 9 is arranged on the front side of the rotating shaft 10;

[0030] Specifically, the harvested wheat with impurities uniformly falls into the device from the feed hopper 4. After the first motor 6 is started, the connecting shaft 8 at its output end forms a transmission system through the first synchronous pulley 121, the synchronous belt 123 and the second synchronous pulley 122 of the linkage component 12, driving the dialing plate 124 inside the feed hopper 4 to rotate at a constant speed. The blades of the dialing plate 124 are evenly distributed, generating a uniform pushing force on the wheat during the rotation process, avoiding the accumulation or fluctuating feeding of raw materials, and ensuring that the wheat flow rate entering the grinding link is stable and controllable. When the wheat vertically falls through the connection channel 3 and enters the grinding link, the first grinding roller 7 and the second grinding roller 11 rotate in opposite directions under the drive of the first motor 6 and the second motor 9, forming a shear grinding area. The surfaces of the two rollers are made of special alloy materials and processed with staggered tooth patterns. Through the extrusion force and friction force generated by the relative movement, the wheat grains are gradually crushed. When it is necessary to adjust the fineness of the flour, the electric push rod 52 drives the second grinding roller 11 to accurately slide along the chute 54 through the fixed block 53, and the fine adjustment of the distance between the two rollers can be completed within a few seconds, ensuring that the spacing adjustment accuracy meets the production requirements of different flour categories. Whether it is the coarse-grained grinding required for high-gluten flour for making bread or the fine grinding required for low-gluten flour for pastries, the mechanism can quickly switch.

[0031] Please refer to the attached Figure 4 - attached Figure 6, a screen mesh 14 is provided inside the support frame 2, an adsorption assembly 13 is provided above the screen mesh 14. The adsorption assembly 13 includes a conical funnel 131 which is fixedly connected inside the connecting channel 3. A neodymium iron boron permanent magnet 132 is fixedly connected to the inner wall of the conical funnel 131. The conical funnel 131 is arranged below the first grinding roller 7 and the second grinding roller 11. A collection tank 20 is fixedly installed below the screen mesh 14. The air collection seat 183 is slidably connected between the screen mesh 14 and the collection tank 20. A vibration motor 15 is fixedly installed on the right side of the screen mesh 14. A connecting rod 16 is fixedly connected to the inner wall of the support frame 2. A spring 17 is fixedly connected to the outside of the screen mesh 14. The lower side of the spring 17 is fixedly connected to the upper side of the connecting rod 16. A conveyor belt 19 is fixedly installed on the right side of the support frame 2. A centralized box 23 is arranged on the right side of the workbench 1. A dust collection assembly 21 is arranged at the rear of the workbench 1. The dust collection assembly 21 includes a dust collection hood 211 which is fixedly installed on the inner top of the support frame 2. A dust collection pipe 212 is fixedly communicated above the dust collection hood 211. The side of the dust collection pipe 212 away from the dust collection hood 211 is fixedly connected to a collection box 214. The collection box 214 is fixedly installed at the rear of the workbench 1. A drawer 215 is slidably connected inside the collection box 214. A blower 213 is fixedly installed on the left side of the collection box 214;

[0032] Specifically, the ground materials fall into the conical funnel 131. The neodymium iron boron permanent magnet 132 embedded in the inner wall of the funnel forms a high-intensity magnetic field area. When ferromagnetic impurities such as iron nails and iron wires carried by wheat flow through with the materials, they will be quickly adsorbed by the magnet and retained on the funnel wall, realizing the efficient separation of metal foreign matters from the raw materials, and then falling into the screen mesh 14. The vibration motor 15 generates high-frequency vibration, driving the screen mesh 14 to make reciprocating motion under the elastic support of the spring 17 and the connecting rod 16. The screen mesh is made of food-grade stainless steel, and the density of the screen holes is customized according to the flour precision requirements. During the vibration process, the flour particles meeting the particle size requirements pass through the screen holes and fall into the collection tank 20 below, while large particle impurities such as bran and wheat germ slide along the inclination angle of the screen mesh to one side and finally fall onto the conveyor belt 19 through the diversion port. At the same time, the blower 213 of the dust collection assembly 21 keeps running, forming a negative pressure air flow through the dust collection hood 211 in the screening area, sucking the fine dust raised during grinding and screening into the dust collection pipe 212, and realizing the separation of dust and air through the filtering device in the collection box 214. The purified air can be recycled or discharged up to standard, and the drawer 215 regularly collects the dust for unified treatment.

[0033] Please refer to the appendix Figure 7 - appendix Figure 8, a cleaning component 18 is arranged on the lower side of the screen 14. The cleaning component 18 includes an air compressor 181. The air compressor 181 is fixedly installed on the left side of the workbench 1. The output end of the air compressor 181 is fixedly communicated with a connecting pipe 182. An electric slide rail 185 is fixedly installed on the upper side of the workbench 1. An electric slider 186 is fixedly installed inside the electric slide rail 185. The upper side of the electric slider 186 is fixedly connected with a connecting frame 187. The inner side of the connecting frame 187 is fixedly connected with a gas collecting seat 183. The upper side of the gas collecting seat 183 is fixedly connected with a nozzle 184. A controller 22 is fixedly installed on the front side of the support frame 2. The controller 22 is electrically connected to the electric push rod 52, the first motor 6, the second motor 9, the vibration motor 15, the air compressor 181, the electric slide rail 185 and the fan 213;

[0034] Specifically, when the screen vibrates abnormally and becomes blocked, the air compressor 181 starts and outputs high-pressure gas, which is transported to the gas collecting seat 183 through the connecting pipe 182. The nozzles 184 on the gas collecting seat 183 are arranged in an array and can cover the entire bottom surface of the screen. Driven by the electric slide rail 185 and the electric slider 186, the nozzle group reciprocates along the length direction of the screen, and the high-speed air flow ejected impacts the screen holes from below the screen, blowing the blocked impurities such as bran away in the reverse direction. The whole cleaning process does not require shutdown, and the spraying pressure and moving speed are automatically adjusted by the controller 22 according to the degree of blockage to ensure that the screen is not damaged while cleaning efficiently.

[0035] Working principle: When using this device, the harvested wheat with impurities enters the equipment through the feed hopper 4. After the first motor 6 starts, the connecting shaft 8 connected to its output end rotates. Through the first synchronous pulley 121, the synchronous belt 123 and the second synchronous pulley 122 in the linkage assembly 12, the stirring plate 124 inside the feed hopper 4 is driven to rotate, uniformly controlling the wheat feeding speed. The wheat falls between the first grinding roller 7 and the second grinding roller 11. The first motor 6 drives the first grinding roller 7 to rotate, and the second motor 9 drives the second grinding roller 11 to rotate. The two rollers move towards each other to achieve grinding. When it is necessary to adjust the fineness of the flour, the fixed block 53 is pushed by the telescopic electric push rod 52, thereby driving the second grinding roller 11 to slide on the left side of the first grinding roller 7, precisely adjusting the distance between the two grinding rollers, and grinding the wheat into flour particles of different precisions. At the same time, when the wheat falls through the connecting channel 3, the neodymium iron boron permanent magnet 132 in the adsorption assembly 13 is fixed on the inner wall of the conical funnel 131, which can effectively adsorb ferromagnetic impurities such as iron nails and iron wires mixed in the wheat, completing the preliminary purification of the raw materials;

[0036] The adsorbed wheat flour falls onto the sieve 14, and the vibration motor 15 fixed on the outer side of the sieve 14 starts to work. Cooperating with the spring 17 connected between the outer side of the sieve 14 and the connecting rod 16 on the inner wall of the support frame 2, the sieve 14 generates high-frequency vibration. The refined flour meeting the particle size requirements falls through the sieve holes, and large particle impurities such as bran and wheat germ remain on the sieve 14. At the same time, the fan 213 works, and the flour dust generated during the grinding process is sucked into the drawer 215 inside the collection box 214 through the dust suction hood 211 and the dust suction pipe 212, avoiding dust flying in the workshop. The impurities fall onto the conveyor belt 19 and are conveyed to the centralized box 23 on the right side of the workbench 1 to complete the collection;

[0037] The collection trough 20 fixed under the sieve 14 receives the falling refined flour. When it is necessary to clean the sieve 14, the air compressor 181 is started. The high-pressure gas output by the air compressor 181 enters the air collection seat 183 through the connecting pipe 182 and then is sprayed out through the nozzle 184. The electric slide rail 185 drives the electric slider 186, the connecting frame 187 and the air collection seat 183 to reciprocate between the sieve 14 and the collection trough 20 to perform reverse blowing and cleaning on the sieve 14 to prevent the sieve holes from being blocked by impurities such as bran.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
