Description

Technical Field

[0001] This utility model belongs to the field of flour processing technology, and in particular relates to a continuous metering and feeding device for flour processing. Background Technology

[0002] Flour usually refers to wheat flour, which is a powdery substance formed after the endosperm of wheat seeds is milled and the bran and germ are removed. It is the main raw material for making baked goods such as bread, cakes, and biscuits. In its production and processing, the stored flour needs to be supplied to the subsequent processing equipment in a quantitative manner. However, because manual operation is cumbersome and inconvenient, a corresponding continuous metering feeding device is needed to replace the traditional manual metering feeding.

[0003] Chinese patent disclosure CN208270037U discloses an automatic flour feeding and metering device, comprising a column and a base. The base is welded to the bottom of the column, a slide rail is embedded in the inner wall of the column, a lifting column is located inside the slide rail, a lifting motor is connected to the bottom of the column, the lifting column is fixedly connected to the lifting motor, a connecting base is fixedly connected to one end of the slide rail, and the connecting base is slidably connected to the slide rail. A connecting plate is movably connected to the upper part of the connecting base, and a hinge is welded to one side of the connecting base, which is movably connected to the connecting plate via the hinge. This invention, by incorporating a lifting motor and lifting column, effectively feeds flour. The inclusion of a weighing sensor and an electric telescopic column facilitates the measurement of flour weight and allows for easy tilting of the metering box to pour out the flour. The use of a vibration motor and vibration spring effectively vibrates the metering box after flour feeding, preventing flour residue.

[0004] However, the above scheme is inconvenient for continuous quantitative feeding. It weighs the material first and then feeds it, which is an intermittent metering feeding. This results in waiting time for weighing during actual production, making it impossible to meet the feeding needs of continuous production and resulting in low efficiency. Therefore, it is necessary to design a continuous metering feeding device for flour processing. Utility Model Content

[0005] This utility model provides a continuous metering feeding device for flour processing, which aims to solve the problem that some metering feeding devices currently in use are inconvenient to continuously feed quantitatively.

[0008] Preferably, a guide platform is fixedly connected to one side of the inner wall of the spiral conveying pipe, and the guide platform is in the shape of an inverted funnel.

[0009] Preferably, the dispersing component includes: a servo motor fixedly connected to the middle position of the top of the top cover, the output end of the servo motor passing through the top cover and fixedly connected to a mounting base via a coupling; a rotating rod disposed at the bottom end of the mounting base, the bottom end of the rotating rod being fixedly connected to a spiral feeding rod; and a dispersing rod fixedly connected to the surface of the rotating rod.

[0010] Preferably, the dispersing rod is fishbone shaped, and one end of the dispersing rod is welded to the surface of the rotating rod in an integrated structure.

[0011] Preferably, a scraper is fixedly connected to the lower end of the rotating rod surface, and one side of the scraper is in contact with the inner wall of the storage bin.

[0014] Preferably, the card block and the inside of the card slot form an engaging structure, and the card slot and card block are convex in shape.

[0015] Compared with related technologies, the continuous metering and feeding device for flour processing provided by this utility model has the following beneficial effects:

[0016] 1. The weighing component detects the total weight of the screw conveyor pipe and the flour inside it. The controller calculates and subtracts the weight of the unloaded screw conveyor pipe to obtain the current weight of the flour. Simultaneously, the variable frequency motor is started to rotate the screw feeder to convey the flour material. The flour flow rate per unit time is calculated, and the actual flow rate is compared with the preset target flow rate. If the actual flow rate is less than the target flow rate, the controller controls the variable frequency motor to increase the speed of the screw feeder and speed up the feeding. If the actual flow rate is greater than the target flow rate, the variable frequency motor speed is reduced to slow down the feeding. This forms a closed-loop control, which makes the actual flow rate accurately track the target flow rate. This allows the discharge pipe to discharge material evenly, achieving continuous and high-precision quantitative feeding.

[0017] 2. The set-in dispersing component can disperse the flour inside the storage bin, preventing flour from clumping and entering the spiral conveyor pipe. At the same time, the scraper can prevent flour residue from adhering to the inner wall of the storage bin, improving the utilization rate of the flour. The spiral feed rod can convey the flour downwards in a spiral, making it easier for the flour to be discharged into the spiral conveyor pipe, ensuring continuous and high-precision flour feeding.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] Example 1

[0028] A preferred embodiment of the continuous metering and feeding device for flour processing provided by this utility model is, for example... Figure 1 , Figure 2 , Figure 3 and Figure 5As shown: A continuous metering and feeding device for flour processing includes a support frame 8; a spiral conveying pipe 12 disposed above the support frame 8, with a discharge pipe 10 fixedly connected to one side of the bottom end of the spiral conveying pipe 12, and a variable frequency motor 7 fixedly connected to one side of the spiral conveying pipe 12. The output end of the variable frequency motor 7 extends into the interior of the spiral conveying pipe 12 and is fixedly connected to a spiral feeding rod 11 via a coupling; weighing components 9 are evenly spaced and assembled at the top of the support frame 8, and the weighing components 9 are used to weigh the spiral conveying pipe 12; fixed... A fixing plate 5 is connected to one side of the top of the support frame 8. A controller 13 is fixedly connected to the lower end of one side of the fixing plate 5. A storage bin 4 is fixedly connected to the upper end of the other side of the fixing plate 5. A corrugated hose 6 is fixedly connected to the bottom end of the storage bin 4. The bottom end of the corrugated hose 6 is connected to one side of the top of the spiral conveyor pipe 12. A top cover 1 is fixedly engaged at the top of the storage bin 4. A feed hopper 3 is fixedly connected to one side of the top of the top cover 1. A dispersing component 2 is assembled on the top cover 1. The dispersing component 2 is used to disperse the flour inside the storage bin 4.

[0029] It should be noted that some existing continuous metering and feeding devices for flour processing still have certain shortcomings in actual use. The comparison document shows that they weigh first and then feed, which is an intermittent metering and feeding method. This means that in actual production, there is a waiting time for weighing, which makes it impossible to meet the feeding needs of continuous production and results in low efficiency.

[0030] In this embodiment, the weight of the fabric before it enters the spiral conveyor pipe 12 is first detected by the weighing component 9. Then, flour is added to the storage bin 4 through the feed hopper 3. The flour is then dispersed by the dispersing component 2 and conveyed into the spiral conveyor pipe 12, causing a change in the overall weight of the spiral conveyor pipe 12. Simultaneously, the spiral conveyor pipe 12 descends, stretching the corrugated hose 6. At this point, the weighing component 9 detects the total weight of the spiral conveyor pipe 12 and the flour inside it. The controller 13 calculates and subtracts the weight of the empty spiral conveyor pipe 12 to obtain the current weight of the flour. The variable frequency motor 7 is started, causing the screw feeder 11 to rotate and convey the flour material. The flow rate of flour per unit time, i.e., the feeding rate, is calculated. At the same time, the actual flow rate is compared with the preset target flow rate. If the actual flow rate is less than the target flow rate, the controller 13 controls the variable frequency motor 7 to increase the speed of the screw feeder 11 and speed up the feeding. If the actual flow rate is greater than the target flow rate, the speed of the variable frequency motor 7 is reduced to slow down the feeding. This forms a closed-loop control, which makes the actual flow rate accurately track the target flow rate. In this way, the discharge pipe 10 can discharge the material evenly, realizing continuous and high-precision quantitative feeding.

[0031] In a further preferred embodiment of this utility model, the weighing component 9 includes: a weighing seat 901 fixedly connected at equal intervals to the top of the support frame 8, and a weighing sensor 902 fixedly connected at the middle position of the top of the weighing seat 901; a telescopic seat 904 symmetrically fixedly connected to the top of the weighing seat 901, the top of the telescopic seat 904 being fixedly connected to the bottom end of the spiral conveying pipe 12, and a fixing spring 903 being wound around the surface of the telescopic seat 904, with both ends of the fixing spring 903 being fixedly connected to the top of the weighing seat 901 and the bottom end of the spiral conveying pipe 12, respectively.

[0032] In this embodiment, the weighing sensor 902 is used to detect the weight of the spiral conveying tube 12 when it is empty. When the flour enters the spiral conveying tube 12, it is detected by the weighing sensor 902, and the weight of the flour can be calculated in real time. At the same time, multiple weighing sensors 902 can improve the measurement stability and anti-interference ability.

[0033] In a further preferred embodiment of the present invention, a guide platform 14 is fixedly connected to one side of the inner wall of the spiral conveying pipe 12, and the guide platform 14 is in the shape of an inverted funnel.

[0034] In this embodiment, the inverted funnel-shaped guide platform 14 is used to prevent the flour conveyed by the spiral feed rod 11 from accumulating on the inner wall of the spiral conveying pipe 12 on one side of the discharge pipe 10, making it easier and more thorough to be discharged from the discharge pipe 10.

[0035] Example 2

[0036] Based on Example 1, a preferred embodiment of the continuous metering and feeding device for flour processing provided by this utility model is, for example... Figure 1 , Figure 2 , Figures 4 to 6 As shown: The dispersing component 2 includes: a servo motor 203 fixedly connected to the middle position of the top of the top cover 1, the output end of the servo motor 203 passing through the top cover 1 and fixedly connected to the mounting base 211 through a coupling; a rotating rod 202 set at the bottom end of the mounting base 211, the bottom end of the rotating rod 202 being fixedly connected to a spiral feeding rod 206; and a dispersing rod 204 fixedly connected to the surface of the rotating rod 202.

[0037] In this embodiment, the servo motor 203 is started to drive the rotating rod 202 to rotate, which in turn causes the dispersing rod 204 to rotate to disperse the flour, preventing the flour from clumping and causing inconvenience in entering the spiral conveying tube 12. At the same time, the rotation of the rotating rod 202 will drive the spiral feeding rod 206 to rotate, which can convey the flour downward in a spiral, making it easier for the flour in the storage bin 4 to enter the spiral conveying tube 12.

[0038] In a further preferred embodiment of the present invention, the shape of the dispersing rod 204 is fishbone shaped, and one end of the dispersing rod 204 and the surface of the rotating rod 202 are welded together as an integral structure.

[0039] In this embodiment, a fishbone-shaped dispersing rod 204 is used to facilitate the dispersing of clumps of flour.

[0040] In a further preferred embodiment of the present invention, a scraper 201 is fixedly connected to the lower end of the surface of the rotating rod 202, and one side of the scraper 201 is in contact with the inner wall of the storage bin 4.

[0041] In this embodiment, the scraper 201 can be used to avoid flour material adhering to the inner wall of the storage bin 4, thereby improving the utilization rate of flour.

[0042] In a further preferred embodiment of the present invention, a vertical rod 205 is fixedly connected to the lower end of one side of the scraper 201, and one end of the vertical rod 205 is arc-shaped.

[0043] In this embodiment, the vertical rod 205 can be used to break up the flour at the lower end of the storage bin 4.

[0044] In a further preferred embodiment of this utility model, an installation structure is provided between the rotating rod 202 and the mounting base 211. The installation structure is used to realize the assembly and disassembly of the rotating rod 202 and the mounting base 211. The installation structure includes: a slot 207 opened at the bottom end of the mounting base 211, and a fixing bolt 209 extending into the slot 207 is movably connected to one side of the mounting base 211; a locking block 208 fixedly connected to the top end of the rotating rod 202, and a bolt hole 210 that is threadedly engaged with one end of the fixing bolt 209 is opened on one side of the locking block 208.

[0045] In this embodiment, after the top cover 1 is opened, the fixing bolt 209 can be rotated with a screwdriver or other tools until it is completely disengaged from the bolt hole 210. Then, the rotating rod 202 is turned so that the locking block 208 is completely disengaged from the slot 207, which facilitates the disassembly of the rotating rod 202. This allows for the cleaning and disinfection of the scraper 201, rotating rod 202, dispersing rod 204, vertical rod 205, and spiral feeding rod 206. During installation, the locking block 208 is locked into the slot 207, and the fixing bolt 209 is screwed into the bolt hole 210 to achieve a secure installation of the rotating rod 202 and the mounting base 211.

[0046] In a further preferred embodiment of the present invention, the card block 208 and the card slot 207 form an engaging structure, and the card slot 207 and the card block 208 are convex in shape.

[0047] In this embodiment, the engagement between the inverted convex locking block 208 and the slot 207 improves the firmness and stability of the initial engagement between the rotating rod 202 and the mounting base 211.

[0048] In summary, the flour is broken up by the dispersing component 2 to avoid lumps of flour from entering the spiral conveyor pipe 12, and the continuous and quantitative feeding of flour is achieved by the weighing component 9 and the spiral feeding rod 11.
