Description

Technical Field

[0001] This invention relates to the field of flour processing technology, specifically to a flour feeding device and its feeding method. Background Technology

[0002] The "flour" we usually refer to is wheat flour, which is flour made from milled wheat. Names like "high-gluten wheat flour" refer to the flour we usually talk about. Wheat flour is classified according to its properties and uses into specialty flour (such as bread flour, dumpling flour, biscuit flour, etc.), general-purpose flour (such as standard flour, enriched flour), and fortified flour (such as calcium-enriched flour, iron-enriched flour, "7+1" fortified flour, etc.); according to its purity into first-grade special flour, second-grade special flour, standard flour, and ordinary flour; and according to its gluten strength into high-gluten flour, medium-gluten flour, and low-gluten flour.

[0003] Currently, after flour is milled, it needs to be sieved to separate out the incompletely milled wheat. The semi-finished raw material needs to be fed into a fine grinding device for further milling. However, during feeding, due to the high friction between the particles and poor flowability, flour particles tend to accumulate and form blockages when transported through a conveyor pipe. Some flour also adheres to the inside of the conveyor pipe, resulting in a large amount of flour adhering to the inner wall of the pipe, which reduces the inner diameter of the pipe and slows down the feeding rate. Therefore, a flour feeding device and feeding method have been designed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a flour feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flour feeding device, comprising a feeding pipe, a support frame fixedly connected to the upper end of one side of the feeding pipe, a servo motor fixedly connected to one side of the upper end of the support frame, an installation arm fixedly connected to the output end of the servo motor, a support rod rotatably connected to the end of the installation arm away from the servo motor, the support rod passing through the installation arm, an installation block fixedly connected to the lower end of the support rod, an installation frame snapped into the lower end of the installation block, an installation rod fixedly connected to the middle of the lower end of the installation frame, two scrapers symmetrically fixedly connected to the side wall of the installation rod, a gear fixedly connected to the middle of the upper end of the support rod, a fixed rod fixedly connected to the lower end of the support frame, a rotating ring fixedly connected to the lower end of the fixed rod, a meshing tooth fixedly connected to one side of the rotating ring, and a stop bar fixedly connected to the upper end of the rotating ring near the meshing tooth.

[0006] When flour enters the feeding pipe, the mounting arm driven by a servo motor rotates, causing the mounting arm to rotate a support rod on one side. The support rod then rotates the mounting rod at the lower end, causing the mounting rod to move the scraper in a circular trajectory. This scrapes away the flour adhering to the side wall of the feeding pipe, thus preventing the feeding pipe from being blocked or contaminated by flour and affecting its next use.

[0007] In a further embodiment, the gear consists of two half gears arranged symmetrically. A limiting rod is fixedly connected to the middle of the upper end of the gear, and a limiting plate is fixedly connected to the limiting rod. The limiting plate is rhomboid in shape and is blocked by a stop rod when it rotates.

[0008] In a further embodiment, a rotating rod is fixedly connected to the lower end of the mounting arm near the servo motor, a mounting frame is fixedly connected to the lower end of the rotating rod, and a dredging roller is fixedly connected to the lower end of the mounting frame. A guide groove is provided on the outer side of the dredging roller, and the guide grooves are evenly distributed.

[0009] The rotating rod drives the mounting frame to rotate, which in turn drives the unblocking roller to rotate. This causes the unblocking roller to rotate as the flour is being fed, and it also limits the flow of the flour to prevent it from piling up, thus separating the flour during feeding.

[0010] In a further embodiment, a fixing groove is provided on one side of the mounting block, an elastic sheet is fixedly connected in the fixing groove, and a locking block is fixedly connected on the side of the elastic sheet away from the inner wall of the fixing groove. The locking block and the fixing groove are slidably connected, and the locking block is in the shape of an inverted trapezoid, and the locking block engages with the mounting frame.

[0011] The mounting frame is attached to the mounting block, which allows the mounting rod and scraper at the bottom of the mounting frame to be quickly removed from the bottom of the mounting block when cleaning or replacement is needed, thus facilitating the replacement of the scraper.

[0012] In a further embodiment, a slot is provided in the mounting frame, and a push plate is slidably connected to one side of the slot.

[0013] In a further embodiment, the rotating ring is located at the top of the feed tube, and a fixing hole is provided in the middle of the rotating ring. The output end of the servo motor passes through the fixing hole and is fixedly connected to the mounting arm.

[0014] In a further embodiment, a number of scraping teeth are fixedly connected to the side of the scraper away from the mounting rod, and the scraping teeth on the two scrapers are staggered.

[0015] The designed scraper teeth can effectively scrape off the flour adhering to the inner wall of the feeding pipe when the scraper moves, keeping the feeding pipe clean. The staggered distribution of the scraper teeth allows the other half of the scraper teeth to scrape off the part missed by the previous scraper after the scraper is switched, so that the scraper teeth can scrape off all the flour on the inner wall of the feeding pipe and feed the material.

[0016] In a further embodiment, a protective shell is fixedly connected to the support frame, and the protective shell is circular.

[0017] Preferably, the feeding method based on the above-mentioned flour feeding device includes the following steps:

[0018] A1. Pour the incompletely crushed flour back into the feeding pipe. During the process of the flour entering the feeding pipe, start the servo motor, which drives the mounting arm to rotate. The mounting arm drives the support rod to rotate, and the support rod drives the lower mounting rod to rotate around the center of the servo motor output end. This also drives the scraper to rotate, so that the scraper can scrape off the flour adhering to the side wall of the feeding pipe.

[0019] A2. The support rod drives the gear to rotate around the center of the servo motor output end. When the gear rotates, it meshes with the meshing teeth, causing the gear to rotate 180 degrees. This causes the scraper connected to the support rod at the lower end to rotate around the center of the support rod, and the two scrapers to exchange positions, so that the scraper continues to scrape the flour from the remaining part of the inner wall of the feed tube.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention relates to a flour feeding device. A support rod, driven by a rotating mounting arm inside the feeding pipe, is continuously scraped by a scraper mounted at the lower end of the support rod. This scrapes away flour adhering to the inner wall of the feeding pipe during the feeding process, ensuring unobstructed flow and preventing contamination that could affect future use. This reduces subsequent cleaning steps and improves cleaning efficiency. Furthermore, the rotating scraper breaks up the flour during feeding, preventing it from rubbing together and clumping.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figure 1-6 This embodiment provides a flour feeding device and its feeding method, including a feeding pipe 1, a support frame 2 fixedly connected to the upper end of one side of the feeding pipe 1, and a protective shell 21 fixedly connected to the support frame 2. Figure 1 As shown, the protective shell 21 is circular and is used to cover the feed pipe 1 to prevent dust from directly entering the feed pipe 1. A fixing rod 41 is fixedly connected to the lower end of the support frame 2, and a rotating ring 4 is fixedly connected to the lower end of the fixing rod 41. The rotating ring 4 is located at the upper end of the feed pipe 1, and several meshing teeth 42 are fixedly connected to one side of the rotating ring 4, such as... Figure 4 As shown, the meshing teeth 42 are used to drive the gear 7 to rotate when the gear 7 rotates. A stop bar 43 is fixedly connected to the upper end of the rotating ring 4 near the meshing teeth 42, as shown. Figure 4 As shown, the stop lever 43 is used to contact the limiting plate 8 on the gear 7 when it rotates, and to block the limiting plate 8. After the limiting plate 8 is blocked, the gear 7 is assisted in meshing with the meshing teeth 42, causing the gear 7 to rotate.

[0032] A servo motor 3 is fixedly connected to the upper end of the support frame 2 away from the side wall of the feed pipe 1. The output end of the servo motor 3 is fixedly connected to the mounting arm 5. The end of the mounting arm 5 away from the servo motor 3 is rotatably connected to the support rod 6, and the support rod 6 passes through the mounting arm 5 vertically. The lower end of the support rod 6 is fixedly connected to the mounting block 61. A fixing groove is opened on one side of the mounting block 61. An elastic sheet 62 is fixedly connected in the fixing groove. A locking block 63 is fixedly connected on the side of the elastic sheet 62 away from the inner wall of the fixing groove. The locking block 63 and the fixing groove are slidably connected. The locking block 63 is in the shape of an inverted trapezoid, which facilitates the insertion and connection of the mounting block 61 into the mounting frame 9. During the process, the locking block 63 is squeezed by the inner wall of the mounting frame 9 and moves laterally into the fixing groove. The locking block 63 engages with the mounting frame 9, while a push plate 91 is slidably connected to one side of the mounting frame 9.

[0033] After the flour feeding is completed, the scraper 11 needs to be cleaned or replaced with another type of scraper 11, such as installing a cleaning brush on the side of the scraper 11 to clean the feeding pipe 1. Therefore, the scraper 11 needs to be disassembled. At this time, the push plate 91 can be pushed to move the locking block 63, so that the locking block 63 enters the fixing groove, so that the locking block 63 squeezes the elastic sheet 62 to shrink, and so that the locking block 63 no longer locks the mounting frame 9, so that the mounting frame 9 separates from the mounting block 61. Then the mounting frame 9 is removed, and the scraper 11 is removed together, so as to replace or clean the scraper 11.

[0034] During installation, the mounting frame 9 is moved upward from the lower end of the mounting block 61, so that the mounting block 61 is inserted into the mounting frame 9. During the insertion process, the locking block 63 exposed on one side of the mounting block 61 is squeezed by the inner wall of the mounting frame 9 and enters the fixing groove. At the same time, the movement of the locking block 63 will squeeze the elastic sheet 62 to contract. When the mounting block 61 descends to the bottom of the mounting frame 9, the elastic sheet 62 returns to its original state and drives the locking block 63 to return to its original state, so that the locking block 63 is exposed from the fixing groove and engages with the mounting frame 9. Thus, the mounting rod 10 and the scraper 11 are fixed to the lower end of the support rod 6, and the installation is completed.

[0035] The mounting block 61 is used to snap onto the mounting frame 9, so that the mounting rod 10 and scraper 11 at the lower end of the mounting frame 9 can be quickly removed from the lower end of the mounting block 61 when cleaning or replacement is required, thus facilitating the replacement and use of the scraper 11.

[0036] The mounting frame 9 is fixedly connected to the mounting rod 10 at the lower end. Two scrapers 11 are symmetrically fixedly connected to the side wall of the mounting rod 10. The two scrapers 11 are symmetrically arranged, and the scraper 11 near the side wall of the feed pipe 1 is in contact with the inner wall of the feed pipe 1.

[0037] Specifically, the servo motor 3 starts and drives the mounting arm 5 to rotate. The mounting arm 5 drives the support rod 6 on one side to rotate around the center of the output end of the servo motor 3, and the support rod 6 drives the lower mounting rod 10 to move, so that the mounting rod 10 moves in a circular trajectory inside the feeding tube 1. The mounting rod 10 drives the scraper 11 to move, so that the scraper 11 scrapes off the flour adhering to the inner wall of the feeding tube 1.

[0038] When flour enters the feeding pipe 1, the mounting arm 5 driven by the servo motor 3 rotates, causing the mounting arm 5 to drive the support rod 6 on one side to rotate. The support rod 6 then drives the mounting rod 10 at the lower end to rotate, causing the mounting rod 10 to drive the scraper 11 to move in a circular trajectory. The scraper 11 scrapes off the flour adhering to the side wall of the feeding pipe 1, thereby preventing the feeding pipe 1 from being blocked or contaminated by flour, which would affect its next use.

[0039] Furthermore, as the scraper 11 continues to rotate in a circular motion, the flour feeding will also be blocked by the scraper 11, causing the flour that has accumulated into clumps to break up, preventing the feeding pipe 1 from being blocked during feeding, thus making the flour feeding more efficient and smooth.

[0040] The middle part of the gear 7 is fixedly connected to the upper end of the support rod 6. The gear 7 consists of two half gears, such as... Figure 4 As shown, a limiting rod 71 is fixedly connected to the middle of the upper end of gear 7, and a limiting plate 8 is fixedly connected to the limiting rod 71. The limiting plate 8 is rhomboid in shape, as shown. Figure 4 As shown.

[0041] When the mounting arm 5 drives the support rod 6 to rotate, the support rod 6 drives the gear 7 to move, causing the gear 7 to rotate around the center of the output end of the servo motor 3 and move along the edge of the rotating ring 4. When the gear 7 rotates to the position of the meshing tooth 42, it is meshed by the meshing tooth 42, causing the gear 7 to rotate around its own center. When the gear 7 moves, the limiting plate 8 also moves. When the limiting plate 8 moves to the position of the stop bar 43, it is blocked by the stop bar 43, causing the limiting plate 8 to rotate and assisting the gear 7 to rotate 180 degrees. This causes the gear 7 to drive the support rod 6 to rotate, and the support rod 6 drives the mounting rod 10 at the lower end to rotate, and drives the two scrapers 11 to move, so that the positions of the two scrapers 11 are swapped. During the rotation, the scrapers 11 rotate and throw off the flour on the scrapers 11. The other scraper 11 rotates and approaches the feed pipe 1, continuing to scrape off the flour on the inner wall of the feed pipe 1.

[0042] Furthermore, several scraping teeth are fixedly connected to both scraper blades 11, such as... Figure 3 As shown, the scraping teeth on the two scrapers 11 are staggered.

[0043] The scraper teeth can effectively scrape off the flour adhering to the inner wall of the feed pipe 1 when the scraper 11 moves, keeping the feed pipe 1 clean. The staggered scraper teeth can also scrape off the part missed by the previous scraper 11 after the scraper 11 is switched, so that the scraper teeth can scrape off all the flour on the inner wall of the feed pipe 1 and feed the material.

[0044] The lower end of the mounting arm 5 near the servo motor 3 is fixedly connected to the rotating rod 12. The lower end of the rotating rod 12 is fixedly connected to the mounting frame 13. The lower end of the mounting frame 13 is fixedly connected to the unblocking roller 14. The unblocking roller 14 has guide grooves on its outer side, and the guide grooves are evenly distributed.

[0045] When the mounting arm 5 rotates, it will also drive the rotating rod 12 to rotate, which in turn drives the mounting frame 13 to rotate. The mounting frame 13 then drives the unblocking roller 14 to rotate, which in turn rotates the unblocking roller 14 when the flour is being fed, and limits the flour to prevent it from piling up, thus separating the flour feeding.

[0046] The specific usage method is as follows: put the incompletely crushed flour into the feeding tube 1, then start the servo motor 3. The servo motor 3 drives the mounting arm 5 to rotate. The mounting arm 5 drives the support rod 6 on one side to rotate around the center of the output end of the servo motor 3, and the support rod 6 drives the lower mounting rod 10 to move. The mounting rod 10 moves in a circular trajectory inside the feeding tube 1. The mounting rod 10 drives the scraper 11 to move, so that the scraper 11 scrapes off the flour adhering to the inner wall of the feeding tube 1. Simultaneously, when the mounting arm 5 drives the support rod 6 to rotate, the support rod 6 drives the gear 7 to move, causing the gear 7 to rotate around the center of the output end of the servo motor 3 and move along the edge of the rotating ring 4. When the gear 7 rotates to the position of the meshing tooth 42, it is meshed by the meshing tooth 42, causing the gear 7 to rotate around its own center. When the gear 7 moves, the limiting plate 8 also moves. When the limiting plate 8 moves to the position of the stop bar 43, it is blocked by the stop bar 43, causing the limiting plate 8 to rotate and assisting the gear 7 to rotate 180 degrees. This causes the gear 7 to drive the support rod 6 to rotate, and the support rod 6 drives the mounting rod 10 at the lower end to rotate, and drives the two scrapers 11 to move, so that the positions of the two scrapers 11 are swapped. During the rotation, the scrapers 11 rotate and throw off the flour on the scrapers 11. After the other scraper 11 rotates, it approaches the feed pipe 1 and continues to scrape off the flour on the inner wall of the feed pipe 1.

[0047] The mounting arm 5 will also drive the rotating rod 12 to rotate, which in turn drives the mounting frame 13 to rotate. The mounting frame 13 drives the unblocking roller 14 to rotate, so that the unblocking roller 14 rotates when the flour is being fed and limits the flour to prevent it from piling up, thus separating the flour feeding.
