Description

Technical Field

[0001] This utility model relates to the technical field of flour processing equipment, and specifically discloses an automatic feeding device for flour processing. Background Technology

[0002] Flour is a powdery substance made from wheat. It is the main ingredient for making baked goods such as bread, cakes, and cookies, as well as Chinese pasta dishes such as steamed buns, dumplings, and noodles. Based on the protein content, flour can be divided into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. Flour is rich in protein, carbohydrates, dietary fiber, and small amounts of vitamins and minerals, providing the human body with essential nutrients and energy. In the process of mass-producing pasta dishes using flour, automatic flour feeding devices are usually used to improve the efficiency of flour feeding and save manpower.

[0003] Chinese patent CN218560453U discloses a flour processing feeding device, including a mounting base plate, casters, a storage box, an anti-accumulation device, a pushing device, a driving device, a discharging device, and a connecting pipe. The mounting base plate houses the casters, storage box, and discharging device. The storage box contains the anti-accumulation device, pushing device, and driving device. The driving device drives the anti-accumulation device and, via a transmission belt, drives the pushing device. The storage box is connected to the discharging device via the connecting pipe. The mounting base plate supports the other devices. The casters move the device, the storage box stores flour, and the driving device drives the anti-accumulation device to reciprocate, preventing flour from accumulating inside the storage box and being unable to be discharged. The feeding device uses a drive belt to push flour from the storage box through a connecting pipe into the discharge device, which then discharges the flour. However, the anti-accumulation device in the feeding device is complex in structure, inconvenient to install and maintain. During operation, flour easily clogs the gaps in the mounting groove, the arc-shaped rack, and the output half gear, affecting the effectiveness of the anti-accumulation device and the first spiral push plate, thus affecting the feeding efficiency of the feeding device. During use, dust and other impurities in the air can easily enter from the open end of the storage box, contaminating the flour in the storage box and affecting the quality of subsequent flour processing products. Therefore, in order to solve the above problems, this utility model proposes an automatic feeding device for flour processing. Utility Model Content

[0004] The present invention aims to provide an automatic feeding device for flour processing, which avoids flour accumulation in the hopper. The scraping mechanism has a simple structure, is easy to install, use and clean and maintain, can prevent flour from clogging the components in the scraping mechanism, ensure the effectiveness of the scraping mechanism, and can prevent dust or other impurities from falling from the top of the hopper into the flour in the hopper and contaminating the flour, thus ensuring the quality of the subsequent flour processing products.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic feeding device for flour processing includes a base, a support plate, and two rollers connected to the lower sides of the support plate. A storage mechanism is located above the support plate, comprising a hopper. An arc-shaped groove is provided at the bottom inner side of the hopper, and a first spiral conveying rod is disposed inside the arc-shaped groove. First limiting holes are provided on both upper sides of the hopper. A scraping mechanism is located inside the hopper, and a protective mechanism is located above the hopper. A feeding mechanism is located at one end of the hopper. The scraping mechanism includes two symmetrically arranged scrapers, with the upper ends of the two scrapers facing away from each other. A limiting rod is connected, which passes through the interior of the first limiting hole and is slidably connected to the first limiting hole. A connecting plate is connected between the two scrapers, and a telescopic rod is connected to one side of the connecting plate. The protective mechanism includes two L-shaped plates, and a telescopic protective cover is provided above the two L-shaped plates. Mounting blocks are provided on both sides of one end of the telescopic protective cover. Slider blocks are connected to both sides of the end of the telescopic protective cover away from the mounting blocks. A handle is connected to the side of the two sliders that are far from each other. A limiting block is connected to the end of the two L-shaped plates near the feeding mechanism. The limiting block has a slot with an opening facing the handle.

[0007] As a further provision of the above scheme, the feeding mechanism includes a feeding pipe, a connecting pipe connected to the side of the feeding pipe near the hopper, and a discharge port provided at the end of the hopper near the connecting pipe. The first spiral conveying rod passes through the interior of the discharge port to facilitate the transport of flour from the hopper. A connecting pipe is connected to the end of the hopper near the connecting pipe, and the interior of the connecting pipe is connected to the interior of the hopper through the discharge port. The end of the connecting pipe away from the hopper is connected to the connecting pipe to provide support for the feeding pipe and facilitate the installation and maintenance of the connecting pipe and the feeding pipe.

[0008] As a further provision of the above solution, a support base is provided inside the connecting pipe near one end of the connecting pipe. The two ends of the first spiral conveying rod pass through the interior of the support base and the hopper respectively and are rotatably connected to the support base and the hopper respectively, which can provide stable support for the first spiral conveying rod. The end of the first spiral conveying rod away from the support base is connected to a first motor, which can provide power for the rotation of the first spiral conveying rod. The outside of the first motor is connected to a first base, and the lower end of the first base is connected to a bearing plate, which can provide stable support for the first motor and facilitate the installation and maintenance of the above components.

[0009] As a further feature of the above solution, a bracket is connected to the outer side of the telescopic rod, and the bracket is connected to the side of the hopper away from the connecting pipe, which can provide stable support for the telescopic rod.

[0010] As a further feature of the above solution, the two L-shaped plates are detachably connected to both sides of the hopper, and the two mounting blocks are detachably connected to the two L-shaped plates, facilitating the installation and maintenance of the components. Each of the two L-shaped plates has a second limiting hole inside, and the two sliders pass through the two second limiting holes and are slidably connected to them, thus limiting the movement direction of the retractable protective cover. The sliders are detachably connected to the handle, and the handle slides into the slot, allowing the handle to be engaged in the slot after the retractable protective cover is fully extended, thereby limiting the position of the handle and thus the position of the retractable protective cover, ensuring the protective effect of the retractable protective cover on the upper part of the hopper.

[0011] As a further feature of the above scheme, a second spiral conveying rod is provided inside the feeding pipe. The two ends of the second spiral conveying rod pass through the two ends of the feeding pipe and are rotatably connected to the two ends of the feeding pipe. A discharge pipe is connected to the upper end of the feeding pipe on the side away from the hopper, so that the second spiral conveying rod can transport the flour from the lower end of the feeding pipe to the upper end and discharge it through the discharge pipe. A second motor is connected to the lower end of the second spiral conveying rod, which can provide power for the rotation of the second spiral conveying rod. A second base is connected to the outside of the second motor. One end of the second base is connected to the bearing plate, which can provide stable support for the second motor and facilitate the installation and maintenance of the second motor.

[0012] As a further feature of the above solution, a controller is provided on one side above the support plate to facilitate the control of the operation of relevant components in the device.

[0013] At least one of the multiple rollers in this invention is a brake roller.

[0014] The present invention has the following beneficial effects during use:

[0015] The combination of the scraper, connecting plate, and telescopic rod in the scraping mechanism can drive the scraper to reciprocate inside the hopper through the extension and retraction of the telescopic rod. This scrapes off the flour adhering to the inner side wall of the hopper and loosens the flour accumulated in the hopper, ensuring that the first spiral conveyor rod can smoothly deliver the loosened flour out of the hopper. The combination of the two limiting rods and the first limiting hole can provide support for the entire assembly formed by the scraper and connecting plate from both sides and restrict the direction of movement of the entire assembly, so as to keep the scraper and connecting plate stable during movement.

[0016] The two L-shaped plates in the protective mechanism are detachably connected to the hopper, facilitating the installation and maintenance of the protective mechanism. The combination of the retractable protective cover, slider, and handle allows the retractable protective cover to be unfolded or folded from above the hopper before and after use, facilitating the injection of flour into the hopper and preventing dust or other powder from falling into the flour from above, keeping the flour in the hopper clean and ensuring the quality of subsequent flour processing products. The slot in the limiting block and the sliding engagement of the handle can fix the handle after the retractable protective cover is fully unfolded, thereby keeping the retractable protective cover stable and ensuring the protective effect of the retractable protective cover on the flour.

[0030] An embodiment discloses an automatic feeding device for flour processing, including a base 1, the base 1 including a support plate 11, two rollers 12 connected to the lower sides of the support plate 11, a storage mechanism 2 above the support plate 11, the storage mechanism 2 including a hopper 21, an arc-shaped groove 213 provided on the inner bottom of the hopper 21, a first spiral conveying rod 23 provided inside the arc-shaped groove 213, first limiting holes 212 provided on the upper sides of the hopper 21, a scraping mechanism 3 provided inside the hopper 21, a protective mechanism 4 provided above the hopper 21, a feeding mechanism 5 provided at one end of the hopper 21, and the scraping mechanism 3 including two symmetrically arranged scrapers 31, with a connecting rod 12 connected to the upper side of the two scrapers 31 that is far apart from each other. A limiting rod 311 passes through the interior of the first limiting hole 212 and is slidably connected to the first limiting hole 212. A connecting plate 32 is connected between the two scrapers 31. A telescopic rod 33 is connected to one side of the connecting plate 32. The protective mechanism 4 includes two L-shaped plates 41. A telescopic protective cover 42 is provided above the two L-shaped plates 41. Mounting blocks 421 are provided on both sides of one end of the telescopic protective cover 42. Slider blocks 422 are connected to both sides of the end of the telescopic protective cover 42 away from the mounting blocks 421. A handle is connected to the side of the two sliders 422 that are far away from each other. A limiting block 44 is connected to the end of the two L-shaped plates 41 near the feeding mechanism 5. A slot 441 with an opening facing the handle 43 is provided inside the limiting block 44.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, the feeding mechanism 5 includes a feeding pipe 51. A connecting pipe 511 is connected to the side of the feeding pipe 51 near the hopper 21. A discharge port 211 is provided at the end of the hopper 21 near the connecting pipe 511. The first spiral conveying rod 23 passes through the inside of the discharge port 211, which facilitates the transportation of flour from the hopper 21 out of the hopper 21. A connecting pipe 22 is connected to the end of the hopper 21 near the connecting pipe 511. The inside of the connecting pipe 22 is connected to the inside of the hopper 21 through the discharge port 211. The end of the connecting pipe 22 away from the hopper 21 is connected to the connecting pipe 511, which can provide support for the feeding pipe 51 and facilitate the installation and maintenance of the connecting pipe 22 and the feeding pipe 51.

[0032] like Figure 1 and Figure 3As shown, a support base 221 is provided inside the connecting pipe 22 near the connecting pipe 511. The two ends of the first spiral conveying rod 23 pass through the support base 221 and the hopper 21 respectively and are rotatably connected to the support base 221 and the hopper 21 respectively, which can provide stable support for the first spiral conveying rod 23.

The outside of the first motor 24 is connected to the first base 241. The lower end of the first base 241 is connected to the bearing plate 11, which can provide stable support for the first motor 24 and facilitate the installation and maintenance of the above components.

[0033] like Figure 1 and Figure 6 As shown, a bracket 34 is connected to the outer side of the telescopic rod 33. The bracket 34 is connected to the side of the hopper 21 away from the connecting pipe 22, which can provide stable support for the telescopic rod 33.

[0034] like Figure 1 , Figure 7 and Figure 8 As shown, the two L-shaped plates 41 are detachably connected to both sides of the hopper 21, and the two mounting blocks 421 are detachably connected to the two L-shaped plates 41, facilitating the installation and maintenance of the above components. Each of the two L-shaped plates 41 has a second limiting hole 411 inside. The two sliders 422 pass through the interior of the two second limiting holes 411 and are slidably connected to the second limiting holes 411, which can limit the movement direction of the retractable protective cover 42. The sliders 422 are detachably connected to the handle 43, and the handle 43 is slidably engaged with the slot 441, so that the handle 43 can be locked in the slot 441 after the retractable protective cover 42 is fully extended, thereby limiting the position of the handle 43 and thus limiting the position of the retractable protective cover 42, ensuring the protective effect of the retractable protective cover 42 on the upper part of the hopper 21.

[0035] like Figure 1 and Figure 9 As shown, a second spiral conveying rod 53 is provided inside the feeding pipe 51. The two ends of the second spiral conveying rod 53 pass through the two ends of the feeding pipe 51 and are rotatably connected to the two ends of the feeding pipe 51. The upper end of the feeding pipe 51 away from the hopper 21 is connected to the discharge pipe 52, which facilitates the second spiral conveying rod 53 to transport the flour from the lower end of the feeding pipe 51 to the upper end and discharge it through the discharge pipe 52. The lower end of the second spiral conveying rod 53 is connected to a second motor 54, which can provide power for the rotation of the second spiral conveying rod 53. The outer side of the second motor 54 is connected to a second base 541. One end of the second base 541 is connected to the bearing plate 11, which can provide stable support for the second motor 54 and facilitate the installation and maintenance of the second motor 54.

[0036] like Figure 1 As shown, a controller 6 is provided on one side above the support plate 11 to facilitate the control of the operation of related components in the device.

[0037] The automatic feeding device for flour processing disclosed in this embodiment involves injecting sufficient flour into the hopper 21 before use. Holding the two levers 43, the slider 422 slides towards the limiting block 44 through the second limiting hole 411, unfolding the retractable protective cover 42. When the levers 43 move to one side of the limiting block 44, the slider 422 continues to slide through the second limiting hole 411 until the levers 43 are engaged in the slot 441. Pushing the device causes the roller 12 to roll on the ground, moving the device to a suitable position and fixing it. The controller 6 then sequentially starts the first motor 24 and the second motor 54, causing the first motor 24 and the second motor 54 to drive the first spiral conveyor rod 23 respectively. The second spiral conveyor 53 rotates, conveying the flour in the hopper 21 into the lower end of the feeding pipe 51 via the connecting pipe 22. The flour is then conveyed from the lower end to the upper end of the feeding pipe 51 via the second spiral conveyor 53 and discharged from the feeding pipe 51 via the discharge pipe, thus realizing the feeding operation of flour. During the feeding process, the controller 6 is used to start the telescopic rod 33, which drives the two limit rods 311 to slide back and forth in the two first limit holes 212 through the connecting plate 32. This causes the scraper 31 to slide on the inner wall of the hopper 21, loosening the flour in the hopper 21 and scraping off the flour adhering to the inner wall of the hopper 21. This helps the first spiral conveyor 23 to send the loosened flour out of the hopper 21.

[0038] The automatic feeding device for flour processing disclosed in this utility model includes a controller 6, a bearing plate 11, rollers 12, a hopper 21, a connecting pipe 22, a first spiral conveyor rod 23, a first motor 24, a first base 241, a telescopic rod 33, a bracket 34, an L-shaped plate 41, a telescopic protective cover 42, a slider 422, a gripping rod 43, a feeding pipe 51, a connecting pipe 511, a discharge pipe 52, a second spiral conveyor, a second motor 54, and a second base 541. These components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
