Description

Technical Field

[0001] This invention relates to the field of feed dispensing equipment technology, and in particular to a rotary feed precision metering alarm dispensing device and its control method. Background Technology

[0002] Feed is made from a variety of raw materials formulated according to a specific formula. The batching process is the core link in feed production, and the accuracy of batching directly determines the quality of the final product. Currently, most feed processing plants still require manual operation for their batching systems, resulting in poor automation. Furthermore, a single system can generally only prepare one type of finished feed, severely limiting the processing scope, flexibility, and efficiency, which significantly impacts production progress.

[0003] In the field of micro-feeding, due to the small quantities and diverse types of raw materials such as minerals and pharmaceuticals, the feeding process has long relied on manual labor. Manual micro-feeding suffers from drawbacks such as high labor costs, large weighing errors, and a tendency to produce incorrect feed, becoming a bottleneck in feed production technology and a major technical challenge that the feed industry urgently needs to address. Furthermore, the micro-raw materials required for each batch of product are characterized by their diverse types, varying quantities, and significant differences in physicochemical properties, further increasing the difficulty of automated feeding.

[0004] Therefore, a rotary feed precision metering alarm dispensing device and its control method are proposed. Summary of the Invention

[0005] In view of this, the present invention provides a rotary feed precision metering alarm dispensing device and its control method to solve or alleviate one of the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this invention is implemented as follows: A rotary feed precision metering and alarm dispensing device includes a base, a support plate fixedly connected to the top of the base, a drive motor installed at the bottom of the support plate, a bracket rotatably connected to the top of the support plate, the output shaft of the drive motor fixedly connected to the bracket, feed bins uniformly fixedly connected to the outer side wall of the bracket, a discharge port provided at the bottom of the feed bins, a discharge valve installed on the discharge port, a base plate fixedly connected to the base, a weighing sensor installed on the top of the base plate, a connecting frame fixedly connected to the bracket, and a control panel installed on one side of the connecting frame.

[0007] A further preferred embodiment: the top of the feed bin is hinged to a top cover, and a handle is fixedly connected to the top of the top cover.

[0008] A further preferred embodiment: the top of the weighing sensor is fixedly connected to an electric lifting platform, and the top of the electric lifting platform is provided with a positioning groove.

[0009] A further preferred embodiment: a material cylinder is provided on the top of the electric lifting platform, and a display is mounted on the surface of the material cylinder.

[0010] A further preferred embodiment: the control panel includes a controller body, an audible and visual alarm, a display screen, and operation buttons; An audible and visual alarm is installed on the top of the controller body, a display screen is installed on the front surface of the controller body, and several operation buttons are installed on the front surface of the controller body.

[0011] A further preferred embodiment: the controller body is electrically connected to the audible and visual alarm and the display screen.

[0012] A further preferred embodiment: the controller body is connected to the weighing sensor via signal connection.

[0013] A further preferred embodiment: the controller body is electrically connected to the drive motor and the discharge valve.

[0014] In addition, the present invention also provides a control method for a rotary feed precision metering alarm dispensing device, comprising the following steps: Step S1: Set the target feed weight and tolerance range for each type of feed through the control panel, and select the feed bin that needs to be discharged. Step S2: Start the drive motor to rotate the support frame so that the discharge port of the selected feed bin is aligned with the top of the feed cylinder on the electric lifting platform; Step S3: Open the discharge valve on the discharge port to allow the feed to fall into the feed cylinder. At the same time, the weighing sensor collects the weight data of the falling feed in real time and transmits it to the main body of the controller. Step S4: The controller compares the real-time collected weight data with the set target feed weight. When the real-time weight reaches the target weight, the discharge valve is closed to stop the feed silo from discharging. Step S5: The controller determines whether the weight of the ingredients is within the set tolerance range. If it exceeds the tolerance range, it triggers an audible and visual alarm and displays the out-of-tolerance information on the display screen. Step S6: Repeat steps S2 to S5 to complete the batching of the remaining feed bins in sequence until all target feed batches are completed.

[0015] A further preferred embodiment is that when the barrel is unloaded, the controller automatically reads the zero-point value of the weighing sensor and deducts this zero-point value during subsequent weighing processes.

[0016] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention, by setting up a turntable-type support structure, uniformly and fixedly connects multiple feed bins on the outer wall of the support. With the help of a drive motor to drive the support to rotate, it can realize the rapid switching and sequential feeding of different feed bins. This solves the problem that traditional feeding systems can only prepare one type of finished feed and have a limited processing range, thus improving the flexibility of feeding and production efficiency.

[0017] Second, this invention installs a weighing sensor on the base and fixes an electric lifting platform with a positioning groove on the top of the weighing sensor. In conjunction with the discharge valve on the discharge port, the weight data of the falling material is collected in real time during the batching process and transmitted to the controller body to achieve precise control. When the real-time weight reaches the target weight, the discharge valve is immediately closed, avoiding batching errors caused by delayed control and improving the metering accuracy.

[0018] Third, this invention integrates a controller body, an audible and visual alarm, a display screen, and operation buttons through a control panel. The controller body is connected to the weighing sensor signal and electrically connected to the drive motor and the discharge valve. When the weight of the batching exceeds the set tolerance range, the audible and visual alarm automatically sends an alarm signal and displays the out-of-tolerance information on the display screen, realizing real-time monitoring and out-of-tolerance alarm functions for the batching process, preventing quality problems caused by batching errors, and ensuring the quality and safety of the batching.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, this embodiment of the invention provides a rotary feed precision metering and alarm dispensing device, including a base 1. A support plate 2 is fixedly connected to the top of the base 1, and a drive motor 3 is installed at the bottom of the support plate 2. A bracket 4 is rotatably connected to the top of the support plate 2. The output axis of the drive motor 3 passes upward through the support plate 2 and is fixedly connected to the bottom center of the bracket 4. When the drive motor 3 starts, it can drive the bracket 4 to rotate relative to the support plate 2 around its own axis in a horizontal plane. The bracket 4 is a regular polygon, and multiple feed bins 5 are uniformly fixedly connected to the outer wall of the bracket 4 along the circumferential direction. Each feed bin 5 is used to contain one type of feed raw material. Each feed bin 5 rotates synchronously with the bracket 4, so that different feed bins 5 can be switched to the dispensing station in sequence. Each feed bin 5 has a discharge port 8 at its bottom, and a discharge valve 9 is installed on the discharge port 8. The discharge valve 9 is preferably an electric gate valve or an electric ball valve, used to control the opening and closing of the discharge of the corresponding feed bin 5 and the discharge flow rate. A base plate 10 is fixedly connected to one side of the base 1. The base plate 10 is located directly below the rotation trajectory of one of the feed bins 5. A weighing sensor 11 is installed on the top of the base plate 10. The weighing sensor 11 is a precision electronic weighing module used to detect the weight of the feed falling into the container below. A connecting frame 14 is fixedly connected to one side of the bracket 4. The connecting frame 14 rotates synchronously with the bracket 4. A control panel 15 is installed on one side of the connecting frame 14. The control panel 15 is electrically or signal connected to the drive motor 3, the discharge valve 9, and the weighing sensor 11, serving as the central control unit of the entire device.

[0026] In this embodiment, specifically: a top cover 6 is hinged to the top of the feed silo 5, and a handle 7 is fixedly connected to the top of the top cover 6. The operator can open or close the top cover 6 by pulling the handle 7 to facilitate adding feed to the feed silo 5. Simultaneously, the top cover 6 remains closed during the feeding process to prevent debris from falling in and feed from splashing out. The feed silo 5 can be made of transparent material for easy observation of the feed level inside.

[0027] In this embodiment, specifically: an electric lifting platform 12 is fixedly connected to the top of the weighing sensor 11, and a positioning groove is provided on the top of the electric lifting platform 12. The electric lifting platform 12 is used to support the feeding container. When receiving feed, the operation of the electric lifting platform 12 brings the feeding cylinder 13 closer to the discharge port 8, ensuring that the material enters the feeding cylinder 13 smoothly. The positioning groove has a circular or square groove structure, which is used to quickly position and limit the feeding container, ensuring that the feeding container placed on the electric lifting platform 12 is in the same position each time, so that the discharge port 8 can be accurately aligned with the center of the opening of the feeding container, avoiding feed spillage.

[0028] In this embodiment, specifically: a feed cylinder 13 is provided on the top of the electric lifting platform 12. The feed cylinder 13 is detachably placed in the positioning slot of the electric lifting platform 12 as a feed container to receive feed falling from the discharge port 8. The feed cylinder 13 can be made of stainless steel for easy cleaning and replacement. Before each batching operation, the operator must first place the empty feed cylinder 13 on the electric lifting platform 12, and the system will automatically complete the tare and zeroing process before proceeding with subsequent batching operations. A display 16 is installed on the surface of the feed cylinder 13, which is used to indicate information such as the type of feed inside the cylinder.

[0029] In this embodiment, specifically: the control panel 15 includes a controller body 151, an audible and visual alarm 152, a display screen 153, and operation buttons 154. The controller body 151 is a programmable logic controller or an embedded microcontroller, integrating a data storage module and a processing module for storing set parameters, executing logical judgments, and outputting control commands. An audible and visual alarm 152 is mounted on the top of the controller body 151, including a buzzer and a warning light, capable of emitting both audible and flashing light alarm signals when the batching exceeds tolerance, to remind the operator to handle the situation promptly. A display screen 153 is mounted on the front surface of the controller body 151, which is an LCD touchscreen or digital display screen, used to display the current batching weight, target weight, tolerance range, batching progress, and alarm information in real time. Several operation buttons 154 are mounted on the front surface of the controller body 151, including numeric keys, confirmation keys, cancel keys, start keys, and stop keys, for the operator to input set parameters and send control commands.

[0030] In this embodiment, specifically: the controller body 151 is electrically connected to the audible and visual alarm 152 and the display screen 153. The controller body 151 controls the start and stop of the audible and visual alarm 152 according to the batching results, and at the same time sends real-time data and alarm information to the display screen 153 for visual display.

[0031] In this embodiment, specifically: the controller body 151 is signal-connected to the weighing sensor 11. The weighing sensor 11 transmits the collected analog weight signal to the built-in analog-to-digital converter module of the controller body 151 via a signal line. The controller body 151 amplifies, filters, and digitizes the received signal, converts it into an actual weight value, and compares it with a set value. The signal connection can be wired or wireless, with a wired connection preferred to ensure the stability and real-time performance of signal transmission.

[0032] In this embodiment, specifically: the controller body 151 is electrically connected to the drive motor 3 and the discharge valve 9. Based on the selection command input via the operation button 154 or the preset batching sequence, the controller body 151 outputs corresponding drive signals to control the start, stop, and rotation angle of the drive motor 3, thereby precisely rotating the designated feed bin 5 to the batching station. Simultaneously, the controller body 151 controls the opening and closing of the discharge valve 9 via electrical connection, and during the closing process, it can adjust the closing speed of the discharge valve 9 according to the real-time weight change trend to balance batching efficiency and accuracy.

[0033] In addition, the present invention also provides a control method for a rotary feed precision metering alarm dispensing device, comprising the following steps: Step S1: Set the target feed weight and tolerance range for each feed type using the control panel 15, and select the feed bin 5 to be dispensed. Before dispensing begins, the operator inputs the target feed weight value and allowable upper and lower deviation range for each feed bin 5 sequentially using the operation buttons 154, according to the feed formula, and selects the first feed bin 5 to be dispensed. The controller body 151 saves the above settings in its internal memory as the basis for subsequent dispensing control.

[0034] Step S2: Start the drive motor 3, which drives the support bracket 4 to rotate, aligning the discharge port 8 of the selected feed bin 5 directly above the feed cylinder 13 on the electric lifting platform 12. The controller body 151 calculates the rotation angle difference between the currently selected feed bin 5 and the feeding station based on the preset initial position angle codes of each feed bin 5, and controls the drive motor 3 to rotate according to the calculated angle. At the same time, the actual rotation angle is fed back using the encoder or Hall sensor built into the drive motor 3, forming a closed-loop control to ensure that the discharge port 8 is accurately positioned directly above the center of the feed cylinder 13.

[0035] Step S3: Open the discharge valve 9 on the discharge port 8 to allow the feed to fall into the feed cylinder 13. At the same time, the weighing sensor 11 collects the weight data of the falling feed in real time and transmits it to the controller body 151. After the discharge valve 9 is opened, the feed flows out from the bottom of the feed bin 5 and falls into the feed cylinder 13 under the action of gravity. The weighing sensor 11 continuously collects the total weight change of the feed cylinder 13 and the feed inside it at a sampling frequency of not less than 10 times per second, and uploads the weight data to the controller body 151 in real time. The controller body 151 also displays the real-time weight value on the display screen 153.

[0036] Step S4: The controller body 151 compares the real-time collected weight data with the set target feed weight. When the real-time weight reaches the target weight, the discharge valve 9 is closed, stopping the feed from the feed silo 5. During the discharge process, the controller body 151 continuously compares the difference between the real-time weight and the target weight. To ensure the feed dispensing speed while avoiding overshoot, when the real-time weight reaches 90% of the target weight, the controller body 151 can send a control signal to the discharge valve 9 to reduce the opening, reducing the feed flow rate to 30%-50% of the original flow rate, thereby reducing the impact of the falling inertia on the final weighing accuracy. When the real-time weight reaches 99% of the target weight, the controller body 151 closes the discharge valve 9 with a millisecond-level response speed, ensuring that the deviation between the actual falling weight and the target weight is controlled within the preset tolerance range.

[0037] Step S5: The controller body 151 determines whether the weight of the batch is within the set tolerance range. If it exceeds the tolerance range, the audible and visual alarm 152 is triggered to issue an alarm signal, and the out-of-tolerance information is displayed on the display screen 153. After the discharge valve 9 is completely closed, the controller body 151 waits for 1-2 seconds until the reading of the weighing sensor 11 stabilizes, then reads the final weight value, and compares this value with the target weight and the upper and lower tolerance limits. If the final weight is within the tolerance range, the batch is deemed qualified, the controller body 151 records the qualified data and automatically proceeds to the next step; if the final weight is lower than the lower tolerance limit or higher than the upper tolerance limit, it is deemed out of tolerance, the controller body 151 immediately sends a trigger signal to the audible and visual alarm 152, the audible and visual alarm 152 emits an intermittent buzzing sound and flashing red light, and at the same time displays the specific value and direction of the out-of-tolerance deviation in highlighted font on the display screen 153, prompting the operator to take corrective measures such as adding material or re-batching.

[0038] Step S6: Repeat steps S2 to S5 to complete the batching of the remaining feed bins 5 in sequence until all target feed batches are completed. When one type of feed is completed, the controller body 151 automatically or according to the operator's confirmation instruction selects the next feed bin 5 to be batched, and repeats the above-mentioned rotation positioning, discharging, weighing, comparison and alarm steps until all the raw materials to be prepared in all feed bins 5 are discharged according to the set weight, and all raw materials are collected in the feed cylinder 13, thus completing a complete batch batching operation.

[0039] When the feed hopper 13 is empty, the controller body 151 automatically reads the zero-point value of the weighing sensor 11 and subtracts this zero-point value during subsequent weighing processes. This step is preferably performed before or after step S1, but before the start of discharging. Specifically, after the operator places the empty feed hopper 13 into the positioning slot of the electric lifting platform 12, the controller body 151 automatically issues a zero-point calibration command. While the feed hopper 13 is stationary, the output signal of the weighing sensor 11 is continuously acquired 3-5 times, and the average value is stored in the internal register as the zero-point reference value. Throughout the subsequent batching process, the gross weight data acquired in real time by the weighing sensor 11 is automatically subtracted from this zero-point reference value to obtain the net weight of the pure feed, eliminating measurement errors caused by the weight of the feed hopper 13 and ensuring the accuracy and repeatability of the batching and weighing.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
