Description

Technical Field

[0001] This utility model relates to the field of feed packaging equipment technology, and in particular to a quantitative packaging machine for feed production. Background Technology

[0002] Quantitative dispensing machines are widely used in feed production. They can fill bags with produced feed according to a set weight or volume, and then seal and transport them. Quantitative dispensing machines achieve automated feed dispensing and improve the level of automation in production; however, there is still room for improvement in the dispensing accuracy of existing equipment.

[0003] In the prior art, the invention patent with authorization announcement number CN112777010B discloses a quantitative dispensing device for pig feed processing. This quantitative dispensing device completes the quantitative loading of feed by filling the feed in the feeding box with the quantitative regulating tube and the quantitative regulating cavity, and then controlling the quantitative drying component to block the feeding hole. Then, the solenoid valve on the conical discharge pipe is opened to dispense the quantitative feed.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: the patented technology cannot be continuously packaged, resulting in low work efficiency; the weight is limited by quantitative adjustment tubes and quantitative adjustment chambers, which is not very accurate. In order to avoid insufficient weight, the weight is usually set to exceed a certain proportion, which leads to increased costs. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a quantitative dispensing machine for feed production. This machine can achieve high-precision continuous dispensing, reducing costs and improving efficiency.

[0006] The technical solution to the technical problem solved by this utility model is as follows: An embodiment of this utility model provides a quantitative dispensing machine for feed production, including a storage hopper and a frame. The storage hopper is funnel-shaped and installed on the top of the frame. Two discharge ports are provided on the bottom surface of the storage hopper, and a sealing device is provided at each discharge port. The sealing device includes a cylinder, a sealing plate, a guide rail, a sealing plate, and a cylinder. One guide rail is provided on each side of the discharge port, and a guide groove is provided on the guide rail. The sealing plate is installed in the guide groove on the guide rail. Cylinder 1 is fixed to the frame. The telescopic rod of cylinder 1 is connected to sealing plate 1. Cylinder 2 is fixed to sealing plate 1. Sealing plate 1 has a discharge port 2. Sealing plate 2 fits snugly against sealing plate 1 and is mounted on the telescopic rod of cylinder 2. When the telescopic rod of cylinder 2 extends, sealing plate 2 closes discharge port 2; when the telescopic rod of cylinder 2 retracts, discharge port 2 is exposed. A metering box is located below each discharge port. The top and bottom of the metering box are open. A feeding mechanism is located at the bottom opening of the metering box. A loading hopper is also located below both metering boxes. The loading hopper releases a fixed amount of feed into the metering box. The metering box releases feed into the loading hopper via the feeding mechanism. Packaging bags are placed at the bottom of the loading hopper for further packaging.

[0007] As an optimization, the quantitative dispensing machine also includes a weight sensor, which is fixed on the frame and the quantitative box is mounted on the weight sensor.

[0008] As an optimization, the feeding mechanism includes a sealing plate three, a guide rail three, and a cylinder three. One guide rail three is installed on each side of the opening on the bottom surface of the metering box, and each guide rail three has a guide groove. The sealing plate three is installed in the guide groove on the guide rail three. The cylinder three is installed on the metering box, and its extension rod is connected to the sealing plate three. When the extension rod of the cylinder three is fully extended, the sealing plate three completely closes the opening on the bottom surface of the metering box; when the extension rod of the cylinder three is fully retracted, the opening on the bottom surface of the metering box is fully exposed, and the metering box feeds material.

[0009] As an optimization, the hopper is funnel-shaped with openings on both the top and bottom surfaces. The hopper is fixed to the frame. At the bottom opening of the hopper, there are clamps, a baffle, and a cylinder. Two clamps are symmetrically arranged on the left and right sides, each U-shaped with its opening facing the other. The upper outer edge of the clamps is hinged to the hopper. The cylinder body and telescopic rod of the cylinder are hinged to the two clamps respectively. The baffle is fixed to the hopper and is trapezoidal, wider at the top and narrower at the bottom, positioned between the two clamps. When the telescopic rod of the cylinder extends, the two clamps move away, exposing the bottom opening of the hopper for bagging. When the telescopic rod retracts, the two clamps move closer until they are flush with the side of the baffle, closing the bottom opening of the hopper.

[0010] As an optimization, a pad is also provided on the outer side of the clamping plate, and the pad is installed on the frame. When the telescopic rod of cylinder four extends, the left and right clamping plates move away from each other and fit against the outer pad. The pad is made of rubber, which can play a buffering role, reduce collisions, and improve the service life of the equipment.

[0011] As an optimization, the quantitative dispensing machine also includes a controller, an air source, solenoid valves, and control buttons. Cylinders 1, 2, 3, and 4 are each connected to the air source via a solenoid valve. The control ports of the four solenoid valves are connected to the controller. The signal port of the weight sensor is connected to the controller. The control buttons are connected to the controller and include a start button and a discharge button. When not in operation, the equipment and air source are powered off. When in operation, the equipment and air source are powered on, and the controller is in standby mode. Pressing the start button starts the controller to control cylinders 1, 2, 3, and 4 to open the bottom opening of the loading hopper and release a fixed amount of feed from the two quantitative boxes. After pressing the discharge button, the controller controls the telescopic rod of cylinder 3 at the bottom of one of the quantitative boxes to retract, releasing feed into the material bag at the bottom of the loading hopper. A release time is set, and after the time is reached, all the feed in the quantitative box is released. Then, the controller controls the telescopic rod of cylinder 3 to extend, closing the bottom opening of the quantitative box and opening the sealing device at the top of the quantitative box to release a fixed amount of feed. Pressing the discharge button again will discharge material into another quantitative box, and this process will continue until the dispensing is complete and the power is disconnected.

[0012] As an optimization, the solenoid valve is a two-position five-way solenoid valve, and the controller is a PLC.

[0013] The effects provided in the description of this utility model are merely those of the embodiments, and not all the effects of this utility model. The above technical solutions have the following advantages or beneficial effects:

[0014] 1. By setting two discharge ports and two metering boxes, a certain amount of material is being discharged and bagged into one metering box while the other metering box is storing material, enabling continuous packaging, reducing costs and improving efficiency. When the telescopic rod of cylinder one is fully extended, sealing plate one can close the discharge port; when the telescopic rod of cylinder one is fully retracted, the discharge port is fully exposed. A fixed amount of feed can be released into the metering box through the sealing device: first, the telescopic rod of cylinder one is controlled to retract, and the discharge port is exposed for discharging. When the set weight is approached, the telescopic rod of cylinder one is controlled to extend and close the discharge port; then, the telescopic rod of cylinder two is controlled to retract, and discharge port two is exposed for discharging at a small flow rate until the set weight is reached. By setting discharge port two, cylinder two, and sealing plate two, small flow rate discharging can be achieved, realizing high-precision control of the discharging weight.

[0015] 2. By installing a sealing mechanism at the bottom opening of the hopper, which includes a clamping plate, a baffle, and a cylinder, the bottom opening of the hopper is closed when the equipment is not in operation, and opened when the equipment is dispensing, thus preventing foreign objects from entering and improving food safety.

Detailed Implementation

[0026] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] Figures 1 to 10 illustrate one embodiment of this utility model. As shown in Figure 1, a quantitative dispensing machine for feed production includes a storage hopper 1 and a frame 4. The storage hopper 1 is funnel-shaped and installed on the top of the frame 4. Two discharge ports 101 are provided on the bottom surface of the storage hopper 1, and a sealing device is provided at each discharge port 101, as shown in Figure 6. The sealing device includes a cylinder 5, a sealing plate 6, a guide rail 7, a sealing plate 8, and a cylinder 9. One guide rail 7 is provided on each side of the discharge port 101, and a guide groove is provided on the guide rail 7. The sealing plate 6 is installed in the guide groove on the guide rail 7. The cylinder 5 is fixed to the frame 4, and the telescopic rod of the cylinder 5 is connected to the sealing plate 6. The cylinder 9 is fixed to the sealing plate 6. A discharge port 61 is provided on the sealing plate 6, and the sealing plate 8 fits against the sealing plate 6. Installed on the telescopic rod of cylinder 29, when the telescopic rod of cylinder 29 extends, the sealing plate 28 closes the discharge port 261, and when the telescopic rod of cylinder 29 retracts, the discharge port 261 is exposed; a metering box 2 is set below each discharge port 101, the top and bottom surfaces of the metering box 2 are open, a feeding mechanism is set at the bottom opening of the metering box 2, and a loading hopper 3 is also set below the two metering boxes 2.

[0028] As shown in Figures 7 and 8, the quantitative dispensing machine also includes a weight sensor 13, which is fixed on the frame 4, and the quantitative box 2 is installed on the weight sensor 13.

[0029] The feeding mechanism includes a sealing plate 310, a guide rail 311, and a cylinder 312. One guide rail 311 is installed on each side of the opening on the bottom surface of the metering box 2. The guide rail 311 has guide grooves. The sealing plate 310 is installed in the guide grooves on the guide rail 311. The cylinder 312 is installed on the metering box 2, and its extension rod is connected to the sealing plate 310. When the extension rod of the cylinder 312 is fully extended, the sealing plate 310 completely closes the opening on the bottom surface of the metering box 2; when the extension rod of the cylinder 312 is fully retracted, the opening on the bottom surface of the metering box 2 is fully exposed, and the metering box 2 begins feeding.

[0030] As shown in Figure 9, the hopper 3 is a funnel shape with openings on both the top and bottom surfaces. The hopper 3 is fixed on the frame 4. The bottom opening of the hopper 3 is provided with clamping plates 14, baffles 15, and cylinders 17. Two clamping plates 14 are symmetrically arranged on the left and right sides. The clamping plates 14 are U-shaped, and the U-shaped openings of the two clamping plates 14 are arranged opposite each other. The upper outer side of the clamping plates 14 is hinged to the hopper 3. The cylinder body and the telescopic rod of the cylinder 17 are respectively hinged to the two clamping plates 14. The baffle 15 is fixed on the hopper 3. The baffle 15 is a trapezoid with a wider top and a narrower bottom, and the baffle 15 is arranged between the two clamping plates 14. When the telescopic rod of cylinder 17 extends, the left and right clamping plates 14 move away, exposing the bottom opening of the hopper 3 for bagging. When the telescopic rod of cylinder 17 retracts, the left and right clamping plates 14 move closer until they are flush with the side of the baffle 15, sealing the bottom opening of the hopper 3. By setting a sealing mechanism at the bottom opening of the hopper 3, which includes clamping plates 14, baffle 15, and cylinder 17, the bottom opening of the hopper 3 is closed when the equipment is not in operation, and opened when the equipment is dispensing, preventing foreign objects from entering and improving food safety. A pad 16 is also provided on the outside of the clamping plates 14, and the pad 16 is installed on the frame 4. When the telescopic rod of cylinder 4 17 extends, the left and right clamps 14 move away and fit against the outer pad 16 respectively. The pad 16 is made of rubber, which can play a buffering role, reduce collisions, and improve the service life of the equipment.

[0031] As shown in Figure 10, the quantitative dispensing machine also includes a controller, an air source, solenoid valves, and control buttons. Cylinder 1 (5), Cylinder 2 (9), Cylinder 3 (12), and Cylinder 4 (17) are each connected to the air source via a solenoid valve. The control ports of the four solenoid valves are connected to the controller. The signal port of the weight sensor 13 is connected to the controller. The control buttons are connected to the controller and include a start button and a discharge button. The solenoid valves are two-position five-way solenoid valves, and the controller is a PLC. When not in operation, the power to the equipment and the air source is cut off. During operation, power is supplied to the equipment and air source, and the controller is in standby mode. Pressing the start button activates cylinders 5, 9, 12, and 17, opening the bottom opening of the loading hopper 3 and releasing a fixed amount of feed from the two metering boxes 2. Pressing the discharge button retracts the telescopic rod of cylinder 12 at the bottom of one metering box 2, releasing feed into the bag at the bottom of the loading hopper 3. A release time is set; after the time is up, all feed in the metering box 2 is released. Then, the telescopic rod of cylinder 12 extends, closing the bottom opening of the metering box 2 and opening the sealing device at the top of that metering box 2 to release a fixed amount of feed. Pressing the discharge button again releases feed from the other metering box 2, repeating the cycle until the dispensing is complete, at which point the power is disconnected.

[0032] The storage hopper 1 releases a fixed amount of feed into the metering box 2. The metering box 2 releases the feed into the loading hopper 3 via a dispensing mechanism. Packaging bags are placed at the bottom of the loading hopper 3 for further packaging. By setting two discharge ports 101 and two metering boxes 2, while dispensing and bagging a certain amount of feed into one metering box 2, the other metering box 2 is used for storage, enabling continuous packaging, reducing costs and improving efficiency. When the telescopic rod of cylinder 5 is fully extended, the sealing plate 6 can close the discharge port 101; when the telescopic rod of cylinder 5 is fully retracted, the discharge port 101 is fully exposed. A fixed amount of feed can be released into the metering box 2 via a sealing device: first, the telescopic rod of cylinder 5 is retracted, exposing the discharge port 101 for feeding; when the set weight is approached, the telescopic rod of cylinder 5 is extended to close the discharge port 101; then, the telescopic rod of cylinder 9 is retracted, exposing the discharge port 61 for feeding in a small flow rate until the set weight is reached. By setting the discharge port 61, cylinder 9, and sealing plate 8, a small flow rate of feed can be fed, achieving high-precision control of the feeding weight.
