Description

Technical Field

[0001] The present application relates to the technical field of material conveyors, and in particular to an integrated weighing and feeding device. Background Art

[0002] Material conveyors are mainly used to convey powdered, granular and block materials. The materials are poured into the hopper and then conveyed by the screw. Existing material conveyors include small hopper conveyors disclosed in announcement numbers: CN214526319U and CN209467714U. Such material conveyors can only take on dozens of kilograms of materials at a time, while the mixer that feeds the material conveyor is usually loaded with more than 200 kilograms of materials. This results in a long discharge time for the mixer, and the mixer cannot quickly discharge and continue production, affecting the production efficiency of the mixer. In order to reduce the impact on the production efficiency of the mixer, there are large hopper conveyors disclosed in announcement numbers: CN211393121U and CN202213726U. Although such material conveyors can take on more materials each time, the large hopper cannot be directly replaced by a loss-in-weight scale like the small hopper to receive and weigh the materials. Therefore, the existing material conveyor does not have both large capacity and load-bearing functions. During production, all materials from the mixer need to be discharged to the weighing equipment for weighing, and then the materials are transferred from the weighing equipment to a large-capacity hopper. The operation is cumbersome and the production efficiency is low. Utility Model Content

[0003] In order to enable the material machine to accommodate more materials at one time and have a weighing function, thereby facilitating material weighing and transportation and improving production efficiency, the present application provides an integrated weighing and feeding device.

[0004] The present application provides an integrated weighing and feeding device that adopts the following technical solution:

[0005] A weighing and feeding integrated device comprises a silo, a support frame and a conveying assembly, wherein a plurality of gravity sensors are arranged on the support frame, the plurality of gravity sensors jointly support the silo and are connected to the silo, the feed end of the conveying assembly is connected to the discharge end of the silo, and the conveying assembly is provided with a driving assembly for driving its operation.

[0006] By adopting the above technical solution, the support frame cooperates with several gravity sensors to fix the silo. Compared with the traditional method of using a fixed frame to support the large hopper, the silo is supported by a gravity sensor. After the material enters the silo, the weight of the material can be obtained by adding and subtracting the weight of the silo, the drive component and the transmission component from the data measured by several gravity sensors, thereby realizing the load-bearing of the material, and multiple gravity sensors are used for support to balance the force of the silo.

[0007] When multiple gravity sensors work at the same time, the weight values ​​measured by each of them will be added together to obtain the total weight of the material in the hopper. This method can ensure the accuracy of the measurement because the readings of all gravity sensors are taken into account and reflect the actual weight distribution of the entire hopper;

[0008] Moreover, the redundant design of multiple gravity sensors can improve the reliability and fault tolerance of load-bearing measurement. When some gravity sensors fail, the system can perform compensation calculations based on the readings of the remaining gravity sensors and the known positions of the gravity sensors, and continue to provide relatively accurate weight data.

[0009] Therefore, compared with using a loss-in-weight scale in conjunction with an extrusion screw for transportation, this design can accommodate more materials at one time, saving the loading time of the mixer. The quality of the material can be obtained in real time after all the materials are poured into the silo. At the same time, the flow rate of the material can be detected during the material transfer process, and the load-bearing accuracy is high, realizing integrated loading and load-bearing, facilitating material weighing and transportation, and improving production efficiency overall.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] The embodiment of the present application discloses an integrated weighing and feeding device.

[0039] like Figure 1 and Figure 2 The integrated weighing and feeding device includes a silo 1, a support frame 2 and a conveying assembly 3. The support frame 2 is a cube frame. Self-locking rollers 21 are installed at the bottom of the four vertical poles of the support frame 2. Three support seats 22 are welded on the top of the support frame 2. Gravity sensors 4 are bolted on the three support seats 22. In the embodiment of the present application, the gravity sensor 4 is a bellows load-bearing sensor.

[0040] The silo 1 is funnel-shaped. The silo 1 in the embodiment of the present application can accommodate 400 kilograms of materials. The silo 1 is welded with three connecting plates 11 at equal intervals along its circumference. Each connecting plate 11 is welded with a support block 12. Each support block 12 is bolted with a force transmission column 13. The force transmission column 13 is vertically arranged downward, and the force transmission column 13 corresponds to the gravity sensor 4 one by one and is bolted. The top of the silo 1 is provided with a material transmission port 14, an auxiliary operation port 15 and an inspection and maintenance port 16. The material transmission port 14 and the auxiliary operation port 15 are both circular ports, and the inspection and maintenance port 16 is a semicircular port. The top of the silo 1 is hinged with a cover 17 for closing the inspection and maintenance port 16. The bottom of the silo 1 extends into the support frame 2, and the discharge end at the bottom of the silo 1 is connected to the conveying component 3. The conveying component 3 is provided with a driving component 5 for driving it to transport materials.

[0041] When the material is being transferred, the material in the mixer is poured into the silo 1 at one time through the material transfer port 14. After the material enters the silo 1, the weight of the silo 1, the driving component 5 and the conveying component 3 are subtracted from the data measured by the gravity sensors 4 to obtain the mass of the material, thereby achieving the load-bearing of the material, and the multiple gravity sensors 4 provide support to balance the force of the silo 1.

[0042] When multiple gravity sensors 4 work simultaneously, the weight values ​​measured by each of them are added together to obtain the total weight of the material in the silo 1. This method can ensure the accuracy of the measurement because the readings of all gravity sensors 4 are taken into account and the actual weight distribution of the entire silo 1 is reflected;

[0043] Moreover, the redundant design of multiple gravity sensors 4 can improve the reliability and fault tolerance of load-bearing measurement. When some gravity sensors 4 fail, the system can perform compensation calculations based on the readings of the remaining gravity sensors 4 and the known positions of the gravity sensors 4, and continue to provide relatively accurate weight data;

[0044] After determining the total mass of the material, the drive assembly 5 is started, and the drive assembly 5 drives the conveying assembly 3 to transport the material. During the transportation process, the auxiliary operation port 15 is used for ventilation or feeding, balancing the pressure inside and outside the silo 1 to prevent negative pressure or positive pressure from affecting the flow of materials. Sometimes it can also be used to add auxiliary materials or additives for mixing during the production process. At the same time, according to the data changes provided by the gravity sensor 4, the flow rate of the material can be monitored in real time to facilitate timely adjustments;

[0045] Therefore, compared with using a loss-in-weight scale in conjunction with an extrusion screw for transportation, this design can accommodate more materials at one time, saving the loading time of the mixer, and the quality of the materials can be obtained in real time after all the materials are poured into the silo 1. At the same time, the flow rate of the materials can be detected during the material transfer process, and the load-bearing accuracy is high, realizing an integrated loading and load-bearing type, facilitating material weighing and transportation, and improving production efficiency as a whole.

[0046] like Figure 1 , Figure 3 and Figure 4 The conveying assembly 3 includes a material receiving pipe 31 and a conveying screw 32. The material receiving pipe 31 includes a material receiving shell 311. The top of the material receiving shell 311 is set to be open, and the longitudinal section of the material receiving shell 311 is concave. The conveying screw 32 is rotatably connected in the material receiving shell 311. The bottom wall of the material receiving shell 311 is set to be an arc wall adapted to the conveying screw 32. A connecting rod 33 is welded to the top of the material receiving shell 311. The connecting rod 33 is located in the middle of the material receiving shell 311. The connecting rod 33 is bolted to a diagonal rod 34, and the diagonal rod 34 is bolted to the side wall of the silo 1. The top of the receiving shell 311 is covered with two upper covers 312, which cooperate with the connecting rod 33 to close the opening of the receiving shell 311. The side wall of the receiving shell 311 is equidistantly provided with toggle clamps 313 for fixing the upper covers 312 along its length direction. A feed pipe 35 is welded to one end of the upper cover 312 near the bottom of the hopper. The feed pipe 35 is connected to the receiving shell 311, and the angle between the feed pipe 35 and the upper cover 312 facing the connecting rod 33 is an acute angle. A first flange 18 is welded to the discharge end at the bottom of the silo 1, and a second flange 351 is welded to the feed end of the feed pipe 35. The first flange 18 and the second flange 351 are buckled and bolted.

[0047] A mounting plate 36 is welded to one end of the bottom of the material receiving shell 311 close to the silo 1, and the driving assembly 5 includes a driving motor 51, and the driving motor 51 is connected to a reducer 52, and the reducer 52 is located on one side of the material receiving shell 311 and fixed on the mounting plate 36, and the reducer 52 is coaxially connected to a first sprocket 53, and the conveying screw 32 is coaxially connected to a second sprocket 54, and the first sprocket 53 and the second sprocket 54 are driven by a chain 55.

[0048] The material is discharged from the silo 1 into the feed pipe 35, and then discharged into the material receiving shell 311 by the feed pipe 35. The driving motor 51 drives the reducer 52 to operate, and the reducer 52 drives the first sprocket 53 to rotate. The first sprocket 53 drives the second sprocket 54 to rotate through the chain 55, and the second sprocket 54 drives the conveying screw 32 to rotate. The conveying screw 32 transports the material to the discharge end of the material receiving shell 311 for discharge. After the material feeding is completed, the toggle clamp buckle 313 is opened to separate the upper cover 312 from the material receiving shell 311, so as to facilitate the cleaning and maintenance of the conveying screw 32.

[0049] The implementation principle of the embodiment of the present application is as follows: the support frame 2 cooperates with a plurality of gravity sensors 4 to fix the silo 1, and the gravity sensors 4 are used to support the silo 1. After the material enters the silo 1, the data measured by the plurality of gravity sensors 4 are added together and the weight of the silo 1, the drive assembly 5 and the transmission assembly are subtracted to obtain the mass of the material, thereby realizing the load-bearing of the material, and multiple gravity sensors 4 are used for support to balance the force on the silo 1.

[0050] Compared with using a loss-in-weight scale in conjunction with an extrusion screw for transportation, this design can accommodate more materials at one time, saving the loading time of the mixer. The quality of the materials can be obtained in real time after all the materials are poured into the silo 1. At the same time, the flow rate of the materials can be detected during the material transfer process, and the load-bearing accuracy is high, realizing an integrated loading and load-bearing system, which is convenient for material weighing and transportation, and improves production efficiency as a whole.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
