Description

Technical Field

[0001] This utility model relates to the field of powder dispensing technology, and in particular to a powder dispensing device. Background Technology

[0002] The utility model patent with application number CN202320337789.4 proposes a fixed-assembly weighing device for powder building materials. When weighing materials, the operator starts a rotating motor, which rotates the rotating shaft and rotating disk together. The receiving seat rotates along with the receiving box until the receiving box rotates under the discharging mechanism. The operator then stops the rotating motor and starts the control module to control the discharging mechanism to release the powder from the receiving box. This continues until the pressure sensor detects that the weight of the powder in the receiving box has reached the standard. The pressure sensor then sends a signal to the control module, which controls the discharging mechanism to stop discharging and controls the rotating motor to rotate so that the next receiving box can rotate under the discharging mechanism to receive the next material.

[0003] When the weight of the powder in the receiving hopper reaches the standard, the pressure sensor detects and sends a signal to the control module. The control module then controls the discharging mechanism to stop discharging. During this period, there is still some powder between the discharging mechanism and the receiving hopper that has not fallen, so the actual weight of the powder in the receiving hopper is greater than the measured value. To avoid a large deviation between the actual weight of the powder and the target weight, the discharging flow rate of the discharging mechanism should be set to a small value. At this time, it can be ensured that there is less powder between the discharging mechanism and the receiving hopper when discharging stops, which is negligible compared to the powder carried in the receiving hopper. However, limiting the discharging flow rate will affect the powder receiving efficiency.

[0004] In summary, existing powder feeding and weighing equipment cannot simultaneously guarantee high-precision weighing and high-efficiency material receiving. Utility Model Content

[0005] In view of this, it is necessary to provide a powder dispensing device to solve the problem that existing powder dispensing and weighing devices cannot simultaneously guarantee high-precision weighing and high-efficiency material receiving.

[0006] This utility model provides a powder dispensing device, including multiple hoppers, multiple valves, multiple weighing instruments, a bowl body, and a controller; the multiple hoppers are arranged sequentially along a transmission direction, each hopper having a discharge port at its bottom, and the diameter of the discharge ports of the multiple hoppers decreasing sequentially along the transmission direction; the multiple valves are respectively installed at the discharge ports of the multiple hoppers for opening and closing the corresponding discharge ports; the multiple weighing instruments are respectively located below the multiple hoppers; the bowl body has a holding cavity for receiving the powder discharged from the discharge ports of the multiple hoppers sequentially along the transmission direction; the controller is electrically connected to the multiple valves and the multiple weighing instruments, and the controller controls the operation of the valves above the weighing instruments based on the weighing data of the weighing instruments.

[0007] Furthermore, the silo includes a cylindrical silo body and a conical silo body. The top of the cylindrical silo body has a feed inlet, the bottom of the cylindrical silo body is connected to the larger diameter end of the conical silo body, and the tip of the bottom of the conical silo body has a discharge outlet.

[0008] Furthermore, it also includes multiple discharge pipes, all of which are vertically arranged, with the top ends of the multiple discharge pipes respectively connected to the discharge ports of the multiple hoppers, and the multiple valves respectively installed inside the multiple discharge pipes.

[0009] Furthermore, it also includes multiple lifting components, the output ends of which are respectively connected to multiple weighing instruments to drive the multiple weighing instruments to move in the vertical direction, so as to control the distance from the bowl placed on the weighing instrument to the discharge port.

[0010] Furthermore, it also includes a conveying assembly having a conveying end for connection with the bowl body, so that the bowl body can be moved sequentially to a plurality of the weighing instruments.

[0011] Furthermore, the conveying assembly includes a conveying bracket, a plurality of long rollers and a plurality of short rollers. The plurality of long rollers are sequentially arranged on the conveying bracket along the conveying direction, and a weighing space is formed between two adjacent long rollers. The plurality of short rollers are arranged on both sides of the weighing space and connected to the conveying bracket. The distance between two opposite short rollers is less than the width of the bowl. A plurality of weighing instruments are arranged in the weighing space, and each weighing instrument has a weighing end that can move in the vertical direction.

[0012] Furthermore, the conveying component is a robot, and the gripping end of the robot can be connected to the bowl.

[0013] Furthermore, the conveying component comprises a turntable and a clamping member. The clamping member is installed in a mounting hole on the turntable and is used to clamp or release the bowl. The turntable can be rotated to a position where the clamping member is located above any of the weighing instruments.

[0014] Furthermore, the controller has a signal receiving end and a signal output end. The signal receiving end is electrically connected to multiple weighing instruments, and the signal output end is electrically connected to multiple valves. When the signal receiving end receives the weight information detected by the weighing instrument, which is equal to a preset value, the signal output end controls the corresponding valve to close.

[0015] Furthermore, it also includes a feeding conveyor belt, the end of which is located above the inlet of the cylindrical silo body, for conveying the material into multiple cylindrical silos, and the multiple silos are arranged sequentially along the width direction of the feeding conveyor belt.

[0016] Compared with existing technologies, the first step involves placing the bowl under a hopper with a larger discharge port diameter. This hopper can efficiently add a large amount of powder into the bowl in a short time until the weight approaches the target value. At this point, the controller closes the valve. Then, the bowl is placed under a hopper with a smaller discharge port diameter. Due to the smaller powder flow rate, this hopper can accurately add powder until the weight reaches the target value. At this point, the controller closes the corresponding valve. When the valve is closed, because the discharge port flow rate is small, there is less powder that does not fall between the discharge port and the bowl. Therefore, the total weight of the powder in the bowl can be ignored, thus ensuring both high-precision weighing and high-efficiency material receiving. Attached Figure Description

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-3As shown, the present invention provides a powder dispensing device, comprising multiple hoppers 100, multiple valves 200, multiple weighing instruments 300, a bowl body 400, and a controller 500; the multiple hoppers 100 are arranged sequentially along a conveying direction, each hopper 100 having a discharge port 110 at its bottom, and the diameter of the discharge ports 110 of the multiple hoppers 100 decreasing sequentially along the conveying direction; multiple valves 200 are respectively installed at the discharge ports 110 of the multiple hoppers 100 for opening and closing the corresponding discharge ports 110; multiple weighing instruments 300 are respectively arranged below the multiple hoppers 100; the bowl body 400 has a holding cavity, which is used to sequentially receive the powder discharged from the discharge ports 110 of the multiple hoppers 100 along the conveying direction; the controller 500 is electrically connected to the multiple valves 200 and the multiple weighing instruments 300, and the controller 500 controls the operation of the valves 200 above the weighing instruments 300 according to the weighing data of the weighing instruments 300.

[0020] In practice, the bowl 400 is first placed below the hopper 100 with a larger diameter outlet 110. The hopper 100 can efficiently dispense a large amount of powder into the bowl 400 in a short time until the weight approaches the target value. At this point, the controller 500 controls the valve 200 to close. Then, the bowl 400 is placed below the hopper 100 with a smaller diameter outlet 110. Due to the smaller powder flow rate, the hopper 100 can accurately dispense the powder until the weight reaches the target value. At this point, the controller 500 controls the corresponding valve 200 to close. When the valve 200 is closed, due to the smaller flow rate at the outlet 110, there is less powder that does not fall between the outlet 110 and the bowl 400. Therefore, the total weight of the powder in the bowl 400 can be ignored, thus ensuring both high-precision weighing and high-efficiency material receiving.

[0021] In this embodiment, multiple hoppers 100 are arranged sequentially along a conveying direction, and each of the multiple hoppers 100 has a discharge port 110 at its bottom, with the diameter of the discharge port 110 of the multiple hoppers 100 decreasing sequentially along the conveying direction.

[0022] In one embodiment, the silo 100 includes a cylindrical silo body and a conical silo body. The top of the cylindrical silo body has a feed inlet, the bottom of the cylindrical silo body is connected to the larger diameter end of the conical silo body, and the tip of the bottom of the conical silo body has a discharge outlet 110.

[0023] In this embodiment, multiple discharge pipes are also included. All discharge pipes are vertically arranged, and the top ends of the multiple discharge pipes are respectively connected to the discharge ports 110 of multiple silos 100. Multiple valves 200 are respectively installed in the multiple discharge pipes.

[0024] During the powder feeding process, to prevent the distance between the discharge port 110 and the bowl 400 from being too large, which could cause powder to be thrown up and result in some powder not falling into the bowl 400 and polluting the environment, in one embodiment, multiple lifting components 310 are also included. The output ends of the multiple lifting components 310 are respectively connected to multiple weighing instruments 300 to drive the multiple weighing instruments 300 to move vertically, so as to control the distance between the bowl 400 placed on the weighing instrument 300 and the discharge port 110. It is understood that the lifting components 310 can be implemented using structures such as cylinders or hydraulic cylinders.

[0025] To facilitate the sequential movement of the bowl 400 onto multiple weighing instruments 300, this embodiment also includes a conveying assembly 600, which has a conveying end for connecting to the bowl 400 so that the bowl 400 can be sequentially moved onto multiple weighing instruments 300.

[0026] In one embodiment, the conveying assembly 600 includes a conveying bracket, a plurality of long rollers 610 and a plurality of short rollers 620. The plurality of long rollers 610 are sequentially arranged on the conveying bracket along the conveying direction, and a weighing space 630 is formed between two adjacent long rollers 610. The plurality of short rollers 620 are arranged on both sides of the weighing space 630 and connected to the conveying bracket. The distance between two opposite short rollers 620 is less than the width of the bowl 400. A plurality of weighing instruments 300 are arranged in the weighing space 630, and each weighing instrument 300 has a weighing end that can move in the vertical direction.

[0027] It is understandable that the weighing instrument 300 can be moved to a position below the conveying support by the lifting component 310, thereby avoiding interference between the weighing instrument 300 and the bowl 400, which would affect the movement of the bowl 400 along the conveying direction.

[0028] In another embodiment, the conveying component 600 is a robot, and the gripping end of the robot can be connected to the bowl 400.

[0029] In another embodiment, the conveying component 600 is a turntable and a clamping member. The clamping member is installed in a mounting hole on the turntable and is used to clamp or release the bowl 400. The turntable can be rotated to a position where the clamping member is above any weighing instrument 300.

[0030] The controller 500 in this embodiment has a signal receiving end and a signal output end. The signal receiving end is electrically connected to multiple weighing instruments 300, and the signal output end is electrically connected to multiple valves 200. When the signal receiving end receives weight information detected by the weighing instrument 300 that equals a preset value, the signal output end controls the corresponding valve 200 to close. It is understood that the controller 500 is a control structure that can be conceived by those skilled in the art, such as a microcontroller.

[0031] To supply materials to the multiple silos 100, this embodiment also includes a feeding conveyor belt 700. The end of the feeding conveyor belt 700 is located above the inlet of the cylindrical silo body, so as to transport the materials into the multiple cylindrical silos. The multiple silos 100 are arranged sequentially along the width direction of the feeding conveyor belt 700.

[0032] Compared with existing technologies: First, the bowl 400 is placed below the hopper 100 with a larger diameter outlet 110. The hopper 100 can efficiently add a large amount of powder into the bowl 400 in a short time until the weight approaches the target value. Then, the controller 500 controls the valve 200 to close. Next, the bowl 400 is placed below the hopper 100 with a smaller diameter outlet 110. Due to the smaller powder flow rate, the hopper 100 can accurately add powder until the weight reaches the target value. Then, the controller 500 controls the corresponding valve 200 to close. When the valve 200 is closed, due to the smaller flow rate at the outlet 110, there is less powder that does not fall between the outlet 110 and the bowl 400. Therefore, the total weight of the powder in the bowl 400 can be ignored, thus ensuring both high-precision weighing and high-efficiency material receiving.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
