Description

Technical Field

[0001] This utility model relates to the field of automatic weighing, and in particular to an automatic material weighing device. Background Technology

[0002] When weighing materials, it is necessary to manually place the materials onto the electronic scale and then weigh them. Based on this weight, adjustments are made to the weight of the materials on the electronic scale until the weight value reaches the standard range. Therefore, the weighing efficiency is low. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic material weighing device. The technical problem it solves is to automatically weigh materials and improve weighing efficiency.

[0004] To achieve the above objectives, the solution of this utility model is as follows: An automatic material weighing device includes, The receiving trough is used to receive materials. The bottom of the receiving trough has a receiving area and a discharge port. The receiving area is used to receive materials, and the discharge port is used for materials to fall out of the receiving trough. The spiral shaft is set in the receiving trough and is connected to the drive motor. The drive motor drives the spiral shaft to rotate in the receiving trough. The rotation of the spiral shaft can convey the material from the receiving area to the discharge port. An electronic scale, located below the discharge port, is used to catch materials falling from the discharge port. The electronic scale is connected to a drive motor via communication. The electronic scale can preset the material weighing value. When the weight of the material on the electronic scale reaches the preset material weighing value, the drive motor can stop driving the screw shaft.

[0005] Furthermore, the spiral shaft includes a spiral shaft body and spiral blades. The spiral shaft body is cylindrical, and the spiral blades extend spirally along the axial direction of the spiral shaft body on the side wall of the spiral shaft body. There are gaps between adjacent spiral blades, and the material falls into these gaps. When the drive motor drives the spiral shaft to rotate, the material is conveyed from the receiving area to the discharge port along the spiral blades.

[0006] Furthermore, the material is a magnet, and the spiral shaft is made of nylon.

[0007] Furthermore, it also includes a discharge trough, which has an inlet and an outlet. The inlet is used for feeding materials into the discharge trough, and the outlet is used for discharging materials from the discharge trough.

[0008] Furthermore, the top of the feeding trough is its opening, which is the inlet. Material is fed into the feeding trough from its opening. One side of the feeding trough is open, and the opening is its outlet. The bottom of the feeding trough slopes downward toward the outlet so that the material fed into the feeding trough slides toward the outlet. The opening of the receiving trough faces upward and is connected to the outlet of the feeding trough. The outlet of the feeding trough is located above the receiving area so that the receiving area receives the material that slides out of the feeding trough outlet.

[0009] Furthermore, it also includes a PLC unit. The electronic scale is connected to the drive motor via the PLC unit, and the electronic scale can preset the material weighing value through the PLC unit. The electronic scale can provide real-time feedback of the weight of the material on it to the PLC unit. When the weight of the material on the electronic scale reaches the preset material weighing value, the PLC unit controls the drive motor to stop driving the screw shaft, thereby stopping the material from being transported to the discharge port. Furthermore, it also includes a touch screen that connects to the PLC unit for inputting preset material weighing values.

[0010] Furthermore, it also includes a buzzer, which is connected to the PLC unit for communication and is used for alarm purposes.

[0011] Furthermore, it also includes a start button and a stop button, which are connected to the PLC unit. The start button is used to control the drive motor to start driving the screw shaft to rotate, and the stop button is used to control the drive motor to stop driving the screw shaft to rotate.

[0012] Furthermore, it also includes indicator lights, which are connected to the PLC unit. When the indicator lights are on, they indicate that the drive motor should stop driving the screw shaft to rotate.

[0013] After adopting the above solution, the beneficial effects of this utility model are as follows: This invention uses a drive motor to rotate a screw shaft, which can transport materials from the receiving area to the discharge port. After the materials fall from the discharge port onto the electronic scale below, they are weighed. When the weight of the materials on the electronic scale reaches the weighing value, the drive motor stops rotating the screw shaft, thereby stopping the transport of materials to the discharge port and the electronic scale. Therefore, this invention can automatically weigh materials and improves weighing efficiency. Furthermore, this invention utilizes a spiral conveyor to slowly deliver materials to the outlet, where they then fall onto the electronic scale. This achieves a slow discharge effect, allowing for precise control of the weight of the material falling onto the electronic scale. Attached Figure Description

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 2 As shown, this embodiment provides an automatic material weighing device, including a feeding trough 10, a receiving trough 20, a screw shaft 30, an electronic scale 40, and a PLC unit; The feeding trough 10 has an inlet 11 and an outlet 12. The inlet 11 is used for feeding materials into the feeding trough 10, and the outlet 12 is used for discharging materials from the feeding trough 10. The feeding trough 10 helps to concentrate the feeding of materials. Specifically, the top of the feeding trough 10 is its opening, and the opening of the feeding trough 10 is the inlet 11. Materials are fed into the feeding trough 10 from the opening. One side of the feeding trough 10 is open, and the opening of the feeding trough 10 is its outlet 12. The bottom of the feeding trough 10 slopes downward toward the outlet 12 so that the materials fed into the feeding trough 10 slide toward the outlet 12. The receiving trough 20 is used to receive materials. The bottom of the receiving trough 20 has a receiving area 22 and a discharge port 21. The receiving area 22 is used to receive materials, and the discharge port 21 is used for materials to fall out of the receiving trough 20. Specifically, the opening of the receiving trough 20 faces upward, and the opening of the receiving trough 20 is connected to the outlet 12 of the discharge trough 10. The outlet 12 of the discharge trough 10 is located above the receiving area 22 so that the receiving area 22 can receive materials that slide out from the outlet 12 of the discharge trough 10. Specifically, the discharge port 21 of the receiving trough 20 and the outlet 12 of the discharge trough 10 are staggered, and the receiving trough 20 is fixed at the outlet 12 of the discharge trough 10.

[0018] A spiral shaft 30 is disposed in a receiving trough 20 and is connected to a drive motor 33. The drive motor 33 drives the spiral shaft 30 to rotate within the receiving trough 20. The rotation of the spiral shaft 30 can spirally convey the material from the receiving area 22 to the discharge port 21, and the material falls out of the receiving trough 20 from the discharge port 21. Specifically, the spiral shaft 30 includes a spiral shaft body 31 and spiral blades 32. The spiral shaft body 31 is cylindrical, and the spiral blades 32 extend spirally along the axial direction of the spiral shaft body 31 on the side wall of the spiral shaft body 31. There is a gap between adjacent spiral blades 32, and the material falls into this gap. When the drive motor 33 drives the spiral shaft 30 to rotate, the material is conveyed from the receiving area 22 to the discharge port 21 along the spiral blades 32.

[0019] An electronic scale 40 is located below the discharge port 21 to receive materials falling from the discharge port 21. The electronic scale 40 is connected to the drive motor 33 via communication, and the electronic scale 40 can preset the material weighing value. When the weight of the material on the electronic scale 40 reaches the preset material weighing value, the drive motor 33 can stop driving the screw shaft 30.

[0020] Specifically, the electronic scale 40 is connected to the drive motor via a PLC unit, and the electronic scale 40 presets the material weighing value through the PLC unit. The electronic scale 40 can provide real-time feedback on the weight of the material on it to the PLC unit. When the weight of the material on the electronic scale 40 reaches the preset material weighing value, the PLC unit controls the drive motor 33 to stop driving the screw shaft 30, thereby stopping the material from being transported to the discharge port 21. Preferably, the material is a magnet, and the spiral shaft 30 is made of nylon.

[0021] Furthermore, it also includes a buzzer 50, which is connected to the PLC unit for communication. The buzzer 50 is used for alarms. When the electronic scale 40 fails to reach the preset material weighing value within a certain period of time, the buzzer 50 will sound an alarm. This period of time is set according to the actual experience of the staff.

[0022] Furthermore, it also includes a touch screen 60, which is connected to the PLC unit for inputting preset material weighing values.

[0023] Furthermore, it also includes a start button 70 and a stop button 80, which are communicatively connected to the PLC unit. The start button 70 is used to control the drive motor 33 to start driving the spiral shaft 30 to rotate, and the stop button 80 is used to control the drive motor 33 to stop driving the spiral shaft 30 to rotate.

[0024] Furthermore, it also includes an indicator light 90, which is connected to the PLC unit. When the indicator light 90 is lit, it indicates that the drive motor 33 should stop driving the screw shaft 30 to rotate.

[0025] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0026] The above description is only a preferred embodiment of this utility model and is not a limitation on the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
