Description

Technical Field

[0001] This utility model relates to the field of electrolytic silver powder conveying technology, and in particular to a conveyor for conveying electrolytic silver powder. Background Technology

[0002] Electrolytic silver powder is a type of silver powder prepared by electrochemical reduction. By adding a reducing agent to an electrolyte containing silver cations and heating the reducing agent with an electric current, a voltammetric electrochemical reaction occurs, resulting in metallic silver ions that are deposited on the electrode, ultimately yielding silver powder. In the production and processing of electrolytic silver powder, the application of conveyors plays a crucial role.

[0003] Traditional conveyors have several problems when transporting electrolytic silver powder. For example, poor sealing performance can easily lead to contamination or leakage of the silver powder during transport, affecting product quality. Furthermore, traditional conveyors lack precise weighing and destatication functions, making it impossible to accurately measure and treat the transported silver powder. This limits their application in electrolytic silver powder production. Therefore, we propose a new conveyor for transporting electrolytic silver powder to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor sealing performance of traditional conveyors which easily leads to contamination or leakage of electrolytic silver powder during transportation, and the inability to accurately measure and electrostatically treat the transported electrolytic silver powder. Therefore, this invention proposes a conveyor for transporting electrolytic silver powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveyor for conveying electrolytic silver powder includes a feeding cylinder, both ends of which are sealed. An inlet and an outlet are respectively located at the top and bottom of the feeding cylinder, respectively, and are positioned at opposite ends. A feeding hopper connected to the inlet is fixedly installed at the inlet of the feeding cylinder, and a discharge cylinder connected to the outlet is fixedly installed at the outlet of the feeding cylinder. A support frame is fixedly installed at the bottom of the feeding cylinder, and a PLC control box is fixedly installed on one side of the support frame. A PLC controller is installed inside the PLC control box. A screw rod is rotatably connected inside the feeding cylinder. The conveyor also includes:

[0007] The drive assembly is located at one end of the feeding cylinder near the inlet and is used to drive the screw to rotate to achieve material flow.

[0008] Weighing component, which is located at the end of the feeding cylinder near the discharge port, is used to weigh the material being conveyed out of the feeding cylinder;

[0009] The static eliminator is installed on the feeding cylinder and is used to remove static electricity from the materials being conveyed out of the feeding cylinder.

[0010] In one possible design, the drive assembly includes a motor gearbox, which is fixedly mounted at one end of the feeding cylinder. One end of the screw rod passes through the feeding cylinder and is fixedly connected to the output shaft of the motor gearbox. A first motor is fixedly mounted on one side of the motor gearbox, and the output end of the first motor is fixedly connected to the input shaft of the motor gearbox. The first motor is electrically connected to a PLC controller.

[0011] In one possible design, the weighing assembly includes two L-shaped fixing frames, which are symmetrically fixed on the outer wall of the feeding cylinder and located on both sides of the discharge port. Support blocks are fixed on the side of the two L-shaped fixing frames that are close to each other. Weighing sensors electrically connected to the PLC controller are fixed on the two support blocks. The same weighing hopper is set on the two weighing sensors, and the weighing hopper is located directly below the feeding cylinder.

[0012] In one possible design, a baffle for sealing is provided at the top opening of the weighing hopper, the baffle has a through hole, the bottom of the discharge cylinder passes through the through hole and extends into the interior of the weighing hopper, and a discharge cylinder is provided at the bottom of the weighing hopper, and the discharge cylinder is connected to the interior of the weighing hopper.

[0013] In one possible design, a flap is rotatably connected inside the discharge cylinder via a shaft, and the diameter of the flap is the same as the inner diameter of the discharge cylinder. A second motor is fixedly mounted on the outer wall of the discharge cylinder via a connecting block. The output end of the second motor is fixedly connected to the shaft, and the second motor is electrically connected to a PLC controller.

[0014] In one possible design, the antistatic component includes a fixing plate with a circular hole of the same diameter as the discharge cylinder. The discharge cylinder is inserted into the circular hole and fixedly connected to the fixing plate. A connecting plate is fixedly connected to one side of the fixing plate. Multiple antistatic bars are evenly spaced on the connecting plate, with one end of each bar inserted into one side of the fixing plate and extending to the other side.

[0015] In this application, electrolytic silver powder enters the feeding cylinder through the feeding hopper, and is rotated by the screw rod under the drive of the drive assembly (motor reducer and first motor), which transports the electrolytic silver powder from one end of the feeding cylinder to the other end. The feeding cylinder has a sealed design at both ends, which effectively prevents leakage and contamination of materials during the conveying process.

[0016] When the electrolytic silver powder is conveyed to the discharge port of the feeding cylinder, it falls into the weighing hopper. At this time, the flap inside the discharge cylinder, which is connected to the bottom of the weighing hopper, seals the discharge cylinder under the drive of the second motor to prevent the electrolytic silver powder from being discharged before the weighing is completed. The weighing sensor in the weighing assembly continuously transmits the weight information to the PLC controller in the PLC control box. After the required measurement is reached, the PLC controller controls the first motor to stop working, thereby stopping the conveying of electrolytic silver powder.

[0017] During the process of electrolytic silver powder falling from the discharge port of the feeding cylinder into the weighing hopper, the electrolytic silver powder will pass through the electrostatic component in the discharge cylinder. The electrostatic bar in the electrostatic component neutralizes the static electricity by generating a charge opposite to the surface charge of the electrolytic silver powder, thereby achieving the effect of removing static electricity and effectively avoiding the threat to production equipment and personnel safety caused by electrostatic discharge.

[0018] Finally, the flap inside the discharge cylinder can be flipped under the drive of the second motor, and the electrolytic silver powder that has been weighed and destaticated is discharged through the discharge cylinder to enter the next process. Beneficial effects

[0019] In this utility model, the conveyor for conveying electrolytic silver powder effectively prevents leakage and contamination of electrolytic silver powder during the conveying process by sealing both ends of the feeding cylinder and designing a screw rod, thereby improving the purity and quality of the product and ensuring continuous and uniform conveying of electrolytic silver powder.

[0020] In this utility model, the conveyor for conveying electrolytic silver powder can weigh the conveyed electrolytic silver powder in real time through the setting of the weighing component, providing accurate data support for metering and batching in the production process.

[0021] In this utility model, the conveyor for conveying electrolytic silver powder has an electrostatic component that effectively removes static electricity from the electrolytic silver powder, avoiding the threat to production equipment and personnel safety posed by electrostatic discharge and other problems.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1: Refer to Figure 1-5 A conveyor includes a feeding cylinder 1, which is sealed at both ends. An inlet and an outlet are respectively located at the top and bottom of the feeding cylinder 1, respectively, and are situated at opposite ends. A feeding hopper 2, connected to the inlet, is fixedly installed at the inlet of the feeding cylinder 1. A discharge cylinder 3, connected to the discharge outlet, is fixedly installed at the outlet of the feeding cylinder 1. A support frame 4 is fixedly installed at the bottom of the feeding cylinder 1 for support. A PLC control box 18 is fixedly installed on one side of the support frame 4, and a PLC controller is installed inside the PLC control box 18. A screw rod 7 is rotatably connected inside the feeding cylinder 1.

[0031] A drive assembly is provided at one end of the feeding cylinder 1 near the inlet to drive the screw rod 7 to rotate and achieve material flow. Specifically, the drive assembly includes a motor reducer 5, which is fixedly installed at one end of the feeding cylinder 1. One end of the screw rod 7 passes through the feeding cylinder 1 and is fixedly connected to the output shaft of the motor reducer 5. A first motor 6 is fixedly installed on one side of the motor reducer 5, and the output end of the first motor 6 is fixedly connected to the input shaft of the motor reducer 5. The first motor 6 is electrically connected to a PLC controller, which controls the start and stop of the first motor 6. When the first motor 6 is working, its output end drives the input shaft of the motor reducer 5 to rotate, which in turn drives the screw rod 7 to rotate inside the feeding cylinder 1 through the output shaft of the motor reducer 5. During the rotation, the screw rod 7 conveys the material in the feeding hopper 2 towards the outlet of the feeding cylinder 1.

[0032] A weighing assembly is installed at one end of the feeding cylinder 1 near the discharge port to weigh the material being conveyed out of the feeding cylinder 1. Specifically, the weighing assembly includes two L-shaped fixing frames 11, which are symmetrically fixed on the outer wall of the feeding cylinder 1 and located on both sides of the discharge port. Support blocks are fixed on the sides of the two L-shaped fixing frames 11 that are close to each other. Weighing sensors 13, electrically connected to the PLC controller, are fixed on each of the two support blocks. A common weighing hopper 12 is installed on each of the two weighing sensors 13, and the weighing hopper 12 is located directly below the discharge cylinder 3. When the material falls from the discharge cylinder 3 into the weighing hopper 12, the weighing hopper 12 exerts pressure on the two weighing sensors 13. The two weighing sensors 13 feed back the weighing data to the PLC controller. Once the required measurement is reached, the PLC controller controls the first motor to stop working, thereby stopping the conveying of electrolytic silver powder.

[0033] An antistatic assembly is installed on the feeding cylinder 3 to remove static electricity from the material being conveyed out of the feeding cylinder 1. Specifically, the antistatic assembly includes a fixing plate 8 with a circular hole of the same diameter as the feeding cylinder 3. The feeding cylinder 3 is inserted into the circular hole and fixedly connected to the fixing plate 8. A connecting plate 10 is fixedly connected to one side of the fixing plate 8, and multiple antistatic rods 9 are evenly spaced on the connecting plate 10. One end of each antistatic rod 9 is inserted into one side of the fixing plate 8 and extends to the other side. When the material falls from the feeding cylinder 3, the electrostatic field generated by the multiple antistatic rods 9 removes static electricity from the material, thereby preventing the material from carrying static electricity and causing adverse effects on subsequent processes.

[0034] This application can be used in the field of electrolytic silver powder conveying technology, or in other fields applicable to this application.

[0035] Example 2: Reference Figure 1-4An improvement based on Embodiment 1: A conveyor for conveying electrolytic silver powder, applied in the field of electrolytic silver powder conveying technology, wherein a baffle 17 for sealing is provided at the top opening of the weighing hopper 12, and a through hole is provided on the baffle 17, the bottom of the discharge cylinder 3 passes through the through hole and extends into the interior of the weighing hopper 12, and a discharge cylinder 14 is provided at the bottom of the weighing hopper 12, and the discharge cylinder 14 is connected to the interior of the weighing hopper 12. Inside the discharge cylinder 14, a flap 15 is rotatably connected via a shaft, and the diameter of the flap 15 is the same as the inner diameter of the discharge cylinder 14. A second motor 16 is fixedly mounted on the outer wall of the discharge cylinder 14 via a connecting block, and the output end of the second motor 16 is fixedly connected to the shaft.

[0036] When the material in the weighing hopper 12 reaches the preset weight, it needs to be discharged. At this time, the PLC controller controls the second motor 16 to start. The output end of the second motor 16 drives the shaft to rotate, which in turn drives the flap 15 to rotate inside the discharge cylinder 14, causing the flap 15 to open the discharge port of the discharge cylinder 14, and the material is discharged from the discharge cylinder 14. After the material is discharged, the second motor 16 starts working again, driving the flap 15 to close the discharge port of the discharge cylinder 14.
