Description

Technical Field

[0001] This utility model relates to the field of insulating coating production technology, specifically a high-precision batching device for insulating coating production. Background Technology

[0002] As is well known, insulating coatings are widely used in electrical equipment, electronic components and other fields in existing industrial production. Their quality and performance are crucial to the safe operation and service life of related equipment. As a key step in the production of insulating coatings, the accuracy of the batching process directly affects the final performance of the coating.

[0003] Traditional insulating coating batching devices mostly employ relatively simple metering methods, such as relying on manual addition of materials based on experience, or using mechanical metering instruments with limited accuracy.

[0004] First, manual batching makes it difficult to guarantee the accuracy of each batch. It is prone to errors due to the subjective factors and fatigue of the operators, resulting in unstable performance of the produced insulating coating and differences between batches. Simple mechanical measuring instruments are limited by their own precision and cannot achieve high-precision measurement of some key components that require precise proportions.

[0005] When the proportions of these key components deviate, the insulation performance, adhesion, corrosion resistance, and other critical properties of the insulating coating will be affected, which in turn will impact the quality and reliability of downstream products. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a high-precision batching device for the production of insulating coatings, which has the following beneficial effects:

[0019] This high-precision batching device for insulating coating production is equipped with an automatic feeding component.

[0030] Please see Figure 1-4 A high-precision batching device for the production of insulating coatings includes a batching tank 1 with a cavity inside. A discharge pipe 2 with a valve is located on the bottom wall of the batching tank 1. A mixing component is located inside the cavity. An inlet is located at one upper end of the cavity, and a funnel 6 is located inside the inlet. An auxiliary component is located at the lower end of the funnel 6. Symmetrical support rods 3 are arranged around the funnel 6. A weighing component is located on the upper side wall of each support rod 3. A storage tank 9 with an inlet is located on the upper side wall of each support rod 3. An automatic feeding component is located on the bottom wall of the storage tank 9. A liquid level sensor is located inside the storage tank 9. The weighing component includes an auxiliary rod 19, a control motor 8, and a weighing tank 7. The auxiliary rod 19 is symmetrically arranged on the inner side wall of the support rods 3. The control motor 8 is located on the outer wall of one of the support rods 3. The auxiliary rod 19 passes through the support rod 3 and is connected to the output end of the control motor 8. The weighing bucket 7 is located between the two auxiliary rods 19. A weighing system is provided on the bottom wall of the weighing bucket 7. The automatic feeding assembly includes a feeding pipe 11, a feeding motor 12, a feeding rod 18, and a sealing plate 17. The feeding pipe 11 passes through the bottom wall of the storage bucket 9. The feeding motor 12 is located on one side of the feeding pipe 11. The feeding rod 18 passes through the feeding pipe 11 and is connected to the output end of the feeding motor 12. The sealing plate 17 is located on the feeding rod 18 and is adapted to the feeding pipe 11. The device has a built-in remote control system for controlling the above-mentioned device. The control system includes a PLC controller and a human-machine interface.

[0031] During use, firstly, all the raw materials required for the production of insulating coatings, such as resin, curing agent, and additives, are poured into the corresponding storage tanks 9. The storage tanks 9 are located on the upper side wall of the support rod 3, and each storage tank 9 has an independent inlet for easy addition of raw materials. A liquid level sensor is installed inside the storage tank 9, which can monitor the liquid level of the raw materials in the tank in real time.

[0032] The operator inputs the required insulating coating formula parameters for this production run onto the human-machine interface (HMI) of the device's built-in remote control system. These parameters include the precise dosage of each raw material. The HMI is connected to a PLC controller, which is the core of the entire device's control system. It receives and processes various signals and issues instructions according to a preset program. Once the parameters are input and confirmed to be correct, the operator starts the batching program on the HMI.

[0033] After receiving the start command, the PLC controller sends a signal to the feeding motor 12 in the automatic feeding assembly at the bottom of each storage bin 9. The feeding motor 12 starts outputting power, driving the feeding rod 18 to rotate. The sealing plate 17 on the feeding rod 18 rotates accordingly. The sealing plate 17 is adapted to the feeding pipe 11. As the sealing plate 17 rotates, the feeding pipe 11 gradually opens, and the raw material in the storage bin 9 begins to flow downward through the feeding pipe 11. The flowing raw material falls into the weighing bin 7 below.

[0034] The weighing system installed on the bottom wall of the weighing drum 7 begins to measure the weight of the raw material falling into it in real time. The weighing system transmits the weight signal to the PLC controller. The PLC controller continuously compares the real-time weight with the preset target weight. When the weight of the raw material approaches the target value, the PLC controller controls the feeding motor 12 to decelerate, causing the sealing plate 17 to rotate slower, thus achieving micro-feeding and accurately controlling the final weight of the raw material. When the appropriate amount is reached, the PLC controller issues a command to reverse the feeding motor 12, causing the sealing plate 17 to rotate in the opposite direction, closing the feeding pipe 11, and stopping the feeding. At this point, the required amount of raw material is accurately stored in the weighing drum 7.

[0035] After weighing is complete, the PLC controller sends a command to the control motor 8 in the weighing assembly, causing the control motor 8 to start and rotate the auxiliary rod 19. Because the weighing bucket 7 is connected between the two auxiliary rods 19, the weighing bucket 7 rotates accordingly. The rotating weighing bucket 7 pours the weighed material into the funnel 6 above.

[0036] Before entering the mixing tank 1, the raw materials poured into the funnel 6 pass through the auxiliary components at the lower end of the funnel 6. These components control the feeding speed of the raw materials and also perform preliminary mixing and stirring, ensuring that the raw materials are homogenized to a certain extent before entering the mixing tank 1. After preliminary treatment, the raw materials enter the mixing tank 1 through the funnel 6. The mixing tank 1 is equipped with mixing components to fully mix and stir the various raw materials in the mixing tank 1, forming an insulating coating that meets the production requirements.

[0037] In practical use, it is necessary to ensure that the materials are fully mixed in the mixing tank 1. To meet the above requirements, in this embodiment, the mixing component includes a rotating motor 4, a rotating rod 13, and rotating blades 14. The rotating motor 4 is located at the center of the upper side wall of the mixing tank 1. The rotating rod 13 passes through the cavity and is connected to the output end of the rotating motor 4. The rotating blades 14 are located around the rotating rod 13.

[0038] When the raw materials enter the mixing tank 1, the PLC controller sends a command to the rotating motor 4, the rotating motor 4 starts, and drives the rotating rod 13 to rotate. The rotating blades 14 around the rotating rod 13 rotate at high speed, so that they are evenly mixed.

[0039] In practical use, it is necessary to accurately control the material's falling speed and stopping timing. To meet these requirements, in this embodiment, the auxiliary component includes a limiting rod 15, a limiting motor 5, and a limiting plate 16. The limiting rod 15 passes through the lower end of the funnel 6, and the limiting motor 5 is located on one side of the lower end of the funnel 6. One end of the limiting rod 15 is connected to the output end of the limiting motor 5. The limiting plate 16 is arranged in a cross shape around the limiting rod 15 and is adapted to the lower end of the funnel 6.

[0040] When the limit motor 5 in the auxiliary component starts, it drives the limit rod 15 to rotate. The limit plates 16 arranged in a cross around the limit rod 15 also rotate. The limit plates 16 are adapted to the lower end of the funnel 6. The feeding speed can be adjusted by adjusting the angle and rotation speed of the limit plates 16.

[0041] In actual use, it is necessary to ensure that the material maintains stable fluidity at the optimal temperature. In order to meet the above requirements, in this embodiment, the inner wall of the mixing tank 1 is provided with a temperature sensor and a heating element. The heating element is an electromagnetic induction heating coil, and the temperature sensor is connected to the control system.

[0042] In practical use, it is necessary to automatically trigger an alarm when the material level in the storage tank 9 falls below a warning value. To meet this requirement, in this embodiment, an indicator light 10 is provided on the side wall of the storage tank 9, and the indicator light 10 is connected to the liquid level sensor signal.

[0043] Throughout the entire batching process, the liquid level sensor inside the storage tank 9 continuously monitors the remaining amount of raw materials in real time. The liquid level sensor transmits the monitored liquid level signal to the PLC controller in real time. The PLC controller compares the received liquid level signal with the preset lower limit value. When the liquid level sensor detects that the amount of raw materials in the storage tank 9 is less than the preset value, the PLC controller issues a command to make the indicator light 10 set on the side wall of the storage tank 9 light up, prompting the operator to replenish the raw materials in time to ensure the smooth progress of subsequent batching work.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
