[0038] Film capacitors are composed of a core, a storage shell and other auxiliary materials. After the core is installed in the shell, epoxy resin needs to be injected for packaging to obtain good capacitor insulation, heat dissipation, moisture resistance and other properties. Therefore, the quality of epoxy resin plays a key role. According to the characteristics of epoxy resin, the main agent and hardener must be mixed in a certain proportion and hardened before obtaining excellent hardness and characteristics.

[0039] The existing main agent and hardener are stored in separate containers of equal capacity. Every time the resin needs to be mixed, it needs to be mixed manually. Workers need to pour the main agent and hardener from separate containers and then weigh them, mix the main agent and hardener and then weigh them repeatedly in a weighing device to obtain epoxy resin that meets the proportion. However, this manual mixing of epoxy resin will lead to inaccurate mixing ratios and cause material waste.

[0040] In view of the problems existing in the existing resin mixing process, the present application proposes a resin mixing and proportioning system, wherein a main agent and a hardener are stored in a storage tank, and two storage tanks are provided, one of which stores the main agent and the other stores the hardener. An overflow port is provided on the side wall of the storage tank, and the overflow port can limit the volume of the main agent or the hardener in the storage tank, and the overflow port is connected to a collecting bucket. A discharge port is provided at the bottom of the storage tank, and the discharge port is connected to a mixing barrel through a pipe. The main agent or the hardener stored in the storage tank can be transported to the mixing barrel through the discharge port and the conveying pipe, so that the main agent and the hardener of fixed volume can be mixed in the mixing barrel. The conveying pipe is provided with an electronic control component, and the electronic control component controls the opening and closing of the output pipe to transport the main agent or the hardener to the mixing barrel. The resin mixing and proportioning system can mix the main agent and the hardener of set volume in the mixing barrel to obtain resin with an accurately mixed ratio, and can also reduce the waste of mixed materials.

[0041] Reference Figures 1 to 3As shown, the resin mixing and proportioning system provided by the embodiment of the utility model includes a storage tank 100, a collecting barrel 800, a mixing barrel 300 and an electronic control component. An overflow port 110 is provided on the side wall of the storage tank 100. The overflow port 110 is located on the outer circumferential side wall of the storage tank 100. One end of the overflow port 110 is connected to the storage tank 100, and the other end is connected to the collecting barrel 800. The collecting barrel 800 is used to collect materials overflowing from the storage tank 100. The excess materials collected by the collecting barrel 800 can be poured back into the storage tank 100 for mixing and proportioning again. When the main agent or hardener exceeds the specified capacity in the storage tank 100, the main agent or hardener flows from the overflow port 110 of the storage tank 100 to the collecting barrel 800, and the collecting barrel 800 collects the overflowing main agent or hardener. When the material in the collecting barrel 800 reaches a certain volume, the material in the collecting barrel 800 is added back to the storage tank 100 for mixing. Such an arrangement can reduce the waste of processing materials.

[0042] It should be noted that a discharge port is provided at the bottom of the storage tank 100, and the discharge port is connected to one end of the output pipe 200, and the other end of the output pipe 200 is connected to the mixing barrel 300. The storage tank 100 is also provided with a feed port 120, and the feed port 120 is located at the top of the storage tank 100. The electronic control component is arranged in the output pipe 200, and the electronic control component can control the opening and closing of the material in the output pipe 200, and can also control the circulation speed of the material in the output pipe 200. It is understandable that there are two storage tanks 100, one of which stores the main agent and the other stores the hardener. When resin mixing is required, the electronic control component is controlled so that the main agent and the hardener are transported to the mixing barrel 300 through the discharge port at the bottom of the storage tank 100 and the delivery pipe connected to the discharge port. The main agent and the hardener are completely discharged from the storage tank 100 and fully mixed in the mixing barrel 300 to obtain a resin with an accurate mixing ratio, so that the mixing time of the main agent and the hardener is short, and the production efficiency is accelerated. In other embodiments, the overflow port 110 of the storage tank 100 is provided with an adjustment plate, and the two ends of the adjustment plate are fixed to the side wall of the storage tank 100 by bolts. The side wall of the storage tank 100 is provided with a slot structure, and the adjustment plate is inserted into the slot of the overflow port 110. The adjustment plate can have a variety of specifications. The adjustment plates of various specifications can enable the storage tank 100 to store different capacities of the main agent or hardener to cope with the mixing of different proportions of the main agent and the hardener.

[0043] It should be noted that the overflow port 110 of the storage tank 100 can limit the volume of the material stored in the storage tank 100, so that the amount of material mixed and prepared each time is fixed, and the quantitatively limited main agent and hardener flow to the mixing barrel 300 through the output pipe 200 under the action of the electronic control component. The main agent and the hardener are mixed in the mixing barrel 300, and finally a resin with a precise proportion of the main agent and the hardener is obtained.

[0044] It should be noted that, refer to Figure 1 and Figure 2 As shown, the electronic control component includes a controller 410 and a solenoid valve 420. The controller 410 is electrically connected to the solenoid valve 420. The solenoid valve 420 is arranged at one end of the output pipe 200 away from the storage tank 100. The solenoid valve 420 can control the opening and closing of the output pipe 200. When the material in the storage tank 100 reaches a specified capacity, the controller 410 controls the solenoid valve 420 to open, so that the material in the storage tank 100 is transported to the mixing barrel 300 for mixing.

[0045] It should be noted that the electronic control component also includes a liquid level sensor, which is arranged on the inner wall of the storage tank 100. When the material in the storage tank 100 reaches a specified capacity, the liquid level sensor feeds back a signal to the controller 410. The controller 410 controls the solenoid valve 420 to open, so as to transport the material in the storage tank 100 to the mixing barrel 300 for mixing and proportioning to obtain the resin. The entire mixing process can be carried out automatically without manual participation, thereby reducing production costs.

[0046] It should be noted that, refer to Figure 1 and Figure 2 As shown, a liquid level gauge 430 is provided on the outer wall of the storage tank 100. The liquid level gauge 430 may be a glass tube type liquid level gauge 430. The height and changes of the material in the storage tank 100 can be displayed through the liquid level gauge 430, so that the changes of the material in the storage tank 100 can be known intuitively.

[0047] It should be noted that, refer to Figure 1 and Figure 3 As shown, a workbench 500 is also included. Specifically, the storage tank 100 and the controller 410 are arranged above the workbench 500, the mixing barrel 300 is placed on the workbench 500, and a avoidance hole is opened on the table plate of the workbench 500. The avoidance hole is used to avoid the discharge port of the storage tank 100 being empty. The output pipe 200 is connected to the discharge port through the avoidance hole, and then the main agent and the hardener are transported to the mixing barrel 300 at the bottom of the workbench 500. The bottom of the workbench 500 is also provided with universal wheels. When the resin mixing and proportioning system is to be transported, the worker only needs to push the workbench 500 to transport it as a whole, which is convenient and fast.

[0048] It should be noted that, refer to Figure 1 and Figure 2As shown, a weighing device 600 is also included. The weighing device 600 is arranged at the bottom of the mixing barrel 300, and the weighing device 600 is placed on the frame of the workbench 500. The mixing barrel 300 is placed above the weighing device 600. The weighing device 600 can weigh the mixing barrel 300 and the resin in the mixing barrel 300, and the mixed resin is weighed multiple times to obtain an average weight of the mixed resin. The weight of the mixed resin is compared with the average weight each time. The resin with little difference in weight data is obtained by obtaining an accurately mixed ratio. Such a setting can indirectly measure whether the mixed resin in the mixing barrel 300 reaches an accurate mixing ratio.

[0049] It should be noted that, refer to Figure 2 and Figure 3 As shown, the device further includes a driver 700 and a material barrel. The driver 700 may be a motor, which is installed on the workbench 500. The material barrel stores materials, and the material barrel is connected to the storage tank 100 through a pipeline. The driver 700 drives the materials in the material barrel to the storage tank 100. In other embodiments, the driver 700 may be installed on the outer wall of the storage tank 100, and the driver 700 installed on the outer wall of the storage tank 100 may move with the storage tank 100, so as to facilitate the position change of the storage tank 100.

[0050] It should be noted that the storage tank 100 is made of Teflon material. Since resins have certain corrosiveness, they can react with certain substances, especially under specific environments and conditions. Teflon is a high molecular polymer prepared by polymerization of tetrafluoroethylene as a monomer. This material is resistant to acids and alkalis, and various organic solvents. It is almost insoluble in all solvents and has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance. Using Teflon-made storage tanks 100 to store materials can prevent the storage tanks 100 from being corroded by the main agent or hardener. At the same time, Teflon itself has very excellent performance and can extend the service life of the storage tank 100.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
