Technical Field
[0001] This utility model relates to the field of waterproof coating production technology, specifically to a high-precision metering and conveying equipment for waterproof coatings. Background Technology
[0002] Acrylic waterproof coating is a single-component water-emulsion type waterproof coating made by adding other additives to pure acrylic polymer emulsion as the base material. In order to ensure the production quality and waterproof effect of the waterproof coating, it is necessary to accurately control the amount of each additive. Therefore, it is necessary to use a metering device to measure the amount of additives.
[0003] For example, the announcement number CN210464637U is named Waterproof Coating Metering Device. This device includes a storage bin and a fixed frame. The inner walls of the vertical ends on both sides of the base are provided with guide grooves. The bottom of the fixed frame is bolted with a first servo motor. This metering device adopts a cyclic rotary drive mode, which can realize the continuous displacement and feeding effect of the metering cylinder, and can ensure the continuous and accurate automatic feeding and metering effect of the metering cylinder.
[0004] The above-mentioned device has a relatively complicated metering method, and the excess amount measured is not easy to be recycled and processed. Utility Model Content
[0005] The purpose of this invention is to provide a high-precision metering and conveying device for waterproof coatings, so as to solve the problems mentioned in the background art, which are that the metering method is relatively complicated and the excess amount measured is not easy to be recycled and processed.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision metering and conveying device for waterproof coatings, including a mixing tank;
[0007] Also includes:
[0008] A support frame is installed on the upper part of the mixing tank. A locking frame is connected to one end of the support frame. A storage box is movably installed inside the locking frame. A first placement frame is provided on the outer side of the mixing tank. A transition box is installed above the first placement frame. The transition box is connected to the mixing tank through a pipeline and is located below the storage box. A second placement frame is provided on the outer side of the mixing tank and is located below the first placement frame. A temporary storage box is provided at the upper end of the second placement frame and is connected to the transition box through a pipeline. The temporary storage box and the transition box are connected through a first flexible hose.
[0009] Preferably, a water pump is provided at the bottom of one side of the temporary storage box, one end of the water pump is connected to a return pipe, the other end of the return pipe is connected to a second flexible hose, and the other end of the second flexible hose is connected to the storage box.
[0010] Preferably, a first solenoid valve is provided on the outside of the pipeline between the transition tank and the temporary storage tank, a second solenoid valve is provided on the pipeline between the transition tank and the mixing tank, and a third solenoid valve is installed between the storage tank and the first flexible hose.
[0011] Preferably, a push plate is installed inside the transition box, and an electric push rod is provided on the outside of the filter box away from the mixing box, and the electric push rod is connected to the push plate by a connecting rod.
[0012] Preferably, a first pressure sensor is provided on the surface of the first placement rack, and the first pressure sensor is attached to the bottom of the transition box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By setting a transition tank outside the mixing tank, the third solenoid valve is opened, and the raw materials inside the storage tank enter the transition tank through the first hose. The storage tank uses a first pressure sensor to determine the weight of the outflowing raw materials. After reaching a specified value, the third solenoid valve is closed. After the raw materials enter the transition tank, the second pressure sensor weighs the transition tank. After weighing, an electric push rod drives a push plate to move, pushing the raw materials inside the transition tank into the mixing tank. At this time, the second solenoid valve opens and the first solenoid valve closes. If the raw materials inside the transition tank exceed the measured value, the specified raw materials are discharged and the second solenoid valve is closed. Then, the first solenoid valve is opened, allowing the excess raw materials to enter the temporary storage tank for temporary accumulation. When the raw materials in the temporary storage tank reach a certain value, the raw materials are pumped back to the storage tank through the return pipe and the second hose by a water pump. The design of two layers of pressure sensors can effectively improve the measurement accuracy. Together with the solenoid valve, it can effectively control the raw materials of the waterproof coating that are delivered, and recover the excess raw materials and send them back to the storage tank for storage.
