The intersection of the circumferential surface of the tank body and the inclined surface is in the corrosion of the liquid for a long time, which is easy to cause leakage. At this time, the leaked liquid will flow into the liquid storage rack, and the liquid will first accumulate on the top of the pressing plate. When it accumulates to a certain weight, it will drive the pressing plate to move downward.

The cross block moves up and down to stir the liquid at the bottom of the tank to the top to prevent sedimentation; Step 3: The rotation of gear 2 drives the nozzle to rotate and spray, which is conducive to cleaning the dead corners of the inner wall of the tank. When the tank is corroded by the test liquid and leaks, the liquid will flow into the liquid storage rack. When it accumulates to a certain weight, the pressure plate moves downward to release the L-shaped block and fully display the warning sign to remind the operator.

[0015] The present invention provides a device and method for pre-dispensing a forming foil test liquid, which has the following beneficial effects: (1) The invention detects the rotation speed of the stirring blade through a rotation speed detection device, and the viscosity of the liquid can be detected by the change in the rotation speed of the stirring blade. Through the setting of the pre-configured detection device, the sliding rod is driven to move by a rotating motor in conjunction with a rotating shaft, a No. 1 belt, a rotating rod, a connecting button and a circular groove block. Because the sliding rod is slidably installed on the inner wall of the fixed rod, the circular groove block can only move back and forth left and right, that is, the sliding rod moves back and forth left and right. The movement of the sliding rod drives the movement of the trigger block, which cooperates with the trigger block, a No. 1 spring, a docking groove and a docking groove so that the liquid inside the storage tank will flow out and be transported to the tank body through a pipeline. Controlling the flow of multiple liquids helps to reduce the waste of raw materials. Through precise metering, it can ensure that each raw material is fully utilized and reduce the loss caused by excessive or uneven mixing.

[0016] (2) The invention, through the setting of the stirring device, drives the stirring blade to rotate by rotating the rotating rod, and the rotation of the stirring blade will mix the liquid in the tank body. The rotation of the rotating rod cooperates with the receiving rod, the round rod and the scraper 1 to scrape off the liquid remaining on the inner wall of the tank body. In the process of multi-batch production, timely scraping off the residual liquid on the inner wall of the tank body can prevent cross contamination between different batches of products and ensure product quality. The rotation of the scraper 1 drives the arc blade to rotate, and the arc blade can help reduce the vortex and dead zone generated by the liquid during the stirring process, which can improve the stirring efficiency and ensure a more uniform mixture. The rotation of the receiving rod also drives the rotation of the scraper 2, and the scraper 2 will clean the inclined surface of the inner wall of the tank body. The receiving rod cooperates with the connecting rod and the spiral groove to make the cross block move back and forth up and down. The reciprocating movement of the cross block will drive the liquid deposited on the bottom of the inner wall of the tank body to mix upward, which helps to break the density difference and temperature gradient in the liquid, thereby promoting the mixing of substances inside the liquid and improving the stirring efficiency.

[0017] (3) In the present invention, by setting up a stirring device, the rotating rod also drives the gear to rotate while rotating. The test liquid of the chemical foil is corrosive to a certain extent. The intersection of the circumferential surface and the inclined surface of the tank body is exposed to the corrosion of the liquid for a long time, which can easily cause leakage. At this time, the leaked liquid will flow into the liquid storage rack. The liquid will first accumulate on the top of the pressure plate. When it accumulates to a certain weight, it will drive the pressure plate to move downward, and the movement of the pressure plate will drive the cylinder to move.

[0018] (4) The invention, through the setting of the warning device, rotates the nozzle by rotating gear one in coordination with gear two and the fixed button. The rotation of the nozzle can make the cleaning water flow spray in a more complex trajectory and a larger coverage area, so that the residual substances inside the tank can be more effectively cleaned, including corners and gaps that are difficult to reach directly. The cylinder moves in coordination with the T-shaped block, L-shaped block and short rod to make the plug block disengage from the hollow button. At this time, the L-shaped block will lose support and rotate. The rotation of the L-shaped block drives the warning sign to move. By fully displaying the warning sign, the attention of the staff can be quickly attracted, so that they can find the leakage in time and take measures quickly. When the warning sign is not in use, the L-shaped block is reset and the plug block, hollow button, L-shaped block and No. 3 spring are used to fix the L-shaped block, which helps to save space.

The reciprocating movement of the cross block 26 drives the liquid deposited on the bottom of the inner wall of the tank body 2 to mix upward, which helps to break the density difference and temperature gradient in the liquid, thereby promoting the mixing of substances inside the liquid and improving the stirring efficiency. The rotating rod 13 rotates while the gear 28 rotates. The test liquid of the chemical foil has a certain degree of corrosiveness. The intersection of the circumferential surface and the inclined surface of the tank body 2 is in the corrosion of the liquid for a long time, which is easy to cause leakage. At this time, the leaked liquid will flow into the liquid storage rack 29. The liquid will first accumulate on the top of the pressing plate 210. When it accumulates to a certain weight, it will drive the pressing plate 210 to move downward. The movement of the pressing plate 210 drives the cylinder 211 to move. The rotation of gear 1 28 drives gear 2 30 to rotate, the rotation of gear 2 30 drives the fixed button 31 to rotate, the rotation of fixed button 31 drives the nozzle 32 to rotate, the rotation of nozzle 32 can make the cleaning water flow spray with a more complex trajectory and a larger coverage area, so that the residual substances inside the tank body 2 can be more effectively cleaned, including corners and gaps that are difficult to reach directly, and the movement of cylinder 211 contacts the inclined surface of T-shaped block 36 so that T-shaped block 36 moves outward, and the movement of T-shaped block 36 contacts L-shaped block 37 so that L-shaped block 37 slides along short rod 35, and the movement of L-shaped block 37 also drives the insertion block 38 to move. When the insertion block 38 is separated from the hollow button 3 3, the L-shaped block 37 will lose its support and rotate. The rotation of the L-shaped block 37 drives the warning sign 39 to move. By fully displaying the warning sign 39, the attention of the staff can be quickly attracted, so that they can discover the leakage in time and take measures quickly. When the warning sign 39 is not in use, the L-shaped block 37 can be reset. At this time, the inclined surface of the plug block 38 will contact the outer wall of the hollow button 33, so that the plug block 38 moves toward the inner wall of the L-shaped block 37 and compresses the No. 3 spring. When the plug block 38 and the inner wall of the hollow button 33 are at the same level, the No. 3 spring is released and drives the plug block 38 to be inserted into the inner wall of the hollow button 33. At this time, the L-shaped block 37 is fixed, which helps to save space.
