Description

Technical Field

[0001] The utility model belongs to the technical field of salt spray testing machines, and more specifically, particularly relates to a salt spray testing machine. Background Art

[0002] The scientific name of the salt spray test machine is "salt spray test chamber". It uses salt spray corrosion to detect the reliability of the sample under test. Salt spray refers to the dispersion system composed of tiny salt droplets in the atmosphere. It is one of the three-proof series of artificial environments. Many companies need to simulate the destructiveness of the ocean climate to the products, so salt spray test chambers come into being. Salt spray test chambers are divided into neutral salt spray and acidic salt spray. The difference lies in the different standards and test methods they meet, also known as "NSS" and "CASS" tests.

[0003] The existing publication number CN219455878U discloses a salt spray tester. Although the concentration of the solution is adjusted by adding dilute hydrochloric acid or sodium hydroxide solution into the modulation tank through the solenoid valve arranged at the bottom of the solution tank and the addition of distilled water is controlled by the solenoid valve of the distilled water tank to adjust the pH value of the solution before atomization, the effect of the automation of the salt spray tester is greatly improved.

[0004] Based on the above, the inventors have discovered the following problems: However, after conducting the neutral salt spray or acidic salt spray test, the salt spray inside the test chamber is not completely removed, and one type of salt spray still adheres to the inside of the test chamber. When the detection component is subsequently replaced with another type of salt spray, the residual salt spray from the previous type will have a certain impact on the detection structure.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a salt spray test machine is provided to achieve a more practical purpose. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a salt spray test machine to solve the problem that after the current experiment, the internal salt spray is not removed cleanly, which affects the test results of the test pieces in another subsequent salt spray test.

[0007] The utility model provides a salt spray test machine, which is achieved by the following specific technical means:

[0008] A salt spray test machine comprises a test box, wherein first box covers are hingedly connected to both sides of the top of the test box, a salt spray box is fixedly passed through the outer wall of one side of the test box, a second box cover is hingedly connected to the top of the salt spray box, a salt spray pot is placed inside the salt spray box, an electric control valve is fixed on the top of the salt spray pot, an atomizing nozzle is fixed on the top of the electric control valve, a support box is passed through and fixed on the other side of the test box, an air baffle and a drying cotton plate are detachably installed on one side of the support box, a support rod is fixed to the middle of the inner wall of the support box, a first servo motor is fixed to the middle of the support rod, and a ventilation fan blade is fixed to the power output end of the first servo motor.

[0009] Furthermore, a first slide groove and a second slide groove are formed through the top of one side of the support box, the air baffle plate is slidably connected to the first slide groove, and the drying cotton plate is slidably connected to the second slide groove.

[0010] Furthermore, two salt spray tanks are provided, and the two salt spray tanks are respectively filled with neutral salt spray and acidic salt spray.

[0011] Furthermore, a support plate is fixed below the middle of the inner wall of the salt spray box, grooves are penetrated on both sides of the middle of the bottom of the support plate, limiting rings are fixed on the tops of the two grooves, and the two salt spray tanks are respectively located inside the two limiting rings.

[0012] Furthermore, a second servo motor is fixed through one side of the outer wall of the salt spray chamber, a rotating shaft is fixed to the power output end of the second servo motor, and transmission blocks are fixed on both sides of the middle of the rotating shaft.

[0013] Furthermore, the middle parts of the two rotating shafts are respectively arranged in a one-to-one correspondence with the middle parts of the two grooves, and the transmission block is arranged in an eccentric shape.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, the fan blades are driven to rotate by the first servo motor, so that the air flow inside the test box can be fully mixed inside, and the salt mist is fully in contact with the object to be tested. When a different salt mist needs to be replaced, the air baffle is first removed and the first box cover is opened, and the drying cotton board is inserted into the second slide slot, and the first servo motor is started to rotate in the opposite direction, and the gas inside the test box is blown to the drying cotton board, and the salt mist is absorbed by the drying cotton board, so as to quickly remove another salt mist remaining inside the test box, improve the accuracy of the test result, and make the internal salt mist disperse more thoroughly during the test.

[0016] 2. In the utility model, by starting the second servo motor to rotate, the rotating shaft is driven to rotate, and then the two transmission blocks are driven to rotate. The transmission block is eccentrically arranged. When the transmission block rotates with the rotating shaft, the horizontal height of the top will change, and the salt spray tank is always in contact with the top of the transmission block due to the influence of gravity, so that the salt spray tank is shaken up and down to shake the neutral salt mist and acidic salt mist inside evenly, so as to achieve the effect that the neutral salt mist and the acidic salt mist can maintain uniform density before spraying.

[0027] Among them, a first slide groove 61 and a second slide groove 71 are opened through the top of one side of the support box 5, the air baffle plate 6 is slidably connected to the first slide groove 61, and the drying cotton board 7 is slidably connected to the second slide groove 71. The first slide groove 61 and the second slide groove 71 are set so that the air baffle plate 6 and the drying cotton board 7 can be quickly disassembled and installed on the top of the support box 5. When it is necessary to remove the salt mist remaining in the test box 1, the fan blades are driven to rotate clockwise by starting the first servo motor 9 to blow the gas inside the test box 1 toward the drying cotton board 7, and the salt mist is absorbed by the drying cotton board 7. Before starting the first servo motor 9, it is necessary to remove the air baffle plate 6 and open the first box cover 2 at the same time, so that external airflow enters and the airflow can mix with the drying cotton board 7 to accelerate the discharge of internal salt mist. When conducting the test, the first servo motor 9 can be started to drive the fan blades 10 to rotate counterclockwise, so that the airflow inside the test box 1 can be fully mixed inside, so that the salt mist is in full contact with the object to be tested.

[0028] Among them, two salt spray tanks 14 are provided, and the two salt spray tanks 14 are filled with neutral salt spray and acidic salt spray respectively. By arranging an electric control valve 15 on the top of the salt spray tank 14, the two salt spray tanks 14 can be controlled to spray salt spray separately, and the neutral salt spray and acidic salt spray in the salt spray tank 14 are sprayed separately into the test box 1 through the atomizing nozzle 16.
