Description

Technical Field

[0001] This application relates to the field of salt spray testing technology, and more particularly to a salt spray testing device for testing industrial coating resins. Background Technology

[0002] Salt spray testing is an accelerated testing method that assesses the corrosion resistance of materials, coatings, or products by artificially simulating marine or industrial salt spray corrosion environments. Its core principle is to use atomized sodium chloride solution to form salt spray, which is continuously or periodically sprayed onto samples within a sealed test chamber. By observing the degree of corrosion (such as blistering, peeling, rusting, etc.) of the samples over a specific time period, its corrosion resistance is quantified.

[0003] In the processing and production of industrial coating resins, the resin needs to be applied to the surface of a coating test panel, and then the coating test panel is placed inside a salt spray testing device to conduct a salt spray test, thereby determining the corrosion resistance of the resin coating and providing data support for product quality control.

[0004] Chinese patent application CN219065228U discloses a rust prevention testing tool, which is essentially a salt spray testing device. It includes a housing, inside which is a workbench for placing a coating test plate and a spray assembly for spraying salt spray onto the coating test plate. The workbench is equipped with a positioning assembly, which includes two support plates symmetrically installed on the coating test plate. A limit frame is rotatably installed on the inner side of the support plates. The two ends of the limit frame are symmetrically connected to studs by threads. One end of the stud extending into the limit frame is movably connected to a clamping plate on its periphery, and the other end of the stud is fixed with a rotating handle.

[0005] Based on this, by inserting both ends of the coating test plate into two limiting frames respectively, and rotating the studs to bring the clamping plates closer to the coating test plate, the ends of the coating test plate can be clamped within the limiting frames, thus achieving rapid fixation of the coating test plate. However, this fixing method requires operators to rotate and adjust the studs one by one, making the clamping and positioning of the coating test plate cumbersome and inefficient, and needs improvement. Utility Model Content

[0006] Based on this, this application provides a salt spray testing device for industrial coating resin testing, which can realize rapid positioning of coating test plates and improve the efficiency of material loading operations.

[0007] The salt spray testing device for industrial coating resin testing provided in this application adopts the following technical solution:

[0008] A salt spray testing device for industrial coating resin testing includes a base assembly. The base assembly has a placement mechanism for placing a coating test plate and a spraying mechanism for spraying salt spray onto the coating test plate. The placement mechanism includes two guide columns connected to the base assembly and a placement platform slidably disposed between the two guide columns. The two sides of the placement platform are respectively hinged with swing clamps. A reset member is provided between the swing clamps and the placement platform. The reset member is used to force the swing clamps to be in normal contact with the placement platform.

[0009] The swing clamp is provided with an extension extending to the outside of the placement platform. The base assembly is also provided with an abutment seat for forcing the swing clamp to rotate away from the placement platform. The abutment seat is spaced apart from the spraying mechanism, and the extension is partially opposite to the abutment seat along the movement path of the placement platform.

[0010] By adopting the above technical solution, when the resin coating is applied to the coating test panel and a salt spray test is required, the placement platform can be moved to the position of the abutment seat. At this time, the abutment seat can partially abut against the extension and force the swing clamps to rotate away from the placement platform. Each swing clamp can automatically remain open, so that the operator can smoothly place the coating test panel on the placement platform, improving the efficiency of the loading operation. Then, by moving the placement platform along the guide column and into the inside of the spraying mechanism, the extension disengages from the abutment seat during this process. Under the elastic force of the reset member, the swing clamps can automatically rotate towards the placement platform, thereby firmly clamping the coating test panel, so that the spraying mechanism can spray salt spray onto the surface of the coating test panel and conduct the salt spray test experiment.

[0011] Optionally, the width of the platform is adjustable; the side wall of the base assembly is provided with a transverse sliding groove, and two guide columns are slidably disposed in the transverse sliding groove; the side of the base assembly is provided with a drive mechanism, which is connected to both guide columns at the same time, to force the two guide columns to move closer to each other at the same time.

[0012] By adopting the above technical solution, the two guide columns are forced to move closer or further away simultaneously through the action of the drive mechanism, which can automatically adjust the width of the placement platform to accommodate the positioning and placement of coating test plates of different sizes, thereby improving equipment compatibility.

[0013] Optionally, the drive mechanism includes two lifting seats that are vertically slidably mounted on the side of the base assembly, a screw rod that passes through the two lifting seats, and two connecting seats that are slidably mounted in the transverse slide groove. Two guide columns are fixedly connected to the two connecting seats respectively. Each connecting seat has a connecting rod that is hinged to each of its two opposite sides. The end of each connecting rod that is away from the connecting seat is hinged to the adjacent lifting seat.

[0014] The screw assembly includes two coaxially fixed threaded sections with opposite thread directions, and each threaded section is threadedly connected to the lifting seat; one of the threaded sections is connected to a drive motor for driving the screw assembly to rotate.

[0015] By adopting the above technical solution, the drive motor is controlled to rotate the screw. Since the threads of the two threaded sections are opposite, the screw can force the two lifting seats to move closer to each other or further away from each other. Then, the connecting rod is used to force the two connecting seats to move away from each other or towards each other, so as to adjust the distance between the two guide columns, thereby driving the adjustment of the width of the platform.

[0016] Optionally, the platform includes two base frames, which are slidably fitted onto two guide columns. Each base frame includes a sliding sleeve and two support columns located at both ends of the sliding sleeve. Each support column has a hinge rod hinged to its end away from the sliding sleeve, and the adjacent hinge rods of the two base frames are hinged to each other.

[0017] By adopting the above technical solution, the adjacent support columns of the two basic frames are connected by hinge rods, which can not only adjust the spacing between the two basic frames, but also restrict the rotation of the two basic frames, so that the orientation of the placement platform can be maintained, making it easy for operators to place the coating test plate on the placement platform.

[0018] Optionally, the outer periphery of the two guide posts is provided with an elastic seal, which is fixed to the inner wall of the base assembly and covers the transverse groove.

[0019] By adopting the above technical solution, the elastic seal can always cover the transverse groove, thereby keeping the base assembly in a sealed state during salt spray testing and reducing the possibility of corrosive salt spray leaking into the external environment.

[0020] Optionally, the spraying mechanism includes an annular base fixed to the inside of the base assembly and salt spray nozzles installed on the inner peripheral wall of the annular base. Multiple salt spray nozzles are provided, and all salt spray nozzles are arranged at intervals along the central axis of the annular base. Two guide columns are jointly inserted through the inside of the annular base.

[0021] By adopting the above technical solution, multiple salt spray nozzles evenly arranged on the inner circumferential wall of the annular base can evenly spray salt spray onto various parts of the platform, which helps to maintain the accuracy of the test results.

[0022] Optionally, the base assembly includes a base base and two side plate seats disposed on two opposite sides of the base base, the two side plate seats and the base base enclosing a salt spray chamber; the opposite sides of the two side plate seats are respectively provided with arc-shaped sliding grooves, and two movable doors are slidably installed between the two adjacent arc-shaped sliding grooves, the two movable doors are provided, and the two movable doors together cover the salt spray chamber.

[0023] By adopting the above technical solution and setting up an arc-shaped movable door, the salt spray chamber can be easily opened and closed, improving the operational convenience for operators.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up a stop seat, when the placement platform moves to the position of the stop seat, the extension can automatically abut against the stop seat and rotate the swing clamps away from the placement platform, thereby keeping each swing clamp in an open state so that the operator can smoothly place the coating test plate on the placement platform and improve the efficiency of the loading operation.

[0026] 2. By setting the width of the placement platform to be adjustable, the drive mechanism can be activated to force the two guide columns to move closer or further away simultaneously, thereby automatically adjusting the width of the placement platform to accommodate the positioning and placement of coating test panels of different sizes and improving equipment compatibility.

[0027] 3. By setting an elastic seal, the elastic seal can always block the transverse slide, thereby ensuring that the base assembly is in a sealed state during the salt spray test, reducing the possibility of corrosive salt spray leaking into the external environment. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a salt spray testing device for detecting industrial coating resins.

[0035] Reference Figure 1 A salt spray testing device for industrial coating resin testing includes a base assembly 1; wherein the base assembly 1 includes a base 11 and two side plate seats 12 symmetrically arranged on two opposite sides of the base 11, the two side plate seats 12 and the base 11 together enclose a salt spray chamber 13; the top of each side plate seat 12 is arc-shaped, and each side plate seat 12 has two arc-shaped grooves 14 on the side near the other side plate seat 12, the two arc-shaped grooves 14 being concentrically arranged.

[0036] In this embodiment, the two arc-shaped slides 14 are defined as the first arc-shaped slide and the second arc-shaped slide. The two first arc-shaped slides, located on the two side plate seats 12, jointly slide and install a movable door 15. Similarly, the two second arc-shaped slides, also located on the two side plate seats 12, jointly slide and install another movable door 15. The movable door 15 is an arc-shaped plate made of transparent acrylic material, capable of sliding smoothly within its corresponding arc-shaped slide 14. It should be noted that, under normal conditions, the two movable doors 15 jointly cover the salt spray chamber 13, and there is partial contact between the two movable doors 15, ensuring a tight seal inside the salt spray chamber 13.

[0037] The base assembly 1 has a placement mechanism 3 for placing the coating test plate and a spraying mechanism 2 for spraying salt spray onto the coating test plate. The spraying mechanism 2 includes an annular base 21 and a salt spray nozzle 22. The annular base 21 is fixed to the top surface of the base 11 and is located in the middle of the salt spray chamber 13. The annular base 21 has a liquid channel for solution flow inside, and the base assembly 1 has a liquid injection device (not shown in the figure) on the outside. The liquid injection device is connected to the liquid channel through a pipe and is used to inject a corrosive solution into the liquid channel.

[0038] There are multiple salt spray nozzles 22, each of which is fixed to the inner circumferential wall of the annular base 21, and all salt spray nozzles 22 are equidistantly arranged around the central axis of the annular base 21; each salt spray nozzle 22 is connected to the liquid channel inside the annular base 21, which enables the solution to be atomized to form salt spray and sprayed out to test the corrosion resistance of the coating test plate.

[0039] Reference Figure 2 The placement mechanism 3 includes guide posts 4 and a placement platform 5. Two guide posts 4 are provided, both passing through the inner side of the annular base 21 and slidably connected to the base assembly 1. (See also...) Figure 3 Each side plate seat 12 is provided with a through transverse slide groove 16, which extends horizontally, and two guide posts 4 are slidably installed in the transverse slide groove 16. In addition, a drive mechanism 6 is provided on the side of the side plate seat 12, which is connected to both guide posts 4 at the same time, and can force the two guide posts 4 to move closer or further away at the same time.

[0040] Specific reference Figure 3 The drive mechanism 6 includes a lifting seat 61, a screw rod 62, a connecting seat 63, and a drive motor 64. Two lifting seats 61 are provided, and both are vertically slidably mounted on the side plate seat 12 away from the salt spray chamber 13. The screw rod 62 is rotatably mounted on the side plate seat 12 and includes two coaxially fixed threaded sections 621, which are threadedly connected to the two lifting seats 61 respectively. The drive motor 64 is fixed to the side of the side plate seat 12, and its output end is coaxially connected to the screw rod 62. Therefore, when the drive motor 64 operates, it drives the screw rod 62 to rotate, allowing the two lifting seats 61 to move closer to or further apart.

[0041] Reference Figure 2 , Figure 3 There are two connecting seats 63, which are slidably disposed in the transverse slide groove 16. Two guide posts 4 are respectively inserted through the transverse slide groove 16 and connected to the two connecting seats 63. Each connecting seat 63 has a connecting rod 631 hinged to its upper and lower sides. The end of each connecting rod 631 away from the connecting seat 63 is hinged to the adjacent lifting seat 61. Based on this, when the two lifting seats 61 move closer to each other or further away from each other under the action of the screw 62, the two guide posts 4 can be moved further away from each other or closer to each other accordingly. In addition, the outer periphery of the two guide posts 4 is provided with an elastic seal 41. In this embodiment, the elastic seal 41 is made of elastic material such as silicone or rubber. The elastic seal 41 is fixed to the inner wall of the side plate seat 12 and can normally block the transverse slide groove 16 to ensure the sealing effect inside the salt spray chamber 13.

[0042] Reference Figure 2 The platform 5 includes two base frames 51, which are slidably fitted onto two guide posts 4, and the distance between the two base frames 51 is adjustable. See details... Figure 4 The base frame 51 includes a sliding sleeve 511 and two support columns 512. The sliding sleeve 511 is slidably fitted onto the guide column 4, while the two support columns 512 are integrally formed at both ends of the sliding sleeve 511. Each support column 512 has a hinge rod 52 hinged to its end away from the sliding sleeve 511. Adjacent hinge rods 52 on the two base frames 51 are hinged to each other. Based on this, when the two guide columns 4 move closer to each other or further away from each other, the two hinge rods 52 can rotate and avoid each other, thereby adjusting the distance between the two base frames 51 and thus adjusting the width of the placement platform 5. This is suitable for positioning and placing coating test plates of different sizes, improving equipment compatibility.

[0043] Each base frame 51 has a sliding sleeve 511 hinged with a swing clamp 53. Two sets of swing clamps 53, located on the two base frames 51, are symmetrically arranged on both sides of the placement platform 5. A reset member 54 is provided between the swing clamp 53 and the sliding sleeve 511. In this embodiment, the reset member 54 is a torsion spring. The torsion spring can always generate an elastic force acting on the swing clamp 53, thereby forcing the swing clamp 53 to rotate normally towards the placement platform 5 and finally fit against the placement platform 5. In addition, each swing clamp 53 has an integrally formed extension 531. The extension 531 can extend to the side of the sliding sleeve 511 away from the other sliding sleeve 511, that is, the outer side of the placement platform 5.

[0044] The side plate seat 12 is fixed with an abutment seat 7, which is close to the side guide surface 71 of the annular base 21. The extension 531 is partially opposite to the abutment seat 7 along the moving path of the placement platform 5. When the operator moves the placement platform 5 and moves it closer to the abutment seat 7, the extension 531 can first abut against the guide surface 71 of the abutment seat 7. Under the guidance of the guide surface 71, the swing clamp 53 can gradually rotate away from the placement platform 5, thereby realizing the automatic opening of each swing clamp 53, so that the operator can smoothly place the coating test plate on the placement platform 5 and improve the efficiency of the loading operation.

[0045] Understandably, when the placement platform 5 moves along the guide post 4 and enters the inner side of the annular base 21 for spray testing, the extension 531 disengages from the abutment seat 7, and the swing clamp 53 can automatically rotate towards the placement platform 5 under the elastic force of the reset member 54, thereby firmly clamping the coating test plate so that the spray mechanism 2 can spray salt spray onto the surface of the coating test plate and conduct salt spray test experiments.

[0046] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
