Description

Technical Field

[0001] This utility model belongs to the field of coating performance testing technology, specifically relating to an auxiliary instrument for testing the non-stick drying time of coatings. Background Technology

[0002] Road marking paint is a type of paint applied to roads to mark road lines. Road markings are an important part of traffic facilities; clear and complete road markings provide drivers and pedestrians with good conditioned reflexes, effectively reducing accidents and improving traffic efficiency.

[0003] Road marking paint should generally meet several performance requirements, including clear marking effect, strong adhesion, good durability, short drying time, and anti-skid properties. The drying performance of these aspects needs to be tested and measured using non-stick tires.

[0004] The existing non-stick coating tester requires a timer to be used for testing. Since the non-stick equipment weighs 15.8 kg, it is required to roll once every 30 seconds for each test. The entire test is conducted manually by personnel, which is physically demanding and also affects the testing efficiency to some extent. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an auxiliary instrument for testing the drying time of non-stick coatings. This instrument aims to solve the problem that existing non-stick coating testing instruments require the use of a timer for testing. Since the non-stick equipment weighs 15.8 kg, each test requires rolling once every 30 seconds, and the entire process involves manual swinging, which is physically demanding and also affects the testing efficiency.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an auxiliary instrument for testing the drying time of non-stick coatings, including a placement frame. A dustproof protection mechanism is installed on the top of the placement frame, and a sample plate is placed at the bottom of the placement frame. A timing test mechanism is jointly installed inside and at the front end of the placement frame. The timing test mechanism includes a test component, which is installed inside the placement frame. The test component includes a lead screw sleeve, a guide sleeve, and a drive motor. A mounting frame is fixed inside the lead screw sleeve and the guide sleeve. A foam anti-slip pad is provided in the middle of the mounting frame, and a non-stick coating tester is placed between the two foam anti-slip pads. A timing drive component is installed at the front end of the placement frame.

[0009] Furthermore, the test assembly includes a mounting frame, which is disposed on both sides inside the placement frame. A transmission screw is installed in the middle of one of the mounting frames, and a drive motor is installed at one end of the transmission screw. A screw sleeve is screwed around one side of the transmission screw. A guide rod is fixed inside the other mounting frame, and a guide sleeve is movable around one side of the guide rod.

[0010] Furthermore, the guide rod and the guide sleeve are connected by a movable guide, and the guide rod and the transmission screw are horizontally aligned.

[0011] Furthermore, the dimensions of the handles at both ends of the non-stick tire tester are matched with the dimensions of the corresponding foam anti-slip inner pad in the middle.

[0012] Furthermore, the timing drive component includes a first connecting line, one end of which is connected to a drive motor, and the other end of which is connected to a controller. A second connecting line is connected to one side of the controller, and a timer is connected to the end of the second connecting line.

[0013] Furthermore, the controller is electrically connected to the drive motor and the timer via the first connection line, the second connection line, and the timer, respectively.

[0014] Furthermore, the dustproof protection mechanism includes a hinge, which is installed on the upper side of the placement frame. One side of the hinge is connected to an upper cover, and a rotating frame is provided on the upper side of the upper cover. The rotating frame has rotating sleeves at both ends, and a pressing frame is fixed on one side of the rotating sleeves.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] During testing, the operator can activate the drive motor via the controller to rotate the lead screw. The lead screw sleeve, acting in conjunction with the lead screw, moves the inner support frame and the foam anti-slip pad. Since one end of the non-stick tester is pressed into the center of the foam anti-slip pad, this movement will cause the other end of the non-stick tester, along with another set of support frames, the foam anti-slip pad, and the guide rod and guide sleeve, to undergo lateral displacement. Thus, the non-stick tester can press uniformly onto the sample plate and move, allowing the operator to observe the non-stick test. If paint is stuck to the tire tread, personnel can clean the tire with a cotton cloth moistened with acetone or methyl ethyl ketone. The timer can be used for time recording and timing. After each test component goes through a process, the timer will count for thirty seconds. After thirty seconds, it will send a signal to the controller through the second connection line. The controller will then control the drive motor to perform the drive operation again. This process is repeated until the tire tread of the non-stick test instrument is free of paint. The time that the timer stops at this point is the "non-stick time". This completes the paint non-stick drying time test.

[0018] When not in use, the upper cover of this utility model's daily storage rack can be rotated to cover the area, effectively preventing dust and debris from entering the testing area. This helps to ensure a relatively clean environment during subsequent testing, thereby improving the reliability of the test data. When testing is required, personnel only need to use the hinge to flip the upper cover. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is an auxiliary instrument for testing the drying time of non-stick coatings, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the device includes a placement rack 1, with a dustproof protection mechanism 2 installed on top of the placement rack 1. A sample plate 3 is placed at the bottom of the placement rack 1. A timing test mechanism 4 is installed inside and at the front end of the placement rack 1. The dustproof protection mechanism 2 includes a hinge 21, which is installed on the upper side of the placement rack 1. An upper cover 22 is connected to one side of the hinge 21, and a rotating frame 23 is provided on the upper side of the upper cover 22. Rotating sleeves 24 are movable at both ends of the rotating frame 23, and a pressing frame 25 is fixed on one side of the rotating sleeves 24. When the placement rack 1 is not in use, the personnel can rotate the upper cover 22 to cover it, which can effectively prevent dust, debris, etc. from entering the test area, so as to help the area achieve a relatively clean environment during subsequent tests, thereby improving the reliability of test data. When testing is required, the personnel only need to use the hinge 21 to flip the upper cover 22.

[0027] The timing test mechanism 4 includes a test component 41, which is installed inside the placement frame 1. The test component 41 includes a mounting frame 411, which is located on both sides of the placement frame 1. A transmission screw 412 is mounted in the middle of one mounting frame 411, and a drive motor 413 is mounted at one end of the transmission screw 412. A screw sleeve 414 is screwed onto one side of the transmission screw 412. A guide rod 415 is fixed inside the other mounting frame 411, and a guide sleeve 416 is movably mounted on one side of the guide rod 415. The guide rod 415 and the guide sleeve 416 are connected by a movable guide connection. The guide rod 415 and the transmission screw 412 are horizontally aligned. A mounting frame 42 is fixedly provided on the inner side of the lead screw sleeve 414 and guide sleeve 416. A foam anti-slip pad 43 is provided in the middle of the mounting frame 42, and a non-stick tester 44 is placed between the two foam anti-slip pads 43. The size of the handles at both ends of the non-stick tester 44 matches the opening size of the corresponding foam anti-slip pad 43. A timing drive assembly 45 is installed at the front end of the placement frame 1. The timing drive assembly 45 includes a first connecting line 451, one end of which is connected to the drive motor 413, and the other end of which is connected to a controller 452. A second connecting line 453 is connected to one side of the controller 452, and a timer is connected to the end of the second connecting line 453. 454. The controller 452 forms an electrical connection with the first connecting line 451, the second connecting line 453, the drive motor 413, and the timer 454. During testing, the operator can start the drive motor 413 through the controller 452 to rotate the lead screw 412. At this time, the lead screw sleeve 414, which interacts with the lead screw, can move the mounting frame 42 and the foam anti-slip pad 43 on its inner side. Since one end of the non-stick tester 44 is pressed into the middle of the foam anti-slip pad 43, this movement will cause the other end of the non-stick tester 44 and another set of mounting frames 42 and foam anti-slip pads 43 to move laterally in coordination with the guide rod 415 and the guide sleeve 416. Thus, the non-stick tester 44... The test instrument 44 can be pressed and moved at a uniform speed on the sample plate 3. Personnel can observe whether there is paint sticking to the tire tread. If so, personnel can wipe the tire clean with a cotton cloth moistened with acetone or methyl ethyl ketone. The timer 454 can be used for time recording and timing. After each process of the test component 41, the timer 454 will count for thirty seconds. After thirty seconds, it will send a signal to the controller 452 through the second connection line 453. The controller 452 will control the drive motor 413 to perform the drive operation again. This process is repeated until the tire tread of the test instrument 44 is no longer sticking to the paint. The time that the timer 454 stops at this moment is the "non-sticking time". Thus, the non-sticking drying time test of the coating can be completed.

[0028] Working principle: During testing, the operator can start the drive motor 413 via the controller 452 to rotate the lead screw 412. At this time, the lead screw sleeve 414, which interacts with the lead screw, can move the inner support frame 42 and the foam anti-slip pad 43. Since one end of the non-stick tester 44 is pressed into the middle of the foam anti-slip pad 43, this movement will cause the other end of the non-stick tester 44 and another set of support frames 42 and foam anti-slip pads 43 to move laterally in coordination with the guide rod 415 and guide sleeve 416. Thus, the non-stick tester 44 can press on the sample plate 3 at a uniform speed and move. The operator can observe the movement. The tire tack tester 44 checks for paint adhesion on the tire tread. If so, personnel can clean the tire with a cotton cloth moistened with acetone or methyl ethyl ketone. The timer 454 is used for time recording and timing. After each cycle of the test component 41, the timer 454 counts for thirty seconds. Once thirty seconds have elapsed, a signal is sent to the controller 452 via the second connection line 453. The controller 452 then controls the drive motor 413 to perform the drive operation again. This process is repeated until the tire tread of the non-tack tester 44 is no longer sticky with paint. The time that the timer 454 stops at this point is the "non-tack time". Thus, the non-tack drying time test of the paint can be completed.

[0029] All technical features in this embodiment can be freely combined according to actual needs.
