[0002] Real stone paint is a kind of paint widely used in building exterior wall decoration. It is favored for its imitation of natural stone effect. In order to ensure the quality and performance of real stone paint, a series of performance tests are required.

[0003] The testing method is to first cover the real stone paint on the substrate, and then test its various properties such as water resistance, stain resistance, wash resistance and crack resistance in turn. The current testing method has the following problems: different performance tests need to be carried out in different testing instruments, which makes the testing process longer, and the variety of testing instruments also leads to high testing costs. At the same time, due to the large number of test contents and the long test cycle, it is easy to be interfered with by external environmental factors (such as fluctuations in temperature and humidity and changes in light intensity, etc.) during the test process, which causes certain interference to the accuracy of the experimental results.

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the invention can be implemented in many different ways as defined and covered by the claims.

[0028] See Figure 1 A device for detecting the performance of real stone paint includes a box body 1. The box body 1 is a rectangular cavity structure with an upward opening and a lower partition 11 fixedly connected to the middle part. The lower partition 11 divides the interior of the box body 1 into two rectangular cavities symmetrical on the left and right. A temperature sensor and a refrigeration device are provided at the bottom of the left rectangular cavity (the refrigeration device and the temperature sensor are both existing equipment, not shown in the figure). The refrigeration device is used to cool the rectangular cavity, and the temperature sensor is used to detect the temperature in the rectangular cavity. The two cooperate with each other to ensure that the temperature at the bottom of the left rectangular cavity is always below zero and remains stable.

[0029] A support rod 2 is connected to the left and right side walls of the box body 1 and rotates together. The support rod 2 rotates and passes through the lower partition 11. Two clamping mechanisms 3 are symmetrically connected to the support rod 2. The two clamping mechanisms 3 are respectively located in the two rectangular cavities of the box body 1. The two ends of the support rod 2 are connected to a flip mechanism 4. A box cover 5 is hinged on the box body 1 to match it. An upper partition 51 corresponding to the lower partition 11 is fixedly connected inside the box cover 5. The upper partition 51 divides the box cover 5 into two independent spaces corresponding to the rectangular cavity in the box body 1. Temperature sensors (not shown in the figure) are also provided in the two independent spaces. Heating devices (existing equipment, not shown in the figure) are also provided in the two independent spaces. The temperature sensor and the heating device cooperate with each other to ensure that the temperature in the independent space is always above zero and remains stable. Two testing mechanisms 6 are symmetrically connected to the box cover 5. Two flushing mechanisms 7 are also symmetrically connected inside the box cover 5, and the two flushing mechanisms 7 are respectively located on the left and right side walls of the box cover 5.

[0030] During the specific work, the real stone paint is brushed onto the substrate and after it is air-dried, the substrate is evenly cut into several pieces. In the initial state, the box cover 5 is in the open state. According to the test needs, part of the substrate is taken and placed on the clamping mechanism 3 and fixed by the clamping mechanism 3.

[0031] See Figure 2 and Figure 3 The clamping mechanism 3 includes a support plate 31, and the support plate 31 is fixedly connected to the outer wall of the circumference of the support rod 2. The circumferential side of the support plate 31 is fixedly connected to a rubber strip 32. The upper end surface of the support plate 31 is fixedly connected to four mounting seats 33 in a matrix arrangement. The two corresponding mounting seats 33 on the left and right are jointly rotatably connected to a pressure plate 34. The lower end surface of the pressure plate 34 is fixedly connected to a pressure strip 35. The pressure plate 34 and the support plate 31 are jointly connected to a locking assembly 36.

[0032] See Figure 2 and Figure 3 The locking assembly 36 includes a locking rod 361, which is slidably connected to the support plate 31. A pressing piece 362 is fixedly sleeved on the side wall of the locking rod 361 and located above the pressure plate 34. A locking seat 363 corresponding to the locking rod 361 is fixedly connected to the upper end surface of the support plate 31, and the locking seat 363 is connected to the locking rod 361 by a thread.

[0033] When the lock body 361 is unlocked, the locking rod 361 is first unscrewed from the locking seat 363, and then the pressure plate 34 is lifted up, the substrate is placed on the support plate 31, and then the pressure plate 34 is closed. Then the locking rod 361 is screwed down to feed it downward relative to the locking seat 363. When the locking rod 361 is fed downward a certain distance, the pressure piece 362 abuts against the pressure plate 34, and then the substrate is fixed on the support plate 31 through the pressure strip 35, and then the box cover 5 is closed. The box body 1 and the box cover 5 form two closed spaces that do not interfere with each other under the separation of the upper partition 51 and the lower partition 11. At this time, the support rod 2 can be driven to rotate by the turning mechanism 4 to adjust the angle of the support plate 31. When the support plate 31 is in a horizontal state or the tilt angle is small, the support plate 31 together with the rubber strip 32 on its side can divide the rectangular cavity in the box body 1 into two upper and lower spaces again.

[0034] See Figure 1 The flip mechanism 4 includes a drive assembly 41, and the left and right outer walls of the box body 1 are fixedly connected to the drive assembly 41. The drive assembly 41 includes two fixed plates fixedly arranged on the outer wall of the box body 1, and a mounting rod 42 is fixedly installed between the two fixed plates. A rack 43 is connected to the mounting rod 42 for sliding back and forth. A gear 44 is engaged above the rack 43. The gear 44 is fixedly sleeved on the support rod 2. The end of the rack 43 is fixedly connected to an electric slider 45, and the electric slider 45 is slidably connected to the mounting rod 42.

[0035] During operation, the electric slider 45 slides left and right on the mounting rod 42, driving the rack 43 to slide synchronously, thereby driving the gear 44 to rotate. The rotation of the gear 44 drives the support rod 2 to rotate synchronously, thereby adjusting the angle of the support plate 31.

[0036] See Figure 4 The testing mechanism 6 includes a hanging plate 61, which is fixedly connected to the inner wall of the top of the box cover 5. The horizontal section of the hanging plate 61 is connected to the second electric slider 62 for sliding left and right. The lower end of the second electric slider 62 is fixedly connected to a cylindrical tube 63. The cylindrical tube 63 opens downward and is internally connected to a lifting component 64. The lower end of the lifting component 64 is connected to a knocking component 65, and the lower end of the cylindrical tube 63 is connected to a scraping brush component 66.

[0037] During specific work, the content and process of each type of test are as follows: 1. Crack resistance test: take a substrate and fix it on the support plate 31 located on the left side of the lower partition 11, and then close the box cover 5. At this time, the heating device and the refrigeration device are not working, and the box body 1 and the box cover 5 are at room temperature. The real stone paint coating on the surface of the left substrate is continuously knocked by the knocking component 65. After knocking at one point several times, the position of the cylindrical tube 63 is moved by the No. 2 electric slider 62 to adjust the relative position between the knocking component 65 and the substrate, and then adjust the knocking position. After many adjustments and knocking, open the box cover 5 and observe the difference between the morphology of the real stone paint coating at the knocked and un-knocked parts of the substrate surface. If cracks or falls off are generated on the surface of the real stone paint material at the knocked part, it means that there is a problem with the crack resistance of the real stone paint material. Otherwise, it means that the crack resistance of the real stone paint material is qualified.

[0038] 2. Anti-fouling performance test: Take two substrates and fix them on two support plates 31 respectively. Then, various types of pollution sources prepared in advance are applied from left to right on the real stone paint coating on the surface of the two substrates (the types of pollution sources include but are not limited to oil stains, ink and dirt, etc.). A certain distance is reserved between each pollution source and they do not interfere with each other. After the coating is completed, ensure that the pollutants stay on the surface of the real stone paint for a period of time to ensure their full penetration. At this time, the heating device and the refrigeration device are not working, and the box body 1 and the box cover 5 are at room temperature. Then, water flow with different pressures is sprayed on each pollution source through two flushing mechanisms 7 to simulate the process of natural rainfall or artificial flushing with a water pipe. After a period of time, observe the residual situation of pollutants on the surface of the real stone paint coating under water flow of different pressures, and then evaluate the anti-fouling performance and cleaning effect of the real stone paint under the impact of water flow of different intensities.

[0039] After the above test is completed, remove the substrates on the two support plates 31, and re-fix and clamp a new substrate on the support plate 31 located on the right side of the lower partition 11, and apply various types of pollution sources prepared in advance (pollution source types include but are not limited to oil stains, ink and dirt, etc.) on the surface of the real stone paint from front to back. A certain distance is reserved between each pollution source and they do not interfere with each other. After the coating is completed, ensure that the pollutants stay on the surface of the real stone paint for a period of time to ensure their full penetration, and then close the box cover 5 again, spray the detergent on the surface of the substrate through the right flushing mechanism 7, and then drive the lower end of the cylindrical tube 63 to move back and forth through the right No. 2 electric slider 62 to move back and forth, thereby driving the scraping brush assembly 66 on the right to move left and right, and brush the stains on the right side of the real stone paint surface left and right to simulate the process of manual brushing. After a period of time, observe the residual stains on the real stone paint surfaces on both sides. If there are stains remaining on the surface of the real stone paint, it means that the stain resistance of the real stone paint is unqualified.

[0040] 3. Anti-scratch performance test: Take a substrate and fix it on the left support plate 31, cover the box 1, at this time the heating device and the refrigeration device are not working, the box 1 and the box cover 5 are at room temperature, then the left No. 2 electric slider 62 drives the cylindrical tube 63 to move back and forth, thereby driving the left scraping brush assembly 66 to move left and right, and then scraping the left side of the real stone paint surface left and right, recording the time consumed from the start of scraping to the appearance of wear on the real stone paint surface, and then calculating the number of scraping times based on the time consumed by the No. 2 electric slider 62 to feed back and forth once, and then comparing whether it meets the standard of the number of scraping times.

[0041] 4. Freeze-thaw performance test: Take two substrates and fix them on the left and right support plates 31 respectively, cover the box 1, and use the heating device and the refrigeration device in conjunction with the temperature sensor to create high and low temperature environments above and below the left support plate 31 respectively to simulate the high temperature outdoor environment in summer and the low temperature outdoor environment in winter. Then, the rack 43 is driven to move by the No. 1 electric slider 45, and the support rod 2 is driven to rotate through the gear 44, and then the real stone paint is periodically switched between high and low temperature environments. After several repetitions, the surface morphology of the real stone paint on the left is compared with the surface morphology of the real stone paint on the right. If bubbling, falling off or discoloration occurs on the surface of the real stone paint on the left, it means that there is a problem with the freeze-thaw performance. Otherwise, it means that it meets the standards.

[0042] See Figure 5 The lifting assembly 64 includes a sleeve 641, which is fixedly mounted on the outer wall of the cylindrical tube 63. A small motor 642 is fixedly connected to the sleeve 641. The drive shaft of the small motor 642 passes through the sleeve 641 and the cylindrical tube 63 and is connected to the lifting module 643.

[0043] See Figure 5 The lifting module 643 includes a rotating wheel 6431, which is located inside the cylindrical tube 63 and is fixedly connected to the driving shaft of the small motor 642. The rotating wheel 6431 is connected to a hinged plate 6432 when it rotates away from the end face of the small motor 642, and the lower end of the hinged plate 6432 is connected to the knocking assembly 65.

[0044] See Figure 4 and Figure 5The knocking assembly 65 includes two annular partitions 651 fixedly connected to the cylindrical tube 63 in the upper and lower parts, and a knocking hammer 652 is slidably connected in the two annular partitions 651. The knocking hammer 652 is a cylindrical cavity structure. The upper end of the knocking hammer 652 is slidably connected to a connecting rod 653. The upper end of the connecting rod 653 is rotatably connected to the hinged plate 6432. The lower end of the connecting rod 653 is fixedly connected to the No. 1 magnetic plate 654. The inner wall of the knocking hammer 652 is fixedly connected to the No. 2 magnetic plate 655. The No. 1 magnetic plate 654 and the No. 2 magnetic plate 655 attract each other under the action of magnetic force. The outer wall of the knocking hammer 652 is fixedly sleeved with a circular ring 656, and the circular ring 656 is connected to the upper annular partition 651 through a force storage spring 657.

[0045] During operation, the small motor 642 rotates to drive the rotating wheel 6431 to rotate, and then drives the connecting rod 653 to move up and down periodically through the hinge plate 6432. In the initial stage of the upward movement of the connecting rod 653, the magnetic force between the first magnetic plate 654 and the second magnetic plate 655 is greater than the elastic force of the storage spring 657, so that the hammer 652 and the ring 656 can be driven to move upward synchronously through the first magnetic plate 654 and the second magnetic plate 655. In this process, the storage spring 657 is compressed, and the hammer 652 rises to a certain height. Later, as the force storage spring 657 continues to be compressed, its elastic force is greater than the magnetic force between the No. 1 magnetic plate 654 and the No. 2 magnetic plate 655, causing the No. 1 magnetic plate 654 and the No. 2 magnetic plate 655 to separate, and the knocking hammer 652 knocks downward on the real stone paint under the action of the force storage spring 657. Then, when the connecting rod 653 drops, the No. 1 magnetic plate 654 also drops synchronously and fits with the No. 2 magnetic plate 655 again. This process is repeated, which can realize the reciprocating knocking of the real stone paint on the surface of the substrate, and then the above-mentioned anti-cracking performance test can be completed.

[0046] See Figure 4 and Figure 5 The scraper assembly 66 includes a connecting seat 661, which is slidably mounted on the lower end of the cylindrical tube 63. The side walls of the connecting seat 661, the cylindrical tube 63 and the knocking hammer 652 are all provided with slots, and a plug-in plate 662 is slidably inserted into the corresponding slot. The lower end of the connecting seat 661 of the scraper assembly 66 on the left side of the upper partition 51 is evenly fixedly connected with a plurality of scraper strips 663 along the circumferential direction, and the lower end of the connecting seat 661 in the scraper assembly 66 on the right side of the upper partition 51 is symmetrically fixedly connected with two mounting plates 664 front and back, and a plurality of rubber brushes 665 are evenly fixedly connected to the front and back of the lower end face of the mounting plate 664.

[0047] During specific work, when conducting the crack resistance test, the insert plate 662 is removed from the slot, and the connecting seat 661 is removed from the cylindrical tube 63, so that the knocking hammer 652 can move up and down normally in the cylindrical tube 63 and knock the real stone paint on the surface of the substrate. When conducting the stain resistance test and the scratch resistance test, the connecting seat 661 is re-installed on the bottom end of the cylindrical tube 63, and the insert plate 662 is re-inserted into the slot. At this time, the knocking hammer 652 is confined in the cylindrical tube 63, and its lowermost end is higher than the rubber brush 665 and the scraper 663. Therefore, when the No. 2 electric slider 62 drives the cylindrical tube 63 to move left and right, the scraper 663 and the rubber brush 665 can both abut against the surface of the real stone paint when moving, and the stain resistance test and the scratch resistance test can be carried out normally.

[0048] See Figure 4 The flushing mechanism 7 includes an outer tube 71. The upper partition 51 and the side wall of the box cover 5 are fixedly connected with the outer tube 71 extending in the left and right directions. The end of the outer tube 71 close to the upper partition 51 is fixedly sleeved with a tube seat 72 for sealing. The tube seat 72 is fixedly connected to the upper partition 51. The end of the outer tube 71 close to the tube seat 72 is fixedly connected to the water inlet pipe 73. The water inlet pipe 73 passes through the top of the box cover 5 and is connected to the external water pipe. The outer tube 71 is connected to an adjusting component 74.

[0049] See Figure 4 and Figure 6 The adjusting assembly 74 includes an inner tube 741, which is slidably connected to the outer tube 71. The end of the inner tube 741 away from the tube seat 72 is located outside the box cover 5 and two limit blocks 742 are symmetrically fixedly connected to its outer wall. The inner tube 741 and the limit blocks 742 are slidably connected to the limit seat 743. The limit seat 743 is fixedly connected to the box cover 5. The left end of the limit seat 743 is connected to the transformer module 744.

[0050] See Figure 1 、 Figure 5 、 Figure 6 and Figure 7 The transformer module 744 includes a cylindrical plug 7441, which is rotatably connected to the end of the inner tube 741 away from the tube seat 72. The end of the cylindrical plug 7441 away from the limit seat 743 is fixedly connected to a threaded rod 7442. The end face of the limit seat 743 away from the tube seat 72 is fixedly connected to a threaded seat 7443 with a cavity inside. The threaded rod 7442 passes through the threaded seat 7443 on the left and right and is connected to the threaded seat 7443 by a thread. The side walls of the outer tube 71 and the inner tube 741 are evenly provided with corresponding water outlet grooves 7444 on the left and right. A water drain groove is provided on the front side wall of the box body 1 and is located above the support rod 2. When conducting the anti-fouling performance test, the flushed water flow is retained through the water drain groove. When conducting other performance tests, the water drain grooves are in a blocked state.

[0051] During specific work, when conducting the stain resistance performance test, clean water is continuously introduced into the left water inlet pipe 73 through the external water pipe. The clean water enters the outer pipe 71 from the water inlet pipe 73, and then enters the inner pipe 741 from the outer pipe 71. Finally, it is sprayed out from the water outlet trough 7444 and flushed on the real stone paint, thereby ensuring the normal progress of the stain resistance performance test.

[0052] When it is necessary to adjust the water pressure of the sprayed clean water, the threaded rod 7442 is manually rotated to make the threaded rod 7442 feed toward the position of the inner tube 741 relative to the threaded seat 7443, so that the cylindrical plug 7441 is also fed toward the position of the inner tube 741, driving the inner tube 741 to feed toward the direction of the tube seat 72 relative to the outer tube 71. During this process, the water outlet groove 7444 on the inner tube 741 and the corresponding water outlet groove 7444 on the outer tube 71 are also offset. Since the water inlet amount in the water inlet pipe 73 remains unchanged, the connecting area between the inner tube 741 and the water outlet groove 7444 on the outer tube 71 is reduced when the two are offset, and the sprayed water pressure will increase compared with before, and the water pressure can be adjusted to meet the requirements of the above-mentioned anti-fouling performance test.
