Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of brushing, specifically relates to a detachable brushing device for controlling sample film coating thickness. BACKGROUND

[0002] At present, in many building material detection related standards, the substrate surface film coating thickness is fixed in detail, aiming to evaluate the physical and mechanical properties of the coating film by preparing samples. The substrate surface film coating thickness has a significant impact on the setting time of the material and its physicochemical properties.

[0003] For example, when the substrate surface film coating is thin, the sample cannot withstand the impact of high-strength water pressure, and the sample has poor impermeability. When the substrate surface film coating is thick, it will have the following effects on the sample: first, the film setting time is prolonged, which affects the test efficiency; second, for the film with high viscosity, it is easy to wrap more bubbles during stirring and coating, and the thick film is not conducive to the discharge of bubbles, resulting in regional protection defects of the film; finally, when the substrate surface is coated too thick, it will hinder the discharge of water vapor inside the substrate, and the accumulation of water vapor will reduce the bonding ability of the substrate and the film, and thus weaken the protection ability of the film to the substrate. Therefore, reasonable control of the thickness of the substrate surface film coating is beneficial to fully exert the performance of the film and improve the protection ability of the film to the substrate. For example, the Chinese patent with publication number CN219798938U discloses a waterproof coating sample preparation mold, the technical scheme of which includes a mold table, a bottom plate and a scraper. The bottom of the mold table is fixed with multiple support legs, a sample groove is formed through the mold table, a recovery groove is formed on one side of the sample groove, fixed sliding strips are symmetrically arranged on both sides of the sample groove, a sliding groove is symmetrically formed in one end of the scraper and connected with the fixed sliding strips, connecting plates are symmetrically arranged on both sides of the sample groove, a base is connected to the bottom of the connecting plate, a lifting knob is rotatably arranged on the base, a threaded groove is formed in the center of the lifting knob and extends into the base, a screw rod is connected with the threaded groove, the bottom plate is slidably arranged in the sample groove, a rotating groove is formed in one end of the bottom plate close to the base, and the screw rod is rotatably connected with the rotating groove. The waterproof coating is poured into the mold formed by the bottom plate and the sample groove, and the waterproof coating is scraped flat by the scraper to make the sample thickness uniform, and the sample thickness is adjusted by the lifting knob.

[0004] However, during actual test operation, due to the sample precision, the sample surface may not be flat, which leads to the problem of uneven sample surface film coating thickness based on the same brushing height. At the same time, the existing sample preparation mold can only coat the horizontal upper surface of the sample, and cannot coat the inclined surface (such as a wedge-shaped sample) at the same time. Therefore, when coating such samples, a custom-made mold needs to be replaced, which is very inconvenient to operate. SUMMARY

[0008] According to one specific implementation and preferred aspect of the utility model, the adjusting component comprises an adjusting seat, the brushing component is connected to the adjusting seat and can be adjusted to flip up and down, and the base plate is rotatably connected to the adjusting seat about a horizontal axis. Here, the adjusting is facilitated, and based on the base plate and the brushing component being connected to the same adjusting seat, the stability of the relative position between the base plate and the brushing end is ensured, and the control precision of the coating thickness is improved.

[0009] Preferably, the adjusting component further comprises a horizontal movement module movably connected to the base along the horizontal direction, wherein the adjusting seat is movably connected to the horizontal movement module up and down, and the horizontal movement module is moved horizontally during brushing, and the adjusting seat, the base plate and the brushing component move up and down synchronously with the change in the height of the upper surface of the sample.

[0010] Preferably, the adjusting seat is formed with an adjusting groove extending up and down, and the brushing component comprises a brushing plate forming the brushing end from a bottom edge, and a connecting shaft fixed to the brushing plate and slidably connected to the adjusting groove from one end. In the brushing direction, an acute angle is formed between the brushing plate and the upper surface of the sample.

[0011] Specifically, the brushing plate can be adjusted to flip up and down about the center line of the connecting shaft. Here, the brushing angle of the brushing plate can be adjusted according to the inclination angle of the upper surface of the sample, so as to achieve the best brushing effect.

[0012] Preferably, the measuring component comprises a distance measuring probe arranged at the brushing end, and a display module arranged on the horizontal movement module and in communication with the distance measuring probe. Here, the real-time detection of the coating thickness is avoided to avoid deviation.

[0013] Preferably, a horizontally extending first sliding groove is formed on the base, and the transverse moving module is slidingly connected in the first sliding groove. In this way, the operation is facilitated.

[0014] According to another specific implementation and preferred aspect of the present application, a second sliding groove perpendicular to the first sliding groove is further formed on the base, the clamping unit comprises a first clamping component and a second clamping component moving towards each other along the second sliding groove, a positioning backstop is arranged between the first clamping component and the second clamping component, the sample is abutted against the positioning backstop from one end surface and clamped between the first clamping component and the second clamping component from opposite sides. In this way, the positioning accuracy of the sample is high, and the clamping is convenient.

[0015] Preferably, the first clamping component and the second clamping component each comprise a sliding block slidingly connected in the second sliding groove, and a clamping arm arranged on the top of the sliding block, wherein the top surface of the clamping arm is arranged flush with the upper surface of the sample.

[0016] In addition, the clamping arm is pivotally connected to the top of the sliding block and can be adjusted by being flipped up and down. This facilitates the flexible matching of the inclination angle of the clamping arm to the upper surface of the sample at any inclination angle.

On the other hand, the sample with any inclination angle of the surface can be flexibly matched, and the operation is simple and convenient. BRIEF DESCRIPTION OF DRAWINGS

[0034] In this example, the clamping unit 2 is movably mounted on the base 1 and forms a clamping area q that matches the sample Y. When clamping, the upper surface of the sample Y is flush with the top of the clamping area q or protrudes upward from the top of the clamping area q.

[0035] In some embodiments, the clamping unit 2 comprises a first clamping component 21 and a second clamping component 22 moving towards each other along the second sliding groove c2, and a positioning abutting grid 23 arranged between the first clamping component 21 and the second clamping component 22, wherein a clamping area q is formed between the first clamping component 21, the second clamping component 22 and the positioning abutting grid 23, and the sample Y is abutted against the positioning abutting grid 23 from one end surface and clamped between the first clamping component 21 and the second clamping component 22 from opposite sides.

That is, the film thickness of the present embodiment is the vertical distance between the brushing end portion d and the upper surface of the sample Y, or the film thickness is the sum of the vertical distance between the brushing end portion d and the surface of the base plate 32 and the thickness of the base plate 32.

[0039] In some embodiments, the adjusting component 33 comprises an adjusting seat 330 and a horizontal movement module 331 movably connected to the base 1 along the horizontal direction, wherein the brushing component 30 is connected to the adjusting seat 330 and can be adjusted to be arranged up and down, and the base plate 32 is rotatably connected to the adjusting seat 330 about a horizontal axis. In this way, the adjustment is convenient, and based on the base plate and the brushing component being connected to the same adjusting seat, the stability of the relative position between the base plate and the brushing end portion is ensured, and the control accuracy of the film thickness is improved.

[0040] Meanwhile, the horizontal moving module 331 is slidingly connected in the first sliding groove c1, and the adjusting seat 330 is movably connected on the horizontal moving module 331, when brushing, the horizontal moving module 331 is moved horizontally, and the adjusting seat 330, the base plate 32 and the brushing component 30 are synchronously moved up and down with the change of the height of the upper surface of the sample.

[0041] In order to further facilitate the implementation, the horizontal moving module 331 is formed with a guide groove c3 extending upward and downward, and the adjusting seat 330 is slidingly connected in the guide groove c3; the adjusting seat 330 is formed with an adjusting groove c4 extending upward and downward, and the brushing component 30 comprises a brushing plate 300 formed with a brushing end d from a bottom edge, and a connecting shaft 301 fixed with the brushing plate 300 and slidingly connected in the adjusting groove c4 from one end, wherein the connecting shaft 301 adopts a bolt.

Here, the brushing angle of the brushing plate can be adjusted according to the inclination angle of the upper surface of the sample, so as to achieve the best brushing effect.

[0043] In addition, the measuring component 31 comprises a distance measuring probe arranged at the brushing end d, and a display module 310 arranged on the horizontal moving module 331 and connected with the distance measuring probe. Here, the real-time detection of the coating thickness avoids deviation.

[0044] In summary, after the brushing device is adopted, the sample is clamped in the clamping area and kept with the upper surface of the sample flush with the top of the clamping area or protruding out of the clamping area, and the brushing starting position of the upper surface of the sample is coated with paint; then the base plate is adjusted to be attached to the upper surface of the sample as a reference, the vertical distance between the brushing end and the surface of the base plate or / and the upper surface of the sample is adjusted by the measuring component to determine the coating thickness, and in the orthographic projection of the upper surface of the sample, the base plate is located in the to-be-coated film area and the brushing end is located in the coated film area; then the brushing end and the base plate are kept relatively fixed and synchronously moved to flatten the paint, and the coating of the upper surface of the sample is completed.
