Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to a sampling tube for random inspection of paint production. Background Technology

[0002] In the production, storage and quality testing of coating products, accurate sampling of coating samples is a key link to ensure the reliability of test results. To meet the sampling needs in different scenarios, various coating sampling devices have emerged.

[0003] Chinese utility model patent CN220772676U discloses a sampling device for spot testing of coating products. The device includes a sampling body with multiple evenly distributed water inlets on its surface. A plastic disc is fixedly connected to one end of the sampling body. A fixing block is fixedly installed in the middle of one side of the plastic disc. A circular pen is movably connected inside the fixing block. Multiple evenly distributed pistons are fixedly installed on the surface of the circular pen, each piston corresponding to one of the multiple water inlets. Sealing rings are fixedly installed on the surface of each piston, and a suction cup is fixedly installed on one side of each piston. All pistons are located inside the sampling body. This utility model provides a sampling device for spot testing of coating products. By using pistons inside the sampling body to divide multiple sampling spaces, the device can extract samples at different heights, improving sample accuracy. The small, needle-shaped sampling device is easy for users to carry, increasing its usability.

[0004] When the existing sampling device is used to extract a sample from the coating, a large amount of residual coating will inevitably adhere to its outer surface due to the adhesiveness of the coating itself. This residual coating will cause sample loss, and the residual coating can easily contaminate the operator's hands, clothing or storage environment. Therefore, it is not convenient to clean the residual coating.

[0005] To address this issue, the present invention provides a sampling tube for random inspection of coating production. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a sampling tube for paint production inspection, which solves the aforementioned problems.

[0007] To solve the above-mentioned technical problems, this utility model provides a sampling tube for paint production sampling inspection, including a base. An adjustment mechanism is fixedly connected to the upper surface of the base, and a sampling mechanism is threadedly connected to the outer surface of the adjustment mechanism. The adjustment mechanism includes a fixed frame fixedly connected to the upper surface of the base. A movable plate is slidably connected to the outer surface of the inner wall of the fixed frame. An externally threaded tube is fixedly connected to the lower surface of the movable plate. The sampling mechanism includes a sampling cylinder threadedly connected to the outer surface of the externally threaded tube. A piston is slidably connected to the inner wall of the sampling cylinder. A rack is fixedly connected to the upper surface of the piston, and a gear is meshed with the outer surface of the rack.

[0008] Furthermore, the sampling mechanism also includes a rubber scraper fixedly connected to the upper surface of the movable plate, and a second motor is fixedly connected to the outer surface of the rubber scraper, with the output shaft of the second motor fixedly connected to the outer surface of the gear.

[0009] By adopting the above technical solution, the output shaft of the second motor is started, which drives the gear to rotate. The rotation of the gear drives the rack rod to move up and down, thereby facilitating the adjustment of the piston height.

[0010] Furthermore, a fixed pipe is fixedly connected to the outer surface of the base, the inner wall of the fixed pipe is slidably connected to the outer surface of the sampling tube, and the inner wall of the fixed pipe is provided with internal threads, and the outer surface of the sampling tube is engraved with scale lines.

[0011] By adopting the above technical solution, the sampling tube can be limited by the fixed pipe, allowing the sampling tube to slide along the inner wall of the base, and the descent depth of the sampling tube can be easily read by the scale lines.

[0012] Furthermore, a storage cylinder is threadedly connected to the inner side of the internal thread, a fixing ring is provided below the storage cylinder, the outer surface of the fixing ring is fixedly connected to the outer surface of the base, a rubber scraper is fixedly connected to the lower surface, and the outer surface of the rubber scraper is slidably connected to the outer surface of the sampling cylinder.

[0013] By adopting the above technical solution, the storage cylinder is threaded to the outer surface of the internal thread, which facilitates the pushing of the coating in the sampling cylinder into the storage cylinder, and the coating adhering to the surface of the sampling cylinder is easily scraped off by the rubber scraper.

[0014] Furthermore, a first motor is fixedly connected to the upper surface of the fixed frame, and a threaded rod is fixedly connected to the output shaft of the first motor. The lower end of the threaded rod is rotatably connected to the inner wall of the fixed frame, and the outer surface of the threaded rod is threadedly connected to the outer surface of the movable plate.

[0015] By adopting the above technical solution, the output shaft of the first motor is started, which drives the threaded rod to rotate. The rotation of the threaded rod causes the moving plate to move along the outer surface of the fixed frame, thereby facilitating the adjustment of the height of the moving plate.

[0016] Furthermore, a battery power supply module is fixedly connected to the outer surface of the fixed frame, a handle is fixedly connected to the upper surface of the battery power supply module, and a control panel is fixedly connected to the outer surface of the battery power supply module.

[0017] The above technical solution allows for easy power supply to the control panel, the first motor, and the second motor via a battery power module, and facilitates the transport of the base via a handle.

[0018] Compared with the prior art, the present invention has the following main advantages:

[0019] 1. This convenient sampling tube for paint production inspection uses a first motor to drive a threaded rod to rotate, which in turn drives the moving plate and sampling cylinder to rise and fall precisely. Combined with the scale lines on the surface of the sampling cylinder, the depth into the paint container can be precisely controlled. At the same time, a second motor drives a piston to move and create negative pressure to complete the sampling. It can flexibly collect paint samples at different depths, meet the needs of layered testing, and improve the sampling accuracy.

[0020] 2. This sampling tube facilitates random inspection of paint production. After sampling, during the upward movement of the sampling cylinder, the rubber scraper on the lower surface of the moving plate will slide closely against its outer surface, which can quickly scrape off the paint adhering to the cylinder wall. In addition, the sampling cylinder is connected to the external threaded pipe. After unscrewing, the sampling cylinder and piston can be thoroughly cleaned separately. The operation is simple and avoids residual paint from contaminating the next sampling. Attached Figure Description

[0034] Example 2

[0035] Reference Figures 1 to 4 In one aspect of this embodiment, a first motor 203 is fixedly connected to the upper surface of the fixed frame 207, and a threaded rod 204 is fixedly connected to the output shaft of the first motor 203.

[0037] In this embodiment, after sampling is completed, during the upward movement of the sampling cylinder 307, the rubber scraper 310 on the lower surface of the moving plate 205 will slide close to its outer surface, which can quickly scrape off the paint adhering to the cylinder wall. The sampling cylinder 307 is threadedly connected to the external threaded tube 206. After unscrewing, the sampling cylinder 307 and the piston 308 can be thoroughly cleaned separately. The operation is simple and avoids residual paint from contaminating the next sampling.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] Working principle:

[0040] When using this paint sampling device, firstly, the storage cylinder 302 needs to be unscrewed from the internal thread 309 of the fixed pipe 301. Then, by holding the handle 202, the base 1 is moved above the paint bucket to be sampled, and the sampling cylinder 307 is aligned with the opening of the paint bucket. After preparation, the first motor 203 is started through the control panel 4. The output shaft of the first motor 203 drives the threaded rod 204 to rotate. Under the threaded engagement between the threaded rod 204 and the moving plate 205, the moving plate 205 slides downward along the inner wall of the fixed frame 207, while simultaneously driving the external threaded pipe 206 and its threaded connection. The sampling cylinder 307 moves downwards synchronously. The operator can precisely control the depth of the sampling cylinder 307 within the paint container by observing the scale lines on its outer surface, thus meeting the needs for collecting paint samples at different depths. Once the sampling cylinder 307 reaches the target depth, the second motor 304 is activated again via the control panel 4. The output shaft of the second motor 304 drives the gear 306 to rotate. Since the gear 306 meshes with the rack 305, the rotation of the gear 306 causes the rack 305 to move upwards, thereby pulling the piston 308 to slide upwards along the inner wall of the sampling cylinder 307. At this point, the sample is taken... A negative pressure is created inside the sample cylinder 307, and the paint is drawn into the cylinder through the lower opening of the sampling cylinder 307 to complete the sampling. After sampling, the first motor 203 is started in reverse to move the moving plate 205 to drive the sampling cylinder 307 to return to its original position. During this process, the rubber scraper 310 fixedly connected to the lower surface of the moving plate 205 slides against the outer surface of the sampling cylinder 307 to scrape off the excess paint adhering to the cylinder wall, avoiding contamination of the device or loss of the sample. Afterward, the storage cylinder 302 is screwed back into the internal thread 309 of the fixed pipe 301. At this time, the storage cylinder 302 and the fixed pipe 301 are closed due to the screw thread. The threaded connection has a tiny gap, which can balance the air pressure. Then, the second motor 304 is started in reverse, which causes the rack rod 305 to drive the piston 308 downward. The thrust of the piston 308 pushes the coating in the sampling cylinder 307 through the gap into the storage cylinder 302, realizing the transfer and storage of the sample. If the sampling device needs to be cleaned, simply rotate the sampling cylinder 307 to separate it from the external threaded tube 206, and the sampling cylinder 307 and piston 308 can be removed separately for cleaning. The entire operation is powered by the battery power module 201, ensuring that the device can operate stably without an external power source.

[0041] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
