Description

Technical Field

[0001] This utility model relates to the field of materials science and technology, specifically to a coating testing and sampling device. Background Technology

[0002] Sampling is a crucial step in the paint production process. By sampling the paint, we can test various performance indicators such as color, viscosity, drying properties, and weather resistance, thereby ensuring that the product quality meets relevant standards. At the same time, sampling also helps to identify problems that occur in the paint production process in a timely manner, so that process parameters can be adjusted promptly.

[0003] However, when sampling existing paints using sampling devices, a single pipette-like sampling structure is typically inserted directly into the paint can. When the paint in the can separates due to prolonged stillness, multiple samplings of the separated samples are required, making paint sampling cumbersome and time-consuming. In addition, existing paints generally need to be taken to a laboratory for testing after sampling. If the paint sample cannot be taken for testing in time, the existing sampling device cannot seal and preserve the paint sample, resulting in the sample becoming unusable due to oxidation upon entering the air, causing unnecessary waste of paint samples. Utility Model Content

[0004] The purpose of this invention is to provide a coating testing and sampling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paint testing and sampling device, comprising a base, a high-frequency vibration table provided on one side of the top of the base, a groove provided on the top of the high-frequency vibration table, a paint sample container placed inside the groove, a support provided on the top of the high-frequency vibration table, an electric push rod installed on the top of the support, a locking block fixedly connected to the output end of the electric push rod, multiple sampling tubes penetrating the bottom end of the locking block, a connecting hose penetrating one side wall of the locking block, a vertical tube sleeved at the end of the connecting hose, a first solenoid valve provided in the middle of the vertical tube, a storage tank sleeved at the bottom end of the vertical tube, a horizontal tube penetrating one side of the top of the storage tank, a third solenoid valve provided at the connection between the horizontal tube and the storage tank, a nitrogen tank provided at the end of the horizontal tube away from the storage tank, a sample outlet tube penetrating the bottom of the storage tank, and a miniature negative pressure pump provided at the top of the storage tank.

[0011] Preferably, the interior of the nitrogen tank is connected to the interior of the storage tank via a horizontal pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This paint testing and sampling device, through the setting of a high-frequency vibration table, groove, clamping block and sampling tubes, when it is necessary to sample the paint in the tank, the tank containing the paint is placed in the groove, and the high-frequency vibration of the high-frequency vibration table mixes the paint in the tank, reducing the probability of paint stratification in the tank. Then, multiple sampling tubes of different lengths are simultaneously inserted into the tank to take samples, so that the sampling tubes can simultaneously sample paint at different depths, eliminating the need for multiple sampling steps, thus saving the sampling time.

[0014] 2. This paint testing and sampling device, through the installation of a third solenoid valve, a horizontal pipe, a nitrogen tank, and a micro negative pressure pump, allows the storage tank for holding paint samples within the sampling device to first expel the air inside with nitrogen. Then, when the paint sample is drawn into the storage tank, the nitrogen inside the storage tank is expelled again, allowing the paint sample in the storage tank to be sealed by nitrogen. This facilitates the sealed preservation of paint samples by this sampling device, reduces the probability of paint samples being oxidized due to air entering, and reduces unnecessary waste of paint samples.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4As shown, the paint testing and sampling device of this embodiment includes a base 1. A high-frequency vibration table 2 is provided on one side of the top of the base 1. A groove 3 is provided on the top of the high-frequency vibration table 2. A paint sample container 19 is placed inside the groove 3. A bracket 4 is provided on the top of the high-frequency vibration table 2. An electric push rod 7 is installed on the top of the bracket 4. A locking block 6 is fixedly connected to the output end of the electric push rod 7. Multiple sampling tubes 5 pass through the bottom end of the locking block 6. A connecting hose 8 passes through one side wall of the locking block 6. A vertical tube 10 is sleeved at the end of the connecting hose 8. A first solenoid valve 9 is provided in the middle of the vertical tube 10. A storage tank 11 is sleeved at the bottom end of the vertical tube 10. A horizontal tube 17 passes through one side of the top of the storage tank 11. A third solenoid valve 16 is provided at the connection between the horizontal tube 17 and the storage tank 11. A nitrogen tank 18 is provided at the end of the horizontal tube 17 away from the storage tank 11. A sample outlet tube 13 passes through the bottom of the storage tank 11. A micro negative pressure pump 14 is provided at the top of the storage tank 11.

[0024] Specifically, the high-frequency vibration table 2 drives the paint sample container 19 placed in the groove 3 to generate high-frequency vibration, thereby achieving uniform mixing of the paint inside the paint sample container 19. The groove 3 facilitates the stable placement of the paint sample container 19 on the high-frequency vibration table 2, allowing the paint sample container 19 to smoothly mix the paint inside. Before sampling, a circular hole is made in the paint sample container 19, and the inner diameter of the circular hole matches the outer diameter of the clamping block 6, allowing the clamping block 6 to smoothly insert the sampling tube 5 into the interior of the paint sample container 19, enabling the sampling tube 5 to sample the paint. The electric push rod 7 can change the height of the clamping block 6 and the sampling tube 5. Multiple sampling tubes 5 have the same diameter but are located at different positions at the bottom of the clamping block 6, and the lengths of the multiple sampling tubes 5 are different, making... The sampling tube 5 can penetrate into the paint at different depths to take samples, thus avoiding multiple sampling steps and saving sampling time. The vertical tube 10 connects the hose 8 to the inside of the storage tank 11. The first solenoid valve 9 can open and close the vertical tube 10. The inner wall of the storage tank 11 is also equipped with a glass inner layer, so that the paint does not easily react with the outer wall of the storage tank 11. The horizontal tube 17 connects the storage tank 11 to the nitrogen tank 18. The third solenoid valve 16 can control the opening and closing of the horizontal tube 17. The nitrogen tank 18 is filled with high-purity nitrogen. The sample outlet tube 13 is used to remove the paint sample from the storage tank 11. The micro negative pressure pump 14 is used to expel the air in the storage tank 11 and simultaneously draw in nitrogen and liquid paint samples.

[0025] Furthermore, the bottom end of the bracket 4 is fixedly connected to the base 1, and the paint sample container 19 is embedded and connected to the high-frequency vibration table 2 through the groove 3. The bracket 4 has a "U-shaped structure", and a horizontal support structure can be added to the inside, so that the paint sample container 19 can maintain a relatively stable state on the high-frequency vibration table 2, which is conducive to the subsequent sampling tube 5 to sample the paint in the paint sample container 19.

[0026] Furthermore, the card block 6 has an internal cavity, and the sampling tube 5 communicates with the inside of the card block 6 through the cavity. The storage tank 11 is connected to the inside of the card block 6 through the connecting hose 8, so that the sampling tube 5 can be used by the micro negative pressure pump 14 to expel the air in the storage tank 11, and at the same time, the sampling tube 5 is sucked into the storage tank 11 through the connecting hose 8 for temporary storage.

[0027] Furthermore, an exhaust pipe 15 extends through the top of the storage tank 11, the outlet of the micro negative pressure pump 14 is connected to the bottom of the exhaust pipe 15, and the inlet of the micro negative pressure pump 14 is connected to the interior of the storage tank 11, so that the air inside the storage tank 11 can be discharged, thereby reducing the probability of the paint sample inside the storage tank 11 being oxidized.

[0028] Furthermore, a micro oxygen sensor 20 is installed on the inner wall of the air inlet of the micro negative pressure pump 14. The micro oxygen sensor 20 is electrically connected to the third solenoid valve 16. The micro oxygen sensor 20 is a sensor used to detect low concentrations of oxygen. It can detect the oxygen concentration in the storage tank 11 so as to realize the linkage control of the third solenoid valve 16.

[0029] Furthermore, a second solenoid valve 12 is provided in the middle of the sample outlet tube 13. The sample outlet tube 13 is connected to the interior of the storage tank 11, which can control the opening and closing of the sample outlet tube 13, thereby facilitating the orderly removal of the paint sample from the storage tank 11.

[0030] Furthermore, the interior of the nitrogen tank 18 is connected to the interior of the storage tank 11 through the horizontal pipe 17. Nitrogen can be drawn into the storage tank 11 under the action of the micro negative pressure pump 14, thereby facilitating the sealing and protection of the paint sample in the storage tank 11.

[0031] The method of using this embodiment is as follows: When using this paint testing and sampling device, first connect the device to an external power supply, then make a round hole at the top of the paint sample container 19 to be sampled that matches the outer diameter of the locking block 6, then place the paint sample container 19 on the groove 3 of the high-frequency vibration table 2, and then start the high-frequency vibration table 2 so that the paint sample container 19 can generate high-frequency vibration, which promotes the paint in the paint sample container 19 to be mixed evenly. Then, start the electric push rod 7 so that the electric push rod 7 pushes the locking block 6 down, so that the locking block 6 drives multiple sampling tubes 5 to simultaneously extend into the paint sample container 19. Then, start the micro negative pressure pump 14 and the third solenoid valve 16. At this time, the micro negative pressure pump 14 discharges the air in the storage tank 11 through the exhaust pipe 15, and at the same time... Nitrogen gas in nitrogen tank 18 is transferred to storage tank 11 via horizontal pipe 17, displacing air from storage tank 11. When the micro oxygen sensor 20 inside storage tank 11 can no longer detect oxygen in the air, the micro sensor will control the third solenoid valve 16 to close, and then the first solenoid valve 9 will open. At this time, nitrogen gas in storage tank 11 will be discharged, and the paint sample will be sucked into the card block 6 through sampling tube 5, and then enter the vertical pipe 10 through connecting hose 8. After that, it enters storage tank 11 through vertical pipe 10 for storage. After the paint sampling is completed, the first solenoid valve 9 and the micro negative pressure pump 14 will be closed. At this time, the top inside storage tank 11 will be sealed with nitrogen gas, so that the paint sample in storage tank 11 is sealed and preserved.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
