Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to a sampling device for a film-forming agent mixing tank. Background Technology

[0002] In the production and preparation of film-forming agents, the mixing process is a crucial step that determines the uniformity of product quality. As a substance capable of forming a continuous thin film on a substrate surface, the uniform distribution of the film's components directly affects key indicators such as the film's mechanical properties, adhesion, and corrosion resistance. Therefore, during and after mixing, samples of the film-forming agent in the mixing tank must be taken for testing. By analyzing parameters such as the component ratio, viscosity, and solid content of the samples, it can be determined whether the mixing effect meets the process requirements. Because the flow state of the film-forming agent in the mixing tank is affected by factors such as stirring rate, tank structure, and material viscosity, uneven mixing may occur at different depths. For example, in the initial stage of stirring, the material in the upper layer of the tank may not have fully mixed with the material in the lower layer, or the composition at the bottom may differ from that at the top due to material settling. If samples are taken from only a single depth, the obtained samples cannot fully reflect the overall mixing state of the materials in the tank, which may lead to distorted test results, thereby affecting the judgment and adjustment of the production process and increasing the risk of producing unqualified products. In existing technologies, sampling devices for film-forming agent mixing tanks are mostly fixed-depth sampling structures, meaning the insertion length of the sampling tube is fixed, and samples can only be collected from a specific depth inside the tank. If samples at different depths are required, it is often necessary to disassemble the device multiple times, adjust the length of the sampling tube, and reinstall it. This operation is cumbersome and time-consuming, which not only affects production efficiency but may also increase the risk of contamination due to frequent disassembly causing the material inside the tank to come into contact with the outside environment.

The first motor is mounted on the side wall of the first housing, and the output end of the first motor is fixedly connected to the bidirectional screw.

[0008] Furthermore, the first rotating mechanism includes a first cavity, a second bevel gear, and a driving mechanism.

[0012] The beneficial effects of the embodiments of this utility model are as follows: 1.

[0021] like Figures 1-6 As shown, a sampling device for a film-forming agent mixing tank according to an embodiment of the present invention is used to sample the film-forming agent in the tank 1. The device includes a first housing 2, which is fixedly disposed on the top side wall of the tank 1. It also includes a movable port 3, a movable block 4, a second housing 5, a position adjustment mechanism, and a sampling mechanism. The movable port 3 is provided through the first housing 2. The movable block 4 is provided through and slidably disposed in the movable port 3. The second housing 5 is fixedly disposed at the bottom end of the movable block 4. A sampling port 6 is provided at the bottom end of the second housing 5. An electronic control valve is disposed in the sampling port 6. The position adjustment mechanism is disposed in the first housing 2 for adjusting the position of the movable block 4. The sampling mechanism is disposed on one side of the tank 1 for sampling the film-forming agent in the tank 1.

[0022] Reference Figures 1-4 The sampling mechanism includes a glass bottle 7 and a blower 9. The glass bottle 7 is located on one side of the tank body 1. A sampling tube 8 is connected to and fixedly installed at the top of the glass bottle 7. The end of the sampling tube 8 away from the glass bottle 7 passes through the moving block 4 and extends into the second housing 5. The blower 9 is located at one end of the glass bottle 7. The input end of the blower 9 is connected to the glass bottle 7, and the output end of the blower 9 is connected to the external environment. Specifically, when the second housing 5 is extended into the tank body 1, the operation of the blower 9 can generate negative pressure in the glass bottle 7. Then, the film-forming agent can be allowed to enter the second housing 5 by opening the electronic control valve, and then enter the glass bottle 7 through the sampling tube 8, thus facilitating the sampling of the film-forming agent.

[0023] Reference Figure 5 and Figure 6 The position adjustment mechanism includes an adjustment frame 10, an adjustment wheel 11, a first rotation mechanism, and a relative movement mechanism. U-shaped adjustment frames 10 are slidably arranged on both sides of the moving block 4 within the first housing 2. The adjustment wheel 11 is rotatably disposed within the adjustment frame 10. The first rotation mechanism is disposed within the first housing 2 to drive the adjustment wheel 11 to rotate. The relative movement mechanism is disposed within the first housing 2 to drive the two adjustment frames 10 to move relative to each other. The relative movement mechanism includes a bidirectional screw 12 and a first motor 13. The bidirectional screw 12 is rotatably disposed within the first housing 2 and passes through the two adjustment frames 10 via a threaded connection. The first motor 13 is mounted on the side wall of the first housing 2, and its output end is fixedly connected to the bidirectional screw 12. Specifically, after the moving block 4 is inserted into the moving opening 3, the operation of the first motor 13 drives the bidirectional screw 12 to rotate. This, in turn, through the threaded connection between the bidirectional screw 12 and the adjustment frame 10, drives the adjustment frame 10 and the adjustment wheel 11 to move. The adjustment wheel 11 then clamps the moving block 4, thereby achieving the installation of the moving block 4.

[0024] Reference Figure 5 and Figure 6The first rotating mechanism includes a first cavity 14, a second bevel gear 16, and a driving mechanism. The adjusting frame 10 has a first cavity 14 located on one side of the adjusting wheel 11. A first bevel gear 15 is rotatably mounted on the side wall of the first cavity 14. A connecting rod is fixedly mounted between the first bevel gear 15 and the adjacent adjusting wheel 11. The second bevel gear 16 is rotatably mounted on the side wall of the first cavity 14 and meshes with the first bevel gear 15. The driving mechanism is mounted on the adjusting frame 10 and is used to drive the second bevel gear 16 to rotate. The driving mechanism includes a driving prism 17 and a second motor 18. The driving prism 17 is rotatably mounted inside the first housing 2 and passes through the adjusting frame 10 and the second bevel gear 16. The driving prism 17 is slidably connected to the second bevel gear 16. The second motor 18 is mounted on the side wall of the first housing 2. The output end of the motor 18 is fixedly connected to the drive prism 17. The adjustment frame 10 is provided with a first drive port 19, and the second bevel gear 16 is provided with a second drive port. The drive prism 17 connects the first drive port 19 and the second drive port. The drive prism 17 is slidably connected to the side wall of the second drive port. The side wall of the adjustment wheel 11 is fixedly provided with an anti-slip pad. Specifically, the operation of the second motor 18 can drive the drive prism 17 to rotate. Thus, the sliding cooperation between the drive prism 17 and the second bevel gear 16 can drive the second bevel gear 16 to rotate. At the same time, the meshing between the second bevel gear 16 and the first bevel gear 15 can drive the first bevel gear 15 and the adjustment wheel 11 to rotate. This facilitates the adjustment of the position of the moving block 4 and the second housing 5 by the friction between the adjustment wheel 11 and the moving block 4, thereby facilitating the adjustment of the sampling depth.

[0025] In this embodiment, during use, after the operator inserts the moving block 4 into the moving port 3, the operation of the first motor 13 drives the bidirectional screw 12 to rotate. The bidirectional screw 12, through its threaded engagement with the adjusting frame 10, moves the adjusting frame 10 and the adjusting wheel 11, which in turn clamps the moving block 4. Then, the operation of the second motor 18 drives the drive prism 17 to rotate. This, through the sliding engagement between the drive prism 17 and the second bevel gear 16, rotates the second bevel gear 16. Simultaneously, the second bevel gear... The meshing of wheel 16 with the first bevel gear 15 drives the first bevel gear 15 and the adjusting wheel 11 to rotate, thereby facilitating the adjustment of the position of the moving block 4 and the second housing 5 by the friction between the adjusting wheel 11 and the moving block 4, thus facilitating the adjustment of the sampling depth. Afterwards, the operator opens the electronic control valve and controls the fan 9 to work. The operation of the fan 9 can generate negative pressure in the glass bottle 7, which allows the film-forming agent to enter the second housing 5 through the sampling port 6, and then enter the glass bottle 7 through the sampling tube 8, thus facilitating the sampling of the film-forming agent.
