Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint inspection, in particular to a sampling device for inspecting the adhesion of water-based paint. Background Art

[0002] Water-based paint is a type of paint that uses water as a diluent and does not contain organic solvents. Its construction method is simple and convenient. It is an environmentally friendly paint with a full paint film that looks crystal clear and flexible. In addition, it is also excellent in waterproofness. In the production process of water-based paint, it is necessary to test its adhesion effect on different walls;

[0003] Publication No. CN220136709U discloses a sampling device for water-based paint inspection, which facilitates simultaneous sampling of multiple groups of samples by coordinating multiple groups of drop buckets, sealing balls, first spring shunt tubes and sampling tubes.

[0004] However, the above-mentioned sampling device for water-based paint still has the following problems during actual use: although the sealing effect of the sampling device after sampling is achieved through the sealing mechanism, the opening and closing of the actual sealing device requires manual operation from the bottom. At the same time, due to factors such as static standing, some precipitated paint particles and impurities remain inside the water-based paint, which cannot be effectively discharged after being absorbed by the sampling device. Long-term accumulation causes blockage at the outlet of the sampling device, thereby affecting the normal use of the sampling device.

[0005] Therefore, we propose a sampling device for testing the adhesion of water-based paint in order to solve the above-mentioned problems. Utility Model Content

[0030] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problem that the sealing mechanism of the existing sampling device body 1 cannot be opened conveniently, the present embodiment adopts the following technical scheme: a sampling device for testing the adhesion of water-based paint, comprising a device body 1, and a sampling cavity 2 opened inside the device body 1; a sampling slide rod 3 is slidably arranged in the sampling cavity 2 inside the device body 1, and the top end of the sampling slide rod 3 is penetrated and arranged outside the top surface of the device body 1; the overall device body 1 is distributed in a cylindrical structure, and the bottom end of the device body 1 is arranged in a closed cone shape, and a sealing top cover 6 is fixedly arranged at the top of the device body 1; the upper end of the sampling slide rod 3 is slidably connected with the sealing top cover 6 at the top of the device body 1, and a negative pressure suction disc 7 is fixedly arranged at the bottom end of the sampling slide rod 3 inside the device body 1, and the negative pressure suction disc 7 and the inner wall of the device body 1 are fitted and connected with each other, and the negative pressure suction disc 7 is driven to rise by the sampling slide rod 3, so that the water-based paint can be negatively extracted through the bottom end of the device body 1;

[0032] A sealing mechanism is provided below the sampling cavity 2 inside the device body 1, and the sealing mechanism includes a sealing ball 17, and the sealing ball 17 is slidably arranged at the bottom of the sampling cavity 2; the sealing ball 17 included in the sealing mechanism is sealed inside the bottom end of the device body 1, and the left and right sides of the bottom end of the sealing ball 17 are fixedly connected to the bottom end of the bracket slide rod 8, and the middle parts of the left and right bracket slide rods 8 are slidably arranged on the left and right sides of the outside of the device body 1 through the resistance spring 9;

[0033] The sealing mechanism includes an unlocking ring 10, and the unlocking ring 10 is sleeved on the outside of the device body 1, and the bottom surface of the unlocking ring 10 is fixedly connected to the top of the left and right bracket slide bars 8, and the lifting of the unlocking ring 10 drives the bracket slide bars 8 and the sealing ball 17 to move to the inside of the device body 1 to open the sampling;

[0034] like Figure 1-Figure 3 As shown, when it is necessary to sample the water-based paint through the device body 1, first grasp the device body 1 so that its bottom end enters the water-based paint, and then manually slide the unlocking ring 10 sleeved on the outer wall of the device body 1 upward, so that it drives the bracket slide rods 8 on the left and right sides of the bottom surface to move upward and squeeze the resistance spring 9, and at the same time, the bottom end of the bracket slide rod 8 drives the fixedly connected sealing ball 17 to slide upward inside the device body 1, thereby opening the resistance-sealed sampling cavity 2, so as to perform subsequent sampling operations for the water-based paint;

[0035] Furthermore, the top of the sampling slide rod 3 at the top of the device body 1 is manually grasped and the sampling slide rod 3 is lifted upward, and the bottom end of the sampling slide rod 3 inside the sampling cavity 2 drives the fixedly connected negative pressure suction disc 7 to slide upward in contact with the inside of the sampling cavity 2, and the water-based paint is extracted by negative pressure through the device body 1 with the bottom open, so that the water-based paint enters the device body 1 to complete the extraction work;

[0036] At the same time, after the water-based paint enters the interior of the device body 1, the unlocking ring 10 is manually loosened, so that the bracket slide rod 8, whose bottom end is in a relaxed state, descends under the extension of the resistance spring 9, so that the bottom end of the bracket slide rod 8 drives the fixedly connected sealing ball 17 to re-block the bottom end of the device body 1, thereby preventing the water-based paint inside the device body 1 from overflowing.

[0037] Embodiment 2: In order to solve the problem that the particles and impurities of the water-based paint inside the existing sampling device body 1 affect the discharge, this embodiment adopts the following technical scheme, wherein a sampling guide groove 4 is opened in the front of the device body 1, and a plug-in mechanism is arranged inside the sampling guide groove 4, and the plug-in mechanism includes a debris removal pipeline 5; the sampling cavity 2 inside the device body 1 and the sampling guide groove 4 opened in the front are interconnected; the debris removal pipeline 5 included in the plug-in mechanism and the sampling guide groove 4 are threadedly connected, and a debris removal grid 11 is fixedly arranged inside the debris removal pipeline 5, and a debris removal brush rod 12 is arranged at the rear of the debris removal grid 11 through a bearing to rotate, and when the water-based paint flows through the debris removal pipeline 5, the debris removal grid 11 and the debris removal brush rod 12 are used to filter and remove impurities;

During the circulation of the water-based paint, the impurity removal grid 11 arranged inside the impurity removal pipe 5 is used for filtering so as to filter out the particulate matter and impurities inside the water-based paint. At the same time, the circulation of the water-based paint drives the impurity removal brush rod 12 arranged inside the impurity removal grid 11 to rotate so as to clean the filtered impurities and particles to prevent blockage from affecting the subsequent flow of the water-based paint.
