Description

Technical Field

[0001] This utility model relates to the field of coating testing technology, and in particular to a device for testing the viscosity of water-based coatings. Background Technology

[0002] In the field of coating performance testing, the viscometer is the core equipment used to determine the viscosity of coating samples. Existing viscometer technologies include... Figure 1 As shown, the device includes a base 1, a cylindrical column 2 vertically fixed to the upper surface of the base 1, a main unit 3 slidably connected to the upper section of the cylindrical column 2, an upper connecting block 4 and a lower connecting block symmetrically arranged on the rear end face of the main unit 3 near the cylindrical column 2, and both connecting blocks are sleeved on the outer periphery of the cylindrical column 2; a viscosity detection paddle 6 is installed at the rotor end below the main unit 3; a lifting handle 5 is provided on the side of the main unit 3, and the lifting handle 5 is used to drive the main unit 3 to rise and fall along the cylindrical column 2.

[0003] The base 1 is also provided with a material holding component 7, which includes a pad and a material holding container. The pad is fixed to the upper surface of the base 1 and located directly below the viscosity testing paddle 6. Its upper surface is provided with a groove adapted to the material holding container. The material holding container is used to hold the coating sample to be tested.

[0004] In actual testing, the operation process consists of three steps: First, the container containing the paint sample is embedded into the groove of the pad to complete the positioning; then, the lifting handle 5 is pressed down, and the main unit 3 drives the viscosity testing paddle 6 to descend synchronously until the testing paddle 6 is completely immersed in the paint sample for viscosity measurement; after the test is completed, the lifting handle 5 is raised to make the main unit 3 rise back, the viscosity testing paddle 6 is removed from the container, and finally the container is removed from the groove to complete a single test.

[0005] However, existing viscometers have a problem with dirt residue during coating testing. Specifically, because the coating itself is viscous, residual coating will adhere to the surface of the viscosity testing paddle 6 when it leaves the container. After the container is removed, the residual coating that did not drip off the viscosity testing paddle 6 will drip into the groove of the pad due to gravity. If it is not cleaned in time, the residual coating in the groove will gradually dry and harden, which will not only contaminate the bottom of the container to be placed next, but may also cause the container to tilt, affecting the accuracy of the immersion depth of the viscosity testing paddle 6.

[0006] In summary, designers need to develop an improved viscosity testing device to address the problem of "residual paint dripping - groove contamination - decreased accuracy of subsequent tests" in existing viscometers after testing. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this invention is to provide a water-based coating viscosity testing device to solve the problem of dirt caused by residual coating dripping from the viscosity testing paddle in the prior art.

[0008] The technical solution of this utility model is as follows:

[0009] A water-based coating viscosity testing device includes a base, a column on the upper surface of the base, a main unit slidably connected to the upper section of the column, a connecting block on the rear end of the main unit, and the connecting block being sleeved on the outer periphery of the column; a viscosity testing paddle is provided below the main unit, and a material holding assembly is provided on the upper surface of the base directly below the viscosity testing paddle; a cable (such as a flexible transmission component like a bicycle brake cable) is fixed on the connecting block, and a material receiving mechanism is provided beside the material holding assembly.

[0010] The receiving mechanism includes a guide post on the upper surface of the base, and a receiving frame and a positioning ring are sequentially fitted around its outer periphery from top to bottom. The receiving frame and the guide post are rotatably engaged. A receiving tray is placed on the receiving frame, which is located directly below the viscosity testing paddle or next to the material holding assembly. A first positioning block is provided on the lower surface of the receiving frame, and a second positioning block adapted to the first positioning block is provided on the upper surface of the positioning ring. By rotating the receiving frame, the receiving tray switches between "next to the material holding assembly (avoidance position)" and "directly below the viscosity testing paddle (receiving position)". During testing, it avoids the viscosity testing paddle. After testing, it precisely docks with the testing paddle through the positioning block to receive residual dripping paint.

[0011] The lower section of the column is provided with a first cable support. A tensioned spring is provided between the first cable support and the receiving frame. The receiving frame is linked to the connecting block through the cable. The receiving frame is driven by the lifting power of the main unit. When the main unit descends for detection, the cable pulls the receiving frame to the avoidance position. When the main unit rises, the spring pulls the receiving frame back to the receiving position. No manual operation of the receiving tray is required.

[0012] Furthermore, a second cable bracket is fitted onto the upper end of the column, and a guide fixing groove is provided on the second cable bracket. The end of the cable away from the receiving frame passes through the guide fixing groove and is fixed to the connecting block.

[0013] Furthermore, the guide post sidewall is provided with at least two positioning blind holes spaced apart along the axial direction, and the positioning ring sidewall is provided with a positioning hole through which a clamping screw is threaded into the positioning hole. One end of the clamping screw extending into the positioning hole has a positioning ball, which is embedded in any of the positioning blind holes to adjust and lock the axial height of the positioning ring on the guide post. At the same time, it limits the axial height of the receiving rack. Through preset height adjustment, it is ensured that the receiving tray has completed the switch to the "avoidance position" before the viscosity detection paddle descends, avoiding spatial interference with the detection paddle and ensuring that the detection paddle is smoothly immersed in the coating without the risk of jamming or collision.

[0014] Furthermore, the receiving rack includes an annular bearing support and a guide post sleeve seat. The annular bearing support and the guide post sleeve seat are eccentrically arranged and integrally formed by a connecting bridge. The receiving tray overlaps on the annular bearing support, the guide post sleeve seat is sleeved on the outer periphery of the guide post, and is fixed to the end of the cable away from the connecting block. The first positioning block protrudes from the lower end face of the guide post sleeve seat, and the two ends of the spring are respectively fixed to the connecting bridge and the first cable bracket.

[0015] Furthermore, the receiving tray includes a barrel body with a diameter larger than that of the viscosity testing paddle. The open end of the barrel body extends outward to form a baffle, which overlaps the annular support. The baffle extends outward to form a handle. The barrel body receives residual paint, and the diameter design ensures that the drips fall completely into the barrel. The handle makes it easy to remove and clean. The presence of the receiving tray solves the problem of existing paint residue contaminating the groove of the pad, while reducing the frequency of cleaning.

[0016] Furthermore, the first positioning block is a fan-shaped part facing the center of the guide post sleeve seat. One side of the fan-shaped part has two edge lines, one upper and one lower. The center of the annular bearing support and the center of the guide post sleeve seat form a line. The edge line is parallel to the line. When the first positioning block and the second positioning block abut, the rotation angle range of the guide post sleeve seat around the guide post is limited to 180°~270°, ensuring that the receiving tray is stably stopped in the avoidance position or the receiving position.

[0017] Furthermore, the guide post sleeve has a cable mounting part protruding from the front side wall away from the first cable bracket, and a cable limiting groove is provided on the side wall away from the annular bearing support. The extension direction of the cable limiting groove is consistent with the direction of the cable. The cable mounting part fixes the end of the cable, and the limiting groove constrains the direction of the cable so that it is consistent with the rotation tangent direction of the receiving frame, ensuring that the cable does not detach from the guide post sleeve.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses a receiving tray of a receiving mechanism that automatically rotates to directly below the viscosity testing paddle after testing, accurately catching residual dripping paint, reducing the frequency of manual cleaning, and solving the problem of residual paint contamination affecting subsequent testing.

[0020] 2. This utility model utilizes the lifting power of the main unit to drive the receiving rack to automatically switch positions via cables and springs (avoiding during testing and receiving after testing), eliminating the need for manual adjustment of the receiving tray and improving the automation level of the testing process.

[0021] 3. The cooperation between the first and second positioning blocks in the fan shape of this utility model limits the rotation angle of the receiving frame (180°~270°), and the cable limiting groove and guide bracket ensure the stability of the transmission path, thus guaranteeing the accuracy of the receiving tray in receiving and aligning the viscosity detection paddle.

[0022] 4. The positioning blind hole of the guide column and the positioning ring work together to make the height of the receiving tray adjustable, which can be accurately adapted to the testing scenario according to the height of the container; through preset height adjustment, it is ensured that the receiving tray has completed the switch to the "avoidance position" before the viscosity testing paddle descends, avoiding spatial interference with the testing paddle, ensuring that the testing paddle is smoothly immersed in the coating without the risk of jamming or collision.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] like Figures 1 to 9As shown, a water-based coating viscosity testing device includes a base 1, a column 2 vertically mounted on the upper surface of the base 1, a main unit 3 slidably connected to the upper section of the column 2, and an upper connecting block 4 and a lower connecting block symmetrically mounted on the rear end face of the main unit 3, both of which are sleeved on the outer periphery of the cylindrical column 2; a lifting handle 5 is located beside the main unit 3, which is used to drive the main unit 3 to rise and fall along the cylindrical column 2; a viscosity testing paddle 6 is located below the main unit 3; a material holding assembly 7 is located on the upper surface of the base 1 directly below the viscosity testing paddle 6; a cable 8 (such as a flexible transmission component like a bicycle brake cable) is fixed on the upper connecting block 4; a receiving mechanism 9 is located on the side of the material holding assembly 7 away from the lifting handle 5; the receiving mechanism 9 includes a guide column 9-1 vertically mounted on the upper surface of the base 1, and a receiving frame 9-2 and a positioning ring 9-3 are sequentially mounted on its outer periphery from top to bottom; the receiving frame 9-2 is rotatably engaged with the guide column 9-1; a receiving tray 9-4 is placed on the receiving frame 9-2, which is located directly below the viscosity testing paddle 6 or in a container. Beside the material assembly 7; the lower end face of the receiving rack 9-2 is provided with a first positioning block 9-2.2.1, and the upper end face of the positioning ring 9-3 is provided with a second positioning block 9-3.1 that matches the first positioning block 9-2.2.1; by rotating the receiving rack 9-2, the receiving tray 9-4 switches between "beside the material assembly 7 (avoidance position)" and "directly below the viscosity testing paddle 6 (receiving position)". During testing, it avoids the viscosity testing paddle 6, and after testing, it precisely aligns with the testing paddle 6 through the positioning block to receive residual drips. The coating is applied; the lower section of the column 2 is equipped with a first cable support 10, and a spring 9-5 in a tensioned state is provided between the first cable support 10 and the receiving frame 9-2. The receiving frame 9-2 is linked to the upper connecting block 4 through the cable 8. The lifting power of the host 3 drives the receiving frame 9-2 to move together. When the host 3 is lowered for detection, the cable 8 pulls the receiving frame 9-2 to the avoidance position. When the host 3 is raised, the spring 9-5 pulls the receiving frame 9-2 back to the receiving position. No manual operation of the receiving tray 9-4 is required.

[0035] Furthermore, a second cable bracket 11 is fitted on the upper end of the column 2 away from the base 1. A guide fixing groove is provided on the second cable bracket 11. The end of the cable 8 away from the receiving frame 9-2 passes through the guide fixing groove and is fixed to the connecting block.

[0036] Furthermore, the guide post 9-1 has at least two positioning blind holes 9-1.1 spaced axially on its side wall, and the positioning ring 9-3 has a positioning hole through its side wall. The positioning hole is threaded with a clamping screw 9-3.2. One end of the clamping screw 9-3.2 that extends into the positioning hole has a positioning ball. The positioning ball is embedded in any of the positioning blind holes 9-1.1 to adjust and lock the axial height of the positioning ring 9-3 on the guide post 9-1, while limiting the axial height of the receiving rack 9-2. Through preset height adjustment, it is ensured that the receiving tray 9-4 has completed the switch to the "avoidance position" before the viscosity detection paddle 6 descends, avoiding spatial interference with the detection paddle 6 and ensuring that the detection paddle 6 can smoothly immerse in the coating without the risk of jamming or collision.

[0037] Furthermore, the receiving frame 9-2 includes an annular bearing support 9-2.1 and a guide post sleeve seat 9-2.2. The annular bearing support 9-2.1 and the guide post sleeve seat 9-2.2 are eccentrically arranged and integrally formed by connecting bridge. The receiving tray 9-4 overlaps on the annular bearing support 9-2.1. The guide post sleeve seat 9-2.2 is sleeved on the outer periphery of the guide post 9-1 and fixed to the end of the cable 8 away from the connecting block. The first positioning block 9-2.2.1 protrudes from the lower end face of the guide post sleeve seat 9-2.2. The two ends of the spring 9-5 are fixed to the connecting bridge and the first cable bracket 10, respectively.

[0038] Furthermore, the receiving tray 9-4 includes a barrel body with a diameter larger than that of the viscosity testing paddle 6. The open end of the barrel body extends outward to form a baffle, which overlaps with the annular support 9-2.1. The baffle extends outward to form a handle 9-4.1. The barrel body receives residual paint, and the diameter design ensures that the drips fall completely into the barrel. The handle 9-4.1 facilitates removal and cleaning. The presence of the receiving tray 9-4 reduces the frequency of cleaning residual paint.

[0039] Furthermore, the first positioning block 9-2.2.1 is a fan-shaped part facing the center of the guide post sleeve seat 9-2.2. One side of the fan-shaped part has two edge lines, one upper and one lower. The center of the annular bearing support 9-2.1 and the center of the guide post sleeve seat 9-2.2 form a line, and the edge line is parallel to the line. When the first positioning block 9-2.2.1 abuts against the second positioning block 9-3.1, the rotation angle range of the guide post sleeve seat 9-2.2 around the guide post 9-1 is limited to 180° to 270°, ensuring that the receiving tray 9-4 is stably stopped in the avoidance position or the receiving position.

[0040] Furthermore, the front side wall of the guide post sleeve 9-2.2 away from the first cable support 10 is provided with a cable mounting part 9-2.2.2, and the side wall of the guide post sleeve 9-2.2 away from the annular bearing support 9-2.1 is provided with a cable limiting groove 9-2.2.3. The extension direction of the cable limiting groove 9-2.2.3 is consistent with the direction of the cable 8. The cable mounting part 9-2.2.2 fixes the end of the cable 8, and the limiting groove constrains the direction of the cable 8 so that it is consistent with the rotation tangent direction of the receiving frame 9-2, ensuring that the cable 8 does not detach from the guide post sleeve 9-2.2.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
