Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, specifically to a water-based coating viscosity testing device. Background Technology

[0002] Water-based coatings are environmentally friendly coatings that use water as the main solvent or dispersion medium. They are widely used in building decoration, industrial coating and other fields. Their viscosity directly affects the workability and film quality of the coating. During the coating production process, the viscosity of the coating may fluctuate due to changes in the formula ratio, temperature changes and other factors. Therefore, it is necessary to use a viscosity testing device to test the viscosity of water-based coatings to ensure that the coating products meet the process requirements.

[0003] When testing the viscosity of water-based coatings, the coating must be transferred to a container for testing. However, when testing the viscosity of the coating inside the container, the container is easily touched by the operator, causing it to tilt and splash the coating into the surrounding environment. Therefore, there is an urgent need to develop a water-based coating viscosity testing device to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water-based coating viscosity testing device, which solves the technical problem that containers are easily touched by operators, causing them to tilt and resulting in water-based coatings splashing into the surrounding environment.

[0005] To achieve the above objectives, this utility model provides a water-based coating viscosity testing device through the following technical solution: a support frame, a movable plate is mounted on one side of the top of the support frame via a lifting component, and a viscometer for detecting the viscosity of water-based coatings is fixedly connected to the center of the bottom of the movable plate.

[0006] It also includes an anti-tipping mechanism, which includes two sets of housings set on the top of the movable plate. Inside the housings, a support rod is installed via an elastic component. The support rod is located outside the viscometer. At the bottom of the support rod, an abutment seat for pressing the container storing water-based paint is installed. The support rod passes through the interior of the movable plate. An abutment groove is opened inside the abutment seat, and the cross-section of the abutment seat is semi-circular.

[0007] Preferably, the elastic component includes a spring disposed inside the housing, the bottom end of the spring being fixedly connected to the top end of the support rod, and a limiting bolt extending out of the housing is threaded onto one side of the bottom of the spring.

[0008] Preferably, the lifting assembly includes a motor disposed on one side of the top of the support frame, the output end of the motor passing through one side of the top of the support frame and fixedly connected to a screw, a limiting screw sleeve is threaded on the outer side of the screw, and one end of the limiting screw sleeve passes through one side of the support frame and is fixedly connected to one side of the movable plate.

[0009] Preferably, a protective box is fixedly installed on one side of the support frame, and the protective box is located outside the screw.

[0010] Preferably, the outer side of the support frame is also provided with multiple sets of connecting shafts, and a connector is movably installed on the inner side of the connecting shaft. A threaded foot is installed on the internal thread of one end of the connector.

[0011] Preferably, it also includes a dustproof mechanism, which includes a corrugated pipe disposed at the bottom of the movable plate, and the corrugated pipe is located between the viscometer and the support rod. The bottom end of the corrugated pipe is fixedly connected to a bottom ring, and two sets of movable sleeves are fixedly connected to the outside of the bottom ring. The movable sleeves are located on the outside of the lower end of the support rod, and a locking element is threaded on one side of the movable sleeve.

[0012] This invention provides a device for detecting the viscosity of water-based coatings. Compared with the prior art, it has the following advantages.

[0013] 1. The motor drives the screw to rotate, which in turn moves the limit screw sleeve vertically. This causes the movable plate to move downward and pulls the viscometer into the water-based coating inside the container to be measured. At the same time, the movable plate moves the contact seat to the top of the container via the support rod. When the top of the container is embedded in the contact groove, the contact seat is subjected to force, causing the support rod to retract into the housing and compress the spring. The spring applies pressure to the container through the support rod and the contact seat, achieving auxiliary fixation and preventing the container from tilting due to accidental contact during testing, which could cause the coating to splash. This ensures the stability of the container during the testing process.

[0014] 2. When the contact seat is subjected to force, the support rod retracts into the housing, which simultaneously drives the movable sleeve to move. The bottom ring retracts the bellows along with the movable sleeve, causing the viscometer to protrude from the bellows. After the movable plate moves up, the spring returns to its original position, causing the support rod to move down. The bellows is then expanded through the movable sleeve and the bottom ring, thus enclosing the viscometer to prevent dust and avoid long-term exposure to dust and impurities that could affect the detection accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] First implementation method:

[0022] refer to Figure 1-4 A water-based coating viscosity testing device includes a support frame 1, a movable plate 104 mounted on one side of the top of the support frame 1 via a lifting component, and a viscometer 105 for testing the viscosity of water-based coatings fixedly connected to the center of the bottom of the movable plate 104.

[0023] It also includes an anti-tipping mechanism 2, which includes two sets of housings 201 disposed on the top of the movable plate 104. A support rod 204 is installed inside the housing 201 via an elastic component, and the support rod 204 is located outside the viscometer 105. An abutment seat 205 for pressing the container storing water-based paint is installed at the bottom end of the support rod 204, and the support rod 204 penetrates the interior of the movable plate 104. An abutment groove 206 is opened inside the abutment seat 205, and the cross section of the abutment seat 205 is semi-circular.

[0024] The elastic component includes a spring 202 disposed inside the housing 201. The bottom end of the spring 202 is fixedly connected to the top end of the support rod 204, and a limiting bolt 203 extending out of the housing 201 is threadedly installed on one side of the bottom of the spring 202.

[0025] The lifting assembly includes a motor 101 disposed on one side of the top of the support frame 1. The output end of the motor 101 passes through one side of the top of the support frame 1 and is fixedly connected to a screw 102. A limiting screw sleeve 103 is threaded on the outside of the screw 102, and one end of the limiting screw sleeve 103 passes through one side of the support frame 1 and is fixedly connected to one side of the movable plate 104.

[0026] A protective box 4 is fixedly installed on one side of the support frame 1, and the protective box 4 is located outside the screw 102. Multiple sets of connecting shafts 5 are also provided on the outside of the support frame 1. A connector 501 is movably installed on the inner side of the connecting shaft 5. A threaded foot rod 502 is installed on the internal thread of one end of the connector 501.

[0027] First, pushing the connector 501 changes the position of the threaded rod 502. Then, rotating the threaded rod 502 adjusts the height of the device, thus adjusting the support range of the threaded rod 502. After placing the container containing water-based paint on top of the support frame 1, the motor 101 drives the screw 102 to rotate. The screw 102 drives the limiting screw sleeve 103 to move vertically. The limiting screw sleeve 103 drives the movable plate 104 to move downward. The movable plate 104 drives the viscometer 105 to probe into the container containing water-based paint for testing.

[0028] The viscometer 105 uses a TQ-810 vibratory viscometer. The viscometer 105 uses a built-in piezoelectric ceramic element to generate high-frequency vibrations with small amplitudes. The viscous resistance of the coating will cause the amplitude of the vibration to decrease or the frequency to change. By detecting this change in physical quantity and converting it into a viscosity value, the viscosity of water-based coatings can be detected.

[0029] The movable movable plate 104 drives the contact seat 205 to move via the support rod 204. The contact seat 205 moves to the top of the container to be measured containing water-based paint, so that the top of the container to be measured containing water-based paint enters the interior of the contact groove 206.

[0030] The contact seat 205 is subjected to force, which drives the support rod 204 to retract into the housing 201. This, in turn, causes the spring 202 to be elastically compressed. The spring 202, through the support rod 204 and the contact seat 205, presses and fixes the container containing the water-based paint to be measured. This achieves the purpose of auxiliary fixation of the container containing the water-based paint, avoiding the problem that the container is easily touched by the operator when testing the viscosity of the water-based paint inside the container, which may cause it to tilt and splash the water-based paint into the surrounding environment. This ensures the stability of the storage container when testing the viscosity of the water-based paint.

[0031] The travel of the spring 202 can be locked by rotating the limit bolt 203, thereby limiting the movement of the contact seat 205. The protective box 4 can prevent the operator from being injured by accidentally touching the screw 102.

[0032] Second implementation method:

[0033] The surface of a viscometer exposed to the environment for a long time is prone to adsorbing impurities and dust, which can lead to dust and impurities entering the interior of the water-based coating during viscosity testing, resulting in a decrease in testing accuracy.

[0034] refer to Figure 3-4 In the second embodiment of this utility model, a dustproof mechanism 3 is also included. The dustproof mechanism 3 includes a corrugated pipe 301 disposed at the bottom of the movable plate 104, and the corrugated pipe 301 is located between the viscometer 105 and the support rod 204. The bottom end of the corrugated pipe 301 is fixedly connected to a bottom ring 302, and two sets of movable sleeves 303 are fixedly connected to the outside of the bottom ring 302. The movable sleeves 303 are located on the outside of the lower end of the support rod 204, and a locking member 304 is threadedly installed on one side of the movable sleeves 303.

[0035] The contact seat 205 is subjected to force and drives the support rod 204 to retract into the housing 201. The moving support rod 204 drives the moving sleeve 303 to move synchronously. The moving sleeve 303 drives the bellows 301 to contract through the bottom ring 302, so that the viscometer 105 extends out of the bellows 301.

[0036] Conversely, when the movable plate 104 moves upward, the spring 202, after the resistance force disappears, drives the support rod 204 downward through the high elastic force of the spring 202. The support rod 204 drives the bottom ring 302 to move through the movable sleeve 303. The bottom ring 302 drives the bellows 301 to extend and unfold, thereby enclosing the outside of the viscometer 105, realizing the function of enclosing and preventing dust from the viscometer 105. This solves the problem that the surface of the viscometer 105, which is exposed to the environment for a long time, is prone to adsorbing impurities and dust, which causes dust and impurities to enter the interior of the water-based coating during viscosity testing. This ensures the accuracy of water-based coating viscosity testing. The bellows 301 can be locked in its extension and retraction state by rotating the locking part 304.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
