Description

Technical Field

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

[0002] As an environmentally friendly building and industrial material, the application performance of water-based coatings is greatly affected by viscosity parameters. Therefore, viscosity measurement is an indispensable part of coating quality control and formulation adjustment. Common methods for measuring the viscosity of water-based coatings include the rotational viscometer method and the flow-through cup method. The flow-through cup method is widely used in laboratories and production sites due to its simplicity and lower cost.

[0003] However, in practical applications, existing viscosity cup measurement devices still suffer from numerous structural problems, affecting the accuracy and ease of operation of viscosity measurements. Firstly, existing viscosity cups are mostly manually suspended on fixed supports. If the support structure cannot be precisely leveled, the viscosity cup can easily tilt, causing the outlet direction to deviate from the vertical line of gravity, thus affecting the accuracy of outflow time measurement. Secondly, different types of viscosity cups (such as DIN cups, FORD cups, etc.) differ in size and structure. If the device lacks an adjustable, universal support structure, it is often difficult to accommodate multiple cup sizes, limiting the device's applicability. Furthermore, existing devices lack structural designs for stable positioning and anti-shaking of the viscosity cup, which can easily cause slight oscillations during use, affecting the stability of the liquid flow.

[0004] In summary, existing water-based coating viscosity measurement devices have shortcomings in terms of support structure adjustment, vertical positioning of the viscosity cup, and adaptability. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an improved viscosity measuring device for water-based coatings. This improved viscosity measuring device can achieve stable structure, strong adaptability, and ensure measurement accuracy, thereby improving the reliability and practicality of the measurement process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A water-based coating viscosity measuring device includes a base, and a support arm is provided above one end of the base. The support arm includes a fixed column and a movable column, and the movable column and the fixed column are movably connected.

[0008] The top of the movable column is connected to a crossbar, and a suspension mechanism is provided at one end of the crossbar;

[0009] A viscosity cup is placed on the suspension mechanism; the viscosity cup is used to store the coating to be tested.

[0010] The upper surface of the base is provided with a collection bucket, which is used to collect the paint flowing out of the viscosity cup.

[0011] Furthermore, the viscosity cup is configured as a funnel shape, and a plug is inserted into the bottom outlet end of the viscosity cup, while a positioning ring is provided on the outer side of the top opening end of the viscosity cup.

[0012] Furthermore, the suspension mechanism includes a plug-in post inserted into the crossbar, with hooks symmetrically arranged at the bottom of the plug-in post. The number of hooks is set to two, and a pin is placed on each hook. A positioning plate is fixedly connected to the pin, and the positioning plate is located between the two hooks.

[0013] An ear bracket is rotatably connected to the pin;

[0014] The top two sides of the ear bracket are provided with pin joint plates, and the two ends of the pin are inserted into the pin joint plates;

[0015] The bottom of the ear frame is rotatably connected to a retaining ring, and a pin connector is provided on the retaining ring. The pin connector and the ear frame are rotatably connected by a plug-in method.

[0016] The viscosity cup is inserted into the retaining ring, and the positioning ring abuts against the upper end face of the retaining ring.

[0017] Furthermore, one end of the crossbar has a through-hole, a plug is inserted into the plug hole, and a gripping ball is fixedly connected to the top of the plug.

[0018] Furthermore, a cap is fixedly connected to the other end of the crossbar, and a locking hole is provided through the bottom of the cap;

[0019] A threaded post is fixedly connected to the top of the movable post, and the threaded post passes through the locking hole.

[0020] Furthermore, the top of the fixed column is provided with a plug-in groove, into which the movable column is inserted;

[0021] The insertion slot has a positioning groove inside, and the outer side of the movable column is fixedly connected with a positioning strip corresponding to the positioning groove.

[0022] A locking seat is provided on the outer side of the upper end of the fixing column, and a locking knob is connected to the locking seat.

[0023] Furthermore, a mounting base is provided on one end of the base, and a connecting thread is provided on the outer side of the bottom of the fixing column.

[0024] Furthermore, the upper surface of the base is provided with an anti-slip pad, and the bottom of the base is symmetrically provided with support feet, which are threadedly connected to the base.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] The device features a support base with anti-slip pads, allowing for horizontal adjustment of the viscosity measuring device during use. This enhances the stability of contact with the worktable and solves the problems of existing devices being unable to level quickly and having large measurement errors. As a result, the viscosity cup remains vertical during measurement, improving the accuracy and repeatability of viscosity readings.

[0027] The device features a support arm structure consisting of a fixed column and a movable column, with an adjustable locking structure between the movable column and the crossbar. This allows for flexible adjustment of the viscosity cup's suspension height to accommodate different collection containers. Furthermore, the combination of a positioning groove and a positioning strip ensures stable positioning of the column, solving the technical problems of poor adaptability and non-adjustable viscosity cup installation height in existing devices. This enhances the device's applicability and ease of operation.

[0028] The device has a plug-in hole at one end of the crossbar and a detachable plug-in post. A pin is connected to the bottom of the plug-in post via a hook. A rotating lug and a retaining ring structure are set on the pin. The viscosity cup is vertically limited by the positioning ring and the retaining ring, and the angle can be corrected by rotating the lug. This ensures that the viscosity cup can further achieve self-adjustment verticality on the basis of the device leveling. This solves the problems of viscosity cup tilting and unstable liquid flow path in the existing structure and ensures the stability of the liquid during the natural flow process under gravity.

[0029] The device has a collection bucket below the viscosity cup, which can directly receive the outflowing liquid, avoiding interruptions or splashing caused by errors in the placement of external liquid receiving containers during the measurement process, thus further improving operational safety and measurement consistency.

[0051] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0052] See Figure 1-7A water-based coating viscosity measuring device includes a base 1, which is a rectangular flat plate structure made of corrosion-resistant aluminum alloy. A support arm 3 is mounted on one end of the base 1. The support arm 3 includes a fixed column 31 and a movable column 32. The fixed column 31 is installed in a mounting base 13 at one end of the base 1 via a connecting thread 311 to form a stable column structure. The movable column 32 is inserted into the top insertion groove 312 of the fixed column 31 and cooperates with a positioning groove 3121, with positioning and guidance provided by a positioning strip 321. The support arm 3 provides a vertical support channel for the upper viscosity cup 6, preventing the measurement... Structural shift occurs during the process; a crossbar 4 is connected to the top of the movable column 32. The crossbar 4 is a hollow steel pipe structure. The crossbar 4 is connected to the movable column 32 through a threaded column 322 and a locking hole 42. A suspension mechanism 5 is provided at one end of the crossbar 4. The suspension mechanism 5 is used to suspend and stably support the viscosity cup 6. The viscosity cup 6 is used to store the coating to be tested and complete the measurement by gravity natural flow-out. A collection bucket 2 is provided on the upper end face of the base 1. The collection bucket 2 is a hollow stainless steel container. The opening of the collection bucket 2 faces upward and is used to receive the water-based coating flowing out of the viscosity cup 6 and maintain the stability of the flow path.

[0053] See Figure 7 The viscosity cup 6 is funnel-shaped and made of transparent polycarbonate material to facilitate observation of the flow state. The inside of the viscosity cup 6 is smooth to ensure uniform flow of the coating. A plug 62 is inserted into the bottom outlet end of the viscosity cup 6. The plug 62 is a conical rubber stopper that fits tightly with the bottom of the cup to control the start time of measurement. A positioning ring 61 is provided on the outer side of the top opening end of the viscosity cup 6. The positioning ring 61 is an integrally formed boss structure. The positioning ring 61 is used to engage with the retaining ring 54 to ensure that the axial position of the viscosity cup 6 remains constant during the suspension process, effectively preventing the viscosity cup 6 from being affected by shaking during the measurement process.

[0054] See Figure 6-7The suspension mechanism 5 includes a plug-in post 51 inserted into the crossbar 4. The plug-in post 51 is a short post structure. Hooks 512 are symmetrically arranged at the bottom of the plug-in post 51. The number of hooks 512 is set to two and located on both sides of the plug-in post 51. The hooks 512 are made of bent steel sheets and are fixedly connected to the plug-in post 51 by threads. A pin 52 is placed on the hook 512. The pin 52 is a horizontally arranged metal rod. A positioning plate 521 is fixedly connected to the pin 52. The positioning plate 521 is located between the two hooks 512 and is used to maintain the axial position of the pin 52. An ear bracket 53 is rotatably connected to the pin 52. The ear bracket 53 is a U-shaped metal frame structure used to form a connection with the viscosity cup 6. The rotating bracket; pin plates 531 are provided on both sides of the top of the ear bracket 53. The pin plates 531 are L-shaped reinforcing plates. The two ends of the pins 52 are inserted into the pin plates 531 to realize the free swing of the ear bracket 53; a retaining ring 54 is rotatably connected to the bottom of the ear bracket 53. The retaining ring 54 is an annular support frame. A pin joint 541 is provided on the retaining ring 54. The pin joint 541 and the ear bracket 53 are rotatably connected by a plug-in method, which allows the retaining ring 54 to be slightly adjusted in the vertical direction relative to the ear bracket 53; the viscosity cup 6 is inserted into the retaining ring 54, and the positioning ring 61 abuts against the upper end face of the retaining ring 54, so that the outlet end of the viscosity cup 6 is always vertically downward under the action of gravity, ensuring the stability of the outflow path.

[0055] See Figure 6-7 One end of the crossbar 4 has a through-hole 43, which is a round hole structure that matches the plug post 51 and is used to plug in the suspension assembly. After the plug post 51 is inserted into the plug hole 43, it is fixed by friction to form a stable connection structure. The top of the plug post 51 is fixedly connected to a grip ball 511, which is a non-slip ball head structure. The grip ball 511 makes it easy for the operator to manually adjust when installing or disassembling the suspension mechanism 5, thus improving the ease of operation of the device.

[0056] See Figure 4-5 The other end of the crossbar 4 is fixedly connected to a cap 41, which is an embedded tube cap structure. A locking hole 42 is provided through the bottom of the cap 41. The locking hole 42 is used to engage with the threaded post 322 provided on the top of the movable post 32 for threaded locking. The top of the movable post 32 is fixedly connected to the threaded post 322. After the threaded post 322 passes through the locking hole 42, it can be fastened to form a detachable connection between the crossbar 4 and the movable post 32, which facilitates the horizontal adjustment and component replacement of the measuring device at different heights.

[0057] See Figure 4The top of the fixed column 31 is provided with an insertion groove 312, which is a rectangular guide groove. The movable column 32 is inserted into the insertion groove 312 and initially limited under the guidance of the insertion groove 312. The inside of the insertion groove 312 is provided with a positioning groove 3121, which is a groove structure for the cooperation of the guide strip. The outer side of the movable column 32 is fixedly connected with a positioning strip 321 corresponding to the positioning groove 3121. The positioning strip 321 cooperates with the positioning groove 3121 to prevent the movable column 32 from rotating and shifting, and to maintain the verticality of the support structure. The upper outer side of the fixed column 31 is provided with a locking seat 313, which is an annular seat with a threaded hole. A locking knob 33 is connected to the locking seat 313. The locking knob 33 pushes the locking part to press the movable column 32 by rotation, thereby achieving height locking and ensuring that the viscosity cup 6 maintains a stable suspension height during measurement.

[0058] See Figure 2-4 A mounting base 13 is provided on the upper part of one end of the base 1. The mounting base 13 is an integrally formed protruding structure. The interior of the mounting base 13 is provided with a threaded hole for mounting the fixed column 31. The bottom outer side of the fixed column 31 is provided with a connecting thread 311. The connecting thread 311 is installed in conjunction with the threaded hole of the mounting base 13 to form a stable support structure for supporting the upper support arm 3 and the crossbar 4.

[0059] See Figure 1-3 The upper surface of the base 1 is provided with an anti-slip pad 11, which is made of rubber composite material. The anti-slip pad 11 is used to enhance the friction between the base 1 and the contact platform and prevent the device from sliding during the measurement process. The bottom of the base 1 is symmetrically provided with support feet 12, which are threadedly connected to the base 1. The height of the support feet 12 can be adjusted by rotation, thereby realizing the horizontal adjustment of the entire measuring device and ensuring that the liquid outlet direction of the viscosity cup 6 is always perpendicular to the ground, thus improving the accuracy and repeatability of the measurement.

[0060] The working principle of this utility model is as follows:

[0061] In use, the operator first screws the connecting thread 311 of the fixed column 31 into the mounting seat 13 on the base 1 to form a stable support, and then adjusts the base 1 horizontally using the support feet 12 to ensure that the device is stable and level with the ground. Next, the movable column 32 is inserted into the insertion slot 312 of the fixed column 31, aligning its outer positioning strip 321 with the positioning groove 3121 within the insertion slot 312 to prevent the column from rotating or shifting. The movable column 32 can be locked at the desired height using the locking knob 33 on the locking seat 313, allowing for coarse adjustment of the height of the crossbar 4.

[0062] A cap 41 at one end of the crossbar 4 is fitted onto the threaded post 322 at the top of the movable post 32, and the crossbar 4 is fixed in place by the locking hole 42, keeping it horizontally extended. The other end of the crossbar 4 has an insertion hole 43 into which the insertion post 51 is inserted. The grip ball 511 at the top of the insertion post 51 facilitates rotation or adjustment of the insertion direction by the operator. A pin 52 is fixed between two hooks 512 at the bottom of the insertion post 51. A positioning plate 521 and an ear bracket 53 are mounted on the pin 52, forming a rotating connection structure that supports the viscosity cup.

[0063] The top of the ear bracket 53 is connected to both ends of the pin 52 via a pin plate 531, and the bottom is rotatably connected to the retaining ring 54 via a pin connector 541, forming a swingable viscosity cup suspension structure. The operator inserts the viscosity cup 6 into the retaining ring 54, with the positioning ring 61 abutting against the upper surface of the retaining ring 54, thus fixing the cup in place. The rotatable connection between the ear bracket 53 and the retaining ring 54 ensures that the viscosity cup 6 remains vertical after the device is leveled, with its bottom outlet naturally facing downwards, ensuring a stable flow of liquid under gravity.

[0064] Before measurement, remove the plug 62 inserted at the bottom of the viscosity cup 6, allowing the paint to flow naturally from the bottom of the cup into the collection bucket 2 below. The outflow time is measured by determining the time required for the liquid to stop flowing, thus assessing the viscosity of the paint. Throughout the measurement process, the anti-slip pad 11 enhances the stable contact between the cup and the base, improving measurement accuracy.

[0065] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
