[0002] Paint refers to a type of liquid or solid material that can form a thin film under certain conditions when applied to the surface of an object to provide protection, decoration or other special functions. During the production process, it is usually necessary to test its viscosity to ensure that it meets production requirements. Existing paint viscosity tests usually need to be tested at room temperature. If the environment is too cold, the viscosity test may be inaccurate. Therefore, the paint needs to be heated to ensure that it can be tested at room temperature.

[0003] Existing paint viscosity testing devices usually have a heating wire built into the cup holder of the testing device. The heating wire is used to heat the viscosity cup, and the paint in the viscosity cup is heated to room temperature for testing. However, due to the different viscosities of different paints, the specifications of the selected viscosity cups are also different, and the diameters of viscosity cups of different specifications may also deviate. Therefore, there will be a gap of a certain size between the heating wire and the viscosity cup, and heat is easily leaked from the gap, so the heating efficiency is not high. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-2As shown, the utility model provides a coating viscosity detection device, which can improve the heating efficiency of the viscosity cup. The detection device is the same as the prior art in that it includes a base 1 and a cup holder bracket 2 arranged on the base 1, and the cup holder bracket 2 is provided with a heating component for supporting and heating the viscosity cup. The heating component includes a heating sleeve 3, and the inner wall of the heating sleeve 3 is provided with an annular groove 8, and the annular groove 8 is provided with a heating wire 7. By inserting the viscosity cup into the heating sleeve 3, the heating wire 7 heats the viscosity cup, so that the temperature of the coating in the viscosity cup can rise to room temperature, so as to carry out the detection procedure.

[0021] In this embodiment, the cup holder bracket 2 includes a vertical portion 202 disposed above the base 1 and a horizontal portion 201 penetrating the vertical portion 202 , and the outer side of the heating sleeve 3 is fixedly welded to the horizontal portion 201 .

[0022] The utility model is different from the prior art in that the heating assembly further comprises a plurality of heat-conducting sleeves 4 which can be plugged in with the heating sleeve 3. The outer diameters of the plurality of heat-conducting sleeves 4 are consistent with the inner diameter of the heating sleeve 3, and the inner diameters of the plurality of heat-conducting sleeves 4 are all different. The heat-conducting sleeves 4 with different inner diameters are used for plugging in viscosity cups of different specifications. When testing, a suitable heat-conducting sleeve 4 is selected according to the specifications of the viscosity cup. The heat-conducting sleeve 4 is first inserted into the heating sleeve 3, and then the viscosity cup is inserted into the heat-conducting sleeve 4. The heat generated by the heating wire 7 is transferred to the viscosity cup through the heat-conducting sleeve 4. The heat-conducting sleeve 4 can fill the gap between the heating wire 7 and the viscosity cup to prevent heat from leaking out of the gap, thereby improving the heating effect of the viscosity cup.

[0023] In order to allow the heat-conducting sleeve 4 to be inserted into the heat-conducting sleeve 4, a plurality of protrusions 5 are arranged in an array on the circumference of all heat-conducting sleeves 4, and slots 9 corresponding to the protrusions 5 are provided on the upper end surface of the heating sleeve 3, and the slots 9 are connected to the annular groove 8, so that most of the protrusions 5 enter the annular groove 8 and are close to the heating wire 7. At the same time, in order to improve the thermal conductivity of the heat-conducting sleeve 4 and the protrusions 5, their materials are set to copper or aluminum, and the protrusions 5 account for 20-40% of the outer circumferential area of ​​the heat-conducting sleeve 4, preferably 30%.

[0024] The position of the heat-conducting sleeve 4 is limited by the insertion and cooperation between the protrusion 5 and the slot 9. Meanwhile, the arrangement of the protrusion 5 can increase the heated area of ​​the heat-conducting sleeve 4, further improving the heat conduction efficiency.

[0025] In this embodiment, an annular hollow cavity 6 surrounding the annular groove 8 is provided on the cylinder body of the heating sleeve 3. The heat preservation performance of the heating sleeve 3 is improved by the annular hollow cavity 6. At the same time, the upper part of the annular hollow cavity 6 can be extended to the upper part of the heating sleeve 3, so that the annular hollow cavity 6 can be filled with heat insulation cotton to prevent a large amount of heat energy loss.

[0026] In this embodiment, a temperature sensor is provided in the annular groove 8, and the temperature in the annular groove 8 is monitored by the temperature sensor, so that the staff can monitor the temperature.

[0027] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention.
