Description

Technical Field

[0001] The utility model relates to the technical field of building paint performance detection, in particular to a building paint performance detection device. Background Art

[0002] Architectural coatings are materials that can be applied to the surface of objects and can bond well with the base material to form a complete and tough protective film. During the construction of a building project, the performance of the coating directly affects the quality of the building. Coatings used outdoors will be exposed to the sun for a long time and in a high temperature environment. Under high temperature conditions, the coating is prone to cracking or even falling off, exposing the protected walls, causing water seepage and leakage after rainy weather, which in turn affects the overall quality of the construction project. Therefore, it is necessary to use performance testing equipment to test the heat resistance and anti-falling performance of the coating.

[0003] Existing testing devices for the performance of architectural coatings are generally composed of a placement plate, a support mechanism and a heating tube. When testing the heat resistance of a coated plate, the coated plate is first placed on the placement plate, and then the surface of the coated plate is baked by the heating tube, so that the coated plate can be heated for the heat resistance test.

[0004] In the existing detection device for the performance of architectural coatings, when testing the heat resistance of the coating, it is difficult to adjust the distance between the heating structure and the coating plate according to the actual testing requirements because the heating structure is fixed, thereby making it difficult to adjust the testing temperature of the coating plate. In addition, since the range of coating on the coating plate is large, the coating plate cannot be heated evenly during the heating process, which will affect the effect of coating testing. Therefore, a device for detecting the performance of architectural coatings is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes a building coating performance detection device.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: the utility model describes a building coating performance detection device, comprising a base; a threaded rod is rotatably installed on one side of the top of the base, a driven gear is sleeved on the bottom end of the threaded rod, a driving gear is rotatably installed on the base through a rotating shaft, and the driving gear and the driven gear are meshed with each other, a turntable is fixedly connected to the top of the rotating shaft, a guide rod is fixedly connected to the other side of the top of the base, the guide rod and the top of the threaded rod are both equipped with limiting caps, the guide rod and the threaded rod are both sleeved with lifting blocks, and the lifting blocks are slidably connected to the guide rod and screwed to the threaded rod.

A limiting slot is provided on the horizontal plate, and a motor is installed on one side of the end of the limiting slot, and a fixed plate is fixedly connected to the other side of the end of the limiting slot. When the distance between the heating structure and the coating plate is adjusted according to actual detection needs, the driving gear drives the driven gear to engage and rotate by rotating the turntable, and then the screw rod rotates. With the cooperation of the guide rod, the lifting block moves vertically, and then the horizontal plate drives the heating tube to move vertically, so that the distance between the heating tube and the coating plate can be adjusted, and the heating temperature of the coating plate can be adjusted, so as to facilitate the control of the temperature of coating detection.

After the coating plate is clamped and fixed, when the heat resistance of the coating is tested, the motor, in cooperation with the limiting groove, drives the mounting frame and the heating tube to move laterally. Under the action of the laterally moving heating tube, the surface of the coating plate can be evenly baked, so that the heat is more evenly distributed on the coating plate, which facilitates the uniform heating of the coating applied on the coating plate, thereby improving the effect of the coating heat resistance test.

In order to avoid the position of the coated plate from shifting during the detection process, when clamping and positioning the coated plate, the coated plate with paint is first placed on the base. Then, the pneumatic cylinder is used to drive the connecting plate to move along the groove. With the cooperation of the slide groove and the guide groove, the moving block drives the two clamping plates to move closer to each other until the two clamping plates are in contact with both sides of the coated plate. In this way, the coated plate can be clamped and positioned to prevent the coated plate from being displaced during the heat detection process and affecting the subsequent test results, which is convenient for the subsequent accurate heat resistance performance testing of the coated plate.
