Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coating testing, in particular to a rotary test bench. Background Art
[0002] The sag resistance test is a test of the adhesion performance of a coating after being coated on a vertical surface. Currently, during operation, the coated substrate is first placed on a platform, then a sag ruler is placed on the substrate, and then a certain amount of coating is poured on the front side of the sag ruler. Then, the sag ruler is moved, and the coating is brushed on the substrate to form multiple brushing marks. Then, the substrate is placed vertically on a placement rack, and when placing, the length direction of the marks is horizontal. Then, the sag resistance of the marks is observed and rated. When testing in this way, the straightness of the brushing marks cannot be ensured, which affects the test results. Moreover, when placed vertically, its verticality cannot be ensured, so it also affects the test results. At the same time, for some coatings with poor sag resistance, during the test, the coating is likely to drip onto the placement rack, thus affecting the cleanliness of the test device. Summary of the Utility Model

[0018] As Figures 1 to 4As shown in the figure, a rotary test bench includes a bottom plate 1, and a pair of cushion plates 10 are provided on the upper wall of the bottom plate 1. One end of the bottom plate 1 is provided with a rectangular frame 2, and a movable block 20 is movably arranged in the rectangular frame 2. An L-shaped plate 21 is rotatably arranged on the movable block 20. The inner end of the L-shaped plate 21 is provided with a cross plate 22. One end of the cross plate 22 is provided with a placing cushion plate 200. A lead screw 33 is rotatably arranged on the cross plate 22. The outer end of the lead screw 33 is provided with an end cap 34. A pair of guide holes 24 are respectively opened at both ends of the cross plate 22. Connecting screws 25 are arranged in the guide holes 24. The outer ends of the connecting screws 25 at the same end are provided with movable outer plates 28. A pair of side plates 29 are arranged on the movable outer plates 28. Oblique holes 30 are opened on the side plates 29. There is an included angle between the length direction of the oblique holes 30 and the length direction of the side plates 29. A moving rod 31 is arranged in the oblique holes 30. A moving cross plate 32 is screwed on the lead screw 33. The moving rod 31 is rotatably arranged at the end of the moving cross plate 32. The inner ends of the connecting screws 25 at the same end are provided with limiting concave parts 26. The cushion plate 10 is located below the limiting concave parts 26.
[0019] A vertical plate 27 is arranged on the upper side of the limiting concave part 26. A long hole 35 is opened on one of the vertical plates 27. A concave sleeve 36 is sleeved on the vertical plate 27. A moving handle 37 is arranged on the concave sleeve 36. A connecting middle rod is arranged on the concave sleeve 36. The connecting middle rod passes through the long hole 35. The inner end of the connecting middle rod is provided with a concave inner part 38. A clamping block 39 is arranged inside the concave inner part 38. A clamping lead screw 40 is screwed at one end of the concave inner part 38. The outer end of the clamping lead screw 40 is provided with a rotating cap 42. The inner end of the clamping lead screw 40 is rotatably provided with an inner clamping plate 41. A sag ruler is clamped between the inner clamping plate 41 and the clamping block 39.
[0020] During the operation of this embodiment, the operator first passes the base material through between the limiting concave parts 26.
[0021] Then, the operator rotates the lead screw 33 through the end cap 34. The rotation of the lead screw 33 will drive the cross plate 22 to move. When the cross plate 22 moves, it will act on the oblique holes 30 through the moving rod 31 thereon, thereby making the movable outer plates 28 approach each other. When the movable outer plates 28 approach each other, they will clamp and limit the base material through the limiting concave parts 26.
[0022] Then, a suitable sag ruler is selected, and one end of the sag ruler is installed between the clamping block 39 and the inner clamping plate 41, and the sag ruler is fixed by rotating the clamping lead screw 40.
[0023] Then, the operator pours the paint on the front side of the sag ruler, and then moves the sag ruler through the moving handle 37. When moving, the paint is applied to the base material through the sag ruler.
[0024] Then, the operator first moves the substrate upward. When it rises to a certain height, the operator rotates the substrate, makes the length direction of the brushing mark horizontal, and makes the vertical plate 27 located on the lower side. At the same time, after the rotation is completed, the placement pad 200 needs to be placed on the bottom plate 1.
[0025] Finally, the operator observes the mark.
[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
