[0002] For substrate and coating or coating and coating, the adhesion of coating is usually detected. The common pull-off method adhesion test is that a spindle is bonded on the substrate to be tested covered with a coating, such as an iron plate, and is cured for a period of time; before detection, a cutter is used to cut the coating around the spindle in a ring shape to form a fixed area of coating around the spindle, thereby ensuring the detection effect.

DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0028] Please refer to Figure 1 The coating ring cutting device based on the anticorrosive coating adhesion detection provided by the utility model will be described. The coating ring cutting device based on the anticorrosive coating adhesion detection comprises a body 10, a rotating drum 20, a driving structure 30 and a positioning structure 40. The body 10 has a rotatable adapter. One end of the rotating drum 20 is coaxially connected with the adapter, and the other end has an open cavity. An annular sawtooth part 21 is arranged at the window of the open cavity. The driving structure 30 is arranged on the body 10 and can drive the adapter to rotate. The positioning structure 40 is arranged on the body 10 and has a contact part extending into the open cavity. The contact part is provided with a positioning groove 45 adapted to the hanging end of the spindle 50.

[0029] The coating ring cutting device based on the anticorrosive coating adhesion detection provided by the embodiment uses the principle that after the spindle 50 is bonded and solidified with the coating, the staff member holds the body 10, the open cavity of the rotating drum 20 is arranged downward and covers the spindle 50, at this time, the hanging end at the top of the spindle 50 extends into the positioning groove 45 for positioning, at this time, the driving structure 30 is started to drive the adapter to rotate, thereby driving the rotating drum 20 to rotate, and annular cutting is formed by the annular sawtooth part 21 in contact with the coating.

[0030] Compared with the prior art, the driving structure 30 arranged on the body 10 is connected with the adapter and can drive the adapter to rotate, thereby realizing the rotation of the rotating drum 20, ensuring the annular cutting of the annular sawtooth part 21 on the coating, reducing the labor, and being suitable for relatively thick coatings. The contact part arranged in the rotating drum 20 can ensure the positioning of the rotating drum 20 during the covering of the rotating drum 20 outside the spindle 50, ensure the coaxial arrangement of the rotating drum 20 and the spindle 50, thereby ensuring the concentricity of the annular cutting seam and the spindle 50, ensuring the final detection effect, and having high practicability.

[0031] In some embodiments, the machine body 10 can adopt the structure as shown in Figure 1 . Referring to Figure 1 , the machine body 10 comprises a base 11 and a rotating sleeve 12. The base 11 has a fixed cylinder extending outward. The rotating sleeve 12 is sleeved on the fixed cylinder and is rotationally connected with the fixed cylinder, and the rotating sleeve 12 is a rotating adapter.

[0032] The fixed cylinder provided on the base 11 can ensure the rotational connection of the rotating sleeve 12, thereby ensuring that the rotating sleeve 12 drives the rotating drum 20 to rotate.

[0033] In this embodiment, a one-way bearing 14 can be provided between the rotating sleeve 12 and the fixed cylinder, and the rotating sleeve 12 can only rotate in one direction under the driving of the driving structure 30.

[0034] In some embodiments, the base 11 can adopt the structure as shown in Figure 1 . Referring to Figure 1 , the base 11 is provided with a hand-held handle 13 at an end away from the rotating sleeve 12. The hand-held handle 13 can be conveniently held by the staff, thereby facilitating the application of pressure to the coating in a normal direction to release the pressure of the coating and ensuring the cutting effect of the coating.

[0035] It should be noted that a press switch can be provided on the hand-held handle 13. After the preparation work is completed, the staff can directly start the driving structure 30 through the press switch, thereby realizing the annular cutting.

[0036] In some embodiments, the rotating drum 20 can adopt the structure as shown in Figure 1 . Referring to Figure 1 , the rotating drum 20 is detachably connected with the rotating adapter. This structure can replace rotating drums 20 of different specifications according to different spindles 50, thereby improving the adaptability.

[0037] In this embodiment, the rotating drum 20 can be connected with the rotating adapter through threads. Specifically, the rotating sleeve 12 rotates in one direction, and the thread direction of the threaded connection can be opposite to the rotating direction of the rotating sleeve 12, thereby facilitating the detachable connection of the rotating drum 20 and also ensuring that the rotating drum 20 does not fall off during the rotation of the rotating sleeve 12. When the rotating drum 20 is detached, the driving structure 30 or the rotating sleeve 12 can be manually pressed to fix the rotating sleeve 12, so that the rotating sleeve 12 does not rotate, thereby realizing the detachment of the rotating drum 20.

[0038] In some embodiments, the driving structure 30 can adopt the structure as shown in Figure 1 . Referring to Figure 1The drive structure 30 includes a driven gear 31 and a driver 32. The driven gear 31 is fixedly sleeved on the adapter. The driver 32 is fixed on the body 10, and its power output end is connected to a driving gear 33, which meshes with the driven gear 31. The driven gear 31 is coaxially fixedly connected to the adapter. After the driver 32 drives the driving gear 33 to rotate, it in turn drives the driven gear 31 to rotate, thereby driving the adapter. Its structure is simple, the drive is convenient, and it can reduce manpower.

[0039] It should be noted that the diameter of the driving gear 33 is smaller than the diameter of the driven gear 31, thereby ensuring the deceleration effect and increasing the torque.

[0040] In some embodiments, the positioning structure 40 described above can be as follows: Figure 1 The structure shown. See also Figure 1 The positioning structure 40 includes a sliding column 41, a positioning cap 42, a limiting plate 43, and a spring 44. The sliding column 41 is coaxially arranged with the adapter and slidably connected to the body 10 along the axis of the adapter. One end of the sliding column 41 extends into the opening cavity, and the other end extends into the limiting cavity in the body 10. The positioning cap 42 is located in the opening cavity and connected to one end of the sliding column 41. The end of the positioning cap 42 facing outwards from the opening cavity has a positioning groove 45. The limiting plate 43 is located in the limiting cavity and connected to the other end of the sliding column 41. The spring 44 is disposed in the limiting cavity, with one end abutting against the limiting plate 43 and the other end abutting against the inner wall of the limiting cavity.

[0041] Since different spindles 50 have different heights, the sliding connection between the sliding column 41 and the machine body 10 can ensure that the positioning cap 42 slides in the open mouth, thereby adapting to different spindle 50 specifications. At the same time, it can also ensure that the rotating drum 20 continuously contacts the spindle 50 and forms a positioning effect during the process of pressing down to cut the coating, thus ensuring the effect of ring cutting.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
