[0022] In order to better understand the purpose, structure and function of the utility model, the specific embodiment of the utility model "a trimming knife detection device" is further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1-Figure 3In this embodiment, the detection device includes a detection mechanism 100 and a rotation positioning mechanism 200. The rotation positioning mechanism 200 includes a base 201. A foot 206 is provided at the bottom of the base 201 to increase the stability of the base 201 and the firmness of the installation; an axle pin 202 is rotatably provided on the base 201, and a circular ring disk 203 is coaxially fixedly sleeved on the axle pin 202, and a trimming knife 204 is coaxially sleeved on the circular ring disk 203; a limiting member 205 is also provided on the axle pin 202, and the limiting member 205 can move along the axle pin 202 and abut the trimming knife 204 to fix the trimming knife 204 on the circular ring disk 203; the detection mechanism 100 abuts the trimming knife 204, and the axle pin 202 drives the trimming knife 204 to rotate for detection. This device can conveniently position the annular trimming knife 204 and drive the trimming knife 204 to rotate through the cooperation of the rotatable shaft pin 202, the annular sleeve 203 and the limit member 205. While the trimming knife 204 rotates, the detection mechanism 100 can accurately detect whether the trimming knife 204 has defects and what defects exist.

[0024] See also Figure 1 and Figure 2 In this embodiment, the detection mechanism 100 includes a fixed bracket 101, which is a multi-joint movable bracket, and a detection gauge 102 is detachably fixed at one end thereof. By changing the position and direction of the movable joint of the fixed bracket 101, the position where the detection gauge 102 abuts against the trimming knife 204 can be conveniently adjusted so as to perform a more comprehensive detection of the trimming knife 204. It should be noted that in this embodiment, the detection gauge 102 is preferably a dial indicator or a micrometer to improve the accuracy of the defect detection of the trimming knife 204. Of course, in other embodiments, the detection gauge 102 can also be other detection equipment as long as it can meet the purpose of detecting the defects of the trimming knife 204.

[0025] See also Figure 1 In this embodiment, the detection mechanism 100 and the rotation positioning mechanism 200 are independently arranged. The two are arranged at corresponding positions to cooperate in the detection operation to form a complete detection device, which is convenient for installation and will not interfere with each other. Of course, in some implementations, the detection mechanism 100 and the rotation positioning mechanism 200 can be integrated into one, and the fixed bracket 101 is arranged on the base 201 to form a detection device as a whole based on the base 201, which is convenient for the transportation of the entire device.

[0026] See also Figure 3 In this embodiment, a rotating hole 207 is provided on the base 201, a bearing 208 is provided in the rotating hole 207, the shaft pin 202 is passed through the bearing 208, and is fixedly connected to the inner ring of the bearing 208 so that the shaft pin 202 can rotate relative to the base 201.

[0027] More specifically, in this embodiment, a thread 209 is provided on the shaft pin 202, the limit member 205 is a disc-shaped workpiece and is coaxially sleeved on the shaft pin 202, and the limit member 205 is threadedly connected to the shaft pin 202 so as to tighten the limit member 205 to abut and position the trimming knife 204, or loosen the limit member 205 so as to replace and install the trimming knife 204.

[0028] Furthermore, in this embodiment, in order to facilitate the operator to rotate the shaft pin 202 and the stopper 205, anti-slip grooves 211 are provided on the shaft pin 202 and the stopper 205. At the same time, in order to enable the stopper 205 to abut against the trimming knife 204 without interfering with the detection of the detection mechanism 100, a circular protrusion 201 is provided on the stopper 205, and the circular protrusion 201 abuts against the inner ring of the trimming knife 204 to limit the trimming knife 204. The use of the coaxially connected circular stopper 205 and the circular protrusion 201 can better position the trimming knife 204, and during the rotation detection process of the trimming knife 204, the detection accuracy will not be reduced due to the center of gravity offset of the rotation positioning mechanism, thereby improving the accuracy of the defect detection of the trimming knife.
