When the clamping manipulator 31 is at the unloading position, the dental floss stick feeding device 4 can transfer the dental floss on the dental floss rack to the dental floss box. However, since the existing dental floss rack usually includes a plurality of material rods for receiving dental floss, each material rod is arranged like a comb, and each material rod is To receive multiple dental flosses, when all the dental flosses on the first material rod on the dental floss material rack have been transferred into the dental floss box, the feeding motor 32 can drive the clamping robot 31 located at the unloading position to move a certain distance (the distance is the spacing between the two material rods), so that the second material rod can correspond to the dental floss stick feeding device 4, which is convenient for moving the dental floss thereon for boxing. The feeding motor 32 drives the clamping robot 31 to repeatedly move intermittently until all the dental flosses on the dental floss material rack have been transferred into the dental floss box, thereby making automatic feeding of the dental floss stick possible.

When in use, the first clamping manipulator 31 is located at the loading position, at which time the material rack loading device 2 can convey the dental floss material rack to correspond to the first clamping manipulator 31, so that it is convenient for it to clamp the dental floss material rack, and then the feeding motor 32 drives the first clamping manipulator 31 to leave and allows the second clamping manipulator 31 to be located at the loading position, and then the material rack loading device 2 conveys another dental floss material rack to correspond to the second clamping manipulator 31, so that it is convenient for it to clamp the dental floss material rack, and finally the feeding motor 32 drives the two clamping manipulators 31 to move to the lower material position.

[0029] A positioning sensor 33 capable of detecting the moving position of the clamping manipulator 31 is provided between the main frame 1 and the clamping manipulator 31, and the positioning sensor 33 is in communication connection with the feeding motor 32. The positioning sensor 33 is a well-known technology and adopts a common design. The positioning sensor 33 includes a sensor probe provided on the main frame 1 and a probe detection member provided on the clamping manipulator 31. When the sensor probe detects the probe detection member during the movement of the clamping manipulator 31, the feeding motor 32 can be stopped, thereby facilitating the improvement of the positioning accuracy of the clamping manipulator 31.

[0031] The transfer component 41 may also include a limiting rod 415 that can prevent the dental floss stick on the transfer rod 4111 from falling off. The limiting rod 415 is bent into a C-shaped structure, and one end of the limiting rod 415 is corresponding to the transfer rod 4111 in the transfer loading state, and the other end is corresponding to the transfer rod 4111 in the transfer unloading state. The shape of the limiting rod 415 is similar to the rotation trajectory of the outer end of the transfer rod 4111, which can effectively prevent the dental floss stick on the transfer rod 4111 from being thrown off during the rotation of the transfer frame 411.

[0032] The transfer component 41 also includes a transfer support 416 for adjusting the inclination angle of the dental floss stick. The transfer support 416 is located below the transfer rod 4111 in the transfer unloading state. The gap between the transfer support 416 and the transfer rod 4111 determines the inclination angle of the dental floss stick at this location. By adjusting the gap between the transfer support 416 and the transfer rod 4111, the inclination angle of the dental floss stick at this location is adapted to the rotation limiting structure on the feeding rod 421, which is beneficial to improve the stability of the dental floss stick during the process of transferring from the transfer rod 4111 to the feeding rod 421.
