The feeding transmission belt is rotatably connected to the main frame 1. The transmission connection between the feeding motor 3 and the feeding transmission belt is a well-known technology and adopts a common design. In this application, the feeding transmission belt preferably adopts a belt structure. The clamping manipulator 2 and the feeding transmission belt are detachably connected. In the process of the feeding motor 3 driving the feeding transmission belt to rotate, the clamping manipulator 2 can be driven to slide back and forth quickly between the loading position and the unloading position on the main frame 1. When the clamping manipulator 2 is at the unloading position, the feeding motor 3 can drive the clamping manipulator 2 to move intermittently in a directional manner.

When the clamping manipulator 2 is at the unloading position, the subsequent device can move the dental floss on the dental floss rack into 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 receives multiple dental flosses. When the first dental floss rack After all the dental floss on the material rod has been transferred into the dental floss box, the feeding motor 3 can drive the clamping robot 2 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 subsequent device, which is convenient for transferring the dental floss on it into the dental floss box. The feeding motor 3 drives the clamping robot 2 to repeat intermittent movement until all the dental floss on the dental floss rack has been transferred into the dental floss box, thereby making automatic feeding of the dental floss rack possible, thereby realizing full automation, which is conducive to improving production efficiency and reducing labor costs.

[0018] The clamping manipulator 2 includes a clamping slide 21 slidably connected to the main frame 1, a fixed clamping block 22 arranged on the clamping slide 21, a clamping cylinder 23 arranged on the clamping slide 21, and a movable clamping block 24 arranged on the piston rod of the clamping cylinder 23. The clamping slide 21 is detachably connected to the feeding transmission belt, and the clamping cylinder 23 drives the movable clamping block 24 to move in a direction close to or away from the fixed clamping block 22. The clamping slide 21 and the main frame 1 can realize linear sliding through the slide rail and the slide structure. The clamping slide 21 is detachably connected to the feeding transmission belt, which can not only conveniently drive the clamping slide 21 to move through the feeding transmission belt, but also conveniently realize the position adjustment of the clamping slide 21, greatly improving the use flexibility and application scope of the clamping manipulator 2, and the clamping cylinder 23 drives the movable clamping block 24 to approach or move away from the fixed clamping block 22, which can conveniently realize the floss material rack to be taken and placed.

[0019] There are multiple groups of clamping manipulators 2, and each group of clamping manipulators 2 is arranged along the sliding direction on the main frame 1. In the drawings of the present application, there are two groups of clamping manipulators 2, which can cooperate with two groups of subsequent devices to perform packaging operations at the same time, which is conducive to improving work efficiency. When in use, the first clamping manipulator 2 is located at the loading position. At this time, the loading device can convey the dental floss material rack to correspond to the first clamping manipulator 2, so that it is convenient for it to clamp the dental floss material rack, and then the feeding motor 3 drives the first clamping manipulator 2 to leave and allows the second clamping manipulator 2 to be located at the loading position. After that, the loading device conveys another dental floss material rack to correspond to the second clamping manipulator 2, so that it is convenient for it to clamp the dental floss material rack, and finally the feeding motor 3 drives the two clamping manipulators 2 to move to the lower material position.

[0020] The fixed clamp block 22 is provided with a clamping groove 221 for one end of the dental floss rack to be embedded, and the movable clamp block 24 is provided with a friction pad for increasing the friction force of clamping the dental floss rack, which is beneficial to improving the firmness of the clamping manipulator 2 clamping the dental floss rack, and further to improving the operation stability of the feeding device.
