[0026] The process of the transfer driver 22 driving the transfer rack 21 to rotate includes a transfer loading state when the transfer rod 211 is docked with the dental floss rack, and a transfer unloading state when the transfer rod 211 is docked with the feeding rod 31; Figure 2 As shown, the dental floss rack is in a comb shape and includes multiple dental floss rods, each of which is hung with a number of dental floss sticks. When the transfer rod 211 is in the transfer loading state, one end of the transfer rod 211 abuts against one end of a dental floss rod, and the transfer rod 211 is coaxially arranged with the dental floss rod; when the transfer rod 211 is in the transfer unloading state, one end of the transfer rod 211 abuts against one end of the feeding rod 31, and the transfer rod 211 is coaxially arranged with the feeding rod 31.

[0027] The process of the X-axis feeding drive 32 driving the feeding rod 31 to slide back and forth includes a feeding loading state when the feeding rod 31 is docked with the transfer rod 211, and a feeding unloading state when the dental floss stick on the feeding rod 31 corresponds to a packaging box or bag. When the feeding rod 31 is in the feeding loading state, one end of the feeding rod 31 abuts against one end of the transfer rod 211, and the transfer rod 211 is coaxially arranged with the feeding rod 31; when the feeding rod 31 is in the feeding unloading state, the dental floss stick on the feeding rod 31 can be put into the packaging box or bag.

[0028] When the transfer rod 211 is in the transfer loading state, the end of the transfer rod 211 will dock with the dental floss material rack, and the rotating paddle driver 24 can drive the transfer paddle 23 to push the dental floss stick on the dental floss material rack onto the transfer rod 211, and then the rotating paddle driver 24 will drive the transfer paddle 23 to reset and slide, and at the same time, the transfer driver 22 intermittently drives the transfer rack 21 to rotate so that the transfer rod 211 is in the transfer unloading state and pauses, and then the X-axis feeding driver 32 drives the feeding rod 31 to be in the feeding loading state, so that the end of the feeding rod 31 will dock with the end of the transfer rod 211, and the feeding paddle driver 34 can drive the feeding paddle 33 to push the dental floss stick on the transfer rod 211 onto the feeding rod 31, and then the feeding paddle driver 34 will drive the feeding paddle 33 to reset and slide, and at the same time, the X-axis feeding driver 32 drives the feeding rod 31 to slide to the feeding unloading state, and then cooperate with the instruction manual attached Figure 2 The side baffle at the opening of the middle packaging box or bag will drop the dental floss stick on the feeding rod 31, so that automatic feeding of the dental floss stick becomes possible, thereby achieving full automation, which is beneficial to improving production efficiency and reducing labor costs.

[0029] At least two transfer rods 211 are provided, and the number of transfer rods 211 is an even number, and two transfer rods 211 form a group, and when one transfer rod 211 of a group is in the transfer loading state, the other transfer rod 211 is in the transfer unloading state. The provision of the two transfer rods 211 enables one transfer rod 211 to be in the transfer loading state while the other transfer rod 211 is in the transfer unloading state, so that the transfer component 2 can simultaneously realize the loading and unloading of the dental floss stick, which is conducive to improving production efficiency.

[0030] If two or three sets of transfer rods 211 are provided, the rotation angle of the transfer frame 21 can be further reduced, thereby further improving production efficiency.

[0031] The transfer component 2 also includes a limiting rod 25 that can prevent the dental floss stick on the transfer rod 211 from falling off. The limiting rod 25 is bent into a C-shaped structure, and one end of the limiting rod 25 is corresponding to the transfer rod 211 in the transfer loading state, and the other end is corresponding to the transfer rod 211 in the transfer unloading state. The shape of the limiting rod 25 is similar to the rotation trajectory of the outer end of the transfer rod 211, which can effectively prevent the dental floss stick on the transfer rod 211 from being thrown off during the rotation of the transfer frame 21.

[0032] The feeding component 3 also includes a rotating feeding driver 35 capable of driving the feeding rod 31 to rotate axially, and the feeding rod 31 is provided with a rotation limiting structure capable of limiting the rotation of the dental floss stick on the feeding rod 31. Since the dental floss stick is large at one end and small at the other end, similar to the number 9, when the dental floss stick is put into a packaging box or bag, the feeding driver 35 can be rotated to drive the feeding rod 31 to rotate axially, thereby adjusting the posture of the dental floss stick when dropping, and then facilitating the packing of multiple groups of dental floss sticks into a packaging box or bag in a 69 pattern, which effectively improves the use flexibility and application scope of the feeding device, and also greatly improves the automation of the feeding device.

[0033] A rotation limiting plane 311 is provided on the outer side wall of the feeding rod 31 along the length direction thereof, which can limit the rotation of the dental floss stick on the feeding rod 31. The cross section of the feeding rod 31 along the length direction thereof is provided in a D-shaped structure. The outer contour of the larger end of the dental floss stick is in a D-shaped structure. After the feeding rod 31 passes through the hole at the larger end of the dental floss stick, the dental floss corresponds to the rotation limiting plane 311, thereby preventing the dental floss stick from rotating on the feeding rod 31 when the feeding rod 31 drives the dental floss stick to rotate.

[0034] The end of the delivery rod 31 is provided with a slot 312 for inserting the end of the transfer rod 211. The slot 312 can be inserted into the end of the transfer rod 211, which not only improves the stability of the delivery rod 31 and the transfer rod 211 when they are connected, but also facilitates the smooth transfer of the dental floss stick on the transfer rod 211 to the delivery rod 31.

[0035] The rotation limiting structure includes a rotation limiting rod 313 arranged parallel to the feeding rod 31, and the distance between the feeding rod 31 and the rotation limiting rod 313 is smaller than the length of the dental floss stick. Figure 4 As shown, the rotation limiting rod 313 is parallel to the feeding rod 31. After the feeding rod 31 with a smaller outer diameter passes through the dental floss stick, the rotation limiting rod 313 can rotate along with the feeding driver 35 to drive the feeding rod 31 to rotate axially, thereby dragging the tail end of the dental floss stick to adjust its posture.

[0036] The transfer component 2 further includes a transfer support 26 for adjusting the inclination angle of the dental floss stick, and the transfer support 26 is located below the transfer rod 211 in the transfer unloading state. The gap between the transfer support 26 and the transfer rod 211 determines the inclination angle of the dental floss stick at that location, and by adjusting the gap between the transfer support 26 and the transfer rod 211, the inclination angle of the dental floss stick at that location is adapted to the rotation-limiting structure on the feeding rod 31, thereby facilitating the stability of the dental floss stick during the transfer from the transfer rod 211 to the feeding rod 31.

[0037] The main frame 1 is provided with a counting probe 4 for counting dental floss sticks, and the counting probe 4 is located above the transfer rod 211 when the material is in the transfer unloading state. The counting probe 4 is a well-known technology, and adopts a common design, and can be used to count the dental floss sticks on the transfer rod 211, so as to count the number of dental floss sticks put into the packaging box or bag. If the number of dental floss sticks on the transfer rod 211 is less than the set value, after the current delivery step is completed, the small amount of packaging boxes or bags can be rejected in the subsequent output of the assembly line.

[0038] The feeding component 3 also includes a Y-direction feeding driver 36 capable of driving the feeding rod 31 to slide back and forth in the Y direction, and a Z-direction feeding driver 37 capable of driving the feeding rod 31 to slide back and forth in the Z direction. The X-direction feeding driver 32, the Y-direction feeding driver 36 and the Z-direction feeding driver 37 can respectively perform three-dimensional regulation on the feeding rod 31 in three directions, which greatly improves the flexibility and application range of the feeding rod 31, and can conveniently feed the dental floss stick into a packaging box or bag through the various-direction feeding drivers.

[0039] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
