[0029] When bundling, the head of the cable tie is fixed in the positioning hole 23; the tail of the cable tie passes through the hole 63 of the head of the cable tie under the guidance of the material loading guide mechanism 3, and passes through the tensioning mechanism 4, and the material is tied tightly under the pulling of the tensioning mechanism 4.

[0030] The cutting mechanism 5 of the present technical solution is located between the slot plate 21 and the tensioning mechanism 4, and the cutter 51 is close to the slot plate 21 for cutting, which can cut the tail passing through the hole as much as possible, reduce the exposure of the tail of the cable tie, prevent scratches, and improve the aesthetics of the bundling effect.

[0031] The front end of the positioning hole 23 is provided with a positioning groove 231 for accommodating the head 61 of the cable tie; the lower edge of the rear end of the positioning hole 23 is provided with a fixed cutting edge 232; the cutter 51 is provided with a movable cutting edge 511; when the cutter 51 moves downward, the movable cutting edge 511 can collide with the fixed cutting edge 232 to cut the tail of the cable tie.

[0033] A guide groove 24 extending from top to bottom to the positioning hole 23 is provided on the back of the groove plate 21 . The cutter 51 is located in the guide groove 24 and moves up and down along the guide groove 24 , and is stable and does not deviate.

[0034] The material loading guide mechanism 3 includes an upper guide member 31 , a lower guide member 32 and a material loading plate 33 .

[0035] The material loading plate 33 is located below the output end of the feed trough 22 ; a material loading platform 331 is provided on the material loading plate 33 for placing the materials to be bundled; a lower guide groove 332 is provided in the middle of the material loading platform 331 .

[0041] like Figure 3-5 As shown, the working principle of this technical solution is as follows:

[0042] 1. Place the materials to be bundled on the loading platform 331;

[0043] 2. The tail of the cable tie is directed downwards into the feed trough 22 from the input end of the feed trough 22;

[0044] 3. The cable tie slides down along the feed trough 22 to its output end, the head of the cable tie falls into the positioning groove 231 of the positioning hole 23, and the tail of the cable tie enters the lower guide groove 332, and bends upward under the guidance of the arc-shaped hook portion 321 of the lower guide member 32;

[0045] 4. When the upper guide member 31 slides down the cable tie, it moves down to the front end of the positioning hole 23; when the tail of the cable tie bends upward until it contacts the upper guide groove 311, it is guided to turn and bend backward;

[0046] 5. The lower guide member 32 rotates to lift the arc-shaped hook portion 321 upward, driving the tail of the cable tie to continue to curl upward and backward to be inserted into the tie hole of the cable tie, and inserted into the gap between the upper rotating wheel 41 and the lower rotating wheel 42;

[0047] 6. Under the clamping force of the rotating upper wheel 41 and the lower wheel 42, the tail of the cable tie is pulled toward the rear of the slot plate 21 to tighten the cable tie;

[0048] 7. The cutter 51 of the cutting mechanism 5 moves downward to cut off the excess tail of the cable tie.

[0049] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme.
