[0051] The first arc groove 143, the second arc groove 154 and the material stringing channel 70 are sequentially arranged from top to bottom along the same vertical line.

[0052] In this embodiment, the first driving member 110, the second driving member 120 and the third driving member 153 all adopt cylinders, and of course other conventional technical means in the field may also be adopted, such as servo motors, linear guide rails and other structures; the first elastic member 66, the second elastic member 67, the third elastic member 55 and the fourth elastic member 32 all adopt springs, and of course other conventional technical means in the field may also be adopted, such as elastic rubber and the like.

[0053] The working principle of the present invention is briefly described below in combination with the contents of Embodiment 1 and Embodiment 2.

[0054] When the present invention is used, the bamboo skewers to be bundled are first placed between the upper feeding assembly 140 and the lower feeding assembly 150, and the feeding action can be completed manually or mechanically. The upper feeding assembly 140 is driven downward by the first driving member 110, thereby driving the bamboo skewers to move downward; under the retraction action of the upper feeding buckle 142 and the first feeding clamp arm 151 and the second feeding clamp arm 152, and as the upper feeding assembly 140 continues to move downward, the bamboo skewers are gathered in the circular groove formed by the first arc groove 143 and the second arc groove 154. At this time, the second driving member 120 begins to move downward. Since the first driving member 110 is set on the positioning plate 130 and the second driving member 120 is connected to the positioning plate 130, the second driving member 120 will simultaneously drive the positioning plate 130 and the first driving member 110 to move downward synchronously.

[0055] Driven by the second driving member 120, the stringing bamboo skewer moves toward the stringing channel 70 and first contacts the tape on the tape guide wheel 40; as the second driving member 120 continues to move, the stringing bamboo skewer continues to move downward, and presses down the guide blade 42 to drive the tape guide wheel 40 to rotate, and during the rotation of the tape guide wheel 40, the tape is wrapped around the outside of the stringing bamboo skewer.

[0056] The second driving member 120 continues to drive the string bamboo skewer to move downward, and further presses down the front end of the tape limiting member 30, and the front end of the tape limiting member 30 rotates clockwise to press the two ends of the tape wrapped around the string bamboo skewer together.

[0057] The tape-wrapped bamboo skewer continues to move downward and further presses down the first extension arm 52 of the tape cutting member 50, and the tape cutting member 50 rotates around the third rotating shaft 51 and drives the second extension arm 53 and the cutting knife 54 to move into the material stringing channel 70, thereby cutting the tape.

[0058] The stringing bamboo skewer continues to move downward and further presses down the second arc-shaped arm 64 of the binding piece 60. Under the action of the first elastic piece 66 and the fourth rotating shaft 61, the binding piece 60 moves downward and rotates around the fourth rotating shaft 61, so that the first arc-shaped arm 63 contacts the stringing bamboo skewer from above and rotates around the upper part of the stringing bamboo skewer, thereby wrapping the cut excess tape around the stringing bamboo skewer.

[0059] The second driving member 120 continues to drive the stringing bamboo skewers to move downward. When the stringing bamboo skewers are completely separated from the bundling member 60, the second driving member 120 stops moving. At this time, the third driving member 153 starts to move, driving the first rotating arm 155 and the second rotating arm 156 to rotate clockwise around the fifth rotating shaft 157, so that the end of the second arc groove 154 is separated from the first feeding clamp arm 151. When the distance between the second arc groove 154 and the first feeding clamp arm 151 is large enough, the stringing bamboo skewers will separate from the second arc groove 154, and fall downward along the stringing channel 70, and finally fall into the material receiving device below the stringing channel 70 (not shown in the figure).

[0060] After the above series of actions are completed, the first driving member 110 and the second driving member 120 are reset to prepare for the next action.

[0061] The string material bundling device of the present invention can continue to wrap the tape whose two ends have been stuck together around the bamboo sticks through the mutual cooperation of the first driving member 110, the second driving member 120, the tape stopper 30, the tape guide wheel 40, the tape cutting member 50 and the bundling member 60, so that the excess part of the tape is stuck to the outer wall of the bamboo stick, and finally all the tape is wrapped around the outer side of the bamboo stick, thereby improving the bundling strength of the bamboo sticks and preventing the problem of the string material from being scattered easily; Figure 5 Shown is a schematic diagram of the bundled bamboo skewers of the present invention.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
