[0019] The present invention is further described in detail below with reference to the accompanying drawings and specific implementation modes. DETAILED DESCRIPTION

[0020] like Figures 1 to 4 As shown, this embodiment provides a hang tag string threading and knotting device, comprising a winding and unwinding mechanism 100, a rope pulling mechanism 200, a knotting mechanism 300 and a cutting mechanism 400. The winding and unwinding mechanism 100 is used for string threading, the rope pulling mechanism 200 is used for pulling the hanging rope for knotting, the knotting mechanism 300 is used for knotting the hanging rope, and the cutting mechanism 400 is used for cutting the hanging rope that has been threaded with the hang tag and tied.

[0021] The winding mechanism 100 includes a rope feeding assembly, a rope feeding needle 110 and a first clamping assembly 120. The rope feeding assembly transmits the rope to the rope feeding needle 110. The rope feeding needle 110 is used to move back and forth so as to insert the rope into the through hole of the hangtag. The first clamping assembly 120 is used to clamp or loosen the end of the rope inserted into the hangtag, so that when the rope pulling mechanism 200 clamps the hangtag and moves, the ropes on both sides of the hangtag can move with the rope pulling mechanism 200 and contact the knotting mechanism 300, and the ropes on either side or both sides of the hangtag can be knotted as needed.

[0022] Specifically, the winding mechanism 100 further includes a rope roll placement rack 130, a rope reversing pipe 140, a driving wheel 150 and a guide wheel 160. The rope roll placement rack 130 is used to place the wound rope. The rope reversing pipe 140 allows the rope to pass through and directs the rope toward the driving wheel 150 to prevent the rope from slipping off the driving wheel 150 due to the rope pulling out direction being different from the driving wheel 150. The driving wheel 150 is used to drive the rope coming out of the rope annular pipe 140 to move. The guide wheel 160 allows the rope coming out of the driving wheel 150 to bypass. After passing through the guide wheel 160, the rope extends to the rope feeding needle 110. The guide wheel 160 is preferably a ceramic guide wheel, which has the advantages of smooth surface and wear resistance.

[0023] Specifically, the unwinding mechanism 100 also includes a driven wheel 151, which is located on one side of the driving wheel 150. The rope passes between the driving wheel 150 and the driven wheel 151. The driven wheel 151 is used to press the rope toward the driving wheel 150 to prevent the rope from sliding on the driving wheel 150 and being unable to be moved by the driving wheel 150.

[0024] Specifically, the guide wheel 160 includes an upper guide wheel group 161, a lower guide wheel group 162 and a lower guide wheel group driving member 163. The lower guide wheel group 162 has one less guide wheel than the upper guide wheel group 161. The lower guide wheel group driving member 163 is used to drive the lower guide wheel group 162 to move up and down. When the rope feeding needle 110 passes the hanging rope through the hangtag or the rope pulling mechanism 200 pulls the hanging rope, the lower guide wheel group driving member 163 can drive the lower guide wheel group 162 to move upward to cooperate with the rope pulling, play a buffering role, reduce the pressure of the driving wheel 150 to move the hanging rope, and when the hanging rope is not pulled or the pulling speed is slow, the lower guide wheel group driving member 163 can drive the lower guide wheel group 162 to move downward, play a role in storing the hanging rope. The hanging rope coming out of the driving wheel 150 passes through the guide wheels of the upper guide wheel group 161 and the guide wheels of the lower guide wheel group 162 alternately in sequence, and then extends from the upper guide wheel group 161 to the rope feeding needle 110.

[0025] Specifically, the winding and unwinding mechanism 100 further includes a main mounting plate 170, a first support plate 171, a second support plate 172, a telescopic driving member 173 and a clamping driving member 174. The main mounting plate 170 is vertically arranged, and the rope reversing pipe 140, the driving wheel 150, the driven wheel 151, the guide wheel 160, and the telescopic driving member 173 are installed on the side of the main mounting plate 170. The second support plate 172 is connected to the main mounting plate 170, and the clamping driving member 174 is installed on the second support plate 172. The clamping driving member 172 is used to drive the first clamping assembly 120 to clamp or release. The opening of the first clamping assembly 120 is upward and aligned with the rope feeding needle 110. The rope feeding needle 110 is installed on the first support plate 171, and the telescopic driving member 173 is used to drive the first support plate 171 to move up and down.

[0026] The rope pulling mechanism 200 includes a first driving assembly 210, a second driving assembly 220 and a second clamping assembly 230. The second driving assembly 220 is connected to the first driving assembly 210, and the first driving assembly 210 is used to drive the second driving assembly 220 to move in a first direction, and the first direction is, for example, a horizontal direction. The second clamping assembly 230 is connected to the second driving assembly 220, and the second driving assembly 220 is used to drive the second clamping assembly 230 to move in a second direction, and the second direction is perpendicular to the first direction, and the second direction is, for example, a vertical direction. The second clamping assembly 230 is used to clamp or release the hangtag. When the hangtag is inserted into the hangtag and the second clamping assembly 230 clamps the hangtag, the movement of the first driving assembly 210 and / or the second driving assembly 220 can drive the hangtag to move. The second clamping assembly 230 can clamp a horizontally placed hangtag from top to bottom. The hangtag may be a single hangtag or a hangtag group in which multiple hangtags are stacked and placed in a manner in which the through holes are aligned. The hangtag may be moved by the rope pulling mechanism 200 to a rope threading position corresponding to the rope feeding needle 110.

[0027] The knotting mechanism 300 includes a third driving assembly 310, a rotating driving member 320 and a knotting kit 330. The rotating driving member 320 is connected to the third driving assembly 310. The third driving assembly 310 is used to drive the rotating driving member 320 to move along a third direction, which is perpendicular to the first direction and the second direction. The knotting kit 330 is connected to the rotating driving member 320. The knotting kit 330 includes a pointed rotating chuck 331. The rotating driving member 320 is used to drive the rotating chuck 331 to rotate. When the first driving assembly 210 and / or the second driving assembly 220 moves and drives the suspension rope to move, the suspension rope can be wound around the outer side of the rotating chuck 320 as the rotating chuck 320 rotates, and the rotating chuck 320 can clamp the outer end of the suspension rope loop as the rotating chuck rotates, and then the suspension rope loop can be detached from the rotating chuck 320. The rotating chuck 320 then loosens the outer end of the loop as the rotating chuck 320 rotates to form a rope knot. The detachment of the rope loop from the rotating clamp 320 can be achieved by the third driving assembly 310 driving the knotting kit 330 to retreat.

[0028] Specifically, the rotary drive member 320 includes a mounting seat 321 and a motor 322. The motor 322 and the knotting kit 330 are mounted on the mounting seat 321. The motor 322 is connected to the first gear 323. The knotting kit 330 is connected to the second gear 332, the third gear 333 and the fourth gear 334. The second gear 332 is meshed with the first gear 323. The second gear 332 is connected to the third gear 333 in a circumferential linkage. The fourth gear 334 is meshed with the third gear 333. The fourth gear 334 is connected to the rotating chuck 331 in a circumferential linkage. The third gear 333 and the fourth gear 334 are both bevel gears, which can change the direction of the rotating chuck 331 relative to the first gear 323.

[0029] Specifically, the first gear 323 is connected with an inductive switch plate 324, and the mounting seat 321 is also provided with an inductive switch mounting bracket 325 for cooperating with the inductive switch plate 324. The inductive switch mounting bracket 325 is used to install an inductive switch, and the inductive switch is used to detect the rotation of the inductive switch plate 324 and control the on and off of the motor 322, so as to better control the rotation of the motor 322 and the rotating chuck 331 driven by the motor 322.

[0030] Specifically, the knotting kit 330 further includes a main body 335 and a clamp looseness switch 336, and the clamp looseness switch 336 and the rotating clamp 331 are rotatably connected to the main body 335. The clamp looseness switch 336 includes a knob 337 and a first protrusion 338 connected to the knob 337, and the first protrusion 338 always abuts against one side of the rotating clamp 336, for example, under the action of the elastic force provided by a spring, the first protrusion 338 is pressed toward one side of the rotating clamp 336. The end of the rotating clamp 336 includes a second protrusion 339, and the second protrusion 339 is used to push the first protrusion 338 to move and thus rotate the knob 337, and the rotating clamp 336 is loosened or clamped as the knob 336 rotates. For example, the knob 336 and the two clamping blocks of the rotating chuck 336 can be connected by a transmission connection such as a pawl, a ratchet, or a cam. Each time the second protrusion 339 pushes the first protrusion 338, the knob 336 drives the pawl to slide. After the second protrusion 339 is rotated and removed, the knob 336 and the first protrusion 338 can be restored to their original positions under the action of the spring force, so that the ratchet in or on the main body 335 moves one grid, and the ratchet drives the cam circumferentially linked with it to rotate one grid. The cam is adjacent to a clamping block of the rotating chuck 336, and the cam is alternately provided with protrusions and recesses on different grids, so that when it rotates to a certain grid, the protrusion of the cam can push one clamping block of the rotating chuck 336 toward another clamping block, thereby achieving the clamping of the rotating chuck 336. When it rotates to the next grid, the recess of the cam can release the force that pushes one clamping block of the rotating chuck 336 toward another clamping block, so that the two clamping blocks can be loosened, for example, under the action of the spring force. The structure for achieving loosening or clamping of the rotating chuck 336 as the knob 336 rotates is not limited to the above examples, as long as the two clamping blocks of the rotating chuck 336 can be clamped or loosened when the knob 336 completes one rotation and reset.

[0031] The cutting mechanism 400 is located between the winding mechanism 100 and the knotting mechanism 300, and is used to cut the hanging rope between the hanging tag and the rope feeding needle 110. The cutting mechanism 400 also includes a pneumatic scissors 410 that can cut and loosen, and a scissors moving driving member 420, and the scissors moving driving member 420 is used to drive the pneumatic scissors 410 to move along the third direction. The pneumatic scissors 410 can extend to cut the hanging rope, and can also retract to avoid accidentally touching the hanging rope.

[0032] Specifically, the tag stringing and knotting device also includes a workbench, the winding mechanism 100, the first drive assembly 210 and the third drive assembly 310 are installed on the workbench, and the scissors moving drive member 420 is installed on the main mounting plate 170 of the winding mechanism 100 or the workbench.

[0033] Based on the device of this embodiment, a method for threading a tag rope and tying a knot can be implemented, and the method comprises the following steps:

[0034] Step 1, move the hangtag to a position where the through hole of the hangtag is aligned with the rope feeding needle 110, the hangtag being a single hangtag or a hangtag group formed by stacking multiple hangtags;

[0035] Step 2: The rope feeding needle 110 moves into the through hole to pass the end of the hanging rope through the hangtag, and then the rope feeding needle 110 moves out, and the first clamping assembly 120 clamps the end of the hanging rope;

[0036] In step three, the rope pulling mechanism 200 drives the tag to move, and the third driving assembly 310 drives the knotting kit 330 to move, so that the ropes on either side or both sides of the tag contact with the rotating chuck 331, and the rotating driving member 320 drives the rotating chuck 331 to rotate, thereby knotting the ropes on either side or both sides of the tag.

[0037] Finally, it should be emphasized that the above 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.
