Referring to fig. 3, the rack assembly 410 includes a rack main body 411 and a connecting plate 413, the connecting plate 413 is connected to the rack main body 411 and connects the rack main body 411 to the second rotating module 300, so as to connect the rack assembly 410 to the second rotating module 300.

In this embodiment, the gun rest body 411 is generally a tube, and the gun rest body 411 may include first and

second mounting plates

4111, 4113 that are spaced apart from each other, with the first and

second mounting plates

The accommodation cavity 401 is disposed between the first mounting plate 4111 and the second mounting plate 4113, and is used for accommodating the wire feeding assembly 430 and the wire feeding transmission assembly 470, so that the structure of the banding gun 400 is compact.

In this embodiment, the gun rack main body 411 is used to protect the wire feeding assembly 430 and the wire feeding transmission assembly 470 in the accommodating cavity 401, so as to avoid damage to the wire feeding assembly 430 and the wire feeding transmission assembly 470 in the gun rack main body 411 due to external impact, and meanwhile avoid direct exposure of the wire feeding assembly 430 and the wire feeding transmission assembly 470 and influence of the environment (such as particles, water, etc.).

The connecting plate 413 is connected to one end of the gun rack main body 411 and is provided with a wire feeding hole 4131 communicated with the accommodating cavity 401, so that the binding wire 530 enters the accommodating cavity 401 from the wire feeding hole 4131.

Referring to fig. 4, the wire feeding assembly 430 includes a wire feeding member 431, a first wire guiding tube 433 and a second wire guiding tube 435, wherein the first wire guiding tube 433 and the second wire guiding tube 435 are connected to two ends of the wire feeding member 431. The first guide wire tube 433 is perforated with a wire feed hole 4131 so that the binding wire 530 can enter the binding gun 400 via the first guide wire tube 433. The wire feeder 431 is used to guide the binding wire 530 entering the first guidewire tube 433 to the second guidewire tube 435.

In the present embodiment, the first guide wire tube 433 and the second guide wire tube 435 may have a tubular shape for guiding the binding wire 530 into the banding gun 400 via the first guide wire tube 433 and the second guide wire tube 435, thereby achieving wire feeding of the banding gun 400.

The wire feeding member 431 includes a wire feeding wheel 4315, the wire feeding wheel 4315 is connected between the first wire guiding pipe 433 and the second wire guiding pipe 435, and the wire feeding wheel 4315 is disposed on the wire feeding transmission assembly 470 for conveying the binding wire 530 under the driving of the wire feeding transmission assembly 470. As an embodiment, the wire feeding wheel 4315 may be provided with a wire feeding groove into which the binding wire 530 passed through the first wire guiding tube 433 enters. When the thread feeding wheel 4315 moves, the binding thread 530 moves from the thread feeding groove to the second thread guide 435 with the movement of the thread feeding wheel 4351, so that the binding thread 530 can move from the first thread guide 433 to the second thread guide 435.

Further, the wire feeding member 431 further includes a connecting shaft 4311 and a first gear 4313, and the first gear 4313 and the wire feeding wheel 4315 are sleeved on the connecting shaft 4311. In this embodiment, when the first gear 4313 rotates, it drives the yarn feeding wheel 4315 to rotate via the connection shaft 4311, thereby guiding the binding yarn 530 from the first yarn guiding tube 433 to the second yarn guiding tube 435. The wire feeding wheel 4315 can be driven to rotate by driving the first gear 4313, so that the binding wire 530 is moved, the wire feeding member 431 has a compact structure, and the space occupation of the accommodating cavity 401 is saved.

Further, the wire feeding member 431 further includes a one-way bearing (not shown) disposed on the connecting shaft 4311 to limit the first gear 4313 to rotate the connecting shaft 4311 only along a predetermined direction. Therefore, if the first gear 4313 drives the connecting shaft 4311 to rotate in a predetermined direction, the wire feeding wheel 4315 can feed the wire 530. If the first gear 4313 drives the connecting shaft 4311 to rotate in a non-predetermined direction, the one-way bearing slips to make the wire feeding wheel 4315 stationary, and the wire 530 cannot be fed.

As an embodiment, a driving device (e.g., a driving motor, etc.) for driving the first gear 4313 may have two rotating directions, wherein the wire feeding wheel 4315 feeds the binding wire 530 in one rotating direction, and the wire feeding wheel 4315 does not feed the binding wire in the other rotating direction. This drive arrangement can realize other functions of ligature rifle 400 through another direction of rotation to, set up a drive arrangement and can realize sending a silk and other functions of ligature rifle 400, realize having simplified the effect of ligature rifle 400 structure.

A kinking wire assembly 450 is connected to the end of the holster body 411 remote from the connection plate 413 and is connected to the second guide wire tube 435 in order to kink the binding wire 530 fed through the second guide wire tube 435. In the present embodiment, the kinking operation means that the straight tying wire 530 is changed into the arc-shaped tying wire 530, so that the arc-shaped tying wire 530 formed by continuously passing through the kinking wire assembly 450 can form the circle-shaped tying wire 530.

Specifically, referring to fig. 5, the wire bending assembly 450 includes a first guide member 451, a wire bending member 453 and a second guide member 455, the first guide member 451 and the second guide member 455 are disposed at the same end of the gun rack body 411 at intervals, and the wire bending member 453 is connected to the first guide member 451.

The first guide member 451 is provided with a binding passage 4511, the binding passage 4511 is connected to the second guide wire duct 435, and the binding wire 530 passes through the second guide wire duct 435 to enter the binding passage 4511 of the first guide member 451.

The kinking member 453 is provided with an arc-shaped groove (not shown) which is communicated with the kinking channel so that the kinking 530 entering the kinking member 453 through the second thread guide tube 435 and the first guide member 451 can be changed into an arc shape from a straight state through the kinking member 453. In the present embodiment, when the straight binding wire 530 passes through the arc-shaped groove, the binding wire 530 is bent under the guidance of the arc-shaped groove by receiving an external force (wire feeding force/pushing force from the wire feeding roller 4315), thereby forming an arc-shaped binding wire 530. It should be noted that the tying wire 530 is kinked in a direction toward the first guide member 453, i.e., the center of the arcuate tying wire 530 is generally located in a direction toward the first guide member 451 from the kinked wire member 453.

The second guide 455 includes two guide tabs 4551, the two guide tabs 4551 being angularly connected and forming a guide slot 4501 facing the first guide 451 to guide the binding wire 530 entering the second guide 455 through the wire kink member 453. Since the binding wire 530 passing through the wire-bending member 453 is arc-shaped, the arc-shaped binding wire 530 moves along the guide of the guide groove 4501 under the action of an external force (wire feeding force from the wire feeding wheel 4315). Since the binding wires 530 passing through the wire bending member 453 are all bent toward the first guide member 451, the binding wire 530 moving along the guide groove 4501 is also bent toward the first guide member 451, thereby forming a substantially circular shape of the binding wire 530. It should be noted that the second guide member 455 is used to provide load bearing and guidance for the arcuate binding wire 530 to facilitate the formation of the loop-shaped binding wire 530.

In use, the free end of the binding wire 530 enters the first guide member 451 through the second guide wire tube 435, and is bound to the arc-shaped binding wire 530 by the wire binding member 453, and the arc-shaped binding wire 530 is bent downward by the guide groove 4501 of the second guide member 455, so as to form the circle-shaped binding wire 530 between the first guide member 451 and the second guide member 455. It should be noted that, during the binding gun 400, the round wire 530 is disposed around the reinforcing bars to facilitate the binding of the reinforcing bars.

Referring to fig. 6, the wire feeding driving assembly 470 includes a second gear 471, a transmission shaft 473 and a motor 475, the second gear 471 is sleeved on the transmission shaft 473, and the transmission shaft 473 is connected to the motor 475. In this embodiment, the motor 475 is disposed at an end of the gun rack main body 411 close to the connecting plate 413, an end of the transmission shaft 473 away from the motor 475 faces an end of the gun rack main body 411 away from the connecting plate 413, and the motor 475 is configured to drive the transmission shaft 473 to rotate. The motor 475 may be fixed to the gun rack main body 411 by a structure of a motor base.

Further, the second gear 471 is meshed with the first gear 4313, and when the motor 475 drives the transmission shaft 473 to rotate, the second gear 471 can drive the first gear 4313 to rotate, so as to realize the wire feeding of the wire feeding member 431. In this implementation, the motor 475 may be powered by an external power source, thereby improving the range of the banding gun 400.

Specifically, the second gear 471 and the first gear 4313 are bevel gears, and are engaged with the first gear 4313 through the second gear 471, and when the transmission shaft 473 drives the second gear 471 to rotate, the first gear 4313 engaged with the second gear 471 also rotates, so that the connecting shaft 473 connected with the first gear 4313 rotates and drives the wire feeding wheel 4135 to rotate, thereby realizing the wire feeding of the wire feeding member 431. In one embodiment, the second gear 471 is substantially perpendicular to the first gear 4313, i.e., the transmission shaft 473 is substantially perpendicular to the connection shaft 4311. The connecting shaft 4311 perpendicular to the transmission shaft 473 is arranged, so that the structure of the binding gun 400 is compact, and the floor area of the binding gun 400 is reduced. In some embodiments, the second gear 471 and the first gear 4313 may be both cylindrical spur gears, and the transmission between the wire feeding drive assembly 470 and the wire feeding member 431 is realized by the engagement of the first gear 471 and the second gear 4313.

Wire feed drive assembly 470 further includes an actuator 477, actuator 477 being coupled to an end of drive shaft 473 opposite motor 475. In this embodiment, the actuator 477 may be an air claw, the actuator 477 includes an actuator body 4771 and a clamp portion 4773, the actuator body 4771 is connected between the clamp portion 4773 and the transmission shaft 473, and the actuator body 4771 can control the clamp portion 4773 to open or close by the rotation direction of the transmission shaft 473.

In one embodiment, when the motor 475 rotates forward, the wire feeding transmission assembly 470 is in a wire feeding state, the actuator body 4771 controls the clamp portion 4773 to be in an open state, and the clamp portion 4773 in the open state has an opening degree of approximately 180 °, so that the binding wire 530 can normally pass through the clamp portion 4773 when the clamp portion 4773 rotates along with the transmission shaft 473 under the driving of the actuator body 4771. When the motor 475 rotates reversely, the wire feeding drive assembly 470 is in a twisted state, the actuator body 4771 controls the clamp portion 4773 to be in a closed state, and the clamp portion 4773 in the closed state clamps the binding wire 530 passing through the clamp portion 4773 and twists the binding wire 530 by the drive shaft 473. The round wire 530 is tightened by the force of the clamp 4773, so that the reinforcement bar can be bound and fixed.

It should be noted that the wire feeding member 431 is provided with the one-way bearing as described above, when the wire feeding transmission assembly 470 is in the wire feeding state, the motor rotates forward, the first gear 4313 rotates clockwise through the transmission of the transmission shaft 473, the first gear 4313 drives the one-way bearing and the wire feeding wheel 4315 to rotate via the connection shaft 4311, and the wire feeding member 431 normally feeds the wire. When the wire feeding transmission assembly 470 is in a wire twisting state, the motor rotates reversely, the first gear 4313 rotates counterclockwise through the transmission of the transmission shaft 473, and when the first gear 4313 drives the one-way bearing via the connection shaft 4311, the one-way bearing slips to keep the wire feeding wheel 4315 static, so the wire feeding piece 431 does not feed wires, and the wire tying 530 does not move when the clamping part 4773 twists the wires, so the wire feeding transmission assembly 470 can complete the two functions of wire feeding and wire twisting, and the structure of the binding gun 400 is simplified.

Further, the motor 475 may be provided with a torque detection module (not shown) for detecting a torque of the actuator 477 tightening the binding wire 530. For example, can predetermine the moment of torsion of twisting tight to tying wire 530, rethread moment of torsion detects the module and detects clamping part 4773 and twist tight moment of torsion to tying wire 530 to when carrying out the ligature to the reinforcing bar of different specifications, it is unanimous to tie the tight degree of torsion of wire 530 to the reinforcing bar, thereby the fixed effect of guarantee tying wire 530 to the reinforcing bar.
