[0028] The invention is further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the invention.

[0029] like Figure 1 and Figure 6As shown, for the convenience of description, the end provided with the guide claw 3 is defined as the front end of the cable tie machine, and the other end of the cable tie machine is defined as the rear end; a cable tie machine includes a shell 1, a frame 2 arranged on the shell 1, a guide claw 3 arranged on the frame 2 and a cable tie guide rail 4 arranged on the frame 2, the guide claw 3 includes a first guide column 31 and a second guide claw 32 respectively hinged on the frame 2 and corresponding to each other, and the cable tie guide rail 4, the first guide claw 31 and the second guide claw 32 are all provided with guide grooves 30 that cooperate with each other to guide the cable tie operation; wherein the first guide claw 31 is hooked inwardly by a push rod 5 and a cylinder 6, and the cylinder 6 drives The push rod 5 moves. Specifically, the cylinder 6 is fixed in the housing 1, and the front end of the push rod 5 is inserted into the frame 2. A through hole 51 is provided in the push rod 5, which passes through the upper and lower end surfaces thereof and can allow the tail of the cable tie to pass through. A slope extending from the front or rear of the through hole 51 to the through hole 51 is provided on the wall of the through hole 51, so as to form a cutter 7 connected to the through hole 51 at the front or rear side of the through hole 51, that is, when the slope extends from the front of the through hole 51 to the through hole 51, the cutter 7 is arranged at the front side of the through hole 51 and its blade faces backward, and when the slope extends from the rear of the through hole 51 to the through hole 51, the cutter 7 is arranged at the rear side of the through hole 51 and its blade faces forward. When the cylinder 6 drives the push rod 5 to move, it drives the first guide claw 31 to hook inward, and when the cylinder 6 is reset, it drives the push rod 5 to reset and the cutter 7 to cut the cable tie. In this embodiment, the front end of the push rod 5 is hinged to the rear end of the first guide claw 31 through a hinge hole 52, and the rear end of the push rod 5 is fixedly connected to the cylinder 6; Figure 4 As shown, the cutter 7 is arranged at the front side of the through hole 51, and the blade of the cutter 7 faces the rear side of the through hole 51. This connection structure enables the push rod 5 to drive the first guide claw 31 to hook inward when it moves forward, and the tail of the cable tie can be cut off when the push rod 5 moves backward. However, those skilled in the art should know that a connecting rod mechanism (not shown) can also be connected between the push rod 5 and the first guide claw 31, so that when the push rod 5 is driven by the cylinder 6 to move backward, it drives the first guide claw 31 to hook inward. In this case, the cutter 7 needs to be arranged at the rear side of the through hole 51 and the blade of the cutter 7 faces the front side of the through hole 51. This connection structure enables the cutter 7 to cut off the tail of the cable tie when it moves forward.

[0030] Preferably, the inclined surface passes through the upper and lower end surfaces of the push rod 5 .

[0031] Preferably, the cutter 7 and the push rod 5 may be integrally formed or the cutter 7 and the push rod 5 may be detachably connected. In order to facilitate production, in the present embodiment, the cutter 7 and the push rod 5 are integrally formed.

[0032] Preferably, a slide groove for the push rod 5 to slide is further provided in the frame 2, so that the push rod 5 will not deviate from the preset route and the push rod 5 can slide more smoothly.

[0033] like Figure 2 and Figure 3 As shown, a trigger 8 for controlling the second guide claw 32 to flip up and down is also hinged on the frame 2. Specifically, the trigger 8 is connected to the second guide claw 32 through a connecting rod. Since this connection structure is a prior art, it will not be described in detail here.

[0034] Specifically, Figure 2 and Figure 3 As shown, the cable tie machine also includes an in-place sensing mechanism; the in-place sensing mechanism includes a sensing rod 9 fixedly connected to the trigger 8 and a sensor 10 fixed on the frame 2 and used to sense the sensing rod 9. Specifically, the sensor 10 is a photoelectric sensor, and the sensing rod 9 is arranged at an angle. The specific operating principle of the in-place sensing mechanism is that when the trigger 8 is pressed upward to make the second guide claw 32 flip upward and close with the first guide claw 31, at this time, since the sensing rod 9 is fixedly connected to the trigger 8, the sensing rod 9 will move upward synchronously until the sensing rod 9 moves to the sensor 10 and is sensed by the sensor 10, and then the system controls the feeding mechanism (not shown in the figure) behind the cable tie guide rail 4 to feed the cable tie into the cable tie guide rail 4, and transport it to the first guide claw 31 and the second guide claw 32 through the cable tie guide rail 4, and then, the locking position 21 set on the frame 2 locks the head of the cable tie, and the tail of the cable tie passes through the first The guide groove of the guide claw 31 and the guide groove of the second guide claw 32 partially penetrate into the hole of the head of the cable tie and this part is also penetrated into the through hole (not shown) located in the locking position 21; then the cylinder 6 is started to push the push rod 5 to move forward, thereby driving the first guide claw 31 to hook inward, so that the tail of the cable tie moves upward, and during the movement of the push rod 5, the through hole 51 is just aligned with the through hole in the locking position 21, so that the first guide claw 31 can push the tail of the cable tie to pass through the through hole 51 smoothly during the movement; then when the cylinder 6 is reset, it drives the push rod 5 to move backward, so that the tail of the cable tie can be cut off.

[0035] like Figure 2 and Figure 3As shown, the cable tie machine also includes a tensioning mechanism; the tensioning mechanism includes a strap driving wheel 11 located above the perforation 51 and at least one strap passive wheel 12 cooperating with the strap driving wheel 11, and a motor 13 for driving the strap driving wheel 11 and the strap passive wheel 12. Preferably, two strap passive wheels 12 are provided; the strap driving wheel 11 and the strap passive wheel 12 are both arranged on the frame 2. Preferably, gears that are coaxially fixedly connected to the strap driving wheel 11 and the strap passive wheel 12 and mesh with each other are also provided outside the strap driving wheel 11 and the strap passive wheel 12, and the motor 13 transmits force to the gears to drive the strap driving wheel 11 and the strap passive wheel 12 to move. Since the above part is the prior art, it will not be described in detail here. When the tail of the cable tie passes through the through hole 51 upward, it enters the gap between the active pulley 11 and the passive pulley 12 and is tightened by the active pulley 11 and the passive pulley 12, and has a tendency to move upward continuously until the active pulley 11 and the passive pulley 12 can no longer pull the cable tie. In this way, the cable tie completes the bundling of the items, and then the tail of the cable tie can be cut off with the cutter 7.

[0036] Preferably, Figure 5 and Figure 6As shown, the tensioning mechanism includes a cable tie machine torque adjustable device 14, which is arranged on the frame 2; the cable tie machine torque adjustable device 14 includes a base 141, a rotating shaft 142, a pressing piece 143, an elastic piece 144 and a positioning piece 145; the base 141 is rotatably arranged on the frame 2 and driven by the motor 13, a slot 146 is arranged on the base 141, and at least one embedding position 147 is arranged on the side wall of the slot 146; the rotating shaft 142 is transmission-connected to the pull belt driving wheel 11 and one end of the rotating shaft 142 is inserted into the slot 146; the elastic piece 144 and the pressing piece 143 are sequentially arranged in the rotating shaft 142 along the length direction of the rotating shaft 142, and one end of the pressing piece 143 is connected to one end of the elastic piece 144; the positioning piece 145 At least one positioning member 145 is provided and is clamped on the side wall of the rotating shaft 142. One end of the positioning member 145 extends outside the rotating shaft 142 and the end cooperates with the embedding position 147. The end face of the positioning member 145 that extends out of the rotating shaft 142 (i.e., the outer end) is an arc-shaped surface. The other end (i.e., the inner end) of the positioning member 145 is movably connected to the other end of the pressing member 143. In order to facilitate the cooperation between the positioning member 145 and the embedding position 147, the side wall of the embedding position 147 is also an arc-shaped surface. A screw rod 149 is threadedly connected to the other end of the rotating shaft 142. One end of the screw rod 149 is connected to the other end of the elastic member 144. By setting the screw rod 149, the tension of the cable tie can be set. The positioning member 145 is contracted inwardly to make the pressing member 143 move upward and the elastic member 144 contract. Preferably, the elastic member 144 is a spring or elastic rubber. In this embodiment, the elastic member 144 is a spring; and the pressing member 143 and the positioning member 145 are both steel balls. A clamping hole with a diameter smaller than that of the positioning member 145 is provided on the side wall of the rotating shaft 142 so that the positioning member 145 will not fall out of the rotating shaft 2. Preferably, in this embodiment, there are four positioning members 145 and four embedding positions 147; the four positioning members 145 are evenly distributed on the side wall of the rotating shaft 142, so that the pressure member 143 is more evenly stressed and moves more stably; the four embedding positions 147 are evenly distributed on the side wall of the slot 146; but those skilled in the art should know that the number of the positioning members 145 and the embedding positions 147 is not limited to four, and the number can also be appropriately increased or decreased. A transmission gear 148 is fixed on the outer wall of the rotating shaft 142, and the rotating shaft 142 is connected to the belt driving wheel 11 through the transmission gear 148. The specific setting method is that the transmission gear 148 is transmitted to the gear that is coaxially fixed to the belt driving wheel 11. In order to better transmit the power between the motor 13, the adjustable torque device 14 of the cable tie machine and the belt driving wheel 11, a gear assembly can be arranged between the motor 13 and the base 141, and a gear assembly is also arranged between the transmission gear 148 and the gear that is coaxially fixed to the belt driving wheel 11. In this way, the transmission can be made more reasonable and more stable. The gear assembly includes planetary gears, internal and external gears, etc., which are not described in detail here.The operating principle of the torque adjustable device 14 of the cable tie machine is as follows: the base 141 is rotated by the drive of the motor 13, and the positioning member 145 is embedded in the embedding position 147, so that the base 141 drives the rotating shaft 142 to rotate synchronously when rotating, and when the rotating shaft 142 rotates, the force is transmitted to the pulley driving wheel 11 and the pulley driven wheel 12 through the transmission gear 148, so that the pulley driving wheel 11 and the pulley driven wheel 12 can pull the tail of the cable tie upward to tie the cable tie to the object. When the tension torque of the cable tie reaches or exceeds the preset torque of the elastic member 144, the rotating shaft 142 stops rotating, and the positioning member 145 is forced to shrink, thereby driving the pressing member 143 to move toward the elastic member 144, so that the elastic member 144 also shrinks. At this time, the pressure member 143 is driven by the pressure member 143 to move toward the elastic member 144, so that the elastic member 144 also shrinks. As the positioning member 145 shrinks inward, the rotating shaft 142 will not be damaged even if the base 141 continues to rotate, and the draw belt active wheel 11 and the draw belt passive wheel 12 are prevented from breaking the cable tie. During the rotation of the base 141, when the embedded position 147 rotates to the position of the positioning member 145, the positioning member 145 will be extended by the elastic force of the elastic member 144, and as the base 141 continues to rotate, the positioning member 145 will shrink inward again, and this reciprocating process will continue to cycle; when the cable tie between the draw belt active wheel 11 and the draw belt passive wheel 12 is removed, the draw belt active wheel 11, the draw belt passive wheel 12 and the rotating shaft 142 will no longer be subject to resistance, so that the rotating shaft 142 and the draw belt active wheel 11 and the draw belt passive wheel 12 continue to rotate with the base 141.

[0037] Of course, a waste channel and an air pipe are also provided in the frame 2, but these are all prior arts and will not be described in detail here.

[0038] The working principle of the present invention is described below to facilitate understanding of the present invention:

[0039] First, press the trigger 8 to close the first guide claw 31 and the second guide claw 32, the sensing rod 9 moves upward and is sensed by the sensor 10, the motor 13 starts, and the cable tie driving wheel 11 and the cable tie passive wheel 12 are driven to move through the cable tie machine torque adjustable device 14; the feeding mechanism feeds and transports the cable tie to the guide groove of the cable tie guide rail 4, and then successively penetrates into the guide groove of the first guide claw 31 and the guide groove of the second guide claw 32, at this time, a part of the tail of the cable tie penetrates into the hole of the head of the cable tie; then the cylinder 6 starts, pushing the push rod 5 forward, and at the same time driving the first guide claw 31 to hook inward, so that the tail of the cable tie passes through the push rod 5. The through hole 51 of the rod 5 is tightened by the active pulley 11 and the passive pulley 12; when the cable tie can no longer be pulled and the active pulley 11 and the passive pulley 12 are forced to stop, the rotating shaft 142 also stops synchronously, and the positioning member 145 is forced to perform reciprocating motion of contraction and extension on the rotating shaft 142 due to the continued rotation of the base 141; finally, the cylinder 6 is reset, so that the push rod 5 moves backward synchronously, and when the push rod 5 moves, the cutter 7 cuts off the tail of the cable tie in the through hole 51, and after the tail of the cable tie is cut off, the air pipe unloads the waste, thus completing the process of bundling the items with a cable tie, and then the motor continues to drive the tensioning mechanism to operate.

[0040] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
