[0051] As Figure 1 and Figure 2As shown, the present application provides a cable tie binding device, which comprises a support rod assembly 1, a cable tie fixing assembly 2, a cable tie feeding assembly 3, a cable tie tensioning assembly 4 and a cable tie cutting assembly 5. The support rod assembly 1 comprises a vertical rod part 11 and a horizontal rod part 12, and the horizontal rod part 12 is adjustably arranged on the vertical rod part 11. The cable tie fixing assembly 2 is arranged on the vertical rod part 11 and is used to detachably fix the head of the cable tie 100. In this embodiment, the head of the cable tie 100 is detachably fixed by the cable tie fixing assembly 2, which facilitates the separation of the cable tie 100 from the cable tie binding device after the binding of the cable tie 100, avoids affecting the binding operation of the next cable tie 100, realizes the repeated use of the cable tie binding device and reduces the binding cost. Specifically, a vertical installation through slot is formed on the vertical rod part 11, and an operator uses a bolt to pass through the vertical installation through slot and is screwed on the horizontal rod part 12. The head of the bolt abuts against the vertical rod part 11, so as to fix the horizontal rod part 12 on the vertical rod part 11. When height adjustment is needed, the operator loosens the bolt and adjusts the height of the horizontal rod part 12 on the vertical rod part 11. After the adjustment is completed, the bolt is tightened again, and the height adjustment of the horizontal rod part 12 is completed.

[0052] The cable tie feeding assembly 3 comprises a mounting rod 31, a first motor 32 and a pushing head 33, the first motor 32 and the pushing head 33 are arranged on the mounting rod 31, the mounting rod 31 is adjustably arranged on the horizontal rod part 12, the middle section of the cable tie 100 elastically abuts on the horizontal rod part 12 and the mounting rod 31, and the tail of the cable tie 100 is detachably arranged on the pushing head 33, so that the middle section of the cable tie 100 semi-surrounds the object to be bound. The first motor 32 can drive the pushing head 33 to approach the head of the cable tie 100 in the first direction, so as to drive the tail of the cable tie 100 to pass through the locking hole of the head of the cable tie 100 in one direction. In this embodiment, the tail of the cable tie 100 abuts on the pushing head 33, the pushing head 33 guides and pushes the cable tie 100, and the tail of the cable tie 100 is driven to pass through the locking hole of the head in one direction by the pushing head 33 approaching the head of the cable tie 100, so that the object to be bound can be bound without the operator aligning and threading the cable tie 100, which is simple, time-saving and labor-saving, and improves the binding efficiency. Specifically, a horizontal mounting through slot is formed in the horizontal rod part 12, the operator passes the bolt through the horizontal mounting through slot and screws it on the mounting rod 31, and the head of the bolt abuts on the horizontal rod part 12, so as to fix the mounting rod 31 on the horizontal rod part 12. When the horizontal position of the mounting rod 31 needs to be adjusted, the operator loosens the bolt and adjusts the horizontal position of the mounting rod 31 on the horizontal rod part 12, and then tightens the bolt again after the adjustment is completed, so as to complete the position adjustment of the mounting rod 31. Specifically, the horizontal rod part 12 is perpendicularly connected with the vertical rod part 11, and the mounting rod 31 is perpendicularly connected with the horizontal rod part 12, so as to form a rectangular semi-surrounding space with adjustable size between the three, which facilitates the operation of the cable tie feeding assembly 3 in a limited space and prevents external foreign matters from interfering with the cable tie 100.

[0053] The cable tie tensioning assembly 4 is arranged on the vertical rod part 11, and comprises a second motor 41 and a tensioning wheel set 42 arranged on the output end of the second motor 41. The tensioning wheel set 42 is used for applying force to the tail of the cable tie 100, so as to tightly bind the middle section of the cable tie 100 to the object to be bound. In this embodiment, the tensioning wheel set 42 applies force to the tail of the cable tie 100, so that the middle section of the cable tie 100 abuts on the object to be bound and is tightly bound, which improves the firmness of the binding.

[0054] The cable cutting assembly 5 comprises an electric push rod 51 and a blade 52 arranged on the electric push rod 51, the electric push rod 51 is arranged on the vertical rod part 11, and the blade 52 of the electric push rod 51 is used to cut the middle section of the cable 100 passing through the locking hole. In the embodiment, the middle section of the cable 100 passing through the locking hole is cut by the blade 52, and the excess part of the cable 100 is smoothly cut off, thereby reducing the occupied space of the cable 100; since the horizontal rod part 12 is adjustably arranged on the vertical rod part 11, and the mounting rod 31 is adjustably arranged on the horizontal rod part 12, the space between the vertical rod part 11, the horizontal rod part 12 and the mounting rod 31 can accommodate the cable 100, thereby being capable of placing cables 100 of different specifications and sizes, and improving the application range of the cable binding device; in addition, since the push head 33 is driven to move by the first motor 32, the tensioning wheel set 42 is driven to rotate by the second motor 41, and the blade 52 is driven to cut by the electric push rod 51, a series of threading, tensioning and cutting steps can be completed without manual operation of the operator, thereby saving time and effort, being convenient and fast.

In this embodiment, the driving wheel 421 and the driven wheel 422 are oppositely arranged and have a gap therebetween, and the width of the gap is slightly smaller than the thickness of the cable tie 100, so that the cable tie 100 can pass through the gap and be compressed by the driving wheel 421 and the driven wheel 422, thereby pulling the cable tie 100.

[0061] Specifically, the driving wheel 421 is a knurled wheel, and the driven wheel 422 is a rubber wheel. In this embodiment, the knurled wheel is a rolling wheel with knurls on the rolling surface, and the knurls can greatly enhance the friction of the rolling wheel surface. The rubber wheel has a certain elasticity and can cooperate with the driving wheel 421 and deform to some extent, thereby effectively tightening the cable tie 100.

[0062] Further, as shown in Figure 7 The cable tie fixing assembly 2 includes a limiting frame 21 and a second elastic clamping piece 22. The limiting frame 21 is arranged to form a limiting groove for accommodating the head of the cable tie 100. The second elastic clamping piece 22 is arranged on the limiting frame 21 and abuts against the head of the cable tie 100. Specifically, like the first elastic clamping piece 332, the second elastic clamping piece 22 is an elastic metal sheet and can elastically abut against both sides of the head of the cable tie 100 to fix the head of the cable tie 100. Since the second elastic clamping piece 22 is arranged, the limiting groove can accommodate and fix cable ties 100 of different sizes, thereby improving the applicability of the cable tie binding device.

[0063] Further, as shown in Figure 7 and Figure 8 , one end of the blade 52 is rotatably arranged on the vertical rod part 11, and the other end of the blade 52 is rotatably connected with the output end of the electric push rod 51. The electric push rod 51 can drive the blade 52 to rotate to cut the middle section of the cable tie. Specifically, the cable tie binding device further comprises a passing partition plate arranged on the vertical rod part 11, and the limiting frame 21 is fixed on the passing partition plate. The passing partition plate is provided with a passing hole located in the limiting groove. The locking hole of the head of the cable tie 100 is aligned with the passing hole, and the tail of the cable tie 100 passes through the locking hole and then passes through the passing partition plate through the passing hole. The blade 52 is arranged on the other side of the passing partition plate opposite to the limiting frame 21 and below the passing hole, and is used for cutting the excess cable tie 100. One end of the blade 52 is rotatably arranged on the passing partition plate through a pin shaft, and the other end of the blade 52 is connected with the output end of the electric push rod 51, thereby forming a guillotine structure. When the electric push rod 51 is turned on, one end of the blade 52 will rotate upward, thereby cutting off the cable tie 100. Compared with the ordinary straight-up and straight-down cutting tool, the blade 52 and the passing partition plate form a labor-saving lever structure, and the cutting is easier and more convenient.

[0064] Further, as shown in Figure 1 and Figure 2 , the cable tie binding device further comprises a holding rod 6, one end of which is arranged at the bottom of the vertical rod part 11 in an angle-adjustable manner. Specifically, the holding rod 6 is mainly used for hand holding, increasing the operation length, so that the operator can stand on the ground to bind objects at a high place. The holding rod 6 is connected with the vertical rod part 11 through a pin shaft, and the holding rod 6 and the vertical rod part 11 can rotate relative to each other. The operator can adjust the angle between the holding rod 6 and the vertical rod part 11 by rotating the pin shaft, so as to adjust the angle and position of binding. When binding objects at a low or near place, the operator can also remove the holding rod 6 from the vertical rod part 11 by loosening the pin shaft, thereby improving the flexibility and practicability of the cable tie binding device. In addition, the cable tie binding device further comprises a remote controller, which can remotely control the start and stop of the first motor 32, the second motor 41 and the electric push rod 51. The remote controller can be arranged on the holding rod 6, which is convenient for the operator to operate. The remote controller is provided with an indicator light, which can indicate the working state of the cable tie binding device. The remote controller is also provided with a current monitoring display panel of the second motor 41, which can display the load current of the second motor 41. The operator can compare the working current of the second motor 41 with the normal current to determine whether the cable tie 100 is tight, so as to avoid damaging the object to be bound due to over-tightening of the cable tie 100.

[0065] The embodiment also provides a cable tie binding method using the cable tie binding device described above, which comprises the following steps:

[0066] S1, the head of the cable tie 100 is placed in the cable tie fixing assembly 2, the tail of the cable tie 100 is arranged on the pushing head 33, and the middle section of the cable tie 100 is elastically pressed on the cross rod part 12 and the mounting rod 31, so that the cable tie 100 forms a half-enclosing structure. Specifically, the operator places the head and tail of the cable tie 100 on the cable tie fixing assembly 2 and the pushing head 33 respectively, so as to complete the installation preparation work before binding.

[0067] S2, the cable tie binding device is lifted and aligned with the object to be bound, and the middle section of the cable tie 100 is located on one side of the object to be bound and half-encloses the object to be bound. Specifically, the operator adjusts the cross rod part 12 and the mounting rod 31 to the appropriate position according to the position of the object to be bound, and if the object to be bound is located at a high position, a holding rod 6 can also be installed at the bottom of the vertical rod part 11, so as to increase the operation height.

[0068] S3, the first motor 32 and the second motor 41 are started, the pushing head 33 drives the tail of the cable tie 100 to pass through the locking hole in one direction, and the tensioning wheel set 42 applies force to the tail of the cable tie 100, so as to tighten the object to be bound. Specifically, the operator starts the first motor 32 and the second motor 41 through the remote controller, so that the tail of the cable tie 100 passes through the locking hole, and the object to be bound is tightened by tightening the cable tie 100 through the tensioning wheel set 42. While the tensioning wheel set 42 pulls the cable tie 100, the operator controls the first motor 32 to rotate in the opposite direction, so that the pushing head 33 returns to the retracted position.

[0069] S4, the electric push rod 51 is turned on, and the electric push rod 51 drives the blade 52 to cut the middle section of the cable tie 100 passing through the locking hole. Specifically, after the object to be bound is tightened, the operator uses the remote controller to turn off the first motor 32 and start the electric push rod 51 to drive the blade 52 to cut the middle section of the cable tie 100.

[0070] S5, the head of the cable tie 100 is detached from the cable tie fixing assembly 2. Specifically, after the cable tie 100 is cut, the operator gently pulls the cable tie binding device in the first direction, so that the head of the cable tie 100 falls off from the cable tie fixing assembly 2; thus, the binding of the cable tie 100 is completed.
