[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0034] Example

[0035] Reference Figure 1 、 2 , 3 and 8, in one embodiment of the present utility model, an automatic cable tie module is disclosed, which is used on a cable tie machine. The automatic cable tie module includes:

[0036] The driving mechanism includes a brushless motor 5, a first rolling element 54, and a second rolling element 53. The first rolling element 54 and the second rolling element 53 are meshed and connected. The first rolling element 54 and the second rolling element 53 are arranged opposite each other with a rolling gap 56 between them. The brushless motor 5 drives the first rolling element 54 to rotate, and the first rolling element 54 then drives the second rolling element 53 to roll synchronously. When the cable tie 7 is located in the rolling gap 56, the cable tie 7 moves along a third direction Z to achieve tightening under the friction force of the first rolling element 54 and the second rolling element 53. The third direction Z is the vertical direction.

[0037] The pressure sensor 3 is electrically connected to the brushless motor 5 through the PLC. The housing of the pressure sensor 3 is provided with a first guide hole 34 facing the rolling gap 56. Before tying, the head 71 of the cable tie 7 is manually passed around the object to be tied and then passes through the limiting hole 73 of the cable tie buckle 72, the first guide hole 34 and the rolling gap 56. In this embodiment, the objects to be tied are such as corrugated pipes, wire harnesses, etc., as shown in FIG. Figure 8 As shown, the cable tie 7 is made of plastic, nylon, or metal with a certain strength, and includes a buckle 72, a strap body 74, and a strap head 71. During the binding process, the pressure sensor 3 detects the tension of the cable tie 7 located in the first guide hole 34, so that the brushless motor 5 starts or stops according to the tension to control the tightness of the cable tie 7. The tightness of the cable tie 7 can also be customized by setting the pressure value of the pressure sensor 3 to meet different packaging requirements.

[0038] In one embodiment of the present invention, referring to Figure 1 and 7 As shown, it also includes a support base 4, and the pressure sensor 3 can be detachably connected to the support base 4. The support base 4 is provided with a second guide hole 41, and the second guide hole 41 is located between the first guide hole 34 and the rolling gap 56. The second guide hole 41, the first guide hole 34 and the rolling gap 56 are located in a straight line along the vertical direction, and are used to accurately guide the cable tie head 71 after passing through the first guide hole 34 into the rolling gap 56.

[0039] In one embodiment of the present invention, referring to Figure 6 As shown, the housing 3 of the pressure sensor 3 is provided with a first avoidance hole 32 and a second avoidance hole 33 on both sides of the first guide hole 34 along the first direction X. Regardless of whether the cable tie 7 is placed on the pressure sensor housing 3 in the forward or reverse direction, the first avoidance hole 32 and the second avoidance hole 33 can avoid the disc-shaped structure of the cable tie buckle 72, so that regardless of whether the cable tie 7 is placed in the forward or reverse direction, it can be placed horizontally on the pressure sensor housing 3.

[0040] In one embodiment of the present invention, referring to Figure 1 and 4 As shown, it also includes a guide tube 9, which is located directly below the rolling gap 56, and the axis of the guide tube 9 is coaxially arranged with the first guide hole 34 and the second guide hole 41. When the head 71 of the cable tie 7 passes through the rolling gap 56, it directly enters the guide tube 9 and moves downward along the guide tube 9 to prevent the head 71 of the cable tie 7 from being entangled in the driving mechanism and causing the driving mechanism to stop unexpectedly.

[0041] In one embodiment of the present invention, referring to Figure 1 and5 As shown, it also includes a cable tie fixing base 2 that can be detachably connected to the pressure sensor 3. The cable tie fixing base 2 is provided with a limit groove. Before binding, the cable tie buckle 72 is manually placed vertically downward into the limit groove to limit the cable tie buckle 72 in the first direction X and the second direction Y. The first direction X and the second direction Y are both horizontal directions.

When the pressure sensor 3 detects that the tightness of the cable tie 7 reaches a set value, the motor 5 stops working. At this time, the cylinder 6 drives the cutter 61 to extend between the first guide hole 34 and the second guide hole 41 along the first direction X to cut the cable tie 7. In other embodiments, a solenoid valve can be provided, and the pressure sensor 3 controls the opening and closing of the cylinder 6 through the solenoid valve, so that the motor 5 stops tightening the cable tie 7 and the cutter 61 can automatically extend to cut the cable tie 7, thereby improving the degree of automation.

The slider 8 is slidably connected to the housing 11, and the cylinder 81 is configured to be able to abut against the conveyor belt 52 by manually sliding the slider 8.

[0050] In one embodiment of the present invention, referring to Figure 4 As shown, in order to ensure that the first rolling body 54 and the second rolling body 53 always press the belt body 74 so that the rolling gap 56 adaptively matches the cable ties 7 of different thicknesses, a spring 55 is also included inside the shell, one end of the spring 55 is connected to the housing 11, and the other end abuts the rotating shaft of the second rolling body 53, one end of the rotating shaft is slidably connected to the housing 11, and the spring 55 always has a tendency to push the second rolling body 53 close to the first rolling body 54.
