[0002] Pneumatic cable tie machine is an automated or semi-automated device that works on the pneumatic principle. It is mainly used to quickly and accurately tie cable ties around objects to achieve the purpose of fixing, bundling or packaging.

[0003] The pneumatic cable tie machine is powered by a pneumatic device. Its basic components include a housing, a pneumatic device, a transmission device, a cable tie material supply device, and a control system. The pneumatic device drives the transmission device to tighten and fix the cable tie. The transmission device generally includes the output shaft of the pneumatic device, a speed reduction mechanism, and a cable tie material supply device, which converts high-speed rotating power into low-speed high-torque power to tighten the cable tie.

[0004] As part of the cable tie material supply device, as shown in patent CN207141476U, a number of individual cable ties are placed on a vibrating plate, and the vibrating plate is used to feed the cable ties one by one. In this case, it is only applicable to cable ties shorter than 10 cm.

[0059] like Figures 1 to 10 As shown, the present invention provides a continuous feeding device for a rolled cable tie 1, which is used to convey the cable tie 1. The cable tie 1 includes a head with a locking hole and a tail with locking teeth, and the tail is in a belt shape. The cable tie 1 in the embodiment of the present invention is longer than the ordinary cable tie 1. The cable tie 1 in the embodiment of the present invention is longer than 20 cm, and can reach 30 cm, or even 40 cm. It is mainly used to bundle some large wire harnesses or objects. Adjacent cable ties 1 are connected together by connecting strips, and the connecting strips include an upper connecting strip 11 and a lower connecting strip 12, which are respectively arranged at positions close to the head and tail of the cable tie 1, and avoidance positions A are formed on both sides of the upper connecting strip 11 and the lower connecting strip 12, respectively. A plurality of the cable ties 1 are connected together and are in a rolled package.

[0060] In order to better describe the continuous feeding device of the rolled cable tie 1, in the embodiment of the present invention, the first direction is X, the second direction is Y, and the third direction is Z, wherein the first direction, the second direction and the third direction are perpendicular to each other and correspond to three perpendicular axes respectively. The continuous feeding device of the rolled cable tie 1 includes:

[0061] The box body 2 includes an inner side and an outer side. A space position is designed on the outer side of the box body 2. At this space position, the outer side of the box body 2 rotates the reel 21. The reel 21 can be driven to rotate without power, or can be driven to rotate by a motor or the like.

It should be noted that the cable tie 1 must have an upper connecting strip 11 and a lower connecting strip 12, which are respectively arranged near the head and tail of the cable tie 1. Because the cable tie 1 itself is relatively long, if there are only a single connecting strip, the head or tail or both of the cable tie 1 will fall off on one side or both sides during the rotation process, and the cable tie 1 will be coiled together or stuck with other parts during the rotation or movement process.

[0062] The tape cutting mechanism 4 is arranged in the box body 2, and includes a first feeding component 41, a cutting component 42, a second feeding component 43 and a pneumatic conveying component 44; in order to make the rolled cable tie 1 transition to the tape cutting mechanism 4 more smoothly, the outer side of the box body 2 is close to the position of the feed port 23, and a guide shaft 3 is rotatably arranged below the feed port 23.

[0063] The first feeding assembly 41 includes a first feeding channel 411 extending along a first direction and a first driving part 412, the guide shaft 3 guides the cable tie 1 into the first feeding channel 411, the first feeding channel 411 is connected to the feed port 23, and the first driving part 412 is used to drive the cable tie 1 to move along the first direction on the feeding channel;

For a cable tie 1 that is too long, the cable tie 1 is connected together through an upper connecting strip 11 and a lower connecting strip 12, and is wound on a reel 22. The cable tie 1 is fed to a cutting mechanism 4 through the rotation of the reel 22 and the reel 21. The first driving unit 412 drives the cable tie 1 to move along a first conveying channel of a first feeding component 41 in a first direction. When the cable tie 1 moves to the end of the first conveying channel, the cutting component 42 cuts off the upper connecting strip 11 and the lower connecting strip 12 connected to the cable tie 1 one by one, so that the cable ties 1 are single and independent one by one. Then, the single cable tie 1 is fed to a pneumatic conveying component 44 through a second feeding component 43. The pneumatic conveying component 44 is finally fed to a cable tie gun 1. The cable tie gun 1 performs stable and continuous cutting and feeding of the cable tie 1, thereby improving the efficiency of the cable tie 1.
