Description

Technical Field

[0002] A pneumatic cable tie machine is an automated or semi-automatic device that works on the principle of pneumatics. It is mainly used to quickly and accurately tie cable ties to objects to achieve the purpose of fixing, binding or sealing.

[0003] A 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 ties. The transmission device generally includes the output shaft of the pneumatic device, a reduction gear, and a cable tie material supply device, converting the high-speed rotational power into a low-speed, high-torque force to facilitate tightening the cable ties.

[0004] As shown in patent CN207141476U, in the case of a cable tie feeding device, several individual cable ties are placed on a vibratory feeder, which feeds them one by one.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0059] As Figures 1 to 10 As shown in the figure, the present application provides a continuous feeding device for a roll of strapping 1 for conveying strapping 1, which includes a head with a locking hole and a tail with a locking tooth, and the tail is in the form of a belt. The strapping 1 of the present embodiment is longer than the ordinary strapping 1, and the strapping 1 of the present embodiment is more than 20 cm, can reach 30 cm, or even 40 cm, and is mainly used to bundle some large wire harnesses or articles. Adjacent said strapping 1 is connected together by a connecting strip, said connecting strip includes an upper connecting strip 11 and a lower connecting strip 12, which are respectively arranged at positions close to the head and tail of said strapping 1. The upper connecting strip 11 and the lower connecting strip 12 are respectively formed with an empty position A on both sides. A plurality of said strapping 1 are connected together and in the form of a roll.

[0060] In order to better describe the continuous feeding device of the roll binding tape 1, the direction of the first direction is X, the direction of the second direction is Y, and the direction of the third direction is Z in the embodiment of the application, wherein the first direction, the second direction and the third direction are perpendicular to each other, and correspond to three perpendicular axial directions respectively, and the continuous feeding device of the roll binding tape 1 comprises:

[0061] The box 2 comprises an inner side and an outer side, and the outer side of the box 2 is designed to have a space position, at which the outer side of the box 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, the reel 21 is provided with a winding disc 22, the winding disc 22 is detachably connected with the reel 21, the roll of the binding tape 1 is wound on the winding disc 22, and the box 2 is further provided with an inlet 23 and an outlet 24, the winding disc 22 rotates, and the binding tape 1 on the winding disc 22 is fed towards the inlet 23, and it should be noted that the binding tape 1 must have an upper connecting strip 11 and a lower connecting strip 12, and are arranged at positions close to the head and tail of the binding tape 1 respectively, because the length of the binding tape 1 is relatively long, if there is only a single connecting strip, the head or tail of the binding tape 1 or both will fall on one side or both sides during rotation, and the binding tape 1 will be wound together or stuck with other parts during rotation or movement;

[0062] The cutting mechanism 4 is arranged in the box 2 and comprises a first feeding assembly 41, a cutting assembly 42, a second feeding assembly 43 and a pneumatic conveying assembly 44, in order to make the roll of the binding tape 1 more smoothly pass to the cutting mechanism 4, the outer side of the box 2 is provided with a guide shaft 3 which rotates below the inlet 23 and close to the inlet 23.

[0063] The first feeding assembly 41 comprises a first feeding channel 411 extending in the first direction and a first driving part 412, the guide shaft 3 guides the binding tape 1 into the first feeding channel 411, the first feeding channel 411 is communicated with the inlet 23, and the first driving part 412 is used to drive the binding tape 1 to move in the first direction on the feeding channel;

[0066] The pneumatic conveying assembly 44 is communicated with the outlet 24.

[0067] This invention provides a continuous feeding device for coiled cable ties 1. For excessively long cable ties 1, the cable ties 1 are connected together by an upper connecting strip 11 and a lower connecting strip 12 and wound onto a reel 22. The cable ties 1 are fed to the cutting mechanism 4 by the rotation of the reel 22 and the shaft 21. The first driving unit 412 drives the cable ties 1 to move along a first direction on the first conveying channel of the first feeding assembly 41. When the cable ties 1 move to the end of the first conveying channel, the cutting assembly 42 cuts off the upper connecting strip 11 and the lower connecting strip 12 connecting the cable ties 1 one by one, so that each cable tie 1 is independent. Then, the second feeding assembly 43 conveys the individual cable ties 1 to the pneumatic conveying assembly 44. The pneumatic conveying assembly 44 finally conveys the cable tie 1 to the cable tie gun, which performs the cable tie 1 cutting, realizing stable and continuous cutting and feeding, and improving the efficiency of the cable ties 1.

The second clearance openings 4141 are located above the first clearance openings 4131.

[0069] The cutting assembly 42 is provided in two sets, respectively applied to cutting off the upper connecting strip 11 and the lower connecting strip 12. The cutting assembly 42 includes a cutting fixing plate 421, which extends in a third direction. A first slide rail 422 extending in a third direction is provided on the cutting fixing plate 421. A first slider 423 is slidably provided on the slide rail 422. A first cylinder 424 is also provided on the cutting fixing plate 421. The output end of the first cylinder 424 is connected to a first adapter plate 425.

[0071] Specifically, when the cable tie 1 is conveyed to the position of the first avoiding through hole 4131, the upper connecting strip 11 and the lower connecting strip 12 correspond to above the two first avoiding through holes 4131 respectively, the first air cylinder 424 drives the cutter part 426 to move upward along the third direction, the positioning plate 4263 clamps and positions the avoiding position A on both sides of the upper connecting strip 11 and the lower connecting strip 12 in the process of upward movement of the cutter part 426, and the cutting knife 4264 cuts at the same time, the positioning plate 4263 is clamped in the avoiding position A when moving upward, the two positioning plates 4263 clamp the connecting strip in the middle, and the positioning plate 4263 is clamped into the second avoiding through hole 4141, the two sides of the connecting strip are limited, the connecting strip cannot move because of the limitation of the positioning plate 4263 when the cutting knife 4264 cuts, so that the cutting knife 4264 can accurately cut off the connecting strip and will not damage the cable tie 1 itself, the upper connecting strip 11 and the lower connecting strip 12 are cut off, so that the upper connecting strip 11, the lower connecting strip 12 and the cable tie 1 on both sides are separated, and the upper connecting strip 11 and the lower connecting strip 12 fall from the hollow structure of the cutter body 4262.
