Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a cable tie binding machine tensioning mechanism. Background Technology

[0002] The main function of a cable tie binding machine is to ensure that products remain secure and neat during transportation and storage, while maintaining their aesthetic appeal. It works by wrapping products or packages with cable ties and connecting the ends through a tightening process, which may involve heat melting or the use of materials such as buckles. The tension mechanism of the cable tie binding machine is the core component that enables the tightening and securing of the cable ties, and its design must comprehensively consider the mechanical structure, control method, and performance parameters. The following are key technical points: The tension mechanism typically includes components such as ratchet teeth, levers, and elastic elements, and tightens the cable ties through manual operation or pneumatic drive. For example, a handle hinged within the machine housing is linked to the ratchet teeth via a lever, allowing for the application of tension and replacing manual operation to ensure a secure binding. Some models employ pneumatic tensioning devices (such as pneumatic strapping tensioners), utilizing pneumatic power to improve tightening efficiency, suitable for high-intensity or high-frequency operation scenarios. The advanced tension mechanism is equipped with a fully computerized control system, supports multilingual operating interfaces, and achieves precise control via wireless remote control or LCD screen; the automated model integrates sensors and PLC control modules, which can monitor tension parameters in real time to ensure that the tensioning process meets the preset accuracy.

[0003] In existing technologies, cable tie binding machines fasten cable ties to objects through a series of mechanical actions. During the conveying process of the cable tie, when the ratchet and conveyor belt pull the cable tie out, the cable tie is prone to deviate during the high-speed transmission process, which affects the area of ​​the cable tie being wrapped and causes errors, thereby reducing the wrapping accuracy of the cable tie. To address this, a cable tie binding machine tension mechanism is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment of a cable tie binding machine tension mechanism includes a mounting base 1, a main motor 2 externally mounted on the mounting base 1, a rotating rod 3 fixedly connected to the output end of the main motor 2, a ratchet 4 on the outer wall of the rotating rod 3, a conveyor belt 5 on the outer wall of the rotating rod 3, a mounting groove 6 inside the rotating rod 3, a protective component inside the mounting groove 6, a limiting component inside the mounting base 1, the protective component including a mounting screw 7 inside the mounting groove 6, a vertical plate 8 at one end of the mounting screw 7, a slot 9 inside the vertical plate 8, a limiting groove 10 on the inner side wall of the slot 9, a limiting rod 11 on the inner bottom wall of the limiting groove 10, a connecting block 12 inside the limiting groove 10, a push plate 13 externally mounted on the connecting block 12, a limiting arc plate 14 on one side of the push plate 13, a threaded post 15 inside the vertical plate 8, and a mounting plate 16 at the top of the threaded post 15.

[0023] like Figure 1-4As shown, the tension mechanism in this utility model is similar to existing tension mechanisms. The main improvement of this utility model is that it can improve the conveying stability during the cable tie conveying process. While cooperating with the protective components, the spacing of the protective components can be adjusted according to different specifications of cable ties, thereby improving the safety of the cable tie conveying process. The main motor 2 in this utility model is existing technology. When using this tension mechanism, by starting the main motor 2, the main motor 2 drives the ratchet 4 to rotate through the rotating rod 3. The rotating ratchet 4 drives the conveyor belt 5 to rotate through the rotating rod 3. The rotating vertical plate 8 drives the mounting screw 7 to insert into the mounting groove 6, causing the rotating mounting plate 16 to rotate. The rotating mounting plate 16 drives the threaded column 15 to rotate inside the vertical plate 8. Moreover, the rotating threaded column 15 rotates and squeezes the push plate 13 to slide. The sliding push plate 13 drives the connecting block 12 to slide outside the limiting rod 11. Thus, the sliding push plate 13 drives the limiting arc plate 14 to limit the cable ties outside the conveyor belt 5.

A lever 18 is disposed on the outer wall of the compression plate 17, and a connecting plate 19 is disposed on the outer wall of the compression plate 17. A slot 20 is opened on the outer wall of the connecting plate 19. A locking rod 21 is disposed inside the mounting base 1. The cable tie is fed by rotating a ratchet 4. At the same time, the rotating ratchet 4 drives the lever 18 to rotate through the compression plate 17. If the ratchet 4 reverses, the lever 18 is inserted into the ratchet 4 to block it. Then the locking rod 21 is inserted into the vertical plate 8, so that the locking rod 21 and the slot 20 are engaged and fixed to prevent reverse rotation.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model.
