[0001] This utility model relates to the field of cable tie processing equipment, specifically to a cable tie cutting mechanism and a cable tie cutting and processing system. Background Technology

[0002] Cable ties, also known as wire ties, cable bundles, or locking straps, are straps used to bundle things together; they are widely used in practice. A cable tie consists of a cable tie head with perforations and a cable tie strip connecting the head. During bundling, the end of the cable tie strip is inserted into the perforation of the cable tie head to secure the bundle. However, in some bundling operations, the original cable ties are too long, and the ends of the cable tie strips are prone to bending in their natural state, which is not conducive to mechanical bundling operations. Therefore, it is necessary to design a device that can mechanically cut and process cable ties. Utility Model Content

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 4 As shown, this embodiment provides a cable tie cutting mechanism, including an opening and closing driver 10, a guide rail 40, a punch portion 20, and a die portion 30. The guide rail 40 is a linear guide rail and is fixedly set. The punch portion 20 and the die portion 30 are slidably mounted on the guide rail 40. In this embodiment, the punch portion 20 is slidably mounted on the guide rail 40 via a first slider 41, and the die portion 30 is slidably mounted on the guide rail 40 via a second slider 42. The opening and closing actuator 10 drives the punch portion 20 and the die portion 30 to move closer or further apart on the guide rail 40. In this embodiment, the opening and closing actuator 10 adopts an opening and closing cylinder in the prior art. The first driving end of the opening and closing cylinder is connected to the punch portion 20, and its second driving end is connected to the die portion 30. The opening and closing action of the first driving end and the second driving end of the opening and closing cylinder drives the punch portion 20 and the die portion 30 to move synchronously.

[0021] The punch portion 20 is provided with a first guide constriction 21 and a cutting punch 22, and the die portion 30 is provided with a second guide constriction 31 and a cutting die 32. The cutting punch 22 is located below the first guide constriction 21, and the cutting die 32 is located below the second guide constriction 31. Both the first guide constriction 21 and the second guide constriction 31 are constriction structures with gradually decreasing opening sizes. In this embodiment, both the first guide constriction 21 and the second guide constriction 31 are trumpet-shaped notches, but they can also be "V"-shaped notches, etc. The first guide constriction 21 and the second guide constriction 31 are corresponding and staggered vertically. That is, when the punch portion 20 and the die portion 30 approach each other, the window area enclosed by the first guide constriction 21 and the second guide constriction 31 gradually shrinks without interference. In this embodiment, the first guide constriction 21 is located above the second guide constriction 31. Of course, in other embodiments, the opposite can also be true. The cutting punch 22 is directly opposite the cutting die 32, meaning they are set at the same height, and is used to cut cable ties.

[0022] Continue to refer to Figure 5 As shown, this embodiment also provides a cable tie cutting system, including a feeding mechanism 100, a transmission mechanism 200, and a cable tie cutting mechanism 300. The output end of the feeding mechanism 100 and the cable tie cutting mechanism 300 are both mounted on the transmission track of the transmission mechanism 200. The feeding mechanism 100 is used to output cable ties. In this embodiment, the feeding mechanism 100 is a vibrating feeder, capable of outputting cable ties one by one at specific positions. The transmission mechanism 200 is located above the cable tie cutting mechanism 300. The transmission mechanism 100 can be a three-axis transmission mechanism, etc., from the prior art. The transmission mechanism 200 has a jaw clamp for holding the cable ties; the jaw clamp is used to grab the cable ties output by the feeding mechanism 100. The cable tie cutting mechanism 300 is the cable tie cutting mechanism described above.

[0023] During the cutting process, the transmission mechanism 200 grips the cable tie output by the feeding mechanism 100, specifically by grasping the cable tie head, while the cable tie strip hangs down naturally during transmission. When the transmission mechanism 200 transmits the cable tie to the corresponding cable tie cutting mechanism 300, that is, when the cable tie strip is located between the punch portion 20 and the die portion 30, the opening and closing driver 10 begins to drive the punch portion 20 and the die portion 30 to move closer together. As the punch portion 20 and the die portion 30 move closer together, the first guide narrowing 21 and the second guide narrowing 31 first merge. As long as the cable tie strip is within the range of the first guide narrowing 21 or the second guide narrowing 31, it can be framed by both guide narrowing 21 and guide narrowing 31. As the punch portion 20 and the die portion 30 continue to move closer, they gradually limit the cable tie strip to the center, thereby positioning the cable tie strip. At this time, the position of the cable tie strip corresponds exactly to the cutting punch 22 and cutting die 32 below. Finally, when the punch portion 20 and the die portion 30 complete their closing, the cable tie strip is cut by the cutting punch 22 and cutting die 32, completing the cutting of the cable tie. This cable tie cutting mechanism has a simple structure and high cutting accuracy.

[0024] Preferably, the end of the cut cable tie is a pointed tip, making it easier to pass through the perforation of the cable tie head during bundling. Therefore, in this embodiment, the cutting punch 22 is a V-shaped protrusion with a V-shaped cross-section, and the end of the cutting punch 22 has a V-shaped blade for cutting out the V-shaped edge; the cutting die 32 is a V-shaped cavity to fit the cutting punch 22. Thus, the end cut by the cutting punch 22 and the cutting die 32 is a V-shaped tip. Of course, in other embodiments, the structure of the cutting punch 22 and the cutting die 32 can be appropriately adjusted according to the shape of the end to be cut.

[0025] Specifically, the cutting punch 22 is located below the first guide constriction 21, and the cutting die 32 is located below the second guide constriction 31. Of course, in other embodiments, the configuration can be reversed, with the cutting punch 22 and cutting die 32 at the top, the first guide constriction 21 below the cutting punch 22, and the second guide constriction 32 below the cutting die 31. This is acceptable as long as the cable tie is long enough to be positioned by the lower first and second guide constrictions 21.

[0026] Specifically, the opening and closing actuator 10 is an opening and closing cylinder, which can be purchased directly from the market.

[0027] Furthermore, it also includes a mounting bracket with a fixed plate 60. The guide rail 40 is fixed to the surface of the fixed plate 60, and the opening / closing actuator 10 is fixed to the bottom surface of the fixed plate 60. The fixed plate 60 has a clearance window 61. The first driving end of the opening / closing actuator 10 is connected to the punch portion 20 through a first connecting rod 11, and the second driving end of the opening / closing actuator 10 is connected to the die portion 30 through a second connecting rod 12. Both the first connecting rod 11 and the second connecting rod 12 pass through the clearance window 61. In this way, the installation and connection of each part are realized, saving floor space.

[0028] Furthermore, it also includes a buffer 50. Specifically, the buffer 50 adopts a buffer cylinder in the prior art, and the buffer 50 corresponds to the outer side of one of the driving ends of the opening and closing driver 10. In this way, when the opening and closing driver 10 drives the cutting punch 20 and the cutting die 30 to separate to their outermost positions, they will be cushioned by the buffer 50, which provides good protection.

[0029] A positioning structure is also provided between the punch portion 20 and the die portion 30. This positioning structure includes a positioning hole 23 in the punch portion 20 and a positioning pin 33 in the die portion 30, with the positioning pin 33 facing the positioning hole 23. When the punch portion 20 and the die portion 30 approach each other, the positioning pin 33 first inserts into the positioning hole 23 to achieve precise positioning. After positioning, the cutting punch 22 can accurately penetrate into the cutting die 32. Of course, in other embodiments, the positions of the positioning pin 33 and the positioning hole 23 of the positioning structure can be interchanged.

[0030] Furthermore, it also includes a first protective cover 71 and a second protective cover 72. The first protective cover 71 covers the punch portion 20, and the second protective cover 72 covers the die portion 30. The first protective cover 71 and the second protective cover 72 are spaced apart so that a cutting operation space 70 is formed between the first protective cover 71 and the second protective cover 72. The cable tie is transported into the cutting operation space 70. When the opening and closing driver 10 drives the punch portion 20 and the die portion 30 to come together, they are exposed in the cutting operation space 70, thereby cutting the cable tie. After completion, the punch portion 20 and the die portion 30 separate from each other until they retract into their respective protective covers, which plays a good protective role.

[0031] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
