Description

Technical Field

[0001] This utility model relates to the field of cable tie machine technology, specifically a cutting mechanism for a cable tie machine. Background Technology

[0002] Automatic cable tie cutting machine is a high-efficiency and precise automated equipment, specially designed for cutting various types of cable ties such as nylon, stainless steel, and plastic to a fixed length. It is suitable for fields such as electronic assembly, automotive wiring harnesses, and power engineering. The cable ties need to be cut by a cutting mechanism during the transmission process.

[0003] The existing cable tie cutting mechanism uses an upper blade and a lower anvil to cut the cable ties that have been fed into place. During the cutting process, pressure must first be applied to the cable tie by the upper blade, and the cable tie can only be completely cut after the pressure reaches a certain value. At this time, the cable tie undergoes some deformation during the initial compression, which results in uneven cut lengths and the possibility of burrs on the edges of the cable tie, reducing product quality and affecting subsequent usage efficiency. This needs to be optimized and improved. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting mechanism for a cable tie machine to solve the problem mentioned in the background art that cable ties are difficult to cut stably during the cutting process, and are prone to uneven lengths and edge burrs, which affect the efficiency of subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting mechanism for a cable tie machine, comprising: a support frame, a transmission plate disposed at the rear of the top end of the support frame, and a connecting frame disposed at the middle of the top end of the support frame, wherein a conveying roller is disposed on the inner side of the connecting frame, and further comprising an anti-deviation cutting component and a movement protection component:

[0009] Preferably, a snap-fit ​​block is connected to the inner side of the lower pressure plate, a connecting rod is connected to the inner side of the snap-fit ​​block, and a grooved soft pad is connected to the bottom end of the snap-fit ​​block.

[0010] Preferably, a lower anvil is installed on one side of the top of the support frame, and the guide tube is disposed at the top of the lower anvil.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a cutting mechanism for a cable tie machine, including: a support frame 1, a transmission plate 2 is provided at the rear of the top end of the support frame 1, and a connecting frame 3 is provided at the middle of the top end of the support frame 1, and a conveying roller 4 is provided on the inner side of the connecting frame 3.

[0025] An anti-deviation cutting assembly is provided at the front of the top of the support frame 1. The anti-deviation cutting assembly includes an upper cutter 8, and a lower pressure plate 11 is provided on one side of the upper cutter 8. A guide tube 7 is provided at the bottom of the lower pressure plate 11. The anti-deviation cutting assembly is used to prevent deviation when cutting cable ties.

[0026] A movable protective component is provided on one side of the top of the support frame 1. The movable protective component includes a limiting block 16, and a support plate 17 is provided at the front end of the limiting block 16. A sliding frame 18 is provided at the top of the support plate 17. The movable protective component is used for buffer protection during cutting and moving adjustment.

[0027] Specifically, such as Figure 3 As shown, a telescopic cylinder 5 is installed at the front of the top of the support frame 1, and an upper cutter 8 is set at one end of the telescopic cylinder 5. The telescopic cylinder 5 is used to control the upper cutter 8 to lift and lower, so as to facilitate the cutting of cable ties.

[0028] Specifically, such as Figure 3As shown, the upper cutter 8 is connected to a fixed plate 9 at its rear end, and a guide rod 10 is connected to the inner side of the fixed plate 9. The lower pressure plate 11 is connected to the bottom end of the guide rod 10. The lower pressure plate 11 and the fixed plate 9 are connected by the guide rod 10 to facilitate the control of the position of the lower pressure plate 11.

[0029] Specifically, such as Figure 3 As shown, a snap-fit ​​block 13 is connected to the inner side of the lower pressure plate 11, and a connecting rod 12 is connected to the inner side of the snap-fit ​​block 13. A grooved soft pad 14 is connected to the bottom end of the snap-fit ​​block 13. The snap-fit ​​block 13 and the grooved soft pad 14 are slidably snapped into the inner side of the lower pressure plate 11, and then fixedly connected by the connecting rod 12. This can improve the anti-slip effect to a certain extent, and the snap-fit ​​connection method is also convenient for replacement.

[0030] Specifically, such as Figure 2 As shown, a lower anvil 6 is installed on one side of the top of the support frame 1, and a guide tube 7 is set on the top of the lower anvil 6. The lower anvil 6 supports the cable tie and guides the transmission position through the guide tube 7.

[0031] Specifically, such as Figure 2 As shown, the front end of the lower anvil 6 is connected to the feeding guide plate 15, and the cut cable ties slide out and are collected through the feeding guide plate 15.

[0032] Specifically, such as Figure 4 As shown, the limiting block 16 is fixedly connected to the bottom of one side of the telescopic cylinder 5. The top of the sliding frame 18 is connected to the protective top plate 19, and the inner side of the sliding frame 18 is provided with an inner protective pad 20. The sliding frame 18 and the support plate 17 are slidably connected, and the support plate 17 and the inner protective pad 20 are elastically connected. When the upper cutter 8 moves downward, it squeezes the sliding frame 18. The sliding frame 18 is attached to the support plate 17 through the protection on the inner and outer sides to limit and protect, thereby improving the accuracy of the cutting position of the upper cutter 8.

[0033] In this embodiment: During the cable tie cutting process, a guide tube 7 is set to guide the cable tie, and then the lower pressure plate 11 and the grooved soft pad 14 at the bottom position first contact the cable tie to achieve a certain pressing and positioning function, so as to prevent the upper cutter 8 from deviating when cutting the cable tie. When the upper cutter 8 is adjusted and moved, a limit block 16 is set at the bottom to connect with the support plate 17 for limit protection. During the limit contact process, the rubber protective top plate 19 and the inner protective pad 20 are connected for protection.

[0034] Specifically, the solution is as follows: When equidistantly cutting the cable ties, the cable ties are conveyed at a uniform speed through the conveyor plate 2 and the conveyor roller 4, passing through the guide tube 7 and resting on the lower anvil 6. After being conveyed to the appropriate position, the telescopic cylinder 5 drives the upper cutter 8 to descend. At this time, the lower pressure plate 11, which is lower than the upper cutter 8, connects the locking block 13 and the grooved soft pad 14 to first adhere to the cable tie. Under the pressure of the external spring force of the guide rod 10, the cable tie can be initially positioned. Then, the upper cutter 8 adheres to the lower anvil 6 to cut the cable tie. After being cut, the cable ties slide out and are collected through the unloading guide plate 15. At this time, the upper cutter 8 presses the sliding frame 18 as it moves downward. The sliding frame 18 is protected and attached to the support plate 17 by the protective top plate 19 on both the inner and outer sides and the inner protective pad 20, which provides limit protection and improves the accuracy of the cutting position of the upper cutter 8. After the grooved soft pad 14 wears out, it can be replaced by unscrewing the connecting rod 12 and then sliding out the snap-fit ​​block 13 to ensure that the position of the cable tie will not shift during cutting and improve the processing quality.
