[0037] This embodiment provides a cable tie device with adjustable cutting length. The cable tie is fed to the second feed gun chamber 5 through the pneumatic feeding channel 21 by air blowing from an external air source. At the same time, the first drive unit 6 and the second drive unit 7 drive the first feed gun chamber 4 and the second feed gun chamber 5 to rotate respectively. The cable tie will circle the inner wall of the first feed gun chamber 4 and the second feed gun chamber 5, and then the tail of the cable tie will be inserted into the head of the cable tie. At the same time, the tail of the cable tie passes through the head of the cable tie and is inserted between the first tension wheel 22 and the second tension wheel 31. Then, the first tension wheel 22 is driven to rotate by the stepper motor 81, so that the cable tie is tightened and then cut. Before cutting, the position of the cable tie can be changed by reversing the stepper motor 81, thereby changing the cutting position and adjusting and controlling the reserved cutting length.

[0038] In some embodiments, the third drive unit 8 further includes a first linkage gear 82, a second linkage gear 83, a third linkage gear 84, a fourth linkage gear 85, a fifth linkage gear 86, and a sixth linkage gear 87; the output end of the stepper motor 81 is connected to the first linkage gear 82, the second linkage gear 83 is rotatably connected to the first mounting part 2, the third linkage gear 84 is rotatably connected to the first mounting part 2, the fourth linkage gear 85 is rotatably connected to the first mounting part 2, the fifth linkage gear 86 rotates synchronously with the first tensioning wheel 22 via a connecting shaft 88, and the sixth linkage gear 87 rotates synchronously with the second tensioning wheel 31 via a connecting shaft 88; the first linkage gear 82 meshes with the second linkage gear 83, the second linkage gear 83 meshes with the third linkage gear 84, the third linkage gear 84 meshes with the fourth linkage gear 85, the fourth linkage gear 85 meshes with the fifth linkage gear 86, and the fifth linkage gear 86 can mesh with the sixth linkage gear 87. Specifically, in this embodiment, the stepper motor 81 drives the first linkage gear 82 to rotate, the first linkage gear 82 drives the second linkage gear 83 to rotate, the second linkage gear 83 drives the third linkage gear 84 to rotate, the third linkage gear 84 drives the fourth linkage gear 85 to rotate, the fourth linkage gear 85 drives the fifth linkage gear 86 to rotate, the fifth linkage gear 86 drives the sixth linkage gear 87 to rotate, the fifth linkage gear 86 drives the first tensioning wheel 22 to rotate synchronously through the connecting shaft 88, and the sixth linkage gear 87 drives the second tensioning wheel 31 to rotate synchronously through the connecting shaft 88, so that the first tensioning wheel 22 and the second tensioning wheel 31 rotate synchronously, and the rotation directions of the first tensioning wheel 22 and the second tensioning wheel 31 are exactly opposite.

[0039] In some embodiments, such as Figure 2 and 4 As shown, the first driving unit 6 includes a first cylinder 61, which is disposed on the front side of the first mounting part 2, below the first material gun chamber 4. A first hinge plate 62 is hinged to the first material gun chamber 4, and the output end of the first cylinder 61 is hinged to the first hinge plate 62. The first cylinder 61 can drive the first material gun chamber 4 to rotate. Specifically, in this embodiment, the first cylinder 61 drives the first hinge plate 62 to move upward, and then the first hinge plate 62 drives the first material gun chamber 4 to rotate, so that the first material gun chamber 4 can close or separate from the second material gun chamber 5.

[0040] In some embodiments, such as Figure 3 and 5As shown, the second driving unit 7 includes a second cylinder 71, which is disposed on the side of the first mounting part 2. A second linkage plate 72 is disposed at the output end of the second cylinder 71. A second hinge plate 73 is disposed on the rear side of the second material gun chamber 5. The second hinge plate 73 is rotatably connected to the second linkage plate 72, and the second cylinder 71 can drive the second material gun chamber 5 to rotate. A third linkage plate 74 is disposed on the top of the second linkage plate 72. A connecting groove 741 is disposed on the third linkage plate 74. A rotating rod 75 is connected to the second hinge plate 73, and the rotating rod 75 is engaged in the connecting groove 741 and connected to the third linkage plate 74. Specifically, in this embodiment, the second linkage plate 72 moves up and down through the second cylinder 71, thereby causing the third linkage plate 74 to move up and down. The third linkage plate 74 then drives the second hinge plate 73 to rotate, thereby causing the second material gun chamber 5 to rotate, allowing the first material gun chamber 4 to close or separate from the second material gun chamber 5.

[0041] In some embodiments, such as Figure 3 As shown in Figure 5, the first mounting part 2 is also provided with a fixing block 23, and the fixing block 23 has a sliding groove (not shown), in which the second linkage plate 72 can slide. In this embodiment, the second cylinder 71 drives the second linkage plate 72 to slide in the sliding groove, making the second linkage plate 72 more stable when moving up and down.

The slide rail 24 extends vertically, and the bottom of the second mounting part 3 can slide on the slide rail 24. The cable tie device with adjustable cutting length also includes a fourth driving part 9. The fourth driving part 9 includes a fourth cylinder 91, which is disposed on the first mounting part 2. The output end of the fourth cylinder 91 is connected to the bottom of the second mounting part 3 through a fifth linkage plate 92. The fourth cylinder 91 can drive the second mounting part 3 to move upward, causing the first tensioning wheel 22 and the second tensioning wheel 31 to separate, and causing the fifth linkage gear 86 and the sixth linkage gear 87 to separate. Specifically, in this embodiment, by driving the second mounting part 3 upward by the fourth cylinder 91, the first tensioning wheel 22 and the second tensioning wheel 31 are separated. When it is necessary to remove the entire tightened cable tie, there is no need for a retraction step, which improves the separation efficiency after the entire tightening is completed. It should be noted that when the fourth cylinder 91 is driven, the second cylinder 71 is driven synchronously, keeping the entire second mounting part 3 moving upward.

[0043] In some embodiments, such as Figure 1As shown, in order to protect the entire first mounting part 2 and the second mounting part 3, an outer cover 1 is also included, which is disposed on the outside of the first mounting part 2 and the second mounting part 3.

[0044] In some embodiments, such as Figure 4 As shown, the second mounting part 3 is provided with a mounting block 32, which has a mounting groove 321. The mounting groove 321 faces the space between the first tensioning wheel 22 and the second tensioning wheel 31. A detection module (not shown) is provided in the mounting groove 321. The detection module can be a proximity switch or similar device, used to detect whether the tail of the cable tie has passed between the upper and lower tensioning wheels, and whether it has been cut off, etc.
