[0030] The spindle motor 2 is powered by an external power source, and a control switch is provided between the external power source and the spindle motor 2 .

[0031] The spindle motor 2 is connected to the synchronous belt 3 via a transmission wheel. The cutter disc assembly 4 is located at the bottom of the machine head body 1, and the cutter disc assembly 4 includes a large cutter disc and a small cutter disc.

[0033] The punching assembly 6 is located at one side of the machine head body 1 , and a lead counterweight block 71 and an iron balance block 72 are arranged inside the eccentric wheel assembly 7 .

[0034] The working principle of the head structure of the intelligent cutting machine provided by the present invention is as follows:

[0035] The output end of the spindle motor 2 rotates to drive the synchronous belt 3 to rotate, and the rotation of the synchronous belt 3 drives the eccentric wheel assembly to operate. The lead counterweight block 71 and the iron balance block 72 are combined to reduce the eccentric operation jitter problem. The cutter disc assembly 4 adopts a large and small cutter disc structure.

The large knife disc presses the cutting material to prevent movement, and the small knife disc performs cutting in straight lines, curves, rotations, etc., making the cutting more stable and more accurate.

[0038] Second embodiment

[0039] See also Figure 5 , Figure 6 and Figure 7 Based on the head structure of an intelligent cutting machine provided by the first embodiment of the present application, the second embodiment of the present application proposes another head structure of an intelligent cutting machine. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0040] Specifically, the difference of the head structure of the intelligent cutting machine provided in the second embodiment of the present application is that, in the head structure of the intelligent cutting machine, a replacement component 8 of the synchronous belt 3 is fixedly installed on the head main body 1, and the replacement component 8 includes a mounting plate 81, and a push-pull rod 82 is slidably connected to the mounting plate 81, and the push-pull rod 82 is internally threadedly connected to a threaded rod 83, and one end of the threaded rod 83 is rotatably connected to a transmission block 84, and the push-pull rod 82 is internally slidably connected to a sliding groove 85, and the sliding groove 85 is internally slidably connected to a support rod 86, and one end of the support rod 86 is fixedly installed with a transmission wheel 87, and the surface of the push-pull rod 82 is sleeved with a pull spring 88, and one end of the push-pull rod 82 is rotatably connected to a transmission plate 89, and a connecting rod 810 is fixedly installed on the transmission plate 89, and a transmission block 811 is fixedly installed on the mounting plate 81, and a positioning groove 812 is provided on the transmission block 811.

[0041] When the transmission wheel 87 no longer pulls the synchronous belt 3 , the synchronous belt 3 is in a relaxed state, and thus the length of the synchronous belt 3 that needs to be rotated is slightly longer than that of the normally connected synchronous belt 3 .

[0042] The mounting plate 81 is fixedly mounted on the machine head body 1 , and the mounting plate 81 is located at one side of the synchronous belt 3 , and one end of the push-pull rod 82 is located at one side of the synchronous belt 3 .

[0043] The push-pull rod 82 can drive the transmission wheel 87 to move, and the transmission wheel 87 drives the synchronous belt 3 to move rightward.

[0044] One end of the threaded rod 83 passes through the right side of the push-pull rod 82 and extends to the inside of the push-pull rod 82 . The transmission block 84 is located inside the sliding groove 85 , and the transmission block 84 is slidably connected to the inner surface of the sliding groove 85 .

[0045] When the tightness of the synchronous belt 3 needs to be fine-tuned, the threaded rod 83 is rotated. The rotation of the threaded rod 83 causes the threaded rod 83 to move, and the movement of the threaded rod 83 drives the transmission block 84 to move. The movement of the transmission block 84 drives the transmission wheel 87 to move, thereby fine-tuning the tightness of the synchronous belt 3.

[0046] The transmission wheel 87 is located on the left side of the synchronous belt 3, and the transmission wheel 87 is rotationally connected to the synchronous belt 3. The pulling spring 88 is located in the middle of the mounting plate 81 and the transmission plate 89, and the two ends of the pulling spring 88 are fixedly connected to the surface of the mounting plate 81 and the surface of the transmission plate 89 respectively.

[0047] A rotating disk is provided on one side of the transmission plate 89, and one end of the pull spring 88 is connected to the transmission plate 89 via the rotating disk, so that when the transmission plate 89 rotates, the pull spring 88 will not be driven to rotate.

[0048] There are two connecting rods 810 in total. The two connecting rods 810 are symmetrically distributed on both sides of the transmission plate 89 . The connecting rods 810 are slidably connected to the surface of the transmission block 811 .

[0049] The two connecting rods 810 support the two ends of the transmission plate 89 .

[0050] The transmission block 811 is arc-shaped. The connecting rod 810 is located on one side of the transmission block 811 . One end of the connecting rod 810 is matched with the positioning groove 812 .

[0051] The connection between the connecting rod 810 and the positioning groove 812 is to position the connecting rod 810 so that the connecting rod 810 cannot rotate. The arc-shaped transmission block 811 can make the connecting rod 810 move left or right along the arc of the transmission block 811 when rotating and moving on the transmission block 811.

[0052] Working principle:

[0053] When it is necessary to quickly tighten the synchronous belt 3, rotate the transmission plate 89. The rotation of the transmission plate 89 will drive the connecting rod 810 to rotate. The rotation of the connecting rod 810 will cause the connecting rod 810 to rotate along the transmission block 811, thereby causing the connecting rod 810 to move to the right. The movement of the connecting rod 810 to the right will drive the transmission plate 89 to move to the right. The rotation and movement of the transmission plate 89 to the right will drive the push-pull rod 82 to move to the right. The movement of the push-pull rod 82 to the right will drive the transmission wheel 87 to move to the right, thereby allowing the transmission wheel 87 to drive the synchronous belt 3 to move to the right, thereby quickly tightening the synchronous belt 3. After the connecting rod 810 rotates, it will pull the push-pull rod 88 to pull the transmission plate to the right 89, so that the transmission plate 89 drives the connecting rod 810 to enter the interior of the positioning groove 812, and then the connecting rod 810 can be positioned after rotation, and when the synchronous belt 3 needs to be replaced, the transmission plate 89 is pulled, so that the transmission plate 89 drives the connecting rod 810 and the positioning groove 812 to no longer be engaged, and then the transmission plate 89 is rotated in the opposite direction, so that the transmission plate 89 drives the connecting rod 810 to rotate, and then the transmission block 811 no longer squeezes the connecting rod 810, and then the push-pull rod 82 moves to the left under the pull of the pull spring 88, so that the transmission wheel 87 no longer squeezes the synchronous belt 3, and then the synchronous belt 3 is loosened, and then the synchronous belt 3 can be replaced.

[0054] Beneficial effects:

[0055] By pulling the transmission plate 89, the transmission plate 89 drives the connecting rod 810 and the positioning groove 812 to no longer be engaged, and the transmission plate 89 can be rotated. The rotation of the transmission plate 89 will drive the connecting rod 810 to rotate. The rotation of the connecting rod 810 will make the transmission block 811 no longer squeeze the connecting rod 810, and then the pulling spring 88 pulls the transmission plate 89, so that the transmission plate 89 drives the push-pull rod 82 to move to the left, and then the transmission wheel 87 no longer pulls the synchronous belt 3, so that the synchronous belt 3 becomes loose, thereby facilitating the replacement of the synchronous belt 3 and avoiding the existing synchronous belt 3 being very tight, which makes it inconvenient to replace the synchronous belt 3.
