[0022] The present invention is further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 6 As shown, an efficient circle cutting device includes a rotatable fixing device 1, a cutting platform 2 and a cutting device 3. The fixing device 1 is connected to a second motor 4 to achieve a rotation effect. The fixing device 1 is arranged on the cutting platform 2, and the cutting device 3 is arranged on one side of the fixing device 1. The fixing device 1 is used to fix a circular cylinder 5 and drive the circular cylinder 5 to rotate. The cutting device 3 includes a sawtooth assembly 6 and a rotatable sawtooth arm 7. The sawtooth assembly 6 includes a plurality of stacked saw teeth 8. The gap between the saw teeth 8 is the same as the thickness of the circle to be cut. The sawtooth arm 7 is axially connected to the cutting platform 2. The sawtooth arm 7 rotates to move the sawtooth assembly 6 to the fixing device 1 to cut the circular cylinder 5. Multiple stacked saw teeth 8 can cut a circular cylinder 5 into multiple circles at one time. The rotation of the fixing device 1 helps the sawtooth assembly 6 to cut around the circular cylinder 5 without manually rotating the fixing device 1.

[0024] The positions of the rotating mechanism 4 and the sawtooth arm 7 of the fixing device 1 are sensed. When the sawtooth arm 7 rotates to the sensing position, the rotating mechanism 4 rotates to drive the fixing device 1 to rotate. When the sawtooth arm 7 does not reach the sensing position, the rotating mechanism 4 will not rotate, so as to prevent the rotating mechanism 4 from idling and save power consumption. An axial connection part 9 is provided near the rear end of the sawtooth arm 7, and a travel switch 10 is provided between the rear end of the sawtooth arm 7 and the cutting platform 2. During the rotation of the sawtooth arm 7 along the axial connection part 9, the travel switch 10 is deformed. When the travel switch 10 is deformed to a certain extent, the linked rotating mechanism 4 is opened to rotate the rotating mechanism 4. In this scheme, the travel switch 10 is used to control the position of the trigger point.

[0025] like Figure 1-Figure 4As shown, the fixing device 1 includes a plurality of fixing arms 11 and a spreading mechanism 12. The spreading mechanism 12 includes a top column 13 that can move up and down and a plurality of spreading plates 14. The top column 13 is arranged at the central position of the plurality of spreading plates 14, and the outer end of the spreading plate 14 is connected to the fixing arm 11; the top column 13 moves upward to push the spreading plate 14 to move toward the circumference, thereby driving the fixing arm 11 to move toward the circumference and fix the circular cylinder 5. The upper end of the top column 13 is an arc-shaped transition structure that is narrow at the top and wide at the bottom. The upward movement will spread the spreading plate 14. The circular cylinder 5 is sleeved on the outside of the fixing arm 11 to achieve a fixing effect, which can be suitable for fixing circular cylinders 5 with different inner diameters. A protective layer 15 is arranged on the outside of the fixing arm 11 to prevent the fixing arm 11 from being cut. The protective layer 15 can be made of wood material, which is low in cost and easy to manufacture.

[0026] like Figure 1-Figure 6 As shown, a first push cylinder 17 is also provided between the sawtooth arm 7 and the cutting platform 2. The contraction of the first push cylinder 17 drives the sawtooth assembly 6 to move toward the fixing device 1. A trigger switch 16 is also provided between the sawtooth arm 7 and the cutting platform 2. The trigger switch 16 is linked to the first push cylinder 17. When the sawtooth assembly 6 is about to contact the fixing device 1, the trigger switch 16 is activated to make the first push cylinder 17 push the sawtooth arm 7 in the opposite direction to return to the initial position. The trigger switch 16 can be a trigger part A and a trigger part B. After the trigger body A and the trigger part B contact, a trigger is generated. The trigger switch 16 is activated and makes the first push cylinder 17 push the sawtooth arm 7 in the opposite direction to return to the initial position. When the trigger switch 16 is activated, the sawtooth assembly 6 has completely cut the circular cylinder 5 and can be reset to prepare for the next cutting.

[0027] The sawtooth assembly 6 is connected to the first motor 17 and rotated by the first motor 17, and the rotatable fixing device 1 is connected to the second motor 4 and rotated by the second motor 4. The top column 13 is connected to the second push cylinder 18 and is arranged below the cutting platform 2. Figure 4 , Figure 6 As shown, a first switch 19 , a second switch 20 and a third switch 21 are provided on the cutting platform 2 , the first switch 19 controls the rotation of the sawtooth assembly 6 , the second switch 20 is used to control the start of the fixing device 1 , and the third switch 21 is used to control the rotation of the sawtooth arm 7 .

[0028] The above is a detailed introduction to the efficient ring cutting equipment provided by the present invention. The principles and implementation methods of the present invention are described in detail using specific examples. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
