[0024] It should be noted that the utility model is equipped with a PLC controller, and an infrared sensor for detecting the position of the discharge ring 11 is provided on the top of the support frame 2. There are three discharge rings 11, namely, the first discharge ring, the second discharge ring and the third discharge ring. Figure 1As shown, the No. 2 discharge ring is located directly below the cutter 4, the No. 1 discharge ring is located at the loading station, the No. 3 discharge ring is located below the unloading station and the vacuum suction cup 9, and the infrared sensor detects the position signal of the connecting rod between the discharge ring 11 and the rotating disk 10, and the No. 2 hydraulic cylinder 14 drives the support ring 15 to rise upward to support the bottom of the No. 2 discharge ring, and the No. 1 hydraulic cylinder 3 drives the cutter 4 to move downward. After the positioning block 5 presses the workpiece, the cutter 4 continues to move downward to cut the edge of the workpiece. During the descent of the cutter 4, the vacuum suction cup 9 moves to the inner wall of the No. 3 discharge ring, and the vacuum suction cup 9 absorbs the workpiece. When the No. 1 hydraulic cylinder 3 drives the cutter 4 to reset, and the No. 2 hydraulic cylinder 14 drives the support ring 15 to reset, the cutter 4 passes The connecting beam 6 drives the unloading chute 7 to rise, thereby lifting the workpiece, and then the unloading cylinder 8 pushes the vacuum suction cup 9 forward to the receiving conveyor belt. The driving part drives the three unloading rings to rotate through the rotating disk 10, and the material to be processed on the top of the No. 1 unloading ring is placed on the top of the support ring 15, and the workpiece on the top of the No. 2 unloading ring moves to the unloading station, and this cycle is used to complete the continuous trimming operation. By setting up multiple unloading rings to work in a cycle, high-throughput production can be achieved by continuously and automatically cutting, transporting and unloading workpieces. The linkage between the cutter 4 and the unloading chute 7 realizes automatic mobile unloading, and most dangerous operations such as cutting are completed by machines, reducing the need for workers to directly contact dangerous machinery, thereby reducing the accident rate in the workplace.

[0025] See also Figure 2 As shown, two recycling grooves 12 are provided on the top of the workbench 1 , and a recycling bucket 13 is detachably connected to the inside of the workbench 1 at positions corresponding to the recycling grooves 12 .

[0026] It should be noted that the utility model directly collects the waste generated during the cutting or processing process through the recycling groove 12, which can prevent the waste from being scattered in the work area and keep the working environment clean; the waste is automatically collected into the recycling bin 13, which reduces the time for workers to manually clean up the waste, thereby improving the overall work efficiency. The detachable recycling bin 13 makes the transfer, transportation and reprocessing of the waste more convenient.

[0027] See also Figure 1 , 2 As shown, the support frame 2 includes a No. 1 pillar and a No. 2 pillar and a crossbeam fixedly connected to the top of the two pillars, and two No. 1 hydraulic cylinders 3 are fixedly connected to the top of the crossbeam. The output end of the No. 1 hydraulic cylinder 3 is fixedly connected to the cutter 4. The inner diameter of the cutter 4 is the same as the outer diameter of the discharge ring 11. The top of the positioning block 5 passes through the top of the cutter 4, and a return spring 19 is provided on the outside of the positioning block 5 and inside the cutter 4.

[0028] It should be noted that the first hydraulic cylinder 3 of the utility model realizes the cutting of the workpiece through the cooperation of the cutter 4 and the discharge ring 11. During the cutting process, the bottom of the positioning block 5 is lower than the bottom of the cutter 4, so that the positioning block 5 first contacts the workpiece, and the positioning block 5 presses the workpiece. When the cutter 4 continues to move downward, the cutter 4 compresses the reset spring 19. The reset spring 19 presses the workpiece through the positioning block 5 to prevent it from being offset during cutting. The inner diameter of the cutter is the same as the outer diameter of the discharge ring, and the part extending out of the discharge ring 11 is completely cut, ensuring the accurate alignment of the material during the cutting process and reducing errors.

[0029] See also Figure 1 , 2 As shown, a No. 2 hydraulic cylinder 14 is fixedly connected inside the workbench 1 , and a support ring 15 is fixedly connected to the output end of the No. 2 hydraulic cylinder 14 , and the support ring 15 is located below the cutter 4 .

[0030] It should be noted that the No. 2 hydraulic cylinder 14 of the utility model drives the support ring 15 to rise, and the support ring 15 supports the discharge ring 11 from the bottom to ensure that the discharge ring 11 will not be deformed against the rotating disk 10 when subjected to the downward pressure of the cutter 4, thereby ensuring the stability and accuracy of cutting.

[0031] See also Figure 1 , 2 As shown in FIG. 4 , the rotating disk 10 is rotatably mounted on the outer side of the No. 1 pillar, a driven gear 16 is fixedly connected to the bottom of the rotating disk 10, and a driving portion includes a driving motor 18 fixedly connected to the outer side of the No. 1 pillar, and an output end of the driving motor 18 is fixedly connected to a driving gear 17, and the driving gear 17 is meshingly connected to the driven gear 16.

[0032] It should be noted that, in the utility model, when multiple discharge rings 11 need to switch positions, the driving motor 18 drives the active gear 17 to rotate, the active gear 17 drives the driven gear 16 to rotate, the driven gear 16 drives the rotating disk 10 to rotate, and the rotating disk 10 drives different discharge rings 11 to move to different positions, thereby realizing the position switching of the discharge ring 11, thereby realizing loading, processing and unloading.

[0033] See also Figure 1 , 2 As shown, the unloading chute 7 is slidably connected to the outer side of the No. 1 pillar, and the top of the unloading chute 7 is fixedly connected to a unloading cylinder 8, and the output end of the unloading cylinder 8 is fixedly connected to the vacuum suction cup 9.

[0034] It should be noted that, in the utility model, when the cutter 4 is cutting downward, the cutter 4 drives the unloading chute 7 to move downward through 6, and the vacuum suction cup 9 absorbs the workpiece and then the cutter 4 rises after the cutting is completed, and then the unloading cylinder 8 pushes the vacuum suction cup 9 along the unloading chute 7, so as to place the vacuum suction cup 9 with the workpiece in the receiving position.
