The mobile drive mechanism 3 is used to drive the mobile seat 2 to move to the forward position when the RO membrane filter element 4 moves to the tube cutting position so that the cutting mechanism 200 and the central tube in the RO membrane filter element 4 are matched in place. The mobile drive mechanism 3 is also used to drive the mobile seat 2 to move to the backward position so that the cutting mechanism 200 is separated from the central tube in the RO membrane filter element 4.

[0069] The chamfering mechanism 300 is connected to the moving seat 2. When the RO membrane filter element 4 moves to the chamfering position, the chamfering mechanism 300 is aligned with the RO membrane filter element 4 and is used to chamfer the central tube in the RO membrane filter element 4. Specifically, when working, the RO membrane filter element 4 is placed on the clamping mechanism 100, and the clamping mechanism 100 clamps the RO membrane filter element 4 and drives the clamped RO membrane filter element 4 to move to the tube cutting position along the Y direction.

After the cutting is completed, the mobile drive mechanism 3 drives the mobile seat 2 to move to the retreat position to separate the cutting mechanism 200 from the central tube in the RO membrane filter element 4, and then the clamping mechanism 100 drives the RO membrane filter element 4 to move to the chamfering position along the Y direction, at which time the chamfering mechanism 300 is aligned with the RO membrane filter element 4 and chamfers the cut on the central tube in the RO membrane filter element 4.

[0075] like Figure 2 , 3 As shown, the mounting seat 6 has loading and unloading stations during the movement along the Y direction;

[0076] The frame 1 is also connected to a positioning plate 10.

Then the pneumatic clamp 7 drives the upper clamp block 8 and the lower clamp block 9 to move toward each other to clamp the RO membrane filter element 4, and then the first linear module 5 drives the mounting seat 6 to move along the Y direction and then drives the clamped RO membrane filter element 4 to move along the Y direction to the tube cutting position, at which time the cutting mechanism 200 is aligned with the RO membrane filter element 4, and the mobile drive mechanism 3 drives the mobile seat 2 to move to the forward position so that the cutting mechanism 200 and the central tube in the RO membrane filter element 4 are in place, and then the cutting mechanism 200 starts working and cuts the central tube in the RO membrane filter element 4. After the cutting is completed, the mobile drive mechanism 3 drives the mobile seat 2 to move to the retreat position so that the cutting mechanism 200 is separated from the central tube in the RO membrane filter element 4, and then the first linear module 5 drives the mounting seat 6 to move along the Y direction again and then drives the clamped RO membrane filter element 4 to move along the Y direction to the chamfering position, at which time the chamfering mechanism 300 is aligned with the RO membrane filter element 4 and chamfers the central tube in the RO membrane filter element 4. After the chamfering is completed, the first linear module 5 drives the mounting seat 6 to move along the Y direction back to the loading and unloading station, and then the pneumatic clamp 7 drives the upper clamp block 8 and the lower clamp block 9 to move back and forth to release the RO membrane filter element 4, and then the RO membrane filter element 4 can be removed.

[0082] The cylinder 16 is connected to the moving seat 2 and is connected to the chamfering slide 15. The cylinder 16 is used to drive the chamfering slide 15 to move along the X direction and thereby drive the chamfering knife 18 to move against the center tube in the RO membrane filter element 4. Specifically, when the RO membrane filter element 4 moves to the chamfering position, the cylinder 16 extends to drive the chamfering slide 15 to move along the X direction and thereby drive the chamfering knife 18 to move against the center tube in the RO membrane filter element 4. The chamfering motor 17 drives the chamfering knife 18 to rotate and chamfer the incision on the center tube. Then, the cylinder 16 retracts to drive the chamfering slide 15 to move along the X direction and thereby drive the chamfering knife 18 to separate from the center tube in the RO membrane filter element 4.

[0089] A transmission structure 23, wherein the transmission structure 23 is disposed between the hollow main shaft 19 and the sliding sleeve assembly 22 so that the hollow main shaft 19 drives the sliding sleeve assembly 22 to rotate synchronously;

[0090] A connecting rod 24 corresponding to the tool assembly 21, wherein one end of the connecting rod 24 is connected to the corresponding tool assembly 21;

[0091] A transmission member 25 corresponding to the connecting rod 24, wherein the transmission member 25 is connected to the other end of the corresponding connecting rod 24;

On the other hand, it drives the sleeve assembly 22 to rotate synchronously through the transmission structure 23, and then drives the drive plate 26, the connecting rod 24 and the transmission member 25 to rotate synchronously together. Therefore, the hollow main shaft 19, the cutting disc 20, the tool assembly 21, the connecting rod 24, the transmission member 25, the drive plate 26 and the sleeve assembly 22 all rotate synchronously at the same speed. Then the feed drive mechanism 400 drives the drive ring 27 to move forward axially. The drive ring 27 is rotationally connected to the sleeve assembly 22.

[0099] The driving ring 27 is rotatably connected to the outer sleeve 28 and is located outside the outer sleeve 28;

[0100] The driving plate 26 is connected to the outer periphery of the outer sleeve 28; specifically, the hollow main shaft 19 drives the inner sleeve 29 to rotate synchronously through the transmission structure 23, and then drives the outer sleeve 28 to rotate synchronously, and then drives the driving plate 26 to rotate synchronously through the outer sleeve 28. More specifically, when the driving ring 27 moves in the axial direction, it drives the outer sleeve 28 to move, and then drives the inner sleeve 29 and the driving plate 26 to move in the axial direction through the outer sleeve 28.
