[0070] In this embodiment, the rotary support member 2 can adopt the prior art. Refer to the water collecting pipe support device in a water collecting pipe winding film device disclosed in the Chinese patent with the authorization announcement number CN210284704U, or adopt other prior arts, as long as it can support the wound RO membrane assembly 100 and can drive the RO membrane assembly 100 to rotate. Generally, it includes a clamping device for the water collecting pipe that can be inserted into the middle of the RO membrane assembly 100 and a rotating device that drives the clamping device and the RO membrane assembly 100 thereon to rotate together. The structure thereof will not be elaborated in this embodiment.

[0071] Specifically, as Figure 2 , 3 , FIGS. 9, the moving drive mechanism can be the following structure, including:

[0072] A vertical moving seat 7, which is slidably fitted on the frame 1, and the movable seat assembly 6 is slidably fitted on the vertical moving seat 7;

[0073] A vertical moving drive assembly 8, which is connected between the frame 1 and the vertical moving seat 7 to drive the vertical moving seat 7 to move vertically on the frame 1;

[0074] A horizontal moving drive assembly 9, which is connected between the vertical moving seat 7 and the movable seat assembly 6 to drive the movable seat assembly 6 to move horizontally relative to the vertical moving seat 7.

[0075] In this embodiment, the vertical moving drive assembly 8 is a vertical lifting cylinder. The cylinder body part of the vertical lifting cylinder is fixed on the frame 1, and the air rod of the vertical lifting cylinder is connected to the vertical moving seat 7. The vertical moving seat 7 is driven to vertically rise or fall relative to the frame 1 by the extension or retraction of the air rod of the vertical lifting cylinder; the horizontal moving drive assembly 9 is a horizontal moving cylinder.

The cutting movement driving motor 12a is connected to the driving gear 12b, and the toothed belt 12d connects the driving gear 12b and the driven gear 12c. When the cutting movement driving motor 12a operates, it drives the driving gear 12b to rotate. Since the toothed belt 12d is connected to the driving gear 12b and the driven gear 12c, the toothed belt 12d is driven to move, and the toothed belt 12d then drives the cutting base 10 to move, thereby driving the cutting saw 11 on the cutting base 10 to move. During the movement, since the rack 13 meshes with the gear, the cutting saw 11 is driven to rotate, realizing the rotation and movement of the cutting saw 11.

[0086] Specifically, as Figure 9-10 shown, the mesh sheet supply component 4 can have the following structure, including:

[0087] A mesh sheet roller 15 rotatably installed on the movable seat assembly 6;

[0088] A mesh sheet roller rotation driving mechanism connected to the mesh sheet roller 15 to drive the mesh sheet roller 15 to rotate.

[0089] In this embodiment, the mesh roll rotation driving mechanism includes: a mesh roll rotation driving motor 16a, an output shaft gear 16b connected to the output shaft of the mesh roll rotation driving motor 16a, an input shaft gear 16c connected to the mesh roll 15, and a chain 16d connecting the output shaft gear 16b and the input shaft gear 16c; when the mesh roll rotation driving motor 16a operates, it drives the output shaft gear 16b on its output shaft to rotate, and the output shaft gear 16b drives the input shaft gear 16c to rotate through the chain 16d, thereby driving the mesh roll 15 to rotate.

[0090] As Figure 9 shown, in this embodiment, a mesh pressing roll 24 is further provided below the mesh roll 15. The mesh pressing roll 24 is fixed on two supports 25. The supports 25 are slidably fitted on the movable seat assembly 6, and a lifting cylinder 26 is hinged to each of the two supports 25 below. The cylinder body of the lifting cylinder 26 is fixedly connected to the movable seat assembly 6, and the lifting air rod 26a of the lifting cylinder 26 is hinged to the support 25; when the lifting cylinder 26 acts, the lifting air rod 26a extends or retracts, and the lifting air rod 26a drives the support 25 to slide vertically relative to the movable seat assembly 6, thereby driving the mesh pressing roll 24 to move vertically closer to or away from the mesh roll 15 to press or loosen the mesh.

[0091] Specifically, as Figure 11-14 shown, the welding component 5 may have the following structure, including:

[0092] a heating strip 17 adapted to be energized and heated;

[0093] two strip moving mechanisms connected to the heating strip 17 to drive the heating strip 17 to move closer to or away from the welding part to be welded of the RO film assembly 100 after cutting and trimming for welding the welding part.

[0094] Specifically, as Figure 11-14 shown, the strip moving mechanism may have the following structure, including:

[0095] a piston cylinder 18;

[0096] a swing rod 19 hinged in the middle on the frame 1. One end of the swing rod 19 is hinged to the piston rod 18a of the piston cylinder 18, and the other end of the swing rod 19 is provided with a receiving chute 19a;

[0097] a strip guide block 20. The strip guide block 20 is installed on the heating strip 17. A sliding roller 21 and two guide rollers 22 are rotatably connected to the strip guide block 20, and the sliding roller 21 is slidably fitted in the receiving chute 19a;

[0098] a guide chute 23 is provided on the frame 1, and the guide rollers 22 are slidably fitted in the guide chute 23; wherein,

[0099] Through the cooperation of the guiding chute 23 and the guiding roller 22, as well as the cooperation of the sliding roller 21 and the accommodating chute 19a, it is ensured that the heating surface of the heating strip 17 forms good contact with the part to be welded.

[0100] In this embodiment, the piston cylinder 18 acts, and the piston rod 18a extends or retracts to drive the swing rod 19 to swing. Since the sliding roller 21 on the strip guiding block 20 is slidably fitted in the accommodating chute 19a, when the swing rod 19 swings, it drives the strip guiding block 20 to move relative to the frame along the guiding chute 23, thereby driving the heating strip 17 to move, so that the heating strip 17 approaches the part to be welded of the RO film assembly 100 after trimming and cutting for welding or moves away from it.

[0101] As Figure 14 shown, in this embodiment, the guiding chute 23 is of a V-shaped structure.

[0102] The RO film assembly 100 to be trimmed can be installed on the rotary support member 2. The cutting member 3 is used to trim and cut one RO film layer on the RO film assembly 100. After completion, the RO film assembly 100 is rotated by a certain angle through the rotary support member 2, and the cutting member 3 is used to trim and cut the next RO film layer on the RO film assembly 100. The trimming and cutting of all RO film layers are completed in sequence. Then, the mesh is supplied through the mesh supply member 4. One end of the mesh on the mesh supply member 4 is welded to the RO film assembly 100 after trimming and cutting through the welding member 5. Then, the RO film assembly 100 is rotated through the rotary support member 2 so that the mesh is wound and wrapped around the RO film assembly 100 after trimming and cutting, and the mesh is wound at least one week. Then, the mesh is cut by the cutting member 3 to form the other end of the mesh, and the other end of the mesh is welded to the RO film assembly 100 after trimming and cutting through the welding member 5, thus completing the entire trimming work on the RO film assembly 100.
