When performing limit clamping, first place the door and window profile to be processed on the inner side of the straight frame 2 and on the rotating drum surface, and then screw the bidirectional screw rod 6 to drive the limit plate 7 to move back and forth along the inner side of the straight frame 2, approaching or moving away from each other, so that door and window profiles of different sizes can be limited during the transportation process. At the same time, the wheel 9 rotates in the slot 8 to maintain its smoothness when fitting the door and window profiles, preventing blockage and deviation during limiting, thereby affecting the work efficiency of subsequent processing. Secondly, screw the threaded rod 13 to drive the pressure plate 12 to move downward to squeeze the outer top of the door and window profile, so as to further improve the fixing effect of the limit clamping of the door and window profile.

[0022] The outer circumferential surface of the plurality of rollers 3 is provided with a through-type opening 4 at the outer center of the straight frame 2. The inner side of the opening 4 is provided with a mounting box 5. The interior of the mounting box 5 is provided with a cutting and grinding assembly for synchronously trimming and grinding the door and window profiles. The cutting and grinding assembly includes a rotating shaft 21 rotatably connected to both ends of the outer wall of the mounting box 5. A trimming wheel 22 and a grinding wheel 23 are respectively sleeved on the outer circumferential surface of one end of the two rotating shafts 21, and a fixed ring is threadedly sleeved on the outer circumferential surface of the two rotating shafts 21. 24, two sets of fixed rings 24 are tightly fitted with the outer sides of the trimming wheel 22 and the grinding wheel 23 respectively.

After that, the fixing ring 24 can be directly twisted to remove it, and the trimming wheel 22 and the grinding wheel 23 can be replaced and maintained.
