[0010] According to the above technical solution, the adjusting clamping block includes a block body, a movable plate, a rotating plate, a locker, a second motor, a third cylinder, a movable rod, a connecting plate and a rubber pad.

During the cutting process of the door and window profiles, the cut debris may splash, causing the contact plate to contact the debris and dust, affecting the fixing effect of the door and window profiles. A vibration motor is arranged inside the cylinder, and the vibration of the contact plate by the vibration of the vibration motor causes the profile debris to be vibrated off the contact plate, thereby reducing the work of manual cleaning and extending the service life of the contact plate.

[0015] According to the above technical solution, a rubber protrusion is provided at one end of the movable plate, and the rubber protrusion faces one end of the block. The movable plate is driven to move by the third cylinder, so that the position of the lateral fixed block can be adjusted.

The first cylinder and the adjusting and fixing mechanism are offset and placed to ensure the cross fixation of the door and window profiles, which can effectively improve the fixing effect of the door and window processing, and at the same time will not affect the rotation of the lateral fixing block, thereby ensuring the fixing effect of the special-shaped door and window profiles.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] 1. The present invention can effectively fix the door and window profiles by moving the clamping block and adjusting the fixing mechanism, thereby ensuring that the door and window remain stable during the processing, ensuring that the cutting position is accurate, and the cutting effect is good.

[0020] 2. The present invention drives the connecting plate to move by the third cylinder, which can drive the movable plate to adjust its position. Cooperating with the second motor to drive the rotating plate to rotate, the position and angle of the lateral fixing block can be adjusted, so as to facilitate the lateral fixation of special-shaped door and window profiles, ensure the fixing effect of the door and window profiles, and prevent the double fixation of the side top from being poor due to the special-shaped profiles, thereby causing the problem of cutting offset, affecting the subsequent processing of the door and window profiles.

[0021] 3. The present invention uses the vibration of the contact plate by the vibration motor to vibrate the profile debris off the contact plate, thereby reducing the manual cleaning work and extending the service life of the contact plate. The third cylinder drives the movable plate to move in the opposite direction, allowing the rubber protrusion to collide with the inside of the block. The vibration generated by the collision can vibrate the profile debris stuck at the bottom off. Similar to the contact plate, it can reduce the manual cleaning work and extend the service life of the contact plate.

[0022] 4.

Similarly, the third cylinder 225 drives the movable plate 221 to move in the opposite direction, so that the rubber protrusion 2211 can collide with the inside of the block 220. The vibration generated by the collision can vibrate the adhered profile debris at the bottom of 208 off. Similar to the contact plate 251, the work of manual cleaning can be reduced and the service life of the contact plate 251 can be extended.

[0043] In summary, when the device is in use, the processed door and window profile is placed on the rotating drum 202, and the expansion table 5 is used to ensure the stability of the placement. The first motor 203 drives the rotating drum 202 to rotate, and the position of the profile is adjusted according to the set system. Then the first cylinder 204 drives the mobile clamping block 205 to move, contact one end of the profile, and cooperate with the positioning fixing plate 206 to fix the profile. Then the second cylinder 212 drives the lifting rod 213 to descend, so that the rubber pad 228 fixes the top of the profile. For wide profiles, the third cylinder 225 drives the mobile clamping block 205 to move. The plate 221 moves to move the lateral fixing block 215 to the other end of the top of the wide profile to ensure the fixing effect for the wide profile. For special-shaped profiles, after moving the movable plate 221 to a suitable position, the second motor 224 drives the rotating plate 222 to rotate and adjusts the angle of the lateral fixing block 215. Then the fourth cylinder 231 drives the lower pressure plate 233 to fix the profile. In combination with the fixation of the movable clamping block 205 and the rubber pad 228, the three-point fixation ensures the fixing effect for special-shaped door and window profiles. The profile is then cut by the cutting blade 4 to ensure accurate and stable processing.
