Referring to FIG. 5 , the outer wall of the conveying roller 3 is surrounded by a thin metal profile 7 . The conveying roller 3 is located at the inlet end of the cutting platform 101 . One end of the sheet metal profile 7 is located in the leveling assembly 2 . An induction frame 4 is arranged between the conveying roller 3 and the leveling assembly 2 . The thin metal profile 7 is set through the induction frame body 4 . A thin metal profile sensor 5 is arranged on the upper side of the induction frame body 4 . The conveying roller 3 is provided with a driving member 6 for driving the conveying roller 3 to rotate. The driving member 6 can be a motor, etc., which is a very common prior art, and will not be described in detail here. When the leveling assembly 2 transports the metal sheet profile 7 forward, the metal sheet profile 7 is straightened and gradually lifted up. When the metal sheet profile 7 touches the metal sheet profile sensor 5, the metal sheet profile sensor 5 sends a signal to the driver 6. The driving member 6 drives the conveying roller 3 to rotate to release a section of the metal sheet profile 7 wound on it.

A numerically controlled control platform 8 is provided outside the cutting platform 101 . The operator inputs the relevant index to the numerical control control platform 8 to make the laser cutting head 104 cut the metal sheet profile 7 into the required size and shape. For those skilled in the art, this numerical control command operation mode is a very existing technology, which has been applied very maturely and widely in this field, and will not be described too much here.

Because laser cutting is to use laser to cut, the cut metal sheet profile 7 will still have high heat to gather there after cutting. It is easier for the sheet to dissipate heat after cutting, so that the heat will not accumulate there and cause damage to the sheet metal and transmission components.

However, since the metal sheet profile 7 needs to be suspended in the air, the frictional force between the metal sheet profile 7 and the protruding portion 108 is relatively small. And the friction force between the sheet metal profile 7 and the protruding portion 108 is changing all the time (the contact area between the sheet metal profile 7 and the protruding portion 108 is large before the cutting, and the friction force between the two is large, and the sheet metal profile 7 After cutting, the contact area between the protruding part 108 is small, and the friction force between the two is small) If the metal sheet profile 7 is only transported by the conveying assembly, after the metal sheet profile 7 is cut, the friction force between the two is too small. The conveying component cannot transport the metal sheet profile 7 to the front end of the cutting platform 101 (there is always slipping phenomenon), so a leveling component 2 is arranged at the front end of the cutting platform 101 . In addition to leveling the thin metal profile 7 , the leveling component 2 also plays a role in transporting the thin metal profile 7 to the front end of the cutting platform 101 .

Is it feasible if there is no conveying component installed in the cutting platform 101 . The answer is not feasible, because the metal sheet is formed after the metal sheet profile 7 is cut, because the metal sheet profile 7 and the thickness of the metal sheet are very low, when the leveling assembly 2 transports the metal sheet profile 7 and moves, the metal sheet profile 7 does not The metal flakes will be pushed away from the cutting platform 101. In actual production, the metal flakes will remain still, and the metal flake profile 7 and the metal flakes will be dislocated and piled up. According to repeated tests in actual production applications, it is found that the leveling assembly 2 must be installed at the end of the cutting platform 101 to transport the sheet metal profile 7 and the conveying assembly inside the cutting platform 101 to transport the sheet metal is the solution to avoid the phenomenon mentioned above.

However, with such a design, when the operating speeds of the transmission assembly and the leveling assembly 2 are different, new problems are found in actual production. When the conveying speed of the leveling assembly 2 was greater than the conveying speed of the conveying assembly, after the metal sheet profile 7 moved a certain distance on the cutting platform 101, the frictional force of the metal sheet profile 7 on the cutting platform 101 increased (as the metal sheet profile 7 and more and more Many protrusions 108 generate friction), due to the increase of friction, the front end of the sheet metal profile 7 cannot move relative to the conveying assembly, and the leveling assembly 2 is still transporting the sheet metal profile 7 into the cutting platform 101, Thereby the metal sheet profile 7 appears upward bending phenomenon; As the metal sheet profile 7 and more and more protruding parts 108 generate friction), due to the increase of friction force, the metal sheet profile 7 and the transmission assembly produce relative motion, and the friction force becomes a forward pulling force, The thin metal profile 7 has good ductility, poor internal stress, and is easily stretched and deformed under the action of friction.

Therefore, in this embodiment, an additional supporting point 109 is provided on the upper end of the protruding portion 108 . The support point 109 has only point-to-point friction with the metal sheet profile 7, which significantly reduces the friction between the transmission component and the metal sheet profile 7. When the delivery speed of the leveling component 2 is greater than the delivery speed of the transmission component, the metal sheet profile 7 will overcome The frictional force between it and the support point 109 moves forward, and the contact part of the metal sheet profile 7 and the support point 109 will not be unable to move, causing bending phenomenon during the transportation of the metal sheet profile 7; When the component is transported at a high speed, the frictional force generated by the relative sliding between the metal sheet profile 7 and the support point 109 will not cause the metal sheet profile 7 to be stretched and deformed.

The above descriptions are only preferred embodiments of the present invention, and it should be understood that the present invention is not limited to the forms disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and Modifications can be made within the scope of the ideas described herein, by virtue of the above teachings or skill or knowledge in the relevant art.
