During the operation of the PP plastic hollow board production line, we need to constantly pay attention to the pulling effect of the equipment. Once any abnormalities are found in the pulling plate, the production line needs to be adjusted to avoid affecting subsequent production.
So what are the situations during the operation of the PP plastic hollow board production line that belong to abnormal pulling, and what are the reasons for this situation? Today, the editor will briefly explain this issue to everyone.
Exception 1: Deformation of the pulling plate
During the pulling process of the equipment, the board may deform due to reasons such as excessive extrusion speed or uneven stretching. Once this happens, it will affect the flatness and appearance quality of the final product. Therefore, operators must be extra careful when designing the operating speed and stretching speed of the PP plastic hollow board production line.
Exception 2: Uneven pulling plate
During the stretching process of sheet metal, if the sheet metal is affected by factors such as unstable extruder pressure, improper temperature control, or insufficient cooling, it can lead to uneven surface of the sheet metal. Therefore, factors such as extruder pressure, temperature, and cooling are also areas that operators should pay close attention to.
Exception 3: There are traces on the pull plate
During the pulling process, due to uneven stretching force or inaccurate cutting, traces may appear on the surface of the board, which are also considered unqualified products.
Exception 4: Uneven edges of the pull plate
In the final cutting process, if the cutting tool does not cut accurately or the cutting speed is too fast, it can also cause abnormal situations of uneven edges on the board, which can affect the appearance and quality of the edges of the board.
The above are four common abnormal situations in the operation of PP plastic hollow board production lines. It can be seen that each abnormal situation is caused by incorrect operation in one or two places. Therefore, when setting the operating parameters of the production line, operators must conduct multiple tests based on the characteristics of the entire production line to ensure that the equipment reaches the best operating effect before being put into use, so as to avoid any abnormal situation affecting subsequent production.
