Description

Technical Field

[0001] The utility model relates to the technical field of processing and producing sealing strips, in particular to a traceless traction device for sealing strips of plastic profiles. Background Art

[0002] The main function of door and window sealing strips is sealing. Only with good sealing performance can they play the role of waterproof and dustproof, soundproof and heat-insulating, warm and antifreeze, thereby achieving energy-saving effects. After the door and window sealing strips are processed and produced, they usually need to be transported and cut with the help of conveying equipment. At present, the sealing strips are mainly transported by upper and lower conveyor belts. The sealing strips are mainly transported by the clamping force between the two conveyor belts. However, due to the structural reasons of the conveyor belts themselves, the conveyor belts are composed of a piece of pressing plate. In the process of using the conveyor belts to transport the sealing strips, a concave point will be pressed on the sealing strips, that is, it will cause indentations on the sealing strips, which will affect the quality of the sealing strips and the subsequent use effect.
