Description

Technical Field

[0001] The utility model relates to the technical field of highway film laying, in particular to an anti-wrinkle type highway engineering film laying device. Background Art

[0002] Some road surfaces are made of cement. Cement requires appropriate moisture to solidify and react with moisture to continuously increase the hardness of the concrete. After the highway is poured, a plastic film needs to be laid on the surface of the highway to prevent moisture from evaporating too quickly, which will lead to the solidification of the concrete, cracking, peeling, etc., affecting the strength of the concrete.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: in order to avoid the labor cost of manually rotating the winding roller to release the film, the existing anti-wrinkle type highway engineering film laying device mostly chooses motor-driven method to release the material. If the motor is turned off in advance before stopping the moving device, the inertia of the film recovery device will pull the film, causing varying degrees of damage. Most of the time, the motor is turned off with a lag, but there will be a situation where too much film is released, resulting in unnecessary waste of film use and a high usage amount, which urgently needs to be improved. Therefore, we propose an anti-wrinkle type highway engineering film laying device. Utility Model Content
