Abstract: Disclosed is a flattening device, comprising: a rack; a material-pressing component, which is provided on the rack and has a material-pressing part; a material-guiding component, which is provided on the rack and has a material-guiding part corresponding to the material-pressing part, the material-pressing part and the material-guiding part being configured to be able to bear against two sides of a sheet material respectively, so as to form a flattening channel between the material-guiding part and the material-pressing part; and an adjusting component, which drives at least one of the material-pressing component and the material-guiding component to move, so as to adjust the distance between the material-pressing part and the material-guiding part. Further disclosed are a material-conveying apparatus including the flattening device and a sheet material processing system comprising the material-conveying apparatus.

Abstract: The steel strapping machine without using joint currently available from the market has three shortcomings. Firstly, packages cannot be strapped tightly. Secondly, a steel strap may get caught on a lower mold when the lower mold is taken out from underside of the steel strap. Thirdly, the strapping machine is not available for small packages. To overcome the shortcomings of the prior arts, the present disclosure proposes a separatable lower mold of the steel strapping machine without using a joint, which is formed as two parts being able to be closed together or separated from each other. The separatable lower mold has advantages that packages can be strapped tightly, the steel strap will not get caught on the lower mold when the lower mold is taken out from the underside of the steel strap and it is possible for the strapping machine to strap small packages.
