Description

Technical Field

[0001] The invention relates to the technical field of synthetic leather processing, and in particular to a bio-based solvent-free synthetic leather production device and method. Background Art

[0002] Bio-based solvent-free synthetic leather is an environmentally friendly synthetic leather made from biomass using a solvent-free process. It has the characteristics of wear resistance, environmental protection, and high performance. During the processing and production of bio-based solvent-free synthetic leather, slitting equipment is required to slit the bio-based solvent-free synthetic leather to meet the production needs of synthetic leather of different sizes. During the slitting process, the slitting blades of existing bio-based solvent-free synthetic leather production equipment will wear out over time as a consumable part, affecting the cutting effect, especially when cutting thick synthetic leather, which can easily lead to uneven cutting lines. However, since the blades are usually fixed to the equipment in large quantities by bolts, the replacement process is cumbersome and time-consuming and labor-intensive. Summary of the invention

[0003] The disclosed embodiments relate to a bio-based solvent-free synthetic leather production device and method.

At this time, the slitting carriage will automatically separate the docking head from the winding roller with the cooperation of related structures. This action is convenient for easily removing the winding roller that is full of synthetic leather and for installing a new winding roller. When the slitting carriage is lowered together with the slitting tool to prepare for slitting operation, the docking head will automatically reconnect with the winding roller with the cooperation of related structures, thereby ensuring that motor A can drive the winding roller to smoothly carry out the winding and slitting of synthetic leather.
