Background

The plastic flat filament is a basic material of woven fabrics such as netting gear and the like, the production process of the plastic flat filament is complex, and generally comprises the working procedures of film forming, film slitting, flat filament drafting and shaping, flat filament winding or conveying to a warp knitting machine and the like. The film slitting and flat filament drawing and shaping work is usually completed by a filament cutting machine, and the function of the filament cutting machine is to firstly flatten and extrude the film, then utilize a blade on a knife rest to cut the film into a plurality of equally divided strip flat filaments, and then extrude, heat and extrude, stretch and shape the strip flat filaments to form a regular strip of plastic flat filaments.

The heating process of the existing cut tobacco cutting machine is mainly realized by an electric heating drying plate or a drying oven heated by a heat-conducting medium, one surface of the drying plate or the drying oven is provided with an outwardly-bulged cambered surface model, and the cut strip-shaped flat tobacco is tightly attached to the cambered surface of the drying plate or the drying oven to move, so that the strip-shaped flat tobacco is uniformly heated, and the heated strip-shaped flat tobacco is pulled and extruded to form plastic flat tobacco with proper width and thickness and high mechanical strength.

Because the faults such as broken filaments occur occasionally in production, when the machine stops running, the long-strip flat filaments on the drying plate or the drying oven do not move forward any more, but the drying plate or the drying oven still works, and even if the drying plate or the drying oven do not heat any more, the residual heat of the drying plate or the drying oven still can cause the long-strip flat filaments on the drying plate or the drying oven to heat for a long time, the flat filaments are deformed or broken, and the quality of the flat filaments and the normal running of the machine are affected.

In view of the above problems, chinese patent No. ZL201621300775.1 discloses "an anti-scald device capable of separating a plastic flat wire from a heating device", which comprises a drawing heating mechanism and an elevating mechanism, wherein the elevating mechanism is capable of driving the drawing heating mechanism to descend to be separated from the plastic flat wire when the machine is in a breakdown shutdown; and a wire supporting mechanism for supporting the plastic flat wires when the machine is stopped due to faults is also arranged in front of and/or behind the drafting and heating mechanism. This patent application can separate flat filament and heating mechanism when the machine is shut down, has solved the problem that the flat filament is scalded badly. However, during the descending process of the drawing heating mechanism, the loose flat filament is also descended, so that the descending stroke of the oven is required to be larger. For this reason, the preferred design is to cooperate with the wire-supporting mechanism to support the flat wire upward, which again results in a more complex overall structure, which is not conducive to use in a compact wire-cutting machine.
