The utility model is further provided with: and the compaction roller is provided with a pushing mechanism for pushing the compaction roller to the tensioning roller.
The advantages according to this solution are at least: the pushing mechanism can push the compaction roller to the tensioning roller, so that the plastic film can be conveniently penetrated on one hand, the clamping force can be controlled on the other hand, and the clamping state is ensured.
The utility model is further provided with: the compaction roller is a flexible roller having deformability.
The advantages according to this solution are at least: the rubber roller has slight deformability, has larger friction force compared with the common metal roller, can clamp the plastic film, and can not cause the problem of slipping.
The utility model is further provided with: the pushing mechanism comprises a pushing cylinder which is fixedly arranged, an installing frame is arranged on an output shaft of the pushing cylinder, and the compacting roller is rotationally connected to the installing frame.
In summary, the present utility model has at least the following advantages:
1. by arranging the compaction roller, the plastic film passes through the tension roller and the compaction roller and can be clamped between the tension roller and the compaction roller, so that the edge ironing position can be clamped and limited in the edge ironing process of the plastic film, and the problem that the film on the inner side is wrinkled due to tension change is avoided;
2. through setting up pushing equipment, pushing equipment can push away compaction roller to the tensioning roller, makes things convenient for plastic film's wearing to establish on the one hand, on the other hand can control the clamping strength, guarantees the clamping state.

Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The utility model provides an edge ironing mechanism, includes the tensioning roller 3 that is fixed in between wind-up roll 1 and the unreeling roller 2, and wherein, wind-up roll 1 and unreeling roller 2 are installed respectively at the both ends of frame 8, and tensioning roller 3 installs the position between the both ends of frame 8.
The outside of at least one end of tensioning roller 3 is fixed with heat-generating body 6, and the top of heat-generating body 6 is fixed with rotatable cone pulley 7, and plastic film 9 can pass in the clearance between cone pulley 7 and heat-generating body 6 to tighten on tensioning roller 3. In the winding and unwinding process, the plastic film 9 is ironed into a side strip by the cone pulley 7 and the heating body 6.
A compacting roller 4 is rotatably connected above the tensioning roller 3, and a plastic film 9 passes through between the tensioning roller 3 and the compacting roller 4. The compacting roller 4 is a flexible roller with deformation capability, such as a rubber roller, a silicone roller, or the like, which is capable of ensuring that the entire roller bottom is in contact with the plastic film 9. In the winding and unwinding process, the inner side of the plastic film 9 can be clamped and limited by the compacting roller 4 and the tensioning roller 3, so that the problem that the inner side of the plastic film 9 is wrinkled due to tension change is avoided.
