Film cutting mechanism for straw bale film wrapping machine and film cutting method thereof

Abstract

The invention relates to the technical field of agricultural machinery operation, in particular to a film cutting mechanism for a straw bale film wrapping machine and a film cutting method thereof. The film cutting mechanism comprises a film clamping mechanism, a cutting mechanism and a driving mechanism for driving the film clamping mechanism to open and close; the film clamping mechanism comprises a main clamping plate and an auxiliary clamping plate, the horizontal cross section of the main clamping plate is in an inverted-T shape, and the horizontal cross section of the auxiliary clampingplate is of a U-shaped structure; the cutting mechanism comprises a vertical electric cylinder and a cutting part; the middle of the auxiliary clamping plate is provided with a vertical strip-shaped hole; and the driving mechanism comprises an X-shaped rotary frame, and the main clamping plate and the auxiliary clamping plate are fixed to the two ends of the X-shaped rotary frame correspondingly.According to the film cutting mechanism for the straw bale film wrapping machine and the film cutting method thereof, it can be achieved that the cutoff position after plastic film wrapping is automatically cut, and the cutoff efficiency and the straw bale wrapping efficiency are improved; an unwound plastic film can be cut, the situation that the ends of the cut plastic film adhere to each otheris avoided, through the film clamping mechanism, plastic film wasting caused by cutting line deflection is avoided, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery operations, in particular to a film cutting mechanism of a bale wrapping machine and a film cutting method thereof. Background technique [0002] The existing bale wrapping machine wraps the plastic film around the bale. After the wrapping is completed, the plastic film needs to be cut off. In the existing way of cutting the plastic film, someone manually holds the cutting tool to press the cut-off position of the plastic film into a strand, and then cuts the plastic film into one strand with a cutting tool. The tool cuts off the truncation position of the plastic film, the cutting efficiency is low, and the bale winding efficiency is reduced. Because the plastic film has a certain viscosity, the truncation position sticks together, resulting in a certain waste. Contents of the invention [0003] The object of the present invention is to provide a film cutting mechanism and a film...
