Film supply mechanism of bale wrapping machine

Abstract

The invention relates to the technical field of agricultural machinery operation, in particular to a film supply mechanism of a bale wrapping machine. The film supply mechanism comprises a support rod, a guide sleeve and a clamping device and is characterized in that the support rod is vertically mounted on the bale wrapping machine, the guide sleeve sleeves the support rod, the clamping device isused for clamping a film winding roller and comprises a support platform, a guide mechanism and a pull mechanism, the support platform can support the film winding roller, the film winding roller canrotate on the support platform, the guide mechanism can constantly attach to the surface of the film winding roller, the pull mechanism is used for changing the distance between the guide mechanism and the support platform, the support platform is horizontally fixedly mounted at the bottom of the guide sleeve, the guide mechanism is in running fit with the guide sleeve through a hinge rack, the pull mechanism is arranged on the hinge rack, and the guide mechanism comprises a plurality of vertical guide rollers which are in running fit with the hinge rack. The film supply mechanism has the advantages that film folding during film discharge can be avoided by the guide mechanism, film winding roller loosening can be prevented, the film winding roller can be prevented from getting stuck, andhand pinching or excessively large pulling strength can be avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery operations, in particular to a film supply mechanism of a bale wrapping machine. Background technique [0002] The film supply mechanism in the existing bale wrapping machine is generally only the rotating shaft of a single film supply roller, and there are also several guide shafts near the rotating shaft, but all the guide shafts rotate independently, and all the guide shafts The rotation speeds of each other are different, which may cause the film to fold, so that when the bale is wrapped, too much film is used, resulting in waste. The film roller is loose, causing the film to accumulate in the film supply mechanism, which then causes the film supply mechanism to be stuck. Contents of the invention [0003] The object of the present invention is to provide a film supply mechanism of a bale wrapping machine to solve the problems raised in the above-mentioned background technolo...

[0002] The film supply mechanism in the existing bale wrapping machine is generally only the rotating shaft of a single film supply roller, and there are also several guide shafts arranged near the rotating shaft, but all the guide shafts rotate independently, and all the guide shafts The speed of rotation is different from each other, which may cause the film to fold, so that when the bale is wrapped, too much film is used, resulting in waste. The film roller is loose, causing the film to accumulate in the film supply mechanism, which then causes the film supply mechanism to be stuck
