Automatic roll changing device for mulching film winding machine

Abstract

The invention discloses an automatic roll changing device for a mulching film winding machine. The automatic roll changing device is arranged on a frame of the mulching film winding machine; the mulching film winding machine comprises winding roller sets respectively consisting of two matched winding rollers; each winding roller set is provided with a power device for driving the winding roller set to roll, and is provided with a mulching film winding drum which rotates together with the winding roller set and used for winding a mulching film; at least two winding roller sets are arranged; and the automatic roll changing device comprises a cutoff mechanism used for cutting off the mulching film, and a film winding mechanism used for winding the cut mulching film to the mulching film winding drum, wherein the cutoff mechanism is arranged on the frame of the mulching film winding machine, and the film winding mechanism is arranged below the cutoff mechanism. The automatic roll changing device realizes the automatic cutoff and roll changing of the mulching film, solves the technical problem which cannot be solved by technicians in the field for a long time, is structurally provided with the special cutoff mechanism and the film winding mechanism, has substantial characteristics, and has obviously improved effect.

Description

technical field [0001] The invention relates to the technical field of film winders, in particular to an automatic roll changing device of a film roll changer. Background technique [0002] Mulch film, especially light-weight mulch film, needs to use a mulch film winding machine during production. The traditional mulch film winding machine generally includes a winding roller set composed of two cooperating winding rollers, and the winding roller set is placed The mulch reel, the mulch is pressed between the rewinding roller group and the mulch reel; when working, the rewinding roller rolls under the action of the driving device, driving the mulch reel to roll on its surface, and the mulch will be wrapped around the mulch reel superior. There are generally two groups of winding rollers, which alternately carry out the winding work of the plastic film. When a plastic film reel is wound with a marked amount of plastic film, it is necessary to change the roll. [0003] The rol...

AI Technical Summary

Problems solved by technology

Since the cutting and roll changing of the mulch film has been done manually for a long time, it has affected the continuity of the mulch film production and reduced the production efficiency. The film cutting device uses a blade to quickly cut the film, but still requires the staff to manually operate the cutting device on time to cut the film

[0004] From the above, it can be seen that the technology of film winding machine is not mature in changing rolls, and has the following obvious defects: 1. The staff needs to manually operate the cutting device, and the degree of automation is not high, which greatly affects the amount of film winding. 2. It is not possible to change the roll automatically. After the film is cut off, the film needs to be manually wound on the film reel to continue winding, which destroys the continuity of film production and reduces the productivity
