Film packaging system of cotton packaging machine

Abstract

The invention discloses a film packaging system of a cotton packaging machine. The film packaging system is used for conveying films to a cotton packaging cavity in a cotton bale forming box, whereinan opening allowing the films to enter is formed in the cotton packaging cavity; and a rotating roller table for driving the cotton packaging cavity to continuously rotate is arranged on the opening.The film packaging system comprises a film roll marked with RFID (Radio Frequency Identification) tags in a segmented mode, a film transferring part, a film feeding part and a film conveying roller used for arranging the film roll in a sleeved manner, wherein the film conveying roller is arranged on the cotton bale forming box and is connected to an electromagnetic clutch; and the electromagneticclutch is electrically connected to an identification sensor which is arranged to be abutted against the film conveying roller; the film feeding part is located under the rotating roller table; the film transferring part is used for driving the films to be conveyed from the film conveying roller to the film feeding part; and the film feeding part is used for accurately feeding the films into the opening. The film packaging system ensures the accuracy of the films entering the opening position, and improves the continuity of cotton bale film packaging.

Description

Technical field: [0001] The invention relates to the technical field of production of cotton packing equipment, in particular to a film packing system of a cotton packing machine. Background technique: [0002] The cotton baler is mainly used to extrude and pack the picked cotton into a circle and wrap the round cotton bales with a film. The degree of automation is high, which greatly improves the efficiency of cotton packaging in cotton planting bases. [0003] At present, the cotton baler mainly includes a cotton bale forming box and a film packaging system. The inside of the cotton bale forming box has a cotton packaging cavity for baling cotton, and the film packaging system is mainly used to transport the film from the film packaging system to the cotton packaging cavity. At the opening position, when the cotton bale inside the cotton baling cavity continues to rotate, the conveyed film is automatically packaged to cover the outside of the cotton bale. However, in the a...

Problems solved by technology

[0003] At present, the cotton baler mainly includes a cotton bale forming box and a film packaging system. The inside of the cotton bale forming box has a cotton packaging cavity for baling cotton, and the film packaging system is mainly used to transport the film from the film packaging system to the cotton packaging cavity. At the opening position, when the cotton bale inside the cotton baling cavity continues to rotate, the conveyed film is automatically packaged to cover the outside of the cotton bale. However, in the actual application of the film baling system, there are mainly the following two problems: 1. Cotton The opening of the packing cavity is generally small, and it is difficult to ensure that the film is accurately transported into the opening, causing the film to wrap around the opening, affecting the film packaging coverage of the cotton bale; 2. After the film enters the cotton packing cavity from the opening, on the one hand, the film After the fracture, sometimes it is necessary to manually adjust the fracture position of the film to ensure the subsequent transmission of the film, which reduces the continuity of the film packaging on the cotton bale.
