Description

A kind of plaster line film covering device

Technical field

The invention belongs to plaster line processing and packing equipment technical field, and in particular to a kind of special film covering device of plaster line.

Background technology

Plaster line is one kind of plastering, is mainly included：Linea angulata, horizontal line, camber line etc., raw material are land plaster, by with one The water mixing of certainty ratio pours into mould and adds fiber increase toughness；Can be with various decorative patterns, it is mostly installed at ceiling and wall The angle of wall, inside can also lay water power pipeline, have the advantages that cheap；Simultaneously, it may have fire prevention, moistureproof, insulation, Sound insulation, heat-insulated function, decorative effect are also very attractive in appearance.

At present, plaster line meeting package after shaping is made carries out packed and transported, is influenceed by plaster line self character, Need that the outer layer of plaster line first is applied into layer of plastic film, you can to prevent from making dirty pollution, moreover it is possible to play good protection against the tide Barrier is attractive in appearance, is easy to the effect carried；Due to the longer dimension of plaster line own form, the process of overlay film is all that tubular is thin Membrane cover is cut off in the outside of plaster line, then by cutting knife to film, is eventually passed heat sealing machine and is carried out sealing packaging, this Process will could substantially be completed by three process；Traditional mode of operation is that manually plaster line is placed on fixed mesa And its one end is lifted one end is entangled with film, then the other end is lifted again, film is gradually spread out and entangled；Then cutting knife is used After film is cut off, the plaster line for packaging film is lifted to another sealing table top, by manually by the two ends flattening heat of film After sealing machine sealing, then stored by artificial carry away.

This operating process needs several Collaboration operations, and not only labour cost is high, and needs constantly to lift carrying, Hand labor intensity is big, inefficiency, fragile product；Secondly, the mode of artificial set film is easy to film occur to scratch Phenomenon, because manually manner of packing otherness is big, and the harder corner angle of plaster line quality are substantially, during suit, Corner angle are easy to puncture film and broken, and influence package quality, also easily scratch the hand of operating personnel；Again, it is of the prior art There is hardness, intensity and the inadequate defect of toughness in cutting knife, easily cause and cut the problems such as thorough and cutting knife is not broken mostly.

Accordingly, it would be desirable to a kind of pipeline system equipment that can automatically pack, cut off, seal and transport change at present fall behind Working method, reduces the labor intensity of workman, improves the competitiveness of product in market.
