Go up universal attaching parts and be enclosed within outside the pull bar, described spacing structure is to be enclosed within the outer spacer of pull bar.
Because adopt the technical solution of the utility model, the utility model can be finished send-back, fastening belt, and is simple in structure, reduce fault rate, it is effective to pack; And, can realize that the limit moves back the action of band edge tension, when the strap tension puts in place, can rely on the electric current of motor to change, make control setup in real time, accurately obtain signal, other device of accurately controlling compress carries out follow-up cutting band, scald and step such as glue.
Description of drawings
Fig. 1 is the scheme drawing from an angle observation of embodiment provided by the utility model.
Fig. 2 is the scheme drawing from another angle observation of embodiment provided by the utility model.
Fig. 3 is the structure exploded view of embodiment provided by the utility model.
The specific embodiment
With reference to accompanying drawing.The utility model comprises driving roller 3, first return idler 1, second return idler 2, the forward (FWD) direction of pressing strap, and first return idler 1 is in the downstream of second return idler 2;
Circumferencial direction along driving roller 3 between described first return idler 1 and second return idler 2 is provided with strap guiding mechanism 12, such as gib block, orienting lug etc.As shown in the figure, when described driving roller 3 during near the right side of compresses, the have the initiative lower right side of roller 3 of described second return idler 2, the have the initiative upper right side of roller 3 of described first return idler 1, the position of second return idler 2 just is in strap and puts on next position, the area that makes strap wrap on the driving roller 3 is realized maximization, utilizes friction force to make belt more submissive, can improve the packing quality and reduce the packing fault.
Described cam 4 is installed on the movement main shaft 50 of compress, drives rotation by core motor through speed reduction gearing.
Described cam 4 is controlled these actions that described second return idler 2 leans against on the driving roller 3 and leaves driving roller 3 by the oscillation system that a cover contains retracing spring 61 and regulating spring 62.
Described oscillation system comprises first swing arm 63, and described first swing arm 63 is provided with the roller 64 that cooperates with cam; Described first swing arm 63 is passed through down, and universal connecting components 65 is connected with pull bar 66, be with the described regulating spring of being regulated by pull bar upper cap nut 67 62 on the described pull bar 66, pull bar 66 acts on universal attaching parts 68 by regulating spring 62, and regulating spring 62 can play buffer action can also regulate strap encircling force size.
