Fig. 3 is structure chart of the present invention;

Wherein, 1 discharging frame, 2 intermittent feeding devices, 3 rolling and cutting mechanisms, 4 rolling cuts wheels, the upper rolling cut wheel of 4a, under 4b, rolling cut is taken turns, 5 cutterheads, 6 pads, 7 sliding-rail grooves, 8 carving knives, 9 blades, cutting roller on 10,11 times cutting rollers.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

According to Fig. 1-2, there is muscle net production line, comprise discharging frame 1, rewinding frame, between discharging frame 1 and rewinding frame, be provided with intermittent feeding device 2, the roll-turning extension fixture of plumbous net (be rolling and cutting mechanism and drawing mechanism, material transports at lead), flattening mechanism, cutting device on the net.

Specifically comprise as lower component: (1) double end discharging frame: self-powered double end discharging frame, can realize autonomous blowing. Bilateral blowing, can realize and realize for a long time continuous production. Between double end discharging frame and rolling cut main frame, intermittent feeding device is set, can automatically whether controls blowing. Too fast when blowing, occur overstocking, material is encountered lower inductive rod, and lower sensor senses material, and then makes motor stalling; Along with constantly advancing of material, material overstocks and reduces, and material is encountered upper inductive rod, and upper sensor senses material also and then makes motor start to rotate, to carry out new round blowing.

(2) rolling and cutting mechanism: on the running roller of rolling and cutting mechanism 3, chopper is one chip cutter, can produce different products by difform cutterhead 5 combinations. Remaining frame and axle share. Between cutterhead 5 and cutterhead 5, be added with pad 6, pad 6 does not carry out rolling cut to raw material. For different net sheets, suitable shimming 6 is isolated. After completing, rolling cut enters stretching device. Pull open by the raw material that it is good that the expansion of stretching arm allows rolling cut, form mesh. Stretching arm is adjustable, can regulate the size of mesh. Preferably, along two diagonals (or approaching diagonal) the horizontal tractive simultaneously of the net sheet after rolling cut, realize expansion.

The course of work is: galvanized sheet enters through double end discharging frame 1 between two rolling cut wheels 4 of rolling and cutting mechanism 3, at two rolling cut wheel (4a, the intersection point of cutterhead 5 laps 4b) is the effect that cutterhead 5 pad 6 places corresponding with another rolling cut wheel 4b of a rolling cut wheel 4a are subject to shearing force, galvanized sheet generation plastic deformation, along with relatively rotating of rolling cut wheel 4, the tangential component that galvanized sheet is produced impels galvanized sheet reach, cutterhead 5 produces larger axial force to galvanized sheet, the degree of depth of clamp-oning galvanized sheet strengthens, last axial thrust load exceedes the armor plate strength limit and brittle deformation occurs and forms breach.

(3) leveling structure: the net sheet after rolling cut stretches out, by 13 groups of roll-ins flat (upper six times seven), flattens net sheet.

(4) cutting device: have muscle net cutting device, comprise cutting roller 10 and lower cutting roller 11, it is characterized in that: also comprise the axial sliding-rail groove 7 that is arranged at respectively cutting roller 10 and lower cutting roller 11, the some carving knives 8 of the interior installation of sliding-rail groove 7, described carving knife 8 moves (being that carving knife 8 slides in groove) along sliding-rail groove 7, the carving knife that is positioned at cutting roller 10 cooperatively interacts with the carving knife that is positioned at lower cutting roller 11, forms a component cutting knife.
