Further, the elevating mechanism includes left and right screw rod, pivoted housing, lifting seat and rotating mechanism, and the lifting seat can Being arranged in frame for lifting, is socketed on the jointed shaft of left crank and left connecting rod, the right screw rod on the left of the left screw rod Right side be socketed on right crank and the jointed shaft of right connecting rod, the right side and left side of the left and right screw rod are inserted in pivoted housing simultaneously respectively Coordinate with pivoted housing screw thread, the left and right screw flight is oppositely oriented, the rotating mechanism is located on lifting seat and drives pivoted housing Rotate.
Further, the frame is provided with the spring of support lifting seat.
Beneficial effects of the present invention:
1st, lath cutter of the invention, balance, the stability of dynamic model are strengthened by setting balance leverage, and structure and control are more It is easy;
2nd, lath cutter of the invention, elevating mechanism drives lower knife body to lift by moving horizontally, and lower knife body is lifted more Steadily, equipment overall structure is compacter, occupy little space.
Brief description of the drawings
Fig. 1 is a kind of front view (lower knife body is in bottom position) of lath cutter of the invention;
Fig. 2 is a kind of front view (lower knife body is in tip position) of lath cutter of the invention.
Specific embodiment
For technological means, creation characteristic, reached purpose and effect for making present invention realization are easy to understand, with reference to Specific embodiment, is expanded on further the present invention.
Figure is referred to, the present invention provides a kind of technical scheme:A kind of lath cutter, including frame 10, upper knife body 20, lower knife body 30 and elevating mechanism 40, upper knife body 20 is fixedly installed in frame 10, and frame 10 includes left and right column and the left and right column of connection Bottom girder 101, lower knife body 30 is located at the lower section of upper knife body 20 and can be moved up and down along frame 10, the driving lower knife body 30 of elevating mechanism 40 Move to shear sheet material relative to upper knife body 20.Elevating mechanism 40 can be the mechanisms such as hydraulic cylinder or crank block.
Balance leverage 50 is provided between the bottom girder 101 of lower knife body 30 and frame 10, balance leverage 50 includes left and right crank 501st, 502 and left and right connecting rod 511,512, left and right crank 501,502 is symmetrically set in the both sides of the longitudinal center of lower knife body 30, left, Right connecting rod 511,512 is also symmetrically set in the both sides of longitudinal center, and the lower end of left and right crank 501,502 is hinged with frame 10, Lower end of the upper end of left and right crank 501,502 respectively with left and right connecting rod 511,512 is hinged, the upper end of left and right connecting rod 511,512 It is hinged with lower knife body 30.Left and right connecting rod 511,512 is connected to the both sides at the center of lower knife body 30, when lower knife body 30 is moved up and down, Left and right crank 501,502 swings around it with the jointed shaft 523,524 of bottom girder 101, and left and right connecting rod 511,512 can make lower knife body 30 Both sides are supported makes it keep balance, stationarity when enhancing lower knife body 30 is moved up and down.
Elevating mechanism 40 includes left and right screw rod 401,402, pivoted housing 403, lifting seat 404 and rotating mechanism, lifting seat 404 It is liftable to be arranged on the bottom girder 101 of frame 10, specifically, be provided with chute on bottom girder 101, the bottom of lifting seat 404 and cunning The vertically slidable cooperation of groove, the left side of left screw rod 401 is socketed on the jointed shaft 521 of left crank 501 and left connecting rod 511, right screw rod 402 right side is socketed on the jointed shaft 522 of right crank 502 and right connecting rod 512, the right side and left side of left and right screw rod 401,402 Coordinate in insertion pivoted housing 403 and with the screw thread of pivoted housing 403 respectively, the thread rotary orientation of left and right screw rod 401,402 is conversely, rotating mechanism On lifting seat 404 and pivoted housing 403 is driven to rotate.Rotating mechanism such as motor etc. drives pivoted housing 403 by gear or belt etc. Rotate, pivoted housing 403 is rotated will drive left and right screw rod 401 simultaneously towards or away from movement, and left and right screw rod is towards or away from shifting While dynamic, left and right crank 501,502 will be driven towards or away from swing by jointed shaft 521,522, so as to realize lower knife body 30 Lifting, left and right screw rod 401,402 closer or far from while, due to jointed shaft 521, the change of 522 positions, left and right screw rod 401 and pivoted housing 403 also will lifting, the lifting of left and right screw rod 401 and pivoted housing 403 is realized by lifting seat 404.Elevating mechanism 40 integral levels are set, and move horizontally to realize the lifting of lower knife body 30 by left and right screw rod, and equipment overall structure is compact, left, The horizontal applied force of right screw rod is acted on lower knife body by left and right connecting rod, and lower knife body lifting is more steady.
