The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As Figure 1-3, guillotine shut-off mechanism of the present utility model is by stationary knife 7, moving knife 9 and drive moving knife 9 reciprocating reciprocating apparatuses, for providing the power set of power, reciprocating apparatus forms, reciprocating apparatus is by slide plate 3, two operating slide guideway rails that are set up in parallel 12, driving slide plate 3 forms along operating slide guideway rail 12 reciprocating cams 10, stationary knife 7 is fixedly installed on the upper end of mainboard 6, two operating slide guideway rails 12 are separately positioned on the both sides of mainboard 6, and by being fixedly installed on the mainboard 6, the guide rail bearing 5 at following two ends is fixed on the mainboard 6, at the two ends of every operating slide guideway rail 12 linear axis is set respectively and holds 1, four linear bearings 1 be fixedly installed on respectively slide plate 3 on, following two ends, be provided with rectangular cam hole 13 in the middle part of slide plate, the length A of rectangle cam hole 13 is less than its width B, be outside equipped with camshaft bearing 2 at cam 10, and the external diameter of camshaft bearing 2 equals the width B of slot, cam and camshaft bearing are arranged in the cam hole 13,2 tight fits of cam hole 13 and camshaft bearing, stepper motor 11 is fixedly installed on the mainboard 6, step motor shaft passes the motor axis hole 14 that is provided with on the mainboard 6 and is connected with cam 10, fixedly install two bare headed bolts 8 that have the shaft shoulder 15 in the upper end of slide plate 3, shaven head bolt 8 is fixedlyed connected with slide plate 3 by its end of thread, other end suit compression spring 4, moving knife 9 is arranged on two bare headed bolts 8 by two through holes that are provided with on it, compression spring 4 is positioned at 9 of the shaft shoulder and moving knife, mainboard 6 fixedly install stationary knife 7 with corresponding position, moving knife position, moving knife 9 is fitted on the stationary knife 7 under compression spring pressure effect.In order to improve cut-out efficient, moving knife is in the setting that tilts of from top to bottom direction, like this, stationary knife contacts with the band metal wire that confluxes that desire is cut off successively, the metal wire of cut off arranging successively can improve and cut off efficient and easily cut off metal wire, also can be stationary knife in the setting that tilts of from top to bottom direction.
Certainly, cam hole also can be elliptical aperture or other not isometrical hole, as long as on the reciprocating direction of slide plate, the inner hole wall of cam hole contacts cooperation with the external diameter of camshaft bearing, and cam hole inwall and camshaft bearing matched in clearance get final product in the other direction.
During work, step motor shaft rotates, driving cam 10 rotates, because the outer camshaft bearings that are provided with 2 of cam 10 and cam hole 13 are tight fits and be matched in clearance at length direction at width, driving slide plate 3 when cam 10 rotates reciprocatingly slides along operating slide guideway rail is upper and lower, produce relative motion between moving knife 9 and the stationary knife 7 and shear, thus cut pass through 7 of moving knife 9 and stationary knifes the band that confluxes.The utility model embodiment is owing to adopt linear bearing to slide on guide rail, frictional resistance when stationary knife and moving knife relative motion between guide rail and linear bearing reduces, and this frictional resistance keeps substantially constant, the position basically identical that cam is each like this stops after rotating, thereby the position that each shear action is finished rear dynamic knife is all basic identical, having reduced existing automatic guillotine blade position often changes and makes the band that confluxes take place to curl the problem of cisco unity malfunction.In the utility model embodiment, utilize the compression spring pressure that moving knife is pressed on the stationary knife, can regulate pressure between moving knife and the stationary knife by the compression travel of regulating spring within the specific limits, pressure between moving knife and the stationary knife is basicly stable within a certain period of time, thereby the reliability and the durability of mechanism have been improved, simplified the fixed structure of moving knife simultaneously, made complete machine structure simple and practical.
