Moving up and down, find suitably height according to the scale of location-plate support, different height determines medicine
The granular size of sample and cut-off length, when fixing nut screwing clamping, tubulose or strip gunpowder perpendicular
Straight enter length fixed, the front end of strip or tubular powder is withstood on the upper surface of location-plate, and sheet
The transversely cutting invariant position of cutter, above location-plate, action carries out crushing and cut off action, dynamic
During work, cut-off chip falls in housing.
The rear end of described upper knife plate 3 is provided with rotating shaft 30, described rotating shaft and frame pivot joint, makes on described
Knife plate can open, around axle upset, the gunpowder sample draft machine internal structure being easy to safeguard below upper knife plate.
Operationally, upper knife plate is suppressed fixing by the steady pin 16 of frame both sides, when a sample completes
After, extract steady pin, be flipped up upper guide plate starting and beneficially clean.
Such as Fig. 4, described upper slitter intralaminar part is provided with push-pull electromagnet 27, tongue tube 26 and protection gear
Plate 28, described upper knife plate and protection baffle plate are copper or non-metallic material, and described tongue tube is embedded in band
In the upper surface in shape medicine sample hole 9 and column/granular medicine sample hole 7, tongue tube will not adhesive the most at ordinary times.
The iron core of push-pull electromagnet is fixing with one end of protection baffle plate to be connected, and the other end of protection baffle plate can hang down
Direct puncture crosses described medicine sample through hole, when protection baffle plate is through medicine sample through hole, is closed by this medicine sample through hole.Dry
Reed pipe is connected formation loop, when making described tongue tube close, push-pull electromagnet with push-pull electromagnet
Iron core release and close medicine sample through hole；When described tongue tube disconnects, the iron core of push-pull electromagnet is received
Return and decontrol medicine sample through hole, close medicine sample through hole primarily to prevent metal object from entering medicine sample through hole
Damage sheet cutter.
As Fig. 1,2, described cutter 4 is provided with the driving hole 29 fixing to be connected with described fork, transmission
The rear portion of sheet cutter is located in hole, and front end is the edge of a knife of sheet cutter, the front edge at sheet cutter be provided with " one " type,
" V " type, " W " type edge of a knife 20, the middle part of sheet cutter is fixed with the stamping knife of the cylindricality in the face of front end
6.For ensureing long service life, using hardness is the material of HRC50-55, and the edge of a knife is that rapid wear can
Demolition part, can change when damaged.The alloy of high-hardness is expensive, for reducing cost,
High-hardness can be used at knife-edge part, use common material at remaining position.Do at sheet cutter and come and go fortune
Time dynamic, the edge of a knife on sheet cutter is unified does cut-out action, and the sampling edge of a knife of the most multiple gunpowder can be simultaneously
Work.
Described bar-shaped medicine processing machine 35 is located at the milling cutter side of main shaft, is provided with feed shaft 32, bar-shaped medicine
Fixed mount 14 and manual rocking handle 15, manual rocking handle is fixing with feed shaft to be connected, and feed shaft screw thread promotes
Bar-shaped medicine fixed mount axially-movable.Described bar-shaped medicine fixed mount 14 is provided with bar-shaped medicine fixing hole 38 and rod
Shape medicine clamp nut 39, described bar-shaped medicine clamp nut is used for solid through the hole wall of bar-shaped medicine fixing hole
Fixed bar-shaped medicine.Described bar-shaped medicine fixed mount 14 is provided with milling cutter protective cover 12, and milling cutter protective cover is by hinge
Chain is connected with bar-shaped medicine fixed mount.The centrage of bar-shaped medicine fixing hole 38 is with the centrage difference of milling cutter not
Many on a horizontal plane, when bar-shaped medicine fixing hole 38 fixes bar-shaped medicine and when milling cutter is close, milling
Cutter becomes wood shavings shape medicine sample from the bar-shaped medicine of side cut.
Described bar-shaped medicine processing machine 35 is fixedly arranged on bar-shaped medicine processing machine support 37, and described bar-shaped medicine adds
Work machine support 37 is connected with frame by bar-shaped medicine frame hinge 31, makes described bar-shaped medicine processing machine 35
It is easy to turn to cleaning.Operationally, the opposite side of bar-shaped medicine processing machine support 37 is fixed in housing
The card arranged is buckled.
Reducing motor 1 rotating speed is 60r/min, drives main axis, belt transmission with belt 2 transmission
The equipment of being beneficial to and operation safety, when sheet cutter is hindered, will not rigid drive main axis.Main shaft
5 and fork 18 impart power to various cutter.Add man-hour, first cleaning draft machine housing in and
Cutter, workflow is as it is shown on figure 3, sheet cutter institute band cutter is under the drive of main shaft, by swing link transmission
Moving reciprocatingly, the edge of a knife of sheet cutter front end does crushing cut-out action simultaneously, when having gunpowder in medicine sample hole,
Under the cut-out action of cutter, ring gun propellant is punched to the medicine sample of uniform shapes by stamping knife, and banding is sent out
Penetrating medicine by the flat mouth edge of a knife of " one " type according to being positioned the length cut-out that plate sets, granular medicine is by " V "
The type edge of a knife squeezes broken, and tubular powder is squeezed medicine sample that is broken and that be cut to unified size by " W " type edge of a knife, with this
Meanwhile, main shaft also rotates at the milling cutter driving its termination, fixes bar-shaped medicine in bar-shaped medicine fixed mount
After, shake manual rocking handle and make bar-shaped medicine fixed mount move to milling cutter, the milling cutter bar-shaped medicine to being touched
Cutting is required wood shavings shape medicine sample, and falls in the medicine sample flange 33 of lower section.At sheet cutter simultaneously
When processing multiple gunpowder, processed medicine sample chip falls in housing, is spaced apart not in housing
Between same medicine sample is collected, it is simple to after processing action stops, collecting the medicine sample processed respectively.
