It is not stretched out from the both ends of sleeve 1.The lower section of lead screw 12 is provided with a pair of guide rails 15, and a pull rod is provided in each guide rail 15
14, and pull rod 14 can slide vertically in guide rail 15, and pressboard 11, the lower end spiral shell of lead screw 12 are provided between two pull rods 14
Line is equipped with feed screw nut 10, and the two sides of feed screw nut 10 pass through a connecting rod 13 respectively and are hinged with corresponding pull rod 14.
As shown in Fig. 2, the upper end rotation of sleeve 1 is provided with big belt wheel 2, big belt wheel 2 is connect by belt with small pulley 7,
Small pulley 7 is connected in the shaft of motor 9, and motor 9 is threephase asynchronous, and the upside of big belt wheel 2 is provided with clutch 3,
Bearing 16 is provided in big belt wheel 2, the lower end of lead screw 12 is first mounted in the inner ring of bearing 16, then passes through keyway cooperation and clutch
Device 3 is fixedly connected, and there are two spherical grooves for setting on the downside of big belt wheel 2, and two spherical grooves are symmetrically distributed in lead screw 12
Two sides, there are two through-hole, the upper end of each through-hole, which is provided with, adjusts screw 4 for setting in clutch 3, is all provided in each through-hole
It is equipped with cylinder spherical pin 5, the bulb of 5 lower end of cylinder spherical pin matches with spherical groove, and the outer cover of cylinder spherical pin 5 is equipped with pressure
Contracting spring 6, and the lower end of compressed spring 6 is pressed on the surface in bulb.
The machinery of the utility model imitates the power train process of hydraulic clamp cutter tracking protective voltage type paper pressing device are as follows:
Pressboard 11 carries out a stroke and needs 6s, speed 40mm/s, pressure 20000N.Such as Fig. 1, motor 9 is driven
Small pulley 7 rotates, and imparts power to big belt wheel 2 through belt, big belt wheel 2 by cylinder spherical pin 5 first impart power to from
Clutch 3, then transfer power on lead screw 12.Lead screw 12 is screwed with feed screw nut 10, and lead screw 12 rotates, and feed screw nut 10 is by edge
Axis is to up and down motion.Sliding block is installed, one end of connecting rod 13 and sliding block are hinged, the other end and pull rod 14 in feed screw nut 10
Hingedly, drive connecting rod 13 to pass motion to pull rod 14 when feed screw nut 10 moves, pull rod 14 haul this moment pressboard 11 along
Guide rail 15 moves downward, until pushing down quires.Pressboard 11 also will continue to micro pushing after pushing down quires, work as clutch at this time
The degree that 3 pressure reaches suitable will be separated with belt wheel 2 is answered；After quires compresses, so that it may cut-off knife whereabouts cut paper is operated, this
When since cut-off knife is to the impact pressure loading of quires, quires has a small amount of moving down again, and clutch 3 can restore work again automatically at this time
Make, i.e. the tracking of pressboard 11 moves down the identical small amount of moving down, and plays the role of tracking pressure maintaining.After the completion of cutting, cut-off knife rises
Quires is left, pressboard 11 executes backstroke under the action of clutch 3, and motor 9 will drive lead screw 12 to rotate backward at this time,
Connecting rod 13 drives the pull rod 14 on both sides to synchronize upward linear motion, and pressboard 11 is lifted to predetermined position motor 9 and stops turning
It is dynamic.
The machinery of the utility model imitates the working principle of clutch 3 in hydraulic clamp cutter tracking protective voltage type paper pressing device are as follows:
As shown in Fig. 2, placing several compressed springs 6 and cylinder spherical pin 5 in the through-hole of clutch 3, compressed spring 6 will
Cylinder spherical pin 5 is pressed into the spherical groove of big belt wheel 2, and the elastic force for compressing compressed spring, clutch 3 are adjusted with adjusting screw 4
It is connect by key with lead screw 12.Due to the compressed spring 6 in clutch 3 by cylinder spherical pin 5 be pressed into big belt wheel 2 spherical groove
It is interior, so when big belt wheel 2 is rotated by the effect of small pulley 7, cylinder spherical pin 5 be will receive along spherical groove face vertical direction
Active force.Meanwhile its effect also by the frictional force between work spherical, the resultant force of two power can be analyzed to along axis side
To directed force F1Power F along a tangential direction2.Cylinder spherical pin 5 is by power F along a tangential direction2Clutch 3 is passed to, and
It is transmitted on lead screw 12 in a manner of torque by key, by power F in the axial direction1It is transmitted in compressed spring 6.
After adjusting the pressing force that screw 4 sets up compressed spring 6 by control screw-in amount, load suffered by the lead screw 12 smaller
When, F1Less than or equal to the pressing force of compressed spring 6, compressed spring 4 no longer generates compressive deformation, and cylinder spherical pin 5 is still pressed
In the spherical groove of big belt wheel 2, clutch 3 functions as shaft coupling；When the load suffered by the lead screw 12 is greater than limit value, F1
Greater than the pressing force of compressed spring 6, compressed spring 6 generates compressive deformation, and cylinder spherical pin 5 and big belt wheel 2 disengage, clutch 3
Play protection (separation).At this moment big belt wheel 2 dallies, and lead screw 12 does not rotate.The load suffered by the lead screw 12 is decreased to limit value
When following, cylinder spherical pin 5 is pressed again by the spherical groove of big belt wheel 2 by compressed spring 6, and clutch 3 restores shaft coupling again
Effect, lead screw 12 restore rotation.So clutch 3 can effectively limit output torque, guarantee to disengage in time when overload,
It can resume work automatically again, can play the role of tracking pressure maintaining.According to the actual conditions of cut paper, by adjusting screw
4 change the pressing force of compressed spring 6, to adjust 11 operating pressure of pressboard, prevent paper from rupturing and being displaced, it is ensured that cut matter
Amount.
It is to be noted that the pressure of pressboard 11 should cut hard paper or cardboard more greatly when cutting general paper
When, the pressure of pressboard 11 is answered smaller.
