Machine drives wire storage tube to carry out iterative motion between left and right stroke collision block, and this structure has following problem：
1. since positive and negative rotation wire is rotating forward --- stopping --- the reversion realization by motor, and AC electrical
For machine in the moment from stopping to starting, full-voltage starting electric current is 5~7 times of rated current, and energy consumption increases.It is larger for capacity
Power grid will be caused to impact when electric motor starting, destroy the normal operation with power grid miscellaneous equipment.In addition, to the stator of motor itself
Prodigious impact force is generated on coil and rotor cage item, reduces electrical machinery life.
2. starting torque when motor direct full pressure start-up is about 2 times of nominal torque, for guide rail, gear, leading screw
Equal transmission parts impact is big, and motor speed rises quickly when accelerating abrasion, and starting, and lubricating oil tends not to be in time,
Influence the service life of transmission parts.
3. controlling motor forward/backward rotation circuit to be constantly powered and power off, electric components such as contactor, stroke are controlled
Continual circulation action, the contacts of relay such as switch, protection electric appliance easy to produce electric arc, or even can be melted together generation mistake
Operation, increased care cost.
4. due to being connected with shaft coupling between motor and wire storage tube, motor it is frequent it is positive and negative in the twinkling of an eye, shaft coupling
By prodigious shearing force, its transmitting accuracy is affected, substantially reduces the service life of shaft coupling.

Specific implementation mode
Embodiment one：
A kind of silk drive mechanism of linear cutting machine, including motor 1, wire storage tube 4, further include having crank and rocker mechanism 2, gear
The output shaft 11 of rack gear 3, motor is connect with the crank end of crank and rocker mechanism 2, the rocking bar of crank and rocker mechanism 2
End is connect by the rack and pinion drive mechanism 3 with the transmission shaft 41 of wire storage tube.
The crank and rocker mechanism 2 includes crank 22, connecting rod 24, balance wheel 26, and one end of crank 22 is fixed by crank
Key 21 is fixed on the output shaft 11 of motor, to realize the function of crank；The other end of crank 22 passes through hinge 23 and connecting rod
24 one end connection, to realize the function of revolute pair；The other end of connecting rod 24 passes through fastener 25 --- fastening nut and balance wheel
26 connections, balance wheel 26 are mounted on balancing arbor 261, realize the function of rocking bar, i.e., positive and negative rotating function.Balance wheel 26 also passes through gear teeth
Strip transmission mechanism 3 is connect with the transmission shaft 41 of wire storage tube.
The rack and pinion drive mechanism 3 includes sector rack 31, wire storage tube transmission gear 32, and sector rack 31 is installed
On the circumference of balance wheel 26, wire storage tube transmission gear 32 is mounted on the transmission shaft 41 of wire storage tube, sector rack 31 and wire storage tube
Transmission gear 32 is intermeshed.
In order to make wire storage tube transmission gear 32 that wire storage tube 4 be driven to realize positive and negative rotation, on the circumferential edges of the balance wheel 26
Equipped with a guide groove 262, the sector rack 31 is socketed in the guide groove 262, and sector rack 31 can be in guide groove
It is free to slide in 262, and it is separately installed with a block 33 at the both ends of sector rack 31, so as to fixed sectors rack, pendulum
Swinging for wheel can drive sector rack 31 to engage the 32 progress positive and negative rotation of wire storage tube transmission gear.
In order to make forward and backward switching instant there are one the process buffered, the distance between two blocks can be pulled open, that is, are kept off
Distance is more than 0 between end of the block 33 away from sector rack 31.Since wire storage tube 4 is wound with molybdenum filament, resistance is than sector rack
31 guide groove 262 slide resistance it is big, so when balance wheel 26 is swung to the right, sector rack 31 is by wire storage tube transmission gear 32
Block it is motionless, when balance wheel 26 continuation swing to the right when, the block 33 positioned at the left side withstands the left side of sector rack 31 and drives fan
Shape rack 31 turns right, and at this moment 31 ability of sector rack and the engagement of wire storage tube transmission gear 32 is rotated forward.So in this mistake
Since there are a certain distance between block 33 and sector rack 31 in journey, play the role of buffering in the twinkling of an eye positive and negative, similarly,
Similarly there is buffering when balance wheel 26 swings realization reversion to the left.
Balance wheel 26 is radially provided with a regulating tank 263 also between its wheel rim and balancing arbor 261, the connecting rod 24
The other end passes through fastener 25 --- and fastening nut is fixed on the regulating tank 263.The amplitude of fluctuation of balance wheel 26 can be by changing
Become fixed position of the connecting rod 24 in regulating tank 263 to realize, when needing the amplitude of the swing of balance wheel 26 smaller, one end of connecting rod 24
It can be fixed toward close to the edge of balance wheel 26 by fastener 25；When needing the amplitude of the swing of balance wheel 26 larger, the one of connecting rod 24
End can be fixed by fastener 25 toward at balancing arbor 261.
Wire storage tube 4 can be controlled by the size for changing wire storage tube transmission gear 32 and the length for changing sector rack 31
The number of turns of forward and backward.
The present invention action process be：
Motor 1 is rotated always forward or backwards after starting, and balance wheel 26 or so is controlled no by crank and rocker mechanism
The swing stopped makes sector rack 31 that wire storage tube transmission gear 32 be driven to realize positive and negative rotation, reaches the effect of control 4 positive and negative rotation of wire storage tube
Fruit.
