Tricot machine steel wire flower comb pinpoint clearing device

Technical field

The present invention relates to tricot machine technical field, especially a kind of tricot machine steel wire flower comb pinpoint clearing device.

Background technology

Multi-bar warp knitting machine by with schlagblech technology, a Chinese mugwort state jacquard pattern design technology, electronics horizontal movement technology fusion, have become as the openwork jacquard class lace machine Special machine for producing type that model structure configuration is various, product flower pattern abundant species, the ability that rockets are the strongest. In the R&D process of multi-bar warp knitting machine, the transverse motion of steel wire flower comb is dependent on servomotor and what air spring jointly controlled; Owing to steel wire flower comb quantity is more, therefore from space and two aspects of cost, it is impossible to install null pick-up for steel wire flower comb. When not installing null pick-up, how allowing numerous steel wires spend comb unified or carrying out high accuracy fixed point recurrence zero-bit in units of active line is one technical barrier urgently to be resolved hurrily of multi-bar warp knitting machine.

Traditional zero scheme is floating zero-bit, is namely manually set a zero point. Its implementation is when installation and debugging, the motor of manual fine-tuning sley bar carrys out the rotating disk on rotary electric machine to move sley bar to some suitable position by steel wire or steel band, tune machine personnel think that this position can as the reference zero-bit of this sley bar, just click the ACK button of system, be zero by the variable recording the displacement of this sley bar in systems soft ware; The shortcoming of the method is that all sley bars need tune machine personnel to carry out zero-bit confirmation, complex operation one by one, and workload is big and cannot ensure precision.

Summary of the invention

In order to overcome existing multi-bar steel wire flower comb to be difficult to install the deficiency of null pick-up because of the restriction of motor mounting space, the invention provides a kind of tricot machine steel wire flower comb pinpoint clearing device.

The technical solution adopted for the present invention to solve the technical problems is: a kind of tricot machine steel wire flower comb pinpoint clearing device, including drive motor, motor mounting plate, driving pulley, fixed point baffle plate and guiding steel wire, drive motor is bolted on the back side of motor mounting plate, fixed point baffle plate is fixed on the front of motor mounting plate, fixed point baffle plate is pagoda shape, fixed point baffle plate is provided with six catch point, catch point place adopts arc transition design, driving pulley is fixed on the driving axle of drive motor, the driving pulley back side is provided with projection, catch point that is protruding and that pinpoint on baffle plate contacts, guiding steel wire is bolted on motor mounting plate side.

According to another embodiment of the invention, farther including on motor mounting plate uniform porose one, hole one is formed around screwed hole one, and the driving axle of drive motor is fixed in hole one by bolt mate with threaded holes one.

According to another embodiment of the invention, farther including driving pulley in the form of annular discs, centre is drilled with hole two, and hole two is formed around screwed hole two, and driving pulley is fixed on the driving axle of drive motor by bolt mate with threaded holes two.

According to another embodiment of the invention, the catch point height on fixed point baffle plate is farther included different.

According to another embodiment of the invention, farther include guiding steel wire S-type, the section of being divided into, section two, section three and Duan Sisi section, Duan Yi, section two place plane vertical with the plane of section three, section four place.

The invention has the beneficial effects as follows, this device utilizes machinery catch point to replace null pick-up, replaces zero-bit approach signal with the torque signal that transfinites, efficiently solves multi-bar steel wire flower comb and be difficult to install the defect of null pick-up because of the restriction of motor mounting space. Utilize the torque limit function of servo-driver, adopt the control mode of position torque mixture control pattern, it is possible to implement when multi-bar steel wire flower comb is without null pick-up, mechanical zero controls with the fixed point zero of technique zero-bit. This mode, compared with the return-to-zero mode of traditional floating zero-bit, adjusts machine workload to greatly reduce and in hgher efficiency, and sley bar repeatedly makes zero position favorable reproducibility, system longtime running safety and reliability.
