Yarn cutting machine of the present invention is described as follows by the design principle of sand line broken wire protecting equipment:

The applicant's being designed with in the patent of invention description of " the numerical control yarn cutting machine sand line disconnection protection circuit " of on September 24th, 2013 application " sand line power circuit ", by emergency stop switch SB1, sand line, working table lamp normal open switch K and the formed series circuit of working table lamp TD two ends are connected between node 41 and a secondary coil terminal 26 of single phase poaer supply transformer T, once sand line broken string, described node 41 and out-secondary between 26 four series circuits in parallel with regard to lose AC power, can make coolant pump three phase alternating current motor M1, shelf is three phase alternating current motor M2 up and down reciprocatingly, grease pump load motor M4 and sand line rotary direct current electric motor M3 all lose power supply and are out of service, thereby after sand line broken string, yarn cutting machine is played a protective role, after once the sand line of broken string is connected, make above-mentioned each motor obtain electric, yarn cutting machine can not be proceeded work piece cut processing by original program, and can not damage workpiece to be machined.

In order to make sand line obtain electric rear normal operation, except above-mentioned numerical control yarn cutting machine sand line disconnection protection circuit, also should design respectively and the be in series sand line broken wire protecting equipment for concrete yarn cutting machine of energising of sand line two ends, it comprises the conduction apparatus for assembling structure of shelf upper arm and shelf underarm, the conduction apparatus for assembling structure of described shelf upper arm and shelf underarm is after they are cascaded with the upper and lower two ends of sand line respectively, be connected on again in sand line power circuit, sand line is obtained when electric can normally be moved, out of service after dead electricity, upper lead-in wire on upper lead-in wire packing ring is in series with " sand line power circuit " upper end, and lower lead-in wire on lower lead-in wire packing ring is in series with " sand line power circuit " lower end, by shelf upper arm conduction apparatus for assembling structure and shelf underarm conduction apparatus for assembling structure and He Shaxian lower end, sand line upper end, be in series respectively.The conduction apparatus for assembling structural circuit path of above-mentioned series connection is described as follows:

Shelf upper arm conduction apparatus for assembling structural circuit path is as follows:

The upper inner nut all conducting electricity, upper lead-in wire packing ring and upper outer nut are conjointly sleeved on the upper brass screw external screw thread of brass screw successively, the upper spacer ring collar wall phase crimping of the upper brass screw inner face of upper brass screw the inner and the upper spacer ring of conduction, upper spacer ring is pressed in again on upper arm under ball bearing and upper arm between ball bearing, make ball bearing on upper arm, ball bearing three phase crimping conduction under upper spacer ring and upper arm, the ball bearing outer ring conduction that contacts with ball bearing inner race on upper arm by ball bearing steel ball on upper arm on upper arm, equally, the ball bearing outer ring conduction that contacts with ball bearing inner race under upper arm by ball bearing steel ball under upper arm under the upper arm of ball bearing under upper arm, and on upper arm under ball bearing inner race and upper arm ball bearing inner race be all sleeved on the upper bearing (metal) outer wall of inside race of upper arm bearing inner sleeve, make its conduction, the upper bearing (metal) outer wall of inside race of upper arm bearing inner sleeve and the upper bearing (metal) inner sleeve flange face conduction that is communicated as one, because the upper grip loop port end face of upper grip cover and the upper bearing (metal) inner sleeve flange face close contact of upper bearing (metal) inner sleeve, make the upper grip loop port end face conduction of upper grip cover, again because of the upper grip lower end outer wall of upper grip, upper grip middle part outer wall and upper grip upper end outer wall are installed in the upper grip cover lower end endoporus of upper grip cover, make the upper grip lower end outer wall of upper grip, upper grip middle part outer wall and upper grip upper end outer wall all conduct electricity, and the sand line upper end of sand line is installed in the upper grip lower end sand line clamping slot of upper grip lower end outer wall of upper grip lower end, therefore make sand line upper end conduction, after sand line broken string, the electric packing ring of upper lead-in wire is with regard to dead electricity, make the power-off of sand line power circuit, sand line machine is out of service.

Shelf underarm conduction apparatus for assembling structural circuit path is as follows:

The lower outer nut all conducting electricity, lower lead-in wire packing ring and lower inner nut are conjointly sleeved on the lower brass screw external screw thread of lower brass screw successively, the lower spacer ring collar wall phase crimping of the lower brass screw inner face of lower brass screw the inner and the lower spacer ring of conduction, lower spacer ring is pressed in again on the underarm of conduction under ball bearing and underarm between ball bearing, make ball bearing on underarm, ball bearing three phase crimping conduction under lower spacer ring and underarm, the ball bearing outer ring conduction that contacts with ball bearing inner race on underarm by ball bearing steel ball on underarm on underarm, equally, the ball bearing outer ring conduction that contacts with ball bearing inner race under underarm by ball bearing steel ball under underarm under the underarm of ball bearing under underarm, and on underarm under ball bearing inner race and underarm ball bearing inner race be all sleeved in the lower chuck upper end collar wall of lower chuck cover, make its conduction, again because of the lower chuck upper end outer wall of lower chuck, lower chuck middle part outer wall and lower chuck lower end outer wall are installed in the lower chuck cover lower end endoporus of lower chuck cover, make the lower chuck upper end outer wall of lower chuck, lower chuck middle part outer wall and lower chuck lower end outer wall all conduct electricity, and the sand line lower end of sand line is installed in the lower chuck lower end sand line clamping slot of lower chuck lower end outer wall of lower chuck lower end, therefore make sand line lower end conduction, once after sand line broken string, lower lead-in wire packing ring is with regard to dead electricity, make the power-off of sand line power circuit, sand line machine is out of service.

This yarn cutting machine with sand line power-off protection apparatus advantage be compact conformation, when sand line breaks, can guarantee to make the instant dead electricity of sand line electromechanical source circuit, otherwise, after sand line is connected, can make sand line from power circuit electric and sand line machine is run well.
