In the novel power supply circuit, after the trigger subcircuit is powered on to work, two sets of time control switches A1 and A2 respectively output power supplies at intervals under the action of internal circuits and under the action of 3 and 4 foot output power supply time set by technicians to enter two power supply input ends of relays K and K1 (the power supplies respectively enter an anode power supply input end of a relay K, K1 through reed pipes GH and GH 1; for example, the time control switch A1 outputs 10 seconds of power supply firstly, then outputs 10 seconds of power supply every 10 seconds in a circulating mode, outputs 10 seconds of power supply every 2 outputs 10 seconds of power supply every 10 seconds in a circulating mode), thus, the relay K can be firstly switched on by the electrician for 10 seconds, the two control power supply input ends and the two normally open contact ends are respectively closed for 10 seconds, then circularly electrifying every 10 seconds to work and attracting for 10 seconds, and respectively closing two control power supply input ends and two normally open contact ends for 10 seconds; the relay K1 is electrified to work for 10 seconds to attract the two control power supply input ends and the two normally open contact ends of the relay K1 to be closed for 10 seconds respectively, and then the relay K1 is circularly electrified to work for 10 seconds to attract the two control power supply input ends and the two normally open contact ends of the relay K1 to be closed for 10 seconds respectively.

Fig. 1 and 2 show, in the time that relay K got electric actuation, because two normally open contact ends of relay K and motor reduction mechanism M plus-minus two-pole power input end connect respectively, so motor reduction mechanism M can get its power output shaft of electrician work and drive lead screw 6 anticlockwise rotation at this moment, and then the external screw thread of lead screw 6 acts on the internal thread through-hole 71 at upper plate 7 middle part, upper plate 7 downstream, and through four axostylus axostyles (linear bearing 3 is the downstream direction of axostylus axostyle) drive 1 downstream of impressed watermark version, the leather that the 1 lower extreme contact of impressed watermark version was located on bottom plate 5 was suppressed the leather and is gone out the line decorations 10 seconds. After the embossing plate 1 just moves for 10 seconds from top to bottom to emboss leather into decorations, the magnet 9 is just close to the reed switch GH at the front lower end of the left side of the supporting plate 11 at the moment, so the internal contact of the reed switch GH is opened, because the reed switch GH is connected between the 3 pins of the time control switch A1 and the positive power input end of the relay K in series, the relay K can lose power and can not attract any more at the moment, the motor speed reducing mechanism M can not rotate any more, the embossing plate 1 does not move downwards any more, and the phenomenon that the whole work of the equipment is influenced due to the overlarge descending distance is prevented. In the time that relay K1 got electric actuation, because two normally open contact ends of relay K1 and motor reduction mechanism M negative and positive two poles of the earth power input end connect respectively, motor reduction mechanism M can get its power output shaft of electrician work and drive lead screw 6 clockwise rotation at this moment, and then the external screw thread of lead screw 6 acts on the internal thread through-hole 71 at upper plate 7 middle part, upper plate 7 upward movement, and through four axostylus axostyles (linear bearing 3 for the axostylus axostyle goes upward the direction) 1 upward movement of driving embossing version, embossing version 1 upper end was located backup pad 11 upper portion lower extreme during 10 seconds. After the upper end of the embossing plate 1 is just positioned at the lower end of the upper part of the supporting plate 11, the magnet 9 is just close to the reed switch GH1 at the front upper end of the left side of the supporting plate 11, so that the internal contact of the reed switch GH1 is opened, and because the reed switch GH1 is connected between the pin 3 of the time control switch A2 and the positive power input end of the relay K1 in series, the relay K1 can lose power and can not be attracted any more, the motor speed reducing mechanism M can not rotate any more, the embossing plate 1 can not move upwards any more, and the phenomenon that the whole work of the equipment is influenced due to the overlarge ascending distance. Through above-mentioned circuit and mechanism combined action, control circuit gets electric work back, embossing plate 1 will be at every interval 10 seconds and carry out the impressed watermark to constantly getting into on the bottom plate 5 and the leather under the embossing plate 1 (10 seconds that embossing plate 1 went upward, one section finished product behind the rolling equipment rolling impressed watermark, or one section finished product behind the manual rolling impressed watermark of operating personnel, there is not impressed watermark department reentrant bottom plate 5 upper end and 1 lower extreme of embossing plate in leather next section, motor reduction mechanism M can control again that embossing plate 1 carries out the impressed watermark to the leather like this, reach continuous production's purpose. It should be noted that, in the present application, the time for the time control switches a1 and a2 to output power is not fixed, if the leather thickness is thick, the time for the power output by the time control switches a1 and a2 is set to be relatively short (the downlink distance is relatively small), and if the leather thickness is thin, the time for the power output by the time control switches a1 and a2 is set to be relatively long (the downlink distance is relatively small), which meets the actual requirement. In order to ensure that the embossing plate 1 stops working after embossing leather, a technician needs to adjust the heights of the two reed pipes GH and GH1 respectively, and in short, the embossing plate 1 can stop working in time (and ascend to a certain height to stop working) after embossing the leather. Relay K, K1 is a 48V dc relay. The reed switches GH and GH1 are glass-shell normally-closed contact type reed switches of type MKA 14103.
