The semi-automatic joining device of described rotor spinning machine, linkage is by pressure pin, handle, roller seat, spring, connecting rod, rotating shaft and triggering piece are formed, and the roller seat middle part is loaded on the frame by pressure roller shaft, one end is connected by axle II with connecting rod, pressure pin is loaded on the frame by the pressure pin axle that is fixed thereon, and pressure pin and connecting rod flexibly connect by an I and handle middle part, and an end of handle is connected with the triggering piece by axle III, triggering the activity of going back of another place of piece is loaded in the rotating shaft, when drawing yarn rubber roll disengaging delivery roller, an end is loaded on the frame, and the spring that the other end is loaded on the roller seat is in tensioning state.

The semi-automatic joining device of described rotor spinning machine, electromagnet I is fixed on the frame, and is drawing between yarn rubber roll and the spinning organ, electromagnet II is fixed on the frame, iron core II on this electromagnet II can with trigger piece and contact, yarn break sensor is fixed on the frame, and is positioned at and draws above the yarn rubber roll.

The utility model is owing to adopted above-mentioned technical solution, thereby have following beneficial effect: (one) is simple in structure, easy and simple to handle, can improve the quality of joint, similar with the joint outward appearance of full-automatic rotor spinning machine, joint quality has uniformity, thereby avoids the uncertainty of manual splice; (2) be the requirement that has reduced operator's technical quality, improved the success rate of joint greatly.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Structural representation when Fig. 2 is the semi-automatic joining device duty of the utility model rotor spinning machine.

Five, the specific embodiment

As shown in Figure 1, the semi-automatic joining device of rotor spinning machine comprises and draws yarn rubber roll 9, delivery roller 13, controller 15, signal lamp 16, press button 17, the electromagnet I11 that contains iron core I10, the electromagnet II22 that contains iron core II21, linkage 23 and yarn break sensor 5, linkage 23 is by pressure pin 2, handle 7, roller seat 8, spring 14, connecting rod 18, rotating shaft 19 and triggering piece 20 are formed, roller seat 8 middle parts are loaded on the frame 6 by pressure roller shaft 26, and an end is connected by axle II27 with connecting rod 18, and pressure pin 2 is loaded on the frame 6 by the pressure pin axle 24 that is fixed thereon, pressure pin 2 and connecting rod 18 flexibly connect by axle I25 and handle 7 middle parts, one end of handle 7 is connected with triggering piece 20 by an III28, and triggering piece 20 another places also activity are loaded in the rotating shaft 19, when drawing yarn rubber roll 9 disengaging delivery rollers 13, one end is loaded on the frame 6, the spring 14 that the other end is loaded on the roller seat 8 is in tensioning state, signal lamp 16, press button 17, electromagnet I11, electromagnet II22 and yarn break sensor 5 are connected with controller 15 respectively.Controller 15 can be a time relay controller or programmable controller PLC, and the time difference of required joint can be adjusted as requested.Whether the effect of yarn break sensor 5 is to measure yarn 4 to exist, and this sensor 5 is connected with controller 15, so as rupture or joint stop when getting nowhere reel for yarn around.Signal lamp 16 is as warning device, and it reports to the police signal lamp 16 bright lamps by sensor 5 by controller 15 when yarn 4 does not exist.The press button 17 of controller 15 is installed in the scope that the operative employee can access.Electromagnet I11 is fixed on the frame 6, and drawing between yarn rubber roll 9 and the spinning organ 12, electromagnet II22 is fixed on the frame 6, and the iron core II21 on this electromagnet II22 can contact with triggering piece 20, yarn break sensor 5 is fixed on the frame 6, and is positioned at and draws yarn rubber roll 9 tops.Iron core I10 can or unclamp by electromagnet I11 inspiration under the effect of controller 15, and iron core II21 also can or unclamp by electromagnet II22 inspiration under the effect of controller 15.When handle 7 presses down, make the yarn rubber roll 9 that draws that is loaded on the roller seat 8 break away from the certain distance of delivery roller 13, pressure pin 2 lifts bobbin 1, trigger the rotating shaft 19 that piece 20 can install around on frame 6 simultaneously and rotate, and compression iron core II21 is to electromagnet II22.

Specific operation process is: after yarn 4 fractures, at first carrying out joint prepares, as shown in Figure 1, this moment, the operative employee can be with subordinate pressure handle hand 7, make pressure pin 2 lift bobbin 1 respectively by connecting rod 18 and break away from friction roller 3, roller seat 8 lifts and drives and draws yarn rubber roll 9 disengaging delivery rollers 13, and making has certain distance between the two, and spring 14 enters tensioning state here.Meanwhile, handle 7 drives and

triggers pieces

20 and 19 iron core II21 compressed into electromagnet II22 around the shaft, electromagnet II22 is got electric iron core II21 is held.At this moment the operative employee can unclamp handle 7, finds out that yarn 4 on the bobbin 1 passes sensor 5, draws yarn rubber roll 9, iron core I10, and heavy then yarn is gone into the exit of spinning organ 12.At this moment just enter normal spinning duty, as shown in Figure 2.Press push switch 17, controller 15 is started working, and feeds cotton beginning, and behind the preset time interval, electromagnet I11 gets electric inspiration iron core I10, and heavy yarn begins.Simultaneously electromagnet II22 dead electricity flicks iron core II21 and triggers piece 20, and draw the effect that yarn rubber roll 9 at one end is loaded on the spring 14 on the frame 6 and contact with delivery roller 13 down, and the pressure certain with its maintenance.By the motion transmission of linkage 23, pressure pin 2 falls after rise, and bobbin 1 is dropped on the friction roller 3, the beginning of reeling, and yarn 4 joints are finished.If yarn 4 joints are unsuccessful, sensor 5 reaches controller 15 with signal, makes signal lamp 16 shinny warnings.At this moment, need carry out joint again.
