The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed, complete explanation:

As shown in Figure 1, the semi-automatic joining device of rotor spinning machine of the present utility model, comprise roller 9, draw yarn axle 13, controller 15, signal lamp 16, press button 17, the heavy yarn electromagnet 11 that contains iron core I10, the doff electromagnet 22 that contains iron core II21, leather roller seat 8, linkage 23, broken yarn inductor 5, support 6, support arm 19 and last item seat 30, wherein signal lamp 16, press button 17, heavy yarn electromagnet 11, doff electromagnet 22 is connected with controller 15 respectively with broken yarn inductor 5, support arm 19 1 ends are connected with iron core II21 on the doff electromagnet 22 by axle V29, spring II20 is housed on the iron core II21, last item seat 30 is connected with support arm 19 middle parts by axle IV28, linkage 23 is by holder yarn bar 2, handle conjunction 7, spring I14, spring III31, connecting rod support arm 18 is formed, holder yarn bar 2 is installed on the support 6 by the holder yarn bar rotating shaft 24 that welds together with it, holder yarn bar 2 and connecting rod support arm 18 flexibly connect by the middle part of axle I25 and handle conjunction 7, one end of handle conjunction 7 is supported on the support arm 19, the end of spring I14 is installed on the support 6, the other end is installed on the leather roller seat 8, the end of spring III31 is installed on the connecting rod support arm 18, the other end is installed on the handle conjunction 7, connecting rod support arm 18 is connected with leather roller seat 8 one ends by axle III27, leather roller seat 8 is installed on the support 6 by axle II26, heavy yarn electromagnet 11 is fixed on the support 6, and be positioned at the place ahead of roller 9 and the upper right side of spinning organ 12, the doff electromagnet is fixed on the support 6, broken yarn inductor 5 is fixed on the support 6, and is positioned at roller 9 tops.When yarn axle 13 was drawn in roller 9 disengagings, spring I14 was in tensioning state; Iron core I10 can make heavy yarn electromagnet 11 adhesives or unclamps under the effect of controller 15; Iron core II21 can make 22 adhesives of doff electromagnet or unclamps under the effect of controller 15; When handle conjunction 7 presses down, the roller 9 that is installed on the leather roller seat 8 is broken away from draw yarn axle 13 certain distances, support arm 19 supports an end of handle conjunction 7, and holder yarn bar 2 lifts bobbin 1.

After yarn 4 broken ends, at first carrying out joint prepares, this moment, the operative employee can press handle conjunction 7 with subordinate, make holder yarn bar 2 lift bobbin 1 respectively by connecting rod support arm 18 and break away from take up roll 3, leather roller seat 8 lifts and drives roller 9 disengagings and draws yarn axle 13, making has certain distance between the two, and at this moment spring I14 enters tensioning state.Meanwhile, because the elastic force of spring II20 makes support arm 19 be in the state of being tilted to the right all the time, when pressing down handle conjunction 7, an end of handle conjunction 7 can be supported by support arm 19, thereby the roller that is installed on the leather roller seat 89 is broken away from draw the certain distance of yarn axle 13, holder yarn bar 2 lifts bobbin 1.But operative employee's release handle conjunction 7 at this moment, the yarn of finding out on the bobbin 14 passes broken yarn inductor 5, roller 9 and iron core I10, is cut to suitable length, and heavy then yarn is finished the joint preparation to the outlet of spinning organ 12 in.

As shown in Figure 2, during joint, press press button 17, controller 15 is started working, and feeds cotton beginning, behind the preset time interval, and heavy yarn electromagnet 11 energising moment pull-core I10, heavy yarn is finished.Doff electromagnet 22 energising moment pull-core II21 are tilted to the right thereby drive support arm 19 simultaneously, and handle conjunction 7 breaks away from support arm 19, and roller 9 contacts with drawing yarn axle 13 under the effect of spring I14, and the pressure certain with its maintenance.By the motion transmission of linkage 23 and the tension of spring III31, holder yarn bar 2 falls after rise, and bobbin 1 is dropped on the take up roll 3, the beginning of reeling, and yarn 4 joints are finished.

If yarn 4 joints are unsuccessful, broken yarn inductor 5 passes to controller 15 with signal, and signal lamp 16 is powered alarm, and at this moment needs joint again.

In above-mentioned Yarn connecting operating process, electromagnet is just moment energising adhesive all the time, does not need long-time energising; In addition, owing on the contained iron core II of doff electromagnet spring II is housed, the elastic force of spring II makes support arm be in the state of being tilted to the right all the time, by pressing down the handle conjunction, one end of handle conjunction can be lived by arm supports, draw yarn axle certain distance thereby the roller that is installed on the leather roller seat is broken away from, holder yarn bar lifts bobbin, does not need the energising of doff electromagnet just can realize the joint preparation; Therefore, the semi-automatic joining device of rotor spinning machine of the present utility model has solved electromagnet because of need be in the problem that energising or long-time "on" position are damaged easily always; In addition, by a last item seat is set, solved when no power, roller is pushed down all the time and is drawn the yarn axle, causes the roller easy deformation, influences the problem of resultant yarn effect.
