Abstract
The utility model relates to an electromagnetic actuating mechanism for thread adjusting devices, which is particularly used for knitting circular machines. The electromagnetic actuating mechanism comprises an electromagnet, a switch angle square, a draw board angle square, and two tension springs. The utility model is characterized in that the electromagnet is arranged at the inner sides of a pair of wall boards of a thread adjusting device and between a thread adjusting clip and a pulling board of the thread adjusting device; the electromagnet corresponds to the upper part of a swinging lever of the thread adjusting device; an iron core of the electromagnet corresponds to an angle square arm of the switch angle square; the switch angle square is pivoted on the wall boards; the lower arm of the switch angle square corresponds to the lower arm of the draw board angle square; the draw board angle square is pivoted on the pulling board; one end of the two tension springs is fixed to the angle square arm and the pulling board, and the other end of the two tension spring is fixed to the wall boards and the lower arm of the draw board angle square. The utility model has the advantages of compact components, small volume, etc.
Description
The utility model discloses a kind of electromagnetic actuator, particularly a kind of electromagnetic actuator that is exclusively used in the needle-thread tensioning control device on the circular knitting machine.
Because the electromagnet of the electromagnetic actuator of existing needle-thread tensioning control device is provided in a side of the outside of wallboard, therefore, some space is wasted on the one hand; Make bulkyization of whole needle-thread tensioning control device on the other hand; Make on the one hand the controlled form of switch angle square of this mechanism reasonable inadequately again, thereby open the switch angle square and need enough active forces, and take place often not cause makeing mistakes, influence reliability, the stability of circular knitting machine work because of opening.
Task of the present utility model be to provide a kind of electromagnet installation site rationally, compact, little, the rational electromagnetic actuator of switch angle square controlled way of volume of parts combination.
Task of the present utility model is finished like this, a kind of electromagnetic actuator, it comprises: electromagnet 4, switch angle square 1, arm-tie angle square 16, extension spring 7,14, described electromagnet 4 is provided in wallboard 2 inboards of a pair of parallel setting of needle-thread tensioning control device, and between the line transfer folder 18 and pull plate 13 of needle-thread tensioning control device, and top corresponding to the rocking lever 17 of needle-thread tensioning control device, its iron core 5 is corresponding to the angle square arm 6 of switch angle square 1, switch angle square 1 is hubbed on a pair of wallboard 2, its underarm 19 is corresponding with the underarm 11 of arm-tie angle square 16, arm-tie angle square 16 is hubbed on the pull plate 13, extension spring 7, an end of 14 is separately fixed on the angle square arm 6 and pull plate 13 of switch angle square 1, and the other end is separately fixed on the underarm 11 of wallboard 2 and arm-tie angle square 16.
The utility model has been optimized the allocation position of electromagnet 4 owing to adopted said structure, and the space is rationally utilized; The parts combination is compact, reasonable, the little volume of having changed; Electromagnet 4 can reasonably act on switch angle square 1, has guaranteed to open the reliability of switch angle square 1.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is the utility model electromagnetic actuator structure chart.
Electromagnet 4 of the present utility model is provided with in vertical state.Because a cover needle-thread tensioning control device will have the pull plate 13 of line transfer folder more than 18 and two more than two, so the utility model electromagnetic actuator needs to set with its equivalent.Every block of electromagnet 4 of each electromagnetic actuator is screwed in after compound plate hole 23, electromagnet fixing hole 8 be installed with successively by compound plate 22 and by hold-down screw 21, again with each switch angle square 1 hub setting in the affixed drive-connecting shaft 9 of a pair of wallboard 2 on, at last that each arm-tie angle square 16 is hinged with the every pull plate 13 of needle-thread tensioning control device by bearing pin 15.Extension spring 7 can realize that each electromagnet 4 is connected with computer by circuit 12 respectively by an extension spring fixed axis 10 that is fixedly arranged on the wallboard 2 with the fixing of wallboard 2.
After computer sends to electromagnet 4 with work order, after electromagnet 4 is accepted the work order of the signal of telecommunication, under the effect in magnetic field, its iron core 5 rises, act on the angle square arm 6 of switch angle square 1, and the pulling force that overcomes extension spring 7 is thrown off the underarm 19 of switch angle square 1 and the underarm 11 of arm-tie angle square 16, under the restoring force effect of extension spring 14, make upper arm 20 hypsokinesis of arm-tie angle square 16 and enter the working region of lance 25 of the total output arm 24 of needle-thread tensioning control device, along with 24 swings of external force pulling total output arm, making arm-tie angle square 16 is that stress point drives pull plate 13 and moves down to be located at the pin 3 of raming on the pull plate 13, again by the connecting plate 26 of needle-thread tensioning control device, rocking lever 17, the interlock effect of location-plate 27, the line transfer folder 18 that drive is fixedly arranged on the location-plate 27 moves down, and makes line transfer press from both sides 18 clampings and the line feeding zone that yarn goes downwards to circular knitting machine and carry out line transfer.Otherwise if computer is not sent out work order, then electromagnet 4 is failure to actuate, iron core 5 can not rise, the underarm 19 of switch angle square 1 contacts with the underarm 11 of arm-tie angle square 16, the upper arm 20 of arm-tie angle square 16 does not just enter the working region of lance 25 of the total output arm 24 of needle-thread tensioning control device, the 24 upper and lower swings of total output arm are in disarmed state, and pull plate 13, connecting plate 26, rocking lever 17, location-plate 27 are in static state, and line transfer folder 18 can not be driven.
Owing to the line transfer folder 18 that need establish on the needle-thread tensioning control device more than two, thereby correspondingly the utility model electromagnetic actuator is equivalent and sets with it, thereby by the alternating movement of a plurality of electromagnetic actuators, and the driving mechanism by needle-thread tensioning control device, cut line ball, payingoff mechanism waits the alternately line transfer that realizes a plurality of line transfers folders 18.
