Technical field

The utility model belongs to textile machine manufacturing technology field, and particularly a kind of computer flat knitting machine plays the actinobacillus device that colludes the line pin in the end.

Background technology

In the Computerized flat knitting machine of field of textile machinery, play the actinobacillus device that colludes the line pin in the end building block that is absolutely necessary.At present, line aciculiform shape is colluded as shown in Figure 1 in the end of rising of Computerized flat knitting machine both at home and abroad, and the line pin that colludes shown in Figure 1 is put into the unwrapping wire pin shown in Fig. 2 and 3, and both closely cooperate, adopt the compound needle form to constitute actinobacillus device, promptly by colluding the line pin and the unwrapping wire pin combines actinobacillus device.But there are some shortcomings in existing actinobacillus device.One, collude the line pin and the unwrapping wire pin closely cooperates between the two in order to make, very high to both required precisions, manufacture craft is numerous and diverse, and the processing and manufacturing difficulty is big, the cost height; Two, existing actinobacillus device is in course of action, and the phenomenon of leaking unwrapping wire is more.So, be necessary existing actinobacillus device is improved and innovates, to overcome the above-mentioned shortcoming that exists.

Summary of the invention

The purpose of this utility model be to provide a kind of make simple, with low cost, leak the low Computerized flat knitting machine of unwrapping wire rate and play the actinobacillus device that colludes the line pin in the end.

The technical solution of the utility model is as follows: a kind of computer flat knitting machine plays the actinobacillus device that colludes the line pin in the end, comprise base plate, colluded the line pin, collude line cushion and be loaded on base plate, a unwrapping wire bar and a major axis be arranged in parallel in the braiding flat-bed machine, the major axis two ends fork that respectively is coupling, an end of fork is connected with unwrapping wire bar boom end, and the fork other end is subjected to the cam drive of motor, fork is subjected to cam drive to realize swing, touches travel switch and reaches unwrapping wire.

Described computer flat knitting machine plays the actinobacillus device that colludes the line pin in the end, and fork is herringbone, and the fork end that is connected with the unwrapping wire bar connects a reset tension spring, and fork other end end is a bearing, and end bearing is conflicted by motor-driven cam.

Described computer flat knitting machine plays the actinobacillus device that colludes the line pin in the end, and the line pin that colludes that has been plugged in base plate colludes for shape pin always, and the pin hook surface is smooth.

The pin that colludes the line pin of the present utility model colludes and can catch on the straight line yarn, colludes certain smoothness with hour hands, can make yarn skid off the pin that colludes the line pin under the driving of external force and collude.

The utility model computer flat knitting machine plays the amplitude of oscillation size that the actinobacillus device that colludes the line pin in the end adopts cam mechanism control fork, and left and right fork links to each other by major axis, and unwrapping wire bar two is separately fixed on the left and right fork.Fork is swung by motor-driven, thereby makes the unwrapping wire bar swing to certain position and contact coil, coil is broken away from collude the line pin, reaches the purpose of unwrapping wire; Then, fork resets by extension spring.

The utility model also adopts travel switch to respond to the amplitude of oscillation whether to reach maximum, and promptly all are colluded yarn and all break away from the pins that collude the line pin and colludes.Circuit control panel sends rotating signal to stepper motor, and cooperates induction travel switch feedback signal to move.

The utlity model has that difficulty of processing is low, required precision is low, cost is low, easy and simple to handle, leak the few advantage of unwrapping wire phenomenon.

In the diagram, the secondary roller of 1-, 2-extension spring are colluded, the line pin is colluded in 3-extension spring, 4-major axis, 5-fork, 6-bearing, 7-cam, 8-key, 9-stepper motor, 10-, 11-unwrapping wire bar, 12-coil, 13-braided fabric, 14-master's roller, 15-needle plate, 16-knitting needle, 17-play base plate, 18-inductive switch.

Shown in Fig. 4,5,6, collude line pin 10 and be plugged in base plate 17.Major axis 4 crosses the support (not drawing among the figure) in Computerized flat knitting machine, and major axis 4 is rotatable, and major axis 4 two ends respectively are equipped with fork 5, and fork 5 is herringbone, and the upper end of two forks 5 connects a unwrapping wire bar 11, and unwrapping wire bar 11 is parallel with major axis 4; The upper end of two forks 5 is an end of fixed reset extension spring 3 separately, and the other end of extension spring 3 is fixed in extension spring and colludes 2, and extension spring is colluded 2 and is fixed in support.Wherein bearing 6 is equipped with in the lower end of a fork 5, and a bearing 6 and a cam 7 are conflicted, and cam 7 is connected with the output shaft of stepper motor 9 by key 8, when this fork 5 swings to amplitude peak, touches the inductive head of travel switch 18.

The specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is elaborated.

Shown in Fig. 4,5,6, cam 7 is contained in by key 8 on the output shaft of motor 9, and left and right fork 5 links to each other by major axis 4, and can swing synchronously, and right fork one end is equipped with bearing 6.Unwrapping wire bar 11 two ends are separately fixed on the left and right fork 5, and left and right fork 5 is equipped with reset tension spring 3 respectively, and extension spring 3 one ends are fixed on the fork 5, and the other end is connected in the extension spring of being fixed in support and colludes on 2.Stepper motor 9 startings provide driving force, drive the cam 7 that is connected by key 8 with the output shaft of motor 9, cam 7 is shored the bearing 6 of fork 5 one ends, makes left and right fork 5 swings, collude line pin 10 thereby impel unwrapping wire bar 11 to contact coil 12 smooth disengagings, and with the induction travel switch 8 control amplitudes of oscillation.

Knitting needle 16 takes up one's knitting, the line pin 10 that colludes that has been plugged in base plate rises to the position of catching on coil 12 together with playing base plate 17, and pull down, two main roller 14, the two secondary rollers 1 of this moment all are in separated position, after coil 12 passes two main rollers, 14 engagement places, main roller 14, secondary roller 1 move toward one another, and by separately motor-driven and rotate.Braided fabric 13 has passed through base plate behind 17 good ends, after passing through secondary roller 1 and main roller 14 successively, according to weaving, control system is sent signal to stepper motor 9, stepper motor 9 drives cam 7 work according to the program rotation respective angles of establishment in advance thereby pass through key 8; After cam 7 rotates to an angle, shore the bearing 6 that is contained on the fork 5, cause upwards swing of fork 5; After fork 5 is pressed into induction travel switch 18 probes, be that unwrapping wire bar 11 has reached the maximum amplitude of oscillation, and make collude coil 12 that line pin 3 colluded all break away from collude line pin pin and collude after, inductive switch 18 sends the feedback signal that puts in place to control system immediately, send stop signal by control system to stepper motor 9 again, stepper motor 9 will be received the control system reverse signal immediately then, cause cam 7 no longer bearing 6 to be worked the effect of shoring; Under the restoring force effect of extension spring 3, fork 5 backswings reset unwrapping wire bar 11, finish a setting-out work circulation.The control of stepper motor 9 derives from control system fully, and control system can be sent control signal to stepper motor 9 according to the program of establishment in advance.
