Abstract
The utility model discloses a computer flat knitting machine including a needle bar mechanism including a die head having quantity-unlimited needle selector, a needle bar having a quantity-unlimited needle selecting unit. The utility model is characterized by that each said needle selecting unit has a needle selecting gear standing out of the needle bar surface, each said needle selector has a needle pressing mechanism acting on said needle selecting gear, said needle selecting mechanism may swing in positive and reverse direction by transmission of controlled motor. The utility model replaces controlling six stitches of a set of needle selector with six pieces of electro-magnet by controlling a needle selection presser, then the needle selector is simplified, five kinds of needle selecting foot, circuit control is simplified, veracity of operation is more possible, consistency of action is ensured, produce efficiency and work quality are improved and operation is more convenient.
Description
Technical field
The utility model relates to the controlled flat knitting machine field of computer control.
Background technology
Controlled flat knitting machine is knitting field a kind of machinery commonly used, and it comprises needle-bar mechanism, driving mechanism, cloth-winding mechanism etc., and wherein needle-bar mechanism is a critical component, comprises head, cam system and needle selection device.Drive electromagnet when head moves, and pass through the action transmission of driving mechanism, control the advance and retreat of needle selection device, thereby reach the purpose of needle selection.As shown in Figures 1 and 2,1 is the needle selection device, and 11 is needle selection device presser feet, and 2 is six sections stitch, and 3 is inserted sheet, and 4 are the pin of being hit by a bullet.Along with head moves, to lift on six sections stitch 2, needle selection device presser feet 11 is if be in the A position, and presser feet presses down, and this moment, six sections stitch 2 were in non-selected state; When under the needle selection device presser feet 1 be in shown in the dotted line the B position time, presser feet is not pressed on six sections stitch 2, these six sections stitch 2 are in chosen state, stitch is higher than the surface of inserted sheet 3, the pin 4 that promotes then to be hit by a bullet, and finish follow-up needle selection and braid movement.Each stitch must be respectively by a magnet control, in common two-shipper head system, the needle selection device has 8 groups, and every group has 6 grades of stitch difference one corresponding to the needle selection tooth, therefore need with 8 * 6 totally 48 magnet control, the action that is difficult to reach each grade of working simultaneously of a plurality of electromagnet all acts in agreement.The reaction time of electromagnet is 5～8 microseconds, and the reaction time is difficult to satisfy fully work requirements.Structurally, exist the pin number many, assembly complexity, the deficiency that maintenance cost is high.Needle selection electromagnet volume is little, and for preventing the overheated 12V of employing Control of Voltage, and other electric elements adopt 24V voltage more, therefore on control circuit, has two kinds of control of 12V and 24V voltage, so that the control procedure complexity, controls cost and increases.
Summary of the invention
The purpose of this utility model is to provide a kind of simplified selecting mechanism, easy to operate, computer plain flat knitter that operating accuracy is high.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of computer plain flat knitter, comprise needle-bar mechanism, and needle-bar mechanism comprises head, is provided with the needle selection device that does not limit quantity; And needle-bar, be provided with the needle selection unit that does not limit quantity, it is characterized in that: each described needle selection unit is provided with a needle selection tooth that protrudes in the needle-bar surface; Every group of described needle selection device is provided with a presser, acts on described needle selection tooth, and described presser can be done forward and reverse swing by the transmission of pulse controllable motor.
Specifically, described pulse controllable motor can be stepper motor or servomotor.
The utility model is done forward and reverse swing with driving pressers such as stepper motor or servomotors, controls the selected of knitting needle.Because can reaching 1 to 2 millisecond, the reaction speed of pulse motor changes a fixed angle, thereby can control a needle selection presser feet by a pulse controllable motor, replaced 6 blocks of electromagnet to control 6 grades of stitch in one group of needle selection device respectively, simplified the needle selection device, reduced by five kinds of needle selecting foots, simplified circuit control, more can realize the accuracy of operating, improved production efficiency and work quality, made more convenient operation.The pulse of needle selection device motor positive and inverse is controlled with the main pulse control that drives servomotor and can be guaranteed by a controller, reaches accurate needle selection requirement, the uniformity of energy safety action.
Description of drawings
Fig. 1 is existing needle selection device and six sections stitch action schematic diagrames.
Fig. 2 is the structural representations of six sections stitch of prior art when chosen.
Fig. 3 is head and needle-bar partial side view.
Fig. 4 is presser of the present utility model and needle selection tooth action schematic diagram.
The specific embodiment
Computer plain flat knitter of the present utility model comprises knitting mechanism, driving mechanism, cloth-winding mechanism etc.As shown in Figure 3, head 6 before and after correspondence is provided with respectively on the front and back needle-bar 5, the needle selection device is arranged on the Triangulum panel of head 6, and the quantity of needle selection device does not limit, and transforms according to existing controlled flat knitting machine, and 8 groups of needle selection devices can be set.
As shown in Figure 4, each needle selection device 7 is provided with a presser feet 71, and presser feet 71 is articulated in the output shaft of pulse controllable motor 8, and its presser feet acts on the needle selection tooth 91 of needle selection unit 9.Needle selection unit 9 is arranged on the needle-bar, and its quantity does not limit, and needle selection tooth 91 protrudes in the needle-bar surface.When the motor step actuator received a pulse signal, presser feet 71 was subjected to the control of pulse controllable motor 8, can do forward and reverse swing, swung a fixed angle (as being 1.8 ° integral multiple), and reaction speed can reach 1 to 2 millisecond.When presser feet 71 was in illustrated A position, presser feet promoted needle selection tooth 91, and this moment, the needle selection unit was in non-selected state; When presser feet 71 was rocked to the B position, presser feet left needle selection tooth 91, and this moment, the needle selection unit was in selected state, protruded in the needle-bar surface, thereby chosen.
The concrete shape and the connected mode of needle selection device 7 are not limited to shown in the accompanying drawing, as long as structurally can satisfy the output transmission of pulse controllable motor.
Claims (3)
1, a kind of computer plain flat knitter comprises needle-bar mechanism, and needle-bar mechanism comprises head, is provided with the needle selection device that does not limit quantity; And needle-bar, be provided with the needle selection unit that does not limit quantity, it is characterized in that: each described needle selection unit is provided with a needle selection tooth that protrudes in the needle-bar surface; Every group of described needle selection device is provided with a presser, acts on described needle selection tooth, and described presser can be done forward and reverse swing by the transmission of pulse controllable motor.
