Description
Technical field
The invention belongs to footwear machine field, specifically a kind of clear needle link mechanism of footwear machine.
Background technique
In existing footwear machine head knitting member, it is typically provided needle driving lever, clear needle driving lever and crochet needle and links, and
Needle driving lever and clear needle driving lever are driven equipped with electromagnet.Solenoid actuated needs electric wire to connect power supply, in actual production process
In, it is easy to appear the case where electromagnet connection electric wire is broken, seriously affects the normal work of footwear machine.Meanwhile electromagnet can only
It is enough controlled, is controlled more coarse by switching electricity.Also, electromagnetic actuation and reset need the regular hour, cause
The braiding speed of crochet needle is restricted.In addition, electromagnet is easy to be influenced and break down by electric current, magnetic field, it is electric when serious
Magnet can not work, and need additionally to replace electromagnet and clear out a gathering place to surrounding enviroment, and maintenance cost is high, maintenance difficulty is big.
Summary of the invention
For overcome the deficiencies in the prior art, connected the present invention provides a kind of using the clear needle of footwear machine of mechanical linkage connection
Linkage, structure is simple, easy to assembly, stable structure, can effectively reduce using various failures caused by solenoid actuated, mention
The stability and the speed of service of high footwear machine operation.
To achieve the above object, the clear needle link mechanism of footwear machine uses the skill similar with needle link mechanism in the present invention
Art scheme, it is specific as follows: including clear needle driving lever, to be equipped with clear needle connecting rod, Islamic control block, degree mesh adjusting block and Islamic control-rod.
The both ends of clear needle connecting rod movably connects with clear needle driving lever, clear needle control block respectively and to form revolute pair, the clear needle control block other end and
Clear needle control lever one end clearance fit setting.Spending mesh adjusting block one end, also the splaying is equipped with clear needle control lever.It is described
Clear needle control lever is formed by connecting by 2 branch rod bearings, which is combined with a bearing control bar, and bearing control bar and one use
In the stepper motor connection that control bearing control-rod moves reciprocatingly.In the other end of the clear needle control lever, clear needle driving lever
Portion is rotatably pinpointed on bottom plate or bracket.
Preferably, being connected with torsional spring between the shaft and the clear needle control lever end of the degree mesh adjusting block.
Preferably, forming the lesser side angle of angle between described two struts is interior arc angle, other side angle is
Outer arc angle, bearing outer arc angle side and bearing control bar clearance fit in the same plane.
Preferably, being connected with tension spring between the shaft of degree mesh adjusting block and the shaft of clear needle control block.
Preferably, the bearing control bar and needle link mechanism share i.e. the bearing control bar and needle connecting rod machine
The bearing control bar of structure can be controlled simultaneously by a stepper motor by bearing control bar for that can be the same bearing control bar
Needle link mechanism, clear needle link mechanism carry out needle movement or the movement of clear needle, needle link mechanism and clear needle link mechanism knot
Structure is similar, but function complements one another.
Beneficial effects of the present invention are as follows: one, the present invention replaces the prior art using link mechanism in conjunction with stepper motor
Middle solenoid actuated mode, linkage arrangement is light and handy, small in size, and both easy to produce, assembling also significantly reduces head braiding
The weight of component entirety keeps the operation of head knitting member more flexible.Also, link mechanism generally mechanical structure, design
Accurately, structural stability is good, can be reduced failure problems caused by solenoid actuated, improves the operation stability of footwear machine.Even
The running speed and operating frequency of linkage compared to solenoid actuated mode faster, it is more stable, be conducive to improve footwear machine
Knit socks speed and efficiency.In addition, stepper motor stability and accuracy are high, convenient for control, the miniature of footwear machine maincenter can be passed through
Processing controller directly controls.
Two, clear needle control lever passes through time difference while degree of stirring mesh adjusting block in clear needle link mechanism provided by the present invention
With clear needle control block, mesh will be spent adjusts the driving structure that acts with clear needle and be combined into one, it is the smart structural design, stable,
Simplify the operating procedure of knitting member and the size of knitting member.And structure is simplified, knitting member weight has been reduced, makes
Knitting member is more convenient for processing and be repaired, while also reducing production cost and maintenance maintenance expense, is conducive to improve warp
Ji benefit.
