A kind of head of intelligence control jacquard glove machine
Technical field
The present invention relates to computerized glove knitting machine technical field, especially a kind of head of intelligence control jacquard glove machine.
Background technology
Computerized glove knitting machine includes mainly rack (wallboard), needle bed, head and with line mechanism, wherein head is used as compiling
The core component of loom, structure and working method are extremely important.Head is generally made of bottom plate, shell and cam mechanism,
Cam mechanism generally includes lifting triangle, density triangular and depressing cam etc., they are embedded on bottom plate fixed or movablely,
When head is reciprocating on needle bed, the stitch of knitting needle rises or falls along the profile of three corner edges, final collaboration sedimentation
Piece completes the braiding of fabric.
The defect of existing head is:
1) walking mechanism mainly opens up guide groove on guide rail, and angle copper is fixed on head, and angle copper is inserted into guide groove
It guides, prevents from beating during head motion, angle copper should be oriented to the weight for undertaking head again, easy to wear, use
Effect is not so good;
2) spend mesh triangle, purposes be control bearded needle how much eat line, degree mesh triangle push it is deeper, fabric it is more sparse,
Therefore degree mesh triangle is the important component for controlling fabric density degree;In order to adjust fabric density degree, need to spending mesh triangle
Position make corresponding adjusting, existing adjusting method is often the cam in manual adjustment degree mesh triangle drive mechanism, by
Very compact in handpiece structure, it is more inconvenient to adjust, and in the process of running can not adjust automatically degree mesh.
3) needle selecting cam, effect is to select needle-shaped state, for example go out needle length, if goes out needle etc., at work, generally
Coordinate the small triangle of big trigonometric sum to act together and carries out needle selection.The working method of needle selecting cam is at present:Pneumatically play sill strip (also referred to as rubber
Rib, pressed needle-strip) bearing is acted on, bearing is linked by lever mechanism to control the small triangle of needle selecting cam and big trigonometric sum, knot
Structure is more complicated, and intermediate parts are too many, and control is unstable, difficult in maintenance.

2-6 is resisted against the trailing flank of lug boss.The positioning bearing is resisted against the top surface of lower guideway front end.
The operation principle of head walking mechanism is:The cooperation of each adjustable limiting bearing and upper rail, lower guideway, can be to machine
Head is oriented to and is limited, and prevents head motion, positioning bearing from can undertake most of weight of head, reducing abrasion.
As shown in Fig. 4, Fig. 5, Fig. 6, for the defect of existing degree mesh triangle, the improved degree mesh triangle of the present invention regulates and controls machine
Structure, including stepper motor 9-1, worm gear driven by stepper motors 5, the seperated cunning being connect with the rocking arm 3 of worm gear connection, with rocking arm
Resetting spring 9-6 is installed on block 9-8 and the degree mesh triangle 9-7, cam base plate 9-10 that are connect with sliding block, which connects
Then seperated sliding block.
Preferably, the stepper motor is fixed by the first bearing 9-2-1, the second bearing 9-2-2 and positioning plate 9-9
In cam base plate.It is provided with magnetic inductor 9-11 and induction aluminium block 9-12 on stepper motor 9-1, stepper motor 9- can be detected
1 rotational angle (prior art), degree of accurately controlling mesh triangle stroke.
Preferably, the surface of the worm gear offers spiral helicine groove and matches with the output shaft of stepper motor 9-1
The end of the mounting hole 9-5-2 of conjunction, rocking arm 9-3 are inserted by positioning pin 9-4 in groove, the insertion end installation of positioning pin 9-4
There is bearing.
Preferably, the fission sliding block 9-8 is connect after passing through cam base plate 9-10 with degree mesh triangle 9-7.Obviously, triangle
The fluting for allowing seperated sliding block 9-8 to slide is offered on bottom plate 9-10.
Spending the operation principle of the regulating and controlling mechanism of mesh triangle is:When motor drives worm gear rotation, since diameter will not occur for worm gear
To displacement, therefore the positioning pin of rocking arm can only advance along groove, and rocking arm is swung, and pull seperated sliding block, drive degree mesh
Triangle slides, and sets turbine corner size degree of control mesh angular position by the control centre of glove knitting machine, spring pulls seperated sliding
Block ensures that bearing is slided against turbine groove homonymy.
As shown in Fig. 7,8,9, for the defect of existing needle selecting cam, the triangle gear of the improved needle selecting cam of the present invention
Structure, including electromagnet 10-1, by solenoid actuated rocking arm 10-4, driven by rocking arm reset seat 10-7, pass through with reset seat
