Description
Technical field
The present invention relates to technical field of knitting machinery, specifically a kind of preforming device with auto-lock function.
Technical background
Cross machine triangulo system generally has three row pressure faller gills, i.e., do not knit compressing tablet, braiding compressing tablet, barring-on tuck compressing tablet.Wherein,
Braiding compressing tablet carries out push action for coordinating needle selecting cam and slide cam selector to be called in person to the needle-selecting and sticking sheet piece on needle-bar together, so that
Perform needle motion.In actual production process, the vibration of flat-knitting machine head, collision easily make braiding compressing tablet produce misoperation, cause
The braiding compressing tablet that should be raised position is changed into settling phase, causes knitting needle to enter woven condition, ultimately results in weaving textile mistake
Lose or produce serious weaving mistake.
The content of the invention
The invention provides a kind of preforming device with auto-lock function.
Vibration, collision present invention aim to address flat-knitting machine head easily make braiding compressing tablet produce misoperation, and causing should
For the braiding compressing tablet of raised position is changed into settling phase, cause knitting needle to enter woven condition, ultimately result in weaving textile failure or
Produce the problem of serious weaving mistake.
The technical solution adopted for the present invention to solve the technical problems is：A kind of preforming device with auto-lock function, bag
Sliding block compressing tablet is included, it also includes crank, connecting rod, rocking bar, the head of the crank is provided with crank rotational axis hole, the tail of the crank
Portion is flexibly connected with link rod head by short axle, and the connecting rod afterbody is flexibly connected with rocking bar head by short axle, the rocking bar
Middle part is provided with rocker pivot axis hole, and head is fixed in the crank rotational axis hole and rocker pivot axis hole by short axle respectively, institute
State sliding block compressing tablet anterior in strip, the afterbody of the sliding block compressing tablet is inclined-plane, and the inclined-plane is provided with one with sliding block front portion
Groove at an angle, the rocking bar afterbody is placed in groove.
Further, the head of the rocking bar and afterbody form right angle shape, the rocking bar tail end are in spherical shape.
The beneficial effects of the invention are as follows：Preforming device with auto-lock function of the present invention is produced using four-bar mechanism
Dead point phenomenon causes that crank and connecting rod keep coUinear state in the case where being acted on without external force, and preforming device is pinned, and makes it not because of head
Vibration, collision and compressing tablet is produced misoperation, it is to avoid weaving textile failure or the problems such as produce serious weaving mistake.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
As shown in the figure, there is provided the embodiment of preforming device of the present invention with auto-lock function, including sliding block compressing tablet 7, it
Also include crank 2, connecting rod 4, rocking bar 5, the head of the crank 2 is provided with crank rotational axis hole 1, the afterbody of the crank 2 and company
The head of bar 4 is flexibly connected by short axle 3, and the afterbody of the connecting rod 4 is flexibly connected with the head of rocking bar 5 by short axle, in the rocking bar 5
Portion is provided with rocker pivot axis hole 6, and head is fixed in the crank rotational axis hole 1 and rocker pivot axis hole 6 by short axle respectively, institute
The front portion of sliding block compressing tablet 7 7c is stated in strip, the afterbody 7b of the sliding block compressing tablet is inclined-plane, and the inclined-plane 7b is provided with one and slides
Block front portion 7c groove 7a at an angle, the afterbody of the rocking bar 5 is placed in groove 7a.
The head 5a and afterbody 5d form right angle shapes of the rocking bar 5, the rocking bar tail end 5e are in spherical shape.
Its operation principle is：When sliding block compressing tablet 7 is in stretches out state, i.e. preforming device in raised position, sliding block pressure
The front portion of piece 7 7c will produce pressing effect to the heel of needle-selecting and sticking sheet piece, while the heel of needle-selecting and sticking sheet piece also can be anterior to sliding block compressing tablet 7
7c produces a counter-force, but because now crank 2 and connecting rod 4 are in coUinear state, four-bar mechanism generation dead point phenomenon, crank
2 will not move with connecting rod 4 and continue to keep coUinear state.Only when there is external force to act on crank 2 and connecting rod 4, destruction is bent
When handle 2 is with 4 collinear relationship of connecting rod, crank 2 and connecting rod 4 can just produce relative motion, so as to drive rocking bar tail end 5e to exist
Slided in groove 7a, because the bearing of trend of groove 7a is at an angle with sliding block front portion 7c, sliding block compressing tablet 7 will be with rocking bar 5
Swing and it is movable perpendicular to head planar delta, complete the conversion between preforming device raised position and settling phase.
Preforming device with auto-lock function of the present invention using four-bar mechanism produce dead point phenomenon cause crank and
Connecting rod keeps coUinear state in the case where being acted on without external force, and preforming device is pinned, and it is not made compressing tablet because of the vibration of head, collision
Produce misoperation, it is to avoid weaving textile failure or the problems such as produce serious weaving mistake.
