Description
Technical field
The utility model is related to technical field of knitting machinery, specifically a kind of preforming device with auto-lock function.
Background technology
Cross machine triangulo system generally has three row pressure faller gills, i.e., do not knit tabletting, braiding tabletting, barring-on tuck tabletting.Wherein,
Braiding tabletting is used to coordinate needle selecting cam and slide cam selector to carry out push action to the needle-selecting and sticking sheet piece heel on needle-bar together, so that
Perform needle motion.In actual production process, vibration, the collision of flat-knitting machine head easily make braiding tabletting produce misoperation, cause
The braiding tabletting 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.
Utility model content
The utility model provides a kind of preforming device with auto-lock function.
The purpose of this utility model is that vibration, the collision for solving flat-knitting machine head easily make braiding tabletting produce misoperation, is caused
The braiding tabletting that should be raised position is changed into settling phase, causes knitting needle to enter woven condition, ultimately results in weaving textile mistake
The problem of losing or produce serious weaving mistake.
The utility model solves the technical scheme that its technical problem used：A kind of tabletting dress with auto-lock function
Put, including sliding block tabletting, it also includes crank, connecting rod, rocking bar, and the head of the crank is provided with crank rotational axis hole, the song
The afterbody of handle 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, institute
State and rocker pivot axis hole is provided with the middle part of rocking bar, machine is fixed in the crank rotational axis hole and rocker pivot axis hole by short axle respectively
Head, the sliding block tabletting front portion is in strip, and the afterbody of the sliding block tabletting is inclined-plane, and the inclined-plane is provided with one and sliding block
Anterior 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 utility model are：Preforming device described in the utility model with auto-lock function utilizes four bars
Mechanism produces dead point phenomenon and causes crank and connecting rod to keep coUinear state in the case where being acted on without external force, and preforming device is pinned, makes it
Tabletting is not set to produce misoperation because of the vibration of head, collision, it is to avoid weaving textile failure or to produce serious weaving wrong
By mistake the problems such as.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 top view.
Fig. 3 is Fig. 1 side view.
Fig. 4 is the structural representation of sliding block tabletting.
Fig. 5 is Fig. 4 side view.
Fig. 6 is the structural representation of rocking bar.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
There is the embodiment of the preforming device of auto-lock function, including sliding block tabletting there is provided the utility model as shown in the figure
7, it also includes crank 2, connecting rod 4, rocking bar 5, and the head of the crank 2 is provided with crank rotational axis hole 1, the afterbody of the crank 2
It is flexibly connected with the head of connecting rod 4 by short axle 3, the afterbody of connecting rod 4 is flexibly connected with the head of rocking bar 5 by short axle, described to shake
The middle part of bar 5 is provided with rocker pivot axis hole 6, and machine is fixed in the crank rotational axis hole 1 and rocker pivot axis hole 6 by short axle respectively
Head, the front portion of sliding block tabletting 7 7c is in strip, and the afterbody 7b of the sliding block tabletting is inclined-plane, and the inclined-plane 7b is provided with one
The individual and groove 7a of sliding block front portion 7c at an angle, the afterbody of 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 tabletting 7, which is in stretching state, i.e. preforming device, is 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 tabletting 7
7c produces a counter-force, but is due to that now crank 2 is in coUinear state with connecting rod 4, and four-bar mechanism produces dead point phenomenon, crank
2 will not move with connecting rod 4 and continue to keep coUinear state.Only when having, external force acts on crank 2 and on 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 groove 7a bearing of trend and sliding block front portion 7c are at an angle, sliding block tabletting 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 described in the utility model with auto-lock function produces dead point phenomenon using four-bar mechanism and causes song
Handle and connecting rod keep coUinear state in the case where being acted on without external force, and preforming device is pinned, and it is not made because of the vibration of head, collision
Tabletting produces misoperation, it is to avoid weaving textile failure or the problems such as produce serious weaving mistake.
