Abstract
The utility model discloses a needle pushing device for a flat knitting machine. The needle pushing device comprises needle pushing triangles, a needle pushing connection rod and a shaft pin, wherein connection shafts are fixed below the needle pushing triangles; a pin hole is formed in each connection shaft; a plurality of through slots are formed on the needle pushing connection rod; and the shaft pin passes through the pin holes in the connection shafts and the through slots on the needle pushing connection rod, so that each through slot is matched with each needle pushing triangle and each connection shaft. The structure of the flat knitting machine is simplified, so that the needle pushing triangles are easily and precisely matched, and the operation load of a flat knitting machine computer is reduced.
Description
Technical field
The utility model relates to technical field of knitting machinery, relates in particular to a kind of flat machine needle pushing-up device.
Background technology
Needle pushing-up device is one of core institution in the flat machine, and it is arranged in head, comprises parts such as the triangle of pushing pin; Effect is to promote the needle selection that the needle selection device is selected; Be installed in motherboard on needle selection under protect the mountain and cooperate, needle selection is pushed to turns over the pin position, thereby get into the braiding circulation.Because the demand of braiding, the triangle of pushing pin need move up and down between operating position and rest position, switching continually, and adjacent two triangles of pushing pin have only one to be in the operating position.
In the existing flat machine, each triangle of pushing pin all needs one to overlap independently that drive unit moves up and down to control it, need controlled the drive unit of each triangle of pushing pin separately and each triangle of pushing pin is cooperatively interacted by the flat machine computer; The flat machine complex structure of this pattern, big to the computational load of computer, the programming difficulty is high; Cooperate and be prone to make mistakes; The triangle of pushing pin is not easy the location, and the energy that a plurality of thrust units consume is many, and production cost is higher.
Summary of the invention
The utility model aims to provide a kind of flat machine needle pushing-up device, can make a plurality of triangle interlocks of pushing pin wherein.
For this reason, the technical scheme that the utility model adopted is such: the flat machine needle pushing-up device, comprise the triangle of pushing pin, and be fixed with connecting axle under the triangle of pushing pin, have a pin-and-hole on the connecting axle; Also comprise the connecting rod of pushing pin, the connecting rod of pushing pin is provided with some grooves; Also comprise pivot pin, pivot pin passes the groove of the pin-and-hole on the connecting axle and the connecting rod of pushing pin, and each groove is matched with push pin triangle and a connecting axle.
As the further technical scheme of the utility model, described groove is " Z " shape groove that the turning point forms the obtuse angle.
As the further technical scheme of the utility model, " Z " shape groove on adjacent two said connecting rods of pushing pin in the opposite direction.
The utility model is when work; Push pin connecting rod under the driving of drive unit; Do not produce relative displacement longitudinally with protecting mountain products to give birth to horizontal relative displacement under the needle selection; Push pin triangle and connect and to protect the mountain under connecting axle and pivot pin and the needle selection on it and do not produce horizontal relative displacement, and can protect mountain products life relative displacement longitudinally under the control of the connecting rod of pushing pin and under the needle selection.
" Z " shape groove cooperates with the pivot pin of connecting axle; Be pivot pin and the moving track of the connecting rod relative displacement of pushing pin; Pivot pin is moving back and forth between the top section of " Z " shape groove and end section under the control of " Z " groove; Formation moves up and down, and switches between operating position and rest position thereby drive the triangle of pushing pin.
Each adjacent " Z " shape groove is in the opposite direction, makes adjacent two triangles of pushing pin in that the direction of motion is always opposite longitudinally, thereby makes adjacent two triangles of pushing pin have only one to be in the operating position.
Because control pivot pin; I.e. control pushes pin that triangle moves up and down just connects " Z " shape groove top section and end section oblique section; After the top section or end section of pivot pin by oblique section entering " Z " shape groove; The connecting rod even push pin is because the inertia of drive unit when continuing to produce horizontal micro-displacement with unstability, and pivot pin can't be moved, thus the stablizing of the triangle that keeps pushing pin.
The utility model has been simplified the structure of flat machine; Only need a drive unit can drive all the triangle interlocks of pushing pin in the whole needle pushing-up device; Cut down the consumption of energy; And the cooperation that each is pushed pin between triangle is simple and easy accurately, has alleviated the computational load to the flat machine computer, thereby has improved the performance of flat machine.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model sketch map.
Fig. 2 is the utility model rearview.
Fig. 3 is for protecting the sketch map that mountain and motherboard cooperate under the utility model and the needle selection.
The specific embodiment
Referring to accompanying drawing, push pin triangle T1, T2, T3, T4 and be installed in and protect mountain 3 under the needle selection on the motherboard 5 and cooperatively interact in the needle pushing-up device are fixed with connecting axle 4 respectively under each triangle of pushing pin, and all have a pin-and-hole on each connecting axle.Needle pushing-up device also comprises the connecting rod 1 of pushing pin; The connecting rod 1 of pushing pin is provided with " Z " shape groove C1, C2, C3, the C4 that the turning point forms the obtuse angle; Match with push pin triangle and a connecting axle respectively through pivot pin 2, wherein groove C1, C3 and groove C2, C4's is in the opposite direction.
In the flat machine running; The connecting rod 1 of pushing pin is protecting the mountain 3 horizontal relative displacements of generation and is not producing relative displacement longitudinally under the driving of drive unit with under the needle selection; Push pin and protect the mountain under triangle T1, T2, T3, T4 and connecting axle 4 and pivot pin 2 and the needle selection and do not produce horizontal relative displacement, and can be the control of the connecting rod of pushing pin under and protect mountain 3 under the needle selection and produce relative displacement longitudinally.
Be as the criterion with main perspective, when pushing pin connecting rod 1 when protecting mountain 3 to left movement under the needle selection, to the rest position motion, the triangle T2 that pushes pin, T4 are moved to the operating position by groove C2, C4 control by groove C1, C3 control for the triangle T1 that pushes pin, T3; Otherwise when pushing pin connecting rod 1 when protecting mountain 3 under the needle selection and move right, to the operating position motion, the triangle T2 that pushes pin, T4 are moved to rest position by groove C2, C4 control by groove C1, C3 control for the triangle T1 that pushes pin, T3.
After pivot pin 2 pushes up section or end section by the oblique section entering of groove C1, C2, C3, C4; Connecting rod 1 continues the certain displacement of generation because of the reaction of inertia or drive unit is untimely even push pin; Pivot pin 2 can not produce displacement in the vertical, thereby makes each triangle of pushing pin keep stable.
