Abstract
The utility model discloses a needle turning triangle for a flat knitting machine, which comprises a body, a cylinder and an air channel, wherein the air channel is communicated with the cylinder, a piston is arranged in the cylinder, one end of the piston is fixedly connected with the body, the other end of the piston is connected with the inner wall of the cylinder through a return spring, the cylinder is also provided with a micro switch, and the body is provided with a push rod. In an initial state where the distance between the body and the cylinder is smallest, the push rods triggers the micro switch. The needle turning triangle also comprises a needle-drop prevention triangle and a needle-drop prevention triangle base, wherein the needle-drop prevention triangle base is arranged between the cylinder and the body and is connected with the body through a compressed spring, one end of the needle-drop prevention triangle is fixed on the needle-drop prevention triangle base, the other end of the needle-drop prevention triangle passes through the body. Based on the pneumatic working principle, the influence caused by the magnetic force of an electromagnet can be avoided, the position of the body can be detected through parts such as the micro switch so that the parts can be protected, and the position of the needle-drop prevention triangle relative to the body is unchanged.
Description
Technical field
The utility model relates to technical field of knitting machinery, relates in particular to a kind of flat machine and turns over the pin triangle.
Background technology
Turning over the pin triangle is a vitals in the flat machine system for weaving, and it is installed on the triangle motherboard, mainly acts on when turning over the pin action, and the track that takes the needle is provided for the knitting needle stitch.Adopt magnet control for the motion of turning over the pin triangle at present, but the magnetic force of electromagnet can directly influence the operate as normal of turning over pin trigonometric sum knitting needle to a certain extent.In addition, existingly turn over the device that neither one is suitable on the pin triangle and detect the position of turning over pin triangle body, in the flat machine running, may or leak operation and make and turn over pin triangle body hyperkinesia, cause the damage of fabric and part owing to maloperation.Anti-lost pin triangle is a vitals that turns over the work of pin triangle; It need with turn over pin triangle body and keep relative position constant; Anti-lost pin triangle is normal for directly to be fixed on the body that turns over the pin triangle in the prior art, but this promotes the difficulty of part casting to some extent, has increased cost.
Summary of the invention
The utility model aims to provide a kind of flat machine and turns over the pin triangle, the negative effect that can avoid electromagnet to bring, and can prevent to turn over pin triangle body hyperkinesia, can also locate anti-lost pin triangle easily.
For this reason; The technical scheme that the utility model solves its problem is such: flat machine turns over the pin triangle; Comprise body, cylinder and gas channels, gas channels is communicated with cylinder, and piston is arranged in the cylinder; Piston one end is connected with described body-fixed, and the other end is connected through back-moving spring with cylinder inner wall; Microswitch also is housed on the cylinder, on the described body push rod is housed, under the original state be body and cylinder distance hour push rod trigger microswitch; Turn over the pin triangle and also comprise the anti-lost pin Triangulum of anti-lost pin trigonometric sum, anti-lost pin Triangulum is connected with body through stage clip between cylinder and body, and anti-lost pin triangle one end is fixed on the anti-lost pin Triangulum, and the other end passes body.
In the flat machine running; In the time of need turning over the work of pin triangle; Gas channels to its cylinder in the gas transmission of computer control pneumatic shuttle through turning over the pin triangle of flat machine increases the air pressure in the cylinder, and the piston in the effect lower cylinder of air pressure releases and make back-moving spring generation deformation to produce elastic force; The piston body that will turn over the pin triangle is pushed into the operating position from initial position then, and the push rod on the body leaves microswitch.When turning over the pin triangle when no longer needing work, change the air pressure in the described cylinder through pneumatic shuttle equally, under the effect of back-moving spring elastic force; Piston income cylinder is interior and be with body to reset; After the push rod on the body triggers microswitch once more, promptly get back to initial position, microswitch is passed to the computer of flat machine with this information, and computer obtains controlling pneumatic shuttle at once after this information; Make and turn over the pin triangle and quit work, prevent to turn over the body hyperkinesia part of damage of pin triangle.
In the course of work of turning over the pin triangle, connect cylinder and the anti-lost pin Triangulum of the Trianguli stage clip of anti-lost pin push-tight all the time on the body that turns over the pin triangle, make that to be fixed on the anti-lost pin Triangulum relative position of anti-lost pin triangle and body constant all the time.
The utility model provides a kind of pin triangle that turns over; Through pneumatic principle work, the influence of having avoided electromagnet magnetic force to bring, and detect the guarded by location part of body through parts such as microswitch; The relative position of anti-lost pin triangle and body is remained unchanged, reduced production cost.
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 cutaway view.
The specific embodiment
Referring to accompanying drawing, the body 1 usefulness screw 3 that turns over the pin triangle is fixed on the piston 2, and piston 2 is in the cylinder 4, and piston 2 upper ends link to each other through back-moving spring 5 with cylinder 4 bottoms, and cylinder 4 communicates with gas channels 6.In the time of need turning over the work of pin triangle in the flat machine running, pneumatic shuttle 12 is through gas channels 6 gas transmission in cylinder 4, and air pressure is released piston 2, and meanwhile back-moving spring 5 is compressed, and piston 2 is released the back and driven the body 1 entering operating position of turning over the pin triangle.In the time need not turning over the work of pin triangle, the air pressure that changes in the cylinder 4 through pneumatic shuttle 12 once more, compressed back-moving spring 5 resets piston 2, promptly take in the cylinder 4, thereby the body 1 that is fixed on the piston 2 also is reset.
Cylinder 4 is outer to be equipped with microswitch 7, and push rod 8 also is housed on the body 1, when body 1 and cylinder 4 are nearest; Push rod 8 triggers microswitch 7, and when the body that turns over the pin triangle 1 was pushed to the operating position, push rod 8 left microswitch 7 with body 1 motion; No longer need work when turning over the pin triangle; After body 1 resetted, push rod 8 was drawn close to microswitch 7 once more, until the microswitch 7 that sets out again; The be triggered computer of back flat machine of microswitch 7 is learnt this information, gives an order to make and turns over the pin triangle and stop action to turning over the pin triangle at once.
Anti-lost pin Triangulum 9 is connected with body 1 through two stage clips 10 between cylinder 4 and body 1, and two anti-lost pin triangles 11 are fixed on the anti-lost pin Triangulum 9, and passes body 1 and expose in opposite side.In turning over the pin triangle course of work, no matter how body 1 moves, and two anti-lost pin Triangulums 9 of stage clip 10 push-tight all the time remain unchanged the anti-lost pin triangle 11 of on it two and the relative position of body 1.
