Abstract
The present invention relates to a needle selector for a knitting machine, which comprises a needle selecting piece, a connector, a piezoelectric ceramic piece and a fixed plate, wherein a circular through hole is arranged on the rear end of the needle selecting piece, and an elliptical hole is arranged behind the through hole. The shape of the connector is similar to a square frame, the front end of the connector is movably connected with the needle selecting piece, and the rear end of the connector is nested with the piezoelectric ceramic piece. The tail part of the piezoelectric ceramic piece is fixed in a fixed groove of the fixed plate to drive the needle selecting piece to swing up and down, and then, the needle selecting piece can obtain maximal twisting force and a maximal swinging arc; in addition, two groups of piezoelectric ceramic pieces can be clamped on the same fixed plate.
Description
The present invention relates to a kind of modified needle selection device knitting machine.
In the jacquard knitting machine that general jacquard weave circular knitting machine, jacquard weave flatbed knitting machine etc. are used, present stage, system used a kind of driving of knitting needle, conducting jacquard weave program in the memory to the moving up and down of knitting needle, and the effect of formation needle selection.Known needle selection structure is shown in figure one, system is provided with a support 10, establish with a groove 11 in support 10, after making piezoelectrics 12 connect a cylindrical member 13 in its rear end, this cylindrical member 13 is inserted and be fixed in the groove 11 of support 10, piezoelectrics 12 rear ends are moved up or down.The front end of piezoelectrics 12 also is connected in another cylindrical member 13a, and make this cylindrical member be sleeved on the open end 141 of selection piece 14 rear ends, selection piece fixed part 16 then is fixed in axle 15 in selection piece 14 rear ends, and the central authorities of piezoelectrics 12 are inserted in a revolving member 17 and are installed in a middle part 18 of supporting, when piezoelectrics 12 conductions, driven lower swing on the selection piece 14, only these structures are owing to form cylindrical member 13,17 3 fulcrums of 13a and revolving member, therefore, its mechanical energy conversion efficiency is lower, piezoelectrics need bigger relatively, and can't obtain maximum torsion and swinging arc, and are very undesirable.
The design's main purpose is to avoid the shortcoming of above-mentioned needle selection structure, and a kind of novel needle selection device knitting machine is provided, and to improve mechanical switch efficient, makes the needle selection device obtain acrotorque and swinging arc.
Technical scheme of the present invention is, needle selection device knitting machine, comprise selection piece, connector and piezoelectric ceramic piece, directly drive selection piece with piezoelectric ceramic piece, concrete structure is: the selection piece front end is hook-shaped, the rear end is made as fit portion, fit portion the place ahead is provided with open-work, the rear end is provided with an oval perforation, connector by a round bar and the shape frame forms square frame, its front end and selection piece flexible connection, the rear end is nested with the front end of piezoelectric ceramic piece, the piezoelectric ceramic piece rear portion is fixed in the holddown groove of fixed head, and piezoelectric ceramic piece directly drives lower swing on the selection piece, and avoids laterally clashing into the flutter failure piezoelectric ceramics that is produced.
The needle selection device that the present invention is commonly used has following advantage: the one, because the central back partially of piezoelectric ceramic piece fixed-site makes selection piece obtain the torsion and the swinging arc of maximum in fixed head.The 2nd, selection piece and piezoelectric ceramic piece directly link, and make selection piece be able to direct driving, can make mechanical energy conversion efficiency height, and piezoelectric ceramics can be dwindled, and establish two groups of piezoelectric ceramics and can press from both sides on same fixed head.
Fig. 1 is known needle selection device schematic diagram;
Fig. 2 is the three-dimensional appearance schematic diagram of this creation;
Fig. 3 is the perspective exploded view of this creation;
Fig. 4 is the combination schematic diagram of this creation;
Fig. 5 is the generalized section of this creation;
Fig. 6 is the dynamic schematic diagram of this creation.
Below the present invention is elaborated, see also Fig. 2-Fig. 4, this creation mainly comprises a selection piece 2, a connector 3 and in the piezoelectric ceramic piece 4 of sheet metal surface attachment pottery.Wherein, the front end of selection piece 2 is hook-shaped, and its rear end is provided with a circular through-hole 211 for thicker fit portion 21, fit portion front portion, is fixed in framework 6 for latch 210, and fit portion rear is provided with an oval perforation 212.Connector 3 by a round bar and the shape frame forms square frame, the front end of shape frame 31 is provided with being referred to as through hole 311, after round bar 312 passes the elliptical aperture of selection piece 2 rear ends, be fixed in up and down again in the through hole 311 of shape frame 3 front ends, hold nested before set 321 voltage supply electroceramics of the elongated slot sheets 4 in connector 3 rear portions 32.The central authorities of piezoelectric ceramics 4 are the position of back partially, be fixed in fixed head 5, and this fixed head 5 is installed on a framework 6, a location plate washer 61 is established in framework 6 the place aheads, selection piece 2 front ends are stretched in the set locating slot 610 of this plate washer 61, the end of piezoelectric ceramic piece 4 then is connected to the set circuit board 7 in framework 6 rears, with the action of control piezoelectric ceramic piece 4.
By the combination of aforementioned components, this piezoelectric ceramic piece 4 is in when conduction, will drive on the selection piece 2, lower swing, formation needle selection effect.
See also Fig. 5, as shown in the figure, since piezoelectric ceramic piece 4 be with its central authorities partially the fixed-site of back in fixed head 5, constitute single fulcrum, can make selection piece 2 obtain maximum torsion and swinging arc, and owing to selection piece 2 is directly driven by 4 of piezoelectric ceramic pieces, but not drive with indirect lever principle as known, therefore can reach the mechanical energy conversion of high efficiency, and piezoelectric ceramic piece 4 can be dwindled, and can establish two groups of piezoelectric ceramic pieces 4 in same fixedly plate holder.
Shown in Figure 6, by the connected mode of connector 3 with selection piece 2, piezoelectric ceramic piece 4, can make piezoelectric ceramic piece 4 fully directly drive following, the lower swing of selection piece 2, and its laterally bump strength can absorb by the iron plate 61 around the selection piece 2, can avoid laterally clashing into the vibration that is produced and destroy piezoelectric ceramics.
