no. 1 Embodiment

[0019] figure 1 It is a structural schematic diagram of the first embodiment of the present invention. The mechanism consists of a bracket 1, a reciprocating heald rod 2, an electromagnet 3, a stopper 4 fixed on the heald rod 2, a reciprocating lifting knife 5, and a sheet elastic body 6 fixed to the lifting knife 5 at one end. , is fixed on the support 1 and consists of a suction device 8; the heald rod 2 and the sheet elastic body 6 are respectively provided with engaging locking devices 2a and 7 that can make the heald rod 2 and the sheet elastic body 6 engage with each other; the support 1 and the sheet elastic body 6 The electromagnet 3 is fixed; the suction aid device 8 is a fixed protrusion, and the surface acting on the sheet elastic body 6 is a curved surface; the iron core of the electromagnet 3 acts on the suction aid device 8 and the sheet elastic body 6 surface.

[0020] This mechanism is under the engaged locking device 2a and 7 engagement state, and when lifti...

no. 2 Embodiment

[0023] Figure 4 It is a structural schematic diagram of the second embodiment of the present invention. This mechanism is except suction device 8, and other structures are identical with the first embodiment; Suction device 8 is made up of slide block 8a, leaf spring 8b, moving block 8c; The other end is fixed on the bracket 1; the slider 8a has a chute, and the sheet elastic body 6 can reciprocate in the chute; the moving block 8c is a reciprocating moving block, and its moving direction is reciprocating with the lifting knife 5 The direction is vertical; the slider 8a and the sheet elastic body 6 are pushed close to the electromagnet 3 by the moving block 8c, and the slider 8a leaves the electromagnet 3 by the elastic restoring force of the sheet spring 8b.

[0024] This mechanism is under the engaged locking device 2a and 7 engagement state, and when lifting knife 5 moves toward suction aid 8 from the limit position farthest away from suction aid 8 (as Figure 5 State sh...

no. 3 Embodiment

[0027] Figure 7 It is a structural schematic diagram of the third embodiment of the present invention. The mechanism is the same as the first embodiment except for the suction device 8; the suction device 8 is a reciprocating moving block whose direction of motion is perpendicular to the reciprocating direction of the lifting knife 5, and he can push the sheet elastic body 6 Attach the solenoid 3.

[0028] This mechanism is under the engaged locking device 2a and 7 engagement state, and when lifting knife 5 moves toward suction aid 8 from the limit position farthest away from suction aid 8 (as Figure 8 State shown), the heald rod 2 and the lifting knife 5 move together, before the lifting knife 5 reaches the limit position close to the suction device 8, first, the heald rod 2 rests on the support 1 through the stopper 4, and the heald rod 2 stops moving , the engagement locking devices 2a and 7 are disengaged from the engagement state, and the deformation of the sheet elas...

Abstract

A heald bar selecting mechanism of jacquard machine is composed of support frame, reciprocating heald bar, electromagnet, stopper fixed to heald bar, reciprocating lifting knife, leaf spring fixed to the lifting knife, and sucking aid. Said heald bar and leaf spring have respectively engage locking unit controlled by electromagnet for allowing the lifting knife to drive heald bar. Its advantages are simple structure, low cost, and high reliability.

Description

technical field [0001] The invention relates to a jacquard machine, in particular to a heald bar selection mechanism of an electronic jacquard machine. Background technique [0002] The heald rod selection mechanism of the electronic jacquard machine is one of the key components of the electronic jacquard machine, which is used to select the warp yarns and control the warp yarns to lift to form openings. [0003] Publication number is that the invention of CN1295143A is a kind of electronic selection mechanism of jacquard machine, and it is made of electromagnet, the movable hook mechanism controlled by electromagnet, the single vertical needle of head band hook and supporting plate. The movable hook mechanism is composed of a base body, a movable hook, a pull rod, an armature, a return spring and the like. Its characteristic is that the traditional jacquard machine blade is replaced by a controllable movable hook mechanism, and the corresponding electromagnet replaces the ...
