Abstract

Disclosed is a numerical-control pick finding mechanism. A main motor (2) is connected to a loom main shaft (5) through a speed-reducing transmission mechanism (3) and a clutch braking mechanism (4). The loom main shaft (5) drives a warp yarn opening mechanism (7) and a weft yarn selecting mechanism (8) through a transmission part (16). A let-off and take-up signal collection mechanism (14) is disposed on the loom main shaft (5) or a shaft synchronous with the loom main shaft (5). The let-off and take-up signal collection mechanism (14) is separately connected to a take-up mechanism (10) and a let-off mechanism (11) through a control electrical box (1). A pick finding key point signal mechanism (15) is disposed on the loom main shaft (5) or the shaft synchronous with the loom main shaft (5). The pick finding key point signal mechanism (15) is separately connected to the warp yarn opening mechanism (7) and a weft yarn selecting mechanism (8) through the control electrical box (1). The loom main shaft drives, through a synchronous belt, synchronous wheels or chain wheels, a chain or reversing gears and a shaft, the opening mechanism and the selecting mechanism that are controlled by electronic signals. The numerical-control pick finding mechanism has simple structure and stable transmission, and can effectively eliminate wear and reduce maintenance and cost.

Abstract

A weft seeking mechanism of a loom and a weft seeking method. A main motor (2) is connected to a spindle (5) of the loom through a deceleration transmission mechanism (3), a clutch and brake mechanism (4). A warp shedding mechanism (7) controlled via electronic signals and a weft selecting mechanism (8) controlled via electronic signals are driven by the spindle (5) of the loom through a driving member (16). The driving member (16) comprises a synchronous belt and a pulley, or a sprocket and a chain, or a reversing gear and a vertical shaft. A signal acquisition mechanism (14) for numerical-control warp feeding and numerical-control winding is connected to the spindle of the loom or a shaft synchronous with the spindle of the loom, and is connected to a warp feeding mechanism (11) and a winding mechanism (10) respectively through control electrical box (1). A signal generator of a weft seeking key position signaling mechanism (15) is disposed on the spindle of the loom or a shaft synchronous with the spindle of the loom. After a weft fault of the loom occurs, a weft in the loom is broken and the loom is stopped, the mechanism can bring the shedding, weft selecting, warp feeding and winding of the loom back to the weft just broken so as to realize the weft seeking without an uncoupling and re-meshing mechanism.

Abstract

A numerical control rotating cam control fulcrum chute fuzzing mechanism consists of a numerical control fuzzing drive mechanism(3,4,5), a fixed stroke reciprocating mechanism(15,16) and a beating-up slay part(1,2) which is under limiting control by a beating-up drive link (11,13) through a numerical control fuzzing drive mechanism(3,4,5). An electric box(3) of the numerical control fuzzing drive mechanism(3,4,5) drives an eccentric rotating cam (6) through a numerical control motor(4) and a reducing mechanism(5) sequentially, and the eccentric rotating cam (6) carries out drive control on a chute seat with a chute(102) through a push-pull drive mechanism(10,101,9); one end of the beating-up drive link (11,13) is hinged with the fixed stroke reciprocating mechanism(15,16), and the other end of the beating-up drive link(11,13) is movably hinged to a slay sword(1), and the beating-up drive link(11,12) is provided with a sliding block or a rotor (14) which is limited in the chute(102) and slides or rolls along the direction of the chute(102). A conjugate cam group (15)or a crank (21) changes a linear stroke of the beating-up drive link(11,13) when the beating-up drive link(11,13) moves towards the slay sword(1) to a limiting point, so that the slay(2) is stabilized, and beating up can be adjusted to beat weft yarns at different positions of a fell; the mechanism is simple in structure, and is convenient to manufacture and use and can be adjusted to meet different fuzz height requirements at any time.

Abstract

A novel electronic jacquard machine comprises a control electric box (7), a frame (1), an upper electromagnetic selecting and executing component, a lower electromagnetic selecting and executing component, a synchronous reciprocating movement mechanism, a vertical griffe assembly, a suspension wire (205), a harness wire (211) with a hole, a return spring (212) and a fixed plate (4,401). All the electromagnetic selecting and executing components above the cloth fell of the electronic jacquard machine at present are evenly distributed above and below the cloth fell. A connecting rod (503) is driven by the synchronous reciprocating movement mechanism to link the griffe of the corresponding upper and lower electromagnetic selecting and executing components. When the suspension wire (205) passes through a fixed plate (4,401) hole, an inclined angle formed between the suspension wire (205) and the fixed plate (4,401) is controlled to be within an allowable range. The novel electronic jacquard machine can be directly installed in a weaving machine and has the advantages of reasonable structure and stable operation, and the periods for producing, installing and debugging the electronic jacquard machine are greatly shortened. The space requirement on a user is lowered, more convenience is brought for moving the electronic jacquard machine, and a great quantity of manpower, material resources and financial resources can be saved.
