Abstract
The utility model relates to a beating-up mechanism of a jet looms, which comprises a rockshaft, a plurality of lathe swords which are distributed along the axial direction of the rockshaft at intervals and are fixed on the rockshaft, a sley fixed on the lathe swords and a reed fixed on the sley. A steel wire is connected between two adjacent lathe swords, and each steel wire is provided with at least a damping vibration absorber. When the vibration of the reed is transmitted to the lathe swords, the steel wire can make motion along with the vibration of the lathe swords. The damping vibration absorber can absorb the vibration of the lathe swords, thereby causing the beating-up mechanism of the jet looms to have better vibration absorbing ability.
Description
Technical field
The utility model relates to the beating-up mechanism on a kind of air-jet loom.
Background technology
Along with improving constantly of air-jet loom rotating speed, the vibration that beating-up mechanism produces is also more and more stronger.The workpiece reed of beating-up mechanism is subjected to the reaction force of weft yarn in the course of the work, be subjected to the active force of assistant nozzle air current again, these power all are changeable on time and space, so being produced, reed has destructive vibration, these vibrations pass to lay sword by slay, lay sword is delivered to rocker again, and rocker also can produce complicated bending vibration in reciprocal swing.So beating-up mechanism vibrates normal in service can the generation, influences the stable operation of loom, and beating-up mechanism is damaged, and influences its service life, can't satisfy the requirement of the more and more higher air-jet loom of rotating speed to absorbing.
Summary of the invention
The purpose of this utility model is to provide a kind of air-jet loom beating mechanism with better vibration absorption ability.
In order to reach above purpose, the technical scheme that the utility model adopted is:
A kind of air-jet loom beating mechanism, comprise rocker, distribute and be fixed on several lay swords on the described rocker, be fixed on slay on the described lay sword, be fixed on the reed on the described slay along the axially spaced-apart of described rocker, be connected with steel wire between the described adjacent lay sword, described every steel wire is provided with at least one damping dashpot.
Described damping dashpot comprises the damping rubber circle that is enclosed within on the described steel wire, the clamping device that is used to clamp described rubber ring.
The weight of described clamping device is greater than 0.1kg.
Described clamping device is two semicircle pressure rings, and described two semicircle pressure rings are by the bolt relative fixed and clamp described damping rubber circle.
Owing to adopted above technical scheme, so the utlity model has following advantage: be connected with steel wire between the adjacent lay sword, and all be provided with at least one damping dashpot on the every steel wire, when the vibration of reed is transmitted lay sword by slay, steel wire can move along with the vibration of lay sword, be arranged on can the decay vibration of lay sword of damping dashpot on the steel wire, make this air-jet loom beating mechanism have vibration absorption ability preferably.
Description of drawings
Accompanying drawing 2 is the front view of damping dashpot in the utility model air-jet loom beating mechanism;
Accompanying drawing 3 is the side view of damping dashpot in the utility model air-jet loom beating mechanism;
Accompanying drawing 4 is the structural representation of restriction damping layer on the rocker in the utility model air-jet loom beating mechanism.
Wherein: 1, rocker; 2, restriction damping layer, 3, reed; 4, damping dashpot; 5, steel wire; 6, lay sword; 7, slay; 21, damping layer; 22, restraint layer; 41, semicircle pressure ring, 42, damping rubber circle.
The specific embodiment
As shown in Figure 1, a kind of air-jet loom beating mechanism, comprise and rotatablely be arranged on rocker 1 on the air-jet loom, distribute and be fixed on several lay swords 6 on the rocker 1, be fixed on slay 7 on the lay sword 6, be arranged on the reed 3 on the slay 7 along the axially spaced-apart of rocker 1, in order to have vibration absorption ability preferably, the utility model air-jet loom beating mechanism is connected with steel wire 5 between adjacent lay sword 6, every steel wire 5 is provided with at least one damping dashpot 4.
Clamping device in the present embodiment is a semicircle pressure ring 41, two semicircle pressure rings 41 are by four bolt relative fixed and clamp damping rubber circle 42, by the compaction that bolt can be regulated damping rubber, change the elastic constant of damping rubber, allow damping dynamic damper 4 be in effective duty.
In the work, reed 3 beat up and the wefting insertion process in produce vibration, these vibrations are delivered to lay sword 6 by slay 7, steel wire 5 can move along with the vibration of lay sword 6, damping rubber circle 42 in the damping dashpot 4 can produce frictional damping to steel wire 5, weaken the motion of steel wire 5, and because two semicircle pressure rings 41 of clamping damping rubber circle 42 have certain weight, so can consume the energy of steel wire 5 vibrations, absorb the vibration of lay sword 6, make this air-jet loom beating mechanism have vibration absorption ability preferably.
Steel wire 5 and damping dashpot 4 can absorb vibration more on the lay sword 6, but still can some vibration transfer arrive rocker 1, rocker 1 itself also can produce the bending vibration, so on rocker 1, be coated with restriction damping layer 2 in the present embodiment, this restriction damping layer 2 comprises the damping layer 21 that is adjacent on described rocker 1, covers the restraint layer 22 on the damping layer 21, as shown in Figure 4, wherein damping layer 21 is made by epoxy resin, and restraint layer 22 is made by aluminium or steel plate.For the ease of installing, this restriction damping layer 2 is a semi-cylindrical shape, and two restriction damping layers 2 are coated on the circumference of rocker 1 relatively.In order to reach result of use preferably, this restriction damping layer 2 is coated near the rocker 1 stressed complicated both ends of the surface.Restriction damping layer 2 can make rocker 1 decay to stable status in the short period of time when vibration takes place, and makes this air-jet loom beating mechanism have higher vibration absorption ability.
