Dual conjugated cams are adopted, the two ends of the rotating shaft are connected with the two gear shafts respectively, the gear shafts and the beating-up shaft are in transmission connection with the conjugated cams through the transmission gears, an accurate moving rule is achieved, after a box base is matched with the mechanism, the angular acceleration of the box base is the maximum in beating-up, inertia beating-up is achieved, and movement of the box base can be freely controlled; compared with the prior art, the dual-conjugated-cam beating-up mechanism has the advantages that loom vibration can be reduced, and the beating-up force is larger than that of a four-bar linkage mechanism for beating-up.
Description
Technical field
The utility model relates to textile processing equipment technical field, particularly a kind of biconjugate Cam Beating-up Mechanism mechanism for loom.
Background technology
Weft yarn is introduced after the shed open of loom, for by introducing, the weft yarn of shed open is pushed fell to and warp thread is intertwined to form the fabric that meets designing requirement, must weft yarn be pushed to fell by specialized agency, this mechanism is called as beating-up mechanism, it is to affect a very important mechanism of loom characteristic, is directly connected to high speed, the vibratility etc. of loom.The loom of prior art adopts the four connecting rods assembly that beats up, comprise bent axle, crank, lead along by hand and slay composition, drive motion hand in hand by crankshaft rotating through crank, thereby driving the reed being fixed on slay to realize beats up, but this equipment moving rule is not accurate enough, the dynamics of beating up is less, and loom vibration is also less.
Utility model content
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of biconjugate Cam Beating-up Mechanism mechanism for loom, can strengthen the dynamics of beating up, and guarantees that frame is steady, improves the degree of accuracy of the reed characteristics of motion.
For achieving the above object, the utility model proposes a kind of biconjugate Cam Beating-up Mechanism mechanism for loom, comprise slay, tightening weft axis and rotating shaft, described slay is connected on tightening weft axis through bearing, on slay, be provided with reed, the two ends of described rotating shaft are all connected with tooth axle, described tooth axle top is provided with travelling gear, described travelling gear is engaged on the groove place of tooth axle, on travelling gear, be connected with conjugate cam, the two ends of described tightening weft axis are connected with the balance staff corresponding with travelling gear, and described balance staff is connected with travelling gear.
As preferably, on tightening weft axis, be connected with hold-down support.
As preferably, the axial line of described tightening weft axis, rotating shaft, tooth axle, balance staff is and is parallel to each other.
As preferably, the below of described tightening weft axis is provided with balancing weight, and described balancing weight is connected with bearing.
As preferably, the longitudinal length summation of described balancing weight is less than the longitudinal length of tightening weft axis.
The beneficial effects of the utility model: the utility model adopts biconjugate cam, connect two tooth axles by the two ends in rotating shaft, tooth axle and tightening weft axis are realized and being in transmission connection by travelling gear and conjugate cam, realize the characteristics of motion accurately, coordinate after block, block angular acceleration maximum while beating up, realize inertial beating-up, the motion of block can be controlled arbitrarily, compared with prior art, the utlity model has and can reduce loom vibration, beating-up force is than the four connecting rods large advantage of beating up.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
Accompanying drawing explanation
