Description
技术领域technical field
本实用新型涉及一种织机,具体说是一种喷气织机打纬箱体。The utility model relates to a loom, in particular to a beating-up box of an air jet loom.
背景技术Background technique
喷气织机主轴是360度匀速旋转,而打纬钢筘既要在引纬时有足够的停顿时间来让气流吹着纬纱在喷气异形筘气槽里飞行到头,又需要在引纬实现后将纬纱快速而有力的打到织机0度最前端交织点上。离打纬点最远位置停顿时间越长则用于引纬的时间越充足,对引纬的气压要求相应越低,同时车速也就可以更快;打纬力越大,则织机织造的布面风格越饱满,同时对厚重品种适应范围更广。The main shaft of the air-jet loom rotates at a constant speed of 360 degrees, and the beating-up reed should not only have enough pause time during weft insertion to allow the airflow to blow the weft yarn to the end in the air groove of the air-jet special-shaped reed, but also need to be inserted after the weft insertion. The weft yarn is quickly and powerfully hit to the frontmost interweaving point at 0 degrees on the loom. The longer the pause time is at the farthest position from the beating-up point, the more time is used for weft insertion, the lower the air pressure requirements for weft insertion, and the faster the vehicle speed; the greater the beating-up force, the more The fuller the cloth style, the wider the range of adaptation to heavy varieties.
现有280cm门幅机器正常运转在550转/分钟以内的喷气织机基本采用的偏心曲柄通过六联杆或四联杆驱动打纬轴上的筘座脚、筘座和钢筘来解决引纬所需停顿时间的,缺点是近似停顿时间最长不超过60度,而且停顿时间长了,打纬时间越短且力越小。机器运转速度提不上去,也不能织厚重织物,且因为偏心曲柄上的联杆是通过轴瓦在曲柄上旋转是滑动摩擦,所以轴瓦材质要求高,时间长了会磨损,更换麻烦,能耗高,打纬力小,易损件多,维修量大。申请号201110088652.1喷气织机的公开内容是概要的介绍了共轭凸轮打纬作为喷气织机的一种打纬方式及其优点,没有具体的可行的实施结构方案,从其申请资料的图中可以看出那是一个不可行的方案,没有解决共轭凸轮间隙调整问题,而且从所示附图中摆轴朝大齿轮方向的转子是对应了离大盖板远的一个凸轮片上,为了与过桥大齿轮不干涉,则摆轴需要外移,整个箱体会更大,产生对其他零部件的干涉。另一个转子是对应了离大盖板近的凸轮片上,再加上结合凸轮片的形状,此结构不科学且不能可行的实现喷气打纬和引纬。Existing 280cm door width machines normally operate within 550 r/min. The eccentric crank basically uses the eccentric crank to drive the reed seat foot, reed seat and steel reed on the beating shaft through six or four links to solve the problem of weft insertion. The disadvantage of the required pause time is that the approximate pause time does not exceed 60 degrees at the longest, and the longer the pause time is, the shorter the beating time and the smaller the force. The running speed of the machine cannot be increased, and heavy fabrics cannot be woven, and because the connecting rod on the eccentric crank rotates on the crank through the bearing bush, it is a sliding friction, so the material requirements of the bearing bush are high, and it will wear out over time, which is troublesome to replace and high energy consumption. , The beating force is small, the wearing parts are many, and the maintenance volume is large. The disclosure content of the application number 201110088652.1 of the air-jet loom is a general introduction of the conjugate cam beating-up method and its advantages as a beating-up method of the air-jet loom. There is no specific feasible implementation structure scheme. It can be seen that it is an unfeasible solution, and the problem of adjusting the gap of the conjugate cam is not solved, and the rotor with the pendulum shaft facing the direction of the large gear corresponds to a cam sheet far from the large cover in the shown figure. If the bridge gear does not interfere, the pendulum shaft needs to be moved outward, and the entire box will be larger, resulting in interference with other components. The other rotor is corresponding to the cam piece close to the large cover plate, and combined with the shape of the cam piece, this structure is unscientific and cannot be used to realize jet beating and weft insertion.

The cam rotor gap is adjustable and Air-jet loom beating-up box that does not interfere with other parts of the loom.
