Description
技术领域technical field
本实用新型属于纺织机械技术领域,涉及一种多剑杆分别控制的伸缩剑杆引纬机构。The utility model belongs to the technical field of textile machinery and relates to a telescopic rapier weft insertion mechanism controlled separately by multiple rapiers.
背景技术Background technique
三维机织物是纤维增强复合材料中性能较为优良的增强材料,它使纤维在三维空间中沿着多个方向分布并相互交织在一起形成不分层的整体结构,具有良好的整体性、层间性、仿形性等优点,将其作为增强相制备而成的复合材料,在航空航天、国防军工、交通运输、建材、能源等领域有着广泛地应用。Three-dimensional woven fabric is a reinforcing material with relatively good performance in fiber-reinforced composite materials. It makes fibers distribute along multiple directions in three-dimensional space and interweaves with each other to form a non-layered overall structure. It has good integrity and interlayer The composite materials prepared by using it as a reinforcing phase have the advantages of high stability and profiling, and are widely used in aerospace, national defense, transportation, building materials, energy and other fields.
三维机织物通常是由多层经纱与多根纬纱交织而成的,每一次织造循环过程中需要形成多个梭口,引入多根纬纱。可实现多剑杆引纬的机构较多,如空间连杆引纬机构、导杆引纬机构、直线电机和连杆组合装置,这几种引纬方式的剑杆都安装在剑杆箱中,每个剑杆的运动同步,便于对剑杆的运动规律进行控制,但同时也限制了可织造织物组织的复杂化。为此,设计了齿轮—连杆组合引纬装置,该装置上每个剑杆由单独的伺服电机控制,即安装几个剑杆就能产生几种不同的运动轨迹,但是该机构在织造幅宽较大的织物时,又存在剑杆刚度较差,影响送纬剑和接纬剑交接的问题,还有送纬剑和接纬剑退剑后占用空间较大等问题。因此,需要发明一种多个剑杆可以分别控制,且在工作过程中又可以较好的保证剑杆刚度的伸缩剑杆引纬机构。Three-dimensional woven fabrics are usually interwoven with multiple layers of warp yarns and multiple weft yarns. In each weaving cycle, multiple sheds need to be formed and multiple weft yarns must be introduced. There are many mechanisms that can realize multi-rapier weft insertion, such as space connecting rod weft insertion mechanism, guide rod weft insertion mechanism, linear motor and connecting rod combination device. The rapiers of these weft insertion methods are all installed in the rapier box , the movement of each rapier is synchronized, which facilitates the control of the movement law of the rapier, but also limits the complexity of the weavable fabric structure. For this reason, a gear-connecting rod combination weft insertion device is designed. Each rapier on the device is controlled by a separate servo motor, that is, several different motion trajectories can be produced by installing several rapiers. For larger fabrics, there are problems such as poor rapier stiffness, which affects the handover of the weft sending sword and weft receiving sword, and the weft sending sword and weft receiving sword take up a lot of space after the sword is retracted. Therefore, it is necessary to invent a telescopic rapier weft insertion mechanism that can control a plurality of rapiers separately and can better ensure the rigidity of the rapiers during the working process.

本实用新型一种多剑杆分别控制的伸缩剑杆引纬机构中单个引纬机构的工作原理如下:伺服电机3转动时驱动齿轮轴b7转动,齿轮轴b7进而将驱动力矩传递给齿轮b6,齿轮b6带动与其相啮合的齿轮a4转动,齿轮a4转动时,驱使与齿轮a4以铰链连接的连杆a8运动,连杆a8运动时,驱动齿轮c14运动,齿轮c14一方面相对于固定齿条13转动,另一方面驱使活动齿条12沿箱体第二部分2-2顶面上的导槽a9移动,移动时带动固接在其上的支架a18、支架b19运动,支架a18、支架b19运动时带动剑杆1相对剑杆19移动。连杆8驱动齿轮c14运动的同时还会带动滑块11沿着导槽b19及导槽c16往复运动,滑块11的运动对齿轮c14起到导向作用,保证其沿直线运动而不会偏移,滑块11运动的同时通过支架c21带动剑杆b17作往复运动,由于剑杆1是由活动齿条12驱动,剑杆b17通过滑块11驱动,活动齿条12的速度是滑块11速度的2倍,因此在运动过程中剑杆a1的动程是剑杆b17的两倍,并且剑杆b17在运动过程中其两端分别由剑杆支架c21和支架d22支撑,所以剑杆a1在运动时和剑杆b17接触的部分刚度较好,也相对的减小了剑杆a1伸出部分的长度。实质上剑杆a1作为引纬剑,剑杆b17为提高剑杆a1的刚度只起辅助作用。The working principle of a single weft insertion mechanism in a telescopic rapier weft insertion mechanism controlled by multiple rapiers in the utility model is as follows: when the servo motor 3 rotates, the gear shaft b7 is driven to rotate, and the gear shaft b7 then transmits the driving torque to the gear b6, The gear b6 drives the gear a4 meshed with it to rotate. When the gear a4 rotates, it drives the connecting rod a8 hinged with the gear a4 to move. When the connecting rod a8 moves, the driving gear c14 moves. Rotation, on the other hand drives the movable rack 12 to move along the guide groove a9 on the top surface of the second part 2-2 of the box body. When moving, it drives the bracket a18 and bracket b19 fixedly connected thereto to move, and the bracket a18 and bracket b19 move When driving rapier 1 relative rapier 19 moves. When the connecting rod 8 drives the gear c14 to move, it will also drive the slider 11 to reciprocate along the guide groove b19 and the guide groove c16. The movement of the slider 11 plays a guiding role on the gear c14, ensuring that it moves along a straight line without deviation , while the slider 11 is moving, the bracket c21 drives the rapier b17 to reciprocate. Since the rapier 1 is driven by the movable rack 12, and the rapier b17 is driven by the slider 11, the speed of the movable rack 12 is the speed of the slider 11. 2 times of rapier a1, so the stroke of rapier a1 is twice that of rapier b17 during movement, and the two ends of rapier b17 are supported by rapier bracket c21 and bracket d22 respectively during movement, so rapier a1 is in The rigidity of the part in contact with the rapier b17 during movement is relatively good, and the length of the protruding part of the rapier a1 is relatively reduced. In essence, the rapier a1 is used as a weft insertion sword, and the rapier b17 only plays an auxiliary role in order to improve the rigidity of the rapier a1.
本实用新型一种多剑杆分别控制的伸缩剑杆引纬机构的特点为,每个剑杆引纬机构作为一个独立的运动单元,运动互不影响,多个独立的运动单元通过一系列的连接与装配构成多剑杆引纬机构。提高了织造效率同时满足了剑杆动程较大时所需的刚度。The utility model is characterized in that a telescopic rapier weft insertion mechanism controlled separately by multiple rapiers is that each rapier weft insertion mechanism acts as an independent motion unit, and the motion does not affect each other, and multiple independent motion units pass through a series of The connection and assembly constitute a multi-rapier weft insertion mechanism. It improves the weaving efficiency and at the same time satisfies the required rigidity when the rapier stroke is large.
