Description
技术领域 technical field
本发明涉及一种有结渔网机上钩针摆动机构，属于水产用品技术领域。 The invention relates to a hook hook swing mechanism on a knotted fishing net machine, which belongs to the technical field of aquatic products.
背景技术 Background technique
网状织物分为有结型和无结型，分别适用于不同的使用场合。如果要求结构比较稳定，如捕鱼用网、水产养殖用网箱等，一般使用有结型网状织物。在建筑工程中用安全网、其它场合用遮阳网等，一般采用无结网状织物。无结网状织物一般通过少梳栉经编机编织，有结网状织物一般利用有结渔网编织机进行编织。为了实现编织有结网状织物，在有结型渔网编织机中，上钩针的运动是整机的核心运动，其作用是，对织网经线进行打结。对于上钩针而言，其运动包括运动形式和运动大小两方面的要求。在运动形式上，要求上钩针作绕定点的摆动运动；运动大小又包括两方面，一是摆动角度幅度的大小，二是摆动过程中运动位移的变化规律要求，摆动角度幅度大小通过连杆机构或者凸轮机构都可以实现。而现有技术的上钩针运动采用一般的连杆机构对经线打结比较单一，同时经常因上钩针摆动不到位或运动位移量不够，从而导致上钩针运动对经线进行打结过程中容易造成打结不牢靠或不能有效完成打结，使结出的渔网质量较差，须进行渔网网结的修复，从而加大了操作工人的劳动强度，降低了整机的工作效率。 Mesh fabrics are divided into knotted and knotless, which are suitable for different occasions. If the structure is required to be relatively stable, such as fishing nets, cages for aquaculture, etc., knotted mesh fabrics are generally used. Knotless mesh fabrics are generally used for safety nets in construction projects and sunshade nets for other occasions. Knotless mesh fabrics are generally woven by warp knitting machines with few bars, and knotted mesh fabrics are generally woven by knotted fishing net knitting machines. In order to realize the weaving of knotted net-like fabrics, in the knotted fishing net knitting machine, the movement of the upper crochet needle is the core movement of the whole machine, and its function is to knot the warp threads of the net. For crochet needles, its movement includes the requirements of both the form of movement and the size of the movement. In terms of movement form, the crochet needle is required to perform a swinging movement around a fixed point; the size of the movement includes two aspects, one is the size of the swing angle range, and the other is the change rule of the movement displacement during the swing process. The swing angle range is determined by the linkage mechanism. Or a cam mechanism can be realized. However, the upper crochet needle movement of the prior art adopts a general linkage mechanism to knot the warp thread, and it is often caused by the upper crochet needle not swinging in place or the movement displacement is not enough, thus causing the upper crochet needle movement to easily cause knotting during the warp thread knotting process. The knot is not firm or can not be effectively completed, so that the quality of the resulting fishing net is relatively poor, and the fishing net knot must be repaired, thereby increasing the labor intensity of the operator and reducing the working efficiency of the whole machine.

Above-mentioned crochet needle 7-3 is provided with a plurality of pieces according to the breadth width of woven fishing net, is arranged in sequence on the upper crochet needle bed 7-2, and is installed side by side along the machine length direction.
本发明的有结渔网机上钩针摆动机构，工作过程如下： The crochet swing mechanism on the knotted fishing net machine of the present invention works as follows:
轴A0由电机驱动，其上固装有主动齿轮1,带动与之啮合的从动齿轮2转动。在从动齿轮2的轮体上加工有沟槽凸轮3，其中，3-1是外轮廓线，3-2是内轮廓线。主动齿轮1由电机经过带传动减速后驱动，沟槽凸轮3（外轮廓线3-1和内轮廓线3-2）的结构在从动齿轮2轮体上，形成一整体一起绕主轴B0上的固定支点转动。 The shaft A0 is driven by a motor, on which the driving gear 1 is fixed, and drives the driven gear 2 meshed with it to rotate. Grooved cam 3 is processed on the wheel body of driven gear 2, wherein, 3-1 is the outer contour line, and 3-2 is the inner contour line. The driving gear 1 is driven by the motor after being decelerated by the belt transmission, and the structure of the grooved cam 3 (outer contour line 3-1 and inner contour line 3-2) is formed on the wheel body of the driven gear 2 to form a whole and wind around the main shaft B0 together. The fixed fulcrum rotates.
第二滚子6置于沟槽凸轮3的3-1和3-2形成的沟槽中，第二滚子6的直径与沟槽的宽度相同，第二滚子6的中心与导杆5在C铰接点通过转动副铰接。当沟槽凸轮3随从动齿轮2一起转动时，驱动凸轮机构从动件即导杆5作直线移动。由于第二滚子6与导杆5在C点是通过转动副铰接，所以，第二滚子6与沟槽凸轮3的内、外轮廓线（3-1和3-2）之间是滚动摩擦。由于第一滚子4空套在主轴B0上，与主轴作不同步转动，因此在导杆5上下往复直线移动时，第一滚子4与导杆5的框形结构（5-1）也是滚动摩擦。 Second roller 6 is placed in the groove that 3-1 and 3-2 of grooved cam 3 form, and the diameter of second roller 6 is identical with the width of groove, and the center of second roller 6 and guide bar 5 At the hinge point C, it is hinged by a revolving joint. When the grooved cam 3 rotates with the driven gear 2, the cam mechanism follower, that is, the guide rod 5, is driven to move linearly. Since the second roller 6 and the guide rod 5 are hinged at point C through a rotating pair, there is a rolling motion between the second roller 6 and the inner and outer contour lines (3-1 and 3-2) of the grooved cam 3. friction. Since the first roller 4 is vacantly sleeved on the main shaft B0 and rotates asynchronously with the main shaft, when the guide rod 5 reciprocates linearly up and down, the frame structure (5-1) of the first roller 4 and the guide rod 5 Also rolling friction.
导杆5在其两端点中间具有框形结构（5-1），框形结构（5-1）的宽度与第一滚子4的直径相同，安装时，第一滚子4置于导杆5的框形结构（5-1）内，也即导杆5的框形结构（5-1）套在第一滚子4上。第一滚子4的中心空套安装在主轴B0上，即与主轴不同步转动。这样的结构使得导杆5一方面可以随着第一滚子4绕B0轴摆动，同时，又使导杆5通过B0点作上下往复直线移动。导杆5的一端与连架杆7-1在D1点以转动副相连，连架杆7-1绕上钩针针床摆动轴D0摆动。当导杆5在沟槽凸轮3的驱动下作往复直线移动时，驱动连架杆7-1往复摆动。连架杆7-1固定安装在上钩针针床摆动轴D0上，当连架杆7-1摆动时，上钩针针床摆动轴D0随之摆动。连架杆7-1 与上钩针针床7-2为一整体，一起绕D0轴上的固定支点点摆动。上钩针7-3固定安装在上钩针针床7-2上，并随上钩针针床7-2和连架杆7-1一起摆动。 The guide rod 5 has a frame-shaped structure (5-1) in the middle of its two ends, and the width of the frame-shaped structure (5-1) is the same as the diameter of the first roller 4. When installing, the first roller 4 is placed on the guide rod 5 within the frame structure (5-1), that is, the frame structure (5-1) of the guide rod 5 is sleeved on the first roller 4. The central empty sleeve of the first roller 4 is installed on the main shaft B0, that is, it rotates asynchronously with the main shaft. Such a structure enables the guide rod 5 to swing around the B0 axis along with the first roller 4 on the one hand, and at the same time, makes the guide rod 5 reciprocate linearly up and down through the B0 point. One end of the guide rod 5 is connected with the link bar 7-1 at point D1 with a revolving pair, and the link bar 7-1 swings around the swing axis D0 of the crochet needle bed. When the guide rod 5 moves linearly back and forth under the drive of the grooved cam 3, the connecting frame rod 7-1 is driven to swing back and forth. The connecting frame bar 7-1 is fixedly installed on the swing axis D0 of the upper crochet needle bed, and when the connecting frame bar 7-1 swings, the upper crochet needle bed swing axis D0 swings thereupon. Linkage bar 7-1 is an integral body with upper crochet needle bed 7-2, swings around the fixed fulcrum point on the D0 axis together. The upper crochet needle 7-3 is fixedly installed on the upper crochet needle bed 7-2, and swings together with the upper crochet needle bed 7-2 and the connecting frame bar 7-1.
