Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following detailed description is made with reference to the accompanying drawings and specific embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many other forms than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the one element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a single embodiment.
For the purpose of clear explanation of the technical solution, the reasons for the prior art defects are explained in detail: in the open-gear adjusting mechanism of the warp knitting machine in the prior art, as shown in fig. 1, the top end of a connecting rod 1 directly passes through a guide hole of a guide arm 2 and then is hinged with an upper bracket 3. The knockover plate 6 takes a first fulcrum a1 as a rotation center in an adjustment process, the latch needle 5 takes a second fulcrum a2 as a rotation center in an adjustment process, a connecting line between the top end of the knockover plate 6 and the first fulcrum a1 is a first connecting line b1, a connecting line between the top end of the latch needle 5 and the second fulcrum a2 is a second connecting line b2, an activity in the top end adjustment process of the knockover plate 6 corresponds to the first path c1, an activity in the top end adjustment process of the latch needle 5 corresponds to the second path c2, the second fulcrum a2 is close to the top end of the connecting rod 1 and is located on one side of the first fulcrum a1, because an included angle between the first connecting line b1 and the second connecting line b2 is large, the deviation between the first path c1 and the second path c2 is large, when the knockover plate 6 performs position adjustment on the fabric thickness, the top end of the knockover plate 6 moves on the first path c1, in the process, the top end of the latch needle 5 can follow the movement of the knockover plate 6 to perform the same movement along the second path c2, the same adjustment, the position of the latch needle can immediately perform repeated operation, and the repeated operation of the latch needle can cause the change of the split plate 5, and the operation area is small, and the operation is troublesome operation is required.
The top of the connecting rod 1 is hinged with a connecting piece 7, and the hinged position realizes a hinged structure through a transverse through hole and a horizontal pivot shaft. The top of the connecting piece 7 is connected with a bracket 3 through a bolt, the bracket 3 has the bearing function, the needle bed 4 is fixedly assembled at the upper end of the bracket 3, the needle bed 4 is positioned at the inner side of the top of the bracket 3 and extends inwards, and the latch needle 5 is assembled at the top of the end of the inner side of the needle bed 4.
A knock-over plate 6 is provided inside the latch needle 5, and the tip of the latch needle 5 abuts against the tip of the knock-over plate 6.
The bottom of the knocking-over plate 6 is hinged with a guide arm 2, and the hinged position realizes a hinged structure through a transverse through hole and a horizontal pivot shaft. The bottom of the guide arm 2 extends towards the outside, a guide hole of a longitudinal through hole structure is formed in the guide arm 2, the connecting piece 7 is of a rod body structure, the connecting piece 7 penetrates through the guide hole longitudinally and can slide up and down in the guide hole, and the guide hole plays a role in guiding and restraining. Because the assembly relationship of the guide hole and the linking piece 7 also forms a linkage structure of the latch needle 5 and the knockover plate 6, when the position of the knockover plate 6 and the guide arm 2 is adjusted, an assembly body formed by the linking piece 7, the bracket 3, the needle bed 4 and the latch needle 5 is driven to synchronously move, and the existing structure just causes deviation of the relative position relationship of the knockover plate 6 and the latch needle 5 after the knockover plate 6 is adjusted, so that the latch needle 5 needs to be further adjusted.
The hinged position of the knocking-over plate 6 and the inner side end of the guide arm 2 is represented as a first supporting point a1 of the knocking-over plate 6 for adjusting the center of the moving path, the bottom of the connecting piece 7 below the guide hole is provided with a bending part 71, the bending part 71 is bent and extended inwards, so that the bottom end of the connecting piece 7 is deviated to the inner side, the hinged point of the connecting piece 7 and the connecting rod 1 is located on the bending part 71, the hinged position is represented as a third supporting point a3 of the latch needle 5 for adjusting the center of the moving path, a connecting line between the top end of the latch needle 5 and the third supporting point a3 is a third connecting line b3, the third connecting line b3 is close to the first connecting line b1, and an included angle between the first supporting point and the third supporting point is smaller than 5 degrees. The moving path of the latch needle 5 along the third fulcrum a3 is a third path c3, and the third path c3 is basically overlapped with the first path c1 in the station area. When the latch needle 5 moves in the station area along with the adjustment action of the knockover plate 6, the relative position of the latch needle and the knockover plate is basically kept still, so that the machine can be started to operate without correcting and adjusting the height and the angle of the latch needle 5 again after the thickness of the yarn is adjusted by the knockover plate 6.
Fig. 3 shows a specific assembling state between the open-stage adjusting mechanism 200 and the warp knitting machine frame 100.
On the basis of the technical scheme, a hinged structure is formed between the bottom of the knockover plate 6 and the inner side end of the guide arm 2 through a transverse through hole and a pivot shaft, and the pivot shaft between the knockover plate 6 and the guide arm 2 is parallel to the pivot shaft between the connecting piece 7 and the connecting rod 1.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced: such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
