Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, and particularly relates to a knitting machine heart buffer structure with better stability. Background Technique

[0002] As is well known, the knitting mechanism of a knitting machine refers to the heavy components on the knitting machine used to achieve knitting operations, belonging to the "heart components" of the knitting machine. They play a crucial role and affect the performance of the knitting machine and the quality of the fabric.

[0003] The utility model patent with the publication number of CN219972622U discloses a single-sided knitting circular machine heart structure, and its structure includes: a fixed base, and a plurality of saddle seats annularly distributed on the fixed base. The saddle seat includes an installation part for fixing triangular blocks and a fixing part connected to the fixed base. Through the combination of the first convex ring, the second convex ring, the pressing plate, and the driving ring, when the saddle seat is installed, the fixing part of the saddle seat is radially limited by the first convex ring and the second convex ring. At the same time, after the driving ring drives the pressing plate to slide to the top of the fixing part, the up-and-down limitation of the fixing part is completed. When it needs to be disassembled and replaced, the driving ring is rotated reversely to reset, prompting the pressing plate to separate from the top of the fixing part, and then each saddle seat can be taken out upward for replacement. Therefore, when assembling the saddle seat or disassembling and replacing saddle seats of different models, the operation is simple, and the installation and replacement speed of the saddle seat can be effectively improved, shortening the maintenance time of the single-sided circular machine heart structure.

[0004] However, the existing knitting machine heart structure still has certain deficiencies: First, although the existing knitting machine heart structure is fixed by bolts, due to the influence of factors such as vibration, the vibration deflection phenomenon of the bolts will occur after long-term use, and then the installation stability of the knitting disk is weak.

Through the setting of the first spring 7, the telescopic block 6 can be connected and used.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , a buffer mechanism 8 is arranged inside the support leg 2. The buffer mechanism 8 includes a guide rod 81. A guide rod 81 is fixedly connected to the vertical part of each support leg 2. A slider 82 is slidably sleeved on the outside of the guide rod 81. The slider 82 is fixedly connected to the knitting disk 1. A second spring 83 is arranged on the outside of the guide rod 81. A damping hole 84 is opened in the vertical part of the support leg 2. A guide plate 85 is fixedly connected to the inside of the slider 82. A top plate 86 is slidably sleeved on the outside of the guide plate 85. The top plate 86 is slidably connected to the slider 82. An elastic member 87 is bonded to the end face of the top plate 86 on the side away from the damping hole 84. The other end of the elastic member 87 is bonded to the slider 82. A damping rod 88 is fixedly connected to the end face of the top plate 86 on the side close to the damping hole 84. The damping rod 88 is slidably connected to the damping hole 84. Through the deformation of the second spring 83, the vibration generated by the knitting disk 1 can be buffered. Under the structures such as the damping hole 84 and the damping rod 88, the excess deformation stress generated by the second spring 83 can be frictionally dissipated, avoiding the problem that the second spring 83 drives the knitting disk 1 to have excessive jitter.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , an elastic damping block is fixedly connected to the inside of the slider 82. The elastic damping block is slidably connected to the vertical part of the support leg 2. Through the setting of the elastic damping block, the friction dissipation effect on the deformation stress of the second spring 83 can be improved. One end of the second spring 83 is welded to the slider 82. The other end of the second spring 83 is welded to the vertical part of the support leg 2. Through the setting of the second spring 83, the slider 82 can be supported and used. A plurality of damping holes 84 are provided.

Through the setting of the damping holes 84, it is convenient to cooperate with the damping rod 88 for mutual frictional dissipation use.

[0027] The specific implementation process of the present utility model is as follows: During use, by pulling the end plate 4 upward, the square block 5 is driven to move, and the telescopic block 6 is driven to slide along the inner wall of the horizontal part of the support leg 2. The first spring 7 deforms, and finally the telescopic block 6 is far away from the horizontal part of the support leg 2. Then, the bolt 3 is pushed through the horizontal part of the support leg 2 so that the bolt 3 contacts the installation member of the knitting machine. The bolt 3 is rotated to make the bolt 3 perform a threaded movement, the bolt 3 is fixed, and the end plate 4 is released so that the first spring 7 restores its deformation, pulling the end plate 4 into contact with the bolt 3 and driving the square block 5 to insert into the bolt 3 to limit the bolt 3 and avoid the problem of vibration deflection of the bolt 3, so as to ensure the high stability of the connection of the knitting disc 1;

[0028] When the knitting disc 1 vibrates, the slider 82 can be driven to move along the surface of the guide rod 81, and the second spring 83 deforms to buffer and release the vibration generated by the knitting disc 1. During this process, when the slider 82 moves, the top plate 86 can be driven to move, and then the damping rod 88 is driven to move. Under the extrusion of the inner wall of the damping hole 84, the damping rod 88 can be pushed to move, driving the top plate 86 to slide along the inner wall of the slider 82, and the elastic member 87 deforms. Finally, the damping rod 88 is separated from the damping hole 84. Under the action of force, the damping rod 88 slides along the vertical part of the support leg 2. When the damping rod 88 slides into the next damping hole 84, the elastic member 87 restores its deformation to push the damping rod 88 into the damping hole 84. This process repeats. With the cooperation of structures such as the damping hole 84 and the damping rod 88, the excess deformation stress generated by the second spring 83 can be frictionally dissipated, avoiding the problem of excessive jitter of the knitting disc 1 driven by the second spring 83.
