Description

Technical Field

[0001] The utility model relates to the technical field of eccentric beating-up shafts, in particular to a novel eccentric beating-up shaft for a water jet loom. Background Art

[0002] A water jet loom refers to a shuttleless loom that uses a jet of water to pull the weft yarn, allowing the weft yarn to pass through the shed. The function of the eccentric beating-up shaft is to convert the uniform rotation of the water jet loom's main shaft into non-uniform swing, thereby leaving enough time for the weft insertion action. The main structure of the eccentric beating-up shaft includes: main shaft, eccentric shaft, and reed foot. Among them, the role of the eccentric shaft is similar to that of a counterweight. It is relatively laborious when it rotates upward. Therefore, the eccentric beating-up shaft will slow down and stop at this time to ensure that the weft yarn can be inserted into the reed for a sufficient time. On the other hand, for the eccentric beating-up shaft that needs to rotate continuously for a long time, its structural stability is the most important. In other words, the main shaft and the eccentric shaft need to be stably installed, and the reed feet need to be stably installed on the main shaft and the eccentric shaft and not easy to loosen. However, in actual use, the eccentric beating-up shaft still has at least the following two shortcomings, in other words, they are the technical problems to be solved by the present invention: 1. The connection structure between the beating-up shaft body and the counterweight block is too simple, the connection strength is insufficient, and it is relatively easy to have displacement deviation; 2. The structure and installation method of the first reed foot and the second reed foot are completely different, and the two cannot be used interchangeably, which will greatly reduce the practicality of the eccentric beating-up shaft. Therefore, in summary, there is an urgent need for a new type of high-strength eccentric beating-up shaft with a strengthened connection structure between shafts and a unified reed foot style.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN220335411U in the prior art discloses a new eccentric weft shaft for a water jet loom, the structure of which includes a main shaft and an eccentric shaft, and also includes radial holes arranged on the main shaft and the eccentric shaft, a screw block unit arranged on the two radial holes, a positioning groove arranged on the main shaft and the eccentric shaft, and a telescopic reed foot unit arranged on the positioning groove, and a radial hole is respectively provided at both ends of the main shaft and the eccentric shaft.

[0004] Although the above-mentioned existing technical solution can replace the damaged reed foot, the telescopic reed foot unit has its own length adjustment function to ensure that the reed foot structure on the eccentric shaft is also aligned with the segment foot structure on the main shaft. However, when disassembling and replacing each group of reed feet, the staff needs to rotate the bolts and nuts one by one, which is relatively cumbersome and affects work efficiency.

[0025] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the locking assembly includes a movable assembly, a pressing assembly and a clamping assembly.

[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the buckle-pull closing assembly includes an extension groove opened inside the positioning sleeve 4 on one side of the installation groove, a drag groove is opened inside the positioning sleeve 4, a drag rod 16 is installed at one end of the pressing block 12, the drag rod 16 is slidably connected to the drag groove, and a pull ring 17 is installed at one end of the drag rod 16 extending to the inner side of the extension groove, and a closing groove is opened on the outer wall of the positioning sleeve 4 on one side of the extension groove and is interconnected with the closing groove, and a closing plate 18 is slidably connected to the inner side of the closing groove, a buckle-pull groove 3 is opened on one side of the closing plate 18, a sliding groove 19 extending to the inner side of the extension groove is opened on one side of the inner wall of the closing groove, a sliding block slidably connected to the sliding groove 19 is installed at one end of the closing plate 18, and one end of the closing plate 18 and the extension groove are connected. The inner walls are embedded with fixing parts 20, and the two groups of fixing parts 20 are magnetic parts. The magnetism of the two groups of fixing parts 20 is opposite and they attract each other. Furthermore, by buckling the pull ring 17 and pulling it along the inner side of the drag groove, the drag rod 16 drives the clamping block 12 and the limit plate 10 to actively retract. At this time, the reset plate 14 also gradually moves away from the inner side of the positioning groove. Then, by holding the edge of the lap plate 6, you can hold the two sides of the lap plate 6 and pull them apart. When the installation is completed, you can buckle the pull groove 3 to drive the closing plate 18 to cooperate with the sliding groove 19 and the sliding block to approach the inner side of the extension groove until the two groups of fixing parts 20 fit together and absorb the pull ring 17 to cover the inner side of the extension groove to prevent people from accidentally touching it and causing the parts to loosen.

After releasing, it rebounds a distance, and the docking block 7 moves back accordingly. Then the reset plate 14 is against the inner wall of the positioning groove, and the assembly can be completed. When the docking block 7 is aligned with the docking groove in different positions for installation, the position of the reed foot 5 can also be changed accordingly. The pull ring 17 is buckled and pulled along the direction of the inner side of the drag groove, so that the drag rod 16 drives the clamping block 12 and the limit plate 10 to actively retract. At this time, the reset plate 14 also gradually moves away from the inner side of the positioning groove. Then, by holding the edge of the lap plate 6, the two sides of the lap plate 6 can be pulled and separated. When the installation is completed, the buckle groove 3 can be buckled to drive the closing plate 18 to cooperate with the sliding groove 19 and the sliding block to approach the inner side of the extension groove until the two sets of fixing parts 20 are fitted and adsorbed to cover the pull ring 17 on the inner side of the extension groove to prevent people from accidentally touching it and causing the parts to loosen.
