[0002] With the continuous advancement of modern loom technology, the expansion of the range of high-end fabrics weaved by water jet looms, and the development of automation and high speed, the coordination between various loom mechanisms needs to be further strengthened, achieving higher precision, more sensitive response, and more accurate results. Mechanical warp let-off mechanisms no longer meet high-performance requirements, and electronic warp let-off mechanisms are increasingly being used in water jet looms. Existing electronic warp let-off mechanisms generally use non-electrical measurement methods to collect warp tension signals. These signals are processed electronically or using microcomputer technology to control and regulate a separate motor, driving the weaving beam to deliver the warp yarn and maintaining constant warp tension. Electronic warp let-off mechanisms typically consist of a motor, a gear reducer, a tension signal acquisition system, and a control system. In existing gearboxes, both the input gear and the intermediate gear are helical gears. The motor shaft passes through an end cap to connect to the input gear, which is then engaged with the intermediate gear. The meshing process between the two helical gears is cumbersome, reducing efficiency. Furthermore, the outer end of the motor shaft is connected to the input gear via a locking nut, which can lead to unstable operation.

The assembly is used to unlock the lock between the box body 1 and the installation cover 2, and the protective assembly is used to protect the operating parts of the dragging assembly. When in use, the device can lock and connect the box body 1 and the installation cover 2 by resetting the locking assembly. The dragging assembly unlocks the lock between the box body 1 and the installation cover 2, and the protective assembly protects the operating parts of the dragging assembly. It has a simple structure and is easy to operate, which makes it convenient for the staff to quickly disassemble and assemble the box body 1 and the installation cover 2. The disassembly and assembly can be completed by just pressing and twisting, which reduces the workload of the staff and improves work efficiency.

[0024] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the reset locking assembly includes a docking block 6 installed on one side of the lap plate 4, and a docking groove is provided at one end of the connecting seat 5, and the docking groove and the docking block 6 are slidably connected. A locking groove is provided on one side of the docking groove inside the connecting seat 5, and a limited seat 7 is installed on one side of the inner wall of the locking groove. The top of the limit seat 7 is overlapped with a bonding plate 8, and the rubber pad 20 is provided with a docking hole at the docking block 6. The docking block 6 and the docking hole are slidably connected. A limited groove is provided on the top of the limit seat 7, and the inner side of the limit groove is slidably connected to the limited block 9. One end of the limit block 9 is fixedly connected to one side of the bonding plate 8, and a first spring 10 is installed between one side of the limit block 9 and the inner wall of the limit groove, and a stretching groove is provided on one side of the bonding plate 8, and a second spring 19 is installed between the inner wall of the stretching groove and the inner wall of the locking groove. First, overlap the box body 1 and the mounting cover 2, so that the connecting seat 5 overlaps the rubber pad 20, so that a part of the docking block 6 enters the inner side of the docking groove, and continues to squeeze the lap plate 4 to allow the rubber pad 20 to retract.

[0025] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the opposite ends of the docking block 6 and the bonding plate 8 are provided with inclined surfaces that fit together, and the interior of the bonding plate 8 is provided with a rotation groove at its inclined surface. The inner side of the rotation groove is rotatably connected with a rotating rod, and an abutment plate 11 is sleeved on the outer side of the rotating rod. One side of the abutment plate 11 is provided with a slope that fits the inclined surface, and a torsion spring 12 is installed between the rotating rod and the inner wall of the rotating groove. The interior of the docking block 6 is provided with an abutment groove at its inclined surface. Then, the docking block 6 gradually moves down and abuts against the inclined surface on the bonding plate 8, forcing the bonding plate 8 to drive the limit block 9 in the limit position. The first spring 10 and the second spring 19 are stretched while the docking block 6 slides inside the groove, squeezing the first spring 10 and stretching the second spring 19. As the docking block 6 continues to descend, it contacts the abutment plate 11 and forces the rotating rod to rotate. The torsion spring 12 retracts until the abutment groove is close to the rotating groove. The abutment plate 11 is ejected to the inside of the abutment groove by the torsion spring 12, and then no longer squeezes the lap plate 4, causing the rubber pad 20 to rebound a short distance. The docking block 6 also moves a short distance, allowing one end of the abutment plate 11 to abut against the inner wall of the abutment groove, completing the position locking of the box body 1 and the mounting cover 2.

[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the protective component includes a closing groove provided on one side of the outer wall of the connecting seat 5, the inner side of the closing groove is connected to the inner side of the operating groove, the inner side of the closing groove is slidably connected to a closing cover 15, a synchronization groove 16 is provided on one side of the inner wall of the closing groove, one end of the closing cover 15 is installed with a synchronization block slidably connected to the synchronization groove 16, a dragging groove 17 is provided on one side of the closing cover 15, one end of the closing cover 15 is embedded with a magnetic block, one end of the inner wall of the closing groove is embedded with an iron block 18 corresponding to the magnetic block, and the magnetic block is adsorbed on the iron block 18. Furthermore, after the locking is completed, the dragging groove 17 on the closing cover 15 can be buckled, and the synchronization block and the synchronization groove 16 can be slid toward the inside of the closing groove to seal the pull ring 14 inside the operating groove, so that the magnetic block and the iron block 18 are adsorbed and positioned with each other to prevent the person from accidentally touching the pull ring 14 after the assembly is completed, causing the connection to become loose.

[0027] In this embodiment, if Figure 1 、 Figure 2 and Figure 3When the locking nut 15 is unlocked, the locking nut 15 is unlocked, and the locking nut 15 is unlocked, so that the locking nut 15 can be unlocked.

[0028] The implementation principle of a warp let-off gearbox for a textile machinery in the embodiment of the present application is as follows: the box body 1 and the mounting cover 2 are overlapped, and the connecting seat 5 is overlapped on the rubber pad 20, so that a part of the docking block 6 enters the inner side of the docking groove, and the overlapping plate 4 continues to squeeze to make the rubber pad 20 retract, and the docking block 6 gradually moves down and abuts against the inclined surface on the bonding plate 8, forcing the bonding plate 8 to drive the limiting block 9 to slide inside the limiting groove, while squeezing the first spring 10 and stretching the second spring 19. As the docking block 6 continues to descend, it contacts the abutting plate 11 and forces the rotating rod to rotate, and the torsion spring 12 retracts until the abutting groove is close to the rotating groove, and the abutting plate 11 is popped out to the inner side of the abutting groove by the torsion spring 12, and then no longer squeezes the overlapping plate 4, so that the rubber pad 20 rebounds a short distance, and the docking block 6 also moves a short distance, so that one end of the abutting plate 11 can abut against the inner wall of the abutting groove, completing the position locking of the box body 1 and the mounting cover 2. After the locking is completed, the drag groove 17 on the closing cover 15 can be buckled, and the synchronous block and the synchronous groove 16 can slide toward the inside of the closing groove to seal the pull ring 14 inside the operating groove, so that the magnetic block and the iron block 18 are adsorbed and positioned with each other to prevent the personnel from accidentally touching the pull ring 14 after the assembly is completed, causing the connection to become loose. When the lock of the box body 1 and the installation cover 2 is unlocked to inspect the drive motor 3, the buckle and pull groove can be buckled to reopen the closing cover 15, and then the pull ring 14 is pinched to drive the movable rod 13 to slide inside the movable groove, and the bonding plate 8 is driven to move synchronously, and the first spring 10 is squeezed again and the second spring 19 is stretched, so that the abutment plate 11 moves horizontally away from the inside of the abutment groove. At this time, the docking block 6 is no longer abutted, and the rubber pad 20 is completely rebounded. At the same time, the docking block 6 will move a distance inside the docking groove as the rubber pad 20 bounces up. At this time, loosening the pull ring 14 will not change the position of the docking block 6.

[0029] The control method of the present invention is to control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. Moreover, the present invention is used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
