Description

Technical Field

[0001] The utility model relates to the technical field of drawing-in devices, in particular to an automatic drawing-in device for a water jet loom. Background Art

[0002] Drawing in the warp yarns is the process of threading the warp yarns through the heald eyelets and steel teeth in a specific order. The operator first threads hundreds of sized, equal-length warp yarns through the healds one by one. Then, using a handheld steel knife, they pass through hundreds of narrow slits in the steel, threading the hundreds of yarns through the slits one by one. The distance between the heald holes varies between different brands and specifications of textile machines. Existing automatic heald drawing-in machines are only compatible with one model of machine and cannot flexibly adjust the spacing of the heald holes, resulting in poor applicability. Therefore, we have developed an automatic heald drawing-in machine to address this problem.

[0003] In order to solve the above technical problems, the Chinese patent with announcement number CN216074206U in the prior art discloses an automatic heald drawing machine, including two fixed plates, wherein the number of the fixed plates is symmetrical, and a support plate is centrally arranged between the two fixed plates, and a plurality of heald through-holes are provided on the support plate. The two fixed plates are slidably connected to the same sliding plate on opposite sides, and a plurality of sliding blocks are evenly slidably sleeved on the outer side of the sliding plate. The sliding block is fixedly connected to a connecting rod on the side facing the support plate, and a semicircular ring is fixedly connected to the end of the connecting rod.

[0004] Although the above-mentioned existing technical solution can perform automatic threading operation, improve work efficiency, and expand the scope of application of the device, after adjusting the spacing, the push rod motor is started to drive the semicircular ring forward, so as to achieve the purpose of passing the heald through the heald perforation. However, when adjusting, the screw rod is used to cooperate with the threaded block and the rotating rod to pull each group of sliding blocks backward, but the force is applied longitudinally. Although the rotating rod can be deflected, when the rotating rod pulls the sliding block, the inner wall of the sliding block away from the rotating rod side can easily collide with the outer wall of the sliding plate and become stuck, making it difficult to flexibly adjust into place, thereby affecting the adjustment effect and the practicality of the device.

An adjusting hook pulling mechanism is installed on the movable component, and a hook 19 is installed on the adjusting hook pulling mechanism. The adjusting hook pulling mechanism includes a spring-pressing component, two groups of first rubber pads 4 and a torsion component. The spring-pressing component is used to lock the position of the hook 19 after it is placed, and the torsion component is used to unlock the lock on the position of the hook 19. When in use, the device can lock the position of the hook 19 after it is placed by the spring-pressing component, and unlock the lock on the position of the hook 19 by the torsion component. The structure is simple and the operation is convenient. The adjustment and locking can be completed by pressing and twisting. The adjustment is convenient and quick, and there will be no jamming causing adjustment difficulties, which further improves the practicality of the device.

[0024] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the spring-pressing assembly includes multiple groups of positioning seats 16 installed on the movable assembly, and a connecting seat 17 is overlapped on one side of the positioning seat 16. Two groups of first rubber pads 4 are respectively installed on the opposite surfaces of the positioning seat 16 and the connecting seat 17. The interiors of the two groups of first rubber pads 4 are provided with docking holes. First, after determining the position of the hook 19, the connecting seat 17 is pushed toward the positioning seat 16, so that the card block 5 is pushed into the docking hole and enters the inner side of the card slot.

[0025] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, a card block 5 is installed at the docking hole on one side of the lap seat 17, and a plurality of card slots are arranged on the top of the positioning seat 16. The card block 5 is slidably connected to the card slot, and a locking slot is provided on one side of the card slot inside the positioning seat 16. The lap seat 17 is rotatably connected to a rotating rod 6 extending to the inner side of the plurality of locking slots. The outer wall of the rotating rod 6 is located on the inner side of each group of locking slots and is sleeved with a spring block 7. Then, the lap seat 17 continues to be squeezed. As the two groups of first rubber pads 4 retract, the card block 5 enters the inner side of the locking slot and contacts the spring block 7. The first slopes 10 on the two squeeze each other, forcing the spring block 7 to rotate around the rotating rod 6, and the connecting spring 9 is stretched accordingly.

[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, a connecting groove is provided on one side of the elastic block 7, a fixing plate 8 is installed on one side of the inner wall of the locking groove, a connecting spring 9 is installed between the inner wall of the connecting groove and the fixing plate 8, and the fitting surfaces of the clamping block 5 and the elastic block 7 are provided with a first slope 10 that fits each other, and a retraction groove is provided inside the elastic block 7 at its first slope 10, and an abutment rod is rotatably connected to the inside of the retraction groove, and an abutment plate 11 is sleeved on the outside of the abutment rod, and a reset torsion spring 12 is installed between the abutment rod and the inner wall of the retraction groove, and an abutment groove is provided inside the clamping block 5 at its first slope 10, and one side of the abutment plate 11 is provided with a first slope 10 that fits the first slope 10. 0 corresponds to the second slope 13 that fits in place. Further, after the card block 5 contacts the abutment plate 11, the first slope 10 and the second slope 13 fit and squeeze each other, forcing the abutment rod to drive the reset torsion spring 12 to retract, allowing the abutment plate 11 to completely retract to the inside of the retraction groove. Until the abutment groove is close to the retraction groove, the abutment plate 11 is ejected to the inside of the abutment groove by the reset torsion spring 12. At this time, the lap seat 17 is released, and the first rubber pad 4 rebounds and drives the card block 5 to move back the abutment plate 11 and fix it tightly against the inner wall of the abutment groove, completing the locking of the hook 19 position so that the staff can lock the hook 19 to a suitable spacing position.

[0027] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the torsion assembly includes a limit groove opened inside the positioning seat 16 and located on one side of the inner wall of the locking groove. The end of the spring block 7 away from the first slope 10 is equipped with a limit plate 14 slidably connected to the limit groove, and the end of the rotating rod 6 extending to the outside of the positioning seat 16 is equipped with a first knob 15. Furthermore, when it is necessary to adjust the spacing of the hook 19 again, twisting the first knob 15 can drive the rotating rod 6 to rotate accordingly, actively driving the spring block 7 to rotate, and the abutment plate 11 is dragged away from the inner wall of the abutment groove. At this time, the first rubber pad 4 is completely reset and rebounded, and the block 5 continues to move. After the abutment groove and the retraction groove are misaligned, the abutment plate 11 will no longer be stuck in the inner side of the abutment groove. At this time, the hook 19 can be removed and adjusted to the appropriate position and then locked.

[0028] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the movable component includes a movable groove opened on the top of the support plate 3, and a threaded rod 20 is rotatably connected to the inside of the movable groove. One end of the positioning seat 16 is slidably connected to the movable groove, and one end of the positioning seat 16 is threadedly connected to the threaded rod 20. One end of the outer wall of the support plate 3 is installed with a motor 21, and the driving end of the motor 21 extends to the inside of the movable groove and is fixedly connected to one end of the threaded rod 20. Furthermore, the cylinder 18 is started to drive the hook 19 on the support plate 3 to pass through the brown silk eye close to the warp yarn, and then the motor 21 is started to drive the threaded rod 20 to rotate inside the movable groove, driving the hook 19 on the positioning seat 16 to move horizontally to the rear of the warp yarn, and then the cylinder 18 is started to allow the warp yarn hooked by the hook 19 to pass through the brown silk eye, and then the cylinder 18 is started again to drive the hook 19 away from the warp yarn, and at the same time, the motor 21 is started to cooperate with the threaded rod 20 to drive the hook 19 to complete the reset of the horizontal position, waiting for the next round of brown threading operation.

[0029] The implementation principle of the automatic threading device of a water jet loom in the embodiment of the present application is as follows: after determining the position of the hook 19, the lap seat 17 is pushed toward the positioning seat 16, and the clamping block 5 is pushed into the docking hole and enters the inner side of the clamping groove, and the lap seat 17 is continuously squeezed. As the two sets of first rubber pads 4 retract, the clamping block 5 enters the inner side of the locking groove and contacts the spring block 7. The first slopes 10 on the two squeeze each other, forcing the spring block 7 to rotate around the rotating rod 6, and the connecting spring 9 is stretched accordingly. After the block 5 contacts the abutment plate 11, the first slope 10 and the second slope 13 fit and squeeze each other, forcing the abutment rod to drive the reset torsion spring 12 to retract, allowing the abutment plate 11 to completely retract to the inside of the retraction groove. Until the abutment groove is close to the retraction groove, the abutment plate 11 is ejected to the inside of the abutment groove by the reset torsion spring 12. At this time, the lap seat 17 is released, and the first rubber pad 4 rebounds and drives the block 5 to move back the abutment plate 11 and fix it tightly against the inner wall of the abutment groove, completing the locking of the hook 19 position for work. At the same time, the motor 21 is started to cooperate with the threaded rod 20 to drive the hook 19 to complete the reset of the horizontal position, and wait for the next round of threading operation.
