[0013] To further illustrate the technical means and effects taken by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0014] Example 1:

[0015] As Figures 1-4 shown, the utility model discloses a kind of weft yarn feeders of water-jet loom, including base 1 and stand 2, installation horizontal plate 3 is set on the upper end of stand 2, one through hole 11 is set on installation horizontal plate 3, tray 4 is rotationally set on the installation horizontal plate 3 of the upper end of through hole 11, the center of tray 4 is provided with through hole 11, the through hole 11 on installation horizontal plate 3 corresponds with the through hole 11 on tray 4;Shaft sleeve 5 is set on the installation horizontal plate 3 of the lower end of through hole 11, the inner hole of shaft sleeve 5 corresponds with through hole 11, gear sleeve 6 is rotationally set on the lower end of shaft sleeve 5, the inner wall of gear sleeve 6 is provided with screw thread, limiting post 9 is set in the inside of shaft sleeve 5, the lower end of limiting post 9 is provided with screw thread, the screw thread of limiting post 9 is connected with the screw thread of the inner wall of gear sleeve 6, motor 7 is set on the installation horizontal plate 3 of the side of shaft sleeve 5, the output end of motor 7 is provided with driving gear 8, the driving gear 8 is engaged between gear sleeve 6, limiting mechanism is set in the inside of shaft sleeve 5 or through hole 11, for limiting limiting post 9 rotation.

[0016] The base 1 is fixed to the ground, the column 2 is arranged on the base 1, the mounting plate 3 is arranged at a suitable height position of the column 2, the height position of the mounting plate 3 determines the height of the silk cake 10, so the height of the mounting plate 3 needs to match the requirement of the water jet loom. The tray 4 is arranged on the mounting plate 3, and the tray 4 is rotatably connected with the mounting plate 3 through bearings, so the tray 4 is freely rotatable, and the silk cake 10 on the tray 4 is also freely rotatable, the weft yarn is smoothly output, and of course the weft yarn needs to be tensioned, the tensioning function is realized by the tensioning mechanism in the prior art, and the yarn rack is only described in the embodiment, so the tensioning mechanism is not described herein. Under normal circumstances, in order to place the silk cake 10 on the tray 4 stably and reliably, a limiting column 9 needs to be arranged at the center of the tray 4. A common means in the prior art is to fix the limiting column 9 at the center of the tray 4, which causes that when the silk cake 10 is assembled, the silk cake 10 needs to be lifted to above the limiting column 9, and the height of the limiting column 9 is about 20 cm, which leads to high lifting height of workers carrying the silk cake 10, high difficulty, high labor intensity and potential safety hazards. Therefore, the through hole 11 is arranged on the tray 4 and the mounting plate 3 in the embodiment, the limiting column 9 is arranged in the through hole 11, and the limiting column 9 can slide up and down in the through hole 11. The gear sleeve 6 is rotatably arranged on the shaft sleeve 5 below the through hole 11, the gear sleeve 6 is hollow, an inner thread is arranged on the inner wall of the gear sleeve 6, and the lower end of the limiting column 9 is also provided with a thread, and the two are connected in cooperation. At the same time, the limiting mechanism limits the rotation of the limiting column 9, so that the limiting column 9 can only slide up and down in the through hole 11. The motor 7 on the mounting plate 3 is engaged with the gear sleeve 6 through the driving gear 8, so that when the motor 7 drives the gear sleeve 6 to rotate through the driving gear 8, the limiting column 9 is lifted and lowered under the action of the thread, so that the upper end can be retracted to the through hole 11. When the silk cake 10 is assembled, the limiting column 9 can be retracted into the through hole 11, so that the assembly lifting height of the silk cake 10 can be reduced, and only needs to be slightly higher than the height of the tray 4. After the silk cake 10 is in place on the tray 4, the limiting column 9 is lifted by the motor 7, so that the fiber of the silk cake 10 is lifted.

[0017] This form horizontally assembles the silk cake 10, and the silk cake 10 is more stable, safe and reliable when outputting weft yarn.

[0018] The limiting mechanism comprises a limiting protrusion 13 arranged on the inner wall of the through hole 11 of the mounting plate 3 and an inner concave limiting groove 12 arranged on the side wall of the limiting column 9, the limiting groove 12 is arranged in the vertical direction, and the end of the limiting protrusion 13 extends into the limiting groove 12.

[0019] The limiting mechanism adopts the design of limiting protrusion 13 and limiting groove 12, which realizes the limitation of the rotation of limiting column 9 after cooperation, and can limit the maximum stroke of the lifting of limiting column 9. The length of limiting groove 12 can be set according to actual needs. This form is more stable for limiting column 9.

[0020] An inner recess cavity 14 is arranged on the side wall of the top end of limiting column 9, and an inductor 15 is arranged in the inner recess cavity 14. The inductor 15 is connected with a controller, and the controller is connected with motor 7.

[0021] The lifting amplitude and final positioning position of limiting column 9 controlled by motor 7 can be determined according to actual conditions. For example, a control switch is used to control the start and stop of motor 7, so as to determine the lifting process of limiting column 9. Of course, it can also be automatically controlled. In this embodiment, a controller is used to control the action of motor 7. At the same time, an inner recess cavity 14 is arranged on the top of limiting column 9, and an inductor 15 is arranged in the inner recess cavity 14. In this way, the inductor 15 does not interfere with the lifting of limiting column 9, and the lifting of limiting column 9 is stable and reliable. The inductor 15 can be an infrared inductor 15, and the inductor sensing distance is set, for example, within 5 cm. When the inductor 15 is blocked, an inductive signal is sent to the controller, and the controller judges and controls the corresponding action of motor 7.

[0022] For example, before replacing the filament cake 10, the equipment is normally running. At this time, the inductor 15 on the limiting column 9 is located at the upper end of the filament cake 10, and there is no obstruction in its sensing range, which is the natural working state. When it is necessary to replace the filament cake 10, the paper tube of the filament cake 10 is taken off from the limiting column 9. In the process, the inductor 15 is blocked, and the inductor 15 transmits a signal to the controller. The controller controls the action of motor 7, drives the gear sleeve 6 to rotate, and then lowers the limiting column 9 until the inductor 15 on the limiting column 9 senses the obstruction again. The motor 7 stops moving. At this time, it indicates that the end of the limiting column 9 is located in the through hole 11. Then the controller controls the motor 7 to move in the opposite direction, so as to promote the lifting of the limiting column 9 until the inductor 15 in front of the limiting column 9 is not blocked. At this time, the end of the limiting column 9 is just exposed above the tray 4. Then the worker lifts the replaced filament cake 10 to the tray 4 and sleeves it to the end of the limiting column 9. The inductor 15 at the end of the limiting column 9 is blocked again. At this time, the controller receives the signal, controls the rotation of the motor 7, and lifts the limiting column 9 until the inductor 15 at the end of the limiting column 9 is just exposed above the filament cake 10, that is, the inductor 15 is not blocked. This process completes the automatic lifting of the limiting column 9, and can limit the filament cake 10. At the same time, it can reduce the height of the worker carrying the filament cake 10, reduce the labor intensity, improve the replacement efficiency, and the whole running process is safe and reliable.
