On the other hand, it is not convenient to adjust the water pressure of the high-pressure water flow to improve the straight line maintenance effect when the weft is delivered. Based on this, the utility model provides a wire feed frame suitable for a water jet loom to solve the problems raised in the above background technology. Utility Model Content

When the utility model is working, through the setting of a reciprocating drive mechanism, a single motor can be used to achieve synchronous control of the weft high-pressure liquid spraying timing and the weft clamping state.

[0004] The utility model solves the technical problem by adopting the following technical scheme: a wire feed frame adapted for a water jet loom, comprising a mounting frame, on which a pressure accumulator, a wire feed pipe and a reciprocating drive mechanism are respectively mounted, the wire feed pipe is driven by the reciprocating drive mechanism and reciprocates along the pressure accumulator, the pressure accumulator is threadedly provided with a wire feed pipe, the wire feed pipe is provided with an inner valve cylinder slidably connected to the pressure accumulator, the inner valve cylinder is provided with a group of valve holes a, the wire feed pipe is provided with an outer valve cylinder slidably connected to the inner valve cylinder, a liquid distribution cavity is provided inside the outer valve cylinder, a jet hole connected to the liquid distribution cavity is fixedly provided at the front end of the outer valve cylinder, the liquid distribution cavity can be periodically connected to the valve hole a as the wire feed pipe reciprocates, a water seal seat slidably fitted with the wire feed pipe is mounted on the inner valve cylinder, a sealing ring capsule is fixedly mounted on the inner wall of the jet hole, a pressure control assembly is provided on the mounting frame, and the sealing ring capsule reciprocates to change the air pressure in the sealing ring capsule through the reciprocating movement of the pressure control assembly and the wire feed pipe.

[0006] As a preferred technical solution of the utility model, a wire feeding channel is fixedly provided inside the wire inlet pipe, the front and rear ends of the wire feeding channel are both open, and a weft wire is movably installed in the wire feeding channel.

[0010] The beneficial effects of the utility model are:

[0011] 1. When the utility model is working, through the setting of the reciprocating drive mechanism, the synchronous control of the weft high-pressure liquid spraying timing and the weft clamping state can be achieved through a single motor. Through the realization of the above-mentioned dual-state synchronous control effect, on the one hand, the weft feeding efficiency and feeding accuracy can be effectively improved, and on the other hand, the feeding mechanism can be effectively simplified, thereby reducing the production and maintenance costs of the feeding structure.

[0012] 2. The utility model sets the ratio of the width of the air inlet ring to the diameter of the valve hole b so that when the sealing ring bag loses its clamping effect on the weft, the liquid in the jet hole and the inlet pipe can be increased to the set pressure. The increase in liquid pressure can improve the weft delivery efficiency and the straight line maintenance effect when the weft is delivered. The threaded connection between the inlet pipe and the pressure accumulation tube can adjust the timing of sending the high-pressure liquid to the jet hole, and then assist in adjusting the liquid pressure of the jet liquid in the liquid distribution cavity before the sealing ring bag loses its clamping effect on the weft.

[0026] When working, the liquid inlet connector 15 is connected to the external high-pressure water pumping device;

[0027] The reciprocating drive mechanism includes a passive toothed plate 11 fixed on the inlet pipe 3, the passive toothed plate 11 is slidably connected to the mounting frame 1, a servo motor 12 is mounted on the mounting frame 1, a half-face gear 13 is fixedly mounted on the output shaft end of the servo motor 12, the half-face gear 13 is transmission-connected to the passive toothed plate 11, and a reset spring 14 connected to the mounting frame 1 is sleeved on the inlet pipe 3;

[0028] By setting the reciprocating drive mechanism, when the servo motor 12 outputs the rotation speed, the inlet pipe 3 can reciprocate within the set stroke along the axial direction of the pressure accumulator pipe 2;

[0029] The operating speed of the servo motor 12 can be controlled according to the line speed;

[0030] The internal thread of the pressure accumulator tube 2 is provided with a wire entry tube 4;

[0031] A wire feeding channel is fixedly provided inside the wire inlet pipe 4, and both front and rear ends of the wire feeding channel are open. A weft wire 22 is movably installed in the wire feeding channel.

[0032] The weft thread 22 is unwound by an unwinding device for the external weft thread 22;

[0033] An inner valve cylinder 5 is installed on the inlet pipe 4 and is in sliding communication with the pressure accumulator pipe 2. A group of valve holes a6 are opened on the inner valve cylinder 5.

[0034] An outer valve cylinder 7 slidably connected to the inner valve cylinder 5 is installed on the inlet pipe 3;

[0035] By means of the threaded connection between the inlet pipe 4 and the pressure accumulator pipe 2, the timing of sending the high-pressure liquid to the jet hole can be adjusted, and then the liquid pressure of the jet liquid in the liquid distribution cavity 8 can be assisted to be adjusted before the sealing ring capsule 10 loses the clamping effect on the weft 22;

[0036] The outer valve cylinder 7 has a liquid distribution cavity 8 formed inside, and a jet hole connected to the liquid distribution cavity 8 is fixedly formed at the front end of the outer valve cylinder 7. The liquid distribution cavity 8 can be periodically connected to the valve hole a6 as the inlet pipe 3 moves back and forth.

[0037] A water seal seat 9 is installed on the inner valve cylinder 5, which is in sliding fit with the inlet pipe 3. A sealing ring bag 10 is fixedly installed on the inner wall of the jet hole. A pressure control component is provided on the mounting frame 1. The sealing ring bag 10 changes the air pressure in the sealing ring bag 10 through the reciprocating movement of the pressure control component and the inlet pipe 4.

[0038] The pressure control component includes an intake ring 17 fixed on the mounting frame 1, a ventilation flow channel 18 opened in the inlet pipe 3 and an air pump 19 fixed on the mounting frame 1. The outlet port of the air pump 19 is fixedly connected to the intake ring 17 through a pump air pipe. A group of valve holes b20 are opened in the inlet pipe 3, and the ventilation flow channel 18 can be periodically connected to the inner cavity of the intake ring 17 through the valve holes b20.

[0039] An air pressure probe 21 is fixedly installed in the pump air pipe, and the width of the air inlet ring 17 is 8 times the diameter of the valve hole b20.

[0040] By setting the ratio of the width of the air inlet ring 17 to the diameter of the valve hole b20, when the sealing ring bag 10 loses the clamping effect on the weft 22, the liquid in the jet hole and the inlet pipe 3 can be raised to the set pressure, and the delivery efficiency of the weft 22 and the straight line maintenance effect of the weft 22 when being delivered are improved by increasing the liquid pressure;

[0042] The working principle and use process of this utility model:

[0043] When in use, the mounting frame 1 is fixed to the line-in position of the water jet loom. In the initial state, the valve hole a6 is sealed by the inner valve cylinder 5 and the outer valve cylinder 7, and the interior of the sealing ring bag 10 is sufficiently pressurized, and then the weft 22 is clamped and positioned. Before work, the liquid inlet joint 15 is connected with the external high-water pumping device, the air pump 19 continuously pumps air, and the servo motor 12 outputs the speed at a constant speed. After the servo motor 12 outputs the speed, the line-in pipe 3 is controlled to reciprocate along the axial direction of the pressure accumulator tube 2. When the line-in pipe 3 is displaced in a direction away from the pressure accumulator tube 2, When the inner valve and the outer valve cylinder 7 lose their sealing effect on the valve hole a6, the high-pressure liquid in the pressure accumulator tube 2 is ejected through the jet hole, and when the inlet pipe 3 is away from the pressure accumulator tube 2 by a specified amplitude, the sealing ring bag 10 loses its clamping effect on the weft thread 22. Under the action of the high-pressure water flow, the weft thread 22 is ejected in a high-pressure straight line under the action of the high-pressure water flow, and then the weft thread 22 is fed into the warp cloth. When the inlet pipe 3 is reset, the device returns to its initial state. With the continuous driving of the servo motor 12, the weft thread 22 is then continuously fed out at a fixed length.
