Detailed implementation manners

[0034] The technical solution of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0035] The embodiment of the present utility model specifically provides a weft insertion mechanism for an air-jet loom. Please refer to Figure 1 , which includes a support frame 1 and a dust filtering component 2.

[0036] Among them, a weft yarn bobbin 11 is installed on the support frame 1, and a yarn hole 12 is formed in the support frame 1. After the weft yarn 13 on the weft yarn bobbin 11 passes through the yarn hole 12, it is weft inserted through the jetting component 14. The jetting component 14 is fixedly arranged on the support frame 1. During implementation, the support frame 1 is fixedly installed on the air-jet loom, and then the weft yarn 13 is jet-weft inserted through the jetting component 14. The jetting component 14 is a common existing jet-weft inserting component, so it will not be elaborated here.

[0037] During implementation, the dust filtering component 2 is fixedly installed on the support frame 1, and the weft yarn 13 is subjected to dust filtering treatment through the dust filtering component 2, so as to effectively filter out broken yarns and dust chips on the surface of the weft yarn 13, improve the stability of the weft insertion operation and ensure the cleanliness of the spinning environment.

[0038] Furthermore, please refer to Figure 2 , the dust filtering component 2 includes a weft inserting tube 3, a mounting component 4 fixedly arranged outside the weft inserting tube 3, a blowing component 5 installed on the weft inserting tube 3, a filtering bin 6 fixedly connected to the bottom end of the weft inserting tube 3, a chip discharging pipe 7 with the top end connected to the filtering bin 6, and a receiving component 8 fixedly connected to the bottom end of the chip discharging pipe 7.

[0039] Specifically, the weft insertion cylinder 3 is provided with insertion holes 31 for the weft yarn 13 to pass through. The installation assembly 4 includes an installation frame 41 whose upper and lower ends are respectively fixed to the support frame 1 and the weft insertion cylinder 3, and an electrostatic eliminator 42 fixed on the installation frame 41. The electrostatic eliminator 42 is attached to the outer side of the weft insertion cylinder 3. The electrostatic eliminator 42 is a common existing electrostatic elimination component, which can eliminate static electricity on the surface of the weft yarn 13 passing through the inside of the weft insertion cylinder 3, thereby reducing the attachment of broken yarns and dust on the surface of the weft yarn 13 and improving the convenience of subsequent debris removal and filtration.

[0040] Among them, please refer to Figure 3 As shown in Figure 3 , the air blowing assembly 5 includes an annular pipe 51 fixed to the inner wall of the weft insertion cylinder 3, a flange pipe 52 integrally fixed with the annular pipe 51, and an air pump 53 whose air delivery end is fixedly connected to the flange pipe 52. The outer sides of the flange pipe 52 and the air pump 53 are both fixed to the annular pipe 51 on the weft insertion cylinder 3. The air pump 53 sends the debris removal air flow into the inside of the annular pipe 51. When the weft yarn 13 passes through the middle of the annular pipe 51, it continues to be sent downward, and the debris on its surface can be blown off by the debris removal air flow.

[0041] During implementation, to realize the blowing of the debris removal air flow, a spray pipe 54 is fixedly installed at the bottom end of the annular pipe 51, and a nozzle 55 is fixedly installed at the output end of the spray pipe 54. The output direction of the nozzle 55 points to the weft yarn 13, so that when the weft yarn 13 is fed downward, it can also be guided and blown downward by the debris removal air flow ejected from the nozzle 55, improving the convenience of weft insertion, and at the same time, the debris on the surface of the weft yarn 13 can be blown off by the debris removal air flow.

[0042] Furthermore, the filter bin 6 includes a bin body 61 integrally fixed to the bottom end of the weft insertion cylinder 3, a filter opening 62 opened at the bottom end of the bin body 61, and a debris discharge opening 63 opened on the side wall of the bin body 61. The inner wall of the filter opening 62 is in sliding contact with the weft yarn 13, so that when the weft yarn 13 is led downward, it can slide along the filter opening 62 in a fitting manner, so that the broken yarns and particulate dust on the surface of the weft yarn 13 can be intercepted by the filter opening 62, and under the blowing of the debris removal air flow, the debris is blown into the debris discharge opening 63.

[0043] Specifically, the top end of the debris discharge pipe 7 is fixedly connected to the debris discharge opening 63. The receiving assembly 8 includes a collecting cover 81 fixedly connected to the bottom end of the debris discharge pipe 7 and a receiving tray 82 arranged below the collecting cover 81 in a detachable and fixed manner. The dust and debris are sent into the collecting cover 81 through the discharge pipe 7 and received by the receiving tray 82.

[0044] Among them, please refer to Figure 4 And Figure 5, the receiving tray 82 includes a bottom plate 821, a sealing frame 822 fixedly arranged on the upper surface of the bottom plate 821, and a slot 823 opened on the sealing frame 822. The bottom end of the collection cover 81 is inserted into the slot 823, so that the peripheral edge of the bottom end of the collection cover 81 can be in close contact with the slot 823, improving the airtightness. There are aligned notches 83 on the outer sides of the collection cover 81 and the bottom plate 821. When it is necessary to remove the bottom plate 821, the bottom plate 821 can be removed from the weft yarn 13 through the notch 82.

[0045] During implementation, a magnetic ring 824 is fixedly arranged in the slot 823, and the bottom end of the collection cover 81 is magnetically connected to the magnetic ring 824. The collection cover 81 is supported by magnetic materials, enabling the bottom plate 821 to be detachably connected to the collection cover 81 through the magnetic ring 824. When it is necessary to process the collected dust and debris, the bottom plate 821 and the collection cover 81 can be quickly separated.

[0046] Among them, a filter groove 825 is opened inside the slot 823, and a filter screen 826 is fixedly arranged in the filter groove 825, so that the debris-removing air flow drives the debris to blow towards the filter groove 825, and the filter screen 826 intercepts the debris.

[0047] The control mode of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present utility model is mainly used to protect mechanical devices, so the control mode and wiring layout of the present utility model will not be explained in detail.

[0048] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
