Description

Technical Field

[0001] The utility model relates to the technical field of water jet looms, in particular to a guiding mechanism of an ultra-wide water jet loom. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed.

[0003] In the patent "A guiding mechanism for an ultra-wide water jet loom" with publication number "CN211947414U", the scheme is to set guiding rings on both sides of the cloth to prevent the cloth from shifting when winding. The guiding rings can adjust the spacing between the guiding rings according to the width of the cloth, and then fix the clamping plate to the rotating sleeve by bolts. However, this technical solution still has shortcomings:

[0004] When the cloth is conveyed through the water jet loom, in order to ensure the subsequent convenient transportation and use of the cloth, the winding position of the cloth on the conveying roller will be centered, that is, the cloth needs to be consistent with the middle position on the conveying roller during transportation. However, when adjusting the position of the guide ring, this technical solution cannot ensure that the two guide rings approach or move away from each other synchronously. The staff is required to measure their positions to ensure that the cloth is conveyed in the center position on the conveying roller after guidance. The operation is not convenient enough.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 A guiding mechanism of an ultra-wide width water jet loom comprises a machine body 1 for preparing an ultra-wide width cloth 3. Two opposite inner walls of the machine body 1 are respectively provided with two through grooves 2, and the ultra-wide width cloth 3 is arranged in the two through grooves 2. Guide rollers 5 are installed on the side walls of two mounting plates 4 away from the through grooves 2, and the lower side wall of the ultra-wide width cloth 3 is in contact with the upper surface of the guide roller 5.

[0023] The guiding mechanism includes two mounting plates 4, which are fixedly connected to the side walls of the machine body 1 close to one of the through grooves 2. The side walls of the two mounting plates 4 close to each other are rotatably connected to the first roller 7 through the first rod 6. A plurality of fixing rods 8 are fixedly connected above the side walls of the two mounting plates 4 close to each other. The side walls of the plurality of fixing rods 8 are slidably connected to two guiding plates 9. A bidirectional lead screw 10 is rotatably connected between the lower side walls of the two mounting plates 4. The side walls of the bidirectional lead screw 10 are respectively threadedly connected to the side walls of the two guide plates 9.

[0024] Furthermore, when the bidirectional screw 10 rotates clockwise or counterclockwise, the two guide plates 9 can synchronously approach or move away from each other, which can ensure that the two guide plates 9 are symmetrical along the center of the extra-wide cloth 3, that is, it ensures that the position of the extra-wide cloth 3 on the conveying roller is centered after conveying, which is convenient for subsequent convenient conveying and use, and avoids the problem in the prior art that the two guide rings cannot be guaranteed to approach or move away synchronously, and the staff needs to measure their positions, so that the cloth can be wound up in the center position on the conveying roller after being guided, which is not convenient enough.

[0025] One end of the bidirectional lead screw 10 passes through the side wall of one of the mounting plates 4 and is fixedly connected to a hand wheel 11 . A thread is formed on the side wall of the bidirectional lead screw 10 close to the hand wheel 11 , and a nut 12 is connected to the thread.

[0026] Furthermore, after the positions of the two guide plates 9 are adjusted, the nut 12 is rotated so that the side wall of the nut 12 fits tightly with the side wall of the mounting plate 4, thereby fixing the rotation position of the bidirectional screw 10, thereby ensuring the stable position of the two guide plates 9.

[0027] The side walls of the two mounting plates 4 that are close to each other are rotatably connected to the second roller 14 through the second rod 13. The second roller 14 is located directly above the first roller 7. The side walls of the extra-wide cloth 3 are respectively in contact with the surfaces of the first roller 7 and the second roller 14. The first roller 7 and the second roller 14 are both arranged through the two guide plates 9.

[0028] A motor 15 is fixedly connected to the side wall of one of the mounting plates 4 through a bracket, a movable end of the motor 15 is fixedly connected to one end of the first rod 6, a first gear 16 is fixedly connected to the side wall of the first rod 6, and a second gear 17 meshing with the first gear 16 is fixedly connected to the side wall of the second rod 13.

[0029] Furthermore, when the first roller 7 and the second roller 14 rotate to convey the extra-wide cloth 3 , not only can the extra-wide cloth 3 be leveled, but also excess water on the extra-wide cloth 3 can be squeezed out.

[0030] When the extra-wide cloth 3 is formed and transported out in the machine body 1, the extra-wide cloth 3 passes between the first roller 7 and the second roller 14, and then is transported out through the guide roller 5;

[0031] When the extra-wide cloth 3 is initially passed through, in order to ensure the normal passing of the extra-wide cloth 3, the two guide plates 9 are away from the extra-wide cloth 3, and then the hand wheel 11 is rotated clockwise to make the bidirectional screw 10 rotate clockwise, so that the two guide plates 9 can be synchronously close to each other to guide and convey the extra-wide cloth 3, and at this time, it can be ensured that the two guide plates 9 are symmetrical along the center of the extra-wide cloth 3, that is, it is ensured that the position of the extra-wide cloth 3 on the conveying roller after conveying is centered, which is convenient for subsequent convenient conveying and use;

[0032] After the positions of the two guide plates 9 are adjusted, the nut 12 is rotated so that the side wall of the nut 12 is closely fitted with the side wall of the mounting plate 4, thereby fixing the rotation position of the bidirectional lead screw 10, thereby ensuring the stability of the positions of the two guide plates 9;

[0033] When the extra-wide cloth 3 is conveyed, the driving motor 15 rotates clockwise, and under the action of the first gear 16 and the second gear 17, the first roller 7 rotates clockwise and the second roller 14 rotates counterclockwise, so that the extra-wide cloth 3 can be conveyed normally, and in the conveying process, not only the extra-wide cloth 3 can be leveled, but also the excess water on the extra-wide cloth 3 can be squeezed out.

[0034] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
