Referring to fig. 1-7, the present invention provides a technical solution: a cloth guide mechanism of a loom comprises an inverted n-shaped support frame 1, wherein a first guide roller 2, a second guide roller 3 and a third guide roller 4 are rotatably connected inside the support frame 1, two negative pressure pipes 15 are fixedly connected to the support frame 1, a connecting pipe 16 communicated with the inside of the negative pressure pipe 15 is fixedly connected to the negative pressure pipe 15, the connecting pipe 16 is communicated with external dust collection equipment, the two negative pressure pipes 15 respectively extend into the first guide roller 2 and the second guide roller 3 and are rotatably connected with the first guide roller 2 and the second guide roller 3, and an anti-deviation mechanism is arranged on the third guide roller 4;

the external dust suction device is a common component with the same function, which is well known in the art, and therefore not described in detail.

The first guide roller 2, the second guide roller 3 and the third guide roller 4 are arranged in a triangular shape, the first guide roller 2 and the third guide roller 4 are arranged horizontally, and the second guide roller 3 is positioned below the first guide roller 2 and the third guide roller 4;

by arranging the first guide roller 2, the second guide roller 3 and the third guide roller 4 in a triangular shape, when the cloth needs to be guided, one end of the cloth firstly penetrates through the upper surface of the first guide roller 2, then is contacted with the lower surface of the second guide roller 3, and then is contacted with the upper surface of the third guide roller 4, so that the cloth is limited by the first guide roller 2, the second guide roller 3 and the third guide roller 4, and is connected with external processing equipment, so that the cloth can be in a tight state under the limitation of the first guide roller 2, the second guide roller 3 and the third guide roller 4, and meanwhile, the cloth is conveyed under the pulling of the external processing equipment;

further, cleaning plates 18 are respectively arranged on the surfaces of the first guide roller 2 and the second guide roller 3, one ends of the cleaning plates 18, which are not contacted with the first guide roller 2 and the second guide roller 3, are triangular, and air inlet grooves 19 are respectively arranged on the first guide roller 2 and the second guide roller 3;

a dust suction groove 17 is formed in the negative pressure pipe 15, and the angle of the dust suction groove 17 is positioned on one side of the first guide roller 2 and the second guide roller 3, which is contacted with the cloth;

when the cloth needs to be guided, two sides of the cloth are respectively contacted with the cleaning plates 18 on the first guide roller 2 and the second guide roller 3, so that in the moving process of the cloth, dust and thread ends adhered to the cloth are cleaned by the cleaning plates 18, and at the moment, external dust collection equipment is started, so that negative pressure enters the inside of the negative pressure pipe 15 through the connecting pipe 16 and acts between the two adjacent cleaning plates 18 through the dust collection groove 17 and the air inlet groove 19, and the dust and the thread ends are introduced into the inside of the negative pressure pipe 15 by suction force generated by the negative pressure and enter external dust collection equipment through the connecting pipe 16, so that the cleaning of the cloth is finished, and meanwhile, the cleaned dust and the thread ends are collected, so that the subsequent processing effect of the cloth is ensured;

further, the deviation prevention mechanism comprises two limiting rings 5, the two limiting rings 5 are respectively connected to a third guide roller 4 in a sliding manner, a sliding groove 6 is formed in the third guide roller 4, two sliding blocks 7 are respectively connected to the inner portion of the sliding groove 6 in a sliding manner, the two sliding blocks 7 are respectively fixedly connected with the two limiting rings 5, a triangular clamping groove 20 is formed in the inner wall of the sliding groove 6, and two clamping rods 13 movably clamped with the clamping groove 20 are arranged on the sliding blocks 7;

a moving groove 8 is formed in the sliding block 7, a pulling block 9 is connected to the inside of the moving groove 8 in a sliding mode, a moving block 10 is arranged inside the sliding block 7, the pulling block 9 is fixedly connected with the moving block 10, a return spring 14 is fixedly connected to the inside of the sliding block 7, and one end, close to the moving block 10, of the return spring 14 is fixedly connected with the moving block 10;

a V-shaped limiting groove 11 is formed in the moving block 10, two groove bodies of the limiting groove 11 are respectively connected with limiting shafts 12 in a sliding mode, and two clamping rods 13 are respectively fixedly connected to the two limiting shafts 12;

when the cloth is faced with different widths, the pulling block 9 is pulled, the pulling block 9 is stressed to drive the moving block 10 to slide upwards, the sliding of the moving block 10 enables the limiting shaft 12 to slide downwards in the limiting groove 11, so that the clamping rod 13 is limited by the limiting shaft 12 to be separated from the inside of the clamping groove 20 along with the reduction of the angle of the limiting groove 11, the limiting rings 5 can be easily moved at the moment, the distance between the two limiting rings 5 is changed, the limiting rings 5 can limit the cloth with different widths, the cloth is prevented from being shifted in the conveying process, and the subsequent processing effect on the cloth is ensured;

when the limiting ring 5 is adjusted to a specified position, no force is exerted on the pulling block 9, so that under the action of the return spring 14, the moving block 10 is reset, the clamping rod 13 is clamped into the clamping groove 20 again, and the limiting ring 5 is fixed;

through the return spring 14, under the elastic performance that the return spring 14 itself possesses, make the movable block 10 and draw the piece 9 under the influence that does not receive external force, be difficult for producing the removal of free and convenient, consequently ensure the joint effect of kelly 13 and draw-in groove 20, and then ensure the fixed effect to spacing ring 5.

The working principle is as follows: when facing the cloth of different width, pulling block 9 atress drives movable block 10 and upwards slides, the slip of movable block 10 makes spacing axle 12 slide downwards in the inside of spacing groove 11 this moment, consequently along with diminishing of spacing groove 11 angle, kelly 13 breaks away from the inside of draw-in groove 20 by the restriction of spacing axle 12, can easily move spacing ring 5 this moment, consequently, change the interval between two spacing rings 5, when spacing ring 5 adjusts to appointed position, do not exerting oneself pulling block 9, consequently, under reset spring 14's effect, movable block 10 resets, and then make kelly 13 block into the inside of draw-in groove 20 again, consequently, accomplish the fixed to spacing ring 5.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
