[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] See also Figure 1-Figure 5As shown, the purpose of this embodiment is to provide an improved structure of a cloth guide roller, including a mounting frame 1, an inner wall of the mounting frame 1 is provided with a sliding cavity 11, and a second rotating shaft 14 is slidably connected inside the sliding cavity 11, and the outer periphery of the second rotating shaft 14 is rotatably connected to the cloth guide roller body 2, and the outer peripheries of both ends of the second rotating shaft 14 are fixedly connected to the limit plate 3, and the bottom of the limit plate 3 is provided with an adjustment component for adjusting the tension, the top of the mounting frame 1 is fixedly connected to two fixed blocks 7, and the side wall of the fixed block 7 is provided with a cleaning component for cleaning chemical fiber fabrics, and the cleaning component includes two mounting blocks 9, the bottom of the mounting block 9 is installed on the top of the fixed block 7, and the interior of the fixed block 7 is provided with a The disassembly and assembly components of the fixed mounting block 9 are provided with symmetrical grooves 4 on the side walls of the fixed block 7 and the mounting block 9. The two grooves 4 on the same side of the fixed block 7 and the mounting block 9 form a rotating hole, and the dust-sticking roller 8 is rotatably installed in the rotating hole. A lifting groove 13 is provided in the fixed block 7. A slide groove communicating with the lifting groove 13 is provided through the side wall of the fixed block 7. The interior of the lifting groove 13 is slidably connected to a moving block 15. The side wall of the moving block 15 is fixedly connected to a rotating shaft 12. The outer periphery of the rotating shaft 12 is rotatably connected to a guide roller 10. The bottom of the moving block 15 is fixedly connected to a spring 16, and the other end of the spring 16 is fixedly connected to the bottom of the lifting groove 13;

[0027] When the chemical fiber fabric passes between the sticky roller 8 and the guide roller 10, it will drive the sticky roller 8 to rotate, cleaning the dust and chemical fiber debris on the fabric. After being used for a long time, the sticky roller 8 wears and becomes smaller in diameter, causing the gap between the sticky roller 8 and the guide roller 10 to become larger, causing the spring 16 to lose its force and rebound, driving the moving block 15, the rotating shaft 12 and the guide roller 10 to move upward, so that the surface of the fabric is always in close contact with the sticky roller 8.

[0028] The adjustment assembly includes a bidirectional screw rod 25, which is rotatably mounted between the two side walls of the mounting frame 1, and a motor 5 is fixedly mounted on the outer side of one side wall of the mounting frame 1. The output shaft of the motor 5 passes through the housing of the mounting frame 1 and is fixedly connected to one end of the bidirectional screw rod 25. Two bilaterally symmetrical screw nuts 26 are threadedly mounted on the bidirectional screw rod 25. The top of the screw nut 26 is hinged to a connecting plate 21, and the other end of the connecting plate 21 is hinged to the bottom of the limit plate 3.

[0029] The bidirectional screw rod 25 is provided with two sections of threads in opposite directions, and the rotation direction of the two sections of threads is symmetrically arranged with the midpoint of the bidirectional screw rod 25 as the center. The screw nut 26 is symmetrically arranged with the midpoint of the bidirectional screw rod 25 as the center. By starting the motor 5, the bidirectional screw rod 25 can be rotated, so that the two screw nuts 26 move closer or farther away. At the same time, the two connecting plates 21 rotate to drive the limit plate 3, the second rotating shaft 14 and the guide roller body 2 to move upward or downward, thereby adjusting the tension of the chemical fiber fabric during transportation.

[0030] The disassembly assembly includes at least a connecting block 18, the top of the connecting block 18 is fixedly connected to the bottom of the mounting block 9, a special-shaped groove 19 is provided inside the fixing block 7, the connecting block 18 is slidably installed inside the special-shaped groove 19, and the disassembly assembly also includes a special-shaped groove 19, a fixing rod 24 is fixedly connected to the inside of the special-shaped groove 19, a slider 23 is slidably connected to the outer periphery of the fixing rod 24, a spring 22 is fixedly connected to one side of the slider 23, and the other end of the spring 22 is fixedly connected to the inside of the special-shaped groove 19, as shown in FIG. Figure 5 As shown, the other side of the slider 23 is fixedly connected to the control block 17, and the top of the slider 23 is fixedly connected to the protrusion 20. The shape of the protrusion 20 is L-shaped. The side wall of the connecting block 18 is penetrated by a card slot 6. When the mounting block 9 is installed on the fixed block 7, the outer periphery of the protrusion 20 is slidably inserted into the inner part of the card slot 6.

[0031] Press the two control blocks 17 at the same time. The control block 17 passes through the fixed block 7 and is connected to the slider 23. Pushing the control block 17 drives the slider 23 and the protrusion 20 to slide, so that the spring 22 is compressed. When the protrusion 20 slides out of the slot 6, the fixation of the mounting block 9 can be released. Then the connecting block 18 is slid out of the special-shaped groove 19, and the dust-sticking roller 8 can be replaced to prevent it from being used for too long and the efficiency of cleaning dust and chemical fiber debris is reduced.

[0032] When the utility model is used, the chemical fiber fabric passes between the sticky roller 8 and the guide roller 10 and passes above the guide roller body 2. The fabric during transportation drives the sticky roller 8 to rotate, and the dust and chemical fiber debris on the fabric are cleaned. After being used for a long time, the sticky roller 8 is worn and its diameter becomes smaller, resulting in a larger gap between the sticky roller 8 and the guide roller 10, causing the spring 16 to lose its strength and rebound, driving the moving block 15, the rotating shaft 12 and the guide roller 10 to move upward, so that the surface of the fabric is always in close contact with the sticky roller 8; when it is necessary to adjust the tension of the fabric during transportation, the bidirectional screw rod 25 can be rotated by starting the motor 5. The two screw nuts 26 move closer or farther away from each other, and at the same time, the two connecting plates 21 rotate to drive the limit plate 3, the second rotating shaft 14 and the cloth guide roller body 2 to move upward or downward, so as to adjust the tension during transportation by changing their positions; when it is necessary to replace the dust-sticking roller 8, the two control blocks 17 are pressed at the same time to drive the slider 23 and the protrusion 20 to slide, so that the second spring 22 is compressed. When the protrusion 20 slides out of the slot 6, the fixation of the mounting block 9 can be released, and then the connecting block 18 can be slid out of the special-shaped slot 19, and the dust-sticking roller 8 can be replaced to prevent it from being used for too long and the efficiency of cleaning dust and chemical fiber debris is reduced.
