[0017] The baffle 1 is a circular plate structure, and the connecting shaft 6 at both ends of the baffle 1 is used to connect with the rack to support the cloth roller rack. The adjusting shaft 10 is rotationally connected with the second circular tube 3, and only the circumferential rotation is connected, and the axial displacement cannot occur. When the adjusting shaft 10 is rotated, the first circular tube 2 can be pulled to be in butt joint with the second circular tube 3 due to the threaded connection between the adjusting shaft 10 and the first circular tube 2. At this time, the arc-shaped protrusions 5 on the first circular tube 2 and the second circular tube 3 are in butt joint, and the protrusions 5 on the connecting tube 4 are located on the inner side. At this time, the length of the entire cloth roller rack is in the shorter gear. The radius of the protrusions 5 on the connecting tube 4 and the protrusions 5 on the first circular tube 2 and the second circular tube 3 is consistent, and the central angle is less than or equal to 180°. In this embodiment, the central angle of the protrusions 5 is 180°, and the protrusions 5 are semicircular ring structures on the outer surfaces of the connecting tube 4, the first circular tube 2 and the second circular tube 3. In the state of the shorter gear of the cloth roller rack, the first circular tube 2 and the second circular tube 3 are in butt joint, that is, the protrusions 5 on the first circular tube 2 and the protrusions 5 on the second circular tube 3 are in butt joint and are directed to the outer side of the baffle 1 in the radial direction, and at this time, the protrusions 5 on the connecting tube 4 are directed to the inner side of the baffle 1 in the radial direction, so the protrusions 5 on the connecting tube 4 do not interfere with the protrusions 5 on the first circular tube 2 and the second circular tube 3. Since the inner recess is arranged in the protrusions 5 at the butt joint of the first circular tube 2 and the second circular tube 3, the connecting tube 4 is sleeved on the outside of the first circular tube 2 and the second circular tube 3 and is located in the inner recess, so it does not affect the butt joint of the protrusions 5 on the first circular tube 2 and the second circular tube 3, and the flatness after the butt joint of the protrusions 5 can be maintained. When the length of the telescopic roller needs to be adjusted to make the length of the cloth roller rack be in the longer gear, the first circular tube 2 and the second circular tube 3 can be spaced apart by rotating the adjusting shaft 10. When the spacing is greater than the axial length of the protrusions 5 on the connecting tube 4, the connecting tube 4 can be rotated to make the protrusions 5 on the connecting tube 4 butt joint with the protrusions 5 on the first circular tube 2 and the second circular tube 3. Then the adjusting shaft 10 is reversely rotated to make the first circular tube 2 and the second circular tube 3 close to each other to clamp the protrusions 5 on the connecting tube 4 in the middle. At this time, the length of the telescopic roller is increased, and the cloth roller rack is in the longer gear.

[0018] The cloth roller rack in the above form can realize the adjustment of two gears with different lengths to improve the use range of the cloth roller rack.

[0019] Four telescopic rollers are arranged between the baffles 1 in this embodiment, and a gap is formed between the four telescopic rollers. Of course, the number of telescopic rollers can be six or eight in other embodiments.

[0020] There is a gap between the four telescopic rollers, and the cloth manufactured by the water jet loom has moisture. Therefore, a hollow structure is formed in the inside after being wound on the cloth roller rack to facilitate the evaporation of moisture.

[0021] The end of the protruding part 5 on the first circular tube 2 is provided with a positioning protrusion 12, the end of the protruding part 5 on the second circular tube 3 is provided with a positioning groove 11, the positioning protrusion 12 is connected with the positioning groove 11, the end of the protruding part 5 on the connecting tube 4 is provided with a positioning groove 11, the end of the protruding part 5 on the connecting tube 4 is provided with a positioning protrusion 12, when the protruding part 5 on the connecting tube 4 is connected with the protruding part 5 on the first circular tube 2 and the protruding part 5 on the second circular tube 3, the positioning protrusion 12 on the protruding part 5 on the first circular tube 2 is connected with the positioning groove 11 on the protruding part 5 on the connecting tube 4, and the positioning protrusion 12 on the protruding part 5 on the connecting tube 4 is connected with the positioning groove 11 on the protruding part 5 on the second circular tube 3.

[0022] In order to stabilize the state of the cloth roller frame in the longer gear, the positioning protrusion 12 and the positioning groove 11 are arranged at the ends of the protruding part 5 on the connecting tube 4, and the positioning groove 11 and the positioning protrusion 12 are arranged at the joint of the protruding part 5 on the first circular tube 2 and the second circular tube 3, so that when the protruding part 5 on the connecting tube 4 is connected with the protruding part 5 on the first circular tube 2 and the second circular tube 3, the positioning protrusion 12 on the protruding part 5 on the first circular tube 2 is connected with the positioning groove 11 on the protruding part 5 on the connecting tube 4, and the positioning protrusion 12 on the protruding part 5 on the connecting tube 4 is connected with the positioning groove 11 on the protruding part 5 on the second circular tube 3, so that in actual work, the connecting tube 4 is limited by the positioning protrusion 12 and the positioning groove 11 between the first circular tube 2 and the second circular tube 3, and the relative circumferential displacement is not found, so that the connection between the protruding parts 5 is stable, and the surface is flat.

[0023] The driving gear 7 is arranged on the connecting shaft 6 in the center of the baffle 1 connected with the second circular tube 3, the driven gear 8 is arranged at the end of each adjusting shaft 10, and the driven gear 8 is engaged with the driving gear 7. The driving gear 7 and the connecting shaft 6 can rotate freely, that is, they are independent of each other. By rotating the driving gear 7, the driven gear 8 can be driven to rotate, so that the adjusting shaft 10 rotates, the first circular tube 2 and the second circular tube 3 are away from or close to each other, and the length adjustment of the telescopic roller can be completed. All the adjusting shafts 10 are synchronously operated, the adjusting process is simple and convenient, and the efficiency is high.

[0024] The operation watch 9 is arranged at the edge of the driving gear 7. By operating the operation watch 9, the rotation of the driving gear 7 is more convenient.
