DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1 and Figure 2 The utility model provides a double cloth guide roller for an overflow dyeing machine, comprising a guide roller frame 1, a mounting structure 2 is mounted on the guide roller frame 1 by bolts, a connecting shaft 3 is fixed in the mounting structure 2, and the connecting shaft 3 is rotatably connected to the mounting structure 2, and the connecting shaft 3 is provided with two ends respectively fixed at both ends of the guide roller 4;

[0023] The cloth is placed on the surface of the guide roller 4, and the cloth is pulled by the overflow dyeing machine, so that the cloth moves on the surface of the guide roller 4. At the same time, the guide roller 4 will rotate to keep the cloth in a normal running position, and can also be used for the cloth discharge, thus realizing a double guide effect.

[0024] See also Figure 1 , Figure 3 and Figure 4 The utility model provides a double cloth guide roller for an overflow dyeing machine. The mounting structure 2 includes a fixing seat 21, which is fixed to the surface of the guide roller frame 1 by bolts. A card slot 22 is provided inside the fixing seat 21, and a card block 23 is inserted into the card slot 22. The card block 23 is integrally formed at the bottom of the mounting cover 24. A shaft opening 25 is provided in both the fixing seat 21 and the mounting cover 24. A connecting shaft 3 is placed inside the shaft opening 25, and the connecting shaft 3 can rotate inside the shaft opening 25. A pressing structure 26 is provided on the edge of the fixing seat 21, and a positioning structure 27 is provided inside the fixing seat 21.

[0025] Place the connecting shaft 3 in the shaft opening 25 of the fixing seat 21, then align the block 23 on the installation cover 24 with the card slot 22, and then translate the installation cover 24 so that the block 23 slides into the card slot 22. At this time, the installation cover 24 will limit the connecting shaft 3 in the shaft opening 25 to achieve the installation and fixation of the connecting shaft 3. Otherwise, the connecting shaft 3 can be disassembled to achieve convenient disassembly, maintenance or installation of the connecting shaft.

[0026] The clamping structure 26 includes a fixing block 261, which is fixed to the edge of the fixing seat 21 by bolts, and a rotating column 262 in a vertical state is arranged inside the fixing block 261, and the rotating column 262 is rotatably connected to the fixing block 261, and a threaded rod 263 is integrally formed at the upper end of the rotating column 262, and the threaded rod 263 protrudes from the top of the fixing block 261, and a clamping block 264 is threadedly connected to the threaded rod 263, and a surface of the clamping block 264 adjacent to the installation cover 24 is provided with a pressing port 265, and a pressing block 266 is arranged at the edge of the installation cover 24;

[0027] When the installation cover 24 is installed on the fixing seat 21, the pressing block 266 will slide into the pressing port 265, and the surface of the installation cover 24 will fit with the surface of the pressing block 264 to limit the pressing block 264 and prevent the pressing block 264 from rotating with the threaded rod 263. Then, the rotating column 262 is rotated to rotate the threaded rod 263. Since the threaded rod 263 is threadedly connected with the pressing block 264, when the threaded rod 263 rotates, the pressing block 264 will move downward, and then the pressing block 266 is pressed downward to press the installation cover 24 against the surface of the fixing seat 21, so as to achieve stability when the installation cover 24 is installed and prevent the installation cover 24 from sliding later.

[0028] The positioning structure 27 includes a mounting groove 271, which is opened inside the fixing seat 21. Springs 272 are installed at both the front and rear ends of the mounting groove 271, and a telescopic rod 276 is arranged in the middle of the spring 272. The upper end of the spring 272 and the telescopic end of the telescopic rod 276 are fixed to the bottom end surface of the top plate 273. The telescopic rod 276 can effectively prevent the spring 272 from bending and deforming, and has the function of positioning the top plate 273. The left and right elbows at the front and rear ends of the top plate 273 are processed so that when the mounting cover 24 is translated on the surface of the fixing seat 21, the top plate 273 will be pressed down, and will not be resisted by the top plate 273. The front and rear sides of the top plate 273 are integrally formed with limiting protrusions 275 that are slidably connected in a vertical state along the inner wall of the fixing seat 21, which are used to prevent the top plate 273 from sliding out of the top surface of the fixing seat 21 too much. A positioning block 274 that is connected to the mounting cover 24 is integrally formed on the top of the top plate 273.

[0029] When the installation cover 24 translates along the surface of the fixing seat 21, the installation cover 24 will press down the top plate 273, causing the top plate 273 to slide downward along the inner wall of the fixing seat 21. At the same time, the spring 272 is compressed to generate elastic force. When the spring 272 loses its force and pushes the top plate 273, causing the positioning block 274 to slide into the interior of the installation cover 24, the installation of the installation cover 24 is completed to achieve pre-fixation, which is beneficial for docking installation.

[0030] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
