Referring to FIG. 4, in the replacement type folding roller device of the preferred embodiment of the present invention, the kneading roller 4a serving as the rolling operation is subjected to the rolling operation, so that the kneading roller 4a When the damage needs to be replaced, the two positioning components 13 disposed on the frame wall 1 may be removed, and the two exchange seats 2 may be manually rotated at a positioning angle or driven by the power transmission member 20. The exchange base 2 is rotated at a positioning angle. In the present embodiment S, the rotation angle is 180, so that the two extended replacement seats 23 and their kneading rollers 4a, 4b are exchanged positions. Thus, the kneading roller 4b can continue to be pressed with the lower roller of the multi-axis mechanical device in 200924962, and the damaged kneading roller 4a can be replaced subsequently without affecting the operation of the original production line. Referring to FIG. 5, when the crushing roller 4a is replaced by the subsequent replacement, the positioning member 25 on the two replacement seats 23 of the fixed folding roller 4a is removed, so that the two replacement seats are replaced. 23% can be separated from the exchange base 2' and a mobile device 5 such as a car is pushed to the side close to the one of the rack walls 1. Referring to FIG. 6, the damaged twisting roller 4a and its replacement seat 23 are directly moved by the suspension device or the manual force, and the two replacement seats 23 of the damaged twisting roller 4a are respectively placed in the axial direction. The sliding seat 34 of the mobile component 3 and the platform of the mobile device 5 are mounted. Please refer to FIG. 7 'moving axially on the shaft 31 by the sliding seat 34' or externally power or manpower to rotate the transmission member 33, so that the sliding seat 34 can move axially in the shaft 31. The sliding seat 34 is further driven to axially move the kneading roller 4a, and the mobile device 5 is fixed, and the kneading roller 4a is moved on the platform of the mobile device 5 until the sliding seat 34 moves to the axis. On the other side of the rod 31, a thrust is applied to the kneading roller 4a so that the replacement seat 23 placed in the sink can be moved to the platform of the mobile device 5 to complete the removal of the registration light wheel 4a. . When the repairing or preparing twisting roller 4 needs to be reinstalled in the two exchange seats 2, the winding roller 4 and the two-terminal replacement seat 23 are first disposed in the manner of reverse operation according to the above steps. On the platform of the mobile device 5, the brigade has a replacement seat 23 disposed on the sliding seat 34, and the shaft 31 is rotated by 200924962, so that the sliding seat 34 drives the kneading roller 4 to move axially, and The two replacement seats 23 are respectively moved to the two exchange seats 2, and the two replacement seats 23 are fixed to the exchange seat 2 to fix the preliminary coupling roller 4. Therefore, when the user wants to replace the preparatory twisting roller 4 in use again, the replacement can be completed only by rotating the parent to replace the folding light wheel 4a, 4b. As described above, compared with the conventional twisting roller device, the kneading roller must be removed from the vertical direction, which is limited by the space of the factory, inconvenient to use, etc., and the present invention rotates and exchanges the kneading roller by the exchange seat 2. 4a, 4b, the folding rollers 4a, 4b are replaced by each other, and the replacement of the two coupling rollers 4a, 4b does not affect the operation of the production line. And the sliding seat 34 is used to axially move the shaft 31, so that the sliding seat 34 drives the jj to move the folding roller 4a to the platform of the mobile device 5; and the sliding seat 34 is used in the opposite step manner. A new combination of the parent wheel 4 is combined with the exchange seat 2 for the next replacement, which can save the time and labor required for replacing the composite wheel 4, and improves the convenience of the replacement of the light wheel. . While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims. 1-11-200924962 [Schematic description of the drawings] Fig. 1 is a perspective view of a replacement folding roller device according to a preferred embodiment of the present invention.
