Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, the present invention provides a technical solution: a roller replacement device, including a base plate 1, both side surfaces of the base plate 1 are fixedly connected with lap plates 31, the lap plates 31 are threadedly connected with locking bolts 32, the locking bolts 32 are threadedly connected with limiting nuts 33, a C-shaped groove is opened on the lap plate 31, and one end of the locking bolt 32 is located in the C-shaped groove.

[0030] The lap plate 31 is placed on the fixing frame through the C-shaped groove, and the locking bolt 32 is rotated on the lap plate 31 so that the locking bolt 32 is against the fixing frame to support the base plate 1. The limiting nut 33 can also be rotated and moved by the locking bolt 32 to a contact state with the lap plate 31, thereby limiting the locking bolt 32.

[0031] A pallet 2 is arranged above the base plate 1, three support rollers 3 are installed on the pallet 2, two control boxes 6 are installed on the base plate 1, a rotating shaft 5 is arranged above the base plate 1, and both ends of the rotating shaft 5 are rotatably connected to the two control boxes 6 respectively, a rotating component for driving the rotating shaft 5 to rotate and a limiting component for limiting the rotating shaft 5 are arranged on the control box 6, and a supporting component is arranged on the base plate 1.

[0032] The rotating assembly includes a crank 34, one end of the rotating shaft 5 passes through the control box 6 and is fixedly connected to the crank 34, and a handle 35 is fixedly connected to the crank 34, so that the handle 35 can drive the rotating shaft 5 to rotate through the crank 34, which is a way of providing a rotational driving force for the rotating shaft 5, and the rotating shaft 5 can also be driven to rotate by a motor.

[0033] The limiting assembly includes a first transmission gear 8 fixedly connected to the rotating shaft 5, and a transmission shaft 9 rotatably connected to the control box 6. A second transmission gear 10 is fixedly connected to the transmission shaft 9, and the second transmission gear 10 is meshed with the first transmission gear 8. A moving rod 11 is slidably connected to the control box 6, and a block 12 is fixedly connected to the bottom end of the moving rod 11, and the block 12 is adapted to the second transmission gear 10.

[0034] Since the second transmission gear 10 and the first transmission gear 8 are in a mutually meshing state, the movable rod 11 can drive the block 12 to be inserted into the second transmission gear 10 to limit the second transmission gear 10, and then the rotating shaft 5 can be rotationally limited by the first transmission gear 8.
