The following describes a roller shaft assembling and disassembling device according to an embodiment of the present invention with reference to fig. 1 to 4, including a roller frame folding plate 1, a support rod 2 and a roller assembly 3, where the roller frame folding plate 1 is a long groove structure with an open top surface;
the supporting rods 2 are arranged along the length direction of the roller unloading frame folded plate 1, all the supporting rods 2 are parallel to each other, and the supporting rods 2 penetrate through two side wall surfaces 11 of the roller unloading frame folded plate 1 and then are fixed on the roller unloading frame folded plate 1;
the roller unloading assemblies 3 correspond to the support rods 2 one by one, the roller unloading assemblies 3 are sleeved on the outer wall of the support rods 2 and rotate by taking the support rods 2 as rotating shafts, and the height of roller surfaces of the roller unloading assemblies 3 rotating to the highest point is higher than the height of the tops of two side wall surfaces 11 of the roller unloading frame folded plates 1.
In the roller shaft assembling and disassembling device, because the roller unloading frame folded plate 1 is in a long groove-shaped structure with an open top surface, when the roller unloading wheel assembly 3 is installed, an installation gap is not required to be specially formed for the roller unloading wheel assembly 3, meanwhile, because the bottom surface 12 of the roller unloading frame folded plate 1 is in a closed structure, the rigidity strength of the whole roller shaft assembling and disassembling device can be improved, at the moment, because the height of the roller surface of the roller unloading wheel assembly 3 rotating to the highest point is higher than the height of the tops of the two side wall surfaces 11 of the roller unloading frame folded plate 1, after the roller shaft 4 is placed in the roller shaft assembling and disassembling device, the roller shaft 4 is supported by the roller unloading wheel assembly 3 and does not touch the roller unloading frame folded plate 1, and the roller shaft 4 can be ensured to be smoothly conveyed to a frame of a conveying device. In addition, because the roller shaft assembling and disassembling device adopts a structure that the roller shaft assembling and disassembling device is directly connected with the supporting rod 2 in a rotating way, the arrangement of a bearing is cancelled, the problem of bearing locking can not occur, and the normal rotation of the roller shaft assembling and disassembling device 3 is ensured.

Compared with the rectangular groove arranged on the bottom surface 12, the bent edge of the inverted V-shaped groove 121 has large scale and large angle, so that the bending is relatively simple, and the bending quantity is relatively small. The inverted V-shaped groove 121 is used for enhancing the rigidity of the roller unloading frame folded plate 1, the ceramic roller with the length of more than three meters is heavy, and if the inverted V-shaped groove 121 is not arranged in the middle, the roller unloading assembly 3 deforms to possibly cause the rotation and the clamping of the roller 1.
It is noted that, as shown in fig. 3 and 4, the top portions of the side wall surfaces 11 of the roll-off shelf flaps 1 are each provided with a hem portion 13, the hem portion 13 is at the same height as the top portions of the side wall surfaces 11, the hem portion 13 is perpendicular to the side wall surfaces 11, and the hem portion 13 extends to the outside of the roll-off shelf flaps 1. The turning part 13 is arranged and can be bent outwards when the roller unloading frame folded plate 1 leaves a factory, so that the phenomenon that the edge of the roller unloading frame folded plate 1 is deformed inwards to block the roller unloading wheel assembly 3 when the roller unloading frame folded plate is used.
