[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7The glass fiber roller of the utility model comprises a cylinder 1, an axis core 2 inserted in the cylinder 1, two bearing seats 3 respectively arranged at the two ends of the cylinder 1, two bearings 4 respectively arranged in the two bearing seats 3, and a bearing removal assembly, the bearing removal assembly comprises a lead screw 7, a plurality of connecting rods 8 mounted on the lead screw 7, and a top plate 9 connecting the plurality of connecting rods 8. Both ends of the axis core 2 are provided with mounting holes 5 inside, both sides of the axis core 2 are provided with a plurality of through grooves 6, each through groove 6 penetrates into the mounting hole 5, each lead screw 7 is installed in the corresponding mounting hole 5, the connecting rod 8 is installed in the corresponding through groove 6, and nuts 10 matching the lead screw 7 are fixedly provided at both ends of the axis core 2. The lead screw 7 is rotated by a tool to make the top plate 9 move outward, and the top plate 9 is used to eject the bearing 4 from the bearing seat 3, thereby facilitating the disassembly of the bearing 4 and improving the maintenance efficiency of the roller.

[0025] Among them, the cylinder 1 is made of glass fiber material, which replaces the cylinder 1 made of metal materials such as iron in the past. Since the glass fiber material is a lightweight and high-strength material, the cylinder 1 of the utility model is made of glass fiber material, which not only has good wear resistance and high strength, but also is lighter as a whole, which can reduce the load and energy consumption of the conveying system and can be better applied to various occasions. In addition, since the glass fiber material has good corrosion resistance, the cylinder 1 made of glass fiber material also has good corrosion resistance, which can make the whole more durable.

[0026] Wherein, sealing covers for sealing the bearings 4 are installed in the openings of the two bearing seats 3 .

[0027] A screw block 11 is fixedly provided at the end of each lead screw 7, so that the screw block 11 can be screwed with a wrench.

[0028] The lead screw 7 is provided with a socket penetrating the lead screw 7 , and a detachable rotating rod (not shown in the figure) is inserted into the socket, so that the lead screw 7 can be rotated conveniently by utilizing the rotating rod.

[0029] In summary, when installing the bearing of the fiberglass roller, the lead screw is rotated to place the top plate inside the bearing seat, and then the bearing is pushed into the bearing seat;

[0030] When disassembling the bearing, the screw 7 is rotated by a tool to move the top plate 9 outward, and the bearing 4 is pushed out of the bearing seat 3 by the top plate 9, thereby facilitating the disassembly of the bearing 4 and improving the maintenance efficiency of the roller.
