Description

Technical Field

[0001] This utility model relates to the field of carbon fiber roller technology, and specifically to a novel carbon fiber roller core. Background Technology

[0002] Carbon fiber roller cores are roller core structures made of carbon fiber material, used in equipment such as rolls or winding rollers in industries such as textiles, printing, and composite materials. Compared with traditional roller core materials (such as steel and aluminum), carbon fiber roller cores have the advantages of being lightweight and high-strength. Therefore, using carbon fiber roller cores can reduce the self-weight of the roller core, thereby reducing power transmission and machine load.

[0003] While carbon fiber materials possess high stiffness and resistance to deformation, exhibiting superior deformation performance compared to other materials, if the carbon fiber roller core is subjected to forces exceeding its load-bearing capacity, it may undergo elastic or plastic deformation. Consequently, existing carbon fiber rollers often become unusable due to deformation after prolonged use, necessitating replacement. However, most existing carbon fiber rollers are fixed structures, making disassembly and assembly inconvenient. Consequently, when a carbon fiber roller is damaged, it is difficult to recycle and reuse the functional structural components, thus presenting a drawback.

[0004] In conclusion, it is necessary to invent a new type of carbon fiber roller core. Utility Model Content

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See attached document Figures 1-4 This utility model provides a novel carbon fiber roller core, comprising an outer roller body 100, which includes an outer wear-resistant layer 110, which may be diamond-coated. A polypropylene film layer 120 is fixed to the inner wall of the outer wear-resistant layer 110, and a reinforcing layer 130 is fixed to the inner wall of the polypropylene film layer 120. The reinforcing layer 130 may be made of honeycomb reinforcing plate. A carbon fiber layer 140 is fixed to the inner wall of the reinforcing layer 130. The composite layers of the outer roller body 100 are fixed together using AB adhesive. A connecting inner liner layer 330 is fixed to the inner wall of the carbon fiber layer 140, serving to fix it to the inner wall of the carbon fiber layer 140 and also replacing the end of the carbon fiber layer 140 and the tensioning rod 320. For fixation, a roller core body 300 is provided at the center of the inner wall of the inner lining layer 330. Both ends of the roller core body 300 are set as spline shafts, which can be splined to the inserted shaft socket 210, so that the connecting shaft 200 can drive the roller core body 300 to rotate through the shaft socket 210. Annular sleeves 310 are fixedly fitted on the outer wall side of the roller core body 300. Multiple annular sleeves 310 are evenly arranged in a strip array. A clamping rod 320 is fixed on the outer wall side of the annular sleeve 310. Multiple clamping rods 320 are fixed on the outer wall side of the annular sleeve 310 in an annular array. The end of the clamping rod 320 away from the annular sleeve 310 is fixedly connected to the inner wall side of the inner lining layer 330. The annular sleeves 310 and clamping rods 320 can enhance the internal structural strength of the carbon fiber roller core.

[0024] Both sides of the outer wall of the outer layer 100 of the roller are provided with sealing side sealing plates 220. The inner wall side of the side sealing plate 220 and the corresponding position of the outer layer 100 of the roller are fixed with reinforcing rods 221. The outer wall of the reinforcing rods 221 is fixedly connected to the inner wall side of the outer layer 100 of the roller. The polypropylene film layer 120, the reinforcing layer 130 and the carbon fiber layer 140 can be grooved and fitted with a metal layer to improve the fixing effect with the reinforcing rods 221, so that the side sealing plates 220 can be fixed to both sides of the outer layer 100 of the roller through the reinforcing rods 221. The outer wall of the opposite side of the two side sealing plates 220 is provided with connecting shafts 200.

[0025] The connecting shaft 200 is fixedly connected to the side end of the side sealing plate 220 via a fixing mechanism. The fixing mechanism includes a shaft socket 210. The end of the connecting shaft 200 near the outer layer 100 of the roller is fixedly connected to the outer wall side end of the shaft socket 210. A connecting slot is provided at the outer wall side end of the side sealing plate 220 and at the corresponding position of the shaft socket 210. The outer wall of the shaft socket 210 is inserted into the inner wall of the connecting slot. The shaft socket 210 is provided to replace the connecting shaft 200 for connecting to the side sealing plate 220. The shaft socket 210 has a spline groove at the connection point with the end of the roller core body 300. Both ends of the roller core body 300 are engaged with the spline groove. The side sealing plate 220 has a storage groove inside and outside the fixing slot. Multiple storage grooves are connected by a ring array. The roller core body 300 is arranged in a column. The inner wall of the storage slot is slidably connected with locking blocks 222. The insertion end of the shaft socket 210 is inserted into the outer wall of the locking block 222 through a square slot. The outer wall of the side sealing plate 220 and the corresponding position of the locking block 222 are threadedly connected with threaded fixing rods 223. The insertion end of the threaded fixing rod 223 is rotatably connected to the outer wall of the locking block 222. Specifically, when the operator inserts the shaft socket 210 into the fixing slot on the side of the side sealing plate 220 and engages it with the roller core body 300, the operator can rotate the threaded fixing rod 223 so that the threaded fixing rod 223 drives the locking block 222 to be inserted into the square slot on the outer wall of the shaft socket 210. In this way, the side sealing plate 220 and the outer wall of the shaft socket 210 can be fixedly connected.

[0026] The usage process of this utility model is as follows: those skilled in the art can first assemble the device according to the above description;

[0027] After the personnel have fixed the outer layer 100 of the roller, the side sealing plate 220 and the roller core body 300, they can take out the shaft socket 210 after raising and fixing the connecting shaft 200, and insert the shaft socket 210 into the fixing slot opened on the side end of the side sealing plate 220. After engaging with the roller core body 300, the personnel can rotate the threaded fixing rod 223 so that the threaded fixing rod 223 drives the locking block 222 to be inserted into the square groove opened on the outer wall of the shaft socket 210. In this way, the side sealing plate 220 and the outer wall of the shaft socket 210 can be fixedly connected. After completion, the personnel can place the carbon fiber roller core on the device for installation and use.

[0028] When the outer layer 100 of the roller is damaged, the personnel only need to remove the carbon fiber roller core and then rotate the threaded fixing rod 223 in the opposite direction to separate the locking block 222 from the shaft socket 210. Then the personnel can disassemble the shaft socket 210 and the side sealing plate 220, so that the shaft socket 210 and the side sealing plate 220 can be recycled and reused. At the same time, the side sealing plate 220 can also be removed from the side of the outer layer 100 of the roller for recycling.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
