Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber cloth processing, in particular to a carbon fiber cloth rolling machine. Background Art

[0002] Carbon fiber cloth winding machine is a machine used to wind carbon fiber cloth (or carbon fiber yarn) in the form of a roll. Carbon fiber cloth winding machine is usually used in the production process of carbon fiber products, such as carbon fiber composite materials, carbon fiber reinforced plastics, etc. The main working process includes cloth supply, winding device, tension control, automatic cutting and roll changing.

[0003] Most carbon fiber cloth winding machines include a winding device and a tension control device. The tension of the carbon fiber cloth is mainly affected by two factors. One is the speed at which the winding device winds the carbon fiber cloth, and the other is the tension control of the carbon fiber cloth by the tension control device. However, since the tension control device usually fixes the carbon fiber cloth unchanged, the speed of the carbon fiber cloth is limited, resulting in the speed of the carbon fiber cloth being able to be stabilized within a certain range. When the speed is too fast, the tension on the carbon fiber cloth will be increased.

[0004] In view of this, we propose a carbon fiber cloth rolling machine. Utility Model Content

A spring is arranged between the first roller and the second roller and between the limit frame and the mounting groove. When winding, the spring is compressed according to the winding speed of the winding group, so as to adjust the position of the second roller relative to the carbon fiber cloth, thereby realizing automatic tension balance.

[0007] Therefore, the utility model provides a carbon fiber cloth rolling machine, including a cloth supply group, a stabilizing group and a winding group, the stabilizing group includes a placing table, an automatic tensioning group is provided on the side of the placing table close to the winding group, a first roller and a second roller are provided in the automatic tensioning group, and the cloth of the cloth supply group passes through the gap between the first roller and the second roller from the first roller, passes out from under the second roller and is fixed on the winding group.

[0008] As a further improvement of the technical solution, a mounting groove is symmetrically provided on one side of the placement table, and the automatic tensioning assembly is arranged in the mounting groove.

[0009] As a further improvement of the technical solution, the automatic tensioning group further includes a limiting frame, and a second spring is provided between one end of the limiting frame and the mounting groove.

[0011] As a further improvement of the technical solution, both ends of the second roller are rotatably connected to an end of the limiting frame away from the first roller, and a first spring is provided between the first roller and the second roller.

[0023] Most carbon fiber cloth winding machines include a winding device and a tension control device. The tension of the carbon fiber cloth is mainly affected by two factors. One is the speed at which the winding device winds the carbon fiber cloth, and the other is the tension control of the carbon fiber cloth by the tension control device. However, since the tension control device usually fixes the carbon fiber cloth unchanged, the speed of the carbon fiber cloth is limited, resulting in the speed of the carbon fiber cloth being able to be stabilized within a certain range. When the speed is too fast, the tension on the carbon fiber cloth will be increased.

[0024] like Figure 1-Figure 4 As shown, the present embodiment provides a carbon fiber cloth winding machine, including a cloth supply group 100, a stabilizing group 200 and a winding group 300, the stabilizing group 200 includes a placing table 210, and an automatic tensioning group 220 is provided on one side of the placing table 210 close to the winding group 300. Considering that the carbon fiber cloth is synchronously limited and leveled, a first roller 221 and a second roller 222 are provided in the automatic tensioning group 220, and the cloth of the cloth supply group 100 passes through the gap between the first roller 221 and the second roller 222 from the first roller 221, passes from under the second roller 222 and is fixed on the winding group 300.

[0025] The improvement of this embodiment is that an automatic tensioning group 220 is arranged on one side of the placement table 210, and the automatic tensioning group 220 is used to automatically tension the carbon fiber cloth passing through the gap between the first roller 221 and the second roller 222, so that the carbon fiber cloth can be simultaneously limited and leveled when winding.

[0026] Considering that the speed changes during winding, the automatic tensioning group 220 changes with the speed change so that the total tension of the carbon fiber cloth is maintained within a certain range. Therefore, the second embodiment of the utility model is shown.

[0027] A mounting groove 211 is symmetrically provided on one side of the placement table 210, and the automatic tensioning group 220 is arranged in the mounting groove 211. The automatic tensioning group 220 also includes a limiting frame 223, and a second spring 225 is provided between one end of the limiting frame 223 and the mounting groove 211. A through groove is provided in the limiting frame 223, and the two ends of the first roller 221 pass through the through groove of the limiting frame 223 and the fixing plates on both sides of the placement table 210, so that the limiting frame 223 rotates in the mounting groove 211, and the two ends of the second roller 222 are rotatably connected to the limiting frame 22 The first roller 221 is at one end away from the first roller 221, and a first spring 224 is provided between the first roller 221 and the second roller 222. By providing the spring between the first roller 221 and the second roller 222 and between the limit frame 223 and the mounting groove 211, when winding, according to the winding speed of the winding group 300, the spring is compressed to adjust the position of the second roller 222 relative to the carbon fiber cloth, so as to achieve automatic tension balance. The first roller 221 and the second roller 222 are both provided with a fixed shaft, and a rotating sleeve is sleeved on the outer side of the fixed shaft.

[0028] In summary, the working principle of this solution is as follows:

[0029] The carbon fiber cloth is pulled out from the cloth supply group 100, placed on the placement table 210, passed through the gap between the first roller 221 and the second roller 222 from the first roller 221, passed under the second roller 222 and fixed on the winding group 300, and the winding group 300 is started. When the winding group 300 winds up the carbon fiber cloth, the winding group 300 and the cloth supply group 100 will generate tension on the carbon fiber cloth, and when the carbon fiber cloth passes through the gap between the first roller 221 and the second roller 222, the second roller 222 will rotate. There is another tension due to the self-gravity of 22 and the winding group 300 on the carbon fiber cloth, and the two tensions together constitute the total tension. When the winding speed of the winding group 300 is increased, the tension of the winding group 300 and the cloth supply group 100 on the carbon fiber cloth becomes larger, and the first spring 224 and the second spring 225 are compressed, so that the position of the second roller 222 is changed, resulting in the self-gravity of the second roller 222 and the tension of the winding group 300 on the carbon fiber cloth becoming smaller, so that the total tension together is maintained within a certain range.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
