DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] like Figure 1 As shown, the utility model provides a graphite carbon felt hole opening device, including an unwinding roller 1, a hole opening mechanism 2 and a reeling roller 3 which are arranged in sequence, the unwinding roller 1 is used to unwind the rolled graphite carbon felt, the reeling roller 3 is used to reel the graphite carbon felt after the holes are opened, the unwinding roller 1 and the reeling roller 3 are used together to continuously unwind the rolled graphite carbon felt, which is convenient for realizing continuous hole opening of the graphite carbon felt at the hole opening mechanism 2. In addition, the unwinding roller 1 is used together with the unwinding roller bracket 4, so that the rotation of the unwinding roller 1 is more stable, the unwinding roller 1 is rotatable and detachably arranged on the unwinding roller bracket 4, which is convenient for the unwinding roller 1 to unwind the rolled graphite carbon felt, and the unwinding roller 1 is detachably connected to the unwinding roller bracket 4, which is convenient for the unwinding roller 1 to maintain or replace. At the same time, the winding roller 3 is used in conjunction with the winding roller bracket 5, making the winding process more stable and reliable. The winding roller 3 is rotatable and detachably arranged on the winding roller bracket 5, which is convenient for the winding roller 3 to wind up the graphite carbon felt with the holes opened, and the winding roller 3 is detachably connected to the winding roller bracket 5, which is convenient for the maintenance or replacement of the winding roller 3. In addition, a plurality of tensioning rollers 6 are arranged between the unwinding roller 1 and the winding roller 3. The tensioning roller 6 can effectively tension the graphite carbon felt to ensure that it remains flat during the transmission process and avoid processing quality problems caused by relaxation. At the same time, the tensioning roller 6 can also adjust the steering and angle of the graphite carbon felt, making the entire processing flow smoother and more efficient.

[0031] like Figure 1 As shown, in this embodiment, the hole opening mechanism 2 includes an upper pressure roller 21 and a lower pressure roller 22 which are rotatably arranged, and the upper pressure roller 21 and the lower pressure roller 22 are arranged opposite to each other, wherein the upper pressure roller 21 is located on the top of the lower pressure roller 22, so that the upper pressure roller 21 and the lower pressure roller 22 can cooperate with each other, and the graphite carbon felt passes between the upper pressure roller 21 and the lower pressure roller 22 to realize the hole opening of the graphite carbon felt.

[0032] like Figures 1 to 3 As shown, in this embodiment, the upper pressing roller 21 is evenly distributed with a plurality of protruding pressing teeth 211, and the lower pressing roller 22 is provided with a plurality of tooth grooves 221 corresponding to the pressing teeth 211, and the shape and size of the tooth grooves 221 match the pressing teeth 211, so that when the graphite carbon felt passes between the upper pressing roller 21 and the lower pressing roller 22, the pressing teeth 211 can accurately penetrate into the tooth grooves 221. When the graphite carbon felt passes between the upper pressing roller 21 and the lower pressing roller 22, the pressing teeth 211 penetrate into the tooth grooves 221 to make holes in the graphite carbon felt, that is, the pressing teeth 211 and the tooth grooves 221 cooperate with each other, and the edges of the two form a blade for making holes in the graphite carbon felt, so as to cut and make holes in the graphite carbon felt. Due to the precise matching of the pressing teeth 211 and the tooth grooves 221, the holes made on the graphite carbon felt are not only regular in shape, but also consistent in size, which greatly improves the quality and stability of the holes. In addition, the tooth groove 221 can temporarily accommodate the slag after the graphite carbon felt is opened. During the cutting process, part of the graphite carbon felt material will be cut off to form slag, and the tooth groove 221 can temporarily accommodate the slag therein, thereby avoiding the influence of the slag on the opening process.

[0033] In the present embodiment, the pressing teeth 211 are threadedly connected to the upper pressing roller 21. Specifically, a plurality of mounting holes may be provided on the upper pressing roller 21, and a threaded column may be provided at the inner end of the pressing teeth 211, and the inner end of the pressing teeth 211 is threadedly connected to the mounting holes. In actual operation, the staff may rotate the threaded column of the pressing teeth 211 as needed to adjust the height of the outer end of the pressing teeth 211 exposed from the surface of the upper pressing roller 21, so as to adapt to the requirements for opening holes of graphite carbon felt of different thicknesses. For example, thicker graphite carbon felt requires deeper pressing teeth 211 for opening holes, while thinner graphite carbon felt may use shallower pressing teeth 211. In this way, the applicability of the utility model is greatly improved, and it can meet the processing requirements of more types of graphite carbon felt.

[0034] like Figure 1 As shown, in this embodiment, the cross-sectional shape of the pressing tooth 211 is columnar, and the cross-sectional shape of the pressing tooth 211 can be designed to be cylindrical, that is, a circular hole is opened on the surface of the graphite carbon felt. Of course, the cross-sectional shape of the pressing tooth 211 can also be designed to be rectangular or prism-shaped. In actual design, the cross-sectional shape of the pressing tooth 211 can be set according to the requirements of the opening of the graphite carbon felt.

[0035] like Figures 1 to 3 As shown, in this embodiment, each tooth groove 221 is provided with a top block 222, and the top block 222 is slidably connected with the tooth groove 221, so as to eject the slag material after the graphite carbon felt in the tooth groove 221 is opened. In addition, a spring 223 is provided between the tooth groove 221 and the top block 222. When the pressure tooth 211 cooperates with the tooth groove 221 to open a hole in the graphite carbon felt, the top block 222 is squeezed down by the pressure tooth 211, and the spring 223 is also squeezed and deformed, thereby leaving enough space for the slag material generated after the graphite carbon felt is opened. Once the pressure tooth 211 completes the hole opening operation and leaves the tooth groove 221, the spring 223 will quickly reset. Under the elastic force of the spring 223, the top block 222 will move outward, push and eject the graphite carbon felt slag material accumulated in the tooth groove 221, which not only ensures the cleanliness of the tooth groove 221, but also prepares for the next hole opening operation. In addition, there are multiple springs 223 in each tooth groove 221, and two springs 223 can be set in each tooth groove 221, so that the top block 222 is evenly stressed and the top block 222 can quickly push out the slag after the black carbon felt is opened. Of course, in actual design, the number of springs 223 in each tooth groove 221 can be designed according to actual needs.

[0036] like Figure 3 As shown, in this embodiment, the outer surface of the top block 222 is an arc surface that matches the outer surface of the lower pressure roller 22, which makes it convenient for the lower pressure roller 22 to form a complete surface, and also makes it convenient for the graphite carbon felt to always be supported during the hole-making process. Specifically, when the graphite carbon felt is performing the hole-making operation under the cooperation of the pressure teeth 211 and the tooth grooves 221, the top block 222 will play a key supporting role. Since the outer surface of the top block 222 matches the outer surface of the lower pressure roller 22, the graphite carbon felt can always be stably supported when passing through, avoiding the hole-making quality problems caused by uneven force, which not only improves the accuracy and consistency of the hole-making, but also extends the service life of the device.

[0037] like Figures 4 to 5 As shown, in another embodiment, the outer surface of the top block 222 can be designed to be a plane, which is convenient for processing the top block 222 and reduces production costs. Of course, in actual design, the shape of the outer surface of the top block 222 can be designed according to actual needs.

[0038] When the utility model is in use, the rolled graphite carbon felt is placed on the unwinding roller 1 for unwinding, so that the graphite carbon felt is tensioned by the tensioning roller 6, and the graphite carbon felt passes between the upper pressing roller 21 and the lower pressing roller 22, and the pressing teeth 211 of the upper pressing roller 21 accurately penetrate into the tooth grooves 221 of the lower pressing roller 22, thereby forming regular holes on the graphite carbon felt. The utility model has a simple structure, can improve the hole opening efficiency of the graphite carbon felt, ensure that the specifications of the holes opened on the graphite carbon felt are consistent, the hole opening quality is stable, and manpower is greatly saved.
