Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to a flexible graphite paper calender. Background Art

[0002] Flexible graphite paper is a graphite product made by rolling high-carbon flake graphite after chemical treatment and high-temperature expansion. Flexible graphite paper offers properties such as high-temperature resistance (operating temperatures can reach up to 400°C and as low as -40°C), low-temperature resistance, corrosion resistance, resistance to various media, excellent self-lubrication, low friction coefficient, and exceptional flexibility and resilience. Furthermore, flexible graphite paper is lightweight and easy to use, allowing it to be smoothly adhered to any flat or curved surface.

[0003] The processing of flexible graphite paper involves the steps of material leveling and calendering. After being evenly distributed by the vibrating screen, the expanded graphite falls into the feeder, is flattened by the ratchet roller, and then sent to the roller via the conveyor belt for calendering to form a thicker graphite paper blank. The graphite paper blank is then calendered by multiple pressure rollers and wound into a roll, which becomes the finished graphite paper.

[0004] When the graphite material is rolled by the roller, the graphite paper is rolled thinner, but the edges of the graphite paper are mostly wavy. The edges of the graphite paper need to be cut separately, making it difficult to cut and recycle this part of the graphite material during the cutting process, resulting in low efficiency in the cutting and recycling of graphite paper. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a flexible graphite paper calender to solve the problem that the edges of the graphite paper need to be cut separately, resulting in low efficiency in cutting and recycling the edges of the graphite paper.

[0006] In order to achieve the above-mentioned object, the basic scheme of the present invention is as follows: a flexible graphite paper calender, comprising a calender body, the calender body comprising a mounting frame, a first calender roller, and a second calender roller that can be raised and lowered, wherein the roller surface of the first calender roller can abut against the roller surface of the second calender roller, and further comprising:

[0007] The edge cutting recovery box is installed on the mounting frame, the edge cutting recovery box is opposite to the end face of the roller surface of the first calendering roller, and the cutting part of the edge cutting recovery box is in contact with the opposite part of the roller surface of the first calendering roller and the second calendering roller.

[0008] The technical principle of the utility model is: when a flexible graphite paper calender is used to calender graphite paper, the graphite paper also passes through the edge cutting recovery box in sequence. When the edge of the calendered graphite paper extends to the outside of the end faces of the first calendering roller and the second calendering roller, the edge of the graphite paper will pass through the edge cutting recovery box. The cutting part of the edge cutting recovery box cuts the excess edge of the graphite paper. At the same time, the cut graphite material can be stored in the edge cutting recovery box to realize the cutting, guiding and collection of the excess graphite material. The graphite paper is calendered simultaneously, which improves the cutting, guiding and collection efficiency of the excess graphite material, reduces the cutting steps of the graphite paper, and improves the processing efficiency of the graphite paper.

[0009] Furthermore, an incomplete opening is provided on one side of the edge cutting recovery box close to the end face of the first calendering roller, and the incomplete opening is opposite to the conveying direction of the graphite paper. The incomplete opening of the edge cutting recovery box is blade-shaped on one side close to the end face of the first calendering roller.

[0010] Through the above setting, when cutting the edge of the graphite paper, the edge of the graphite paper will be embedded in the edge cutting recovery box through the incomplete opening, which makes it easier for the edge of the graphite paper to contact the blade-shaped part of the edge cutting recovery box, thereby achieving comprehensive cutting of the edge of the graphite paper and improving the cutting accuracy and efficiency of the edge of the graphite paper.

[0011] Furthermore, the cross-sectional profile of the incomplete opening of the edge-cut recovery box is "L"-shaped.

[0012] Through the above arrangement, the edge of the graphite paper can be horizontally inserted into the edge cutting recovery box through the incomplete "L"-shaped opening, avoiding obstruction of the edge of the graphite paper by the corner of the cutting recovery box, thereby facilitating comprehensive cutting of the edge of the graphite paper.

[0013] Furthermore, one side of the edge cutting recovery box close to the end face of the first calendering roller is in contact with the end faces of the first calendering roller and the second calendering roller, and the blade-shaped portion of the edge cutting recovery box is in the shape of an inclined surface inclined toward the edge cutting recovery box.

[0014] Through the above arrangement, the beveled portion of the edge cutting recovery box guides the excess graphite material, so that the cut graphite material can be accurately collected into the edge cutting recovery box, making it easier to collect the graphite material.

[0015] Furthermore, one end of the edge cutting recovery box away from the first calendering roller extends outside the mounting frame, and the edge cutting recovery box is detachably connected to the mounting frame.

[0016] Through the above arrangement, it is convenient to hold the edge cutting recovery box from the end of the edge cutting recovery box located outside the mounting frame, and it is convenient to disassemble and assemble the edge cutting recovery box on the mounting frame.

[0017] Furthermore, a collecting box is vertically and detachably mounted on one end of the edge cutting recovery box away from the first calendering roller, and the collecting box is located at the lower side of the edge cutting recovery box.

[0018] Through the above-mentioned setting, when the graphite material accumulates at the collection box, the graphite material can automatically fall into the collection box. When a large amount of graphite material is collected in the collection box, the collection box is disassembled, the graphite material in the collection box is transferred and recovered, and then the collection box is installed on the edge cutting recovery box to improve the transfer and recovery efficiency of the graphite material.

[0019] Furthermore, the number of the edge cutting recovery boxes is two, and the two edge cutting recovery boxes are located on both ends of the first calendering roller and the second calendering roller.

[0020] Through the above arrangement, both sides of the graphite paper can be cut synchronously, so that the cutting of the graphite paper is comprehensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] This embodiment is basically as Figure 1 、 Figure 2 and Figure 3 As shown, the embodiment of the present invention provides a flexible graphite paper calender, including a calender body and an edge cutting recovery box 20, as shown in FIG. Figure 1 As shown, the calender body includes a mounting frame 101, a first calendering roller 102 and a second calendering roller 103 that can be raised and lowered. The roller surface of the first calendering roller 102 can be against the roller surface of the second calendering roller 103.

[0027] like Figure 1 and Figure 2As shown, the edge cutting recovery box 20 is in the shape of a rectangular parallelepiped, and the lower side of the edge cutting recovery box 20 is detachably mounted on the mounting frame 101 by bolts, and the end of the edge cutting recovery box 20 is opposite to the end face of the roller surface of the first calendering roller 102, and the side of the edge cutting recovery box 20 close to the end face of the first calendering roller 102 is in contact with the end faces of the first calendering roller 102 and the second calendering roller 103; at the same time, an incomplete opening 201 is provided at the side of the edge cutting recovery box 20 close to the end face of the first calendering roller 102, and the cross-sectional profile of the incomplete opening 201 of the edge cutting recovery box 20 is "L"-shaped; the incomplete opening 201 is opposite to the conveying direction of the graphite paper.

[0028] At the same time, if Figure 2 and 3 As shown, the incomplete opening 201 of the edge cutting recovery box 20 is blade-shaped at one side close to the end surface of the first calendering roller 102 , and the blade-shaped portion of the edge cutting recovery box 20 is in an inclined plane inclined toward the edge cutting recovery box 20 .

[0029] like Figure 1 As shown, one end of the edge cutting recovery box 20 away from the first calendering roller 102 extends to the outside of the mounting frame 101 , the edge cutting recovery box 20 is plug-in and snap-connected to the mounting frame 101 , and the collection box 30 is located at the lower side of the edge cutting recovery box 20 .
