Description

Technical Field

[0001] This utility model relates to the field of graphite paper calendering technology, and in particular to a graphite paper calendering device. Background Technology

[0002] Graphite paper is made by chemically treating high-carbon flake graphite and expanding and rolling it at high temperature. It is widely used in the dynamic and static sealing of machines, pipes, pumps and valves in industries such as power, petroleum, chemical, instrumentation, machinery and diamond. It is an ideal new type of sealing material to replace traditional seals such as rubber, fluoroplastics and asbestos. Calendering equipment is used in the production of graphite paper. Calendering is one of the important basic processes in the processing of polymer materials.

[0003] Existing patent number CN216466349U discloses a novel flexible graphite paper calendering device. Through the setting of the cleaning component, when the graphite paper passes through the protective shell, two sets of brushes will simultaneously clean the upper and lower parts of the graphite paper. At the end of the graphite paper calendering, the dirt on the top of the graphite paper will fall into the collection box under the action of gravity, thereby achieving the cleaning of dirt on the surface of the graphite paper. Through the setting of the pressing component, the graphite paper can be pressed inside the protective shell, so that the graphite flakes accumulated on the surface of the graphite paper can extend on the surface of the graphite paper and thus adhere to the surface of the graphite paper.

[0004] The above solution has the following problems during implementation: When calendering graphite paper of different thicknesses is required, the device cannot adjust the gap between the two calendering rollers. If the gap between the two calendering rollers is too small, the graphite paper will be excessively deformed under pressure. If the gap between the two calendering rollers is too large, the graphite paper cannot obtain sufficient strength for plasticity, thus reducing the effectiveness of the device. Furthermore, although the dirt on the brush will fall into the collection box under the action of gravity, dirt will still remain on the brush. The device cannot disassemble the brush, so that a large amount of dirt will adhere to the brush during long-term use, reducing the cleaning effect of the device. Utility Model Content

[0005] In view of the fact that the above-mentioned device cannot adjust the gap between the two calendering rollers and that dirt will still remain on the brush, and the device cannot disassemble the brush, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a graphite paper calendering device, including a base, a mounting frame connected to the base, two support plates connected to one side of the mounting frame, a drive rod connected to the support plates, two calendering rollers arranged inside the mounting frame, and the two calendering rollers passing through the mounting frame on the side near the support plates, a U-shaped plate connected to the base, a cleaning brush arranged inside the U-shaped plate, a disassembly mechanism arranged on one side of the cleaning brush for disassembling the cleaning brush, and a lifting mechanism arranged inside the mounting frame for moving the upper calendering roller;

[0007] The lifting mechanism includes a first drive motor mounted on a support plate, with the output end of the first drive motor passing through the support plate and connected to one side of a drive rod. A positioning block is connected to the drive rod. Two sets of bevel gears are provided at the positions where the drive rod approaches the calendering roll. One bevel gear is mounted on the drive rod, and the other bevel gear is mounted on the calendering roll. The uppermost bevel gear on the drive rod has a sliding groove inside, and the sliding groove is connected to the positioning block. A screw is screwed onto the top of the mounting frame, and the screw passes through the top of the mounting frame. A connecting frame is connected to one side of the screw passing through the mounting frame, and the connecting frame is connected to both the calendering roll and the drive rod.

[0008] In a preferred embodiment of the graphite paper calendering device of this utility model, two fixing plates are connected to the base, a winding roller is connected to the fixing plate, and one side of the winding roller passes through the fixing plate. A second drive motor is connected to the side of the winding roller that passes through the fixing plate.

[0009] In a preferred embodiment of the graphite paper calendering device of this utility model, two rotating rods are connected to the front side of the U-shaped plate, and one side of the rotating rod passes through the U-shaped plate. The side of the rotating rod passing through the U-shaped plate is rectangular. A first belt is sleeved between the winding roller and one of the rotating rods, and a second belt is sleeved between the two rotating rods. A cleaning brush is connected to the side of the rotating rod passing through the U-shaped plate, and the side of the cleaning brush connected to the rotating rod is rectangular.

[0010] In a preferred embodiment of the graphite paper calendering device of this utility model, the disassembly mechanism includes a support column connected to the side of the U-shaped plate away from the rotating rod, a groove is provided in the support column, a limiting plate is connected in the groove, a locking block is connected to the limiting plate, a slot is provided in the cleaning brush, and the size of the slot is adapted to the size of the locking block, and a spring is connected to the bottom of the limiting plate, and the side of the spring away from the limiting plate is connected to the groove.

[0011] In a preferred embodiment of the graphite paper calendering device of this utility model, a collection box is installed on the base and the collection box is located below the cleaning brush.

[0012] In a preferred embodiment of the graphite paper calendering device of this utility model, two telescopic rods are connected to the top of the mounting frame, and the side of the telescopic rods away from the mounting frame is connected to the connecting frame.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Please see Figures 1 to 3 This is the first embodiment of the present invention, providing a technical solution: a graphite paper calendering device, including a base 1, a mounting frame 2 fixedly connected to the base 1, two support plates 3 fixedly connected to one side of the mounting frame 2, a drive rod 4 rotatably connected to the support plates 3, two calendering rollers 5 inside the mounting frame 2 for calendering graphite paper, the upper calendering roller 5 slidably connected to the mounting frame 2, the lower calendering roller 5 rotatably connected to the mounting frame 2, and the two calendering rollers 5 passing through the mounting frame 2 on the side near the support plates 3, a U-shaped plate 9 fixedly connected to the base 1, a cleaning brush 902 inside the U-shaped plate 9, a disassembly mechanism on one side of the cleaning brush 902 for disassembling the cleaning brush 902, and a lifting mechanism inside the mounting frame 2 for moving the upper calendering roller 5;

[0026] The lifting mechanism includes a primary drive motor 501 mounted on the support plate 3. The output end of the primary drive motor 501 passes through the support plate 3 and is fixedly connected to one side of the drive rod 4. Starting the primary drive motor 501 drives the drive rod 4 to rotate. A positioning block 502 is fixedly connected to the drive rod 4. Two sets of bevel gears 503 are provided at the positions where the drive rod 4 approaches the calendering roller 5. One bevel gear 503 is mounted on the drive rod 4, and the other bevel gear 503 is mounted on the calendering roller 5. The two bevel gears 503 are meshed together. The uppermost bevel gear 503 of the drive rod 4 has a sliding groove inside, and the groove is slidably connected to the positioning block 502. Under the limitation of the positioning block 502, the drive rod 4 rotates, driving the bevel gear mounted on the drive rod 4. The wheel 503 rotates, thereby engaging with the bevel gear 503 mounted on the calendering roller 5, driving the calendering roller 5 to rotate and calender the graphite paper. A screw 504 is screwed onto the top of the mounting frame 2, and the screw 504 passes through the top of the mounting frame 2. A handle is fixedly connected to the top of the screw 504. The screw 504 is manually rotated to move. A connecting frame 505 is rotatably connected to one side of the screw 504 that passes through the mounting frame 2. The connecting frame 505 is rotatably connected to the calendering roller 5 and the drive rod 4 respectively. When the screw 504 moves, it drives the connecting frame 505 to move, thereby causing the bevel gear 503 to slide on the positioning block 502, which in turn drives the calendering roller 5 above to move, thus adjusting the gap between the two calendering rollers 5.

[0027] Two telescopic rods 13 are fixedly connected to the top of the mounting bracket 2. The side of the telescopic rod 13 away from the mounting bracket 2 is fixedly connected to the connecting bracket 505. When the connecting bracket 505 moves, it pulls the telescopic rod 13 to stretch or retract. The telescopic rod 13 provides stability for the movement of the connecting bracket 505.

[0028] A guide mechanism 12 is fixedly installed on the base 1. The guide mechanism 12 includes a guide plate and a guide column. The guide plate is fixedly connected to the base 1, and the guide column is rotatably connected to the guide plate. The graphite paper passes through the guide column, and the guide column provides guidance for the movement of the graphite paper.

[0029] In use, by manually rotating the screw 504, the screw 504 is moved on the mounting bracket 2, thereby moving the connecting bracket 505 up and down, which in turn causes the bevel gear 503 to slide on the positioning block 502, so that the screw 504 moves up and down and drives the upper calendering roller 5 to move, thereby adjusting the gap between the two calendering rollers 5.

[0030] Furthermore, by starting the No. 1 drive motor 501, the drive rod 4 is driven to rotate. Under the limit of the positioning block 502, the bevel gear 503 installed on the drive rod 4 is driven to rotate, thereby cooperating with the bevel gear 503 installed on the calendering roller 5 to drive the calendering roller 5 to rotate and perform calendering treatment on the graphite paper.

[0031] Example 2

[0032] Please see Figures 3 to 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: two fixed plates 6 are fixedly connected to the base 1, and a take-up roller 7 is rotatably connected to the fixed plate 6. One side of the take-up roller 7 passes through the fixed plate 6. A second drive motor 8 is fixedly connected to the side of the take-up roller 7 that passes through the fixed plate 6. One side of the graphite paper passes through the guide post, then through the two cleaning brushes 902, then through the two calendering rollers 5, and finally is fixed to the take-up roller 7. The second drive motor 8 is started to drive the take-up roller 7 to rotate, thereby moving the graphite paper.

[0033] Two rotating rods 901 are rotatably connected to the front side of the U-shaped plate 9, and one side of the rotating rod 901 is set through the U-shaped plate 9. The rotating rod 901 is rectangular in shape on the side of the rotating rod 901 that is passed through the U-shaped plate 9. A first belt is sleeved between the take-up roller 7 and one of the rotating rods 901. The rotation of the take-up roller 7, in conjunction with the first belt, drives one of the rotating rods 901 to rotate. A second belt is sleeved between the two rotating rods 901. The rotation of one of the rotating rods 901, in conjunction with the second belt, drives the other rotating rod 901 to rotate. A cleaning brush 902 is slidably connected to the side of the rotating rod 901 that is passed through the U-shaped plate 9. The side of the cleaning brush 902 that is slidably connected to the rotating rod 901 is rectangular in shape. The rotation of the rotating rod 901 drives the cleaning brush 902 to rotate.

[0034] The disassembly mechanism includes a support column 10 rotatably connected to the side of the U-shaped plate 9 away from the rotating rod 901. A groove is formed in the support column 10, and a limit plate 1001 is slidably connected within the groove. Manually pressing the limit plate 1001 causes it to slide into the groove. A locking block 1002 is fixedly connected to the limit plate 1001. A slot is formed in the cleaning brush 902, and the size of the slot matches the size of the locking block 1002. Moving the limit plate 1001 causes the locking block 1002 to move out of the slot in the cleaning brush 902. Then, the cleaning brush 902 is pulled towards one side of the support column 10 until the rectangular end of the cleaning brush 902 moves out of the rotating rod 901. The limiting plate 1001 and the locking block 1002 are compressed into the groove of the support column 10. At this time, there is a gap between the inner wall of the cleaning brush 902 and the support column 10. Then, the cleaning brush 902 can be pulled out from the support column 10 by tilting it slightly, so as to disassemble the cleaning brush 902 and clean the dirt remaining in the cleaning brush 902, thereby improving the use effect of the device. The bottom of the limiting plate 1001 is fixedly connected to the spring 1003, and the side of the spring 1003 away from the limiting plate 1001 is fixedly connected to the groove. The spring 1003 is set so that when the limiting plate 1001 is manually released, the locking block 1002 is driven to engage in the slot under the reset force of the spring 1003.

[0035] A collection box 11 is installed on the base 1, and the collection box 11 is located below the cleaning brush 902. The cleaning brush 902 rotates to clean the dirt on the graphite paper. The dirt on the cleaning brush 902 below falls onto the cleaning brush 902. After the graphite paper is calendered, the dirt on the cleaning brush 902 above falls into the collection box 11 under the action of gravity.

[0036] In use, by manually pressing the limiting plate 1001, the limiting plate 1001 is slid into the groove. When the locking block 1002 moves out of the slot of the cleaning brush 902, the cleaning brush 902 is pulled towards the support column 10, so that the rectangular end of the cleaning brush 902 moves from the inside of the rotating rod 901. Since the limiting plate 1001 and the locking block 1002 are compressed into the groove of the support column 10 at this time, there is a gap between the inner wall of the cleaning brush 902 and the support column 10. Then, the cleaning brush 902 is slightly tilted and pulled out from the support column 10 to disassemble the cleaning brush 902.

[0037] The remaining structure is the same as that in Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
