Description

Technical Field

[0001] This utility model relates to the field of graphite soft felt production technology, specifically a thickness detection device for graphite soft felt production. Background Technology

[0002] Graphite soft felt is a flexible felt-like material made from natural or artificial graphite through special processes. It is lightweight, high temperature resistant, has low thermal conductivity, and good flexibility. It can maintain stable performance in high temperature environments and is widely used in thermal insulation, sealing, and high temperature protection in metallurgy, chemical industry, new energy and other fields.

[0003] Existing thickness detection devices used in graphite felt production cannot limit the movement of the graphite felt during use, causing it to deviate from the thickness measuring device during transmission, leading to equipment shutdown. Furthermore, they cannot mark thinner or thicker sections of the graphite felt, making it difficult for users to effectively distinguish between them. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a thickness detection device for the production of graphite soft felt, which has the advantages of graphite soft felt positioning and automatic marking, and solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a thickness detection device for the production of graphite soft felt, comprising a base, a vertical plate fixedly installed on the top of the base, a winding motor fixedly installed on the outer wall of the vertical plate, a winding roller fixedly installed on the output shaft of the winding motor, an unwinding roller and a support roller rotatably connected to the outer wall of the vertical plate, a fixed frame, a fixed shell, a laser thickness measuring device and a support frame fixedly installed on the outer wall of the vertical plate, a rotating roller rotatably connected to the inner wall of the support frame, a movable plate slidably connected to the inner wall of the fixed frame, a limit plate fixedly installed at the bottom of the movable plate, and the outer wall of the limit plate rotating. The device is equipped with a rotating column, and a threaded column is rotatably connected to the inner wall of the fixed frame. A cylinder is fixedly installed on the top of the fixed shell, and a pigment storage box is fixedly installed on the telescopic end of the cylinder. A pigment filling port is fixedly installed on the top of the pigment storage box. An angled block is fixedly installed on the inner wall of the fixed shell. A push plate is slidably connected to the inner wall of the pigment storage box. A sliding plate and a limit rod are fixedly installed on the outer wall of the push plate. A spring is provided on the inner wall of the pigment storage box. A limit groove is opened on the inner wall of the pigment storage box. An open groove is opened on the top of the push plate. A rotating wheel is rotatably connected to the inner wall of the pigment storage box.

[0006] As a preferred technical solution of this utility model: the shape of the open groove is the same as the shape of the discharge port, and the open groove is located at the bottom of the discharge port.

[0007] As a preferred technical solution of this utility model: the spring is located on the inner wall of the limiting groove, and the shape of the spring is adapted to the limiting groove.

[0008] As a preferred technical solution of this utility model: the outer wall of the sliding plate near the beveled block and the outer wall of the beveled block are both inclined surfaces, and the outer wall of the sliding plate is parallel to the outer wall of the beveled block.

[0009] As a preferred technical solution of this utility model: the threaded column passes through the movable plate, and the threaded column and the movable plate are connected by threads.

[0010] As a preferred technical solution of this utility model: the limiting plate is in contact with the inner wall of the fixing frame, and the rotating column penetrates the fixing frame and the upright plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The thickness detection device for graphite soft felt production rotates a threaded column, which in turn moves the moving plate through a threaded connection with the moving plate. The moving plate then moves a limiting plate, which in turn moves the rotating column. At this time, the limiting plate is in contact with one side of the graphite soft felt, thus limiting one side of the graphite soft felt. Meanwhile, the other side of the graphite soft felt is in contact with the inner wall of the fixed frame, thus limiting both sides of the graphite soft felt. This prevents the graphite soft felt from tilting and detaching from the measuring point of the laser thickness measuring device during movement.

[0013] 2. The thickness detection device for graphite felt production, when the thickness of the graphite felt exceeds a set threshold, sends a signal to the cylinder to start the support roller. This causes the support roller to move the pigment storage box downwards, which in turn moves the sliding plate downwards. The sliding plate then moves into the pigment storage box through contact with the inclined block, causing it to move further inwards. This causes the sliding plate to move the push plate and the open slot to contact the discharge port. At this time, the pigment inside the pigment storage box moves outwards through the open slot and the discharge port, causing the rotating wheel to mark the thicker or thinner parts of the graphite felt through contact with the graphite felt.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A thickness detection device for graphite felt production includes a base 1, a vertical plate 2 fixedly mounted on the top of the base 1, a winding motor 3 fixedly mounted on the outer wall of the vertical plate 2, a winding roller 4 fixedly mounted on the output shaft of the winding motor 3, an unwinding roller 5 and a support roller 6 rotatably connected to the outer wall of the vertical plate 2, a fixed frame 7, a fixed shell 8, a laser thickness measuring device 9 and a support frame 10 fixedly mounted on the outer wall of the vertical plate 2, a rotating roller 11 rotatably connected to the inner wall of the support frame 10, a movable plate 12 slidably connected to the inner wall of the fixed frame 7, a limit plate 14 fixedly mounted on the bottom of the movable plate 12, a rotating column 15 rotatably connected to the outer wall of the limit plate 14, and the fixed frame 7... The inner wall of the fixed shell 8 is rotatably connected to a threaded column 13. A cylinder 16 is fixedly installed on the top of the fixed shell 8. A pigment storage box 17 is fixedly installed on the telescopic end of the cylinder 16. A pigment filling port 18 is fixedly installed on the top of the pigment storage box 17. An angled block 19 is fixedly installed on the inner wall of the fixed shell 8. A push plate 21 is slidably connected to the inner wall of the pigment storage box 17. A sliding plate 20 and a limit rod 25 are fixedly installed on the outer wall of the push plate 21. A spring 26 is provided on the inner wall of the pigment storage box 17. A limit groove 27 is opened on the inner wall of the pigment storage box 17. An open groove 23 is opened on the top of the push plate 21. A rotating wheel 22 is rotatably connected to the inner wall of the pigment storage box 17.

[0022] In the above structure, the rotating wheel 22 is located at the bottom of the push plate 21. When the pigment inside the pigment storage box 17 flows down through the outlet 24 and the open groove 23, it will flow to the outer wall of the rotating wheel 22. The pigment is coated on the outside of the graphite soft felt by the contact between the rotating wheel 22 and the graphite soft felt.

[0023] In a preferred embodiment, the shape of the open groove 23 is the same as that of the outlet 24, and the open groove 23 is located at the bottom of the outlet 24.

[0024] In the above structure, the movement of the push plate 21 causes the open groove 23 to move. When the open groove 23 moves to coincide with the discharge port 24, the discharge port 24 and the open groove 23 are in an open state, so that the pigment at the top of the discharge port 24 can reach the outside of the rotating wheel 22 through the inner wall of the discharge port 24 and the open groove 23.

[0025] In a preferred embodiment, the spring 26 is located on the inner wall of the limiting groove 27, and the shape of the spring 26 is adapted to the limiting groove 27.

[0026] In the above structure, the spring 26 is limited by the limiting groove 27 so that the spring 26 will not tilt when it moves. At the same time, the spring 26 limits the push plate 21 so that the push plate 21 will not tilt when it moves.

[0027] In a preferred embodiment, the outer wall of the sliding plate 20 near the beveled block 19 and the outer wall of the beveled block 19 are both inclined surfaces, and the outer wall of the sliding plate 20 is parallel to the outer wall of the beveled block 19.

[0028] In the above structure, the downward movement of the pigment storage box 17 causes the sliding plate 20 to move downward. The sliding plate 20 is pressed by the angled block 19 as it moves downward, causing the sliding plate 20 to move into the pigment storage box 17. This causes the sliding plate 20 to move the push plate 21, which in turn causes the open slot 23 to move.

[0029] In a preferred embodiment, the threaded post 13 passes through the movable plate 12, and the threaded post 13 and the movable plate 12 are threadedly connected.

[0030] In the above structure, by rotating the threaded column 13, the threaded column 13 drives the moving plate 12 to move through the threaded connection with the moving plate 12, which in turn drives the limiting plate 14 to move, which in turn drives the rotating column 15 to move.

[0031] In a preferred embodiment, the limiting plate 14 is in contact with the inner wall of the fixing frame 7, and the rotating column 15 passes through the fixing frame 7 and the upright plate 2.

[0032] In the above structure, the limiting plate 14 is attached to the inner wall of the fixed frame 7, so that the limiting plate 14 is limited by the inner wall of the fixed frame 7 when it moves, thus preventing the limiting plate 14 from shifting when it moves. At the same time, the rotating column 15 passes through the upright plate 2 and the fixed frame 7, so that the limiting plate 14 drives the rotating column 15 to slide on the inner wall of the fixed frame 7 and the upright plate 2 when it moves.

[0033] Working principle: When using the equipment, the graphite soft felt roll is placed outside the unwinding roller 5. One end of the graphite soft felt passes through the fixing frame 7, the fixing shell 8, and the laser thickness measuring device 9 and is fixed to the outside of the winding roller 4. At this time, by rotating the rotating threaded column 13, the threaded column 13 drives the moving plate 12 to move through the threaded connection with the moving plate 12. The moving plate 12 drives the limiting plate 14 to move, which in turn drives the rotating column 15 to move. This causes the limiting plate 14 to fit against one side of the graphite soft felt, thus limiting one side of the graphite soft felt. At this time, the other side of the graphite soft felt fits against the inner wall of the fixing frame 7, thus limiting the other side of the graphite soft felt. This prevents the graphite soft felt from disengaging from the measuring point of the laser thickness measuring device 9 during movement. Then, the winding motor 3 is started, causing the winding roller 4 to rotate. The winding roller 4 winds up the graphite felt, and the thickness of the graphite felt is measured by the laser thickness measuring device 9. When the thickness exceeds the preset value, the cylinder 16 is activated, causing the pigment storage box 17 to move downward. The pigment storage box 17 then moves the sliding plate 20 downward. Through the contact between the sliding plate 20 and the bevel block 19, the sliding plate 20 is squeezed by the bevel block 19 as it moves downward, causing the sliding plate 20 to move into the pigment storage box 17. This causes the sliding plate 20 to move the push plate 21, which in turn moves the open groove 23, causing the open groove 23 to coincide with the discharge port 24. At this time, the pigment flows to the outside of the rotating wheel 22 through the open groove 23 and the discharge port 24. The contact between the rotating wheel 22 and the graphite felt marks the position where the graphite felt exceeds the preset thickness.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
