Description

Technical Field

[0001] This invention relates to the field of graphene electrothermal film technology, and more specifically to a cutting device for graphene electrothermal films. Background Technology

[0002] Graphene electric heating film is a semi-transparent polyester film that can generate heat when electricity is applied. It is made by hot-pressing conductive graphene ink and metal current-carrying strips between insulating polyester films. When working, the electric heating film heats up and sends heat into the space in the form of far-infrared rays, so that people and objects are warmed first. Its energy saving and heating effect are much better than traditional heating methods.

[0003] Currently, the graphene heating film is typically laid manually on the ground. This requires multiple people to work together during the cutting process, and manual cutting is prone to tilting, which can cause leakage and waste. Therefore, we have proposed a cutting device for graphene heating film. Summary of the Invention

A push rod is located at the end of the two curved rods that are close to each other, which facilitates the movement of the vehicle board by pulling the push rod. The graphene electrothermal film is rolled up inside the curved roll frame, which increases the convenience of laying the graphene electrothermal film. The curved roll frame is rotatably connected to the end of the fixed plate that is close to each other through a bearing. A semi-circular block is fixedly connected to the inner wall of the curved roll frame. The end of the curved roll frame is fixedly connected to the rotating rod.

The arc-shaped spring plate is fixedly connected to the top of the inclined plate. There are four arc-shaped spring plates, which are arranged in pairs. The two pairs of arc-shaped spring plates are arranged on the top surface of the end of the inclined plate.

The end of the rubber rod is fixedly connected to the arc-shaped spring plate.

[0013] The rubber rod is located at the lower end of the toothed blade.

[0014] Furthermore, the rubber rod is located at the lower end of the round rod, and the toothed blade and the toothed end of the toothed blade are mutually misaligned and adapted.

There are two ring blocks located at the ends of the cylindrical rod. The moving rod slides inside the sliding hole of the sliding hole block via the sliding block at its end. The sliding hole block limits the movement of the moving rod. The support frame is set below the push rod via a bottom rod. The support frame is located near the center of the moving rod. The top rod and the vertical block are hinged via a straight rod. The inclined rod is fixedly connected to the surface of the ring block. The rubber roller is rotatably connected to the lower end of the inclined rod via a rotating shaft.

[0019] The end of the inclined rod away from the annular block is inclined downward, and the sliding block is slidably connected to the inner wall of the sliding hole block.

[0020] Furthermore, the adjustment mechanism includes a base rod, a support frame, an adjustment block, a movable plate, a round hole block, a threaded rod, and a screw hole block. There are two round hole blocks, which are fixedly connected to the surfaces of the push rod and the moving rod, respectively. The screw hole block is hinged to the bottom of the round hole block through the movable plate. The threaded rod is threaded to the inner wall of the screw hole block. The support frame is fixedly connected to the bottom of the push rod through the base rod.

[0021] The adjusting block is fixedly connected to the lower surface of the threaded rod, and the threaded rod is rotatably connected to the top of the support frame through a bearing.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention fixes the end of the graphene heating film to the surface of a curved roll frame. A semi-circular block is installed inside the frame to support and isolate the graphene heating film, preventing it from adhering to the frame. An electric push rod drives a motor upwards, causing a locking lever at the end of a rotating rod to move into a slot. As the motor rotates, the locking lever pushes the rotating rod to rotate, allowing the curved roll frame to bend and collect the graphene heating film. The locking lever separates from the inner wall of the slot as the electric push rod moves downwards. This reduces the pulling force required when the curved roll frame rotates, facilitating the laying of the graphene heating film by pulling the vehicle platform.

[0024] When the graphene electrothermal film needs to be cut, the present invention pushes the slide to slide on the top of the sliding frame through the synchronous rod. The connecting rod pushes the pull rod to move through the movement of the slide. Since the end of the pull rod is rotatably connected to the surface of the cylindrical rod, the pull rod pushes the cylindrical rod to rotate when it moves. The toothed cutter moves to the center of the inclined plate through the rotation of the cylindrical rod and contacts the surface of the graphene electrothermal film. The graphene electrothermal film is cut by the toothed cutter. The horizontal setting of the toothed cutter and the cylindrical rod increases the flatness of the graphene electrothermal film during cutting.

[0025] In this invention, when laying the graphene heating film, the graphene heating film slides on the surface of the rubber rod, which protects the graphene heating film. When the toothed cutter cuts the graphene heating film through the round rod, the toothed cutter will squeeze the rubber rod downward. Because the toothed cutter and the toothed blade are staggered, the toothed cutter can engage with the toothed blade to cut the graphene heating film. Through the cooperation of the toothed cutter and the toothed blade, the sharpness of cutting the graphene heating film is improved.

[0026] When the round rod of this invention rotates, the pressure rod moves into the interior of the semi-circular frame through the elastic pressure plate. The pressure rod clamps the graphene heating film inside the semi-circular frame. Because the first semi-circular pad and the second semi-circular pad are staggered, the second semi-circular pad is moved by the pressure rod and inserted into the end of the first semi-circular pad that is close to each other, thus clamping and fixing the graphene heating film. This avoids insufficient tension of the graphene heating film when the toothed cutter cuts the graphene heating film, which would otherwise reduce the efficiency of cutting the graphene heating film.

[0027] When the tension of the graphene heating film needs to be increased during installation, the adjusting block rotates the threaded rod at the top of the support frame. As the threaded block moves downward through the rotation of the threaded rod, it pulls the moving rod towards one end of the push rod via the connection between the movable plate and the circular hole block. The vertical block pulls the top rod towards one end of the moving rod via the straight rod. The circular ring block moves downward through the pressure of the inclined rod via the top rod. The rubber roller presses the graphene heating film downward through the downward movement of the inclined rod, increasing the tension of the graphene heating film during installation. At the same time, when the threaded block moves upward, the inclined rod moves upward through the circular ring block, reducing the tension of the graphene heating film during installation.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0038] Example 1

[0039] Please see Figures 1-6 This invention relates to a cutting device for graphene electrothermal films, comprising:

[0040] The vehicle platform 1 has casters 2 at its bottom and a bent rod 7 fixedly connected to the top left side of the vehicle platform 1. A push rod 8 is fixedly connected to the end of the bent rod 7.

[0041] A support plate 5 is fixedly connected to the front end of the car plate 1. An electric push rod 4 is fixedly connected to the top of the support plate 5. A motor 3 is fixedly connected to the top of the electric push rod 4. A rotating rod 16 is fixedly connected to the output end of the motor 3. A locking rod 15 is fixedly connected to the end of the rotating rod 16. A rotating rod 13 is provided at the end of the rotating rod 16 away from the motor 3. A slot 14 is opened on the surface of the rotating rod 13. A fixing plate 6 is fixedly connected to the top of the car plate 1. A curved frame 10 is rotatably connected to the end of the fixing plate 6 that is close to each other through a bearing. A semi-circular block 11 is fixedly connected to the inner wall of the curved frame 10. The end of the curved frame 10 is fixedly connected to the rotating rod 13. In this invention, the end of the graphene electrothermal film is fixed to the surface of the curved frame 10. The interior of the frame 10 is provided with a semi-circular block 11, which supports and isolates the graphene heating film to prevent it from adsorbing inside the frame 10. The electric push rod 4 pushes the motor 3 to move upward, and the locking rod 15 at the end of the rotating rod 16 moves into the slot 14. When the rotating rod 16 is rotated by the motor 3, the locking rod 15 pushes the rotating rod 13 to rotate. The frame 10 rolls up and stores the graphene heating film by rotating the rotating rod 13. The locking rod 15 separates from the inner wall of the slot 14 by the downward movement of the electric push rod 4. When laying the graphene heating film, the pulling force required when the frame 10 is rotated is reduced, making it easier to lay the graphene heating film by pulling the car plate 1.

[0042] A cutting mechanism 12 is provided on the top right side of the car plate 1, and a tensioning mechanism 9 is provided above the car plate 1.

[0043] The clamping rod 15 is adapted to the inner wall of the clamping slot 14, the fixing plate 6 is located on the top left side of the plate 1, and four semi-circular blocks 11 are provided inside the curved frame 10.

[0044] The cutting mechanism 12 includes a round rod 20, a vertical plate 21, an auxiliary mechanism 22, a base plate 23, a toothed blade 24, an inclined plate 25, a pull rod 26, a cylindrical rod 27, a connecting rod 28, a sliding frame 29, a synchronizing rod 30, a spring 31, a slide 32, and a limiting rod 33. The vertical plate 21 is fixedly connected to the top of the car plate 1 via the base plate 23. The cylindrical rod 27 is rotatably connected to the vertical plate 21 via a bearing. The surfaces of the round rod 20 and the cylindrical rod 27 are fixedly connected. The toothed blade 24 is fixedly connected to the lower surface of the cylindrical rod 27. The pull rod 26 is fixedly connected to the end of the cylindrical rod 27. The end of the inclined plate 25 is fixedly connected to the surface of the vertical plate 21. The auxiliary mechanism 22 is provided on the top of the inclined plate 25. The sliding frame 29 is fixedly connected to the top of the bent rod 7. The inner wall of the slide 32 is fixedly connected to the end of the limiting rod 33. The connection is as follows: the limiting rod 33 is fixedly connected to the inner wall of the sliding frame 29 via the spring 31, and the end of the synchronizing rod 30 is fixedly connected to the surface of the slide 32. When the graphene electrothermal film needs to be cut, the synchronizing rod 30 pushes the slide 32 to slide on the top of the sliding frame 29. The connecting rod 28 pushes the pull rod 26 to move through the movement of the slide 32. Since the end of the pull rod 26 is rotatably connected to the surface of the cylindrical rod 27, the pull rod 26 pushes the cylindrical rod 20 to rotate through the cylindrical rod 27 when it moves. The toothed cutter 24 moves towards the center of the inclined plate 25 through the rotation of the cylindrical rod 20 and contacts the surface of the graphene electrothermal film. The toothed cutter 24 cuts the graphene electrothermal film. The horizontal setting of the toothed cutter 24 and the cylindrical rod 20 increases the flatness of the graphene electrothermal film during cutting.

[0045] The tie rod 26 is hinged to the top of the carriage 32 via the connecting rod 28, and the tie rod 26 is located at one end of the upright plate 21 that is far apart from each other.

[0046] The end of the cylindrical rod 27 passes through the vertical plate 21 and extends to the outer end of the vertical plate 21. The toothed cutter 24 is set above the inclined plate 25. The slide 32 is slidably connected to the surface of the sliding hole frame 29. The limiting rod 33 is set inside the sliding hole of the sliding hole frame 29.

[0047] The auxiliary mechanism 22 includes a groove 40, an arc-shaped spring plate 41, a rubber rod 42, and a toothed blade 43. The groove 40 is located on the top of the inclined plate 25. The toothed blade 43 is fixedly connected to the bottom of the inner wall of the groove 40. The arc-shaped spring plate 41 is fixedly connected to the top of the inclined plate 25. The end of the rubber rod 42 is fixedly connected to the arc-shaped spring plate 41. When the graphene electrothermal film is laid, the graphene electrothermal film slides on the surface of the rubber rod 42, which protects the graphene electrothermal film. When the toothed blade 24 cuts the graphene electrothermal film through the round rod 20, the toothed blade 24 will squeeze the rubber rod 42 downward. Because the toothed blade 24 and the toothed blade 43 are staggered, the toothed blade 24 can mesh with the toothed blade 43 to cut the graphene electrothermal film. Through the cooperation of the toothed blade 24 and the toothed blade 43, the sharpness of cutting the graphene electrothermal film is improved.

[0048] The rubber rod 42 is located at the lower end of the toothed blade 43.

[0049] The rubber rod 42 is located at the lower end of the round rod 20, and the toothed blade 43 and the toothed blade 24 are mutually misaligned and adapted.

[0050] A clamping mechanism 44 is provided at one end of the round rod 20 near the inclined plate 25, and the left side of the inclined plate 25 is inclined downward.

[0051] The clamping mechanism 44 includes a semi-circular frame 50, a first semi-circular pad 51, a second semi-circular pad 52, a pressure rod 53, and an elastic pressure plate 54. The pressure rod 53 is fixedly connected to the surface of the round rod 20 via the elastic pressure plate 54. The second semi-circular pad 52 is fixedly connected to the lower surface of the pressure rod 53. The semi-circular frame 50 is fixedly connected to the top of the inclined plate 25. The first semi-circular pad 51 is fixedly connected to the bottom of the inner wall of the semi-circular frame 50. When the round rod 20 rotates, the pressure rod 53 moves via the elastic pressure plate 54. The pressure rod 53 clamps the graphene heating film inside the semi-circular frame 50. Since the semi-circular pad 1 51 and the semi-circular pad 2 52 are staggered, the semi-circular pad 2 52 is moved by the pressure rod 53 and inserted into the end of the semi-circular pad 1 51 that is close to each other, thus clamping and fixing the graphene heating film. This avoids insufficient tension of the graphene heating film when the toothed cutter 24 cuts the graphene heating film, which would reduce the efficiency of cutting the graphene heating film.

[0052] The semicircular frame 50 is located at the top and bottom of the inclined plate 25, and the semicircular pad 1 51 and the semicircular pad 2 52 are staggered.

[0053] Example 2

[0054] Distinguishing features from Example 1;

[0055] like Figure 7-8As shown: The tensioning mechanism 9 includes a circular ring block 60, a top rod 61, a diagonal rod 62, a rubber roller 63, a straight rod 64, a sliding hole block 65, a sliding block 66, a vertical block 67, a moving rod 68, and an adjusting mechanism 69. The circular ring block 60 is rotatably connected to the surface of the cylindrical rod 27 via a bearing. The top rod 61 is fixedly connected to the top of the circular ring block 60. The sliding hole block 65 is fixedly connected to the surface of the bent rod 7. The end of the moving rod 68 is fixedly connected to the sliding block 66. The lower end of the moving rod 68 is provided with the adjusting mechanism 69. The lower surface of the moving rod 68 is fixedly connected to the vertical block 67. The top rod 61 and the vertical block 67 are hinged via the straight rod 64. The diagonal rod 62 is fixedly connected to the surface of the circular ring block 60. The rubber roller 63 is rotatably connected to the lower end of the diagonal rod 62 via a rotating shaft. When it is necessary to increase the tension of the graphene heating film during installation, the threaded rod 75 is rotated at the top of the support frame 71 by adjusting the threaded rod 75. When the threaded rod 75 rotates and moves downward, the threaded rod 76 will pull the moving rod 68 to one end of the push rod 8 through the connection between the movable plate 73 and the round hole block 74. The vertical block 67 pulls the top rod 61 to one end of the moving rod 68 through the straight rod 64. The ring block 60 presses the inclined rod 62 downward through the top rod 61. The rubber roller 63 presses the graphene heating film through the downward movement of the inclined rod 62, increasing the tension of the graphene heating film during installation. At the same time, when the threaded rod 76 moves upward, the inclined rod 62 will move upward through the ring block 60, reducing the tension of the graphene heating film during installation.

[0056] The end of the diagonal rod 62 away from the annular block 60 is inclined downwards, and the sliding block 66 is slidably connected to the inner wall of the sliding hole block 65.

[0057] The adjustment mechanism 69 includes a base rod 70, a support frame 71, an adjustment block 72, a movable plate 73, a round hole block 74, a threaded rod 75, and a screw hole block 76. There are two round hole blocks 74, which are fixedly connected to the surfaces of the push rod 8 and the moving rod 68, respectively. The screw hole block 76 is hinged to the bottom of the round hole block 74 through the movable plate 73. The threaded rod 75 is threaded to the inner wall of the screw hole block 76. The support frame 71 is fixedly connected to the bottom of the push rod 8 through the base rod 70.

[0058] The adjusting block 72 is fixedly connected to the lower surface of the threaded rod 75, and the threaded rod 75 is rotatably connected to the top of the support frame 71 through a bearing.

[0059] A specific application of this embodiment is as follows: the end of the graphene electrothermal film is fixed to the surface of the roll-up frame 10. A semi-circular block 11 is provided inside the roll-up frame 10 to support and isolate the graphene electrothermal film, preventing it from adsorbing inside the roll-up frame 10. The electric push rod 4 pushes the motor 3 to move upward, and the locking rod 15 at the end of the rotating rod 16 moves into the slot 14. When the rotating rod 16 is rotated by the motor 3, the locking rod 15 pushes the rotating rod 13 to rotate. The roll-up frame 10 rolls up and stores the graphene electrothermal film by rotating the rotating rod 13. The locking rod 15 separates from the inner wall of the slot 14 by the downward movement of the electric push rod 4. This reduces the pulling force required when the roll-up frame 10 rotates during the laying of the graphene electrothermal film, making it easier to pull. When laying the graphene heating film on the car plate 1, and when cutting the graphene heating film is required, the sliding carriage 32 is pushed by the synchronous rod 30 to slide on the top of the sliding hole frame 29. The connecting rod 28 pushes the pull rod 26 to move through the movement of the sliding carriage 32. Since the end of the pull rod 26 is rotatably connected to the surface of the cylindrical rod 27, the pull rod 26 pushes the cylindrical rod 20 to rotate through the cylindrical rod 27 when it moves. The toothed cutter 24 moves towards the center of the inclined plate 25 through the rotation of the cylindrical rod 20 and contacts the surface of the graphene heating film. The toothed cutter 24 cuts the graphene heating film. The horizontal setting of the toothed cutter 24 and the cylindrical rod 20 increases the flatness of the graphene heating film during cutting. When laying the graphene heating film, the graphene heating film slides on the surface of the rubber rod 42. The graphene heating film is protected by the rubber rod 42. When the toothed cutter 24 cuts the graphene heating film through the round rod 20, the toothed cutter 24 will squeeze the rubber rod 42 downward. Because the toothed cutter 24 and the toothed blade 43 are misaligned, the toothed cutter 24 can mesh with the toothed blade 43 to cut the graphene heating film. The cooperation between the toothed cutter 24 and the toothed blade 43 improves the sharpness of cutting the graphene heating film. When the round rod 20 rotates, the pressure rod 53 moves into the interior of the semi-circular frame 50 through the elastic pressure plate 54. The pressure rod 53 clamps the graphene heating film inside the semi-circular frame 50. Because the semi-circular pad 1 51 and the semi-circular pad 2 52 are misaligned, the semi-circular pad 2 52 is moved by the pressure rod 53 and locked into the semi-circular pad 1 51, and they are pressed together. At the near end, the graphene heating film is clamped and fixed to prevent insufficient tension in the graphene heating film when the toothed cutter 24 cuts it, thus reducing the efficiency of cutting the graphene heating film. When it is necessary to increase the tension during the laying of the graphene heating film, the threaded rod 75 is rotated at the top of the support frame 71 by adjusting the block 72. When the screw hole block 76 moves downward through the rotation of the threaded rod 75, the screw hole block 76 will pull the moving rod 68 towards one end of the push rod 8 through the connection between the movable plate 73 and the round hole block 74. The vertical block 67 pulls the top rod 61 towards one end of the moving rod 68 through the straight rod 64. The ring block 60 is pressed downward by the inclined rod 62 through the top rod 61. The rubber roller 63 is pressed by the downward movement of the inclined rod 62.To increase the tension of the graphene heating film during installation, and simultaneously, as the screw hole block 76 moves upward, the diagonal rod 62 moves upward through the ring block 60, thus reducing the tension of the graphene heating film during installation.
