Description

Technical Field

[0002] Thermally conductive carbon film is a material with excellent thermal conductivity and multiple properties. It has broad application prospects in many fields. With the continuous development of science and technology, the performance and application fields of thermally conductive carbon film will continue to expand and improve.

[0003] During the production and processing of thermal conductive carbon film, operators generally use cutting devices to cut the thermal conductive carbon film, so as to divide the large roll of thermal conductive carbon film into small rolls for subsequent processing. Because some thermal conductive carbon films are flexible, when the cutting knife on the cutting device contacts the thermal conductive carbon film, it may cause the thermal conductive carbon film to be dragged, causing the position of the thermal conductive carbon film to shift, resulting in uneven cutting surface, affecting the quality of the cut product and the subsequent processing of the thermal conductive carbon film.

[0004] Therefore, the utility model provides a cutting device for producing a thermally conductive carbon film to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a cutting device for producing thermal conductive carbon film, comprising a table body, the top surface of the table body is connected to a stand, the top surface of the stand is connected to an electric push rod, the movable end of the electric push rod passes through the stand and is connected to the top surface of the mounting plate, the two side surfaces of the mounting plate are connected with sliders, one end of the slider extends into a slide groove opened on the inner surface of the stand, the bottom surface of the mounting plate is connected with a cutting knife, the top surface of the table body is provided with a cutting groove, the top surface of the mounting plate at both ends is penetrated and connected with a slide rod, the bottom surface of the slide rod is connected with a threaded column, one end of the threaded column extends into the inside of the threaded groove, the threaded groove is opened on the top surface of the pressing plate, one end of the slide rod is penetrated and connected with a spring, the top surface of the pressing plate is provided with a through groove, and the bottom surface of the pressing plate is connected with a rubber block, the top surfaces of the two ends of the table body are also provided with limiting mechanisms, and a thermal conductive carbon film is placed on the top surface of the table body.

A movable groove is opened on the top surface at both ends of the table body, and bearings are connected to the surfaces at both ends of the movable groove. A bidirectional screw is connected between the two bearings, one end of the bidirectional screw extends into the table body and is connected to the output end of the motor, and movable blocks are connected through both ends of the bidirectional screw.

[0008] In order to achieve normal operation of the electric push rod and the motor and improve the stability of the mounting plate when moving, as a preferred cutting device for producing thermal conductive carbon films in the utility model, the electric push rod and the motor are electrically connected to an external power supply through a control switch, and the slider is slidably connected to the stand through a slide groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model uses the mutual cooperation among the slide rod, the threaded column, the pressure plate, the spring, the through groove and the rubber block. When the cutting knife cuts the thermal conductive carbon film downward, the rubber block at the bottom of the pressure plate will first press and restrict the cut part of the thermal conductive carbon film to be fixed on the desktop, thereby avoiding the situation that the thermal conductive carbon film is shifted in position during the cutting process and ensuring the neatness of the cut surface of the thermal conductive carbon film.

[0014] The utility model can limit the conveyed thermal conductive carbon film by setting a limiting mechanism and adjusting the distance between the two moving blocks, thereby ensuring that the thermal conductive carbon film is always in the center position of the table body, and avoiding the situation where the thermal conductive carbon film is offset and the cutting knife cannot cut completely.

[0023] Preferably: the limiting mechanism includes: a moving groove 16, a bearing 17, a bidirectional screw 18, a motor 19 and a moving block 20, a moving groove 16 is opened on the top surface at both ends of the table body 1, and the surfaces at both ends of the moving groove 16 are connected with bearings 17, a bidirectional screw 18 is connected between the two bearings 17, one end of the bidirectional screw 18 extends into the table body 1 and is connected to the output end of the motor 19, and moving blocks 20 are connected through both ends of the bidirectional screw 18.

[0024] During specific use, the motor 19 can be started, and the output end of the motor 19 can drive the bidirectional screw 18 to rotate in the bearing 17, so that the moving block 20 on the bidirectional screw 18 can move along the moving groove 16, thereby changing the distance between the two moving blocks 20, and moving the moving blocks 20 to the two ends of the thermal conductive carbon film 21, thereby limiting the position of the thermal conductive carbon film 21.

[0025] Preferably, the electric push rod 3 and the motor 19 are electrically connected to an external power source via a control switch, and the slider 5 is slidably connected to the stand 2 via a slide groove 6 .

[0026] During specific use, the electric push rod 3 and the motor 19 can be controlled by a switch. When the movable end of the electric push rod 3 drives the mounting plate 4 to move downward, the sliders 5 on both sides of the mounting plate 4 will also slide in the slide groove 6 to ensure the stability of the mounting plate 4 when moving.

[0027] Preferably, the position and size of the through groove 14 and the cutting groove 8 match the position and size of the cutting knife 7 .

[0028] During specific use, the cutting knife 7 will pass through the through slot 14 during the process of moving downward, so that one end of the cutting knife 7 can enter the cutting slot 8.

[0029] Preferably, the slide rod 9 is in sliding connection with the mounting plate 4 , and the threaded column 10 is in threaded connection with the pressing plate 12 via the threaded groove 11 .

[0030] During specific use, the sliding rod 9 can slide on the mounting plate 4. The sliding rod 9 slides through the mounting plate 4 so that the threaded column 10 at the bottom can be screwed into the threaded groove 11, so that the sliding rod 9 can be connected to the pressure plate 12 through the threaded column 10. Before the sliding rod 9 is connected to the pressure plate 12, the spring 13 can be placed on the top of the pressure plate 12, so that the sliding rod 9 can pass through the spring 13 and then be connected to the pressure plate 12.

[0031] Preferably, the output end of the motor 19 is fixedly connected to the bidirectional screw 18 , the moving block 20 is slidably connected to the table body 1 through the moving groove 16 , and the moving block 20 and the bidirectional screw 18 are threadedly connected.

[0032] During specific use, the output end of the motor 19 can drive the bidirectional screw 18 to rotate, so that the moving block 20 on the bidirectional screw 18 can move along the moving groove 16 .

[0033] Working principle: When using the cutting device for the production of thermal conductive carbon film, place the large roll of thermal conductive carbon film 21 on the unwinding device at one end of the table body 1, and then pull one end of the large roll of thermal conductive carbon film 21 through the table body 1, so that one end of the thermal conductive carbon film 21 is connected to the winding device on the other side of the table body 1, then the motor 19 can be started, and the output end of the motor 19 drives the bidirectional screw 18 to rotate in the bearing 17, so that the moving block 20 on the bidirectional screw 18 will move along the moving groove 16, thereby changing the distance between the two moving blocks 20, so that the moving block 20 moves to the thermal conductive carbon The two ends of the film 21 are located so as to limit the position of the thermally conductive carbon film 21. In this way, when the winding device is winding the thermally conductive carbon film 21, the thermally conductive carbon film 21 can only move between the two moving blocks 20, ensuring that the thermally conductive carbon film 21 is always in the center of the table body 1 during the transportation process, avoiding the position of the thermally conductive carbon film 21 from being offset, resulting in part of the thermally conductive carbon film 21 not being under the cutting knife 7, making it impossible for the cutting knife 7 to completely cut the thermally conductive carbon film 21. When the winding device is finished winding, it is necessary to cut the thermally conductive carbon film 21, and then the electric pusher is started. Rod 3, let the movable end of the electric push rod 3 drive the mounting plate 4 to move downward, and the slider 5 will also slide in the slide groove 6 when the mounting plate 4 moves, ensuring the stability of the mounting plate 4 when it moves. In this way, when the mounting plate 4 moves downward, the rubber block 15 on the pressure plate 12 connected to the bottom of the slide rod 9 will first contact the thermal conductive carbon film 21. When the mounting plate 4 continues to slide downward, the slide rod 9 will slide on the mounting plate 4, and the mounting plate 4 will also squeeze the spring 13, so that the spring 13 can fix the position of the pressure plate 12 on the table body 1 through elasticity, so that the pressure plate 1 The rubber block 15 at the bottom of the pressing plate 12 will press and restrict the cutting portion of the thermal conductive carbon film 21 on the table body 1. In this way, when the mounting plate 4 continues to drive the cutting knife 7 to move downward, one end of the cutting knife 7 will pass through the through groove 14 and enter the cutting groove 8, thereby completing the cutting operation of the thermal conductive carbon film 21. In this way, because the thermal conductive carbon film 21 is pressed on the table body 1 by the rubber block 15 at the bottom of the pressing plate 12, the position of the thermal conductive carbon film 21 will not be offset during the cutting process, thereby ensuring that the cutting surface of the thermal conductive carbon film 21 is neat and will not affect the subsequent processing of the thermal conductive carbon film 21.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
