Description

Technical Field

[0002] Flexible graphite paper is a flexible material made of natural graphite after high temperature baking and compression. It has excellent thermal conductivity, mechanical strength and oxidation resistance, and is widely used in various fields. Graphite paper needs to be calendered in the manufacturing process, and is generally processed by a calender.

The utility model moves the handle to the left, and the handle drives the disc to move, so that the disc drives the fixed rod to move, and the clamping rod is squeezed by the clamping groove to move inward, and then the fixed rod can be taken out, and then the graphite paper sleeve is placed on the rotating rod, and then the user resets the fixed rod so that the fixed rod is re-stuck inside the fixed groove, and the graphite paper sleeve can be protected by the disc, and the graphite paper sleeve can be limited, so that the calendering device achieves excellent stability; this device solves the problem that the graphite paper roll is easily offset and tilted during the rotation and unwinding of the graphite paper roll.

DETAILED DESCRIPTION

[0048] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0049] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0050] Example 1

[0051] like Figure 1 As shown, the present invention provides a calendering device for producing antioxidant flexible graphite paper, comprising:

[0052] The calendering unit comprises two calendering rollers 1 arranged one above the other, the calendering rollers 1 are rotatably connected to the frame and connected to the output end of the driving motor;

[0053] A deviation correction unit 2, which is disposed at the front end of the calendering unit and symmetrically arranged on both sides of the graphite paper 3;

[0054] The image acquisition device 4 is located on the upper part of the frame and is used to acquire image information of the upper surface of the graphite paper 3. The controller controls the operation of the correction unit 2 according to the acquired image information.

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] A calendering device for producing antioxidant flexible graphite paper. When in use, a driving motor drives two calendering rollers 1 to rotate, providing power for the calendering process; a gap of preset size is provided between the two calendering rollers 1, and graphite paper 3 passes through the gap between the two calendering rollers 1 to be calendered into a preset thickness; a correction unit 2 is provided at the front end of the calendering roller 1, and image information of the upper surface of the graphite paper 3 is collected by an image acquisition device 4 and transmitted to a controller, the controller processes the image to identify the edge of the graphite paper 3, and compares it with the preset edge of the graphite paper 3, and calculates the offset of the edge of the graphite paper 3; when the offset exceeds the preset value, the controller issues an instruction to the correction unit, controls the action of the correction unit, and causes it to push the edge of the graphite paper 3 to move, and readjusts the graphite paper 3 to the preset position.

[0057] Through the above structural design, a calendering device for producing antioxidant flexible graphite paper is provided, and an image acquisition device 4 is used to monitor the position status of the graphite paper 3 in real time. When the graphite paper 3 deviates along the width direction, the correction unit 2 is automatically started to adjust the position of the graphite paper 3, thereby effectively realizing the function of automatically correcting the deviation of the graphite paper 3 before calendering, ensuring the accurate position of the graphite paper 3 during the calendering process, thereby ensuring that the force of the graphite paper 3 is balanced during the calendering process, and at the same time, it can reduce the deflection of the graphite paper 3 in the winding process after calendering, thereby improving the quality of the finished product and production efficiency of the graphite paper 3.

[0058] Example 2

[0059] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1, the calendering device for producing antioxidant flexible graphite paper further includes: a guide unit, which is arranged at the front end of the calendering unit, and the guide unit includes two upper guide rollers 5 arranged at the upper part and two lower guide rollers 6 arranged at the lower part, the two upper guide rollers 5 are located between the two lower guide rollers 6, and the graphite paper 3 wraps around the guide rollers and passes between the two calendering rollers 1; the deviation correction unit is located between the two upper guide rollers 5.

[0060] The working principle and beneficial effects of the above technical solution are:

[0061] By setting a guide unit, the traveling direction of the graphite paper 3 is guided during the calendering process; the graphite paper 3 sequentially surrounds the first lower guide roller, the first upper guide roller, the correction unit, the second upper guide roller and the second lower guide roller, and then passes between the two calendering rollers 1; a height difference is set between the two upper guide rollers 5 and the two lower guide rollers 6, so that the graphite paper 3 can be tightly pressed against the upper guide rollers 5 and form a plane between the two upper guide rollers 5, so as to avoid the graphite paper 3 bulging upward or downward when the correction unit 2 adjusts the position of the graphite paper 3.

[0062] Example 3

[0063] like Figure 1 As shown, based on the above-mentioned embodiment 2, the calendering units are provided in multiple groups, and the multiple groups of calendering units are evenly arranged between the two upper guide rollers 5 .

[0064] The working principle and beneficial effects of the above technical solution are:

[0065] The calendering units are arranged in multiple groups, and the multiple groups of calendering units can perform multi-level position adjustment on the graphite paper 3 to prevent the problem that the graphite paper 3 is locally stressed and cannot return to its position quickly when a single group of calendering units is used, thereby further improving the deviation correction effect of the graphite paper 3.

[0066] Example 4

[0067] like Figure 2 , 3As shown, based on the above embodiment 1, the correction unit 2 includes:

[0068] A support rod 11, the support rod 11 is connected to the frame, a driving chamber 12 is provided at the end of the support rod 11, an electric telescopic rod 13 is provided in the driving chamber 12, one end of the electric telescopic rod 13 is hinged to the support rod 11, and the other end extends out of the support rod 11;

[0069] The deflection correcting plate 14 has its bottom end hinged to the end of the support rod 11 , the extended end of the electric telescopic rod 13 is hinged to the deflection correcting plate 14 , and an avoidance groove for the rotation of the deflection correcting plate 14 is provided on the support rod 11 , and the deflection correcting plate 14 abuts against the edge of the graphite paper 3 .

[0070] The working principle and beneficial effects of the above technical solution are:

[0071] The controller identifies the edge of the graphite paper 3 based on the collected image information, and calculates the offset on the left and right sides of the graphite paper 3, and uses this as a basis to control the action of the correction unit 2. When the correction unit 2 is not in action, the edge of the graphite paper 3 abuts against the correction plate 14; when the correction unit 2 is in action, the controller starts the electric telescopic rod 13 of the correction unit 2 on one side to extend, and the electric telescopic rod 13 pushes the correction plate 14 to rotate, so that the inclination angle of the correction plate 14 increases, and the correction plate 14 squeezes the edge of the graphite paper 3 on this side inward, pushing the graphite paper 3 back to the preset position, thereby achieving the correction of the graphite paper 3; after the correction is completed, the controller starts the electric telescopic rod 13 of the correction unit 2 to retract, and the correction plate 14 rotates in the opposite direction to reset.

[0072] Example 5

[0073] like Figure 2 , 3 As shown, based on the above-mentioned embodiment 4, the correcting plate 14 is inclined and the top end is spread outward, the width of the correcting plate 14 gradually increases from bottom to top, and the edge of the graphite paper 3 abuts against the inclined surface of the correcting plate 14.

[0074] The working principle and beneficial effects of the above technical solution are:

[0075] The width of the deflection correcting plate 14 increases gradually from bottom to top. When the deflection correcting plate 14 rotates, the upper part of the deflection correcting plate 14 applies greater pressure to the edge of the graphite paper 3, causing the graphite paper 3 to tend to move downward, thereby preventing the edge of the graphite paper 3 from warping upward during the deflection correcting adjustment process.

[0076] Example 6

[0077] like Figure 4-7 As shown, based on the above-mentioned embodiment 5, the calendering device for producing the antioxidant flexible graphite paper further includes a blowing unit, and the blowing unit includes:

[0078] Gas distribution pipeline 21, the gas distribution pipeline 21 is connected to the frame, and the gas distribution pipeline 21 is connected to the gas source equipment;

[0079] A flow regulating valve 22, which is arranged on the gas distribution pipeline 21 and is used to adjust the flow rate of the spraying gas flow;

[0080] The blowing frame 23 is set as a U-shaped frame, the middle part of the blowing frame 23 is connected to the gas distribution pipeline 21, the two arms of the blowing frame 23 are respectively connected to the support rods 11 of the two correction units 2, and the air inlet end of the blowing frame 23 is connected to the gas distribution pipeline 21 through a pipeline.

[0081] The blowing unit includes an upper blowing part, and the upper blowing part includes:

[0082] The nozzle adjustment shaft 24 is rotatably connected between the two arms of the blowing frame 23, one end of the nozzle adjustment shaft 24 is connected to the output end of the motor, the motor is installed on the blowing frame 23, and the motor is connected to the controller, and the nozzle adjustment shaft 24 is connected to an ear plate 35;

[0083] A nozzle sleeve 25, the nozzle sleeve 25 is connected to the center of the nozzle adjustment shaft 24, and a spring 36 is connected between the nozzle sleeve 25 and the spray frame 23;

[0084] A nozzle support rod 26, the nozzle support rod 26 is installed in the nozzle sleeve 25;

[0085] The nozzle 27 has one end connected to the nozzle support rod 26 , the blowing port of the nozzle 27 extends toward the upper surface of the graphite paper 3 , and the air inlet end of the nozzle 27 is connected to the air distribution pipeline 21 through a pipeline.

[0086] The working principle and beneficial effects of the above technical solution are:

[0087] When the blowing unit is in use, the gas source device delivers the airflow to the blowing rack 23 through the air distribution pipeline 21, and adjusts the flow rate of the blowing airflow through the flow regulating valve 22. When the upper blowing part of the blowing unit is in use, the air distribution pipeline 21 delivers the airflow to the nozzle sleeve 27 through the pipeline, and the nozzle 27 is installed in the nozzle sleeve 25 through the nozzle support rod 26. The airflow in the nozzle 27 is blown to the upper surface of the graphite paper 3 through the blowing port to blow off the dust on the upper surface of the graphite paper 3; at the same time, the motor on the blowing rack 23 is started, and the nozzle adjustment shaft 24 is driven to rotate, and the nozzle adjustment shaft 24 drives the nozzle sleeve 25 to rotate, and the nozzle sleeve 25 drives the nozzle 27 to rotate, and the angle between the nozzle 27 and the graphite paper 3 is adjusted, and then the blowing angle of the airflow on the graphite paper 3 is adjusted; through the cyclic action of the motor, the blowing angle of the airflow on the graphite paper 3 changes cyclically. When the nozzle sleeve 25 rotates, the pulling spring 36 is deformed to store energy, which helps to keep the position of the nozzle sleeve 25 stable under the action of the elastic force.

[0088] Through the above structural design, the deviation correction unit 2 and the blowing unit are integrated into one, so that the nozzle 27 can face the upper surface of the graphite paper 3 to blow off the dust on the upper part of the graphite paper 3; the direction of the blowing airflow in the nozzle 27 changes, and the upper surface of the graphite paper 3 is fully sprayed, thereby reducing the blind spots for cleaning, improving the cleaning effect of the dust on the graphite paper 3, reducing the impurities mixed with oil during the calendering process of the graphite paper 4, and improving the quality of the finished product of the graphite paper 3.

[0089] Example 7

[0090] like Figure 4-7 As shown, based on the above-mentioned embodiment 6, the blowing unit includes a lower blowing part, and the lower blowing part includes:

[0091] The air inlet channel 28 is arranged on the support rod 11 and the arm of the blowing frame 23. The air inlet end of the air inlet channel 28 is connected to the air distribution pipeline 21 through a pipeline. The bottom end of the air inlet channel 28 is provided with an air outlet 29, and the air outlet 29 passes through the bottom end of the support rod 11;

[0092] The guide groove 31 is arranged at the bottom end of the support rod 11 , the upper part of the guide groove 31 is connected with the air outlet 29 , the lower part of the guide groove 31 is open, and the air outlet end of the guide groove 31 faces the lower surface of the graphite paper 3 .

[0093] The working principle and beneficial effects of the above technical solution are:

[0094] During the calendering process, dust adhered to the lower surface of the graphite paper 3 will also affect the quality of the finished graphite paper 3. By setting the lower blowing part, when in use, the airflow in the air distribution pipeline 21 enters the air inlet channel 28, and then flows out through the air outlet 29 of the air inlet channel 28. After the airflow enters the guide groove 31, it is sprayed toward the lower surface of the graphite paper 3 through the air outlet end of the guide groove 31, thereby achieving dust cleaning on the lower surface of the graphite paper 3, thereby improving the quality of the finished product of the graphite paper 3 after calendering.

[0095] Example 8

[0096] like Figure 4-7 As shown, based on the above embodiment 7, the blowing unit further includes:

[0097] An opening and closing frame 32, one end of the opening and closing frame 32 is hinged on the support arm of the blowing frame 23, and the other end extends to below the deviation correcting plate 14, and the opening and closing frame 32 surrounds the support arm of the blowing frame 23, and a lug 33 is provided at the bottom end of the opening and closing frame 32;

[0098] A connecting rod 34 has one end hinged to a lug 33 at the bottom end of the opening and closing frame 32 and the other end hinged to an upper lug 35 of the nozzle adjusting shaft 24 .

[0099] The opening and closing frame 32 comprises:

[0100] A guide groove 37, the guide groove 37 is horizontally arranged on the side plate of the opening and closing frame 32;

[0101] A guide plate 38, the guide plate 38 is slidably connected in the guide groove 38, and the guide plate 38 is horizontally arranged at the lower part of the guide groove 31 to form the bottom surface of the guide groove 31;

[0102] The rotating rod 39 has one end hinged to the bottom end of the opening and closing frame 32 and the other end hinged to the guide plate 38 . The bottom end of the opening and closing frame 32 is provided with a groove for accommodating the rotating rod 39 .

[0103] The working principle and beneficial effects of the above technical solution are:

[0104] When the spray unit is in use, the motor drives the nozzle adjustment shaft 24 to rotate counterclockwise, and the ear plate 35 of the nozzle adjustment shaft 24 drives the connecting rod 34 to move away from the graphite paper 3, and then the connecting rod 34 drives the opening and closing frame 32 to rotate, and the downward opening angle relative to the spray frame 23 increases; the spray frame 23 drives the bottom end of the rotating rod 39 to rotate, so that the top end of the rotating rod 39 pulls the guide plate 38 to slide outward along the guide groove 37, and the guide plate 38 is horizontally arranged at the bottom of the guide groove 31 to form its bottom surface, thereby increasing the bottom surface of the guide groove 31, and the airflow sprayed through the guide groove 31 moves forward at the spray point on the graphite paper 3. Therefore, in the process of adjusting the spray angle of the airflow in the upper spray part, the airflow spray position in the lower spray part can be adjusted.

[0105] Through the above structural design, the synchronous adjustment of the airflow blowing positions of the upper blowing part and the lower blowing part is effectively realized, so that the blowing unit can fully blow the upper and lower surfaces of the graphite paper 3, effectively improving the dust cleaning effect of the graphite paper 3. In addition, due to the different blowing positions and blowing strengths of the airflows on the upper and lower surfaces of the graphite paper 3, the upper and lower surfaces of the graphite paper 3 are subjected to uneven forces, and then a small amplitude shake occurs, which is helpful to shake off the dust during the blowing process, and the tension of the graphite paper 3 during the transmission process is adjusted by shaking, thereby improving the force uniformity of the graphite paper 3.
