Detailed Description of the Preferred Embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-5, the present utility model provides a technical solution: a finished roll material device for conductive foam production, including: a push roll support 1, the upper end inside of the push roll support 1 is rotatably connected with a push roll 2, the upper front surface of the push roll support 1 is connected with a first motor 3, the front side output end of the first motor 3 passes through the push roll support 1 and is connected to the lower push roll 2, a tension roll support 4 is arranged on the left side of the push roll support 1, the upper inner side of the tension roll support 4 is rotatably connected with a tension roll 5, the upper front surface of the tension roll support 4 is connected with a second motor 6, the front side output end of the second motor 6 passes through the tension roll support 4 and is connected to the rear end of the tension roll 5, a rotating shaft 7 is rotatably connected inside the tension roll support 4 and below the tension roll 5, a third motor 8 is connected to the upper front surface of the tension roll support 4 and below the second motor 6, the front side output end of the third motor 8 passes through the tension roll support 4 and is connected to the rear end of the rotating shaft 7, the outer side of the lower end of the rotating shaft 7 is connected with a fitting support 9, the lower end of the fitting support 9 is arc-shaped, an auxiliary roll 10 is rotatably connected inside the lower end of the fitting support 9, a cutting knife electric slide rail 11 is connected to the upper end of the fitting support 9 and above the auxiliary roll 10, a cutting knife slider 12 is inserted and connected inside the cutting knife electric slide rail 11, a cutting knife 13 is connected to the left side of the cutting knife slider 12, a turntable seat 14 is arranged on the left side of the tension roll support 4, a turntable 15 is rotatably connected inside the upper end of the turntable seat 14, paper tube core sleeve columns 16 are rotatably connected to the left and right sides of the front surface of the turntable seat 14, a sleeve column motor is connected inside the turntable 15 and behind the paper tube core sleeve columns 16, and the paper tube core sleeve columns 16 are fixedly connected to the output end of the sleeve column motor.
[0022] During use, the conductive foam to be wound is pulled between the two push rolls 2, then passed through the upper part of the tension roll 5, the two paper tube core sleeve columns 16 are sleeved with paper tube cores, and the conductive foam is wound on the outside of the paper tube core. After completing the preliminary preparation work, start the first motor 3, the second motor 6 and the sleeve column motor. The two push rolls 2 will push the conductive foam forward, and the paper tube core sleeve columns 16 will rotate to wrap the conductive foam on the outside. When the set thickness is reached, start the turntable 15 to rotate 180°. At this time, the positions of the two paper tube core sleeve columns 16 are interchanged. Start the third motor 8 to drive the rotating shaft 7 to rotate. At the same time, the fitting support 9 will also rotate together. The auxiliary roll 10 at the end of the fitting support 9 will lift the conductive foam upward to prevent the fitting support 9 from scratching the conductive foam. Then start the cutting knife electric slide rail 11, and the cutting knife slider 12 will slide forward inside the cutting knife electric slide rail 11. The cutting knife 13 on the cutting knife slider 12 will cut the conductive foam. The arc at the front end of the fitting support 9 will also fit the cut conductive foam on the paper tube core outside the paper tube core sleeve column 16. Then the third motor 8 rotates in reverse to reset the fitting support 9, remove the conductive foam on the other paper tube core sleeve column 16, sleeve on a new paper tube core, and wait for the next winding to be completed.
[0023] As Figures 1-5 shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, a single-wheel tension sensor is provided at the connection between the inside of the rear end of the tension roller 5 and the tension roller bracket 4.
[0024] Analyzing the above structure, after setting the tension range inside the tension sensor, when the tension is higher than the set tension, the rotation speeds of the first motor 3, the second motor 6, and the sleeve column motor will be reduced to prevent excessive tension from tearing the conductive foam.
[0025] As Figures 1-5 shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, the height of the tension roller 5 is higher than the heights of the two paper tube core sleeve columns 16.
[0026] Analyzing the above structure, the height of the tension roller 5 is higher than the heights of the two paper tube core sleeve columns 16 to provide a certain tension during winding to prevent the conductive film from not adhering to the outside of the paper tube core.
[0027] As Figures 1-5 shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, an air shaft 21 is fixedly connected to the outside of the two paper tube core sleeve columns 16.
[0028] Analyzing the above structure, after sleeving the paper tube core on the paper tube core sleeve column 16 and starting the air shaft 21, the paper tube core will be fixed, thereby fixing paper tube cores with different diameters.
[0029] As Figures 1-5 shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, a rubber anti-slip layer is provided on the outer surfaces of the two pushing rollers 2.
[0030] Analyzing the above structure, the rubber anti-slip layer on the outer surface of the pushing roller 2 can provide a certain frictional force during winding.
[0031] As Figures 1-5 shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, a chute 22 is opened in the right side of the inside of the lower end of the turntable base 14. The inside of the front and rear sides of the chute 22 is connected with a slider 23. The upper surface of the slider 23 is connected with a guide roller 24. The upper end of the guide roller 24 is higher than the upper end of the paper tube core sleeve column 16.
[0032] Analyzing the above structure, insert the slider 23 into the inside of the chute 22, adjust the two guide rollers 24 to the front and rear sides of the winding position, and then fix the slider 23 with bolts. During winding, the guide roller 24 will play a guiding role for the front and rear sides of the conductive foam to prevent the position of the conductive foam from shifting.
[0033] As Figures 1-5 shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, electric telescopic rods 25 are connected to the front and rear sides of the upper end inside the pushing roller bracket 1. The lower telescopic end of the electric telescopic rod 25 is connected to a bearing, and the bearing is sleeved outside the upper pushing roller 2.
[0034] Analyzing the above structure, it can be seen that when winding conductive foam with different thicknesses, the electric telescopic rod 25 is started to lift or lower the upper pushing roller 2, so as to adjust the distance between the two pushing rollers 2, thereby winding conductive foam with different thicknesses.
