[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0036] Reference Figures 1-8 and Figure 17, an automatic laminating machine for aluminum core blades, including a hydraulic rod 5 and an electromagnetic induction heating plate 9, the bottom of the hydraulic rod 5 is fixed with a connecting plate 6, the bottom of the connecting plate 6 is fixed with a slider 7, the bottom of the electromagnetic induction heating plate 9 is fixed with a pressing plate 10, the upper surface of the electromagnetic induction heating plate 9 is fixed with two U-shaped grooves 13 on both sides, the slider 7 slides between the two grooves 13, the top of the electromagnetic induction heating plate 9 is fixed with a support spring 8, the top of the support spring 8 is fixed to the bottom of the slider 7, and is horizontal on both sides of the connecting plate 6 A sliding rod 42 is fixedly connected, and a sliding connecting piece 43 is slidably fitted on the sliding rod 42. A connecting block 44 is fixedly connected to the bottom end of the sliding connecting piece 43, and a cutting knife 47 is fixedly connected to the connecting block 44. A guide groove 45 is provided through the connecting block 44, and a guide rod 46 is fixedly connected to the outer wall of the groove 13. The guide rod 46 slides in the guide groove 45. A notch 22 is provided on the side wall of the groove 13, and a U-shaped scraper 14 slides in the notch 22. A compression spring 15 is provided in the groove 13 to apply elastic force to the scraper 14.
[0037] When coating the aluminum core blade 4, the aluminum core blade 4 is first transported by the conveyor belt 1 to transport the aluminum core blade 4 to the bottom of the pressure plate 10, and then the film paper 2 is pulled by the traction equipment to move the film paper 2 between the aluminum core blade 4 and the pressure plate 10.
[0038] Next, the electromagnetic induction heating plate 9 preheats the pressing plate 10. After the temperature of the pressing plate 10 rises to the required temperature, the hydraulic rod 5 is started. The hydraulic rod 5 applies a downward force to the connecting plate 6 to drive the pressing plate 10 to move downward. After the pressing plate 10 moves downward, it will squeeze the film paper 2 and make the film paper 2 fit on the aluminum core blade 4. Under the high temperature of the pressing plate 10, the hot melt adhesive on the aluminum core blade 4 melts and bonds the film paper 2.
[0039] After the film paper 2 is bonded to the aluminum core blade 4, the hydraulic rod 5 continues to drive the connecting plate 6 to move downward. The slider 7 on the bottom of the connecting plate 6 will compress the supporting spring 8 and drive the sliding rod 42 to move downward. The downward movement of the sliding rod 42 will drive the sliding connector 43 to move downward synchronously. During the downward movement of the sliding connector 43, the connecting block 44 will be driven downward.
[0040] During the downward movement of the connecting block 44, the guide rod 46 and the guide groove 45 cooperate to guide the connecting block 44 so that the cutting knife 47 on the connecting block 44 approaches the side wall of the pressure plate 10 during the downward movement. When the cutting knife 47 moves to the lowest point, it will be attached to the side wall of the pressure plate 10 and cut the film paper 2 to remove the excess film paper.
[0041] After the cutting is completed, the hydraulic rod 5 drives the connecting plate 6 to move upward, and the connecting plate 6 drives the slider 7 and the slide rod 42 to move upward during the movement of the slide rod 42. During the movement of the slide rod 42, the cutting knife 47 is driven upward through the sliding connection 43 and the connecting block 44 to reset.
[0042] During the upward movement of the cutting blade 47 , the scraper 14 is pressed against the cutting blade 47 by the elastic force of the compression spring 15 , thereby cleaning the glue adhered to the surface of the cutting blade 47 .
[0043] like Figure 4-12 As shown, to improve the quality of cleaning glue from the cutting blade 47, the present invention has a first driven pulley 16 rotatably mounted on one side of the top of the scraper 14, and a first driving pulley 23 rotatably mounted on the other side of the top of the scraper 14. A first sandpaper belt 18 is mounted in conjunction with the first driven pulley 16 and the first driving pulley 23 to polish and clean the cutting blade 47. A second driven pulley 17 is rotatably mounted on one side of the bottom of the scraper 14, and a second driving pulley 24 is rotatably mounted on the other side of the bottom of the scraper 14. A second sandpaper belt 19 is mounted in conjunction with the second driven pulley 17 and the second driving pulley 24 to polish and clean the cutting blade 47. The bottom of the first driving pulley 23 is coaxially fixed with a first driven end face gear 28, the top of the second driving pulley 24 is coaxially fixed with a second driven end face gear 29, the top of the electromagnetic induction heating plate 9 is fixed with a motor 11, in order to prevent the motor 11 from interfering with the sliding process of the slider 7, the slider 7 is provided with a receiving groove 12 for accommodating the motor 11, the output shaft of the motor 11 is fixed with an inner spline tube 25, and a spline shaft 26 is slidably fitted in the inner spline tube 25, the spline shaft 26 is rotatably connected to the side wall of the scraper 14, and the end of the spline shaft 26 is fixed with a driving gear 27, and both the first driven end face gear 28 and the second driven end face gear 29 are matched with the driving gear 27.
[0044] When the motor 11 is powered on, it drives the inner spline tube 25 to rotate. The rotation of the inner spline tube 25 drives the spline shaft 26 to rotate. The rotation of the spline shaft 26 drives the driving gear 27 to rotate. The driving gear 27 drives the first driven end face gear 28 and the second driven end face gear 29 to rotate. The first driven end face gear 28 and the second driven end face gear 29 rotate in opposite directions.
[0045] The rotation of the first driven end face gear 28 drives the first driving pulley 23 to rotate, and the rotation of the first driving pulley 23 drives the first sandpaper belt 18 to work;
[0046] The rotation of the second driven end gear 29 drives the second driving pulley 24 to rotate, and the rotation of the second driving pulley 24 drives the second sandpaper belt 19 to work;
[0047] Under the elastic force exerted by the compression spring 15 on the scraper 14, the first sandpaper belt 18 and the second sandpaper belt 19 will abut against the surface of the cutting blade 47 to polish and clean it. Because the first driven end gear 28 and the second driven end gear 29 rotate in opposite directions, the first sandpaper belt 18 and the second sandpaper belt 19 rotate in opposite directions during operation. During the polishing and cleaning process, the first sandpaper belt 18 and the second sandpaper belt 19 polish and clean the cutting blade 47 in different horizontal directions, thereby improving the cleaning quality.
[0048] like Figures 11-16 As shown, columns 40 are vertically fixed on both sides of the scraper 14, a sleeve 41 is slidably fitted on the column 40, a cleaning roller 32 is rotatably mounted on the sleeve 41, a reciprocating screw 30 is coaxially fixed to the bottom of the first driven end face gear 28, a connecting rod 31 is threadedly fitted on the reciprocating screw 30, and the cleaning roller 32 is rotatably connected to the connecting rod 31. The bottom of the first driven pulley 16 is fixedly connected to the first driving end face gear 20, the top of the second driven pulley 17 is fixedly connected to the second driving end face gear 21, the scraper 14 is vertically fixedly connected to a support plate 33, and a rotating shaft 34 is rotatably installed on the support plate 33. One end of the rotating shaft 34 is fixedly connected to the driven gear 35, and the other end is fixedly connected to the first synchronous pulley 39. The first driving end face gear 20 and the second driving end face gear 21 are matched with the driven gear 35. One end of the cleaning roller 32 is fixedly connected to the second synchronous pulley 38. A synchronous belt 37 is installed on the first synchronous pulley 39 and the second synchronous pulley 38. A tensioning pulley 36 is provided on the support plate 33 to ensure that the synchronous belt 37 is maintained at an appropriate tension.
[0049] During the rotation of the first driving pulley 23 and the second driving pulley 24, the two sandpaper belts will drive the first driven pulley 16 and the second driven pulley 17 to rotate. During the rotation of the first driven pulley 16 and the second driven pulley 17, the first driving end face gear 20 and the second driving end face gear 21 will be driven to rotate. Since the first driving end face gear 20 and the second driving end face gear 21 are both engaged with the driven gear 35, the driven gear 35 will be driven to rotate. During the rotation of the driven gear 35, the first synchronous pulley 39 is driven to rotate through the rotating shaft 34. The first synchronous pulley 39 drives the second synchronous pulley 38 to rotate through the synchronous belt 37. The rotation of the second synchronous pulley 38 drives the cleaning roller 32 to rotate. Under the elastic force of the compression spring 15, the cleaning roller 32 is pressed against the surface of the cutting knife 47 to clean the surface of the cutting knife 47 during the rotation of the cleaning roller 32.
[0050] During the rotation of the first active pulley 23, the reciprocating screw 30 fixedly connected thereto will also rotate synchronously. The rotation of the reciprocating screw 30 will drive the connecting rod 31 to perform reciprocating linear motion in the vertical direction, thereby driving the cleaning roller 32 to perform a small reciprocating linear motion in the vertical direction, so that the cleaning roller 32 can grind and clean the cutting knife 47 in the vertical direction.
[0051] Working principle:
[0052] When coating the aluminum core blade 4, the aluminum core blade 4 is first transported by the conveyor belt 1 to transport the aluminum core blade 4 to the bottom of the pressure plate 10, and then the film paper 2 is pulled by the traction equipment to move the film paper 2 between the aluminum core blade 4 and the pressure plate 10.
[0053] Next, the electromagnetic induction heating plate 9 preheats the pressing plate 10. After the temperature of the pressing plate 10 rises to the required temperature, the hydraulic rod 5 is started. The hydraulic rod 5 applies a downward force to the connecting plate 6 to drive the pressing plate 10 to move downward. After the pressing plate 10 moves downward, it will squeeze the film paper 2 and make the film paper 2 fit on the aluminum core blade 4. Under the high temperature of the pressing plate 10, the hot melt adhesive on the aluminum core blade 4 melts and bonds the film paper 2.
[0054] After the film paper 2 is bonded to the aluminum core blade 4, the hydraulic rod 5 continues to drive the connecting plate 6 to move downward. The slider 7 on the bottom of the connecting plate 6 will compress the supporting spring 8 and drive the sliding rod 42 to move downward. The downward movement of the sliding rod 42 will drive the sliding connector 43 to move downward synchronously. During the downward movement of the sliding connector 43, the connecting block 44 will be driven downward.
[0055] During the downward movement of the connecting block 44, the guide rod 46 and the guide groove 45 cooperate to guide the connecting block 44 so that the cutting knife 47 on the connecting block 44 approaches the side wall of the pressure plate 10 during the downward movement. When the cutting knife 47 moves to the lowest point, it will be attached to the side wall of the pressure plate 10 and cut the film paper 2 to remove the excess film paper.
[0056] After the cutting is completed, the hydraulic rod 5 drives the connecting plate 6 to move upward, and the connecting plate 6 drives the slider 7 and the slide rod 42 to move upward during the movement of the slide rod 42. During the movement of the slide rod 42, the cutting knife 47 is driven upward through the sliding connection 43 and the connecting block 44 to reset.
[0057] During the upward movement of the cutting blade 47 , the scraper 14 is pressed against the cutting blade 47 by the elastic force of the compression spring 15 , thereby cleaning the glue adhered to the surface of the cutting blade 47 .
[0058] After the cutting blade 47 is reset, the hydraulic rod 5 will continue to apply an upward force to the connecting plate 6 to reset the pressing plate 10.
[0059] After the pressing plate 10 is reset, the conveyor belt 1 transports the aluminum core blade 4 to the bottom of the blade 3, and the blade 3 performs a secondary trimming of the excess film paper 2 at both ends of the aluminum core blade 4.
[0060] The above cleaning process is as follows:
[0061] When the motor 11 is powered on, it drives the inner spline tube 25 to rotate. The rotation of the inner spline tube 25 drives the spline shaft 26 to rotate. The rotation of the spline shaft 26 drives the driving gear 27 to rotate. The driving gear 27 drives the first driven end face gear 28 and the second driven end face gear 29 to rotate. The first driven end face gear 28 and the second driven end face gear 29 rotate in opposite directions.
[0062] The rotation of the first driven end face gear 28 drives the first driving pulley 23 to rotate, and the rotation of the first driving pulley 23 drives the first sandpaper belt 18 to work;
[0063] The rotation of the second driven end gear 29 drives the second driving pulley 24 to rotate, and the rotation of the second driving pulley 24 drives the second sandpaper belt 19 to work;
[0064] Under the elastic force exerted by the compression spring 15 on the scraper 14, the first sandpaper belt 18 and the second sandpaper belt 19 will abut against the surface of the cutting blade 47 to polish and clean it. Because the first driven end gear 28 and the second driven end gear 29 rotate in opposite directions, the first sandpaper belt 18 and the second sandpaper belt 19 rotate in opposite directions during operation. During the polishing and cleaning process, the first sandpaper belt 18 and the second sandpaper belt 19 polish and clean the cutting blade 47 in different horizontal directions, thereby improving the cleaning quality.
[0065] During the rotation of the first driving pulley 23 and the second driving pulley 24, the two sandpaper belts will drive the first driven pulley 16 and the second driven pulley 17 to rotate. During the rotation of the first driven pulley 16 and the second driven pulley 17, the first driving end face gear 20 and the second driving end face gear 21 will be driven to rotate. Since the first driving end face gear 20 and the second driving end face gear 21 are both engaged with the driven gear 35, the driven gear 35 will be driven to rotate. During the rotation of the driven gear 35, the first synchronous pulley 39 is driven to rotate through the rotating shaft 34. The first synchronous pulley 39 drives the second synchronous pulley 38 to rotate through the synchronous belt 37. The rotation of the second synchronous pulley 38 drives the cleaning roller 32 to rotate. Under the elastic force of the compression spring 15, the cleaning roller 32 is pressed against the surface of the cutting knife 47 to clean the surface of the cutting knife 47 during the rotation of the cleaning roller 32.
[0066] During the rotation of the first active pulley 23, the reciprocating screw 30 fixedly connected thereto will also rotate synchronously. The rotation of the reciprocating screw 30 will drive the connecting rod 31 to perform reciprocating linear motion in the vertical direction, thereby driving the cleaning roller 32 to perform a small reciprocating linear motion in the vertical direction, so that the cleaning roller 32 can grind and clean the cutting knife 47 in the vertical direction.
[0067] Compared with the existing technology, the automatic laminating machine for aluminum core blades provided by the present invention can automatically clean the glue adhered to the cutting knife 47 during the continuous production process, which can not only prevent the glue from corroding the cutting knife 47, but also prevent the dust and film paper debris attached to the glue from polluting the product, thereby improving the production quality.
[0068] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
