Description

Technical Field

[0001] The present invention relates to the technical field of aluminum foil paper processing, and specifically to a folding mechanism and method for flanging and folding aluminum foil paper. Background Art

[0002] Aluminum foil paper refers to the paper formed by laminating and bonding aluminum foil lining paper and aluminum foil. Existing aluminum foil paper is usually used to prepare aluminum foil paper cups and insulation sleeves. In order to quickly prepare aluminum foil paper into insulation sleeves, it is necessary to perform a flanging treatment on the aluminum foil paper. When flanging the aluminum foil paper, it is necessary to perform an indentation treatment in advance and then fold the aluminum foil paper. A trimming machine for facilitating the flanging and folding of aluminum foil paper disclosed in the patent with the publication number CN114042588B records that the aluminum foil paper conveyed by a conveyor belt is trimmed, indented, and coated with glue through a trimming mechanism, an indentation mechanism, and a glue coating mechanism provided on a frame. Since the trimming mechanism, the indentation mechanism, and the glue coating mechanism are arranged in sequence along the conveying direction of the conveyor belt, the aluminum foil paper can be indented and coated with glue synchronously after trimming. The indentation mechanism ensures that the trimmed aluminum foil paper has an indentation for facilitating flanging, thereby facilitating the flanging quality of the trimmed aluminum foil paper, improving the quality of the aluminum foil paper. The glue coating treatment can evenly coat the surface of the aluminum foil paper with glue, ensuring the fixing quality after the aluminum foil paper is flanged.

[0003] However, when performing an indentation treatment on the aluminum foil paper, it is impossible to finely adjust the indentation position and indentation amplitude, and the flexibility is poor, resulting in large limitations of the product.

[0004] Based on this, a folding mechanism and method for flanging and folding aluminum foil paper are now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, as Figures 1-4 shown, a folding mechanism for flanging and folding aluminum foil paper includes a conveyor belt 11 for conveying the aluminum foil cardboard 31 to be processed. Transmission frames 27 are arranged on both sides of the conveyor belt 11. Support legs 29 for support are arranged at the lower ends of the transmission frames 27. A transmission motor 28 for driving the conveyor belt 11 to rotate is arranged outside the support legs 29. Under the action of the transmission motor 28, the conveyor belt 11 can convey the aluminum foil cardboard 31. Above the conveyor belt 11, there is an indentation component for indentating the aluminum foil cardboard 31 on the surface of the conveyor belt 11 for later folding. Downstream of the indentation component, there is a guiding component for guiding the flanging of the aluminum foil cardboard 31. Above the conveyor belt 11 where the guiding component is located, there is a compaction component for tightly pressing the flanged aluminum foil cardboard 31. The two aluminum foil cardboards 31 are rolled against each other by the indentation component, thereby completing the folding of the aluminum foil paper;

[0029] The compaction component includes a pressing and positioning roller 21 arranged above the conveyor belt 11. The pressing and positioning roller 21 is in pressing contact with the surface of the conveyor belt 11. An elastic layer is arranged on the surface of the pressing and positioning roller 21, which can increase the compaction area. The pressing and positioning roller 21 can compact the folded aluminum foil cardboard 31;

[0030] The guide component includes a flanging guide plate 23 that is attached to the surface of the conveyor belt 11. The side of the flanging guide plate 23 is connected and fixed to the conveyor frame 27 or the indentation component through a positioning rod 24. The flanging guide plate 23 is inclined. A horizontally arranged fixing seat 22 is provided downstream of the flanging guide plate 23. The fixing seat 22 is connected to the conveyor frame 27. A plurality of guide roller groups 20 are provided on the fixing seat 22 for guiding the flanging of the aluminum foil cardboard 31. There are a plurality of guide roller groups 20, and the inclination angle of the guide roller group 20 gradually decreases along the conveying direction of the conveyor belt 11. The plurality of guide roller groups 20 constitute a guide rail structure for folding the aluminum foil cardboard 31 after being turned up. In this way, the aluminum foil cardboard 31 after being indented continues to be transmitted along the conveyor belt 11. The side of the aluminum foil cardboard 31 will be turned up by the flanging guide plate 23 first, and then the part of the aluminum foil cardboard 31 that is tilted up will be turned over under the guidance of the guide roller group 20 for later compaction.

[0031] The outer side of the guide roller group 20 is rotatably provided with a jacket, and the rotation setting of the jacket makes the guide roller group 20 turn the aluminum foil paper more smoothly;

[0032] The indentation component includes a horizontal cross plate 17 horizontally arranged above the conveyor belt 11, a horizontal sleeve 16 is slidably arranged on the horizontal cross plate 17, a lifting slide bar 14 is arranged on the side of the horizontal sleeve 16, and a creasing disk group 30 for creasing the aluminum foil paperboard 31 on the surface of the conveyor belt 11 is arranged at the lower end of the lifting slide bar 14, the lifting slide bar 14 is slidably arranged on the guide sleeve outside the horizontal sleeve 16, and a reset plate is arranged at the upper end of the lifting slide bar 14, and the reset plate is connected to the upper end of the horizontal sleeve 16 by a compression spring 15, so that it has a certain buffering effect during the indentation process, which is a protection for the conveyor belt 11, the horizontal cross plate 17 is connected to a lifting adjustment member for driving it to move up and down, and the height of the horizontal cross plate 17 is driven by the lifting adjustment member to adjust the height, thereby adjusting the pressure of the indentation disk group 30 on the aluminum foil paper, and the horizontal sleeve 16 is connected to a transverse fine-tuning member for driving it to move laterally, and the transverse fine-tuning member can generate a driving force for the horizontal sleeve 16, thereby adjusting the position of the indentation;

[0033] In order to ensure that the position of the aluminum foil paperboard 31 meets the requirements, the conveyor belt 11 is also provided with a feeding component for providing the aluminum foil paperboard 31. The feeding component is located in the middle of the left end of the conveyor belt 11, which provides a basis for the accuracy of the indentation.

[0034] The lateral fine-tuning member includes a transmission block 19 arranged outside the horizontal sliding sleeve 16. A regulating screw 18 is fitted in the screw hole on the transmission block 19. One end of the regulating screw 18 is rotatably connected to a fixed block outside the horizontal cross plate 17, and the other end of the regulating screw 18 is connected to a regulating motor 13 for driving its rotation. Under the action of the regulating motor 13, the regulating screw 18 and the transmission block 19 rotate relative to each other. Under the action of the thread, the horizontal sliding sleeve 16 can move horizontally on the horizontal cross plate 17, thereby adjusting the position of the indentation to meet the processing requirements of different specifications;

[0035] The lifting and adjusting member includes a lifting seat 12 arranged at the end of the horizontal cross plate 17. The lifting seat 12 is slidably arranged on the vertical frame 26. The lower end of the vertical frame 26 is fixedly connected to the outside of the transmission frame 27. The vertical frame 26 is an L-shaped plate. A lifting push rod 25 is arranged on the vertical frame 26. The output end of the lifting push rod 25 is fixedly connected to the horizontal cross plate 17. By generating a driving force on the horizontal cross plate 17 through the lifting push rod 25, the horizontal cross plate 17 can slide up and down along the vertical frame 26, thereby completing the adjustment of the compaction height;

[0036] Both the horizontal cross plate 17 and the vertical frame 26 are provided with scale bars to provide a reference for later adjustment;

[0037] The indentation disc group 30 includes an indentation roller. A raised ring is arranged at the middle position of the indentation roller. In this way, the raised ring can be used to indent the aluminum foil cardboard 31 horizontally, and the indentation roller itself flattens the indentation position, ensuring the indentation effect;

[0038] In order to facilitate the indentation of aluminum foil papers with different thicknesses, the indentation disc group 30 includes an installation disc shell 38. A rotating shaft 39 for easy installation is arranged at the center position of the installation disc shell 38. A plurality of sliding holes are arranged in an array on the outside of the installation disc shell 38. An indentation block 37 is slidably arranged in each sliding hole. A cover 34 is fitted at the end of the installation disc shell 38. A telescopic adjustment module for adjusting the protruding amplitude of the indentation block 37 is arranged at the end of the cover 34. By driving the sliding block 35 to extend through the telescopic adjustment module, the indentation of aluminum foil papers with different thicknesses can be satisfied;

[0039] The telescopic adjustment module includes an adjustment telescopic rod 33 arranged at the middle position of the cover 34. A fixed sleeve 32 is provided at the upper end of the adjustment telescopic rod 33. A sliding pressing block 35 is provided at the output end of the fixed sleeve 32. An adjustment pressing rod 36 is provided at the inner end of the indentation block 37. The adjustment pressing rod 36 is coaxially arranged with the adjustment telescopic rod 33. The adjustment pressing rod 36 is fixedly connected to the inner wall of the mounting disc housing 38 through a return spring 41. A guiding inclined surface 40 corresponding to the sliding pressing block 35 is provided at the end of the adjustment pressing rod 36. Under the action of the return spring 41, the indentation block 37 is retracted into the mounting disc housing 38. The fixed sleeve 32 drives the sliding pressing block 35 to slide close to the indentation block 37. Under the action of the side pressing of the sliding pressing block 35, the adjustment pressing rod 36 drives the indentation block 37 to slide outwards, thereby adjusting the extending amplitude of the indentation block 37;

[0040] A rounded structure is provided on the outer side of the indentation block 37. The setting of the rounded shape avoids damaging the aluminum foil paper during the indentation process.

[0041] The above embodiment discloses a folding mechanism for flanging and folding aluminum foil paper. Among them, in actual use, the aluminum foil paper board 31 is placed on the upper end of the conveyor belt 11 for transmission. As the aluminum foil paper board 31 moves, the indentation treatment of the aluminum foil paper board 31 is completed by the indentation disc group 30. After the indentation is completed, a plurality of guiding roller groups 20 constitute a guide rail structure for turning up the aluminum foil paper board 31 for folding. In this way, after the indented aluminum foil paper board 31 continues to be transmitted along the conveyor belt 11, the side of the aluminum foil paper board 31 will be first turned up by the flanging guide plate 23, and then the turned-up part of the aluminum foil paper board 31 will be turned over under the guidance of the guiding roller group 20 for later compaction.

[0042] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
