Description

Technical Field

[0001] This application relates to the field of packaging production technology, and in particular to paper cans based on an automated forming process for edge-flipping assembly. Background Technology

[0002] Paper cans are packaging containers made primarily of paper. They offer advantages such as being environmentally friendly, lightweight, and recyclable. The main structure of a paper can is typically manufactured using a paper rolling process. The wall thickness, height, and diameter of the paper tube can be adjusted as needed to accommodate different product packaging requirements. The top and bottom edges of the paper can are usually flanged or rolled to increase its structural strength and aesthetic appeal.

[0003] Currently, Chinese utility model patent application CN 118514383A, published on August 20, 2024, provides an automatic production device for ink packaging paper cans. The device includes a base plate, a gluing mechanism, an auxiliary mechanism, and a feeding mechanism. A U-shaped placement plate is fixedly installed on the top of the base plate. At least two sets of first limiting plates are integrally formed on the top of the U-shaped placement plate. A placement groove is opened on the top of the U-shaped placement plate, and a feeding port communicating with the inside of the placement groove is opened on one side of the base plate. The feeding mechanism is located on the U-shaped placement plate and includes a first lead screw, a movable ring, a fixed sleeve, and a pusher plate. This automatic production device for ink packaging paper cans, through the coordinated use of the U-shaped placement plate, the first limiting plate, and the feeding mechanism, can prepare multiple sets of paperboard at once to form a paperboard stack and automatically feed the paperboards one by one into the gluing process. The entire process requires no manual intervention, has a high degree of automation, saves manpower, and improves the practicality of the device.

[0004] The automatic production equipment for ink packaging paper cans in related technologies does not fully cover the flanging and assembly process of paper cans, and cannot form them in one piece, which reduces the production efficiency of paper cans. It is necessary to transfer paper cans between multiple devices, which not only increases the time and labor intensity of manual handling, but may also lead to the risk of damage or deformation during the transfer process.

[0005] Therefore, it is necessary to provide a paper can based on an automated forming process for edge-flipping assembly to solve the above problems. Utility Model Content

[0006] This application provides a paper can based on an automatic forming process for flanging assembly. In order to improve the technical problem in the related technology that the production equipment cannot form a single piece, which reduces production efficiency and causes the paper can to be transferred between multiple devices, resulting in the risk of damage during the transfer process.

[0007] This application provides a paper can based on an automatic forming process for edge-flanging assembly, including a frame, a support frame, a lifting frame, a heating mold assembly, an air-cooling assembly, and a transport assembly. The support frame is mounted on the frame, the lifting frame is mounted on the support frame, the air-cooling assembly is mounted on the frame, and the transport assembly is mounted on the frame. The heating mold assembly includes a heating block and a bending pre-compression block. The heating block is mounted on the lifting frame, and an edge-flanging forming groove is formed on the end of the heating block away from the lifting frame. The bending pre-compression block is mounted on the end of the heating block away from the lifting frame, and a bending pre-compression inclined surface is provided on the bending pre-compression block.

[0008] The technical solutions described above in this application embodiment have at least the following technical effects: During the process of the user performing edge-rolling operation on the paper can using the paper can production equipment, the transport component transports the paper can to the edge-rolling equipment, and the heating mold component is pressed down by the lifting frame to make the paper can perform edge-rolling operation. First, the bending pre-pressing block abuts against the paper can and the bending pre-pressing inclined surface pre-bends the inclined surface on the paper can. The edge-rolling forming groove performs edge-rolling and forming while performing thermoplastic operation, transferring heat to the forming angle pressure strip, which facilitates edge-rolling and improves forming efficiency. After the edge-rolling is completed, the transport component moves the paper can to the air-cooling component for air-cooling operation, which quickly reduces the temperature of the edge-rolled part, shortens the cooling time, and fixes the edge-rolled shape.

[0009] The paper can based on the automatic forming process of edge assembly provided in this application embodiment can effectively heat the rolled edge area by heating the mold assembly and the air cooling assembly, so as to soften the material and facilitate forming. It ensures that the rolled edge area is fully softened at high temperature, thereby achieving complex rolled edge shapes. By blowing air to cool down, the temperature of the rolled edge area can be quickly reduced, shortening the cooling time and thus improving production efficiency. Rapid cooling helps to fix the rolled edge shape and prevent the material from deforming during the cooling process.

[0024] Based on this, in order to improve the technical problems existing in the related technology, such as the inability of production equipment to be integrally molded, which reduces production efficiency and the risk of damage during the transfer of paper cans between multiple devices, the embodiments of this application provide the following solutions.

[0025] Please refer to the following: Figures 1 to 6 This application provides a paper can based on an automatic forming process for edge-flipping assembly. The paper can based on the automatic forming process for edge-flipping assembly includes a frame 1, a support frame 11, a lifting frame 12, a heating mold assembly 2, an air-cooling assembly 3, and a transport assembly 4. The support frame 11 is mounted on the frame 1, the lifting frame 12 is mounted on the support frame 11, the air-cooling assembly 3 is mounted on the frame 1, the transport assembly 4 is mounted on the frame 1, and the heating mold assembly 2 is mounted on the lifting frame 12.

[0026] In some embodiments, please refer to the following: Figures 5 to 6 The transport component 4 includes an inlet transport bar 41, an outlet transport bar 42, a rotating motor 43, a rotating shaft 44, and a rotating ring 46. The inlet transport bar 41 and the outlet transport bar 42 are mounted on the frame 1. The rotating motor 43 is mounted on the frame 1, and the rotating shaft 44 is mounted on the rotating motor 43. The rotating shaft 44 is coaxially driven with the output shaft of the rotating motor 43. The rotating ring 46 is mounted on the rotating shaft 44. Multiple placement slots 47 are provided on the rotating ring 46, and multiple connecting holes are provided in the placement slots 47. Clamping cylinders 48 are installed through the connecting holes. Abutment pads 49 are provided on the output shaft of the clamping cylinder 48, and multiple connecting protrusions 45 are provided on the rotating shaft 44.

[0027] With this configuration, during the edge-rolling operation of the paper can using the paper can production equipment, the inlet transport bar 41 transports the paper can to the edge-rolling equipment. The rotating motor 43 drives the rotating ring 46 to rotate via the rotating shaft 44. At the same time, a connecting protrusion 45 is provided on the rotating shaft 44 to reduce the possibility of relative sliding between the rotating shaft 44 and the rotating ring 46. A placement groove 47 is provided on the rotating ring 46 for placing the paper can. A clamping cylinder 48 is provided in the placement groove 47 on the rotating ring 46 to fix the position of the paper can being conveyed. When the edge-rolled paper can is transported to the outlet transport bar 42, the clamping cylinder 48 generates a pushing force on the paper can. The clamping cylinder 48 can not only determine and fix the position of the paper can, but also fix paper cans of different diameters, which is compatible. In this way, the import transport strip 41 automatically transports the paper can to the edge-rolling equipment, reducing manual intervention and improving the continuity and efficiency of the production process. The rotating motor 43 drives the rotating ring 46 to rotate via the rotating shaft 44, realizing the rapid edge-rolling operation of the paper can. At the same time, the clamping cylinder 48 can quickly transport the paper can to the export transport strip 42 after completing the edge-rolling, further improving production efficiency. By setting the connecting protrusion 45 on the rotating shaft 44, the possibility of relative sliding between the rotating shaft 44 and the rotating ring 46 is reduced, thereby ensuring the stability of the edge-rolling process. This design can effectively avoid the problem of uneven edge-rolling or damage to the paper can caused by sliding, improving the consistency of product quality. The clamping cylinder 48 can not only fix the position of the paper can, but also provide stable support during the edge-rolling process. Support ensures the precision and quality of the crimping. The design of the clamping cylinder 48 allows the equipment to adapt to paper cans of different diameters. This compatibility reduces equipment adjustment time caused by changing paper can specifications, improves the equipment's versatility and flexibility, and reduces production costs. The entire crimping process is automated, reducing manual operation steps. This not only reduces quality fluctuations caused by human intervention but also reduces the labor intensity of workers and improves the safety of the production environment. Through automated transportation, stable crimping effect, multi-functional clamping cylinder 48, and compatibility with paper cans of different diameters, production efficiency, product quality, and equipment versatility are significantly improved. At the same time, it reduces human intervention and labor intensity, improves equipment reliability and durability, and enhances the controllability of the production process.

[0028] In some embodiments, please refer to the following: Figures 2 to 4The heating mold assembly 2 includes a heating block 23 and a bending pre-pressing block 21. The heating block 23 is mounted on the lifting frame 12. A curling forming groove 24 is provided on the end of the heating block 23 away from the lifting frame 12. The bending pre-pressing block 21 is mounted on the end of the heating block 23 away from the lifting frame 12. A bending pre-pressing inclined surface 22 is provided on the bending pre-pressing block 21. A connecting block 25 is also provided on the end of the heating block 23 away from the lifting frame 12. An inner hook bend 26 is provided on the connecting block 25. A heat dissipation hole 27 is provided on the bending pre-pressing block 21. The air-cooling assembly 3 includes a fan bracket 31, a fan connecting bracket 32, a fan motor 33, and a cooling fan 34. The fan bracket 31 is mounted on the frame 1. The fan connecting bracket 32 ​​is mounted on the fan bracket 31. The fan motor 33 is mounted on the fan connecting bracket 32. The cooling fan 34 is mounted on the fan motor 33. The output shafts of the cooling fan 34 and the fan motor 33 are coaxially driven.

[0029] With this setup, the heating mold assembly 2 is pressed down by the lifting frame 12, causing the paper can to be rolled. First, the bending pre-pressing block 21 abuts against the paper can, and the bending pre-pressing inclined surface 22 pre-bends the inclined surface of the paper can. The paper can is rolled and formed by the rolling forming groove 24, and a thermoplastic operation is performed at the same time. The heat is transferred to the forming angle pressure strip, which facilitates the rolling and improves the forming efficiency. At the same time, the inner hook bend 26 on the connecting block 25 can press and fix the rolled part. Meanwhile, heat dissipation holes 27 are opened on the bending pre-pressing block 21 to avoid heat accumulation and damage to the internal structure of the heating mold assembly 2. After the rolling is completed, the rotating ring 46 drives the paper can to rotate to the position of the cooling fan 34, so that the fan motor 33 drives the heat dissipation fan to rotate, which dissipates the heat from the paper can, quickly reduces the temperature of the rolled part, shortens the cooling time, and fixes the rolled shape. Thus, the lifting frame 12 drives the heating mold assembly 2 to press down, quickly pressing the edge of the paper can into the edge-forming groove 24 to complete the edge-forming operation. During the edge-forming process, heat is transferred to the forming angle pressure strip, making the edge of the paper can easier to form in a thermoplastic state, improving forming efficiency. The bending pre-pressing block 21 abuts against the paper can, and the bending pre-pressing inclined surface 22 pre-bends the inclined surface on the paper can, preparing for subsequent edge-forming. The inner hook bend 26 on the connecting block 25 presses and fixes the edge-forming part, ensuring the stability of the edge structure of the paper can after edge-forming. This pressing and fixing method can effectively prevent the rolled edge from loosening or deforming during subsequent use. After the rolled edge is completed, the rotating ring 46 drives the paper can to rotate to the position of the cooling fan 34. The cooling fan 34 performs heat dissipation on the paper can, quickly reducing the temperature of the rolled edge. Rapid cooling helps to fix the rolled edge shape and prevents deformation due to excessive cooling time. The entire rolled edge process is automated, reducing manual intervention and improving production efficiency. Through precise pre-bending, forming and cooling control, the consistency and stability of the rolled edge quality are ensured.

[0030] The implementation principle of the paper can based on the automatic forming process of edge-flanging assembly in this application embodiment is as follows: During the edge-flanging operation of the paper can using the paper can production equipment, the inlet transport bar 41 transports the paper can to the edge-flanging equipment. The rotating motor 43 drives the rotating ring 46 to rotate through the rotating shaft 44. At the same time, a connecting protrusion 45 is provided on the rotating shaft 44 to reduce the possibility of relative sliding between the rotating shaft 44 and the rotating ring 46. A placement groove 47 is provided on the rotating ring 46 for placing the paper can. At the same time, a clamping cylinder 48 is provided in the placement groove 47 on the rotating ring 46 to fix the position of the paper can being conveyed. When the edge-flanged paper can is transported to the outlet transport bar 42, the clamping cylinder 48 generates a pushing force on the paper can. The clamping cylinder 48 can not only determine and fix the position of the paper can, but also fix paper cans of different diameters, which has the function of... During the edge-rolling process, the lifting frame 12 drives the heating mold assembly 2 to press down, causing the paper can to be rolled. First, the bending pre-pressing block 21 abuts against the paper can, and the bending pre-pressing inclined surface 22 pre-bends the inclined surface of the paper can. The edge-rolling forming groove 24 rolls the paper can while performing thermoplastic operation, transferring heat to the forming angle pressure strip, which facilitates edge-rolling and improves forming efficiency. At the same time, the inner hook bend 26 on the connecting block 25 can press and fix the rolled part. Meanwhile, heat dissipation holes 27 are opened on the bending pre-pressing block 21 to avoid heat accumulation and damage to the internal structure of the heating mold assembly 2. After the edge-rolling is completed, the rotating ring 46 drives the paper can to rotate to the position of the cooling fan 34, so that the fan motor 33 drives the heat dissipation fan to rotate, which dissipates heat from the paper can, quickly reduces the temperature of the rolled part, shortens the cooling time, and fixes the rolled shape.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
