Description

Technical Field

[0001] This utility model relates to the field of stone paper thermoplastic technology, specifically a stone paper board secondary heating and shaping equipment. Background Technology

[0002] Stone paper, also known as "eco-friendly paper" or "mineral paper," has a relatively simple raw material composition. Its core is inorganic mineral powder and high molecular polymer. It does not rely on plant fibers, wood, reeds, etc., used in traditional papermaking, so it has significant environmental protection characteristics. Its raw materials can be divided into two categories: main raw materials and auxiliary raw materials.

[0003] The molten stone paper is extruded into a thick sheet through an extruder die and then enters a multi-roll calender. The roller temperature is slightly lower than the melting temperature, about 80-120℃. The thick sheet is calendered into a product with uniform thickness by the pressure of the rollers. During this process, the stone paper is not fully shaped and is relatively soft, which makes it impossible to completely flatten the surface of the stone paper in one go. Therefore, the existing technology is optimized and improved, and a cost application is submitted. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: A secondary heating and shaping device for stone paperboard includes a housing, a control terminal, and a primary thermoplastic roller assembly. The housing is equipped with drive and transmission components, which are controlled by the control terminal to rotate the roller assembly. The primary thermoplastic roller assembly consists of multiple rollers, with a primary thermoplastic heating rod positioned between adjacent rollers. The housing is also equipped with a glue-applying component located in the subsequent processing step of the primary thermoplastic roller assembly. The glue application component includes a laser contour scanning sensor, glue nozzles, a control valve, and a glue tank. The housing contains a laser contour scanning sensor capable of scanning the contour of the stone cardboard surface and glue nozzles for glue application. The laser contour scanning sensor and glue nozzles are arranged in a line. Multiple glue nozzles are connected to the glue tank through the control valve, and the control terminal is electrically connected to the laser contour scanning sensor and the control valve, respectively.

[0006] As a further improvement of this utility model: the housing is also equipped with an air-cooling system located in the post-processing step of the glue-applying component; The air-cooled system consists of multiple air boxes, air valves, air heaters and fans. The air heaters and fans are controlled by a control terminal. The air boxes are fixedly installed inside the box with the air outlets facing the stone cardboard. The fans, air heaters, air valves and air boxes are connected in sequence through pipelines.

[0007] As a further embodiment of this utility model: the output end of the air heater is provided with an air blowing pipeline connected to the control valve through an air valve and pipeline. The control valve is a three-way valve.

[0013] Please see Figure 1 and 2In this embodiment of the utility model, a secondary heating and shaping device for stone paperboard includes a housing, a control terminal 1, and a primary thermoplastic roller group 2. The housing is equipped with drive and transmission components. The control terminal 1 controls the drive and transmission components to drive the roller group to rotate. The primary thermoplastic roller group 2 consists of multiple rollers. A primary thermoplastic heating rod 3 is arranged between two adjacent rollers. The housing is also equipped with a glue-applying component located in the subsequent processing step of the primary thermoplastic roller group 2. The housing, drive, transmission components, control terminal 1, and roller group are all existing technologies and are accessories and functions of multi-roll calenders, which will not be described in detail here. The glue application component includes a laser contour scanning sensor 4, glue nozzles 6, a control valve 5, and a glue tank 10. The housing contains the laser contour scanning sensor 4, which scans the contour of the stoneboard surface, and the glue nozzles 6, used for glue application. Both the laser contour scanning sensor 4 and the glue nozzles 6 are arranged in a line. Multiple glue nozzles 6 are connected to the glue tank 10 via the control valve 5. The control terminal 1 is electrically connected to both the laser contour scanning sensor 4 and the control valve 5. The laser contour scanning sensor 4 projects a laser line onto the surface of the board. The camera captures the deformation of the reflected light, and the surface height difference is calculated using triangulation to determine whether the stoneboard surface is flat. If there are dents or scratches, the control end 1 controls the spray nozzle 6 to spray out a certain amount of thermoplastic, which can be polyethylene or polypropylene, stored in the glue tank 10. The glue tank 10 has a certain air pressure and a constant temperature preservation function. When the control valve 5 is opened, the air pressure pushes the thermoplastic out and squeezes it onto the stone cardboard, filling the missing part in one go. The primary thermoplastic heating rod 3 and the primary thermoplastic roller group 2 in the front part of the glue filling part can initially soften the surface of the stone cardboard. After the primary thermoplastic roller group 2 is rolled and repaired, it can effectively treat some shallow pits and scratches and dents that do not need glue filling, reducing the workload of the glue filling part.

[0014] In a preferred embodiment, the housing is also equipped with an air-cooling system located in the post-processing step of the glue-applying component; The air-cooling system consists of multiple air boxes 7, air valves 12, air heaters 13, and fans 14. The air heaters 13 and fans 14 are controlled by the control terminal 1. The air boxes 7 are fixedly installed inside the box body with their air outlets facing the cardboard. The fans 14, air heaters 13, air valves 12, and air boxes 7 are connected in sequence through pipelines. In order for the thermoplastic to be extruded smoothly from the pipelines and the glue nozzles 6, it is stored at a constant temperature inside the glue tank 10. Therefore, the extruded thermoplastic has a high temperature and slow setting. By controlling the temperature through the air-cooling system, it can be made to have a certain plasticity and not stick to the rollers when it enters the subsequent secondary thermoplastic process.

[0015] In a preferred embodiment, the output end of the air heater 13 is connected to a control valve 5 via an air valve 12 and a pipeline. The control valve 5 is a three-way valve. The air blowing pipeline and the glue tank 10 are connected to the two input ends of the control valve 5. The output end of the control valve 5 is connected to the glue spray nozzle 6. A shaping air box 11 is also provided in the housing for the secondary thermoplastic processing step. The shaping air box 11 is connected to the output end of the air heater 13 via a pipeline and an air valve 12. The glue spray nozzle 6 itself does not have a heating function. After the thermoplastic is extruded, there is residual thermoplastic hanging on the wall and leaking inside, which causes the internal thermoplastic to cool and solidify, blocking the nozzle opening. Therefore, the control valve 5 is controlled by the control terminal 1 to switch the pipeline. After the glue extrusion is completed, the system switches to the air path. The higher temperature gas is blown out through the pipeline of the glue spray nozzle 6. This can promote the spraying out of the residual glue inside the pipeline and heat the inside of the glue spray nozzle 6 and the pipeline to prevent the thermoplastic from solidifying and blocking.

[0016] In a preferred embodiment, the housing is further provided with a secondary thermoplastic roller group 8 and a secondary thermoplastic heating rod 9 located in the downstream processing step of the air-cooling system. The secondary thermoplastic roller group 8 consists of multiple rollers, and a secondary thermoplastic heating rod 9 is provided between two adjacent rollers. The thermoplastic after cooling cannot completely fuse with the original stone paper surface, so repeated heating and rolling are required. This process results in a thin layer on the surface of the hot-melted stone paperboard, which does not significantly affect the thickness of the stone paperboard. However, it can fuse the original stone paperboard surface and the hot-melted adhesive together well through hot melting, achieving a smooth and integrated surface after rolling.

[0017] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0018] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
