A type of board laminating machine

Abstract

This utility model discloses a sheet metal laminating machine, including a frame and a laminating station mounted on the frame. An initial heating device is located below the laminating station, and a heat preservation heating device is also included. The heat preservation heating device is positioned above the laminating station, connected to the frame, and movable relative to the frame. In this design, by installing the heat preservation heating device above the laminating station, the laminating station is continuously heated and kept warm even after the sheet metal leaves the heating range of the initial heating device (i.e., the laminating station) and the initial heating device stops working. This eliminates the waiting time for the initial heating device to restart and heat to the required laminating temperature, thus shortening the laminating time for a single sheet metal and improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, specifically to a sheet metal coating machine. Background Technology

[0002] In the processing of sheet materials, a film is often applied to the surface to improve product quality and aesthetics. Current sheet lamination processes typically require heating the sheet to prevent defects such as bubbles during lamination and to accelerate the bonding and curing of the film between the sheet surface and the lamination. Therefore, existing laminating machines are usually equipped with heat-insulating heating devices to heat the sheet.

[0003] However, the heating and insulation devices on existing laminating machines typically only heat the board as it passes through its heating range, i.e., the laminating station. Once the board leaves the heating range, the heating and insulation devices stop working. This causes the equipment temperature at the laminating station to drop after the board leaves, especially in low ambient temperatures. The temperature at the laminating station drops rapidly to a level insufficient for lamination. When subsequent boards enter the laminating station, the heating and insulation devices must restart, and the equipment temperature must be raised to the required lamination temperature before lamination can begin. This easily leads to prolonged lamination time for individual boards, resulting in reduced production efficiency. Furthermore, the heating and insulation devices on existing laminating machines typically heat the entire board, preventing the flexible heating of individual areas during the lamination process to quickly address localized issues.

[0004] This shows that existing technologies still have certain shortcomings. Utility Model Content

[0005] The purpose of this utility model is to provide a board laminating machine to solve at least one of the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides a sheet laminating machine, which includes a frame and a laminating station disposed on the frame. An initial heating device is disposed below the laminating station, and a heat preservation heating device is also provided. The heat preservation heating device is disposed above the laminating station, and is connected to the frame and is movable relative to the frame.

[0007] In the above solution, by clamping a heat preservation and heating device above the laminating station, the laminating station can be continuously heated and kept warm after the board leaves the heating range of the original heating device (i.e., the laminating station) and the original heating device stops working. This eliminates the waiting time for the original heating device to restart and heat to the temperature required for laminating, which helps to shorten the working time required for laminating a single board and improve production efficiency.

[0008] In a preferred embodiment of this application, the frame is provided with a first mounting part and a second mounting part located above the first mounting part, the film coating station is provided in the first mounting part, and the heat preservation and heating device includes a hot air device provided in the second mounting part, the hot air device having a hot air outlet.

[0009] In the above scheme, using a hot air device as a heat preservation and heating device can achieve basic heating and heat preservation functions. On the other hand, compared with heating methods such as electric heating, hot air heating can extend the heating distance, avoid the heat preservation and heating device being too close to the conveying path of the board and causing interference to the conveying of the board, and also reserve sufficient operating space for the board lamination. In addition, using hot air heating can also help reduce the probability of problems such as bubbles and wrinkles during the lamination process by blowing hot air.

[0010] As a preferred embodiment of this application, it further includes an air guiding device, which includes an air guiding bracket connected to the hot air device and / or the frame and an air guiding channel disposed on the air guiding bracket. The air guiding channel has an air inlet communicating with the hot air outlet and an air outlet facing the film coating station.

[0011] In the above solution, the direction of hot air can be adjusted by setting up an air guide device. The direction of hot air blowing can be adjusted according to factors such as the specifications and shape of the board and other actual processing needs, so as to ensure the quality and efficiency of the coating.

[0012] In a preferred embodiment of this application, the air outlet is provided with an air volume control component, which is used to control the opening and closing of the air outlet and the opening area of ​​the air outlet.

[0013] In the above solution, controlling the opening area of ​​the air outlet through the air volume control component can effectively adjust the hot air volume passing through the air outlet, thereby adjusting the heat output of the heat preservation and heating device. This makes it easier to adjust the working condition of the hot air device according to the working condition of the original heating device, and avoid overheating of the film coating station from affecting the normal film coating work.

[0014] In a preferred embodiment of this application, the air outlet is movably connected to the air guide bracket.

[0015] With the above-mentioned configuration, the movable air outlet facilitates adjustment of the distance between the air outlet and the board, as well as the direction of the air outlet. Combined with the control of the hot air volume passing through the air outlet, it allows for more flexible adjustment of the heat output of the heat preservation and heating device and the heating efficiency of the heat preservation and heating device on the film coating station.

[0016] In a preferred embodiment of this application, the air guide channel includes a fixed section and a flexible section that are interconnected. The fixed section is provided with the air inlet, and the flexible section is provided with the air outlet.

[0017] With this configuration, the fixed section is fixedly connected to the hot air device, and the movement of the air outlet will not affect the matching structure between the air inlet and the hot air device. This helps to ensure the stability of the connection structure between the air guide channel and the hot air device while ensuring the flexible movement of the air outlet.

[0018] As a preferred embodiment of this application, a monitoring component is also included, the monitoring component comprising a first temperature measuring element for monitoring ambient temperature and a second temperature measuring element for monitoring the temperature of the coating station.

[0019] In a preferred embodiment of this application, a controller is also included, which is electrically connected to the first temperature measuring element, the second temperature measuring element, the air volume control element, and the hot air device, respectively.

[0020] In a preferred embodiment of this application, the air guiding device further includes a branch guide hose connected to the fixed section, wherein the end of the branch guide hose away from the fixed section has a movable branch air outlet.

[0021] In the above solution, the use of branch guide hoses facilitates the operation of the laminating personnel to address issues such as bubbles and wrinkles that occur in certain areas of the board during the laminating process.

[0022] In a preferred embodiment of this application, a control switch is provided at the connection between the branch hose and the fixed section. Attached Figure Description

[0031] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0032] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-2 As shown, this application provides a board laminating machine, which includes a frame 1, a laminating station 11 disposed on the frame 1, and a heating device disposed below the laminating station 11. It also includes a heat preservation heating device disposed above and / or below the laminating station 11, connected to the frame 1, and movable relative to the frame 1. In this solution, by clamping the heat preservation heating device above the laminating station 11, the laminating station 11 can be continuously heated and kept warm even after the board leaves the original heating range (i.e., the laminating station 11) and the original heating device stops working. This eliminates the waiting time for the original heating device to restart and heat to the required laminating temperature, thus shortening the working time required for laminating a single board and improving production efficiency.

[0034] Furthermore, referring to Figure 1As shown, the frame 1 is provided with a first mounting part 12 and a second mounting part 13 located above the first mounting part 12. The laminating station 11 is located on the first mounting part 12. The heat preservation and heating device includes a hot air device 2 located on the second mounting part 13, and the hot air device 2 has a hot air outlet 21. Using the hot air device 2 as the heat preservation and heating device can achieve basic heating and heat preservation functions. On the other hand, compared with heating methods such as electric heating, hot air heating can extend the heating distance, avoid the heat preservation and heating device being too close to the conveying path of the board and interfering with the conveying of the board, and also reserve sufficient operating space for the laminating of the board. In addition, using hot air heating can also help reduce the probability of problems such as bubbles and wrinkles during the laminating process by blowing hot air. In a preferred example, an air conditioner is used as the hot air device 2. The air conditioner can be used as a hot air device 2 in a low-temperature environment, or as a cold air device in a high-temperature environment to adjust the temperature of the laminating station 11 to the optimal working temperature. Of course, this is only a preferred example of this application. This application does not specifically limit the type and structure of the hot air device 2, and it can also adopt other different types of hot air devices 2.

[0035] As a preferred embodiment of this application, the sheet laminating machine further includes an air guiding device. The air guiding device includes an air guiding bracket 33 connected to the hot air device 2 and / or the frame 1, and an air guiding channel 3 disposed on the air guiding bracket 33. The air guiding channel 3 has an air inlet communicating with the hot air outlet 21 and an air outlet 321 facing the laminating station 11. Preferably, referring to… Figure 1 As shown, the air guide bracket 33 is mounted on the hot air device 2. By setting the air guide device, the direction of the hot air can be adjusted. The direction of the hot air blowing can be adjusted according to factors such as the specifications and shape of the board and other actual processing requirements to ensure the quality and efficiency of the coating.

[0036] Furthermore, the air outlet 321 is equipped with an airflow control component 322, which is used to control the opening and closing of the air outlet 321 and the opening area of ​​the air outlet 321. In the above scheme, controlling the opening area of ​​the air outlet 321 through the airflow control component 322 can effectively adjust the hot air volume passing through the air outlet 321, thereby adjusting the heat output of the heat preservation and heating device. This facilitates adjusting the operating conditions of the hot air device 2 according to the original operating conditions of the heating device, and avoids overheating of the laminating station 11 from affecting the normal laminating work. In one example, refer to... Figure 2As shown, the airflow control element 322 consists of two baffles located at the air outlet 321. In use, the relative position of the two baffles is adjusted to change the gap between them, thereby adjusting the opening size of the air outlet 321. It should be noted that the airflow control element 322 in this application is not limited to the example described above; other structural forms of airflow control elements 322, such as flaps, can also be used. This application does not impose any specific limitations on this.

[0037] Furthermore, in a preferred embodiment of this application, the air outlet 321 is movably connected to the air guide bracket 33. The movable arrangement of the air outlet 321 facilitates adjustment of the distance between the air outlet 321 and the board material, as well as the orientation of the air outlet 321. Combined with the control of the hot air volume passing through the air outlet 321, the heat output of the heat preservation and heating device and the heating efficiency of the heat preservation and heating device on the film coating station 11 can be adjusted more flexibly.

[0038] In one example, refer to Figure 1 As shown, the air guide channel 3 includes a fixed section 31 and a flexible section 32 that are interconnected. The fixed section 31 is provided with an air inlet, and the flexible section 32 is provided with an air outlet 321. With this arrangement, the fixed section 31 is fixedly connected to the hot air device 2, and the movement of the air outlet 321 will not affect the mating structure between the air inlet and the hot air device 2. This helps to ensure the stability of the connection structure between the air guide channel 3 and the hot air device 2 while ensuring the flexible movement of the air outlet 321.

[0039] Continue to refer to Figure 1 As shown, the air guiding device also includes a branch guide hose 34 connected to the fixed section 31. The end of the branch guide hose 34 furthest from the fixed section 31 has a movable branch air outlet. A control switch is provided at the connection point between the branch guide hose 34 and the fixed section 31. The branch guide hose 34 allows the laminating operator to operate it as needed to address issues such as bubbles and wrinkles that occur locally on the board during the laminating process.

[0040] Furthermore, the board laminating machine of this application also includes a monitoring component and a controller. The monitoring component includes a first temperature measuring element for monitoring the ambient temperature and a second temperature measuring element for monitoring the temperature of the laminating station 11. The controller is electrically connected to the first temperature measuring element, the second temperature measuring element, the airflow control element 322, and the hot air device 2. The monitoring component facilitates real-time acquisition of the ambient temperature and the temperature of the laminating station 11. Simultaneously, in conjunction with the controller, it enables automatic control of the hot air device 2's operating status. Preferably, the airflow control element 322 is also controlled in conjunction with the controller, thereby significantly improving the automation level of the board laminating machine of this application and reducing reliance on manual labor intensity and experience.
