Description

Technical Field

[0001] This utility model relates to the field of unwinding device technology, specifically an electroplated metal coating unwinding device. Background Technology

[0002] When metal parts are processed by electroplating or other methods, a coating operation is required to protect their surface. Generally, the coating device is used in conjunction with the film unwinding and rewinding device. After a roll of film is unwound from the unwinding device, the coating device and the unwinding and rewinding device need to be stopped. The end of the remaining old film is then bonded to the end of the new film on another roll to complete the film splicing and roll changing before the coating operation continues. The above process usually needs to be completed manually, which makes the coating operation discontinuous and affects the coating production efficiency. Utility Model Content

[0033] Two sets of film splicing and roll changing mechanisms are arranged on the device support, including a material strip gripping structure 3, a receiving tray 4, a film pressing structure 5, an adhesive spraying structure 6, and a film cutting structure 7. The material strip gripping structure 3 grips the new film on the corresponding first unwinding tray 1 or second unwinding tray 2 and moves the new film to the surface of the receiving tray 4. The film pressing structure 5 presses the new film onto the receiving tray 4. The receiving tray 4 conveys the new film toward the film cutting structure 7. The adhesive spraying structure 6 sprays adhesive onto the surface of the film. The film cutting structure 7 cuts the old film that is about to be used up and presses its end together with the end of the new film to realize film splicing and roll changing.

[0034] The guide roller 8, which is mounted on the device support, works in conjunction with the external winding device to transport the film drawn out by the film cutting structure 7 to the subsequent coating process.

[0035] The material belt gripping structure 3 includes a rotating shaft 31 and a swing arm 32. The rotating shaft 31 is rotatably mounted on the device support by a first servo motor 33. The swing arm 32 is positioned on the side of the rotating shaft 31, and a first suction port is provided on its end face. The first suction port is connected to an external negative pressure generating device through a first air extraction connector 34.

[0036] The receiving tray 4 includes a cylinder 41. A suction nozzle 42 is provided on the surface of the cylinder 41 to communicate with the inner cavity 43 of the cylinder 41. The inner cavity 43 is connected to an external negative pressure generating device through a second air extraction connector 44. The cylinder 41 is rotatably mounted on the device support by a second servo motor 45.

[0037] The pressure plate structure 5 includes a pressure plate 51, the arc-shaped end face of which matches the surface of the receiving tray 4. It is mounted on a base 52. The output shaft of the first linear drive device 53 on the device support is connected to the base 52, which drives the pressure plate 51 to move toward the receiving tray 4.

The film-cutting structure 7 includes a movable seat 71 and a film-cutting knife 74. The movable seat 71 is slidably mounted on the second linear drive device 72 on the device support, and a second suction port is provided thereon. The third air extraction connector 73 on the movable seat 71 is connected to the second suction port and an external negative pressure generating device.

[0039] The cutting blade 74 slides through the movable base 71, and the third linear drive device 75 on the movable base 71 drives the cutting blade 74 to move out of or into the movable base 71. The aforementioned linear drive device is one or more of a linear motor, electric cylinder, pneumatic cylinder, hydraulic cylinder, or other linear drive devices or mechanisms.

[0040] The working principle of the electroplating metal coating unwinding device in this embodiment includes: when the film on one unwinding reel is almost used up, taking the second unwinding reel 2 as an example, when the roll on it is almost unwound, refer to... Figure 1-6 As shown, the second linear drive device 72 on the left drives the moving seat 71 to move toward the moving seat 71 on the other side, the two moving seats 71 close, the second suction port on the right moving seat 71 adsorbs the film, and the third linear drive device 75 on one side drives the film cutter 74 to move out of the moving seat 71 to cut the film on the right side. After that, the structure resets. At the same time, the first servo motor 33 on the left drives the rotating shaft 31 to rotate, so that the swing arm 32 moves to the surface of the new roll on the left and adsorbs the end of the new film through the first suction port. After that, the rotating shaft 31 rotates in the opposite direction, the swing arm 32 brings the new film to the surface of the receiving tray 4 on the left, the first linear drive device 53 on the left drives the pressure plate 51 to move, so that it presses the new film onto the cylinder 41 on the left, the suction nozzle 42 adsorbs the new film, so that the new film is partially positioned on the cylinder 41. Then, the pressure plate 51 resets. Specifically, as shown in the figure. Figure 1-3 As shown in the structural changes; the second servo motor 45 drives the cylinder 41 to rotate, causing the end of the new film to move down between the two moving seats 71. During this period, the adhesive spraying structure 6 sprays adhesive onto the end of the new film. Then, the two moving seats 71 close again, causing the ends of the new film and the old film to adhere and align, realizing fully automated, continuous, and non-stop film reeling and coating operations, improving the efficiency of the coating process. Afterward, the structure resets, and the film is unwound through the first unwinding reel 1 on the left, as shown in the diagram. Figure 4 , 6 The structural changes are shown in the diagram. The film splicing and roll changing process after the material roll on the left unwinding reel is completed is the same as the steps above, and will not be described in detail here.
