DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figure 1-Figure 3 As shown, a film pressing mechanism proposed in this embodiment includes a frame 1 and two embossing mechanisms.

[0022] The frame 1 has a through hole 101; two embossing mechanisms are respectively arranged on the upper and lower sides of the through hole 101, the embossing mechanism includes a mounting shaft 2, a servo motor b12, two mounting frames 4, two mounting side plates 5 and multiple printing rollers 3, the two mounting frames 4 are both mounted on the mounting shaft 2, and the multiple printing rollers 3 are all rotatably mounted between the two mounting frames 4 through a rotating shaft. The printing roller 3 can be a hot roller, and the quality of the embossed pattern is stable, and the multiple printing rollers 3 are arranged in an annular array along the outer periphery of the mounting shaft 2, the two mounting side plates 5 are respectively arranged at both ends of the printing roller 3, the mounting shaft 2 is rotatably mounted between the two mounting side plates 5, the servo motor b12 is mounted on the mounting side plates 5 and its output shaft is connected to the mounting shaft 2, the two mounting side plates 5 on the embossing mechanism at the bottom are both fixedly connected to the frame 1, and two linear drive mechanisms a6 are installed on the frame 1, and the output shafts of the two linear drive mechanisms a6 are respectively connected to the two mounting side plates 5 on the embossing mechanism at the top.

[0023] A rotating sleeve a81 and a rotating sleeve b82 are respectively arranged on both sides of the multiple rotating shafts, wherein the rotating sleeve a81 is rotatably installed on the mounting frame 4 on one side, a spline shaft is connected to one end of the rotating shaft adjacent to the rotating sleeve a81, a spline groove matching the spline shaft is arranged on the inner side of the rotating sleeve a81, the rotating sleeve b82 is threadedly connected to the mounting frame 4 on the other side, and a hand wheel 9 is installed on the outer end of the rotating sleeve b82; the arrangement of the above structure makes it easy to disassemble and assemble the printing roller 3. When the printing roller 3 is disassembled, the rotating sleeve b82 is driven to rotate by the hand wheel 9, so that the end of the rotating shaft is separated from the rotating sleeve b82, and then the other end of the rotating shaft is moved out from the inner side of the rotating sleeve a81, and the operation is relatively simple.

[0024] A cross groove 811 is provided at the outer end of the rotating sleeve a81, and a driving assembly is installed on the mounting side plate 5 adjacent to one side of the rotating sleeve a81 and the frame 1. The driving assembly includes a linear driving mechanism b10, a servo motor a11, a rotating sleeve 13 and a cross block 15. The servo motor a11 is installed on the output shaft of the linear driving mechanism b10, and the rotating sleeve 13 is connected to the output shaft of the servo motor a11. An elastic member is connected between the rotating sleeve 13 and the servo motor a11. The elastic member is a spring 14. The spring 14 is arranged on the inner side of the rotating sleeve 13. A limited slider 16 is slidably arranged on the inner side of the rotating sleeve 13. The rotating sleeve 13 moves through the rotating sleeve 13. The end of the sleeve 13 is connected to the limit slider 16. When replacing the printing roller 3, the linear drive mechanism b10 drives the cross block 15 to move out of the corresponding cross groove 811, and then drives the required printing roller 3 to the specified position, starts the servo motor a11, and initially lowers the speed of the servo motor a11. The linear drive mechanism b10 slowly pushes the servo motor a11, the rotating sleeve 13 and the cross block 15 to move. First, the cross block 15 contacts the end face of the rotating sleeve a81. When the cross groove 811 rotates to align with the cross block 15, the cross block 15 is inserted into the cross groove 811, thereby enabling the printing roller 3 to be driven.

[0025] In this embodiment, the servo motor b12 is controlled by the controller 7, and the servo motor b12 drives the mounting shaft 2 to rotate, thereby driving multiple printing rollers 3 to rotate, so that different printing rollers 3 can be quickly switched to perform embossing work. In order to ensure the rotation accuracy of the mounting shaft 2, an angle sensor can be installed at its end to monitor the rotation angle of the mounting shaft 2; the controller 7 can control the linear drive mechanism a6 to work, and the linear drive mechanism a6 can adjust the lifting height of the top embossing mechanism to meet the embossing requirements of printing rollers 3 with different diameters.

A driving member for driving the two connecting sliders 19 to move closer to or away from each other is installed on the frame 1, and the driving member includes a bidirectional screw rod 18 and a rotating handle 20 installed at the end of the bidirectional screw rod 18. The bidirectional screw rod 18 is rotatably installed on the frame 1, and the two connecting sliders 19 are threadedly connected to the bidirectional screw rod 18.

[0028] In this embodiment, the bidirectional screw rod 18 is driven to rotate by rotating the handle 20, and the rotation direction of the bidirectional screw rod 18 is adjusted to drive the two connecting sliders 19 to move closer to or away from each other. The two connecting sliders 19 respectively drive the limiting rings 17 on both sides to move, thereby realizing the limiting requirements for different composite films.
