[0038] The roller pressing mechanism 200 is connected to the triangular side plate 2 via a cylinder adjusting mechanism 300 which can adjust the distance between the roller pressing mechanism 200 and the bottom film.

[0039] The mobile frame mechanism 400 includes a mobile frame 401, which is fixedly mounted on the top of the welding frame 1, and a guide rail 402 is fixedly connected to the upper left side of the welding frame 1;

[0040] A fixed seat 403 is slidably connected to the movable frame 401, and the left side of the outer wall of the fixed seat 403 is fixedly connected to the right side of the outer wall of the triangular side plate 2;

[0041] The base film placement table 100 includes a plurality of rotating seats 101 and an optical axis 103. The rotating seats 101 are fixedly mounted on the left side of the outer wall of the triangular side plate 2, and the optical axis 103 is rotatably connected to the rotating seats 101.

[0042] A fixing ring 102 is fixedly installed on the right side of the outer wall of the rotating seat 101, and an adjusting ring 104 is slidably connected to the left side of the outer wall of the optical axis 103, and the adjusting ring 104 can be locked;

[0043] A support rod is fixedly connected to the left side of the outer wall of the triangular side plate 2, and a frame 105 is fixedly connected to the left end of the support rod;

[0044] The left end of the optical axis 103 is rotatably connected to the frame 105, and the acute angle is set to 18 degrees;

[0045] The roller pressing mechanism 200 includes a mounting plate 203, which is fixedly connected to the left side of the outer wall of the triangular side plate 2, and a pair of guide seats 204 are symmetrically fixedly connected to the front side of the mounting plate 203, and a guide shaft 205 is slidably connected to the bottom of the guide seat 204, and a spring 206 is sleeved on the outer wall of the guide shaft 205, and the two ends of the spring 206 are respectively fixedly connected to the bottom of the guide seat 204 and the top of the roller fixing frame 202, and the bottom of the guide shaft 205 is fixedly connected to the roller fixing frame 202, and the roller 201 is rotatably connected to the roller fixing frame 202;
