[0015] BRIEF DESCRIPTION OF DRAWINGS Figures 1 to 3 A device for improving the expansion ratio of adhesive film paper, mainly by discharging device 1, breathing device 2 and impregnation device 3, discharging device 1, breathing device 2 and impregnation device 3 are sequentially arranged on the rack (not shown in the drawing), adhesive film paper M passes through discharging device 1 in turn, passes through the first impregnation section 31 of impregnation device 3, breathing device 2 and the second impregnation section 32, enters the drying device (not shown in the drawing), between breathing device 2 and the second impregnation section 32, expansion ratio improvement device 4 is arranged, the arc surface of the elbow pipe 43 of expansion ratio improvement device 4 abuts against the back of the running adhesive film paper M, so that the middle contact surface of the adhesive film paper M is stressed and the two sides are expanded outwardly with small friction;

[0016] The expansion ratio improvement device 4 is composed of bearing seat 41, connecting rod 42, elbow pipe 43 and adjusting handle 44, the bearing seat 41 is fixed on the rack, the two ends of the connecting rod 42 are rotatably arranged on the bearing seat 41, the arc surface of the elbow pipe 43 is fixed on the connecting rod 42 and faces the back of the adhesive film paper M, and the adjusting handle 44 is fixed on one end of the connecting rod 42;

[0017] The arc surface of the elbow pipe 43 abuts against the back of the running adhesive film paper M;

[0018] The elbow pipe 43 is made of stainless steel;

[0019] The end surface of the adjusting handle 44 is provided with a scale around the end surface;

[0020] The rotation of the adjusting handle 44 can be driven by a stepping motor.

[0021] When applying this utility model, the adhesive film paper M passes through the first impregnation section 31, the breathing device 2, and the second impregnation section 32 of the impregnation device 3 in sequence via the feeding device 1 and enters the drying device. When the adhesive film paper M passes between the breathing device 2 and the second impregnation section 32, it is stretched and narrowed due to the change in height during the process of passing through the breathing device 2. By adjusting the rotation of the handle 44, the connecting rod 42 rotates on the bearing seat 41, which drives the bent tube 43 fixed thereon to rotate. The arc surface of the bent tube 43 abuts against the back of the adhesive film paper M. When the adhesive film paper M passes through, the middle contact is more force-bearing while the friction on both sides is less, so it will expand outward to achieve the purpose of increasing the expansion rate.

[0022] When the material of the adhesive film paper M is different (expansion parameters), the expansion parameters of the adhesive film paper M can be adjusted by adjusting the rotation angle of the handle 44.
