[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A coating die head level measurement and adjustment device comprises a processing table 1, a backing roller 2 is rotatably connected to the top of the processing table 1, and a coating die head 4 is arranged through a carrier 3, and a measuring component 5 for detecting the levelness is provided on the top of the coating die head 4;

[0023] A leveling component 6 is further provided below the carrier 3 , and the leveling component 6 is used in conjunction with the measuring component 5 to adjust the horizontality of the coating die head 4 .

[0024] Furthermore, the measuring component 5 includes a flat plate 51 , which is fixed on the top of the coating die 4 , and a level 52 and a camera 53 are fixedly connected to the top of the flat plate 51 . The camera 53 is used to monitor the bubble changes of the level 52 .

[0025] It should be added that the camera 53 is externally connected to an image processor, wherein the servo motor 66, the image processor and the camera 53 are connected by wires. Specifically, once the coating die 4 is tilted and not level, the bubble in the spirit level 52 moves beyond the scale range, and the picture captured by the camera 53 is transmitted to the image processor. The processor then sends a current signal of corresponding intensity according to the degree of bubble offset from the center scale value. After receiving the signal, the servo motor 66 makes corresponding level adjustments to the coating die 4 until the bubble in the spirit level 52 reaches the center position.

[0026] Furthermore, the leveling assembly 6 includes a support plate 61, the coating die head 4 is fixed above the support plate 61, and guide parts 62 are fixedly connected on both sides of the bottom thereof, a pair of the guide parts 62 are provided with sliding parts 63 at the free ends, and a limiting rod 64 fixedly connected to the support plate 61 is also provided on the opposite side.

[0027] It is worth mentioning that the guide part 62 is a rod-shaped structure, and the sliding member 63 is a pulley. The pulley is rotatably connected to the free end of the guide part 62 to reduce friction. A pair of the guide parts 62 are arranged relative to each other along the center line of the support plate 61, and the guide part 62 and the support plate 61 are rotatably connected to swing left and right.

[0028] In more detail, it also includes an adjusting member 65 and a servo motor 66. The adjusting member 65 and the servo motor 66 are fixed on the top of the processing table 1. The adjusting member 65 includes a pair of limiting parts 652 fixed above the base 651. The pair of limiting parts 652 are slidably connected with a supporting part 653, and a receiving groove is formed between the limiting part 652 and the supporting part 653.

[0029] In general, the shaft end of the servo motor 66 is fixedly connected to a ball screw 661, the ball screw 661 passes through the limiting portion 652 and is threadedly connected to the abutting portion 653, wherein a through groove 54 and a limiting groove 55 are also provided on the top of the carrier 3.

[0030] Specifically, if there are slight fluctuations in the ground in different areas of the production workshop, and the surface of the carrier 3 is not completely level or vibrates, which affects the levelness of the coating die 4, the levelness adjustment can compensate for the unevenness and ensure a stable coating process.

[0031] The image processor sends a current signal of corresponding strength according to the degree of bubble deviation from the center scale value. After receiving the signal, the servo motor 66 drives the ball screw 661 to rotate. The ball screw 661 is rotatably connected to the limiter 652 and drives the abutment 653 to move toward the side of the coating die 4 that needs adjustment through the thread.

[0032] When the abutment part 653 moves, it contacts the sliding part 63 and then drives the guide part 62 to drive one end of the support plate 61 to rise until the bubble of the level reaches the center position, and the abutment part 653 and the base 651 are limitedly slid between them through a slider or a slide rod.

[0033] In addition, the guide portion 62 is provided in the accommodating groove through the through groove 54 , and slides against the abutting portion 653 through the sliding member 63 , and the limiting rod 64 is movably connected in the limiting groove 55 .

[0034] It is worth mentioning that the limiting groove 55 is a straight groove, and the limiting rod 64 cooperates with the limiting portion 652 to support and guide the coating die head 4, and the limiting rod 64 uses the straight groove to avoid being stuck with the carrier 3.

[0035] Finally, the side of the coating die head 4 is rotatably connected to a fixing member 67, which has an L-shaped structure and the other end of which is fixedly connected to the carrier 3. The fixing member 67 is used to limit and fix the coating die head 4 to prevent the coating die head 4 from moving during leveling.

[0036] In addition, there is a certain gap between the support plate 61 and the carrier 3 , and the gap is used to provide a movable space for the leveling of the coating die head 4 .

[0037] Working mode; During operation, the coating die head 4 is tilted and not level, the bubble of the spirit level 52 moves beyond the scale range, the picture captured by the camera 53 is transmitted to the image processor, and then the processor sends a current signal of corresponding strength to the servo motor 66 according to the degree of bubble offset center scale value;

[0038] The servo motor 66 drives the ball screw 661 to rotate, and the ball screw 661 drives the abutment part 653 to move toward the side of the coating die head 4 that needs to be adjusted through the thread. When the abutment part 653 moves, it contacts the sliding part 63 and then drives the guide part 62 to drive one end of the support plate 61 to rise until the bubble in the spirit level reaches the center position.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
