[0027] Both outer walls of the first bracket 2 close to the first coating roller 3 are rotatably connected with rotating shafts 10, the outer walls of the rotating shafts 10 are fixedly connected with adjusting scrapers 11, one end of the adjusting scraper 11 away from the rotating shaft 10 is close to the surface of the first coating roller 3, and a servo motor 12 is fixedly installed on the outer wall of the first bracket 2, the output shaft of the servo motor 12 penetrates through the first bracket 2 and is fixedly connected with one end of the rotating shaft 10;

[0028] A drying component is also installed on the outer wall of the workbench 1, the drying component includes an air shower pipe 1401 and a hot air blower 1404, a diversion port 1402 is arranged on the bottom outer wall of the air shower pipe 1401, and the output end of the hot air blower 1404 is connected with the air shower pipe 1401 through an air supply pipe 1405.

[0029] A glue storage tank 7 is arranged on the top outer wall of the workbench 1 directly below the second coating roller 4, a flow meter 8 is fixedly installed on one outer wall of the first bracket 2, the output end of the flow meter 8 is connected with the coating head 5 through a delivery pipe 9, and the suction end of the flow meter 8 penetrates through the first bracket 2 and extends into the inner cavity of the glue storage tank 7.

[0030] A control unit 13 is installed on one outer wall of the first bracket 2, and both the servo motor 12 and the flow meter 8 are electrically connected to the control unit 13.

[0031] Two second brackets 14 are fixedly connected to the top outer wall of the workbench 1, and both ends of the air shower pipe 1401 are fixedly connected to the opposite outer walls of the two second brackets 14.

[0032] A fixing frame 1403 is fixedly connected to the bottom outer wall of the workbench 1, and the hot air blower 1404 is fixedly installed on the outer wall of the fixing frame 1403.

[0033] Two third brackets 15 are fixedly connected to the outer wall of the top of the workbench 1. A winding roller 1501 is rotatably connected to the opposite outer walls of the two third brackets 15. A driving motor 1502 is fixedly installed on the outer wall of one of the third brackets 15. The output shaft of the driving motor 1502 is connected to one end of the winding roller 1501.

[0034] The implementation principle of the automatic coating structure of the foam tape in the embodiment of the present application is as follows: During actual use, the second coating roller 4 is toggled downward, so that the second coating roller 4 moves downward. The two ends of the second coating roller 4 drive the sliders 202 to move downward. The sliders 202 slide on the outer wall of the limiting rod 203, thereby squeezing the spring 204. The spring 204 deforms to generate an elastic force. At this time, the distance between the first coating roller 3 and the second coating roller 4 increases. One end of the foam tape is passed through between the first coating roller 3 and the second coating roller 4, and the second coating roller 4 is released and wound around the outer wall of the winding roller 1501. At this time, when the second coating roller 4 is not stressed, the two sliders 202 will drive the second coating roller 4 to rise under the elastic force of the spring 204, and the second coating roller 4 and the first coating roller 3 will tightly clamp the tape to adapt to the coating of tapes with different thicknesses;

[0035] After the tape is installed, the coating operation can be carried out. First, the flowmeter 8 is started through the control unit 13. The flowmeter 8 pumps the glue previously added in the glue storage tank 7 into the coating head 5 through the delivery pipe 9, and is sprayed onto the surface of the first coating roller 3 by a plurality of nozzles 6. At the same time, the driving motor 1502 is driven. The output shaft of the driving motor 1502 drives the winding roller 1501 to rotate, and the tape is wound up. When the tape is wound up, it will move to drive the first coating roller 3 and the second coating roller 4 to rotate relatively. When the first coating roller 3 rotates, the glue on its surface is applied to the tape. During the application process, the servo motor 12 can be controlled to start through the control unit 13. The servo motor 12 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the adjusting scraper 11 to rotate, so that the distance between the end of the adjusting scraper 11 and the surface of the first coating roller 3 can be adjusted in real time. When the first coating roller 3 continues to rotate, it will drive the glue to pass through the end of the adjusting scraper 11, and the glue will be leveled by the adjusting scraper 11 and evenly distributed on the surface of the first coating roller 3, thereby realizing the adjustment of the coating thickness of the glue and increasing the uniformity of the coating;

[0036] When the coated tape moves past the lower part of the air shower pipe 1401, the hot air blower 1404 is started. The hot air blower 1404 heats the external air and transports it into the air shower pipe 1401 through the air supply pipe 1405. The hot air is blown onto the tape by the diversion port 1402 to quickly dry the glue, so that the glue is fully cured, improving the durability of the foam tape. As the winding roller 1501 continues to rotate, it drives the coated tape to be wound into a roll, which is convenient for storage and transportation.
