The cutter 271 is used to cut the adhesive tape. A heating nozzle 241 is connected to the heating tube 24 and is used to heat-seal the sewn positions of the protective clothing.

[0025] In this embodiment, a first drive motor 12 is provided at the bottom of the working platform 1. The first drive motor 12 is connected to a first drive wheel 121. A second rolling wheel 13 is coaxially connected to a first driven wheel 131. The first drive wheel 121 and the first driven wheel 131 are connected by a first belt 122.

[0026] In this embodiment, the heating tube 24 is mounted on the mounting frame 25, and a swing cylinder 251 is hinged to the mounting frame 25. The piston rod of the swing cylinder 251 is hinged to the lifting seat 221. A connecting rod 252 is hinged to the mounting frame 25, and the connecting rod 252 is hinged to the lifting seat 221.

[0027] In this embodiment, a lifting guide rail 22 is provided on the frame 2, and a lifting seat 221 is slidably connected to the lifting guide rail 22.

[0028] In this embodiment, a pair of guide wheels 26 are rotatably connected to the frame 2. The two guide wheels 26 are used to roll and convey the adhesive tape between the first rolling wheel 11 and the second rolling wheel 13. A transmission cylinder 29 is provided on the frame 2. The transmission cylinder 29 is connected to a transmission wheel 291. The transmission cylinder 29 is used to drive the transmission wheel 291 to move downward at an angle so that the transmission wheel 291 rolls and connects the first rolling wheel 11 and one of the guide wheels 26 respectively.

[0029] In this embodiment, a plurality of guide frames 231 are provided on the frame 2. The plurality of guide frames 231 are respectively disposed between the unwinding roller 23 and the guide wheel 26. The plurality of guide frames 231 are arranged at intervals from top to bottom. The guide frames 231 are used to guide the conveying of the adhesive tape.

[0030] In this embodiment, a propulsion cylinder 27 is provided on the frame 2, and a cutting seat 272 is provided on the lifting seat 221. The cutting seat 272 is hinged to the cutter 271, and the piston rod of the propulsion cylinder 27 is hinged to the cutter 271. The cutter 271 and the cutting seat 272 cooperate to cut the adhesive tape.

[0031] In this embodiment, a second drive motor 28 is provided on the frame 2. The second drive motor 28 is connected to a second drive wheel 111281. The first rolling wheel 11 is coaxially connected to a second driven wheel. The second drive wheel 111281 and the second driven wheel are connected by a second belt 282.

[0032] In this embodiment, the specific sealing process is as follows: First, the lifting cylinder 21 and the swing cylinder 251 are activated. The piston rod of the lifting cylinder 21 extends and retracts to drive the lifting seat 221, the heating tube 24, and the heating nozzle 241 to move up and down. In conjunction with the extension and retraction of the swing cylinder 251, the mounting bracket 25, the heating tube 24, and the heating nozzle 241 swing until the heating nozzle 241 is aligned between the first rolling roller 11 and the second rolling roller 13.

[0033] Then, the tape on the unwinding roller 23 is pulled. After being guided by multiple guide frames 231, the tape enters between the two guide wheels 26 and is then output from the two guide wheels 26.

[0034] At this time, the first drive motor 12 and the second drive motor 28 are started respectively. The first drive motor 12 drives the first drive wheel 121 to rotate. The first drive wheel 121 drives the first driven wheel 111 to rotate through the first belt 122, so as to drive the second rolling wheel 13 to rotate. The second drive motor 28 drives the second drive wheel 281 to rotate. The second drive wheel 281 drives the second driven wheel 131 to rotate through the second belt 282, so as to drive the first rolling wheel 11 to rotate. Then, the adhesive tape is attached to the sewn position of the protective clothing, and the sewn position of the protective clothing is aligned between the first rolling wheel 11 and the second rolling wheel 13.

[0035] At this time, the heating element 24 and the transmission cylinder 29 are activated respectively. The heating element 24 operates and sprays hot air between the first rolling roller 11 and the second rolling roller 13 through the heating nozzle 241. The piston rod of the transmission cylinder 29 extends to push the transmission wheel 291 to tilt downward, bringing the transmission wheel 291 closer to the first rolling roller 11, until the transmission wheel 291 rolls and connects the first rolling roller 11 with one of the guide wheels 26. This causes the first rolling roller 11 to drive one of the guide wheels 26 to rotate through the transmission wheel 291, so that the first rolling roller 11 and the second rolling roller 13 roll together for protection. During the process, the guide wheel 26 rotates, continuously feeding adhesive tape onto the protective suit. As the protective suit passes through the first roller 11 and the second roller 13, the adhesive tape is continuously applied. The heated nozzle 241 heat-seals the seams of the protective suit after the adhesive tape has been applied. Once the protective suit has completely passed between the first roller 11 and the second roller 13, the propulsion cylinder 27 is activated. The piston rod of the propulsion cylinder 27 extends, causing the cutter 271 to swing. The cutter 271 and the cutting seat 272 work together to cut off the excess adhesive tape, thus achieving the heat-sealing process of the protective suit.

[0036] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any person skilled in the art can make more possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from the content of the technical solution of this utility model should be covered within the protection scope of this utility model.
