[0021] Specifically, mounting frames 401 are fixedly provided on both sides of the protection box 1 .

[0022] In this embodiment, by providing a protective box 1 and a mounting frame 401, the protective box 1 can be erected above the tape using the mounting frame 401 so that the bottom of the pressure roller 404 fits the tape to squeeze and remove excess adhesive on the tape surface.

[0023] Specifically, the four corners of the bottom of the protection box 1 are fixedly provided with fixed seats 402 , a horizontal plate 403 is fixedly provided between the fixed seats 402 on the same side, and a pressure roller 404 is movably provided between the two horizontal plates 403 .

[0024] In this embodiment, by providing a fixed seat 402 , a transverse plate 403 and a pressure roller 404 , the fixed seat 402 provides support for the transverse plate 403 , and the pressure roller 404 rotates between the transverse plates 403 .

[0025] Specifically, a scraper 405 is movably provided on one side of the pressure roller 404 .

[0026] In this embodiment, by setting a pressure roller 404 and a scraper 405, while the pressure roller 404 rotates along the direction of movement of the tape, the scraper 405 will promptly scrape off the adhesive on the surface of the pressure roller 404 to prevent the adhesive on the pressure roller 404 from dripping onto the tape, which is also beneficial to the long-term use of the pressure roller 404.

[0027] Specifically, the scraper 405 has a certain inclination angle, and one end close to the pressure roller 404 is higher than the other end thereof. A storage box 406 is fixedly provided on one side of the top of the scraper 405 .

[0028] In this embodiment, by setting a scraper 405 and a storage box 406, since the scraper 405 is placed at an angle, the adhesive scraped by the scraper 405 will flow to the side of the scraper 405 away from the pressure roller 404, and then enter the storage box 406, so that the storage box 406 collects the adhesive for easy processing of the adhesive.

[0029] Specifically, a drain pipe 407 is fixedly disposed at the bottom of the storage box 406 , and the drain pipe 407 passes through the top of the scraper 405 and extends to the bottom of the scraper 405 .

[0030] In this embodiment, a storage box 406 and a drain pipe 407 are provided, and the adhesive scraped off by the scraper 405 on the surface of the pressure roller 404 is collected in the storage box 406. When the storage capacity of the storage box 406 is about to be full, the drain pipe 407 is opened to clean the storage box 406 to ensure that the adhesive in the storage box 406 does not overflow.

[0031] When in use, the protective box 1 is set up above the tape using the mounting frame 401, so that the bottom of the pressure roller 404 fits the tape. When the tape moves, the pressure roller 404 squeezes the tape to evenly distribute the adhesive on the tape. The pressure roller 404 rotates along the direction of the tape movement, while carrying away the excess adhesive. The fan 203 and the heating plate 207 are turned on, and the fan 203 draws air into the air inlet pipe 202. The air is filtered by the filter screen 302 in the filter box 201 and then enters the air outlet pipe 204, and then is discharged from the bottom of the air collecting pipe 205. The gas blown out by the blowing pipe 206 flows downward, and at the same time, the heat generated by the heating plate 207 is driven downward. The adhesive is subjected to the hot air, which accelerates the solidification speed of the adhesive and prevents the adhesive from dripping. The scraper 405 will also scrape the adhesive on the surface of the pressure roller 404 in time to ensure the long-term use of the pressure roller 404. The adhesive on the scraper 405 will be retained in the storage box 406, which will collect the adhesive and make it flow out through the drain pipe 407, so as to facilitate the treatment of the adhesive.

[0032] When the filter 302 needs to be cleaned, the vibration motor 304 is started, and the vibration motor 304 drives the transmission block 303 to start vibrating. The sliders 307 at both ends of the filter 302 squeeze the return spring 308. The elastic force of the return spring 308 causes the filter 302 to vibrate and shake the dust on the filter 302 into the dust box 305. Then the handle 306 is pulled to take out the dust box 305, so that the dust in the dust box 305 is exhausted, and then the dust box 305 is put back into the filter box 201.

[0033] In summary, the coating machine uses a uniform coating device, which is provided with a filter box 201, a heating plate 207 and a filter screen 302. The gas drawn in by the fan 204 enters the air outlet pipe 203 after passing through the filter box 201 from the air inlet pipe 202. The filter screen 302 in the filter box 201 can filter dust or impurities in the air, reduce the influence of dust or impurities on the coating, enhance the coating effect, and improve the performance of the device. The heating of the heating plate 207 generates heat, so that the gas blown out from the blowing pipe 206 at the bottom of the air collecting pipe 205 becomes hot air, thereby drying the adhesive, allowing the adhesive to solidify quickly, avoiding the adhesive from dripping, and facilitating the adhesive to be coated. To collect dust, a transmission block 303, a vibration motor 304, a dust box 305, a handle 306 and a return spring 308 are provided. After the vibration motor 304 is powered on and started, the transmission block 303 is driven to vibrate synchronously. At the same time, the sliders 307 at both ends of the filter 302 squeeze the return spring 308, so that the elastic force of the return spring 308 drives the filter 302 to vibrate, and the dust on the filter 302 is shaken off into the dust box 305. The handle 306 is pulled to take out the dust box 305, and the dust in the dust box 305 can be processed, which simplifies the steps of cleaning the filter 302, is conducive to improving work efficiency, and can save manpower and material resources.
