[0022] The utility model provides Figure 1-3 A tape coating machine for uniform coating as shown in the figure comprises:

[0023] A chassis 100, with corresponding openings 101 on both sides of the chassis 100, a glue outlet 102 on one side of the chassis 100 and a control cabinet 104 on the other side, a glue collecting bucket 103 directly below the glue outlet 102, a corresponding buffer groove 105 on the inner side wall of the chassis 100, and a damper 106 at the bottom of the buffer groove 105;

[0024] The leveling mechanism 200 includes two correspondingly arranged mounting plates 201, the two mounting plates 201 are fixedly connected by a connecting rod 202, a mounting rod 203 extending into the buffer groove 105 is fixed on one side of the mounting plate 201, when the leveling mechanism 200 is vibrated and impacted downward, the damper 106 in the buffer groove 105 can absorb the impact force and alleviate the vibration, a guide roller 204 is arranged between the two mounting plates 201, a mounting groove 205 is arranged on the mounting plate 201, a mounting frame 206 is fixed in the mounting groove 205, a connecting plate 207 is arranged in the mounting frame 206, and a connecting plate 207 is arranged in the connecting plate 207. A scraper 208 is snap-fitted to the bottom of the plate 207. When the glue on the surface of the scraper 208 solidifies and accumulates, affecting its use, it is convenient to replace it. One end of the scraper 208 extends outward and passes through the glue outlet 102, so that the scraped excess glue can be discharged through the glue outlet 102. An adjusting bolt 209 is provided on one side of the mounting frame 206. One end of the adjusting bolt 209 is movably connected to the connecting plate 207. By turning the adjusting bolt 209, the adjusting bolt 209 can drive the connecting plate 207 to move in the horizontal direction, thereby adjusting the distance between the scraper 208 and the guide roller 204, thereby finally achieving the adjustment of the glue coating thickness.

[0025] In addition, it also includes a driving mechanism 300, which includes a substrate roller 301 and a tape roller 302 arranged on both sides of the chassis 100. A motor 1 303 is provided at one end of the substrate roller 301, and a motor 2 304 is provided at one end of the tape roller 302. The motor 1 303 drives the substrate roller 301 to rotate, and continuously transports the tape substrate into the chassis 100. The motor 2 304 drives the tape roller 302 to rotate, and continuously rewinds the glue-coated tape from the chassis 100 onto the tape roller 302.

[0026] Specifically, it also includes a coating mechanism 400, which includes a glue box 401 fixed on the top surface of the chassis 100, a glue hose 402 is provided at the bottom of the glue box 401, a water pump 403 is provided on one side of the glue box 401, the water outlet pipe of the water pump 403 is sealedly connected to the glue hose 402, and a nozzle 404 is provided at the bottom end of the glue hose 402, which can pump the glue in the glue box 401 to the glue hose 402 through the water pump 403, and then spray it on the tape substrate through the nozzle 404.

[0027] It is worth mentioning that a drying mechanism 500 is also included. The drying mechanism 500 is fixed to the inner top surface of the chassis 100. Inside the drying mechanism 500, there are heating wires 501 and a blower 502. The blower 502 blows the air heated by the heating wires 501 towards the tape substrate, which can accelerate the air-drying speed of the glue and facilitate the quick winding of the tape.

[0028] Specifically, the scraper 208 is inclined, which is convenient for scraping the excess glue on the tape substrate and flowing along the scraper 208 into the glue collecting bucket 103 to prevent the excess glue from accumulating on the scraper 208. The cutting edge of the scraper 208 is an arc structure, so that different positions of the cutter head of the scraper 208 can maintain the same distance from the tape substrate on the guide roller 204, which is beneficial to scraping the glue on the tape substrate to the same thickness by the scraper 208.

[0029] It should be noted that a rotating motor 405 is provided at the top of the glue tank 401. Inside the glue tank 401, there is a rotating shaft 406. The top end of the rotating shaft 406 extends outside the glue tank 401 and is key-connected to the output shaft of the rotating motor 405. Stirring blades 407 are fixed around the rotating shaft 406. By driving the rotating shaft 406 to rotate through the rotating motor 405, the glue in the glue tank 401 is stirred by the stirring blades 407, which is beneficial to preventing the glue from stratifying.

[0030] Specifically, there are three guide rollers 204 in total. The three guide rollers 204 are distributed in a "pin" shape. The tape substrate is wound around the guide rollers 204 in sequence to ensure that the tape substrate can always be in contact with the guide rollers 204. The guide roller 204 located above coincides with the central axis plane of the mounting frame 206 to ensure that the scraper 208 on the mounting frame 206 corresponds to the upper guide roller 204. The horizontal position of the scraper 208 is adjusted by the adjusting bolt 209, and then the distance between the scraper 208 and the upper guide roller 204 can be adjusted. The bottom cross-section of the guide roller 204 located below penetrates through the through hole 101 to ensure that the tape substrate and the tape can enter and exit the chassis 100 through the through hole 101.

[0031] Working principle: When the tape coater with uniform coating is in use, first, the tape substrate on the substrate roller 301 passes through the chassis 100 and winds around the tape roller 302. Then, the first motor 303 and the second motor 304 are started simultaneously, so that the tape substrate can be continuously wound from the substrate roller 301 to the tape roller 302. During the transportation of the tape substrate, the water pump 403 sprays the glue in the glue tank 401 onto the tape substrate. When the tape substrate after spraying the glue passes through the scraper 208, the glue that is higher than the designed thickness is scraped off by the scraper 208 and flows into the glue collecting bucket 103 through the glue outlet 102. When the tape substrate with the glue scraped to be uniform passes through the drying mechanism 500, the glue is air-dried, and at this time, the tape substrate becomes a tape. The tape coater with uniform coating has an advanced design, a compact structure, is easy to use, and operates reliably. By setting three guide rollers 204 distributed in a "pin" shape, the tape substrate always fits with the guide rollers 204 when passing through the chassis 100. By integrating the scraper 208 and the guide rollers 204 on the leveling mechanism 200, it is ensured that the scraper 208 and the guide rollers 204 move synchronously, so that the distance between the scraper 208 and the guide rollers 204 remains unchanged all the time, ensuring that the scraper 208 can scrape the glue thickness on the tape substrate to be uniform and improving the operation quality.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
