DETAILED DESCRIPTION

[0026] Example

[0027] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] The specific model specifications need to be selected based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. Figure 1 The coating device shown includes a frame assembly 1, a dimple coating assembly 2 and a slit coating assembly 3 mounted within the frame assembly 1, and a plurality of adjustment roller assemblies 4 disposed on either side of the dimple coating assembly 2 and the slit coating assembly 3. The dimple coating assembly 2 is disposed below the slit coating assembly 3. When different coating liquids need to be applied to a substrate during production, coating can be performed separately on the dimple coating assembly 2 and the slit coating assembly 3 using different film paths.

[0029] like Figure 2As shown, the frame assembly 1 includes a front vertical plate 11, a rear vertical plate 12 and several fixed beams 13 for fixing the front vertical plate 11 and the rear vertical plate 12. The fixed beams 13 can determine the distance between the front vertical plate 11 and the rear vertical plate 12, which facilitates the installation of the micro-concave coating assembly 2 and the slit coating assembly 3.

[0030] like Figure 3 As shown, the micro-concave coating assembly 2 includes a micro-concave roller assembly 21, a micro-concave KISS roller assembly 22 arranged above the micro-concave roller assembly 21, a glue groove lifting mechanism 24 arranged below the micro-concave roller assembly 21, and a scraper assembly 23 arranged on the right side of the micro-concave roller assembly 21. The scraper assembly 23 is separately arranged from the micro-concave roller assembly 21.

[0031] The micro-concave roller assembly 21 includes a micro-concave roller servo motor 211 disposed on the rear vertical plate 12, a number one rotating shaft 212, and a micro-concave roller 213 mounted on the number one rotating shaft 212. The output shaft of the micro-concave roller servo motor 211 is connected to one end of the number one rotating shaft 212, and the other end of the number one rotating shaft 212 is rotationally connected to the front vertical plate 11. The micro-concave roller servo motor 211 can drive the rotation of the number one rotating shaft 212, thereby driving the rotation of the micro-concave roller 213. A coupling is mounted on the outside of the front vertical plate 11, and bearing seats are fixed to the inside of the front vertical plate 11 and the rear vertical plate 12. One end of the number one rotating shaft 212 is rotationally connected to the rear vertical plate 12 via the bearing seat, and the other end is connected to the bearing seat provided on the front vertical plate 11 and passes through the front vertical plate 11. The number one rotating shaft 212 is connected to the micro-concave roller servo motor 211 via a coupling.

[0032] The scraper assembly 23 includes a No. 1 advance / retract cylinder 231 connected to the front vertical plate 11 and the rear vertical plate 12, a scraper body 232 connected to the cylinder head of the No. 1 advance / retract cylinder 231, a pressure-lift cylinder 233 provided on one side of the scraper body 232, a scraper rod 235 hinged to the other side of the scraper body 232, and a scraper 236 connected to one side of the scraper rod 235. The cylinder head of the pressure-lift cylinder 233 is hinged to the scraper body 232, and the cylinder body of the pressure-lift cylinder 233 is hinged to the side of the scraper rod 235 away from the scraper 236. The scraper body 232 is slidably connected to the front vertical plate 11 and the rear vertical plate 12 via a slider 234. The No. 1 advance / retract cylinder 231 can drive the scraper body 232, the pressure-lift cylinder 233, the scraper rod 235, and the scraper 236 to move left and right as a whole.

[0033] The scraper rod 235 is hinged to the scraper body 232 at the middle of the scraper rod 235, forming a lever structure. One end of the scraper rod 235 is connected to a scraper blade 236, and the other end of the scraper rod 235 is hinged to the cylinder body of the pressure-lifting cylinder 233. There is a hole on the side of the scraper rod 235 near the cylinder body of the pressure-lifting cylinder 233, through which a guide rod 237 passes. The bottom end of the guide rod 237 is hinged to the scraper body 232. When the pressure-lifting cylinder 233 is started, the cylinder head of the pressure-lifting cylinder 233 extends to move the cylinder body of the pressure-lifting cylinder 233 upward, thereby causing the side of the scraper rod 235 hinged to the cylinder head of the pressure-lifting cylinder 233 to move upward. At the same time, the scraper blade 236 on the other side of the scraper rod 235 moves downward. The spacing between the scraper blade 236 and the micro-concave roller 213 can be accurately adjusted by the cooperation of the No. 1 advance-retract cylinder 231 and the pressure-lifting cylinder 233. During this process, the guide rod 237 also moves with the scraper rod 235. A stopper is provided at the top of the guide rod 237 to limit the movement of the scraper rod 235. The scraper 236 ensures that the coating liquid is evenly applied to the workpiece, improving the quality of the coating process. Adjusting the distance between the scraper 236 and the dimpled roller 213 can change the thickness of the coating liquid to meet different process requirements.

[0034] The glue trough lifting mechanism 24 includes a glue trough 241 positioned below the dimple roller 213, a rack 242 connected to the bottom of the glue trough 241, a slide 243 connected to the non-toothed side of the rack 242, and a gear 244 connected to the other side of the rack 242. The gear 244 meshes with the rack 242, and the slide 243 is slidably connected to the rear plate 12. When the gear 244 rotates, the rack 242 meshes with the gear 244, causing the glue trough 241 to move up and down. The slide 243, connected to the rack 242, moves up and down within corresponding slide rails on the rear plate 12, limiting the left-right movement of the glue trough lifting mechanism 24 and ensuring smooth up and down movement of the glue trough 241. Adjusting the glue trough 241 up and down allows workers to easily add coating liquid. Adjusting the glue trough 241 up and down also changes the distance between the glue trough 241 and the dimple roller 213, thereby varying the depth of the workpiece immersed in the coating liquid during coating.

[0035] The slightly concave KISS roller assembly 22 includes two KISS roller lifting cylinders 221, one mounted on the front vertical plate 11 and the other on the rear vertical plate 12. The cylinder heads of the KISS roller lifting cylinders 221 are connected to a fixed rod 222, with a scale mounted in the middle. One side of the fixed rod 222 is slidably connected to the rear vertical plate 12. A slide groove is provided on the left side of the fixed rod 222, and a slide bar is provided on the rear vertical plate 12 that matches the slide groove on the fixed rod 222. The slide bar fits into the slide groove on the fixed rod 222 and is slidably connected to the rear vertical plate 12. When the KISS roller lifting cylinders 221 are activated, the fixed rod 222 can move up and down along the slide bar. A fixed platform 226 is fixedly connected to the other side of the fixed rod 222. The fixed platform 226 is rotatably connected to the upper end of the threaded rod 223, so that the threaded rod 223 does not move up and down within the fixed platform 226 during rotation. The lower end of threaded rod 223 is threadedly connected to the upper section of fixed rod 224. Rotation of threaded rod 223 drives fixed rod 224 up and down. The middle section of fixed rod 224 is slidably connected to fixed rod 1 222, and a prominent arrow indicator at the connection point allows for fine adjustment according to the scale. The lower section of fixed rod 223 is rotatably connected to one side of a slightly concave KISS roller 225, which has a similar structure on the other side. Activating the KISS roller lifting cylinders 221 at both ends drives the slightly concave KISS rollers 225 up and down.

[0036] like Figure 4 As shown, the slit coating assembly 3 includes a slit coating roller assembly 31, a slit coating nozzle assembly 32 separately arranged on the right side of the slit coating roller assembly 31, a slit gap adjustment assembly 33 separately arranged above the slit coating roller assembly 31, and a slit negative pressure chamber assembly 34 arranged on the left side of the slit coating nozzle assembly 32.

[0037] The slit coating nozzle assembly 32 includes a No. 2 advance / retract cylinder 321 mounted on the rear vertical plate 12, a coating nozzle body 324 connected to the cylinder head of the No. 2 advance / retract cylinder 321, and a coating nozzle 322 mounted on the top of the coating nozzle body 324. An adjustment screw 323 is connected to the rear of the coating nozzle 322 for fine-tuning the distance between the coating nozzle 322 and the slit coating roller 313. The coating nozzle 322 is slidably connected to the rear vertical plate 12. When the No. 2 advance / retract cylinder 321 is activated, the cylinder head drives the coating nozzle body 324 to move left and right, which can significantly adjust the distance between the coating nozzle 322 and the slit coating roller 313. Turning the screw 323 drives the coating nozzle 322 to slide on the coating nozzle body 324. The adjustment screw 323 can finely adjust the distance between the coating nozzle 322 and the slit coating roller 313, making it easier for the operator to control the coating process of the workpiece. The coating nozzle 322 sprays the coating liquid to coat and dye the workpiece. The thickness of the coating liquid on the workpiece can be changed by adjusting the distance between the coating nozzle 322 and the slit coating roller 313.

[0038] like Figure 5 As shown, the slit coating roller assembly 31 includes a slit roller servo motor 311 arranged on the rear vertical plate 12, a second rotating shaft 312 and a slit coating roller 313 installed on the second rotating shaft 312. The output shaft of the slit roller servo motor 311 is connected to one end of the No. 2 rotating shaft 312, and the other end of the No. 2 rotating shaft 312 is rotationally connected to the front vertical plate 11. When the slit roller servo motor 311 is started, it can drive the No. 2 rotating shaft 312 to rotate, thereby driving the rotation of the slit coating roller 313. A coupling is provided on the outer side of the front vertical plate 11, and bearing seats are provided on the inner side of the rear vertical plate 12 and the inner side of the front vertical plate 11. One end of the No. 2 rotating shaft 312 is rotationally connected to the rear vertical plate 12 through the bearing seat, and the other end is connected to the bearing seat provided on the front vertical plate 11 and passes through the front vertical plate 11. The No. 2 rotating shaft 312 is connected to the slit roller servo motor 311 through a coupling.

[0039] like Figure 6As shown, the slit gap adjustment assembly 33 includes a slit gap servo motor 331 arranged at the top of the frame assembly 1, and the output shaft of the slit gap servo motor 331 is connected to a ball screw 332, and the ball screw 332 is threadedly connected to an inclined block 333 with a threaded hole, and the inclined block 333 is in contact with the coating nozzle body 324 through a roller. Before starting coating, start the slit gap servo motor 331. The output shaft of the slit gap servo motor 331 drives the ball screw 332 to rotate and the inclined block 333 to move. The inclined block 333 has a slight inclination. After adjusting the inclined block 333 to a suitable position, use the No. 2 advance and retreat cylinder 321 to significantly adjust the position of the coating nozzle body 324. The roller provided on the coating nozzle body 324 contacts the inclined block 333. At this time, the set gap between the coating nozzle 322 and the slit coating roller 313 can be achieved. Then, according to the technical requirements of the production workpiece, use the adjusting screw 323 to slightly adjust the distance between the coating nozzle 322 and the slit coating roller 313. If the gap between the coating nozzle 322 and the slit coating roller 313 needs to be adjusted, the slit gap servo motor 331 is used to adjust the ramp 333 before coating begins. Then, based on detailed technical requirements, the adjustment screw 323 is used to slightly adjust the gap between the coating nozzle 322 and the slit coating roller 313. Production can then begin only after the required gap is achieved. This allows for precise control of the gap between the coating nozzle 322 and the slit coating roller 313.

[0040] like Figure 8 As shown, the slit negative pressure chamber assembly 34 includes a negative pressure fan 341, a buffer tank 343 to which the output of negative pressure fan 341 is connected via a pipe, and a negative pressure chamber 344 to which the output of buffer tank 343 is connected. A pipeline valve 342 is provided between the output of negative pressure fan 341 and the input of buffer tank 343. The negative pressure in negative pressure chamber 344 can be controlled by adjusting the speed of negative pressure fan 341 and the opening of pipeline valve 342, and monitored by a differential pressure gauge. By creating a localized low-pressure airflow field, negative pressure chamber 344 ensures uniform distribution of coating material on the surface of the web, preventing paint accumulation or thinning, thereby improving coating uniformity and consistency. It also enables precise control of coating thickness to prevent defects such as bubbles and cracks in the coating.

[0041] like Figure 7As shown, the adjustment roller assembly 4 includes an adjustment roller base 41 mounted on the front and rear vertical plates 11 and 12. A longitudinal threaded rod 42 and a locking screw 43 are mounted on the adjustment roller base 41. The longitudinal threaded rod 42 and the locking screw 43 are connected to one end of the adjustment roller 44, allowing the longitudinal threaded rod 42 to move the adjustment roller 44 up and down. The connection between the adjustment roller base 41, the locking screw 42, and the longitudinal threaded rod 43 is configured as a slot. A threaded slider is slidably connected in the slot. The longitudinal threaded rod 42 and the locking screw 43 are threadedly connected to the slider. To adjust the position of the adjustment roller 44, the longitudinal threaded rod 42 is adjusted by simply attaching an adjustment handle 45 to the longitudinal threaded rod 42 and turning the adjustment handle 45. The longitudinal threaded rod 42 pushes the adjustment roller 44 downward, and the slider connected to the locking screw 43 slides downward within its slot. If the substrate path deviates during production, the adjustment roller assembly 4 can be adjusted to correct the path.

[0042] When in use, the film can be passed through the corresponding sheet path according to the processing requirements of the workpiece to carry out the corresponding processing. If the process needs to be changed, it is only necessary to change the sheet path through which the film is passed.

[0043] Therefore, the utility model adopts a coating device with the above structure, integrating multiple coating units into one device. For coating different coating liquids, any precision coating mode can be used separately. This not only saves site space while meeting production needs, but also reduces equipment costs and simplifies worker operations.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
