Description

Technical Field

[0001] This invention relates to the field of coating machine technology, and more particularly to an automated coating machine. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint or ink with specific functions, and then dries and rewinds it. It adopts a special multi-functional coating head, which can realize various forms of surface coating. The unwinding and rewinding of the coating machine are equipped with a full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control.

[0003] There are two coating methods: one is to apply photosensitive emulsion to the screen through multiple wet-on-wet operations; the other is to add a drying process after each coating. The third method is to apply a quantitative amount of liquid (or melt) polymer materials such as adhesives or coatings to the surface of the material. It is suitable for the production of flexible substrates such as PVC / PE films. Simply put, it is to apply glue to the film. Specifically, it includes glue application, drying, winding and tension control.

[0004] For example, the utility model patent with publication number CN216368694U, entitled "A Coating Method for Maintaining a Smooth Film Surface," and authorization announcement date of April 26, 2022, includes a machine body. A mounting frame extending into the inner side of the machine body is slidably connected to the bottom of the machine body. A conveyor belt is drivenly connected to one side of the mounting frame. A mounting plate is fixedly connected to the inner side of the machine body. Two leveling shafts are rotatably connected inside the mounting plate. A material box extending above the conveyor belt is fixedly connected to the top wall of the inner cavity of the machine body. A brush is fixedly connected to the bottom of the material box. A scraping device is fixedly connected to the outer side of the material box's outlet end. A vibration device is fixedly connected to the right side of the material box. This patent solves the problem of relying on scrapers or rollers to level coatings by using extrusion rollers to level the film. However, this method has a simple structure and poor leveling effect. If there is dust or unevenness on the film surface, it can easily cause unevenness in the surface coating.

[0005] The shortcomings of existing technologies, including the aforementioned patents, are that since the scraping method and other processes will come into contact with the film surface, the film surface will inevitably be damaged during the contact process, which will easily cause unevenness of the surface coating. Alternatively, if the film is transported by multiple rollers, the film will be subjected to force during the rotation of the rollers, which will cause ripples parallel to the direction of film movement. After the ripples are squeezed with the coating, they will likely cause unevenness of the film surface. Summary of the Invention

[0006] The purpose of this invention is to provide an automated coating machine. In this invention, the smoothing component performs a continuous smoothing action on the film during the reciprocating motion of the gas smoothing mechanism, thereby improving the continuous smoothing of the film during the movement and avoiding the impact of film wrinkles on the product forming effect during the co-extrusion of the film and coating.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Reference Figure 1-12An automated coating machine includes a frame and an extrusion roller 1 mounted on the frame. It also includes two gas smoothing mechanisms 2 symmetrically mounted on the frame, each with a gas inlet. The gas smoothing mechanisms 2 have a first smoothing stroke and a second smoothing stroke. During the first smoothing stroke, the two gas smoothing mechanisms 2 move away from each other, and the gas inlets draw air towards the center of the film on the extrusion roller 1. During the second smoothing stroke, the two gas smoothing mechanisms 2 move relative to each other, and the gas inlets blow air towards the outer side of the film on the extrusion roller 1. The gas smoothing mechanisms 2 reciprocate via a moving component 27 to switch between the first and second smoothing strokes. The gas smoothing mechanism 2 includes a nozzle 51 with a gas flow port connected inside it. It also includes a guide shroud 53 fixed inside the nozzle 51, with a movable sleeve 54 movably fitted on the guide shroud 53. A connecting pipe 62 is fixedly connected to the movable sleeve 54, and an air intake channel and an air exhaust channel are formed on the connecting pipe 62. The air intake channel and the air exhaust channel are respectively connected to two connecting holes 543 opened on the movable sleeve 54. A switching groove 532 adapted to the air intake channel and the air exhaust channel is connected to the guide shroud 53. It also includes a fixed baffle 210. During the stroke switching of the gas smoothing mechanism 2, the nozzle 51 abuts against the baffle 210 to drive the nozzle 51 to rotate passively, so that the switching groove 532 can selectively connect to the air intake channel and the air exhaust channel. Specifically, a gas smoothing mechanism 2 is fixedly connected to the extrusion roller 1 via a frame. A smoothing component 5 is located at the bottom of the gas smoothing mechanism 2. The smoothing component 5 is connected to a pneumatic assembly 6 fixed to the gas smoothing mechanism 2. The pneumatic assembly 6 includes an exhaust pump 61, which is an integrated pump body for both extraction and exhaust. The exhaust pump 61 is connected to the smoothing component 5 via a connecting pipe 62. The connecting pipe 62 has an intake channel and an exhaust channel on its inner side, and these channels are respectively connected to the exhaust port and intake port of the exhaust pump 61. When the smoothing component 5 moves laterally towards the film via the gas smoothing mechanism 2, the exhaust pump 61 generates suction by connecting to the smoothing component 5 through the intake channel of the connecting pipe 62. This suction smooths the film surface during the lateral movement of the smoothing component 5. The smoothing component 5 moves towards the gas... At the end of the smoothing mechanism 2, the smoothing component 5 is fixed to the fixed frame 29. The baffles 210 are fixedly connected to both ends of the fixed frame 29 and come into contact with the smoothing component 5. This causes the smoothing component 5 to passively switch angles after contacting the baffles 210. At the same time, the smoothing component 5 switches from the suction channel in the connecting pipe 62 to the exhaust channel, realizing that the gas flow port of the smoothing component 5 changes from suction to blowing. Then, the gas smoothing mechanism 2 drives the smoothing component 5 to perform a reset movement, realizing that the smoothing component 5 performs a continuous smoothing action on the film during the reciprocating motion of the gas smoothing mechanism 2. This improves the continuous smoothing of the film during the movement and avoids the product molding effect caused by the film wrinkling during the co-extrusion of the film and coating. This makes the smoothing film and coating contact smoother. The device has a simple structure, is flexible in use, and is worth widespread promotion.

[0044] The gas smoothing mechanism 2 includes a guide frame 21, which is distributed in a V-shape above the film. A guide rod 22 is fixedly connected to the inner side of the guide frame 21, and the guide rod 22 is used for the directional movement of the moving component 27. A sleeve wheel 24 is provided at the top of the moving component 27, and a transmission chain 25 is sleeved on the outer side of the sleeve wheel 24. A limiting lever 26 sleeved on the outer side of the transmission chain 25 is in contact with the moving component 27 so that the transmission chain 25 drives the moving component 27 to reciprocate along the guide frame 21. Specifically, in the gas smoothing mechanism 2, the guide frame 21 has a rectangular frame structure. A rectangular strip-shaped guide rod 22 is fixedly connected to the guide frame 21. A moving component 27 is slidably connected to the guide rod 22. A drive shaft 23 is located at the top of the moving component 27. A sleeve wheel 24 is fixedly connected to the bottom of the drive shaft 23. The top of the drive shaft 23 is powered by the driver 4, which facilitates the driver 4 to drive the meshing drive shaft 23 in the gas smoothing mechanism 2 to rotate. The sleeve wheel 24 fixedly connected to the bottom of the drive shaft 23 is fitted with a transmission sleeve. The drive chain 25 has a driven wheel 28 sleeved at one end away from the bushing wheel 24, which causes the limit lever 26 fixedly connected to the drive chain 25 to drive the moving component 27 to move. The smoothing component 5 connected to the bottom of the moving component 27 moves synchronously under the drive of the drive chain 25, so that the smoothing component 5 can reciprocate under the drive of the gas smoothing mechanism 2, which facilitates the smoothing component 5 to smooth the film surface, improves the continuity of the smoothing of the device, and improves the smoothing effect of the film. The device has a simple structure and is flexible in use, and is worth promoting widely.

[0045] The moving component 27 includes a moving block 271. A limiting baffle 272 is fixedly connected to the top of the moving block 271 at an offset position. A limiting groove 273 is opened on the inner side of the moving block 271, and the limiting groove 273 is adapted to the guide rod 22. A connecting rod 274 is fixedly connected to the bottom of the moving block 271. A ratchet shaft 275 is provided at the bottom of the connecting rod 274, and a smoothing component 5 is rotatably connected to one end of the ratchet shaft 275. Specifically, in the moving component 27, the moving block 271 is sleeved on the guide rod 22 through the limiting groove 273. The limiting baffle 272 is fixedly connected to the top of the moving block 271 at an offset position. When the limiting baffle 272 is driven by the limiting lever 26 fixedly connected to the outside of the transmission chain 25, the moving component 27 moves back and forth along the guide rod 22 fixedly connected in the guide rail frame 21. The connecting rod 274 fixedly connected to the bottom of the moving block 271 is connected to a ratchet shaft 275, so that the ratchet shaft 275 is limited after the smoothing part 5 is switched, so as to prevent the smoothing part 5 from shifting during the movement and improve the stability of the smoothing part 5 during the movement. This device has a simple structure and strong practicality.

[0046] The smoothing component 5 includes an air nozzle 51, a flow divider 52 is fixedly connected to the inner side of the air nozzle 51, and a flow guide 53 is sleeved on the outer side of the flow divider 52. The flow divider 52 divides the flow guide 53 into an air inlet chamber and an air outlet chamber, so that during the switching of the air nozzle 51, the connecting pipe 62 fixedly connected to the top of the movable sleeve 54 switches between the air inlet chamber and the air outlet chamber. Specifically, the air nozzle 51 in the smoothing component 5 has an elliptical structure. A flow divider block 52 is fixedly connected to the inner side of the air nozzle 51, and a flow guide shroud 53 is sleeved on the outer side of the flow divider block 52. The flow divider block 52 divides the flow guide shroud 53 into an air inlet chamber and an air outlet chamber. A movable sleeve 54 is sleeved on the outer side of the flow guide shroud 53. The movable sleeve 54 includes a movable plate 541 for fixing. Sealing rings 542 are fixedly connected to both ends of the movable plate 541. The sealing rings 542 are adapted to the switching grooves 532 opened on the arc plate 531. When the air nozzle 51 rotates along the ratchet shaft 275, the connecting hole 543 opened on the sealing ring 542 is adapted to the switching grooves 532 opened on the arc plate 531. This allows the suction and blowing forces in the air nozzle 51 to switch when the air nozzle 51 is passively switched by the baffle 210 during the movement, improving the convenience of using the air nozzle 51. This device has a simple structure and is flexible in use.

[0047] It also includes an edge smoothing mechanism 3, which is located between the gas smoothing mechanism 2 and the extrusion roller 1. The edge smoothing mechanism 3 includes a mounting frame 31, and a suction nozzle assembly 32 is symmetrically slidably arranged inside the mounting frame 31. The suction nozzle assembly 32 moves along the mounting frame 31 to both ends through a transmission assembly 34 to continuously smooth the film during the movement of the suction nozzle assembly 32 to a stop. The suction nozzle assembly 32 includes a suction nozzle block 3221, and an inner cavity groove 3222 is formed inside the suction nozzle block 3221, which communicates with the connecting nozzle 323. A through slot hole 3224 is formed at the bottom end of the suction nozzle block 3221. Limiting blocks 3223 are symmetrically fixedly connected to both ends of the suction nozzle block 3221, and the limiting blocks 3223 are adapted to the mounting frame 31. The mounting frame 31 includes a limiting frame 311, with support plates 313 symmetrically fixedly connected to both ends of the limiting frame 311. A support roller 314 is rotatably connected to one end of the support plate 313 and is located at the bottom of the film. Guide rollers 312 are symmetrically rotatably connected to both ends of the limiting frame 311 and are located on the film. The suction nozzle assembly 32 includes a movable plate 321, with connecting nozzles 323 fixedly connected in an array at the top of the movable plate 321. The bottom end of the connecting nozzle 323 passes through the movable plate 321 and is connected to a suction nozzle component 322. There is a gap between the suction nozzle component 322 and the film. A stop block 324 is fixedly connected to the top of the movable plate 321 and is adapted to the clamping assembly 33 provided on the limiting frame 311. The clamping assembly 33 includes a support base 331, with a crossbar 332 movably connected to the top of the support base 331. A fixing block 333 is fixedly connected to one end of the crossbar 332, and the fixing block 333 is adapted to the abutment block 324. An abutment wheel 335 is rotatably mounted on the other end of the crossbar 332, and the abutment wheel 335 is located above the film and directly above the support roller 314. The transmission assembly 34 includes a guide rail 341, which is fixed to the guide rail frame 21. A lever 342 is slidably connected to the guide rail 341. A pull rope 344 is fixedly connected to one end of the lever 342, and the end of the pull rope 344 away from the lever 342 is fixed to the nozzle assembly 32.Specifically, the mounting bracket 31 in the edge smoothing mechanism 3 has a rectangular structure. A groove is provided on the inner side of the mounting bracket 31, and a suction nozzle assembly 32 is movably connected in the groove. One end of the pull rope 344 in the transmission assembly 34 is fixed to the lever 342. The lever 342 is a triangular structure composed of a sliding rod 3241 and a limiting strip 3242. When the moving assembly 27 in the gas smoothing mechanism 2 moves, it presses against the lever 342 and moves directionally along the guide rail 341. The pull rope 344... The gas smoothing mechanism 2 is guided and limited by the fixed limiting wheel 343 and guide wheel frame 345, causing the pull rope 344 to be driven by force to move the suction nozzle assembly 32 in the mounting frame 31 to both ends. The suction nozzle assembly 32 is connected to the air inlet of the exhaust pump 61 through the conduit, so that the suction nozzle 322 in the suction nozzle assembly 32 is connected to the exhaust pump 61 through the connecting nozzle 323. When the exhaust pump 61 is working, suction is generated in the inner cavity groove 3222 inside the suction nozzle block 3221. The cavity 3222 communicates with the through hole 3224 at the bottom of the suction block 3221, so that the suction assembly 32 can flatten the film on the extrusion roller 1 during the movement of the suction assembly 32 along the mounting frame 31. When the suction assembly 32 contacts the clamping assembly 33, the fixing block 333 fixedly connected to the crossbar 332 in the clamping assembly 33 is in close contact with the abutment block 324 fixedly connected to the movable plate 321, so that the abutment block 324 supports the crossbar 332 to move along the support base 331. The abutment wheel 335 rotatably connected to one end of the crossbar 332 clamps the flattened film on the support roller 314. The tension spring 334 fixedly connected to the other end of the crossbar 332 is used to reset the crossbar 332 after the abutment block 324 separates from the fixing block 333. This allows the film on the extrusion roller 1 to be directly co-extruded with the coating after being flattened, which greatly reduces the product yield caused by wrinkles in the film during the extrusion process with the coating. This device has a simple structure, is flexible in use, and is worth promoting widely.

[0048] Working principle: A gas smoothing mechanism 2 is fixedly connected to the extrusion roller 1 via a frame. The smoothing component 5 is connected to a pneumatic assembly 6 fixed on the gas smoothing mechanism 2. The pneumatic assembly 6 includes an exhaust pump 61, which is an integrated pump body for both extraction and exhaust. When the smoothing component 5 moves laterally toward the film via the gas smoothing mechanism 2, the exhaust pump 61 generates suction through a connecting pipe 62 connected to the smoothing component 5. This suction smooths the film during the lateral movement of the smoothing component 5. When the smoothing component 5 moves to the end of the gas smoothing mechanism 2, baffles 210 are fixedly connected to both ends of the fixing frame 29 and come into contact with the smoothing component 5. This causes the smoothing component 5 to passively switch angles after contacting the baffles 210. Simultaneously, the smoothing component 5 switches from suction to blowing force, and then the gas smoothing mechanism 2 drives the smoothing component 5 to perform a reset movement, realizing that the smoothing component 5 continuously smooths the film during the reciprocating motion of the gas smoothing mechanism 2, improving the continuous smoothing of the film during the movement; secondly, the edge smoothing mechanism 3 located at the tail end of the gas smoothing mechanism 2 has a suction nozzle assembly 32 movably connected to the inner side of its mounting frame 31. One end of the pull rope 344 in the transmission assembly 34 is fixed to the lever 342. The lever 342 is a triangular structure composed of a slide rod 3241 and a limiting strip 3242. When the moving component 27 in the gas smoothing mechanism 2 moves, it abuts against the lever 342. The pull rope 344 moves directionally along the guide rail 341. It is guided and limited by the limiting wheel 343 and guide wheel frame 345 fixed in the gas smoothing mechanism 2, causing the pull rope 344 to be stressed and drive the suction nozzle assembly 32 in the mounting frame 31 to move towards both ends. The suction nozzle assembly 32 connects to the air inlet of the exhaust pump 61 through a conduit, allowing the suction nozzle 322 in the suction nozzle assembly 32 to connect to the exhaust pump 61 through a connecting nozzle 323. When the exhaust pump 61 operates, suction is generated in the inner cavity groove 3222 inside the suction nozzle block 3221. The inner cavity groove 3222 communicates with the through hole 3224 at the bottom of the suction nozzle block 3221, allowing the suction nozzle assembly 32 to move along the mounting frame. During the movement of 31, the film on the extrusion roller 1 is flattened. When the suction nozzle assembly 32 contacts the clamping assembly 33, the fixing block 333, which is fixedly connected to the crossbar 332 in the clamping assembly 33, is in close contact with the abutment block 324, which is fixedly connected to the movable plate 321. This allows the abutment block 324 to support the crossbar 332 to move along the support base 331. The abutment wheel 335, which is rotatably connected to one end of the crossbar 332, clamps the flattened film on the support roller 314. The tension spring 334, which is fixedly connected to the other end of the crossbar 332, is used to reset the crossbar 332 after the abutment block 324 separates from the fixing block 333. This allows the film on the extrusion roller 1 to be directly co-extruded with the coating after being flattened.
