Description

Technical Field

[0001] This application relates to the technical field of coating equipment, and in particular to an automated coating machine for workpieces in a medium-frequency induction heating furnace. Background Technology

[0002] The automated coating machine for medium-frequency induction heating furnace workpieces is a specialized device used to automatically coat workpieces with anti-adhesion coatings before processing in the medium-frequency induction heating furnace. By uniformly coating with a mud-based anti-adhesion coating, an isolation layer is formed to prevent the workpieces from sticking together due to high temperatures during processing in the medium-frequency induction heating furnace. Currently, existing anti-adhesion coating equipment for medium-frequency induction heating furnaces typically includes a feeding platform, a coating tank, a manual coating tool, and a workpiece support frame. During use, the operator moves the workpiece to be placed into the medium-frequency induction heating furnace onto the workpiece support frame, manually adjusts the support frame to fix the workpiece, takes out the coating from the coating tank, and manually coats the workpiece surface according to its shape and size using the hand-held coating tool. After completion, the operator transfers the workpiece to the feeding end of the medium-frequency induction heating furnace. When using existing anti-adhesion coating equipment for medium-frequency induction heating furnaces, operators need to manually complete the handling, fixing, and coating operations of the workpieces. Manual operation is prone to uneven coating and inconsistent thickness of the anti-adhesion coating, causing local adhesion of the workpieces during processing in the medium-frequency induction heating furnace, affecting the processing quality and subsequent processing. Summary of the Invention

[0003] To prevent workpieces from sticking together during processing in a medium-frequency induction heating furnace, this application provides an automated coating machine for workpieces in a medium-frequency induction heating furnace.

[0004] This application provides an automated coating machine for workpieces in a medium-frequency induction heating furnace, which adopts the following technical solution: An automated coating machine for workpieces in a medium-frequency induction heating furnace includes a base, a mounting base, a feeding assembly, a coating assembly, and the medium-frequency induction heating furnace. The base is horizontally positioned, and a mounting frame is mounted on the base. A first guide wheel and a second guide wheel are rotatably connected to the mounting frame, with the second guide wheel positioned above the first guide wheel. Multiple mounting frames, first guide wheels, and second guide wheels are spaced apart along the length of the base. A push rod is horizontally positioned between the first and second guide wheels. A pusher telescopic rod is mounted on one side of the base, with its movable end fixedly connected to one end of the push rod. A placement frame is fixedly connected to the side of the base away from the pusher telescopic rod. The mounting base is located on one side of the base. The feeding assembly is located on the mounting base and is used to push workpieces from the mounting base onto the placement frame. The coating assembly is located on the placement frame and is used to apply an anti-adhesion coating to the surface of the workpieces on the placement frame. The medium-frequency induction heating furnace is located on the side of the placement frame away from the base.

[0005] By adopting the above technical solution, during use, the feeding component pushes the workpiece on the mounting base onto the placement rack, and the coating component applies an anti-adhesion coating to the surface of the workpiece on the placement rack. After the anti-adhesion coating is applied to the surface of the workpiece, the operator drives the movable end of the pusher extension rod to extend. The movable end of the pusher extension rod drives the push rod to move towards the medium-frequency induction heating furnace. The push rod pushes the coated workpiece into the medium-frequency induction heating furnace. The anti-adhesion coating forms an isolation layer, making it difficult for the workpiece to stick during processing in the medium-frequency induction heating furnace.

[0006] Optionally, a guide plate is fixedly connected to one side of the mounting base, and the end of the guide plate away from the mounting base is fixedly connected to the placement frame; the feeding assembly includes a feeding part and a pushing part; the feeding part is located on the mounting base and is used to move the workpiece close to the guide plate; the pushing part is located on the mounting base and is used to push the workpiece close to the guide plate onto the placement frame.

[0007] By adopting the above technical solution, when in use, the operator places the workpiece to be processed on the mounting base, the feeding part moves the workpiece close to the guide plate, and the pushing part pushes the workpiece along the guide plate to the placement rack, realizing the orderly transfer of workpieces, reducing manual handling, and making it easy for workpieces to be moved from the mounting base to the placement rack.

[0009] By adopting the above technical solution, when in use, the first motor works, and the output shaft drives the first sprocket to rotate. The first sprocket drives the second sprocket to rotate synchronously through the chain conveyor belt. The chain conveyor belt moves the workpiece towards the guide plate, making it easy for the workpiece to move to a position close to the guide plate.

[0010] Optionally, the pushing part includes a drive cylinder, a controller, a pushing plate, a mounting plate, a first baffle, and a second baffle; the drive cylinder is horizontally mounted on the mounting base; the controller is mounted on the mounting base and electrically connected to the drive cylinder; the pushing plate is vertically arranged and fixedly connected to the movable end of the drive cylinder; the mounting plate is fixedly arranged at the top of the pushing plate, and an infrared detector is mounted on the mounting plate, the infrared detector being electrically connected to the controller; the first baffle is vertically arranged on the side of the pushing plate away from the drive cylinder and fixedly connected to the pushing plate; the second baffle is vertically arranged on the side of the pushing plate close to the drive cylinder and fixedly connected to the pushing plate.

[0011] By adopting the above technical solution, when the chain conveyor belt moves the workpiece close to the guide plate, the workpiece abuts against the first baffle. The infrared detector detects that the workpiece has moved close to the guide plate and sends the detection signal to the controller. The controller drives the moving end of the drive cylinder to extend. The moving end of the drive cylinder drives the pusher plate to move closer to the guide plate. The pusher plate pushes the workpiece to slide along the guide plate onto the placement rack. The second baffle blocks subsequent workpieces, preventing multiple workpieces from being pushed at the same time, making it easier to push a single workpiece onto the placement rack.

[0012] Optionally, the coating assembly includes a coating bucket, a stirring unit, and a coating section; the coating bucket is located above the placement rack, a support frame is fixedly mounted on the coating bucket, a feed pipe is connected to the top of the coating bucket, and a water inlet is provided at the top of the coating bucket; the stirring unit is located on the coating bucket and is used to stir the anti-stick coating inside the coating bucket; the coating section is located below the coating bucket and is used to apply the anti-stick coating to the surface of the workpiece on the placement rack; the placement rack has flow holes, and a collection box is fixedly mounted on the base, the collection box is located below the placement rack, and its top is open.

[0013] By adopting the above technical solution, the feed pipe is used to add anti-blocking coating to the coating bucket, the stirring part stirs the coating to prevent the coating from settling and clumping, the coating part applies the coating to the surface of the workpiece, and the flow hole on the placement rack allows excess coating to flow into the collection box, realizing the recycling of coating and making the coating more uniform.

[0015] By adopting the above technical solution, during use, the controller controls the second motor to work intermittently. The output shaft of the second motor drives the drive rod to rotate, and the drive rod drives the stirring plate to rotate in the paint bucket. The stirring plate stirs the anti-blocking paint, making the paint composition uniform and avoiding poor coating effect due to sedimentation.

[0016] Optionally, the stirring unit further includes a baffle and a water bucket; the baffle is horizontally disposed inside the paint bucket and fixedly connected to the drive rod, and a connecting hole is provided on the baffle, which is connected to the water inlet; the water bucket is vertically disposed at the top of the paint bucket, and a water outlet is provided at the bottom, which is connected to the water inlet.

[0017] By adopting the above technical solution, when in use, the drive rod drives the baffle to rotate. When the connecting hole on the baffle is aligned with the water inlet, the water in the bucket enters the paint bucket through the water outlet, water inlet and connecting hole. When the connecting hole and water inlet are misaligned, the water in the bucket does not easily flow into the paint bucket, making it easy for the operator to control the paint concentration by stirring frequency.

[0018] Optionally, the coating unit includes a discharge pipe, a connecting hose, a discharge nozzle, a multi-stage electric telescopic rod, and a coating brush; a guide plate is vertically arranged on the guide plate, the guide plate is slidably connected to the guide plate, and a connecting block is fixedly connected to the side of the guide plate near the placement frame; the discharge pipe is located at the bottom of the coating bucket and communicates with the coating bucket; the connecting hose is located below the coating bucket, and one end is connected to the discharge pipe; the discharge nozzle is located below the coating bucket and communicates with the connecting hose, and the discharge nozzle is fixedly connected to the connecting block; the fixed end of the multi-stage electric telescopic rod is fixedly arranged on the discharge nozzle and electrically connected to the controller; the coating brush is horizontally arranged and fixedly connected to the movable end of the multi-stage electric telescopic rod; a reset plate is fixedly connected to one side of the push rod.

[0019] By adopting the above technical solution, when the pusher plate pushes the workpiece to slide along the guide plate to the placement rack, the workpiece squeezes the guide plate, and the guide plate slides away from the medium-frequency induction heating furnace. The connecting block on the guide plate drives the discharge nozzle to move synchronously. The paint in the paint bucket is sprayed from the discharge nozzle to the surface of the workpiece through the discharge pipe and connecting hose. The movable end of the multi-stage electric telescopic rod extends and retracts, driving the paint brush to move on the surface of the workpiece and evenly apply the paint. After the anti-adhesion paint is applied to the surface of the workpiece, the operator drives the pusher rod to move towards the medium-frequency induction heating furnace through the pusher telescopic rod. The pusher rod pushes the coated workpiece into the medium-frequency induction heating furnace. The reset plate on the pusher rod drives the guide plate to reset, making the equipment easy to reuse.

[0020] Optionally, a drive telescopic rod is horizontally arranged on the placement rack. The fixed end of the drive telescopic rod is fixedly connected to the placement rack, and the rodless cavity is filled with liquid. A spring is horizontally arranged in the rodless cavity of the drive telescopic rod, and the two ends of the spring are fixedly connected to the movable end and the fixed end of the drive telescopic rod, respectively. An isolation telescopic plate is horizontally arranged at the bottom of the paint bucket. The fixed end of the isolation telescopic plate is fixedly connected to the paint bucket, and the movable end is inserted into the discharge pipe. The movable end of the isolation telescopic plate is used to isolate the discharge pipe, and the plate cavity is filled with liquid. The plate cavity of the isolation telescopic plate is connected to the rodless cavity of the drive telescopic rod through a pipe.

[0021] By adopting the above technical solution, when the pusher plate pushes the workpiece to slide along the guide plate to the placement frame, the workpiece squeezes the movable end of the drive telescopic rod, causing the movable end of the drive telescopic rod to retract. The volume of the rodless cavity of the drive telescopic rod decreases, and the liquid in the rodless cavity of the drive telescopic rod flows through the pipe to the plate cavity of the isolation telescopic plate. The volume of the plate cavity of the isolation telescopic plate increases, the movable end of the isolation telescopic plate retracts, and the movable end of the isolation telescopic plate is disconnected from the discharge pipe, making it easier for the anti-sticking paint in the paint bucket to flow onto the paint brush.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a feeding assembly, the workpiece can be easily moved onto the placement rack; 2. By setting up a coating component, the workpiece can be easily coated automatically.

[0038] During use, the operator adds anti-adhesion coating to the coating bucket 41 through the feed pipe 412. The controller 322 controls the second motor 421 to work intermittently. The output shaft of the second motor 421 drives the drive rod 422 to rotate, which in turn drives the stirring plate 423 to rotate inside the coating bucket 41, thus stirring the anti-adhesion coating. When the equipment is used for a long time, the operator fills the water bucket 425 with water. When the controller 322 controls the second motor 421 to drive the drive rod 422, the drive rod 422 drives the baffle 424 to rotate. When the connecting hole 4241 is aligned with the water inlet 413, the water in the water bucket 425 enters the coating bucket 41 through the water outlet 4251, the water inlet 413, and the connecting hole 4241. When the connecting hole 4241 is misaligned with the water inlet 413, the water in the water bucket 425 does not easily flow into the coating bucket 41.

[0039] When the pusher plate 323 pushes the workpiece toward the placement rack 14, the workpiece squeezes the guide plate 211, and the guide plate 211 slides away from the medium frequency induction heating furnace 5. The connecting block 2111 on the guide plate 211 drives the discharge nozzle 433 to move synchronously, and the discharge nozzle 433 moves to one side of the workpiece. When the workpiece slides onto the placement rack 14, the workpiece presses against the movable end of the drive telescopic rod 142, causing the movable end of the drive telescopic rod 142 to retract. The volume of the rodless cavity of the drive telescopic rod 142 decreases, and the liquid in the rodless cavity of the drive telescopic rod 142 flows through the pipe into the plate cavity of the isolation telescopic plate 414. The volume of the plate cavity of the isolation telescopic plate 414 increases, and the movable end of the isolation telescopic plate 414 retracts. The movable end of the isolation telescopic plate 414 disengages from the discharge pipe 431, and the paint in the paint bucket 41 is sprayed from the discharge nozzle 433 onto the surface of the workpiece through the discharge pipe 431 and the connecting hose 432. The movable end of the multi-stage electric telescopic rod 434 extends and retracts, driving the paint brush 435 to move on the surface of the workpiece and evenly apply the paint.

[0040] The implementation principle of an automated coating machine for workpieces in a medium-frequency induction heating furnace according to an embodiment of this application is as follows: During use, the operator adds anti-adhesion coating to the coating bucket 41 through the feed pipe 412. The controller 322 controls the second motor 421 to work intermittently. The output shaft of the second motor 421 drives the drive rod 422 to rotate, which in turn drives the stirring plate 423 to rotate inside the coating bucket 41, thus stirring the anti-adhesion coating. When the equipment is used for a long time, the operator fills the water bucket 425 with water. When the controller 322 controls the second motor 421 to drive the drive rod 422, the drive rod 422 drives the baffle 424 to rotate. When the connecting hole 4241 is aligned with the water inlet 413, the water in the water bucket 425 enters the coating bucket 41 through the water outlet 4251, the water inlet 413, and the connecting hole 4241. When the connecting hole 4241 is misaligned with the water inlet 413, the water in the water bucket 425 does not easily flow into the coating bucket 41.

[0041] When processing a workpiece, the operator places the workpiece onto the mounting base 2. The operator drives the first motor 311 via the controller 322, and the output shaft drives the first sprocket 312 to rotate. The first sprocket 312 drives the second sprocket 313 to rotate synchronously via the chain conveyor belt 314. The chain conveyor belt 314 moves the workpiece towards the guide plate 21. When the workpiece comes into contact with the first baffle 325, the infrared detector 3241 detects the workpiece and sends a detection signal to the controller 322. The controller 322 drives the movable end of the drive cylinder 321 to extend. The movable end of the drive cylinder 321 drives the pusher plate 323 to move towards the guide plate 21. The pusher plate 323 pushes the workpiece to slide along the guide plate 21 onto the placement rack 14. The second baffle 326 blocks subsequent workpieces.

[0042] When the pusher plate 323 pushes the workpiece toward the placement rack 14, the workpiece presses against the guide plate 211. The guide plate 211 slides away from the medium-frequency induction heating furnace 5. The connecting block 2111 on the guide plate 211 drives the discharge nozzle 433 to move synchronously, and the discharge nozzle 433 moves to one side of the workpiece. When the workpiece slides to the placement rack 14, the workpiece presses against the movable end of the drive telescopic rod 142, causing the movable end of the drive telescopic rod 142 to retract. The liquid in the rodless chamber of the drive telescopic rod 142 flows through the pipe into the plate-containing chamber of the isolation telescopic plate 414. The movable end of the isolation telescopic plate 414 retracts, and the movable end of the isolation telescopic plate 414 disengages from the discharge pipe 431. The paint in the paint bucket 41 is sprayed from the discharge nozzle 433 onto the surface of the workpiece through the discharge pipe 431 and the connecting hose 432. The movable end of the multi-stage electric telescopic rod 434 extends and retracts, driving the paint brush 435 to move on the surface of the workpiece and evenly apply the paint.

[0043] After the anti-adhesion coating is applied to the surface of the workpiece, the operator drives the push rod 12 to move closer to the medium-frequency induction heating furnace 5 by pushing the push rod 13. The push rod 12 pushes the coated workpiece into the medium-frequency induction heating furnace 5. The reset plate 121 on the push rod 12 drives the guide plate 211 to reset, making the equipment easy to reuse.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
