[0001] This invention relates to the technical field of automatic zirconium powder coating machines for uniform coating, specifically to an automatic zirconium powder coating machine for uniform coating. Background Technology

[0002] For some workpieces (such as ferrites), zirconium powder needs to be applied to the workpieces on the conveyor belt during the production process to prevent the workpiece surface from sticking. Therefore, a zirconium powder machine is required. After searching, it was found that a typical zirconium powder machine in the prior art is a zirconium powder spreading mechanism published in CN209259045U, which relates to the field of powder spreading equipment technology. The key points of its technical solution are: it includes a frame set on the conveyor belt and a powder storage box set above the conveyor belt. The powder storage box has a powder outlet at the bottom and a powder dispensing device at the powder outlet. The key feature is that: a lifting slide rail is set on the frame, and the sliding direction of the lifting slide rail is perpendicular to the conveying direction of the conveyor belt. The powder storage box is slidably set on the lifting slide rail. A positioning platform is slidably set on the lifting slide rail. The powder storage box is fixed on the positioning platform, and a driving component for driving the positioning platform to slide on the lifting slide rail is set between the frame and the powder storage box. Its main feature is that the positioning table is driven by the drive component to slide on the lifting slide rail, and the height between the powder storage box and the conveyor belt is adjusted to adjust the height of the powder outlet, so as to adapt to different workpieces for powdering and achieve the effect of improving applicability.

[0003] In summary, most existing zirconium powder coating machines add zirconium powder to workpieces by scattering, which easily leads to the dispersion and fall of zirconium powder, resulting in waste of zirconium powder resources and affecting the addition effect. To address these issues, existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic zirconium powder coating machine for uniform application, in order to solve the problem mentioned in the background art that most existing zirconium powder coating machines add zirconium powder to the workpiece by throwing, which easily leads to the phenomenon of zirconium powder being scattered and falling off, resulting in waste of zirconium powder resources and affecting the addition effect of zirconium powder.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic zirconium powder coating machine for uniform coating, comprising a drive wheel and a reduction motor.

[0007] The reduction motor is located on one side of the storage mechanism, and the output end of the reduction motor is connected to the chuck. The reduction motor is also mounted on a mounting frame, which is mounted on the machine frame and has a driven post-processing mechanism.

[0008] Preferably, the conveyor belt is symmetrically provided with limit plates, and the limit plates are all connected to the adjusting rods, while the adjusting rods are rotatably connected to the frame.

[0009] Preferably, the sensing mechanism includes a support frame, a cylinder, a sensor switch, a sensor head, and a lever. The bottom of the support frame is connected to the frame, the cylinder is connected through the support frame, and the sensor switch is provided above the cylinder. One end of the sensor switch is connected to the sensor head, and the sensor head is in contact with the lever.

[0010] Preferably, the paddle is positioned above the conveyor belt and is rotatably connected to the cylinder.

[0011] Preferably, the storage mechanism includes a zirconium powder box, a stepper motor, a fixed frame, a rotating frame, a geared disc, a storage rod, and a feeding hopper. The fixed frame is connected to the top of the zirconium powder box, and a stepper motor is installed on the fixed frame. The output end of the stepper motor is connected to the rotating frame, and the bottom end of the rotating frame is connected to the geared disc. A storage rod is provided on one side of the geared disc, and the storage rod is connected through the bottom of the zirconium powder box. A feeding hopper is provided below the storage rod.

[0012] Preferably, the toothed disc is engaged with the storage rod, and the storage rod is rotatably connected to the bottom of the zirconium powder box, while the zirconium powder box is connected to the feed hopper.

[0013] Preferably, the feed hopper is inclined and positioned above the sponge roller.

[0014] Preferably, the chucks are provided in two sets, and the chucks are connected by a belt drive structure.

[0015] Preferably, the driven post-processing mechanism includes a first rotating rod, a cleaning brush, a second rotating rod, a support plate, a first rotating drum, a hanging plate, a second rotating drum, and a fan blade assembly. The first rotating rod is connected to the second rotating rod via a belt drive structure. The cleaning brush is connected to the top of both the first and second rotating rods and contacts the conveyor belt. Both the first and second rotating rods are connected to the support plate on the inner wall of the mounting frame. The first rotating drum is connected to the rear wall of the support plate and is connected to both the second rotating rod and the second rotating drum via a belt drive structure. The first rotating drum is also connected to a chuck on one side via a gear drive structure. Both the second and first rotating drums are rotatably connected to the hanging plate. A fan blade assembly is connected to the second rotating drum. The fan blade assembly is located on the side of the rotating brush and is positioned above the conveyor belt.

[0016] The method of using the automatic zirconium powder coating machine for uniform coating includes the following steps:

[0017] S1: The geared motor drives the drive roller to rotate, and the drive roller will drive the drive wheel to rotate through the belt transmission structure. The drive wheel drives the driven wheel to rotate together through the conveyor belt, so that the conveyor belt moves the workpiece from left to right.

[0018] S2: During the process of moving the workpiece to the right, it will come into contact with the bottom end of the lever. After being contacted, the bottom end of the lever will rotate. During the rotation, when the top end of the lever comes into contact with the sensing head on the inductive switch, the inductive switch will receive the impact signal and start the external water supply device to drain water onto the sponge roller through the drip pipe to moisten it. At the same time, the inductive switch will start the stepper motor, the second DC motor and the first DC motor simultaneously.

[0019] S3: The stepper motor will drive the gear plate through the rotating frame to push the storage rod to rotate inside the zirconium powder box, so that the storage rod discharges the zirconium powder in the zirconium powder box into the inside of the feed hopper, and then guides it to the sponge roller through the inclined feed hopper. At the same time, since the sponge roller is wetted with water, the zirconium powder will form a paste after falling onto the sponge roller.

[0020] S4: The second DC motor drives the sponge roller to rotate and apply zirconium powder paste to the upper surface of the workpiece that has moved below it. At the same time, the turntable starts to rotate under the drive of the first DC motor, so that the reciprocating rod pushes the moving brush back and forth during the rotation of the turntable. Thus, while the moving brush guides water to the sponge roller, the zirconium powder on the sponge roller is evenly applied by reciprocating movement.

[0021] S5: After being coated by the sponge roller, the workpiece will continue to move to the right under the conveyor belt. At the same time, the reduction motor drives the chuck to rotate. With the cooperation of the belt drive structure, the chuck will drive two sets of rotating brushes to rotate synchronously. The two sets of rotating brushes will successively coat the anti-zirconia powder paste on the top of the workpiece below, so that it is evenly distributed on the workpiece.

[0022] S6: The first rotating drum will rotate with the chuck under the cooperation of the gear transmission structure. At the same time, the first rotating drum will drive the first rotating rod, the second rotating rod and the second rotating drum to rotate together through the belt transmission structure. When the first rotating rod and the second rotating rod rotate, the cleaning brush on their top will rotate to clean the conveyor belt at the bottom of the frame. When the second rotating drum rotates, the fan blade assembly at the bottom will rotate to exhaust air to the workpiece passing over it, thereby facilitating the drying speed of the zircon paste on its top. After being dried by exhaust air, the workpiece will be automatically unloaded by the conveyor belt.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the automatic zirconium powder coating machine that uniformly coats zirconium powder,

[0024] (1) This invention effectively solves the problem that most existing zirconium powder coating machines add zirconium powder to workpieces by throwing, which easily leads to the dispersion and fall of zirconium powder, resulting in waste of zirconium powder resources and affecting the addition effect. The geared motor drives the drive roller to rotate the drive wheel, and the drive wheel will drive the driven wheel to rotate synchronously through the conveyor belt. This causes the conveyor belt to move the workpiece from left to right. During the rightward movement of the workpiece, it will contact and collide with the bottom of the paddle. After being contacted, the paddle will rotate around the cylinder. When its top rotates and contacts the sensing head on the induction switch, the induction switch will control the external water supply equipment to start, and water will be discharged to the sponge roller through the drip pipe to wet it. The stepper motor is controlled to rotate. When the stepper motor rotates, it drives the gear plate through the rotating frame to rotate the storage rod, which discharges the zirconium powder in the zirconium powder box into the hopper, thus achieving uniform and quantitative feeding. This facilitates the uniformity of subsequent coating. The zirconium powder entering the hopper will fall onto the wet sponge roller to form a paste. At the same time, the sponge roller, driven by the second DC motor, will rotate and roll over the top of the product, thus coating the top of the product with a layer of zirconium powder. Compared with the traditional scattering method, this effectively avoids the waste of zirconium powder due to scattering. In addition, the turntable will rotate under the drive of the first DC motor, and the reciprocating rod connected to the turntable will push the moving brush to move during its rotation. This allows water to be diverted to the sponge roller while the zirconium powder on the sponge roller is evenly applied, thus ensuring the uniformity of the coating.

[0025] (2) The present invention can effectively solve the problem that the existing zirconium powder coating machine only has one coating process by using a geared motor, chuck and rotating brush. As a result, the coating process is prone to unevenness due to the short contact time between the coating mechanism and the workpiece. The geared motor drives the chuck to rotate, and the chuck will drive two sets of rotating brushes to rotate synchronously under the cooperation of the belt drive structure. The two sets of rotating brushes will successively rotate and coat the workpiece with zirconium powder on the top below it. That is, by extending the contact time between the coating component and the workpiece and increasing the number of coating components, the uniformity of zirconium powder coating can be further guaranteed.

[0026] (3) The present invention can effectively solve the problem that zirconium powder contaminates the conveyor belt during the brushing process of the existing zirconium powder coating machine by using the combination of the driven post-processing mechanism and the mounting frame. The first drum in the driven post-processing mechanism will rotate together with the chuck on the top of the rotating brush under the cooperation of the gear transmission structure. At the same time, the first drum will drive the first rotating rod, the second rotating rod and the second drum to rotate synchronously under the cooperation of the belt transmission structure. When the first rotating rod and the second rotating rod rotate, the cleaning brush on the top of them will rotate to clean the conveyor belt, thereby achieving the purpose of automatic cleaning, which is more convenient and faster than manual cleaning. When the second drum rotates, the fan blade assembly at the bottom of it will rotate to exhaust air to the workpiece passing over it, thereby facilitating the drying speed of the zircon paste on the top of it. Moisture adheres to the workpiece, thereby improving the adhesion of zirconium powder and enriching the functionality of the device. Attached Figure Description

[0041] In a further embodiment, the storage mechanism 11 includes a zirconium powder box 1101, a stepper motor 1102, a fixed frame 1103, a rotating frame 1104, a geared disc 1105, a storage rod 1106, and a feeding hopper 1107. The top of the zirconium powder box 1101 is connected to the fixed frame 1103, and the stepper motor 1102 is mounted on the fixed frame 1103. The output end of the stepper motor 1102 is connected to the rotating frame 1104, and the bottom end of the rotating frame 1104 is connected to the geared disc 1105.

[0042] In a further embodiment, the toothed disc 1105 is meshed with the storage rod 1106, and the storage rod 1106 is rotatably connected to the bottom of the zirconium powder box 1101.

[0043] In a further embodiment, the feed hopper 1107 is inclined and is positioned above the sponge roller 12.

[0044] The reduction motor 21 is located on one side of the storage mechanism 11, and the output end of the reduction motor 21 is connected to the chuck 22. The reduction motor 21 is mounted on the mounting frame 24, which is mounted on the frame 26. The mounting frame 24 is equipped with a driven post-processing mechanism 25.

9. The automatic zirconium powder coating machine for uniform coating according to claim 8, characterized in that, The method of using the automatic zirconium powder coating machine for uniform coating includes the following steps: S1: The geared motor (3) drives the drive roller (2) to rotate. The drive roller (2) will drive the drive wheel (1) to rotate through the belt transmission structure. The drive wheel (1) drives the driven wheel (5) to rotate together through the conveyor belt (4), so that the conveyor belt (4) drives the workpiece to move from left to right. S2: During the process of moving the workpiece to the right, it will come into contact with the bottom end of the lever (805). After the bottom end of the lever (805) is contacted, it will rotate. During the rotation, when the top end of the lever (805) comes into contact with the sensing head (804) on the inductive switch (803), the inductive switch (803) will turn on the external water supply device when it receives the impact signal and drain water to the sponge roller (12) through the drip pipe (14) to moisten it. At the same time, the inductive switch (803) will start the stepper motor (1102), the second DC motor (20) and the first DC motor (19). S3: The stepper motor (1102) will drive the gear plate (1105) through the rotating frame (1104) to push the storage rod (1106) to rotate inside the zirconium powder box (1101), so that the storage rod (1106) discharges the zirconium powder in the zirconium powder box (1101) into the inside of the feed hopper (1107), and then guides it to the sponge roller (12) through the inclined feed hopper (1107). At the same time, since the sponge roller (12) is wetted with water, the zirconium powder will form a paste after falling onto the sponge roller (12). S4: The second DC motor (20) drives the sponge roller (12) to rotate and apply zirconium powder paste to the upper surface of the workpiece that has moved below it. At the same time, the turntable (18) starts to rotate under the drive of the first DC motor (19), so that the reciprocating rod (17) pushes the moving brush (15) to move back and forth during the rotation of the turntable (18). Thus, while the moving brush (15) guides water to the sponge roller (12), the zirconium powder on the sponge roller (12) is moved back and forth and evenly applied. S5: After being coated by the sponge roller (12), the workpiece will continue to move to the right under the conveying action of the conveyor belt (4). At the same time, the reduction motor (21) drives the chuck (22) to rotate. With the cooperation of the belt drive structure, the chuck (22) will simultaneously drive two sets of rotating brushes (23) to rotate synchronously. The two sets of rotating brushes (23) will successively rotate and coat the zirconium powder paste on the top of the workpiece below it, so that it is evenly distributed on the workpiece. S6: The first rotating drum (2505) will rotate with the chuck (22) under the cooperation of the gear transmission structure. At the same time, the first rotating drum (2505) will drive the first rotating rod (2501), the second rotating rod (2503) and the second rotating drum (2507) to rotate together through the belt transmission structure. When the first rotating rod (2501) and the second rotating rod (2503) rotate, the cleaning brush (2502) on the top of them will rotate to clean the conveyor belt (4) at the bottom of the frame (26). When the second rotating drum (2507) rotates, the fan blade assembly (2508) at the bottom of it will rotate to exhaust air to the workpiece passing under its bottom, so as to speed up the drying speed of the zirconium powder paste on its top. After being dried by exhaust, the workpiece will be automatically unloaded under the conveying action of the conveyor belt (4).
