Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically to a scratch-resistant coating equipment for cosmetic bottles. Background Technology

[0002] The background technology of anti-scratch coating equipment for cosmetic bottles mainly stems from the urgent needs of the cosmetic packaging industry for durable appearance, improved texture, and maintenance of brand value. Cosmetic bottles often serve as carriers of brand image, and their surface gloss, color, and feel directly affect the consumer experience. Frequent transportation, use, and cleaning can easily lead to scratches and wear, making the product look old and affecting its high-end positioning. Environmental protection and regulatory requirements necessitate that traditional spraying processes may use coatings containing volatile organic compounds, and coating technology needs to transform towards low-pollution, high-solids-content, or water-based coatings. Balancing cost and efficiency, brands need to pursue equipment that is high-speed, low-energy, and adaptable to various bottle shapes. In its early stages, the technology employed air spraying or electrostatic spraying combined with high-temperature curing to form a paint film. However, coatings have limited hardness, are easily scratched, and solvent evaporation leads to environmental problems. Dip coating and spray coating are suitable for simple shapes, but the film thickness uniformity is poor, the edges are prone to dripping, and the scratch resistance is insufficient. Advanced coating technology uses ultraviolet light to instantly cure acrylic resins, improving production efficiency and hardness, but the flexibility is poor and it is limited by the shape of the bottle. PVD (physical vapor deposition) deposits metal or ceramic materials onto the bottle surface after ionization in a vacuum environment to form a micron-scale film. It has high hardness, wear resistance, and is environmentally friendly, but the equipment investment is large and the requirements for surface uniformity are high. Silicon-based or carbon-based films are generated by gas phase chemical reaction, which have strong adhesion, but the process temperature is high, which limits the application of plastic bottles. Nano-coating technology uses the sol-gel method or nanoparticle dispersion to form a hydrophobic, fingerprint-resistant, and scratch-resistant transparent film, which is suitable for glass and plastic substrates, but has strict requirements for process stability.

[0003] According to patent number CN117026168A, a cosmetic bottle external coating device is proposed. In this device, the coating material is heated and diffused into the interior of a uniform mechanism by a heating device. A plastic cosmetic bottle is supported on the surface of a carrier component. Warm liquid cosmetic bottles are introduced into the connecting pipe, preheating the bottle. The engagement position of the driving component is located outside the uniform mechanism, meaning the rotation position is separated from the deposition position of the coating material. This solves the problem that coating material easily deposits on the surface of the rotating device, causing large variations in the size of the engagement position and preventing engagement and rotation. However, this device lacks corresponding drying and fixing measures. During coating, uneven coating can easily occur due to workpiece movement, and traditional fixing methods are cumbersome during workpiece loading and unloading. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a cosmetic bottle surface anti-scratch coating device, including a device base, a collection pool fixedly connected to the top of the device base, an external toothed ring fixedly connected to the top of the collection pool, a coating device fixedly connected to the bottom of the collection pool, a fixing device engaged with the inner wall of the external toothed ring, and the side of the fixing device away from the external toothed ring engaging with the side of the coating device. The fixing device includes a fixed slide tube, a limiting slide column fixedly connected to the top of the fixed slide tube, a sliding column slidably connected to the inner wall of the limiting slide column, a support plate fixedly connected to the side of the fixed slide tube, and a connecting base fixedly connected to the bottom of the fixed slide tube. The side of the connecting base meshes with the inner wall of the outer toothed ring. The workpiece is fitted with the top of the sliding column with its opening facing downwards and pressed down. The downward pressure of the sliding column drives the connecting base to rotate. The rotation of the connecting base drives the support plate to rotate along the side of the fixed slide tube, thereby facilitating the movement of the support plate into the interior of the workpiece. The support plate supports the inner wall side of the workpiece, thereby providing stable support for the workpiece. The rotation of the connecting base drives the fixed slide tube to rotate, thereby driving the workpiece to rotate. The rotation of the workpiece facilitates uniform spraying on the surface of the workpiece and removes excess paint, thus facilitating uniform spraying on the workpiece surface. The rotation of the sliding column facilitates the release of the workpiece after rotation, thus facilitating workpiece unloading.

[0005] Preferably, the sliding column includes a sliding shaft, a vertical sliding groove is provided on the side of the sliding shaft, a limiting sliding groove is provided on the inner wall side of the vertical sliding groove, a positioning groove is provided on the top of the sliding shaft, and a guide sliding hole is provided on the bottom of the sliding shaft. The sliding shaft is disposed inside the fixed sliding tube and is slidably connected to the inner wall of the fixed sliding tube through the limiting sliding column. The limiting sliding column extends into the interior of the vertical sliding groove and is slidably connected to the vertical sliding groove.

[0006] Preferably, the support plate includes a support base plate, a rotating frame fixedly connected to the side of the support base plate, a guide screw shaft rotatably connected to the center of the side of the support base plate, a spring plate fixedly connected to the side of the support base plate located on the rotating frame, a guide plate fixedly connected to the top of the support base plate, and a drive plate fixedly connected to the bottom of the support base plate. The support base plate is rotatably connected to the side of the fixed slide tube via the rotating frame. The side of the spring plate away from the support base plate is fixedly connected to the side of the fixed slide tube. The workpiece drives the sliding shaft to descend, and the descent of the sliding shaft causes the vertical slide groove to slide along the side of the limiting slide post. The limiting slide post slides along the inner wall of the vertical slide groove and enters the interior of the limiting slide groove, thereby limiting the limiting slide groove. This allows the limiting slide pin to be locked inside the limiting slide groove, keeping the sliding shaft in a descending posture. The positioning groove facilitates the adsorption and fixation of the top of the inner wall of the workpiece, thereby further increasing the stability of the workpiece. The inner wall of the workpiece slides along the side of the supporting base plate under the guidance of the guide plate, and through the contact of the guide screw shaft, the workpiece can rotate and descend along the side of the supporting base plate. During the process of the workpiece descending to the appropriate position, the side of the workpiece squeezes the side of the guide screw shaft, thereby driving the supporting base plate to rotate along the side of the rotating frame, and returning to its original position under the elastic force of the spring plate, thus supporting the inner side of the workpiece, and increasing the support area of ​​the inner wall of the workpiece through the guide screw shaft, thereby facilitating the fixation and stability of the workpiece.

[0007] Preferably, the connecting base includes a lower base plate, the top of which has an arc-shaped sliding hole, a guide post fixedly connected to the center of the top of the lower base plate, an upper top plate rotatably connected to the top of the lower base plate, a straight sliding hole on the top of the upper top plate, a rotating hole at the center of the top of the upper top plate, a limiting post slidably connected to the inner wall of the straight sliding hole, a toothed ring assembly sleeved and rotatably connected to the side of the lower base plate, the top of the upper top plate being fixedly connected to the bottom of the fixed sliding tube, the limiting post being located on one side of the drive plate, and the bottom of the limiting post extending into the interior of the arc-shaped sliding hole and slidably connected to the arc-shaped sliding hole.

[0008] Preferably, the gear ring assembly includes a rotating gear ring, a return spring fixedly connected to the inner wall side of the rotating gear ring, a connecting post fixedly connected to the end of the return spring away from the rotating gear ring, a rotating ring fixedly connected to the bottom of the rotating gear ring, the inner wall of the rotating gear ring fixedly connected to the side of the upper top plate, the top of the connecting post fixedly connected to the bottom of the lower bottom plate, the side of the rotating gear ring meshing with the inner wall of the outer gear ring, and the rotating ring rotatably connected to the bottom of the coating device via a bracket. The sliding shaft descends, driving the guide slide... The hole moves along the top of the guide post. The guide hole guides the guide post, causing it to rotate. The rotation of the guide post causes the lower base plate to rotate, which in turn causes the connecting post to rotate. The rotation of the connecting post causes the return spring to deform, generating elastic force. The rotation of the lower base plate causes the arc-shaped sliding hole to move, which in turn causes the limiting post to slide along the inner wall of the straight sliding hole. The upper top plate is fixedly connected to the inner wall of the self-rotating gear ring, causing the lower base plate and the upper top plate to rotate relative to each other. The straight sliding hole in the upper top plate, along with the arc-shaped sliding hole, causes the limiting post to slide. While moving, it slides along the inner wall of the arc-shaped sliding hole, thereby driving the limiting post to slide along the top of the straight sliding hole, which in turn drives the drive plate to move. The movement of the drive plate drives the support base plate to rotate along the side of the rotating frame, thus making it easier to keep the support base plate vertical along the inner wall of the workpiece, thereby increasing the clamping firmness of the workpiece. When the workpiece is coated and removed, the workpiece is pressed down and rotated, driving the sliding shaft. The rotation of the sliding shaft causes the limiting sliding post to disengage from the inside of the limiting sliding groove, thus facilitating the rotation of the connecting post under the accumulated elastic force of the return spring. The rotation of the connecting post drives the lower base plate to rotate, and the rotation of the lower base plate drives the guide post to rotate. The rotation of the guide post drives the sliding shaft to slide along the inner wall of the fixed sliding tube through the guide sliding hole, thereby driving the sliding shaft to rise through the cooperation of the guide sliding hole and the guide post, thus moving the workpiece and facilitating unloading. During the unloading process, the limiting post releases its restriction on the drive plate, thereby driving the support base plate to adjust to an inclined state under the elastic force of the spring plate, thus facilitating the unloading of the workpiece.

[0009] Preferably, the coating device includes a drive gear, a main motor is fixedly connected to the bottom of the drive gear, a storage tank is fixedly connected to the top of the drive gear, an atomizing nozzle is connected to the side of the storage tank, a scraping assembly is rotatably connected to the inner wall of the storage tank, the bottom of the main motor is fixedly connected to the bottom of the inner wall of the collection tank, and the side of the drive gear meshes with the side of the rotating gear ring.

[0010] Preferably, the scraping assembly (including a scraping tube with scraping holes on its side, a limiting frame fixedly connected to the top of the scraping tube, a heating rod fixedly connected to the bottom of the limiting frame, a reflector fixedly connected to the bottom of the limiting frame on one side of the heating rod, and the bottom of the reflector fixedly connected to the top of the external toothed ring) is arranged inside the storage tank and rotatably connected to the storage tank. The raw material is guided through the inside of the storage tank and sprayed laterally along the atomizing nozzle. The coating liquid is sprayed along the atomizing nozzle and coats the surface of the workpiece. The workpiece rotates under the action of the rotating toothed ring, thus achieving no dead angle spraying on the workpiece. The main motor is started, and the main motor rotates... The drive gear rotates, which in turn drives the storage tank to rotate. This rotation, in turn, causes the self-rotating gear ring to rotate and move along the inner wall of the outer gear ring, thus achieving thorough coating of the workpiece without any blind spots. While the storage tank rotates, the scraping tube inside the tank remains relatively stationary. The scraping holes are used to release the coating solution and continuously scrape the inlet of the atomizing nozzle, preventing blockages that could lead to uneven coating. The coating agent on the workpiece surface is dried by a heating rod, and the reflector ensures that the heat radiation from the heating rod is concentrated on the workpiece surface, facilitating drying after coating and ensuring coating quality.

[0011] This invention provides a device for applying an anti-scratch coating to the surface of cosmetic bottles. It offers the following advantages: 1. This cosmetic bottle surface anti-scratch coating equipment is equipped with a connecting base. During operation, the workpiece is fitted onto the top of the sliding column with its opening facing downwards and is pressed down. The downward movement of the sliding column further drives the connecting base to rotate, and the rotation of the connecting base causes the support plate to rotate along the side of the fixed slide tube, thereby allowing the support plate to smoothly move into the workpiece. After entering the workpiece, the support plate provides effective support to its inner wall side, ensuring the stability of the workpiece during processing. At the same time, the rotation of the connecting base also drives the fixed slide tube to rotate, thus causing the entire workpiece to rotate. The rotation of the workpiece helps to achieve uniform spray coating coverage on its surface, and the rotation causes excess coating to be removed under centrifugal force, thereby improving the uniformity of the surface coating. Finally, through the linkage control of the sliding column, the workpiece can be smoothly released after rotation, achieving convenient unloading.

[0012] 2. This cosmetic bottle surface anti-scratch coating equipment is equipped with a vertical slide groove. As the workpiece moves downwards, it drives the sliding shaft to descend. The downward movement of the sliding shaft forces the vertical slide groove to slide along the side of a limiting slide post. During this process, the limiting slide post slides into the inner wall of the vertical slide groove and enters the groove, creating a limiting effect and locking the sliding shaft in the descending state. A positioning groove on the equipment can adsorb and fix the top of the workpiece's inner wall, further enhancing the workpiece's clamping stability. Guided by the guide plate, the workpiece's inner wall slides along the side of the support base plate and rotates downwards along the side of the support base plate through contact with the guide spiral shaft. When the workpiece reaches the appropriate position, its side continuously presses against the guide spiral shaft, causing the support base plate to rotate along the rotating frame and return to its original position with the help of the elasticity of the spring sheet, thus supporting the inner side of the workpiece. The design of the guide spiral shaft increases the contact area with the inner wall of the workpiece, thereby improving the overall stability of the workpiece fixation.

[0013] 3. This cosmetic bottle surface anti-scratch coating equipment is equipped with a connecting column. When the sliding shaft descends, it drives the guide slide hole to move along the top of the guide column. The guide slide hole, through its guiding action, causes the guide column to rotate. The rotation of the guide column is transmitted to the lower base plate, causing it to rotate, which in turn causes the connecting column to rotate as well. The rotation of the connecting column causes the return spring to deform and accumulate elastic potential energy. When the lower base plate rotates, the arc-shaped slide hole on it is displaced accordingly, pushing the limiting column to slide along the inner wall of the straight slide hole. Since the upper top plate is fixedly connected to the inner wall of the self-rotating gear ring, the lower base plate and the upper top plate rotate relative to each other. The straight slide hole opened in the upper top plate moves along the inner wall of the arc-shaped slide hole while the limiting column is sliding, thereby driving the limiting column to slide along the top of the straight slide hole and causing the drive plate to move. The movement of the drive plate further pushes the support base plate to rotate along the rotating frame, keeping it perpendicular to the inner wall of the workpiece, thereby enhancing the clamping firmness of the workpiece. When the workpiece is finished painting and needs to be removed, the workpiece is pressed down and rotated, causing the sliding shaft to move and disengage the limiting slide post from the limiting slide groove. At this time, the accumulated elastic force of the return spring is released, causing the connecting column to rotate. The rotation of the connecting column drives the lower base plate and guide column to rotate accordingly. The guide column drives the sliding shaft to move upward along the inner wall of the fixed slide tube through the guide slide hole, thereby raising the position of the workpiece for easy unloading. During this process, the limiting column releases its restriction on the drive plate, and the supporting base plate returns to its tilted state under the elastic force of the spring plate, facilitating the smooth removal of the workpiece.

[0014] 4. This cosmetic bottle surface anti-scratch coating equipment is equipped with an atomizing nozzle. The coating material is guided from the storage tank and then sprayed laterally onto the workpiece surface through the atomizing nozzle. The coating liquid is atomized into a uniform mist by the atomizing nozzle, enveloping the outer wall of the workpiece. Simultaneously, the workpiece continuously rotates under the drive of a rotating gear ring, achieving coating without dead angles. After the main motor is started, the drive gear rotates, driving the entire storage tank to rotate. The drive gear simultaneously drives the rotating gear ring, causing it to move along the inner wall of the outer gear ring while rotating, thus ensuring all-round coverage of the workpiece. While the storage tank rotates, its internal scraping tube remains stationary, and the scraping holes continuously release coating liquid and scrape and clean the inlet of the atomizing nozzle, preventing blockages that could affect the uniformity of the coating. The equipment also includes a heating rod for drying the coating agent on the workpiece surface. Combined with a reflector, heat is concentrated and radiated onto the workpiece surface, achieving rapid drying after coating and ensuring the quality and adhesion of the coating layer.

[0017] The technical solutions of the embodiments 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] For the first embodiment, please refer to... Figures 1-2 The present invention provides a technical solution: a cosmetic bottle surface anti-scratch coating device, including a device base 1, a collection pool 2 fixedly connected to the top of the device base 1, an external toothed ring 4 fixedly connected to the top of the collection pool 2, a coating device 3 fixedly connected to the bottom of the collection pool 2, a fixing device 5 engaged with the inner wall of the external toothed ring 4, and the side of the fixing device 5 away from the external toothed ring 4 engaging with the side of the coating device 3. The fixing device 5 includes a fixing slide tube 501, a limiting slide post 502 fixedly connected to the top of the fixing slide tube 501, a sliding post 503 slidably connected to the inner wall of the limiting slide post 502, a support plate 504 fixedly connected to the side of the fixing slide tube 501, and a connecting base 505 fixedly connected to the bottom of the fixing slide tube 501. The side of the connecting base 505 meshes with the inner wall of the outer toothed ring 4.

[0019] The workpiece, with its opening facing downwards, is fitted onto the top of the sliding column 503 and pressed down. The downward pressure of the sliding column 503 causes the connecting base 505 to rotate. The rotation of the connecting base 505 causes the support plate 504 to rotate along the side of the fixed slide tube 501, thus facilitating the movement of the support plate 504 into the interior of the workpiece. The support plate 504 supports the inner wall side of the workpiece, thus providing stable support for the workpiece. The rotation of the connecting base 505 causes the fixed slide tube 501 to rotate, thereby causing the workpiece to rotate. The rotation of the workpiece facilitates uniform spraying on its surface and removes excess paint, ensuring even spraying on the workpiece surface. The sliding column 503 facilitates the release of the workpiece after rotation, thus enabling the workpiece to be unloaded.

[0020] Second embodiment, please refer to Figures 1-4 Based on the first embodiment, the present invention provides a technical solution: the sliding column 503 includes a sliding shaft 5031, a vertical sliding groove 5032 is provided on the side of the sliding shaft 5031, a limiting sliding groove 5033 is provided on the inner wall side of the vertical sliding groove 5032, a positioning groove 5034 is provided on the top of the sliding shaft 5031, a guide sliding hole 5035 is provided on the bottom of the sliding shaft 5031, the sliding shaft 5031 is disposed inside the fixed sliding tube 501 and is slidably connected to the inner wall of the fixed sliding tube 501 through the limiting sliding column 502, the limiting sliding column 502 extends into the interior of the vertical sliding groove 5032 and is slidably connected to the vertical sliding groove 5032.

[0021] The support plate 504 includes a support base plate 5041, a rotating frame 5042 fixedly connected to the side of the support base plate 5041, a guide screw shaft 5043 rotatably connected to the center of the side of the support base plate 5041, a spring plate 5044 fixedly connected to one side of the support base plate 5041 located on the rotating frame 5042, a guide plate 5045 fixedly connected to the top of the support base plate 5041, a drive plate 5046 fixedly connected to the bottom of the support base plate 5041, the support base plate 5041 rotatably connected to the side of the fixed slide tube 501 through the rotating frame 5042, and the side of the spring plate 5044 away from the support base plate 5041 fixedly connected to the side of the fixed slide tube 501.

[0022] The workpiece drives the sliding shaft 5031 to descend. The descent of the sliding shaft 5031 causes the vertical slide groove 5032 to slide along the side of the limiting slide post 502. The limiting slide post 502 slides along the inner wall of the vertical slide groove 5032 and enters the interior of the limiting slide groove 5033, thus limiting the limiting slide groove 5033. This keeps the limiting slide post 502 locked inside the limiting slide groove 5033, maintaining the descending posture of the sliding shaft 5031. The positioning groove 5034 facilitates the adsorption and fixation of the top of the inner wall of the workpiece, further increasing the stability of the workpiece. The inner wall of the workpiece is guided by the guide plate 504. The guide 5 slides along the side of the support base plate 5041 and contacts the guide screw shaft 5043, which facilitates the workpiece to rotate and descend along the side of the support base plate 5041. During the process of the workpiece descending to the appropriate position, the side of the workpiece squeezes the side of the guide screw shaft 5043, thereby driving the support base plate 5041 to rotate along the side of the rotating frame 5042, and returning to its original position under the elastic force of the spring plate 5044, thereby supporting the inner side of the workpiece, and increasing the support area of ​​the inner wall of the workpiece through the guide screw shaft 5043, thus facilitating the fixation and stability of the workpiece.

[0023] Third embodiment, please refer to Figures 1-6 Based on the second embodiment, the present invention provides a technical solution: the connecting base 505 includes a lower base plate 5051, an arc-shaped sliding hole 5052 is provided on the top of the lower base plate 5051, a guide post 5053 is fixedly connected to the center of the top of the lower base plate 5051, an upper top plate 5054 is rotatably connected to the top of the lower base plate 5051, a straight sliding hole 5055 is provided on the top of the upper top plate 5054, a rotating hole 5056 is provided at the center of the top of the upper top plate 5054, a limiting post 5057 is slidably connected to the inner wall side of the straight sliding hole 5055, a toothed ring assembly 5058 is sleeved and rotatably connected to the side of the lower base plate 5051, the top of the upper top plate 5054 is fixedly connected to the bottom of the fixed sliding tube 501, the limiting post 5057 is located on one side of the drive plate 5046, and the bottom of the limiting post 5057 extends into the interior of the arc-shaped sliding hole 5052 and is slidably connected to the arc-shaped sliding hole 5052.

[0024] The gear ring assembly 5058 includes a rotating gear ring 50581. A return spring 50582 is fixedly connected to the inner side of the rotating gear ring 50581. A connecting post 50583 is fixedly connected to the end of the return spring 50582 away from the rotating gear ring 50581. A rotating ring 50584 is fixedly connected to the bottom of the rotating gear ring 50581. The inner wall of the rotating gear ring 50581 is fixedly connected to the side of the upper top plate 5054. The top of the connecting post 50583 is fixedly connected to the bottom of the lower bottom plate 5051. The side of the rotating gear ring 50581 meshes with the inner wall of the outer gear ring 4. The rotating ring 50584 is rotatably connected to the bottom of the coating device 3 through a bracket.

[0025] The sliding shaft 5031 descends, causing the guide sliding hole 5035 to move along the top of the guide post 5053. The guide sliding hole 5035 guides the guide post 5053, causing the guide post 5053 to rotate. The rotation of the guide post 5053 causes the lower base plate 5051 to rotate. The rotation of the lower base plate 5051 causes the connecting post 50583 to rotate. The rotation of the connecting post 50583 causes the return spring 50582 to deform, thereby generating elastic force. The rotation of the lower base plate 5051 causes the arc-shaped sliding hole 5052 to move. The movement of the arc-shaped sliding hole 5052 causes the limiting post 5057 to move. The upper top plate 5054 slides along the inner wall of the straight sliding hole 5055. The upper top plate 5054 is fixedly connected to the inner wall of the rotating gear ring 50581, causing the lower bottom plate 5051 and the upper top plate 5054 to rotate relative to each other. The straight sliding hole 5055 in the upper top plate 5054 slides along the inner wall of the arc-shaped sliding hole 5052 while the limiting post 5057 slides. This drives the limiting post 5057 to slide along the top of the straight sliding hole 5055, thereby moving the drive plate 5046. The movement of the drive plate 5046 causes the supporting bottom plate 5041 to move along the rotating frame. The side of 5042 rotates, facilitating the drive support base plate 5041 to remain perpendicular to the inner wall of the workpiece, thereby increasing the clamping firmness of the workpiece. When the workpiece is finished with coating and removed, the workpiece is pressed down and rotated, driving the sliding shaft 5031. The rotation of the sliding shaft 5031 causes the limiting sliding column 502 to disengage from the limiting sliding groove 5033, thus facilitating the rotation of the connecting column 50583 under the accumulated elastic force of the return spring 50582. The rotation of the connecting column 50583 drives the lower base plate 5051 to rotate, and the rotation of the lower base plate 5051 drives... The guide post 5053 rotates, and the rotation of the guide post 5053 drives the sliding shaft 5031 to slide along the inner wall of the fixed slide tube 501 through the guide sliding hole 5035. Thus, through the cooperation of the guide sliding hole 5035 and the guide post 5053, the sliding shaft 5031 is driven to rise, thereby driving the workpiece to move, which facilitates unloading. During the unloading process, the limiting post 5057 releases the restriction on the drive plate 5046, and under the elastic force of the spring plate 5044, the support base plate 5041 is adjusted to an inclined state, which facilitates the unloading of the workpiece.

The bottom of the reflector plate 3055 is fixedly connected to the top of the outer toothed ring 4. The scraping tube 3051 is disposed inside the storage tank 303 and is rotatably connected to the storage tank 303.

[0028] The raw material is guided through the interior of the storage tank 303 and sprayed laterally along the atomizing nozzle 304. The coating liquid is sprayed along the atomizing nozzle 304 and coats the surface of the workpiece. Driven by the rotating gear ring 50581, the workpiece is rotated, thus achieving coating without dead angles. The main motor 302 is started, and its rotation drives the drive gear 301 to rotate. The drive gear 301 rotates, which in turn rotates the storage tank 303, which in turn rotates the rotating gear ring 50581. This rotation of the gear ring 50581, along with the external gear ring, causes the coating liquid to rotate. The inner wall of the 4 moves to spray the workpiece without dead angles. While the storage tank 303 rotates, the scraping tube 3051 inside the storage tank 303 remains relatively stationary. The scraping hole 3052 is used to release the coating liquid and continuously scrape the water inlet of the atomizing nozzle 304, thereby avoiding the uniform reduction of coating caused by clogging. The coating agent on the surface of the workpiece is dried by the heating rod 3054. At the same time, the setting of the reflector plate 3055 makes it easy for the heat radiation of the heating rod 3054 to be concentrated on the surface of the workpiece, thereby facilitating drying after coating and ensuring coating quality.
