Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to a tank recoating dryer. Background Technology

[0002] During production, transportation, or use, the surface coating of the tank may suffer damage such as scratches, rust, and peeling. To restore its protective performance (such as corrosion resistance and oxidation resistance) and appearance quality, the damaged areas need to be recoated. The recoated coating needs to be cured by drying to ensure a firm bond with the tank surface and prevent it from falling off. Commonly used equipment for tank recoating and drying includes hot air circulating ovens, infrared drying equipment, ultraviolet curing equipment, tunnel drying lines, and gas-fired hot air furnaces with drying rooms suitable for large tanks.

[0003] In existing technologies for drying cans in hot air circulating ovens, trays or grid frames are typically used as support structures. However, during the recoating process on the cans, paint dripping is an unavoidable problem. With ordinary tray structures, dripping paint easily accumulates and forms residue, which is not only difficult to clean but may also affect the normal operation of the oven and the drying quality of the cans. While grid structures allow paint to leak out, they cannot prevent paint from dripping onto the cans on the lower grid trays, which also has an adverse effect on the appearance and quality of the cans.

[0004] Therefore, we propose a tank coating dryer. Utility Model Content

[0005] This utility model provides a can-type recoating and drying machine. It features a structure with a mesh plate and tray assembly inside the drying oven. The tray assembly utilizes a non-woven fabric located below the mesh plate to absorb paint seeping through the mesh, and a PE coating on the surface of the non-woven fabric further prevents paint penetration. Simultaneously, a sliding block on the outer wall of the frame engages with a support groove and is magnetically secured to ensure the stability of the tray assembly. Furthermore, nested outer, middle, and inner rails ensure smooth drawer operation. This design effectively collects and treats paint drips, ensures a stable tray assembly, smooth drawer operation, and facilitates the replacement of the non-woven fabric, thereby solving the problems mentioned in the background art. When existing tanks are used for touch-up coating and drying, trays tend to accumulate paint residue that is difficult to clean, while grid frames can cause paint to drip onto the lower tanks, affecting the appearance and quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A tank coating dryer includes an oven, inside which are provided two supports, and between the two supports are provided multiple tray assemblies. A wire mesh is fixedly connected to the top of each tray assembly, and the wire mesh has multiple grids inside. The tray assembly includes a nonwoven fabric located directly below the mesh panel. The tray assembly is used to collect the paint seeping out from the mesh panel, and the nonwoven fabric is used to absorb dripping material.

[0007] Preferably, the tray assembly further includes an outer frame, which is fixedly connected to the bottom of the mesh panel. The outer frame has a U-shaped structure, and a drawer is provided on the inner wall of the outer frame. A slide rail is provided between the drawer and the outer frame.

[0008] Preferably, the drawer is provided with non-woven fabric inside, which is used to absorb dripping paint. The surface of the non-woven fabric is coated with a PE film, which forms a barrier structure to prevent low-viscosity paint from penetrating.

[0009] Preferably, the outer wall of the outer frame is provided with a slider, and the inside of the bracket is provided with multiple sliding grooves, and the slider is slidably connected inside the sliding grooves of the bracket.

[0010] Preferably, both the slider end and the bracket groove end are provided with magnets, and the two magnets attract each other to adsorb and fix the slider inside the bracket groove.

[0011] Preferably, the slide rail includes an outer rail, which is fixedly connected to the inner wall of the drawer. An inner rail is fixedly connected to the outer wall of the drawer. A middle rail is nested between the inner rail and the outer rail. The outer rail provides external accommodation and guiding space for the middle rail. The middle rail can slide relative to the inner rail along the internal track structure of the outer rail. The middle rail provides internal support and guidance for the inner rail, which slides on the internal track of the middle rail.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In a tank recoating and drying machine, a tray assembly is set up in conjunction with a mesh plate, allowing paint dripping during recoating to seep through the mesh plate and be absorbed and collected by the non-woven fabric below the mesh plate. Compared with the existing trays that easily accumulate residue and the mesh frame that causes paint to drip into the lower tank, the non-woven fabric can directly absorb the material. Even if the material solidifies after drying, it can be replaced and discarded along with the non-woven fabric as a whole, eliminating the need for cumbersome tray cleaning or handling of dripping paint from the lower layer, greatly simplifying the cleaning process. In addition, the non-woven fabric surface is coated with a PE film to form a barrier structure, which can prevent low-viscosity paint from penetrating and avoid contaminating equipment parts, solving the problem of insufficient protection of traditional support structures.

[0013] 2. In a can-type coating dryer, a multi-layered nested sliding rail system consisting of outer, middle, and inner rails is used to achieve the pull-out action between the drawer and the outer frame. Compared with existing single-rail and simple double-rail pull-out technologies, the multi-layered nested rails result in more even force distribution, smoother pull-out without jamming or shaking, and are less prone to rail deformation and wear due to uneven force distribution over long-term use, thus improving the user experience and component lifespan. At the same time, the multi-layered rails increase the contact area and force points, resulting in stronger load-bearing capacity and adaptability to heavier load-bearing requirements. Furthermore, the multi-stage guide ensures precise drawer pull-out trajectory, preventing deviation and skewing, ensuring the precision of component matching, and reducing abnormal wear.

[0014] 3. In a tank coating dryer, the outer frame outer wall slider cooperates with the bracket slide groove, and is fixed by end magnet adsorption, making the installation and removal of the tray assembly on the bracket more convenient. It is easy to adjust the spacing height between multiple tray assemblies and the mesh plate according to the height of the tank. Moreover, the magnetic fixation enhances the stability of the tray assembly after installation, reducing abnormal noises caused by loose connections during use, and component displacement.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example Please see Figure 1 - Figure 7 The can body recoating dryer shown includes an oven 1, with two supports 11 inside the oven 1, and multiple tray assemblies 13 between the two supports 11. A mesh plate 12 is fixedly connected to the top of the tray assembly 13, and multiple meshes are provided inside the mesh plate 12. The tray assembly 13 includes a nonwoven fabric 131 located directly below the mesh plate 12. The tray assembly 13 is used to collect the paint seeping out of the mesh plate 12, and the nonwoven fabric 131 is used to absorb the dripping material.

[0019] For details, please refer to Figure 4 and Figure 6 As shown, the tray assembly 13 also includes an outer frame 132, which is fixedly connected to the bottom of the mesh plate 12. The outer frame 132 has a U-shaped structure, and a drawer 130 is provided on the inner wall of the outer frame 132. A slide rail 134 is provided between the drawer 130 and the outer frame 132. The inside of the drawer 130 is provided with non-woven fabric 131, which is used to absorb dripping paint. A PE film is laminated on the surface of the non-woven fabric 131, and the PE film of the non-woven fabric 131 forms a barrier structure to prevent low-viscosity paint from penetrating.

[0020] In existing technologies, ordinary trays are difficult to clean the residue formed by dripping paint, and grid frames cannot prevent paint drips from contaminating the lower tank. However, in this design, when paint drips during recoating, it seeps through the mesh of the grid plate 12 and is absorbed and collected by the non-woven fabric 131 below the grid plate 12. Since the non-woven fabric 131 is a fibrous structure, it has its own adsorption properties and can directly adsorb the dripping material. Even if the material solidifies after drying, it can be replaced and discarded as a whole with the non-woven fabric 131. Unlike cleaning traditional trays, there is no need to painstakingly remove residue, and there is no need to worry about the lower tank being contaminated by dripping paint, which greatly simplifies the cleaning process. Moreover, the composite PE film on the surface of the non-woven fabric 131 forms a barrier structure. Low-viscosity paint is blocked from penetrating when it comes into contact with this film and will not contaminate the equipment parts, thus solving the drawbacks of existing technologies from the source.

[0021] The outer frame 132 of the tray assembly 13 is fixedly connected to the bottom of the wire mesh 12, providing stable support for the wire mesh 12 above; and a drawer 130 is provided on the inner wall of the outer frame 132. The drawer 130 is connected to the outer frame 132 by a slide rail 134. The slide rail 134 ensures that the drawer 130 can slide smoothly relative to the outer frame 132, making it easy to pull out the drawer 130 when needed.

[0022] By placing nonwoven fabric 131 inside the drawer 130 of the tray assembly 13, the nonwoven fabric 131 can absorb paint dripping from the mesh of the wire mesh 12 based on its own physical properties. Since the nonwoven fabric 131 is made of fibers through a specific process, it has many tiny pores. These pores can absorb paint liquid through capillary action. When paint drips and comes into contact with the nonwoven fabric 131, it will be absorbed and retained in the pores by capillary action. At the same time, a layer of PE film laminated on the surface of the nonwoven fabric 131 forms an effective barrier structure. With the low permeability of the PE film, even low viscosity paint can be prevented from penetrating further, avoiding paint from dripping through the nonwoven fabric 131 and dripping to the bottom of the drawer 130 and causing pollution. It also prevents paint from accumulating in the tray assembly 13 and forming residue.

[0023] It should be noted that the non-woven fabric 131 used here is designed for single use. After the tank is coated and dried, the non-woven fabric 131 can be replaced simultaneously when the tank is removed. This is because during the drying process, the paint dripping onto the non-woven fabric 131 will gradually clump together on the non-woven fabric 131 due to factors such as temperature rise and solvent evaporation. The paint clumps form a relatively stable adhesion state with the non-woven fabric 131, so that when the non-woven fabric 131 is replaced, these clumps can be easily cleaned out of the drawer 130 along with the non-woven fabric 131, without remaining inside the drawer 130. This maintains the cleanliness of the drawer 130 and ensures that the tray assembly 13 can still effectively prevent paint drips and contamination during the next use. This ensures that the tank is not affected by paint drips during the entire drying process, ensuring high-quality and stable drying work, and greatly improving the overall practicality and operability of the equipment.

[0024] Among them, see Figure 3 and Figure 4 As shown, the outer wall of the outer frame 132 is provided with a slider 133, and the bracket 11 is provided with multiple grooves. The slider 133 is slidably connected to the groove of the bracket 11. Both the end of the slider 133 and the end of the groove of the bracket 11 are provided with magnets 14. The two magnets 14 attract each other and are used to attract and fix the slider 133 to the groove of the bracket 11.

[0025] The slider 133 set on the outer wall of the outer frame 132 of the tray assembly 13 cooperates with the sliding groove inside the bracket 11 to form a sliding connection structure, which allows the tray assembly 13 to be flexibly adjusted along the sliding groove of the bracket 11. The installation position on the bracket 11 can be changed according to actual needs, which makes it convenient to reasonably arrange the distance and quantity of the tray assemblies 13 according to different tank sizes, drying process requirements and other factors.

[0026] Magnets 14 are provided at both ends of the slider 133 and the slide groove of the bracket 11. Utilizing the mutual attraction between the magnets 14, when the slider 133 slides to the appropriate position, the attraction generated between the magnets 14 at both ends can firmly attract and fix the slider 133 inside the slide groove of the bracket 11. This ensures that the tray assembly 13 is stably placed in the set position, avoiding displacement of the tray assembly 13 due to vibrations caused by equipment operation or external force interference when placing or removing the tank during the drying process. This ensures the stability of the entire tray assembly 13 within the oven 1 and lays the foundation for the orderly placement of the tank and the orderly conduct of the drying work.

[0027] Additionally, see Figure 7 As shown, the slide rail 134 includes an outer rail 1340, which is fixedly connected to the inner wall of the drawer 130. An inner rail 1342 is fixedly connected to the outer wall of the drawer 130. A middle rail 1341 is nested between the inner rail 1342 and the outer rail 1340. The outer rail 1340 provides external space for the middle rail 1341 to accommodate and guide it. The middle rail 1341 can slide relative to the inner rail 1340 along its internal track structure. The middle rail 1341 provides internal support and guidance for the inner rail 1342, which slides on the internal track of the middle rail 1341.

[0028] In practice, we often need to pull out drawer 130 to replace the non-woven fabric 131 that has absorbed paint. This places high demands on the smoothness and stability of the drawer 130's pull-out. In the existing technology, ordinary single-rail or simple double-rail pull-out structures are prone to jamming and shaking after long-term use, have poor load-bearing capacity, and are easy to wear. However, the slide rail 134 in this design adopts a nested structure of outer rail 1340, middle rail 1341, and inner rail 1342. When drawer 130 needs to be operated, such as pulling out or pushing in, the outer rail 1340 first provides external space for the middle rail 1341 to accommodate and guide. The middle rail 1341 can slide relative to the internal track structure of the outer rail 1340. This sliding is achieved based on the fit between the tracks and the reasonable structural design, ensuring the directionality and stability of the sliding. Meanwhile, the middle rail 1341 provides internal support and guidance for the inner rail 1342, allowing the inner rail 1342 to slide on the internal track of the middle rail 1341. In this way, the inner rail 1342, the middle rail 1341, and the outer rail 1340 work together to decompose and guide the sliding motion of the drawer 130 relative to the outer frame 132 through layers of relative sliding relationships. This allows the drawer 130 to slide smoothly and stably relative to the outer frame 132, facilitating operations such as replacing the non-woven fabric 131 placed inside the drawer 130 to absorb dripping paint during the drying process. This ensures that the entire tank recoating and drying work can be carried out in an orderly manner.
