Description

Technical Field

[0001] The invention belongs to the technical field of glass panels for household appliances, and in particular relates to a coating device for depositing a colored nano-coating on the surface of glass for household appliances. Background Art

[0002] Currently, home appliances such as refrigerators, freezers, and air conditioners often use glass panels with various patterns for surface decoration. Refrigerators, in particular, feature a stylish and elegant appearance. However, creating these patterns requires depositing a colored nano-coating on the glass panels. Applying a colored coating to existing glass surfaces requires a complex process, resulting in relatively large color variations.

[0003] When spraying nano-coating materials on the surface of home appliance glass, the existing spraying method is to use a handheld sprayer to spray the surface of home appliance glass. The spraying is very uneven, the movement speed of the handheld spray head is unstable, and the pressure of each nozzle is difficult to be the same, so the sprayed nano-coating material is unevenly distributed. Then, it cannot be dried after coating, resulting in partial rubbing off during manual transportation, which greatly affects product quality. Summary of the Invention

A threaded sleeve 29 is threadedly connected to the surface of the threaded rod 1 28. The threaded sleeve 29 is slidably connected to the vertical plate 21 on the side closest to the vertical plate 21.

A connected discharge pipe 24 is installed on the outside of the suction pump 23, and the end of the discharge pipe 24 away from the suction pump 23 passes through the "┎"-shaped vertical plate 21 and extends to the outside thereof. A telescopic tube 25 is installed on the end of the discharge pipe 24 away from the suction pump 23, and the other end of the telescopic tube 25 is installed with a spraying mechanism 26 through a connecting pipe; the top of the connecting pipe is fixed on the threaded sleeve 29, and a fixed block 210 is installed at the bottom of the outside of the connecting pipe, a fixed frame 211 is installed on the outside of the fixed block 210, and fans 212 are installed on the top of both sides of the inner wall of the fixed frame 211.

[0026] A stabilizing plate 5 is installed on the outer side of the “┎”-shaped vertical plate 21 , and a positioning rod 6 is installed on the outer side of the fixing frame 211 . One end of the positioning rod 6 passes through the stabilizing plate 5 and extends to the outside thereof.

[0027] See you next time Figure 3 The support mechanism 4 includes a symmetrically arranged support part, which includes a horizontal plate 40, a transmission plate 45, a mounting frame 46, and a limiting roller 47; one horizontal plate 40 is fixed on the "┎"-shaped vertical plate 21, and the other is fixed on the vertical end of the base plate 1; the top of each horizontal plate 40 is slidably connected to a transmission plate 45, and the tops of the two transmission plates 45 are fixedly connected to the mounting frame 46 on the side close to each other, and the two mounting frames 46 are provided with a limiting roller 47 on the side close to each other, and the home appliance glass to be sprayed is supported on the limiting roller 47.

[0030] Once the glass is placed, the suction pump 23 is activated to draw the nano-coating from the storage box 22 into the discharge pipe 24. The discharge pipe 24 then transports the nano-coating to the telescopic tube 25, ultimately entering the transition box 261 of the spraying mechanism 26. The end of the transition box 261 is then transported to the vertical pipe 263 via the connecting hose 262. The nano-coating is then transported through the vertical pipe 263 to the spray head 264 for spraying onto the glass below. After spraying is complete, the fan 212 is activated for drying.

[0033] The remaining material dripping after coating is collected and reused by the collection box 3, which can effectively concentrate and recycle the coating dripping during the equipment processing.

[0034] Example 2 This embodiment provides a device for depositing colored nano-coating on the glass surface of household appliances, and its structure is basically the same as that of embodiment 1, except that this embodiment further discloses the structure of a nozzle machine 264 based on embodiment 1. Specifically, the nozzle machine 264 includes a horizontal tube 2641, and the horizontal tube 2641 is fixedly connected to the vertical tube 263, and the vertical tube 263 is fixedly connected to the center of the horizontal tube 2641; the internal ends of the horizontal tube 2641 are provided with inner grooves 2642, and the cross sections of the inner grooves 2642 are both circular, and the interiors of the two inner grooves 2642 are slidably connected with a slide cylinder 2643, and the slide cylinder 2643 is provided with an inner groove 2644, and the upper and lower ends of the horizontal tube 2641 are provided with inner grooves 2642.

The thin rods 2647 are slidably connected to the corresponding sliding holes 2646. A plurality of nozzle slots 2649 are respectively provided corresponding to their corresponding nozzles 2640.

[0036] A plurality of spray grooves 2649 are provided on one side surface of the two slides 2643. The pressure pushes the two slides 2643 to slide toward both ends, pushing the corresponding springs 2648 to slide. When the thick rod 2645 contacts the end wall of the inner slide groove 2642, the spray groove 2649 is just aligned with the nozzle 2640. At this time, the pressure in the inner groove 2644 is equal, so that the spraying pressure of each spray groove 2649 is the same, and the sprayed nano-coating paint is more uniform.

[0037] Example 3 This embodiment provides a device for depositing a colored nano-coating on the surface of household appliance glass. Its structure is basically the same as that of Example 1, except that, based on Example 1, this embodiment further discloses that the inner wall of the horizontal plate 40 is fixedly connected to a motor II 41 on the side away from each other, and the output end of the motor II 41 is fixedly connected to a threaded rod II 42.
