Description

Technical Field

[0001] The utility model relates to the technical field of furniture plate painting, in particular to a dust-free electrostatic painting circulation device. Background Art

[0002] In a closed environment, the dust-free electrostatic paint circulation system uses the principle of electrostatic adsorption to evenly adhere paint particles to the surface of the wood panel, ensuring a uniform paint layer thickness and avoiding the uneven thickness that can occur with traditional spray painting methods. The paint layer adheres tightly to the wood panel surface, providing strong adhesion and resisting chipping or flaking, thereby increasing the durability and lifespan of the furniture.

[0003] Because panels often vary in shape and size, and the fixed position of the nozzle limits the spray range, it's difficult to fully cover the entire panel surface, potentially leading to uneven paint layer thickness. For example, spraying too close can result in an overly thick paint layer, causing sagging or an orange peel effect; while spraying too far can result in a thinner paint layer and poor adhesion. This unevenness not only affects aesthetics but also reduces the adhesion and durability of the paint layer. Utility Model Content

[0004] Based on this, the utility model provides a dust-free electrostatic paint spraying circulation device with a simple structure and easy use. The telescopic cylinder is connected to the movable plate, and the suction cup on the movable plate is used to adsorb the plate.

[0025] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0026] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figures 1 to 5 , which is a dust-free electrostatic paint circulation device in one embodiment of the present invention, includes a paint spraying room 10, a hanging assembly 20 slidably connected to the top of the paint spraying room 10, and a paint spraying assembly 30 installed on one side of the paint spraying room 10.

[0029] The spray booth 10 includes a frame 11, a circulating guide rail 12 mounted on the top of the frame 11, a slider 13 connected to the circulating guide rail 12, a circulating belt (not shown) connected to the slider 13, a collection hopper 14 located below the circulating guide rail 12, and a baffle 15 located on one side of the frame 11. The slider 13 is used to carry and connect the hoisting assembly 20.

[0030] Specifically, the paint booth 10 is located within a closed production workshop, and the paint booth 10 is a workstation within the entire production workshop. The circulating guide rail 12 shown in the drawings of this embodiment is only a portion of the entire circulating guide rail, which is arranged as a closed curve to achieve circular operation. Among them, a circulating belt is arranged along the route of the circulating guide rail 12 to drive the hoisting assembly 20 for processing between different workstations. This circulation structure is a common technology in the industrial field and will not be described in detail in this embodiment.

[0031] Furthermore, in this embodiment, the height of the baffle 15 is consistent with the height of the frame 11, and the top end of the baffle 15 is bent and extended toward the circulation guide rail 12, which can effectively prevent the paint from spraying outward.

[0032] The lifting assembly 20 includes a support plate 21 for connecting to the slider 13, telescopic cylinders 22 evenly spaced apart on one side of the support plate 21, movable plates 23 located on the other side of the support plate 21, and suction cups 24 mounted on each movable plate 23. The suction cups 24 are used to hold the plate 40. Each telescopic cylinder 22 is independently controlled. The piston rod of each telescopic cylinder 22 passes through the support plate 21 and connects to the movable plates 23, creating a one-to-one correspondence between the telescopic cylinders 22 and the movable plates 23.

[0033] In this embodiment, the movable plate 23 and the suction cup 24 are all located on the side of the carrier plate 21 facing away from the baffle 15. When spraying paint, the movable plate 23, the suction cup 24 and the plate 40 all stay above the collecting hopper 14 so that the collecting hopper 14 can collect the falling paint.

[0034] The paint spraying assembly 30 comprises a linear lift module 31, an adjustable support rod 32 connected to the slide of the linear lift module 31, and a spray head 33 mounted at the end of the adjustable support rod 32. The spray head 33 is positioned toward the baffle 15, with the sheet 40 positioned between the spray head 33 and the baffle 15 for spraying. During painting, the telescopic cylinder 22 is retracted to adjust the distance between the movable plate 23 and the spray head 33, and thus the distance between the sheet 40 and the spray head 33. This controls the spraying distance, effectively improving the uniformity of the paint spraying and ensuring the aesthetic appearance and service life of the paint layer.

[0035] Specifically, in this embodiment, the adjustable support rod 32 includes a fixed section 321 that secures the slide of the linear lift module 31, a first free section 322 rotatably connected to the end of the fixed section 321, and a second free section 323 rotatably connected to the end of the first free section 322. The end of the second free section 323 is hingedly connected to the spray head 33. The rotatable connection between the first free section 322, the second free section 323, and the spray head 33 enables the spray head 33 to be adjusted at multiple angles to meet different painting requirements.

[0036] The above-mentioned dust-free electrostatic paint circulation device has a simple structure and is easy to use. The telescopic cylinder 22 is connected to the movable plate 23. The suction cup 24 on the movable plate 23 is used to adsorb the plate 40. The distance between the plate 40 and the nozzle 33 can be easily adjusted to control the paint spraying distance, effectively improve the uniformity of the paint spraying, and ensure the surface beauty and service life of the paint layer.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
