Description

Technical Field

[0001] This utility model relates to the field of wardrobe board processing technology, and in particular to a board painting device for home wardrobe production. Background Technology

[0002] During the production and processing of home wardrobes, the cabinet panels need to be painted to give them different colors and appearances. However, currently, the painting process for cabinet panels usually involves placing the panels on the spraying station, and then the worker holding a misting nozzle and moving around the panels to spray them. This is not only time-consuming and labor-intensive, but also makes it difficult to control the uniformity of the paint layer thickness.

[0003] To address these issues, we propose a panel painting device for home wardrobe production. Utility Model Content

[0004] The purpose of this utility model is to provide a panel painting device for home wardrobe production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A panel painting device for home wardrobe production includes a frame with a conveyor belt on it. Supports are symmetrically mounted on both sides of the frame, and a painting frame is mounted on each support. The painting frame includes a paint supply pipe with a connector at its end. Several connectors are arranged along the width of the conveyor belt, and adjacent connectors are connected by flexible hoses. Each connector has a bent pipe connected to its side, and an atomizing nozzle is mounted at the lower end of the bent pipe. A paint pump is connected to the head of the paint supply pipe, and a paint storage tank is located below the paint pump.

[0007] In a further embodiment, the bends connected to the two outermost joints are inclined toward the central axis of the conveyor belt.

[0008] In a further embodiment, the bend and the atomizing nozzle are connected by a thread.

[0009] In a further embodiment, a ring is fixed on the bend, and a screw sleeve is rotatably connected inside the ring. A screw rod is threaded through and connected to the screw sleeve, and both ends of the screw rod are fixed to the bracket.

[0010] In a further embodiment, a locking bolt is threaded onto the ring sleeve, and one end of the locking bolt extending into the ring sleeve is rotatably connected to a compression head.

[0011] In a further embodiment, the width of the conveyor belt is smaller than the width of the material to be processed.

[0012] In a further embodiment, guide rollers are provided at both ends of the inner side of the conveyor belt, and several rollers are provided between the two guide rollers in close contact with the inner top surface of the conveyor belt. Tensioning rollers are also provided in close contact with the inner bottom surface of the conveyor belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention automates the spraying process by placing the sheet material on a conveyor belt and having it move along with the belt, passing under a spraying gantry composed of multiple atomizing nozzles. This eliminates the inconvenience of manual spraying by workers, resulting in high spraying efficiency and improved uniformity of paint layer thickness. Furthermore, the position of the atomizing nozzles can be adjusted to accommodate sheet materials of different widths, making the entire device more flexible in use. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] 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.

[0024] Please see Figure 1-2 A painting device for furniture wardrobe production includes a frame 1 with a conveyor belt 2 mounted on it. Specifically, the width of the conveyor belt 2 is smaller than the width of the board to be processed, ensuring that the edges of the board are far from the surface of the conveyor belt 2 when placed on it, thus reducing paint spillage on the conveyor belt 2 during painting. Supports 3 are symmetrically mounted on both sides of the frame 1, each with an inverted L-shaped structure. A painting gate is mounted on the support 3, positioned directly above the conveyor belt 2. The painting gate includes a paint supply pipe 4, with a connector 5 at the end of the pipe and a paint pump 9 connected to the beginning. A paint storage tank 10 is located below the paint pump 9 to facilitate the transfer of paint. The paint pump 9 outputs the paint liquid in the paint storage tank 10 to the paint supply pipe 4. Several connectors 5 are arranged in a row along the width direction of the conveyor belt 2, and adjacent connectors 5 are connected by hoses 6. Each connector 5 has a bend 7 connected to its side, and an atomizing nozzle 8 is installed at the lower end of the bend 7. The paint liquid flows through the connectors 5, hoses 6 and bend 7, and is finally sprayed out from the atomizing nozzle 8, so that multiple atomizing nozzles 8 form a spray curtain, which facilitates the overall spraying of the width of the board when the board below passes by. Specifically, the bend 7 and the atomizing nozzle 8 are connected by threads, which makes it easy to disassemble and assemble. In order to prevent water leakage, a sealing ring is placed inside the screw interface between the bend 7 and the atomizing nozzle 8.

[0025] Furthermore, in order to facilitate thorough spraying of the sides of the board, the bends 7 connected to the two outermost connectors 5 are inclined towards the central axis of the conveyor belt 2, so as to facilitate spraying towards the sides of the board and make the paint surface on the sides of the board more uniform.

[0026] Please see Figure 3-4Considering that the position of the atomizing nozzle 8 needs to be adjusted when spraying boards of different widths, the nozzle gantry also includes a screw 13, and a screw sleeve 12 is threaded onto each bend 7 on the screw 13. A ring sleeve 11 is rotatably sleeved on the outside of the screw sleeve 12, and the ring sleeve 11 is fixedly connected to the bend 7. Specifically, the two ends of the screw sleeve 12 protrude from the ring sleeve 11 to facilitate the operator's turning and adjustment. A locking bolt 14 is threaded onto the ring sleeve 11. One end of the locking bolt 14, which extends into the ring sleeve 11, is rotatably connected to a pressing head 141. When the locking bolt 14 is tightened, the pressing head 141 is pressed against the outer wall of the screw sleeve 12, thereby locking the screw sleeve 12 and the ring sleeve 11, so that the ring sleeve 11 no longer rotates easily relative to the screw sleeve 12, maintaining the stability of the atomizing nozzle 8 during operation.

[0027] Please see Figure 5 To facilitate the transport of the sheet material, guide rollers 15 are provided at both ends of the conveyor belt 2. The two ends of the guide rollers 15 are rotatably connected to the frame 1, and one of the guide rollers 15 is also connected to a drive motor to drive the guide roller 15 to rotate. Between the two guide rollers 15, there are several rollers 16 that are close to the inner top surface of the conveyor belt 2. The rollers 16 are rotatably connected to the frame 1 to support the sheet material and prevent the upper part of the conveyor belt 2 from collapsing. Furthermore, tension rollers 17 are also closely attached to the inner bottom surface of the conveyor belt 2. The installation position of the tension rollers 17 relative to the frame 1 can be adjusted up and down to maintain the tension of the conveyor belt 2.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
