Description

Technical Field

[0001] This utility model relates to the technical field of automatic topcoat spraying machines, and in particular to an automatic topcoat spraying machine for cabinet production. Background Technology

[0002] An automatic topcoat spraying machine is a device capable of automatically completing the topcoat spraying operation on the surface of an object. Announcement No.: CN218637747U. This utility model discloses an automatic topcoat spraying machine for cabinet production, relating to the technical field of cabinet production equipment. The utility model includes a base, a rolling element, a recovery tray, and a spray box. The rolling element is installed inside the base, and the recovery tray is embedded in the outer walls of the front and rear sides of the base. The other side wall of the recovery tray is connected to a guide pipe, and the other side wall of the guide pipe is connected to the spray box. Cabinet wood panels are placed in the upper side wall of the rolling element. A liquid collection box is embedded in the bottom side wall of the spray box, and the liquid collection box is connected to a spray plate via a hanging rod. The internal chamber of the liquid collection box is connected to the spray plate via a flexible hose. This invention utilizes a collection box to transport paint to a spray plate, allowing for uniform painting of the entire cabinet board in one pass. The collected paint is guided into a spray tank via a guide pipe, effectively conserving paint resources. A fan within the collection tray provides directional suction. However, in practical applications, there are some shortcomings. The atomization of ordinary spray plates is not fine enough, resulting in excessive paint atomization in some areas after painting. This excess paint can cause dripping and sagging under gravity, damaging surface smoothness and potentially requiring additional sanding and repair processes. Improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: an automatic topcoat spraying machine for cabinet production, including a shell, a paint discharge groove is provided on the lower surface of the shell, the paint discharge groove is connected to a collection tray, one end of the collection tray is connected to a guide pipe, one end of the guide pipe is connected to a paint storage box, a cover plate is fitted on the upper surface of the paint storage box, a flexible tube is connected to the lower surface of the paint storage box, the flexible tube is connected to a paint receiving box, a nozzle is connected to the lower surface of the paint receiving box, a spray nozzle is provided on the surface of the nozzle, a baffle is rotatably connected to the surface of the nozzle, and an oblique spray nozzle is provided on the surface of the baffle.

[0005] Preferably, a connecting rod is fixedly installed between the paint storage box and the paint receiving box. There are two sets of connecting rods, symmetrically distributed on both sides of the hose. Here, the connecting rods secure the paint receiving box and the paint storage box together, preventing the paint receiving box from falling off. Using two sets of connecting rods also helps to better balance the force.

[0006] Preferably, a bearing is fixedly installed between the baffle and the paint receiving box. Here, the bearing reduces the friction force experienced by the baffle when it rotates on the nozzle surface, making the rotation of the baffle smoother and the paint atomization more uniform.

[0007] Preferably, the number of nozzles and baffles is three sets, which are equidistantly distributed on the surface of the paint receiving box. Using three sets of nozzles and baffles allows for spraying paint onto the object surface from different positions, resulting in a more uniform paint coverage and reducing problems such as missed areas, runs, and uneven thickness. This also compensates for the uneven spraying of a single nozzle at certain angles or areas, ensuring the smoothness and evenness of the coating.

[0008] Preferably, the bottom surface of the outer casing is a sloped base plate, and the upper surface of the base plate is aligned with the lower surface of the paint drain trough. Here, using a sloped base plate allows the paint accumulated on the base plate to flow more quickly into the recovery tray, enter the guide pipe, and flow back to the paint storage box, thus enabling faster paint reuse and reducing waste.

[0009] Preferably, a lead screw is rotatably connected inside the housing, with opposite thread directions at both ends of the lead screw. Limiting blocks are threadedly connected to both ends of the lead screw, and a turntable is fixedly mounted at one end of the lead screw. Here, rotating the turntable quickly drives the lead screw to rotate. Utilizing the opposite threads at both ends of the lead screw, the two limiting blocks move in opposite directions along the lead screw, achieving rapid positioning and clamping of cabinet components of different sizes. This allows for adaptation to various workpiece specifications without complex operations, improving production efficiency. The lead screw drive has a self-locking characteristic, ensuring the limiting blocks remain stable after the lead screw is positioned, preventing position changes due to external forces, vibrations, or other factors. This ensures that the cabinet components remain in a precise, fixed position during the painting process, guaranteeing the uniformity and accuracy of the paint application.

[0010] Preferably, a limiting plate is fixedly installed inside the housing, located on both sides of the limiting block, and a rubber sheet is fixedly installed on the surface of the limiting plate. Here, the limiting plate restricts the movement of the limiting block, ensuring linear movement of the limiting block on the lead screw. At the same time, the rubber sheet installed on the limiting plate prevents paint from spraying onto the surface of the lead screw.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting a baffle, nozzle and bearing structure, the paint sprayed from the nozzle is sprayed out in the oblique nozzle of the baffle, and at the same time the baffle rotates. The oblique nozzle and the nozzle cooperate to achieve more uniform atomization of the paint, and reduce the occurrence of excessive paint atomization in some areas after painting due to insufficient atomization of the paint.

[0013] 2. In this utility model, by setting a lead screw, a limiting block and a turntable structure, rotating the turntable drives the lead screw to rotate, and the lead screw drives the limiting block on the surface to move, thereby realizing the linear movement of the cabinet panel, preventing uneven painting caused by the tilt of the cabinet panel, and also keeping the cabinet panel directly below the nozzle for easy painting.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] Please see Figure 1-5 This utility model provides a technical solution: an automatic topcoat spraying machine for cabinet production, including a housing 1, with rollers 7 rotatably connected inside the housing 1. A paint discharge trough 8 is formed on the lower surface of the housing 1, connected to a collection tray 3. One end of the collection tray 3 is connected to a guide pipe 4, and the other end of the guide pipe 4 is connected to a paint storage box 5. A cover plate 6 is fitted onto the upper surface of the paint storage box 5, and a flexible hose 9 is connected to the lower surface of the paint storage box 5. The flexible hose 9 is connected to a paint receiving box 14. A connecting rod 10 is fixedly installed between the paint storage box 5 and the paint receiving box 14. There are two sets of connecting rods 10, symmetrically distributed on both sides of the flexible hose 9. The connecting rods 10 fix the paint receiving box 14 and the paint storage box 5 together, preventing the paint receiving box 14 from falling off. Using two sets of connecting rods 10 allows for support of the device from two different positions, distributing the weight of the device. Compared to a single connecting rod 10, this better maintains the balance and stability of the device, reducing the risk of tilting due to external forces. To mitigate the risk of tilting or wobbling, and to ensure the device remains in its predetermined position during operation or rest, a nozzle 13 is connected to the lower surface of the paint receiving box 14. The nozzle 13 has an opening 15 on its surface, and a baffle 11 is rotatably connected to its surface. The baffle 11 has an angled opening 16 on its surface. There are three sets of nozzles 13 and baffles 11, equidistantly distributed on the surface of the paint receiving box 14. Using these three sets of nozzles 13 and baffles 11 allows for painting of the object's surface from different positions, resulting in a more even paint coverage and reducing issues such as missed areas, runs, and uneven thickness. This compensates for the uneven spraying of a single nozzle 13 at certain angles or areas, ensuring the smoothness and evenness of the coating. With three nozzles 13 working simultaneously, the paint coverage area per unit time is larger than with a single nozzle 13, enabling large-area painting tasks to be completed in a shorter time, effectively improving work efficiency and making it suitable for large-scale painting operations.

[0026] Example 2

[0027] Please see Figure 6The housing 1 has a lead screw 18 rotatably connected inside. The threads at both ends of the lead screw 18 are in opposite directions. Limiting blocks 19 are threadedly connected to both ends of the lead screw 18. A turntable 20 is fixedly installed at one end of the lead screw 18. By rotating the turntable 20, the lead screw 18 can be quickly driven to rotate. Utilizing the opposite threads at both ends of the lead screw 18, the two limiting blocks 19 move in opposite directions along the lead screw 18, achieving rapid positioning and clamping of cabinet parts of different sizes. It can adapt to various specifications of workpieces without complicated operations, improving production efficiency. The lead screw 18 transmission has a self-locking characteristic, and the limiting blocks 19 are located on the lead screw 18. After positioning, it can remain stable and is not easily changed by external forces, vibrations, or other factors. This ensures that the cabinet components are always in a precise fixed position during the painting process, guaranteeing the uniformity and accuracy of the paint spraying. A limiting plate 21 is fixedly installed inside the outer shell 1. The limiting plate 21 is located on both sides of the limiting block 19. A rubber sheet 22 is fixedly installed on the surface of the limiting plate 21. The limiting plate 21 can restrict the movement of the limiting block 19 to ensure that the limiting block 19 moves linearly on the lead screw 18. At the same time, the rubber sheet 22 installed on the limiting plate 21 prevents paint from spraying onto the surface of the lead screw 18.

[0028] Working principle: When using this device to paint a cabinet, start roller 7 to convey the cabinet panel to the area below nozzle 13. Rotate turntable 20 to rotate lead screw 18, which in turn moves the limiting block 19 on the surface of lead screw 18. The limiting block 19 restricts the cabinet panel directly below nozzle 13. Then, turn on booster pump 17 to pressurize the paint for spraying. When the paint passes through nozzle 15, it accelerates and is sprayed out from nozzle 15. The high-speed paint sprays out of the angled nozzle 16, which drives baffle 11 to rotate on bearing 12. The rotating baffle 11 divides the paint sprayed from nozzle 15 into small droplets, atomizing the paint. The atomized paint falls on the surface of the cabinet panel, while excess paint falls onto base plate 2. Small paint droplets gather into large paint droplets and flow down the slope into collection tray 3. The air pump in collection tray 3 carries the paint from guide pipe 4 into paint storage box 5 for reuse.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
