Description

Technical Field

[0001] This utility model relates to the field of painting equipment technology, specifically a wood painting device. Background Technology

[0002] A wood panel painting device is an industrial piece of equipment used for semi-automatic painting of wood panel surfaces. It integrates processes such as spraying, spreading, and drying by replacing manual operation with mechanical structures. Its core objective is to improve painting efficiency, uniformity, and environmental friendliness, making it suitable for furniture manufacturing, building materials processing, and other fields.

[0003] The main working principle is that the wooden board is fed into the painting area at a constant speed by the conveyor belt, and the spray gun on the top slide rail sprays the atomized paint evenly onto the board surface by moving back and forth; immediately after spraying, the high-speed rotating nylon roller brush rolls close to the paint surface, scrapes off the excess paint and eliminates bubbles and brush marks; the treated wooden board is moved to the drying area to quickly cure the paint film and achieve the painting of the wooden board.

[0004] There is a paint box in a wood painting device. Due to external factors, there are local temperature differences in the paint box, which results in weak paint flow and inconsistent paint viscosity. This leads to uneven paint layer thickness during painting, causing defects such as drips and orange peel, which affect the surface quality of the wood.

[0005] Therefore, a wood painting device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] Preferably, the vent pipe is fitted with a jacket inside the paint tank; the jacket encloses the vent pipe; the jacket contains heat-conducting oil; the heat-conducting oil inside the jacket controls the paint temperature inside the paint tank; this reduces air bubbles and impurities in the paint, resulting in a smoother and more uniform paint layer. Simultaneously, the heated paint can better penetrate the wood surface, enhancing adhesion and improving coating quality.

[0009] Preferably, a connecting box is fixedly connected to one end of the vent pipe; an air outlet box is fixedly connected to the end of the connecting box; a diffuser is provided inside the air outlet box; the diffuser inside the air outlet box allows the hot air emitted by the hot air blower to be evenly dispersed, dissipating heat evenly on the painted wood board, and accelerating the drying and curing process of the paint layer.

[0010] Preferably, a collection plate is installed in the middle of the workbench; a support column is fixed to the bottom of the collection plate; a guide plate is fixed to the surface of the collection plate; excess paint is collected by the collection plate, and the guide plate guides the concentrated flow of paint, which can guide the paint to have fluidity, circulate and prevent sedimentation.

[0011] Preferably, a paint box is installed at the bottom of one side of the workbench; by installing a paint box on the device, waste can be reduced and corrosion and clogging of the device can be prevented.

[0012] Preferably, a mesh screen is fixed to the top of the paint box; excess paint enters the paint box after being filtered through the mesh screen, and the collected waste paint is easier to pre-treat by filtration, sedimentation and other processes, and can be reused after removing impurities, thereby reducing the cost of waste paint disposal.

[0013] The advantages of this utility model are:

[0014] 1. The wood painting device of this utility model uses the contact between the wood board and the brush wheel to roll, so that the paint is evenly applied to the wood board; by starting the second motor and turning on the hot air fan, the paint tank is preheated through the air pipe, so that the viscosity of the heated paint is reduced and the fluidity is enhanced, making it easier to evenly paint the surface of the wood board by the brush wheel, reducing clogging or graininess during the painting process.

[0015] 2. The wood painting device of this utility model uses heat-conducting oil inside the jacket to control the paint temperature inside the paint tank; this reduces air bubbles and impurities in the paint, resulting in a smoother and more uniform paint layer. Simultaneously, the heated paint can better penetrate the surface of the wood board, enhancing adhesion and improving coating quality. Attached Figure Description

[0025] 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 scope of protection of the present utility model.

[0026] Specific implementation examples are given below.

[0027] like Figures 1 to 7As shown, the system includes a workbench 1; a roller conveyor 11 is installed at the middle of the workbench 1; a support frame 12 is fixedly connected to the top of the workbench 1; a paint tank 13 is fixedly installed in the middle of the support frame 12; a paint pipe 14 is fixedly connected to the bottom of the paint tank 13; a diversion pipe 15 is provided through the end of the paint pipe 14; perforated pipes 16 are sleeved at both ends of the diversion pipe 15; brush wheels 17 are sleeved on the perforated pipes 16; a hot air blower 18 is fixedly connected to the top of the support frame 12; and the hot air blower 18 is connected to a ventilation pipe 19. During operation, the wooden board is placed on the roller conveyor 11, the hot air blower 18 is started, and the paint tank 13 is preheated through the vent pipe 19. The valve of the paint pipe 14 is opened, allowing the paint to be transported through the paint pipe 14 to the distribution pipe 15. The distribution pipe 15 distributes the paint into the porous pipe 16 at both ends, and then discharges it onto the brush wheel 17. At this time, the wooden board is conveyed forward by the roller conveyor 11. When the wooden board comes into contact with the brush wheel 17, the wooden board drives the brush wheel 17 to roll, so that the paint is evenly applied to the wooden board. By starting the hot air blower 18 and preheating the paint tank 13 through the vent pipe 19, the viscosity of the heated paint is reduced and its fluidity is enhanced, making it easier to evenly paint the wooden board surface through the brush wheel 17 and reducing clogging or graininess during the painting process.

[0028] like Figure 4 As shown, the vent pipe 19 is fitted with a jacket 2 inside the paint tank 13; the jacket 2 encloses the vent pipe 19; the jacket 2 contains heat-conducting oil 21; during operation, the vent pipe 19 preheats the inside of the paint tank 13, and the heat-conducting oil 21 inside the jacket 2 controls the stability of the paint inside the tank, thus stabilizing the paint state; by starting the hot air blower 18, the vent pipe 19 preheats the inside of the paint tank 13, causing the temperature inside the paint tank 13 to rise, but it is necessary to control the heating temperature to achieve the best effect. At this time, the heat-conducting oil 21 inside the jacket 2 controls the paint temperature inside the paint tank 13; this can reduce bubbles and impurities in the paint, making the paint layer smoother and more uniform; at the same time, the jacket 2 can isolate the paint from contact with the vent pipe 19, avoiding foreign matter contamination of the paint and adhesion and corrosion of the vent pipe 19.

[0029] like Figures 3 to 4 As shown, a connecting box 3 is fixedly connected to one end of the vent pipe 19; an air outlet box 31 is fixedly connected to the end of the connecting box 3; a diffuser 32 is provided inside the air outlet box 31; during operation, the hot air blower 18 blows hot air through the vent pipe 19 to the other end of the vent pipe 19; the hot air is diffused through the diffuser 32 inside the air outlet box 31, so that the hot air emitted by the hot air blower 18 is evenly dispersed, and the painted wood board is evenly cooled, accelerating the drying and curing process of the paint layer.

[0030] like Figure 5As shown, a collection plate 4 is installed in the middle of the workbench 1; a support column 42 is fixed to the bottom of the collection plate 4; a guide plate 41 is fixed to the surface of the collection plate 4; during operation, when the brush wheel 17 paints the wooden board, some excess paint will fall off. At this time, the excess paint falls onto the collection plate 4, and the guide plate 41 guides the direction of the fluid; by collecting the excess paint through the collection plate 4, and guiding the concentrated flow of paint through the guide plate 41, the paint can be guided to have fluidity, circulate, and prevent sedimentation.

[0031] like Figures 2 to 6 As shown, a paint box 5 is installed at the bottom of one side of the workbench 1; during operation, the paint on the collection plate 4 is collected into the paint box 5. By installing the paint box 5 on the device, waste can be reduced and corrosion and blockage of the device can be prevented.

[0032] like Figure 6 As shown, a mesh screen 6 is fixed to the top of the paint box 5; excess paint falls through the mesh screen 6 and enters the paint box 5; after being filtered through the mesh screen 6, the excess paint enters the paint box 5. The waste paint collected in a centralized manner is easier to filter, settle and other pre-treatments, remove impurities and then be remixed and reused, reducing the cost of waste paint disposal.

[0033] Working principle: During operation, the wooden board is placed on the roller conveyor 11, the hot air blower 18 is started, and the paint tank 13 is preheated through the vent pipe 19. The valve of the paint pipe 14 is opened, and the paint is transported through the paint pipe 14 to the distribution pipe 15. The distribution pipe 15 distributes the paint into the porous pipe 16 at both ends, and then discharges it onto the brush wheel 17. At this time, the wooden board is conveyed forward by the roller conveyor 11. When the wooden board comes into contact with the brush wheel 17, the wooden board drives the brush wheel 17 to roll, so that the paint is evenly applied to the wooden board. The vent pipe 19 preheats the inside of the paint tank 13. At this time, the paint is transported through the jacket 2. The internal heat transfer oil 21 stabilizes the paint inside the control box, maintaining a stable paint condition. By starting the hot air blower 18, the paint tank 13 is preheated via the vent pipe 19, raising its internal temperature. However, the heating temperature needs to be controlled for optimal effect. At this time, the jacket 2 contains heat transfer oil 21 to control the paint temperature inside the paint tank 13. The hot air blower 18 blows hot air through the vent pipe 19 to the other end of the vent pipe 19. The hot air is diffused by the diffuser 32 inside the air outlet box 31. Excess paint falls off the brush wheel 17 while painting the wooden board, landing on the collection plate 4. The guide plate 41 then guides the flow. The excess paint is collected by the collection plate 4, and the guide plate 41 directs the concentrated paint flow. The paint on the collection plate 4 converges into the paint box 5, while the excess paint falls through the strainer 6 and enters the paint box 5.
