Description

Technical Field

[0001] This utility model relates to the technical field of wooden door production equipment, and in particular to a wooden door surface spraying device that can spray paint evenly. Background Technology

[0002] As a common home furnishing product, wooden doors require painting as a crucial step in the production process to improve their appearance and durability. Painting not only enhances the appearance of wooden doors but also provides a protective layer to prevent them from being eroded by environmental factors. The quality of the paint spraying directly affects the visual effect and lifespan of the final product. Therefore, uniformity of the paint spraying is a critical aspect of the production process.

[0003] When using existing spray painting equipment to paint wooden doors, most of these systems cannot effectively clean the dust adhering to the doors. As a result, when dust particles adhere to the wooden doors during spray painting, the surface of the painted doors will have a grainy texture, which significantly affects the quality of the doors. In addition, when the factory is on lunch break, the spray painting equipment will stop spraying. At this time, the paint inside is in a non-flowing state, which can cause the paint to coagulate into particles if left for too long, thus affecting the uniformity of the paint spraying.

[0004] Therefore, those skilled in the art have provided a painting device for uniformly spraying paint on wooden door surfaces to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform paint spraying device for wooden doors. This device utilizes an anti-condensation mechanism, where a drive motor rotates a threaded rod, causing a threaded block to move. This movement, in turn, moves a movable frame, which in turn moves a drive shaft. The drive shaft, through gear engagement with a toothed plate, rotates, causing the aluminum strip mixing frame to rotate. This agitates the paint inside, preventing the paint from solidifying and clumping due to prolonged stagnation, thus ensuring uniform paint application.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A uniformly sprayed paint device for wooden doors includes a support frame. A cleaning mechanism is provided at the middle of the upper end of the support frame. The cleaning mechanism includes a cleaning frame fixedly connected to the upper surface of the support frame. A plurality of pressure rods are fixedly connected to the inner top surface of the cleaning frame. Pressure seats are fixedly connected to the lower surface of the pressure rods. Squeezing plates slide on the inner wall of the pressure seats. A damping spring is fixedly connected to the center of the upper surface of the squeezing plate. A cleaning plate is fixedly connected to the lower surface of the squeezing plate. Side plates are fixedly connected to both sides of the middle of the lower surface of the cleaning plate. Electrostatic adsorption rollers are rotatably connected to the rear end of the inner wall of the side plates.

[0008] A paint spray box is fixedly connected to the rear end of the upper surface of the support frame. An anti-condensation mechanism is provided at the upper end of the paint spray box. The anti-condensation mechanism includes a storage box fixedly connected to the paint spray box. A drive frame is fixedly connected to the upper surface of the storage box. A drive motor is fixedly connected to the outer wall of the rear end of the drive frame. The output end of the drive motor passes through the interior of the drive frame and is fixedly connected to a threaded rod. A threaded block is threadedly connected to the rod body. A movable frame is fixedly connected to the lower surface of the threaded block. A drive shaft is rotatably connected to the inner walls of both sides of the movable frame. Multiple aluminum strip hybrid frames are fixedly connected to the shaft body of the drive shaft. One end of the drive shaft passes through the movable frame and is fixedly connected to a gear. A toothed plate is fixedly connected to one inner wall of the storage box. A conveying mechanism is provided inside the support frame.

[0009] The above technical solution effectively improves the effect and uniformity of paint spraying on wooden doors through the cleaning mechanism, and effectively prevents the paint from solidifying into small particles when it is not used for a relatively long period of time.

[0010] Furthermore, the conveying mechanism includes multiple synchronous pulleys rotatably connected to the inner walls on both sides of the support frame. Each synchronous pulley is fitted with a synchronous belt on its outer wall, and multiple steel bars are fixedly connected to the outer wall of each synchronous belt. A servo motor is fixedly connected to the rear end of one side of the outer wall of the support frame, and the output end of the servo motor passes through the support frame and is fixedly connected to the synchronous pulley on the rear side.

[0011] The above technical solution uses a servo motor to drive a synchronous pulley to rotate, which in turn drives multiple steel bars to move synchronously via a synchronous belt.

[0012] Furthermore, each of the synchronous pulleys has a connecting shaft fixedly connected to the outer wall of the side where they are close to each other;

[0013] The above technical solution effectively enables both synchronous pulleys on both sides to rotate through the connecting shaft, thus avoiding the problem of excessive tooth load on the synchronous belt.

[0014] Furthermore, a through groove is provided at the front end of the upper surface of the spray box, a delivery pump is fixedly connected to the middle of the upper surface of the spray box near the front end, an electric slide rail is fixedly connected to the inner top surface of the spray box, an electric slider slides inside the electric slide rail, and an atomizing sprayer is fixedly connected to the lower surface of the electric slider.

[0015] The above technical solution uses an electric slide rail to move the Sames Kremlin AUTO20 atomizing sprayer laterally, thus overcoming the problem of manual movement of this model of atomizing sprayer.

[0016] Furthermore, the input end of the delivery pump is connected to the storage tank, the output end of the delivery pump passes through the through groove and is threadedly connected to a bellows, and the lower end of the bellows is connected to the atomizing sprayer.

[0017] The above technical solution allows for easier disassembly of the bellows with threaded connection to the output end of the delivery pump for cleaning and maintenance. Furthermore, by connecting it to the atomizing paint sprayer, the length can be adaptively adjusted to suit the needs of the sprayer's movement.

[0018] Furthermore, arc-shaped wheels are fixedly connected to both sides of the front end of the lower surface of the cleaning plate, and support wheels are fixedly connected to both sides of the rear end of the lower surface of the cleaning plate.

[0019] Through the above technical solution, the arc-shaped wheels can effectively adjust the height of the cleaning mechanism according to the thickness of the wooden door.

[0020] Furthermore, an electric motor is fixedly connected to the front end of one outer wall of the side plate, and the output end of the electric motor passes through the side plate and is fixedly connected to a brush roller. The outer wall of the brush roller away from the electric motor is rotatably connected to the inner wall of the other side plate.

[0021] The above technical solution uses an electric motor to drive the brush roller to rotate at high speed, which causes the soft bristles of the brush roller to be thrown out by centrifugal force, thereby impacting the surface of the wooden door. This effectively breaks up stubborn dust particles, making it easier for the electrostatic adsorption roller to adsorb dust.

[0022] Furthermore, an electrostatic generator is fixedly connected to the middle of the upper surface of the cleaning plate, and the electrostatic generator is electrically connected to the electrostatic adsorption roller.

[0023] The above technical solution utilizes a Trek 610E electrostatic generator to effectively generate an electrostatic field force on the electrostatic adsorption roller, thereby adsorbing dust particles.

[0024] Furthermore, support seats are fixedly connected to both sides of the lower surface of the support frame;

[0025] The above technical solution provides a more effective support for lifting the equipment by using the support base.

[0026] Furthermore, a filling pipe is connected through one side of the upper surface of the storage box;

[0027] The above technical solution makes it easier to replenish paint into the storage tank.

[0028] This utility model has the following beneficial effects:

[0029] 1. The present invention proposes a painting device for uniformly spraying paint on wooden door surfaces. Through a cleaning mechanism, the cleaning plate is raised by the wooden door, and then the electrostatic adsorption roller is brought into contact with and rotated on the upper surface of the wooden door, thereby adsorbing the dust particles attached to the upper surface of the wooden door, thus avoiding the problem of dust particles on the wooden door surface affecting the texture after painting.

[0030] 2. The present invention proposes a wood door surface painting device for uniform spraying. By setting an anti-condensation mechanism, a drive motor drives a threaded rod to rotate, thereby moving a threaded block, which in turn moves a movable frame. The movable frame then moves a drive shaft, which in turn rotates the drive shaft through gear meshing with a toothed plate. This drive shaft then rotates the aluminum strip mixing frame, thereby agitating the paint inside. This avoids the problem of paint solidifying and clumping due to prolonged lack of flow, which affects the uniformity of spraying. Attached Figure Description

A filling pipe 502 is connected through one side of the upper surface of the storage box 501, so that paint can be added to the inside of the storage box 501 more conveniently.

[0060] Working principle: In use, the wooden door is placed onto the conveyor mechanism 6 from the front end. Then, the servo motor 601 is started, causing one of the synchronous pulleys 602 to rotate. The synchronous belt 604, in conjunction with the connecting shaft 603, rotates all the synchronous pulleys 602. The steel bar 605 then supports the wooden door, moving it to the lower end of the cleaning mechanism 4. The curved wheel 404 first contacts the wooden door, and the thickness of the door compresses the curved wheel 404, causing it to move upwards. This allows the curved wheel 404 to press against the cleaning plate 409. The cleaning plate 409 then presses against the damping spring 413 via the pressing plate 412 and slides on the pressure seat 402. The damping spring 413 is then compressed by the pressure seat 402, which in turn provides a downward force to the cleaning plate 409, causing the arc wheel 404 to make close contact with the wooden door surface. The electric motor 411 is then activated, driving the brush roller 406 to rotate at high speed. The centrifugal force of the rotating brush roller 406 causes the soft bristles to break up stubborn dust on the wooden door surface. The dust is then absorbed by the electrostatic adsorption roller 407, which in turn adsorbs the dust. The wooden door is then conveyed by the conveying mechanism 6 and flows into the paint spray box 2. The paint is then drawn from the storage tank 501 by the conveying pump 505 and transported to the corrugated pipe 503, flowing into the Sames. The Kremlin AUTO 20 type atomizing spray paint sprayer 8 is moved inside the electric slide rail 7 by the electric slider 9, thereby spraying the wooden door. When spraying is paused, the drive motor 507 starts, which drives the threaded rod 512 to rotate. The rotation of the threaded rod 512 causes the threaded block 508 to move, which in turn drives the movable frame 509 to move. The movable frame 509 then drives the drive shaft 510 to move. The drive shaft 510 then drives the gear 514 to mesh with the toothed plate 513, which in turn drives the drive shaft 510 to rotate. The drive shaft 510 then drives the aluminum strip mixing frame 511 to rotate, thereby stirring the paint in the storage box 501 and making it flow. After the wooden door is painted, it flows out of the lower end of the spray paint box 2 through the conveying mechanism 6 and enters the next process.
