Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, specifically a furniture board spray painting and drying device. Background Technology

[0002] Furniture boards come in a variety of materials, including solid wood, engineered wood, engineered wood, steel-wood composite, MDF, particleboard, blockboard, plywood, decorative panels, bamboo-scented boards, and more. Typically, these boards are made into standard-sized, flat rectangular panels and then painted to achieve aesthetic appeal, moisture resistance, and insect prevention.

[0003] A search revealed that application number CN202320891546.5 discloses a board painting drying device, including a box body, a second shell fixed to the bottom of the box body, a groove on the top of the box body, a first shell slidably connected inside the groove, air inlets at the bottom of both the first and second shells, T-shaped pipes fixedly installed on the top of both the first and second shells, and sliding grooves on both sides of the inner wall of the box body below the T-shaped pipes, with moving mechanisms installed inside both sliding grooves. By fixing T-shaped pipes to the top and bottom of the board body, the paint drying is accelerated, which helps to improve processing speed and production efficiency.

[0004] Existing spray painting drying equipment uses clamps to fix and transport the boards. Since the boards need to be sprayed with paint evenly on both sides before drying, the clamping part will affect the spraying effect due to obstruction. At the same time, the boards are only dried by hot air from one or both sides, which can easily cause deformation or even cracking of the boards due to uneven heating, affecting the appearance of the finished product. Utility Model Content

[0005] The purpose of this utility model is to provide a furniture board spray painting and drying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a furniture board spray painting and drying device, including a device body, an adjustment component installed at the bottom of the inner cavity of the device body, a drying component fixedly connected to the middle of the inner cavity of the device body, the drying component being arranged perpendicular to the conveying direction, two sets of conveying components symmetrically installed in the inner cavity of the device body, the two sets of conveying components being arranged along the conveying direction passing through the middle area of ​​the drying component, and the adjustment component driving the two sets of conveying components to move closer or further away from each other to adjust the distance between adjacent parts of the two sets of conveying components;

[0007] The conveying assembly includes a transmission belt, two sets of adjusting rollers and driven rollers arranged parallel to each other along the conveying direction, a drive motor, and a drive wheel arranged parallel to the driven rollers along the conveying direction. The drive motor drives the drive wheel to rotate, and the drive wheel is connected to the two sets of adjusting rollers and driven rollers in sequence through the transmission belt.

[0008] As a further preferred embodiment, the main body of the device includes a box, with a discharge port and a feed port respectively opened at the front and rear ends of the box. Two sets of sliding grooves are spaced apart at the bottom of the inner cavity of the box in the vertical conveying direction, and a limit rod is fixedly connected in one set of the sliding grooves.

[0009] As a further preferred embodiment, the adjustment assembly includes an adjustment motor installed on the side wall of the housing, the conveying end of the adjustment motor being fixedly connected to a bidirectional lead screw through the side wall of the housing, and the end of the bidirectional lead screw opposite to the adjustment motor being rotatably connected to the inner wall of another set of slide grooves.

[0010] As a further preferred embodiment, the drying assembly includes a hot air blower installed on the side wall of the housing, the air outlet of the hot air blower extending into the inner cavity of the housing and fixedly connected to a frame-shaped air supply pipe, and the frame-shaped air supply pipe and the conveying assembly are provided with several sets of air outlets spaced apart on the side adjacent to each other.

[0011] As a further preferred embodiment, the two sets of adjusting rollers are rotatably connected by mounting shafts. One set of mounting shafts has a limit block fixedly connected to its lower end, and the limit block is slidably connected to the outer wall of the limit rod. The other set of mounting shafts has a slider fixedly connected to its lower end, and the slider is threadedly connected to the outer wall of the bidirectional lead screw.

[0012] As a further preferred embodiment, the two sets of outer wall mounting shafts are fixedly connected by connecting rods, and two sets of limiting slide grooves are provided at the top of the inner cavity of the box perpendicular to the two sets of slide grooves, and the tops of the two sets of mounting shafts are respectively slidably connected to the limiting slide grooves.

[0013] Through the above technical solution, the furniture board spray painting and drying device provided by this utility model has the following advantages:

[0014] This utility model features a conveying assembly with two symmetrically arranged components. A drive motor drives the drive wheel to rotate, which in turn transmits power to two sets of adjusting rollers and driven rollers via a transmission belt. The outer wall of the transmission belt contacts the side wall of the sheet material to clamp it. The continuous transmission belt then conveys the sheet material, which is then sequentially sprayed and dried inside the frame-shaped air duct. This design avoids incomplete paint coverage caused by the clamping components being fixed to the paint surface during spraying and drying.

[0015] Meanwhile, by adjusting the motor driven by the set adjustment components, the rotating bidirectional lead screw drives the two sets of sliders on its outer wall to move closer or further apart, thereby clamping and fixing plates of different widths and improving the applicability of the device.

[0016] Moreover, the drying component is frame-shaped, covering the area around the board, and blows air to dry the board in a direction perpendicular to the board, which improves drying efficiency and avoids deformation of the board due to uneven heating. Attached Figure Description

[0024] 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.

[0025] The present invention will be further described in detail with reference to the accompanying drawings.

[0026] Please see Figure 1 - Figure 6 The present invention provides a furniture board spray painting and drying device, which includes a device body 1, an adjustment component 2, a drying component 3 and a conveying component 4.

[0027] Please see Figures 1 to 3The main body 1 of the device includes a box 12, with a discharge port 11 and a feed port 13 at the front and rear ends of the box 12, respectively. Two sets of sliding grooves 14 are spaced apart at the bottom of the inner cavity of the box 12 in the vertical conveying direction. A limit rod 15 is fixedly connected in one set of sliding grooves 14. The adjustment component 2 includes an adjustment motor 21 installed on the side wall of the box 12. The output end of the adjustment motor 21 extends into the inner cavity of the box 12 and is fixedly connected to a bidirectional lead screw 22. The bidirectional lead screw 22 is rotatably connected in the other set of sliding grooves 14. The drying component 3 is set in the middle of the inner cavity of the box 12 and performs hot air drying on the board material passing through the drying component 3. The conveying component 4 is symmetrically arranged in the inner cavity of the box 12 along the conveying direction. By adjusting the distance between the two sets of sliding grooves 14, the side wall of the board material is clamped and fixed, thereby conveying the board material from the feed port 13 to the discharge port 11.

[0028] It should be added that a painting assembly is installed in the inner cavity of the box 12 near the feed port 13. The painting assembly is symmetrically arranged along the horizontal surface of the board and can paint the upper and lower surfaces of the board at the same time.

[0029] Please see Figure 4 The drying assembly 3 includes a hot air blower 31 installed on the side wall of the housing 12. The outlet of the hot air blower 31 is fixedly connected to a frame-shaped air duct 32 through the side wall of the housing 12. During the conveying process, the board moves through the middle of the frame-shaped air duct 32. The frame-shaped air duct 32 is provided with several sets of air outlets 33 at intervals on the side adjacent to the board. The hot air blower 31 delivers hot air to the plane perpendicular to the board through the air outlets 33, and then performs synchronous hot air drying on the four sides of the board through the air outlets 33, thereby improving the drying uniformity of the board.

[0030] Please see Figure 5 and Figure 6 The conveying assembly 4 includes a drive motor 47 installed in the inner cavity of the housing 12, two sets of adjusting rollers 42 arranged along the conveying direction, and a driven roller 44 installed along the conveying direction with the drive motor 47. The output end of the drive motor 47 is fixedly connected to a drive wheel 48, and the drive wheel 48 is externally connected to a transmission belt 41. The drive wheel 48 is sequentially connected to the two sets of adjusting rollers 42 and the driven roller 44 through the transmission belt 41. The axis of the adjusting roller 42 is rotatably connected to a mounting shaft 43. The upper end of the mounting shaft 43 is slidably connected to the top of the inner cavity of the housing 12. The lower end of one set of mounting shafts 43 is fixedly connected to a limit block 45, which is slidably connected to the outer wall of the limit rod 15. The lower end of the other set of mounting shafts 43 is fixedly connected to a slider 46, which is threadedly connected to the outer wall of the bidirectional lead screw 22. The top of each mounting shaft 43 is slidably connected to the top of the inner cavity of the housing 12.

[0031] Specifically, the outer wall of the transmission belt 41 is provided with several sets of anti-slip grooves 49 spaced apart along the conveying direction to improve the friction between the transmission belt 41 and the side wall of the plate.

[0032] It should be noted that the driven roller 44 is slidably connected to the bottom of the inner cavity of the housing 12 via the mounting shaft, and moves along the conveying direction at the bottom of the inner cavity of the housing 12 as the adjusting roller 42 moves. The mounting shaft is connected to the side wall of the housing 12 via an elastic component, which restricts the position of the mounting shaft, provides support for the adjusting roller 42, and avoids the transmission belt 41 from being too tight when the adjusting roller 42 is adjusted, thus affecting the movement range of the adjusting roller 42.

[0033] It should also be noted that the two sets of conveying components 4 are symmetrically arranged, and the two sets of sliders 46 are respectively sleeved on the bidirectional threaded part of the bidirectional lead screw 22. The adjusting motor 21 drives the bidirectional lead screw 22 to rotate, and the two sets of sliders 46 are threadedly engaged with the bidirectional lead screw 22 so that they move closer or further apart from each other.

[0034] It should be added that the outer walls of the two sets of mounting shafts 43 located in the same set of conveying components 4 are fixedly connected with connecting rods. When the slider 46 moves, the two sets of adjusting rollers 42 can move synchronously by being limited by the connecting rods.

[0035] It should also be noted that a limiting groove is provided on the top of the housing 12, and the upper end of the mounting shaft 43 is slidably connected in the limiting groove to improve the stability of the movement of the adjusting roller 42 and the support strength for the plate.

[0036] It is understandable that the transmission belts 41 driven by the outer walls of the two sets of adjusting rollers 42 arranged along the conveying direction and the symmetrically arranged transmission belts 41 clamp the side walls of the plate respectively, thereby realizing the fixing and conveying of the plate.

[0037] Principle: The sheet material is extended horizontally from the feed inlet 13 into the inner cavity of the housing 12. The adjusting motor 21 drives the bidirectional lead screw 22 to rotate, causing the two sets of sliders 46 to move closer to each other. The sliders 46 drive the mounting shaft 43, which in turn drives the mounting shaft 43 to move in the same direction via the connecting rod. The side wall of the sheet material is clamped by adjusting the distance of the adjusting rollers 42 of the symmetrical group. The clamped sheet material moves along the conveyor belt 41 in the conveying direction. After being painted by the painting assembly, it passes through the inner area of ​​the frame-shaped air duct 32 and is dried by the hot air sprayed from the air outlet 33. The dried sheet material is then conveyed to the discharge port 11, completing the painting and drying of the sheet material.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
