Description

Technical Field

[0001] The utility model relates to the technical field of wood door painting and drying equipment, in particular to a painting and drying device for solid wood door production. Background Technique

[0002] A solid wood door refers to a door made of natural logs or solid wood integrated materials taken from the forest. The commonly selected woods are precious woods, such as walnut, teak, red oak, ash, and sapelli, etc.

[0003] The finished door after processing has the characteristics of no deformation, corrosion resistance, no cracks, heat insulation and heat preservation, etc. After the wood door panels are batch processed, it is necessary to spray paint on the surface of the wood door panels to improve the aesthetics and surface performance of the door panels. And in order to improve the production efficiency of the wood door panels, after spraying, the paint surface will be dried to improve the drying efficiency of the paint surface.

[0004] Chinese Patent Publication No. CN217911182U discloses an efficient drying device for wood door panel painting, including a housing, a mounting frame and a cleaning tank. On both sides inside the housing, lead screws are installed through bearings. An adjusting block for vertical reciprocating movement is arranged around the lead screw. One side of the adjusting block is provided with a mounting frame. One side of the mounting frame is bolted with a wind guiding cylinder for drying. A cleaning tank is arranged on the top of the housing. The bottom of the housing is bolted with a return tank for circulating the drying operation, and the air outlet end of the return tank is located inside the housing. The back of the cleaning tank is communicated with the return tank through a pipeline. The utility model, an efficient drying device for wood door panel painting, has a simple structure, is easy to operate, is flexible and convenient to use, has high practical value, and is suitable for being widely promoted and used.

[0005] Through the lead screw, the adjusting block and the wind guiding cylinder, the above-mentioned patent can blow and dry the painting area while the nozzle is performing the painting operation. However, since the wind guiding cylinder moves along with the nozzle, the hot air discharged through the wind guiding cylinder blows vertically towards the paint surface after the nozzle passes. However, since the contact time between the paint and the wood door is short, when the hot air contacts the paint vertically, it is easy to push the paint to move, resulting in a poor flatness of the paint surface on the wood door.

Detailed implementation mode

[0028] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0029] Embodiment:

[0030] Refer to Figures 1 - 5 , a paint spraying and drying device for solid wood door production disclosed by the present utility model includes a base 1, a first housing 2 is arranged at the upper end of the base 1, a second housing 3 is rotatably connected to the outer wall of the first housing 2, a first drying hood 4 is arranged inside the first housing 2, a second drying hood 5 is arranged on the side wall of the first drying hood 4, and a door panel painting device 6 is arranged inside the first drying hood 4;

[0031] An extension plate 7 extends from the top end of the first drying hood 4, and a first diversion groove 8 is jointly opened on the side wall of the extension plate 7 and the first drying hood 4. A diversion pipe 9 is connected to the top end of the first drying hood 4. The diversion pipe 9 is communicated with the first diversion groove 8, and the diversion pipe 9 is connected to a hot air mechanism;

[0032] An insertion piece 10 is fixedly arranged at the top end of the second drying hood 5, and the insertion piece 10 corresponds to the position of the extension plate 7 and is inserted into the inside of the first diversion groove 8. A second diversion groove 11 is opened on the side wall of the second drying hood 5;

[0033] A plurality of air guide frames 12 are opened on the inner walls of the first drying hood 4 and the second drying hood 5.

[0034] In this embodiment, when in use, the wooden door panel to be painted is installed inside the door panel painting device 6, then the second drying hood 5 and the first drying hood 4 are connected, and then the second housing 3 is rotated to make the second housing 3 rotate to the opening of the first housing 2 to close the opening of the first housing 2, as Figure 1As shown in the figure, the door panel to be painted is installed inside the door panel painting device 6 at this time, and the door panel is inside the cylinder formed by the first drying hood 4 and the second drying hood 5. Before painting the door panel, hot air is introduced into the first diversion groove 8 and the second diversion groove 11 through the diversion pipe 9 by the hot air mechanism and discharged through the air guide frame 12, so that when the hot air enters the inside of the cylinder formed by the first drying hood 4 and the second drying hood 5, it is dispersed by a plurality of air guide frames 12, reducing the thrust of the hot air and making the hot air evenly fill the inside of the cylinder composed of the first drying hood 4 and the second drying hood 5 to achieve the purpose of heating the door panel. Then, the door panel is painted by the door panel painting device 6. Since the door panel is heated by the hot air, the surface of the door panel has a relatively high temperature at this time. After the paint contacts the door panel, it will absorb the heat of the door panel and quickly dry the paint. At the same time, the hot air mechanism is always in a working state and dries the outer surface of the paint (i.e., the side not in contact with the door panel). At this time, since the position where the paint contacts the door panel absorbs the heat of the door panel and dries, the paint is not easily affected by the wind and flows. And the hot air entering the inside of the cylinder is dispersed by the air guide frame 12, and the thrust of the hot air is reduced, which can effectively prevent the wind from pushing the paint to move, and thus can effectively achieve the effect of protecting the paint surface and avoid the problem of uneven paint caused by the flow of the paint.

[0035] In a further preferred embodiment of the present invention, as Figures 1 - 5 shown, the door panel painting device 6 includes two groups of door panel clamps 61 and a painting mechanism 62. The two groups of door panel clamps 61 are respectively connected to the upper end of the base 1 and the bottom end of the extension plate 7.

[0037] In a further preferred embodiment of the present invention, as Figures 1 - 5 shown, the door panel clamp 61 includes a fixed rod 611. The fixed rod 611 is fixedly connected to the base 1. Positioning rods 612 are slidably arranged on both sides of the top end of the fixed rod 611. An adjusting screw 613 is threadedly connected to the middle of the top end of the fixed rod 611. The top ends of the positioning rod 612 and the adjusting screw 613 are jointly connected to a door panel clip 614.

[0038] In this embodiment, the fixed rod 611 is provided to install the positioning rod 612 and the adjusting screw 613. When installing the wooden door panel, the two ends of the wooden door are respectively corresponding to the door panel clips 614 of the two groups of door panel clamps 61. By rotating the adjusting screw 613, the relative position of the door panel clip 614 and the fixed rod 611 is controlled to achieve the purpose of fixing the door panel.

[0039] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the paint spraying mechanism 62 includes two connecting plates 621, the two connecting plates 621 are respectively connected to the side walls of the two fixing rods 611, two guide rods 622 are commonly connected between the two connecting plates 621, a support plate 623 is commonly connected to the outer walls of the two guide rods 622, a spray head 624 is arranged on the support plate 623 towards the direction of the fixing rod 611, and a paint spraying pipe 625 is arranged on the side wall of the support plate 623.

[0040] In this embodiment, through the arrangement of the two connecting plates 621, the guide rods 622 are installed, and the support plate 623 is installed through the guide rods 622, so that the support plate 623 can only move along the direction of the guide rods 622. Since when installing the wooden door panel, the two ends of the wooden door are respectively corresponding to the door panel clamping pieces 614 of the two groups of door panel clamps 61, at this time, the linear direction of the wooden door is the same as that of the guide rods 622. When the support plate 623 moves along the guide rods 622, the paint can be sprayed on the surface of the door panel through the paint spraying pipe 625 and the spray head 624.

[0041] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, two groups of the paint spraying mechanisms 62 are provided and are respectively installed on both sides of the two fixing rods 611.

[0042] In this embodiment, through the arrangement of the two groups of paint spraying mechanisms 62, the two sides of the door panel can be sprayed simultaneously, and thus the paint spraying efficiency can be effectively improved.

[0043] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, a positioning pipe 13 is arranged at the top end of the first housing 2, the diversion pipe 9 passes through the positioning pipe 13, and a rotating groove 14 is opened at a position of the second housing 3 corresponding to the positioning pipe 13.

[0044] In this embodiment, through the arrangement of the positioning pipe 13 and the rotating groove 14, the rotation stability between the second housing 3 and the first housing 2 is improved.

[0045] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the air guide frame 12 is conical, and its conical end penetrates through the inner wall of the first housing 2 and is communicated with the first diversion groove 8.

[0046] In this embodiment, since the air guide frame 12 is conical and the conical end is communicated with the first diversion groove 8, when hot air enters the first diversion groove 8 and is then discharged through the air guide frame 12, the conical air guide frame 12 will further expand the area affected during air discharge, thereby achieving the purpose of further reducing the thrust of the hot air during discharge.

[0047] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
