Description

Technical Field

[0001] The present invention relates to the technical field of wood-based panel processing, and particularly to a drying device for spray painting of wood-based panels. Background Art

[0002] Wood-based panels are panels processed mainly from wood and are widely used in fields such as construction, furniture, and decoration. According to different processing methods and uses, wood-based panels can be divided into various types: solid wood panels, wood-based artificial boards, blockboards (fine woodworking boards), wood particle boards, multi-layer boards (plywood), density boards, etc.

[0003] Spray painting and drying of wood-based panels is an important process to ensure a uniform, durable, and beautiful paint film on the surface of the panels, mainly including pre-treatment before spray painting, spray painting process, drying technology, and quality control, etc.

[0004] When the existing wood-based panels are spray painted and subsequently dried, they need to be fixedly arranged. During the fixed arrangement, the fixing components will block some areas of the panel, hindering the spray painting process in these areas. And during drying, due to the obstruction, it is difficult for the paint film to cover these parts of the panel, resulting in these parts of the panel being directly in a long-term drying state, and it is difficult to effectively solve this problem during drying. As a result, it is easy for these parts of the wood-based panel to be over-dried and develop cracks and other adverse conditions, affecting the quality of spray painting and drying of the wood-based panel.

[0033] Specifically, during drying, the wooden board enters the drying chamber 2 for drying. After the paint film on its surface is initially cured, the air pump body 729 is started. The air pump body 729 conveys gas through the connecting pipe 730 into the fixed airbag 727, causing the fixed airbag 727 to drive the anti-slip cushion 713 to expand, so that the anti-slip cushion 713 contacts the wooden board and continuously applies pressure until the fixed airbag 727 cooperates with the anti-slip cushion 713 to fix the wooden board. At this time, the servo motor 704 is started, and the servo motor 704 drives the installation shaft rod 726 to rotate, thereby causing the installation shaft rod 726 to drive the rotating disk frame 722, the fixed rotating rod 712, and the adjusting reel 721 to rotate. At this time, the fixed rotating rod 712 can drive the board fixing member 711 to separate from the wooden board. At the same time, when the rotating disk frame 722 rotates, it can drive the fixed airbag 727 and the anti-slip cushion 713 to rotate, causing the wooden board to drop a certain distance. At the same moment, the adjusting reel 721 rotates to tighten the connecting cable 710, and the connecting cable 710 can pull the connecting bracket 709, thereby causing the connecting bracket 709 to drive the paint tank 706, the paint replenishing pump 707, and the spraying member 724 to rise, so that the position of the spraying member 724 corresponds to the position where the original board fixing member 711 was located on the wooden board. At this time, the paint replenishing pump 707 operates, and the paint replenishing pump 707 conveys the paint in the paint tank 706 through the conveying pipe 708 and the connecting pipe 725 into the spraying member 724 and sprays the paint through the spraying member 724 to protect the areas of the wooden board lacking the paint film. After drying, the driving motor 716 operates and drives the driving wheel 715 to operate, so that the driving wheel 715 cooperates with the auxiliary wheel 714 to drive the guide rail seat 701 to move on the guide rail body 4 and move out of the drying chamber 2;

[0034] In a specific application scenario, the drying and paint replenishing module 7 is applicable to the drying link after the spraying process of wooden boards, that is, the drying and paint replenishing module 7 can spray paint on the areas of the wooden board lacking the paint film during the drying process of the wooden board, so as to spray and cover the exposed areas during spraying, so as to avoid adverse situations such as cracking due to excessive drying of the wooden board lacking the protection of the paint film in this part during drying, thereby increasing the drying quality of the wooden board during drying and improving the use effect of the device. Moreover, during drying and paint replenishing, the device will perform the paint replenishing operation after the paint film on the wooden board is initially cured to avoid damage to the paint film on the surface of the wooden board during the paint replenishing process, so as to further improve the use effect of the device and the quality of the dried wooden board products.

[0035] Refer to Figure 2 、 Figure 8 、 Figure 9 and Figure 10, in a preferred embodiment, the odor treatment module 5 further includes a plurality of connecting square pipes 506, and the plurality of connecting square pipes 506 are all arranged on the deodorization bin 3. One end of each of the plurality of connecting square pipes 506 is fixedly connected to the same spray bin 509. The spray disc 510 is located inside the spray bin 509, and a spray pump 505 is fixedly connected to the top of the spray bin 509. The output end of the spray pump 505 is fixedly connected to a liquid inlet pipe 504, and the output end of the spray pump 505 is fixedly connected to the input end of the spray disc 510 through a pipeline; a plurality of through pipe fittings 519 are fixedly connected to the bottom of the spray bin 509, and the output ends of the plurality of through pipe fittings 519 are fixedly connected to the same annular pipe 518. A drain pipe 516 is fixedly connected to the outer wall of the annular pipe 518, and an installation hole is opened at the bottom of the spray bin 509. A gas bin member 514 is fixedly connected inside the installation hole. The bottom of the gas bin member 514 is connected to an input end of a treatment bin 501 through a pipeline by a transfer pump 515; the gas bin member 514 is located inside the spray bin 509, a water guide cover 512 is fixedly connected to the top of the gas bin member 514, a plurality of air inlets 513 are equidistantly opened on the outer wall of the gas bin member 514, and a return pipe 507 is fixedly connected to the bottom of the treatment bin 501; two installation openings are opened on the outer wall of the deodorization bin 3, and a flow-through gas bin 503 is fixedly connected to the inner wall of each of the two installation openings. A plurality of air flow holes 508 are opened on the two flow-through gas bins 503, and two connecting through pipes 502 are fixedly connected to the outer walls of the two flow-through gas bins 503. The output end of the return pipe 507 is communicated with the inside of one of the flow-through gas bins 503.

[0036] Specifically, before drying and discharging, the paint film on the wood board emits odor when heated. At this time, the transfer pump 515 operates and transports the gas inside the gas bin member 514 to the inside of the treatment bin 501 through a pipeline, so that the inside of the gas bin member 514 is in a negative pressure state. Furthermore, the gas bin member 514 inhales the odor inside the deodorization bin 3 into the spray bin 509 through the air inlets 513 and the connecting square pipes 506. When the odor gas enters the spray bin 509, the spray pump 505 operates. The spray pump 505 transports the wood paint deodorant to the inside of the spray disc 510 through the liquid inlet pipe 504 and sprays it. The sprayed gas is transported to the inside of the treatment bin 501 and is secondarily treated by the activated carbon 517 inside it. The treated gas is transported to the flow-through gas bin 503 through the return pipe 507 and is ejected through the air flow holes 508 to increase the gas fluidity inside the deodorization bin 3 (increase the odor treatment efficiency) until the drying operation is completed;

[0037] In a specific application scenario, the odor treatment module 5 is applicable to the drying and discharging process of wood-based panels. That is, the odor treatment module 5 can purify the odor generated by the heat of the paint on the wood-based panels after painting and drying, so as to reduce the adverse effects of the odor on the health of the staff when the gas escapes, thereby improving the safety effect of the device during use. And when treating the odor, the device adopts a combination of spraying a wood paint deodorant and adsorbing with activated carbon 517 to improve the purification effect of the odor during treatment, further increasing the safety during the operation and use of the device. At the same time, during the treatment, the device can increase the air flow inside the deodorization chamber 3 to improve the odor treatment efficiency.

[0038] Working principle: During drying, the wood-based panel enters the drying chamber 2 for drying. When the paint film on its surface is initially cured, the air pump body 729 is started. The air pump body 729 transports the gas through the connecting pipe 730 into the fixed airbag 727, and makes the fixed airbag 727 drive the anti-slip cushion 713 to expand, so that the anti-slip cushion 713 contacts the wood-based panel, and continuously applies pressure until the fixed airbag 727 cooperates with the anti-slip cushion 713 to fix the wood-based panel. At this time, the servo motor 704 is started, and the servo motor 704 drives the mounting shaft 726 to rotate, and then the mounting shaft 726 drives the rotating disk frame 722, the fixed rotating rod 712 and the adjusting reel 721 to rotate. At this time, the fixed rotating rod 712 can drive the plate fixing member 711 to separate from the wood-based panel. At the same time, when the rotating disk frame 722 rotates, it can drive the fixed airbag 727 and the anti-slip cushion 713 to rotate, so that the wood-based panel descends a certain distance. At the same moment, the adjusting reel 721 rotates to tighten the connecting cable 710, and the connecting cable 710 can pull the connecting bracket 709, and then the connecting bracket 709 drives the paint tank 706, the paint replenishing pump 707 and the spraying member 724 to rise, so that the position of the spraying member 724 corresponds to the position of the original plate fixing member 711 on the wood-based panel. At this time, the paint replenishing pump 707 operates, and the paint replenishing pump 707 transports the paint in the paint tank 706 through the delivery pipe 708 and the communicating pipe 725 into the spraying member 724, and sprays the paint through the spraying member 724 to protect the parts of the wood-based panel lacking the paint film.

[0039] Before drying and discharging, the paint film on the wood board emits an odor when heated. At this time, the conveying pump 515 operates and conveys the gas inside the air storage part 514 to the inside of the treatment bin 501 through a pipeline, so that the inside of the air storage part 514 is in a negative pressure state. Furthermore, the air storage part 514 sucks the odor inside the deodorization bin 3 into the spray bin 509 through the air inlet 513 and the connecting square pipe 506. When the odor gas enters the inside of the spray bin 509, the spray pump 505 operates. The spray pump 505 conveys the wood paint deodorant to the inside of the spray disc 510 through the liquid inlet pipe 504 and sprays it. The gas after spraying is conveyed to the inside of the treatment bin 501 and undergoes secondary treatment through the activated carbon 517 inside it. The treated gas is conveyed to the circulation air storage 503 through the return pipe 507 and ejected through the air flow holes 508 to increase the gas fluidity inside the deodorization bin 3 until the drying operation is completed;

[0040] After drying, the drive motor 716 operates and drives the drive wheel 715 to operate, so that the drive wheel 715 cooperates with the auxiliary wheel 714 to drive the guide rail seat 701 to move on the guide rail body 4 and move out of the drying bin 2.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
