Description

Technical Field

[0001] The invention relates to the technical field of wood floor processing, and in particular to a wood floor processing spray paint device and a use method thereof. Background Art

[0002] The painting process in the production of wooden flooring includes pretreatment to sand, remove dust and apply primer, followed by uniform painting using an automatic painting line. After painting, the paint surface is cured by a hot air, infrared or ultraviolet drying system, followed by light sanding and finishing to ensure that the paint surface is smooth and flawless. Finally, strict quality inspection is carried out to confirm that the paint surface is uniform, glossy, adherent and hardness meet the standards. Painting not only protects wood from wear and moisture and extends its service life, but also improves its aesthetics by changing its color and gloss. It also provides anti-slip and wear-resistant functions and is easy to clean and maintain. Therefore, the entire painting process is a key link in ensuring quality and functionality in wooden flooring production.

[0003] In the wood floor spray painting process, it is crucial to ensure the flatness and beauty of the paint surface. Existing spray painting devices are mainly divided into two categories: single-sided spray painting and double-sided simultaneous spray painting. When the single-sided spray painting method is adopted, the wooden board needs to be turned over to spray the other side after one side is sprayed. However, the gravity and centrifugal force during the turning process will cause the incompletely cured paint surface to deform, and even paint liquid will drip, which will seriously affect the quality of the paint surface and cause the surface to be uneven or have traces of paint dripping. Although the double-sided simultaneous spray painting technology is intended to improve the spray painting efficiency, during the implementation process, the downward wooden board surface is also difficult to avoid the problem of paint liquid flow under the influence of gravity. This not only affects the original intention of improving the spray painting efficiency, but more importantly, it is impossible to guarantee the perfection of the paint surface. Based on this, the present invention purposely provides a wooden floor processing spray painting device and a method of using the same, which can improve the spray painting efficiency while avoiding the reduction of the flatness of the paint surface under the action of gravity. Summary of the invention

[0008] As a further solution of the present invention: the unloading assembly includes a conveying rod, and the number of the conveying rods is multiple, and the multiple conveying rods are rotatably installed on the machine body, and the multiple conveying rods are horizontally arranged at equal intervals, and two adjacent conveying rods are connected by a synchronous belt drive, and one of the conveying rods is driven to rotate by an output source.

[0009] As a further solution of the present invention: the unloading assembly also includes a second electric cylinder, a support plate and a spacer, a spacer is arranged in the middle of the conveying rod, the second electric cylinder is fixedly installed at the bottom of the machine body, and a support plate is fixedly installed at its movable end. When the second electric cylinder contracts, the support plate is located under the conveying rod; when the second electric cylinder extends, the support plate passes through the spacer and abuts against the bottom of the wooden floor, and the projection of the spacer on the wooden floor is much smaller than the wooden floor.

[0010] As a further solution of the present invention: the paint spraying assembly includes a paint spraying rod, a lifting platform and a first electric cylinder, the first electric cylinder is fixedly installed on the top of the machine body, the lifting platform is fixedly connected to the movable end of the first electric cylinder, and the paint spraying rod is slidably installed on the lifting platform.

[0012] A method for using a wood floor processing and painting device, the method is applied to the wood floor processing and painting device as described above, the method comprising the following steps: Step S1: clamp and fix the two wooden floors respectively through the clamping components of the support frames at both ends of the rotating bracket, and then drive the rotating bracket to rotate to a vertical state by a driving source; Step S2: spray paint on one side of the wooden floor in the spray paint area by using the spray paint assembly, then unlock the upper locking assembly and lock the lower locking assembly; Step S3: The driving source drives the rotating bracket to rotate 180 degrees, and the wooden floor with wet paint surface rotates from the spray painting area to the drying area and is dried by the infrared irradiation lamp. At the same time, another wooden floor rotates from the drying area to the spray painting area. During the rotation process, the paint surface of the wooden floor with paint surface always faces upward, and the side of the wooden floor in the drying area facing away from the infrared irradiation lamp will rotate to below the spray painting assembly; Step S4: repeat step S2, and then drive the rotating bracket to rotate 180 degrees, the wooden floor after the paint surface is dried rotates from the drying area to the painting area, and turns over on one side during the rotation process, and the wooden floor just painted rotates from the painting area to the drying area, and the wooden floor whose paint surface is not dry is always in a horizontal state during the rotation process; Step S5: Repeat steps S2-S4 until both sides of a wooden floor are painted and dried, then the material can be cut at the cutting assembly, and then the new wooden floor can be reinstalled on the vacant support frame.

[0013] Beneficial effects of the present invention: 1. In the present invention, the two wooden floors are alternately passed through the painting area and the drying area by rotating the bracket, so that the upper wooden floor is painted by the painting assembly while the lower wooden floor is being dried by the infrared irradiation lamp. The key is to ensure that the undried paint surface on the upper wooden floor is always facing upward during the process of switching the position of the wooden floor up and down through the cooperation of the hollow disc and the locking assembly. At the same time, the lower wooden floor after drying can accurately turn the unpainted side toward the painting assembly to prepare for the next round of painting operation. This not only improves the production efficiency, but also avoids the problem that the undried paint surface of the wooden floor faces downward, causing the paint liquid to drip due to gravity, thereby ensuring the flatness of the paint surface; 2. In the present invention, when the support frame is in a vertical state, it means that the locking assembly is in a locked state. At this time, the hollow disc cannot rotate on the rotating bracket, and the support frame in a vertical state uses the natural structure of its bottom frame to form a stable bearing platform, which can directly support the wooden floor. Then, the wooden floor can be easily clamped and fixed by the clamping assembly, which cleverly solves the problem that the support frame has no support in the middle when in a horizontal state, and requires the wooden floor to be suspended between the clamping assemblies to wait for clamping, which is not only cumbersome to operate, but also increases the difficulty and safety hazards of installation, causing inconvenience in installation; 3. In the present invention, the second electric cylinder is extended to push the support plate through the gap to abut against the bottom of the wooden floor. At this time, the clamping assembly releases the wooden floor, and then the second electric cylinder is retracted. The support plate will move downward with the wooden floor until the wooden floor is lowered to the conveying rod and conveyed. This ensures that the wooden floor is gently placed on the conveying rod, thereby avoiding the impact caused by direct falling, which may damage the paint surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 7 As shown, the present invention is a wood floor processing and painting device, comprising: A machine body 1 is provided with a paint spraying assembly 2 on the top and a material discharge assembly 9 on the bottom. A fixing frame 3 is fixedly installed on the machine body 1, and the fixing frame 3 is located between the paint spraying assembly 2 and the material discharge assembly 9. An infrared irradiation lamp 4 is fixedly installed on the bottom. A paint spraying area is between the fixing frame 3 and the paint spraying assembly 2, and a drying area is between the infrared irradiation lamp 4 and the material discharge assembly 9. There are two rotating brackets 5, and the two rotating brackets 5 are symmetrically arranged about the fixed frame 3. The infrared irradiation lamp 4 is located between the two rotating brackets 5. The rotating bracket 5 is rotatably installed on the fixed frame 3, and is driven to rotate by a driving source. A hollow disc 6 is rotatably installed at both ends of each rotating bracket 5. Two hollow discs 6 located at the same horizontal height are fixedly connected by a support frame 7. The support frame 7 is arranged horizontally and is clamped and fixed with a wooden floor 8 by a clamping assembly. Each hollow disc 6 is filled with iron sand 601, and each hollow disc 6 is connected to the rotating bracket 5 by a corresponding locking assembly 10. When the locking assembly 10 is locked, the hollow disc 6 is clamped and fixed to the rotating bracket 5; when the locking assembly 10 is unlocked, the hollow disc 6 is rotatably connected to the rotating bracket 5; and When the rotating bracket 5 is in a vertical state, one end of it is located in the paint spraying area and the other end of it is located in the drying area. When the rotating bracket 5 rotates, the hollow disc 6 at one end thereof rotates from the paint spraying area to the drying area, and the locking assembly 10 corresponding to the hollow disc 6 is unlocked; the hollow disc 6 at the other end thereof rotates from the drying area to the paint spraying area, and the locking assembly 10 corresponding to the hollow disc 6 is locked.

[0019] In one case of this embodiment, the driving source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0020] In actual application of this embodiment, when the locking assembly 10 is unlocked, the rotating bracket 5 is rotatably connected to the hollow disc 6. At this time, when the driving source drives the rotating bracket 5 to rotate, the rotating bracket 5 will drive the hollow disc 6 to revolve around the axis of the rotating bracket 5. When the hollow disc 6 revolves, Figure 5 As shown, the iron sand 601 therein is continuously filled into the lower half of the hollow disc 6 under the action of gravity, and the hollow disc 6 is continuously rotated in the rotating bracket 5 under the action of gravity, so that the hollow disc 6 and the support frame 7 connecting the two hollow discs 6 always revolve around the axis of the rotating bracket 5 in a horizontal posture, that is, the top surface of the wooden floor 8 on the support frame 7 is always facing upward; and when the locking assembly 10 is locked, the rotating bracket 5 is clamped and fixed with the hollow disc 6, and the hollow disc 6 cannot rotate in the rotating bracket 5. At this time, when the rotating bracket 5 drives the hollow disc 6 to revolve, the top surface of the wooden floor 8 on the support frame 7 is always away from the fixed frame 3; by Figure 1 Taking the example shown in the figure, assuming that the top surface of the wooden floor 8 below has been painted, a synchronous drying and painting operation can be performed at this time, that is, the wooden floor 8 below is dried by the infrared irradiation lamp 4 and the wooden floor 8 above is painted by the paint spraying assembly 2 simultaneously. After completion, a locking assembly 10 switching operation is performed, that is, the upper locking assembly 10 is unlocked, and the lower locking assembly 10 is locked, and then the driving source drives the rotating bracket 5 to flip 180 degrees. At this time, the wooden floor 8 above, whose paint surface is not dry, always rotates to the bottom of the infrared irradiation lamp 4 with the paint surface facing up, and the wooden floor 8 below will flip to the painting area, and the side that has not been painted faces the paint spraying assembly 2, and the side whose paint surface is dried faces away from the paint spraying assembly 2. At this time, the synchronous drying and painting operation-locking assembly 10 switching operation-rotating bracket 5 flipping 180 degrees can be cycled until both sides of a wooden floor 8 are painted and dried, and then unloading can be performed at the unloading assembly 9, and then the new wooden floor 8 can be reinstalled on the vacant support frame 7; Furthermore, since the iron sand 601 is always filled in the lower half of the hollow disc 6, its center of gravity is stable, and when the locking assembly 10 above is unlocked, the hollow disc 6 will not turn over; By rotating the bracket 5, the two wooden floors 8 are allowed to alternately pass through the painting area and the drying area, so that the upper wooden floor 8 is being painted by the painting assembly 2 while the lower wooden floor 8 is being dried by the infrared lamp 4. The key lies in the cooperation of the hollow disc 6 and the locking assembly 10 to ensure that the undried paint surface on the upper wooden floor 8 always remains facing upward during the process of switching the wooden floor 8 up and down. At the same time, the dried wooden floor 8 at the lower side can accurately turn the unpainted side over to face the painting assembly 2 to prepare for the next round of painting operations. This not only improves the production efficiency, but also avoids the problem of the undried paint surface of the wooden floor 8 facing downward, causing the paint liquid to drip due to gravity, thereby ensuring the flatness of the paint surface.

[0021] like Figure 1-Figure 2 As shown, as a preferred embodiment of the present invention, when the rotating bracket 5 rotates to a horizontal state, the support frame 7 at one end thereof is in a horizontal state, and the support frame 7 at the other end thereof is in a vertical state, and the support frame 7 in the vertical state is used to install the wooden floor 8.

[0022] In practical application, if Figure 2 As shown in the example, when the support frame 7 is in a vertical state, it means that the locking assembly 10 is in a locked state. At this time, the hollow disc 6 is partially restricted on the rotating bracket 5 and cannot rotate freely, thereby ensuring the stability and safety of the hollow disc 6 and the support frame 7. More importantly, the vertically placed support frame 7 utilizes the natural structure of its bottom frame to form a stable bearing platform that can directly support the wooden floor 8 without the need for an additional supporting structure. At this time, through the clamping assembly, the operator can easily and accurately clamp and fix the wooden floor 8 on the support frame 7, thus avoiding the situation where the support frame 7 is unsupported in the middle in a horizontal state, requiring the wooden floor 8 to be suspended between the clamping assemblies waiting for clamping, which is not only cumbersome to operate, but also increases the difficulty of installation and safety hazards. The support frame 7 in a vertical state not only provides stable support, but also simplifies the clamping process, making the entire installation process smoother and more efficient, greatly improving user experience and work efficiency.

[0023] like Figure 3-Figure 5 As shown, as a preferred embodiment of the present invention, the locking assembly 10 includes a U-shaped frame 501, a locking block 502, a first telescopic member 503 and a locking groove 602, the locking groove 602 is opened on the hollow disk 6, and is horizontally arranged, the U-shaped frame 501 is fixedly installed on the rotating bracket 5, which is horizontally arranged, and it is located on the same horizontal plane as the locking groove 602, the locking block 502 is slidably installed in the U-shaped groove of the U-shaped frame 501, and is fixedly connected to the movable end of the first telescopic member 503 fixedly installed on the rotating bracket 5, when the first telescopic member 503 is fully extended, the locking block 502 is misaligned with the locking groove 602; when the first telescopic member 503 is fully retracted, the locking block 502 is stuck in the locking groove 602.

[0024] In one case of this embodiment, the first telescopic member 503 may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving linear reciprocating motion, which is not specifically limited in this embodiment.

[0025] In actual application of this embodiment, when the hollow disc 6 rotates from the painting area to the drying area, the first telescopic member 503 is fully extended, and the locking block 502 is misaligned with the locking groove 602. At this time, the hollow disc 6 can rotate in the rotating bracket 5; and when the hollow disc 6 rotates from the drying area to the painting area, the first telescopic member 503 is fully retracted, and the locking block 502 is snapped into the locking groove 602. At this time, the hollow disc 6 and the rotating bracket 5 are snapped into a whole. Due to the obstruction of the locking block 502, the rotation of the hollow disc 6 is restricted, so that the hollow disc 6 is turned over with the rotation of the rotating bracket 5. Such a design can quickly switch the relationship between the rotating bracket 5 and the hollow disc 6, so as to adapt to different production rhythms and ensure the stability of the wooden floor 8 and the integrity of the paint surface during the painting and drying process; The U-shaped frame 501 and the locking groove 602 are both arranged horizontally and are located on the same horizontal plane, which means that no matter how many degrees the rotating bracket 5 is flipped, as long as the rotating bracket 5 is in a vertical state, the locking block 502 in the U-shaped frame 501 can be inserted into the locking groove 602.

[0026] like Figure 6-Figure 7 As shown, as a preferred embodiment of the present invention, the unloading component 9 includes a conveying rod 901, and the number of the conveying rods 901 is multiple, and the multiple conveying rods 901 are rotatably installed on the machine body 1, and the multiple conveying rods 901 are horizontally arranged at equal intervals, and two adjacent conveying rods 901 are connected by a synchronous belt drive, and one of the conveying rods 901 is driven to rotate by an output source.

[0027] In one case of this embodiment, the output source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0028] In actual application of this embodiment, two adjacent conveying rods 901 are connected by a synchronous belt drive, which means that all conveying rods 901 have the same direction. In this way, when the wooden floor 8 falls onto the conveying rods 901, it can be conveyed in one direction by the conveying rods 901, thereby facilitating collection.

[0029] like Figure 6-Figure 7As shown, as a preferred embodiment of the present invention, the unloading assembly 9 also includes a second electric cylinder 902, a support plate 903 and a spacer 904. The spacer 904 is arranged in the middle of the conveying rod 901. The second electric cylinder 902 is fixedly installed at the bottom of the machine body 1, and the support plate 903 is fixedly installed at the movable end thereof. When the second electric cylinder 902 contracts, the support plate 903 is located below the conveying rod 901. When the second electric cylinder 902 extends, the support plate 903 passes through the spacer 904 and abuts against the bottom of the wooden floor 8. The projection of the spacer 904 on the wooden floor 8 is much smaller than the wooden floor 8.

[0030] In one case of this embodiment, it should be noted that the second electric cylinder 902 described in the present invention is the prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0031] In practical application, if Figure 6 As shown, the second electric cylinder 902 is extended to push the support plate 903 through the gap 904 to abut against the bottom of the wooden floor 8. At this time, the clamping assembly releases the wooden floor 8, and then the second electric cylinder 902 is retracted, and the support plate 903 will support the wooden floor 8 and move downward, as shown in FIG. Figure 7 As shown, until the wooden floor 8 drops to the conveying rod 901, the conveying rod 901 will convey the wooden floor 8. Placing the wooden floor 8 slowly on the conveying rod 901 can avoid the situation where the wooden floor 8 falls directly and causes damage to the paint surface.

[0032] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the paint spraying assembly 2 includes a paint spraying rod 201, a lifting platform 202 and a first electric cylinder 203, the first electric cylinder 203 is fixedly installed on the top of the body 1, the lifting platform 202 is fixedly connected to the movable end of the first electric cylinder 203, and the paint spraying rod 201 is slidably installed on the lifting platform 202.

[0033] In one case of this embodiment, it should be noted that the first electric cylinder 203 described in the present invention is the prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0034] In actual application of this embodiment, the lifting platform 202 can be controlled to rise and fall through the first electric cylinder 203. When painting is needed, the lifting platform 202 is controlled to descend so that the paint spraying rod 201 is close to the surface of the wooden floor 8, thereby reducing the diffusion range of the paint sprayed by the paint spraying rod 201. After the painting is completed, the first electric cylinder 203 is immediately controlled to rise to avoid blocking the path of the wooden floor 8 revolving around the rotating bracket 5. This can improve the effect of painting and make the paint spraying more uniform.

[0035] like Figure 4-Figure 5 As shown, as a preferred embodiment of the present invention, the clamping assembly includes a second telescopic member 701 and a splint 702, and the four second telescopic members 701 are respectively fixedly installed on the four sides of the support frame 7, and a splint 702 is fixedly installed at the movable end of each second telescopic member 701, and the splint 702 is abutted against the frame of the wooden floor 8.

[0036] In one case of this embodiment, the second telescopic member 701 may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving linear reciprocating motion, which is not specifically limited in this embodiment.

[0037] In actual application of this embodiment, the wooden floor 8 is placed between the four plywoods 702, and then the second telescopic member 701 is simultaneously activated to quickly clamp and fix the wooden floor 8 between the support frames 7. This allows for convenient and quick installation of the wooden floor 8, and also allows for quick unloading of the wooden floor 8 that has been painted on both sides.

[0038] See also Figure 1-Figure 7 As shown, the present invention is a method for using a wood floor processing and painting device, and the method is applied to a wood floor processing and painting device as described in the above embodiment, and the method includes the following steps: Step S1: The two wooden floors 8 are clamped and fixed by the clamping components of the support frames 7 at both ends of the rotating bracket 5, and then the driving source drives the rotating bracket 5 to rotate to a vertical state; Step S2: spray paint on one side of the wooden floor 8 located in the spray paint area by using the spray paint assembly 2, then unlock the upper locking assembly 10 and lock the lower locking assembly 10; Step S3: The driving source drives the rotating bracket 5 to rotate 180 degrees, and the wooden floor 8 with wet paint surface rotates from the painting area to the drying area and is dried by the infrared irradiation lamp 4. At the same time, another wooden floor 8 rotates from the drying area to the painting area. During the rotation process, the paint surface of the wooden floor 8 with paint surface is always facing upward, and the side of the wooden floor 8 in the drying area away from the infrared irradiation lamp 4 will rotate to the bottom of the painting assembly 2; Step S4: repeat step S2, and then drive the rotating bracket 5 to rotate 180 degrees, the wooden floor 8 after the paint surface is dried rotates from the drying area to the painting area, and turns over on one side during the rotation process, while the wooden floor 8 just after the paint is sprayed rotates from the painting area to the drying area, and the wooden floor 8 whose paint surface is not dry is always in a horizontal state during the rotation process; Step S5: Repeat steps S2-S4 until both sides of a wooden floor 8 are painted and dried, then unloading can be carried out at the unloading assembly 9, and then the new wooden floor 8 can be reinstalled on the vacant support frame 7.

[0039] Working principle of the present invention: The above embodiment of the present invention provides a wood floor processing and painting device and its use method, which ensures that the top surface of the wooden floor 8 below has been painted. At this time, a synchronous drying and painting operation can be performed, that is, the wooden floor 8 below is dried by the infrared irradiation lamp 4 and the wooden floor 8 above is painted by the painting assembly 2 simultaneously. After completion, a locking assembly 10 switching operation is performed, that is, the upper locking assembly 10 is unlocked, and the lower locking assembly 10 is locked, and then the driving source drives the rotating bracket 5 to flip 180 degrees. At this time, the wooden floor 8 with undried paint on the upper surface is always rotated to the bottom of the infrared irradiation lamp 4 with the paint surface facing up, and the wooden floor 8 below will flip to the painting area, and the side that has not been painted faces the painting assembly 2, and the side where the paint surface is dried is away from the painting assembly 2. At this time, the synchronous drying and painting operation-locking assembly 10 switching operation-rotating bracket 5 flipping 180 degrees can be cyclically operated until both sides of a wooden floor 8 are painted and dried, and then unloading can be performed at the unloading assembly 9, and then the new wooden floor 8 can be reinstalled on the vacant support frame 7.

[0040] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
