Description

Technical Field

[0001] This invention relates to the field of decorative wood panel production and processing technology, and in particular to an auxiliary device for applying putty in decorative wood panel processing. Background Technology

[0002] As people's living standards improve, their demands for the aesthetics and durability of interior decoration are increasing. Decorative wood panels, as a common material in interior decoration, directly affect the overall decorative effect due to their surface quality. Puttying, as a surface treatment process, can fill tiny holes, gaps, and uneven areas on the surface of decorative wood panels, providing a smooth and flat base for subsequent decorative processes such as painting and wallpapering.

[0003] Currently, in the application of decorative wood panels, the putty on these panels is prone to peeling off, mainly due to the following two reasons: First, decorative wood panels themselves are easily bent and deformed. In daily environments, changes in temperature and humidity cause decorative wood panels to expand, contract, and bend to a certain extent. When the putty adheres to the surface of the decorative wood panel and dries and hardens, its limited flexibility makes it difficult to deform synchronously with the wood panel. Under continuous stress, the bonding force between the putty and the decorative wood panel gradually weakens, eventually leading to separation. Another reason is the poor adhesion of the putty due to ineffective surface treatment of the decorative wood panel. Because the surface of decorative wood panels often retains impurities such as sawdust, grease, and dust, the affinity between the wood panel and the putty is poor. Therefore, once subjected to external impacts or vibrations, the putty easily falls off the surface of the decorative wood panel. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this invention is to provide an auxiliary device for applying putty to decorative wood panels, which makes the putty adhere more tightly to the decorative wood panels and reduces the possibility of putty falling off later.

[0006] To achieve the above objectives, this invention proposes a putty-applying auxiliary device for decorative wood panel processing, comprising a surface roughening mechanism and a putty-applying mechanism. The surface roughening mechanism is used to roughen the surface of the decorative wood panel, and the putty-applying mechanism is used to apply putty to the roughened surface of the decorative wood panel. The surface roughening mechanism includes a grinding plate, a fixed plate, and a balancing pendulum. The grinding plate is disposed at the bottom of the fixed plate, and its bottom surface has a grinding surface for roughening the decorative wood panel. The balancing pendulum is disposed at the top of the fixed plate. An opposing swing assembly is disposed between the grinding plate and the balancing pendulum, and the opposing swing assembly is used to drive the grinding plate and the balancing pendulum to swing horizontally opposite each other relative to the fixed plate. The putty-applying mechanism includes a putty box and a putty outlet disposed at the rear of the grinding plate. The putty box is used to transfer the putty stored inside to the putty outlet, and the putty outlet is used to apply the putty to the surface of the decorative wood panel.

[0007] Furthermore, the grinding surface is provided with grinding teeth, the grinding teeth are strip-shaped, the bottom of the grinding teeth is provided with a cutting edge, and the traveling head of the grinding plate is provided with a rocker.

[0008] Furthermore, the opposing oscillating assembly includes an oscillating drive motor, a reduction gear, and an oscillating crank. The fixed plate has an oscillating groove inside, and the oscillating drive motor, reduction gear, and oscillating crank are all located inside the oscillating groove. The power shaft of the oscillating drive motor is provided with a gear head. There are two reduction gears, which mesh with the gear head respectively. Each reduction gear has an oscillating crank pivotally connected to its edge. One end of the oscillating crank opposite to the reduction gear is pivotally connected to the balance plate, and the other end of the oscillating crank opposite to the reduction gear is pivotally connected to the grinding plate. The two oscillating cranks are centrally symmetrical with respect to the gear head.

[0009] Furthermore, guide sliders are provided on both sides of the fixed plate, and guide grooves are provided inside the balance pendulum and the grinding plate, and the guide grooves are adapted to the guide sliders; the balance pendulum and the grinding plate have the same mass.

[0010] Furthermore, the walking tail end of the grinding plate is provided with a brushing and combing mechanism, which includes a combing roller. The walking tail end of the grinding plate is provided with a combing guide shroud. The combing roller is rotatably disposed at the bottom of the combing guide shroud. The surface of the combing roller is provided with a comb. The two ends of the combing roller are provided with first shock-absorbing brackets. The combing guide shroud is provided with a combing roller drive motor for driving the combing roller to rotate.

[0011] Furthermore, the carding roller has a hollow mesh structure, a negative pressure fan is provided on the top of the carding guide hood, a filter element is provided at the air outlet of the negative pressure fan, and a waste plug is provided on the filter element.

[0012] Furthermore, both ends of the grinding plate are provided with a traveling mechanism. The traveling mechanism includes a drive roller and a drive roller housing.

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following description, in conjunction with the accompanying drawings, describes an auxiliary device for applying putty to decorative wood panels according to an embodiment of the present invention.

[0029] like Figures 2-5As shown in the embodiment of the present invention, the auxiliary device for applying putty for processing decorative wood panels includes a surface sanding mechanism 2 and a putty application mechanism 1. The surface sanding mechanism 2 is used to sand the surface of the decorative wood panel 5, and the putty application mechanism 1 is used to apply putty to the sanded surface of the decorative wood panel 5.

[0030] The surface sanding mechanism 2 includes a grinding plate 21, a fixed plate 23, and a balance swing plate 24. The grinding plate 21 is located at the bottom of the fixed plate 23, and the bottom of the grinding plate 21 is provided with a grinding surface 22 for sanding the surface of the decorative wood board 5. The balance swing plate 24 is located at the top of the fixed plate 23. An opposing swing assembly 28 is provided between the grinding plate 21 and the balance swing plate 24. The opposing swing assembly 28 is used to drive the grinding plate 21 and the balance swing plate 24 to swing horizontally opposite each other relative to the fixed plate 23.

[0031] The putty application mechanism 1 includes a putty box 11 and a putty outlet 15 located at the rear of the grinding plate 21. The putty box 11 is used to transfer the putty stored inside to the putty outlet 15, and the putty outlet 15 is used to apply the putty to the surface of the decorative wood board 5.

[0032] Specifically, when applying putty to the surface of the decorative wood panel 5, the decorative wood panel 5 is first fixed on a designated plane, then the putty box 11 of the device is filled with putty paste, the grinding plate 21 at the bottom of the device is attached to the decorative wood panel 5, and the grinding surface 22 is made to travel along the direction of the fiber texture 52 on the decorative wood panel 5.

[0033] As the device moves, the grinding plate 21 and the balance pendulum 24 are driven by the opposing pendulum assembly 28 to swing left and right (relative to the direction of device movement), such as... Figure 7 As shown, the grinding surface 22 loosens the fibers on the surface of the decorative wood board 5, forming a fluffy surface. Since the grinding surface 22 rubs the fiber texture 52 on the decorative wood board 5 from side to side, the fiber fluff 51 in the fluffy surface is raised in the middle and connected to the bottom of the decorative wood board 5 at both ends, making the fiber fluff 51 more firmly connected to the decorative wood board 5.

[0034] Subsequently, the decorative wood panel 5 is coated with putty by the putty scraping mechanism 1. The putty box 11 discharges the putty inside to the putty outlet 15. The putty outlet 15 applies the putty paste to the rough surface. The putty and the fibers 51 on the rough surface are fully integrated. Since the rough surface and the decorative wood panel 5 are connected, and the pitted structure of the rough surface increases the adhesion area of ​​the putty, the putty adheres more tightly to the decorative wood panel 5 after drying, thereby reducing the possibility of putty falling off later.

[0035] In one embodiment of the present invention, such as Figure 5 and Figure 6As shown, the grinding surface 22 is provided with grinding teeth 222, which are strip-shaped structures. The bottom of the grinding teeth 222 is provided with a cutting edge. The traveling head of the grinding plate 21 is provided with a rocker arm 221. The fixed plate 23 is provided with a pendulum drive motor and an eccentric pendulum 27. The power shaft of the pendulum drive motor is connected to the eccentric pendulum 27.

[0036] Specifically, strip-shaped grinding teeth 222 are provided on the grinding surface 22. As the cutting edges on the grinding teeth 222 travel along the decorative wood board 5, the cutting edges cut the wood fibers on both sides, and the grinding teeth 222 swing left and right to pull the cut fibers, making the fibers fluffy and forming a texture like... Figure 7 The fiber fluff 51 shown. During the left and right swinging of the cutting blade, in order to make full contact between the cutting blade and the decorative wood board 5, the pendulum drive motor inside the fixed plate 23 drives the eccentric pendulum 27 to rotate, so that the cutting blade swings left and right to grind the surface of the decorative wood board 5 and forms up and down squeezing and oscillating with the surface of the decorative wood board 5, so that the cutting blade and the decorative wood board 5 make full contact and increase the number of fiber fluff 51 generated.

[0037] The function of the rocker arm 221 is to prevent the front end of the grinding plate 21 from colliding with the protrusions on the surface of the decorative wood board 5 during the movement of the grinding plate 21, thus playing a role in obstacle avoidance and guidance.

[0038] In one embodiment of the present invention, such as Figures 2-4 As shown, the opposing swing assembly 28 includes a swing drive motor, a reduction gear 283 and a swing crank 284. The fixed plate 23 has a swing groove 281 inside, and the swing drive motor, reduction gear 283 and swing crank 284 are all located inside the swing groove 281.

[0039] A gear head 282 is provided on the power shaft of the oscillating drive motor. Two reduction gears 283 are provided, and the two reduction gears 283 mesh with the gear head 282 respectively. Each reduction gear 283 has an oscillating crank 284 pivotally connected to its edge. One end of the oscillating crank 284 opposite to the reduction gear 283 is pivotally connected to the balance plate 24, and the other end of the oscillating crank 284 opposite to the reduction gear 283 is pivotally connected to the grinding plate 21. The two oscillating cranks 284 are centrally symmetrical with respect to the gear head 282.

[0040] Specifically, during the left-right swinging process of the grinding plate 21, the swing drive motor drives the gear head 282 to rotate, the gear head 282 drives the two reduction gears 283 to rotate synchronously, and the two reduction gears 283 in turn drive the two swing cranks 284 to swing in opposite directions relative to the gear head 282, thereby driving the balance pendulum 24 and the grinding plate 21 to move synchronously in opposite directions. Since the balance pendulum 24 and the grinding plate 21 have the same mass, the vibrations that occur during the left-right movement of the grinding plate 21 are canceled out, thus improving the stability of the surface of the decorative wood board 5 during the sanding process.

[0041] In one embodiment of the present invention, such as Figure 4 As shown, guide sliders 25 are provided on both sides of the fixed plate 23, and guide grooves 26 are provided inside the balance plate 24 and the grinding plate 21. The guide grooves 26 are adapted to the guide sliders 25. This allows the balance plate 24 and the grinding plate 21 to move synchronously and in opposite directions along the fixed plate 23. The guide sliders 25 are connected to the fixed plate 23 by fixing screws 251, which facilitates the disassembly and maintenance of the guide sliders 25.

[0042] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, a brushing and combing mechanism 3 is provided at the walking tail of the grinding plate 21. The brushing and combing mechanism 3 includes a combing roller 34. A combing guide hood 35 is provided at the walking tail of the grinding plate 21. The combing roller 34 is rotatably mounted at the bottom of the combing guide hood 35. A comb 341 is provided on the surface of the combing roller 34. First shock-absorbing brackets 36 are provided at both ends of the combing roller 34 to make elastic contact with the surface of the decorative wood board 5, preventing hard contact with the surface of the decorative wood board 5 and squeezing damage to the decorative wood board 5. A combing roller drive motor 32 is provided on the combing guide hood 35 to drive the combing roller 34 to rotate.

[0043] Specifically, in order to make the fiber fluff 51 ground on the surface of the decorative wood board 5 fluffier and to remove the debris in the fiber fluff 51, the combing roller 34 is rotated by the combing roller drive motor 32. The comb 341 on the combing roller 34 combs the fiber fluff 51 on the surface of the decorative wood board 5 to make it fluffier.

[0044] In addition, since the carding roller 34 has a hollow mesh structure, a negative pressure fan 33 is provided on the top of the carding guide hood 35, and a filter element 31 is provided at the air outlet of the negative pressure fan 33. Specifically, the carding roller 34 generates negative pressure during the carding process of carding the fiber fluff 51 on the surface of the decorative wood board 5, which sucks the decorative wood board 5 and the debris on the carding roller 34 into the carding guide hood 35. The debris is sucked into the negative pressure fan 33 along the carding guide hood 35 and enters the filter element 31 along the negative pressure fan 33. The air is discharged through the filter element 31, and the debris remains in the filter element 31. The debris can finally be discharged from the waste plug 311 on the filter element 31, making the surface of the decorative wood board 5 cleaner and the fiber fluff 51 on the surface of the decorative wood board 5 fluffier.

[0045] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, both ends of the grinding plate 21 are provided with a traveling mechanism 4. The traveling mechanism 4 includes a driving roller 43 and a driving roller housing 42. The driving roller 43 is rotatably mounted at both ends of the fixed plate 23. The surface of the driving roller 43 is provided with anti-slip teeth. The driving roller housing 42 is located outside the driving roller 43. The driving roller housing 42 is provided with a driving roller motor 41 for driving the driving roller 43 to rotate. Both ends of the driving roller 43 are provided with a second shock-absorbing bracket 44.

[0046] Specifically, in order to make the device move steadily on the decorative wood board 5, the drive roller motor 41 drives the drive roller 43 to rotate. The drive roller 43 moves along the decorative wood board 5. The anti-slip teeth on the drive roller 43 increase the gripping force of the drive roller 43 and prevent the drive roller 43 from deviating from left to right. It provides stable support force for the grinding plate 21 during the left and right swinging grinding process. The second shock-absorbing bracket 44 makes the drive roller 43 elastically contact the surface of the decorative wood board 5 and prevents hard contact with the surface of the decorative wood board 5 from squeezing and damaging the decorative wood board 5.

[0047] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, a reciprocating vibration motor 14 is provided behind the putty outlet 15, a needle-shaped vibrating rod 141 is provided on the power shaft of the reciprocating vibration motor 14, and a scraper plate 13 is provided behind the vibrating rod 141.

[0048] Specifically, putty outlet 15 applies putty paste to the decorative wood panel 5, and the putty blends with the fiber pile 51 on the decorative wood panel 5. In order to make the putty deeply blend into the bottom of the fiber pile 51 and make full contact with the surface of the decorative wood panel 5, the reciprocating vibration motor 14 drives the needle-shaped vibrating rod 141 to move up and down back and forth. The vibrating rod 141 guides the putty downward, so that the putty is fully blended into the bottom of the fiber pile 51 and makes full contact with the surface of the decorative wood panel 5.

[0049] During the reciprocating motion of the vibrating rod 141, the decorative wood panel 5 and the putty are vibrated, causing the air in the decorative wood panel 5 and the putty to be expelled upwards. The putty, after being vibrated, is then smoothed by a scraper plate 13. An angle adjuster 142 is installed on the reciprocating vibration motor 14 to adjust the vibration angle.

[0050] In one embodiment of the present invention, such as Figure 2 , Figure 3 and Figure 5 As shown, a putty scraping bracket 12 is provided at the bottom of the putty box 11, and a putty transfer pump 16 is provided at the bottom outlet of the putty box 11. The discharge end of the putty transfer pump 16 is connected to the putty outlet 15 through a putty transfer pipe 161.

[0051] Specifically, the putty scraper bracket 12 is used to support the putty box 11, and to install the putty outlet 15, reciprocating vibration motor 14, and scraper plate 13 at the bottom. The putty paste in the putty box 11 is transferred to the putty outlet 15 by the putty transfer pump 16, and the putty is spread flat on the surface of the decorative wood board 5 from the putty outlet 15.

[0052] To clearly illustrate the above embodiments, refer to Figures 1-7 The working principle of the putty scraping auxiliary device for processing decorative wood panels of the present invention is as follows:

[0053] When applying putty to the surface of the decorative wood panel 5, first fix the decorative wood panel 5 on the designated plane, then fill the putty box 11 with putty paste to complete the preparation work. During use, attach the grinding plate 21 at the bottom of the device to the decorative wood panel 5. Driven by the drive roller motor 41, the drive roller 43 rotates, moving along the decorative wood panel 5. The anti-slip teeth on the drive roller 43 increase its gripping force, preventing it from veering left or right, and providing stable support for the grinding plate 21 during the left-right swinging grinding process, allowing the grinding surface 22 to move along the fiber grain 52 direction on the decorative wood panel 5.

[0054] like Figure 7 As shown, as the device moves on the decorative wood panel 5, the grinding plate 21 and the balance pendulum 24 are driven by the opposing pendulum assembly 28 to swing left and right (relative to the direction of device movement). The grinding surface 22 grinds and loosens the fibers on the surface of the decorative wood panel 5. During this process, the cutting edge on the grinding teeth 222 travels along the decorative wood panel 5, and the left and right swinging cutting edge grinds the fibers on the surface of the decorative wood panel 5 back and forth, causing the fibers on the decorative wood panel 5 to loosen and form a structure like... Figure 7 The fiber fluff 51 shown above further polishes the surface of the decorative wood panel 5 to create a fluffy texture.

[0055] Subsequently, the carding roller drive motor 32 drives the carding roller 34 to rotate. The combs 341 on the carding roller 34 comb the fibers 51 on the surface of the decorative wood board 5, making the fibers 51 on the surface of the decorative wood board 5 fluffier. At the same time, the carding roller 34 generates negative pressure during the process of combing the fibers 51 on the surface of the decorative wood board 5, which sucks the decorative wood board 5 and the debris on the carding roller 34 into the carding guide hood 35. The debris is sucked into the negative pressure fan 33 along the carding guide hood 35 and enters the filter element 31 along the negative pressure fan 33. The air is discharged through the filter element 31, and the debris remains in the filter element 31. The debris can finally be discharged from the waste plug 311 on the filter element 31, making the surface of the decorative wood board 5 cleaner and the fibers 51 on the surface of the decorative wood board 5 fluffier.

[0056] Then, the putty box 11 discharges the putty inside to the putty outlet 15 through the putty transfer pump 16. The putty outlet 15 applies putty paste to the decorative wood panel 5, allowing the putty to fuse with the fibers 51 on the panel 5. Subsequently, a reciprocating vibration motor 14 drives a needle-like vibrating rod 141 to move up and down, guiding the putty downwards to ensure it fully fuses with the bottom of the fibers 51 and makes full contact with the surface of the decorative wood panel 5. Finally, the vibrated putty is smoothed by a scraper plate 13, completing the putty application process for the decorative wood panel 5.

[0057] In summary, the putty scraping auxiliary device for processing decorative wood panels according to this embodiment of the invention uses a surface roughening mechanism that oscillates at high frequency along a direction perpendicular to the fibers of the decorative wood panel. The grinding surface loosens the surface fibers of the decorative wood panel, forming a fluffy rough surface. Then, the putty scraping mechanism applies putty to the rough surface, and the putty and the rough surface are fully integrated. Since the rough surface and the decorative wood panel are connected, and the pitted structure of the rough surface increases the adhesion area of ​​the putty, the putty and the decorative wood panel are more tightly bonded, reducing the possibility of putty falling off later.

[0058] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
