Description

Technical Field

[0001] This invention relates to the field of surface treatment technology for sheet materials, and more specifically, to a flat-coating decorative coating device and method. Background Technology

[0002] Flat-mount finish coating is a process in which decorative materials are smoothly bonded to the surface of a board using adhesive. This coating is not only aesthetically pleasing but also enhances the durability and texture of the board. In the process of bonding the board and the wood veneer, the application of adhesive is a crucial step, ensuring a tight and firm bond between the two. However, before applying the adhesive, it is essential to thoroughly remove dust from the surface of the board, as dust can interfere with the adhesive's bonding effect, leading to an insecure coating or even problems such as bubbling and peeling.

[0003] Patent application number CN202321100368.6 discloses a flat-coating surface coating equipment, including a box body. The top of the inner cavity of the box body is rotatably connected to a rotating shaft via a bearing. A turntable is fixedly connected to the bottom of the rotating shaft. The top of the turntable has a ring-shaped placement groove. A filter screen is embedded in the bottom of the placement groove in a ring shape. Each of the four corners of the top of the filter screen is fixedly connected to a support plate. A drive assembly is fixedly installed on the right side of the top of the box body. With the above structure, the coating equipment has the advantage of convenient material feeding during use, thereby meeting the needs of customers.

[0004] Existing flat-coating equipment often requires machine shutdown when changing dust-laden rolls to ensure worker safety, which disrupts the continuity of the coating process. Furthermore, changing dust-laden rolls requires manual intervention of the dust removal device, a cumbersome and time-consuming process that increases operational complexity.

[0005] In view of this, we propose a flat-applied coating equipment and method for decorative coating. Summary of the Invention

[0016] In the technical solution of the present invention, the front and rear ends of the reciprocating lead screw are respectively rotatably connected to the inner sidewalls of the front and rear ends of the support frame plate, the movable tooth plate is threadedly connected to the outer side of the reciprocating lead screw, and the movable tooth plate is slidably connected to the top surface of the support frame plate.

[0017] In the technical solution of the present invention, the transmission device further includes a secondary bevel gear rotatably connected to the outer wall of the support frame plate, a secondary bevel gear snapped and fixed to the outer wall of the reciprocating screw, and a transmission belt with both ends sleeved on the central rod of the main bevel gear and the outer wall of the rotating shaft, wherein the main bevel gear meshes with the secondary bevel gear.

[0018] In the technical solution of the present invention, the left and right ends of the connecting rod are snapped and fixed to the inner sidewalls of the two support frame plates, the rod end gear is rotatably connected to the outer sidewall of the connecting rod, the rod end gear meshes with the rack on the bottom surface of the movable tooth plate, the mating gear meshes with the rod end gear and is snapped and fixed to the outer sidewall of the center rod of the outer sidewall of the actuating rod, the actuating rod is rotatably connected to the inner sidewall of the support frame plate through the center rod of the outer sidewall, and rod body sliding grooves are provided at both the front and rear ends of the actuating rod.

[0019] In the technical solution of the present invention, the limiting part includes two parallel limiting sliders slidably connected inside the limiting groove, a fixing rod snapped between the two limiting sliders, a plurality of first pressure springs disposed inside the limiting sliders on the outer side, and a limiting protrusion disposed at the end of the first pressure spring.

[0021] In the technical solution of the present invention, one end of the limiting telescopic rod is engaged with the bottom surface of the docking plate and the other end is engaged with the top surface of the mounting plate, and the elastic force increased by the second pressure spring pushes the mounting plate to move downward.

[0022] On the other hand, the present invention also provides a method for applying a decorative coating by flat application, comprising the following steps:

[0023] S1. First, start the board conveying mechanism and place the board on it using a robotic arm, allowing the board to move towards the gluing device;

[0024] S2. Then, turn on the drive motor in the glue application device to drive the rotating shaft to rotate, which in turn drives the glue application roller to rotate inside the outer chamber. The finishing glue in the storage tank is then fed into the inner chamber through the feeding pipe and evenly adheres to the outer wall of the glue application roller.

[0025] S3. At this time, the power of the rotating shaft is transmitted through the transmission belt, which drives the main bevel gear to rotate, and then drives the secondary bevel gear to rotate, which in turn causes the reciprocating screw to rotate, thereby causing the moving toothed plate to move back and forth on the top surface of the support frame plate.

[0026] S4. During the movement of the moving toothed plate, after contacting the gear at the end of the rod, it causes the gear at the end of the rod to rotate, which in turn causes the mating gear to rotate, thereby changing the tilt angle of the lever.

[0027] S5. At this time, the limiting part moves inside the limiting slide groove and the rod slide groove, thereby changing the relative position of the pair of dust removal devices, so that the dust-adhesive roller in one of the dust removal devices comes into contact with the surface of the plate, while the dust-adhesive roller in the other dust removal device moves away from the surface of the plate.

[0028] S6. After that, the fine dust on the surface of the board is cleaned by the dust-adhesive roller and then moved by the board conveying mechanism to the bottom of the glue-applying roller, where glue is applied to the surface of the board.

[0029] S7. Subsequently, the boards coated with glue enter the inside of the wrapping machine, where the wood veneer is adhered to the outside of the boards. After mechanical trimming, the boards are removed by the robotic arm at the end of the board conveying mechanism.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. The flat-coating finishing equipment and method, after long-term operation, when it is necessary to remove the dust-adhesive paper roll on the dust-adhesive roller to improve the dust removal effect, can allow two dust removal devices to contact the surface of the board by changing the tilt angle of the toggle lever. The operator can then remove the outer dust-adhesive paper roll without stopping the machine, thereby improving the convenience of the work and ensuring the continuity of the coating process.

[0032] 2. The flat-applied coating equipment and method, in which the drive motor drives the coating roller to rotate inside the outer casing, and through the transmission device, the moving toothed plate reciprocates, thereby changing the tilt angle of the lever, improves the overall automation of the device while reducing the investment in additional drive equipment.

[0048] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0049] Please see Figures 1-9 As shown, this embodiment provides a technical solution:

[0050] A flat-applied coating equipment includes a set of support devices 100 symmetrically arranged on both sides of a sheet material conveying mechanism, an adhesive applicator 200 arranged between the support devices 100, a transmission device 300 that moves with the internal structure of the adhesive applicator 200, a roller changing device 400 arranged in front of the adhesive applicator 200, and a set of dust removal devices 500 arranged below the roller changing device 400.

[0051] In this invention, the support device 100 includes a fixed frame 110 and a support frame plate 120 disposed on the top surface of the fixed frame 110;

[0052] Specifically, the fixed frame 110 is fixedly connected to the outer wall of the brackets at both ends of the plate conveying mechanism by bolts. The support frame plate 120 is welded and fixed to the top surface of the fixed frame 110. Two parallel and through-flow limiting grooves 121 are provided on the outer wall of the support frame plate 120. Limiting holes 122 are provided at both the upper and lower ends of one end of the groove wall of the limiting groove 121. An outward protruding plate 130 is welded on the outer wall of one of the support frame plates 120.

[0053] Furthermore, the fixed frame 110 and the support frame plate 120 are used to ensure the overall structural strength of the support device 100, the limiting slide groove 121 is used to limit the movement range of the internal device of the roller changing device 400, the limiting hole 122 is used to limit the fixed position of the internal device of the roller changing device 400, and the outer protruding plate 130 is used to provide a placement platform for the structure in the glue coating device 200.

[0054] In this embodiment, as Figure 5 As shown, the glue application device 200 includes a drive motor 210, a rotating shaft 220 disposed on the output shaft of the drive motor 210, a glue application roller 230 that rotates with the rotating shaft 220, and an outer sleeve 240 sleeved on the outside of the glue application roller 230.

[0055] Specifically, the drive motor 210 is fixedly connected to the top surface of the outer protrusion plate 130 by bolts, the rotating shaft 220 is coaxially connected to the output shaft of the drive motor 210, the glue-applying roller 230 is fixedly connected to the outer wall of the rotating shaft 220 by a snap pin, the glue-applying roller 230 is rotatably connected to the inside of the outer casing 240, the two ends of the outer casing 240 are fixedly connected between two support frame plates 120 by bolts, a glue storage tank 250 is provided above the outer casing 240 and the two ends are fixedly connected between the two support frame plates 120 by bolts, and several feeding pipes 260 are connected between the glue storage tank 250 and the outer casing 240.

[0056] Furthermore, after the drive motor 210 is turned on, it drives the rotating shaft 220 to rotate, which in turn drives the coating roller 230 to rotate inside the outer casing 240. The finishing adhesive in the storage tank 250 is then fed into the outer casing 240 through the feeding pipe 260 and evenly adheres to the outer wall of the coating roller 230.

[0057] In this embodiment, as Figure 6 As shown, the transmission device 300 includes a reciprocating lead screw 310 that rotates with the rotating shaft 220 and a moving gear plate 320 that moves back and forth as the reciprocating lead screw 310 rotates.

[0058] Specifically, the front and rear ends of the reciprocating screw 310 are rotatably connected to the inner sidewalls of the front and rear ends of the support frame plate 120, respectively. The movable toothed plate 320 is threadedly connected to the outer side of the reciprocating screw 310 and slidably connected to the top surface of the support frame plate 120.

[0059] Furthermore, the transmission device 300 also includes a secondary bevel gear 350 rotatably connected to the outer wall of the support frame plate 120, a secondary bevel gear 350 snapped and fixed to the outer wall of the reciprocating screw 310, and a transmission belt 330 with both ends sleeved on the outer wall of the central rod of the main bevel gear 340 and the outer wall of the rotating shaft 220, wherein the main bevel gear 340 meshes with the secondary bevel gear 350.

[0060] Furthermore, the power to rotate the rotating shaft 220 is transmitted through the transmission belt 330, which in turn drives the main bevel gear 340 to rotate, and drives the secondary bevel gear 350 to rotate, thereby causing the reciprocating screw 310 to rotate as well, so that the moving toothed plate 320 moves back and forth on the top surface of the support frame plate 120.

[0061] In this embodiment, as Figure 7 As shown, the roller changing device 400 includes a connecting rod 410, rod end gears 420 disposed at both ends, a docking gear 430 that rotates with the rod end gear 420, a lever 440 whose tilt angle changes with the rotation of the docking gear 430, and a limiting part 450 that is displaced with the change of the end position of the lever 440.

[0062] Specifically, the left and right ends of the connecting rod 410 are snapped and fixed to the inner sidewalls of the two support frame plates 120. The rod end gear 420 is rotatably connected to the outer sidewall of the connecting rod 410. The rod end gear 420 meshes with the rack on the bottom surface of the movable gear plate 320. The mating gear 430 meshes with the rod end gear 420 and is snapped and fixed to the outer sidewall of the center rod of the outer sidewall of the actuating rod 440. The actuating rod 440 is rotatably connected to the inner sidewall of the support frame plate 120 through the center rod of the outer sidewall. The front and rear ends of the actuating rod 440 are provided with rod body grooves 441.

[0063] Furthermore, during the movement of the moving toothed plate 320, after contacting the rod-end gear 420, it causes the rod-end gear 420 to rotate, which in turn causes the mating gear 430 to rotate, thereby changing the tilt angle of the actuating rod 440. The connecting rod 410 is used to provide a rotation range for the rod-end gear 420, and the rod body groove 441 on the actuating rod 440 is used to cooperate with the limiting groove 121 to limit the overall movement range of the limiting part 450.

[0064] In this embodiment, as Figure 8 As shown, the limiting part 450 includes two parallel limiting sliders 451 that are slidably connected inside the limiting groove 121, a fixing rod 452 that is engaged between the two limiting sliders 451, a plurality of first pressure springs 453 disposed inside the limiting sliders 451 on the outer side, and a limiting protrusion 454 disposed at the end of the first pressure spring 453. The fixing rod 452 passes through the inside of the rod groove 441, and the end of the limiting protrusion 454 extends into the inside of the limiting hole 122 under the elastic force of the first pressure spring 453.

[0065] Furthermore, the inner limiting slider 451 is used to provide a fixed base point for the internal structure of the dust removal device 500, and the outer limiting slider 451 has a round hole for placing the limiting slider 451. When the outer limiting slider 451 moves to the end position of the limiting groove 121, the limiting protrusion 454 will extend into the interior of the limiting hole 122 under the elastic force of the first pressure spring 453, thereby limiting the position of the limiting slider 451, thus ensuring that the position of the lever 440 remains stable when the lever end gear 420 does not rotate.

[0066] In this embodiment, as Figure 9 As shown, the dust removal device 500 includes two parallel docking plates 510, a mounting plate 520 disposed below the docking plates 510, and a dust-adhesive roller 530 disposed between the two mounting plates 520.

[0067] Specifically, the docking plate 510 is fixedly connected to the outer wall of the inner limit slider 451 by screws. The two ends of the dust-adhesive roller 530 are snapped and fixed between the two mounting plates 520. The dust removal device 500 also includes several limit telescopic rods 540 connected between the docking plate 510 and the mounting plate 520, and a second pressure spring 550 sleeved on the outside of the limit telescopic rods 540.

[0068] Furthermore, one end of the limiting telescopic rod 540 is engaged with the bottom surface of the docking plate 510, and the other end is engaged with the top surface of the mounting plate 520. The increased elastic force of the second pressure spring 550 pushes the mounting plate 520 downward.

[0069] Furthermore, the docking plate 510, in conjunction with the limiting telescopic rod 540, provides an installation platform for the mounting plate 520. The elastic force provided by the second pressure spring 550 is used to push the mounting plate 520 downward. When the dust-adhesive roller 530 comes into contact with the surface of the board, it contracts, and the resulting elastic potential energy is converted into the force exerted by the dust-adhesive roller 530 on the surface of the board. The dust-adhesive roller 530 then adheres to the dust on the surface of the board through the outer dust-adhesive paper roll. Multiple layers of dust-adhesive paper rolls are wound around the outer side of the dust-adhesive roller 530. When the adhesion of the outermost dust-adhesive roller 530 decreases, the outermost dust-adhesive paper roll can be directly torn off.

[0070] The method for applying a flat-coated finish according to the present invention includes the following steps:

[0071] S1. First, start the board conveying mechanism and place the board on it using a robotic arm, so that the board moves toward the gluing device 200;

[0072] S2. Subsequently, the drive motor 210 in the glue application device 200 is turned on, which drives the rotating shaft 220 to rotate, and drives the glue application roller 230 to rotate inside the outer chamber 240. The finishing glue in the glue storage tank 250 is then fed into the outer chamber 240 through the feeding pipe 260 and evenly adhered to the outer wall of the glue application roller 230.

[0073] S3. At this time, the power of rotating shaft 220 is transmitted through transmission belt 330, which drives main bevel gear 340 to rotate, and drives secondary bevel gear 350 to rotate, which in turn causes reciprocating screw 310 to rotate, thereby causing moving tooth plate 320 to move back and forth on the top surface of support frame plate 120.

[0074] S4. During the movement of the moving toothed plate 320, after contacting the rod end gear 420, it causes the rod end gear 420 to rotate, which in turn causes the mating gear 430 to rotate, thereby changing the tilt angle of the actuating rod 440.

[0075] S5. At this time, the limiting part 450 is displaced inside the limiting slide groove 121 and the rod slide groove 441, which changes the relative position of the pair of dust removal devices 500, so that the dust-adhesive roller 530 in one of the dust removal devices 500 contacts the surface of the plate, while the dust-adhesive roller 530 in the other dust removal device 500 moves away from the surface of the plate.

[0076] S6. After that, the fine dust on the surface of the board is cleaned by the dust roller 530 and then moved by the board conveying mechanism to the bottom of the glue roller 230, where glue is applied to the surface of the board by the glue roller 230.

[0077] S7. Subsequently, the boards coated with glue enter the inside of the wrapping machine, where the wood veneer is adhered to the outside of the boards. After mechanical trimming, the boards are removed by the robotic arm at the end of the board conveying mechanism.

[0078] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations. The scope of the invention is intended to be defined by the specification and its equivalents.
