Description

Technical Field

[0001] The invention relates to the technical field of plate surface treatment, and in particular to a flat-coated finishing coating device and a method thereof. Background Art

[0002] Flat-covered finishing coating is a process of evenly bonding decorative materials to the surface of the board through glue. This coating is not only beautiful, but also enhances the durability and texture of the board. In the process of covering the board with wood veneer, applying glue is a crucial step, which can ensure that the two are tightly and firmly combined. However, before applying glue, the dust on the surface of the board must be strictly removed. This is because the dust will interfere with the bonding effect of the glue, resulting in loose coating, and even bubbling, falling off and other problems.

By setting the above structure, the coating equipment has the advantage of convenient conveying and loading when in use, thereby being able to meet the customer's usage needs.

[0004] When replacing the dust-collecting roll paper, the existing flat-covering finishing coating equipment often needs to stop the machine for operation to ensure the safety of the workers, which will lead to the disruption of the continuity of the coating process.

Two parallel limiting grooves 121 that pass through the left and right sides are opened on the outer wall of the supporting frame plate 120. Limiting holes 122 are opened at the upper and lower ends of the groove wall at one end of the limiting groove 121. An outer convex plate 130 is welded on the outer wall of one of the supporting frame plates 120.

[0022] Furthermore, the fixed frame 110 and the supporting frame plate 120 are used to ensure the strength of the overall structure of the supporting device 100, the limiting slide groove 121 is used to limit the moving 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 convex plate 130 is used to provide a placement platform for the structure in the gluing device 200.

A glue storage tank 250 is provided above the outer jacket bin 240, and its two ends are fixedly connected between the two supporting frame plates 120 by bolts. A plurality of feeding pipes 260 are connected between the glue storage tank 250 and the outer jacket bin 240.

[0024] Furthermore, after the driving motor 210 is turned on, it drives the rotating shaft 220 to rotate, and drives the glue coating roller 230 to rotate inside the outer jacket bin 240. The finishing glue in the glue storage tank 250 is then fed into the inner part of the outer jacket bin 240 through the feeding pipe 260, and evenly adheres to the outer wall of the glue coating roller 230.

[0025] In this embodiment, Figure 6 As shown, the transmission device 300 includes a reciprocating screw 310 that rotates as the rotating shaft 220 rotates, and a moving toothed plate 320 that reciprocates back and forth as the reciprocating screw 310 rotates; Specifically, the front and rear ends of the reciprocating screw rod 310 are respectively rotatably connected to the inner side walls of the front and rear ends of the support frame plate 120, the movable tooth plate 320 is threadedly connected to the outer side of the reciprocating screw rod 310, and the movable tooth plate 320 is slidably connected to the top surface of the support frame plate 120.

[0026] 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 clamped and fixed to the outer wall of the reciprocating screw 310, and a transmission belt 330 with both ends sleeved on the center rod of the main bevel gear 340 and the outer wall of the rotating shaft 220, and the main bevel gear 340 is meshed with the secondary bevel gear 350.

[0027] Furthermore, the power of the rotating shaft 220 is transmitted through the transmission belt 330, which then drives the main bevel gear 340 to rotate, and drives the secondary bevel gear 350 to rotate, and then the reciprocating screw 310 rotates together, so that the movable tooth plate 320 moves back and forth on the top surface of the support frame plate 120.

[0028] In this embodiment, Figure 7 As shown, the roller changing device 400 includes a connecting rod 410, rod end gears 420 arranged at both ends, a docking gear 430 that rotates as the rod end gear 420 rotates, a toggle rod 440 whose inclination angle changes as the docking gear 430 rotates, and a limiter 450 that moves as the end position of the toggle rod 440 changes; Specifically, the left and right ends of the connecting rod 410 are clamped and fixed on the inner walls of the two supporting frame plates 120, the rod end gear 420 is rotatably connected to the outer wall of the connecting rod 410, the rod end gear 420 is meshed with the rack on the bottom surface of the movable gear plate 320, the docking gear 430 is meshed with the rod end gear 420 and is clamped and fixed on the outer wall of the center rod of the outer wall of the toggle rod 440, the toggle rod 440 is rotatably connected to the inner wall of the supporting frame plate 120 through the center rod of the outer wall, and the front and rear ends of the toggle rod 440 are provided with a rod body slide groove 441.

[0029] Furthermore, during the movement of the movable tooth plate 320, after contacting with the rod end gear 420, it drives the rod end gear 420 to rotate, and drives the docking gear 430 to rotate, thereby changing the inclination angle of the toggle 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 toggle rod 440 is used to cooperate with the limiting groove 121 to limit the overall movement range of the limiting part 450.

[0030] In this embodiment, Figure 8 As shown, the limiting part 450 includes two limiting sliders 451 arranged in parallel and slidably connected to the inside of the limiting slide groove 121, a fixing rod 452 clamped between the two limiting sliders 451, a plurality of first pressure springs 453 arranged inside the limiting sliders 451 close to the outside, and a limiting protrusion 454 arranged at the end position of the first pressure spring 453. The fixing rod 452 passes through the inside of the rod body slide groove 441, and the end of the limiting protrusion 454 extends to the inside of the limiting hole 122 under the elastic force of the first pressure spring 453. Furthermore, the inner limit slider 451 is used to provide a fixed base point for the internal structure of the dust removal device 500, and a circular hole for placing the limit slider 451 is opened inside the outer limit slider 451. When the outer limit slider 451 moves to the end position of the limit slide groove 121, the limit protrusion 454 will extend to the inside of the limit hole 122 under the elastic force of the first pressure spring 453, so as to limit the position of the limit slider 451, thereby ensuring that the position of the toggle rod 440 can remain stable when the rod end gear 420 does not rotate.

[0031] In this embodiment, Fig. 9 As shown, the dust removal device 500 includes two parallel butt joint plates 510, a mounting plate 520 disposed below the butt joint plates 510, and a dust collecting roller 530 disposed between the two mounting plates 520; Specifically, the docking plate 510 is fixedly connected to the docking plate 510 on the outer wall of the inner limiting slider 451 by screws, and the two ends of the dust collecting roller 530 are clamped and fixed between the two mounting plates 520. The dust removal device 500 also includes a plurality of limiting telescopic rods 540 connected between the docking plate 510 and the mounting plate 520 and a second pressure spring 550 mounted on the outside of the limiting telescopic rods 540.

[0032] Furthermore, one end of the limiting telescopic rod 540 is clamped on the bottom surface of the docking plate 510, and the other end is clamped on the top surface of the mounting plate 520, and the increased elastic force of the second pressure spring 550 pushes the mounting plate 520 to move downward.

[0033] Furthermore, the docking plate 510 cooperates with the limiting telescopic rod 540 to provide a mounting 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, and contracts when the dust collecting roller 530 contacts the surface of the plate. The elastic potential energy generated is immediately converted into the force of the dust collecting roller 530 on the surface of the plate. The dust collecting roller 530 then adheres to the dust on the surface of the plate through the outer dust collecting paper roll. Multiple layers of dust collecting paper rolls are wound around the outer side of the dust collecting roller 530. When the adhesion of the outermost dust collecting roller 530 is reduced, a piece of dust collecting paper roll on the surface can be directly torn off.

[0034] The flat-coated finishing coating method of the present invention comprises the following steps: S1. First, start the sheet conveying mechanism, and place the sheet on it through the robot, so that the sheet moves toward the gluing device 200; S2. Subsequently, the driving motor 210 in the glue coating device 200 is turned on to drive the rotating shaft 220 to rotate, thereby driving the glue coating roller 230 to rotate inside the outer jacket bin 240. The finishing glue in the glue storage tank 250 is then fed into the inner part of the outer jacket bin 240 through the feeding pipe 260 and evenly adheres to the outer side wall of the glue coating roller 230. S3. At this time, the driving force of the rotating shaft 220 is transmitted through the transmission belt 330, which then drives the main bevel gear 340 to rotate, and drives the secondary bevel gear 350 to rotate, and then the reciprocating screw rod 310 rotates together, so that the movable tooth plate 320 moves forward and backward on the top surface of the supporting frame plate 120; S4, during the movement of the movable toothed plate 320, after contacting with the rod end gear 420, the rod end gear 420 is driven to rotate, and the docking gear 430 is driven to rotate, thereby changing the tilt angle of the toggle rod 440; S5. At this time, the limiting part 450 as a whole is displaced inside the limiting slide groove 121 and the rod slide groove 441, so that the relative positions of the pair of dust removal devices 500 are changed, so that the dust collecting roller 530 in one of the dust removal devices 500 is in contact with the surface of the plate, while the dust collecting roller 530 in the other dust removal device 500 is away from the surface of the plate; S6. After that, the fine dust on the surface of the plate is cleaned by the dust collecting roller 530, and then the plate conveying mechanism moves to the bottom of the glue coating roller 230, and the glue coating roller 230 applies glue on the surface of the plate; S7. Subsequently, the board coated with glue enters the interior of the covering machine, the veneer is adhered to the outside of the board, and after mechanical trimming, it is taken out by the robot at the end of the board conveying mechanism.

[0035] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.

The flat-covered finishing coating equipment according to claim 7 is characterized in that: The docking plate (510) is fixedly connected to the docking plate (510) on the outer side wall of the inner limiting slider (451) by means of screws, and the two ends of the dust collecting roller (530) are clamped and fixed between the two mounting plates (520). The dust removal device (500) further comprises a plurality of limiting telescopic rods (540) connected between the docking plate (510) and the mounting plate (520), and a second pressure spring (550) sleeved on the outer side of the limiting telescopic rods (540).

9. The flat-covered finishing coating equipment according to claim 8 is characterized in that: One end of the position-limiting telescopic rod (540) is clamped on the bottom surface of the docking plate (510), and the other end is clamped on the top surface of the mounting plate (520), and the increased elastic force of the second pressure spring (550) pushes the mounting plate (520) to move downward.

10. A flat-coated surface coating method, using the flat-coated surface coating equipment according to claim 9, characterized in that: The following steps are involved: S1. First, start the sheet conveying mechanism and place the sheet on it through a robot, so that the sheet moves toward the gluing device (200); S2. Subsequently, the driving motor (210) in the glue coating device (200) is turned on to drive the rotating shaft (220) to rotate, thereby driving the glue coating roller (230) to rotate inside the outer jacket bin (240). The finishing glue in the glue storage tank (250) is then fed into the inner part of the outer jacket bin (240) through the feeding pipe (260) and evenly adheres to the outer side wall of the glue coating roller (230); S3. At this time, the power of the rotation of the rotating shaft (220) is transmitted through the transmission belt (330), which then drives the main bevel gear (340) to rotate, and drives the secondary bevel gear (350) to rotate, and then causes the reciprocating screw (310) to rotate together, so that the movable tooth plate (320) is displaced forward and backward on the top surface of the supporting frame plate (120); S4, during the movement of the movable toothed plate (320), after contacting with the rod end gear (420), the rod end gear (420) is driven to rotate, and the docking gear (430) is driven to rotate, thereby changing the tilt angle of the toggle rod (440); S5. At this time, the limiting portion (450) as a whole is displaced inside the limiting sliding groove (121) and the rod sliding groove (441), so that the relative positions of the pair of dust removal devices (500) are changed, so that the dust collecting roller (530) in one of the dust removal devices (500) is in contact with the surface of the plate, while the dust collecting roller (530) in the other dust removal device (500) is away from the surface of the plate; S6. Afterwards, the fine dust on the surface of the plate is cleaned by the dust collecting roller (530), and then the plate conveying mechanism moves the plate to the bottom of the glue coating roller (230), and the glue coating roller (230) coats the surface of the plate with glue; S7. Subsequently, the board coated with glue enters the interior of the covering machine, the veneer is adhered to the outside of the board, and after mechanical trimming, it is taken out by the robot at the end of the board conveying mechanism.
