Description

Technical Field

[0001] This invention relates to the field of surface treatment apparatus technology, and more specifically, to a surface treatment apparatus for decorative and finishing materials. Background Technology

[0002] In the field of decorative and building materials processing, the sanding of the sides of boards is a key step in ensuring product quality, especially for sides with irregular structures such as arcs, zigzags, and grooves, where traditional sanding equipment has many limitations.

[0003] Traditional panel edge sanding mechanisms often employ rigid, fixed structures, whose sanding components cannot adaptively adjust their position and angle according to the side profile. When processing irregularly shaped sides, these rigid mechanisms struggle to closely conform to the complex contours, leading to either inadequate or excessive sanding in certain areas. This results in poor surface flatness and low precision, failing to meet the detail requirements of decorative finishing. Furthermore, for hard-to-reach areas on irregularly shaped sides, such as stepped recesses or protruding edges, traditional mechanisms can only sand a single plane, requiring manual re-sanding or equipment replacement. This not only increases the number of processes and labor costs but also makes it difficult to ensure consistent sanding. Summary of the Invention

[0004] This invention provides a surface treatment device for decorative and finishing materials, which solves the technical problems in related technologies where the position and angle of the grinding components cannot be adaptively adjusted according to the side contour, and where traditional mechanisms can only perform grinding on a single plane, requiring manual secondary grinding or equipment replacement, which not only increases the process and labor costs, but also makes it difficult to ensure grinding consistency.

[0005] This invention provides a surface treatment device for decorative and finishing materials, comprising a device body, the device body including a cabinet, side supports symmetrically mounted on both sides of the cabinet, a lower conveyor belt and an upper conveyor belt mounted on the side supports, and a material movement space between the lower conveyor belt and the upper conveyor belt; and a second grinding unit, the second grinding unit including multiple sets of second motors mounted on the side supports, and a transmission shaft mounted on the output shaft of the second motors, the transmission shaft being equipped with multiple sets of variable grinding mechanisms, the variable grinding mechanisms being used for adaptive grinding of irregularly shaped sides of decorative and finishing materials.

[0006] As a further optimization of the present invention, the variable grinding mechanism includes multiple sets of first connecting discs mounted on the drive shaft, and a second connecting disc is provided outside the first connecting disc. A variable traction member is provided between the first connecting disc and the second connecting disc, and a grinding disc is provided on the second connecting disc.

[0007] As a further optimization of the present invention, the variable traction component includes multiple sets of sleeves rotatably connected to the first connecting plate via a rotating shaft. A movable rod is slidably connected inside the sleeve, and the movable rod is rotatably connected to the second connecting plate via a rotating shaft. A first spring is installed between the sleeve and the movable rod.

[0008] As a further optimization of the present invention, a floating mechanism is provided between the transmission shaft and the output shaft of the second motor. The floating mechanism is used to control the variable sanding mechanism to float up and down, and to simultaneously sand the upper and lower dead corner areas of the irregular side of the decorative board.

[0009] As a further optimization of the present invention, the floating mechanism includes a fixed seat mounted on a second motor, a spline shaft bearing connected to the fixed seat, and the spline shaft being fixedly connected to the output shaft of the second motor. A bushing is slidably connected to the outside of the spline shaft, and a boss is mounted on the bushing. The boss is fixedly connected to the transmission shaft.

[0010] As a further optimization of the present invention, an annular guide rail is installed on the fixed base, and multiple sets of connecting columns are installed on the bushing, with the connecting columns in contact with the annular guide rail.

[0011] As a further optimization of the present invention, the boss has a slot inside for the spline shaft to move.

[0012] As a further optimization of the present invention, a roller is slidably connected on the annular guide rail, and the roller and the connecting column are rotatably connected by a bearing.

[0013] As a further optimization of the present invention, the annular guide rail is provided with multiple sets of protruding sections, and the upper surfaces of the annular guide rail and the protruding sections are provided with grooves, the size of which is adapted to the roller.

[0014] As a further optimization of the present invention, a second spring is provided on the spline shaft, and the two ends of the second spring are fixedly connected to the fixed seat and the bushing, respectively.

[0015] The beneficial effects of this invention are as follows: The variable grinding mechanism of this invention achieves multi-directional displacement compensation through a variable traction component. When contacting irregularly shaped sides, it can automatically adjust its position and angle according to contour changes, ensuring that the grinding disc is always in close contact with the side surface, thus solving the problem of poor adaptability of traditional rigid mechanisms to complex contours. Furthermore, by cooperating with a floating mechanism, the variable grinding mechanism adapts to irregularly shaped contours in the horizontal direction while simultaneously achieving up-and-down reciprocating floating with the help of the floating mechanism. This drives the grinding disc to simultaneously grind the dead corner areas at the upper and lower positions of the side, eliminating the need for manual secondary grinding and improving processing efficiency and consistency.

Detailed Implementation

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] according to Figure 1 and Figure 2 As shown, a surface treatment device for decorative and finishing materials includes: The device body 100 includes a cabinet 110. Side supports 120 are symmetrically mounted on both sides of the cabinet 110. A lower conveyor belt 130 and an upper conveyor belt 140 are mounted on the side supports 120, with a material movement space between the lower and upper conveyor belts 130 and 140. The lower conveyor belt 130 is longer than the upper conveyor belt 140, facilitating the carrying and conveying of the material to be ground. In this embodiment, the lower conveyor belt 130 primarily bears the function of carrying and conveying the material to be ground, while the upper conveyor belt 140 assists in achieving stable material feeding.

[0020] according to Figure 3 As shown, the first grinding unit 200 includes grinding rollers 210 disposed on the upper and lower sides of the plate moving space. A connecting shaft 220 is installed on the grinding roller 210, and the connecting shaft 220 passes through the side bracket 120 and is connected to the side bracket 120 bearing. Transmission gears 230 are installed on the two sets of connecting shafts 220, and the transmission gears 230 are meshed with each other. A first motor 240 is installed on one set of side brackets 120, and the output shaft of the first motor 240 is connected to one set of connecting shafts 220 through a belt pulley transmission mechanism 250.

[0021] It is important to understand that the symmetrically arranged grinding rollers 210 can grind the upper and lower surfaces of the board simultaneously, solving the efficiency bottleneck of traditional single-sided grinding. The transmission gears 230 mesh to achieve reverse synchronous operation, ensuring uniform grinding pressure, avoiding deformation of the board due to uneven force, and improving surface flatness.

[0022] according to Figure 4 and Figure 5 As shown, the second grinding unit 300 includes multiple sets of second motors 310 mounted on the side bracket 120, and a transmission shaft 320 is provided at the output shaft of the second motor 310. Multiple sets of variable grinding mechanisms 330 are provided on the transmission shaft 320. The variable grinding mechanism 330 is used to perform adaptive grinding on the irregular side of the decorative board.

[0023] It should be noted that the variable sanding mechanism 330 is designed for irregularly shaped sides, breaking through the limitations of traditional fixed grinding tools in adapting to complex contours. It can adapt to side structures with different curvatures and concave and convex shapes, expanding the applicability of the device. Multiple sets of variable sanding mechanisms 330 working in parallel can cover the entire side of the plate, ensuring processing consistency.

[0024] In summary, by integrating conveying and multi-directional grinding functions, a unified operation for surface treatment of sheet materials is achieved, reducing process changeover time and significantly improving processing efficiency. The coordinated design of the lower conveyor belt 130 and the upper conveyor belt 140 with the first grinding unit 200 and the second grinding unit 300 ensures that the sheet material completes multi-faceted processing during continuous conveying, reducing manual intervention costs.

[0025] The working principle in this embodiment is that the plate to be polished is placed on the lower conveyor belt 130 and enters the plate movement space with the driving force of the lower conveyor belt 130. The upper conveyor belt 140 assists in clamping the plate to ensure that it moves stably in the horizontal direction, providing a positioning reference for the subsequent polishing process.

[0026] After the first motor 240 starts, it drives a set of connecting shafts 220 to rotate through the belt pulley transmission mechanism 250. Because the transmission gears 230 on the two sets of connecting shafts 220 mesh with each other, the other set of connecting shafts 220 rotates synchronously in opposite directions, thereby driving the upper and lower grinding rollers 210 to rotate in opposite directions. When the board passes through the area of ​​the grinding rollers 210, the upper and lower surfaces are simultaneously subjected to grinding action, completing the flat surface treatment.

[0027] At the same time, the surface-treated board is simultaneously polished by the second polishing unit 300. The second motor 310 drives the variable polishing mechanism 330 to operate through the transmission shaft 320. The contact angle and pressure are automatically adjusted according to the irregular contour of the side of the board. Through the parallel cooperation of multiple sets of variable polishing mechanisms 330, the side area is fully covered, and the precise polishing of the irregular structure is achieved.

[0028] In one embodiment, according to Figure 6 and Figure 7 As shown, the variable polishing mechanism 330 includes multiple sets of first connecting discs 331 mounted on the drive shaft 320, and a second connecting disc 332 is provided on the outside of the first connecting disc 331. End caps 338 are installed on both the upper and lower sides of the second connecting disc 332. A variable traction member is provided between the first connecting disc 331 and the second connecting disc 332. A polishing disc 336 is provided on the second connecting disc 332.

[0029] Multiple sets of bolts 337 are installed between the grinding disc 336 and the second connecting disc 332, and these bolts 337 pass through the grinding disc 336 and are threadedly connected to the second connecting disc 332. This bolt 337 connection structure allows for quick disassembly and replacement of the grinding disc 336, facilitating the selection of abrasive discs with different grit sizes and hardnesses according to the material of the sheet or the required grinding precision, thus enhancing the versatility of the device. Furthermore, the worn grinding disc 336 can be replaced individually, reducing equipment maintenance costs.

[0030] In yet another embodiment, according to Figure 7As shown, the variable traction component includes multiple sets of sleeves 333 that are rotatably connected to the first connecting plate 331 via a rotating shaft. A movable rod 334 is slidably connected inside the sleeve 333, and the movable rod 334 is rotatably connected to the second connecting plate 332 via a rotating shaft. A first spring 335 is installed between the sleeve 333 and the movable rod 334.

[0031] Specifically, the variable traction component, through the sliding engagement of the sleeve 333 and the movable rod 334, combined with the elastic potential energy of the first spring 335, enables the second connecting plate 332 to perform multi-directional displacement compensation relative to the first connecting plate 331.

[0032] When the grinding disc 336 contacts the irregular side, it can automatically adjust its position and angle according to the contour change, ensuring that the grinding disc 336 is always in close contact with the side surface, thus solving the problem of poor adaptability of traditional rigid grinding mechanisms to complex contours.

[0033] Furthermore, the first spring 335 not only provides driving force for adaptive adjustment, but also absorbs impact energy when the grinding disc 336 encounters hard points or sudden loads, preventing damage to the grinding disc 336 or the surface of the plate due to instantaneous overload, thus playing a buffering and protective role; multiple sets of variable traction components are evenly distributed to ensure the force balance of the second connecting disc 332, preventing swaying during grinding and improving processing accuracy.

[0034] The working principle in this embodiment is that the second motor 310 drives the transmission shaft 320 to rotate, and the transmission shaft 320 drives the first connecting plate 331 to rotate synchronously. Through the linkage of the variable traction component, the second connecting plate 332 rotates with the first connecting plate 331, thereby driving the grinding plate 336 to rotate at high speed and forming grinding kinetic energy.

[0035] When the irregular side of the board enters the grinding area, the grinding disc 336 contacts the side surface and is subjected to the contour reaction force.

[0036] If the side protrudes outward, the movable rod 334 compresses the first spring 335 and retracts into the sleeve 333, causing the second connecting plate 332 to move closer to the first connecting plate 331; if the side is recessed inward, the restoring force of the first spring 335 pushes the movable rod 334 out of the sleeve 333, causing the second connecting plate 332 to expand outward.

[0037] Meanwhile, the sleeve 333 and the movable rod 334 can rotate at multiple angles through the rotating shaft, ensuring that the grinding disc 336 always matches the side tangent direction, so as to achieve close grinding of complex contours such as curved surfaces and broken lines.

[0038] In yet another embodiment, according to Figure 4 , Figure 5 and Figure 8As shown, a floating mechanism 340 is provided between the transmission shaft 320 and the output shaft of the second motor 310. The floating mechanism 340 is used to control the variable grinding mechanism 330 to float up and down while performing adaptive grinding on the irregular edge, so as to perform synchronous grinding on the dead corner area at the upper and lower positions.

[0039] Specifically, the floating mechanism 340 includes a fixed seat 341 mounted on the second motor 310, a splined shaft 342 connected to the fixed seat 341 by a bearing, and the splined shaft 342 is fixedly connected to the output shaft of the second motor 310. A bushing 343 is slidably connected to the outside of the splined shaft 342, and a boss 344 is mounted on the bushing 343. The boss 344 is fixedly connected to the transmission shaft 320.

[0040] The boss 344 has a slot inside for the spline shaft 342 to move, which makes it easier to provide space for the spline shaft 342.

[0041] Furthermore, according to Figure 8 As shown, a ring guide rail 345 is installed on the fixed base 341, and multiple sets of connecting columns 347 are installed on the bushing 343. Rollers are slidably connected to the ring guide rail 345, and the rollers and connecting columns 347 are rotatably connected by bearings.

[0042] In this embodiment, the sliding fit between the spline shaft 342 and the bushing 343 ensures efficient transmission of rotational power and allows the bushing 343 to move freely along the axial direction. The guiding effect of the annular guide rail 345 and the roller constrains the floating trajectory of the bushing 343, prevents swaying, and ensures the positioning accuracy of the variable grinding mechanism 330 during up and down movement.

[0043] The annular guide rail 345 is provided with multiple sets of protruding sections 346. The annular guide rail 345 and the protruding sections 346 are integrally formed. The upper surfaces of the annular guide rail 345 and the protruding sections 346 are provided with grooves, and the size of the grooves is adapted to the rollers.

[0044] It should be noted that a second spring 348 is provided on the spline shaft 342, and the two ends of the second spring 348 are fixedly connected to the fixed seat 341 and the bushing 343 respectively.

[0045] The protruding section 346 of the annular guide rail 345, in conjunction with the roller, causes the bushing 343 to undergo periodic up-and-down displacement as it rotates with the splined shaft 342, thereby driving the transmission shaft 320 and the variable grinding mechanism 330 to float up and down. This design breaks through the limitations of traditional horizontal grinding, and can simultaneously process the dead corners of the upper and lower edges of the board, such as stepped or recessed shapes, avoiding secondary rework and improving the integrity of grinding irregular edges.

[0046] The working principle in this embodiment is that after the second motor 310 is started, the output shaft drives the spline shaft 342 to rotate. Since the spline shaft 342 and the bushing 343 are connected by splines, the bushing 343 rotates synchronously with the spline shaft 342, and then drives the transmission shaft 320 and the variable grinding mechanism 330 to rotate through the boss 344, so as to maintain the cutting motion required for grinding.

[0047] When the bushing 343 rotates, the connecting post 347 drives the roller to slide along the groove of the annular guide rail 345. When the roller contacts the protruding section 346, the height difference of the protruding section 346 forces the roller to move upward, pushing the bushing 343 axially upward along the spline shaft 342 through the connecting post 347, compressing the second spring 348. When the roller disengages from the protruding section 346, the restoring force of the second spring 348 pushes the bushing 343 downward, and the roller returns to the guide rail plane. This process repeats with the rotation cycle, realizing the up-and-down reciprocating floating of the variable grinding mechanism 330.

[0048] Driven by the floating mechanism 340, the variable grinding mechanism 330 adapts to the horizontal contour of the irregular edge through its own variable traction component, and covers the vertical height difference area by floating up and down.

[0049] In other embodiments, according to Figure 1 As shown, the surface treatment device also includes a connecting frame 150, which is mounted on the cabinet 110. Multiple dust removal pipes 400 are installed on the connecting frame 150. Each dust removal pipe 400 is equipped with an exhaust pipe, which is connected to an external dust removal device. The dust removal pipe 400 has a dust suction port at one end near the grinding roller 210.

[0050] Specifically, when the first grinding unit 200 of the device is working, the grinding roller 210 grinds the material to be processed, generating a large amount of dust and debris. At this time, the external dust removal equipment is activated, creating a negative pressure in the dust removal pipe 400 through the exhaust pipe. Since the dust suction port of the dust removal pipe 400 is close to the grinding roller 210, under the action of negative pressure, the dust and debris generated during grinding are sucked into the dust suction port, and then enter the external dust removal equipment along the dust removal pipe 400 and the exhaust pipe. The external dust removal equipment collects and processes the dust and debris, thereby achieving effective dust removal in the grinding area.

[0051] It should be noted that the cabinet 110 is also equipped with a connecting pipe, which is also connected to an external dust removal device. When sanding the decorative panels, the cabinet 110 and the decorative panels are formed in a relatively enclosed space by the shielding effect during the transport of the decorative panels, which facilitates the extraction of sanding debris and dust.

[0052] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
