Description

Technical Field

[0001] This application relates to the field of wood processing technology, and more specifically, to a polishing apparatus for wood panels. Background Technology

[0002] In wood processing, fine polishing is often required to improve the smoothness and aesthetics of board surfaces. Currently, the industry commonly uses simultaneous polishing of both sides. While this improves efficiency to some extent, in certain applications, customers may have different polishing requirements for each side—one side might require a higher gloss, while the other needs a rougher texture. Furthermore, simultaneous polishing places extremely demanding requirements on equipment, necessitating not only a high-precision control system but also powerful motors and stability, which often makes achieving the desired results in practice difficult. Therefore, the industry urgently needs a device capable of independently polishing both sides of a board to more flexibly meet the personalized needs of different customers, lower the technical barriers to entry, improve polishing quality and efficiency, and effectively solve the aforementioned problems. Summary of the Invention

[0003] This application provides a polishing apparatus for sheet metal, including a polishing mechanism, a flipping mechanism, and a transfer conveyor belt. Two polishing mechanisms arranged in parallel are used to independently polish opposite sides of the sheet metal. Each polishing mechanism includes a polishing machine body and conveyor belt assemblies disposed at both ends of the polishing machine body. The conveyor belt assembly includes a conveyor frame, a drive motor, and multiple support rollers. The tail end of the conveyor frame is provided with a waiting area, wherein the waiting area has a notch on the side adjacent to the conveyor frame of the other polishing mechanism. The flipping mechanism is disposed in the gap at the end between the two polishing mechanisms. The flipping mechanism includes a base, a flipping frame mounted on the base, and a flipping motor that drives the flipping frame to rotate. The flipping frame includes a flipping shaft and multiple pallet platforms distributed axially at intervals. The flipping shaft is located directly opposite the notch and its axial direction is the same as the length direction of the conveyor frame. Each pallet platform is composed of an even number of support rods extending radially symmetrically around the flipping shaft. The surface of the support rod is provided with a soft rubber layer and a shock-absorbing cotton layer located between the soft rubber layer and the support rod. A transfer conveyor belt is located downstream of the flipping mechanism and connects to the conveyor belt assembly of another polishing mechanism. The transfer conveyor belt includes a plurality of conveyor belts spaced apart. The support rod extends into the gap between the conveyor belts to receive the flipped plate and transport it to the waiting area of ​​another polishing mechanism.

[0004] In some embodiments, the pallet platforms are arranged in three groups at equal intervals along the axial direction of the flipping axis, and each group of pallet platforms consists of six support rods spaced at 60-degree intervals.

[0005] In some embodiments, the thickness of the soft rubber layer on the surface of the support rod is 3-5 mm.

[0006] In some embodiments, the shock-absorbing cotton layer is made of closed-cell polyethylene foam material.

[0007] In some embodiments, the spacing between the four conveyor belts of the transfer conveyor is 1.2-1.5 times that of the support rod.

[0008] In some embodiments, the outer sides of the two outermost pallet platforms are provided with baffles for preventing the plates from sliding out.

[0009] In some embodiments, the notch is located on the side of the first polishing mechanism conveyor frame closer to another polishing mechanism, and the roller within the notch has a unilaterally rotatable and fixed structure.

[0010] In some embodiments, the axial direction of the flipping shaft is the same as the length direction of the conveyor frame.

[0011] In some embodiments, the support rod is driven by the flipping motor to complete a 180-degree rotation flipping action to flip the board over.

[0012] The polishing device of this application achieves differentiated polishing of both sides of the board (e.g., one side high-gloss and the other rough) through the coordinated design of a dual polishing mechanism and a flipping mechanism, solving the technical problem that traditional double-sided synchronous polishing cannot meet personalized needs. The flipping mechanism adopts a support rod structure with a soft rubber plate and a shock-absorbing cotton layer, which effectively absorbs the inertial impact of flipping and increases the coefficient of friction, reducing the offset of the board. The entire device significantly lowers the technical implementation threshold while ensuring polishing accuracy.

[0022] Please see Figure 1 and Figure 2This application provides a polishing apparatus 100 for a sheet metal, including a polishing mechanism 10, a flipping mechanism 20, and a transfer conveyor belt 30. Two polishing mechanisms 10 arranged in parallel are used to independently polish opposite sides of the sheet metal. Each polishing mechanism 10 includes a polishing machine body 11 and a conveyor belt assembly 12 disposed at both ends of the polishing machine body 11. The conveyor belt assembly 12 includes a conveyor frame 121, a drive motor 122, and a plurality of bearing rollers 123. The tail end of the conveyor frame 121 is provided with a waiting area 124, wherein the waiting area 124 is provided with a notch 125 on the side adjacent to the conveyor frame 121 of the other polishing mechanism 10. A flipping mechanism 20 is located in the gap between the two polishing mechanisms 10 at their ends. The flipping mechanism 20 includes a base 21, a flipping frame 22 mounted on the base 21, and a flipping motor 23 that drives the flipping frame 22 to rotate. The flipping frame 22 includes a flipping shaft and a plurality of pallet platforms 221 spaced apart along the axial direction. The flipping shaft is located directly opposite the notch 125 and its axial direction is the same as the length direction of the conveyor frame 121. Each pallet platform 221 is composed of an even number of support rods 222 extending radially symmetrically around the flipping shaft. The surface of the support rods 222 is provided with a soft rubber layer and a layer of shock-absorbing cotton 224 located between the soft rubber layer and the support rods 222. A transfer conveyor belt 30 is located downstream of the flipping mechanism 20 and connects to the conveyor belt assembly 12 of the other polishing mechanism 10. The transfer conveyor belt 30 includes a plurality of conveyor belts 31 spaced apart. The support rods 222 extend into the gaps between the conveyor belts 31 to receive the flipped plates and transport them to the waiting area 124 of the other polishing mechanism 10.

[0023] The polishing device 100 of this application, through the coordinated design of the dual polishing mechanism 10 and the flipping mechanism 20, achieves differentiated polishing of both sides of the board (such as one side being high-gloss and the other rough), solving the technical problem that traditional double-sided synchronous polishing cannot meet personalized needs. The flipping mechanism 20 adopts a support rod 222 structure with a soft rubber plate 223 and a shock-absorbing cotton 224 layer, which effectively absorbs the inertial impact of flipping and increases the coefficient of friction, reducing the offset of the board. The entire device significantly reduces the technical implementation threshold while ensuring polishing accuracy.

[0024] For details, please continue reading Figure 1 and Figure 2The polishing equipment consists of a polishing mechanism 10, a flipping mechanism 20, and a transfer conveyor belt 30. Two polishing mechanisms 10 are arranged in parallel, maintaining a certain distance from each other, and are responsible for polishing both sides of the board. The flipping mechanism 20 and the transfer conveyor belt 30 are located at the end between the two polishing mechanisms 10. After one polishing mechanism 10 completes polishing one side of the board, the flipping mechanism 20 flips the board 180 degrees and places it on the transfer conveyor belt 30. The transfer conveyor belt 30 then transports the board to the other polishing mechanism 10, which polishes the other side of the board from its tail end to its front end until completion.

[0025] The polishing mechanism 10 mainly consists of a polishing machine body 11 and conveyor belt assemblies 12 located at both ends of it. The main function of one conveyor belt assembly 12 is to smoothly and efficiently transport the material to be processed to the working area of ​​the polishing machine for fine polishing; while the other conveyor belt assembly 12 is responsible for smoothly removing the material that has completed the polishing process from the polishing area for subsequent processing or storage.

[0026] Each conveyor belt assembly 12 comprises several key components, including a conveyor frame 121 for supporting and securing the entire conveying system, a drive motor 122 mounted on the conveyor frame 121, and multiple rollers for carrying and transporting the sheet metal. A waiting area 124 is provided at the tail end of the conveyor frame 121. Particularly noteworthy is that in the conveyor belt assembly 12 responsible for the initial polishing of the sheet metal, the waiting area 124 of its conveyor frame 121 is designed with a dedicated notch 125, located on the side near the other polishing mechanism 10, to facilitate smooth transition and positioning of the sheet metal. Furthermore, the rollers located within the notch 125 employ a unique design that allows for unilateral rotatable fixing.

[0027] Please combine Figure 3 The tilting mechanism 20 consists of a base 21, a tilting frame 22 mounted on the base 21, and a tilting motor 23. The tilting frame 22 contains a tilting shaft 24, on which multiple pallet platforms 221 are mounted, arranged axially. The tilting shaft 24 is located at the notch 125, and its axis coincides with the center line of the conveyor frame 121. Each pallet platform 221 extends outward from a central bushing and is composed of an even number of supporting rods 222, which are symmetrical about the central axis in the radial direction of the tilting shaft 24, and are arranged in pairs.

[0028] In the embodiments of this application, there are six support rods 222, evenly distributed at 60-degree intervals. Further, three sets of pallet platforms 221 are spaced apart along the axial direction of the flipping shaft 24. In the axial direction of the flipping shaft 24, the three support rods 222 form a support plane, that is, three mutually symmetrical support planes are formed along the circumference of the flipping shaft 24. The support rods 222 extend into the intervals of the rollers in the conveyor frame 121. The rotation of the rollers lifts the plates in the waiting area 124, and the plates are flipped by the flipping shaft 24 to complete the flipping process.

[0029] Further, please refer to Figure 2 and Figure 3 Considering that in actual operation, the board needs to be flipped through the rotation of the flipping frame 22 to achieve its surface flipping process, during this rotation, a certain distance exists between the flipping shaft 24 of the flipping frame 22 and the radially arranged support rod 222. This distance may cause the board to shift in position during the flipping process, affecting the stability and accuracy of the flipping. To effectively solve this problem, a layer of soft rubber sheet 223 and shock-absorbing cotton 224 sandwiched between the soft rubber sheet 223 and the support rod 222 are arranged on the surface where the support rod 222 contacts the board after flipping.

[0030] The outer surface of the soft rubber sheet 223 is specially designed to have a high coefficient of friction. The thickness of the soft rubber layer is 3-5mm, and its surface coefficient of friction is not less than 0.812, which significantly enhances its gripping performance and ensures that the sheet can be stably supported during the flipping process, reducing slippage.

[0031] The 224-layer shock-absorbing cotton is made of closed-cell polyethylene foam material with a density of 30-45 kg / m³. The 224-layer shock-absorbing cotton can effectively absorb and buffer the inertial force impact generated when the board is flipped, thereby preventing unnecessary displacement of the board during the flipping process and ensuring the stability and safety of the entire flipping process.

[0032] Furthermore, please refer to Figure 2 Considering that in actual use scenarios, the plate may slide off the pallet platform 221 due to various external forces or unstable conditions, baffles 225 are provided on the sides of the pallet platform 221 at both ends to prevent such situations from occurring. These baffles 225 are used to block the plate 225 and ensure that it is placed securely on the pallet platform 221.

[0033] The transfer conveyor belt 30 is used to receive the sheet metal after it has been flipped by the flipping mechanism 20 and transport it to the waiting area 124 of another conveyor belt. The transfer conveyor belt 30 includes multiple conveyor belts 31 arranged in a spaced array, specifically four belts. Support rods 222 also extend into the spaces between the conveyor belts 31.

[0034] The transfer conveyor belt 30 plays a crucial role in the entire production process. Its main function is to receive the boards after they have been flipped by the flipping mechanism 20. After the flipping mechanism 20 completes the flipping operation, the boards are accurately placed on the transfer conveyor belt 30, which then smoothly transports these boards to the waiting area 124 of another conveyor belt.

[0035] Please see Figure 1 The transfer conveyor belt 30 adopts a special structural design, including multiple conveyor belts 31 arranged in an interval array. Specifically, there are four conveyor belts 31. This design, with multiple conveyor belts 31 arranged at intervals, ensures sufficient and uniform support for the sheet material, preventing it from tilting or slipping during transportation. It also facilitates the coordination with other components. Specifically, the support rod 222 extends into the intervals of the conveyor belts 31.

[0036] The working process of the polishing equipment is as follows:

[0037] 1. First, the sheet material is introduced into the first polishing unit 10 to complete the polishing operation on one side. Then, the conveyor belt transports the sheet material to the waiting area 124.

[0038] 2. The flipping motor 23 then starts, driving the pallet platform 221 to rotate 180 degrees. The support rod 222 of the flipping mechanism 20 lifts the plate by extending from bottom to top into the gap of the roller. The soft rubber plate 223 and the shock-absorbing cotton 224 work together to ensure the stability of the flipping process.

[0039] 3. After the flipping is completed, the board will fall onto the transfer conveyor belt 30, and then the board will be transported to the waiting area 124 of the second polishing mechanism 10.

[0040] 4. The second polishing mechanism 10 transports the board back to complete the polishing operation on the other side. Finally, the conveyor belt outputs the finished polished board.
