Description

Technical Field

[0001] This invention relates to the field of board grinding technology, specifically a grinding device for processing engineered wood panels. Background Technology

[0002] With the rapid development of industries such as construction and furniture manufacturing, the demand for engineered wood products is increasing, and the requirements for their quality and surface processing precision are also becoming higher. High-quality engineered wood products need to have a smooth and flat surface to meet the requirements of subsequent processes such as lamination and painting. Therefore, efficient and precise sanding equipment has become an indispensable piece of equipment in the process of engineered wood product processing. When processing engineered wood panels, sanding is required. Generally, existing sanding devices place the panels on a conveyor belt and use a sanding disc to slide back and forth on the top of the panel to achieve the sanding purpose. Because the top of the panel is sanded by the sliding sanding disc, burrs are easily generated at the corners of the panel and the sidewalls of the panel are difficult to sand. This can easily lead to dead corners during sanding and affect the subsequent sanding effect and quality. Summary of the Invention

[0003] The purpose of this invention is to provide a sanding device for processing engineered wood panels, so as to solve the problems mentioned in the background art.

The top of the sliding plate 1 is rotatably connected to one of the long plates. A motor 1 is fixedly connected to the top of the sliding plate 1.

Two round openings are opened on the top of the sliding plate 1. The cleaning mechanism includes a sliding plate two that is slidably connected to the outer surface of another set of limiting blocks. A motor two is fixedly connected to the top of the sliding plate two. The top of the sliding plate two is rotatably connected to the side wall of another long plate. Three cleaning rollers are rotatably connected to the bottom outer wall of the sliding plate two. A belt is sleeved and connected to the output end of the motor two. The three cleaning rollers are driven by the belt to the output end of the motor two.

[0011] Furthermore, the oscillating assembly includes an inclined rod disposed on the outer surface of the polishing wheel, with spring rods fixedly connected to both the front and back sides of the inclined rod, and a fixed shaft fixedly connected to the top of the inclined rod, the top of which is fixedly connected to the bottom outer wall of the reinforcing plate. The fixing component includes a push rod rotatably connected to the outer surface of the spring rod, a sliding rod rotatably connected to the end of the push rod away from the tilting rod, a square plate slidably connected to the outer surface of the sliding rod, the top of the square plate being fixedly connected to the bottom outer wall of the sliding plate, and two short rods fixedly connected to the left and right sides of the sliding rod.

[0012] Furthermore, the pushing component includes a C-shaped sliding block slidably connected to the outer surface of the sliding rod. The left and right inner walls of the C-shaped sliding block are provided with guide grooves. One end of the short rod away from the sliding rod is slidably connected to the inside of the guide groove. The inner wall of the C-shaped sliding block is inclined. One of the short rods contacts the inclined part of the inner wall of the C-shaped sliding block, and an elastic sand disc is fixedly connected to the bottom of the C-shaped sliding block; Among them, the outer surface of the C-shaped sliding block is slidably connected to a limit frame, the top of the limit frame is fixedly connected to the bottom of the first sliding plate, the outer surface of the elastic sand disc is fixedly connected to two short shafts, the top of the elastic sand disc is fixedly connected to a tension spring, and the top of the tension spring is fixedly connected to the bottom inner wall of the first sliding plate.

[0013] Furthermore, the auxiliary component includes a sliding frame slidably connected to the outer surfaces of the two short shafts.

[0014] Furthermore, the stabilizing component includes an auxiliary rod rotatably connected to the end of the L-axis away from the return spring, a semi-circular plate rotatably connected to the end of the auxiliary rod away from the L-axis, a number of ball bearings rotatably connected to the side wall of the semi-circular plate, a limit plate rotatably connected to the end of the semi-circular plate away from the auxiliary rod, and a fixed connection between the end of the limit plate away from the semi-circular plate and the inner wall of the fixed frame.

[0015] The present invention has the following beneficial effects: 1. In this invention, the rotation of the transmission assembly drives the sliding plate to slide back and forth. When the sliding plate slides backward, the front push rod slides inside the C-shaped sliding block through the sliding rod, causing the elastic sanding disc to deflect towards the board and contact the side wall of the board. When the elastic sanding disc contacts the side wall of the board, it will rub and clean the burrs formed on the side wall and the edge of the side wall of the board during the board conveying. The friction cleaning between the elastic sanding disc and the side wall and edge of the board can reduce the occurrence of burrs on the edge of the board when it is polished by the rotation of the polishing wheel, or the side wall of the board is difficult to polish due to the rotation of the polishing wheel. This reduces the number of polishing dead corners and improves the subsequent polishing efficiency and polishing effect.

[0016] 2. In this invention, when the elastic sanding disc slides downwards, it can make close contact with the top of the board when the other elastic sanding disc rotates and contacts the side wall of the board. Subsequently, when the sliding plate slides back and forth, the downward sliding of the elastic sanding disc and its contact with the board can reduce the situation where the top of the board is difficult to polish due to the deflection of the elastic sanding disc, which would otherwise occur when the sliding plate drives the polishing wheel to slide. Through the close contact between the elastic sanding disc and the side wall of the board, when the sliding plate slides against the side wall of the board and one of the elastic sanding discs deflects, the close contact between the elastic sanding disc and the side wall of the board can further increase the sliding friction on the surface of the board during sliding, reducing the situation where one of the elastic sanding discs is difficult to polish during deflection, thereby further enhancing the polishing efficiency of the board.

[0017] 3. In this invention, when one of the elastic sanding discs deflects and the other elastic sanding disc slides downward, the downward sliding of the elastic sanding disc will cause the sliding frame to slide downward, and push the L-axis to slide through the middle plate. The semi-circular plate will rotate when the L-axis slides and rotate in the direction of the deflecting elastic sanding disc. When the semi-circular plate rotates, it will fit against the side wall of the plate and provide lateral support. The lateral support of the semi-circular plate can reduce the displacement or deviation of the plate on the conveyor belt caused by the deflection of the elastic sanding disc when the other elastic sanding disc rotates and contacts the side wall of the plate. This can further ensure the accuracy of the plate's position during grinding, reduce the impact of the plate's deflection on the grinding area and grinding surface of the subsequent plate, and improve the subsequent grinding quality while ensuring the stability of the plate's position.

[0028] The conveying assembly 11 includes a conveyor belt 111 rotatably connected to the top of the main body 1. Several limiting blocks 114 are fixedly connected to the bottom inner wall of the fixed frame 101. The limiting blocks 114 are arranged in pairs and symmetrically distributed around the reinforcing plate 112. The two sets of limiting blocks 114 are distributed at equal distances.

[0029] The transmission assembly 21 includes a sliding plate 211 slidably connected to the outer surface of a set of limiting blocks 114. The top of the sliding plate 211 is rotatably connected to one of the long plates. A motor 212 is fixedly connected to the top of the sliding plate 211. The output end of the motor 212 passes through the bottom outer wall of the sliding plate 211 and extends to the outside. A polishing wheel 213 is fixedly connected to the extension end of the motor 212. Two round openings are opened on the top of the sliding plate 211. The cleaning mechanism 22 includes a sliding plate 221 slidably connected to the outer surface of another set of limiting blocks 114. A motor 222 is fixedly connected to the top of the sliding plate 221. The top of the sliding plate 221 is rotatably connected to the side wall of another long plate. Three cleaning rollers 223 are rotatably connected to the bottom outer wall of the sliding plate 221. A belt is sleeved and connected to the output end of the motor 222. The three cleaning rollers 223 are driven to the output end of the motor 222 through the belt. The rotation of the transmission assembly 201 can drive the sliding plate 221 to slide back and forth. When the sliding plate 221 slides backward, the push rod 321 on the front slides inside the C-shaped sliding block 323 through the sliding rod 322.

[0030] The swing assembly 31 includes an inclined rod 312 disposed on the outer surface of the polishing wheel 213. Spring rods 311 are fixedly connected to both the front and back of the inclined rod 312. A fixed shaft 313 is fixedly connected to the top of the inclined rod 312. The top of the fixed shaft 313 is fixedly connected to the bottom outer wall of the reinforcing plate 112. The fixing component includes a push rod 321 rotatably connected to the outer surface of the spring rod 311. A sliding rod 322 is rotatably connected to the end of the push rod 321 away from the tilting rod 312. A square plate is slidably connected to the outer surface of the sliding rod 322. The top of the square plate is fixedly connected to the bottom outer wall of the sliding plate 211. Two short rods are fixedly connected to the left and right sides of the sliding rod 322. When the sliding rod 322 slides, it pushes the inner wall of the guide groove 325 through the short rods, causing the elastic sanding disc 324 to deflect towards the plate. When the elastic sanding disc 324 deflects, it contacts the side wall of the plate. When the elastic sanding disc 324 contacts the side wall of the plate, it will rub and clean the burrs formed on the side wall and the edge of the side wall of the plate during the plate conveying.

[0031] The pushing component 32 includes a C-shaped sliding block 323 slidably connected to the outer surface of the sliding rod 322. The left and right inner walls of the C-shaped sliding block 323 are provided with guide grooves 325. One end of a short rod away from the sliding rod 322 is slidably connected to the inside of the guide groove 325. The inner wall of the C-shaped sliding block 323 is inclined. One of the short rods contacts the inclined part of the inner wall of the C-shaped sliding block 323, and the bottom of the C-shaped sliding block 323 is fixedly connected to an elastic sand disc 324. Among them, the outer surface of the C-shaped sliding block 323 is slidably connected to the limiting frame 326, the top of the limiting frame 326 is fixedly connected to the bottom of the sliding plate 211, the outer surface of the elastic sanding disc 324 is fixedly connected to two short shafts, the top of the elastic sanding disc 324 is fixedly connected to a tension spring, and the top of the tension spring is fixedly connected to the bottom inner wall of the sliding plate 211. When the elastic sanding disc 324 slides downward, it can make close contact with the top of the plate when the other elastic sanding disc 324 rotates and contacts the side wall of the plate. Then, when the sliding plate 211 slides back and forth, the contact between the elastic sanding disc 324 and the plate can reduce the situation where the top of the plate is difficult to polish due to the deflection of the elastic sanding disc 324 when the sliding plate 211 drives the polishing wheel 213 to slide.

[0032] The auxiliary component 33 includes a sliding frame 331 slidably connected to the outer surfaces of two short shafts. A middle plate 332 is rotatably connected to the side of the sliding frame 331 near the fixed shaft 313. An L-axis 333 is rotatably connected to the side wall of the middle plate 332. The end of the L-axis 333 near the sliding groove 113 slides inside the sliding groove 113. A return spring is fixedly connected to the side wall of the L-axis 333 inside the sliding groove 113. The end of the return spring away from the L-axis 333 is fixedly connected to the inner wall of the sliding groove 113. When one of the elastic sanding discs 324 deflects and the other elastic sanding disc 324 slides downward, the downward sliding of the elastic sanding disc 324 will drive the sliding frame 331 to slide downward, and push the L-axis 333 to slide through the middle plate 332.

[0033] The stabilizing component 34 includes an auxiliary rod 341 rotatably connected to the end of the L-axis 333 away from the return spring. A semicircular plate 342 is rotatably connected to the end of the auxiliary rod 341 away from the L-axis 333. Several ball bearings are rotatably connected to the side wall of the semicircular plate 342. A limiting plate 343 is rotatably connected to the end of the semicircular plate 342 away from the auxiliary rod 341. The end of the limiting plate 343 away from the semicircular plate 342 is fixedly connected to the inner wall of the fixed frame 101. The semicircular plate 342 will rotate and rotate in the direction of deflecting the elastic sanding disc 324 when sliding on the L-axis 333. When rotating, the semicircular plate 342 will adhere to the side wall of the plate and provide lateral support. The lateral support of the semicircular plate 342 can reduce the deflection of the elastic sanding disc 324 when it rotates and comes into contact with the side wall of the plate.

[0034] In use, first start the conveyor belt 111 inside the main body 1, then simultaneously start motor 212, transmission assembly 201 and motor 222. Then connect the exhaust pipe to the round opening at the top of sliding plate 211. Then place the plate on the surface of the conveyor belt 111. When the conveyor belt 111 is working, it will drive the plate to be conveyed. When the plate is conveyed to the bottom of sliding plate 221, the operation of motor 212 will drive polishing wheel 213 to grind and polish the top of the plate. At the same time, when the transmission assembly 201 is working, it will drive sliding plate 211 through the long plate to make polishing wheel 213 slide back and forth on the surface of the plate to grind. Then the grinding waste will be drawn out through the round opening. After that, when the plate slides to the bottom of sliding plate 221, it will be cleaned and conveyed out by the rotation of cleaning roller 223, completing the grinding effect.

[0035] When the transmission assembly 201 rotates, it drives the sliding plate 211 to slide back and forth via the long plate. When the sliding plate 211 slides backward, the front push rod 321 slides inside the C-shaped sliding block 323 via the sliding rod 322. When the sliding rod 322 slides, it pushes the inner wall of the guide groove 325 through the short rod, causing the C-shaped sliding block 323 to drive the elastic sanding disc 324 to deflect towards the plate. When the elastic sanding disc 324 deflects, it will make contact with the side wall of the plate. When the elastic sanding disc 324 comes into contact with the side wall of the board, it will rub and clean the burrs formed on the side wall and the edge of the side wall of the board during the board conveying. The friction cleaning between the elastic sanding disc 324 and the side wall and edge of the board can reduce the occurrence of burrs on the edge of the board when it is subjected to the rotation of the polishing wheel 213, or the side wall of the board is difficult to be polished by the rotation of the polishing wheel 213, which will make the side wall difficult to polish. It can reduce the dead corners of polishing and improve the subsequent polishing efficiency and polishing effect.

[0036] When one of the push rods 321 pushes the C-shaped sliding block 323 to rotate within the guide groove 325 via the sliding rod 322 and the short rod on the sliding rod 322, the other sliding rod 322 will slide under the pull of the push rod 321. When the other sliding rod 322 slides, it will press the inclined part inside the C-shaped sliding block 323 through the short rod, thereby causing the C-shaped sliding block 323 to drive the elastic sanding disc 324 to slide downward. When the elastic sanding disc 324 slides downward, it can make close contact with the top of the plate when the other elastic sanding disc 324 rotates and contacts the side wall of the plate. Subsequently, when the sliding plate 211 slides back and forth, the elastic sanding disc 324 slides downward. Contact with the board can reduce the situation where the top of the board is difficult to polish due to the deflection of the elastic sanding disc 324 when the sliding plate 211 drives the polishing wheel 213 to slide. By making close contact with the side wall of the board as the sliding plate 211 slides on the side wall of the board and one of the elastic sanding discs 324 deflects, the elastic sanding disc 324 can further increase the sliding friction on the surface of the board when it slides, reducing the situation where one of the elastic sanding discs 324 is difficult to polish when it deflects, thereby further enhancing the polishing efficiency of the board.

[0037] When one of the elastic sanding discs 324 deflects and the other elastic sanding disc 324 slides downward, the downward sliding of the elastic sanding disc 324 will cause the sliding frame 331 to slide downward. When the sliding frame 331 slides downward, it will push the L-axis 333 to slide through the intermediate plate 332. When the L-axis 333 slides downward, it will push the semi-circular plate 342 to rotate through the auxiliary rod 341. When the semi-circular plate 342 rotates, it will rotate in the direction of the deflecting elastic sanding disc 324. When the semi-circular plate 342 rotates, it will fit against the side wall of the plate and provide lateral support. Through the lateral support of the semi-circular plate 342, To reduce the possibility of displacement or deviation of the plate on the conveyor belt 111 caused by the deflection of the elastic sanding disc 324 during rotation and contact with the side wall of the plate, the support of the side wall of the plate by the semi-circular plate 342 ensures that the plate can be stably conveyed on the conveyor belt 111 after sliding and being pushed by the rotation of the elastic sanding disc 324 on the other side. This further ensures the accuracy of the plate's position during grinding, reduces the impact of plate deflection on the grinding area and surface area of ​​the subsequent plate, and improves the subsequent grinding quality while ensuring the stability of the plate's position.
