Description

Technical Field

[0001] This invention belongs to the field of flooring production technology, and more specifically, relates to an automatic edge grinding device and its usage method for flooring processing. Background Technology

[0002] Wood flooring refers to flooring made of wood. In my country, wood flooring is mainly divided into six categories: solid wood flooring, engineered wood flooring, multi-layer composite flooring, bamboo flooring, and cork flooring, as well as the emerging wood-plastic composite flooring. During the wood processing, the wood often needs to be cut. After cutting, burrs easily form on the edges of the cut surfaces, which requires edge grinding devices to smooth them out.

[0003] In existing technologies, handheld edge grinding devices are commonly used to grind the edges of wood flooring. This often requires manual edge changing and moving of the wood flooring to grind the remaining sides. Furthermore, handheld devices are difficult to control the force applied to, and require highly skilled workers with many years of experience to complete the task effectively. As a result, the edge grinding speed is slow, the manual workload is heavy, the production efficiency is very low, and the product quality is inconsistent, which can easily lead to defective products and cause considerable losses to enterprises. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides an automatic edge grinding device and a method for using floor processing, so as to solve the related technical problems mentioned in the background art.

[0005] This invention is implemented as follows:

[0006] An automatic edge-grinding device for flooring processing includes a conveying device. The conveying device includes a support frame. An automatic conveyor belt and two flow bars are fixedly installed on the top of the support frame along the conveying direction. The two flow bars are located on the left and right sides of the top of the support frame and are spaced apart in the middle. A short-side grinding mechanism is provided on the top of the automatic conveyor belt near the output end. A long-side grinding mechanism is provided between the two flow bars near the output end. A pushing mechanism is provided below the gap between the two flow bars. A feeding trough is provided on the top of the automatic conveyor belt near the input end. Processed flooring is stacked in the feeding trough. The output ends of the two flow bars are fixedly installed with a discharge slide plate. The automatic conveyor belt conveys a single piece of processed flooring, which is then ground sequentially by the short-side grinding mechanism and the long-side grinding mechanism, and slides into a transfer trolley via the discharge slide plate.

[0007] Furthermore, the short-side grinding mechanism includes a fixed bracket, which is fixedly installed on the top of the automatic conveyor belt. A guide groove is formed in the center of the top of the fixed bracket. A drive rack is fixedly connected to the top of the fixed bracket near the back of the guide groove. A rotating gear meshes with the front of the drive rack. The rotating gear is fixedly connected to the surface of the short-side grinding rod. The top of the short-side grinding rod is fixedly installed to the output shaft of a bidirectional motor. The bidirectional motor is fixedly installed at the bottom of a sliding bracket. The sliding bracket is fixedly installed on the top of the fixed bracket via a slide rail assembly. The grinding rod is slidably connected to the guide groove. A grinding head is provided at the bottom of the short side grinding rod. The position of the grinding head matches the short side of the processed floor. Guide rods are slidably connected vertically to the front and back of the fixed bracket, near the left and right sides respectively. The bottom of the two guide rods on the front or back is fixedly connected to the top of the clamping block. An electric hydraulic cylinder is fixedly installed in the middle of the front and back of the top of the fixed bracket. The bottom end of the telescopic shaft of the electric hydraulic cylinder is fixedly connected to the center of the top of the clamping block. The bottom of the clamping block presses against the ground of the processed floor.

[0008] Furthermore, a stepped through hole is provided at the top center of the clamping block, and the bottom end of the telescopic shaft of the electric hydraulic cylinder is movably connected to the inside of the stepped through hole. A buffer spring is sleeved on the outside of the guide rod, and the two ends of the buffer spring abut against the bottom of the top plate of the fixed bracket and the top of the clamping block, respectively.

[0009] Furthermore, the long-side grinding mechanism includes a mounting bracket, which is fixedly connected between the two flow strips. A left grinding rod and a right grinding rod are respectively bearing connected to the left and right sides of the mounting bracket. The top of the left grinding rod passes through the top of the mounting bracket and is fixedly connected to the output shaft of the active motor. The active motor is fixedly mounted on the top of the mounting bracket via a motor frame. An active gear is fixedly connected to the surface of the left grinding rod near the top of the mounting bracket. A transmission gear meshes with the right side of the active gear. The transmission gear is rotatably connected to the top of the mounting bracket via a shaft. A driven gear is fixedly connected to the top of the right grinding rod. The transmission gear and the driven gear are connected by a transmission chain. The distance between the left and right grinding rods matches the width of the processed floor.

[0010] Furthermore, the pushing mechanism includes two synchronous pulleys. The pushing mechanism is fixedly installed near the center of the rotating shaft. The rotating shaft is fixedly installed in the center of the support frame via bearings. One end of any one of the rotating shafts is fixedly installed to the output shaft of the pushing motor. The pushing motor is fixedly installed to the support frame via a frame body. The two synchronous pulleys are arranged sequentially along the transmission direction, and their distance is greater than the distance between the long-side grinding mechanism and the short-side grinding mechanism. The two synchronous pulleys are connected by a synchronous belt drive. Multiple support feet are fixedly installed at equal intervals on the left side of the support frame, between the two synchronous pulleys. The left and right sides of the top of the multiple support feet are fixedly connected to two sets of slide rail assemblies, respectively. The sliders of the two sets of slide rail assemblies are fixedly installed on the left and right sides of the bottom of the folding push rod. The folding push rod clamps and fixes a section of the synchronous belt at its bottom.

[0011] Furthermore, the folding push rod includes a base plate, the right end of the top of the base plate is hinged to the left side of the bottom of the push rod, the left end of the base plate is hinged to the bottom of the cylinder seat of the electric telescopic rod, the top end of the telescopic shaft of the electric telescopic rod is hinged to the front of the push rod near the middle, a clamping plate is fastened to the middle of the bottom surface of the base plate by bolts, a section of the synchronous belt is clamped between the base plate and the clamping plate, and the two sliders are respectively fixedly installed on the left and right sides of the bottom of the base plate.

[0012] Furthermore, a pressure roller is fixedly installed between the two flow strips and near the back of the long-side grinding mechanism. The top surface of the processing floor is in close contact with the bottom of the pressure roller. A set of guide plates is provided on the top of the conveying device and near the back of the long-side grinding mechanism and the short-side grinding mechanism, respectively. Each set of guide plates consists of two symmetrically arranged guide plates. A dustproof cover is provided on the top of the conveying device, covering the entire area except for the feeding trough. A recycling box is fixedly installed at the bottom of the support frame, corresponding to the long-side grinding mechanism and the short-side grinding mechanism.

[0013] On the other hand, a method of using an automatic edge-grinding device for floor processing includes the following steps:

[0014] S1. Processing flooring materials

[0015] First, the neatly stacked processing floorboards are placed into the feeding trough by manual feeding. Then, the processing floorboards are conveyed out one by one from the slot at the bottom of the feeding trough by an automatic conveyor belt. When the number of processing floorboards decreases, manual feeding is then carried out again, and this cycle is repeated.

[0016] S2, Short edge polishing.

[0017] A single processing board is conveyed by an automatic conveyor belt to the short-side sanding mechanism. After its front end is detected by an infrared beam sensor, the clamping block is driven down by an electric hydraulic cylinder to press the processing board. The short-side sanding rod is driven to rotate by a bidirectional motor, which in turn drives the rotating gear to reciprocate on the tooth surface of the drive rack. This causes the sliding bracket and the short-side sanding rod to rotate and reciprocate to sand the front end of the current processing board and the tail end of the previous processing board.

[0018] S3, Long edge polishing.

[0019] After the end of the processed floorboard is sanded, the short-side sanding rod of the short-side sanding mechanism returns to its original position and tilts to one side. At this time, the electric telescopic rod of the folding push rod drives the push rod to stand up in a folded state and is exactly at the bottom of the processed floorboard. The push motor of the push mechanism drives the synchronous wheel to drive the synchronous belt to move, thereby driving the folding push rod to push the processed wood board on the surface of the two sets of flow strips into the long-side sanding mechanism. When the front end of the processed floorboard is close to the long-side sanding mechanism, it is first guided by the two stacked guide plates and the bottom of the pressure roller. Then, the left and right sanding rods on both sides of the path sand the two long sides of the processed floorboard. The debris generated during the sanding process will fall into the recycling box for centralized recycling.

[0020] S4. Processing complete, material discharged.

[0021] After the long edge is sanded, the processed floorboard continues to be pushed forward by the pushing mechanism until it tilts due to its own weight and enters the discharge slide plate. After passing through the discharge slide plate, it slides into the transfer trolley and is then manually transferred, thus completing a full one-time automatic edge sanding process for the floorboard.

[0022] The beneficial effects of this invention are:

[0023] (1) The present invention is fully automated and is equipped with an infrared beam switch to detect incoming materials, thereby enabling the device to accurately process and polish the floor. This solves a series of problems caused by the low efficiency, inconsistent quality, high learning threshold for workers, and high scrap rate of hand-held polishing machines, effectively saving enterprise costs and improving enterprise production efficiency.

[0024] (2) This invention automatically sands the long and short sides of the floor in steps by setting up a short side sanding mechanism and a long side sanding mechanism, thereby effectively improving production efficiency. At the same time, by setting up a pushing mechanism in conjunction with a folding push rod, it effectively solves the problem that the long side sanding of the floor requires a pushing force, while the existing automatic conveyor belts cannot meet the requirements by transmitting through friction. This effectively provides a reasonable and uniform pushing force for the floor, which is beneficial to the quality of the long side sanding of the floor, thereby effectively improving the quality of the produced products.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] Example

[0041] Specifically, such as Figure 1-8As shown, an automatic edge grinding device for floor processing is provided, including a conveying device 1. The conveying device 1 includes a support frame 17. An automatic conveyor belt 12 and two flow bars 14 are fixedly installed on the top of the support frame 17 along the conveying direction. The two flow bars 14 are located on the left and right sides of the top of the support frame 17 and are spaced apart in the middle. A short-side grinding mechanism 5 is provided on the top of the automatic conveyor belt 12 near the output end. A long-side grinding mechanism 3 is provided between the two flow bars 14 near the output end. A pushing mechanism 4 is provided below the gap between the two flow bars 14. A feeding trough 2 is provided on the top of the automatic conveyor belt 12 near the input end. Processed floorboards 7 are stacked in the feeding trough 2. The output ends of the two flow bars 14 are fixedly installed with a discharge slide plate 16. The automatic conveyor belt 12 conveys a single processed floorboard 7 to pass through the short-side grinding mechanism 5 and the long-side grinding mechanism 3 in sequence for grinding, and then slides into a transfer trolley through the discharge slide plate 16.

[0042] Specifically, such as Figure 1-2 As shown, to solve various problems associated with manual sanding of floorboards 7 using handheld sanders, this device utilizes an automatic conveyor belt 12 mounted on top of the support frame 17, along with a feeding trough 2. This allows for manual feeding of stacked floorboards 7 one by one. The feeding trough 2 is fixedly mounted on top of the automatic conveyor belt 12 and is designed as a C-shape with an open back and a slot at the bottom of its front. The height of this slot is controlled to be greater than the thickness of the floorboard 7 but less than twice its thickness, thus preventing burrs from being passed through the feeding trough 2. The device can output one floorboard, and simultaneously sands the two short sides and two long sides of the processed floorboard 7 by setting short-side sanding mechanism 5 and long-side sanding mechanism 3 in sequence along the conveyor route. This realizes the function of manual feeding and automatic sanding of the processed floorboard 7. The device is fully automated and uses an infrared photoelectric switch to detect the incoming material, which enables the device to accurately process and sand the floorboard. This solves a series of problems caused by manual sanding with handheld sanders, such as low efficiency, inconsistent quality, high learning curve for workers, and high scrap rate due to inconsistent product quality. It effectively saves enterprise costs and improves enterprise production efficiency.

[0043] The short-side grinding mechanism 5 includes a fixed bracket 54, which is fixedly installed on the top of the automatic conveyor belt 12. A guide groove 541 is provided in the center of the top of the fixed bracket 54. A drive rack 55 is fixedly connected to the top of the fixed bracket 54 and near the back of the guide groove 541. A rotating gear 53 meshes with the front of the drive rack 55. The rotating gear 53 is fixedly connected to the surface of the short-side grinding rod 57. The top of the short-side grinding rod 57 is fixedly installed to the output shaft of a bidirectional motor 51. The bidirectional motor 51 is fixedly installed at the bottom of a sliding bracket 52. The sliding bracket 52 is fixedly installed on the top of the fixed bracket 54 via a slide rail assembly 510. The short-side grinding rod 57 is slidably connected to the guide groove 541. A grinding head is provided at the bottom of the short-side grinding rod 57. The position of the grinding head matches the short side of the processing floor 7. Guide rods 56 are slidably connected in the vertical direction on the front and back of the fixed bracket 54, respectively near the left and right sides. The bottom of the two guide rods 56 on the front or back is fixedly connected to the top of the clamping block 59. An electric hydraulic cylinder 58 is fixedly installed in the middle of the front and back of the top of the fixed bracket 54. The bottom end of the telescopic shaft of the electric hydraulic cylinder 58 is fixedly connected to the center of the top of the clamping block 59. The bottom of the clamping block 59 presses against the top surface of the processing floor 7.

[0044] A stepped through hole 591 is provided at the center of the top of the clamping block 59. The bottom end of the telescopic shaft of the electric hydraulic cylinder 58 is movably connected to the inside of the stepped through hole 591. A buffer spring is sleeved on the outside of the guide rod 56. The two ends of the buffer spring abut against the bottom of the top plate of the fixed bracket 54 and the top of the clamping block 59, respectively.

[0045] Specifically, such as Figure 3-4 As shown, the bidirectional motor 51 drives the short-side grinding rod 57 and the rotating gear 53 to rotate synchronously, and the rotating gear 53 crawls on one side of the drive rack 55. Since the sliding bracket 52 of the bidirectional motor 51 is installed on the top of the slide rail assembly 510, the sliding bracket 52 moves in a straight line reciprocating motion as the rotating gear 53 crawls, thereby realizing that the grinding head at the bottom of the short-side grinding rod 57 rotates and reciprocates to grind the burrs on the short side of the floor 7.

[0046] Since the automatic conveyor belt 12 continuously conveys the processed floorboards 7, the infrared photoelectric switch set at the short-side sanding mechanism 5 monitors the process, allowing the sanding head to simultaneously sand the tail end of the previous floorboard and the front end of the current board, thus achieving the function of cyclically sanding the short side of the wood board.

[0047] Meanwhile, to prevent the floor from shifting during the sanding process, an electric hydraulic cylinder 58 is vertically installed at the top of the fixed bracket 54. The extension and retraction of the electric hydraulic cylinder 58 drives the clamping block 59 to descend and clamp the end of the floor for fixation. In order to prevent the floor from being deformed due to excessive force during the clamping process, a stepped through hole 591 is opened in the middle of the clamping block 59, and the end of the electric hydraulic cylinder 58 is movably connected to it. Since the clamping block 59 has a certain amount of movement in the vertical direction, when the pressure is too high, the clamping block 59 can squeeze the buffer spring upward to offset part of the pressure, thereby preventing damage to the floor. By setting up a short-side sanding mechanism 5, two sets of short-side sanding rods 57 are driven by a bidirectional motor 51 to sand the short side of the floor back and forth. The force and speed are consistent, so that the quality of the sanded floor can be kept consistent and the scrap rate is greatly reduced.

[0048] The long-side grinding mechanism 3 includes a mounting bracket 32, which is fixedly connected between two flow bars 14. A left grinding rod 35 and a right grinding rod 37 are respectively connected to the left and right sides of the mounting bracket 32 ​​by bearings. The top of the left grinding rod 35 passes through the top of the mounting bracket 32 ​​and is fixedly connected to the output shaft of the drive motor 31. The drive motor 31 is fixedly mounted on the top of the mounting bracket 32 ​​by a motor frame. A drive gear 33 is fixedly connected to the surface of the left grinding rod 35 near the top of the mounting bracket 32. A transmission gear 34 meshes with the right side of the drive gear 33. The transmission gear 34 is rotatably connected to the top of the mounting bracket 32 ​​by a shaft. A driven gear 38 is fixedly connected to the top of the right grinding rod 37. The transmission gear 34 and the driven gear 38 are connected by a transmission chain 36. The distance between the left grinding rod 35 and the right grinding rod 37 matches the width of the processing floor 7.

[0049] Specifically, such as Figure 5 As shown, the long-side sanding mechanism 3 drives the left sanding rod 35 and the drive gear 33 fixed on it to rotate synchronously via the active motor 31, thereby driving the transmission gear 34, transmission chain 36 and driven gear 38 to follow. The driven gear 38 drives the right sanding rod 37 to rotate in the opposite direction to the left sanding rod 35. The two sanding heads at the bottom of the right sanding rod 37 and the left sanding rod 35 rotate in opposite directions to sand the long side of the floor along the path. At the same time, to prevent the floor from shifting or jumping, a pressure roller 15 is set near the input end of the long-side sanding mechanism 3. By passing the floor through its bottom and cooperating with the guide plates 13 set on both sides, the floor can be sanded stably. With the above settings, the floor can be rolled forward between the two sanding heads, resulting in good sanding effect, balanced force transmission and high sanding precision.

[0050] The pushing mechanism 4 includes two synchronous pulleys 43. The pushing mechanism 4 is fixedly installed near the middle of the rotating shaft 42. The rotating shaft 42 is fixedly installed in the middle of the support frame 17 through bearings. One end of any rotating shaft 42 is fixedly installed to the output shaft of the pushing motor 41. The pushing motor 41 is fixedly installed to the support frame 17 through the frame body. The two synchronous pulleys 43 are arranged sequentially along the transmission direction, and their distance is greater than the distance between the long side grinding mechanism 3 and the short side grinding mechanism 5. The two synchronous pulleys 43 are connected by a synchronous belt 44. Multiple support feet 45 are fixedly installed at equal intervals on the middle of the left side of the support frame 17 between the two synchronous pulleys 43. The left and right sides of the top of the multiple support feet 45 are fixedly connected to two sets of slide rail assemblies 510 respectively. The sliders of the two sets of slide rail assemblies 510 are fixedly installed on the left and right sides of the bottom of the folding push rod 8. The folding push rod 8 clamps and fixes a section of the synchronous belt 44 at its bottom.

[0051] The folding push rod 8 includes a base plate 83. The top right end of the base plate 83 is hinged to the bottom left side of the push rod 81. The left end of the base plate 83 is hinged to the bottom of the cylinder seat of the electric telescopic rod 82. The top end of the telescopic shaft of the electric telescopic rod 82 is hinged to the front of the push rod 81 and near the middle. A clamping plate 84 is fastened to the middle of the bottom surface of the base plate 83 by bolts. A section of the synchronous belt 44 is clamped between the base plate 83 and the clamping plate 84. Two sliders are fixedly installed on the left and right sides of the bottom of the base plate 83, respectively.

[0052] Specifically, such as Figure 6-7 As shown, after the short side of the base plate 83 is sanded, it will enter the top of the flow strip 14 without power output. Therefore, it is necessary to continue to provide forward power to the floor to sand its long side. By setting a pushing mechanism 4 in the gap between the flow strips 14 on the left and right sides, the floor is pushed forward at a constant speed from the tail end by the pushing mechanism 4, so that it has enough power to enter the long side sanding mechanism 3 for long side sanding. In this case, by matching the distance between the short side sanding mechanism 5 and the long side sanding mechanism 3, two synchronous wheels 43 are set in sequence and connected by a synchronous belt 44. Then, by fixing the rotating shaft 42 of any synchronous wheel 43 to the output shaft of the pushing motor 41, the synchronous belt 44 is driven to rotate, thereby driving the folding push rod 8 fixedly connected to the synchronous belt 44 to perform linear reciprocating motion, thereby realizing the function of the folding push rod 8 pushing the tail end of the floor forward and then resetting.

[0053] Furthermore, it should be noted that the purpose of setting the folding push rod 8 is to prevent interference with the short-side grinding rod 57 of the short-side grinding mechanism 5. Therefore, when the short-side grinding rod 57 moves, the folding push rod 8 is in a folded state. After the short-side of the floor is ground and the short-side grinding rod 57 is reset, it extends through the electric hydraulic cylinder 58, causing the push rod 81 to rotate 90 degrees and be in a vertical state at the end of the floor. It is then pushed forward from the end of the floor by the linear slide rail assembly 510 at its bottom and the drive of the push mechanism 4. Through the above structural setting, the problem that the long-side grinding of the floor requires a pushing force, which the existing automatic conveyor belt 12 cannot meet by transmitting through friction, is effectively solved. This effectively provides a reasonable and uniform pushing force for the floor, which is beneficial to the quality of the long-side grinding of the floor, thereby effectively improving the quality of the produced products.

[0054] A pressure roller 15 is fixedly installed between the two flow bars 14 and near the back of the long side grinding mechanism 3. The top surface of the processing floor 7 is in close contact with the bottom of the pressure roller 15. A set of guide plates 13 is provided on the top of the conveying device 1 and near the back of the long side grinding mechanism 3 and the short side grinding mechanism 5 respectively. Each set of guide plates 13 consists of two symmetrically arranged guide plates 13. A dust cover 6 is provided on the top of the conveying device 1, which covers the entire area except for the feeding trough 2. A recycling box 11 is fixedly installed at the bottom of the support frame 17 and corresponding to the long side grinding mechanism 3 and the short side grinding mechanism 5.

[0055] Specifically, such as Figure 8 As shown, to make the device safer and easier to clean, and to prevent damage to the surrounding working environment, a dustproof cover 6 is installed on the top of the device, and a recycling box 11 is installed at the bottom inside the support frame 17. This effectively prevents wood chips from flying and polluting the surrounding environment during the floor sanding process, thus affecting the health of the workers. At the same time, the recycling box 11 collects the wood chips, thereby reducing the physical exertion of the workers in cleaning after the work is completed, thus ensuring the cleanliness of the production environment.

[0056] Example 2

[0057] Specifically, such as Figure 9 As shown, a method of using an automatic edge-grinding device for floor processing includes the following steps:

[0058] S1, Processing flooring 7 - Loading materials.

[0059] First, the neatly stacked processing floorboards 7 are placed inside the feeding trough 2 by manual feeding. The processing floorboards 7 are then conveyed out one by one from the slot at the bottom of the feeding trough 2 by the automatic conveyor belt 12. When the number of processing floorboards 7 decreases, manual feeding is then performed again, and this cycle is repeated.

[0060] S2, Short edge polishing.

[0061] A single processing board 7, conveyed by the automatic conveyor belt 12, is transported to the short-side sanding mechanism 5. After its front end is detected by an infrared beam sensor, the clamping block 59 is driven to descend by the electric hydraulic cylinder 58 to press the processing board. The short-side sanding rod 57 is driven to rotate by the bidirectional motor 51, which in turn drives the rotating gear 53 to reciprocate on the tooth surface of the drive rack 55. This causes the sliding bracket 52 and the short-side sanding rod 57 to reciprocate and rotate to sand the front end of the current processing board and the tail end of the previous processing board.

[0062] S3, Long edge polishing.

[0063] After the end of the processed floorboard 7 is sanded, the short side sanding rod 57 of the short side sanding mechanism 5 returns to one side. At this time, the electric telescopic rod 82 of the folding push rod 8 drives the push rod 81 to stand up in a folded state and is exactly at the bottom of the processed floorboard 7. Then, the push motor 41 of the push mechanism 4 drives the synchronous wheel 43 to drive the synchronous belt 44 to move, thereby driving the folding push rod 8 to push the processed wood board on the surface of the two sets of flow strips 14 into the long side sanding mechanism 3. When the front end of the processed floorboard 7 is close to the long side sanding mechanism 3, it is first guided by the two stacked guide plates 13 and the bottom of the pressure roller 15. Then, the left sanding rod 35 and the right sanding rod 37 on both sides of the path sand the long sides of the processed floorboard 7. The debris generated during the sanding process will fall into the recycling box 11 for centralized recycling.

[0064] S4. Processing complete, material discharged.

[0065] After the long edge is polished, the processing floor 7 is pushed forward by the pushing mechanism 4 until it tilts due to its own weight and enters the discharge slide plate 16. After passing through the discharge slide plate 16, it slides into the transfer trolley and is then manually transferred, thus completing the automatic edge polishing process of the floor 7 in one operation.

[0066] As can be seen from the explanation of how to use this device, it only requires two manual workstations, namely the material feeding station and the finished product transfer station, to realize the fully automatic grinding process of the base plate 83. This will improve the production efficiency of enterprises, enhance the quality of finished products, reduce the scrap rate, and save production costs for enterprises, which can be described as having many benefits.

6. A method of using an automatic edge grinding device for floor processing, applied to the automatic edge grinding device for floor processing as described in any one of claims 1-5, characterized in that, Includes the following steps: S1. Processing flooring materials First, the neatly stacked processing floorboards are placed into the feeding trough by manual feeding. Then, the processing floorboards are conveyed out one by one from the slot at the bottom of the feeding trough by an automatic conveyor belt. When the number of processing floorboards decreases, manual feeding is then carried out again, and this cycle is repeated. S2, Short edge polishing. A single processing board is conveyed by an automatic conveyor belt to the short-side sanding mechanism. After its front end is detected by an infrared beam sensor, the clamping block is driven down by an electric hydraulic cylinder to press the processing board. The short-side sanding rod is driven to rotate by a bidirectional motor, which in turn drives the rotating gear to reciprocate on the tooth surface of the drive rack. This causes the sliding bracket and the short-side sanding rod to rotate and reciprocate to sand the front end of the current processing board and the tail end of the previous processing board. S3, Long edge polishing. After the end of the processed floorboard is sanded, the short-side sanding rod of the short-side sanding mechanism returns to its original position and tilts to one side. At this time, the electric telescopic rod of the folding push rod drives the push rod to stand up in a folded state and is exactly at the bottom of the processed floorboard. The push motor of the push mechanism drives the synchronous wheel to drive the synchronous belt to move, thereby driving the folding push rod to push the processed wood board on the surface of the two sets of flow strips into the long-side sanding mechanism. When the front end of the processed floorboard is close to the long-side sanding mechanism, it is first guided by the two stacked guide plates and the bottom of the pressure roller. Then, the left and right sanding rods on both sides of the path sand the two long sides of the processed floorboard. The debris generated during the sanding process will fall into the recycling box for centralized recycling. S4. Processing complete, material discharged. After the long edge is sanded, the processed floorboard continues to be pushed forward by the pushing mechanism until it tilts due to its own weight and enters the discharge slide plate. After passing through the discharge slide plate, it slides into the transfer trolley and is then manually transferred, thus completing a full one-time automatic edge sanding process for the floorboard.
