Description

Technical Field

[0001] This invention relates to the field of wood panel edge grinding technology, specifically to a double-sided synchronous edge grinding machine that adapts to the thickness of the wood panel. Background Technology

[0002] In the wood processing industry, edge sanding is a crucial process for improving the appearance quality and assembly precision of boards. Traditional edge sanding equipment is mostly single-sided, requiring separate sanding of both edges. This is not only inefficient, but the positioning errors during the two sanding processes can easily lead to poor parallelism and dimensional consistency of the edges. Furthermore, the sanding heads in existing equipment are mostly fixed, unable to adapt to thickness variations caused by manufacturing processes, resulting in under-sanding or over-sanding of the edges, which affects the quality of subsequent gluing and edge banding processes.

[0003] Furthermore, traditional edge-grinding equipment often uses a single conveyor belt to directly support the board. Under the weight of the board, the conveyor belt is prone to sagging and deformation, causing the board to deviate during transport and further exacerbating the deviation in grinding accuracy. Wood chips generated during the edge-grinding process tend to accumulate inside the equipment, affecting the normal operation of components and polluting the operator's working environment, making equipment maintenance difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a double-sided synchronous edge grinding machine for wood processing that adapts to the thickness of the board, in order to solve the problem mentioned in the background art that most traditional board edge grinding equipment has a single-sided grinding structure, which requires grinding both sides of the board separately. This not only results in low processing efficiency, but also the positioning error of the board during the two grinding processes can easily lead to poor parallelism and dimensional consistency of the two sides of the edge.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-sided synchronous edge grinding machine for wood processing with adaptive board thickness, comprising: a base and a chip guide frame fixedly installed above the base, wherein a conveying component is installed between opposite surfaces of the chip guide frame via a motor drive, and edge grinding components are fixedly installed on both sides of the top of the chip guide frame, the edge grinding components being arranged on both sides of the conveying component; the operator, according to the width of the board to be processed, activates the adjustment drive seat of the edge grinding components on both sides, causing them to move along the edge grinding guide rail, adjusting the spacing between the grinding heads to match the width of the board, and simultaneously setting the reference position of the grinding heads according to the nominal thickness of the board, at which point the adaptive spring is in a pre-compressed state, reserving floating space for subsequent thickness adaptive adjustment.

[0006] The chip guide frame includes a supporting crossbeam, legs, and a chip receiving plate. The legs are fixedly installed on both sides of the supporting crossbeam, and the chip receiving plate is disposed between the legs and the base. The chip receiving plate is an inclined stainless steel plate with its discharge end extending to the outside of the base to collect processing waste. Furthermore, the conveying assembly includes a conveyor belt, auxiliary guide wheels, a support bar, a conveying drive component, a mounting frame, and conveying rollers. The mounting frame is fixedly installed between opposite faces of the supporting crossbeam. Wood chips and dust generated during the edge grinding process fall onto the chip receiving plate below the chip guide frame under gravity. The inclined design of the chip receiving plate allows the waste to automatically slide towards the collection container outside the equipment. The edge-ground board continues to be conveyed by the conveyor belt and discharged from the discharge end of the equipment.

[0007] Furthermore, the conveyor belt, conveyor drive, auxiliary guide wheel, support bar, and conveyor idler are all mounted on the mounting frame. The conveyor drive drives the conveyor belt to rotate, and the conveyor idler is configured with a double-layer structure that is frictionally adapted to the surface of the conveyor belt.

[0008] Furthermore, the mounting frame is a frame structure, the frame strips are symmetrically arranged along both sides of the mounting frame, the conveyor rollers are evenly distributed below the conveyor belt along the width direction of the mounting frame, and the auxiliary guide wheels are arranged on the side of the mounting frame to guide the conveyor belt to run smoothly.

[0009] Furthermore, the conveying idler includes an idler shaft, a mounting base, a support beam, and a bearing seat. The support beam is fixedly mounted on the mounting frame to support and assist in conveying the sheet metal. The conveying idlers of the conveying assembly are evenly distributed along the underside of the conveyor belt. The rotation of the idler shaft supports the sheet metal, effectively reducing the sagging deformation of the conveyor belt. Lateral deviation is less likely to occur during sheet metal conveying, ensuring the alignment accuracy between the grinding head and the edge of the sheet metal, and reducing the scrap rate.

[0010] Furthermore, the mounting base is fixedly installed on the support beam, the bearing seat is fixedly installed on the mounting base, and both ends of the idler roller shaft are rotatably installed in the bearing seat. The outer surface of the idler roller shaft is in contact with the surface of the conveyor belt to reduce wear and vibration during conveyor belt operation. The operator places the wooden board to be processed at the feed end of the conveyor assembly. The support bars support both sides of the board. The conveyor drive is activated, driving the conveyor belt to rotate. The conveyor idler rollers, through the rotation of their shafts, support the conveyor belt and the board, reducing the running resistance and deformation of the conveyor belt and preventing the board from shifting during transport.

[0011] Furthermore, the edge grinding components are symmetrically arranged on the support crossbeams on both sides of the chip guide frame, including an edge grinding guide rail, an adjusting drive seat, an edge grinding wheel seat, a grinding head, and a connecting seat. The edge grinding guide rail is fixedly installed on the support crossbeams, the adjusting drive seat is slidably installed on the edge grinding guide rail, and the edge grinding wheel seat is connected to the adjusting drive seat through the connecting seat. The symmetrical arrangement of the edge grinding components on both sides allows for simultaneous grinding of both edges of the sheet metal, increasing processing efficiency by more than double compared to traditional single-sided, step-by-step grinding equipment. Simultaneously, the precise positioning of the adjusting drive seat allows for quick adaptation to sheet metal of different widths, reducing equipment changeover and debugging time.

[0012] Furthermore, the adjustment drive seat is a servo motor-driven linear slide structure that can reciprocate along the length of the grinding guide rail to adjust the distance between the grinding head and the edge of the board, adapting to boards of different widths. The board enters the grinding station with the conveyor belt, and the grinding heads on both sides simultaneously contact the edge of the board. When there is a thickness error in the board, the side of the board applies pressure to the grinding head, causing the grinding head to slide along the direction of the mating groove. The adaptive spring is further compressed or rebounded, ensuring that the grinding head always contacts the edge of the board, achieving adaptive grinding in the thickness direction. Simultaneously, the adjustment drive seat maintains a stable lateral position of the grinding head, ensuring uniform grinding allowance on both sides of the board edge.

[0013] Furthermore, the grinding wheel seat includes a guide slide, a mating groove, and an adaptive spring. The adaptive spring is disposed within the guide slide, allowing the grinding head to adaptively float along the thickness direction of the sheet material. The grinding head is mounted on the grinding wheel seat and is used to simultaneously grind both sides of the sheet material's edges. Through the cooperation between the adaptive spring and the mating groove within the grinding wheel seat, the grinding head can adaptively float along the thickness direction of the sheet material, adapting to thickness errors and avoiding insufficient or over-grinding of the edges due to uneven sheet thickness, thereby improving the smoothness and consistency of the sheet material's edges.

[0014] Furthermore, the guide slide and the adjustment drive seat are hinged together by a connecting seat, the docking groove is opened on the inner side wall of the guide slide, the adaptive spring is installed in the docking groove, and the rotating shaft of the grinding head is installed in the docking groove by a bearing.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (i) This wood board processing adaptive board thickness double-sided synchronous edge grinding machine, the operator starts the adjustment drive seat of the edge grinding components on both sides according to the width of the board to be processed, so that it moves along the edge grinding guide rail, adjusts the distance between the grinding heads to match the width of the board, and at the same time, according to the nominal thickness of the board, initially sets the reference position of the grinding head. At this time, the adaptive spring is in a pre-compressed state, reserving floating space for subsequent thickness adaptive adjustment.

[0016] (ii) The wood board processing adaptive board thickness double-sided synchronous edge grinding machine generates wood chips and dust during the edge grinding process. Under the action of gravity, the wood chips and dust fall into the chip receiving plate under the chip guide frame. The inclined design of the chip receiving plate allows the waste chips to automatically slide to the collection container outside the equipment. The edge-ground boards continue to be conveyed by the conveyor belt and discharged from the discharge end of the equipment. The wood chips generated during the edge grinding process are automatically guided to the outside of the equipment to avoid the accumulation of waste chips inside the equipment and affecting the operation of the parts.

[0017] (III) This wood board processing adaptive double-sided synchronous edge grinding machine for wood board thickness allows the operator to place the wood board to be processed at the feed end of the conveyor assembly. The support bars support both sides of the board. The conveyor drive is activated, driving the conveyor belt to rotate. The conveyor rollers, through the rotation of their shafts, support the conveyor belt and the board, reducing the running resistance and deformation of the conveyor belt and preventing the board from shifting during transport. The conveyor rollers of the conveyor assembly are evenly distributed along the underside of the conveyor belt. The rotation of the roller shafts supports the board, effectively reducing the sagging deformation of the conveyor belt. Lateral shift of the board is less likely to occur during transport, ensuring the alignment accuracy between the grinding head and the edge of the board and reducing the scrap rate.

[0018] (iv) This wood board processing adaptive double-sided synchronous edge grinding machine for board thickness: the board enters the edge grinding station with the conveyor belt, and the grinding heads on both sides simultaneously contact the edge of the board. When there is a thickness error in the board, the side edge of the board will apply pressure to the grinding head. The grinding head drives the edge grinding wheel to slide along the direction of the mating groove, and the adaptive spring is further compressed or rebounded, so that the grinding head is always in contact with the edge of the board, realizing adaptive grinding in the thickness direction of the board. At the same time, the drive seat is adjusted to keep the lateral position of the grinding head stable, ensuring that the grinding allowance on both sides of the board is uniform.

[0019] (v) This wood board processing adaptive board thickness double-sided synchronous edge grinding machine, through the cooperation of the adaptive spring in the edge grinding wheel seat and the docking groove, allows the grinding head to float adaptively along the board thickness direction, which can adapt to the thickness error of the board and avoid the problem of insufficient or over-grinding of the edges due to uneven board thickness, thereby improving the processing flatness and consistency of the board edges.

[0022] Example 1, as Figures 1 to 9 As shown, the present invention provides a technical solution: a double-sided synchronous edge grinding machine for wood processing with adaptive board thickness, comprising: a base 1 and a chip guide frame 2 fixedly installed above the base 1. A conveying component 3 is installed between opposite surfaces of the chip guide frame 2 via a motor drive. Edge grinding components 4 are fixedly installed on both sides of the top of the chip guide frame 2. The edge grinding components 4 are arranged on both sides of the conveying component 3. According to the width of the board to be processed, the operator starts the adjustment drive seat 42 of the edge grinding components 4 on both sides, so that it moves along the edge grinding guide rail 41, adjusts the spacing between the grinding heads 44 to match the width of the board, and at the same time, according to the nominal thickness of the board, initially sets the reference position of the grinding heads 44. At this time, the adaptive spring 433 is in a pre-compressed state, reserving floating space for subsequent thickness adaptive adjustment.

[0023] The chip guide frame 2 includes a support crossbeam 21, legs 22 and chip receiving plate 23. The legs 22 are fixedly installed on both sides of the support crossbeam 21. The chip receiving plate 23 is disposed between the legs 22 and the base 1. The chip receiving plate 23 is an inclined stainless steel plate with its discharge end extending to the outside of the base 1 to receive processing waste chips.

[0024] The conveying assembly 3 includes a conveyor belt 31, auxiliary guide wheels 32, a support bar 33, a conveying drive component 34, a mounting frame 35, and conveying idlers 36. The mounting frame 35 is fixedly installed between the opposite surfaces of the supporting crossbeam 21. Wood chips and dust generated during the edge grinding process fall under gravity into the chip receiving plate 23 below the chip guide frame 2. The inclined design of the chip receiving plate 23 causes the waste chips to automatically slide towards the collection container outside the equipment. The edge-ground board continues to be conveyed by the conveyor belt 31 and discharged from the outlet end of the equipment.

[0025] Example 2, based on Example 1, such as Figures 3 to 5 As shown, the conveyor belt 31, the conveyor drive unit 34, the auxiliary guide wheel 32, the support bar 33 and the conveyor idler 36 are all mounted on the mounting frame 35. The conveyor drive unit 34 drives the conveyor belt 31 to rotate. The conveyor idler 36 is set with a double-layer structure and is frictionally adapted to the surface of the conveyor belt 31.

[0026] The mounting frame 35 has a frame structure. The support strips 33 are symmetrically arranged along both sides of the mounting frame 35. The conveyor rollers 36 are evenly distributed below the conveyor belt 31 along the width direction of the mounting frame 35. The auxiliary guide wheels 32 are arranged on the side of the mounting frame 35 to guide the conveyor belt 31 to operate smoothly.

[0027] The conveying idler roller 36 includes an idler roller shaft 361, a mounting base 362, a support beam 363, and a bearing seat 364. The support beam 363 is fixedly mounted on the mounting frame 35 and is used to support and assist in conveying the sheet metal. The conveying idler rollers 36 of the conveying assembly 3 are evenly distributed below the conveyor belt 31. The rotation of the idler roller shaft 361 supports the sheet metal, effectively reducing the sagging deformation of the conveyor belt 31. Lateral displacement is less likely to occur during the conveying of the sheet metal, ensuring the alignment accuracy between the grinding head 44 and the edge of the sheet metal, and reducing the scrap rate.

[0028] The mounting base 362 is fixedly mounted on the support beam 363, and the bearing seat 364 is fixedly mounted on the mounting base 362. The two ends of the idler roller shaft 361 are rotatably mounted within the bearing seat 364. The outer surface of the idler roller shaft 361 is in contact with the surface of the conveyor belt 31 to reduce wear and vibration during conveyor belt 31 operation. The operator places the wooden board to be processed at the feed end of the conveyor assembly 3. The support bar 33 supports both sides of the board. The conveyor drive component 34 is activated, driving the conveyor belt 31 to rotate. The conveyor rollers 36, through the rotation of the idler roller shaft 361, support the conveyor belt 31 and the board, reducing the running resistance and deformation of the conveyor belt 31 and preventing deviation during board conveying.

[0029] Example 3, based on Examples 1 and 2, such as Figures 7 to 9As shown, the edge grinding assembly 4 is symmetrically arranged on the support crossbeams 21 on both sides of the chip guide frame 2. It includes an edge grinding guide rail 41, an adjusting drive seat 42, an edge grinding wheel seat 43, a grinding head 44, and a connecting seat 45. The edge grinding guide rail 41 is fixedly installed on the support crossbeams 21, the adjusting drive seat 42 is slidably installed on the edge grinding guide rail 41, and the edge grinding wheel seat 43 is connected to the adjusting drive seat 42 via the connecting seat 45. The symmetrical arrangement of the edge grinding assemblies 4 on both sides allows for simultaneous grinding of both edges of the sheet metal, increasing processing efficiency by more than double compared to traditional single-sided step-by-step grinding equipment. Furthermore, the precise positioning of the adjusting drive seat 42 allows for quick adaptation to sheet metal of different widths, reducing equipment changeover and debugging time.

[0030] The adjusting drive seat 42 is a servo motor-driven linear slide structure that can reciprocate along the length of the grinding guide rail 41 to adjust the distance between the grinding head 44 and the edge of the board, adapting to boards of different widths. The board enters the grinding station with the conveyor belt 31, and the grinding heads 44 on both sides simultaneously contact the edge of the board. When there is a thickness error in the board, the side of the board applies pressure to the grinding head 44, causing the grinding head 44 to drive the grinding wheel seat 43 to slide along the direction of the mating groove 432. The adaptive spring 433 is further compressed or rebounds, ensuring that the grinding head 44 always fits against the edge of the board, achieving adaptive grinding in the thickness direction of the board. Simultaneously, the adjusting drive seat 42 maintains the lateral position of the grinding head 44 stably, ensuring that the grinding allowance on both sides of the board is uniform.

[0031] The grinding wheel seat 43 includes a guide slide 431, a mating groove 432, and an adaptive spring 433. The adaptive spring 433 is disposed within the guide slide 431, allowing the grinding head 44 to adaptively float along the thickness direction of the sheet material. The grinding head 44 is mounted on the grinding wheel seat 43 and is used to simultaneously grind both sides of the sheet material's edges. Through the cooperation between the adaptive spring 433 and the mating groove 432 within the grinding wheel seat 43, the grinding head 44 can adaptively float along the thickness direction of the sheet material, adapting to thickness errors and avoiding insufficient or over-grinding of the edges due to uneven sheet thickness, thereby improving the flatness and consistency of the sheet material's edges.

[0032] The guide slide 431 and the adjustment drive seat 42 are hinged together by the connecting seat 45. The docking groove 432 is opened on the inner side wall of the guide slide 431. The adaptive spring 433 is installed in the docking groove 432. The rotating shaft of the grinding head 44 is installed in the docking groove 432 by the bearing.

[0033] In use, the operator starts the adjustment drive seat 42 of the two grinding components 4 according to the width of the board to be processed, so that it moves along the grinding guide rail 41 and adjusts the distance between the grinding heads 44 to match the width of the board. At the same time, according to the nominal thickness of the board, the reference position of the grinding head 44 is initially set. At this time, the adaptive spring 433 is in a pre-compressed state, reserving floating space for subsequent thickness adaptive adjustment.

[0034] The symmetrically arranged edge grinding components 4 on both sides can simultaneously complete the grinding of both edges of the board, increasing processing efficiency by more than double compared to traditional single-sided step-by-step grinding equipment. Furthermore, by adjusting the precise positioning of the drive seat 42, it can quickly adapt to boards of different widths, reducing equipment changeover and debugging time.

[0035] By cooperating with the adaptive spring 433 in the grinding wheel seat 43 and the mating groove 432, the grinding head 44 can adaptively float along the thickness direction of the plate, which can adapt to the thickness error of the plate and avoid insufficient or over-grinding of the edge due to uneven plate thickness, thereby improving the processing flatness and consistency of the plate edge.

[0036] The operator places the wooden board to be processed at the feed end of the conveyor assembly 3. The support bar 33 supports both sides of the board. The conveyor drive 34 is started, driving the conveyor belt 31 to run. The conveyor roller 36 supports the conveyor belt 31 and the board through the rotation of the roller shaft 361, reducing the running resistance and deformation of the conveyor belt 31 and preventing the board from deviating during the conveying process.

[0037] The conveying rollers 36 of the conveying assembly 3 are evenly distributed below the conveyor belt 31. The rotation of the roller shaft 361 supports the plate, effectively reducing the sagging deformation of the conveyor belt 31. The plate is less likely to shift laterally during the conveying process, ensuring the alignment accuracy between the grinding head 44 and the edge of the plate and reducing the scrap rate.

[0038] The sheet material enters the edge grinding station via conveyor belt 31. Grinding heads 44 on both sides simultaneously contact the edge of the sheet material. When there is a thickness error in the sheet material, the side edge of the sheet material applies pressure to the grinding head 44. The grinding head 44 drives the grinding wheel seat 43 to slide along the direction of the mating groove 432. The adaptive spring 433 is further compressed or rebounds, ensuring that the grinding head 44 always contacts the edge of the sheet material, achieving adaptive grinding in the thickness direction. Simultaneously, the drive seat 42 is adjusted to maintain the lateral position of the grinding head 44, ensuring that the grinding allowance on both sides of the sheet material is uniform.

[0039] The wood chips and dust generated during the edge grinding process fall into the chip receiving plate 23 below the chip guide frame 2 under the action of gravity. The inclined design of the chip receiving plate 23 causes the waste chips to automatically slide to the collection container outside the equipment. The edge-ground board continues to be conveyed by the conveyor belt 31 and discharged from the discharge end of the equipment.

[0040] The inclined chip receiving plate 23 installed below the chip guide frame 2 can automatically guide the wood chips generated during the edge grinding process to the outside of the equipment, so as to avoid the accumulation of waste chips inside the equipment and affect the operation of the parts.

[0041] After the sheet metal processing is completed, the conveying drive 34 and the grinding head 44 stop running. The adjustment drive seat 42 drives the edge grinding assembly 4 to reset to the initial position. The operator can clean the residual waste on the chip receiving plate 23 and check the elasticity of the bearing seat 364 and the adaptive spring 433 of the conveying roller 36 to ensure the stable operation of the equipment in the future.
