Description

Technical Field

[0001] This invention relates to the field of furniture processing, and in particular to a process for sanding the sides of wooden boards. Background Technology

[0002] Before splicing, the raw wood planks need to be cut. After cutting, burrs will appear on the sides of the planks, which will adversely affect the subsequent splicing process. Therefore, the sides of the planks need to be sanded. Sanding with small handheld sanding equipment is not only inefficient but also cannot guarantee consistent quality. Traditional sanding devices are larger and can mostly only sand the straight edge of one side of the plank, usually requiring a second sanding, resulting in low efficiency.

[0003] The purpose of this invention is to provide a wood panel side sanding process that uses miniaturized sanding equipment to simultaneously sand the straight sides of both sides of the wood panel. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wood board side sanding process, which uses a sanding device, the sanding device comprising: A conveying device, the conveying device including at least one roller conveyor line, each roller conveyor line including a plurality of rollers, and a gap provided between two adjacent rollers; An operating table, wherein the conveying device and the operating table are arranged sequentially along the conveying direction; A cutting mechanism, comprising a cutting device and two band saws, the two band saws being respectively disposed at both ends of the cutting device, the cutting device driving the two band saws to rotate synchronously in opposite directions, and the end of the band saws away from the cutting device being disposed inside the gap; A grinding mechanism is provided, wherein the cutting mechanism and the grinding mechanism are sequentially arranged on both sides of the roller conveyor line along the conveying direction.

Grinding the plates: The two plates are conveyed to the sanding belt position along the roller conveyor line, and the cut surfaces of the two plates are ground by the sanding belts at both ends of the grinding device. S5. Attaching the boards: Move the two boards towards the workbench, lay the two boards on the workbench, apply glue to the sanded sides of the two boards, align the two boards together, and then use quick clamps to fix the two boards in place.

When the sheet material is conveyed via a roller conveyor line, one end of the sheet material is clamped between two first guide plates, and the other end of the sheet material is clamped between two second guide plates. An operating table, wherein the conveying device and the operating table are arranged sequentially along the conveying direction; A cutting mechanism, comprising a cutting device and two band saws 6, the two band saws 6 being respectively disposed at both ends of the cutting device, the cutting device driving the two band saws 6 to rotate synchronously in opposite directions, and the end of the band saws 6 away from the cutting device being disposed inside the gap; The grinding mechanism, the cutting mechanism and the grinding mechanism are arranged sequentially on both sides of the roller conveyor line along the conveying direction. The cutting mechanism and the grinding mechanism are both arranged between the first guide plate and the second guide plate. The grinding mechanism includes a grinding device and two sanding belts 7. The two sanding belts 7 are respectively arranged at both ends of the grinding device. The grinding device drives the two sanding belts 7 to rotate synchronously in opposite directions. The end of the sanding belt 7 away from the grinding device is arranged inside the gap. The specific method for sanding the sides of a wooden board using the aforementioned sanding equipment is as follows: S0. Equipment inspection: Inspect the wear and tear of the band saw 6 and the sanding belt 7; S1. Adjust the band saw 6 and sanding belt 7: Adjust the end of the band saw 6 and sanding belt 7 closest to the roller conveyor line to the designated position. Adjust the distance between the V-shaped plate 10 and the main support 1 according to the specifications of the plate. Adjust the end of the band saw 6 and sanding belt 7 closest to the roller conveyor line to the designated position. Adjust the angle between the V-shaped plate 10 and the connecting rod 8 according to the side cutting angle of the plate.

[0022] S2, Plate feeding: Place two plates on two roller conveyor lines respectively, and transport the plates toward the operating table through the roller conveyor lines; S3. Cutting the board: The two boards are conveyed to the band saw 6 position along the roller conveyor line, and the sides of the two boards are cut by the band saw 6 at both ends of the cutting device. S4. Grinding the plates: The two plates are conveyed to the sanding belt 7 along the roller conveyor line. The cut surfaces of the two plates are then ground by the sanding belts 7 at both ends of the grinding device. S5. Attaching the boards: Move the two boards towards the workbench, lay the two boards on the workbench, apply glue to the sanded sides of the two boards, align the two boards together, and then use quick clamps to fix the two boards in place.

[0023] The band saw 6 moves vertically downwards at the end furthest from the cutting device, and the sanding belt 7 moves vertically downwards at the end furthest from the grinding device.

[0024] Both the cutting device and the grinding device include: a main support 1, two reversing shafts 3, a drive device 2, and two auxiliary supports 4. The drive device 2 is located at the lower end of the main support 1. Both reversing shafts 3 are rotatably located at the upper end of the main support 1. The two reversing shafts 3 are connected in a transmission manner, and their rotation directions are opposite. The drive device 2 is connected in a transmission manner to either reversing shaft 3. One end of the auxiliary support 4 is located on the main support 1, and the other end of the auxiliary support 4 is located inside the gap. Both the upper and lower ends of the auxiliary support 4 are provided with driven wheels 5. The ends of the band saw 6 and the sanding belt 7 are respectively located on the reversing shaft 3 and the driven wheel 5.

[0025] The reversing shaft 3 includes a first transmission wheel 15, a gear 16, and a second transmission wheel 17. The first transmission wheel 15, the gear 16, and the second transmission wheel 17 are connected sequentially in a direction away from the main support 1. The gears 16 of the two reversing shafts 3 mesh with each other. The first transmission wheel 15 is connected to the drive device 2. One end of the band saw 6 and the sanding belt 7 is located on the second transmission wheel 17.

[0026] The driving device 2 includes a drive motor, which is connected to the first transmission wheel 15 via belt drive.

[0027] The secondary support 4 includes a connecting rod 8, a fastening bolt 11, and a V-shaped plate 10. One end of the connecting rod 8 is hinged to the V-shaped plate 10, and the other end of the connecting rod 8 is disposed on the main support 1. The fastening bolt 11 is threaded to the connecting rod 8. The V-shaped plate 10 has an arc-shaped through hole 14, and the fastening bolt 11 passes through the arc-shaped through hole 14.

[0028] The V-shaped plate 10 is provided with a fixing plate 12, which is perpendicular to the V-shaped plate 10. The surface of the fixing plate 12 away from the main support 1 is parallel to the tangent of the driven wheel 5 away from the main support 1.

[0029] The main support 1 is provided with a sleeve 9, and the connecting rod 8 passes through the sleeve 9. The connecting rod 8 and the sleeve 9 are detachably connected.

[0030] The cutting and polishing device further includes a swing arm and a tension wheel 13, wherein the tension wheel 13 is rotatably mounted on the swing arm, and one end of the swing arm is hinged to the main support 1.

[0031] Because a lot of sawdust and dust are generated during the cutting and sanding of wood, some traditional sanding and cutting devices will cause sawdust to fly upwards and outwards in all directions, resulting in a large amount of sawdust accumulating on the surface of the wood.

[0032] In this invention, a drive motor is connected to the first transmission wheel 15 via a transmission belt. The drive motor drives one of the reversing shafts 3 to rotate via the transmission belt. Since the two reversing shafts 3 are connected by a gear 16, when one reversing shaft 3 rotates, the other reversing shaft 3 will also rotate synchronously, and the rotation directions of the two reversing shafts 3 are opposite. When the two reversing shafts 3 rotate, they will drive the band saw 6 or the sanding belt 7 to rotate. When the band saw 6 or the sanding belt 7 rotates, the vector of one end of the band saw 6 or the sanding belt 7 located inside the gap is vertically downward. The wood chips generated by the band saw 6 and the sanding belt 7 during operation will fly downward to the ground below the wood, preventing the wood chips generated by the band saw 6 and the sanding belt 7 from accumulating on the upper surface of the wood.

[0033] Since wood requires a cutting machine for cutting and a sanding machine for sanding, purchasing separate cutting and sanding machines would increase costs. Furthermore, if either machine breaks down, it needs to be repaired separately, and because parts are not interchangeable, maintenance is difficult and costly.

[0034] Both the cutting and grinding devices utilize a drive motor to rotate one of the reversing shafts 3 via belt drive. The two reversing shafts 3 are connected by a gear 16, meaning that when one reversing shaft 3 rotates forward, the other will rotate in reverse. The rotation of the two reversing shafts 3 drives the two band saws 6 or sanding belts 7 to rotate; when one band saw 6 or sanding belt 7 rotates forward, the other will rotate in reverse. The cutting and grinding devices have identical structures, and their components are interchangeable. Only the band saw 6 and sanding belt 7 need to be purchased separately, reducing maintenance difficulty and costs.

[0035] The sheet material moves in a straight line along a roller conveyor, with cutting and grinding mechanisms installed on both sides of the conveyor. As the sheet material moves along the conveyor, the two cutting and two grinding mechanisms sequentially cut and grind both sides of the sheet material. Furthermore, the movement vector of the end of the band saw 6 or sanding belt 7 that contacts the sheet material is vertically downward, ensuring balanced force on the two long sides of the sheet material during processing. This prevents the sheet material from vibrating due to unequal forces on both sides during cutting and grinding, ensuring that cutting and grinding operations can proceed smoothly and simultaneously.

[0036] This invention drives the band saws 6 and sanding belts 7 at both ends to rotate in opposite directions via a reversing shaft 3. The two band saws 6 and sanding belts 7 sand the long sides of the wooden boards on the two roller conveyor lines, ensuring that the sanding of the boards is balanced on both sides and guarantees consistent sanding results. In one embodiment, the drive motor is positioned directly below the roller conveyor line. Cutting devices are positioned on both sides of the roller conveyor line. There is one band saw 6, with both ends of the band saw 6 mounted on the driven wheels 5 of the V-shaped plates 10 of the two cutting devices. The two ends of the band saw 6 contact the two long sides of the material. There is one sanding belt 7. Grinding devices are positioned on both sides of the roller conveyor line. The two ends of the sanding belt 7 are mounted on the driven wheels 5 of the V-shaped plates 10 of the two grinding devices. The two ends of the sanding belt 7 contact the two long sides of the material, and the upper end of the sanding belt 7 contacts the upper surface of the material.

[0037] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should all be considered to be within the scope of this specification.
