Attaching the plates: Push the two plates toward the operating table, lay the two plates on the operating table, apply glue to the polished sides of the two plates, butt-join the two plates, and after joining, use quick clamps to fix the two plates.

[0023] The movement direction of the band saw 6 at one end away from the cutting device is vertically downward, and the movement direction of the sanding belt 7 at one end away from the grinding device is vertically downward.

[0024] The cutting device and the grinding device both include: a main bracket 1, two reversing shafts 3, a driving device 2, and two sub-brackets 4. The driving device 2 is arranged at the lower end of the main bracket 1, and the two reversing shafts 3 can be rotatably arranged at the upper end of the main bracket 1. The two reversing shafts 3 are transmission connected, and the rotation directions of the two reversing shafts 3 are opposite. The driving device 2 is transmission connected to any one of the reversing shafts 3; one end of the sub-bracket 4 is arranged on the main bracket 1, and the other end of the sub-bracket 4 is arranged inside the gap. The sub-bracket 4 is provided with a driven wheel 5 at both the upper and lower ends, and the two ends of the band saw 6 and the sanding belt 7 are respectively arranged 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 in sequence in a direction away from the main bracket 1. The gears 16 of the two reversing shafts 3 are meshed with each other. The first transmission wheel 15 is transmission-connected to the driving device 2, and the band saw 6 and one end of the sanding belt 7 are arranged on the second transmission wheel 17.

[0026] The driving device 2 comprises a driving motor, and the driving motor is connected to the first transmission wheel 15 by belt transmission.

[0027] The auxiliary bracket 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 arranged on the main bracket 1. The fastening bolt 11 is threadedly connected to the connecting rod 8. The V-shaped plate 10 is provided with 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 , and the fixing plate 12 is perpendicular to the V-shaped plate 10 . The surface of the fixing plate 12 away from the main bracket 1 is parallel to the tangent of one end of the driven wheel 5 away from the main bracket 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 device and the grinding device further include: a swing arm and a tension wheel 13 . The tension wheel 13 is rotatably arranged on the swing arm, and one end of the swing arm is hinged to the main bracket 1 .

[0031] Since a large amount of sawdust and dust will be generated during the process of cutting and grinding wood, the sawdust generated by some traditional grinding devices and cutting devices during operation will fly around the wood, causing a large amount of sawdust to accumulate on the surface of the wood.

[0032] In the present invention, the driving motor is connected to the first transmission wheel 15 through a transmission belt, and the driving motor drives one of the reversing shafts 3 to rotate through the transmission belt. Since the two reversing shafts 3 are connected through the 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, and the wood chips generated when the band saw 6 and the sanding belt 7 are in operation will fly downward to the ground below the wood, so as to prevent the wood chips generated when the band saw 6 and the sanding belt 7 are in operation from accumulating on the upper surface of the wood.

[0033] Since wood needs to be cut by a cutting machine during the cutting process and needs to be cut by a grinder during the grinding process, purchasing a cutting machine and a grinder separately will increase the cost, and once the cutting machine and the grinder are damaged, they need to be repaired separately. Since the parts of the two are not interchangeable, the maintenance difficulty and maintenance cost are high.

[0034] The cutting device and the grinding device both use a driving motor to drive one of the reversing shafts 3 to rotate in the form of belt drive. The two reversing shafts 3 are connected in the form of gear 16 drive. When one reversing shaft 3 rotates forward, the other reversing shaft 3 will reverse. When the two reversing shafts 3 rotate, they will drive the two band saws 6 or abrasive belts 7 to rotate. When one band saw 6 or abrasive belt 7 rotates forward, the other band saw 6 or abrasive belt 7 will reverse. The cutting device and the grinding device have the same structure, and the structural parts of the two can be interchanged. Only the band saw 6 and the abrasive belt 7 need to be purchased separately, which reduces the difficulty and cost of maintenance.

[0035] The plate passes through the roller conveyor line, and cutting mechanisms and grinding mechanisms are provided on both sides of the roller conveyor line. When the plate moves along the roller conveyor line, the two cutting mechanisms and two grinding mechanisms perform cutting and grinding operations on both sides of the plate in turn. The motion vectors of the end of the band saw 6 or the sanding belt 7 that contacts the plate are vertically downward, ensuring that the two long sides of the plate are balanced in force during the processing, avoiding the plate from shaking due to unequal forces on both sides during the cutting and grinding process, and ensuring that the cutting and grinding operations are carried out smoothly at the same time.

[0036] The present invention drives the band saws 6 and the abrasive belts 7 at both ends to rotate in opposite directions through the reversing shaft 3. The two band saws 6 and the abrasive belts 7 grind the long sides of the wooden boards on the two roller conveyor lines, ensuring that the grinding of the boards is balanced on both sides to ensure the consistency of the grinding effect. In one embodiment, the driving motor is arranged directly below the roller conveyor line. The cutting device is arranged on both sides of the roller conveyor line, the number of the band saw 6 is one, and the two ends of the band saw 6 are respectively arranged on the driven wheels 5 of the V-shaped plates 10 of the two cutting devices, and the two ends of the band saw 6 are respectively in contact with the two long sides of the plate. The number of the sanding belt 7 is one, and the grinding device is arranged on both sides of the roller conveyor line, and the two ends of the sanding belt 7 are respectively arranged on the driven wheels 5 of the V-shaped plates 10 of the two grinding devices, and the two ends of the sanding belt 7 are respectively in contact with the two long sides of the plate, and the upper end of the sanding belt 7 is in contact with the upper surface of the plate.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which should be considered as the scope of this specification.
