Description

Technical Field

[0001] The invention relates to the technical field of wood floor cutting, in particular to an adjustable sawing device for processing laminate composite wood floor. Background Art

[0002] Laminate composite wood flooring, commonly known as "diamond board", is a specially treated wood flooring; There are two reasons why irregular boards will be produced during the cutting process. One is that the floor is not or cannot be completely centered during the cutting process, which easily leads to irregular edges and corners on both sides of the board. The other is that the edges of the entire floor will produce irregular corners after cutting. The irregular board still has value for processing and utilization, so it will be cut again. However, due to the special shape of the board, its position after being placed on the cutting equipment cannot correspond to the cutting spacing of the cutting wheel, which will cause more loss and corners of the board after cutting, thus causing waste.

[0016] See also Figure 1-11The present invention provides a technical solution: an adjustable sawing device for processing laminate composite wood flooring, comprising a machine body 1, a cutting assembly 2 and a driving assembly, a plurality of cylinders 11 are fixedly connected to the machine body 1, a fixing frame 12 is fixedly connected to the top of the cylinder 11, a horizontal plate 13 is fixedly connected to the fixing frame 12, a plurality of conveying wheels 14 are arranged at the bottom of the horizontal plate 13, a supporting plate 3 is fixedly connected to the machine body 1, the cutting assembly 2 is fixedly connected to the middle position of the supporting plate 3, a plurality of rollers 9 are rotatably connected to the supporting plate 3, and an adjustment group is arranged in front of the cutting assembly 2; The adjustment group includes a push rod 4 and a contact rod 5, which are respectively located on the left and right sides of the support plate 3. A number of fixed rods 6 are fixedly connected to the side walls of the push rod 4, and sliders 7 are slidably connected inside the fixed rods 6. The tops of the sliders 7 are rotatably connected to contact wheels 29. A number of through grooves are opened on the support plate 3, and the sliders 7 are all located inside the through grooves. A first spring 8 is fixedly connected between the sliders 7 and the inner walls of the fixed rods 6. The contact rod 5 is slidably connected to the support plate 3 through the through grooves, and the push rod 4 is slidably connected to the bottom of the support plate 3. The driving assembly is used to drive the push rod 4 and the contact rod 5 to translate left and right along the support plate 3.

[0017] like Figure 1-Figure 7 As shown: One-time angle adjustment of the plate: Place the plate on the support plate 3 so that the straight edge of the plate is placed close to the contact rod 5, and then use the driving assembly to slide the contact rod 5 to the left along the support plate 3. After the contact rod 5 moves to contact the straight edge of the plate, it pushes the plate and makes the side edge of the plate fit with the left side of the contact rod 5. At this time, the angle of the plate is adjusted once; Secondary angle adjustment of the plate: Then the contact rod 5 will push the plate to move on the roller 9 toward the contact wheel 29 while moving. Because the leftward displacement of the contact wheel 29 and the slider 7 is limited by the first spring 8, when the plate contacts the contact wheel 29, the contact wheel 29 will resist the plate, so that the straight edge of the plate can be completely fitted with the contact rod 5. Then the contact rod 5 continues to move to the limit. At this time, the contact wheel 29 in contact with the plate will be pushed to the left accordingly, and the slider 7 below it will slide to the left along the fixed rod 6 and compress the first spring 8. At this time, the contact wheel 29 follows the left trajectory of the plate and presents a relative displacement, as shown in FIG. Figure 5 As shown, at this time, the contact wheel 29 and the contact rod 5 will clamp the plate; Then, the driving assembly drives the push rod 4 and the contact rod 5 to move to the right at the same time, and the push rod 4 will drive the fixed rod 6 and the contact rod 5 to move to the right synchronously, thereby moving the clamped plate to the right. When the contact rod 5 moves to the right to the initial position, the contact rod 5 and the push rod 4 stop at the same time. At this time, the right side of the plate, that is, the distance between the straight edge and the saw blade of the cutting assembly 2 at the far right is the cutting size of the plate. Then, the cylinder 11 is shortened to drive the fixed frame 12 and the cross plate 13 to drop to the limit. At this time, the conveying wheel 14 will contact the top of the plate. The plate is contacted and a certain downward force is generated, so that the plate after the angle adjustment is fixed between the conveying wheel 14 and the roller 9, and then the driving component drives the push rod 4 to reset to the leftmost side alone. When the push rod 4 moves to the leftmost rear contact wheel 29, it will completely break away from the contact with the plate, and then the conveying wheel 14 rotates to convey the plate from the front to the rear of the support plate 3. When the conveyed plate passes through the cutting component 2, it is cut along the cutting line P, so that the plate can be fully utilized and waste is reduced, and the plate that does not meet the cutting requirements can be directly discarded; According to the present invention, when processing an irregular plate, the plate is pushed by the contact rod 5 to move toward the contact wheel 29, thereby completing the contact between the plate and the contact rod 5, that is, the first angle adjustment. When the plate contacts the contact wheel 29, the reverse resistance of the contact wheel 29 completes the secondary angle adjustment of the plate and enables the plate to be fixed by the contact wheel 29 and the contact rod 5. The individual displacements of the multiple contact wheels 29 adapt to the irregular shape of the plate after contacting the plate, thereby completing the angle adjustment of plates of different shapes and reducing the waste rate when cutting the plate.

[0018] An anti-warping group is provided on one side of the slider 7; The anti-warping group includes a rack rod 15 fixedly connected to the side wall of the slider 7, a pressure plate 16 is slidably connected inside the rack rod 15, a second spring 17 is fixedly connected between the top of the pressure plate 16 and the inner wall of the rack rod 15, a push rod 18 is arranged under the pressure plate 16, the push rod 18 is rotatably connected to the side wall of the fixed rod 6, and a torsion spring 19 is sleeved on the rotating axis of the push rod 18.

[0019] like Figure 8-Figure 10 As shown: In Figure 8 In the state of , the push rod 18 is in a vertical state and its top end supports the pressure plate 16 so that the second spring 17 is in a stretched state. When the contact rod 5 pushes the plate to move to contact with the contact wheel 29 and pushes the contact wheel 29 and the slider 7 to move to the left, the push rod 18 will follow the leftward movement of the slider 7 under the action of the torsion spring 19 and gradually rotate around the side wall of the fixing rod 6. At this time, the pressure plate 16 will gradually drop. When the slider 7 moves to the push rod 18 and separates from the pressure plate 16, the pressure plate 16 will press down the end of the plate, so that the plate can be fixed. As the left side of the plate contacts more and more contact wheels 29, the plate is squeezed more and more, and the downward pressure of multiple pressing plates 16 can limit the plate, thereby preventing the plate from warping. After the conveying wheel 14 presses down and fixes the plate, when the push rod 4 moves to the left relative to the contact rod 5, the contact wheel 29 will gradually separate from the plate. At this time, the slider 7 and the contact wheel 29 will move to the right side of the fixing rod 6 under the elastic reset of the first spring 8 (such as Fig. 9 As shown in the figure), when the bottom end of the pressing plate 16 contacts the inclined push rod 18, the push rod 18 will gradually lift the pressing plate 16, and at the same time, the push rod 18 will rotate to a vertical state, thereby completing the reset.

[0020] A locking group is provided on one side of the pressure plate 16; The locking group includes a pull rod 20, which is slidably connected to the rear end of the pressure plate 16. A one-way gear 21 is rotatably connected to the pull rod 20, and the one-way gear 21 is meshed with the rack rod 15. A third spring 22 is fixedly connected between the pull rod 20 and the pressure plate 16.

[0021] like Figure 8-Figure 11 As shown: When the push rod 18 is in a vertical state, the pressure plate 16 is at the highest point. At this time, the left end of the pull rod 20 is in contact with the side wall protruding in the front-rear direction of the fixed rod 6 and is blocked by the side wall, so that the third spring 22 is in a stretched state. At this time, the one-way gear 21 is not engaged with the rack rod 15 but has a certain distance from the rack rod 15. However, as the plate pushes the contact wheel 29 to the left, the push rod 18 gradually tilts when the slider 7 slides to the left along the fixed rod 6. At this time, the pressure plate 16 and the pull rod 20 will gradually drop, and the third spring 22 will also It will gradually elastically shrink. When the top rod 18 is separated from the bottom end of the pressing plate 16, the pressing plate 16 presses down and fixes the edge of the plate. The third spring 22 is completely elastically reset. At this time, the one-way gear 21 will be engaged with the rack rod 15. The one-way gear 21 can only rotate in one direction, which is used to limit the rise of the pressing plate 16, so that the pressing plate 16 cannot rise, and then the plate and the plates of different thicknesses will not move upward when they are fixed, thereby ensuring that the pressing plate 16 will not move upward when the plate wants to warp, thereby ensuring the limiting effect on the plate; When the conveying wheel 14 presses down and fixes the plate and the push rod 4 moves to the left relative to the contact rod 5, the contact wheel 29 will gradually separate from the plate. When the pull rod 20 moves to the protruding side of the fixing rod 6 and contacts it, it will block the pull rod 20, so that the pull rod 20 and the one-way gear 21 are fixed at this position, and the one-way gear 21 is separated from the rack rod 15, thereby releasing the restriction on the rise of the pressure plate 16. Later, as the slider 7 moves, the push rod 18 will contact the bottom end of the pressure plate 16 and lift the pressure plate 16. At this time, the pull rod 20 will also slide up while keeping in contact with the side wall of the fixing rod 6.

[0022] A roller 23 is provided at a position on the bottom of the pull rod 20 close to one side of the rack rod 15 , and the roller 23 is rotatably connected to the side wall of the fixed rod 6 .

[0023] like Figure 8 As shown: The contact between the roller 23 and the pull rod 20 can avoid direct contact with the fixed rod 6 when the pull rod 20 rises and falls, thereby reducing friction.

[0024] Two transverse plates 13 are provided, and the two transverse plates 13 are symmetrically distributed front and back with respect to the fixing frame 12 .

[0025] like Figure 1 As shown: By means of the transverse plates 13 and the conveying wheels 14 located at the front and rear sides of the cutting assembly 2, the front and rear ends of the plate can be fixed at the same time when the plate is cut, so that both sides of the plate are subjected to uniform downward pressure, and the conveying force and fixing force can be prevented from failing when the plate is about to be cut.

[0026] The conveying wheels 14 are rotatably connected to the connecting pieces 24, the side walls of the connecting pieces 24 are fixedly connected to the first motors 25, the output shafts of the first motors 25 pass through the connecting pieces 24 and are fixedly connected to the conveying wheels 14, the connecting pieces 24 are slidably connected to the cross plates 13, and a fourth spring 26 is fixedly connected between the connecting pieces 24 and the inner walls of the cross plates 13.

[0027] like Figure 3 As shown: The first motor 25 drives the conveying wheel 14 to rotate and convey the plate, and the cooperation between the fourth spring 26 and the connecting member 24 enables the conveying wheel 14 to move up and down, thereby facilitating the downward fixing and conveying of plates of different thicknesses.

[0028] The driving group includes a first threaded screw 27 and a second threaded screw 28. The first threaded screw 27 is threadedly connected to the push rod 4, and the second threaded screw 28 is threadedly connected to the contact rod 5. The first threaded screw 27 and the second threaded screw 28 are both fixedly connected to the second motor 10, and the second motor 10 is fixedly connected to the body 1.

[0029] like Figure 6 and Figure 7 As shown: The first threaded screw 27 and the second threaded screw 28 are driven to rotate by the second motor 10, thereby realizing the left and right movement of the push rod 4 and the contact rod 5 respectively.

[0030] The conveying wheels 14 are all provided with a rubber layer.

[0031] As shown in the figure: the conveying wheel 14 with a rubber layer can increase friction, thereby improving the conveying effect of the plate. The rubber layer is a prior art and belongs to common knowledge, so it is not specifically described in the figure.
