A plate blank cutting device for plywood production

Abstract

This utility model provides a plywood blank cutting device for plywood production, belonging to the technical field of production equipment. It includes a conveyor belt, a straight pressure plate, and a cutting module. An arc-shaped pressure plate is located below the straight pressure plate. The first end of the arc-shaped pressure plate is connected to the bottom of the cutting module, and the second end extends towards the material-feeding end of the conveyor belt and upwards to slide in contact with the straight pressure plate. By setting the arc-shaped pressure plate below the straight pressure plate, as the straight pressure plate moves downwards, the arc-shaped pressure plate is pushed downwards until it is flattened. During this process, the arc-shaped pressure plate gradually presses the plywood blank from the feeding end of the conveyor belt towards the material-feeding end. Under the elastic pressure of the arc-shaped pressure plate, the wrinkles of the plywood blank are gradually unfolded towards the material-feeding direction, fully extending the plywood blank and avoiding wrinkle overlap caused by direct pressing. The fully extended plywood blank also improves the utilization rate of the plywood.

Description

Technical Field

[0001] This utility model belongs to the technical field of plywood production equipment, specifically referring to a plywood blank cutting device for plywood production. Background Technology

[0002] Plywood is a three- or multi-layer board made by rotary cutting logs into veneer veneers and then pressing them together with adhesive. It usually uses an odd number of veneer layers, with the fiber directions of adjacent veneers interlaced perpendicularly to enhance its structural strength and stability. Common plywood types include three-ply, five-ply, and seven-ply plywood, which have an odd number of layers.

[0003] After the logs are rotary-cut into veneer chips, they are arranged and combined in a reasonable way to form a board blank. Then, they are cut according to the required size to facilitate subsequent pressing, trimming and other work. After the boards are arranged to form a board blank, the multiple layers of veneer are relatively loose, so the board blank needs to be pre-pressed to facilitate precise cutting.

[0004] Currently, flat pressure plates are used for pre-pressing slabs. However, slabs have wrinkles. If they are pressed directly, the wrinkles cannot be fully stretched, causing them to overlap and form protrusions during pressing. This reduces the flatness of the slab surface and increases the workload of subsequent slab repair. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a board blank cutting device for plywood production, which at least partially solves the above problems.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a board blank cutting device for plywood production, including a conveyor belt and a straight pressure plate located above the conveyor belt, wherein the straight pressure plate is configured to be able to reciprocate in the vertical direction; The cutting module is located on the side of the straight pressure plate near the feeding end of the conveyor belt, and the cutting module is configured to be able to reciprocate in the vertical direction; The straight pressure plate is provided below an arc-shaped pressure plate. The first end of the arc-shaped pressure plate is connected to the bottom of the cutting module, and the second end of the arc-shaped pressure plate extends toward the material receiving end of the conveyor belt and extends upward to slide into contact with the straight pressure plate. When the second end of the arc-shaped pressure plate is pushed downward, the arc-shaped pressure plate can gradually press the blank from the feeding end of the conveyor belt toward the material receiving end.

[0007] Furthermore, the cutting module is movably connected to the straight pressure plate.

[0008] Furthermore, the straight pressure plate is provided with a guide post and a connecting arm on the side near the cutting module. The guide post is fixed on the straight pressure plate and is arranged parallel to the moving direction of the straight pressure plate. The connecting arm is slidably connected to the guide post. The cutting module is connected to the connecting arm, and the cutting module and the arc-shaped pressure plate can slide relative to the straight pressure plate in the vertical direction.

[0009] Furthermore, the guide post is equipped with a spring. When the connecting arm and the straight pressure plate move away from each other, the spring applies elastic pressure to the connecting arm, causing the cutting module to press the blank tightly.

[0010] Furthermore, a guide roller is provided on one side of the straight pressure plate near the second end of the arc-shaped pressure plate. The guide roller is arranged parallel to the width direction of the arc-shaped pressure plate, and the bottom of the guide roller is flush with the bottom surface of the straight pressure plate.

[0011] Furthermore, the first end of the arc-shaped pressure plate is provided with a connecting part, and the arc-shaped pressure plate is connected to the cutting module through the connecting part.

[0012] Furthermore, the cutting module includes a mounting frame, a cutting hydraulic cylinder, and a cutting blade. The cutting hydraulic cylinder is fixed on the mounting frame, and the telescopic end of the cutting hydraulic cylinder faces vertically toward the conveyor belt. The cutting blade is arranged perpendicular to the conveying direction of the conveyor belt, and the cutting blade is connected to the telescopic end of the cutting hydraulic cylinder.

[0013] Furthermore, a cutting tray is provided at one end of the conveyor belt near the cutting module. The cutting tray is located directly below the cutting blade, and the cutting tray is provided with a cutting edge corresponding to the cutting blade.

[0014] Furthermore, a knife-edge pressure plate is provided on the bottom side of the mounting bracket away from the arc-shaped pressure plate.

[0015] Furthermore, a support frame is connected to the conveyor belt, the support frame is located above the straight pressure plate, and a pressure plate hydraulic cylinder is fixed on the support frame. The extension and retraction direction of the pressure plate hydraulic cylinder is parallel to the movement direction of the straight pressure plate. The extension and retraction end of the pressure plate hydraulic cylinder is connected to the straight pressure plate, and the straight pressure plate is driven to reciprocate in the vertical direction by the pressure plate hydraulic cylinder.

[0016] The beneficial effects of this utility model by adopting the above structure are as follows: 1. By setting an arc-shaped pressure plate below the straight pressure plate, as the straight pressure plate moves downward, the arc-shaped pressure plate is pushed downward until it is flattened. During this process, the arc-shaped pressure plate gradually presses the slab from the feeding end of the conveyor belt to the receiving end. Under the elastic pressure of the arc-shaped pressure plate, the folds of the slab are gradually unfolded towards the receiving direction, which fully extends the slab and avoids the overlap of folds caused by direct pressing. The fully extended slab can improve the utilization rate of the board.

[0017] 2. By setting guide posts and connecting arms on the straight pressure plate, the cutting module is connected to the straight pressure plate through the guide posts and connecting arms and is pulled and moved by the straight pressure plate. It can also realize the relative movement between the straight pressure plate and the cutting module, without the need to set a separate drive mechanism for the cutting module, thus reducing the size of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1 and Figure 2 As shown, this utility model proposes a plywood blank cutting device, including a conveyor belt 1, a straight pressure plate 2 and a cutting module 3. The straight pressure plate 2 is located directly above the conveyor belt 1, and the width of the straight pressure plate 2 is smaller than the width of the conveyor belt 1 to avoid interference from the supports on both sides of the conveyor belt 1 on the movement of the straight pressure plate 2. The straight pressure plate 2 moves downward and approaches the conveyor belt 1 to press the blank on the conveyor belt 1.

[0024] The cutting module 3 is located on the side of the straight pressure plate 2 near the feeding end of the conveyor belt 1. The cutting module 3 is configured to be able to move back and forth in the vertical direction. The cutting module 3 moves downward and presses on the blank, and then cuts the blank.

[0025] Below the straight pressure plate 2, there is an arc-shaped pressure plate 4. The first end of the arc-shaped pressure plate 4 is connected to the bottom of the cutting module 3, and the second end of the arc-shaped pressure plate 4 extends towards the material receiving end of the conveyor belt 1 and upwards to slide into contact with the straight pressure plate 2. When the second end of the arc-shaped pressure plate 4 is pushed downwards, the arc-shaped pressure plate 4 can gradually press the blank from the feeding end of the conveyor belt 1 towards the material receiving end (e.g., ...). Figure 6 (As shown).

[0026] Thus, the cutting module 3 first moves downward and presses onto the blank. At this time, the first end of the arc-shaped pressure plate 4 connected to the bottom of the cutting module 3 also presses onto the blank. As the straight pressure plate 2 moves downward, the second end of the arc-shaped pressure plate 4 is pushed downward until the arc-shaped pressure plate 4 is flattened (as shown). Figure 7As shown), during this process, the arc-shaped pressure plate 4 gradually presses the slab from the feeding end of the conveyor belt 1 to the receiving end, and under the elastic pressure of the arc-shaped pressure plate 4, the folds of the slab are gradually unfolded towards the receiving direction, which fully extends the slab, avoids the overlap of folds caused by direct pressing, and the fully extended slab can improve the utilization rate of the board. After the arc-shaped pressure plate 4 is flattened and held for a certain period of time, the veneer and glue are fully bonded and the blank is shaped. Then the cutting module 3 cuts the blank. After the cutting is completed, the straight pressure plate 2, the cutting module 3, and the arc-shaped pressure plate 4 move upward and separate from the blank. The conveyor belt 1 conveys the blank in the feeding direction.

[0027] In an optional embodiment, the arc-shaped pressure plate 4 is made of spring steel, which gives the arc-shaped pressure plate 4 good elasticity. After being flattened multiple times, it can still elastically recover to an arc shape, giving the arc-shaped pressure plate 4 a long service life.

[0028] In a specific embodiment, a support frame 11 is connected to the conveyor belt 1. The support frame 11 is located above the straight pressure plate 2, and a pressure plate hydraulic cylinder 12 is fixed on the support frame 11. The extension and retraction direction of the pressure plate hydraulic cylinder 12 is parallel to the movement direction of the straight pressure plate 2 (that is, the extension and retraction direction of the pressure plate hydraulic cylinder 12 is consistent with the movement direction of the straight pressure plate 2). The extension and retraction end of the pressure plate hydraulic cylinder 12 is connected to the straight pressure plate 2. The pressure plate hydraulic cylinder 12 is connected to an external hydraulic station, and the straight pressure plate 2 is driven to reciprocate in the vertical direction through the pressure plate hydraulic cylinder 12.

[0029] Combination Figure 2 As shown, the cutting module 3 is movably connected to the straight pressure plate 2, and the straight pressure plate 2 drives the cutting module 3 to move up and down, and the straight pressure plate 2 and the cutting module 3 can slide relative to each other in the vertical direction; When the straight pressure plate 2 moves downward, the cutting module 3 moves downward synchronously. The bottom of the cutting module 3 presses on the blank first. At this time, with the support of the conveyor belt 1, the cutting module 3 stops moving downward, while the straight pressure plate 2 can continue to move downward until the arc-shaped pressure plate 4 is flattened. When the straight pressure plate 2 moves upward, the cutting module 3 can be dragged upward by the straight pressure plate 2.

[0030] In a specific embodiment, the straight pressure plate 2 is provided with a guide post 5 and a connecting arm 51 on the side near the cutting module 3. The guide post 5 is fixed on the straight pressure plate 2 and is arranged parallel to the moving direction of the straight pressure plate 2. The connecting arm 51 is slidably connected to the guide post 5 and can slide up and down along the guide post 5. The cutting module 3 is connected to the connecting arm 51. Correspondingly, the cutting module 3 and the arc-shaped pressure plate 4 can also slide up and down along the guide post 5.

[0031] Thus, when the straight pressure plate 2 moves downward, the bottom of the cutting module 3 and the arc-shaped pressure plate 4 move downward synchronously. The bottom of the cutting module 3 and the arc-shaped pressure plate 4 press on the blank first. At this time, under the support of the conveyor belt 1, the cutting module 3 stops moving downward, while the straight pressure plate 2 can continue to move downward. During this process, the connecting arm 51 moves away from the straight pressure plate 2, and the connecting arm 51 slides along the guide post 5 to maintain the connection between the straight pressure plate 2 and the cutting module 3. When the straight pressure plate 2 moves upward, the connecting arm 51 approaches the straight pressure plate 2 until the connecting arm 51 contacts the straight pressure plate 2. At this time, the straight pressure plate 2 continues to move upward, pulling the cutting module 3 and the arc-shaped pressure plate 4 upward, so that they are separated from the blank.

[0032] Furthermore, a spring 52 is provided on the guide post 5. When the connecting arm 51 and the straight pressure plate 2 move away from each other, the spring 52 applies elastic pressure to the connecting arm 51, so that the cutting module 3 presses the blank.

[0033] Thus, when the straight pressure plate 2 moves downward to press the blank, the spring 52 is compressed, thereby applying elastic pressure to the connecting arm 51, so that the bottom of the cutting module 3 presses the blank (that is, presses the cutting part of the blank), so that the blank remains stable during the cutting process.

[0034] Combination Figure 2 and Figure 4 As shown, a guide roller 21 is provided on one side of the straight pressure plate 2 near the second end of the arc-shaped pressure plate 4. The guide roller 21 is arranged parallel to the width direction of the arc-shaped pressure plate 4. The second end of the arc-shaped pressure plate 4 is in sliding contact with the guide roller 21. When the arc-shaped pressure plate 4 is pressed down or deformed due to elastic recovery, the second end of the arc-shaped pressure plate 4 will move in the horizontal direction. At this time, since the guide roller 21 is in contact with the second end of the arc-shaped pressure plate 4, the guide roller 21 can rotate when the second end of the arc-shaped pressure plate 4 moves, which changes the sliding friction into rolling friction and reduces wear.

[0035] Furthermore, the bottom of the guide roller 21 is flush with the bottom surface of the straight pressure plate 2, so the guide roller 21 will not interfere with the movement of the straight pressure plate 2, allowing the straight pressure plate 2 to fully fit with the arc-shaped pressure plate 4 and completely flatten the arc-shaped pressure plate 4 on the conveyor belt 1.

[0036] Combination Figure 3 As shown, the first end of the arc-shaped pressure plate 4 is provided with a connecting part 41. The connecting part 41 is located above the first end of the arc-shaped pressure plate 4. When the arc-shaped pressure plate 4 is connected to the cutting module 3 through the connecting part 41, the connection will not protrude from the bottom surface of the arc-shaped pressure plate 4, so as to avoid the connection protrusion affecting the blank.

[0037] Combination Figure 2As shown, the cutting module 3 includes a mounting frame 31, a cutting hydraulic cylinder 32, and a cutting blade 33. The mounting frame 31 is fixed on the connecting arm 51, the cutting hydraulic cylinder 32 is fixed on the mounting frame 31, and the telescopic end of the cutting hydraulic cylinder 32 is vertically facing the conveyor belt 1. The cutting blade 33 is arranged perpendicular to the conveying direction of the conveyor belt 1, and the cutting blade 33 is connected to the telescopic end of the cutting hydraulic cylinder 32. The cutting hydraulic cylinder 32 drives the cutting blade 33 to move downward to cut the slab.

[0038] When the slab is not being cut, the cutting blade 33 is completely retracted within the mounting bracket 31 to avoid interfering with the downward movement of the curved pressure plate 4.

[0039] In a specific embodiment, the first end of the arc-shaped pressure plate 4 is connected to the bottom of the mounting bracket 31, and the bottom surface of the first end of the arc-shaped pressure plate 4 is flush with the bottom of the mounting bracket 31 to avoid a height difference when pressing the plate.

[0040] Combination Figure 1 and Figure 5 As shown, a cutting tray 34 is provided at one end of the conveyor belt 1 near the cutting module 3. The cutting tray 34 is located directly below the cutting blade 33. The cutting tray 34 is provided with a cutting blade 341 corresponding to the cutting blade 33. During the process of the cutting blade 33 moving downward to cut the blank, the cutting tray 34 can support both sides of the cutting area, improving the stability of the blank cutting point. The cutting blade 341 provides cutting space for the cutting blade 33. During cutting, the cutting blade 341 moves downward and passes through the cutting blade 341 to complete the cutting of the blank.

[0041] Furthermore, a blade pressure plate 311 is provided on the bottom side of the mounting bracket 31 away from the arc-shaped pressure plate 4. The blade pressure plate 311 cooperates with the cutting support plate 34 to press and fix the cutting part of the blank, so that the blank remains stable during cutting and the cutting accuracy is improved.

[0042] The working principle of this utility model is as follows: The layout line transports the arranged slab blanks to the conveyor belt 1, and the conveyor belt 1 takes over the transport until the area of ​​the slab blank to be cut is transported to below the cutting module 3. Then the conveyor belt 1 stops transporting, and the hydraulic cylinder 12 of the pressure plate drives the straight pressure plate 2 to move downward. During the initial movement, the straight pressure plate 2, the cutting module 3, and the arc-shaped pressure plate 4 move downward synchronously. When the bottom of the cutting module 3 and the arc-shaped pressure plate 4 press on the slab blank, the cutting module 3 and the arc-shaped pressure plate 4 stop moving downward under the support of the conveyor belt 1, while the straight pressure plate 2 continues to move downward. As the straight pressure plate 2 moves downward, the second end of the arc-shaped pressure plate 4 is pushed downward until the arc-shaped pressure plate 4 is flattened (e.g., Figure 7As shown), during this process, the arc-shaped pressure plate 4 gradually presses the slab from the feeding end of the conveyor belt 1 to the receiving end, and under the elastic pressure of the arc-shaped pressure plate 4, the folds of the slab are gradually unfolded towards the receiving direction, which fully extends the slab, avoids the overlap of folds caused by direct pressing, and the fully extended slab can improve the utilization rate of the board. After the arc-shaped pressure plate 4 is flattened and held for a certain period of time, the veneer and glue are fully bonded and the blank is shaped. Then, the cutting hydraulic cylinder 32 drives the cutting blade 33 to move downward to cut the blank. After the cutting is completed, the cutting blade 33 retracts into the mounting bracket 31. The hydraulic cylinder 12 drives the straight pressure plate 2 to move upward, and the connecting arm 51 approaches the straight pressure plate 2 until the connecting arm 51 contacts the straight pressure plate 2. At this time, the straight pressure plate 2 continues to move upward, pulling the cutting module 3 and the arc-shaped pressure plate 4 upward, so that they are separated from the blank. The conveyor belt 1 conveys the blank in the feeding direction.

[0043] In summary, by setting an arc-shaped pressure plate 4 below the straight pressure plate 2, as the straight pressure plate 2 moves downward, the arc-shaped pressure plate 4 is pushed downward until it is flattened (e.g., ...). Figure 7 As shown), during this process, the arc-shaped pressure plate 4 gradually presses the slab from the feeding end of the conveyor belt 1 to the receiving end. Under the elastic pressure of the arc-shaped pressure plate 4, the folds of the slab are gradually unfolded towards the receiving direction, which fully extends the slab and avoids the overlap of folds caused by direct pressing. The fully extended slab can improve the utilization rate of the board.

[0044] By setting guide posts 5 and connecting arms 51 on the straight pressure plate 2, the cutting module 3 is connected to the straight pressure plate 2 through the guide posts 5 and connecting arms 51, and is pulled and moved by the straight pressure plate 2. It can realize the relative movement of the straight pressure plate 2 and the cutting module 3, without the need to set a separate drive mechanism for the cutting module 3, thus reducing the size of the equipment.

[0046] The present invention and its embodiments have been described above.
