Description

Technical Field

[0001] This utility model relates to a thick wood board grooving machine, belonging to the field of grooving machine technology. Background Technology

[0002] Grooving wood boards is usually done manually. Each board needs to be measured, marked, and positioned before grooving. After grooving, the board is replaced for grooving the next board. This results in high labor intensity and low processing efficiency for operators. Furthermore, due to manual measurement and processing, there are large processing errors and a high defect rate, which further reduces processing efficiency. To address this, various grooving devices have been developed within the industry. For example, Chinese utility model patent CN217967449U discloses a wood grooving device, specifically including an operating table with a baffle on one side and strip blocks connected to it via sliders. The operating table also includes a drawer, support legs below it, a vertical rod above it, a horizontal bar on the vertical rod, a large dial on the horizontal bar, a motor housing below the horizontal bar containing a large motor, a long fixed base below the motor housing connected to it via a push rod, and a fixing block below the long fixed base containing a small motor. However, for large-scale grooving operations, these grooving machines require frequent manual handling between the operating table and the placement point, resulting in a significant workload. Utility Model Content

[0003] The purpose of this invention is to provide a thick wood board grooving machine. This invention is suitable for large-scale batch grooving operations, reducing the workload of workers and improving production efficiency.

[0004] The technical solution of this utility model is as follows: A thick wood grooving machine includes a mounting frame. Multiple sliding rods are inclinedly arranged on the upper end of the mounting frame. Linear bearings are symmetrically arranged on the sliding rods. A connecting plate connects the outer sides of the linear bearings on the same side. A connecting rod is provided on the inner side of the lower end of the connecting plate. The inclined direction of the connecting rod is the same as that of the sliding rod, and a baffle is provided at its bottom end. A reciprocating mechanism is provided on the mounting frame. A moving plate is provided at the moving end of the reciprocating mechanism. The moving plate is inclined and parallel to the connecting rod. A protruding plate is provided at the upper end of the moving plate. A blade adjustment mechanism is provided on the mounting frame between the baffles. Grooving blades are symmetrically arranged at the bottom end of the blade adjustment mechanism.

[0005] The aforementioned thick wood grooving machine includes a reciprocating mechanism comprising a mounting base at the top of a mounting frame, with a screw rotatably connected between the mounting base and the mounting frame; a motor is provided at the outer end of the mounting base, and the output end of the motor is fixedly connected to the screw; a nut block is provided on the screw, and the nut block is fixedly connected to a moving plate; multiple sliders are symmetrically arranged on both sides of the screw on the mounting frame, and a first sliding guide rail is slidably connected to the slider, and the first sliding guide rail is fixedly connected to the moving plate.

[0006] The aforementioned thick wood grooving machine includes a blade adjustment mechanism comprising a second sliding guide rail mounted on a mounting frame, on which multiple blade holders are slidably connected. Each blade holder has a groove, and a blade connecting block is slidably connected within the groove. The grooving blade is located at the bottom end of the blade connecting block.

[0007] In the aforementioned thick wood grooving machine, the top of the blade connecting block is provided with a first T-shaped groove; the blade holder is provided with a second T-shaped groove located at the top of the slide groove, and an I-shaped block is connected between the second T-shaped groove and the first T-shaped groove.

[0008] The aforementioned thick wood grooving machine has multiple threaded through holes at the top of the tool holder, and tightening bolts are installed in the threaded through holes. The tightening bolts pass through the threaded through holes and abut against the second sliding guide rail.

[0009] In the aforementioned thick wood board grooving machine, the bottom end of the mounting frame is provided with multiple L-shaped rods, which are inclined and parallel to the moving plate.

[0010] In the aforementioned thick wood grooving machine, the height of the convex plate is not higher than the height of the wood board to be processed.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this invention, the position of the blade adjustment mechanism is first adjusted according to the desired grooving location. Based on the width of the wooden board, the linear bearing slides on the slide rod to adjust the spacing between the baffles to match the board width. The wooden boards are then stacked between the baffles and positioned on the upper surface of the moving plate, allowing grooving to begin. A reciprocating mechanism moves the moving plate towards the bottom in an inclined direction. The convex plate moves with the moving plate, contacting the upper end of the bottommost wooden board and pushing it against the grooving blade, thus completing the grooving. The grooved board slides off the bottom of the moving plate, at which point the convex plate is at the bottom of the stacked boards. The reciprocating mechanism then moves the moving plate in the opposite direction, separating the convex plate from the stacked boards. The falling board contacts the moving plate again. This process is repeated until all the wooden boards are grooved. Therefore, this invention achieves large-scale batch grooving operations and has the advantages of simple structure and ease of use.

[0013] 2. In this utility model, the reciprocating mechanism uses a motor to make the screw rotate in the forward or reverse direction, and the screw makes the nut block move in the forward or reverse direction along its guide. At the same time, under the cooperation of the first sliding guide rail and the slider, the reciprocating movement of the moving plate is realized.

[0014] 3. In this invention, considering different numbers and positions of slots, the number of tool holders is adjusted to match the number of slots, and the tool holders are moved on the second sliding guide rail to match the slot positions. Then, a tightening bolt is screwed into the threaded through hole, causing the tightening bolt to abut against the second sliding guide rail, thus fixing the tool holder. Considering different slot depths, after moving the blade connecting block to a suitable height within the groove, an I-shaped block of appropriate length is inserted between the second T-slot and the first T-slot, thus fixing the blade connecting block. Therefore, this invention can be adjusted according to slotting requirements, offering the advantage of high adaptability. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example: A thick wood grooving machine, configured as follows Figure 1-4 As shown, it includes mounting bracket 1, such as Figure 3As shown, the mounting frame 1 has multiple sliding rods 2 inclinedly arranged on its upper end. Linear bearings 3 are symmetrically arranged on the sliding rods 2. A connecting plate 4 connects the outer sides of the linear bearings 3 on the same side. A connecting rod 5 is provided on the inner side of the lower end of the connecting plate 4. The inclined direction of the connecting rod 5 is the same as that of the sliding rod 2, and a baffle 6 is provided at its bottom end. The gap between the baffles 6 is used to place the wooden board to be grooved. The mounting frame 1 has a reciprocating mechanism 7. The moving end of the reciprocating mechanism 7 has a moving plate 8, which is inclined and parallel to the connecting rods 5. A protruding plate 9 is provided at the upper end of the moving plate 8. The height of the protruding plate 9 is not higher than the height of the wooden board to be processed. The protruding plate 9 is used to push the bottommost wooden board to be processed towards the grooving blade 11. The mounting frame 1 has a blade adjustment mechanism 10 located between the baffles 6. Grooving blades 11 are symmetrically arranged at the bottom end of the blade adjustment mechanism 10. Multiple L-shaped rods 27 are provided at the bottom end of the mounting frame 1. The L-shaped rods 27 are inclined and parallel to the moving plate 8. After the grooving is completed, the wooden boards slide out from the front end of the movable board 8 and fall onto the L-shaped bar 27 for stacking. This prevents the wooden boards from falling to the ground and being damaged due to excessive height difference. Once a certain number have been stacked, the workers remove the wooden boards from the L-shaped bar 27.

[0022] Preferably, such as Figure 2 As shown, the reciprocating mechanism 7 includes a mounting base 12 disposed at the top of the mounting frame 1, with a screw 13 rotatably connected between the mounting base 12 and the mounting frame 1; a motor 14 is disposed at the outer end of the mounting base 12, and the output end of the motor 14 is fixedly connected to the screw 13; a nut block 15 is disposed on the screw 13, and the nut block 15 is fixedly connected to the moving plate 8; a plurality of sliders 16 are symmetrically disposed on both sides of the screw 13 on the mounting frame 1, and a first sliding guide rail 17 is slidably connected to the sliders 16, and the first sliding guide rail 17 is fixedly connected to the moving plate 8. The reciprocating mechanism 7 causes the screw 13 to rotate in the forward or reverse direction through the motor 14, and the screw 13 causes the nut block 15 to move in the forward or reverse direction along its guide; at the same time, under the cooperation of the first sliding guide rail 17 and the sliders 16, the moving plate 8 is reciprocated.

[0023] Preferably, such as Figure 3 and 4As shown, the blade adjustment mechanism 10 includes a second sliding guide rail 18 mounted on the mounting bracket 1. Multiple blade holders 19 are slidably connected to the second sliding guide rail 18. The number of blade holders 19 is adjusted according to the number of slots to be cut. In this embodiment, the number of blade holders 19 is one. Each blade holder 19 has a sliding groove 20, within which a blade connecting block 21 is slidably connected. The slotting blades 11 are located at the bottom end of the blade connecting block 21, and are arranged in a V-shape. Due to this V-shape, the reciprocating mechanism 7 causes the convex plate 9 to abut against the wooden board and move towards the slotting blades 11, resulting in strips of cut waste material, thus preventing dust generation during the slotting operation. The top of the blade connecting block 21 has a first T-shaped groove 22. The blade holder 19 has a second T-shaped groove 23 located at the top of the sliding groove 20, and an I-shaped block 24 connects the second T-shaped groove 23 and the first T-shaped groove 22. Considering different slotting depths, after moving the blade connecting block 21 to a suitable height within the slide groove 20, an I-shaped block 24 of appropriate length is inserted between the second T-slot 23 and the first T-slot 22 to fix the blade connecting block 21. The top of the tool holder 19 has three threaded through holes 25, each containing a tightening bolt 26 that passes through the threaded through holes 25 and abuts against the second sliding guide rail 18. Considering different slotting positions, the tool holder 19 is moved on the second sliding guide rail 18 to match the slotting position, and then the tightening bolt 26 is screwed into the threaded through holes 25, causing the tightening bolt 26 to abut against the second sliding guide rail 18, thus fixing the tool holder 19.

[0024] Working principle:

[0025] Before processing, adjust the number and position of the tool holders 19 according to the number and position of the slots. Then, adjust the height of the blade connecting block 21 according to the processing depth. Next, slide the linear bearing 3 on the slide rod 2 according to the width of the wooden board to adjust the spacing between the baffles 6 to match the width of the wooden board. Then, stack the wooden boards between the baffles 6 and place them on the upper surface of the moving plate 8. Then, the grooving operation can begin. The reciprocating mechanism 7 first moves the moving plate 8 to the bottom end in the inclined direction. The convex plate 9 moves with the moving plate 8 and touches the upper end of the bottom wooden board and pushes it towards the grooving blade 11, thus completing the grooving. The grooved wooden board slides from the bottom end of the moving plate 8 and falls onto the L-shaped rod 27. At this time, the convex plate 9 is located at the bottom end of the stacked wooden boards. Then, the reciprocating mechanism 7 moves the moving plate 8 in the opposite direction. The convex plate 9 separates from the stacked wooden boards, and the wooden board falls and contacts the moving plate 8. Then, repeat the above steps to groov all the wooden boards.
