Description

Technical Field

[0001] The invention relates to the technical field of cutting processing, in particular to a board cutting machine for wood processing. Background Art

[0002] Wood cutting is a commonly used processing method for wood processing, which is to cut a cylindrical tree trunk into boards along the length of the trunk. Due to the large volume of the tree trunk, the volume and floor space of the cutting equipment are also large. When using traditional cutting equipment, the peeled wood from the trunk is fixed on the equipment and the wood is moved in a straight line. The cutting saw in the working state on the equipment will cut the wood, and the cut wood will be reset to the initial position, and the feed distance of the wood toward the cutting saw will be adjusted. Then, the wood will be repeatedly pushed to move, thereby realizing the cutting of the wood into boards. When using this cutting method, only one cutting work can be realized in one movement cycle of the wood, and when adjusting the wood feed, in order to avoid contact between the wood and the cutting saw, the wood needs to be adjusted at the initial position, and the wood is in a stationary state at this time, so the adjustment work also takes up a lot of time, which leads to a serious decrease in wood cutting efficiency.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 5 As shown, a woodworking sawing machine of the present invention comprises a cutting unit and a conveying unit, wherein the conveying unit is used for conveying wood, and the cutting unit is used for cutting the wood in a conveying state; The cutting unit comprises an outer frame 1, three transmission wheels 2 and a double-toothed saw belt 3, the outer frame 1 is used to support the transmission wheel 2 and the double-toothed saw belt 3, the three transmission wheels 2 are distributed in a triangle, and the double-toothed saw belt 3 is transmission-mounted on the three transmission wheels 2, so that the shape of the double-toothed saw belt 3 is also a triangle, the bottom of the double-toothed saw belt 3 is horizontal, and cutting teeth are arranged on both the front and rear sides of the double-toothed saw belt 3; The conveying unit includes a main gear 4 and a toothed plate 5, the main gear 4 and the toothed plate 5 are on the same horizontal plane, the main gear 4 is meshed with the toothed plate 5, and the shape of the toothed plate 5 is elliptical; Among them, a guide structure is provided at the bottom of the tooth plate 5, and the guide structure is used to keep the direction of the tooth plate 5 unchanged when it moves, so that when the main gear 4 rotates, the main gear 4 provides moving power to the tooth plate 5, and makes the tooth plate 5 move around the main gear 4. The main gear 4 and the tooth plate 5 are connected by a connector, and a lifting mechanism for adjusting the height of the wood is provided on the tooth plate 5.

[0020] Specifically, the shape of the tooth plate 5 is elliptical, and its length direction remains longitudinal. The left and right sides of the tooth plate 5 are both straight lines, and the front and rear sides of the tooth plate 5 are both arc-shaped, and the arc is tangent to the straight line. Through the guiding effect of the guide structure on the tooth plate 5 and the connection between the main gear 4 and the tooth plate 5 by the connector, when the main gear 4 rotates, the main gear 4 can push the tooth plate 5 to move. When the main gear 4 is engaged with the straight side wall position of the tooth plate 5, the main gear 4 pushes the tooth plate 5 to move forward or backward in a straight line. When the main gear 4 is engaged with the arc position of the tooth plate 5, the main gear 4 can push the tooth plate 5 to move from the left side of the main gear 4 to the right side of the main gear 4, or from the main gear 4 to the right side of the main gear 4 by meshing. 4 moves from the right side to the left side of the main gear 4, so that when the main gear 4 rotates unidirectionally, the main gear 4 can drive the tooth plate 5 to perform a circular motion around the axis of the main gear 4, and the direction of the tooth plate 5 remains unchanged, and the tooth plate 5 can drive the wood to move synchronously through the lifting mechanism thereon, and the outer frame 1 can support the transmission wheel 2 and the double-toothed saw belt 3, the double-toothed saw belt 3 is arranged horizontally, and the bottom middle position of the double-toothed saw belt 3 is located above the main gear 4, so that when the tooth plate 5 moves linearly on the left or right side of the main gear 4, the tooth plate 5 can drive the wood thereon to pass through the double-toothed saw belt 3, and at this time the double-toothed saw belt 3 can cut the wood, thereby realizing the wood cutting work.

[0021] In actual use, when the double-toothed saw belt 3 cuts a board on the wood, the tooth plate 5 moves to the front or rear side of the main gear 4. At this time, the wood is separated from the double-toothed saw belt 3, and the board is taken away by an external mechanical arm or other grabbing structure, thereby preventing the board from always staying on the wood of the lifting mechanism. When the tooth plate 5 moves to the front or rear side of the main gear 4, the lifting mechanism pushes the wood up a specified distance, so that when the wood passes through the double-toothed saw belt 3 again, the double-toothed saw belt 3 can conveniently cut the wood.

[0022] By making the wood move in a circular motion around the main gear 4, the wood can be conveniently passed through the double-toothed saw belt 3 twice in one motion cycle, so that the wood can complete two board cutting operations in one motion cycle, which can greatly improve the wood cutting efficiency. At the same time, since the wood position adjustment work is completed synchronously in the wood movement cycle, the continuity of wood cutting can be guaranteed. Since the main gear 4 is used to push the tooth plate 5 to move and make the tooth plate 5 move in a circular motion around the main gear 4, the continuous unidirectional rotation of the main gear 4 can be used to achieve a circumferential continuous cutting method of the wood, which makes the structure and operation method simpler and facilitates assembly and maintenance.

[0023] More preferably, a column 23 is provided on the top of the main gear 4, a rotating plate 6 is rotatably provided on the column 23, a plug column 7 is vertically provided on the rotating plate 6, an annular groove 8 is opened on the upper surface of the tooth plate 5, the shape of the annular groove 8 is consistent with the shape of the tooth plate 5, and the bottom of the plug column 7 is slidably inserted into the annular groove 8.

[0024] Specifically, the size of the annular groove 8 is obtained by proportionally reducing the outer size of the tooth plate 5. By rotating the plate 6, the plug post 7 and the annular groove 8, the main gear 4 and the tooth plate 5 can be dynamically connected, so that when the main gear 4 and the tooth plate 5 move synchronously, they always remain in a meshing state, that is, when the main gear 4 is meshed with the straight side wall position of the tooth plate 5, the extension line of the connection line between the axis of the main gear 4 and the plug post 7 is perpendicular to the length direction of the tooth plate 5. When the main gear 4 is meshed with the arc position of the tooth plate 5, the extension line of the connection line between the axis of the main gear 4 and the plug post 7 coincides with the center of the arc position of the tooth plate 5. In this way, when the main gear 4 rotates and pushes the tooth plate 5 to move, the distance between the main gear 4 and the tooth plate 5 remains unchanged, that is, the main gear 4 and the tooth plate 5 always remain in a meshing state.

[0025] When the tooth plate 5 moves from the left side to the right side of the main gear 4, or moves from the right side to the left side of the main gear 4, the tooth plate 5 can drive the rotating plate 6 to rotate on the column 23 in the opposite direction through the plug column 7, and the column 23 can support the main gear 4.

[0026] More preferably, the guide structure includes a guide rail 9, a movable platform 10 and a slide plate 11, the movable platform 10 slides on the guide rail 9 along the longitudinal direction of the horizontal plane, the slide plate 11 slides on the movable platform 10 along the transverse direction of the horizontal plane, and the slide plate 11 is fixedly connected to the bottom of the toothed plate 5.

[0027] Specifically, when the tooth plate 5 is located on the left or right side of the main gear 4 and moves in a straight line, the tooth plate 5 can drive the moving platform 10 to slide on the guide rail 9 through the slide plate 11. When the tooth plate 5 moves from the left side of the main gear 4 to the right side of the main gear 4, or the tooth plate 5 moves from the right side of the main gear 4 to the left side of the main gear 4, since the tooth plate 5 moves around the main gear 4, the movement trajectory of the tooth plate 5 is an arc at this time, and the direction of the tooth plate 5 remains unchanged. The tooth plate 5 drives the slide plate 11 to slide on the moving platform 10. At the same time, the tooth plate 5 drives the moving platform 10 to slide on the guide rail 9 through the slide plate 11, thereby guiding the tooth plate 5 through the guide structure.

[0028] More preferably, the lifting mechanism is provided with an arc-shaped support plate 12 , the opening of the arc-shaped support plate 12 faces upward, and a plurality of vertebrae 13 are densely distributed on the inner wall of the arc-shaped support plate 12 .

[0029] Specifically, the wood is placed in the arc-shaped support plate 12, and the multiple vertebrae 13 can lift the wood while the top tip of the vertebrae 13 penetrates into the wood. In this way, the wood can be positioned and fixed by the multiple vertebrae 13 to prevent the wood from moving freely on the arc-shaped support plate 12, thereby achieving the purpose of fixing the wood on the lifting mechanism.

[0030] By adopting the structure of the arc-shaped supporting plate 12 and the plurality of cones 13, the wood can be fixed quickly and effectively, and the structure is simple and highly functional.

[0031] More preferably, the lifting mechanism includes a plurality of threaded sleeves 14 rotatably mounted on the upper surface of the toothed plate 5, each threaded sleeve 14 being screwed with a threaded rod 15, the top of the threaded rod 15 extending to the outside of the threaded sleeve 14 and being fixedly connected to the bottom of the arc-shaped support plate 12, a first worm gear 16 being provided on the outer wall of the threaded sleeve 14, a first motor 17 being fixed to the upper surface of the toothed plate 5, a first worm 18 being provided at the output end of the first motor 17, and the first worm 18 being meshingly transmission-connected with each first worm gear 16.

[0032] Specifically, multiple threaded sleeves 14 are arranged nonlinearly, which makes it convenient to improve the supporting effect of multiple threaded sleeves 14 on the arc-shaped support plate 12. The first motor 17 can drive each first worm gear 16 to rotate through the first worm 18, and the first worm gear 16 drives the threaded sleeve 14 to rotate. Since the threaded sleeve 14 is threadedly connected to the threaded rod 15, the threaded sleeve 14 can push the threaded rod 15 to move up and down, thereby pushing the arc-shaped support plate 12 and the wood on the arc-shaped support plate 12 to move in the vertical direction, so as to adjust the height position of the wood.

[0033] Preferably, the outer frame 1 is provided with a second motor 19, the lower output end of the second motor 19 is provided with a second worm 20, the second worm 20 is meshed with a second worm wheel 21, the second worm wheel 21 is transmission-connected with a transmission wheel 2 on the outer frame 1, a transmission gear 22 is provided at the bottom of the second worm 20, a tooth groove is provided on the outer wall of the column 23, and the transmission gear 22 meshes with the teeth in the tooth groove; The top of the column 23 is rotatably mounted on the outer frame 1 .

[0034] Specifically, the outer frame 1 can support the main gear 4 through the column 23, the second motor 19 can drive the second worm wheel 21 and the transmission gear 22 to rotate through the second worm 20, the second worm wheel 21 drives the transmission wheel 2 to rotate, thereby driving the double-tooth saw belt 3 to rotate, and the transmission gear 22 drives the column 23 and the main gear 4 to rotate through the tooth grooves on the column 23, thereby providing power for the double-tooth saw belt 3 and the main gear 4 synchronously.

[0035] A connecting plate is provided on each transmission wheel 2 on the outer frame 1, and the transmission wheel 2 is arranged on the outer frame 1 through the connecting plate. The top of the column 23 is rotatably mounted on the bottom of the connecting plate on a transmission wheel 2, so that the column 23 is rotatably mounted on the outer frame 1.

[0036] More preferably, the column 23 is hollow inside, and a process groove is provided at the bottom of the main gear 4.

[0037] Specifically, in order to reduce the weight of the column 23 and the main gear 4, a hollow portion may be provided inside the column 23 and a process groove may be provided at the bottom of the main gear 4, thereby reducing the demand for the support strength of the outer frame 1, reducing the strength of the equipment, and facilitating processing.

[0038] More preferably, it further comprises a shield 24 , which is sleeved on the outside of the column 23 and the transmission gear 22 , and shields the top of the main gear 4 .

[0039] Specifically, the shield 24 is fixed on a connecting plate on a transmission wheel 2, and the shield 24 can shield and protect the main gear 4, the transmission gear 22 and the column 23, thereby preventing sawdust generated by wood cutting from affecting the transmission work of the equipment.
