Description

Technical Field

[0001] This invention relates to the technical field of cutting equipment, and in particular to a board cutting device for the production of multi-layer solid wood composite flooring. Background Technology

[0002] Multi-layer composite flooring uses multi-layer plywood as the base material, with a surface layer of hardwood veneer or sliced ​​veneer, all bonded together with glue and hot pressing. The number of plywood layers in the base layer is always an odd number, usually seven or nine, and the surface layer is a hardwood veneer. During processing, long planks need to be cut into planks of a specified width for subsequent splicing. The traditional cutting method involves first measuring and marking the specified dimensions on the long plank with calipers, then placing the marked plank at the cutting blade position and repeatedly cutting at each marked location. This method is cumbersome, requiring frequent and repetitive marking and cutting, consuming significant manpower, and resulting in slow cutting speed and low work efficiency.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0032] like Figures 1 to 5As shown, the board cutting device for producing multi-layer solid wood composite flooring of the present invention includes a cutting part located on the upper side and a conveying part located on the lower side. The conveying part includes a rotating drum 1 and a support shaft 2. The axis of the support shaft 2 is horizontal. The rotating drum 1 is rotatably mounted on the support shaft 2 and is supported by the support shaft 2. Multiple sets of annular groove plate units are arranged sequentially along the axis of the support shaft 2 on the outer wall of the support shaft 2 inside the rotating drum 1. Each set of annular groove plate units consists of two annular groove plates 3. The annular groove plates 3 are fitted and fixed on the outer wall of the support shaft 2, and the two annular groove plates 3 are oriented opposite each other. The top of the annular groove plates 3 is horizontal. Multiple sliding columns 4 are slidably clamped in each set of annular groove plates 3. A right-angle clamp 5 is provided on the sliding column 4. The outer end of the right-angle clamp 5 passes through the rotating drum 1 and slides out to the outside of the rotating drum 1. The right angle position of the right-angle clamp 5 is located on the outside of the rotating drum 1.

[0033] The cutting section consists of multiple equally spaced cutting blades 6.

[0034] Specifically, multiple right-angle clamps 5 on the outside of the rotating drum 1 are arranged in a ring to form multiple groups. Each group of right-angle clamps 5 consists of multiple right-angle clamps 5, and each group of right-angle clamps 5 is arranged along the axis of the support shaft 2. Since the right-angle position of the right-angle clamps 5 is located on the outside of the rotating drum 1, the right-angle position of the right-angle clamps 5 and the outer wall of the rotating drum 1 form a U-shape. The U-shaped opening on one side of the rotating drum 1 faces downward, and the U-shaped opening on the other side of the rotating drum 1 faces upward. When feeding, the long plate is fed from the side of the rotating drum 1 with the U-shaped opening facing upward, and the cut plate is unloaded from the side of the rotating drum 1 with the U-shaped opening facing downward.

[0035] During operation, the long plate is placed on multiple right-angle clamps 5 on the outside of the rotating drum 1. The rotating drum 1 rotates, and the right-angle clamps 5 drive the sliding column 4 to slide between two annular groove plates 3. Since the top of the annular groove plates 3 is horizontal, when the sliding column 4 slides to this position, the distance between the sliding column 4 and the inner wall of the rotating drum 1 increases. At this time, the sliding column 4 pulls the right-angle clamps 5 to slide on the rotating drum 1. The right-angle position of the right-angle clamps 5 approaches the outer wall of the rotating drum 1 and automatically clamps and locks the long plate. When the long plate rotates to the top of the rotating drum 1... When in position, the cutting blades 6 of the cutting section cut the long plate between two adjacent right-angle clamping plates 5. Multiple cutting blades 6 cut simultaneously, so that the long plate is cut into multiple plates at one time. The rotating drum 1 continues to rotate, and the sliding column 4 moves towards the top left side of the annular groove plate 3. At this time, the right-angle position of the right-angle clamping plate 5 gradually moves away from the outer wall of the rotating drum 1. The right-angle clamping plate 5 stops clamping the cut plates, and the plates slide naturally from the outer wall of the rotating drum 1 onto the external conveyor belt, thus completing the automatic cutting of the plates.

[0036] The rotating drum 1 rotates continuously, thus enabling continuous cutting of long plates.

[0037] By employing a rotating continuous conveyor, automatic clamping, and multi-segment cutting method to automatically cut the board, the automatic processing of the board can be realized, avoiding the tedious operations of marking and positioning and repeated cutting, simplifying the board processing method, saving manpower, and at the same time, the board cutting can be completed in multiple segments at one time, which effectively improves work efficiency.

[0038] Preferred, such as Figure 5 As shown, the right-angle clamp 5 is composed of a first sub-plate 7, a second sub-plate 8 and a push plate 9. The first sub-plate 7 is fixedly connected to the sliding column 4, the second sub-plate 8 is slidably connected to the first sub-plate 7, and the second sub-plate 8 and the first sub-plate 7 are elastically connected by a first leaf spring 10. The second sub-plate 8 passes through the rotating cylinder 1 and slides relative to it. The push plate 9 is set on the end of the second sub-plate 8 on the outside of the rotating cylinder 1.

[0039] Specifically, by adopting a combination method, processing, maintenance, and replacement can be facilitated. At the same time, by making the first auxiliary plate 7 and the second auxiliary plate 8 elastically connected by the first leaf spring 10, when the sliding column 4 moves in the horizontal part at the top of the annular groove plate 3, the first auxiliary plate 7 and the second auxiliary plate 8 can provide buffer space for the push plate 9. When the push plate 9 clamps the plate, the sliding column 4 can still pull the first auxiliary plate 7 to slide on the second auxiliary plate 8. At this time, the first leaf spring 10 undergoes elastic deformation, thereby forming a working state in which the push plate 9 can clamp the plate for a specified time. This avoids the situation where the sliding column 4 and the push plate 9 are rigidly connected. Only when the sliding column 4 moves to the farthest distance from the inner wall of the rotating drum 1 can the push plate 9 contact the plate. This clamping state can only last for a moment and cannot provide enough time for cutting.

[0040] By adopting the structural method of supplying the first auxiliary plate 7, the second auxiliary plate 8 and the first leaf spring 10, it is also possible to clamp plates of different thicknesses.

[0041] Preferred, such as Figure 6 As shown, the side of the push plate 9 facing the outer wall of the rotating cylinder 1 is arranged from top to bottom as a clamping surface 11, an inclined surface 12 and a limiting surface 13. The clamping surface 11 and the limiting surface 13 are both perpendicular to the second auxiliary plate 8. The outer end of the second auxiliary plate 8 is inclined and slidably mounted on the inclined surface 12. The push plate 9 and the second auxiliary plate 8 are elastically connected by a second leaf spring 14.

[0042] Specifically, the second leaf spring 14 provides elastic thrust to the push plate 9, and the limiting surface 13 blocks and positions the second auxiliary plate 8. When the second auxiliary plate 8 pulls the push plate 9 toward the outer wall of the rotating cylinder 1, the clamping surface 11 on the push plate 9 contacts the plate. At this time, due to the sliding connection between the second auxiliary plate 8 and the inclined surface 12, the force exerted by the second auxiliary plate 8 on the push plate 9 is tilted, thereby causing the plate to push the push plate 9 downward on the second auxiliary plate 8 in the opposite direction. The second leaf spring 14 undergoes elastic deformation, thereby causing the clamping surface 11 to generate a squeezing force toward the outer wall of the rotating cylinder 1 and a frictional force toward the second auxiliary plate 8 on the plate, thereby improving the fixing strength of the plate.

[0043] Preferred, such as Figure 6 As shown, the push plate 9 has a notch 15 in the middle. A support sleeve 16 is provided on the end face of the second sub-plate 8 inside the notch 15. The support sleeve 16 extends to the outside of the push plate 9. A slide rod 17 is provided on the support sleeve 16. One end of the slide rod 17 passes through the support sleeve 16 and slides relative to it. The slide rod 17 and the support sleeve 16 are elastically connected by a third leaf spring 18. The slide rod 17 is perpendicular to the second sub-plate 8. An arc plate 19 is inclinedly hinged to the other end of the slide rod 17. A buckle plate 20 is inclinedly hinged to the outer end of the arc plate 19. The end of the buckle plate 20 is hinged to the outer end face of the push plate 9.

[0044] Specifically, in the initial state, the buckle plate 20 is tilted outward on the push plate 9. At this time, the buckle plate 20 can act as a guide to guide the board, making it easier for the board to enter smoothly between the second sub-plate 8 and the push plate 9. When the push plate 9 slides relative to the second sub-plate 8, the push plate 9 can pull the buckle plate 20 to move. At this time, the slide rod 17 and the arc plate 19 provide support and guidance force for the buckle plate 20. The buckle plate 20 rotates from the outward tilting state to between the second sub-plate 8 and the push plate 9, and the buckle plate 20 seals the top of the board, thereby fixing the board from multiple directions.

[0045] When the height of the board on the second sub-board 8 is small, the buckle 20 tilts downward and overlaps the top of the board. At this time, the continuously moving push plate 9 can push the slide rod 17 to slide downward on the support sleeve 16 through the buckle 20 and the arc plate 19. The third leaf spring 18 undergoes elastic deformation, thereby providing sufficient room for the buckle 20 to move and increasing the range of action of the buckle 20.

[0046] Preferred, such as Figure 3 As shown, multiple rows of baffles 21 are arranged in a ring on the outer wall of the rotating cylinder 1. Each row of baffles 21 is along the axial direction of the rotating cylinder 1, and each row of baffles 21 consists of multiple baffles 21. The surface of the baffles 21 is facing down towards the push plate 9.

[0047] Each row of baffles 21 has a process port 22 on the outer wall of the rotating cylinder 1 between two adjacent baffles 21.

[0048] Specifically, the outer end of the baffle 21 extends outward, and the plate is held between the baffle 21 and the push plate 9. After the plate is cut, it can slide outward along the baffle 21, thereby guiding the plate through the baffle 21 and preventing it from sliding onto the adjacent slide bar 17 and getting stuck there. The baffle 21 blocks the adjacent slide bar 17. By opening the process port 22, space can be provided for the cutting work of the cutting blade 6, and the cutting blade 6 can be prevented from damaging the outer wall of the rotating drum 1.

[0049] Preferred, such as Figure 7As shown, the cutting part also includes two substrates 23 arranged opposite to each other. A swing disk 24 is rotatably provided at the bottom of the substrate 23. A square column 25 is fixed between the two swing disks 24. A plurality of extension arms 26 are provided on the square column 25. The cutting blade 6 is rotatably mounted on the extension arms 26.

[0050] A fixing plate 27 is fixed on one of the base plates 23, and a first motor 28 is fixed on the fixing plate 27. The output end of the first motor 28 is provided with a connecting rod 29, and the outer end of the connecting rod 29 is provided with a push column 30. The push column 30 is eccentric to the output end of the first motor 28. A sliding groove is provided on the side wall of the swing disk 24 along its radial direction, and the outer end of the push column 30 is slidably installed in the sliding groove.

[0051] Specifically, the first motor 28 drives the push column 30 to rotate eccentrically through the connecting rod 29. The push column 30 pushes the swing disk 24 to swing back and forth through the slide groove. The swing disk 24 drives the square column 25, the extension arm 26 and the cutting blade 6 to swing back and forth, so that the cutting blade 6 moves closer to the plate to cut it or moves away from the rotating drum 1 so that the rotating drum 1 can transport the plate normally.

[0052] Preferred, such as Figure 7 As shown, it also includes a second motor 31, which is mounted on a swing disk 24. The output end of the second motor 31 is provided with a first worm gear 32, which is rotatably mounted between the two swing disks 24. The first worm gear 32 passes through the extension arm 26 and slides relative to it. Multiple first worm wheels 33 are meshed on the first worm gear 32. A second worm gear 34 is driven on the first worm wheel 33. The second worm gear 34 is rotatably mounted on the extension arm 26. A second worm wheel 35 is provided at the outer end of the second worm gear 34, and the second worm wheel 35 is drivenly connected to the cutting blade 6.

[0053] Specifically, the second motor 31 can drive the first worm 32 to rotate, and the first worm 32 can drive multiple cutting blades 6 to rotate synchronously through the first worm wheel 33, the second worm 34 and the second worm wheel 35, thereby providing power to the cutting blades 6 at any position.

[0054] Preferred, such as Figure 8 As shown, it also includes a translation plate 36, which is located at the bottom of the extension arm 26. The end of the translation plate 36 is slidably mounted on the side wall of the swing disk 24, and the sliding direction of the translation plate 36 is parallel to the length direction of the extension arm 26. Multiple guide grooves are provided on the translation plate 36. The guide grooves are inclined, and an adjustment column 37 is slidably provided in the guide groove. The adjustment column 37 is fixed on the extension arm 26. A cylinder 38 is fixed on the swing disk 24, and the output end of the cylinder 38 is connected to the translation plate 36.

[0055] The extension arm 26 slides on the square column 25. When the translation plate 36 moves, it can push multiple adjustment columns 37 to move synchronously through multiple guide grooves in an inclined state. The distance between two adjacent adjustment columns 37 is always equal, thereby achieving the purpose of equidistant movement of multiple adjustment columns 37.

[0056] Specifically, the extension lines of multiple adjustment columns 37 intersect at a point. The cylinder 38 can push the translation plate 36 to move, thereby causing the multiple adjustment columns 37 to move synchronously and equidistantly. At this time, the multiple extension arms 26 move synchronously and equidistantly, thereby adjusting the position of the multiple cutting blades 6. The distance between the multiple cutting blades 6 is always kept equal, thereby synchronously adjusting the width of the multiple cut plates.

[0057] Preferred, such as Figure 2 As shown, a third motor 39 is fixed on the outer wall of the support shaft 2. The output end of the third motor 39 drives a transmission wheel 40. A transmission ring 41 is provided on the end face of the rotating drum 1. The transmission wheel 40 and the transmission ring 41 are connected in a transmission manner.

[0058] Specifically, the third motor 39 drives the rotating drum 1 to rotate through the transmission wheel 40 and the transmission ring 41.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
