Description

Technical Field

[0001] The invention relates to the technical field of building decoration engineering, in particular to a heat-insulating variable floor for building decoration and a turning-over processing method. Background Art

[0002] In the decoration of buildings, the insulation floor is used to isolate the moisture from the ground and protect the floor. It can also be used to insulate the ground to maintain a constant temperature in the room (such as winter heating and summer insulation in shopping malls) and reduce air conditioning energy consumption. It usually includes a keel laid on the ground, a floor laid on the keel, and an insulation layer laid between the keel and the floor or between the ground and the floor. The compressive strength of the insulation layer must match the floor load. The insulation layer is located under the keel and needs to bear the load of the keel and the floor. Although the compressive strength (150-300kPa) of conventional insulation materials (such as XPS extruded board) meets the no-load requirements, creep under long-term load will cause support failure; if the insulation layer is located between the keel and the floor, it will occupy the installation space of the bite structure and cause bite interference.

[0003] In existing floor installations, the baseboard is laid directly on the keel without physical connection. The connection strength depends on the material's own properties (such as wood nail holding power and adhesive durability). These methods do not form a geometric interlocking bite structure. Without a bite structure, the static friction between the baseboard and the keel is the only anti-slip force. When people walk quickly or furniture is dragged, the horizontal force will cause the baseboard to slip laterally. When the baseboard is subjected to concentrated loads (such as local pressure on furniture legs > 150kg), the lack of a bite structure will result in the load being unable to be effectively dispersed to the keel, which may cause local crushing of the baseboard or unilateral overload fracture of the keel.

[0004] After the floor is laid, it needs to rely on a flat base to disperse the load. If the base is uneven, the floor will be partially suspended or stress concentrated. Excessive ups and downs in the ground may affect the locking strength between the base plates. Traditional screw-type adjustment feet (such as metal bolts + nylon pads) have uneven force on the adjustment structure. When the load exceeds the design threshold, the adjustment screw may bend and deform. The dynamic load generated by people walking or furniture moving will cause the adjustment structure to repeatedly bear shear force and tension. Metal parts (such as steel screws) are prone to fatigue fracture failure, and plastic adjustment parts (such as ABS materials) may lose their adjustment function due to creep deformation.

[0005] At the same time, the interlocking structure between the substrate and the keel brings difficulties to the processing of the back of the substrate. First, the single-sided processed wood board needs to be cut, and then the cut wood board is manually turned over and moved to another processing station. Because the interlocking structure on the back of the substrate needs to match the keel, the back processing size of the substrate is high, especially the edge size control of the interlocking structure and the substrate. The existing processing method lacks an effective positioning mechanism, which not only has cumbersome procedures and low production efficiency, but also makes it difficult to ensure the consistency of processing accuracy. Especially in mass production, the efficiency bottleneck of this processing method is more prominent, which seriously restricts the overall production capacity of the production line. Summary of the invention

[0006] The purpose of the present invention is to provide a heat-insulating variable floor for building decoration and a turning-over processing method to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0007] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows: First, the present invention provides a heat-insulating variable floor for building decoration, comprising: The base plate is a rectangular structure, and the two long side sides are respectively provided with mutually matching locks or mortise and tenon joints, and the two short side sides are flat. The two base plates adjacent to the long side sides are buckled by the locks and the short side sides are staggered. The two base plates adjacent to the short side sides are fitted together to form a whole floor plane; the lock is a commonly used splicing structure for wooden floors, and the fast connection of the floor is achieved through the snap-on design of the mechanical structure. The mortise and tenon joint is spliced through the concave and convex structure of the wood itself, including a tenon (convex) and a mortise (concave). A convex tenon is processed on the edge of one base plate, and a concave mortise is processed at the corresponding position of the other base plate, and the tenon is inserted into the mortise and squeezed to be tightly connected; A keel frame, comprising a lower seat fixed to the ground, an upper seat arranged above the lower seat, and a crossbeam overlapped between the upper seats, the floor plane being laid on the crossbeam; The heat-insulating extruded board is laid between the beams. The heat-insulating extruded board is an XPS extruded board with a thickness of 20-30 mm. The XPS extruded board is filled in the gaps between the beams. The board seams are sealed with aluminum foil tape. The heat-insulating extruded board does not directly contact the base plate to avoid interference with the engagement between the floor plane and the beam bracket; The upper seat has an upper fitting surface, the upper fitting surface is provided with a convex cone group, the convex cone group includes a plurality of convex strips distributed at equal intervals, the lower seat has a lower fitting surface, the lower fitting surface is provided with a groove group, the groove group includes a plurality of grooves distributed at equal intervals, the convex strips are fitted with the grooves, the upper fitting surface and the lower fitting surface are inclined and fitted with each other, and the total height of the upper seat and the lower seat after fitting is adjusted by the staggered fitting of the convex strips and the grooves. The convex strip refers to a strip structure that is raised in the upper bonding surface and perpendicular to the upper bonding surface. The strip structure can be a long strip structure with an end face of an isosceles triangle or an isosceles trapezoid. Similarly, the groove refers to a long strip structure that is concave in the lower bonding surface and perpendicular to the lower bonding surface. The shape is similar to the convex strip, and the waist surfaces on both sides of the long strip structure are used as supporting and limiting surfaces to fit on the groove surface of the groove to limit the sliding of the upper bonding surface and the lower bonding surface. The bonding position of the upper seat and the lower seat is changed by fitting different convex strips and grooves. The different fitting positions can change the total height of the upper seat and the lower seat due to the fitting of the inclined upper bonding surface and the lower bonding surface.

[0008] Compared with the traditional one, the variable floor provided by the present invention adopts a keel frame with adjustable total height, which is fixed by tilting the fitting surfaces of the upper seat and the lower seat combined with the fitting of the convex strips and the grooves, so that the total height of the upper seat and the lower seat can be adjusted by the staggered fitting of the convex strips and the grooves. Compared with the traditional keel leveling which requires multiple people to cooperate in adjusting the pads and fixing them or the traditional screw-type adjustment feet to rotate multiple times to determine the height, the technical solution only needs to select the corresponding convex strips and grooves to fit up and down after obtaining the height difference. The leveling time of the variable floor is greatly reduced, and the operation is simple, reducing the work intensity.

[0009] During the height adjustment process of the variable floor, after the height difference value is determined, such as 2mm, when the height difference between the convex strips in the technical solution is set to 1mm, it is only necessary to offset two convex strips or two grooves between the upper seat and the lower seat for fitting. It should be noted that the convex strips and the grooves are offset and aligned in one direction so that the upper seat moves up along the inclined fitting surface, and the convex strips and the grooves are offset and aligned in the opposite direction so that the upper seat moves down along the inclined fitting surface.

[0010] The traditional screw-type adjustment structure relies on the thread to provide vertical support, which may cause wear (such as burrs on the nylon screw hole due to frequent adjustment), resulting in locking failure and automatic thread slippage at the adjustment point. When the load exceeds the design threshold, it may cause the adjustment screw to bend and deform. This technical solution provides stable support by fitting the upper and lower fitting surfaces, and adopts surface-to-surface fitting support, which can provide very strong support in the vertical direction.

[0011] As an extension of the above scheme, a transverse groove is provided on the top surface of the upper seat, the extension direction of the transverse groove is perpendicular to the extension direction of the convex strip and passes through the two side surfaces of the upper seat, the cross beam is overlapped in the transverse groove and the top surface of the cross beam is lower than the top surfaces of the two side portions of the transverse groove, and the top surfaces of the two side portions of the transverse groove are provided with notches for placing the insulation board support strips.

[0012] In the extended plan, the crossbeam and the upper seat are firmly overlapped in the upper seat through the cross groove, which enhances the structural stability of the entire keel frame. The top surface of the crossbeam is lower than the top surfaces of the two sides of the cross groove, ensuring that the wooden floor plane can directly contact the crossbeam, which is conducive to the uniform distribution of the load. The two sides of the cross groove are used to receive the thermal insulation extruded board. Since the top surfaces of the two sides of the cross groove are leveled by the offset of the convex strips and the grooves, the thermal insulation extruded board is also laid very flat. The notch is used to place the thermal insulation board support strips to support the thermal insulation extruded board, effectively preventing sagging and ensuring the level of the thermal insulation extruded board.

[0013] As an extension of the above solution, the bottom surface of the substrate is provided with two rows of slot groups located in the middle and a single row of slot groups adjacent to the short side surface, the row direction of the slot groups is parallel to the short side surface, the distance between the single row of slot groups and the short side surface is 1 / 2 of the row distance X between the two rows of slot groups, the slot group has first slot bodies distributed at equal intervals, and the distance between the first slot bodies and the edge of the long side of the bottom surface of the substrate is 1 / 2 of the row distance Y between adjacent first slot bodies; The top surface of the crossbeam is provided with second slots, which are arranged in two rows with a row spacing X, the row direction is arranged along the extension direction of the crossbeam, and the second slots in each row are arranged equidistantly with the row spacing Y; The first slot body and the second slot body are connected via a pin.

[0014] In the extended solution, an interlocking structure is constructed by the first trough body, the second trough body and the pin to limit the sliding or displacement of the floor plane in the horizontal direction (such as horizontal and vertical directions). At the same time, when the substrate expands or contracts slightly due to changes in environmental humidity, the interlocking structure offsets the stress to avoid problems such as movement and arching.

[0015] As an extension of the above solution, a notch is provided on the bottom surface of the substrate, the notch runs through the short side surfaces on both sides, and the notch passes through the center of the first slot body, and the slot depth of the notch is less than the slot depth of the first slot body.

[0016] The notch of the extension solution serves as a preset expansion joint, allowing the base plate to deform slightly to avoid overall arching or cracking. The notch cooperates with the first slot body to allow the base plate to have a slight expansion space when the humidity changes, avoiding cracking of the floor due to stress concentration.

[0017] As an extension of the above scheme, the extension direction of the convex strip is arranged parallel to the first side surface of the upper seat, and a fitting space between the upper fitting surface and the lower fitting surface is reserved between the two end surfaces of the convex strip in the extension direction and the boundary of the upper fitting surface, and the distance between the first side surface of the upper seat and the nearest convex strip is smaller than the spacing between adjacent convex strips.

[0018] In the extended scheme, the distance between the first side surface and the nearest convex strip is smaller than the spacing between adjacent convex strips, which can effectively ensure that when the convex strips and the grooves are staggered and aligned, the convex strips at the edges can be away from the lower bonding surface to avoid affecting the bonding between the upper bonding surface and the lower bonding surface. A bonding space is reserved at the boundary between the convex strips and the upper bonding surface, which further improves the bonding stability of the upper and lower bonding surfaces and increases the bonding area, so that the upper seat and the lower seat can provide stable support in the vertical direction after bonding.

[0019] As an extension of the above solution, the end face shape of the convex strip or the groove is triangular or trapezoidal. The triangular or trapezoidal end face shape provides support surfaces and limiting surfaces on both sides of the convex strip or the groove, and the two side faces of the convex strip and the groove surfaces on both sides of the groove are fitted face to face. Compared with the traditional screw-type adjustment structure, the fitting support and limit between the surfaces provide more stable support.

[0020] As an extension of the above solution, a triangular support portion is provided at the lateral bottom of the lower seat, and the triangular support portion is provided at the bottom of the first side surface and the bottom of another side surface opposite to the first side surface. The triangular support portion effectively enhances the horizontal stability and utilizes the stability of the right-angled triangle to enhance the anti-overturning ability of the structure.

[0021] Secondly, the present invention provides a substrate turning method, comprising the following steps: Loading process: using a conveyor belt to receive the semi-finished wood board of the previous process, the semi-finished wood board is a long strip of wood board that has been processed with the locking process on the long side and the covering layer on the top surface, and is roughly cut to a preset substrate length to obtain a substrate 1. After being roughly cut, the substrate 1 directly enters the conveyor belt and is laid flat with the front side facing upward; Flipping process: by setting guide side plates on both sides of the conveyor belt, the posture of the substrate 1 is adjusted during the conveying process, so that the short side of the substrate 1 is flush with the guide side plates, and enters the flipping station, and a lifting turntable is set on both sides of the end of the conveyor belt. The outer contour of the lifting turntable is provided with a cutting position, and a pressing belt is provided in the middle of the end of the conveyor belt. When the substrate 1 moves to contact the pressing belt, the cutting position of the lifting turntable pushes the substrate 1 to separate from the conveyor belt and move along the extension direction of the pressing belt. Then, the substrate 1 is pressed on the cutting position by the pressing belt and performs lifting and flipping movement with the rotation of the lifting turntable; Cutting process: There are two saw disks at the front end of the lifting turntable. The two saw disks are arranged outside the lifting turntable at a fixed interval. Both ends of the first substrate are cut by the saw disks on both sides during the lifting and turning-over movement, obtaining the second substrate to be processed on the back side with a precise length. The lifting turntable continues to rotate and moves the second substrate to the top. There is a conveyor belt at the top of the lifting turntable, and the second substrate enters the conveyor belt under the push of the cutting position. Back-side processing: Receive the second substrate through the conveyor belt and convey the second substrate into the milling groove station. Taking the short-side side obtained by precise cutting as the reference, process the first groove and the notch on the back side of the second substrate to obtain the finished substrate.

[0022] In this technical solution, the first substrate is flipped through the flipping process, and the short-side sides of the first substrate are cut during the flipping process. First, ensure the accurate length of the second substrate, and then use the short-side sides obtained from the cutting process as the reference for the back-side processing, providing a precise processing coordinate system for the back-side processing.

[0023] Compared with the traditional wood board cutting that requires separate cutting stations before and after the flipping process, resulting in the material needing to go through multiple handling and positioning. In this technical solution, through the coordinated movement of the lifting turntable and the saw disks, the first substrate synchronously completes the spatial attitude adjustment and end cutting during a single lifting action, eliminating the physical interval between the cutting process and the flipping process in the traditional process. Realize the spatio-temporal overlap of the substrate flipping and cutting processes, reduce the number of material turnovers, and shorten the processing cycle of a single workpiece. After the cutting action is embedded in the flipping process, there is no need to additionally set a positioning device for the cutting station, and the cutting position is directly determined by the rotation path of the lifting turntable, improving the processing accuracy and equipment utilization rate.

[0024] As an extension of the above solution, the cutting process includes: During the process that the first substrate is driven by the lifting turntable to flip and rotate, after being cut and approaching the top, since the position of the cutting position changes from being above the first substrate to being below the second substrate, the pressing belt starts to disengage from the second substrate. At this time, the second substrate is supported by the cutting position, and this cutting position supports the second substrate to move to the top under the continuous rotation of the lifting turntable and is pushed into the conveyor belt at the top.

[0025] In the extended solution, when the first substrate rotates to the saw disk cutting area, the two ends of the suspended part are synchronously cut by the high-speed rotating saw disks, obtaining the short-side sides on both sides. Solve the problem that the traditional wood board flipping requires an independent grabbing mechanism and other operations for flipping. This extended solution effectively integrates the cutting and flipping processes of the substrate, uses the pressing belt to press the first substrate, makes the lifting and flipping movement along with the rotation of the lifting turntable, and at the same time uses the saw disks for cutting treatment during the lifting and flipping movement, realizing that cutting, lifting, and flipping are completed in one process, improving production efficiency.

[0032] Refer to Figures 1 to 6 , and several embodiments of a heat-insulating variable floor for building decoration and a turning processing method thereof according to the present invention are given below.

[0033] As Figure 1 and Figure 2 and Figure 4 shown, in some embodiments, a heat-insulating variable floor for building decoration includes: A base plate 100, which is a rectangular structure, with mutually cooperating locking buttons respectively provided on the two long-side sides 110, the two short-side sides 120 are flat, the two base plates 100 adjacent to the long-side side 110 are buckled through the locking buttons and the short-side sides 120 are staggered from each other, and the base plates adjacent to the short-side sides are attached to each other to form an integral floor plane; A floor joist frame 200, which has a lower seat 210 fixed on the ground, an upper seat 220 arranged above the lower seat 210, and a cross beam 230 lapped between the upper seats 220, and the wooden floor plane is laid on the cross beam 230; A heat-insulating extruded board 300, which is laid between the cross beams 230; the heat-insulating extruded board is an XPS extruded board with a thickness of 20 - 30 mm, the XPS extruded board is filled in the gaps between the cross beams, and the board joints are sealed with aluminum foil tape. The heat-insulating extruded board does not directly contact the base plate to avoid interfering with the bite between the floor plane and the cross beam support. In some preferred embodiments, a PE moisture-proof film with a thickness of 0.2 mm is pasted on the bottom surface of the XPS extruded board to further prevent ground moisture from penetrating; The upper seat 220 has an upper fitting surface 221, and a convex cone group is provided on the upper fitting surface 221. The convex cone group includes several convex strips 222 distributed at equal intervals. The lower seat 210 has a lower fitting surface 211, and a groove group is provided on the lower fitting surface 211. The groove group includes several grooves 212 distributed at equal intervals. The convex strips 222 are attached to the grooves 212, and the upper fitting surface 221 and the lower fitting surface 211 are inclined and attached to each other. The total height after the upper seat 220 and the lower seat 210 are attached is adjusted by the misaligned attachment of the convex strips 222 and the grooves 212.

[0034] In this embodiment, the two side waist surfaces of the rib 222 are used as the surfaces for support and limit, and are attached to the groove surface of the groove 212 to restrict the sliding of the upper attachment surface 221 and the lower attachment surface 211. By staggering and attaching different ribs 222 and grooves 212, the attachment position of the upper seat 220 and the lower seat 210 is changed. Due to the attachment of the inclined upper attachment surface 221 and the lower attachment surface 211 at different attachment positions, the total height of the upper seat 220 and the lower seat 210 is changed.

[0035] In some specific embodiments, during the adjustment of the keel height, when the height difference value is determined (such as 1 mm), when the height difference between adjacent ribs in this technical solution is set to 1 mm, only one rib or one groove needs to be staggered between the upper seat and the lower seat for attachment. For example, Figure 3 As shown in the left part of the figure, the rib 222 and the groove 212 are staggered and aligned in one direction, and the upper seat 220 moves up 1 mm along the inclined attachment surface. When the construction ground base is 1 mm higher, the rib 222 and the groove 212 are staggered and aligned in the opposite direction, as Figure 3 shown in the right part of the figure, and the upper seat 220 moves down 1 mm along the inclined attachment surface. It should be noted that the specific value of the increase or decrease is determined according to the inclination angle of the upper and lower attachment surfaces, as well as the protrusion height or the concave depth and spacing of the rib or groove. Technicians set it according to the actual use situation. And during the process of adjusting the keel height, the construction personnel should be familiar that the attachment area of the attachment surface between the upper seat and the lower seat should not be too small, such as not less than half or 2 / 3 of the entire attachment surface area, etc. In more specific embodiments, scale line marks are made on the side surfaces of the upper seat and the lower seat corresponding to the ribs or grooves, or indication marks for the maximum staggered position are given. The specific setting is based on the actual sizes of the upper seat and the lower seat, and will not be elaborated too much in this embodiment.

[0036] Compared with the traditional one, the variable floor provided in this embodiment has a keel frame that can change the total height. Through the inclined setting of the attachment surfaces of the upper seat and the lower seat, and combined with the attachment of the ribs and grooves to achieve fixation, the total height of the upper seat and the lower seat is changed by staggering the attachment of the ribs and grooves. Compared with the traditional keel leveling that requires multiple people to cooperate to adjust the pads and fix them, or the traditional screw-type adjustable feet that need to be rotated multiple times to determine the height, in this embodiment, only the corresponding ribs and grooves need to be attached up and down after obtaining the height difference. The leveling time of the variable floor is greatly reduced, and the operation is simple, reducing the working intensity.

[0037] The traditional screw-type adjustment structure relies on the thread to provide vertical support, and there is wear (such as burrs in the nylon screw hole due to frequent adjustment), which may lead to locking failure and automatic thread slippage and falling of the adjustment point. When the load exceeds the design threshold, it may cause the adjustment screw to bend and deform. This embodiment provides stable support by fitting the upper fitting surface and the lower fitting surface, and adopts surface-to-surface fitting support, which can provide very strong support in the vertical direction. At the same time, the keel frame provided by this embodiment can meet standard modular production. After each component is processed and formed in batches separately, it does not need to be assembled and can be directly delivered to the construction site in the form of accessories. The height adjustment during the construction process is also extremely simple, which has the characteristics of simplifying production to reduce production costs and reducing construction difficulty to improve product competitiveness.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, a transverse groove 223 is provided on the top surface of the upper seat 220, and the extension direction of the transverse groove 223 is perpendicular to the extension direction of the convex strip 222 and passes through the two side surfaces of the upper seat 220. The cross beam 230 is overlapped in the transverse groove 223 and the top surface of the cross beam 230 is lower than the top surfaces of the two side portions of the transverse groove 223. The top surfaces of the two side portions of the transverse groove 223 are provided with notches 225 for placing the heat insulation board support strips 310.

[0039] In this embodiment, the crossbeam and the upper seat are firmly overlapped in the upper seat through the cross groove, which enhances the structural stability of the entire keel frame. The top surface of the crossbeam is higher than or flush with the top surface of the upper seat, ensuring that the plane of the wooden floor can directly contact the crossbeam, which is beneficial to the uniform distribution of the load. The two sides of the cross groove are used to receive the thermal insulation extruded board. Since the top surfaces of the two sides of the cross groove are leveled by the offset of the convex strips and the grooves, the thermal insulation extruded board can be laid very flat. The notch is used to place the thermal insulation board support strip to support the thermal insulation extruded board, effectively preventing sagging and ensuring the level of the thermal insulation extruded board.

[0040] Compared with the traditional method of laying XPS boards under the keel to achieve thermal insulation, the XPS boards are locally compressed and dented, resulting in a decrease in the flatness of the floor surface (height difference > 5mm / 2m), affecting walking comfort. In this embodiment, the thermal insulation extruded board is arranged between the beams, and is supported by the top surfaces of the two sides of the horizontal groove and the thermal insulation board support strips. It does not need to bear the load of the keel. The thermal insulation extruded board is mainly used for filling and heat preservation. In this embodiment, the thickness of the thermal insulation extruded board is set to be lower than the height of the top surface of the upper seat protruding from the beam. It does not need to bear the load of the substrate, avoiding creep under long-term load.

[0041] It can be understood by those skilled in the art that the upper seat and the lower seat form a keel seat supporting the cross beam. Since the cross groove is set through, the keel seat can be evenly distributed in the middle of the cross beam, or it can be set at the end position where the two cross beams meet (such as Figure 1The keel seat in the middle left part is supported by two beams as shown), and the specific position setting of the keel seat and the beams for supporting is determined according to the actual construction site, and this embodiment will not be elaborated in detail.

[0042] In some specific embodiments, when a keel seat is used to support the ends of two beams, semicircular grooves are opened in the vertical direction on the sides where the beams are connected to the transverse grooves. The semicircular grooves on both sides form circular holes, which are fixed by inserting circular pins. This prevents the two beams from detaching, thereby further improving the structural stability of the keel frame.

[0043] like Figure 1 and Figure 4 and Figure 5 As shown, in some embodiments, the bottom surface of the substrate 100 is provided with two rows of slot groups 130 located in the middle and a single row of slot groups adjacent to the short side surface 120, the row direction of the slot group 130 is parallel to the short side surface 120, the distance between the single row of slot groups and the short side surface 120 is 1 / 2 of the row distance X between the two rows of slot groups, the slot group has first slot bodies 131 distributed at equal intervals, and the distance between the first slot bodies 131 and the edge of the long side of the bottom surface of the substrate 100 is 1 / 2 of the row distance Y between adjacent first slot bodies 131; The top surface of the crossbeam 230 is provided with second slots 231, and the second slots 231 are arranged in two rows with a row spacing X, the row direction is arranged along the extension direction of the crossbeam 230, and the second slots 231 in each row are arranged equidistantly with the row spacing Y; The first slot body 131 and the second slot body 231 are connected via a pin 232 .

[0044] In this embodiment, an interlocking structure is constructed by the first trough body, the second trough body and the pin column to limit the sliding or displacement of the floor plane in the horizontal direction (such as horizontal and vertical directions). At the same time, when the substrate expands or contracts slightly due to changes in environmental humidity, the interlocking structure offsets the stress to avoid problems such as movement and arching. Through multi-point uniform distribution, the pedaling force can be dispersed to the keel to reduce local pressure. In this embodiment, the interlocking structure can significantly improve the overall bearing performance in areas with large traffic (such as corridors, living rooms, shopping malls) or when the weight of the laid substrate is large. In some specific embodiments, waterproof glue is applied or a rubber gasket is installed at the contact point between the pin column and the first trough body or the second trough body to prevent moisture from penetrating and causing the wood to expand and deform.

[0045] like Figure 4 and Figure 5 As shown, in some embodiments, a notch 140 is provided on the bottom surface of the substrate 100 , and the notch 140 is arranged through the short side surfaces 120 on both sides, and the notch 140 passes through the center of the first groove body 131 , and the groove depth of the notch 140 is less than the groove depth of the first groove body 131 .

[0046] When the wood expands due to moisture absorption or shrinks due to drying, the notch in this embodiment serves as a preset expansion joint, allowing the substrate to deform slightly and avoiding overall arching or cracking. In this embodiment, the notch direction is consistent with the wood fiber direction (parallel to the length of the substrate), and by utilizing the transverse elastic deformation ability of the wood, the stress is concentrated in the notch area to protect the main structure of the substrate. The notch, in cooperation with the first groove body, allows the substrate to have a small amount of expansion space when the humidity changes, avoiding floor cracking caused by stress concentration.

[0047] As Figure 2 shown, in some embodiments, the extending direction of the rib 222 is parallel to the first side surface 224 of the upper seat 220. There is a fitting space between the upper fitting surface 221 and the lower fitting surface 211 reserved between the two end faces of the rib 222 in the extending direction and the boundary of the upper fitting surface 221. The distance between the first side surface 224 of the upper seat 220 and the closest rib 222 is less than the distance between adjacent ribs 222.

[0048] In this embodiment, the distance between the first side surface and the closest rib is less than the distance between adjacent ribs, which can effectively ensure that when the rib and the groove are staggered and aligned, the rib at the edge can be far away from the lower fitting surface, avoiding affecting the fitting between the upper fitting surface and the lower fitting surface. There is a fitting space reserved between the rib and the boundary of the upper fitting surface, further improving the fitting stability of the upper and lower fitting surfaces, increasing the fitting area, and providing stable support in the vertical direction after the upper seat and the lower seat are fitted.

[0049] In some embodiments, the end face shape of the rib or the groove is triangular or trapezoidal. The triangular or trapezoidal end face shape provides two side support surfaces and limiting surfaces for the rib or the groove. Preferably, the end face shape is an isosceles triangle or an isosceles trapezoid. The two side surfaces of the rib are in surface-to-surface contact with the two side surfaces of the groove. Compared with the traditional screw-type adjustment structure, the surface-to-surface contact support and limitation provide more stable support.

[0050] As Figure 2 described, in some implementations, a triangular support portion 213 is provided at the bottom of the side of the lower seat 210. The triangular support portion 213 is provided at the bottom of the first side surface 224 and the bottom of the other side surface opposite to the first side surface 224. The triangular support portion effectively enhances the horizontal stability and utilizes the stability of the right triangle to enhance the anti-overturning ability of the structure. At the same time, the triangular support portion can provide construction space for the fixed connection between the lower seat and the ground base layer. By providing a counterbore in the triangular support portion and setting a fixing lock nail in the counterbore to act on the ground base layer, in some specific embodiments, the triangular support portion can also be set as a right-angle support member without a hypotenuse, and the bottom surface of the direct support member is fixed to the ground base layer through fixing members such as lock nails and explosive bolts.

[0051] On the other hand, the present invention provides a method for turning over a substrate. Refer to Figure 4 and Figure 6 , and the method includes the following steps: Loading process: Use a conveyor belt 410 to receive the semi-finished wooden board 400 from the previous process. The semi-finished wooden board 400 is a substrate one obtained by performing a buckle process on the long-side side and a top surface veneer process on the top surface of a wooden board strip and then performing rough cutting on the substrate at a predetermined substrate length. After rough cutting, the substrate one directly enters the conveyor belt 410 and is laid flat with the front side facing up; Turning process: Adjust the posture of the substrate one during transportation through guiding side plates 420 provided on both sides of the conveyor belt 410, so that the short-side side of the substrate one is flush with the guiding side plates 420 and enters the turning station 430. Lifting turntables 440 are provided on both sides at the end of the conveyor belt 410. A cutting position 441 is provided on the outer contour of the lifting turntable 440. A pressing belt 450 is provided in the middle at the end of the conveyor belt 410. When the substrate one moves to contact the pressing belt 450, the cutting position 441 of the lifting turntable 410 pushes the substrate one away from the conveyor belt 410 and moves along the extending direction of the pressing belt 450. Subsequently, the substrate one is pressed by the pressing belt 450 on the cutting position 441 and performs a lifting and turning movement as the lifting turntable 440 rotates; Cutting process: Two saw disks 460 are provided at the front end of the lifting turntable 440. The two saw disks 460 are arranged at a fixed distance outside the lifting turntable 440. Both ends of the substrate one are cut by the saw disks 460 on both sides during the lifting and turning movement to obtain a substrate two with a precise length to be processed on the back surface. The lifting turntable 440 continues to rotate to move the substrate two to the top. A conveyor belt 470 is provided at the top of the lifting turntable 440. The substrate two enters the conveyor belt 470 under the push of the cutting position 441; Back surface processing: Receive the substrate two through the conveyor belt 470 and convey the substrate two into a milling groove station. Taking the short-side side 120 obtained by precise cutting as a reference, process a first groove 131 and a notch 140 on the back surface of the substrate two to obtain the finished substrate 100 as shown in Figure 4 .

[0052] In the present embodiment, the semi-finished wood board has completed the processing and production of the pre-process before falling into the conveyor belt, such as the locking process of the long side, the dovetail setting process in the substrate, the top surface covering layer process, and the rough cutting process of the long strips of wood board with a preset substrate length, etc. It should be noted that the above-mentioned pre-process can be realized by adopting the existing process. Based on this, the back process of the substrate needs to be processed between the semi-finished wood board and the finished substrate (the back process is the processing process of the bottom surface structure of the substrate in the above-mentioned embodiment). In the traditional technical scheme, the semi-finished wood board obtained by the pre-process is obtained by cutting in the wooden strips produced in the long strips. The present embodiment sets a conveyor belt docking cutting process to obtain a semi-finished wood board, namely substrate one. The substrate one directly enters the conveyor belt after rough cutting, and is laid flat with the front side facing up.

[0053] In this embodiment, substrate one is flipped through a flipping process, and the short side cutting of substrate one is completed during the flipping process, first ensuring the length of substrate one is accurate, and then the short side obtained in the cutting process is used as a reference for the back side process processing, providing an accurate processing coordinate system for the back side process processing.

[0054] Traditional wood board cutting requires separate cutting stations before and after the flipping process, which means that the material needs to be transported and positioned multiple times. However, this embodiment uses the coordinated movement of the lifting turntable and the saw disc to simultaneously complete the spatial posture adjustment and end cutting of the substrate in a single lifting action, eliminating the physical separation between the cutting process and the flipping process in the traditional process. This embodiment achieves the time and space overlap of the flipping of the substrate and the cutting process, reduces the number of material turnovers, and shortens the processing cycle of a single workpiece. After the cutting action is embedded in the flipping process, there is no need to set up an additional positioning device for the cutting station. The cutting position can be directly determined by using the rotation path of the lifting turntable, thereby improving processing accuracy and equipment utilization.

[0055] In some specific embodiments, Figure 6 As shown, the lifting turntable 440 is a ratchet-shaped rotating structure, and a cutting position 441 is provided on its outer contour. The cutting position 441 includes a rear side surface 4411 for pushing the movement of substrate one and a supporting surface 4412 in contact with the top surface of substrate one. The rear side surface 4411 is used to push the rear side of substrate one when the lifting turntable 440 rotates to the flipping station 430, so that substrate one is forced to move forward. At the same time, since the pressure belt 450 is inclined in this section, substrate one begins to separate from the conveyor belt 410 and moves upward along the pressure belt 450 until it contacts the supporting surface 4412 of the lifting turntable 440. The pressure belt 450 is an elastic belt (the positional relationship and structure of the pressure belt are specifically described in some of the following embodiments). At this time, the pressure belt 450 presses substrate one on the supporting surface 4412, and performs a lifting and flipping movement as the lifting turntable 440 rotates.

[0056] It should be noted that a sensor is provided before the first substrate enters the flipping station to control the rhythm of the first substrate entering the flipping station. This can be achieved by controlling the rotation state of the conveyor belt or setting the rotation parameters of the gate and the lifting turntable, so as to avoid interference when the cutting position rotates to the height of the top surface of the first substrate and abuts against the top surface of the first substrate. In actual production, controlling the circumferential rotation distance of the lifting turntable and the gap between the first substrate entering the flipping station can avoid the interference between the first substrate and the lifting turntable. Technicians can set it by means of existing technologies according to the actual production situation, the size of the equipment and the running speed, and will not elaborate here.

[0057] In some preferred embodiments, a bearing plate for increasing the bearing area of the support surface is provided at the cutting position on the support surface. The bearing plate is fixed inside the lifting turntable through a locking member to avoid interference with the saw blade arranged outside. The bearing plate increases the contact area with the first substrate, effectively improving the stability of the first substrate during cutting in the lifting and flipping movement.

[0058] In some specific embodiments, as Figure 6 shown, the pressing belt 450 is arranged at the position between the two conveyor belts 410, that is, between the two lifting turntables 440. The pressing belt 450 is connected by four groups of pulley sets. The first pulley set 451 is arranged at a position slightly below the middle under the lifting turntable 440 and lower than the position of the first substrate on the conveyor belt 410. The second pulley set 452 is arranged at a position slightly above the middle above the lifting turntable 440. The third pulley set 453 and the fourth pulley set 454 are arranged in front of the lifting turntable 440. The pressing belt 450 is sleeved on all the pulley sets to form a closed-loop elastic belt. The elastic belt between the first pulley set 451 and the second pulley set 452 is pressed into the space between the two lifting turntables 440 and abuts against the connecting rod 442. The connecting rod 442 is a structure connecting the two lifting turntables 440 and is circumferentially distributed around the axis of the lifting turntable 440.

[0059] When the first substrate is conveyed by the conveyor belt to contact the pressing belt, since the installation height of the first pulley set is lower than the bearing surface of the conveyor belt, the pressing belt forms a block at the junction of the two, forcing the first substrate to stop at the junction of the pressing belt and the conveyor belt. At this time, the lifting turntable rotates, so that the rear side of the cutting position pushes the rear side of the wooden board. The pressing belt forms an inclined upward running path between the first pulley set and the lifting turntable, guiding the first substrate to move along this path. When the rear side pushes the first substrate to move, the first substrate is already in the support surface. As the lifting turntable rotates, the pressing belt presses the first substrate against the support surface. As the lifting turntable continues to rotate, the pressing belt generates a continuous pressing force through the belt section pressed into the space between the two lifting turntables, then presses the first substrate against the support surface, and rotates with the lifting turntable to perform the lifting and flipping movement.

[0060] In some embodiments, the cutting process includes: When Substrate 1 is turned over and rotated by the lifting turntable after being cut and approaching the top, the position of the cutting position changes from being above Substrate 1 to being below Substrate 2, and the clamping belt begins to separate from Substrate 2. At this time, Substrate 2 is taken over by the cutting position, which takes over Substrate 2 and moves it to the top as the lifting turntable continues to rotate, and pushes it into the conveyor belt at the top.

[0061] In this embodiment, when the substrate 1 rotates to the saw disc cutting area, the suspended parts at both ends are synchronously cut by the high-speed rotating saw disc to obtain the short side surfaces on both sides. The substrate 2 that has completed the cutting continues to rotate to the top and leaves the cutting position to enter the conveyor belt. Here, the pressing belt no longer presses the substrate 2 due to the position relationship of the second wheel group, and the support surface has changed from facing downward to facing upward and tending to be horizontal after rotation, which can support the substrate 2. The substrate 2 on the support surface slides into the conveyor belt through the pushing action of the rear side. During the whole process, the substrate 1 automatically enters the lifting turntable along the conveyor belt and is pressed by the pressing belt to perform lifting and turning movement. The turning and cutting are completed during the lifting and turning movement. There is space under the lifted substrate 2, which is convenient for the discharge of wood chips and waste. The wood chips generated during the cutting process can fall naturally under the action of gravity, avoiding the accumulation of wood chips in the cutting area, affecting the cutting effect and the life of the tool, and also helping to keep the working environment clean. In actual production, a machine cover is set to cover the space where the saw disc is located to prevent wood chips from splashing.

[0062] In some embodiments, the backside processing includes: When the second substrate enters the milling station, the second substrate is positioned, and the short side surface is used as the reference in the X direction, and the long side surface is used as the reference in the Y direction. The processing coordinate system of the first slot body and the slot opening on the back of the second substrate is constructed, and the first slot body and the slot opening on the back of the second substrate are precisely milled through the processing coordinate system to obtain the finished substrate. The finished substrate has a first slot body with accurate dimensions, and a bite structure is constructed by the first slot body and the second slot body of the crossbeam and the pin column to limit the sliding or displacement of the substrate in the horizontal direction (such as horizontal and vertical directions). At the same time, when the substrate expands or contracts slightly due to changes in environmental humidity, the bite structure offsets the stress to avoid problems such as movement and arching.

[0063] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
