Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building decoration engineering, in particular to a heat-insulating variable floor for building decoration and a turning method. BACKGROUND

[0002] In the building decoration engineering, the heat-insulating floor is used to insulate the ground moisture, protect the floor, and also can be used to maintain the indoor constant temperature (such as keeping warm in winter and heat insulation in summer in the shopping mall), reduce the air conditioning energy consumption, and usually includes a keel laid on the ground, a floor laid on the keel, and a heat-insulating layer laid between the keel and the floor or between the ground and the floor. The compressive strength of the heat-insulating layer needs to match the floor load, the heat-insulating layer is located below the keel and needs to bear the load of the keel and the floor, and the compressive strength (150-300 kPa) of the conventional heat-insulating material (such as XPS extruded board) meets the empty load requirement, but the creep under long-term load will cause support failure; if the heat-insulating layer is located between the keel and the floor, it will occupy the installation space of the interlocking structure, causing interlocking interference.

[0003] In the existing floor paving, the base plate is directly laid above the keel without physical connection, and the connection strength depends on the performance of the material itself (such as the nail holding force of wood and the durability of adhesive), and these ways do not form a geometric interlocking interlocking structure. Without the interlocking structure, the static friction force between the base plate and the keel is the only anti-sliding force, and the horizontal force generated by the rapid movement of personnel or the dragging of furniture will cause the base plate to slide horizontally. When the base plate bears a concentrated load (such as the local pressure of furniture legs > 150 kg), the lack of interlocking structure will cause the load to be unable to be effectively dispersed to the keel, which may cause local crushing of the base plate or unilateral overload fracture of the keel.

[0004] After the floor is paved, it needs to rely on the flat base layer to disperse the load, and if the base layer is uneven, the floor will appear due to local suspension or stress concentration, and the large ups and downs of the ground may affect the locking and interlocking strength between the base plates. The traditional screw type adjusting foot (such as metal bolt + nylon pad) has uneven stress on the adjusting structure, and when the load exceeds the design threshold, the adjusting screw may be bent and deformed, and the dynamic load generated by the movement of personnel or furniture will make the adjusting structure repeatedly bear shear force and tension force. The metal parts (such as steel screws) are prone to fatigue fracture and failure, and the plastic adjusting parts (such as ABS material) may lose the adjusting function due to creep deformation.

[0005] Meanwhile, the engagement structure between the substrate and the keel brings difficulties to the back processing of the substrate. First, the single-sided processed wood board needs to be cut, then the cut wood board is manually turned over and moved to another processing station. Because the back of the substrate needs to be matched with the keel, the back processing size of the substrate is required to be high, especially the edge size control of the engagement structure and the substrate. The existing processing method lacks effective positioning mechanism, which not only is complicated and low in production efficiency, but also is difficult to ensure the consistency of processing precision. 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

[0006] The present application aims to provide a heat-insulating variable floor for building decoration and a back processing method to solve one or more technical problems existing in the prior art, at least to provide a beneficial choice or create conditions.

[0007] To solve the above technical problems, the technical solutions adopted by the present application are as follows:

[0008] Firstly, the present application provides a heat-insulating variable floor for building decoration, comprising:

[0009] The substrate is of rectangular structure, and the two long sides are respectively provided with mutually matched locks or mortise and tenon joints, and the two short sides are flat. The two substrates adjacent to the long sides are connected by the locks, and the short sides are staggered. The two substrates adjacent to the short sides are matched to form a whole floor plane. The lock is a common splicing structure of wood floor, which realizes the rapid connection of the floor through the buckle design of mechanical structure. The mortise and tenon joint is spliced through the concave-convex structure of wood itself, including a tenon (convex) and a mortise hole (concave). The tenon is protruded at the edge of one substrate, and the mortise hole is recessed at the corresponding position of the other substrate. The tenon is inserted into the mortise hole and tightly connected by extrusion.

[0010] The keel frame has a lower seat fixed to the ground, an upper seat arranged above the lower seat, and a cross beam lapped between the upper seats. The floor plane is laid on the cross beam.

[0011] The heat-insulating extruded board is laid between the cross beams. The heat-insulating extruded board is XPS extruded board with a thickness of 20-30 mm. The gap between the cross beams is filled with XPS extruded board, and the board joint is sealed with aluminum foil tape. The heat-insulating extruded board does not directly contact with the substrate, avoiding interference with the engagement between the floor plane and the cross beam support.

[0012] 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 strip is fitted with the groove, the upper fitting surface and the lower fitting surface are arranged in an inclined manner and are fitted with each other, and the total height of the upper seat and the lower seat after fitting is adjusted through the misaligned fitting of the convex strip and the groove. The convex strip refers to a strip structure that protrudes in the upper fitting surface and is perpendicular to the upper fitting surface. The strip structure can be a long strip structure with an isosceles triangular or isosceles trapezoidal end face. Similarly, the groove refers to a long strip structure that is recessed in the lower fitting surface and is perpendicular to the lower fitting surface. The shape is similar to the convex strip for cooperation. The long strip structure uses the two side waist surfaces as supporting and limiting surfaces to fit the groove surface, thereby limiting the sliding of the upper fitting surface and the lower fitting surface. By misaligning the different convex strips and grooves, the fitting position of the upper seat and the lower seat is changed. Due to the inclined fitting of the upper fitting surface and the lower fitting surface, the total height of the upper seat and the lower seat can be changed.

[0013] Compared with the traditional one, the variable floor provided by the present application adopts an adjustable total height keel frame. The fitting surfaces of the upper seat and the lower seat are arranged in an inclined manner, and the fitting of the convex strip and the groove is combined to realize fixation. The total height of the upper seat and the lower seat is adjusted through the misaligned fitting of the convex strip and the groove. Compared with the traditional keel leveling, which requires multiple people to adjust the pads and fix them or the traditional screw type adjustment foot, which needs to be rotated multiple times to determine the height, the present technical solution only needs to select the corresponding convex strip and groove 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 and convenient, thereby reducing the work intensity.

[0014] During the height adjustment process of the variable floor, when the height difference value is determined, such as 2 mm, and the height difference between the convex strips in the present technical solution is set to 1 mm, only two convex strips or two grooves between the upper seat and the lower seat need to be misaligned and fitted. It is noted that the convex strip and the groove are misaligned in one direction to align the upper seat to move along the inclined fitting surface to rise, and misaligned in the opposite direction to align the convex strip and the groove to fit the upper seat to move along the inclined fitting surface to lower.

[0015] The traditional screw type adjustment structure relies on threads to provide vertical support, which may cause locking failure due to wear (such as burrs on nylon screw holes due to frequent adjustment) and automatic sliding of the adjustment point. When the load exceeds the design threshold, the adjustment screw may be bent and deformed. The present technical solution provides stable support through the fitting of the upper fitting surface and the lower fitting surface. The face-to-face fitting support can provide very strong support in the vertical direction.

[0016] As an extension of the above scheme, the top surface of the upper seat is provided with a transverse groove, the extension direction of the transverse groove is perpendicular to the extension direction of the convex strip and penetrates through the two side surfaces of the upper seat, the cross beam is lapped in the transverse groove and the top surface of the cross beam is lower than the top surface of the two side surfaces of the transverse groove, the top surface of the two side surfaces of the transverse groove is provided with a notch for placing the heat insulation plate support strip.

[0017] In the extended scheme, the cross beam is stably lapped in the upper seat through the transverse groove, which enhances the structural stability of the whole keel frame, the top surface of the cross beam is lower than the top surface of the two side surfaces of the transverse groove, which ensures that the wood floor plane can directly contact with the cross beam, which is conducive to the uniform distribution of load, and the two side surfaces of the transverse groove are used to receive the heat insulation extruded plate, because the top surface of the two side surfaces of the transverse groove is leveled by the misalignment of the convex strip and the groove, so that the laying of the heat insulation extruded plate is also very flat, the notch is used to place the heat insulation plate support strip for supporting the heat insulation extruded plate, which effectively prevents sagging and protects the level of the heat insulation extruded plate.

[0018] As an extension of the above scheme, the bottom surface of the base plate is provided with two column groove groups in the middle and a single column groove group adjacent to the short side surface, the column direction of the groove group is parallel to the short side surface, the distance between the single column groove group and the short side surface is 1 / 2 of the column distance X between the two column groove groups, the groove group has equidistantly distributed first groove bodies, and the distance between the first groove body and the long edge of the bottom surface of the base plate is 1 / 2 of the row distance Y between adjacent first groove bodies.

[0019] The top surface of the cross beam is provided with second groove bodies, the second groove bodies are arranged in two columns with a column distance X, the column direction is arranged along the extension direction of the cross beam, and the second groove bodies of each column are equidistantly arranged with the row distance Y.

[0020] The first groove body and the second groove body are connected by a pin column.

[0021] In the extended scheme, the first groove body, the second groove body and the pin column construct an engagement structure to limit the sliding or displacement of the floor plane in the horizontal direction (such as the transverse direction and the longitudinal direction), and at the same time, when the base plate slightly expands or shrinks due to changes in environmental humidity, the engagement structure can offset the stress to avoid problems such as shifting and arching.

[0022] As an extension of the above scheme, the bottom surface of the base plate is provided with a slot, the slot is arranged through the two side short side surfaces, and the slot passes through the center of the first groove body, and the slot depth is less than the groove depth of the first groove body.

[0023] The slot of the extended scheme serves as a pre-set expansion joint, allowing the base plate to deform slightly, avoiding overall arching or cracking. The slot allows the base plate to have a small amount of expansion space when the humidity changes through the cooperation with the first groove body, avoiding the floor from cracking due to stress concentration.

[0024] As an extension of the above scheme, the extension direction of the convex strip is parallel to the first side surface of the upper seat, and the two end surfaces of the convex strip in the extension direction are reserved with the bonding space between the upper bonding surface and the lower bonding surface, and the distance between the first side surface of the upper seat and the closest convex strip is less than the interval between adjacent convex strips.

[0025] In the extended scheme, the distance between the first side surface and the closest convex strip is less than the interval between adjacent convex strips, which can effectively ensure that when the convex strip and the groove are misaligned, the edge of the convex strip can be away from the lower bonding surface, avoiding affecting the bonding between the upper bonding surface and the lower bonding surface, and the boundary of the convex strip and the upper bonding surface is reserved with a bonding space, further improving the bonding stability of the upper and lower bonding surfaces, increasing the bonding area, so that the upper seat provides stable support in the vertical direction after being bonded with the lower seat.

[0026] As an extension of the above scheme, the end surface shape of the convex strip or the groove is triangular or trapezoidal. The triangular or trapezoidal end surface shape provides two side supporting surfaces and limiting surfaces for the convex strip or the groove, and the two side surfaces of the convex strip and the two side groove surfaces realize surface-to-surface bonding, which provides more stable support than the traditional screw rod type adjusting structure.

[0027] As an extension of the above scheme, the side bottom of the lower seat is provided with a triangular supporting part, and the triangular supporting part is arranged at the bottom of the first side surface and the bottom of the other side surface opposite to the first side surface. The triangular supporting part effectively enhances the horizontal stability and enhances the anti-overturning ability by using the stability of the right-angled triangle.

[0028] Secondly, the present application provides a substrate turning processing method, comprising the following steps:

[0029] The feeding process: receiving the semi-finished wood board of the previous process by the conveying belt, the semi-finished wood board is a wood board strip that has completed the lock catch process treatment of the long side surface and the top surface covering layer process treatment, and is coarsely cut into a substrate I with a pre-set substrate length, the substrate I is directly placed on the conveying belt after being coarsely cut, and is arranged in a flat manner with the front surface upward;

[0030] The turning process: adjusting the posture of the substrate I in the conveying process by the guide side plates arranged on both sides of the conveying belt, so that the short side surface of the substrate I is flush with the guide side plates, and the substrate I enters the turning station, the lifting turntable is arranged at the ends of the conveying belt, the outer contour of the lifting turntable is provided with a cutting position, the middle part of the end of the conveying belt is provided with a pressing belt, when the substrate I moves to contact the pressing belt, the substrate I is pushed off the conveying belt by the cutting position of the lifting turntable and moves along the extension direction of the pressing belt, and then the substrate I is pressed on the cutting position by the pressing belt and is lifted and turned over by the rotation of the lifting turntable;

[0031] Cutting process: two saw discs are arranged at the front end of the lifting turntable, and the two saw discs are arranged at a fixed interval outside the lifting turntable, the two ends of the base plate one are cut by the saw discs on both sides in the lifting and turning movement, and the base plate two with a precise length is obtained, and the lifting turntable continues to rotate to move the base plate two to the top, and a conveying belt is arranged at the top of the lifting turntable, and the base plate two is pushed into the conveying belt at the cutting position.

[0032] Back process: the base plate two is received by the conveying belt and conveyed into the milling groove station, and the back of the base plate two is processed into a first groove body and a groove opening based on the short side surface obtained by precise cutting, so that the finished base plate is obtained.

[0033] The base plate one is turned over by the turning process, and the short side surface of the base plate one is cut during the turning process, so that the length of the base plate two is ensured to be accurate, and then the short side surface obtained by the cutting process is used as a reference for back process, so that a precise processing coordinate system is provided for the back process.

[0034] Compared with the traditional wood board cutting, the cutting station needs to be separately arranged before and after the turning process, so that the material needs to be transported and positioned for multiple times. In the technical solution, the lifting turntable and the saw disc are cooperatively moved, so that the base plate one is simultaneously subjected to space posture adjustment and end cutting in a single lifting action, and the physical interval between the cutting process and the turning process in the traditional process is eliminated. The space-time overlap of the base plate turning and the cutting process is realized, the number of material turnovers is reduced, and the processing cycle of a single workpiece is shortened. After the cutting action is embedded in the turning process, the positioning device of the cutting station is not needed, and the cutting position is directly determined by the rotation path of the lifting turntable, so that the processing precision and the equipment utilization rate are improved.

[0035] As an extension of the above-mentioned solution, the cutting process comprises:

[0036] During the process that the base plate one is lifted and rotated by the lifting turntable and approaches the top after being cut, the position of the cutting position is changed from being above the base plate one to being below the base plate two, the pressing belt starts to separate from the base plate two, the base plate two is supported by the cutting position at this time, the cutting position supports the base plate two to move to the top under the continuous rotation of the lifting turntable, and the base plate two is pushed into the conveying belt at the top.

[0037] In the extended solution, when the base plate one is rotated to the saw disc cutting area, the two end overhanging parts are synchronously cut by the high-speed rotating saw disc to obtain the short side surfaces on both sides. The extension solution effectively integrates the cutting and turning processes of the base plate, presses the base plate one by the pressing belt, lifts and turns over the base plate one with the rotation of the lifting turntable, cuts the base plate one in the lifting and turning movement, completes the cutting, lifting and turning over in one process, and improves the production efficiency.

[0052] In the description of the present application, unless otherwise explicitly limited, the words such as setting, mounting, connecting and the like should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0053] Referring to Figures 1 to 6 , the following will give several embodiments of a heat-insulating variable floor for building decoration and a turning processing method.

[0054] As Figure 1 and Figure 2 and Figure 4 shown, in some embodiments, a heat-insulating variable floor for building decoration comprises:

[0055] The base plate 100 is of a rectangular structure, and the two long side surfaces 110 are respectively provided with mutually cooperating buckles, and the two short side surfaces 120 are flat, the two base plates 100 adjacent to the long side surfaces 110 are buckled and connected through the buckles, and the short side surfaces 120 are staggered with each other, and the base plates adjacent to the short side surfaces are abutted to form a whole floor plane;

[0056] The keel frame 200 has a lower seat 210 fixed to the ground and an upper seat 220 arranged above the lower seat 210, and a cross beam 230 overlapped between the upper seats 220, and the wooden floor plane is laid on the cross beam 230;

[0057] The heat-insulating extruded plate 300 is laid between the cross beams 230; the heat-insulating extruded plate is an XPS extruded plate, and the thickness is 20-30mm, the gap between the cross beams is filled with XPS extruded plate, and the plate joint is sealed with aluminum foil tape, the heat-insulating extruded plate does not directly contact with the base plate, avoiding interference with the engagement between the floor plane and the cross beam support, and in some preferred embodiments, a PE moisture-proof film with a thickness of 0.2mm is pasted on the bottom surface of the XPS extruded plate, further preventing ground moisture penetration;

[0058] The upper seat 220 has an upper contact surface 221, which is provided with a cone group. The cone group includes a plurality of equally spaced protrusions 222. The lower seat 210 has a lower contact surface 211, which is provided with a groove group. The groove group includes a plurality of equally spaced grooves 212. The protrusions 222 are in contact with the grooves 212. The upper contact surface 221 and the lower contact surface 211 are inclined and in contact with each other. The total height of the upper seat 220 and the lower seat 210 after they are in contact is adjusted by the staggered contact of the protrusions 222 and the grooves 212.

[0059] In this embodiment, the two sides of the convex strip 222 are used as support and limiting surfaces to fit against the groove surface of the groove 212, restricting the sliding of the upper fitting surface 221 and the lower fitting surface 211. By different convex strips 222 and grooves 212 being misaligned, the fitting position of the upper seat 220 and the lower seat 210 is changed. Due to the inclined upper fitting surface 221 and the lower fitting surface 211 fitting against each other, the different fitting positions can change the total height of the upper seat 220 and the lower seat 210.

[0060] In some specific embodiments, during the keel height adjustment process, once the height difference value is determined (e.g., 1mm), when the height difference between adjacent protrusions in this technical solution is set to 1mm, it is only necessary to misalign one protrusion or one groove between the upper and lower seats to achieve proper fit. Figure 3 As shown in the middle left section, the protruding strip 222 and the groove 212 are staggered and aligned in one direction, while the upper seat 220 moves and rises 1mm along the inclined mating surface. When the required construction surface base is 1mm higher, the protruding strip 222 and the groove 212 are staggered and aligned in the opposite direction, as shown in the middle left section. Figure 3 As shown in the right-middle section, the upper seat 220 moves and lowers by 1mm along the inclined mating surface. It should be noted that the specific value for raising or lowering is determined by the inclination angle of the upper and lower mating surfaces, as well as the protrusion height or concave depth and spacing of the convex strips or grooves, and is set by technicians based on actual usage. Furthermore, during the adjustment of the keel height, construction personnel should be aware that the mating area between the upper and lower seats should not be too small, such as not less than half or 2 / 3 of the entire mating area. In more specific embodiments, scale lines are marked on the sides of the upper and lower seats corresponding to the convex strips or grooves, or indicators are given indicating the maximum offset position. The specific settings are based on the actual size of the upper and lower seats, and will not be elaborated further in this embodiment.

[0061] Compared with the traditional variable floor, the variable floor provided by the embodiment has a keel frame changing the total height, the upper seat and the lower seat are stably connected through the inclined setting of the upper and lower abutting surfaces, and the upper seat and the lower seat are fixed through the abutting of the convex strip and the groove, so that the total height of the upper seat and the lower seat is changed through the abutting of the convex strip and the groove. Compared with the traditional keel leveling, which needs multiple people to adjust the cushion block and fix it or the traditional screw type adjusting foot which needs multiple rotations to determine the height, the embodiment only needs to select the corresponding convex strip and groove to abut on each other after the height difference is obtained. The variable floor leveling time is greatly reduced, and the operation is simple and convenient, and the work intensity is reduced.

[0062] The traditional screw type adjusting structure relies on the thread to provide vertical support, and has the problems of wear (such as burr of nylon screw hole due to frequent adjustment) leading to locking failure and automatic sliding of the adjusting point. When the load exceeds the design threshold, the adjusting screw may be bent and deformed. The embodiment provides stable support through the abutting of the upper abutting surface and the lower abutting surface, and uses the abutting of the surfaces to provide very strong support in the vertical direction. Meanwhile, the keel frame provided by the embodiment can meet the standard modular production, and the components are separately processed in batches without assembly. The components directly enter the construction site in the form of accessories, and the height adjustment during the construction process is extremely simple. The embodiment has the characteristics of simplifying production to reduce production cost and reducing construction difficulty to improve product competitiveness.

[0063] As shown in FIGS. Figure 1 and Figure 2 In some embodiments, the top surface of the upper seat 220 is provided with a transverse groove 223, the extension direction of the transverse groove 223 is perpendicular to the extension direction of the convex strip 222 and penetrates 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 surface of the two side surfaces of the transverse groove 223, and the top surface of the two side surfaces of the transverse groove 223 is provided with a notch 225 for placing a heat insulation plate support strip 310.

[0064] In the embodiment, the cross beam and the upper seat are stably overlapped in the upper seat through the transverse groove, the structure stability of the whole keel frame is enhanced, the top surface of the cross beam is higher than or flush with the top surface of the upper seat, the wood floor plane can be directly contacted with the cross beam, which is beneficial to the uniform distribution of the load, and the two side surfaces of the transverse groove are used for receiving the heat insulation extruded plate. Since the top surface of the two side surfaces of the transverse groove is leveled through the dislocation of the convex strip and the groove, the laying of the heat insulation extruded plate is also very flat, the notch is used for placing the heat insulation plate support strip for supporting the heat insulation extruded plate, which effectively prevents sagging and protects the level of the heat insulation extruded plate.

[0065] Compared with the traditional keel under the laying of XPS plate to achieve heat insulation, the XPS plate is depressed due to local pressure, resulting in a decrease in the flatness of the floor surface (height difference > 5mm / 2m), affecting the walking comfort. The embodiment adopts the setting of the heat insulation extruded plate between the cross beams, and is supported by the top surface of the two side parts of the horizontal groove and the heat insulation plate support strip, without bearing the load of the keel. The heat insulation extruded plate is mainly used for filling, heat preservation and heat insulation. In this embodiment, the thickness of the heat insulation extruded plate is lower than the height of the top surface of the protruding upper seat of the cross beam, which does not need to bear the load of the base plate, and avoids creep under long-term load.

[0066] As can be understood by those skilled in the art, the upper seat and the lower seat form a keel seat supporting the cross beam. Since the horizontal groove is arranged through, the keel seat can be evenly distributed in the middle of the cross beam, or can be arranged at the end position where the two cross beams meet (as shown in the left part of the keel seat supporting two cross beams). Figure 1 When the keel seat supports the end part where the two cross beams meet, the specific position of the keel seat supported by the cross beam is determined according to the actual construction site, and the embodiment does not need to be described in detail.

[0067] In some specific embodiments, when the keel seat supports the end part where the two cross beams meet, a semicircular groove is formed on the side surface of the cross beam and the horizontal groove in the vertical direction, respectively. The two semicircular grooves form a circular hole, which is fixed by inserting a circular pin, so that the two cross beams are fixed and prevented from being separated, further improving the structural stability of the keel frame.

[0068] As shown in Figure 1 and Figure 4 and Figure 5 In some embodiments, the bottom surface of the base plate 100 is provided with two groove groups 130 in the middle and a single groove group adjacent to the short side surface 120. The column direction of the groove group 130 is parallel to the short side surface 120, the distance between the single groove group and the short side surface 120 is 1 / 2 of the column distance X between the two groove groups, the groove group has equidistantly distributed first groove bodies 131, and the distance between the first groove body 131 and the long edge of the bottom surface of the base plate 100 is 1 / 2 of the row distance Y between adjacent first groove bodies 131.

[0069] The top surface of the cross beam 230 is provided with second groove bodies 231, the second groove bodies 231 are arranged in two columns with a column distance X, the column direction is arranged along the extension direction of the cross beam 230, and each column of second groove bodies 231 is equidistantly arranged with the row distance Y.

[0070] The first groove body 131 and the second groove body 231 are connected by a pin column 232.

[0071] In the present embodiment, the engagement structure is constructed by the first groove, the second groove and the pin column to limit the sliding or displacement of the floor plane in the horizontal direction (such as the transverse direction and the longitudinal direction), and to offset the stress through the engagement structure when the base plate slightly expands or shrinks due to the change of the environmental humidity, thereby avoiding the problems such as the movement and the arching. The stepping force can be dispersed to the keel through the uniform distribution of the multiple points, thereby reducing the local pressure. The engagement structure can significantly improve the overall bearing performance when the base plate is laid in the area with large human flow (such as the corridor, the living room and the shopping mall) or has large self-weight. In some specific embodiments, the waterproof glue or the rubber gasket is applied at the contact position between the pin column and the first groove or the second groove, so as to prevent the moisture from penetrating into the wood to cause the expansion and deformation of the wood.

[0072] As shown in Figure 4 and Figure 5 , in some embodiments, the bottom surface of the base plate 100 is provided with a slot 140, the slot 140 is arranged through the short side surface 120 on both sides, and the slot 140 passes through the center of the first groove 131. The slot depth of the slot 140 is less than the groove depth of the first groove 131.

[0073] When the wood expands due to the moisture or shrinks due to the dryness, the slot of the present embodiment serves as a preset expansion joint to allow the base plate to slightly deform, thereby avoiding the overall arching or cracking. In the present embodiment, the direction of the slot is consistent with the fiber direction of the wood (parallel to the length of the base plate), the stress is concentrated in the slot area by using the transverse elastic deformation capacity of the wood, and the main structure of the base plate is protected. The slot allows the base plate to have a slight expansion space when the humidity changes by cooperating with the first groove, thereby avoiding the cracking of the floor due to the stress concentration.

[0074] As shown in Figure 2 , in some embodiments, the extension direction of the convex strip 222 is parallel to the first side surface 224 of the upper seat 220, the two end surfaces of the convex strip 222 in the extension direction are reserved with the fitting space of the upper fitting surface 221 and the lower fitting surface 211 between the boundaries of the upper fitting surface 221, and the distance between the first side surface 224 of the upper seat 220 and the closest convex strip 222 is less than the interval between the adjacent convex strips 222.

[0075] In the present embodiment, the distance between the first side surface and the closest convex strip is less than the interval between the adjacent convex strips, which can effectively ensure that the edge convex strip can be away from the lower fitting surface when the convex strip and the groove are misaligned, thereby avoiding affecting the fitting between the upper fitting surface and the lower fitting surface. The fitting space is reserved between the boundary of the convex strip and the upper fitting surface, which further improves the fitting stability of the upper and lower fitting surfaces, increases the fitting area, and provides stable support in the vertical direction after the upper seat and the lower seat are fitted.

[0076] In some embodiments, the end face shape of the convex strip or the groove is triangular or trapezoidal. The triangular or trapezoidal end face shape provides two-sided support surfaces and limiting surfaces for the convex strip or the groove, preferably the end face shape of an isosceles triangle or an isosceles trapezoid, the two side surfaces of the convex strip are in surface-to-surface fit with the two side groove surfaces of the groove. Compared with the traditional screw type adjusting structure, the surface-to-surface fit provides more stable support and limiting.

[0077] As Figure 2 In some embodiments, the side bottom of the lower seat 210 is provided with a triangular support part 213, which is arranged 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 part effectively enhances the horizontal stability and enhances the anti-overturning ability by using the stability of the right-angled triangle. At the same time, the triangular support part can provide construction space for the fixed connection between the lower seat and the ground base layer. By setting a counterbore in the triangular support part and setting a fixed locking pin in the counterbore to act on the ground base layer, in some specific embodiments, the triangular support part can also be set as a right-angled support part without a bevel, and the bottom edge surface of the direct support part is fixed to the ground base layer by setting a locking pin, an explosive bolt or the like.

[0078] On the other hand, the present application provides a substrate turning processing method, referring to Figure 4 and Figure 6 , comprising the following steps:

[0079] The feeding process: the transmission belt 410 receives the semi-finished wood board 400 of the previous process, which is a wood board strip that has completed the lock catch process on the long side surface and the top surface covering layer process, and is coarsely cut into a substrate I with a predetermined substrate length. The substrate I is directly coarsely cut into the transmission belt 410 and is arranged flat with the front face upward;

[0080] The turning process: the guide side plate 420 is arranged on both sides of the transmission belt 410 to adjust the posture of the substrate I during conveying, so that the short side surface of the substrate I is flush with the guide side plate 420, and enters the turning station 430. The lifting turntable 440 is arranged at the ends of the transmission belt 410 on both sides, the outer contour of the lifting turntable 440 is provided with a cutting position 441, and the middle part of the end of the transmission belt 410 is provided with a compression belt 450. When the substrate I moves to contact the compression belt 450, the cutting position 441 of the lifting turntable 410 pushes the substrate I away from the transmission belt 410 and moves along the extension direction of the compression belt 450. Then the substrate I is compressed on the cutting position 441 by the compression belt 450 and does lifting and turning movement with the rotation of the lifting turntable 440;

[0081] Cutting process: two saw discs 460 are arranged at the front end of the lifting turntable 440, and the two saw discs 460 are arranged at a fixed interval outside the lifting turntable 440. The two ends of the base plate one are cut by the two saw discs 460 on the two sides in the lifting and turning movement, and the base plate two with a precise length to be processed on the back is obtained. The lifting turntable 440 continues to rotate to move the base plate two to the top. A conveying belt 470 is arranged at the top of the lifting turntable 440. The base plate two enters the conveying belt 470 under the pushing of the cutting position 441;

[0082] Back process: the base plate two is received by the conveying belt 470 and conveyed into a milling groove station. The back of the base plate two is processed into a first groove body 131 and a groove opening 140 based on the short side surface 120 obtained by precise cutting, so that the finished product base plate 100 as shown in Figure 4 is obtained.

[0083] In the embodiment, the semi-finished wood board has completed the processing of the pre-process before falling into the conveying belt, such as the locking process of the long side surface, the setting process of the dovetail in the base plate, the top surface covering process, and the rough cutting process of the wood strip with a pre-set base plate length. It should be noted that the above pre-process can be realized by using the existing process. Therefore, the back process of the base plate between the semi-finished wood board and the finished product base plate also needs to be processed (the back process is the processing of the bottom surface structure of the base plate in the above embodiment). In the traditional technical solution, the semi-finished wood board obtained by the pre-process is obtained by cutting the wood strip produced in a strip. In the embodiment, the conveying belt is arranged to connect the semi-finished wood board obtained by the cutting process, that is, the base plate one. After rough cutting, the base plate one is directly placed on the conveying belt with the front surface upward.

[0084] In the embodiment, the base plate one is turned over by the turning process, and the short side surface of the base plate one is cut during the turning process. The length of the base plate one is ensured to be accurate, and then the short side surface obtained by the cutting process is used as the reference for the back process, thereby providing a precise processing coordinate system for the back process.

[0085] The traditional wood cutting needs to separately arrange a cutting station before and after the turning process, so that the material needs to be positioned and transported for multiple times. In the embodiment, the lifting turntable and the saw disc are cooperatively moved, so that the base plate one synchronously completes the spatial posture adjustment and the end cutting in a single lifting action, and the physical interval between the cutting process and the turning process in the traditional process is eliminated. The embodiment realizes the space-time overlap of the turning and cutting processes of the base plate one, reduces the number of material turnovers, and shortens the processing period of a single workpiece. After the cutting action is embedded in the turning process, the positioning device of the cutting station does not need to be additionally arranged, and the cutting position is directly determined by the rotation path of the lifting turntable, thereby improving the processing precision and the equipment utilization rate.

[0086] In some specific embodiments, as shown in Figure 6As shown, the lifting turntable 440 is a ratchet-like rotating structure, and the outer profile is provided with a cutting position 441, which includes a rear side 4411 for pushing the substrate 1 to move, and a support surface 4412 for contacting the top surface of the substrate 1. When the lifting turntable 440 rotates to the turnover station 430, the rear side 4411 is used to push the rear side of the substrate 1, so that the substrate 1 moves forward under the force, and at the same time, since the compression belt 450 is inclined at this position, the substrate 1 starts to move upward along the compression belt 450, until it contacts the support surface 4412 of the lifting turntable 440. The compression belt 450 is an elastic belt (the position relationship and structure of the compression belt are described in detail in some embodiments below), and at this time, the substrate 1 is pressed on the support surface 4412 by the compression belt 450, and the lifting turntable 440 rotates to lift and turn over.

[0087] It should be noted that a sensor is provided before the substrate 1 enters the turnover station, which is used to control the rhythm of the substrate 1 entering the turnover station. It can be realized by controlling the rotating state of the transmission belt or setting the rotating parameters of the lifting turntable and the lifting turntable, so as to avoid the interference caused by the abutment of the cutting position on the top surface of the substrate 1 when the cutting position rotates to the top surface height of the substrate 1. In actual production, the circumferential rotating distance of the lifting turntable and the gap of the substrate 1 entering the turnover station can avoid the interference between the substrate 1 and the lifting turntable. The skilled person can set it according to the actual production situation, the size and running speed of the equipment, and the means of the prior art. Here, it is not necessary to describe it too much.

[0088] In some preferred embodiments, the cutting position is provided with a support plate for increasing the support surface receiving area on the support surface. The support plate is fixed in the inner side of the lifting turntable by a locking member, so as to avoid interference with the saw disc provided on the outer side. The support plate increases the contact area with the substrate 1, effectively improving the stability of the cutting of the substrate 1 in the lifting and turning movement.

[0089] In some specific embodiments, as shown in Figure 6 As shown, the compression belt 450 is arranged between the two transmission belts 410, i.e. between the two lifting turntables 440. The compression belt 450 is connected by four groups of wheels, wherein the first wheel group 451 is arranged below the lifting turntable 440 at a middle position and is lower than the position of the substrate 1 on the transmission belt 410, the second wheel group 452 is arranged above the lifting turntable 440 at a middle position, the third wheel group 453 and the fourth wheel group 454 are arranged in front of the lifting turntable 440, and the compression belt 450 is sleeved on all the wheel groups to form an elastic belt in a closed loop. The elastic belt between the first wheel group 451 and the second wheel group 452 is pressed between the two lifting turntables 440 and abuts on the connecting rod 442, which is a structure connecting the two lifting turntables 440 and is distributed in the circumferential direction of the shaft of the lifting turntable 440.

[0090] When the substrate one is conveyed to the contact pressure belt by the conveying belt, the substrate one is stopped at the intersection of the pressure belt and the conveying belt because the first wheel group is installed lower than the bearing surface of the conveying belt. At this time, the lifting turntable is rotated, and the rear side of the cutting position pushes the rear side of the board. The pressure belt forms an upwardly inclined running path between the first wheel group and the lifting turntable, and guides the substrate one to move along the path. When the rear side pushes the substrate one to move, the substrate one is already in the support surface. With the rotation of the lifting turntable, the pressure belt continuously presses the substrate one in the support surface, and the substrate one rotates with the lifting turntable to perform the lifting and turning movement.

[0091] In some embodiments, the cutting process comprises:

[0092] In the process of lifting and turning the substrate one after cutting and approaching the top, the pressure belt starts to separate from the substrate two because the position of the cutting position is changed from above the substrate one to below the substrate two. At this time, the substrate two is received by the cutting position, which moves the substrate two to the top under the continuous rotation of the lifting turntable and pushes it into the conveying belt.

[0093] In this embodiment, when the substrate one rotates to the saw disc cutting area, the two end overhanging parts are synchronously cut by the high-speed rotating saw disc to obtain the short side surfaces on both sides. The substrate two after cutting continues to rotate to the top and separates from the cutting position to enter the conveying belt. At this position, the pressure belt no longer presses the substrate two due to the position relationship of the second wheel group, and the support surface changes from facing downward to facing upward and tends to be horizontal after rotation, which can support the substrate two. The substrate two on the support surface is pushed into the conveying belt by the pushing action of the rear side. In the whole process, the substrate one automatically enters the lifting turntable along the conveying belt and is pressed by the pressure belt to perform the lifting and turning movement. The substrate two after lifting has space below, which is convenient for the wood chips and waste to be discharged. The wood chips generated during cutting can naturally fall under the action of gravity, avoiding the accumulation of wood chips in the cutting area, affecting the cutting effect and tool life, and also being conducive to keeping the working environment clean. In actual production, a machine cover is arranged in the space where the saw disc is located to prevent wood chips from splashing.

[0094] In some embodiments, the back surface process comprises:

[0095] When the second substrate enters the milling groove station, the second substrate is positioned, taking the short side surface as the reference of X direction and the long side surface as the reference of Y direction, to build the processing coordinate system of the first groove body and the notch on the back surface of the second substrate, and the back surface of the second substrate is precisely milled through the processing coordinate system to obtain the finished substrate. The finished substrate has the first groove body with accurate size, and the occlusion structure is built through the first groove body, the second groove body of the cross beam and the pin column to limit the sliding or displacement of the substrate in the horizontal direction (such as the transverse direction and the longitudinal direction), and the stress is offset through the occlusion structure when the substrate slightly expands or shrinks due to the change of environmental humidity to avoid problems such as running, arching and the like.

[0096] The preferred embodiments of the present application are specifically described above, but the present application is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
