Description

Technical Field

[0001] This invention relates to the field of building materials technology, and in particular to an automatic drilling and locking device for the core of a double-layer round bamboo floorboard and its manufacturing process. Background Technology

[0002] With increasing global demands for low-carbon emission reduction in the construction industry, round bamboo, as a renewable green building material, is gradually becoming an important alternative to traditional high-energy-consuming building materials such as steel bars and cement, thanks to its advantages such as short growth cycle, high tensile strength along the grain, and low carbon footprint. Against this backdrop, bamboo floor slabs, with round bamboo and reconstituted bamboo as core raw materials, are receiving increasing attention from the construction industry due to their excellent mechanical properties and low-carbon environmental characteristics. Double-layer round bamboo floor slabs are the core load-bearing components in prefabricated bamboo buildings. Their core structure typically consists of a floor slab frame and multiple raw bamboo groups, specifically including two side support plates and multiple layers of bamboo evenly spaced between the two side support plates. Each partition and side support plate is fixedly connected to multiple partitions by nails (such as air gun nails). Multiple raw bamboo assemblies are set inside the floor frame and arranged alternately with the partitions. During the assembly process, multiple raw bamboo assemblies need to be inserted into the floor frame in sequence. Then, through locking holes are drilled on the side support plates, partitions and raw bamboo. Finally, long bolts are inserted to securely lock the raw bamboo in the floor frame, completing the assembly of the double-layer round bamboo floor. Currently, the above processing and assembly procedures are mostly completed manually with simple tools. That is, the raw bamboo is first hammered into the floor frame one by one by the manual laborer, then holes are drilled in the bamboo floor one by one by the hand-held electric drill, and finally bolts are inserted to lock and fix it. However, the above-mentioned existing processing methods have certain shortcomings in actual production: First, the method of manually hammering in the raw bamboo is not only time-consuming and labor-intensive, but also the raw bamboo is prone to skewing, jamming or surface damage due to uneven force during the insertion process, which affects the matching accuracy between the raw bamboo and the floor frame and the subsequent drilling positioning accuracy. Second, the method of drilling holes one by one with a handheld electric drill relies on manual drawing and visual alignment, making it difficult to ensure the consistency of the hole position. Problems such as hole position deviation or hole shaft tilting are prone to occur, which makes it impossible to insert long bolts smoothly, and may even cause the raw bamboo or side support plate to crack and be scrapped, resulting in a low processing yield. To address the aforementioned problems, this invention proposes an automatic drilling and locking device for the core of a double-layer round bamboo floorboard and its manufacturing process. Summary of the Invention

[0003] This invention provides an automatic drilling and locking device and its production process for double-layer round bamboo floorboard cores, which solves the problems of low efficiency, easy deviation, and poor consistency of hand-held drilling hole positions in the existing bamboo floorboard processing.

[0004] This invention provides the following technical solution: An automatic drilling and locking device for a double-layer round bamboo floorboard core is used for drilling holes in the bamboo floorboard. The bamboo floorboard includes a floorboard frame and multiple raw bamboo groups. The floorboard frame includes two side support plates and multiple partitions. The partitions are evenly spaced between the two side support plates and are fixedly connected to the partitions by nails. The multiple raw bamboo groups are all arranged inside the floorboard frame and are staggered with the partitions. Each raw bamboo group includes four raw bamboos tied together. The device includes a base frame, a device frame fixedly installed on the top of the base frame, and a support bridge fixedly installed on the top of the device frame. Multiple moving holes are evenly spaced on the inner wall of the top of the support bridge. The device is characterized in that a clamping component is provided inside the device frame for clamping and positioning the bamboo floorboard. The device also includes: A perforating component installed on top of the support cable tray is used to drill holes in the floor slab frame, multiple partitions, and multiple raw bamboo assemblies.

[0005] In one possible design, the clamping component includes two clamping plates symmetrically slidably connected to the inner wall of the bottom of the equipment frame, and four first electric push rods. The four first electric push rods are symmetrically fixedly installed on both sides of the equipment frame. The output shafts of the two first electric push rods on the same side extend into the equipment frame and are fixedly connected to the corresponding clamping plates. The floor frame is located between the two clamping plates, and both clamping plates are used to clamp and position the floor frame.

[0008] In one possible design, two bidirectional screws are symmetrically rotatably connected to the top of the mounting cable tray. Two adjusting nuts are symmetrically threaded on the bidirectional screws, and the two adjusting nuts can move symmetrically towards each other along the axis of the bidirectional screws. Multiple first connecting plates are fixedly installed at equal intervals on one side of the support plate. The top of the first connecting plates passes through the corresponding movable holes and extends to the top of the mounting cable tray. The same adjusting plate is fixedly installed on the top of the multiple first connecting plates. Connecting components are connected to both sides of the adjusting plate. The connecting components are sleeved on the corresponding bidirectional screws and connected to the corresponding adjusting nuts.

[0009] In one possible design, the connecting assembly includes a connecting bracket rotatably connected to an adjusting nut, a stop shaft fixedly installed inside the connecting bracket, and two connecting holes symmetrically opened on the adjusting plate, with the stop shaft passing through the connecting holes and engaging with the adjusting plate in a transmission manner.

[0010] In one possible design, the conveying component includes a support plate disposed on one side of the equipment rack. Two sliding plates are symmetrically fixedly installed on one side of the support plate. Slide rails are fixedly installed on both sides of the equipment rack. The sliding plates slide on the corresponding slide rails. Limiting holes are provided on the support plate. A mounting box is provided on the top of the support plate. A transmission plate is fixedly installed on the bottom of the mounting box. The transmission plate passes through the limiting holes and is slidably connected to the inner wall of the limiting holes. A third electric push rod is fixedly installed on one side of the bottom of the support plate. The output shaft of the third electric push rod is fixedly connected to one side of the transmission plate. A conveying assembly is installed on the top of the mounting box. The conveying assembly is used to convey raw bamboo bundles. It also includes a first support plate fixedly installed on the bottom of one side of the equipment rack. A first conveying hole is provided on the first support plate. A first support wheel is rotatably connected to the bottom of the first support plate. The top of the first support wheel passes through the first conveying hole and extends to the top of the first support plate for rolling support of the floor frame. Two fifth electric push rods are symmetrically fixedly installed on the bottom of the first support plate. The output shafts of the two fifth electric push rods extend to the top of the first support plate and are fixedly connected to the bottom of the support plate.

[0011] In one possible design, the conveying assembly includes two mounting plates symmetrically fixedly mounted on the top of the mounting box. A double-row conveyor wheel is rotatably connected between the two mounting plates. A second drive motor is fixedly mounted on the bottom of one side of the mounting plate.

An adjustment hole is provided on the inner wall of one side of the sliding hole. A connecting strip is fixedly mounted on one side of the movable plate. One side of the connecting strip passes through the corresponding adjustment hole and extends to the outside of the mounting plate. The connecting strip is slidably connected to the inner wall of the mounting plate. A support strip is fixedly mounted on one side of the connecting strip.

The output shaft of the fourth electric push rod extends to the top of the mounting box and is fixedly connected to the bottom of the fixed plate.

[0012] In one possible design, a second support plate is also included, which is fixedly installed at the bottom of the other side of the equipment rack. The second support plate has a second conveying hole, and a second support wheel is rotatably connected to the bottom of the second support plate. The top of the second support wheel passes through the second conveying hole and extends to the top of the second support plate, so as to be able to remove the perforated bamboo floorboards from the other side of the equipment rack.

[0013] A manufacturing process, applied to the automatic drilling and locking device for the core of the aforementioned double-layer round bamboo floorboard, includes the following steps: S1. First, arrange the two side support plates and multiple partitions at a predetermined interval, so that the multiple partitions are evenly spaced between the two side support plates. Then, use an air gun to nail the side support plates and multiple partitions to form a floor frame. Push the nailed floor frame into the equipment rack from one side. During the pushing process, the first support wheel provides rolling support to the bottom of the floor frame to reduce the pushing resistance. Continue to push the floor frame until it is completely inside the equipment rack and located between the two clamping plates. S2. Simultaneously start the four first electric push rods on both sides of the equipment frame. The output shaft of the first electric push rod extends and pushes the two clamping plates close to each other along the bottom inner wall of the equipment frame until the two clamping plates clamp and fix the floor frame from both sides, so that the floor frame remains stable in position and does not move during the subsequent raw bamboo group conveying and drilling process. After clamping is completed, turn off the four first electric push rods. S3. According to the thickness specifications of the bamboo floorboard to be processed, rotate the two double-acting screws. Under the thread transmission action of the double-acting screws and the adjusting nuts, the two adjusting nuts move symmetrically towards each other along the axis of the double-acting screws. The adjusting nuts drive the stop shaft to move through the connecting frame. The stop shaft drives the two adjusting plates to move towards each other through the transmission cooperation with the connecting holes on the adjusting plates. The two adjusting plates drive the two supporting plates to slide symmetrically towards each other along the inner wall of the mounting cable tray through multiple first connecting plates until the positions of multiple milling hole components correspond to the positions of the holes to be drilled on the floorboard frame. In this way, the symmetrical adjustment of the drilling position is completed according to the thickness of the bamboo floorboard. S4. Start the third electric push rod to move the transmission plate, thereby adjusting the position of the double-row conveyor wheels and double-row pressure wheels so that their positions correspond to the position of the floor slab frame. Then, the bamboo group, which is made by binding four bamboo sticks together, is passed between the double-row conveyor wheels and double-row pressure wheels, so that the two bamboo sticks at the bottom contact the double-row conveyor wheels. Start the fourth electric push rod, and the output shaft of the fourth electric push rod retracts. Through the transmission of the fixed plate, two support bars and two connecting bars, the two moving plates are driven to slide down along the sliding hole, so that the double-row pressure wheels move down to press the two bamboo sticks at the top. The bamboo group is stably clamped by the double-row pressure wheels and double-row conveyor wheels. Start the second drive motor, and the output shaft of the second drive motor drives the double-row conveyor wheels to rotate. Under the action of friction between the double-row conveyor wheels and the bamboo sticks, the bamboo group is conveyed into the floor slab frame until the bamboo group passes through the gap between the corresponding partitions and reaches the predetermined position. S5. After the raw bamboo group is transferred, start the two fifth electric push rods to drive the support plate to move longitudinally, adjust the height of the double row of conveying wheels and double row of pressure wheels, and then repeat step S to transfer multiple raw bamboo groups to the floor frame in sequence. S6. After all the raw bamboo groups have been fed, the first drive motor and the second electric push rod in the multiple milling components are started simultaneously. The output shaft of the first drive motor drives the casing to rotate, and the casing drives the drilling cutter to rotate at high speed. The output shaft of the second electric push rod extends and drives the support box and the drilling cutter to move downward. The drilling cutter passes through the corresponding moving holes, multiple partitions and multiple raw bamboo groups in sequence, and drills through locking holes on each component. During the drilling process, the two clamping plates maintain the clamping state on the floor frame. S7. After drilling is completed, the output shaft of the second electric push rod retracts, driving the drilling cutter to move upward and reset. The first drive motor stops running, and the four first electric push rods are started simultaneously. The output shafts of the first electric push rods retract, causing the two clamping plates to move away from each other, releasing the clamping and positioning of the floor slab frame. The drilled bamboo floor slab is then pushed out from the other side of the equipment frame. During the pushing process, the second support roller provides rolling support to the bottom of the bamboo floor slab to reduce the pushing resistance, completing the entire drilling process of the bamboo floor slab. Afterward, multiple long bolts are passed through the designated holes to stably lock multiple raw bamboo groups. Inside the floor slab frame, lightweight foam material is injected into the floor slab frame from both sides of the exposed bamboo assemblies. This foam material fills the gaps between the bamboo assemblies and the floor slab frame, and after curing, it bonds the bamboo assemblies and the floor slab frame together, filling the gaps between them and improving the connection stability. Finally, the ends of the exposed bamboo assemblies on both sides of the floor slab frame are sealed and fixed with two sealing plates, thus fully enclosing the bamboo floor slab to obtain a prefabricated building floor slab.

[0014] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention. Beneficial effects

[0015] 1. By setting up clamping components, two clamping plates are symmetrically slidably connected within the equipment frame, and four first electric push rods are used to synchronously drive the two clamping plates to move closer to each other from both sides, which can stably and reliably clamp and position the floor frame. The clamping components keep the floor frame in a fixed position throughout the entire process of raw bamboo conveying and drilling, effectively avoiding processing errors caused by floor frame movement or offset, significantly improving the accuracy and consistency of drilling position, and ensuring the smooth progress of subsequent long bolt insertion and raw bamboo locking; 2. By setting up a drilling component, two support plates are symmetrically slidably connected within the mounting cable tray. Multiple milling components are installed at equal intervals on the support plates. The symmetrical position adjustment of the support plates and milling components is achieved by using a two-way screw and adjusting nut. The drilling position can be flexibly adjusted according to the different thicknesses of the bamboo floorboards, making it widely applicable. At the same time, each milling component adopts a structure of a first drive motor and a second electric push rod to achieve high-speed rotation and stable feed of the drilling cutter. The drilling efficiency is high and the hole position is accurate. Multiple partitions and raw bamboo can be drilled simultaneously in one clamping, which greatly improves the processing efficiency. 3. By setting up a conveying component, the double-row conveying wheels and double-row pressure rollers are used to clamp four tied raw bamboos, and the raw bamboo groups are automatically conveyed under the drive of the second drive motor. No manual pushing is required, which reduces labor intensity. At the same time, through the cooperation of the third and fifth electric push rods, the position of the conveying component can be adjusted in the horizontal and vertical directions, realizing the automatic feeding of multiple raw bamboo groups in the floor frame one by one, further improving the automation level and production efficiency of the whole machine. This invention integrates clamping and positioning, symmetrical drilling adjustment, and automatic conveying, realizing fully automated processing of drilling and locking of bamboo floorboards. It has high processing accuracy and efficiency, is suitable for the production of bamboo floorboards of different thicknesses and specifications, and has good prospects for promotion and application.

[0018] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0019] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0020] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0021] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0022] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0023] In one embodiment: Refer to Figure 1-11 A drilling and locking device is used for drilling holes in bamboo floorboards. The bamboo floorboard includes a floorboard frame 42 and multiple raw bamboo assemblies. The floorboard frame 42 includes two side support plates 421 and multiple partitions 422. The multiple partitions 422 are equally spaced between the two side support plates 421. The side support plates 421 are fixedly connected to the multiple partitions 422 by nails. The multiple raw bamboo assemblies are all arranged inside the floorboard frame 42, and the multiple raw bamboo assemblies are staggered with the multiple partitions 422. The partitions 422 and the side support plates 421 can support the raw bamboo 43. The raw bamboo assemblies are four raw bamboo 43 tied together. The raw bamboo 43 is made of moso bamboo. The four raw bamboo 43 are arranged in an alternating manner with the large end and the small end, and then the four raw bamboo 43 are tied together to form the raw bamboo assembly.

[0024] The assembly method for bamboo floor slabs is as follows: Four raw bamboo stalks 43 are arranged in an alternating pattern of large and small ends, and then the four raw bamboo stalks 43 are tied together to form a bamboo assembly. The bamboo assembly is then transferred to the floor slab frame 42. After drilling, multiple long bolts are used to connect the bamboo assembly to the floor slab frame 42 through the corresponding holes. Foaming agent is then filled into the floor slab frame 42 to fill the gaps between the floor slab frame 42 and the bamboo assembly, thus fixing both together and producing a prefabricated building floor slab. This effectively solves the problems of heavy weight and poor sound and heat insulation performance of existing prefabricated building floor slabs.

[0025] like Figure 1 and Figure 2 As shown, the drilling locking device includes a base frame 1, with an equipment frame 2 fixedly mounted on top of the base frame 1. Specifically, the base frame 1 and the equipment frame 2 are fixedly connected by welding. Welding has the advantages of high connection strength and stable structure, ensuring that the equipment frame 2 will not loosen or shift during long-term use, providing a stable support foundation for the entire drilling locking device. A support cable tray 5 is fixedly mounted on top of the equipment frame 2, and the equipment frame 2 and the support cable tray 5 are also fixedly connected by welding to ensure the installation stability of the support cable tray 5. Multiple movable holes are evenly spaced on the inner top wall of the support cable tray 5 (i.e., movable holes are set on the inner top wall of the support cable tray 5). A mounting cable tray 6 is fixedly mounted on top of the support cable tray 5, and the support cable tray 5 and the mounting cable tray 6 are fixedly connected by bolts. Bolt connection facilitates the disassembly and replacement of the mounting cable tray 6, which is beneficial for equipment maintenance and repair. Multiple movable holes (not shown in the figure) are evenly spaced on the inner top wall of the mounting cable tray 6.

[0026] like Figure 3As shown, the equipment frame 2 is equipped with clamping components for clamping and positioning the bamboo floorboards. Specifically, the clamping components include two clamping plates 4 symmetrically slidably connected to the inner wall of the bottom of the equipment frame 2, and four first electric push rods 3. Mounting holes (not shown in the figure) are symmetrically opened on both sides of the equipment frame 2. The four first electric push rods 3 are respectively fixedly mounted on the outer walls of both sides of the equipment frame 2 by bolts. Vibration damping pads (not shown in the figure) are provided between the housing of the first electric push rod 3 and the outer wall of the equipment frame 2. The vibration damping pads can effectively absorb the vibration generated by the first electric push rod 3 during operation, reducing the impact of vibration on the equipment frame 2. The output shafts of the two first electric push rods 3 located on the same side extend into the equipment frame 2 through the corresponding mounting holes and are fixedly connected to the corresponding clamping plates 4. Specifically, the output shaft end of the first electric push rod 3 is provided with an external thread (not shown in the figure), and the clamping plate 4 is provided with a threaded hole (not shown in the figure). The output shaft of the first electric push rod 3 is fixedly connected to the clamping plate 4 by a threaded connection, and a locking nut (not shown in the figure) is provided at the connection. The locking nut can prevent the connection between the output shaft and the clamping plate 4 from loosening during use, ensuring the reliability of clamping. The floor slab frame 42 is located between the two clamping plates 4, and both clamping plates 4 are used to clamp and position the floor slab frame 42.

[0027] After the floor slab frame 42 is nailed in place using an air gun, it can be moved into the equipment frame 2. Then, the four first electric push rods 3 on both sides can be activated simultaneously to move the two clamping plates 4 closer together, thereby clamping and positioning the floor slab frame 42. Through the synchronous drive of the four first electric push rods 3, the two clamping plates 4 can apply a uniform clamping force to the floor slab frame 42, preventing the floor slab frame 42 from shifting or deforming due to uneven force. Thus, during the transfer of raw bamboo 43 into the floor slab frame 42 and the subsequent drilling of the bamboo floor slab, the position of the floor slab frame 42 can be kept stable and will not move, effectively improving the accuracy and reliability of the drilling process.

[0028] like Figure 4 and Figure 5As shown, two support plates 7 are symmetrically slidably connected within the mounting cable tray 6. Multiple milling assembly components are evenly spaced on the top of the support plates 7. The bottom of each milling assembly passes through a corresponding movable hole and extends into the supporting cable tray 5. These milling assembly components are used for drilling holes in the side support plate 421, multiple partitions 422, and the raw bamboo 43. Specifically, the milling assembly includes a second electric push rod 8 fixedly mounted on the top of the support plate 7. A through hole (not shown) is provided on the support plate 7. The housing of the second electric push rod 8 is fixedly mounted on the top of the support plate 7 with bolts. The output shaft of the second electric push rod 8 passes through the through hole and the corresponding movable hole on the support plate 7 and extends into the supporting cable tray 5. A support box 9 is fixedly mounted on the output shaft of the second electric push rod 8. Specifically, the output shaft end of the second electric push rod 8 is provided with a connecting flange (not shown in the figure), and the top of the support box 9 is provided with a corresponding connecting flange (not shown in the figure). The two connecting flanges are fixedly connected by bolts, and a sealing gasket (not shown in the figure) is provided between the flange connection surfaces. The sealing gasket can prevent bamboo chips generated during the drilling process from entering the interior of the support box 9 and protect the drive components inside the support box 9.

[0029] like Figure 6 As shown, a mounting bracket 10 is rotatably connected to the bottom opening of the support box 9, and a drilling and milling cutter 11 is fixedly mounted on the mounting bracket 10. Specifically, the mounting bracket 10 is rotatably connected to the bottom opening of the support box 9 via a bearing (not shown in the figure). The inner ring of the bearing is interference-fitted with the mounting bracket 10, and the outer ring of the bearing is interference-fitted with the bottom opening of the support box 9. This connection method ensures that the mounting bracket 10 maintains good coaxiality and stability when rotating at high speed. A first drive motor 12 is fixedly installed on the top inner wall of the support box 9. The housing of the first drive motor 12 is fixedly installed on the top inner wall of the support box 9 by bolts, and the output shaft of the first drive motor 12 is fixedly connected to the top center position of the mounting bracket 10. Specifically, the output shaft of the first drive motor 12 is provided with a keyway (not shown in the figure), and a corresponding keyway (not shown in the figure) is provided at the center of the top of the locator 10. The output shaft of the first drive motor 12 and the locator 10 are fixedly connected by a key connection. The key connection can transmit a large torque, ensuring that the power of the first drive motor 12 can be efficiently and stably transmitted to the locator 10, driving the drilling and milling cutter 11 to rotate at high speed. The top of the support box 9 is provided with heat dissipation holes (not shown in the figure). The heat dissipation holes can dissipate the heat generated by the first drive motor 12 during operation in a timely manner, preventing the motor from overheating and extending the service life of the motor.

[0030] After symmetrically adjusting the positions of the two support plates 7, multiple milling components can be activated simultaneously. The first drive motor 12 and the second electric push rod 8 are activated respectively. During the operation of the first drive motor 12, the drilling cutter 11 rotates at high speed via the clamping seat 10. When the second electric push rod 8 operates, it moves the drilling cutter 11 downwards, causing the milling components to extend downwards and pass through multiple partitions 422 and multiple raw bamboo groups in sequence, thus achieving the drilling process. This allows the drilling cutter 11 to drill holes in multiple partitions 422 and multiple raw bamboo groups. After drilling is completed, multiple long bolts can be easily passed through the designated holes, and multiple raw bamboo groups can be stably locked within the floor frame 42, completing the assembly of the bamboo floorboard.

[0031] like Figure 5 and Figure 7 As shown, two bidirectional screws 15 are symmetrically rotatably connected to the top of the mounting cable tray 6. Specifically, two sets of bearing seats (not shown in the figure) are symmetrically fixedly installed on the top of the mounting cable tray 6. Each set of bearing seats includes two bearing seats, and the two bidirectional screws 15 are rotatably connected between the corresponding two bearing seats. The bidirectional screws 15 and the bearing seats are rotatably connected by bearings (not shown in the figure). The bearings can reduce the frictional resistance when the bidirectional screws 15 rotate, making the adjustment easier and more flexible. Two adjusting nuts 17 are symmetrically threaded on the bidirectional screws 15. The two adjusting nuts 17 can move symmetrically towards each other along the axial direction of the bidirectional screws 15. Multiple first connecting plates 13 are fixedly installed at equal intervals on one side of the support plate 7. Specifically, one end of the first connecting plate 13 is fixedly connected to one side of the support plate 7 by welding, and the top of the first connecting plate 13 passes through the corresponding movable hole and extends to the top of the mounting cable tray 6. The same adjusting plate 14 is fixedly installed on the top of multiple first connecting plates 13. The first connecting plates 13 and the adjusting plate 14 are fixedly connected by welding. The welding connection can ensure the rigidity of the connection between the adjusting plate 14 and the support plate 7, so that the movement of the adjusting plate 14 can be accurately transmitted to the support plate 7.

[0032] like Figure 7As shown, connecting components are connected to both sides of the adjusting plate 14. These connecting components are sleeved on the corresponding bidirectional screws 15 and connected to the corresponding adjusting nuts 17. Specifically, the connecting components include a connecting frame 18 rotatably connected to the adjusting nut 17. An annular groove (not shown) is provided on the outer wall of the adjusting nut 17. One end of the connecting frame 18 has an annular protrusion (not shown) that matches the annular groove. The connecting frame 18 is rotatably connected to the adjusting nut 17 through the engagement of the annular protrusion and the annular groove. This connection method allows the connecting frame 18 to rotate freely relative to the adjusting nut 17, preventing jamming during adjustment. A stop shaft 19 is fixedly installed inside the connecting frame 18, and the stop shaft 19 is fixedly connected to the connecting frame 18 by welding. Two connecting holes (not marked in the figure) are symmetrically opened on the adjusting plate 14. The stop shaft 19 passes through the connecting holes and engages with the adjusting plate 14 in a transmission manner.

[0033] By rotating the two bidirectional screws 15, the two adjusting plates 14 can be driven to move in opposite directions under the threaded transmission with the corresponding four adjusting nuts 17. Specifically, rotating the bidirectional screws 15, under the threaded transmission with the adjusting nuts 17, drives the adjusting nuts 17 to move laterally along the axis of the bidirectional screws 15. At this time, under the transmission cooperation of the connecting frame 18 and the stop shaft 19, the adjusting plates 14 can be moved. Furthermore, under the transmission cooperation of the connecting hole and the stop shaft 19, the connecting hole is an oblong hole (not shown in the figure), and the length direction of the oblong hole is perpendicular to the axis of the bidirectional screws 15. The stop shaft 19 can slide within the oblong hole along the length direction of the oblong hole, so that the transmission between the connecting frame 18 and the adjusting plates 14 has a certain amount of room for movement. This can compensate for the errors generated during installation and processing, making the adjustment of the two support plates 7 smoother and more precise. This allows for symmetrical adjustment of the positions of multiple milling components, so that the drilling position can be adjusted according to the thickness of the bamboo floorboard, thereby facilitating the drilling processing of the bamboo floorboard.

[0034] This application can be used in the field of building materials technology, or in other fields applicable to this application.

The device frame 2 is further equipped with a conveying component for conveying the raw bamboo 43 into the floor slab frame 42.

The inner wall of the groove slides in sliding engagement with the outer wall of the slide rail 20. A wear-resistant bushing (not shown in the figure) is provided inside the groove. The wear-resistant bushing reduces wear between the sliding plate 21 and the slide rail 20, extending its service life.

[0037] like Figure 8 and Figure 11 As shown, a conveying assembly is installed on the top of the mounting box 23 for conveying the raw bamboo 43. Specifically, the conveying assembly includes two mounting plates 26 symmetrically fixedly mounted on the top of the mounting box 23, and the mounting plates 26 are fixedly connected to the mounting box 23 by welding. A common conveyor wheel is rotatably connected between the two mounting plates 26, and the two ends of the conveyor wheel are rotatably connected to the two mounting plates 26 by bearings (not shown in the figure). A second drive motor 27 is fixedly mounted on the bottom side of one of the mounting plates 26, and the housing of the second drive motor 27 is fixedly mounted on the mounting plate 26 by bolts. The output shaft of the second drive motor 27 passes through the corresponding mounting plate 26 and is fixedly connected to one end of the conveyor wheel. The output shaft of the second drive motor 27 and the conveyor wheel are fixedly connected by a key connection, which ensures the reliability of power transmission.

[0038] like Figure 8 and Figure 11 As shown, a sliding hole 29 is provided on the mounting plate 26, and a movable plate 30 is slidably connected within the sliding hole 29, with the movable plate 30 slidingly engaged with the inner wall of the sliding hole 29. A single pressure roller is rotatably connected to both movable plates 30, with both ends of the pressure roller rotatably connected to the two movable plates 30 via bearings (not shown in the figure). The pressure roller engages with a conveyor roller. An adjustment hole 32 is provided on one side of the inner wall of the sliding hole 29. A connecting strip 34 is fixedly installed on one side of the movable plate 30, and the connecting strip 34 is fixedly connected to the movable plate 30 by welding. One side of the connecting strip 34 passes through the corresponding adjustment hole 32 and extends to the outer side of the mounting plate 26, with the connecting strip 34 slidably connected to the inner wall of the mounting plate 26. A support strip 35 is fixedly installed on one side of the connecting strip 34, and the support strip 35 is fixedly connected to the connecting strip 34 by welding. A single fixing plate 33 is fixedly installed at the bottom of both support strips 35, and the support strip 35 is fixedly connected to the fixing plate 33 by welding. A fourth electric actuator 36 is fixedly installed on the bottom inner wall of the mounting box 23. The housing of the fourth electric actuator 36 is fixedly installed on the bottom inner wall of the mounting box 23 by bolts. The output shaft of the fourth electric actuator 36 extends to the top of the mounting box 23 and is fixedly connected to the bottom of the fixing plate 33. A connecting flange (not shown in the figure) is provided at the end of the output shaft of the fourth electric actuator 36, and a corresponding connecting flange (not shown in the figure) is provided at the bottom of the fixing plate 33. The two connecting flanges are fixedly connected by bolts.

[0039] The transmission wheels are a single-row transmission wheel 28 and a double-row transmission wheel 44, and the pressure wheels are a single-row pressure wheel 31 and a double-row pressure wheel 45. In actual use, the single-row transmission wheel 28 and the single-row pressure wheel 31 are used together, and the double-row transmission wheel 44 and the double-row pressure wheel 45 are used together. In this technical solution, when assembling the single-row transmission wheel 28 and the single-row pressure wheel 31, it is for conveying a single bamboo 43. The specific operation steps are as follows: multiple bamboo 43 are passed through the single-row transmission wheel 28 and the single-row pressure wheel 31 in sequence. The fourth electric push rod 36 is activated, and the output shaft of the fourth electric push rod 36 retracts. Through the transmission of the fixed plate 33, the two support bars 35 and the two connecting bars 34, the two moving plates 30 are driven to slide downward along the sliding hole 29, so that the single-row pressure wheel 31 moves downward and presses the bamboo 43 onto the single-row transmission wheel 28. The second drive motor 27 is activated, and the output shaft of the second drive motor 27 drives the single-row pressure wheel 31 to move downward and press the bamboo 43 onto the single-row transmission wheel 28. The single-row conveyor wheel 28 rotates, and under the friction between the single-row conveyor wheel 28 and the raw bamboo 43, the raw bamboo 43 is conveyed into the floor frame 42 until multiple raw bamboo 43 pass through the gap between the corresponding partitions 422 and reach the predetermined position. During the conveying of the raw bamboo 43, the first support wheel 39 continuously provides rolling support to the floor frame 42. After the multiple groups of raw bamboo arranged longitudinally on one side of the floor frame 42 are conveyed, the third electric push rod 25 is activated. The output shaft of the third electric push rod 25 extends or retracts, driving the transmission plate 24 to slide laterally along the limiting hole. The transmission plate 24 drives the installation box 23 and the conveying assembly to move laterally as a whole, so that the conveying assembly is aligned with the installation position of the raw bamboo arranged longitudinally on the other side of the floor frame 42. After the lateral position of the conveying assembly is adjusted, the multiple raw bamboo 43 arranged longitudinally on the other side are conveyed into the floor frame 42 in sequence in the manner described above, completing the feeding of all raw bamboo 43.

[0040] When assembling the double-row conveyor rollers 44 and double-row pressure rollers 45 in this technical solution, the specific steps are as follows: Start the third electric push rod 25 to move the transmission plate 24, thereby adjusting the positions of the double-row conveyor rollers 44 and double-row pressure rollers 45 so that their positions correspond to the positions of the floor slab frame 421. Then, pass the four pre-tied bamboo poles 43 between the double-row conveyor rollers 44 and double-row pressure rollers 45, so that the two lower bamboo poles 43 contact the double-row conveyor rollers 44. Start the fourth electric push rod 36, and the output shaft of the fourth electric push rod 36 retracts. Through the transmission of the fixed plate 33, two support bars 35, and two connecting bars 34, the two moving plates 30 slide downwards along the sliding hole 29, causing the double-row pressure rollers 45 to... The downward movement presses down the two upper bamboo poles 43, so that the four bamboo poles 43 are stably clamped by the double-row pressure rollers 45 and the double-row transmission rollers 44. The second drive motor 27 is started, and the output shaft of the second drive motor 27 drives the double-row transmission rollers 44 to rotate. Under the action of friction between the double-row transmission rollers 44 and the bamboo poles 43, the four bamboo poles 43 are conveyed into the floor frame 42 until the four bamboo poles 43 pass through the gap between the corresponding partitions 422 and reach the predetermined position. After the four bamboo poles 43 are conveyed, the two fifth electric push rods 38 are started to drive the support plate 22 to move longitudinally, and the height of the double-row transmission rollers 44 and the double-row pressure rollers 45 is adjusted. Then, step S4 is repeated to convey multiple bundled bamboo poles 43 into the floor frame 42 in sequence.

[0041] like Figure 1 As shown, a first support plate 37 is fixedly installed on the bottom side of one side of the equipment frame 2, and the first support plate 37 is fixedly connected to the equipment frame 2 by welding. A first conveying hole (not shown in the figure) is opened on the first support plate 37, and a first support wheel 39 is rotatably connected to the bottom of the first support plate 37. The first support wheel 39 is rotatably connected to the bottom of the first support plate 37 through a rotating shaft (not shown in the figure) and a bearing (not shown in the figure). The top of the first support wheel 39 passes through the first conveying hole and extends to the top of the first support plate 37 for rolling support of the floor slab frame 42. Two fifth electric push rods 38 are symmetrically fixedly installed on the bottom of the first support plate 37, and the housings of the fifth electric push rods 38 are fixedly installed on the bottom of the first support plate 37 by bolts. The output shafts of the two fifth electric actuators 38 extend above the first support plate 37 and are fixedly connected to the bottom of the support plate 22. The output shaft ends of the fifth electric actuators 38 are provided with connectors (not shown in the figure), and the bottom of the support plate 22 is provided with corresponding connecting seats (not shown in the figure). The connectors and connecting seats are fixedly connected by pins (not shown in the figure).

[0042] like Figure 2As shown, a second support plate 40 is fixedly installed on the bottom of the other side of the equipment frame 2. The second support plate 40 is fixedly connected to the equipment frame 2 by welding. A second conveying hole (not shown in the figure) is opened on the second support plate 40. A second support wheel 41 is rotatably connected to the bottom of the second support plate 40. The second support wheel 41 is rotatably connected to the bottom of the second support plate 40 through a rotating shaft (not shown in the figure) and a bearing (not shown in the figure). The top of the second support wheel 41 passes through the second conveying hole and extends above the second support plate 40, so as to be able to remove the perforated bamboo floorboard from the other side of the equipment frame 2. The first support wheel 39 and the second support wheel 41 are both made of rubber (not shown in the figure). Rubber has good elasticity and wear resistance, which can support the bamboo floorboard while avoiding scratches on the surface of the bamboo floorboard.

[0043] This invention proposes a production process for use in an automatic drilling and locking device for the core of a double-layer round bamboo floorboard, as described above, comprising the following steps: S1. First, arrange the two side support plates 421 and multiple partition plates 422 at a predetermined interval, so that the multiple partition plates 422 are equally spaced between the two side support plates 421. Then, use an air gun to nail the side support plates 421 and multiple partition plates 422 to form a floor frame 42. Push the nailed floor frame 42 into the equipment rack 2 from one side. During the pushing process, the first support wheel 39 provides rolling support to the bottom of the floor frame 42 to reduce the pushing resistance. Continue to push the floor frame 42 until it is completely inside the equipment rack 2 and located between the two clamping plates 4. S2. Simultaneously start the four first electric push rods 3 on both sides of the equipment frame 2. The output shaft of the first electric push rod 3 extends and pushes the two clamping plates 4 to move closer to each other along the bottom inner wall of the equipment frame 2 until the two clamping plates 4 clamp and fix the floor frame 42 from both sides, so that the floor frame 42 remains stable in position and does not move during the subsequent raw bamboo group conveying and drilling process. After clamping is completed, turn off the four first electric push rods 3. S3. According to the thickness specifications of the bamboo floorboard to be processed, rotate the two double-acting screws 15. Under the thread transmission action of the double-acting screws 15 and the adjusting nuts 17, the two adjusting nuts 17 move symmetrically towards each other along the axial direction of the double-acting screws 15. The adjusting nuts 17 drive the stop shaft 19 to move through the connecting frame 18. The stop shaft 19 drives the two adjusting plates 14 to move towards each other through the transmission cooperation with the connecting holes on the adjusting plate 14. The two adjusting plates 14 respectively drive the two supporting plates 7 to slide symmetrically towards each other along the inner wall of the mounting bridge 6 through multiple first connecting plates 13 until the positions of multiple milling hole components correspond to the positions of the holes to be drilled on the floorboard frame 42. In this way, the symmetrical adjustment of the drilling position is completed according to the thickness of the bamboo floorboard. S4. Activate the third electric push rod 25 to move the transmission plate 24, thereby adjusting the positions of the double-row conveyor rollers 44 and double-row pressure rollers 45 so that their positions correspond to the position of the floor slab frame 421. Then, the raw bamboo bundle passes between the double-row conveyor rollers 44 and double-row pressure rollers 45, so that the two raw bamboos 43 at the bottom contact the double-row conveyor rollers 44. Activate the fourth electric push rod 36, and the output shaft of the fourth electric push rod 36 retracts, passing through the fixed plate 33, two support bars 35, and two connecting... The transmission of strip 34 drives two moving plates 30 to slide downward along the sliding hole 29, causing the double row pressure rollers 45 to move downward and press the two raw bamboos 43 located above, so that the raw bamboo group is stably clamped by the double row pressure rollers 45 and the double row transmission rollers 44. The second drive motor 27 is started, and the output shaft of the second drive motor 27 drives the double row transmission rollers 44 to rotate. Under the action of friction between the double row transmission rollers 44 and the raw bamboos 43, the raw bamboo group is conveyed into the floor frame 42 until the raw bamboo group passes through the gap between the corresponding partitions 422 and reaches the predetermined position. S5. After the raw bamboo group is transferred, the two fifth electric push rods 38 are activated to drive the support plate 22 to move longitudinally, adjust the height of the double-row conveyor wheel 44 and the double-row pressure wheel 45, and then repeat step S4 to transfer multiple raw bamboo groups into the floor frame 42 in sequence. S6. After all the raw bamboo groups have been fed, the first drive motor 12 and the second electric push rod 8 in the multiple milling components are started simultaneously. The output shaft of the first drive motor 12 drives the clasp 10 to rotate, and the clasp 10 drives the drilling cutter 11 to rotate at high speed. The output shaft of the second electric push rod 8 extends out, driving the support box 9 and the drilling cutter 11 to move downward. The drilling cutter 11 passes through the corresponding moving hole, multiple partitions 422 and multiple raw bamboo groups in sequence, and drills through locking holes on each component. During the drilling process, the two clamping plates 4 keep clamped to the floor frame 42. S7. After drilling is completed, the output shaft of the second electric push rod 8 retracts, driving the drilling cutter 11 to move upward and reset. The first drive motor 12 stops running, and the four first electric push rods 3 are started simultaneously. The output shafts of the first electric push rods 3 retract, driving the two clamping plates 4 to move away from each other, releasing the clamping and positioning of the floor slab frame 42, and pushing the drilled bamboo floor slab out from the other side of the equipment frame 2. During the pushing process, the second support roller 41 provides rolling support to the bottom of the bamboo floor slab to reduce the pushing resistance, completing the entire drilling process of the bamboo floor slab. Afterwards, multiple long bolts are passed through the designated holes to stably lock multiple raw bamboo groups onto the floor slab. Within the frame 42, lightweight foam material is injected into the floor slab 42 from both sides of the exposed bamboo assembly. This foam material fills the gaps between the bamboo assembly and the floor slab 42, and after curing, it bonds the bamboo assembly and the floor slab 42 together, filling the gaps between them and improving the connection stability. Finally, the exposed bamboo assembly ends on both sides of the floor slab 42 are sealed and fixed with two sealing plates, thus achieving a fully enclosed bamboo floor slab and obtaining a prefabricated building floor slab.

9. The automatic drilling and locking device for the core of a double-layer round bamboo floor slab according to claim 7, characterized in that, It also includes a second support plate (40) fixedly installed on the bottom of the other side of the equipment rack (2). The second support plate (40) has a second conveying hole. The bottom of the second support plate (40) is rotatably connected to a second support wheel (41). The top of the second support wheel (41) passes through the second conveying hole and extends to the top of the second support plate (40) so that the perforated bamboo floorboard can be moved out from the other side of the equipment rack 2.

10. A production process, applied in the automatic drilling and locking device for the core of a double-layer round bamboo floorboard as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. First, place the two side support plates (421) and multiple partitions (422) at a predetermined interval, so that the multiple partitions (422) are evenly spaced between the two side support plates (421). Then, use an air gun to nail the side support plates (421) and multiple partitions (422) to form a floor frame (42). Push the nailed floor frame (42) into the equipment rack (2) from one side. During the pushing process, the first support wheel (39) provides rolling support to the bottom of the floor frame (42) to reduce the pushing resistance. Continue to push the floor frame (42) until it is completely inside the equipment rack (2) and located between the two clamping plates (4). S2. Simultaneously start the four first electric push rods (3) on both sides of the equipment frame (2). The output shaft of the first electric push rod (3) extends and pushes the two clamping plates (4) to approach each other along the bottom inner wall of the equipment frame (2) until the two clamping plates (4) clamp and fix the floor frame (42) from both sides, so that the floor frame (42) remains stable in position during the subsequent raw bamboo group conveying and drilling process and does not move. After clamping is completed, turn off the four first electric push rods (3). S3. According to the thickness specifications of the bamboo floorboard to be processed, rotate the two double-acting screws (15). Under the thread transmission of the double-acting screws (15) and the adjusting nuts (17), the two adjusting nuts (17) move symmetrically towards each other along the axis of the double-acting screws (15). The adjusting nuts (17) drive the stop shaft (19) to move through the connecting frame (18). The stop shaft (19) drives the two adjusting plates (14) to move towards each other through the transmission cooperation with the connecting hole on the adjusting plate (14). The two adjusting plates (14) respectively drive the two supporting plates (7) to slide symmetrically towards each other along the inner wall of the mounting bridge (6) through multiple first connecting plates (13) until the position of multiple milling hole components corresponds to the position of the hole to be drilled on the floorboard frame (42). In this way, the symmetrical adjustment of the drilling position is completed according to the thickness of the bamboo floorboard. S4. Start the third electric push rod (25) to drive the transmission plate (24) to move, thereby adjusting the position of the double-row conveyor wheel (44) and the double-row pressure wheel (45) so that the position of the double-row conveyor wheel (44) and the double-row pressure wheel (45) corresponds to the position of the floor frame (421). Then, the raw bamboo group passes between the double-row conveyor wheel (44) and the double-row pressure wheel (45) so that the two raw bamboos (43) below contact the double-row conveyor wheel (44). Start the fourth electric push rod (36). The output shaft of the fourth electric push rod (36) retracts and passes through the fixed plate (33), the two support bars (35) and the two connecting rods. The transmission of the connecting strip (34) drives the two moving plates (30) to slide down along the sliding hole (29), causing the double row pressure rollers (45) to move down and press the two raw bamboos (43) located above, so that the raw bamboo group is stably clamped by the double row pressure rollers (45) and the double row transmission rollers (44). The second drive motor (27) is started, and the output shaft of the second drive motor (27) drives the double row transmission rollers (44) to rotate. Under the action of friction between the double row transmission rollers (44) and the raw bamboos (43), the raw bamboo group is conveyed into the floor frame (42) until the raw bamboo group passes through the gap between the corresponding partitions (422) and reaches the predetermined position. S5. After the raw bamboo group is transferred, start the two fifth electric push rods (38) to drive the support plate (22) to move longitudinally, adjust the height of the double row of transfer wheels (44) and double row of pressure wheels (45), and then repeat step S4 to transfer multiple raw bamboo groups to the floor frame (42) in sequence. S6. After all the raw bamboo groups have been fed, the first drive motor (12) and the second electric push rod (8) in the multiple milling components are started simultaneously. The output shaft of the first drive motor (12) drives the card holder (10) to rotate. The card holder (10) drives the drilling cutter (11) to rotate at high speed. The output shaft of the second electric push rod (8) extends out, driving the support box (9) and the drilling cutter (11) to move downward. The drilling cutter (11) passes through the corresponding moving hole, multiple partitions (422) and multiple raw bamboo groups in sequence, drilling through locking holes on each component. During the drilling process, the two clamping plates (4) maintain the clamping state on the floor frame (42). S7. After drilling is completed, the output shaft of the second electric push rod (8) retracts, driving the drilling cutter (11) to move upward and reset. The first drive motor (12) stops running and the four first electric push rods (3) are started simultaneously. The output shaft of the first electric push rod (3) retracts, driving the two clamping plates (4) to move away from each other, releasing the clamping and positioning of the floor slab frame (42), and pushing the drilled bamboo floor slab out from the other side of the equipment frame (2). During the pushing process, the second support wheel (41) provides rolling support to the bottom of the bamboo floor slab to reduce the pushing resistance, completing the entire drilling process of the bamboo floor slab. Afterwards, multiple long bolts are passed through the designated holes to stably lock multiple raw bamboo groups onto the floor. Inside the frame (42), lightweight foam material is injected into the floor frame (42) from both sides of the original bamboo group visible from the floor frame (42) for filling. The foam material fills the interior of the floor frame (42) and fills the gap between the original bamboo group and the floor frame (42). After the foam material is cured, it bonds the original bamboo group and the floor frame (42) together and fills the gap between the original bamboo group and the floor frame (42), improving the connection stability between the original bamboo group and the floor frame (42). Finally, the ends of the original bamboo group visible from both sides of the floor frame (42) are sealed and fixed with two sealing plates, so that the bamboo floor can be fully enclosed to obtain the prefabricated building floor.
