Description

Technical Field

[0001] This invention relates to the field of bamboo processing, and in particular to a sheet-forming device and processing line for a bamboo fiber recombination unit. Background Technology

[0002] In current large-scale production of bamboo fiber composite materials, a process of discretely laying and assembling fibrous recombinant units is commonly used. This method easily leads to uneven distribution of units and poor integrity of preforms, resulting in a series of problems such as large performance dispersion of products, low production efficiency, insufficient material utilization, and high energy consumption, which seriously restricts the continuous and automated production of high-quality bamboo fiber composite materials.

[0003] Currently, weaving equipment for bamboo fiber reconstituted units has largely achieved automation. Mechanical structures or control systems drive weaving tools to complete basic weaving actions such as interlacing and laying the reconstituted units, significantly improving production efficiency and capacity compared to hand weaving. However, existing equipment still has the following problems: Firstly, the large gaps between units in the woven reconstituted unit sheet result in a less compact structure, making it prone to loosening during subsequent drying, gluing, and laying processes, affecting the surface quality and density uniformity of the reconstituted material. Secondly, the overlapping connection positions between adjacent units (i.e., the overlapping parts of the bamboo fiber reconstituted units) are completely random, lacking effective control methods, leading to large fluctuations in product quality and making it difficult to achieve stable and uniform product specifications and performance.

[0004] In summary, there is an urgent need to develop a weaving equipment that can control the overlapping of bamboo fiber recombinant units in order to improve the quality of recombinant material products. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides a sheet-forming device and processing line for bamboo fiber reconstituted units, which solves the problem of large gaps between woven sheet-forming reconstituted units and the inability to accurately control the overlapping process, thereby improving the quality stability of reconstituted material products.

[0006] The technical solution of the present invention is as follows:

[0007] A first aspect of the present invention provides a sheet-forming apparatus for bamboo fiber reconstituted units, the sheet-forming apparatus being used to overlap and weave adjacent bamboo fiber reconstituted units into a continuous sheet-forming reconstituted unit. The sheet-forming apparatus includes:

[0008] frame;

[0009] The feeding and conveying unit, fixed to the frame, is used to convey bamboo fiber reconstituted units. The feeding and conveying unit has multiple parallel first conveyor belts on the rear side of the frame and multiple parallel second conveyor belts on the front side of the frame. The first and second conveyor belts are staggered, and the front end of the first conveyor belt is connected to the rear end of the second conveyor belt. The feeding and conveying unit has a first rotation source and a second rotation source fixed to the frame. The first rotation source drives the first conveyor belt to run continuously, and the second rotation source drives the second conveyor belt to run in a stepping manner.

[0010] The alignment mechanism, fixed to the rear side of the frame, is used to align the bamboo fiber reconstituted units on the first conveyor belt.

[0011] There are at least two pushing mechanisms, which are fixed at intervals to the frame and arranged perpendicular to the conveying direction. Each pushing mechanism is installed between two adjacent first conveyor belts and close to the rear end of the second conveyor belt. The pushing mechanism acts on the bamboo fiber reconstituted unit that crosses the first and second conveyor belts at the same time. The front end of the bamboo fiber reconstituted unit is on the second conveyor belt, and the pushing mechanism lifts the rear end of the bamboo fiber reconstituted unit so that it overlaps the adjacent bamboo fiber reconstituted unit behind it.

[0012] A weaving mechanism, fixed to the front side of the frame, is used to weave the overlapping bamboo fiber reconstituted units located on the second conveyor belt into continuous, sheet-like reconstituted units; and

[0013] The control system is used to control the operation of the first rotation source, the second rotation source, the leveling mechanism, the pushing mechanism, and the weaving mechanism.

[0014] According to the aforementioned sheet-forming device for bamboo fiber recombination unit, the feeding and conveying group is provided with a first rotating shaft, a second rotating shaft, and a fixed shaft arranged in parallel at intervals at the rear end, front end, and middle of the frame. The two ends of the first rotating shaft and the second rotating shaft are rotatably connected to the frame, and the two ends of the fixed shaft are fixedly connected to the frame. The two ends of the first conveyor belt are sleeved on the first rotating shaft and the fixed shaft. The two ends of the second conveyor belt are sleeved on the second rotating shaft and the fixed shaft.

[0015] According to the aforementioned sheet-forming device for bamboo fiber recombination unit, there are two alignment mechanisms, which are spaced apart perpendicular to the conveying direction. Each alignment mechanism is installed between two adjacent first conveyor belts, corresponding to the rear end or middle position of the first conveyor belt. Each alignment mechanism is equipped with a first position sensor and a first linear drive fixedly mounted on the frame. The drive end of the first linear drive is connected to a stop bar, and the extension direction of the stop bar is perpendicular to the horizontal plane of the first conveyor belt. Along the conveying direction, the stop bar is located in front of the first position sensor. The first position sensor and the first linear drive are respectively communicatively connected to the control system.

[0016] According to the aforementioned sheet-forming device for bamboo fiber recombination unit, the pushing mechanism includes a second linear drive fixedly mounted on the frame, a third linear drive slidably connected to the second linear drive, and the second linear drive drives the third linear drive to move back and forth; a push rod is connected to the driving end of the third linear drive, and the third linear drive drives the push rod to move up and down; a second position sensor is fixedly mounted on the third linear drive; along the conveying direction, the push rod is located in front of the second position sensor; the second linear drive, the third linear drive, and the second position sensor are respectively communicatively connected to the control system.

[0017] Furthermore, the bottom end of the push rod is connected to the drive end of the third linear drive unit through the mounting base. The mounting base has an elongated hole, the length of which is along the forward direction of the bamboo fiber reconstituted unit. The bottom end of the push rod is a threaded end. The bottom end of the push rod passes through the elongated hole and is fixed to the mounting base by a nut.

[0018] According to the aforementioned sheet-forming device for bamboo fiber recombination unit, a pressing belt group is fixedly installed on the upper front side of the frame to press the overlapped bamboo fiber recombination unit onto the second conveyor belt.

[0019] The pressing belt assembly includes a third rotation source and multiple third conveyor belts arranged in parallel and spaced apart on the frame. The third conveyor belts are located at the front end of the first conveyor belt and above the second conveyor belt. The third rotation source drives the third conveyor belts to move synchronously with the second conveyor belts. The third rotation source is communicatively connected to the control system.

[0020] A moving space for bamboo fiber recombining units is formed between the third conveyor belt and the second conveyor belt; the bamboo fiber recombining units move in conjunction with the third conveyor belt and the second conveyor belt.

[0021] According to the aforementioned sheet-forming device for bamboo fiber reconstituted units, a pusher mechanism is provided at the rear end of the frame corresponding to the material receiving position of the bamboo fiber reconstituted units, and a side baffle is provided on one side of the frame opposite to the pusher mechanism; the pusher mechanism and the side baffle work together to align the two ends of the bamboo fiber reconstituted units on the feeding conveyor group along their length; the pusher mechanism includes:

[0022] The cylinder drive component is fixed to the rear end of the frame by a bracket;

[0023] The push plate is fixedly connected to the drive end of the cylinder drive component;

[0024] The third position sensor is fixed to the rear end of the frame by a bracket;

[0025] The cylinder drive and the third position sensor are respectively connected to the control system for communication.

[0026] A second aspect of the present invention provides a processing production line. The processing production line includes a feeding conveyor, a receiving device, and the sheet-forming device described in the first aspect of the present invention;

[0027] The feeding conveyor is located upstream of the bamboo fiber reconstitution unit sheet-forming device. The feeding conveyor is used to convey bamboo fiber reconstitution units to the bamboo fiber reconstitution unit sheet-forming device. The feeding conveyor is equipped with a main feeding conveyor, a first feeding conveyor, and a second feeding conveyor. The discharge end of the main feeding conveyor is connected to the feed end of the feeding conveyor group of the bamboo fiber reconstitution unit sheet-forming device. The first feeding conveyor and the second feeding conveyor are arranged side by side, and their discharge ends both face the main feeding conveyor. The first feeding conveyor and the second feeding conveyor alternately feed bamboo fiber reconstitution units to the main feeding conveyor.

[0028] The material collection device is located downstream of the bamboo fiber reconstructing unit and is used to collect the woven reconstructed units.

[0029] Furthermore, the receiving device includes a first discharge conveyor and a winding assembly;

[0030] The first discharge conveyor is located in front of the second conveyor belt and is lower than the second conveyor belt. It is used to convey the whole sheet recombination unit after the winding assembly is rolled forward.

[0031] There are two sets of winding assemblies, located on both sides of the front end of the second conveyor belt and above the first discharge conveyor; the winding assembly includes a slide, on which a rotary drive motor is slidably mounted, and at the output end of the rotary drive motor is a reel; the reels of the two sets of winding assemblies are arranged opposite to each other.

[0032] Furthermore, the receiving device includes a second discharge conveyor, a folding drive assembly, and a receiving tray;

[0035] The receiving tray is used to collect the whole sheet reassembly unit that falls from the sliding roller.

[0036] The sheet-forming device and processing line for bamboo fiber recombination units provided by this invention have at least the following advantages compared with the prior art:

[0037] (1) The integral sheet device of the present invention realizes the forward movement of the recombining unit through two front and rear conveyor belts, and realizes the overlap of two adjacent recombining units at the junction of the two conveyor belts, thereby realizing the controllable overlap of the recombining units; and the overlapping bamboo fiber recombining units are woven into integral sheet recombining units by the weaving mechanism, thereby improving the quality stability of the recombining material products.

[0038] (2) The integral sheet forming device of the present invention has a clear process decomposition, precise mechanical timing coordination, and realizes fully automated control, ensuring the continuity of the bamboo fiber recombination unit overlapping process and guaranteeing product quality. The entire overlapping process eliminates manual operation links, greatly reduces the number of operators required, lowers the labor costs of enterprises, and improves the working environment and employee safety and health conditions.

[0073] To make the technical problem to be solved, the technical solution and advantages of the present invention clearer, the following description will be provided in conjunction with the accompanying drawings. Figures 1 to 18 The technical solution of the present invention will be clearly and completely described in conjunction with specific embodiments.

[0074] The bamboo fiber reconstructed unit 200 is a bamboo fiber veneer before weaving, which can also be referred to as "reconstructed unit" in the following text; the whole sheet reconstructed unit is a continuous bamboo curtain formed by weaving multiple bamboo fiber veneers.

[0075] Example 1:

[0076] This invention provides a sheet-forming device for bamboo fiber reconstructing units. The sheet-forming device is used to form an overlapping connection between two adjacent bamboo fiber reconstructing units and weave them into a continuous sheet-forming reconstructing unit.

[0077] 100 sheets of equipment Figures 1 to 5 As shown, the sheet forming device 100 includes a frame 110, a feeding and conveying group 120, a straightening mechanism 130, a pushing mechanism 140, and a weaving mechanism 150.

[0078] The frame 110 supports other components mounted thereon. A feeding conveyor assembly 120 is fixed to the frame 110 and is used to convey the bamboo fiber reconstituted unit 200. The feeding conveyor assembly 120 has multiple parallel first conveyor belts 121 on the rear side of the frame 110 and multiple parallel second conveyor belts 122 on the front side of the frame 110. The first conveyor belts 121 and second conveyor belts 122 are staggered, and the front end of the first conveyor belt 121 connects to the rear end of the second conveyor belt 122. The feeding conveyor assembly 120 has a first rotation source 123 and a second rotation source 124 fixed to the frame 110. The first rotation source 123 drives the first conveyor belt 121 to run continuously, and the second rotation source 124 drives the second conveyor belt 122 to run in a stepping manner. The second conveyor belt 122 is driven by a cam mechanism or pneumatic actuator, typically driven by the second rotation source 124, causing it to cycle through a "stop-forward-stop" motion at a preset step length. Within each conveying cycle, the bamboo fiber reconstituted unit 200 is advanced a fixed distance and then stops, allowing time for the next operation of the weaving mechanism 150. The step length of the second conveyor belt 122 should match the width of the bamboo fiber reconstituted unit 200 and the weaving density of the final integral reconstituted unit. By adjusting the step length, the warp density of the final product can be controlled.

[0079] The first rotation source 123 and the second rotation source 124 can be selected as devices capable of outputting rotation, such as a motor, an engine, a hydraulic motor, or a combination of one of them and a reducer. Preferably, the first rotation source 123 and the second rotation source 124 are a combination of a motor and a reducer, which converts electrical energy into mechanical energy through reasonable matching.

[0080] The alignment mechanism 130 is fixed to the rear side of the frame 110 and is used to align the bamboo fiber reconstructed unit 200 on the first conveyor belt 121 to ensure that two adjacent bamboo fiber reconstructed units 200 form an effective overlap in the subsequent process.

[0081] The bamboo fiber reconstituted unit sheet forming device 100 includes at least two pushing mechanisms 140, which are fixedly spaced on the frame 110 and perpendicular to the conveying direction. Each pushing mechanism 140 is installed between two adjacent first conveyor belts 121 and near the rear end of the second conveyor belt 122. The pushing mechanism 140 acts on the rear end portion of the bamboo fiber reconstituted unit 200 that simultaneously crosses the first conveyor belt 121 and the second conveyor belt 122. In this embodiment of the invention, two pushing mechanisms 140 are used. The specific number of pushing mechanisms 140 can be selected according to the actual situation to ensure that the side end of the bamboo fiber reconstituted unit 200 is lifted.

[0082] The weaving mechanism 150 is fixed to the front side of the frame 110. The weaving mechanism 150 is used to weave the overlapping bamboo fiber reconstituted units 200 located on the second conveyor belt 122 into continuous, integral reconstituted units. The weaving mechanism 150 is prior art and not a key technical point of this invention; therefore, it will not be described in detail in this embodiment. The forward conveying frequency of the second conveyor belt 122 is coordinated with the weaving frequency of the weaving mechanism 150. The second conveyor belt 122 and the weaving mechanism 150 are synchronized in time through a unified controller. When the second conveyor belt 122 completes one conveying cycle (i.e., advances one step), the weaving mechanism 150 completes one round of weaving, forming a closed-loop working mode of alternating "conveyor-weaving".

[0083] The control system is used to control the operation of the first rotation source 123, the second rotation source 124, the straightening mechanism 130, the pushing mechanism 140 and the weaving mechanism 150.

[0084] The bamboo fiber reconstituted unit integral sheet device of this invention uses two conveyor belts to advance the reconstituted units, and overlaps adjacent reconstituted units at the junction of the two conveyor belts. A pushing mechanism lifts the preceding reconstituted unit, and the following adjacent reconstituted unit is conveyed via a feeding conveyor to the area below the lifted reconstituted unit, thus overlapping the two adjacent reconstituted units. The overlapped reconstituted units are then woven into a continuous integral sheet reconstituted unit by a weaving mechanism.

[0085] When the front end of the bamboo fiber reconstituted unit 200 is on the second conveyor belt 122, the second conveyor belt 122 stops moving, and the pushing mechanism 140 lifts the rear end of the bamboo fiber reconstituted unit 200, causing it to tilt upwards away from the surface of the first conveyor belt 121. The adjacent bamboo fiber reconstituted unit 200 continues to move forward under the drive of the first conveyor belt 121, its front end gradually approaching and eventually positioned below the lifted front bamboo fiber reconstituted unit 200, achieving an overlap between the two adjacent bamboo fiber reconstituted units 200. After the overlap is completed, the second conveyor belt 122 resumes movement, conveying the overlapped multi-layer bamboo fiber reconstituted units 200 forward, where the weaving mechanism 150 weaves the overlapped bamboo fiber reconstituted units 200 into a continuous, sheet-like reconstituted unit.

[0086] The sheet-forming device of this invention, through the coordinated operation of two conveyor belts (continuous conveying of the first conveyor belt 121 and intermittent conveying of the second conveyor belt 122) and the precise control of the pushing mechanism 140, enables the bamboo fiber recombination unit 200 to automatically and accurately complete the interlayer overlap, avoiding the deviation of manual stacking, ensuring the neatness and stability of the stack, and improving the consistency of product quality.

[0087] The feeding and conveying assembly 120 is provided with a first rotating shaft 125, a second rotating shaft 126, and a fixed shaft 127 arranged parallel to each other at the rear, front, and middle of the frame 110. The two ends of the first rotating shaft 125 and the second rotating shaft 126 are rotatably connected to the frame 110, and the two ends of the fixed shaft 127 are fixedly connected to the frame 110. The two ends of the first conveyor belt 121 are fitted onto the first rotating shaft 125 and the fixed shaft 127; the two ends of the second conveyor belt 122 are fitted onto the second rotating shaft 126 and the fixed shaft 127. A bearing is provided on the fixed shaft 127. The inner ring of the bearing is fixedly connected to the fixed shaft, and the outer ring of the bearing is rotatably connected to the first conveyor belt 121. One end of the first conveyor belt 121 is fitted onto the bearing. A roller is provided on the first rotating shaft 125, rotating synchronously with the first rotating shaft. The other end of the first conveyor belt 121 is fitted onto the roller. The second conveyor belt 122 also adopts the same connection structure as the first conveyor belt 121, which will not be described further here.

[0088] The two sets of conveyor belts (first conveyor belt 121 and second conveyor belt 122) are staggered and form a compact conveying unit through a common shaft (fixed shaft 127), which improves space utilization and makes the entire material feeding and conveying group 120 occupy a more compact space, making it easier to integrate.

[0089] Two alignment mechanisms 130 are arranged at intervals perpendicular to the conveying direction. Each alignment mechanism 130 is installed between two adjacent first conveyor belts 121, corresponding to the rear end or middle position of the first conveyor belt 121. The symmetrically arranged alignment mechanisms 130 on both sides achieve precise alignment and straightening of the bamboo fiber recombination unit 200. Each alignment mechanism 130 is equipped with a first position sensor 131 and a first linear drive 132 fixedly mounted on the frame 110. The drive end of the first linear drive 132 is connected to a stop bar 133, the extension direction of which is perpendicular to the horizontal plane of the first conveyor belt 121. Along the conveying direction, the stop bar 133 is located in front of the first position sensor 131. The first position sensor 131 and the first linear drive 132 are communicatively connected to the control system. The first position sensor 131 detects the arrival status of the bamboo fiber recombination unit 200 in real time, identifies the position information of both ends of the bamboo fiber recombination unit 200, and provides trigger signals to the control system. The first linear drive 132 drives the stop lever 133 to move up and down, thereby blocking and releasing the bamboo fiber reconstructed unit 200 on the first conveyor belt 121: when the first linear drive 132 drives the stop lever 133 to rise, the stop lever 133 blocks the bamboo fiber reconstructed unit 200 from continuing to move forward on the first conveyor belt 121; when the first linear drive 132 drives the stop lever 133 to fall, the bamboo fiber reconstructed unit 200 continues to move forward on the first conveyor belt 121.

[0090] The first position sensor 131 is a photoelectric sensor or a proximity sensor. The first linear drive 132 is a hydraulic cylinder, a pneumatic cylinder, or an electric linear actuator.

[0091] When the bamboo fiber reconstituted unit 200 on the first conveyor belt 121 has not passed the alignment mechanism 130, the stop bars 133 on both sides are in a lowered state. Due to placement reasons or the uneven size of the large and small ends of the bamboo fiber reconstituted unit 200 itself, both ends of the bamboo fiber reconstituted unit 200 will not be detected by the first position sensor 131 simultaneously. When the large and small ends of the bamboo fiber reconstituted unit 200 pass by in sequence, the first position sensors 131 of the two alignment mechanisms 130 generate two sequential signal changes. Due to the uneven size of the large and small ends, the time difference of the signal change can be used to identify the orientation of the bamboo fiber reconstituted unit 200.

[0092] Figure 8 This is a side view of the bamboo fiber recombination unit with the stop bar in the extended state. Figure 9 This is a side view of the bamboo fiber reconstituted unit sheet assembly device with the stop bar in the retracted state. Initially, the tops of the stop bars 133 of the two side alignment mechanisms 130 are lower than the upper plane of the first conveyor belt 121. When the first position sensor 131 of one side alignment mechanism 130 detects a signal change, one end of the bamboo fiber reconstituted unit 200 arrives. The control system receives the signal from the first position sensor 131 and controls the first linear drive 132 to move, causing the stop bar 133 to rise, preventing one end of the bamboo fiber reconstituted unit 200 from continuing to advance on the first conveyor belt 121. After a period of time, the first position sensor 131 of the other side alignment mechanism 130 detects a signal change. The control system receives the signal from the first position sensor 131 and controls the first linear drive 132 to move, causing the stop bar 133 to rise. When the first position sensors 131 of both alignment mechanisms 130 detect a signal change, the stop levers 133 of both alignment mechanisms 130 extend to align and straighten the bamboo fiber reconstituted unit 200. After a preset time (e.g., 3 seconds), the control system simultaneously controls the first linear drive components 132 of both alignment mechanisms 130 to move and drive the stop levers 133 back to their initial positions, releasing the obstruction effect on the bamboo fiber reconstituted unit 200. At this time, the bamboo fiber reconstituted unit 200 on the first conveyor belt 121 is aligned, providing conditions for the subsequent pushing and overlapping process. If the first position sensor 131 of one of the two alignment mechanisms 130 detects a signal change, while the first position sensor 131 of the other alignment mechanism 130 does not detect a signal change for an extended period, or if the first position sensors 131 of both alignment mechanisms 130 do not detect a signal change for an extended period, a malfunction occurs and maintenance is required.

[0093] The design of the alignment mechanism 130 in this embodiment of the invention fully considers the structural characteristics of the bamboo fiber recombination unit 200. Through ingenious mechanical design and control strategy (the control strategy includes sequential detection and delay control), a high-quality alignment effect is achieved, laying a solid foundation for the subsequent jacking and overlapping process.

[0094] In this embodiment of the invention, there are two pushing mechanisms 140, but the number of pushing mechanisms 140 can be reasonably selected according to actual conditions. The two pushing mechanisms 140 are respectively positioned at both ends of the length of the bamboo fiber recombination unit 200. A schematic diagram of the pushing mechanism 140 is shown below. Figure 6 As shown, the pushing mechanism 140 includes a second linear drive 141 fixedly mounted on the frame 110. A third linear drive 142 is slidably connected to the second linear drive 141. The second linear drive 141 drives the third linear drive 142 to move back and forth. A push rod 143 is connected to the driving end of the third linear drive 142, and the third linear drive 142 drives the push rod 143 to move up and down. A second position sensor 144 is fixedly mounted on the third linear drive 142. Along the conveying direction, the push rod 143 is located in front of the second position sensor 144. The second position sensor 144 is used to detect the rear edge of the bamboo fiber recombination unit 200 on the first conveyor belt 121 and to detect the front edge of the adjacent bamboo fiber recombination unit 200 in position (located below the forward-curved bamboo fiber recombination unit 200). The second linear drive 141, the third linear drive 142, and the second position sensor 144 are communicatively connected to the control system. The second position sensor 144 is a photoelectric sensor or a proximity sensor. The second linear drive 141 is an electric linear actuator, and the third linear drive 142 is a hydraulic cylinder, a pneumatic cylinder, or an electric linear actuator.

[0095] This embodiment of the invention describes the pushing process of the sheet-forming device 100, which includes the following states:

[0096] 1. Preparation stage:

[0097] The diagram for this stage is as follows: Figure 10 As shown. Initially, the top of the push rod 143 of the pushing mechanism 140 is lower than the upper plane of the first conveyor belt 121. While the control system controls the first linear drive 132 of the two straightening mechanisms 130 to move and drive the stop bar 133 to retract, the control system controls the second linear drive 141 to start running, driving the third linear drive 142 to move slowly towards the direction of the plate. When the second position sensor 144 detects the rear edge of the bamboo fiber reconstituted unit 200 on the first conveyor belt 121, the signal changes, and the control system controls the second linear drive 141 to stop running. At this time, the second conveyor belt 122 is in a stopped state.

[0098] 2. Lifting Phase:

[0099] The diagram for this stage is as follows: Figure 11 As shown. While the control system controls the second linear drive 141 to stop running, it controls the third linear drive 142 to drive the top rod 143 to rise. The front edge of the bamboo fiber reconstituted unit 200 is on the second conveyor belt 122. The top rod 143 lifts the rear end part of the bamboo fiber reconstituted unit 200, causing it to tilt upwards away from the surface of the first conveyor belt 121.

[0100] 3. Overlapping stage:

[0101] The diagram for this stage is as follows: Figure 12 As shown. The rear bamboo fiber reconstituted unit 200 continues forward under the conveyor belt 121, overlapping with the raised front bamboo fiber reconstituted unit 200. When the second position sensor 144 detects the front edge of the rear bamboo fiber reconstituted unit 200, due to the conveying inertia, the rear bamboo fiber reconstituted unit 200 continues to advance until its front edge abuts against the outer wall of the top rod 143, and the front end of the adjacent rear bamboo fiber reconstituted unit 200 is located below the front bamboo fiber reconstituted unit 200.

[0102] 4. Reset Phase:

[0103] The diagram for this stage is as follows: Figure 13 As shown. The second position sensor 144 detects that the adjacent bamboo fiber reconstituted unit 200 has arrived at its position and sends a signal to the control system, which controls the third linear drive 142 to retract the top rod 143. After the overlap is completed, the second conveyor belt 122 resumes its movement, conveying the overlapped multi-layer bamboo fiber reconstituted unit 200 forward, and the weaving mechanism 150 weaves the overlapped bamboo fiber reconstituted unit 200 into a continuous sheet of reconstituted unit.

[0104] Because of the second linear drive member 141, the top rod 143 can move forward before lifting to accommodate the large and small ends of the bamboo fiber reconstituted unit 200. For example, the distance that the second linear drive member 141 at the large end of the bamboo fiber reconstituted unit 200 moves towards the board is greater than the distance that the second linear drive member 141 at the small end of the bamboo fiber reconstituted unit 200 moves towards the board, further ensuring the uniformity of the overlap length at both ends of the bamboo fiber reconstituted unit 200.

[0105] like Figure 6As shown, the bottom end of the push rod 143 is connected to the drive end of the third linear drive 142 via a mounting base 145. The mounting base 145 has an elongated hole 146, the length of which follows the forward direction of the bamboo fiber recombination unit 200. The bottom end of the push rod 143 is threaded, passing through the elongated hole 146, and is fixed to the mounting base 145 using a nut 147. By providing the elongated hole 146 on the mounting base 145, the push rod 143 can be adjusted in its forward and backward mounting position on the mounting base 145, thereby controlling the overlap distance between adjacent bamboo fiber recombination units 200. Specifically, the closer the push rod 143 on the mounting base 145 is to the second position sensor 144, the smaller the overlap distance; the farther the push rod 143 on the mounting base 145 is from the second position sensor 144, the larger the overlap distance. The pushing height can be adjusted by adjusting the screwing position of the nut 147 and the push rod 143. Mounting base 145 has a C-shaped structure. The top plate of mounting base 145 is the part for mounting push rod 143, and the bottom plate of mounting base 145 is the part connected to the drive end of the third linear drive member 142. Push rod 143 passes through the top plate of mounting base 145 through elongated hole 146, and nuts 147 are provided at both the top and bottom of the top plate to fix push rod 143 to the top plate.

[0106] The integrated processing unit features clearly defined process steps and precise mechanical timing coordination, achieving fully automated control. This ensures the continuity of the bamboo fiber recombination unit overlapping process and guarantees product quality. The entire overlapping process eliminates manual operations, significantly reducing the number of operators required, lowering labor costs for enterprises, and improving the working environment and employee safety and health conditions.

[0107] Optionally, a pressing belt assembly 160 is fixedly installed above the front side of the frame 110 to press the overlapped bamboo fiber reconstituted units 200 onto the second conveyor belt 122. The pressing belt assembly 160 includes a third rotation source 161 and multiple third conveyor belts 162 arranged in parallel and spaced apart on the frame 110. The third rotation source 161 is communicatively connected to the control system. The third conveyor belts 162 are located at the front end of the first conveyor belt 121 and above the second conveyor belt 122; the third rotation source 161 drives the third conveyor belts 162 to move synchronously with the second conveyor belt 122. A moving space for the bamboo fiber reconstituted units 200 is formed between the third conveyor belts 162 and the second conveyor belt 122; the bamboo fiber reconstituted units 200 move against the third conveyor belts 162 and the second conveyor belt 122. The overlapped bamboo fiber reconstituted units 200 are always pressed onto the second conveyor belt 122 by the pressing belt assembly 160 before and after the weaving process. The third rotation source 161 can be a device capable of outputting rotation, such as a motor, engine, hydraulic motor, or a combination of one of these with a reducer. Preferably, the third rotation source 161 is a combination of a motor and a reducer.

[0108] The bamboo fiber reconstituted unit 200 is fed into the material receiving position from the first conveyor belt 121. At this time, the ends of the boards may be uneven. To solve the problem of uneven board ends, a pusher mechanism 170 is provided at the rear end of the frame 110 corresponding to the material receiving position of the bamboo fiber reconstituted unit 200. A side baffle 180 is provided on one side of the frame 110 opposite to the pusher mechanism 170. Figure 1 and Figure 3 As shown, the pusher mechanism 170 and the side baffle 180 work together to align the two ends of the bamboo fiber reconstituted unit 200 along its length on the feeding conveyor assembly 120. The pusher mechanism 170 includes a cylinder drive 171, a pusher plate 172, and a third position sensor 173. The cylinder drive 171 is fixed to the rear end of the frame 110 by a bracket, the pusher plate 172 is fixedly connected to the drive end of the cylinder drive 171, and the third position sensor 173 is fixed to the rear end of the frame 110 by a bracket. The cylinder drive 171 and the third position sensor 173 are respectively communicatively connected to the control system.

[0109] When the third position sensor 173 detects the bamboo fiber reconstituted unit 200, the control system commands the cylinder drive 171 to operate, driving the push plate 172 forward. The push plate 172 pushes the bamboo fiber reconstituted unit 200 to the other end of the bamboo fiber reconstituted unit 200 to abut the inner side of the side baffle 180.

[0110] Example 2:

[0111] Example 2 provides a bamboo fiber reconstituted unit processing production line. For example... Figure 14 As shown, the bamboo fiber recombination unit processing production line includes a feeding conveyor 300, a receiving device 400, and a bamboo fiber recombination unit sheet forming device 100 of Example 1.

[0112] The feeding conveying device 300 is located upstream of the bamboo fiber recombining unit sheet forming device 100. The feeding conveying device 300 is used to convey the bamboo fiber recombining unit 200 to the bamboo fiber recombining unit sheet forming device 100.

[0113] The material collection device 400 is located downstream of the bamboo fiber recombination unit integralization device 100 and is used to collect the woven integralization recombination unit.

[0114] like Figure 15As shown, the feeding conveying device 300 includes a main feeding conveyor 310, a first feeding conveyor 320, and a second feeding conveyor 330. The discharge end of the main feeding conveyor 310 is connected to the feed end of the first conveyor belt 121 of the bamboo fiber reconstituted unit sheet forming device 100. The first feeding conveyor 320 and the second feeding conveyor 330 are arranged side by side, and their discharge ends both face the main feeding conveyor 310. The first feeding conveyor 320 and the second feeding conveyor 330 alternately feed the bamboo fiber reconstituted unit 200 to the main feeding conveyor 310.

[0115] Because bamboo naturally grows with thick roots and thinner tips, the resulting bamboo fiber reconstituted units exhibit a significant width gradient along their length. To address the issue of excessive gaps between adjacent units caused by width differences, the feeding conveyor 300 is designed with two parallel feeding conveyors: a first feeding conveyor 320 and a second feeding conveyor 330. These feed bamboo fiber reconstituted units with their wider ends facing forward and those with their narrower ends facing forward, respectively, alternating their feeding to the main feeding conveyor 310. This results in the bamboo fiber reconstituted units exhibiting an alternating "large-small-large-small" arrangement on the first conveyor belt 121 of the sheet-forming device 100, further resolving the problem of large gaps between adjacent bamboo fiber reconstituted units.

[0116] The main feed conveyor 310, the first feed conveyor 320 and the second feed conveyor 330 are all rotary motor driven conveyor belt structures, and the three sets of conveyors are independently controlled by the controller.

[0117] like Figure 14 and Figure 16 As shown, the receiving device 400 includes a first discharge conveyor 410 and a winding assembly 420.

[0118] The first discharge conveyor 410 is located in front of the second conveyor belt 122, and its height is lower than that of the second conveyor belt 122. It is used to convey the coiled reassembly unit after being wound by the winding assembly 420 forward. The first discharge conveyor 410 is a rotary motor driven conveyor belt structure, and the rotary motor is controlled by a controller to run or stop.

[0119] like Figure 16 As shown, there are two sets of winding assemblies 420, located on both sides of the front end of the second conveyor belt 122 and above the first discharge conveyor 410. Each winding assembly 420 includes a slide 421, on which a rotary drive motor 422 is slidably mounted. A reel 423 is mounted at the output end of the rotary drive motor 422. The reels 423 of the two winding assemblies 420 are arranged opposite each other.

[0120] The spool 423 is in the shape of a two-pronged fork. The front end of the continuous sheet-recombining unit is fixed on the spool 423, and the spool 423 rotates under the action of the rotary drive motor 422 to realize the winding of the sheet-recombining unit. After winding, the slide block 421 slides the spool 423 to both sides, and the spool 423 disengages from the sheet-recombining unit roll. The sheet-recombining unit roll falls onto the first discharge conveyor 410. The first discharge conveyor 410 runs, transporting the sheet-recombining unit roll to the other end of the first discharge conveyor 410 for handling or hoisting.

[0121] Example 3:

[0122] Example 3 provides a bamboo processing production line. For example... Figure 17 As shown, the bamboo processing production line includes a feeding conveyor 300, a receiving device 400, and a bamboo fiber recombination unit forming device 100 of Example 1. The feeding conveyor 300 is the same as that of Example 2, except that the receiving device 400 of Example 3 is used to form a folded recombination unit.

[0123] To achieve folded, integrally recombined units, such as Figure 18 As shown, the receiving device 400 includes a second discharge conveyor 430, a folding drive assembly 440, and a receiving tray 450. The receiving tray 450 is used to collect the continuous, sheet-based reassembly units that fall from the sliding roller 443.

[0124] The rear end of the second discharge conveyor 430 is connected to the front end of the second conveyor belt 122, and the front end of the second discharge conveyor 430 is connected to the folding drive assembly 440. The second discharge conveyor 430 is used to supply material to the folding drive assembly 440.

[0125] The folding drive assembly 440 includes a receiving truss 441. An inlet roller 442 is fixedly mounted on one side of the top of the receiving truss 441. The front end of the second discharge conveyor 430 is connected to the inlet roller 442. A sliding roller 443 is slidably mounted on the top of the receiving truss 441, parallel to the inlet roller 442. A drive component is mounted on the receiving truss 441 to drive the sliding roller 443 to slide back and forth. The inlet roller 442 guides the continuous bamboo bundle brought by the second discharge conveyor 430 above the sliding roller 443. As the movable sliding roller 443 rotates, it moves back and forth at a set frequency on the top of the receiving truss 441, causing the continuous bamboo bundle to hang down naturally and fold onto the pre-placed receiving tray 450 below.

[0126] The driving component that drives the sliding roller 443 to slide back and forth is an electric push rod, a synchronous belt driven by a motor, or a gear and rack structure driven by a motor, as long as it can achieve the periodic back and forth movement of the sliding roller 443.

[0127] No manual operation is required during the material cutting and folding process, which greatly reduces the labor intensity of workers, reduces the use of labor costs, and improves the folding efficiency of the whole sheet recombination unit.
