Description

Technical Field

[0001] The present invention relates to a processing technology of recombined bamboo products, and particularly to a whole-piece paving device and a process method for bamboo recombined units. Background Art

[0002] Bamboo recombined units, namely fiberized bamboo veneers, are narrow in width (2 - 12 cm wide). During the process of assembling and paving the recombined units after sizing and drying, manual labor is mainly relied on. The labor intensity is high, the efficiency is low, and it is difficult to pave evenly. As a result, the density and performance of different parts of the prepared recombined bamboo vary greatly, and phenomena such as wire skipping, cracking, and deformation are likely to occur, and the performance of the recombined bamboo is unstable. Therefore, there is an urgent need to design a mechanical device to replace the manual assembling and paving method, so as to improve the preparation efficiency of recombined bamboo and realize the continuity of the preparation process. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a whole-piece paving device for bamboo recombined units in view of the deficiencies of the above-mentioned prior art.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is: A whole-piece paving device for bamboo recombined units, characterized in that it includes a conveyor belt, a quilting head, a winding device, and a cutting device. A plurality of the conveyor belts are connected in parallel through a frame to form a conveying bottom frame, the conveying bottom frame is installed on a machine frame, the conveying inlet of the conveyor belt is communicated with the conveyor belt outlet of the previous process, the bamboo recombined units are conveyed on the conveying bottom frame, a plurality of quilting heads for stitching and connecting the bamboo recombined units to form a bamboo curtain are equidistantly installed above the conveying bottom frame, a winding device for winding the bamboo curtain is arranged in front of the conveying outlet of the conveying bottom frame, and a cutting device for cutting the bamboo curtain is arranged below the conveying outlet of the conveying bottom frame.

[0005] Preferably, the winding device includes a rotating arm and a winding disc. The middle position of the rotating arm is fixedly connected to the output shaft of a commutation motor, the commutation motor is fixedly connected to the machine frame through a motor bracket, the two ends of the rotating arm are rotationally connected to two winding discs through bearings, a winding motor for driving the winding disc to rotate is arranged at the end of the rotating arm, and two winding rods are symmetrically arranged on both sides of the center position of the winding disc. The gap between the two winding rods passes through the end of the bamboo curtain. When one winding disc is full of the bamboo curtain, the commutation motor rotates to make the two winding discs change positions and continue to wind the bamboo curtain.

[0006] Preferably, the cutting device includes a cutting track, a cutting motor, and a cutting saw blade. The cutting track is fixedly installed on the frame. The cutting track is located below the conveying outlet end of the conveying chassis. The cutting motor is movably installed on the cutting track. The rotating shaft of the cutting motor is coaxially and fixedly connected to the cutting saw blade. The top of the cutting saw blade is higher than the top surface of the bamboo curtain. The bamboo curtain is cut off by the cutting saw blade after the receiving tray is full. The bottom of the cutting motor is fixedly connected to a slider, and the slider is slidably connected to the cutting track. The cutting motor can be manually pushed, or a motor bridge can be installed on the cutting track, and the motor bridge is then connected to the slider. The motor bridge is a structure for connecting the motor and the slide rail system, and is used to realize the reciprocating movement of the slider in the slide rail driven by the motor.

[0007] Preferably, a gantry is provided above the conveying chassis. The gantry is fixed on the frame. The gantry is perpendicular to the conveying chassis. A plurality of quilting heads are equidistantly installed on the gantry. The stitching action of the quilting heads is directly opposite to the bamboo reconstituted unit.

[0008] Preferably, a front limiting roller shaft and a rear limiting roller shaft are provided on the front and rear sides of the gantry. Both ends of the front limiting roller shaft and the rear limiting roller shaft are rotatably installed on the frame. The front limiting roller shaft is connected to a motor. The rear limiting roller shaft is a power-free roller shaft. A plurality of thickness-limiting guide wheels are equidistantly arranged on the front limiting roller shaft. A plurality of guiding wheels are equidistantly arranged on the rear limiting roller shaft. The vertical distance between the thickness-limiting guide wheels, the guiding wheels and the conveyor belt is greater than the thickness of a single-layer bamboo reconstituted unit and less than the thickness of a double-layer bamboo reconstituted unit. The thickness-limiting guide wheels can assist in correcting the bamboo reconstituted units with overlapping inclined lap sizes exceeding the requirements, ensuring uniform overlap between adjacent bamboo reconstituted units and facilitating stitching. The guiding wheels play a guiding role for the bamboo curtain, facilitating accurate winding of the bamboo curtain, and ensuring that the bamboo curtain is not broken or offset after cutting.

[0009] Preferably, a speed difference is set between the conveyor belt and the conveying device of the previous process, ensuring that the bamboo reconstituted units are orderly overlapped along the long sides before quilting on the conveyor belt, and the density is adjustable, facilitating quilting.

[0010] A process method for whole-sheet paving of bamboo reconstituted units using the whole-sheet paving equipment for bamboo reconstituted units described above includes the following steps: S1. The bamboo reconstituted units after sizing and drying, namely the bamboo veneers after sizing, are sequentially overlapped along the long sides at the inlet end of the conveyor belt and conveyed forward by the conveyor belt. During the overlapping process of the bamboo veneers after sizing, the density of the bamboo curtain after stitching is controlled by controlling the overlap size. The larger the overlap size, the more bamboo veneers there are in the bamboo curtain per unit area, that is, the greater the density of the bamboo curtain. The bamboo curtain with an overlap size of 2-5 mm is a high-density bamboo curtain, and the bamboo curtain with an overlap size of 0-2 mm is a low-density bamboo curtain; S2. During the forward movement of the bamboo veneer after gluing, it is stitched and connected by a quilting head to form a bamboo curtain. The stitching direction is perpendicular to the long side direction of the bamboo veneer after gluing, and the long side direction of the bamboo veneer after gluing is also the fiber direction of the bamboo. S3. Insert the front end of the bamboo curtain between two winding rods on the same receiving tray. Start the winding motor to drive the receiving tray to rotate and wind the bamboo curtain. S4. When the winding diameter limit of a single receiving tray is reached, start the cutting motor and drive the cutting motor to move along the cutting track to cut and disconnect the bamboo curtain. S5. Start the transposition motor to rotate the rotating arm by 180° to swap the positions of the two receiving trays. Repeat S3 - S4 until the other receiving tray reaches the winding limit. The wound bamboo curtain is cut by a paving cutting saw according to a preset size and then enters the paving and blanking process. When paving and blanking, the bamboo curtain with high density is paved on the surface part of the paved bamboo curtain blanking group, and the bamboo curtain with low density is paved on the core layer part of the paved bamboo curtain blanking group. The paved bamboo curtain blanking group is prepared into recombinant bamboo by a hot pressing forming process.

[0011] Preferably, when the bamboo recombinant unit in S1 is conveyed, the speed of the conveyor belt is dynamically adjusted by a controller, and the overlapping size is controlled by controlling the speed difference between the conveyor belt and the conveying speed of the drying process.

[0012] Preferably, a gradient density weaving is set when stitching and weaving the bamboo curtain. The quilting head is a quilting head with an adjustable stitch pitch of 0.5 - 3 mm; the stitching density of the bamboo curtain is 1 - 3 stitches / cm.

[0013] Preferably, after the bamboo recombinant unit after sizing undergoes the drying process, thickness sorting is carried out. The bamboo recombinant units with the same thickness are conveyed into the conveyor belt in the same batch. The thickness error range of the thickness sorting is ±3 mm. At the outlet of the drying process, the moisture content of the bamboo recombinant unit is detected by an infrared thermal imager and is not greater than 12%. When the moisture content is greater than 12%, the drying time is extended to continue drying until the moisture content is below 12%. The thickness sorting and moisture content detection are carried out synchronously.

[0014] The present invention has the following advantages compared with the prior art: 1. The present invention conveys the bamboo recombinant unit through a conveyor belt, stitches and forms a bamboo curtain through a quilting head, winds the bamboo curtain through a receiving tray. After a single receiving tray is full, the bamboo curtain is cut off by a cutting saw blade and the two receiving trays are transposed to continue winding the bamboo curtain. The design is scientific and reasonable, and the practicability is strong.

[0015] 2. The present invention drives the rotating arm to rotate 180° by a transposition motor to swap the positions of the receiving trays at both ends, improves the work efficiency, increases the volume of the bamboo curtain wound at one time. The wound bamboo curtain is convenient for flexible cutting of the bamboo curtain width in the subsequent hot pressing process, and can reduce the occupancy rate of the storage space.

[0016] 3. The process of the present invention mainly includes the long-edge lapping and conveying - sewing into a bamboo curtain - winding - cutting - paving of the bamboo-based recombinant units from the drying process, and detecting the moisture content and lapping density of the bamboo-based recombinant units. In addition, in the paving process, bamboo curtains with high density are paved on the surface part of the recombinant bamboo, and bamboo curtains with low density are paved on the core part of the recombinant bamboo. After paving, the bamboo curtains are prepared into recombinant bamboo by hot pressing. The structural design of the present invention is scientific and reasonable, which can efficiently and quickly sew bamboo-based recombinant units to form a bamboo curtain and pave the blank, with high processing efficiency, good flatness of the whole sheet, being beneficial to improving the performance of recombinant bamboo, expanding the application range of recombinant bamboo, having strong practicability and good economic benefits.

At the exit of the drying process, the moisture content of the bamboo reorganization units 4 is detected by an infrared thermal imager to be no more than 12%.
