Description

Technical Field

[0001] The invention relates to the technical field of composite board production, in particular to a production process of a bamboo fiber composite board. Background Art

[0002] During the production of bamboo fiber composite materials, bamboo fiber is compounded with other materials such as plastic, rubber, metal, etc. to prepare new materials with high strength, high toughness, damage resistance, corrosion resistance and other properties. They can be used in automotive interiors, aerospace, construction and other fields, such as automotive interior panels, aircraft seat components, building structural parts, etc. The production process mainly includes raw material preparation, fiber mixing, high-temperature pressing, cooling and shaping, splicing and cutting, and surface treatment. When splicing and cutting, a splicing machine is required to splice and cut them to meet the usage requirements.

[0003] The existing bamboo fiber composite board production process is used. When splicing and cutting, it is necessary to first perform a mortise and tenon operation on both ends of the bamboo fiber composite board, then apply glue to the mortise and tenon groove, and then the operators have to splice the boards one by one, which makes the splicing efficiency very low; when splicing and cutting, the two ends of the bamboo fiber composite board are prone to bumping, resulting in uneven ends. At the same time, it is not convenient to perform synchronous mortise and gluing operations on the two ends of the bamboo fiber composite board, and the glue application is not uniform, which affects the efficiency and quality of the splicing; when butt-jointing, it is not convenient to align and press the bamboo fiber composite board, and when cutting, it is not convenient to cut to a fixed length, which affects the quality of the splicing.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) This bamboo fiber composite board production process, by setting a grinding mechanism, etc., when the bamboo fiber composite board is extended, first a plurality of bamboo fiber composite boards are stacked and placed between two first guide plates, then the conveyor is started to drive the conveyor belt for conveying, when the fixed block is against the bamboo fiber composite board in the first guide plate, it can push a bamboo fiber composite board at the bottom to be conveyed along the top of the supporting plate, at the same time, when the conveyed bamboo fiber composite board is against the conical surface, it can push the first conveying roller and the first moving frame to move upward, and at the same time, the third spring is compressed, and, under the action of the third spring, the first conveying roller is against the top of the bamboo fiber composite board, and the conveyor is started. The second motor is started, and the rotation of the second motor drives the rotation of the first conveying roller, thereby pushing the bamboo fiber composite board to collide with the side wall of one of the polishing plates, so that one end of the bamboo fiber composite board can be polished. After the polishing is completed, the second motor is started to reverse, and the bamboo fiber composite board can be pushed to collide with the side wall of the other polishing plate, so as to facilitate the polishing operation of both ends of the bamboo fiber composite board, ensure the quality of subsequent mortising and docking, and thus ensure the production quality. In addition, when polishing, the dust suction fan is started. At this time, the debris generated can be absorbed through the hole, and enter the external filter device through the dust suction hood and the dust suction fan for filtration and collection, which is healthier and more environmentally friendly.

[0027] (2) The production process of the bamboo fiber composite board is to set up a tenoning and gluing mechanism, etc. After the bamboo fiber composite board is polished, when it is transported between the two tenoning rollers, the conveyor is stopped. At this time, the bamboo fiber composite board is stopped from being transported. Then, the third motor is started. The rotation of the third motor drives the rotation of the double-headed screw, thereby driving the two moving blocks to move closer to each other, and drives the tenoning rollers and the inclined plate to move through the U-shaped plate. When the inclined plate and the end of the bamboo fiber composite board are against each other, it can push the bamboo fiber composite board to be adjusted in the center. After the adjustment is completed, when the moving block continues to move, it can push the inclined plate to slide upward along the two ends of the bamboo fiber composite board and drive the moving plate to move upward. The first spring is stretched, and at the same time, the electromagnet is energized. When the magnet is energized, it attracts the iron block, causing the rectangular tube to drive multiple glue-coating tubes to move. At the same time, the sixth spring is compressed and moves the glue-coating tube into the slot. When the bottom of the inclined plate moves to the top of the bamboo fiber composite board, the bamboo fiber composite board can be pressed under the action of the first spring. At the same time, the first distance sensor detects that the distance of the moving plate no longer changes. At this time, the third motor is stopped, and then the first motor is started. The rotation of the first motor drives the rotation of the tenoning roller. Then, the third motor is started again, so that the U-shaped plate drives the tenoning roller to continue moving a certain distance, and the tenoning operation can be performed on both ends of the bamboo fiber composite board. In addition, it can be applied to bamboo fiber composite boards of different lengths, has stronger applicability, and is more convenient and quick to use. At the same time, when the movable plate moves upward, it drives the piston to move upward along the fixed tube, so that negative pressure is generated in the fixed tube. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the glue in the glue box enters the fixed tube through the first hose for temporary storage. After the tenoning is completed, the two U-shaped plates and the tenoning roller are driven away from each other by the second moving mechanism. At this time, the inclined plate slides along the top of the bamboo fiber composite board. When the inclined plate and the two ends of the bamboo fiber composite board are against each other, the inclined plate and the movable plate can move downward and reset under the action of the first spring, so that the inclined plate slides downward along the two ends of the bamboo fiber composite board. At this time, the bristles can clean the debris in the tenon groove. When the glue coating tube is flush with the top of the tenon groove, the electromagnet is turned off. At this time, the rectangular tube can It can be reset by moving away from the U-shaped block under the action of the sixth spring, and drive the glue coating tube to move toward the direction close to the mortise through the second telescopic mechanism. When the glue coating tube is against the surface of the mortise, the second spring is compressed, thereby ensuring that the end of the glue coating tube can contact the surface of the mortise, and when the movable plate moves downward, it can drive the piston to move downward along the fixed tube, thereby squeezing the glue temporarily stored in the fixed tube. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the glue in the fixed tube is squeezed and enters the rectangular tube through the second hose, and is smeared on the surface of the mortise through the glue coating tube and the groove, making gluing more convenient and quick, and making the gluing more uniform and effective, thereby ensuring the quality of subsequent splicing.

[0028] (3) The production process of bamboo fiber composite board is to set up a docking and cutting mechanism, etc. After the mortise and tenoning and gluing are completed, the conveyor is started, so that the conveyor belt and the fixed block drive the bamboo fiber composite board to continue to be transported forward along the top of the load-bearing plate. When it moves to the docking position, the conveyor is stopped, and then the first cylinder is started to make the first push plate abut against one end of the bamboo fiber composite board, and slide along the second guide plate to the center and dock with the bamboo fiber composite board that has been extended in front. At the same time, under the action of the fourth spring, the second conveying roller abuts against the top of the bamboo fiber composite board, which can press the bamboo fiber composite board that has been extended in front, ensure the constant extrusion force during docking, and avoid When the bamboo fiber composite board is connected, the offset and shaking are generated, thereby ensuring the quality of the connection. After the connection is completed, the second conveyor roller can press and convey the bamboo fiber composite board. When the connected bamboo fiber composite board is against the side wall of the baffle, the baffle is pushed to move toward the fixed plate. When the second distance sensor detects that the baffle is a certain distance away from the fixed plate, the first cylinder is stopped. Then, the connected bamboo fiber composite board is cut by the cutting module, and the second cylinder is started. The cut bamboo fiber composite board is pushed into the collection tank for collection through the second push plate to achieve fixed-length cutting, which can ensure the quality of the connection and realize continuous automatic connection operation to improve the efficiency of the connection.

[0063] Working principle: When in use, when extending the bamboo fiber composite board, first stack multiple bamboo fiber composite boards and place them between the two first guide plates 1903. Then, start the conveyor 13 to drive the conveyor belt 1301 for transportation. When the fixed block 14 abuts against the bamboo fiber composite board in the first guide plate 1903, it can push the bottom bamboo fiber composite board to be transported along the top of the supporting plate 18. At the same time, when the transported bamboo fiber composite board abuts against the conical surface 307, it can push the first conveying roller 303 and the first moving frame 301 to move upward. At the same time, the third spring 306 is compressed, and when the third spring 306 is pressed against the first guide plate 1903, the first conveying roller 303 and the first moving frame 301 are pressed against the first guide plate 1903. Under the action of 306, the first conveying roller 303 is abutted against the top of the bamboo fiber composite board, and the second motor 302 is started. The rotation of the second motor 302 drives the rotation of the first conveying roller 303, thereby pushing the bamboo fiber composite board to abut against the side wall of one of the polishing plates 1901, so that one end of the bamboo fiber composite board is polished. After the polishing is completed, the second motor 302 is started to reverse, and the bamboo fiber composite board can be pushed against the side wall of the other polishing plate 1901, thereby facilitating the polishing operation on both ends of the bamboo fiber composite board, ensuring the quality of subsequent mortising and docking, and thus ensuring production quality;

[0064] After the bamboo fiber composite board is polished, when it is transported between the two tenoning rollers 2004, the conveyor 13 is stopped, and the transportation of the bamboo fiber composite board is stopped. Then, the third motor 703 is started, and the rotation of the third motor 703 drives the rotation of the double-headed screw 702, thereby driving the two moving blocks 2002 to move closer to each other, and drives the tenoning rollers 2004 and the inclined plate 2007 to move through the U-shaped plate 2003. When the inclined plate 2007 is against the end of the bamboo fiber composite board, it can push the bamboo fiber composite board to be centered. After the adjustment is completed, when the moving block 2002 continues to move, it can push the inclined plate 2007 along The two ends of the bamboo fiber composite board slide upward, driving the movable plate 2006 to move upward. The first spring 403 is stretched, and at the same time, the electromagnet 606 is energized. After the electromagnet 606 is energized, it attracts the iron block 607, causing the rectangular tube 2011 to drive the multiple glue tubes 2012 to move. At the same time, the sixth spring 605 is compressed, and the glue tubes 2012 are moved into the slot 2010. When the bottom of the inclined plate 2007 moves to the top of the bamboo fiber composite board, the bamboo fiber composite board can be pressed under the action of the first spring 403. At the same time, the first distance sensor 2008 detects that the distance between the movable plate 2006 no longer changes.

[0065] At this time, the third motor 703 is stopped, and then the first motor 2005 is started. The rotation of the first motor 2005 drives the rotation of the tenoning roller 2004. Then, the third motor 703 is started again, so that the U-shaped plate 2003 drives the tenoning roller 2004 to continue to move a certain distance, so that the tenoning operation can be performed on both ends of the bamboo fiber composite board. In addition, it can be applied to bamboo fiber composite boards of different lengths, with stronger applicability, more convenient and quicker use. At the same time, when the movable plate 2006 moves upward, it drives the piston 203 to move upward along the fixed tube 202, so that negative pressure is generated in the fixed tube 202. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the glue in the glue box 201 enters the fixed tube 202 through the first hose 204 for temporary storage.

[0066] After the tenoning is completed, the two U-shaped plates 2003 and the tenoning roller 2004 are driven to move away from each other by the second moving mechanism 7. At this time, the inclined plate 2007 slides along the top of the bamboo fiber composite board. When the inclined plate 2007 is against the two ends of the bamboo fiber composite board, the inclined plate 2007 and the movable plate 2006 can move downward and reset under the action of the first spring 403, so that the inclined plate 2007 slides downward along the two ends of the bamboo fiber composite board. At this time, the bristles 2009 can clean the debris in the tenon groove, and the glue tube 201 is glued. 2 is flush with the top of the mortise, the first distance sensor 2008 detects the distance change of the movable plate 2006 and determines that the electromagnet 606 is powered off. At this time, the rectangular tube 2011 can be moved away from the U-shaped block 601 and reset under the action of the sixth spring 605, and the second telescopic mechanism 5 drives the glue coating tube 2012 to move toward the mortise. When the glue coating tube 2012 contacts the surface of the mortise, the second spring 502 is compressed, thereby ensuring that the end of the glue coating tube 2012 can contact the surface of the mortise.

[0067] Furthermore, when the movable plate 2006 moves downward, it can drive the piston 203 to move downward along the fixed tube 202, thereby squeezing the glue temporarily stored in the fixed tube 202. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the glue in the fixed tube 202 is squeezed and enters the rectangular tube 2011 through the second hose 205, and is smeared on the surface of the tongue and groove through the glue-applying tube 2012 and the groove 2013, making the glue application more convenient and quick, and making the glue application more uniform and effective, thereby ensuring the quality of the subsequent splicing, and being applicable to bamboo fiber composite boards of different thicknesses.

[0068] Moreover, during production, the dust suction fan 17 is started. At this time, the through hole 15 can absorb the generated debris, and then pass through the dust suction cover 16 and the dust suction fan 17 and enter the external filter device for filtration and collection, which is more healthy and environmentally friendly.

[0069] After the tenoning and gluing are completed, the conveyor 13 is started, so that the conveyor belt 1301 and the fixed block 14 drive the bamboo fiber composite board to continue to be conveyed forward along the top of the supporting plate 18. When it moves to the docking position, the conveyor 13 is stopped, and then the first cylinder 2107 is started, so that the first push plate 2108 is abutted against one end of the bamboo fiber composite board, and slides along the second guide plate 2105 to the center and docks with the bamboo fiber composite board after being extended in front. At the same time, under the action of the fourth spring 805, the second conveying roller 802 is abutted against the top of the bamboo fiber composite board, which can press the bamboo fiber composite board after being extended in front, ensure the constant extrusion force during docking, and avoid deviation and shaking during docking, thereby ensuring the quality of docking;

[0070] After the docking is completed, the second conveyor roller 802 can press and convey the bamboo fiber composite board. When the spliced bamboo fiber composite board is against the side wall of the baffle 901, the baffle 901 is pushed to move toward the fixed plate 903. When the second distance sensor 905 detects that the baffle 901 is a certain distance away from the fixed plate 903, the first cylinder 2107 is stopped, and then the spliced bamboo fiber composite board is cut by the cutting module 2104. In addition, the second cylinder 2111 is started, and the cut bamboo fiber composite board is pushed into the collection tank 2113 for collection through the second push plate 2112 to achieve fixed-length cutting, which can ensure the quality of the splicing and realize continuous automatic splicing operation to improve the efficiency of the splicing.
