[0017] In one embodiment, a method for processing a thick solid oriented strand board door panel is also included, and the specific implementation method is as follows:

[0018] S1. Put the long core press into the rectangular feed box and the short core press into the fine material feed box;

[0019] S2. The pressure plate is separated from the door frame to obtain a semi-enclosed door frame frame wrapped by the door frame frame and the support base;

[0020] S3. Start the first motor to drive the long core press material from the semi-arc hopper to fall into the support base surface, move the long material laying mechanism, the short core press material falls into the long core press material one-half to three-quarters interval;

[0021] S4 repeats step S3, while the long core pressing material front cover short core pressing material, showing scales superimposed until the bottom surface of the support plate is covered to form a laying;

[0022] S5. Start the short material laying mechanism to evenly cover the bottom surface of the laying part to form the middle core layer;

[0023] S6 repeat steps S3-S4, evenly covering the middle core layer to form a surface laying;

[0024] S7. Close the pressing plate, squeeze the gap between the pressing plate and the supporting bottom plate, and complete the door panel processing.

[0025] The beneficial effects of the present invention are as follows: the present invention is an effective solution to the problem of short pressing and forming, and is a processing device and method for a one-piece thick solid core oriented strand board door panel with strong rigidity. The specific implementation method is as follows:

[0026] The operator will separate the core materials made of eucalyptus that have been sprayed with glue and dehumidified and do not meet the original processing method into long core pressed materials and short core pressed materials. The operator will then put the long core materials into the rectangular feeding box and the short core materials into the fine material feeding box before starting to lay them.

[0027] Since the oriented strand board is laid using the characteristics of plant fibers, the required long core materials and short core materials need to be laid in an intersecting direction: start the first motor to drive the main material-diverting rod to rotate clockwise, and the material-diverting block on the main material-diverting rod will lift the push plate and scrape the long core material upward. At the same time, due to the gap between the push plate and the semi-arc hopper, part of the long core material is drawn out in a straight line along the guiding effect of the guide protrusion and the extrusion effect of the main material-diverting rod, forming the longitudinal laying of the long core material; for the transverse laying of the short core material, the specific implementation method is as follows: The formula is: start the third motor, the third motor drives the linkage belt to rotate in the circumferential direction, and drives the rotating wheel to rotate at the same time. Since the rotating wheel is an eccentric wheel, the rotating wheel pulls the bevel opening block to leave the fit with the bevel limiting block in a staggered manner, and the discharge chute is connected to the short core material. At the same time, due to the meshing action of the side threaded rectangular rod and some threaded through holes, in the process of the bevel opening block leaving the bevel limiting block, the bevel opening block moves upward at the same time, clamping and kneading the short core material through the discharge chute, thereby realizing the horizontal laying of the short core material.

[0028] Since the pressing materials made of hard wood such as eucalyptus are relatively short, their arrangement needs to be changed. After the long-core pressing material falls from the semi-arc hopper onto the surface of the supporting base plate, the second motor is started to drive the movable threaded rod to rotate, and the rectangular feeding box is driven to move laterally until the fine material feeding box falls on top of the long-core pressing material that has been fed. The short-core pressing material is then dropped into the range of one-half to three-quarters of the long-core pressing material. In the process of alternating long-core and short-core material feeding, the front of the long-core pressing material covers the short-core pressing material, showing scales superimposed on each other, until the surface of the supporting base plate is covered to form a bottom surface laying. In this way, during the twisting process of the plate, it is subjected to the interweaving of a large amount of short-core lateral tension and long-core bus tension, and has good toughness and rigidity, similar to the scale structure of a pangolin, which protects the internal product.

[0029] After the bottom surface is laid in the above manner, the middle part can continue to use traditional short core filling, and the upper part continues to lay the scale structure to form a sandwich effect.

[0030] After the semi-enclosed door frame frame wrapped by the door frame and the supporting bottom plate is laid through the above process, the power-assisted motor is started. The power-assisted motor drives the flip frame to move evenly inward, and at the same time drives the cross movable block on the connecting barrel from the rotating groove to the linear groove for flipping. After the two sets of pressing plates are spliced ​​and pressed onto the pressing material, they continue to move inward, squeezing the wedge block through the movable groove, thereby achieving the effect of preliminary compaction of the pressing material by the pressing plate, which is convenient for subsequent operations. After multiple compactions, the reverse rotation power-assisted motor expands the flip frame outward, driving the cross movable block to move from the linear groove to the rotating groove for flipping, and flipping at the same time. The rotating frame also drives the pressure plate to separate from the door frame until the root of the flip frame squeezes and touches the rod, and then aligns the leaking rod notch on the fixing pin with the middle of the lifting nail, causing the lifting nail to fall. After that, the supporting base plate is pulled out of the movable rod through the movable opening slot, and it can be transported to other process construction processing. After a new supporting base plate is refilled into the movable opening slot, the supporting base plate is pushed to move and drive the middle of the lifting nail to continue to fit the leaking rod notch. Then, the flip frame is continued to be rotated to separate from the squeezing and touching rod. The fixing pin is fixed to the limit notch by the push of the recovery spring, completing the fixing of the supporting base plate, and the next work can be carried out.

[0031] The equipment has a simple structure and utilizes a unique laying method and the guiding effect of the guide protrusions to combine the horizontal laying method of the short material laying mechanism to effectively solve the production of oriented strand board with short core material. At the same time, it adopts a scale-like superposition method to obtain strong rigidity, good practicality and economy, which is beneficial to the use of the equipment.

[0059] Advantageously, a method for processing a thick solid core oriented strand board door panel is also included, and the specific implementation method is as follows:

[0060] S1. The long core press is fed into the rectangular feed box 11, and the short core press is fed into the fine material feed box 21;

[0061] S2. The pressure plate 41 is separated from the door frame 42 to obtain a semi-enclosed door frame 42 wrapped by the door frame frame 42 and the support base plate 48;

[0062] S3. Start the first motor 13 to drive the long core press material from the semi-arc hopper 12 to fall into the support base 48 surface, move the long material laying mechanism 1, the short core press material falls into the long core press material one-half to three-quarters interval;

[0063] S4 repeats step S3, while the front of the long core pressing material covered with short core pressing material, showing scales superimposed until the bottom surface of the support plate 48 is covered to form a laying;

[0064] S5 start short material laying mechanism 2, evenly covering the bottom surface of the laying portion to form a central core layer;

[0065] S6 repeat steps S3-S4, evenly covering the middle core layer to form a surface laying;

[0066] S7. Cover the pressing plate 41 and squeeze the gap between the pressing plate 41 and the supporting bottom plate 48 to complete the door panel processing.

[0067] Working principle of the present invention:

[0068] The operator will separate the core material made of eucalyptus that has been sprayed with glue and dehumidified and does not meet the original processing method into long core pressing material and short core pressing material, put the long core material into the rectangular feeding box 11, and put the short core material into the fine material feeding box 21, and then start laying;

[0069] Since the oriented strand board is laid using the characteristics of plant fibers, the required long core material and short core material laying directions need to be crossed: start the first motor 13 to drive the main material-diverting rod 14 to rotate clockwise, and the material-diverting block 141 on the main material-diverting rod 14 lifts the pushing plate 151 to scrape the long core material upward. At the same time, due to the gap between the pushing plate 151 and the semi-arc-shaped feeding hopper 12, part of the long core material is drawn out in a straight line along the guiding effect of the guide protrusion 121 and the extrusion effect of the main material-diverting rod 14, forming the longitudinal laying of the long core material; for the transverse laying of the short core material, the specific implementation method is: start the third Motor 281, the third motor 281 drives the linkage belt 28 to rotate along the circumferential direction, and at the same time drives the rotating wheel 27 to rotate. Since the rotating wheel 27 is an eccentric wheel, the rotating wheel 27 pulls the bevel opening block 25 to leave the fit with the bevel limiting block 24 in a staggered manner, and the discharge trough 231 is connected to the short core material. At the same time, due to the meshing action of the side threaded rectangular rod 273 and the partial threaded through hole 261, in the process of the bevel opening block 25 leaving the bevel limiting block 24, the bevel opening block 25 moves upward at the same time, clamping and kneading the short core material through the discharge trough 231, thereby realizing the horizontal laying of the short core material.

[0070] Since the pressing materials made of hard wood such as eucalyptus are relatively short, their arrangement needs to be changed. After the long-core pressing material falls from the semi-arc hopper 12 onto the surface of the supporting base plate 48, the second motor 34 is started to drive the movable threaded rod 32 to rotate, driving the rectangular feeding box 11 to move laterally until the fine material feeding box 21 falls on top of the long-core pressing material that has been fed. The short-core pressing material is then dropped into the range of one-half to three-quarters of the long-core pressing material. In the process of alternating long-core and short-core material feeding, the front part of the long-core pressing material covers the short-core pressing material, showing scales superimposed on each other, until the surface of the supporting base plate 48 is covered to form a bottom surface laying. In this way, during the twisting process of the plate, it is subjected to the interweaving of a large amount of short-core lateral tension and long-core bus tension, and has good toughness and rigidity, similar to the scale structure of a pangolin, which protects the internal product.

[0071] After the bottom surface is laid in the above manner, the middle part can continue to use traditional short core filling, and the upper part continues to lay the scale structure to form a sandwich effect.

[0072] After the semi-enclosed door frame 42 wrapped by the door frame frame 42 and the supporting bottom plate 48 is laid through the above process, the power-assisting motor 441 is started. The power-assisting motor 441 drives the flip frame 43 to move evenly inward, and at the same time drives the cross movable block 52 on the connecting barrel 51 to pass through the rotating groove 542 to reach the straight groove 541 for flipping. After the two sets of pressing plates 41 are spliced ​​and pressed onto the pressing material, they continue to move inward, squeezing the wedge block 413 through the movable groove 431, thereby achieving the effect of preliminary compaction of the pressing material by the pressing plate 41 for subsequent operation. After multiple compactions, the power-assisting motor 441 is rotated in the opposite direction to expand the flip frame 43 outward, driving the cross movable block 52 to move from the straight groove 541 to the rotating groove 542 for flipping, and at the same time the flip frame 43 is also Drive the pressure plate 41 to separate from the door frame frame 42 until the root of the flip frame 43 squeezes and touches the rod 494, and then aligns the leaking rod notch 492 on the fixing pin 49 with the middle of the lifting nail 47, so that the lifting nail 47 falls. Then, the supporting base plate 48 is pulled out of the movable rod 46 through the movable opening slot 461, and it can be transported to other process construction processing. After a new supporting base plate 48 is refilled into the movable opening slot 461, the supporting base plate 48 is pushed to move and drive the middle of the lifting nail 47 to continue to fit into the leaking rod notch 492. Then, the flip frame 43 is continued to be rotated to separate from the squeezing and touching rod 494. The fixing pin 49 is fixed to the limiting notch 471 by the push of the restoring spring 493, completing the fixing of the supporting base plate 48, and the next work can be carried out.
