This structure enables the horizontal bidirectional hydraulic cylinder 13 to push materials toward both sides through the push plates 12 on both sides during the repeated extension and retraction of the hydraulic rod, so that the work done by the hydraulic rod of the horizontal bidirectional hydraulic cylinder 13 during the recovery can be utilized, and the useless work when the cylinder retreats can be fully utilized to improve the utilization rate of the power source. Compared with stamping processing, the same power consumption can produce double the finished products, and the hydraulic push is also It can effectively reduce the noise during production. A material unloading bottom plate 18 is provided on the outside of the bottom end of the push plate 12, and a wood board production machine mainframe 15 is provided on the outside of the bottom end of the material unloading bottom plate 18. An avoidance through hole 14 is provided on the outside of the wood board production machine mainframe 15, and the avoidance through hole 14 is provided with a vertical through hole structure above and a horizontal through hole structure below. This structure enables equipment to be installed on the inner walls on both sides of the horizontal sides of the vertical through hole above the avoidance through hole 14, and the horizontal through hole below the avoidance through hole 14 is convenient for users to clean dust. Both sides of the top of the avoidance through hole 14 are rotatably connected with a feed roller shaft 1, and the top surface height of the feed roller shaft 1 is equal to the top surface height of the wood board production machine mainframe 15. This structure enables the board material that falls to the top surface of the wood board production machine mainframe 15 to be conveniently moved through the feed roller shaft 1, thereby reducing the movement. The friction force generated when the board production machine mainframe 15 is moved is generated when the board production machine mainframe 15 is moved. The bottom of the board production machine mainframe 15 is equipped with a support foot 19, and the top surface height of the board production machine mainframe 15 is lower than the top surface height of the lower mold cavity plate 5. This structure allows the board on the lower mold cavity plate 5 to easily fall onto the top surface of the board production machine mainframe 15, and there will be no situation where the top surface of the board production machine mainframe 15 is too high and the board cannot be lifted and moved. A limit frame 22 is installed on the top of the board production machine mainframe 15, and a feed chute box 10 is installed on the side of the limit frame 22. The feed chute box 10 is a coverless rectangular structure, and both sides of the feed chute box 10 are penetrated and connected with feed bearings 9, and a feed roller shaft 11 is installed on the outer wall of the feed bearing 9, and the feed bearing 9 is located on the end face of the outer side of the feed chute box 10. The feed chute box 1 0 A material discharge slot 21 is provided inside the bottom end, and a compaction bearing 7 is rotatably connected to the outside of the side of the material discharge chute box 10. A compaction roller shaft 8 is installed on the outer wall of the compaction bearing 7, and a chain belt 23 is connected to the outside of the end face of the compaction roller shaft 8. This structure enables the material in the material discharge chute box 10 to be discharged through the rotating compaction roller shaft 8. There is no restriction on the material. The materials that can be used include: wood shavings, straw, rice husks, peanut shells, etc. The compaction roller shaft 8 is located directly above the material discharge bottom plate 18. This structure enables the material in the material discharge chute box 10 to rotate through the material discharge roller shaft 11 and fall onto the material discharge bottom plate 18 and be pushed forward by the compaction roller shaft 8. The compaction roller shaft 8 can rotate differently to compact the material, so that the material has a mobile density and is pushed into the mold cavity, effectively solving the problem of too little plate output each time.The chain belt 23 is externally connected to a servo motor 24, and a material discharge chute box 10 is externally installed at the bottom end of the servo motor 24. Storage slots 16 are provided on both sides of the interior of the lower side of the main body 15 of the wood board production machine, and a hydraulic push rod 17 is installed inside the storage slot 16, and the top of the hydraulic push rod 17 is respectively connected to the lower mold cavity plate 5 and the material discharge bottom plate 18. This structure allows the user to adjust the height of the lower mold cavity plate 5 and the material discharge bottom plate 18 through the hydraulic push rod 17. The top height of the lower mold cavity plate 5 is not higher than the top height of the material discharge bottom plate 18, and the height difference between the bottom surface of the compacting roller shaft 8 and the top surface of the material discharge bottom plate 18 is equal to the thickness of the push plate 12.

The upper mold cavity plate 6 is installed on the top of the wood board production machine mainframe 15 directly above the lower mold cavity plate 5, and the upper mold cavity plate 6 is connected to the heating plate 4. This structure allows the board to be preliminarily heated at a low temperature through the upper mold cavity plate 6 and the lower mold cavity plate 5 in the upper mold cavity plate 6 and the lower mold cavity plate 5, effectively reducing the airflow and avoiding the cracking of the board. The auxiliary heating frame 2 is installed on the top of the outer side of the wood board production machine mainframe 15, and the auxiliary heating frame 2 is connected to the heating pipe 3. This structure allows the board to be heated and cured for a second time through the heating pipe 3 to improve the firmness.

[0017] Working principle: When using the bidirectional extrusion formaldehyde-free fireproof hollow core door core board production equipment, first, the user can place the horizontal bidirectional hydraulic cylinder 13 at a suitable position in the workshop through the support feet 19 at the bottom of the hydraulic cylinder fixing seat 20, and then install the two sides of the horizontal bidirectional hydraulic cylinder 13 with the limit frame 22 and the push plate 12 between the main body 15 of the wooden board production machine, and then the user can pour the wood into the unloading chute box 10 on the top of the main body 15 of the wooden board production machine on both sides of the horizontal bidirectional hydraulic cylinder 13, and then start the hydraulic push rod 17 in the storage slot 16 to raise the lower mold cavity plate 5 and the unloading bottom plate 18 to a suitable height, and then start the servo motor 24 to drive the compaction bearing 7 and the unloading bearing 9 to rotate through the chain belt 23, so that the unloading roller shaft 11 outside the unloading bearing 9 The material will be pushed downward to drop the material through the discharge slot 21 onto the push plate 12. The user can control the material amount by adjusting the rotation speed of the discharge roller shaft 11, and then the push plate 12 will push the material toward the bottom of the compacting roller shaft 8 under the push of the horizontal two-way hydraulic cylinder 13. The material will be initially compacted to a certain density and then pushed onto the lower mold cavity plate 5. The material entering between the lower mold cavity plate 5 and the upper mold cavity plate 6 can be shaped and initially heated by the heating plate 4. Since the temperature at this time is not too high, a large amount of airflow will not be generated during production. After the plate is formed, it is pushed into the auxiliary heating rack 2, and can be heated and cured again through the heating pipe 3. Then, it is transported to the subsequent workstation by rolling the feeding roller shaft 1 in the avoidance through hole 14, thereby completing a series of tasks.
