After the cloth feeding cup 33 is filled with materials, it runs above the mold 41 of the hydraulic press 4 through the two-axis telescopic mechanism 34. The cloth feeding cup 33 is opened, and the urea-formaldehyde powder falls into the mold 41. The cloth feeding cup 33 withdraws from the mold 41, and the mold 41 of the hydraulic press 4 closes to start forming. At the same time, the cloth feeding cup 33 continues to receive materials in a cycle and prepares for the next cycle. After the forming of the hydraulic press 4 is completed, the mold 41 is opened. After receiving the signal that the mold opening is completed, the robot 6 enters the mold 41, takes out the product, and runs to the high-speed spindle 51 of the trimming machine 5 for trimming operation. The flying edges falling off during trimming are broken by the crushing mechanism 52 below and fall into the collection box 53. After trimming, the robot 6 transports the product to the polishing machine 7. The turning fixture 71 on the polishing machine 7 sucks and turns the product over, and then transfers it to the polishing fixture 72 below. The polishing fixture sends the product into the interior of the polishing machine 7, and the cloth wheel 73 polishes the product. After polishing, the polishing fixture 72 sends out the product. The turning fixture 71 sucks up the product from the polishing fixture 72, rises and turns it over, and then the robot 6 takes away the product and places it on the shaping table 8 for shaping. After shaping, the handling fixture 91 on the discharging table takes out the product from the shaping table 8 onto the belt conveyor 10. Finally, the product is conveyed by the belt conveyor 10 to the manual operation area 12 for cleaning and packaging. The manual operation area 12 is equipped with a finished product area 14, a semi-finished product area 15, a packaging material rack 16, a workbench 17, a testing table 18, a sealing machine 19, etc.
