[0020] A process for processing cellulose acetate sheet, such as Figure 1-Figure 4 As shown, the process includes the following steps: S1. material preparation, purchasing acetate fiber board to prepare raw materials according to demand; S2. drying, drying the raw materials in S1; S3. mixing, putting the dried raw materials into a reactor to mix and obtain a mixed material; S4. extrusion, connecting the mold assembly to the discharge end of the extruder, and then putting the mixed material into the extruder, and injecting the mixed material into the mold assembly after extrusion; S5. unloading, using the conveying assembly to convey the mold assembly filled with the mixed material to the unloading place and cool and dismantle it to obtain the plate; S6. storage, storing the plate that has been inspected and meets the standards; Furthermore, the mold assembly includes an upper mold 1 and a lower mold 2. A groove 3 and a plurality of slots 4 for accommodating the mixture are provided at the bottom of the upper mold 1. A feeding channel 5 communicating with the groove 3 is provided at the top of the upper mold 1. The plurality of slots 4 are evenly arranged at the edges of the groove 3. A plurality of blocks 6 for inserting into the slots 4 are fixedly connected to the top of the lower mold 2. The blocks 6 are made of a thermal expansion and contraction material and a gap is formed between the blocks 6 and the slots 4 when the blocks 6 are at room temperature. A plurality of heat conduction cavities 7 are provided inside the upper mold 1. The plurality of heat conduction cavities 7 are evenly distributed between the slots 4 and the groove 3 and a brass rod 8 is fixedly connected to the heat conduction cavity 7. After the slots 4 at the bottom of the upper mold 1 are aligned with the blocks 6 at the top of the lower mold 2, the upper mold 1 is installed on the lower mold 2. Then, the upper mold The feed channel 5 at the top of the tool 1 is connected to the discharge end of the extruder. When the mixed material is injected into the groove 3 through the feed channel 5, due to the high temperature of the mixed material when extruded by the extruder, after entering the groove 3, the block 6 will gradually expand under the influence of the heat conduction cavity 7 and the brass rod 8 inside the heat conduction cavity 7, thereby clamping the block 6 and the groove 4 together. After the groove 3 is filled with the mixed material, the mold assembly is separated from the extruder, and then the mold assembly is placed on the conveying assembly, and the conveying assembly is used to convey the mold assembly to the unloading place for unloading. Since the temperature of the mold assembly will gradually decrease during the conveying process, the block 6 will gradually return to its original state and form a gap between the card slot 4, which makes it easier for the operator to separate the upper mold 1 from the lower mold 2, thereby improving the unloading efficiency, thereby improving the overall production efficiency; Furthermore, a plurality of positioning blocks 9 are fixedly connected to the top of the lower mold 2, and the plurality of positioning blocks 9 are located on a side away from the clamping block 6. A plurality of positioning grooves 10 are provided at the bottom of the upper mold 1. The positioning blocks 9 and the positioning grooves 10 cooperate with each other to further improve the firmness of the upper mold 1 and the lower mold 2 when they are connected. Furthermore, the positioning groove 10 passes through the top of the upper mold 1 to the outside and a warning rod 11 is slidably connected in the positioning groove 10. When the positioning block 9 is inserted into the positioning groove 10, the warning rod 11 protrudes from the notch of the positioning groove 10. The staff can judge whether the positioning block 9 is inserted into the positioning groove 10 by observing whether the warning rod 11 protrudes from the notch of the positioning groove 10, thereby ensuring the firmness of the connection between the upper mold 1 and the lower mold 2, and avoiding the occurrence of a gap at the connection when the two are connected; Furthermore, a limiting groove 12 is provided on the inner wall of the positioning groove 10, and a limiting block 13 is fixedly connected to the side wall of the warning rod 11 and is slidably connected to the limiting groove 12. The limiting block 13 cooperates with the limiting groove 12 to limit the warning rod 11 and prevent the warning rod 11 from being separated from the positioning groove 10. Furthermore, the conveying assembly includes a frame 14, a plurality of conveying rollers 15 arranged on the frame 14, a motor 16 connected to any one of the conveying rollers 15, and a control panel for controlling the operation of the motor 16. The plurality of conveying rollers 15 are connected by a conveyor belt 18. A cooling mechanism for cooling the mold assembly is arranged on the frame 14. The control panel is used to drive the motor 16 to drive the conveying rollers 15 to rotate, so as to convey the mold assembly. During the conveying process, the cooling mechanism is used to cool the mold assembly to accelerate the cooling rate, thereby accelerating the recovery of the block 6, and further facilitating the separation of the upper mold 1 and the lower mold 2. Furthermore, the cooling mechanism includes a plurality of cooling boxes 19 arranged on the frame 14, and a cooling chamber 20 is provided in the cooling box 19. The temperature in the plurality of cooling chambers 20 decreases in sequence along the conveying direction of the conveying roller 15. The cooling chamber 20 is connected to an external refrigeration system through a connecting pipe 21. The external refrigeration system is used to convey cold air to the cooling chamber 20 through the connecting pipe 21, and the temperature in the cooling chamber 20 is controlled to gradually decrease along the conveying direction of the conveying roller 15, so as to avoid a sudden drop in temperature affecting the performance of subsequent plates. Furthermore, a cylinder 22 connected to the control panel is provided on one end of the frame 14 near the unloading position, a connecting plate 23 is fixedly connected to the output end of the cylinder 22, a magnet 24 is fixedly connected to the bottom of the connecting plate 23, and an iron sheet 25 is fixedly connected to the top of the upper mold 1. The control panel is used to drive the cylinder 22 to drive the connecting plate 23 to move downward, and the magnet 24 at the bottom of the connecting plate 23 is used to absorb the iron sheet 25 on the top of the upper mold 1, so that the upper mold 1 is separated from the lower mold 2, thereby improving the efficiency of dismantling the mold assembly; Furthermore, a plurality of elastic blocks 17 are fixedly connected to the bottom of the connecting plate 23, and the thickness of the elastic blocks 17 is greater than the thickness of the magnets 24. When the connecting plate 23 moves downward, since the thickness of the elastic blocks 17 is greater than the thickness of the magnets 24, the elastic blocks 17 will fit with the top of the upper mold 1. At this time, there is a certain gap between the magnets 24 and the iron sheets 25 to avoid direct collision between the magnets 24 and the iron sheets 25 and thus affecting the service life of the magnets 24. After the connecting plate 23 continues to move downward, the elastic blocks 17 deform and shrink until the magnets 24 and the iron sheets 25 are attracted to each other.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
