[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a linear rail structure of a pulp molding machine with an oil sump, including a base 1 of the molding machine. A pulp pool 101 is provided in the middle of the base 1 of the molding machine. Lower die racks 2 are fixedly installed on the upper surfaces on both sides of the base 1 of the molding machine. An upper die optical axis 3 is fixedly installed above the outer side of the base 1 of the molding machine near the lower die rack 2. The hot pressing lower die makes a horizontal reciprocating motion above the lower die rack 2 through the meshing of gears. Lubricating oil needs to be added between the gear and the rack for lubrication. The hot pressing upper die makes a vertical reciprocating motion between the upper die optical axes 3 through the drive of a cylinder or an oil cylinder. Lubricating oil needs to be added between the moving mating surface of the hot pressing upper die and the upper die optical axis 3 for lubrication. A retaining ring 4 is fixedly installed at the lower end of the upper die optical axis 3. The retaining ring 4 is concentric with the upper die optical axis 3. The inner diameter of the retaining ring 4 is larger than the outer diameter of the upper die optical axis 3. The retaining ring 4 is fixed on the upper surface of the base 1 of the molding machine by screws. The retaining ring 4 and the base 1 of the molding machine are sealed by a rubber sealing ring. One end of the oil guiding groove 102 communicates with the pulp pool 101 and the other end communicates with the inside of the retaining ring 4. The lubricating oil flowing down from the upper die optical axis 3 first falls into the retaining ring 4, then into the oil guiding groove 102, and finally flows out from the other end of the oil guiding groove 102. An oil guiding groove 102 is provided below the retaining ring 4 on the base 1 of the molding machine. An oil guiding strip 5 is fixedly installed above the inner side surface of the pulp pool 101. A U-shaped oil sump 6 is installed above the oil guiding strip 5. The oil guiding strip 5 is a V-shaped plate. One side of the oil guiding strip 5 is horizontally fixed below the oil guiding groove 102 by full welding. The other side of the oil guiding strip 5 is tilted outwards. The U-shaped oil sump 6 is fixedly installed below the oil guiding strip 5 by screws at both ends, and the inner side edge of the U-shaped oil sump 6 is inserted into the oil guiding strip 5. The lubricating oil flowing out from the oil guiding groove 102 is guided by the oil guiding strip 5 and falls into the U-shaped oil sump 6. The length dimension of the oil guiding strip 5 is larger than the length dimension of the pulp pool 101, so that all the lubricating oil flowing down from the lower die rack 2 above the pulp pool 101 area is received by the oil guiding strip 5 and guided into the U-shaped oil sump 6. Both ends of the U-shaped oil sump 6 are open and a container for storing lubricating oil is installed below. The oil retaining strip 7 is fixedly installed around the lower die rack 2 by laser full welding. A certain distance is provided between the oil retaining strip 7 and the lower die rack 2, and a groove communicating with the oil guiding groove 102 is formed around the oil retaining strip 7. The lubricating oil overflowing from the oil retaining strip 7 flows into the groove and then flows out from the oil guiding groove 102.

[0025] During use, workers still regularly add lubricating oil to the gear rack and the optical axis at regular intervals. The difference is that when the overflowing lubricating oil flows down to the base 1 of the molding machine, it will be collected uniformly. Specifically, the lubricating oil flowing down from the optical axis is surrounded by the retaining ring 4 after falling onto the base 1 of the molding machine and cannot continue to spread outwards. Moreover, the retained lubricating oil finally flows into the oil guiding groove 102. Most of the lubricating oil flowing down from the lower die rack 2 is surrounded by the oil retaining strip after falling onto the base 1 of the molding machine and cannot continue to spread outwards. Moreover, the retained lubricating oil finally flows into the oil guiding groove 102. Then, a part of the lubricating oil flowing down from the lower die rack 2 directly flows down along the inner wall of the pulp pool 101, but finally is blocked by the oil guiding strip 5 and guided to flow into the U-shaped oil groove 6. At the same time, the lubricating oil flowing outwards from the oil guiding groove 102 is also blocked by the oil guiding strip 5 and guided to flow into the U-shaped oil groove 6. Thus, most of the overflowing lubricating oil is concentrated in the U-shaped oil groove 6. By installing containers for receiving lubricating oil at both ends of the U-shaped oil groove 6, the lubricating oil can be collected to avoid waste. During this process, since there is an oil guiding strip 5 above the pulp pool 101 to prevent the lubricating oil from flowing down, it is possible to prevent the lubricating oil from entering the pulp pool 101 and contaminating the pulp.

[0026] In summary, the linear rail structure of the pulp molding machine with an oil collecting groove can collect all the lubricating oil overflowing from the optical axis of the hot pressing upper die through the cooperation of the retaining ring 4 and the oil guiding groove 102, and can collect most of the lubricating oil overflowing from the rack of the hot pressing lower die through the cooperation of the oil retaining strip and the oil guiding groove 102. Finally, the collected lubricating oil falls into the U-shaped oil groove 6 and is discharged into the container for storage from both ends. By installing the oil guiding strip 5 on the upper part of the two side walls of the pulp pool 101 to block the lubricating oil from flowing down and guiding the lubricating oil to fall into the U-shaped oil groove 6, it is possible to prevent the lubricating oil from leaking into the pulp pool 101.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
