[0042] like Figure 1 to Figure 7 As shown, this embodiment provides a rapid prototyping egg tray production device, including

[0043] A rapid prototyping egg tray production device comprises: a frame 1 and a wheel hub 2 rotatably arranged on the frame 1, a molding die 3 arranged on the wheel hub 2 and a pulp box 4 arranged on the frame 1; a stirring blade 5 rotatably arranged at the bottom of the pulp box 4; a stirring rod 6 rotatably arranged on the frame 1 and located in the pulp box 4, the rotation axis of the stirring rod 6 is perpendicular to the rotation axis of the stirring blade 5, and the stirring rod 6 is located above the stirring blade 5.

[0044] In this embodiment, the frame 1 serves as the basic skeleton of the entire equipment, carrying all components and maintaining their stability, providing support and installation points; the hub 2 is the core rotating component of the equipment, and a forming mold 3 is installed on the hub 2, and its rotation allows the mold to pass through each production station in turn to achieve continuous and rapid forming of the egg tray; the forming mold 3 is designed with a groove shape of the egg tray; the pulp box 4 is used to store and supply the pulp required for making the egg tray; a stirring blade 5 is installed at the bottom of the pulp box 4 to keep the pulp evenly suspended and prevent precipitation. The stirring blade 5 is rotatably arranged at the bottom of the pulp box 4, and the pulp is continuously stirred by rotating motion to ensure that the pulp fibers are evenly dispersed, avoid precipitation, and ensure the quality of egg tray forming; the rotation axis of the stirring rod 6 is perpendicular to the axis of the stirring blade 5 and is located above the stirring blade 5. The stirring rod 6 performs horizontal stirring inside the pulp box 4, and combined with the vertical stirring of the stirring blade 5, a three-dimensional stirring effect is formed, which more effectively prevents the pulp fibers from agglomerating and further improves the uniformity and fluidity of the pulp.

[0045] In this embodiment, when the wheel hub 2 rotates, the forming mold 3 passes under the pulp box 4, receives a certain amount of pulp filling, and then undergoes dehydration and drying steps at a subsequent station, and then the mold removal device removes the formed egg tray from the forming mold 3, and finally forms an egg tray. The mold removal device is a structure in the prior art, and is not described in detail in this embodiment, and is not shown in the drawings.

[0046] Optionally, there are several stirring rods 6 , and the method further includes: a rotating shaft 7 is rotatably arranged on the frame 1 and located in the pulp box 4 , and several stirring rods 6 are circumferentially distributed around the rotating shaft 7 , and the stirring rods 6 are rotatably connected to the pulp box 4 via the rotating shaft 7 .

[0047] In this embodiment, the stirring rods 6 are arranged in a plurality to increase the stirring area, improve the stirring efficiency, and ensure that the pulp is mixed more fully and evenly in the pulp box 4; the plurality of stirring rods 6 are fixed on the peripheral side of the rotating shaft 7 in a circumferential distribution manner. Such a layout enables the stirring rods 6 to cover a larger space in the pulp box 4 during rotation, and stir the pulp in an all-round and non-dead angle manner, further improving the uniformity of pulp mixing. The arrangement of the rotating shaft 7 provides a unified rotation center and support structure for the plurality of stirring rods 6. When the rotating shaft 7 rotates, all the stirring rods 6 will rotate synchronously around the axis of the rotating shaft 7 to jointly complete the stirring operation of the pulp. The driving structure of the stirring rods 6 is simplified, and the overall operation stability of the equipment is improved. By increasing the number of stirring rods 6, introducing the rotating shaft 7, and optimizing the distribution of the stirring rods 6, the efficiency and uniformity of pulp stirring are significantly enhanced, which is conducive to improving the quality and production efficiency of egg tray products. At the same time, the structural design is more compact and reasonable, which is conducive to the long-term stable operation and maintenance of the equipment.

[0048] Optionally, there are a plurality of stirring blades 5 , and the plurality of stirring blades 5 are distributed in an array at the bottom of the pulp box 4 .

[0049] In this embodiment, the stirring blades 5 are arranged in a number to increase the stirring area, improve the stirring efficiency, and ensure that the pulp is more fully and evenly mixed at the bottom of the pulp box 4. Several stirring blades 5 are distributed in the form of an array at the bottom of the pulp box 4 to ensure that each area at the bottom of the pulp box 4 can be effectively stirred, reduce the stirring blind area, enhance the dispersion effect of the pulp fiber, avoid local precipitation, and ensure the uniformity of the pulp as a whole. Multiple stirring blades 5 work together with the stirring rod 6 to form a three-dimensional stirring system that is linked up and down. The stirring blades 5 are responsible for the longitudinal stirring at the bottom, and the stirring rod 6 is responsible for the lateral stirring. The two cooperate with each other to stir the pulp more comprehensively and deeply, improve the stirring effect, and ensure the supply of high-quality pulp required for egg tray production. By increasing the number of stirring blades 5 and adopting an array distribution method, the stirring efficiency and uniformity of the pulp at the bottom of the pulp box 4 are effectively improved, and a complementary three-dimensional stirring system is formed with the stirring rod 6, which helps to improve the quality and production efficiency of egg tray products.

[0050] Optionally, it also includes: a scraper 8 is slidably arranged in the pulp box 4, the scraper 8 has an avoidance opening 801 and a scraping end 802, the rotating shaft 7 and a plurality of stirring rods 6 all pass through the avoidance opening 801, and the scraping end 802 abuts against the inner wall of the pulp box 4.

[0051] In this embodiment, the scraper 8 is used to clean the pulp attached to the inner wall of the pulp box 4 to prevent the accumulation of pulp from affecting the normal operation of the equipment and the quality of the egg tray. The scraper 8 is provided with an avoidance opening 801, and the rotating shaft 7 and the plurality of stirring rods 6 all pass through the avoidance opening 801, so that the scraper 8 will not interfere with the rotating shaft 7 and the stirring rods 6 during the sliding process, ensuring that the scraper 8 works smoothly and the normal operation of the stirring system is ensured. The scraper 8 has scraping ends 802 on both sides, which are tightly abutted against the inner wall of the pulp box 4. When the scraper 8 slides, the scraping ends 802 will move along the inner wall of the pulp box 4 to scrape off the attached pulp, keep the inner wall of the pulp box 4 clean, and avoid equipment blockage or egg tray quality degradation caused by pulp hardening or accumulation. The scraper 8 is set in the pulp box 4 by sliding, and the avoidance opening 801 is used to avoid the rotating shaft 7 and the stirring rods 6, and the scraping ends 802 scrape off the pulp attached to the inner wall of the pulp box 4, which reduces the problem of pulp accumulation and helps to improve the stability of egg tray production and product quality.

[0052] Optionally, it also includes: a screw 9 is rotatably set on the frame 1 and located in the pulp box 4, the screw 9 rotates with the rotating shaft 7, and the scraper 8 is threadedly matched with the screw 9; the first roller 10 is set on the screw 9 and located outside the frame 1; the second roller 11 is set on the rotating shaft 7, located outside the frame 1 and on the same side as the first roller 10; the belt 12 is wound around the first roller 10 and the second roller 11.

[0053] In this embodiment, the lead screw 9 is connected with the scraper 8 by threaded matching, that is, the scraper 8 is provided with a threaded hole matching the lead screw 9, and a spiral transmission relationship is formed between the two. A first roller 10 is provided on the lead screw 9, and the first roller 10 is located outside the frame 1. A second roller 11 is also provided on the rotating shaft 7, and the second roller 11 is located outside the frame 1 and on the same side as the first roller 10. The belt 12 is wound around the first roller 10 and the second roller 11 to form a closed transmission loop. When the rotating shaft 7 rotates, the first roller 10 is driven to rotate by the belt 12, thereby driving the lead screw 9 to rotate. Since the lead screw 9 is threadedly matched with the scraper 8, the rotation of the lead screw 9 will cause the scraper 8 to move linearly along the axial direction of the lead screw 9, thereby achieving the scraping action on the inner wall of the pulp box 4. By adding the lead screw 9, the first roller 10, the second roller 11 and the belt 12, a set of linkage mechanism is constructed, so that the sliding of the scraper 8 is directly related to the rotation of the rotating shaft 7. When the rotating shaft 7 drives the stirring rod 6 to stir the pulp, the belt 12 drives the lead screw 9 to rotate, thereby driving the scraper 8 to slide in the pulp box 4 to remove the pulp attached to the inner wall. The original power source of the equipment is used to realize the automation of the action of the scraper 8, which not only simplifies the equipment structure and reduces the difficulty of maintenance, but also improves the overall operation efficiency of the equipment and the continuity of egg tray production.

[0055] In this embodiment, the conveying member 14 can be a spiral conveying member 14. The two ends of the pulp inlet pipe 13 are connected to the pulp box 4 and the external pulp source respectively. The function of the pulp inlet pipe 13 is to smoothly and continuously introduce the prepared pulp from the external pulp source into the pulp box 4, so as to provide a stable supply of raw materials for egg tray molding. A rotating conveying member 14 is arranged inside the pulp inlet pipe 13. The function of the conveying member 14 is to push the pulp in the pulp inlet pipe 13 forward through its own rotation, effectively overcome gravity and friction resistance, and ensure that the pulp smoothly enters the pulp box 4. The use of the conveying member 14 can reduce the retention or blockage of pulp in the pulp inlet pipe 13, ensure the continuity and stability of pulp supply, and help improve the production efficiency of egg trays.

[0056] Optionally, there are multiple forming dies 3 , and the multiple forming dies 3 are distributed on the wheel hub 2 in an array.

[0057] In this embodiment, the forming molds 3 are set to be several, and multiple egg trays can be manufactured at the same time, which significantly improves the production efficiency of the equipment. Several forming molds 3 are distributed on the wheel hub 2 in an array form. This layout design makes full use of the circumferential space of the wheel hub 2, so that the forming molds 3 can pass through each station in turn during the rotation process to perform continuous and synchronous egg tray forming operations. The array distribution method is conducive to the compact design of the equipment, and it is also convenient for unified management and maintenance of the forming molds 3.

[0058] Optionally, it also includes: a driving member 15 arranged on the frame 1, and the driving member 15 is used to drive the rotating shaft 7 to rotate; a spray arm 16 is arranged on the frame 1, located above the pulp box 4, and the spray arm 16 has a plurality of spray ports 1601 distributed in an array.
