[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper as raw material. It uses special molds on a molding machine to shape paper products into a certain shape. It has four major advantages: the raw material is waste paper, including cardboard, waste cardboard, and waste white edge paper, which are widely available; its production process is completed by pulping, adsorption molding, drying and shaping, etc., which is harmless to the environment; and it can be recycled and reused.
[0003] Paper pulp tableware is made by vacuum adsorption molding of paper pulp using molds, drying, and further processing. It can replace metal and plastic tableware for people to use. Currently, the shaping of paper pulp tableware generally relies on the mating of upper and lower molds to achieve the drying and shaping of paper pulp tableware.
[0004] However, in existing pulp molding equipment, the upper and lower molds are usually fixed and disassembled by bolts. In order to meet the diverse needs of consumers for tableware size, shape and function, it is usually necessary to change the mold to adapt to the production of tableware of different sizes and shapes. Therefore, the upper and lower molds need to be replaced. However, the traditional structure makes the disassembly and installation of the upper and lower molds cumbersome and time-consuming, which increases the downtime of the equipment and reduces the production efficiency.

[0017] This utility model has the following beneficial effects:
[0018] 1.

Therefore, they should not be construed as limitations on the utility model.
[0034] Please see Figures 1-7 As shown, this utility model is an automated demolding equipment for pulp molded tableware, including a workbench 1, a positioning frame 2 fixedly installed on the workbench 1, a heating plate 3 fixedly installed on the upper surface of the workbench 1, a lower mold 4 slidably sleeved on the heating plate 3, an upper mold 7 set on the positioning frame 2, two positioning grooves 14 extending from their lower surfaces on the upper surface of the workbench 1, vertical blocks 15 slidably connected in the positioning grooves 14, and mounting plates 32 fixedly connected to the lower surfaces of the two vertical blocks 15;
[0035] The lower mold 4 is provided with a first disassembly mechanism, which facilitates the replacement of the lower mold 4 with different sizes and shapes.
[0036] The positioning frame 2 is provided with a second disassembly mechanism, and the upper mold 7 is mounted on the second disassembly mechanism. The second disassembly mechanism facilitates the replacement of the upper mold 7 of different sizes and shapes.
[0037] The two vertical blocks 15 are respectively provided with a grouting mechanism and a demolding mechanism. The mounting plate 32 is provided with a moving mechanism, which is used to drive the grouting mechanism and the demolding mechanism to move back and forth, so that the moving mechanism drives the grouting mechanism to grout and the demolding mechanism to demold the pulp molded tableware.
[0038] In one embodiment, the first disassembly mechanism includes a motor 19, which is fixedly connected to the left side surface of the positioning frame 2. The lower surface of the lower mold 4 is provided with a support groove, and the lower mold 4 is slidably mounted on the heating plate 3 through the support groove. The positioning frame 2 is n-shaped, and the outer surfaces of the two adjacent vertical blocks of the positioning frame 2 are provided with mounting grooves 20. The outer surfaces of the left and right sides of the worktable 1 are provided with connecting grooves 21.
[0039] The first disassembly mechanism further includes a bidirectional threaded rod 17, which is rotatably sleeved on the workbench 1. Both the left and right ends of the bidirectional threaded rod 17 are rotatably connected to the inner wall of the mounting groove 20. The left end of the bidirectional threaded rod 17 rotatably passes through the left side surface of the positioning frame 2. The left end of the bidirectional threaded rod 17 is fixedly connected to the rotation output shaft of the motor 19. Two fixing blocks 18 are threadedly sleeved at the two opposite threads of the bidirectional threaded rod 17. The fixing blocks 18 are slidably connected to the mounting groove 20 and the connecting groove 21. The fixing blocks 18 are L-shaped. Fixing grooves 16 are opened on the outer surfaces of both sides of the lower mold 4. The fixing grooves 16 are slidably connected to the cross blocks of the fixing blocks 18.
[0040] In addition, in specific applications, the lower mold 4 is slidably mounted on the heating plate 3. The heating plate 3 is equipped with heating wires. When the heating plate 3 heats, it transfers heat to the lower mold 4. After the pulp is injected into the lower mold 4, the first push rod 5 is activated to drive the upper mold 7 to move downward so that the upper mold 7 and the lower mold 4 can be closed, thereby drying and shaping the pulp into tableware.
[0041] The lower mold 4 is slidably mounted on the heating plate 3. The starting motor 19 drives the bidirectional threaded rod 17 to rotate. The rotation of the bidirectional threaded rod 17 synchronously drives the two fixed blocks 18 to move closer or further apart. When the two fixed blocks 18 move closer together, the horizontal block of the fixed block 18 slides into the fixed groove 16, thereby fixing the lower mold 4 and preventing it from moving. Conversely, when the starting motor 19 drives the two fixed blocks 18 to move further apart, the horizontal block of the fixed block 18 slides out of the fixed groove 16, completing the disassembly of the lower mold 4. This facilitates the disassembly and replacement of the lower mold 4, allowing for the production of lower molds 4 that can produce tableware of different sizes and shapes. The replacement is convenient, labor-saving, efficient, and quick, thereby improving the processing efficiency of pulp molded tableware and increasing the practicality and flexibility of the automated demolding equipment for pulp molded tableware.
[0042] In one embodiment, the second disassembly mechanism includes a first push rod 5, which is fixedly mounted on the upper surface of the positioning frame 2. The telescopic end of the first push rod 5 slides through the lower surface of the horizontal plate of the positioning frame 2. A mounting block 6 is fixedly connected to the telescopic end of the first push rod 5. Four sliding grooves 9 extending from the lower surface of the mounting block 6 are provided on the upper surface of the mounting block 6. Sliding blocks 10 are slidably connected in the sliding grooves 9. A positioning rod 12 is fixedly connected between the inner walls of the front and rear sides of the sliding grooves 9. The sliding blocks 10 slide... The upper mold 7 has four fixed hook grooves 8 on its upper surface, and a fixed hook block 13 is fixedly connected to the lower surface of the positioning rod 12. The fixed hook block 13 is slidably connected to the fixed hook groove 8 and is adapted to the fixed hook groove 8. A positioning spring 11 is fixedly connected to the outer surfaces of the adjacent sides of the sliding block 10 on both the front and rear sides. The end of the positioning spring 11 away from the sliding block 10 is fixedly connected to the inner wall of the sliding groove 9. The positioning spring 11 is slidably sleeved on the corresponding outer surface of the positioning rod 12.
[0043] In addition, in specific applications, when installing the upper mold 7, the upper mold 7 is moved upward and close to the mounting block 6, and the fixing hook block 13 is slid into the fixing hook groove 8. With the cooperation of the fixing hook block 13 and the fixing hook groove 8, the sliding blocks 10 on the front and rear sides will move closer to each other, so as to stretch the positioning spring 11, thereby causing the positioning spring 11 to be stretched and deformed. When the upper mold 7 moves upward until its upper surface is in contact with the lower surface of the mounting block 6, the fixing hook block 13 is completely slid into the fixing hook groove 8 and the lower surface of the fixing hook block 13 contacts the bottom wall of the fixing hook groove 8. At this time, the fixing hook block 13 is pushed into the fixing hook groove 8 under the action of the release force of the positioning spring 11, so that the fixing hook block 13 and the fixing hook groove 8 are engaged with each other, thereby fixing the upper mold 7 on the mounting block 6 and completing the installation of the upper mold 7.
[0044] During disassembly, push the sliding blocks 10 on both the front and rear sides to bring them closer together. During this process, the positioning spring 11 is compressed, causing it to deform. The displacement of the sliding blocks 10 synchronously drives the fixed hook block 13 to slide within the fixed hook groove 8. When the sliding blocks 10 on both the front and rear sides approach each other until the upper surface of the fixed hook block 13 disengages from the top wall of the fixed hook groove 8, the fixed hook block 13 is released from its engagement with the sliding groove 9. The upper mold 7 then slides downward, moving it away from the mounting block 6, thus completing the disassembly of the upper mold 7. The disassembly is convenient and efficient, facilitating the replacement of the upper mold 7. This allows for the replacement of upper molds 7 that can produce tableware of different sizes and shapes, ensuring that the upper mold 7 and the lower mold 4 are compatible and easy to replace. This increases the practicality and flexibility of the automated demolding equipment for pulp molded tableware.
[0045] In one embodiment, the moving mechanism includes a support plate 33, which is fixedly connected to the lower surface of the workbench 1. A third push rod 30 is fixedly mounted on the support plate 33, and the telescopic end of the third push rod 30 is fixedly connected to the vertical block 15 located on the front side.
[0046] In addition, in specific applications, since the support plate 33 is fixedly connected to the lower surface of the workbench 1, when the support plate 33 is activated, the telescopic end of the third push rod 30 will push the vertical block 15 located on the front side to move back and forth. Since the two vertical blocks 15 are fixedly connected by the mounting plate 32, the activation of the third push rod 30 will synchronously drive the two vertical blocks 15 and the mounting plate 32 to move back and forth.
[0047] In one embodiment, the grouting mechanism includes a pulp pipe 24, which is fixedly connected to the upper surface of the vertical block 15 located at the rear. A plurality of conveying heads 25 communicating with the interior of the pulp pipe 24 are fixedly connected to the pulp pipe 24, and the conveying heads 25 are inclined.
[0048] In addition, in specific applications, a solenoid valve is installed on the conveying head 25, and the left end of the pulp pipe 24 is connected to the pulp storage tank. When the vertical block 15 moves back and forth, the vertical block 15 located on the rear side synchronously drives the pulp pipe 24 fixed on it to move back and forth, so that the pulp pipe 24 synchronously drives the conveying head 25 to move back and forth. When the conveying head 25 moves forward, the conveying head 25 is displaced to the upper side of the lower mold 4. At this time, the pulp can flow into the mold groove in the lower mold 4 through the pulp pipe 24 and the conveying head 25. The amount of pulp injected can be controlled by the solenoid valve on the conveying head 25, so that manual pulp injection is not required, which is more labor-saving.
[0049] In one embodiment, the demolding mechanism includes positioning tubes 28. The upper side of the vertical block 15 located at the front is U-shaped. Two positioning tubes 28 are fixedly connected to the upper side of the vertical block 15 located at the front. An air pipe 22 is rotatably sleeved inside the two positioning tubes 28. A second push rod 29 is fixedly connected to the upper surface of the mounting plate 32. A rack 23 is fixedly connected to the telescopic end of the second push rod 29. A gear 27 is fixedly sleeved on the outer surface of the air pipe 22. The gear 27 is located between the two positioning tubes 28. The gear 27 meshes with the rack 23. A connecting pipe 26 communicating with the interior of the air pipe 22 is fixedly connected to the outer surface of the air pipe 22. A suction cup 31 is fixedly installed at the end of the connecting pipe 26 away from the air pipe 22. The suction cup 31 communicates with the interior of the connecting pipe 26.
[0050] In addition, in specific applications, an air pump is installed at the left end of the air pipe 22. The suction end of the air pump is fixedly connected to the left end of the air pipe 22. When the vertical block 15 moves back and forth, the vertical block 15 located on the front side synchronously drives the positioning tube 28 to move back and forth, thereby synchronously driving the air pipe 22 to move back and forth, so that the air pipe 22 synchronously drives the connecting tube 26 and the suction cup 31 to move back and forth. In the initial state, the suction cup 31 is in a rearward state. When the air pipe 22 drives the suction cup 31 to move backward to a suitable position, the second push rod 29 is activated. The extension end of the second push rod 29 drives the rack 23 to move up and down. Because the rack 23 meshes with the gear 27... Therefore, at this time, the rack 23 drives the gear 27 to rotate, and the rotation of the gear 27 synchronously drives the air pipe 22 fixed to it to rotate. The rotation of the air pipe 22 synchronously drives the connecting pipe 26 and the suction cup 31 to rotate. During the rotation, the suction cup 31 moves into the mold groove on the lower mold 4. At this time, starting the air pump can drive the suction cup 31 to adsorb the pulp molded tableware in the mold groove. Then, starting the second push rod 29 drives the air pipe 22 to rotate in the opposite direction, thereby demolding the pulp molded tableware from the mold groove, thus realizing the automatic demolding of pulp molded tableware, which is safer, more efficient, and saves more manpower, thereby increasing the practicality of the automatic demolding equipment for pulp molded tableware.
[0051] Through the above technical solution, 1. When the starting motor 19 drives the two fixed blocks 18 to move away from each other, the horizontal block of the fixed block 18 slides out of the fixed groove 16, completing the disassembly of the lower mold 4. This facilitates the disassembly and replacement of the lower mold 4, allowing for the replacement of the lower mold 4 to produce tableware of different sizes and shapes. The replacement is convenient and labor-saving, and efficient and quick, thereby improving the processing efficiency of pulp molded tableware and increasing the practicality and flexibility of the automated demolding equipment for pulp molded tableware.
[0052] 2. When the sliding blocks 10 on the front and rear sides move closer to each other until the upper surface of the fixed hook block 13 separates from the top wall of the fixed hook groove 8, the fixed hook block 13 is released from the engagement with the sliding groove 9, and the upper mold 7 slides down, moving away from the mounting block 6, thereby completing the disassembly of the upper mold 7. The disassembly is convenient and efficient, and it is easy to replace the upper mold 7, so that the upper mold 7 can be replaced to produce tableware of different sizes and shapes. This makes the upper mold 7 and the lower mold 4 compatible with each other, and the replacement is convenient and labor-saving, thereby increasing the practicality and flexibility of the automated demolding equipment for pulp molded tableware.
[0053] 3. By starting the air pump, the suction cup 31 can be driven to adsorb the pulp molded tableware in the mold groove. Then, the second push rod 29 is started to drive the air pipe 22 to rotate in the opposite direction, thereby demolding the pulp molded tableware from the mold groove. This achieves automatic demolding of pulp molded tableware, which is safer, more efficient, and saves more manpower, thus increasing the practicality of the automatic demolding equipment for pulp molded tableware.
