[0002] Plant fiber tableware, as an environmentally friendly disposable tableware, has shown promising application prospects in replacing traditional plastic tableware in recent years. Its main raw materials are natural plant fibers, such as sugarcane bagasse and bamboo fiber, which have advantages such as biodegradability and renewability, aligning with current trends in green manufacturing and sustainable development. To achieve large-scale production of plant fiber tableware, the molding device, as one of the key pieces of equipment, plays a crucial role in the entire production process.

[0003] Existing plant fiber tableware forming equipment typically employs a thermoforming process, where moist fiber raw materials are pressed into the desired shape using upper and lower molds. During this process, factors such as mold positioning, pressure control, and demolding efficiency directly impact the quality of the finished product and production efficiency. Currently, some forming devices still have limitations in their structural design, such as insufficiently smooth demolding, misalignment during mold closure, and uneven pressure distribution. These issues all affect the forming effect and yield rate of the products.

[0004] To address the aforementioned issues, a plant fiber tableware and lunchbox molding and packaging equipment has been designed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-5 The present invention provides the following technical solution:

[0032] A plant fiber tableware and lunchbox forming and packaging equipment, comprising:

[0033] Framework 1;

[0034] The smooth rod 22 is fixedly connected to the upper end of the frame 1;

[0035] Connecting plate 23 is fixedly connected to the upper end of the guide rod 22;

[0036] The sliding rod 24 is slidably connected to the upper end of the connecting plate 23, and the lower end of the sliding rod 24 is fixedly connected to the upper plate 26, and the lower end of the upper plate 26 is fixedly connected to the upper mold 27.

[0037] The lower plate 11 is connected to the upper end of the frame 1. The upper end of the lower plate 11 is fixedly connected to the lower mold 12, which matches the upper mold 27.

[0038] The demolding mechanism includes an air outlet channel 13, a connecting pipe 17, a fixed base 18, a pneumatic sleeve 19, a push rod 20, and a fixed plate 21. The air outlet channel 13 is located at the center of its upper end. The connecting pipe 17 is connected to the side end of the air outlet channel 13. The fixed base 18 is fixedly connected to the upper end of the lower plate 11. The pneumatic sleeve 19 is connected to the side end of the fixed base 18. The connecting pipe 17 is connected to the pneumatic sleeve 19. The push rod 20 is slidably connected inside the pneumatic sleeve 19. The fixed plate 21 is fixedly connected to the side end of the push rod 20. The side end of the fixed plate 21 is connected to the frame 1.

[0039] In a specific embodiment of this utility model, when the sliding rod 24 slides up and down along the connecting plate 23 under the drive of external force, it drives the upper plate 26 and the upper mold 27 fixedly connected to it to move vertically; in this way, the upper mold 27 can move down stably and close with the lower mold 12 located on the lower plate 11, thereby realizing the hot pressing molding operation of plant fiber raw materials.

[0040] When the upper and lower molds are closed and pressure is applied, the limiting grooves 14 and limiting blocks 15 located on the sides of the upper plate 26 and the lower plate 11 cooperate with each other to guide and limit the molds. This can effectively prevent the molds from shifting or misaligning, improve the alignment and pressure distribution uniformity when the molds are closed, and thus improve the molding quality of the products.

[0041] When demolding is required after molding, high-pressure gas enters the connecting pipe 17 through the gas outlet 13 and is then delivered to the inside of the pneumatic sleeve 19. This pushes the push rod 20 to slide forward inside the pneumatic sleeve 19 and drives the demolding component to push the molded lunch box out of the lower mold 12, thus realizing the automatic demolding function.

[0042] After the push rod 20 completes the demolding action, it can return to its original position under the action of air pressure or return spring; in this way, the entire demolding mechanism completes one cycle, preparing for the next molding, and improving the continuity and automation level of equipment operation.

[0043] In addition, when the drive assembly 28 starts and drives the upper plate 26 to rise, the spring 25 can provide a certain buffering force to reduce mechanical impact; in this way, not only is the stability of equipment operation improved, but the service life of mold and the whole machine is also extended.

[0044] Please refer to the details. Figure 1-5 Both the lower plate 11 and the upper plate 26 have limit grooves 14 on their sides. Limit blocks 15 are slidably connected in the limit grooves 14. The upper end of the limit block 15 located at the lower end is connected to the lower mold 12, and the upper end of the limit block 15 is connected to the upper mold 27.

[0045] In this embodiment: when the upper mold 27 moves downward and approaches the lower mold 12 under the drive of the sliding rod 24, the limiting blocks 15 set on the upper plate 26 and the lower plate 11 slide synchronously in the limiting groove 14; in this way, the upper and lower molds can be guided to be precisely aligned along the set trajectory, preventing poor molding or mold damage due to offset.

[0046] When the upper and lower molds are closed and pressure is applied for hot pressing, the limiting block 15 is subjected to a force from the direction of the mold and generates a certain displacement buffer in the limiting groove 14; in this way, it can effectively absorb part of the impact force, while maintaining stable contact between the molds, and improving the molding and mold service life.

[0047] In this way, when the demolding mechanism is activated after molding is completed, the limit block 15 returns to its initial position with the separation action of the mold, preparing for the next molding operation; thus realizing a continuous and stable automated production process.

[0048] Please refer to the details. Figure 1-5 The upper end of the connecting plate 23 is fixedly connected to the drive component 28, and the output end of the drive component 28 is connected to the upper plate 26.

[0049] In this embodiment: when the drive component 28 starts and outputs power, its output end pushes or pulls the upper plate 26 connected to it to move up and down; in this way, the upper mold 27 can be driven to descend precisely and close with the lower mold 12 to complete the hot pressing molding action.

[0050] After the upper mold 27 completes the pressing action, the drive component 28 runs in reverse, driving the upper plate 26 and the upper mold 27 to reset upwards; in this way, it prepares for the demolding operation and the next molding, improving the working efficiency and automation of the equipment.

[0051] In this way, when the drive component 28 is used in conjunction with the spring 25, it can provide a certain buffering force before the upper mold contacts the material during its downward movement; this can prevent excessive impact from damaging the mold or fiber material, and further improve the molding quality and the stability of equipment operation.

[0052] Please refer to the details. Figure 1-5 A spring 25 is fitted onto the circumferential surface of the upper plate 26.

[0053] In this embodiment: when the drive assembly 28 drives the upper plate 26 to move downward and approach the lower mold 12, the spring 25 is in a natural state or a slightly compressed state, providing a certain buffer before the upper mold 27 contacts the material; in this way, the impact force generated at the moment the mold closes can be effectively reduced, and the fiber raw material is prevented from affecting the molding quality due to uneven force.

[0054] After the hot pressing is completed, when the drive component 28 drives the upper plate 26 to return to its original position, the spring 25 assists the upper plate 26 to quickly return to its initial position under its own elastic force. This not only improves the stability of the equipment operation, but also reduces the load pressure on the drive component and extends the service life of the equipment.

[0055] In this way, when the spring 25 is used in conjunction with other guiding components such as the guide rod 22 and the sliding rod 24, the stability of the upper mold 27 during movement can be further improved; thus, it helps to achieve high-quality and highly consistent plant fiber tableware molding effect and meet the needs of continuous production.

[0056] Please refer to the details. Figure 1-5 The upper end of the frame 1 is fixedly connected to the slide rail 2, and the slide rail 2 is slidably connected to the slider 3, which is connected to the lower plate 11.

[0057] In this embodiment: when the lower plate 11 needs to move horizontally under the action of external force, the slider 3 slides smoothly along the slide rail 2, driving the lower plate 11 and the lower mold 12 on it to move synchronously; in this way, the lower mold 12 can be accurately positioned or replaced before molding, improving the operational flexibility and automation of the equipment.

[0058] As the slider 3 slides on the slide rail 2, its structural design ensures the stability and guidance of the lower plate 11 during its movement. This effectively avoids the problem of poor closure of the upper and lower molds 12 and 27 due to offset or shaking, and further improves the molding quality and product consistency.

[0059] In this way, when the slide rail 2 is used in conjunction with the screw drive mechanism, precise drive control of the lower plate 11 can be achieved. This not only improves the automation level of the equipment operation, but also provides a reliable guarantee for the continuous and mass production of plant fiber tableware.

[0060] Please refer to the details. Figure 1-5 A connecting seat 4 is fixedly connected to the upper end of the frame 1. A lead screw 5 is rotatably connected to the side end of the connecting seat 4. A lead screw nut 6 is connected to the lead screw 5. The lead screw nut 6 is connected to the lower plate 11. A motor 8 is fixedly connected to the lower end of the frame 1. A second sprocket 9 is fixedly connected to the output end of the motor 8. A first sprocket 7 is fixedly connected to the output end of the lead screw 5. A chain 10 is rotatably connected between the first sprocket 7 and the second sprocket 9.

[0061] In this embodiment: when the motor 8 starts and outputs power through the second sprocket 9, the power is transmitted to the first sprocket 7 through the chain 10, thereby driving the lead screw 5 to rotate synchronously; in this way, the function of transmitting motor power from the bottom to the top is realized, with a compact structure and high transmission efficiency.

[0062] When the lead screw 5 rotates, the lead screw nut 6 that cooperates with it will move linearly along the axis of the lead screw, thereby driving the lower plate 11 connected to it to move horizontally on the slide rail 2; in this way, the position of the lower mold 12 can be precisely controlled, which ensures the accurate alignment of the upper and lower molds 12 and 27.

[0063] In this way, when the control system sets the stroke parameters and starts the motor 8, the lower plate 11 can automatically feed or retract. This not only improves the ease of operation and automation of the equipment, but also helps to improve the continuity and stability of the plant fiber tableware forming process.

[0064] The working principle and usage process of this utility model are as follows: First, a pre-mixed plant fiber slurry, such as bagasse or bamboo fiber, mixed with a binder, is quantitatively placed into the lower mold 12. Since the lower mold 12 is fixedly connected to the lower plate 11, and the lower plate 11 is slidably connected to the slide rail 2 via the slider 3, its position is stable and easy to adjust. The motor 8 is started, and the power is transmitted from the motor output end through the second sprocket 9 and the chain 10 to the first sprocket 7, driving the lead screw 5 to rotate. The lead screw nut 6 moves axially under the action of the rotation of the lead screw 5, and drives the lower plate 11 connected to it to slide along the slide rail 2 to the preset working position, realizing accurate positioning of the lower mold 12. The drive assembly 28 is started, pushing the upper plate 26 downward along the smooth rod 22 and the sliding rod 24, driving the upper mold 27 closer to the lower mold 12. During this process, the spring 2... 5 provides buffering force to avoid excessive impact; at the same time, the limiting block 15 slides in the limiting groove 14 to ensure the alignment and stability when the upper and lower molds are closed. After the upper and lower molds are closed, high temperature and high pressure are applied to the inside of the mold to shape the plant fiber pulp into the required lunch box shape in the mold cavity. The pressure distribution is uniform and the molding quality is high. After molding is completed, the drive component 28 runs in reverse, driving the upper mold 27 to rise and reset. Then, the gas enters the connecting pipe 17 through the gas outlet channel 13 and is transported to the inside of the pneumatic sleeve 19, pushing the push rod 20 to slide forward, thereby pushing the molded lunch box out of the lower mold 12 and completing the automatic demolding. The push rod 20 resets under the action of air pressure or spring, and the lower plate 11 returns to the initial position again under the drive of the screw drive structure, waiting for the filling of the next batch of raw materials. The entire device completes one cycle operation and can continuously carry out multiple rounds of production.

[0065] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
