[0002] Pulp molding tableware is tableware made from pulp as the main raw material through a specific process. Traditional pulp molding tableware molding equipment generally suffers from the process defect of pulp layering and deposition during the mixing stage. Due to the lack of effective material lifting function in the mixing mechanism, the degradation agent and pulp are not mixed evenly, which directly affects the performance stability of the biodegradable material. Existing mixing devices are prone to mechanical wear on the inner wall of the container during operation. The residual pulp adhering to the mixing chamber not only increases raw material loss, but also affects the continuous operation efficiency of the equipment due to solidification and agglomeration. In the molding section, conventional molding equipment generally adopts mechanical ejection demolding method. This method is prone to deformation of thin-walled tableware structure, and the mold replacement process is cumbersome. Especially when producing irregularly shaped tableware, it is necessary to stop the machine and disassemble the entire pressure mechanism, which seriously restricts the flexible production capacity of multiple varieties.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5 As shown, this embodiment provides a biodegradable pulp molding tableware forming device, including a pulp tank 1 with a built-in mixing chamber. The bottom inner wall of the pulp tank 1 is provided with an installation groove 7. An anti-wear mixing component 2 is fixedly installed inside the installation groove 7. The upper part of the anti-wear mixing component 2 is located inside the mixing chamber, which can fully mix the pulp raw materials and degradation agent inside the mixing chamber. A lower mold 3 and a fixing frame 4 are fixedly installed on the top of the pulp tank 1. An air-blowing pressing molding component 5 is fixedly installed on the inner wall of the top of the fixing frame 4. The air-blowing pressing molding component 5 is located above the lower mold 3. Connecting pipes 6 are fixedly installed on both sides of the pulp tank 1. The other end of the connecting pipe 6 passes through and is installed on one side of the lower mold 3. The connecting pipe 6 connects the lower mold 3 and the pulp tank 1 together.

[0022] In actual use, after the operator puts the pulp raw material and degradation agent into the pulp tank 1, the wear-resistant stirring component 2 is activated, which enables the pulp raw material and degradation agent inside the pulp tank 1 to be fully stirred and mixed. A pump body is set on the outside of the connecting pipe 6, which can pump the raw material inside the pulp tank 1 into the lower mold 3. After the pulp is injected into the lower mold 3 through the connecting pipe 6, the air-blowing pressing molding component 5 is activated. The air-blowing pressing molding component 5 presses down vertically, which can accurately fit and form with the lower mold 3. After pressing, the air-blowing pressing molding component 5 can also use airflow to assist in demolding, which improves the efficiency of tableware forming.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the wear-resistant mixing assembly 2 includes a motor 201 for driving and a mounting shaft 202. The motor 201 is fixedly installed inside the mounting groove 7, and the mounting shaft 202 is installed at the output end of the motor 201. A mixing frame 204 is fixed to the outside of the mounting shaft 202, and a conveying blade 203 is fixed to the outside of the mounting shaft 202. The mixing frame 204 is located outside the conveying blade 203. A slot 205 is provided on the outside of the mixing frame 204, and a rod 206 is fixed to the bottom of the slot 205. The rod 206 improves the stability between the mixing frame 204 and the silicone scraper 207. The silicone scraper 207 for cleaning the inner wall of the mixing chamber of the slurry tank 1 is engaged inside the slot 205. A groove is provided at the bottom of the silicone scraper 207, and the rod 206 is inserted into the groove.

[0024] In use, the motor 201 drives the mounting shaft 202 to rotate, and the conveying blades 203 and the mixing frame 204 rotate with the mounting shaft 202. The mixing frame 204 mixes the pulp raw materials and degradation agent inside the pulp tank 1, while the conveying blades 203 can turn the pulp deposited at the bottom of the mixing chamber upward, avoiding the problem of uneven mixing caused by pulp deposition and improving the mixing effect. During the mixing process, the silicone scraper 207, with the cooperation of the insertion rod 206 and the slot 205, can always move in close contact with the inner wall of the mixing chamber to scrape and clean the pulp adhering to the inner wall of the mixing chamber. This effectively prevents waste and cleaning problems caused by pulp adhering to the inner wall of the mixing chamber, improves the cleanliness and efficiency of the equipment, and the silicone scraper 207 is soft and can prevent the mixing frame 204 from damaging the coating of the inner wall of the mixing chamber.

[0025] As a technical optimization solution of this utility model, specifically as follows: Figure 5As shown, the air-blowing press molding assembly 5 includes a telescopic part 501 for height adjustment and a mounting bracket 502. The top of the telescopic part 501 is fixedly installed on the inner wall of the top of the fixed bracket 4. The top of the mounting bracket 502 is fixed to the bottom of the telescopic part 501. A blower 507 is installed on one side of the mounting bracket 502, and an air duct 508 is fixedly installed on one side of the blower 507. A guide rod 503 is fixedly installed on the top of the mounting bracket 502. The top of the guide rod 503 is located above the fixed bracket 4. Under the action of the guide rod 503, the upper mold 506 and the lower mold 3 can be driven to fit precisely. The bottom of the mounting bracket 502 has an opening. A first mounting ring 504 with a threaded groove on the inner side is fixed inside the opening. A second mounting ring 505 with a threaded protrusion on the outer side is installed inside the first mounting ring 504. The first mounting ring 504 and the second mounting ring 505 are threadedly connected. The bottom of the second mounting ring 505 is fixed to the upper mold 506. The bottom of the upper mold 506 has a ventilation opening.

[0026] In use, the telescopic part 501 drives the mounting frame 502 to move up and down according to the set stroke. The guide rod 503 guides and limits the up and down movement of the mounting frame 502 to ensure the stability of the mounting frame 502 during movement and prevent deviation or shaking. When the upper mold 506 cooperates with the lower mold 3 to press and shape the slurry, the blower 507 is started, and external air is drawn into the mounting frame 502 through the air duct 508. Then, the air is evenly blown into the tableware through the ventilation port at the bottom of the upper mold 506, so that the tableware is subjected to uniform force during the molding process and can be more easily removed from the mold after molding. This not only improves the efficiency of tableware forming but also ensures the quality of the formed tableware. In addition, when it is necessary to produce tableware of different specifications, the operator only needs to rotate the second mounting ring 505 to separate the second mounting ring 505 from the first mounting ring 504, so that the upper mold 506 can be easily removed from the mounting bracket 502 and replaced with an upper mold 506 of other specifications. Then, the second mounting ring 505 and the first mounting ring 504 are re-threaded and fixed to complete the replacement operation of the upper mold 506. The whole replacement process is simple and quick, without the need to stop the machine to disassemble the entire pressure mechanism, which greatly improves the flexibility and maintenance efficiency of the equipment.

[0027] In this embodiment, the mounting rack 502 is configured as an openable frame, which can place dry ice inside the mounting rack 502 according to the tableware forming requirements, thereby reducing the temperature of the air inside the mounting rack 502 and improving the efficiency of tableware production.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
