Description

Technical Field

[0001] The invention relates to the technical field of processing equipment, in particular to a molding device for a plastic packaging bowl. Background Art

[0002] With the rise of the plastics industry and the continuous advancement of plastic processing technology, plastic packaging bowls have gradually been favored by the market due to their lightness, durability, and easy processing. From the initial simple shape and single material to today's diversified designs and the application of environmentally friendly materials, the development of plastic packaging bowls has witnessed the rapid development of human science and technology and industry. Plastic packaging bowls, as the name suggests, refer to bowl-shaped containers made of plastic materials for holding food. According to different materials, shapes, uses, etc., plastic packaging bowls can be divided into many types, such as disposable plastic bowls, reusable plastic bowls, plastic bowls with lids, transparent plastic bowls, etc. Plastic packaging bowls, as a widely used type of tableware, are characterized by lightness, durability, and low cost, and are widely used in takeout, fast food, family gatherings and other occasions.

[0003] In the production process of plastic packaging bowls, the raw materials (such as plastic particles) often contain a certain amount of moisture. If these moisture are not removed, defects such as bubbles and shrinkage holes will be generated during the injection molding process, seriously affecting the appearance and performance of the product. Therefore, the main function of the dryer is to remove the moisture in the raw materials by heating and ventilation to ensure that the dryness of the raw materials meets the injection molding requirements. When drying the plastic raw materials, the plastic raw materials are easy to pile up together, resulting in the device being unable to dry the plastic raw materials evenly and effectively. When drying the plastic raw materials, the evaporated moisture will drip into the device, which is easy to cause damage to the device. At the same time, there are more particles and dust in the air. When the airflow enters the box, the particles and dust in the air cause the plastic packaging bowls to easily have molding defects, and there are molding defects and defective product rates caused by environmental factors.

[0009] Preferably, the fan is installed on a side surface of the box body, the air inlet is opened above one side of the fan, and the air outlet is opened below the other side of the fan.

[0010] Preferably, the filter is installed on one side of the air outlet, and the activated carbon adsorption plate is installed on one side of the filter.

[0011] Preferably, the hot air duct is connected to one side of the activated carbon adsorption plate, and the exhaust port is opened on one side of the hot air duct.

[0012] Preferably, the moisture discharge port is symmetrically opened at the left and right ends of the upper part of the box body. Beneficial Effects

[0013] 1. In the forming equipment for the plastic packaging bowl, the plastic raw material enters into the feed pipe through the feed port, and enters into the discharge port through the feed pipe, and then enters into the storage tray through the discharge port, and the discharge port is installed above the storage tray, so that more plastic raw materials can be put in when the plastic raw materials are dried. While the plastic raw materials are input, the motor drives the sleeve to rotate on the connecting rod, thereby driving the rotation of the scraper. The rotation of the scraper can evenly spread the plastic raw materials entering into the storage tray in the storage tray, effectively preventing the plastic raw materials from piling up when the plastic raw materials are dried, resulting in the device being unable to evenly and effectively dry the plastic raw materials, thereby ensuring that the device can evenly dry the plastic raw materials.

[0014] 2. The forming equipment for the plastic packaging bowl, when the plastic raw materials are being dried, the moisture in the raw materials will evaporate, and the evaporated moisture will enter the water storage tray. When a certain amount of water is stored in the water storage tray, the water in the water storage tray will enter the water tank through the water inlet pipe, and the water in the water tank will be discharged through the drain port. Therefore, when the plastic raw materials are being dried, the evaporated moisture is prevented from dripping into the device, which may cause damage to the device. At the same time, the collected water can be recycled and reused in an appropriate manner.

[0015] 3. After the plastic raw materials are input into the storage tray, the forming equipment of the plastic packaging bowl generates airflow through the fan, and the generated airflow is transported to the air outlet through the air inlet, and the air outlet transmits the airflow into the box. When the airflow enters the box, it will contact the filter and the activated carbon adsorption plate. Therefore, the particles and dust in the air are filtered through the filter to ensure the purity of the airflow entering the forming equipment, reduce the defects of the plastic packaging bowl forming caused by impurities, and when the airflow is transported, some harmful gases or odors will be generated in the air. Therefore, the activated carbon adsorption plate can effectively remove these harmful gases and odors by using the strong adsorption performance of activated carbon to achieve ventilation. The filter and activated carbon adsorption plate help to improve the yield and product quality of plastic packaging bowls, reduce molding defects and defective product rates caused by environmental factors, and then use the fan to circulate hot air through the raw materials to evaporate and discharge the moisture in the raw materials, thereby greatly improving the molding rate of plastic packaging bowls. In addition, since plastic raw materials easily absorb moisture in the air during processing, if this moisture is not removed in time, it will cause quality problems such as bubbles, shrinkage, and deformation in the plastic products during the molding process. The moisture inside the equipment can be effectively discharged through the moisture discharge port to ensure that the plastic raw materials are processed in a dry environment, thereby improving the molding quality of the product.

The discharge port 3 is connected with the feed port 2 through the feed pipe 2-1 on the side. The discharge port 3, the feed pipe 2-1 and the feed port 2 are in a connected structure.

[0029] When in use, the plastic raw material enters the feed pipe 2-1 through the feed port 2, and enters the discharge port 2 through the feed pipe 2-1, so that the plastic raw material enters the storage tray 7 through the discharge port 3, and the discharge port 3 is installed above the storage tray 7, so that more plastic raw materials can be put in when the plastic raw materials are dried. While the plastic raw materials are input, the motor 4 drives the sleeve ring 8 to rotate on the connecting rod 5, thereby driving the rotation of the scraper 9. The rotation of the scraper 9 can evenly spread the plastic raw materials entering the storage tray 7 in the storage tray 7, effectively preventing the plastic raw materials from piling up when the plastic raw materials are dried, causing the device to The plastic raw material cannot be dried evenly and effectively, so the device is ensured to be able to dry the plastic raw material evenly. When the plastic raw material is dried, the water in the raw material will evaporate, and the evaporated water will enter the water storage tray 6. When a certain amount of water is stored in the water storage tray 6, the water in the water storage tray 6 will enter the water tank 11 through the water inlet pipe 10, and the water in the water tank 11 will be discharged through the drain port 12.

After the material tray 7, an air flow is generated by the fan 13, and the generated air flow is transported to the air outlet 15 through the air inlet 14, and the air outlet 15 transmits the air flow to the box body 1. When the air flow enters the box body 1, it will contact the filter screen 16 and the activated carbon adsorption plate 17. Therefore, the particles, dust, etc. in the air are filtered through the filter screen 16 to ensure that the air flow entering the molding equipment is high in purity, and the molding defects of the plastic packaging bowl caused by impurities are reduced. When the air flow is transported, some harmful gases or odors will be generated in the air. Therefore, the activated carbon adsorption plate 17 uses the strong adsorption performance of activated carbon to effectively remove these harmful gases and odors, so as to achieve the effect of passing through the filter screen 16 and The activated carbon adsorption plate 17 helps to improve the yield and product quality of plastic packaging bowls, reduce molding defects and defective product rates caused by environmental factors, and then use the fan 13 to circulate hot air through the raw materials to evaporate and discharge the moisture in the raw materials, thereby greatly improving the molding rate of plastic packaging bowls. Since plastic raw materials easily absorb moisture in the air during processing, if this moisture is not removed in time, it will cause quality problems such as bubbles, shrinkage, and deformation in the plastic products during the molding process. The moisture inside the equipment can be effectively discharged through the dehumidification port 20 to ensure that the plastic raw materials are processed in a dry environment, thereby improving the molding quality of the product.
