[0002] Disposable expanded polystyrene (EPE) foam is a new type of environmentally friendly packaging material. It is made of low-density polyethylene resin through physical foaming, creating countless independent air bubbles. This material overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also exhibits good chemical resistance. Therefore, EPE foam is an ideal alternative to traditional packaging materials and is widely used in various industrial and consumer sectors. Disposable expanded polystyrene foam is produced through foaming and extrusion molding.

[0022] like Figures 1 to 4As shown in the figure, this embodiment of the disposable foamed pearl cotton production device includes a foaming machine body 1, which has a foaming cavity inside. A front end plate 2 is provided at one end of the foaming machine body 1, and a foaming head 21 is provided in the middle of the front end plate 2. The front end plate 2 and the foaming machine body 1 are sealed and assembled together by an assembly mechanism 3. A cooling mechanism 4 is provided on the side of the foaming head 21 away from the foaming machine body 1. The cooling mechanism 4 has a cooling channel, and the center of the foaming head 21 is at the same height as the center of the cooling channel. The foaming machine body 1 has a feed inlet 5 on its top and a pusher plate 6 inside its foaming cavity. A hydraulic cylinder 7 is located at the end of the foaming machine body 1 away from the front end plate 2. The output end of the hydraulic cylinder 7 is connected to one side of the pusher plate 6 through a hydraulic rod, thereby realizing a combination of air cooling and water cooling in the production of disposable foamed pearl cotton. This increases the air cooling contact area, improves cooling efficiency, and enhances the production efficiency of disposable foamed pearl cotton. It also enables the front end plate 2 to be sealed and fixedly assembled on the foaming machine body 1, ensuring a firm and reliable assembly that is easy to disassemble and replace.

[0023] Specifically, the assembly mechanism 3 includes an assembly plate 31, a sealing groove 32, a sealing platform 33, and assembly bolts 34. The end of the foaming machine body 1 away from the hydraulic cylinder 7 is open. The assembly plate 31 is provided on the outer circumference of the end of the foaming machine body 1 away from the hydraulic cylinder 7. The side of the assembly plate 31 near the front end plate 2 is provided with a sealing groove 32. The side of the front end plate 2 near the assembly plate 31 is provided with a sealing platform 33. The sealing platform 33 is located inside the sealing groove 32. Both the assembly plate 31 and the sealing platform 33 are provided with assembly screw holes. The assembly plate 31 and the sealing platform 33 are fixedly installed by the assembly bolts 34 in the assembly screw holes, so as to achieve the sealed and fixed assembly of the front end plate 2 on the foaming machine body 1. The front end plate 2 and the foaming head 21 on the foaming machine body 1 are easy to disassemble, install, and replace.

[0024] Furthermore, the assembly plate 31, the sealing groove 32, and the sealing platform 33 are all arranged in a ring structure, and several assembly bolts 34 are evenly distributed at equal intervals. The assembly bolts 34 are arranged through the sealing platform 33 to securely assemble the front end plate 2.

[0025] Furthermore, the cooling mechanism 4 includes an outer cooling cylinder 41, an inner cooling cylinder 42, a cooling chamber 43, an air-cooling inlet 44, a return air inlet 45, a cooling pipe 46, and a circulating fan 47. The inner cooling cylinder 42 is located inside the outer cooling cylinder 41, and a cooling channel is located inside the inner cooling cylinder 42. The cooling chamber 43 is formed between the outer cooling cylinder 41 and the inner cooling cylinder 42. An air-cooling inlet 44 is located at one end of the inner cooling cylinder 42, and a return air inlet 45 is located at the other end of the inner cooling cylinder 42. The air-cooling inlet 44 is connected to the output end of the circulating fan 47 on the outer cooling cylinder 41 through the cooling pipe 46, and the input end of the circulating fan 47 is connected to the return air inlet 45 through the cooling pipe 46. The cooling pipe 46 is located inside the cooling chamber 43. The outer cooling cylinder 41 is equipped with a semiconductor refrigeration chip with the cooling surface facing the cooling chamber 43. The semiconductor refrigeration chip cools the interior of the cooling chamber 43. Under the action of the circulating fan 47, the air in the cooling pipe 46 that has been cooled by the cooling chamber 43 enters the cooling channel of the inner cooling cylinder 42 in a ring shape through the air cooling port 44. The air in the cooling channel enters the cooling pipe 46 through the return air port 45. That is, under the action of the circulating fan 47, cooling air is formed between the air cooling port 44 and the return air port 45 and flows in the cooling channel for cooling the foamed pearl cotton in one-time foaming molding.

[0026] Furthermore, the inner wall of the inner cooling cylinder 42 between the air cooling inlet 44 and the return air inlet 45 is provided with air guide plates 48. There are several air guide plates 48. During the cooling air circulation, the air at the inner edge of the cooling channel encounters the air guide plates 48 and is guided to form a central airflow flowing towards the middle area of ​​the cooling channel, so that the cooling airflow circulating in the cooling channel repeatedly contacts the disposable foamed pearl cotton product.

[0027] Furthermore, both the air-cooling inlet 44 and the return air inlet 45 are arranged in a ring shape. The air-cooling inlet 44 has a large air supply area and uniform air supply in the cooling channel. The air guide plate 48 is arranged in a ring-shaped horn structure. The air-cooling inlet 44 is located inside the inner cooling cylinder 42 at the end away from the foaming head 21. The air supply in the air-cooling inlet 44 flows towards one end of the foaming head 21, resulting in a large cooling temperature difference space.

[0028] Furthermore, the cooling pipe 46 is arranged in a spiral structure, and the cooling pipe 46 has a large cooling contact area.

[0029] The usage method of this embodiment is as follows: Material is injected into the foaming cavity of the foaming machine body 1 through the feed port 5. Under the action of the hydraulic cylinder 7, the pusher plate 6 is pushed to move inside the foaming machine body 1, and the disposable foamed pearl cotton molding material is extruded and formed from the foaming head 21 for the foaming and molding production of disposable foamed pearl cotton. Under the traction of the existing traction equipment, the formed disposable foamed pearl cotton passes through the cooling channel and the cooling mechanism 4. Under the action of the circulating fan 47, the air in the cooling pipe 46 that has been cooled and cooled by the cooling cavity 43 enters the cooling channel of the inner cooling cylinder 42 in a ring shape through the air cooling port 44. The air in the cooling channel enters the cooling pipe 46 through the return air port 45. That is, under the action of the circulating fan 47, cooling air is formed between the air cooling port 44 and the return air port 45 and flows in the cooling channel. During the process, the air at the edge of the cooling channel is guided by the air guide plate 48, forming a central airflow that flows towards the middle area of ​​the cooling channel. This allows the cooling airflow circulating in the cooling channel to repeatedly contact the disposable foamed pearl cotton product, achieving a combination of air cooling and water cooling in the production of disposable foamed pearl cotton. This increases the air cooling contact area, improves cooling efficiency, and enhances the production efficiency of disposable foamed pearl cotton. The assembly plate 31 and sealing groove 32 on the foaming machine body 1 cooperate with the sealing plate 33 on the front end plate 2. The sealing plate 33 is sealed and inserted into the sealing groove 32. The assembly bolts 34 fix the sealing plate 33 to the assembly plate 31, achieving a sealed and fixed assembly of the front end plate 2 on the foaming machine body 1. The assembly is firm and reliable, and the front end plate 2 and the foaming head 21 on the foaming machine body 1 are easy to disassemble and replace.
