[0002] Polyethylene foam, also known as EPE (Electronic Polyethylene Foam), is a non-crosslinked closed-cell structure and a new environmentally friendly packaging material. It is composed of countless independent bubbles created through physical foaming of low-density polyethylene ester. This overcomes the shortcomings of conventional foams, such as fragility, deformation, and poor recovery.

[0003] EPE pearl cotton needs to be processed using a cooling and foaming device. For example, the Chinese patent document CN220864579U proposes an EPE pearl cotton circulating cooling and foaming device, which discharges the foamed pearl cotton raw material through the discharge port, and then shapes the discharged raw material through the pearl cotton mold. The style of the pearl cotton mold can be freely changed according to demand to improve practicality.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] This utility model provides a technical solution, please refer to Figure 1 、 Figure 2 and Figure 3 An EPE pearl cotton circulating cooling foaming device includes: an extruder 1, a discharge die 2 and a circulating water cooling mechanism 3. The extruder 1 is a common extrusion device structure in the prior art. The top of the extruder 1 is connected to a silo 11, and the interior of the silo 11 is polished and processed. The silo 11 can store materials.

[0027] The discharge mold 2 is assembled on the outside of the discharge port of the extruder 1. The discharge mold 2 is a molding mold used for the processing and production of EPE pearl cotton in the prior art. The circulating water cooling mechanism 3 is assembled on the right side of the extruder 1. The circulating water cooling mechanism 3 includes a cooling box 31. The interior of the cooling box 31 can store cooling water. The right side of the cooling box 31 is connected to a water pump 32, and the water pump 32 can pump cooling water into the interior of the water cooling tower 33.

[0028] The water outlet of the water pump 32 is connected to the water cooling tower 33 through a bellows. The water cooling tower 33 can cool the cooling water. The water cooling tower 33 is a cooling water tower structure commonly used in the prior art. The outside of the water cooling tower 33 is connected to a water outlet pipe 34, and the inside of the water outlet pipe 34 is equipped with a butterfly valve. The water cooling tower 33 and the cooling box 31 are both assembled on the right side of the extruder 1. The water outlet pipe 34 can discharge the water source inside the water cooling tower 33 into the inside of the cooling box 31. The top of the water cooling tower 33 is connected to the air pump 4, and the outside of the air pump 4 is connected to the discharge mechanism 5 through a bellows.

[0029] See also Figure 4 and Figure 5 The discharging mechanism 5 includes a square box 51, which can provide air flow. The outside of the square box 51 is fixedly connected to a long arm 41, and the long arm 41 is connected to the water cooling tower 33. The long arm 41 can support and fix the square box 51. The square box 51 is connected to the air pump 4. The inside of the square box 51 is equipped with an impeller group 53. The impeller group 53 includes a shaft, which is connected to the runner 61. The junction of the shaft and the square box 51 is connected through a sealed bearing. The outside of the shaft is sleeved with an impeller, which can be driven by airflow. The inner bottom of the square box 51 is fixedly connected with a guide plate 52, and the guide plate 52 is polished. The guide plate 52 can guide the airflow to drive the impeller group 53 to move.

[0030] The left side of the square box 51 is connected to a curved pipe 54, and the other end of the curved pipe 54 is connected to an air collecting box 55. The air collecting box 55 can collect the airflow. The air collecting box 55 is assembled inside the discharge mold 2, and the one-way valve tube 56 is connected to the mold cavity inside the discharge mold 2. The air collecting box 55 cooperates with the one-way valve tube 56 to exhaust the inside of the mold cavity, and the one-way valve tube 56 is designed to be inclined, so that the airflow flows inside the mold cavity. The bottom of the air collecting box 55 is evenly distributed with one-way valve tubes 56. The one-way valve tubes 56 can only exhaust in one direction and cannot take in air, so as to prevent raw materials from entering the inside of the one-way valve tube 56.

[0031] Both ends of the impeller group 53 are connected to an impact mechanism 6, which includes a rotating wheel 61. The rotating wheel 61 can drive the hollow column 62 to move.

The spring 64 can drive the impact arm 63 to impact the discharge mold 2, and the impact arm 63 can enter the interior of the hollow column 62.

[0032] In this solution, the raw materials are first poured into the interior of the silo 11, the extruder 1 is started to process the raw materials, and the raw materials are discharged into the interior of the cooling box 31 through the discharge die 2, and the water pump 32 is started to extract the water source inside the cooling box 31 and cool it through the water cooling tower 33, and then discharged into the interior of the cooling box 31 through the outlet pipe 34. In this way, the EPE pearl cotton is circulated and cooled for foaming.

[0033] Start the air pump 4 to pump gas into the interior of the square box 51, and then enter the interior of the curved pipe 54 through the guide plate 52, and then discharge into the mold cavity inside the discharge mold 2 through the air collecting box 55 and the one-way valve pipe 56, so as to discharge the material inside the mold cavity. At the same time, the air flow drives the impeller group 53 to rotate, and then drives the runner 61 to rotate, and knocks the discharge mold 2 through the hollow column 62, the impact arm 63 and the impact arm 63, so that the discharge mold 2 produces a slight shake, thereby increasing the smoothness of the material during discharge;

[0034] During the circulating cooling and foaming process of EPE pearl cotton, the additional discharging mechanism 5 automatically drives the material inside the mold cavity of the discharging mold 2 to discharge the material, and prevents the material from adhering to and blocking the inside of the discharging mold 2, affecting the discharging, and at the same time prevents the material from being blocked together, reducing the quality of the finished product. Through the additional impact mechanism 6, when the discharging mechanism 5 drives the discharging mold 2 to discharge the material through the airflow, the flow force of the airflow can be recovered to knock on the discharging mold 2, causing the discharging mold 2 to vibrate slightly, and cooperating with the discharging mechanism 5 to greatly improve the smoothness of the discharging.
