They have the characteristics of light weight, heat insulation, sound absorption, shock absorption, and better dielectric properties than base resins. They are widely used. Almost all kinds of plastics can be made into foam plastics, and foaming has become an important field in plastic processing.
[0003] For example, the uniform foaming device for the production of foam plastic insulation boxes disclosed in the authorization announcement number CN215703483U includes a foaming device body with an opening at the top, a gas pressure telescopic rod, and a fan impeller. The beneficial effect of adopting the above technical solution is that the first connecting rod connected by the gas pressure telescopic rod drives the fan impeller to rotate, and the external air is discharged into the foaming device body, so that the air circulates, and the contact amount between the resin and the air is increased during foaming.
[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;
[0005] Although the above patent allows air circulation and increases the contact amount between resin and air during foaming, the external air directly enters the foaming box without being filtered, and the impurities in the air will be mixed into the foaming box, resulting in defects in the quality of the foam manufactured later.

[0027] In this embodiment, during foaming, the raw materials are fed in from the feed port 18, and then the motor 3 is started. At this time, the internal stirring rod 4 will control the stirring plate 5 to stir the raw materials in the foaming box 1, and allow air to mix therein for foaming. When the stirring rod 4 rotates, the transmission rod 16 at the top of the stirring rod 4 drives the first pulley 17 to rotate, and the first pulley 17 drives the second pulley 701 to rotate synchronously through the belt. After the second pulley 701 rotates, it drives the fan blades 702 at the top to stir at high speed, so that the external air enters from the filter element 9, and then passes through the filter screen 703 and is discharged into the foaming box 1. The air is double-filtered by the filter element 9 and the filter screen 703 in turn, which can prevent debris and dust from entering with the air, resulting in defects in the quality of the foam produced later.
[0028] like Figure 4 As shown, optical axes 10 are fixedly installed on both sides of the bottom end of the inner housing 6, a sealing plate 11 is movably mounted between the outsides of the two optical axes 10, a hollow floating block 12 is fixedly installed in the middle of the bottom end of the sealing plate 11, and springs 13 are arranged between the sealing plate 11 and both sides of the inner housing 6, and the springs 13 are movably arranged outside the optical axes 10;
[0029] In this embodiment, when too much material is poured into the foaming box 1, the hollow float 12 rises synchronously with the liquid level of the material. After the hollow float 12 floats, it lifts the sealing plate 11 until the sealing plate 11 seals the filter screen 703 at the bottom end of the inner shell 6. This can prevent excessive material from overflowing into the inner shell 6, thereby achieving the purpose of facilitating sealing.
[0030] like Figure 3 As shown, the output shaft of the motor 3 is located at one end of the transmission housing 2 and is provided with a driving gear 14, and a driven gear 15 is provided on the right side of the transmission housing 2, the driven gear 15 is meshed with the driving gear 14, and the bottom end of the driven gear 15 is fixedly connected to a first pulley 17 through a transmission rod 16, and the bottom end of the first pulley 17 is fixedly connected to the stirring rod 4;
[0031] In this embodiment, when the motor 3 is started, the driving gear 14 is controlled to rotate. After the driving gear 14 rotates, it drives the driven gear 15 engaged on the other side to rotate in the opposite direction.

[0034] Working principle: During foaming, the raw materials are fed in from the feed port 18, and then the motor 3 is started. At this time, the internal stirring rod 4 will control the stirring plate 5 to stir the raw materials in the foaming box 1, and allow air to mix therein for foaming. When the stirring rod 4 rotates, the transmission rod 16 at the top of the stirring rod 4 drives the first pulley 17 to rotate, and the first pulley 17 drives the second pulley 701 to rotate synchronously through the belt. After the second pulley 701 rotates, it drives the fan blade 702 at the top to stir at high speed, so that the external air enters from the filter element 9, and then passes through the filter screen 703 and is discharged into the foaming box 1. The air is double-filtered by the filter element 9 and the filter screen 703 in turn. When too much material is poured into the foaming box 1, the hollow floating block 12 rises synchronously with the liquid level of the material. After the hollow floating block 12 floats, it lifts the sealing plate 11 until the sealing plate 11 closes the filter screen 703 at the bottom of the inner shell 6. This can avoid excessive material input, which causes it to overflow into the inner shell 6.
