Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton production equipment, specifically a pearl cotton raw material foaming machine. Background Technology

[0002] Pearl cotton, also known as expanded polyethylene (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. Due to its unique closed-cell structure, it effectively isolates moisture, while the internal independent air bubbles act as a cushion, reducing vibration and noise. This bubble structure gives pearl cotton excellent thermal insulation properties. It is also easy to process into various shapes and sizes, and it is not easily broken, possessing high strength and durability. As a new type of environmentally friendly material, it is recyclable, reducing environmental pollution. Through the foaming process, low-density polyethylene resin forms countless independent, closed air bubbles. These bubbles give pearl cotton unique physical and chemical properties, such as water and moisture resistance, shock absorption, and sound insulation. Furthermore, foamed pearl cotton has a lower density but improved strength and toughness, making it widely applicable in packaging and protective applications. The foaming process also reduces the amount of raw materials used. This reduces production costs by adjusting the amount of material used. The lightweight nature of EPE foam also lowers transportation costs. Furthermore, by adjusting the foaming process, EPE foam products with different densities, hardness, and thicknesses can be produced to meet the needs of different customers. Currently, most foaming equipment on the market involves a crucial uniform mixing process before the raw materials are fed into the EPE foam machine to ensure the superior quality of the final product. However, the feed hoppers of these devices often use a cylindrical structure design. This design has a significant drawback: when various raw materials are poured into the hopper, any clumps formed due to incomplete mixing will settle and accumulate on the support base due to their own gravity. These clumps are then fed into the EPE foam machine through the feed pipe without further dispersion. These undispersed and insufficiently mixed clumps will undoubtedly have an adverse effect on subsequent production processes and the quality of the finished product, leading to a decline in product quality. For example, "Utility Model..." CN220841152U describes a foaming machine for EPE foam raw materials. The side wall of the supporting pedestal and the surface of the pedestal are in contact. When the supporting pedestal is placed on the pedestal surface, the discharge port of the mixing tank is blocked. At this time, the EPE foam raw materials on the supporting pedestal can be stirred and mixed. After uniform mixing, the supporting pedestal is moved upwards, separating from the contacting pedestal surface, opening the discharge port. The uniformly mixed EPE foam raw materials then enter the foaming machine body through the gap between the supporting pedestal and the pedestal surface, preventing the EPE foam raw materials from entering the foaming machine before being uniformly mixed, thus affecting the quality of the finished product. A rotary motor controls a rotating cylinder to drive a rotating shaft and rotating blades to stir the EPE foam raw materials. The rotating cylinder drives a driven gear, a rotating rod, and spiral blades to rotate through a main gear, simultaneously stirring the EPE foam raw materials and transporting the lower layer of EPE foam raw materials upwards, preventing uneven mixing of the EPE foam raw materials. While existing technologies may already address the above problems, this invention aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a pearl cotton raw material foaming machine, comprising: a stirring shell, a supporting base and a foaming machine body, wherein the foaming machine body is connected to the supporting base, the stirring shell is installed on the supporting base, a mixing and agitating structure is installed on the stirring shell, and a raw material anti-sinking auxiliary component is installed inside the stirring shell;

[0004] The mixing and agitation structure includes: a main power chamber, a main power rotor, a feeding port, a main drive shaft, several single-sided stirring blades, a closed plate support, an electric telescopic rod, and a closed sealing plate;

[0005] The main power chamber is installed on the mixing shell, the main power rotor is installed in the main power chamber and connected to the main drive shaft, the material inlet is installed on the mixing shell, a plurality of single-sided mixing blades are respectively installed on the main drive shaft, the sealing plate bracket is installed on the mixing shell, the electric telescopic rod is installed on the sealing plate bracket, the sealing plate is installed on the electric telescopic rod, the mixing shell is equipped with a shell slide rail, and the sealing plate is installed on the mixing shell through the shell slide rail;

[0006] It should be noted that, as described above, the pearl cotton raw material is fed into the mixing shell through the inlet, driving the main power rotor in the main power chamber to rotate, which in turn drives the main drive shaft and several single-sided mixing blades to rotate. This causes the pearl cotton raw material to be continuously stirred and mixed in the mixing shell, and with the help of the raw material anti-sinking auxiliary components, it will not clump together. After the stirring and mixing is completed, the electric telescopic rod on the closed plate support is driven to extend and retract, thereby moving the closed sealing plate and fully exposing the finished product discharge port on the mixing shell, so that the mixing shell and the foaming machine body are interconnected. The fully mixed pearl cotton raw material flows into the foaming machine body through the finished product discharge port under the action of gravity for foaming treatment.

[0007] Preferably, the raw material anti-sinking auxiliary component includes: a secondary auxiliary rotor, a transmission gearbox, several branch stirring shafts, and several auxiliary stirring rollers;

[0008] The secondary auxiliary rotor is installed in the support base and is connected to the transmission gearbox. Several branch stirring shafts are respectively installed in the stirring housing through bearings and are respectively connected to the transmission gearbox. Several auxiliary stirring rollers are respectively installed on several branch stirring shafts.

[0009] It should be noted that, as described above, when the single-sided stirring blade rotates and agitates the pearl cotton material inside the stirring shell, it drives the secondary auxiliary rotor in the support base to rotate, which in turn causes the transmission gearbox to drive multiple branch stirring shafts to rotate. The multiple auxiliary stirring rollers on the multiple branch stirring shafts rotate one after another, agitating the nearby pearl cotton material, thereby filling the dead corners that the multiple single-sided stirring blades inside the stirring shell cannot reach, making the pearl cotton material more thoroughly agitated.

[0010] Preferably, the injection port is provided with a dust cover;

[0011] Preferably, the main power compartment is provided with a maintenance and inspection port;

[0012] Preferably, the mixing shell is provided with a finished product discharge port;

These optimization measures lay a solid foundation for subsequent foaming processing, resulting in a more ideal foamed EPE foam and a significant improvement in overall quality.

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-3 As shown, a foaming machine for pearl cotton raw materials includes: a mixing shell 1, a supporting base 2, and a foaming machine body 3. The foaming machine body 3 is connected to the supporting base 2. The mixing shell 1 is installed on the supporting base 2. A mixing and agitating structure is installed on the mixing shell 1. A raw material anti-sinking auxiliary component is installed inside the mixing shell 1. The mixing and agitating structure includes: a main power chamber 4, a main power rotor 5, a feeding port 6, a main drive shaft 7, several single-sided mixing blades 8, a closed plate support 9, an electric telescopic rod 10, and a closed sealing plate 11.
