[0019] Beneficial effects of the present invention:

[0020] 1. According to the previous filling material forming and processing equipment, it is usually processed by a single screw extruder, which limits its conveying and feeding characteristics. Since there is only one screw twin-screw extruder, the material cannot be fully plasticized, and only a single material can be produced, and it is not easy to adjust, which may affect the quality and production efficiency of the product. The difference is that through the twin-screw extruder, two groups are symmetrically arranged on the support component, and the granular material can be heated and melted into a liquid state. Through the dual-channel molding module, located at the front end of the two groups of twin-screw extruders, it can be used for molding and diversion of liquid materials. Through the condensation water tank, located below the dual-channel molding module, it can be used for cooling and molding operations on the material. Through the dehydration and trimming integrated molding component, located at the front end of the condensation water tank, it can be used for dehydration and trimming operations on the molding material. Through the first belt conveyor component, located along the dehydration and trimming integrated molding component, it can be used for conveying operations. Through the adjustment component, located above the first belt conveyor component, it can be used to adjust the traction. Through the second belt conveyor component, located along the first belt conveyor component, it can be conveyed, thereby improving the overall conveying operation effect.

[0021] 2. The spinneret has one hollow side and one solid side, so the material can be made hollow on one side and solid on the other side, solving the previous problem of single hardness and softness that could not be adjusted. Twin-screw extrusion can freely control the extrusion amount of both soft and hard sides (i.e., freely adjust the hardness of both sides), and can also be made into two colors.

[0022] 3. During processing, the granular materials enter the feed barrels on the two sets of twin-screw extruders through the feeder. The first drive motor drives the heating screw to rotate. The twin-screw extruder heats and melts the granular materials to 200 degrees, and heats and melts them into liquid form. The molten raw materials are squeezed into their respective double-barrel molds through the discharge pipe to improve the overall control performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In the past, a single screw could only produce one hardness and it was not easy to adjust the operation. However, with a twin screw, twin molds, and twin spinnerets, the hardness of both sides of a piece of material can be adjusted separately, which is more flexible in actual life. People who are used to sleeping on soft mattresses or hard mattresses can all meet the needs. If you want one side to be softer and the other side to be harder, you can adjust it by controlling the extrusion speed of the screw.

[0038] In the past, it was impossible to do this with a single screw, which could only produce one color. The difference is that it can produce two different colors on both sides, such as one side blue and one side transparent. This is not only beautiful, but also the colored side is more resistant to dirt than the transparent side.

[0039] It can also be set up with more functions, such as one side is ordinary and the other side is flame retardant or antibacterial or mosquito-proof, which can reduce the cost of overall flame retardancy, antibacterial or mosquito-proof production of single-screw production. The soft side can be colored and the hard side can be made transparent, so that you can tell at a glance which side is soft and hard, so you don't have to press or feel it with your hands.

[0040] Specifically, the filling materials of mattresses, pillows, and cushions have the same functions as sponges, memory foam, latex, etc.

[0041] Material features:

[0042] (1) Food contact grade raw materials, do not contain any toxic substances, non-toxic, odorless and formaldehyde-free.

[0043] The raw materials used in the mattress core have passed the FDA U.S. Food and Drug Safety Standards test, and the safety and quality are guaranteed.

[0044] 0 glue, 0 formaldehyde, 0 heavy metals, 0 carcinogenic chemicals;

[0045] (2) The fully washable polymer material is physically heated and then extruded into water for molding, and then perfectly cooled from 200° to 13° for molding. The material does not absorb water, has strong water resistance and good permeability, and can be completely washed with water. Stains can be smoothly penetrated by the water flow without residue. After the baby spits up milk or urinates, it can be washed with a faucet or shower. It is easy to clean, quick to dry, and hygienic and healthy.

[0046] (3) Dry and breathable The three-dimensional mesh support structure with no contact winding creates a highly breathable air microcirculation system. 90% of the mattress is air. The air can follow the body's movements to form an air flow inside, which can discharge the moisture in the mattress and the sweat secreted by the body along with the air flow. It is not easy to accumulate moisture, can effectively prevent stuffiness, and is not easy to breed mites and bacteria. Compared with slow-rebound mattresses, it is more breathable, will not be stuffy, and will not cause night sweats. It can reduce the risk of suffocation for infants;

[0047] (4) The elastic touch supports the human body. The three-dimensional structure of air fiber weaving can evenly disperse the pressure of the human body into tens of thousands of support points, fully support and relieve fatigue. It also has a super high recovery rebound force, which reduces the burden of turning over when the human body is sleeping, and can respond quickly to any movement of the body. The material can adapt to the human body curve and provide support for the head, shoulders, waist, hips and legs;

[0048] (5) Excellent durability and not easy to deform. After hundreds of raw material ratio experiments, we created a high molecular weight polyethylene propylene butene octene copolymer elastomer, which is more elastic, more supportive, more durable and more scientific than the ordinary PE / POE material. In the compression hardness index and antioxidant resistance experiments, it is better than the standards of ordinary mattresses and pillows, durable and highly elastic, not easy to deform. In the Japanese KAKEN 80,000 compression test, the thickness reduction rate is only 5.6%;

[0049] (6) Environmentally friendly materials recycling mattresses use recyclable material polyethylene, which can be recycled over time and made into other plastic products.

[0050] The biggest advantages of this material are that it is washable, breathable (air permeability is 6267mm / s, pressure is 100pa, test area is 100㎝2), highly elastic, formaldehyde-free, food contact grade, and not easy to collapse (750 Newton force acts on the same point 80,000 times, the collapse rate is only 5.6%)

[0051] Any color can be customized:

[0052] (1) The amount of masterbatch added is about 2 to 4%.

[0053] (2) Two colors can be achieved on the same material

[0054] That is: one side is transparent + one side is colored or both sides are different colors.

[0055] Producible thickness: 1cm~20cm.

[0056] Producible thickness: 30 density ~ 150 density

[0057] The silk forms that can be produced are:

[0058] (1).Pure hollow core

[0059] (2). Pure solid core

[0060] (3). One side is hollow core + one side is solid core

[0061] Different shapes can be customized:

[0062] By changing the arrangement and distribution of the spinneret openings and cooperating with the underwater shaping sleeve, products of different shapes can be manufactured.

[0063] (1). Wave shape (can be used as a cervical pillow)

[0064] (2). Cylindrical (can be used as a cervical pillow)

[0065] (3). Semicircular (can be used as a foot pillow)

[0066] (4). Triangle (can be used as a seat cushion, baby spit-up pad, waist support, etc.)

[0067] (5). Oval (can be used as a pillow)

[0068] (6). U-shaped (can be used as a pet mat)

[0069] (7).L type (can be used as pet mat)

[0070] 1. Antibacterial (with test report) against Escherichia coli and Staphylococcus aureus.

[0071] 2. One side is hollow and the other side is solid (the solid side is softer and the hollow side is harder, that is, one side is soft and the other side is hard, and the hardness can be adjusted according to your sleeping habits), which solves the previous problem of single hardness and inability to adjust.

[0072] 3. Upgraded to white, solving the previous problem of yellowing due to fear of sun exposure.

[0073] 4. Twin-screw extrusion can freely control the extrusion amount of both soft and hard sides (i.e. freely adjust the softness and hardness of both sides), and can also be made into two colors.

[0074] Types of production materials: (non-mixed production, each material is used separately)

[0075] 1.POE
