Description

Technical Field

[0001] The invention relates to the technical field of packaging material production, and in particular to a pearl cotton raw material stirring device and a stirring method. Background Art

[0002] Pearl cotton is a polyethylene foam with a non-cross-linked closed-cell structure. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene grease. It has the advantages of water-proof and moisture-proof, shock-proof, sound-proof, heat-insulating, good plasticity, and recycling. The raw materials of pearl cotton include molten resin, butane, talcum powder, anti-shrinkage agent and other additives. All raw materials need to be mixed evenly before foaming. Since the raw materials of pearl cotton are light in weight, after adding multiple raw materials, the raw materials first added are deposited at the bottom of the stirring device and cannot be stirred evenly, resulting in quality problems of the foaming material due to uneven mixing.

[0033] It is understandable that the stirring container is provided with a raw material adding inlet so as to facilitate adding the pearl cotton raw material into the stirring container.

[0034] At the same time, the stirring container and the mixing container are connected to the corresponding air suction port and air filling port of the air pump through a reversing valve. Usually, a two-position four-way electromagnetic reversing valve is used to connect the stirring container, the mixing container and the air pump.

[0035] That is to say, the air pipe interface of the stirring container is connected to an interface of the reversing valve through an air pipe, the air pipe interface of the mixing container is connected to an interface of the reversing valve through an air pipe, the air pump's air inlet is connected to an interface of the reversing valve, and the air pump's air exhaust port is connected to an interface of the reversing valve.

[0036] The stirring container and the mixing container are connected to the same side of the reversing valve, and the air inlet and the air exhaust port of the air pump are on one side of the reversing valve. Therefore, through the reversing of the reversing valve, the air pump can pump the gas in the mixing container into the stirring container, or pump the gas in the stirring container into the mixing container.

[0037] Since the resin in the pearl cotton raw material needs to remain in liquid state, a heating element, such as an electric heating wire or a heat exchanger, is provided in the stirring container.

[0038] In order to reduce the heat loss of the pearl cotton raw material, a heat preservation layer is usually provided outside the stirring container, and the mixing container is arranged inside the stirring container.

[0039] To further ensure the uniformity of stirring, the stirring tubes are evenly distributed along the circumference of a preset axis.

[0040] Preferably, the distance from the lower end of the plurality of stirring tubes to the bottom of the stirring container increases axially, so that the lower end of each stirring tube is located in the EPE raw material liquid at a different depth, and the EPE raw material liquid at a different depth can be extracted to further improve the stirring efficiency and the uniformity of the stirring.

[0041] Preferably, the outer side wall of the stirring tube is provided with a plurality of protrusions, so as to disturb the flowing pearl cotton raw material liquid through the protrusions, thereby further improving the stirring efficiency and the uniformity of the stirring.

[0042] Preferably, the plurality of protrusions are staggered along the length direction of the stirring tube, which can further improve the stirring efficiency and the uniformity of stirring.

[0043] Preferably, the inner diameter of the stirring tube is larger at the top and smaller at the bottom to reduce the impact of the pearl cotton raw material on the mixing container.

[0044] The pearl cotton raw material stirring device provided in this embodiment has a closed mixing container at the upper end of a closed stirring container, and a plurality of stirring tubes extending toward the bottom of the stirring container at the lower end of the mixing container, and both the stirring container and the mixing container are provided with air pipe interfaces, which can force the liquid pearl cotton raw material in the stirring container to flow alternately to the mixing container and the stirring container through the stirring tube through a pump, so that the pearl cotton raw materials are evenly mixed.

[0045] Therefore, this embodiment can avoid the deposition or stratification of the pearl cotton raw materials, and ensure that the pearl cotton raw materials are stirred evenly to avoid quality problems caused by uneven mixing.

[0046] Example 2

[0047] This embodiment provides a method for stirring a pearl cotton raw material, based on the pearl cotton raw material stirring device described in Example 2, comprising the following steps:

[0048] S1. Add the pearl cotton raw material into the stirring container until the lower ends of all the stirring tubes are in the pearl cotton raw material liquid;

[0049] S2. Heat the raw materials through the heating element to ensure that the raw materials of the pearl cotton remain in liquid state;

[0050] S3. Control the action of the reversing valve to alternately circulate the gas in the stirring container and the mixing container.

[0051] In this embodiment, the reversing valve is used to control the direction of the air pump outlet, and the gas in the stirring container and the mixing container are circulated alternately, forcing the liquid pearl cotton raw material in the stirring container to flow alternately to the mixing container and the stirring container through the stirring tube, so that the pearl cotton raw material is mixed evenly.

[0052] Therefore, this embodiment can avoid the deposition or stratification of the pearl cotton raw materials, and ensure that the pearl cotton raw materials are stirred evenly to avoid quality problems caused by uneven mixing.
