Description

Technical Field

[0001] The utility model belongs to the technical field of EVA production, and particularly relates to an EVA foam cotton production device. Background Art

[0002] Ethylene-vinyl acetate copolymer (EVA) is a general-purpose polymer, which is flammable and has no irritating smell when burning. When the content of vinyl acetate in EVA is less than 20%, it can be used as a plastic. EVA has good low-temperature resistance, and its thermal decomposition temperature is relatively low, about 230 °C. As the molecular weight increases, the softening point of EVA rises, the processability and the surface gloss of plastic parts decrease, but the strength increases, and the impact toughness and environmental stress cracking resistance improve. EVA is slightly worse than polyethylene and polyvinyl chloride in terms of chemical resistance and oil resistance, and the change is more obvious with the increase of vinyl acetate content.

[0046] This embodiment provides an EVA foam production device, including:

[0047] Fixing frame 1;

[0048] Melting material barrel 2, which is rotatably installed on the fixing frame 1 and includes an opening structure and a discharge port 201;

[0049] Heating mechanism 3, which is installed on the fixing frame 1 for heating the melting material barrel 2;

[0050] Rotating mechanism, which is installed on the fixing frame 1 for controlling the rotation of the melting material barrel 2;

[0051] Stirring mechanism, which is used for stirring the materials in the melting material barrel 2;

[0052] Extrusion mechanism, which is installed on the fixing frame 1 and is used for extruding the materials discharged from the discharge port 201.

[0053] In this technical solution, EVA resin is mixed with a foaming agent, a plasticizer, and other additives in a certain proportion, and then added into the melting material barrel 2 through the opening structure of the melting material barrel 2. The heating mechanism 3 heats the melting material barrel 2 so that the raw materials in the melting material barrel 2 are melted, and then the stirring mechanism works to stir various raw materials. At the same time, the rotating mechanism controls the rotation of the melting material barrel 2, driving the materials in the melting material barrel 2 to flow. The rotation direction of the melting material barrel 2 is opposite to the stirring rotation direction of the stirring mechanism, causing a turbulent flow in the fluid in the melting material barrel 2, strengthening the stirring effect, and enabling various raw materials to be mixed together faster. After the mixing is completed, the materials in the melting material barrel 2 are discharged through the discharge port 201 into the extrusion mechanism, and then extruded by the extrusion mechanism onto the production mold for use.

[0054] In summary, the heating mechanism 3 is used to heat and melt various raw materials in the melting barrel 2, the stirring mechanism is used to stir and mix various raw materials in the melting barrel 2, and at the same time, the rotating mechanism controls the rotation of the melting barrel 2 and is used in cooperation with the stirring mechanism, effectively enhancing the stirring effect, accelerating the material mixing speed, and improving the production efficiency.

[0055] Embodiment 2:

[0056] This embodiment provides an EVA foam cotton production device. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0057] Furthermore, it further includes a capping mechanism, and the capping mechanism includes:

[0058] A moving cover plate 4, and the moving cover plate 4 is used to cover the opening of the melting barrel 2;

[0059] A lifting assembly, which is installed on the fixed frame 1 and is used to control the moving cover plate 4 to move along the first direction Z;

[0060] Among them, the stirring mechanism is installed on the moving cover plate 4.

[0061] Furthermore, the lifting assembly includes:

[0062] A first driving member 5, and the first driving member 5 is installed on the fixed frame 1;

[0063] A connecting rod 6, one end of the connecting rod 6 is connected to the output end of the first driving member 5, and the other end is connected to the moving cover plate 4;

[0064] Among them, the first driving member 5 is used to control the connecting rod 6 to move along the first direction Z.

[0065] Furthermore, the stirring mechanism includes:

[0066] A stirring paddle 7, and the stirring paddle 7 is rotatably installed on the moving cover plate 4;

[0068] In this technical solution, the first driving member 5 can be a cylinder. The cylinder is installed on the fixed frame 1, the output end of the cylinder is connected to the connecting rod 6, and the piston of the cylinder extends to push the connecting rod 6 to move downward along the first direction Z. The connecting rod 6 drives the moving cover plate 4 to move downward along the first direction Z, so that the moving cover plate 4 can cover the opening of the melting barrel 2.

[0069] The second driving member 8 can be a motor, which is installed on the movable cover plate 4. After the movable cover plate 4 moves downward along the first direction Z to a specified position to seal the melting material barrel 2, the motor drives the stirring paddle 7 to rotate to stir and mix the materials in the melting material barrel 2.

[0070] Through this structural design, it effectively prevents the materials in the melting material barrel 2 from splashing out during the stirring and mixing process, avoiding material waste and environmental pollution; in addition, the stirring paddle 7 can be lifted and lowered with the movable cover plate 4, facilitating the staff to clean the stirring paddle 7 during the subsequent production.

[0071] Embodiment 3:

[0072] This embodiment provides an EVA foam production device. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0073] Furthermore, the capping mechanism further includes:

[0074] A feed hopper 9, and the feed hopper 9 is installed on the movable cover plate 4.

[0075] Through this structural design, when all the materials in the melting material barrel 2 are discharged from the discharge port 201 into the extrusion mechanism and various raw materials need to be added to the melting material barrel 2 again, the raw materials can be directly added to the melting material barrel 2 through the feed hopper 9. In addition, when the production and preparation are completed, cleaning liquid can also be added to the melting material barrel 2 through the feed hopper 9, and in cooperation with the stirring operation of the stirring mechanism, the inside of the melting material barrel 2 can be cleaned.

[0076] In summary, without the lifting component controlling the movable cover plate 4 to move upward along the first direction Z, raw materials or cleaning liquid can be added to the melting material barrel 2, reducing the working frequency of the lifting component, reducing the loss of the lifting component, extending the service life, and having high practicability.

Through holes arranged in a linear array along the first direction Z are further provided on the stirring blades 202. During the rotation of the melting barrel 2 to drive the material to rotate, the stirring blades 202 play a role in stirring the material. At the same time, the material can also flow through the through holes on the stirring blades 202, further enhancing the stirring effect, thereby effectively accelerating the mixing of various raw materials and improving production efficiency.
