Description

[0002] EVA is a copolymer of ethylene and acetic acid. Its applications are quite extensive, and its annual market consumption in my country is constantly increasing, especially in the footwear industry, where it is used in the soles and linings of mid-to-high-end hiking shoes, mountaineering boots, slippers, and sandals. It also has wide applications in the new energy field, such as photovoltaic materials and solar cell adhesives. Footwear materials are the most important application area for EVA resin in my country. The vinyl acetate content in EVA resin used in footwear materials is generally between 15% and 22%. Because EVA resin blends and foams possess properties such as softness, good elasticity, and chemical resistance, they are widely used in the soles and linings of mid-to-high-end hiking shoes, mountaineering boots, slippers, and sandals. In addition, this material is also used in sound insulation panels, gymnastics mats, and sealing materials.

[0003] In the production and processing of EVA foam particles, it is necessary to mix the granulated particles with other raw materials. The granulated particles have a high temperature and are prone to sticking together, resulting in uneven mixing and adversely affecting subsequent production and processing. To address this, this application proposes a mixing machine for EVA processing, providing a new technical solution to solve the aforementioned technical problems. Summary of the Invention

[0004] Based on this, it is necessary to provide a mixing machine for EVA processing to address the above-mentioned technical problems. Through the structural design of the mixing mechanism, the device can mix the materials for EVA processing, and by filling the cooling chamber with cooling liquid, the materials for EVA processing can be cooled, thereby reducing the mixing temperature and reducing the amount of material sticking due to excessive temperature.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A mixing machine for EVA processing, which is used for mixing materials in EVA processing.

[0013] In a preferred embodiment of the EVA processing mixer provided by this utility model, the mixing rack is provided with a recess near the material compartment door.

[0014] In a preferred embodiment of the EVA processing mixer provided by this utility model, the support mechanism includes a support frame, the two sides of which are rotatably connected to the outer side of the mixing mechanism, the two sides of which are set at a 90-degree angle to the material compartment door, and an adjusting motor is fixedly connected to one side of the support frame for driving the mixing mechanism to rotate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background section, the granulated particles have a high temperature and are prone to sticking together, resulting in uneven mixing and adversely affecting subsequent production and processing.

[0030] To solve this technical problem, this utility model provides a mixing machine for EVA processing, which is applied to mixing materials in EVA processing.

[0031] Specifically, please refer to Figures 1-3. The mixing machine for EVA processing includes:

[0032] The mixing mechanism 1 includes a spherical mixing container 3, a spherical cooling container 4 fixed to the outside of the spherical mixing container 3, a cooling chamber between the spherical mixing container 3 and the spherical cooling container 4, the cooling chamber being filled with cooling liquid, a mixing rack 9 inside the spherical mixing container 3, a drive motor 10 for driving the mixing rack 9 to rotate at one end of the spherical cooling container 4, and a material compartment door 8 at the other end of the spherical cooling container 4.

[0033] Support mechanism 2 is located at the lower part of mixing mechanism 1 and is used to support mixing mechanism 1.

[0034] The EVA processing mixer provided by this utility model, through the structural design of the mixing mechanism 1, enables the device to mix the materials for EVA processing, and by filling the cooling chamber with cooling liquid, the materials for EVA processing can be cooled, thereby reducing the mixing temperature and reducing the amount of material sticking due to excessive temperature.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1: Please refer to Figures 1-3. A mixing machine for EVA processing includes:

[0037] The mixing mechanism 1 includes a spherical mixing container 3, a spherical cooling container 4 fixed to the outside of the spherical mixing container 3, a cooling chamber between the spherical mixing container 3 and the spherical cooling container 4, the cooling chamber being filled with cooling liquid, a mixing frame 9 inside the spherical mixing container 3, a drive motor 10 for driving the mixing frame 9 to rotate at one end of the spherical cooling container 4, and a material door 8 at the other end of the spherical cooling container 4. It can be seen that the mixture can be fed into the spherical mixing container 3 through the material door 8, and the mixing frame 9 can be rotated inside the spherical mixing container 3 by starting the drive motor 10, thereby achieving the mixing effect. Furthermore, the cooling liquid filling the cooling chamber between the spherical mixing container 3 and the spherical cooling container 4 can reduce the temperature of the mixture, thus reducing the amount of material sticking due to excessively high temperature.

[0038] In order to replace the cooling liquid in the cooling chamber, a first liquid replacement port 6 is provided on the outer side of the spherical cooling container 4 near one end, and the first liquid replacement port 6 is connected to the cooling chamber; a second liquid replacement port 7 is provided on the outer side of the spherical cooling container 4 near the other end, and the second liquid replacement port 7 is connected to the cooling chamber.

[0039] Furthermore, a guide plate 5 is fixedly connected inside the cooling chamber. The guide plate 5 is spiral-shaped. It can be seen that when liquid is introduced through the guide plate 5 in conjunction with the first liquid exchange port 6 and the second liquid exchange port 7, the liquid will flow around the outside of the spherical mixing container 3 along the guide plate 5 due to the obstruction and guidance of the guide plate 5. Finally, the liquid will be discharged through the second liquid exchange port 7 or the first liquid exchange port 6 at the other end. Through continuous liquid exchange, the temperature of the liquid can be ensured, thereby continuously cooling the mixture in the spherical mixing container 3.

[0040] Support mechanism 2 is located at the lower part of mixing mechanism 1 and is used to support mixing mechanism 1.

[0041] Example 2: Further optimization of the EVA processing mixer provided in Example 1. Specifically, as shown in Figure 6, the support mechanism 2 includes a support frame 14. The two sides of the support frame 14 are rotatably connected to the outer side of the mixing mechanism 1. The two sides of the support frame 14 are set at a 90-degree angle to the material compartment door 8. An adjustment motor 15 is fixedly connected to one side of the support frame 14 to drive the mixing mechanism 1 to rotate.

[0042] Through the above structural design, the support frame 14 is rotatably connected to the mixing mechanism 1, allowing the mixing mechanism 1 to rotate when the regulating motor 15 is started. This rotation of the mixing mechanism 1 during mixing ensures that the materials in the spherical mixing container 3 are mixed more quickly and evenly. Furthermore, the rotation of the mixing mechanism 1 facilitates both the addition and removal of materials.

[0043] Example 3: The EVA processing mixer provided in Example 1 is further optimized. Specifically, as shown in Figures 4-5, the mixing frame 9 includes a rotating shaft 11, one end of which is fixedly connected to the output end of the drive motor 10, and a stirring frame 12 is fixedly connected to the outside of the rotating shaft 11. In order to avoid affecting the filling and discharge of the mixture, a recess 13 is provided on the stirring frame 12 near the material compartment door 8.

[0044] Through the above structural design, the rotation of the rotating shaft 11 can drive the stirring rack 12 to rotate along the inner wall of the spherical mixing container 3, thereby achieving the mixing effect of materials. Furthermore, the recess 13 provided near the material compartment door 8 of the stirring rack 12 reduces the obstruction of the stirring rack 12 to the materials during the mixing or discharging process.
