Description

EVA sheet kneading device for feeding by driving sliding plate through air cylinder Technical Field The utility model relates to the field of EVA sheet kneading internal mixers, in particular to an EVA sheet kneading device with a cylinder driving sliding plate for feeding. Background EVA (ethylene vinyl acetate copolymer) is used in various fields because it has excellent plasticity, elasticity and good foaming properties. In general, when EVA is used for preparing a corresponding material, EVA is required to be compounded with other raw materials (such as a filler, a cross-linking agent, an antioxidant, etc.), fully mixed and banburying to obtain a composite material, and processing and molding the composite material to obtain a corresponding product. Among them, the EVA sheet is an important EVA-derived product. When the EVA sheet is processed, firstly, EVA particles and other materials are mixed by a kneading internal mixer and then are subjected to compression molding, powdery materials (such as carbon black and the like) are usually added into raw materials mixed and compounded with the EVA particles, and as the temperature in the internal mixing chamber is usually 100-200 ℃, the powder materials are easy to adhere on the inner wall of the internal mixer and cannot completely enter the internal mixing chamber when the powder materials are fed into the internal mixing chamber, so that a certain degree of material loss is caused, the inner wall of the internal mixer is difficult to clean, and the internal mixing effect of materials adhered on the inner wall of the internal mixer can be influenced. To solve the above problem, the Chinese patent with publication number of CN212241669U discloses an EVA sheet kneading internal mixer convenient for powder feeding, wherein the upper end of a feeding pipeline 3 penetrates through the top wall 211 and is connected with a powder storage hopper 5. Thus, when powder feeding is performed, powder is firstly fed into the powder storage hopper 5, enters the feeding pipeline 3 through the first feeding port 12, and slides into the banburying chamber 2. A cover 51 is further provided at the upper end of the powder storage hopper 5. Although the device can regularly detach the feeding pipeline 3 from the internal mixer to remove materials adhered to the inner wall of the internal mixer, when the EVA sheet kneading device (internal mixer) is used for feeding materials, the high-temperature cavity or splashed materials in the sheet kneading device exist in the process of manually uncovering and feeding materials in actual use, and the risks of scalding skin and sucking dust exist.
