Problems solved by technology
[0004] The purpose of the present invention is to overcome the disadvantages of poor crushing effect and single function of the existing extrusion mechanism, and provide a low-temperature cracking extrusion mechanism. The required temperature avoids high-temperature treatment, realizes low-temperature plasticizing extrusion, energy saving and environmental protection, the active ingredients of the foaming material will not be destroyed, and the recycling rate of the foaming material is high. At the same time, the extrusion mechanism has high reliability. Extrusion plasticizing effect is good

Embodiment
[0032] combine Figure 1 to Figure 3 As shown, a low-temperature bursting extrusion mechanism of this embodiment includes a screw 2 and a screw barrel 1 sleeved outside the screw 2, a heating member 3 is arranged on the screw barrel 1, and the screw 2 includes a connecting section 21 for extruding The feed compression section 23 for pressing and pushing the material, the crushing section 24 for shearing and pulverizing the material, and the grinding section for grinding the material, the connecting section 21, the feeding compression section 23, the crushing section 24 and the grinding section The output direction is set in sequence, and the material moves in the gap between the screw 2 and the screw barrel 1 under the action of the screw 2 and is finally output after being ground by the grinding section. For waste foaming materials, since there is gas inside the foaming material, there will be bubbles inside the material, so when plasticizing it, it is necessary to squeeze th...

Abstract
The invention discloses a low-temperature foaming material breaking extruding mechanism, and belongs to the field of extruding devices. The low-temperature foaming material breaking extruding mechanism comprises a screw rod and a screw cylinder arranged outside the screw rod in a sleeving manner, a heating part is arranged on the screw cylinder, the screw rod comprises a connecting segment, a feeding compressing segment used for extruding and pushing a material, a breaking segment used for shearing and crushing the material and a grinding segment for grinding the material; the connecting segment, the feeding compressing segment, the breaking segment and the grinding segment are sequentially arranged in the extrusion direction, the material moves in a gap between the screw rod and the screwcylinder under the effect of the screw rod and is finally ground through the grinding segment to be output. According to the extruding mechanism, low-temperature plastifying extrusion can be achieved, the mechanism is energy-saving and environment-friendly, the recycling rate of the foaming material is high, the extruding mechanism is high in use reliability, and the extrusion plastifying effectis good.
Description
technical field [0001] The invention relates to a material extruding mechanism, more specifically, relates to a low-temperature bursting bubble extruding mechanism. Background technique [0002] Foaming materials such as rubber, plastic, and rubber-plastic community will produce a large amount of waste, and waste disposal has always been a problem. If these wastes are thrown away directly, it will not only cause a lot of waste, but also these wastes are difficult to degrade by themselves, which will cause great pollution , Therefore, these waste materials are usually processed and reused now. Since the foamed material will form a thermal insulation structure, it is difficult for the external temperature to penetrate into its interior. Therefore, when dealing with the waste of the foamed material, it is often necessary to first crush it through an extrusion mechanism composed of screws and other components, and then pass it through extrusion. However, the existing extrusion ...
