Abstract

The invention discloses mixing equipment for a flame-retardant thermoplastic polyurethane elastomer. The mixing equipment comprises an equipment main body, the bottom end of the equipment main body is fixedly connected with a top plate, the two sides of the bottom end of the top plate are fixedly connected with supporting rods, the bottom ends of the supporting rods are fixedly connected with a bottom plate, and a uniform discharging mechanism is arranged between the top plate and the bottom plate. A material guiding mechanism is arranged below a water inlet and comprises a third driving motor arranged on the outer wall of the equipment main body, the third driving motor is transversely arranged, a rotating shaft is arranged at the output end of the third driving motor, and the third driving motor, a cam, a spring and a discharging plate are connected in a matched mode. Materials crushed by a crushing mechanism and materials entering from the water inlet can fall on the surface of the discharging plate and fall near a mixing and crushing mechanism through the discharging plate, the material guiding effect is achieved, and the materials can be prevented from being concentrated at the corner of the equipment main body.

Description

technical field [0001] The invention relates to the technical field of flame-retardant material processing, in particular to a mixing device for flame-retardant thermoplastic polyurethane elastomers. Background technique [0002] At present, thermoplastic polyurethane elastomers are widely used in various fields due to their material characteristics, such as shoe materials, plates, cables, films, etc., thermoplastic polyurethane elastomers need to be mixed with other materials evenly during processing to ensure that the materials It has a better flame retardant effect, but there are still some problems in the existing processing equipment of thermoplastic polyurethane elastomers. The mixing and stirring structure is too simple, resulting in insufficient mixing effect between materials. [0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: [0004] (1) The traditional...
