Thermoplastic polyurethane elastomer drying and conveying integrated device

Abstract

The invention discloses a thermoplastic polyurethane elastomer drying and conveying integrated device which comprises a bracket and a spiral conveyor, wherein the vertical surface of the bracket is provided with a control panel; the interior of the control panel is fixedly connected with a circuit mainboard; the middle of the circuit mainboard is provided with a controller; one side of the horizontal surface of the bracket is fixedly connected with a motor base, and the motor base is in bolt connection with a motor; one end of the motor is connected with a revolution speed transducer. The thermoplastic polyurethane elastomer drying and conveying integrated device is reasonable in design and is quite applicable to drying and conveying thermoplastic polyurethane elastomers; by virtue of arranging a first blower and a heat conducting net, and in combination with a heater, materials from a discharge hopper can be further effectively dried; by virtue of arranging a second blower, air flow in the spiral conveyor can be increased so as to dry products; by virtue of arranging helical blades and a rotating shaft, and in combination with resistance wires, the product drying area can be increased, the drying degree can be effectively improved, and the thermoplastic polyurethane elastomer drying and conveying integrated deiced is suitable for extensive promotion.

Description

technical field [0001] The invention relates to the technical field of thermoplastic polyurethane elastomers, in particular to an integrated device for drying and transporting thermoplastic polyurethane elastomers. Background technique [0002] Thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, referred to as TPU, is a (AB) n-type block linear polymer, A is a high molecular weight polyester or polyether, and B is a diatom containing 2 to 12 straight-chain carbon atoms. Alcohol, the chemical structure between AB chain segments is diisocyanate. Thermoplastic polyurethane rubber is cross-linked by intermolecular hydrogen bonds or lightly cross-linked between macromolecular chains. As the temperature increases or decreases, these two cross-linked structures are reversible. In the molten state or solution state, the intermolecular force weakens, and after cooling or solvent volatilization, strong intermolecular force connects together, restori...

Problems solved by technology

Typical TPU such as spandex, thermoplastic polyurethane elastomer, has become one of the important thermoplastic elastomer materials due to its excellent performance and wide application. In the production and manufacture of thermoplastic polyurethane elastomer, the extruded thermoplastic polyurethane elastomer is usually The body is dried openly, and the product is conveyed by belt transmission, which is easy to pollute the thermoplastic polyurethane elastomer, and the drying is insufficient, which reduces the product quality
