MC (Methyl Cellulose) colorful co-extrusion material drying device

Abstract

The invention discloses an MC (Methyl Cellulose) colorful co-extrusion material drying device which comprises a base, a hot air blower, a ventilation tube as well as a guide cover, a diversion valve and a drying tank, wherein the hot air blower is connected with the base; the ventilation tube is communicated with an outlet of the hot air blower; the guide cover is communicated with the end part ofthe ventilation tube; the diversion valve is communicated with the side wall of the ventilation tube; a connecting rod is arranged on the side wall of the drying tank; a hoop is arranged at the end part of the connecting rod; the hoop is fixedly connected with the ventilation tube; a first water absorbing roller, a second water absorbing roller and a third water absorbing roller are rotationallyarranged on the drying tank; two support rods are arranged on the inner wall of the drying tank; a spiral drying air cylinder is arranged between the two support rods; an air inlet is formed in one end of the spiral drying air cylinder; and a spiral air channel is formed in the inner wall of the spiral drying air cylinder. By adopting the device, drying of plastic strips at a tension state is achieved, insufficient drying caused by mutual connection is avoided, meanwhile coactive hot air drying of vertical air blowing and transverse spiral air blowing is achieved, and the drying effect and thedrying efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of plastic strip processing equipment, in particular, the invention relates to a drying device for MC color co-extruded materials. Background technique [0002] In the production process of plastics, thermoplastic elastomers or plastics, the plastics, thermoplastic elastomers or plastics are first extruded into strip-shaped plastic strips through an extruder, and then the plastic strips are cooled by a cooling water tank, and then the plastic strips are dried by a drying device. Blow dry on moisture. [0003] However, the plastic strip drying devices in the prior art all utilize blowing air at normal temperature to dry the plastic strips, and the plastic strip drying devices of the prior art cannot quickly dry the plastic strips, and the plastic strips pass through the drying device. In the process, it passes in a straight line and is not in a tensioned state, the residence time is short, and the multiple p...

Problems solved by technology

[0005] In the technical solution of this patent, the plastic strips are connected together, not in a tight state, or it will cause the places in contact with each other to be difficult to be dried, resulting in poor drying effect, and only the drying operation in the vertical direction, the wind blowing stroke is short , the drying effect is not very good
