Embodiment Construction

[0017] The preferred embodiments of the present invention will now be described in conjunction with the accompanying drawings.

[0018] refer to figure 1 , a high-strength, high-modulus ultra-high molecular weight polyethylene fiber hot air drafting box of the present invention includes a silk path 1 and an air path 21 communicating with the thread path 1, an electric heater 211 is arranged in the air path 21, and the two ends of the thread path 1 A wire inlet and a wire outlet are provided, and each panel of the wire path 1 is provided with an electric heating film 3 connected with an electric heater 211 . The electric heating film 3 is controlled by the electric heater 211 through the control circuit 213 . Utilizing the characteristics of fast heating speed of the electric heating film, when the temperature drops in the thread path, the control circuit controls the electric heater to automatically start the electric heating film to generate heat, and heats up rapidly to com...

Abstract

The invention relates to a hot air drawing box for high-strength high-modulus superhigh molecular weight polyethylene fibers, which comprises a filament channel and an air channel communicated with the filament channel. An electric heater and a fan are arranged in the air channel; an electric heating membrane for compensating heat is additionally arranged in the filament channel; the electric heater and the electric heating membrane heat circulating air together, so that the temperature in the filament channel keeps constant and uniform; the fan blades of the fan are horizontal long straight square blades, and are arranged into a cylinder along the periphery by forming a certain angle; the electric heater is provided with a control circuit used for controlling the electric heating membrane; and the electric heating membrane is arranged on a panel of the filament channel. The hot air drawing box can reduce the probability of occurrence of broken filaments and end breakage in the process of drawing the fibers so as to improve product quality.

Description

technical field [0001] The invention relates to a fiber drawing heating device, in particular to a high-strength, high-modulus, ultra-high molecular weight and high molecular weight polyethylene fiber hot air drawing box. Background technique [0002] The hot air drawing box is one of the key equipment in the production process of high strength, high modulus and high molecular weight polyethylene fiber. The final performance of high strength, high modulus and high molecular weight polyethylene fiber is realized by hot drafting. It draws while heating. The length of the drafting box is generally between 2.5 meters and 6 meters. Most of them adopt the self-circulation method of the box, and the hot air enters one end and exits the other end. The existing hot air drawing box is provided with a thread path, one end of which is respectively provided with a tow inlet and an air inlet, and the other end is provided with a tow outlet and an air outlet. On one side or both sides of t...
