Abstract

The invention discloses a thread detection system for an underwater stay horizontal type granulator. The thread detection system comprises a thread detection device which is arranged above a startinghead in a non-contact mode and is relatively parallel to the starting head. The thread detection device comprises an upper bracket, a lower bracket, a right installation plate, a left installation plate and infrared thermometers; infrared probes of the infrared thermometers face towards a discharging outlet of a casting strip head; a fan-shaped rail for conveniently adjusting the angle of the infrared probe is formed between the right installation plate and the left installation plate, and the angle of the fan-shaped rail is 0-90 degrees; and the infrared probes are uniformly distributed on the fan-shaped rail. The thread detection system achieves non-contact thread detection and is high in detection precision, good in control effect, high in instantaneity and capable of quickly and accurately reflecting the thread state and judging whether the melt stacking phenomenon occurs or not, accordingly, the chain reaction halting is efficiently controlled in real time, the granulator is protected from being damaged or little damaged, intelligentization and automation are achieved, the space is saved, installation is convenient, the reliability is high, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical fields of petrochemical industry and plastic granulation, and more specifically, relates to a wire strand detection system and a detection method for an underwater sliver horizontal pelletizer. Background technique [0002] As we all know, the whole working process of the underwater sliver pelletizer is like this, when the high-temperature polyester melt with a certain pressure extrudes the strip from the casting head, the cast strip is first submerged in the pelletizer by gravity to start The overflow water on the plate is cooled, and then flows through two streams of the guide plate with grooves: one is used to cool the freshly cut particles; the other is used to transport the sliced ​​particles out of the pelletizer, so that through the cutting The continuous operation of the machine achieves the purpose of continuous pelletizing. [0003] The underwater granulator is divided into vertical and horizontal accor...
