Sealed water-ring thermal cutting machine set

Abstract

The invention discloses a sealed water-ring thermal cutting machine set which comprises a frame, a thermal cutting machine arranged on the frame, a flow guide slot and a centrifugal dehydrator, wherein, the thermal cutting machine comprises a water-ring shield body, a discharge die arranged on the front end of the water-ring shield body, a motor arranged on the tail end of the water-ring shield body, and a cutting knife group and a power unit arranged in the water-ring shield body; the cutting knife group is connected with the motor through the power unit, the water-ring shield body takes a cylindrical shape, and the side wall of the water-ring shield body is equipped with a water outlet communicated with the flow guide slot; the discharge port of the flow guide slot is connected with the water collecting port of the centrifugal dehydrator; and the bottom of the centrifugal dehydrator is equipped with a water tank for collecting water. In the invention, by setting the water-ring shield body, the cooling speed of elastic soft materials is accelerated so as to facilitate pelletizing of a pelletizer; and meanwhile by adopting the flow guide slot and the centrifugal dehydrator, the airing and dewatering effects of the pelletized materials are enhanced, thus ensuring pelletizing effect and pelletizing quality. The sealed water-ring thermal cutting machine set has the advantages of high tightness of the water-ring shield body, good material airing effect, rational structure and convenient use.

Description

technical field [0001] The invention relates to a water ring hot cutting device in the field of plastic processing, in particular to a sealed water ring hot cutting unit. Background technique [0002] At present, the processing of plastic products in my country is to a large extent plasticized plastic powder for molding processing. The extruder is the most widely used equipment in polymer processing. After the polymer is mixed with various additives, it is fed into the extruder to be melted and further mixed evenly; through a multi-hole die, multiple strips are formed, and then cut into pellets. Cutting can be divided into hot-cut pelletizing and cold-cut pelletizing. Among them, hot-cut pelletizing is to cut off the strip with a rotary knife while cooling it with air or water after it leaves the die. [0003] However, when the existing hot granulation mechanism is in use, it is difficult to cool, especially when the output increases, and the granulation bubbles are large,...

Problems solved by technology

[0003] However, when the existing hot granulation mechanism is used, it is difficult to cool, especially when the output increases, and the granulation bubbles are large, especially the cooling of the elastic soft material is slow, and the granulation quality is difficult to guarantee.

In recent years, domestic research has been carried out on water-cooled hot-cut granulation, but due to poor sealing, serious water leakage, and cooling water sprayed on the formwork in the form of mist, the temperature of the formwork has dropped sharply, which is difficult to control and reduces the quality of granulation. unstable
