Description

Technical Field

[0001] The utility model relates to the technical field of material cooling and shaping, in particular to a low-viscosity melt guiding device. Background Art

[0002] During the material synthesis stage, due to the special requirements for material viscosity, the polymer is discharged at a relatively low viscosity. Due to the low melt viscosity and low melt strength, and the excessive height between the melt discharge die and the cooling water level, the melt beam becomes thinner rapidly after the melt is discharged, resulting in a low 100-grain weight of the slices after pelletizing, which has an adverse effect on the operation of some physical property testing instruments and small spinning equipment.

[0003] For example, when the filtration equipment is conducting a filtration test on slices, if the 100-grain weight of the slices is too small, it will easily cause problems such as uneven feeding of the slices and bridging, which will further cause problems such as high-speed idling of the screw equipment, causing troubles to the experimental accuracy and equipment maintenance. At the same time, the small 100-grain weight of the slices may cause poor operation of small spinning equipment. Utility Model Content

[0031] The top of the cooling water storage tank 3 is fixedly connected with a cooling water tank overflow port 8 , and the top of the cooling water tank overflow port 8 is fixedly connected with the bottom of the cooling water overflow pipe 4 .

The cooling water overflowing from the cooling water overflow pipe 4 cools and shapes the melt bundle, and the tendency of the melt bundle to become thinner is further weakened.

[0044] Optional, see Figure 5 The cooling water is circulated from one end of the cooling water tank 12 through the circulation motor 10 and enters the cooling water storage tank 3 through the cooling water tank inlet 9. After the cooling water is full, it enters the cooling water overflow pipe 4 through the overflow port 8, and finally flows into the guide groove 1 to cool and shape the melt.
