Description

Technical Field

[0001] This utility model relates to the technical field of casting extrusion devices, specifically a TPU film casting extrusion device. Background Technology

[0002] A TPU film casting extrusion unit is a specialized piece of equipment used to produce thermoplastic polyurethane (TPU) films. Its working principle involves adding TPU granules into the hopper of an extruder. The screw rotation causes the TPU granules to gradually move forward under conveying, compression, and shearing action, heating them to a molten state. The molten TPU material is then extruded through a slit-type die under extruder pressure to form a continuous thin film melt. The extruded film melt then comes into contact with a cooling system, where it rapidly cools and solidifies under the action of the cooling medium, forming a TPU film with a certain thickness and width. Finally, it is pulled by a traction device and wound into a roll by a winding device.

[0003] For example, a TPU film casting and extrusion device with publication number CN218315101U mainly utilizes a heating box, heat-conducting plate, heater, stirring mechanism, and air-cooling mechanism to achieve the TPU film casting and extrusion process. The heating box heats the material via the heat-conducting plate, and then a second motor drives the rotating shaft to rotate. The raw material is stirred by a connecting rod, and simultaneously heated by an electric heating rod, resulting in a more uniform melting of the material. At the same time, the air-cooling mechanism cools the film material, preventing deformation.

[0004] Based on the search of patent numbers, and combined with the shortcomings of existing technologies, the following findings were made;

[0005] Existing casting extrusion equipment uses air cooling for heat dissipation, which removes heat through airflow. However, its heat dissipation efficiency is relatively low, and it cannot dissipate heat in a timely and effective manner, resulting in insufficient film cooling and reducing the performance of the casting extrusion equipment.

Simultaneously, the bearing support ring 45, in conjunction with the connecting ring 44, can provide movable support to the other side of the cooling roller 3, ensuring stable operation and preventing any disruption to its normal use. During operation, the limiting plate 52 can limit the internal movement of the cooling tank 51, allowing water to enter one side of the limiting plate 52 through the inlet of the separating ring 53, then flow to the other side of the limiting plate 52, through the outlet of the separating ring 53, and into the water outlet pipe 55, ultimately entering the cooling tank 57. Simultaneously, the water pump 56 can be started, drawing water from the cooling tank 57 through its suction end and then delivering it to the inlet pipe 54 through its output end. After passing through the inlet pipe 54, the water can enter the cooling tank 51 through the separating ring 53, circulating and cooling the cooling roller 3, thus achieving a circulating cooling effect and enhancing the performance of the casting extrusion device.

This solves the problem that existing casting extrusion devices use air cooling for heat dissipation, which carries away heat through airflow. However, the heat dissipation efficiency is relatively low, and the heat cannot be dissipated in a timely and effective manner, resulting in insufficient film cooling and reduced performance of the casting extrusion device.
