Description

Technical Field

[0001] The utility model relates to the technical field of cast film production equipment, and more specifically to a PE cast film cooling device. Background Art

[0002] Cast film is a non-stretched, non-directional flat extruded film produced by quenching the melt. Cast film has excellent heat sealing properties and good transparency. It is one of the main packaging composite substrates. The cast film needs to be cooled after forming. The cooled cast film is solidified and then rolled up.

[0003] The existing announcement number is CN214419367U, and its name is a PE cast film cooling device, which includes a vertical rod, a sliding sleeve, a cooling box, a ventilation hose and an air pump. The sliding sleeve is arranged on the vertical rod and can slide along the vertical rod, and the sliding sleeve can rotate relative to the vertical rod. The cooling box is a box structure with openings at both ends. The cooling box is a double-wall sandwich structure. A plurality of ventilation holes connected to the cavity of the sandwich are opened on the inner wall of the cooling box. One side of the cooling box is rotatably connected to the sliding sleeve. The air pump is arranged on one side of the vertical rod. One end of the ventilation hose is connected to the output end of the air pump, and the other end is fixedly passed through the outer wall of the cooling box, and the other end is connected to the cavity of the sandwich. According to the traction direction and traction angle of the film in the production process, the operator first rotates the sliding sleeve, so that the sliding sleeve drives the cooling box to rotate until the connecting line of the openings at both ends of the cooling box is roughly in the direction of traction of the film.

[0004] However, during the processing of the above-mentioned cast film, air is introduced into a cooling box. When the cast film passes through the cooling box, it contacts the introduced air and is cooled. However, the surface of the newly formed cast film is relatively soft and has strong plasticity. The guided air blows on the surface of the cast film. The strong airflow blows on the surface of the cast film, causing deformation lines to appear on the surface of the cast film, resulting in poor production effect of the cast film.
