AI Technical Summary
The existing roller structure of casting machine has problems such as insufficient friction leading to slippage, uneven film stretching and local stress concentration in film production, and insufficient overall rigidity leading to flexural deformation, which affects film quality and mechanical properties.
A casting machine roller structure is designed, which uses sandblasting to form irregular pit units and a continuous network support structure on the roller surface, combined with annular bosses to enhance rigidity, and eliminates sharp edges by smooth transition edges to ensure stable contact between the film and the roller.
This achieves uniform distribution of film tension, avoids wrinkles and breaks, and improves the yield rate and mechanical property consistency of film production.

Abstract
Claims
1. A cast film roll structure, characterized by, It includes a roller base, and the middle area of the outer circumferential surface of the roller base is formed with a rough working surface by sandblasting process; Annular bosses are provided at both ends of the roller base. The annular bosses are coaxially distributed with the rough working surface, and the outer diameter of the annular bosses is greater than or equal to the outer diameter of the rough working surface. The rough working surface has several irregularly shaped pit units, and adjacent pit units naturally form connected protrusions. These protrusions are interconnected on the roller surface, forming a continuously distributed network support structure. There is a difference between the depth of the recessed unit and the height of the protruding connecting part.
2. A cast film roll structure according to claim 1, wherein The cross-sectional shape of the protruding connection is an irregular polygon, and its edge smoothly transitions with the outline of the recessed unit.
3. A cast film roll structure as claimed in claim 1, wherein, A smooth transition structure is formed between the inner end face of the annular boss and the edge of the rough working surface; The surface roughness of the smooth transition structure is lower than that of the rough working surface and higher than that of the outer circumferential surface of the annular boss.
4. A cast film roll structure as claimed in claim 1, wherein, The rough working surface covers the middle area along the axial direction of the drum base; The annular bosses are located at both ends of the roller base and have equal axial widths. The axial coverage length of the rough working surface is greater than the sum of the axial widths of the annular boss.
5. A cast film roll structure as claimed in claim 1, wherein, The pit units on the rough working surface are continuously distributed along both the circumferential and axial directions of the roller base.
6. A casting machine characterized by Includes a casting machine roller structure as described in any one of claims 1-5.
