Description

Technical Field

[0001] This utility model belongs to the field of calendering technology, specifically relating to an improved structure of an aviation tire cord calendering machine. Background Technology

[0002] A calender consists of two or more rollers arranged according to the heating method. It can be divided into cold calenders and hot calenders. Cold calenders are suitable for materials that do not require heating, such as graphite films, graphite sheets, microwave absorbing materials, shielding materials, magnetic materials, and non-ferrous metals. Hot calenders are further divided into water heating, electric heating, oil heating, and electromagnetic heating. All three methods involve pressing and stretching materials such as rubber, silicone rubber, silicone rubber, phase change materials, PTFE, or plastics into sheets of a certain thickness and surface shape at a specific temperature. They can also be used to coat fiber optic fabrics or steel wire fabrics with adhesive. Calenders are classified according to the number of rollers (two-roll, three-roll, four-roll, and five-roll calenders) and the arrangement of the rollers ("L", "T", "F", "Z", and "S" types).

[0003] Aviation tire cord fabric needs to have extremely high strength, uniformity and density. Its calendering quality directly affects the safety performance of the tire. Traditional calendering machines often use the movement of the entire frame or simple screw adjustment when adjusting the distance between the two rollers, which has the problems of low adjustment accuracy and easy to cause fluctuations in the tension of the cord fabric.

Two sets of clamping components are symmetrically installed on the front side of assembly plate 9 to clamp the two ends of the curtain. When the calendering roller 19 is moved to adjust the roller distance, the controller synchronously commands electric guide rail 6 to drive the clamping components to move, so that the curtain path length matches the roller distance and maintains constant tension. Assembly block 10 is fixed on assembly plate 9. Movable rod 14 passes vertically through assembly block 10. Force plate 11 and clamping plate 15 are respectively fixed to the top and bottom of movable rod 14. Spring 13 is sleeved on movable rod 14, with the upper end pressing against assembly block 10 and the lower end pressing against clamping plate 15. Pressing down handle 12, force plate 11 drives movable rod 14 to move upward, clamping plate 15 is disengaged from curtain. After the curtain is inserted, release handle 12, and spring 13 pushes clamping plate 15 to press the curtain tightly.
