Description

Technical Field

[0001] The utility model relates to the technical field of calenders, in particular to a combined calender for rubber production. Background Art

[0002] A calender is a machine composed of two or more rollers arranged in a certain form, which presses and stretches rubber or plastic into a film of a certain thickness and surface shape, and can also coat fiber curtain canvas or steel cord with rubber. The calender can be divided into two-roller, three-roller, four-roller and five-roller calenders according to the number of rollers. The existing calenders for rubber production are prone to rubber rebound after production, and the existing calenders for rubber production can only calender rubber sheets of a specific thickness, cannot be adjusted according to demand, and are not flexible to use.

[0003] And in the application document with publication number CN209999574U, a combined calender for rubber production is mentioned. The calender is powered on, and the rubber sheet to be calendered passes through the slotted heating box and is sent between the first rolling roller and the second rolling roller. The cylinder extends or contracts, driving the connecting seat to move downward or upward, thereby causing the second rolling roller to move upward or downward, and adjusting the spacing between the second rolling roller and the first rolling roller to accommodate rubber sheets of different thicknesses. The motor drives the second transmission wheel to rotate, and the second transmission wheel drives the first transmission wheel to rotate through the transmission belt, thereby causing the first rolling roller to rotate. Under the interaction between the first rolling roller and the second rolling roller, the rubber sheet is calendered. The rubber sheet is rolled and fed forward. During the feeding process, the heating tubes at the top and bottom of the heating box generate heat to heat the top and bottom of the rubber sheet passing through the heating box. The rubber sheet will soften after being heated, and then it is rolled by the first rolling roller and the second rolling roller. The rolled rubber sheet is not easy to rebound, so the rubber sheet is calendered. The calendered rubber sheet moves on the material plate. Under the action of the rotating roller, the rubber sheet is not easy to pile up. After calendering, the power supply is disconnected. However, there are still certain defects that need to be optimized. The specific defects are as follows: the rubber sheets are pressed out with different widths, and there is no limiting device at the outlet of the finished product. The finished product is easy to fall along the edge of the rotating roller, affecting the effect.

[0004] Therefore, it is particularly important to design a combined rubber production calender to change the above-mentioned technical defects and improve overall practicality. Utility Model Content
