Description

Technical Field

[0001] The utility model relates to the technical field of calenders, in particular to a sliding connection structure and a four-roller calender. Background Art

[0002] The four-roll calender is a commonly used processing equipment. Its working parts are composed of four rollers. In the rubber industry, it is mainly used for fabric gluing, steel cord gluing, rubber sheeting, rubber blank profiling, isolation film pasting and multi-layer film lamination.

[0003] The Chinese Patent Database has disclosed a patent entitled "An Efficient Calender", with the authorization announcement number CN116690876B, in which the first roller is slidably connected to the side plate through the first track block, and the third roller and the fourth roller are connected to the side plate through the second track block. In the process of adjusting the roller spacing, the first track block will directly move along the first track groove, and the second track block will move along the second track groove. During long-term use, the first track groove and the second track groove will be worn. At the same time, since the calender works in the way that the roller squeezes the material to deform the material, the reaction force of the material on the roller is also relatively large, and the reaction force will eventually be transmitted to the side plate, which will further cause the side plate to wear and deform, thereby causing the positioning position of the first track block and the second track block to shift, affecting the positioning accuracy between the rollers, and ultimately having an adverse effect on the dimensional accuracy of the material forming.
