Example Embodiment

[0020] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0021] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a prestressed chilled cast iron roll includes a prestressed head anchor bundle assembly and a chilled cast iron roll 3. The chilled cast iron roll 3 is provided with a slot 9 at one end and an inner groove 8 at the other end. The prestressed head anchor bundle assembly includes a prestressed high-strength steel wire bundle 4, a fixed end head anchor plate 2, a protective cover 1, a tension end head anchor 10, and a protective cover 7. The pre-stressed high-strength steel wire bundle 4 passes through the inner hole of the chilled cast iron roll 3 and is anchored on the fixed end upsetting anchor plate 2 at both ends and the tension end upsetting anchor 10. The fixed-end upsetting anchor plate 2 is anchored in the inner groove 8 of the chilled cast iron roll 3, and the end of the inner groove...

Abstract

The invention relates to the field of rubber and plastic machinery and concretely relates to a pre-stress chilled cast iron roll for rubber and plastic plastication and mixing. The pre-stress chilled cast iron roll comprises a pre-stress upset head anchorage cable assembly and a chilled cast iron roll. Pre-stress is applied to the chilled cast iron roll and thus the chilled cast iron roll structure does not bear radial load produced by rubber and plastic plastication and mixing so that roll breaking risk is reduced or eliminated, more rare metals for improving the chilled cast iron roll structure are avoided and a manufacturing cost is reduced. A common model casting method is adopted so that manufacturing difficulty and cost are reduced. The pre-stress is applied to the chilled cast iron roll and can be adjusted according to types, formulas and technology of rubber and plastic plastication so that bending moments on the chilled cast iron roll are balanced and roll surface parallelism is guaranteed and thus quality of the produced rubber and plastic sheets is guaranteed.

Description

technical field [0001] The invention relates to the field of rubber and plastic machinery, in particular to a prestressed chilled cast iron roll used for plasticizing and mixing rubber and plastic. Background technique [0002] At present, rubber and plastic products are closely related to people's production and life, and play a huge role in various industrial fields. The important equipment used in the rubber and plastic smelting and mixing process is the open mill. A pair of rolls of the open mill are usually made of chilled cast iron. The chilled cast iron roll has the advantages of wear resistance and no deformation, but due to the material, casting Due to limitations in technology, roll breakage will occur and the service life will be affected. At the same time, due to the different degree of wear of the roller surface, the thickness of the plasticized rubber and plastic sheet is not uniform. How to increase the service life of chilled cast iron rolls, reduce the cos...
