A rubber and plastic molding calender

Abstract

The invention relates to the field of calenders, in particular to a rubber and plastic forming calender, which includes a calendering sleeve, a fixed block, a cleaning structure, a connection structure, gears, a transmission structure and a heat exchange structure; it is used for pressing plastic and rubber materials The inside of the rolling sleeve with smooth surface of cylindrical structure is provided with a heat exchange structure for exchanging heat with the rolling sleeve; both ends of the rolling sleeve are provided with a transmission structure for transmission; the transmission structure is connected with a pipe for connecting oil bath heating equipment The connecting structure; the sliding connection between the calendering sleeve and the cleaning structure. The connection structure of the present invention cooperates with the transmission structure and the use of the internal heat exchange structure of the calendering sleeve at one end of the transmission structure, which facilitates the control of the temperature of the calendering sleeve through oil bath heat exchange or water bath heat exchange, avoiding the exchange between the calendering sleeve and air. The heating is too fast, thereby greatly improving the molding and pressing quality of rubber and plastic; the sliding connection between the calendering sleeve of the cylindrical structure and the cleaning structure is convenient for cleaning the waste debris on the calendering sleeve.

Description

technical field [0001] The invention relates to the field of calenders, in particular to a rubber and plastic molding calender. Background technique [0002] The calender is a machine that presses and stretches rubber or plastic into a film of a certain thickness and surface shape at a certain temperature, and can glue the fiber cord canvas or steel cord. It usually consists of two or more rollers. , arranged in a certain form, the calender can be divided into two-roll, three-roll, four-roll and five-roll calenders according to the number of rollers, and can be divided into "L" type and "T" type according to the arrangement of the rollers. , "F" type, "Z" type and "S" type, etc. The calender is mainly composed of rollers, racks, roller distance adjustment devices, roller temperature adjustment devices, transmission devices, lubrication systems and control systems.

Problems solved by technology

[0003] However, traditional rubber and plastic molding calenders are inconvenient to control the temperature of the rollers. When the temperature of the rollers is too low during the pressing process, it will easily affect the quality of the pressing, and it is not easy to clean the rubber waste on the rollers, which will easily affect the pressing effect.
