Description

Machine head opening and closing device for sheet production of rubber extrusion tubular machine head
Technical Field
The invention relates to a machine head opening and closing device for producing sheets by using a rubber extrusion tubular machine head, belonging to the technical field of rubber extrusion processing equipment.
Background
The rubber sheet is usually produced by extrusion or calendering. The former is generally suitable for directly extruding thicker films, and the latter is often used for rapidly producing thinner films with high dimensional accuracy. However, in some cases where a relatively large width rubber sheet is produced using a relatively small screw diameter extruder, a process of producing the sheet using a rubber extrusion tube head is generally employed, that is: firstly, extruding a rubber tubular blank through a tubular neck mold arranged at the outlet of a hot feeding or cold feeding extruder; then, cutting the sheet by a cutter, and flattening the sheet to obtain a flat sheet, as shown in fig. 1; finally, the semi-finished product of the film is obtained after cooling, fixed length cutting or curling.
In such a "tube-to-tube" die apparatus, a core die for forming the inner diameter of a tubular blank is usually fixedly mounted in a die flow passage by a core die holder. This increases the flow resistance of the rubber melt in the runner and easily causes a problem of poor melt fusion, and it is difficult to water-cool the core. In order to overcome the above problems, it is necessary to arrange a fixing holder supporting the tubular extrusion core type outside the flow passage of the head. In such a case, it is often necessary to open and close the tubular head in order to stop the cleaning of the head or to change the specification or the kind of the tubular blank in the actual production process. How to quickly move the core mold out of the flow passage of the machine head and accurately move the core mold into the flow passage of the machine head is a key operation for opening and closing the tubular machine head, as shown in fig. 2. In the conventional rubber extrusion tube-type die, no matter whether the core mold support is in the runner or outside the runner, the core mold is moved out and in by manual operation, which has the disadvantages of high labor intensity, long time and low safety, especially for large-sized core molds.
