Description
Technical Field
The invention relates to rubber extrusion equipment, in particular to a quick-opening rubber extruder head.
Background
In the existing hydraulic locking rubber extruder head, a plugboard with an included angle of about 10 degrees is adopted to lock the die plate, and when the plugboard is inserted into place to tightly press the die plate, the die plate is simultaneously locked, so that the glue leakage phenomenon can not occur at the die of an extrusion outlet (a collection port of a plurality of flow channels in an extruder die body) of the extruder head; because of the included angle of about 10 degrees, when the inserting plate leaves the opening template, the locking of the mouth-shaped template is lost instantaneously, and the hot glue in the molten state in the extrusion port of the machine head can infiltrate into the locking surface of the mouth-shaped template.
The structure is unfavorable for the replacement of the specification of the part extruded product, because only the die plate needs to be replaced at the moment, the die frame plate does not need to be opened, but due to the seepage of hot glue, when the plugboard locks the die plate and the die frame plate again, the seepage layer of the hot glue can cause the leakage channel to occur at the locking part of the die frame plate, so that the glue leakage phenomenon occurs in the extrusion operation.
Therefore, when the specification of the extruded product is changed, besides the die plate, the die plate and the die plate can be folded and locked after the die plate is opened to clean the sizing material on the locking surface, so that the shutdown treatment time is as long as 2-5 minutes, and the working efficiency of the rubber extruder is seriously influenced.
In order to solve the above problems, the present application unit proposes an invention patent application (application number 201410389000.5) of a machine head of a rubber extruder, and discloses a technical scheme for rapidly replacing a die plate without opening a die frame plate, wherein the insert plate and the die frame plate are provided with a pair of surfaces which are opposite to each other and can be locked with the die frame plate and a pre-die plate by moving the insert plate, and the insert plate and the die plate are provided with a pair of surfaces which are opposite to each other and can be locked with the die plate by moving the insert plate.
The above technical solution is theoretically possible, but in the practical application process, two mating surfaces forming an angle of 10 ° are simultaneously provided on the same mating surface, and if the pair of mating surfaces opposite to each other cannot be accurately repaired, the following results occur: firstly, the smooth insertion of the inserting plate can not be ensured, and secondly, the phenomenon of front leakage on the matching surface of the mouth frame plate and the die body can not be effectively ensured.
Therefore, the technical proposal of the invention patent application of the nose of the rubber extruder has certain difficulty in practical application.
