Quick-open connecting structure of pelletizing die

Abstract

The invention discloses a quick-open connecting structure of a pelletizing die, which comprises a die arranged on an extruder head, a pelletizing cutter arranged on the die, and a central spindle of the die for driving the pelletizing cutter to operate. The invention is characterized in that one end of the central spindle of the die is provided with a clutch connected with a main shaft of a motor, and the central spindle of the die is connected with the main shaft of the motor by the clutch. In the invention, through arranging the clutch at the central spindle of the die, the central spindle of the die is connected with the main shaft of the motor, which facilitates the connection and disconnection of the main shaft of the motor and the central spindle of the die, thereby achieving the purpose of operating and controlling the operation of the central spindle of the die, facilitating operators to operate and maintain the extruder head, avoiding the power consumption caused by the repeat startup of the motor, and improving the work efficiency; and meanwhile, the invention has the advantages of simple structure, convenient operation, low processing cost and time and labor saving, therefore, the quick-open connecting structure is worth popularizing.

Description

technical field [0001] The invention relates to a component connection structure of an extruder, in particular to a quick-opening connection structure of a pelletizing die installed on the head part of the extruder, and belongs to the field of plastic processing. Background technique [0002] In plastic processing, extrusion molding is also called extrusion molding, which means that the material passes through the action between the barrel of the extruder and the screw, is heated and plasticized, pushed forward by the screw, and continuously passes through the machine head to make various cross-sections. A method of processing finished or semi-finished products. The head of the existing extruder consists of an alloy steel inner sleeve and a carbon steel overcoat, and a molding die is housed in the head. The function of the machine head is to transform the rotating plastic melt into a parallel linear motion, evenly and stably introduce it into the mold sleeve, and give the p...

AI Technical Summary

Problems solved by technology

The central mandrel of the die is generally driven by a motor, but the existing central mandrel of the die is connected to the motor in a fixed connection, but it is necessary to repair the die or the head part and when replacing the filter, the staff needs to stop The motor is then repaired or replaced. Sometimes it is only necessary to stop the motor for a short period of time and then restart the motor. This not only wastes electricity, increases processing costs, but also complicates the operation, takes time and effort, and affects work efficiency.
