Quick release type locking device for upper die head and gun barrel of extruder

Abstract

The invention discloses a quick release type locking device for an upper die head and a gun barrel of an extruder. The device comprises a bracket, two locking blocks and two rotating shafts are arranged on the bracket, threads and nut blocks are arranged on the left part and the right part of each rotating shaft, the threads on the left part and the right part of each rotating shaft are arranged in opposite rotating directions, the threads on the same side of the two rotating shafts are arranged in the same rotating direction, the two locking blocks are arranged on the left side and the right side of a gun barrel respectively and located between the two rotating shafts, the upper end and the lower end of each locking block are fixed to the upper nut block and the lower nut block on the corresponding side respectively, a force exerting mechanism is arranged at one end of at least one rotating shaft, a transmission mechanism is arranged between the two rotating shafts, arc-shaped grooves are formed in the opposite side surfaces of the two locking blocks, and the device also comprises a front annular plate fixed on the die head and a rear annular plate fixed on the gun barrel. According to the quick-release locking device, the die head and the gun barrel can be quickly locked or separated through approaching or leaving of the two locking blocks, so that the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of extruders, in particular to a quick-release locking device for an upper die head and a barrel of an extruder. Background technique [0002] During the maintenance of the extruder, it is often necessary to remove the die head from the barrel in order to clean the porous filter plate between the die head and the barrel. Usually, the die head and the barrel are connected and locked by six screws passing through them. Together, during maintenance, it is necessary to disassemble the six screws before the die head can be removed, which will be cumbersome and will reduce the efficiency of maintenance work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quick-release locking device for the upper die head and barrel of an extruder that can quickly disassemble or lock the die head. [0004] In order to solve the above problems, the technical solution adopted ...
