Description

Technical Field

[0001] The utility model belongs to the technical field of extruder equipment, and in particular relates to a hinged die head which is easy to reset. Background Art

[0002] After the hinged quick-open filter-changing machine head is opened, the filter screen must be quickly replaced and then quickly reset to continue production (if it is slow, the machine head will be cold and affect continued production). If the machine head is not reset well, the reset speed will be reduced (the machine head is very hot at this time), thus affecting the use; in the prior art (such as Fig.11 The swing bolt hole (as shown) matches with the swivel pin fixed on the rear plate, and the machine head is fixed with an M8 screw to the baffle. When the machine head is opened, loosen the swing bolt and nut on the other side, turn the swing bolt to make the nut on it leave the machine head, and then loosen the nut on the rotating side. At this time, the machine head can be opened. The machine head rotates on the shaft, and there is a matching clearance between the swing bolt hole and the swivel pin, and a clearance (large) between the swing bolt hole and the machine head slot, which causes the machine head to sag easily when it is opened, making it inconvenient to use.
