Description

Technical Field

[0001] The utility model relates to the field of rubber cleaning devices, in particular to a rubber preforming machine die head rubber cleaning device. Background Art

[0002] The rubber preforming machine is composed of a hot melt chamber, an extrusion pushing mechanism and a die head, so that under the action of the extrusion pushing mechanism, the rubber material inside the hot melt chamber is extruded and discharged through the die head, so that the rubber material is discharged into a pre-finished product.

[0003] When the rubber preforming machine stops, foreign matter, equipment failure and other factors cause the die head to be clogged, it is necessary to remove the rubber material head inside the die head. When removing the clogged material head inside the die head, the die head is usually disassembled from the rubber preforming machine, and then a rod-shaped object is directly used to squeeze and push the material head inside the die head, so as to squeeze out the clogged material head inside the die head. However, directly using a rod-shaped object to push and extrude the cavity on the die head will cause friction and scratches between the rod-shaped object and the inside of the die head cavity, thereby causing damage to the die head. It is not convenient to push out and clean the clogged material head in the inner cavity in a straight line according to the holes on the die head. Utility Model Content
