Description

Technical Field

[0001] This utility model relates to the technical field of rubber extrusion molding equipment, specifically an adjustable rubber product extrusion molding equipment. Background Technology

[0002] Rubber extruders are a fundamental piece of equipment in the rubber industry and a key component affecting product quality, playing a vital role in the production of tires and rubber products. The development of rubber extruders abroad has progressed through stages including plunger extruders, screw-type hot-feed extruders, ordinary cold-feed extruders, main and auxiliary screw cold-feed extruders, cold-feed vented extruders, pin cold-feed extruders, and compound extruders.

[0003] Extensive searches revealed that the Chinese Utility Model Patent Publication No. CN215791619U discloses an adjustable rubber extruder, comprising a main body, a cylinder at the top of the main body, a hopper fixed at the top of the cylinder, multiple slots symmetrically spaced at equal intervals inside the hopper, a metal sleeve with a circular cross-section fitted on the outer surface of the hopper, two through holes symmetrically opened inside the metal sleeve, and two fixing blocks symmetrically fixed on both sides of the metal sleeve relative to the positions of the through holes.

[0004] While the above solution offers many advantages, it also has the following drawbacks: To maintain the stability of the metal sleeve, multiple locking blocks are required to secure it. This necessitates pulling multiple levers simultaneously and maintaining the pulling position to adjust the height of the metal sleeve. This method requires multiple people to operate in coordination, and the height adjustment of the metal sleeve is limited by the positions of the various locking slots. Consequently, adjusting the height of the metal sleeve becomes very cumbersome and reduces its applicability. Utility Model Content
