Description
Technical Field

Background
The conventional steamed bun type rubber extrusion forming device comprises a raw material storage barrel, a rubber block extrusion barrel, a rubber material pushing and pressing system and a rubber block cutting system; the raw material storage barrel comprises a storage barrel body and a circular basin-shaped bottom at the left side, and the sizing material pushing and pressing system comprises a hydraulic oil cylinder, a pressure push rod and a pressure push plate; the cutting system comprises a material cutting knife and a servo motor, and the servo motor drives the material cutting knife to rotate to cut extruded rubber materials; the rubber extrusion molding process is a process of filling the coupon-shaped raw materials into a raw material storage barrel, pushing and extruding the coupon-shaped raw materials by a hydraulic oil cylinder through a pressure push rod and a pressure push plate, forming strips in a rubber block extrusion barrel, and cutting the strips into rubber blocks through a rotating material cutting knife.
Conventional technology, in the steamed bun rubber piece press forming process, the connection is screwed up with the screw between the round basin shape bottom of raw materials storage vat one side and the raw materials storage staving, opens inconveniently when feeding, influences production efficiency. The originally designed steamed bun rubber block extrusion die is round steamed bun rubber, and in the pressing process of the round steamed bun rubber, the weight is not easy to control accurately, so that the quality of the rubber diaphragm of the air chamber is influenced in the process of pressing the rubber diaphragm of the air chamber by high-temperature vulcanization. In addition, in the cutting process after the steamed bun rubber materials are extruded from the extrusion die, the steamed bun rubbers are easy to adhere to each other, and cutting by a material cutting knife is inconvenient.

The weight error of the single steamed bun rubber is larger and more than 2 g when the weight is corrected by uninterruptedly manually weighing. When the rubber amount is small, the rubber diaphragm of the air chamber cannot be formed, so that the air chamber is scrapped; when the glue amount is large, the glue overflow phenomenon is generated around the die in the vulcanization pressing process, so that the later cleaning of the product is inconvenient.
