Description

Technical Field

[0001] The utility model relates to the technical field of rubber paste production equipment, in particular to reverse coating type rubber paste production equipment. Background Art

[0002] Rubber paste refers to an external dosage form that is coated on a backing material after the drug or medicinal extract is mixed with a rubber-based matrix. Rubber paste generally uses silicone paper or tape as a carrier, and then evenly spreads the mixture of drugs or medicinal extracts and rubber-based matrix on it. When the drug is coated on the tape, reverse-coating rubber paste production equipment is used.
