AI Technical Summary
Technical Problem
The existing tobacco feeder's airlock channel has poor sealing performance, is prone to leakage, has a complex structure, and is easily worn, affecting the efficiency and uniformity of tobacco conveying and increasing maintenance costs.
Method used
A locking device for the airlock channel opening, comprising a U-shaped mounting shell, a locking mechanism, and a push rod, is designed. The arc-shaped fixing part grips the connection between the airlock channel and the air source end through a linkage mechanism and transmission components, preventing loosening and leakage.
Benefits of technology
It improves the sealing and stability of the airlock passage, prevents leakage, simplifies the structure, and reduces maintenance frequency and cost.

Abstract
The utility model relates to the technical field of tobacco processing equipment, and discloses a tobacco shred supply machine air brake channel opening locking device which comprises a U-shaped installation shell, a U-shaped locking piece, a U-shaped locking piece, a U-shaped locking piece and a U-shaped locking piece. The U-shaped installation shell is fixedly installed outside a tobacco shred supply machine, and an opening of the U-shaped installation shell faces an air brake channel. The locking mechanism comprises screw rods and arc-shaped fixing pieces, the two screw rods are rotationally arranged on the two sides of the upper end of the U-shaped mounting shell respectively, each screw rod is in threaded connection with a threaded block, and the arc-shaped fixing pieces are fixedly arranged on the two threaded blocks; the ends, away from the screw, of the two arc-shaped fixing pieces penetrate out of the opening of the U-shaped mounting shell outwards and then are connected with the outer surface of the air brake channel. A through hole is formed in the end, away from the air brake channel, of the U-shaped installation shell, the push rod is arranged at the through hole in a sliding mode, and linkage mechanisms are arranged at the two opposite ends of the push rod to be connected with the screws on the corresponding sides. The air brake channel opening can solve the problems that an existing air brake channel opening of the wire supply machine is not good enough in sealing performance, complex in structure and prone to abrasion.
