Two-way positioning inserter-type bottle blank seat pushing mechanism

Abstract

The invention discloses a two-way positioning inserter-type bottle blank seat pushing mechanism comprising a cylinder fixing plate and left and right sliding tracks, which are arranged on a stepping base plate. A pushing cylinder is arranged on one side of the cylinder fixing plate, and the piston rod of the pushing cylinder is connected with a floating adapter. Left and right moving sliding plates are arranged on the left and the right sliding tracks, front and back sliding tracks are arranged on the left and the right moving sliding plates, a front sliding plate and a back sliding plate are arranged on the front and back sliding tracks, a bottle blank seat inserter and a front cylinder connecting plate are arranged on the front sliding plate, a bottle blank seat insertion groove is formed on the bottle blank seat inserter and engaged with a bottle blank seat, a chain inserter and a back cylinder connecting plate are arranged on the back sliding plate, a chain insertion groove is formed on the chain inserter and engaged with a delivery chain, and a two-way synchronous reciprocating cylinder is arranged on one side of the left and the right moving sliding plates. The two-way synchronous reciprocating cylinder comprises left and right cylinder bodies, left and right end covers are arranged on the left and the right cylinder bodies, left and right gas inlet holes are formed on the left and the right end covers, a middle gas inlet hole is formed on a middle end cover which is arranged between the left and the right cylinder bodies, a left piston is arranged in the left cylinder body and connected with the front cylinder connecting plate, and a right piston is arranged in the right cylinder body and connected with the back cylinder connecting plate.

Description

technical field [0001] The invention relates to a bottle blowing machine, in particular to a two-way positioning plate type preform seat pushing mechanism of the bottle blowing machine. Background technique [0002] Plastic raw materials such as PET are used to process them into hollow containers such as mineral water bottles and oil bottles through injection stretch blowing. First, the plastic raw materials are injected into preforms by injection molding machine. The machine stretches and blows the heated preform. The conveyor chain in the heating tunnel of the existing equipment is driven by the servo motor to rotate the gear, and the gear drives the conveyor chain to run. The disadvantage of this structure is: when the voltage is unstable, it is easy to cause the servo motor speed to be inaccurate, so that the motor installed on the conveyor chain The preform seat on the top cannot correspond to the blowing mold, so that the preform cannot enter the blowing mold, and the...
