Description

Bottle blowing machine is with drawing mechanism convenient to location

Technical Field

The utility model relates to a bottle blowing machine equipment technical field specifically is a bottle blowing machine is with drawing mechanism of being convenient for location.

Background

Most plastic hollow containers are manufactured by adopting an injection molding process, and the flow of the whole working line of the bottle blowing machine is as follows: firstly, transferring the bottle blank to the bottle blank mounting end of the bottle blank seat, then heating or preheating the bottle blank, then stretching and blowing the bottle, and finally unloading the formed bottle from the bottle blowing machine.

wherein, stretching and bottle blowing are mutually precise adaptive processes, and compared with stretching, the quality of products is influenced by too late or too early entering of high-pressure gas into bottle blanks. In order to increase the production efficiency, a plurality of blowing stations are usually provided on a machine, each station consisting of a mould cavity and a stretching rod. However, in the prior art, the cylinder is adopted for most of the stretching mechanisms to stretch, the stroke of the cylinder is large, unstable phenomena occur to a certain extent during stretching, the quality of products is influenced, the working efficiency of equipment is influenced, and moreover, the traditional stretching mechanisms are complex in structure and large in maintenance difficulty.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bottle blowing machine is with tensile mechanism of being convenient for location, is faster more steady at the tensile part of whole bottle blowing. The servo motor of high-speed low power is adopted in the cooperation, and is faster than adopting the tensile speed of cylinder in the trade, and the location is accurate, and the noise is littleer.

In order to achieve the above object, the utility model provides a following technical scheme: the stretching mechanism comprises a stretching back plate, wherein three linear guide rails which are correspondingly arranged are arranged on the stretching back plate, a sliding block is arranged on each linear guide rail in a sliding mode and fixedly connected with a stretching middle plate, a stretching lower plate is fixed on the stretching back plate, a speed reduction motor is fixedly installed on the stretching lower plate, a gear is fixed at the output end of the speed reduction motor, and the gear is tightly meshed with a rack.

Preferably, a guide rod is further connected between the middle stretching plate and the lower stretching plate.

Preferably, a stretching upper plate is arranged at the top of the stretching back plate, and a servo motor is arranged on the stretching upper plate.

Preferably, one end of the rack is fixedly connected with the stretching middle plate.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model discloses compact structure, convenient to use is faster more steady at the tensile part of whole bottle blowing, and the cooperation adopts high-speed low-power servo motor, and is faster than adopting the tensile speed of cylinder in the trade, fixes a position accurately, and the noise is littleer.
