Curve friction transportation automatic plastic container forming machines

Abstract

The curved friction pipe conveying automatic plastic container forming machine has a drawing and blowing machine seat, a template with mold, a mold clamping mechanism, a drawing and blowing mechanism, a heating mechanism with support, a plastic bottle pipe conveying mechanism with heating channel, a pipe supporting device and a conveying friction belt or chain on two sides of the heating channel, a driving mechanism to drive the conveying friction belt or chain, and an electric heater below the heating channel. It features the at least two S-shaped heating channels with one material inlet and one material outlet, the bottle pipe arranging mechanism in the material outlet, and the material feeding mechanism to convey the arranged bottle pipe into the mold of the drawing and blowing machine.

Description

technical field [0001] The invention relates to a full-automatic hollow plastic container molding machine, in particular to an automatic plastic container molding machine for curved friction pipes, and belongs to the field of plastic machinery. Background technique [0002] When processing hollow plastic containers such as mineral water bottles, the plastic raw material is first injected into a bottle tube by an injection molding machine, and then the bottle tube is heated by a heating device, and then the heated bottle tube is stretched and blown by a stretch blowing machine. The blowing machine can be divided into two pieces of equipment independently, and can also be combined together. The combination of the heating device and the blowing machine and the automatic delivery of the bottle tube are called automatic plastic container forming machines. The vast majority of existing plastic bottle tube heating devices insert the bottle tube on the support seat (bottle tube plug...

Problems solved by technology

However, the technical scheme of the friction conveying pipe previously designed is a single-track linear conveying operation, so there are the following disadvantages: one is that the heating path of the heating device is very long, especially with the stretch-blow machine that processes multiple bottles at a time (one pair of molds). Matching, that is, the so-called one out of two, one out of three, one out of four and other stretch blowing machines, it is difficult to realize if one straight-line friction conveyor is used. If multiple straight-line friction conveyors are used, not only the volume is large, but also multiple feeding The material port and multiple discharge ports are complex in structure, and installation and maintenance are very troublesome.

Second, the electric heating loss of the linear single-channel pipeline is large

At the same time, there is no arrangement mechanism for the bottle tubes at the discharge port, and only one bottle tube can be discharged at a time
