Abstract

An extrusion molding machine has a main extrusion molding device, and a drive mechanism connected to the main extrusion molding device. The drive mechanism has a motor device, a transmission case, and a drive shaft connected to the motor device. The drive shaft passes through the transmission case. The main extrusion molding device has an upper feed inlet, a lower chamber, and a gear mechanism therein. The gear mechanism has a first pinion, a second pinion engaging with the first pinion, a third pinion engaging with the second pinion, a main gear engaging with the first pinion, a fourth pinion engaging with the main gear, a fifth pinion engaging with the fourth pinion, a sixth pinion engaging with the fifth pinion, and a seventh pinion engaging with the sixth pinion. The main gear encloses the drive shaft.

Claims

1. An extrusion molding machine comprises:

a main extrusion molding device, and a drive mechanism connected to the main extrusion molding device,

the main extrusion molding device having an upper feed inlet, a lower chamber, and a gear mechanism therein,

the gear mechanism having a main gear and a plurality of pinions,

a feed mechanism having the main gear, a first portion of the gear mechanism, and a containing interior,

the feed mechanism adjacent to the upper feed inlet of the main extrusion molding device,

a compression mechanism disposed below the feed mechanism,

the compression mechanism having the main gear, a second portion of the gear mechanism, and a guide interior,

a blending mechanism disposed below the compression mechanism,

the blending mechanism having a third portion of the gear mechanism, and a blending spacing,

a metering mechanism disposed below the blending mechanism,

the metering mechanism having a fourth portion of the gear mechanism, and
