Description

A plastic extrusion molding machine

technical field

The utility model relates to a plastic extrusion molding machine, which belongs to the field of environmental protection equipment.

Background technique

With the improvement of modern living standards, a large amount of household garbage and plastic products, and waste plastic items are eliminated. In order to save energy, the secondary utilization of recyclable waste plastic items is an important issue in environmental protection. At present, the injection piston of the injection molding machine must be returned to Depressurizing the cold runner, while the relatively long runner makes the return of the material difficult. A disadvantage of known injection molding machines is that waste material often remains in the duct of the injection tube after the injection operation.

Utility model content

The utility model aims at that the injection piston of the current injection molding machine must be retracted to release the pressure of the cold runner, but the rather long flow channel makes it difficult for the material to flow back. The disadvantage of the known injection molding machine is that after the injection operation A plastic extrusion molding machine was designed to solve the problem that waste material would often remain in the piping of the injection pipe.

The technical scheme that the utility model solves its technical problem to take is:

The structure of this plastic extrusion molding machine includes: a motor, a gearbox, a hopper, a barrel, a screw, and a die; the motor is a rectangular horizontal structure, and a gearbox is welded on one side of the motor, and the gearbox It is a vertical cuboid structure. A hopper is provided at the upper end of one side of the gearbox. The hopper is a funnel-type inner hollow structure. The inlet diameter at the upper end of the hopper is twice the outlet diameter at the lower end. In the same way, the barrel is a rectangular cylindrical inner hollow structure, and a screw is installed in the hollow of the barrel, and one end of the screw is connected to the transmission transmission, and the screw is installed in the hollow part of the barrel, and runs through the entire barrel of the barrel. The core, the barrel and the other top of the screw are threaded with a die.

The screw rod and the hollow cylinder surface in the barrel are in a gap-type rotating state.

The mouth die is threadedly connected with the barrel and the screw rod, and different shapes of dies can be exchanged according to requirements.

The barrel is installed on the upper end of the motor and on one side of the gearbox.

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

1. The utility model is novel and unique. When in use, the dies are threadedly connected, and the dies of the required shape can be replaced according to different needs. The overall volume is small, and the occupied space is small, which meets the production needs of small and medium-sized enterprises.

2. The utility model has the advantages of simple structure, good manufacturability of components, low material price, low manufacturing cost and wide applicability.

detailed description

As shown in Figure 1: a plastic extrusion molding machine, its structure includes: motor 1, gearbox 2, hopper 3, barrel 4, screw rod 5, die 6; motor 1 is a rectangular horizontal structure, said A gearbox 2 is welded on one side of the motor 1, and the gearbox 2 is a vertical cuboid structure. A hopper 3 is provided at the upper end of one side of the gearbox 2. The hopper 3 is a funnel-type inner hollow structure. The hopper 3 The inlet diameter at the upper end is twice the outlet diameter at the lower end. The lower end of the hopper 3 communicates with the material barrel 4. The material barrel 4 is a rectangular tubular inner hollow structure. A screw 5 is installed in the hollow of the material barrel 4. One end of the screw rod 5 is connected to the transmission box 2, the screw rod 5 is installed in the hollow part of the barrel 4, runs through the entire barrel center of the barrel 4, and the other top of the barrel 4 and the screw rod 5 is threaded with a die 6; The hollow cylinder surface of the screw 5 and the barrel 4 is in a gap-type rotating state; the die 6 is threadedly connected with the barrel 4 and the screw 5, and molds of different shapes can be exchanged according to requirements; the barrel 4 is installed on the upper end of the motor 1 , the upper side of the gearbox 2.

In the plastic extrusion molding machine described in this embodiment, when in use, the motor 1 drives the gearbox 2 to run. Driven by the variable box 2, the waste materials entered by the hopper 3 are processed by the barrel 4 and are processed according to the die The shape of 6 is processed into various required different shapes. The utility model is novel and unique. When in use, the die 6 is threadedly connected, and the mold of the required shape can be replaced according to different needs. The overall volume is small, and the occupied space is small, which meets To meet the needs of small and medium-sized enterprises, the utility model has the advantages of simple structure, good manufacturability of components, low material price, low production cost and wide applicability.

The above descriptions are only specific implementations of the utility model, and changes that can be easily conceived by those skilled in the art within the scope of the disclosure of the utility model should be covered within the protection scope of the utility model.
