Description
Technical Field
The invention relates to the field of mechanical die heads, in particular to a high-filling wood-plastic composite material granulation die head.
Background
Wood-Plastic Composites (WPC) are a new type of composite material which has been vigorously developed in recent years at home and abroad, and refer to a board or a profile which is produced by mixing polyethylene, polypropylene, polyvinyl chloride and the like instead of a common resin adhesive with more than 50% of waste plant fibers such as Wood flour, rice hulls, straws and the like to form a new Wood material, and then carrying out Plastic processing processes such as extrusion, die pressing, injection molding and the like. The content of the wood-plastic plant fiber for producing the section is usually as high as 60%, and the conventional process is mainly characterized in that the wood-plastic plant fiber is subjected to blending plasticization by a parallel double-screw extruder and then is crushed by a fan to form a crushed material and is used for producing the section. However, the process can cause serious dust loss, seriously affect the production environment and harm the health of production personnel. The wood-plastic material particles with uniform particles and low ash content are produced in a granulation mode, dust in the production process is reduced, the stability and uniformity of particle feeding in the production process of sectional materials are improved, and the production efficiency and the yield of products are improved. However, after the plant fibers are filled into the plastic matrix, the flowability of the composite material is poor, the extrusion is difficult, the extrusion pressure of the traditional bracing and granulating process is too high, the speed is low, the efficiency is low, and the production requirement cannot be met.
Disclosure of Invention
Aiming at the problems of poor flowability of the wood-plastic material, large pressure in the extrusion granulation process and difficult granulation in the prior art, the invention provides the granulation die head suitable for the high-filling wood-plastic material.
In order to achieve the purpose, the invention adopts the following technical scheme:
a high-filling wood-plastic composite material granulation die head comprises a die head frame, a material baffle plate, a discharge die, an ejector pin plate, an ejector pin rod, a cylinder, a feeding pipe, a flow distribution cone, a receiving hopper, a feeding pipe and a melt flow channel; the feeding pipe is positioned in the middle of the die head frame, the left side and the right side of the feeding pipe are respectively provided with a material baffle plate and an ejector pin rod connected with a cylinder, the ejector pin rod is connected with an ejector pin plate, and the ejector pins are fixed on the ejector pin plate and distributed at equal intervals; a receiving hopper is arranged below the discharging die opening and is communicated with the feeding pipe.
Furthermore, the material baffle can be adjusted up and down according to actual needs, so that the volume of the melt runner can be adjusted.
Furthermore, the air cylinder can drive the thimble rod to move up and down periodically.
Furthermore, the position of the thimble corresponds to a discharge mouth die which is circumferentially distributed at the bottom of the die head frame.
Furthermore, the receiving hopper is fixedly connected with the feeding pipe and is positioned right below the discharging port die.
Furthermore, a shunting cone is arranged below the feeding hole to shunt the wood-plastic composite material.
The invention has the beneficial effects that the wood-plastic composite material is used as a raw material, the ejection pins which move periodically are used for extruding a small amount of wood-plastic composite material which is continuously filled in the discharge die to prepare wood-plastic composite material particles, and the produced wood-plastic composite material particles have uniform texture, low dust, high production efficiency and stable quality.

Detailed Description
The present invention will be further described with reference to the following embodiments.
Example 1
The device comprises a die head frame, a material baffle plate, a discharge port die, a thimble, an ejector plate, an ejector pin rod, a cylinder, a feeding pipe, a flow distribution cone, a receiving hopper, a feeding pipe and a melt flow channel; the feeding pipe is positioned in the middle of the die head frame, the left side and the right side of the feeding pipe are respectively provided with a material baffle plate and an ejector pin rod connected with a cylinder, the ejector pin rod is connected with an ejector pin plate, and the ejector pins are fixed on the ejector pin plate and distributed at equal intervals; a receiving hopper is arranged below the discharging die opening and is communicated with the feeding pipe.
The material baffle plate can be adjusted up and down according to actual needs, so that the volume of the melt runner can be adjusted; the cylinder can drive the thimble rod to move up and down periodically; the position of the thimble corresponds to a discharge port die which is circumferentially distributed at the bottom of the die head frame; the receiving hopper is fixedly connected with the feeding pipe and is positioned right below the discharging port die; a shunting cone is arranged below the feeding hole to shunt the wood-plastic composite material.
After the wood-plastic composite material is mixed by an extruder, the mixture enters a solution flow channel through a feeding pipe; the ejector plate is positioned above the baffle plate, when the wood-plastic composite material flows in the solution flow channel and has a tendency of being extruded outwards after the ejection of the wood-plastic composite material through the discharge die opening, the cylinder drives the ejector pin to move up and down periodically through the ejector pin rod and the ejector plate, and the wood-plastic composite material filled in the discharge die opening is continuously extruded out of the discharge die opening, so that compact wood-plastic composite material particles are formed; the wood-plastic composite particles extruded by the discharging port die fall into the receiving hopper, air flow is blown from one end of the feeding pipe to cool the wood-plastic composite and convey the wood-plastic composite to the storage hopper, and then the wood-plastic composite is packaged and stored.
